Cushion material, manufacturing method of cushion material, laminate, manufacturing method of laminate, usage of cushion material, connection structure of shelter compartment, formation method of shelter compartment, disassembly and storage method of shelter compartment, and shelter How to form a shock absorbing wall panel

The present invention is lightweight and has a linear pattern by exposing a fusion layer or an adhesive layer on a wavy uneven structure surface made of a polyolefin resin foam that can be used as a mat material or partition material. An excellent cushion material, a laminate using this, a method for manufacturing the cushion material and the laminate, a method for using the cushion material, and a laminate that can be easily assembled without using an assembly tool or an assembly part are used. The present invention relates to a connection structure of evacuation shelters, a method of forming an evacuation shelter section using a laminate, a method of disassembling and storing the evacuation shelter section, and a method of forming a shock absorbing wall panel of an evacuation shelter.

Conventionally, cushioning materials using resin foam have been used as packaging materials, mats, and the like. For example, as a cushioning material using such a resin foam, a cushioning material having a mountain valley uneven shape formed on the surface is used.

Such cushioning materials are widely used, for example, as materials for various industrial products such as cushioning materials, building materials, heat insulating materials, and sound deadening materials, or as materials for various household products such as daily necessities, sports and leisure products, and sports products. There is a thermoplastic resin foam sheet having an uneven surface with a skin (Patent Document 1).

In the method for producing a thermoplastic resin foam sheet of Patent Document 1, first, a strip-shaped thermoplastic resin foam sheet having a uniform thickness is cut in a concave-convex shape in the middle in the vertical direction and divided into two upper and lower layers, or uniformly. A strip-shaped thermoplastic resin foam sheet having a large thickness is held in an uneven shape, and the middle part in the vertical direction is cut horizontally to divide the sheet into two upper and lower layers. As a result, two foam sheets having an uneven surface on one side are molded. Next, heat energy is radiated to the uneven surface of the foamed sheet to melt and cool the surface. As described above, a thermoplastic resin foam sheet having an uneven surface with a skin is formed.

Further, a soundproof floor structure in which a hard plate is laminated on a plastic foam, which can be suitably used as a floor material for various houses and warehouses, such as a floor material for an apartment house such as an apartment, has been proposed. (Patent Document 2).

Normally, if a relatively hard material is used as a finishing material for a floor substrate such as a concrete slab, daily noise is transmitted downstairs as solid sound, which causes a problem of environmental deterioration. As soundproofing means for these, various base materials such as polyurethane foam, synthetic fiber non-woven fabric, and polyethylene foam have been conventionally developed and used as floor base materials.

On the other hand, Patent Document 2 is a soundproof floor structure using a floor base material in which a hard plate is laminated on a floor base material made of a foam having valleys and / or peaks on the surface. In Patent Document 2, a hard plate is laminated on a plastic foam having a compressive hardness of 0.5 to 1.5 kg / cm ² , an apparent density of 0.05 to 0.12 g / cm ³ , and a hardness of 5 to 35. It uses a floor base material, does not impart designability as in the present application, and does not use only foamed resin as the cushion material or laminate as in the present application.

In addition, cushioning materials such as mattresses and pillows are widely used in fields such as medical materials, and laminated foams having excellent body pressure dispersibility and methods for producing them have been proposed (Patent Document 3).

In Patent Document 3, a high-resilience foam having a mountain-valley surface and a polyurethane foam having a rebound resilience of 10% or less, which is closely bonded to the mountain-valley surface of the high-resilience foam, are low-resilience foam. Sufficient performance is ensured by integrating the body with the high-resilience foam by insert molding. Patent Document 3 is used in a state where a low-resilience foam and a high-resilience foam have mountain and valley surfaces in combination, and the stress of the low-resilience foam on the upper surface is supported by the high-resilience foam. The purpose is to disperse the stress. The soundproof floor structure of Patent Document 3 is not intended to improve the design property by the linear pattern on the design surface.

Further, Patent Document 4 discloses an invention relating to a method for manufacturing a cushion material in which a large number of corrugated uneven structures are periodically formed by profile processing in an island shape, and a foam material having a high hardness is arranged in a convex portion. Proposed. (Patent Document 4)

Patent Document 4 prepares a three-layer foamed resin laminate in which a hard soft foam or a semi-hard foam is bonded to the upper and lower sides of the soft foam in order to stabilize the hardness of the convex portion of the profiled wavy concave-convex structure. This is obtained by profile processing so as to straddle the upper and lower hard soft foams or semi-hard foams. However, in the manufacturing method of Patent Document 4, the fusion layer or the adhesive layer has a wavy uneven structure. It is not exposed to the surface to form a large number of annular linear patterns.

Further, in Patent Document 5, a wavy uneven structure continuous in the width direction is formed on the surface by profile processing, and a predetermined foam is arranged at a predetermined position of the wavy uneven structure to improve the design. The foam mat to be used is described. (Patent Document 5)
Further, Patent Document 6 discloses a corrugated cardboard bed in which nearly 20 members can be assembled and the length of the bed can be expanded and contracted so that the bed can be assembled without using a fixture such as tape. (Patent Document 6)
Patent Document 7 discloses a corrugated cardboard bed including a pedestal formed by assembling a plurality of corrugated cardboards of 10 or more and a top plate. (Patent Document 7)

Patent Document 8 discloses an invention in which a corrugated cardboard partition plate is used to form an evacuation shelter section. In the present invention, an assembling shelter section can be obtained by using a corrugated cardboard connecting member in the straight portion and the bent portion of the upper part and the lower part in order to connect the adjacent partition plates. (Patent Document 8)
In Patent Document 9, a corrugated board plate material having creases having a constant width along the length direction of the corrugated cardboard is repeatedly bent in a wavy shape along the creases to bond partition units that ensure uprightness to each other. A partition structure for evacuation shelters, which is characterized by joining with a corrugated cardboard, is disclosed. (Patent Document 9)

Patent Document 10 is a partition material that can be bent at a predetermined angle using a foamed resin having a spindle-shaped closed cell and having a predetermined strength that can be used in an evacuation site in the event of a disaster, and a face material is attached to the surface thereof. Things are disclosed. (Patent Document 10)

In the mat material of Patent Document 5, a continuous periodic wavy uneven structure is formed on the surface of the mat material so as to cross the foam material in the width direction, and at that time, a multi-layer resin foam having different colors is formed. By profiling the multilayer resin foam or laminate in which the bodies are laminated, a three-dimensional strip-shaped two- or three-row pattern is formed in the periodic structure of the unevenness, or instead of forming the pattern, different types are formed. The invention of assembling the foaming agent of the above is disclosed, but in the invention of Patent Document 5, the fusion layer or the adhesive layer is exposed on a wavy uneven structure surface to form a large number of annular linear patterns. is not it. Further, as the usage, the usage of a thin-walled foaming material such as an entrance mat, a bath mat, or a flooring mat for dining is described, and it cannot be used for a partition of an evacuation shelter because it does not have self-sustaining assembly.

In addition to the above cushioning materials and flooring materials, corrugated cardboard beds and partitions are used for the flooring materials and partition members of evacuation centers as described in Patent Documents 6 to 9. In the case of corrugated cardboard flooring, it is not possible to maintain a comfortable living environment for evacuees who use evacuation shelters because it requires assembly work for a large number of members, has high moisture absorption and does not have cushioning properties. In addition, there are partition partitions and floor mats that use plastic sheets, but in this case, the resin sheet for partition weighs about 10 kg, which requires joint parts and is not easy to assemble. As described above, until now, there has been no product that is lightweight, can be used as both a floor mat and a partition that can be used instead of a bed, has excellent assembly independence and moisture resistance, and has sufficient cushioning properties.

The partition material of Patent Document 10 can be used as a floor material, but it cannot be used as a bed because it is not a cushion material or a laminated body having a thin thickness and excellent design and profile processing, and is a foam. It does not have a design in itself. An adhesive or fixing means is required at the time of assembly, but in the present invention, the laminates of the present invention can be assembled simply by abutting or fitting them to each other, which is different from the present invention and Patent Document 10.

According to the cushioning material of the present invention and the laminated body using the same, a large number of annular linear patterns formed by a fusion layer or an adhesive layer are formed, which is lightweight and has excellent design and cushioning properties. It is also excellent in heat insulation and moisture resistance, and it can provide a mat material that eliminates the drawbacks of conventional corrugated cardboard flooring materials, and at the same time, it is also excellent in assembly independence at the time of assembly, so it is used for shelter compartments. It is possible to provide cushioning materials and laminates that can also be used for partitions, and it is easy to assemble and store.

However, Patent Documents 1 to 3 relate to resin foams having a periodic wavy uneven structure on the surface, but all of them are used for applications having cushioning properties without quality requirements for appearance. It is only used. For this reason, the resin foam has not been used with a design property. For example, when used as a cushioning material for packaging materials, design is not required, and when used for bedding mats, the cushioning material itself is not exposed, so until now, designs such as patterns have been used. Giving sex has never been considered.

Further, Patent Document 4 is an invention in which foam materials having different hardness are arranged at predetermined positions on a wavy uneven structure surface by profile processing, and Patent Document 5 is continuous in the width direction on the surface by profile processing. A corrugated concavo-convex structure is formed, and a predetermined foam is arranged at a predetermined position of the corrugated concavo-convex structure to improve the design. In both inventions, the fusion layer or the adhesive layer is colored. By profiling the laminated foam with the fusion layer or the adhesive layer sandwiched between them, a large number of annular linear patterns are formed on the wavy uneven structure surface to improve the design. Furthermore, it does not impart functionality to the fusion layer or the adhesive layer. Patent Documents 6 to 9 do not use a resin foam, are not excellent in design, require assembly work of a large number of members, have high hygroscopicity, and do not have cushioning properties. It is not possible to maintain a comfortable living environment for evacuees who use the. In Patent Document 10, the foam itself is not excellent in design, is not profiled, and cannot be used as a bed.

The present invention has been made in view of such a problem, and in order to improve the appearance of the cushion material, an annular layer or an adhesive layer is exposed on the surface of the corrugated uneven structure of the cushion material. A large number of linear patterns are formed to improve the design, and at the same time, it is lightweight and has excellent design, and at the same time, it has excellent moisture resistance by using a polyolefin resin foam for the cushion material, and vibration control is applied to the adhesive layer or the fusion layer. Cushion material, laminate, manufacturing method of cushion material and laminate, usage of cushion material, connection structure of evacuation shelter section using laminate, laminate, which can have functionality such as property and sound insulation It is an object of the present invention to provide a method for forming an evacuation shelter section, a method for disassembling and storing the evacuation shelter section, and a method for forming an impact cushioning wall panel of the evacuation shelter.

In order to achieve the above-mentioned object, in the first invention, the polyolefin resin foam forming the peak portion and the polyolefin resin foam forming the valley portion are laminated and formed on the laminated surface of the polyolefin resin foam. A cushioning material made of a polyolefin resin foam comprising an adhesive layer or a fusional layer, wherein one surface of the cushioning material is a wave in which peaks and valleys are alternately arranged in the vertical and horizontal directions. A profiled surface of a concave-convex structure having a shape, the other surface is a flat surface, and the adhesive layer or the adhesive layer formed substantially parallel to the other surface at a predetermined height portion of the surface of the wavy uneven structure. The fused layer is exposed, and a large number of annular linear patterns are formed at predetermined intervals from each other, and the linear pattern partitions the peak portion and the valley portion of the wavy uneven structure. , A cushioning material characterized in that it is formed at a predetermined height between the mountain portion and the valley portion so as to surround each of the mountain portions. In particular, the cushion material is not only used as a partition wall for evacuation shelters, but also has excellent design, heat insulation and moisture resistance, and can be used as a bed substitute because it is made of foam material and profiled. Can be suitably used as a mat for disasters.

By doing so, a large number of two-dimensional annular linear patterns can be formed on the surface of the cushion material by coloring them at a predetermined height at predetermined intervals. The position of forming the linear pattern formed in a ring shape at a predetermined height can be arbitrarily adjusted between the peak and the valley.

The linear pattern is formed by a fusion layer or an adhesive layer, and when the linear pattern is formed by the fusion layer, at least one fusion surface of the resin foam to be fused is painted in a different color. It may be formed by being fused using the resin foam, or when the linear pattern is formed by an adhesive layer, the adhesive layer is formed by using a colored adhesive. It may be one of the above. The linear pattern can be colored by painting the fused surface, and the adhesive layer can be colored in any color by using a colored adhesive.

The fusion layer or the adhesion layer is a fusion layer, and the fusion layer crystallizes when the surface of the resin foam forming the fusion layer at the time of fusion crystallizes in the process of melting and solidifying. It may be selectively formed into different colors by superimposing changes in degree and molecular orientation, and in addition, a residual effect of ADCA (azodicarbonamide) on the foam surface. Specifically, in addition to the change in the crystallinity and molecular orientation of the fused layer in the recrystallization process of the surface of the uncolored white resin foam by fusion, the residual effect of ADCA on the foam surface is exhibited. It can be used to selectively discolor and color yellow. Here, the surface of the foam is easy for the foamed gas near the surface of the foam to escape, and it is possible to suppress the consumption of the foaming agent ADCA as compared with the inside of the foam.

At this time, in the case of coloring by crystallization during fusion solidification of the fusion layer, for example, by melting an uncolored white resin foam, the resin foam surface and the fusion portion are fused when the resin is fused. Since it is remelted and recrystallized, the fused portion can be colored yellow by superimposing the crystallization state, molecular orientation, residual effect of ADCA on the foam surface, and the like. In this way, the change in color of the fusion layer at the time of fusion may be utilized. Alternatively, a resin foam whose surface is painted in a predetermined color may be adhered. Further, when the cushion material is formed by adhesion, a similar linear pattern can be formed by including a pigment of a predetermined color, for example, a pigment such as yellow or red, in the adhesive.

The one surface of the cushioning material is formed by the mountain portion formed by the resin foam above the linear pattern, the linear pattern forming portion on which the linear pattern is formed, and the lower portion of the linear pattern. It is divided into three portions with the valley portion formed by the resin foam on the side, and the valley portions are continuously integrated with each other by adjacent valley portions, and the linear pattern forming portion is described as described above. A three-dimensional three-dimensional pattern may be formed by forming either the mountain portion or the valley portion in a different color.

At this time, when forming a linear pattern with different colors from the peaks and valleys, the peaks or valleys and the adhesive are colored with a pigment to form a surface, or foaming to form a fusion layer. The adherend surface of the body may be colored by painting before fusion.

In addition to the two-dimensional pattern of the linear pattern forming portion, both the peak portion and the valley portion of the wavy uneven structure are colored in different colors, whereby the linear pattern forming portion and the said A cushioning material having a three-dimensional three-dimensional pattern in which both the mountain portion and the valley portion are colored in different colors may be used.

The formation height of the linear pattern can be formed at an arbitrary height within the range of the wavy uneven structure, and the linear pattern is formed from the center of the height of the wavy uneven structure. , The linear pattern or the colored mountain pattern can be made smaller by forming the mountain side, or the linear pattern can be formed from the center of the wavy uneven structure. By forming on the valley side, it may be possible to form the linear pattern or the colored mountain pattern in a large size. The wavy uneven structure can be formed by profile processing, and the size of the annular pattern of the linear pattern can be changed by adjusting the formation height of the wavy uneven structure.

The raw material resin of the resin foam may be at least one of polyethylene, low-density polyethylene, high-density polyethylene, ethylene-vinyl acetate copolymer, or polypropylene resin, or a mixture of two or more thereof. Further, the resin foam is provided with a polyethylene resin or a polypropylene resin having a carboxy group such as maleic anhydride or a functional group having an acid anhydride structure in order to improve the fusion property of the raw material resin at the time of fusion. It may contain a fixed amount. Here, the predetermined amount is the compounding ratio of the polyethylene resin or polypropylene resin having a carboxy group such as maleic anhydride or a functional group having an acid anhydride structure when the total compounding amount of the raw material resin is 100 parts by mass. The resin contains 0.5 parts by mass or more and 10 parts by mass or less, but it is preferably 5 parts by mass or less.

The resin foam is a polyethylene resin foam, and the polyethylene resin foam has a closed cell structure having a foaming ratio of 20 to 40 times, and further has a compression set of 3.0% to 7 based on JIS K6767. It is 4.4%, and the compressive stress at 25% compression at a test temperature of 25 ° C. may be 34 kPa to 56 kPa.

The corrugated uneven structure may be one in which functionality is imparted to the adhesive layer of the cushion material.

The adhesive layer is formed on the laminated surface of the resin foam by an adhesive, and at least one selected from the group consisting of urethane resin, vinyl acetate emulsion, acrylic resin, silicone resin and modified silicone resin is formed on the adhesive layer. By using an adhesive containing a flexible resin as a main component, vibration damping properties are imparted, or an acrylic acid ester-based polymer, a halogen-containing phosphoric acid ester, and an inorganic flame retardant are contained as essential components. Flame retardancy and vibration damping properties may be imparted by using an adhesive.

The resin foam can be easily prepared by dispersing any of silica, zirconium phosphate, zeolite, zinc sulfate, and zirconium sulfate as a deodorant in a predetermined amount. Further, the resin foam is an amorphous calcium phosphate particle that adsorbs or carries silver ions as an antibacterial agent or an antiviral agent, titanium oxide particles having an anatase-type crystal structure having a photocatalytic action, or a metal of silver, copper, or zinc. A predetermined amount of compound particles and metal fine particles of silver, copper, and zinc may be dispersed. The content of these deodorants and antibacterial agents may be in the range of 0.5 parts by mass to 10 parts by mass with respect to 100 parts by mass of the resin component, but is in the range of 0.5 parts by mass to 5 parts by mass. Is preferable.

The cushion material may be used as a disaster mat material with the surface on which the corrugated uneven structure is formed as the upper surface and the other surface as the lower surface. Since the cushion material is formed of a profiled foam material, it can be used in place of a bed. Therefore, the evacuation shelter section can be effectively used without providing a space dedicated to the bed in each section of the evacuation shelter.

According to the first invention, an adhesive layer or a fusion layer is exposed on a portion of a surface of a wavy uneven structure at a predetermined height, and a large number of linear patterns are formed in an annular shape separated from each other by a predetermined distance. Therefore, the design is high. Therefore, a cushion material suitable for exposed use can be obtained. The cushion material of the first invention is cut in a straight line by connecting the inflection point positions of the profiled surface of the cushion material so that the cross-sectional area of the substantially parallel portion occupying the end surface of the cushion material is maximized. It is desirable to have.

Further, the linear pattern is formed by the fusion layer or the adhesive layer exposed on the surface of the wavy uneven structure, thereby partitioning the peaks and valleys of the wavy uneven structure, and each peak is separated. By forming the ring at a predetermined height so as to surround it, the design can be enhanced. Further, by fusing the resin foam whose surface is the fusion surface of the resin foam to be fused, or by using the resin foam that forms an adhesive layer colored with a pigment or paint, the wire is used. The pattern can be colored in any color. For example, as a basic configuration of the linear pattern of the present invention, if the fused layer or the adhesive layer is colored, the foam bonded by sandwiching the fused layer or the adhesive layer may be uncolored white. In this case, if the fusion layer or the adhesive layer is colored blue or yellow, a large number of blue or yellow annular patterns are formed at predetermined positions in the mountainous portion of the wavy uneven structure, and the other parts are formed. A white cushioning material can be obtained.

Here, when the linear pattern is formed by the fusion layer, the crystallinity, the change in molecular orientation, and the residual effect of ADCA on the foam surface due to the solidification and crystallization process after melting without coloring at the time of fusion. Since only the fused surface is selectively colored, it is not necessary to apply a pigment or paint to the surface of the foam to be fused.

Further, one surface of the cushioning material is divided into three portions of a mountain portion, a linear pattern forming portion and a valley portion, and at least one or two of the peak portion or the valley portion is relative to the linear pattern forming portion. If two parts are formed in different colors, it becomes possible to form a three-dimensional three-dimensional pattern in addition to a large number of annular patterns formed on the same two-dimensional plane, resulting in higher design. Obtainable.

In addition, by changing the height at which the linear pattern of the cushion material is formed, it is possible to change the size of the linear pattern and the surface area of the colored portion in the mountain or valley portion, which changes the design. Can be done.

Also, if the resin foam is polyethylene, it is difficult to absorb water, so it is ideal for exposed use. On the other hand, if the resin foam is a urethane-based resin, it is hydrolyzable and is usually an open-cell resin foam, so that it is not suitable for exposure use. In this way, various polyolefin-based resins can be used for the resin foam, but if closed-cell foamed polyethylene is used, the cushioning material does not absorb moisture, providing a comfortable sleeping environment and living environment. Can be provided. Further, if the resin foam contains a predetermined amount of a polyethylene resin or polypropylene resin having a carboxy group such as maleic anhydride or a functional group having an acid anhydride structure, the fusion property on the fusion surface is improved. More preferred.

If the resin foam is a polyethylene resin foam having a closed cell structure, the compression set has a compression set of 3.0% to 7.4% based on JIS K6767, and the compression is 25% at a test temperature of 25 ° C. When the compressive stress is 34 kPa to 56 kPa, appropriate cushioning and moisture resistance can be ensured.

Further, if the adhesive layer of the cushion material is provided with functionality, it is possible to impart vibration damping property, flame retardancy, etc. in addition to cushioning property as well as design property. It is desirable that the total occupancy ratio of the adhesive layers, which is the ratio of the total area of the adhesive layers arranged on substantially the same plane to the total area of the cushion material in a plan view, is high because the functionality can be enhanced.

In particular, an adhesive containing a specific flexible resin as a main component is used for the adhesive layer of the resin foam, or an adhesive containing an inorganic flame retardant in an acrylic resin or a halogen phosphate ester resin is used. As a result, vibration damping and flame retardancy can be imparted to the adhesive layer. In this way, it is effective to impart these effects to the adhesive layer.

Further, the resin foam used for the cushion material or the laminate adsorbs either silica, zirconium phosphate, zeolite, zinc sulfate, or zirconium sulfate as a deodorant, or silver ions as an antibacterial agent or an antiviral agent. Alternatively, a predetermined amount of any of the supported amorphous calcium phosphate particles, titanium oxide particles having an anatase-type crystal structure having a photocatalytic action, metal compound particles such as silver, copper and zinc, and metal fine particles of silver, copper and zinc is contained. This makes it possible to impart a deodorant effect, an antibacterial effect, and an antiviral effect to the cushion material.

Examples of organic-derived materials and salts having excellent antiviral properties include alkylbenzene sulfonic acid compounds, alkali metal salts such as sodium salts and potassium salts, alkaline earth metal salts such as calcium and barium, and sulfonic acid surfactants. However, it is also considered effective to apply an aqueous emulsion of these compounds to the surface of the cushioning material. Alkylbenzene sulfonic acid compounds having excellent antiviral properties are more preferable.

The second invention is a laminate composed of the cushion material and the sheet-like resin foam according to the first invention, and is formed on the other flat surface of the back surface of the cushion material having the wavy concave-convex structure. The laminated body is characterized in that a sheet-shaped resin foam made of yet another polyolefin resin is laminated and adhered or fused. For example, the average thickness of the laminate is 20 mm or more and 50 mm or less, but preferably 20 mm or more and 40 mm or less. This is because if the average thickness of the laminate is 20 mm or less, the heat insulating property and the moisture proof property are insufficient and it is not suitable for use as a bed. Further, if it exceeds 40 mm, the laminated body becomes heavy, the assembling property is lowered, and the cost is increased at the same time. Here, for example, the weight of the laminate having a foaming ratio of 30 times and the dimensions of the laminate being 1800 mm in length × 880 mm in height × 30 mm in peak thickness (average thickness: 25 mm) is 1.25 kg, which is an average. When the thickness is 50 mm, the weight of the laminate is 2.5 kg.

The other sheet-shaped resin foam of the laminated body may have a higher strength or the same strength as the resin foam having the wavy uneven structure. Hard means reducing the amount of deformation with respect to the same compressive load, and equivalent strength means the strength of a material having the same amount of deformation with respect to the same compressive load.

For example, if the resin foam has the same composition, the resin foam can be made hard by setting the foaming ratio low. Hereinafter, the description of the resin foam is a laminate in which the cushion material having a wavy uneven structure in which the linear pattern is formed and another sheet-like resin foam are adhered or fused to the flat surface of the cushion material. It shall refer to the resin foam used for both bodies.

The laminate can be used as a disaster mat material that can be used as a partition side wall or a bed for a shelter in the event of a disaster, and can normally be used as a wall panel material for shock absorption. Here, the partition for division can be used as a partition for household division that divides evacuees for each household at the time of evacuation.

The laminate uses a resin foam having a foaming ratio of 40 times or less, and the back surface of the laminate with respect to the height (Hv) from the flat surface of the sheet-like foam on the back surface of the laminate to the valley portion of the laminate. Assuming that the ratio of the height from the flat surface of the sheet-shaped foam to the center line height (Hc) of the wavy uneven structure surface is R, if R satisfies 50% or more, the lamination is excellent in assembly independence. It can also be a body.

Here, (HC) is the height (Hm) from the flat surface of the sheet-like foam on the back surface of the laminate to the mountain portion of the laminate, which will be described later, and the flat surface of the sheet-like foam on the back surface of the laminate. It is the average height from the height (Hv) from the height to the valley of the laminated body. That is, it is the ratio of the average height of the profiled surface to the valley of the profiled surface from the back surface of the laminate, which is the average height (center line height) of the profiled surface and the profile non-processed surface. Corresponds to the height ratio of.

In the present invention, assembling independence means that the length of the long side of a predetermined dimension is twice the length of the short side, and the side end of the short side and the side of the short side of the back surface of the laminated body are fixed ends. This means that the free end, which is the end face of the short side on the opposite side of the laminate, does not bend or bend when assembled by a simple fixing means by abutting at a substantially right angle, which makes it easy to assemble the partition for partitioning. It means that it can be done stably. Here, as the simple fixing means, a hook-and-loop fastener can be used, but in addition to the hook-and-loop fastener, a simple fixing means such as a button-shaped fastener (also referred to as a snap fastener) or a tape-shaped member to which a magnet is fixed is also used. Is possible. Hereinafter, for the sake of simplicity, the simple fixing means will be described as the fixing means.

In the surface fastener, the back surface of the surface fastener is fixed to the laminate with an adhesive or an adhesive, and in the tape-like member to which the button-shaped fastener or the magnet is attached, the tape-like member is laminated with an adhesive or an adhesive. Can be fixed to. It is desirable that the fixing means be provided evenly over the entire area from the upper end to the lower end of the short side, but there is no particular problem as long as it can be supported sufficiently stably even if it is supported separately in the upper part, the middle part, and the lower part. ..

Further, the thickness of the resin foam can be increased by forming a laminate of the resin foam in which another sheet-like resin foam is laminated on the other surface of the resin foam of the cushion material. Therefore, the cushioning property of the laminated body and the moisture-proof property of the cushioning material can be improved. Furthermore, the assembly independence when used as a partition can be enhanced.

At this time, the other sheet-shaped resin foam has a hardness equal to or harder than that of the resin foam having a wavy uneven structure, thereby preventing excessive sinking of the cushion material while maintaining the cushioning property. can do.

In this way, by forming the cushion material into a laminated body, it can be used as a disaster mat material that can be used as a partition side wall of an evacuation shelter or a bed in the event of a disaster, and normally as a wall panel material for shock absorption. Can be used. Since the same cushion material can be used for various purposes in this way, it is extremely convenient.

As the laminate, a resin foam having a foaming ratio of 20 to 40 times or less is used, and the height (Hv) from the flat surface of the sheet-shaped foam on the back surface of the laminate to the valley portion of the laminate. ), The ratio R of the height from the flat surface of the sheet-like foam on the back surface of the laminated body to the center line height (Hc) of the corrugated uneven structure surface is 50% or more. By doing so, the center of gravity of the laminated body can be positioned within the flat portion of the laminated body, and the laminated body can be easily assembled without causing slight bending or bending between the connecting portions during assembly. Therefore, it is possible to easily assemble the partition for the shelter compartment from the laminated body. The laminate of the second invention is cut in a straight line by connecting the inflection point positions of the profile processed surface of the laminate so that the cross-sectional area of the substantially parallel portion occupying the end surface of the laminate is maximized. It is desirable to have.

As described above, according to the laminate of the second invention, it is possible to obtain a disaster mat material and a shock absorbing wall panel material that can be used as a partition or a bed for a shelter having excellent design and assembly independence. Can be done.

Such a cushion material or laminate can be used as a disaster mat material that can be used as a bed. Further, the cushion material can also be used as a partition material or a wall panel material for shock absorption, depending on the case. In addition, when used in evacuation shelters, evacuation mat materials, partition materials, or shock absorbing wall panel materials that can be used as beds with deodorant, antibacterial, and antiviral effects on cushioning materials or laminates. It can be used for both, and it is possible to improve the sanitary condition of the evacuation center.

In the third invention, the pressing force of the upper and lower rolls immediately after passing through the profile roll does not completely recover the elasticity of the sheet-shaped resin foam having a predetermined thickness facing the colored adhesive layer or the fusional layer. A state in which the adhesive layer or the fusion layer is curved by slicing and cutting in the horizontal direction perpendicular to the thickness direction of the resin foam at a position including the adhesive layer or the fusion layer. The resin foam cut and separated so as to cross the adhesive layer or the fusional layer curved in the above is elastically recovered, and the adhesive layer or the fusional layer is flat with a predetermined length and a predetermined shape. By being formed in a planar shape, a large number of cyclic rings are formed as exposed portions of the flat surface at a predetermined height portion between the peaks and valleys of the surface of the corrugated uneven structure of the resin foam. This is a method for manufacturing a cushioning material, characterized in that a linear pattern is formed as a two-dimensional pattern on the same plane. In this case, the sheet-shaped resin foam facing the adhesive layer or the fusion-bonded layer may be an uncolored white resin foam.

By coloring at least one of the colored adhesive layer or the sheet-shaped resin foam having a predetermined thickness facing each other across the fusion layer, or by making both resin foams different colors. In addition to a large number of annular patterns formed in a two-dimensional coplanar shape with the colored adhesive layer or the fusion layer as an interface, the resin foam is combined with the mountain side of the corrugated uneven structure. A three-dimensional three-dimensional pattern may be formed in which the valley side is colored in a different color.

Whether to shift the formation position of the adhesive layer or the fusion layer of the resin foam so as not to exceed the width of the curvature formed on the adhesion layer or the fusion layer of the resin foam by the upper and lower rolls. Alternatively, by changing the height at which the slicing process is performed on the outlet side of the roll, the formation positions of the peaks and valleys of the corrugated uneven structure are adjusted, and the size of the linear pattern is adjusted. Then, it may be possible to obtain two cushioning materials having different sizes of the linear pattern. In this way, by slicing a position offset from a position corresponding to the center height between the upper and lower rolls, cushioning materials having different sizes of linear patterns can be obtained. Further, by similarly offsetting the slice position for the laminated body described later, it is possible to obtain two laminated bodies having different linear pattern sizes.

According to the third invention, it is possible to easily manufacture a cushion material having a large number of linear patterns having excellent design. Further, by using resin foams of different colors for the sheet-shaped resin foams, it is possible to convert from a linear pattern to a three-dimensional three-dimensional pattern.

Further, the position of forming the adhesive layer or the fusion layer of the material before the profile roll processing is shifted or the roll is formed so as not to exceed the width of the curvature formed on the adhesion layer or the fusion layer of the resin foam by the profile roll. By adjusting the height at which the slicing process is performed on the outlet side of the resin foam, the size of the linear pattern or the three-dimensional pattern formed on the resin foam can be adjusted. Further, by laminating the sheet-shaped resin foam on the flat surface of the back surface of the cushion material, not only the design property but also the assembly independence of the laminated body can be improved. Further, it is possible to improve the basic performance as a foam material such as heat insulation, shock absorption and moisture resistance.

As described above, by slicing, for example, the pattern on the mountain side formed by the linear pattern or the resin foam can be made smaller, or conversely, the mountain portion formed by the linear pattern or the resin foam. It is possible to form a large pattern of. This makes it possible to emphasize the mountain side more and the valley side more.

Further, the fourth invention is a sheet-like resin foam having a predetermined thickness facing the colored adhesive layer or the fusion-bonded layer, which is opposite to the adhesive layer or the fusion-bonded layer. Using four layers of resin foam to which another sheet-like resin foam layer is further adhered or fused to the outside of the resin foam of the above, among the four layers while maintaining the curved shape by profile roll processing. By performing slicing in the horizontal direction perpendicular to the thickness direction of the resin foam so as to cross the adhesive layer between the two layers of the resin foam layer of the inner layer, only the two layers of the inner layer resin layer are mountainous. It is a method for producing a laminated body, characterized in that a valley portion is formed and a resin foam of an inner layer resin layer and an outer layer resin layer is integrated.

Further, a laminated body can be obtained by slicing the four-layer sheet-shaped resin foam at the time of profile roll processing under predetermined conditions. By doing so, it is possible to obtain the laminate of the present application without sticking the sheet-like foam on the back surface of the cushion material.

According to the fourth invention, it is possible to easily manufacture a cushion material having excellent design and a laminate in which a sheet-shaped resin foam is fused or adhered to a flat surface of the cushion material.

A fifth aspect of the present invention is a method of using a cushioning material in which flat surfaces of the cushioning material are opposed to each other according to the first aspect of the invention, and the surface of the cushioning material having a wavy uneven structure is directed toward an outer surface. As a stilt with design and shock absorption, a large number of the linear patterns are formed side by side on the outer surface, which is used by standing upright by stacking flat surfaces facing each other and supporting them with a support member. How to use.

More specifically, the surfaces of the corrugated uneven structure of the pair of cushioning materials are directed outward in opposite directions, and the flat surfaces that are the back surfaces of the corrugated uneven structure are brought into contact with each other. The mountain portion formed on one of the cushion materials and the valley portion formed on the other cushion material are arranged at a predetermined distance from each other, and the valley portion formed on one of the cushion materials. A cushioning material characterized in that the surfaces of the pair of cushioning materials have a wavy shape substantially parallel to each other by arranging the mountain portions formed on the other cushioning material at a predetermined distance. Can be used as. By directing the wavy concave-convex structure outward, both sides of the laminated body can be made excellent in design, so that it can be optimally used for a tsuitate.

A fifth aspect of the present invention is a method of using a cushioning material in which two cushioning materials according to the first invention are stacked and a cushioning material imparted with functionality is laminated, and the wave of the cushioning material is used. A method of using the cushion material may be characterized in that the linear patterns are formed side by side on substantially the same plane by overlapping the forming surfaces of the uneven structure of the shape with each other. It is desirable that the linear patterns are formed side by side on substantially the same plane, and the occupancy rate of the total area of the adhesive layer with respect to the plane is 80% or more.

More specifically, the mountain portions formed on one cushion material and the valley portions formed on the other cushion material face each other with the surfaces of the wavy uneven structure of the pair of cushion materials facing each other. A line in which the valley portion formed on one cushion material and the mountain portion formed on the other cushion material are arranged so as to face each other and are arranged between the respective peaks and valleys. It is also possible to arrange the bonded surfaces, which are shaped like a pattern, adjacent to each other on substantially the same plane. In the usage method in which the corrugated uneven structure of the cushion material is used by arranging the cushion materials facing each other inward, the outer surface of the stacked cushion materials is made into a flat shape, and many islands are formed in the stacked surface. Functionality can be imparted to the adhesive layer formed by exposure.

The laminate may be used as a partition material or a shock absorbing wall panel material. When the corrugated concavo-convex structure is directed outward, the design is excellent, and when the corrugated concavo-convex structure is opposed to the inside, the surface is flat and it is possible to impart functionality. The adhesive surfaces arranged adjacent to each other on substantially the same plane may form a plane having functionality.

According to the present invention, by combining the corrugated shapes of two cushioning materials, it can be used as a partition material or a wall panel material inside a public facility. At this time, since the adhesive surfaces of the two cushioning materials can be arranged in a substantially flat shape at predetermined positions in a wavy shape, for example, if the adhesive surfaces are provided with vibration damping properties and flame retardancy, the resin In addition to the cushioning property and sound insulation property of the foam, the vibration damping property and flame retardancy of the adhesive layer can be superimposed.

Further, the adhesive surface of the overlapped cushioning materials has a continuous curved surface shape folded by a profile roll before slicing, but after slicing into two cushioning materials, the cushioning material has a flat shape. As a result, the sliced surface becomes a wavy uneven structure surface, and the area of the cushion material wavy uneven structure surface increases apparently. Therefore, the cushion material with respect to the total area of the two cushion materials in the plane direction. The total area of the adhesive surfaces formed at the predetermined heights of the sliced surfaces of the above is not 100%.

That is, in a plan view, it is desirable that the apparent total occupancy ratio of the adhesive surfaces of the two cushioning materials arranged adjacent to each other on substantially the same plane is high with respect to the total area. If the total area occupied by the total area including the adhesive surface with respect to the total area of the adhesive surfaces formed by superimposing the cushioning materials is 80% or more, when the adhesive surface is provided with functionality, It becomes possible to exert its functionality more reliably. Further, it is more desirable if the total apparent occupancy of the adhesive surface is 90% or more.

Further, functionality can be imparted to the adhesive surfaces arranged adjacent to each other on substantially the same plane. For example, vibration damping property, flame retardancy, design property and the like can be imparted. In this way, when using one sheet, it is possible to improve the decorativeness by utilizing the design, and when using two sheets, the functionality and assembly independence can be improved, but with two sheets. It is also possible to make a laminated body that emphasizes design even when it is used.

Such a laminate can be used as both a partition material and a wall panel material. At this time, by combining the corrugated uneven structures of the cushion materials in opposite directions or in opposition to each other, the assembly independence can be improved when used as a partition material for a partition material or a wall surface panel material. Can be improved.

According to the fifth invention, by combining the corrugated shapes of the two cushion materials, it can be used as a partition material or a wall panel material inside a public facility. Further, when the surface of the cushion material having a wavy uneven structure is used toward the outer surface, the design can be improved. Further, when the corrugated concavo-convex structures are used facing each other, the two cushioning materials can arrange the adhesive surfaces in a substantially flat shape at a predetermined position of the corrugated surface, so that the adhesive surface has functionality. If it is given, it becomes possible to express the functionality.

Specifically, if the adhesive layer is provided with quietness and vibration damping properties, the quietness and vibration damping properties of the adhesive layer can be superimposed in addition to the cushioning and vibration damping properties of the resin foam. It will be possible. Here, as the function to be imparted to the adhesive layer or the fusional layer, since it is premised that the two sheets are used in combination with each other, the effect can be obtained even if it is not the outermost surface of the resin foam. Physical functions that are easy to exert are desirable.

The sixth invention is a structure of a shelter section using the laminate according to the second invention, and the laminate has a substantially rectangular shape having a long side twice the short side and the substantially rectangular shape. Two of the laminates are arranged on the floor surface as a disaster mat that can be used as a bed so as to form a substantially square section by contacting the long sides of the laminates with each other, and the laminates are further arranged in the short side direction. In the erected state, the long side of the laminated body is used as a contact surface with the floor surface so as to surround the outer periphery of the disaster mat as the substantially square floor material, and the back surface of the erected laminated body. It is a connection structure in which the fixing means fixed to the short side end surface of the flat surface and the flat portion of the short side end surface are repeatedly connected and fixed abutting or fitting at substantially right angles to each other. It is a connection structure of a shelter section, which includes at least a section in which a U-shaped side wall having one side of a substantially square opening is formed.

The connection fixing of the laminate is a button fixed to a tape-shaped member attached to the surface of the laminate as a fixing means attached to the surface of the laminate, which can be easily connected at the time of assembly and separated at the time of disassembly. It may be a connection structure of a shelter section which is connected and fixed by any of a shape fastener, a magnet, or a hook-and-loop fastener on which a large number of microprojections are formed. At this time, in the surface fastener, the back surface of the surface fastener is fixed to the laminate with an adhesive or an adhesive, and in the tape-like member to which the button-shaped fastener or the magnet is attached, the tape-like member is laminated with an adhesive or an adhesive. Can be fixed to. Since this laminate is as light as 5 kg or less, usually 2 kg or less, it can be fixed by a simple fixing means.

In the connection structure of the evacuation center section using the laminate, the inflection point position of the profiled surface of the laminate is set so that the cross-sectional area of the substantially parallel portion of the cut surface of the end surface of the laminate is maximized. By tying and cutting in a straight line, the fixing means may be attached to the flat portion of the short side end face formed by cutting in a substantially rectangular shape.
Here, the distance from the adjacent mountain top to the mountain top of the curve that alternately passes the profiled surface of the laminated body through the mountain tops and the valley tops that are arranged adjacent to each other is defined as one pitch. Then, a position deviated by (1/4) pitch from the top of the mountain or the bottom of the valley, that is, connecting a plurality of inflection point positions between the top of the mountain and the bottom of the valley or between the bottom of the valley and the top of the mountain. By cutting in a substantially straight line, it is possible to obtain a substantially rectangular cut surface having the maximum cross-sectional area of the parallel portion occupying the cut surface of the end surface of the laminated body.

Since the peaks and valleys in the curve that alternately passes through the peaks and valleys that are arranged adjacent to each other are staggered so as to be orthogonal to each other, the mountain and valleys are arranged in a staggered manner. The periodic structure will have a similar periodic structure in the direction orthogonal to the curve. Therefore, in the direction orthogonal to the above curve, the position deviated by (1/4) pitch from the top of the mountain or the bottom of the valley, that is, the middle from the top of the mountain to the bottom of the valley or from the bottom of the valley to the top of the mountain. By cutting in a substantially straight line so as to connect the positions of the inflection points in the middle, it is possible to obtain a cut surface having the maximum cross-sectional area of the parallel portion occupying the cut surface of the end surface of the laminated body. As a result, it is possible to obtain a substantially rectangular cut surface having a maximum cross-sectional area of a substantially parallel portion of the cut surface of the end surface of the laminated body.

Comparing the end portion of the flat surface to be connected and fixed by the fixing means in the laminated body and the cushion material and the side end surface, since the side end surface includes the profile processed surface, the flat portion to which the fixing means is bonded depends on the cutting position. The area is different. Therefore, if the cross section having the largest parallel portion area on the side end surface is selected and that portion is used as the cutting portion, the area to which the fixing means such as the surface fastener is attached can be maximized.

In the connection structure of the evacuation shelter section, a cushioning material may be used instead of the laminated body.

(First Embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1A is a front perspective view of the cushion material 1, FIG. 1B is a back perspective view of the cushion material, and FIG. 2 is a schematic plan view of the cushion material 1.

The cushion material 1 is formed of a polyolefin resin foam. A mountain portion 5 and a valley portion 7 are formed on one surface (surface 3) of the cushion material 1. The peaks 5 and valleys 7 are periodically arranged vertically and horizontally alternately. That is, the surface 3 of the cushion material 1 has a wavy uneven structure, the peaks 5 are formed at predetermined intervals, valleys 7 are formed between the peaks 5, and the

peaks

5 and 7 are formed. However, each is provided in a so-called staggered arrangement. Therefore, a valley portion 7 is formed in a portion vertically and horizontally adjacent to the mountain portion 5, and a mountain portion 5 is formed in a portion vertically and horizontally adjacent to the valley portion 7.

Further, the mountain portion 5 and the valley portion 7 are not formed on the other surface (back surface 9) of the cushion material 1 and are flat. That is, the cushion material 1 has peaks 5 and valleys 7 formed only on the surface 3.

FIG. 3 is a cross-sectional view taken along the line AA of FIG. As shown in the figure, the mountain portion 5 is a thick portion, and the valley portion 7 is a thin portion. It should be noted that a ridge having a thickness substantially intermediate between the thicknesses of the mountain portions 5 and the valley portions 7 is formed between the mountain portions 5 adjacent to each other in the diagonal direction (between the valley portions 7 adjacent to each other in the diagonal direction). To. That is, the wavy uneven structure on the surface of the cushion material 1 is formed smoothly and continuously in this way.

Further, the cushion material 1 includes an adhesive layer 17 formed on the laminated surface of the resin foams 15a and 15b by laminating the resin foam 15a forming the peak portion 5 and the resin foam 15b forming the valley portion 7. .. In the following description, an example in which the adhesive layer 17 is formed on the laminated surface of the resin foams 15a and 15b will be described, but a fusion layer may be used instead of the adhesive layer 17. When the adhesive layer is not colored, it is recognized as white, which is substantially the same color as the resin foams 15a and 15b, like the fusion layer. Since the cross section of the cushion material is usually invisible, the colored adhesive layer or fusion layer is observed as a large number of annular linear patterns as described later.

When the adhesive layer 17 is formed by an adhesive on the laminated surface of the resin foams 15a and 15b, at least one kind of flexible resin such as urethane resin, vinyl acetate emulsion, acrylic resin, silicone resin and modified silicone resin is used. An adhesive contained as a main component can be used. In particular, by using an adhesive containing at least one flexible resin selected from the group consisting of urethane resin, silicone resin and modified silicone resin as a main component, vibration damping property is imparted to the cushion material 1. Can be done. Further, an adhesive containing an acrylic acid ester-based polymer, a halogen-containing phosphoric acid ester, and an inorganic flame retardant as essential components can also be used in the adhesive layer 17. By doing so, it is possible to impart flame retardancy and vibration damping property to the cushion material 1. As described above, the corrugated uneven structure of the cushion material 1 may be one in which the adhesive layer 17 (or the fusion layer) is provided with functionality.

An adhesive layer 17 formed substantially parallel to the back surface 9 is exposed at a predetermined height portion of the front surface 3 of the wavy uneven structure. The adhesive layer 17 forms a large number of annular linear patterns 11 at predetermined intervals from each other in a plan view. The linear pattern 11 partitions the peaks 5 and valleys 7 having a wavy uneven structure, and is formed in an annular shape at a predetermined height between the peaks 5 and the valleys 7 so as to surround the respective peaks 5. , Excellent in design and moisture resistance. That is, the surface 3 of the cushion material 1 has a mountain portion 5 formed by the resin foam 15a above the linear pattern 11, a linear pattern forming portion 13 on which the linear pattern 11 is formed, and a linear pattern 11. It is partitioned into three portions with a valley portion 7 formed by the lower resin foam 15b. The valley portions 7 are continuously integrated with each other in the adjacent valley portions 7.

The resin foams 15a and 15b are preferably at least one of polyethylene, low-density polyethylene, high-density polyethylene, ethylene-vinyl acetate copolymer, or polypropylene resin, or a mixture of two or more thereof. At this time, it is desirable that the foaming ratios of the resin foams 15a and 15b are 20 to 40 times. In particular, it is desirable that the resin foams 15a and 15b are polyethylene resins. It is desirable that this polyethylene resin has a compression set of 3.0% to 7.4% and a compressive stress of 34 kPa to 56 kPa at 25% compression at a test temperature of 25 ° C. based on JIS K6767.

The compressive stress of the resin foams 15a and 15b is measured by the compressive stress test by the compressive stress strain ISO3386-1 in JIS K6767: 1999. At this time, the moving speed of the compression plate of the testing machine is about 50% of the material thickness per minute, the test temperature is 25 ° C., and the compressive stress at the time of 25% compression of the material thickness is measured.

The compression set of the resin foams 15a and 15b is measured by a test according to ISO1856 in JIS K6767: 1999. A permanent compression strain can be obtained by compressing the test piece into a state of being distorted by 25%, leaving it at a temperature of 23 ° C. ± 2 ° C. for 22 hours, and measuring the thickness 24 hours after the completion of compression.

In this way, by using the resin foams 15a and 15b as polyethylene resin, the hygroscopicity (water absorption rate) of the cushion material 1 can be lowered. The water absorption rates of the resin foams 15a and 15b are measured by the ISO2896 B method. In the case of a sample in which a skin layer is formed on both sides or one side, the water absorption rate can be calculated by the following formula.
Qs = (W1-W2) / A
Qs: Water absorption rate (g / cm ² )
W1: Mass (g) of the test piece immediately after cutting to 100 mm × 100 mm
W2: Mass (g) of test piece after drying at 60 ° C. for 24 hours
A: Area of test piece (cm ² )
In the present invention, the water absorption rate of polyethylene is preferably 0.03 mg / cm ² or less.

Further, it is desirable that the tensile strengths of the resin foams 15a and 15b in the MD direction are 273 kPa to 495 kPa and the tensile strength in the TD direction is 201 kPa to 333 kPa. Further, it is desirable that the elongation values of the resin foams 15a and 15b in the MD direction are 92% to 100% and the elongation values in the TD direction are 114% to 120%. The tensile strength and elongation value are obtained from the tensile strength and elongation value at break of the test conducted at a test speed of 500 mm / min according to ISO1798.

Further, in the resin foams 15a and 15b, any one of silica, zirconium phosphate, zeolite, zinc sulfate, or zirconium sulfate is added as a deodorant to 100 parts by mass of the resin component from 0.5 parts by mass to 5 parts by mass. It may be included in the range of parts by mass. In this way, a deodorant can be contained to impart a deodorizing function.

Next, the manufacturing method of the cushion material 1 will be described. First, the resin foams 15a and 15b are produced. FIG. 4 is a diagram showing a resin foam manufacturing apparatus 20. The resin foam manufacturing apparatus 20 is mainly composed of an extrusion machine 21, a roll forming machine 23, a heating furnace 25, a winding machine 27, and the like.

For example, a master batch containing a raw material resin (for example, polyethylene resin), a pigment, a chemical foaming agent, and a cross-linking agent is put into an extruder 21 and extruded into a sheet shape having a predetermined width. Next, the material thickness and width are adjusted by passing through the roll forming machine 23. Further, in the heating furnace 25, the inside of the furnace is set so that the temperature gradually rises toward the inner side of the furnace within a predetermined temperature (for example, 190 ° C. to 240 ° C.) on a wire mesh conveyor. To transport to. In the heating furnace 25, the cross-linking agent is first thermally decomposed, the polyethylene resin is cross-linked, and then the chemical foaming agent is thermally decomposed to obtain a predetermined sheet thickness (preferably 15 mm or more) at a predetermined foaming ratio (for example, 30 times). 20 mm) resin foams 15a and 15b can be obtained.

In the production of the resin foams 15a and 15b, DCP (dicumyl peroxide) can be used as a cross-linking agent. At this time, ADCA can be used as a chemical foaming agent without using a bubble nucleating agent. In general, as the nucleating agent, carbon dioxide gas may be used as a physical nucleating material such as mono-Na citrate, a surfactant, and silicone oil. When the fused layer is discolored yellow, it is desirable to use ADCA as the chemical foaming agent.

Next, the obtained resin foams 15a and 15b are laminated by fusion or adhesion. The resin foams 15a and 15b to be adhered or fused may have the same thickness or different thicknesses.

For example, an adhesive is applied to the respective surfaces of the resin foams 15a and 15b, and the opposite surface to which the adhesive is not applied is pressed with a press, or one of the resin foams 15a and 15b is foamed. By passing a roll coated with an adhesive, the adhesive is applied to the resin foam, and the surface to which the adhesive is applied is used as the bonding surface, and the other resin foam is overlapped. Then, the two resin foams can be adhered by passing through different rolls. At this time, the adhesive can be colored with an organic dye, dye, pigment or the like, or at least one adhesive surface can be colored with an organic dye, dye, pigment or the like. When the resin foams 15a and 15b are heat-sealed, they are heated to around 180 ° C. for about 10 to 20 seconds with a far-infrared heater, and then passed through a roll to fuse the heat-sealing. Can be made to. Here, the fused surface can be colored with an organic dye, a dye, a pigment, or the like, as in the case of bonding. Further, since the resin is remelted and recrystallized when the surface of the resin foam and the fused portion are fused, the change in the crystallized state and the molecular weight at that time and the residual of ADCA are likely to remain on the surface. By superimposing the effects and the like, the fused portion can be colored yellow.

Next, profile processing is performed on a sheet-shaped resin foam (hereinafter referred to as a laminated resin foam) having a predetermined thickness facing the adhesive layer. FIG. 5A is a front view showing rolls 31a and 31b which are profile rolls used for profile processing of the cushion material 1, and FIG. 5B is a side view showing rolls 31a and 31b. Since the roll 31b has the same configuration as the roll 31a, the description thereof will be omitted.

The roll 31a has a plurality of convex portions 33 formed on the surface of a cylindrical roll. The convex portions 33 are arranged in a staggered pattern on the surface of the roll 31a. That is, the convex portions 33 are formed at predetermined intervals (predetermined pitch) in the longitudinal direction of the roll 31a, and the convex portions 33 adjacent to each other in the circumferential direction are formed at positions shifted by half a pitch with respect to the above-mentioned installation pitch. The portion surrounded by the convex portion 33 is the concave portion 35. The concave portion 35 is slightly larger than the convex portion 33, and the convex portion 33 and the concave portion 35 facing each other can mesh with each other.

The rolls 31a and 31b are arranged at predetermined intervals so as to face each other. The spacing between the rolls 31a and 31b can be adjusted. At this time, the rolls 31a and 31b are arranged at circumferential positions so that the positions of the convex portions 33 and the concave portions 35 of the rolls 31a and 31b facing each other do not match.

That is, in a state where the rolls 31a and 31b are installed facing each other, the convex portion 33 of the upper roll 31a is located at the lowermost end (the side facing the roll 31b) at a certain circumferential cross-sectional position (for example, FIG. 5B). At this time, the recess 35 is located at the uppermost end (roll 31a side) of the lower roll 31b. Further, the rotations of each other are controlled and synchronized so that such positions are alternately repeated. The convex portions 33 and the concave portions 35 in the longitudinal direction of the rolls 31a and 31b are also installed so as to be staggered so as not to coincide with each other.

FIG. 6A is a diagram showing a state in which the cushion material 1 is manufactured using the rolls 31a and 31b. As described above, the rolls 31a and 31b are installed at predetermined intervals. The rolls 31a and 31b rotate in opposite directions (in the direction of arrow D in the figure), and bite the laminated resin foam 39 from one side. The laminated resin foam 39 is obtained by laminating the above-mentioned resin foams 15a and 15b and adhering or fusing them together.

Here, the laminated resin foam 39 is a resin foam 15a and 15b having the same foaming ratio and sheet thickness, laminated and bonded or fused as described above. The laminated resin foam 39 is bitten by the rolls 31a and 31b and sequentially sent backward (in the direction of arrow E in the figure). A cutting blade 37 is provided on the slightly rear side of the biting portion of the rolls 31a and 31b. The cutting blade 37 cuts the laminated resin foam 39 perpendicularly in the thickness direction, and has a width at least equal to or larger than the width of the laminated resin foam 39. The laminated resin foam 39 is sent to the rear of the rolls 31a and 31b while being crushed (deformed) by the rolls 31a and 31b, and is perpendicular to the thickness direction by the cutting blade 37 in a state of being deformed by the rolls 31a and 31b. Will be disconnected.

FIG. 6B is an enlarged view of part C of FIG. 6A. The laminated resin foam 39 is elastically deformed by the convex portions 33 and the concave portions 35 of the rolls 31a and 31b. As described above, the rolls 31a and 31b rotate so that the convex portion 33 (concave portion 35) of the roll 31a and the concave portion 35 (convex portion 33) of the roll 31b are in alternate positions. Therefore, the laminated resin foam 39 has a corrugated shape so as to sew between the convex portion 33 and the concave portion 35 of the upper roll 31a and the convex portion 33 and the concave portion 35 of the lower roll 31b.

The cutting blade 37 cuts the laminated resin foam 39 in a state where the laminated resin foam 39 has a wavy shape. Here, the cutting blade 37 is installed at substantially the center of the laminated resin foam 39 in the thickness direction (intermediate between the rolls 31a and 31b). However, at the portion where the cutting is actually performed, the laminated resin foam 39 is deformed into a corrugated shape. Therefore, the center of the laminated resin foam 39 in the thickness direction is not cut straight, but the laminated resin foam 39 is cut in a corrugated manner with respect to the thickness direction.

Here, the laminated resin foam 39 has an adhesive layer 17 formed inside. Therefore, when the laminated resin foam 39 is deformed into a corrugated shape, the adhesive layer 17 is in a state of being repeatedly deformed into a corrugated shape up and down while forming the center line of the laminated resin foam 39. The cutting blade 37 cuts the laminated resin foam 39 so as to cross the corrugated adhesive layer 17.

The laminated resin foam 39 after cutting is sent to the rear of the rolls 31a and 31b while the deformation caused by the rolls 31a and 31b (convex portion 33 and concave portion 35) returns to the original state. At this time, the portion cut by the cutting blade 37 returns to the waveform. Therefore, peaks 5 and valleys 7 are formed on the cut surface of the laminated resin foam 39. That is, the portion deformed in the concave portion 35 of the roll centering on the cutting blade 37 becomes the peak portion 5 of the cushion material 1, and the portion crushed by the convex portion 33 of the roll becomes the valley portion 7 of the cushion material 1. .. That is, the contact surface with the rolls 31a and 31b has a flat shape, and conversely, the cut surface is a wave in which peaks and valleys are alternately arranged vertically and horizontally according to the uneven pitch of the rolls 31a and 31b. An uneven structure of shape can be obtained.

As described above, in the present embodiment, the laminated resin foam 39 immediately after passing through the rolls 31a and 31b, which are the profile rolls, has the adhesive layer 17 (the adhesive layer 17 () before the pressing force by the upper and lower rolls 31a and 31b is completely elastically recovered. Alternatively, it is sliced and cut at a position including a fused layer (the same applies hereinafter). In this way, since the adhesive layer 17 is cut so as to cross the curved adhesive layer 17 in a curved state, the cut and separated laminated resin foam 39 elastically recovers, and the adhesive layer 17 has a predetermined length and a predetermined length. When the laminated resin foam 39 is formed on a flat surface in shape, the adhesive layer 17 is exposed at a predetermined height on the surface between the peaks 5 and the valleys 7 of the corrugated uneven structure of the laminated resin foam 39, and the flat surface. As the exposed portion of the roll, a periodic linear pattern 11 is formed in a staggered manner corresponding to the longitudinal direction and the width direction of the roll. As described above, a pair of cushioning materials 1 having a wavy uneven structure formed by profile processing are formed.

The cushion material 1 thus obtained is a disaster mat material that can be used as a bed, for example, with the surface (front surface 3) for forming a wavy uneven structure as the upper surface and the other surface (back surface 9) as the lower surface. It can be used as.

As described above, according to the present embodiment, it is possible to obtain the cushion material 1 having a wavy uneven structure on the front surface 3 and a flat back surface 9. At this time, since a large number of annular linear patterns 11 are formed in a staggered pattern at a predetermined height of the mountain portion 5 having a wavy uneven structure, the design is excellent. Further, since such a cushion material 1 can be obtained by profile-processing the laminated resin foam 39, the manufacturability is good. Although details will be described later, the linear pattern 11 (by making at least one of the laminated resin foams 15a and 15b colored, or by making both resin foams 15a and 15b different colors, With the position of the adhesive layer 17) as the interface, the mountain portion 5 side and the valley portion 7 side (including the bottom portion) of the wavy uneven structure are colored in different colors with respect to the linear pattern forming portion 13. 3D pattern can be formed.

In the illustrated example, the cutting blade 37 is installed at substantially the center of the rolls 31a and 31b (approximately the center of the laminated resin foam 39 to be cut in the thickness direction), but the present invention is not limited to this. For example, within the height range of the corrugated peaks 5 and valleys 7 of the adhesive layer 17 in the state of being bitten by the rolls 31a and 31b (adhesive layer or fusion layer of the laminated resin foam 39). The cutting position may be moved in a predetermined amount in the vertical direction so as not to exceed the width (height) of the curvature formed in the roll, and the height at which the slicing process is performed on the outlet side of the roll may be adjusted. Alternatively, by increasing the thickness of one of the resin foams 15a and 15b while keeping the cutting blade 37 installed substantially in the center of the rolls 31a and 31b, the position where the adhesive layer 17 of the laminated resin foam 39 is formed can be determined. It may be shifted from the center of the thickness.

This makes it possible to change the area ratio of the peaks 5 and valleys 7 of the cut wavy uneven structure. As a result, the size of the linear pattern 11 or the three-dimensional pattern formed by the adhesive layer 17 can be adjusted. In this way, by changing the area ratio of the mountain portion 5 formed by the resin foam 15b and the area ratio of the valley portion 7 formed by the resin foam 15a, at least one of the resin foam 15a and the resin foam 15b is colored. It is possible to greatly change the texture and design of a three-dimensional design. In this way, the formation positions of the peaks 5 and the valleys 7 of the wavy uneven structure are adjusted to adjust the sizes of a large number of annular linear patterns 11, and the sizes of the linear patterns 11 are different. It is also possible to obtain two cushioning materials 1.

Further, if the resin foams 15a and 15b are made of polyethylene, the hygroscopicity is low, so that the moistureproof property of a mat or the like using the cushion material 1 can be enhanced. Therefore, when the cushion material 1 is used as a mat in the event of a disaster, the cushion material 1 does not absorb moisture and is made of a profiled foam material, so that it can also be used as a bed for a comfortable sleep. It can provide an environment and a living environment.

Further, other functions can be imparted to the adhesive layer 17. For example, it is possible to impart vibration damping and flame retardant functions. Further, the resin foams 15a and 15b may be provided with a deodorizing function.

In addition to the above, the laminate is formed by laminating flat resin foams 15c and 15d after roll molding on the cushion material 1 formed by slicing two layers of resin foam as described later. You may.

(Second Embodiment)
Next, the second embodiment will be described. FIG. 7 is a cross-sectional view showing a laminated body 1a in which a sheet-shaped resin foam is fused or adhered to the back surface of a cushion material. In the following description, the same configurations as those of the cushion material 1 are designated by the same reference numerals as those in FIGS. 1A to 6B, and duplicate description will be omitted.

The laminated body 1a has substantially the same structure as the cushion material 1, but differs in that the resin foam 15c is laminated by fusing or adhering the sheet-shaped resin foam 15c to the back surface of the cushion material 1. In the laminated body 1a, another sheet-shaped resin foam 15c is laminated and adhered or fused to the other flat surface of the back surface of the corrugated uneven structure forming surface of the cushion material 1. Although another sheet-shaped resin foam may be laminated on the back surface 9 of the laminated body 1a and bonded or fused, the sheet-shaped resin foam is usually fused or bonded. Is enough.

At this time, another sheet-shaped resin foam 15c for fusing or adhering the sheet-shaped resin foam to the back surface of the cushion material has a hardness equal to or harder than that of the resin foams 15a and 15b having a wavy uneven structure. It is desirable to have. Here, by using the sheet-shaped resin foam 15c to be attached to the back surface of the cushion material as a resin having a lower foaming ratio than the resin foams 15a and 15b, assembly independence when used for a partition for partitioning described later Can be improved.

The method for producing the laminated body 1a is not particularly limited, but for example, the four-layer laminated resin foam may be cut using the rolls 31a and 31b shown in FIGS. 5A and 5B. First, another sheet-shaped resin foam layer is formed on the outside of each of the sheet-shaped resin foams having a predetermined thickness facing each other with the adhesive layer or the fusion-bonded layer on the opposite side of the adhesive layer or the fusion-bonded layer. Form a four-layer laminated resin foam that is further adhered or fused. In this case, the roll spacing between the rolls 31a and 31b is adjusted, and slicing is performed between the intermediate second and third layers excluding the upper and lower surface layers (first and fourth layers). The same processing as that of the two-layer laminated resin foam 39 can be performed. For this reason, the flat resin foams 15c or 15c and 15d are laminated on the flat back surface of the resin foam 15b having a wavy uneven structure on the surface on which the periodic linear pattern 11 is formed. The bodies 1a and 1b can be obtained.

In this way, slicing is performed between the second and third layers in the middle while maintaining the curved shape by profile roll processing inside the resin foam layer forming the two inner layers of the four layers. As a result, it is possible to manufacture a laminate in which a flat sheet-shaped foamed resin layer is integrated with the outer layer of the profile-processed inner layer resin layer.

According to the second embodiment, the effect of enhancing the design can be obtained as in the first embodiment. Further, by laminating the resin foam 15c or the like, a thicker laminated body 1a and 1b can be obtained, so that a larger cushioning property can be obtained. Further, since the thickness is increased, the assembly independence of the laminated body can be enhanced in addition to the moisture resistance.

At this time, the laminated bodies 1a and 1b can impart the heat insulating property, cushioning property and moisture proofing property required for the partition members of the evacuation center, and also have a periodic pattern of a corrugated uneven structure on the surface, so that the design is provided. Although it is excellent in properties, the thickness is increased by the sheet-shaped resin foams 15c and 15d, so that the assembly independence is also improved. Therefore, as will be described later, when it is used as a partition wall for a partition in an evacuation shelter, it can be easily made independent. Further, the laminates 1a and 1b are lightweight, and at the same time, the side surfaces of the ends of the laminates 1a and 1b and the flat portions of the laminates 1a and 1b can be fixed by, for example, a hook-and-loop fastener, so that tools and assembly parts can be used. It is possible to easily form a partition wall for a partition of an evacuation center without using it. Therefore, it can be suitably used as a partition member of an evacuation shelter.

Moreover, the design can be further improved by fusing the corrugated uneven structure of the laminated bodies 1a and 1b or changing the coloring of the foams above and below the adhesive surface. For this reason, when used as a partition member or floor mat for the partition wall of a shelter, the floor mat can also be used as a bed because it has functionality such as heat insulation, cushioning, and moisture resistance. Not only does it keep the living environment in the shelter of the victims comfortable, but it also has the effect of keeping the victims feeling bright.

Further, when the laminated bodies 1a and 1b are used as a mat by making the sheet-shaped resin foam 15c or the like to be laminated harder or the same strength as the resin foams 15a and 15b having a wavy uneven structure. In addition, excessive sinking can be suppressed while maintaining cushioning properties.
That is, taking a mat material as an example, it is possible to obtain a mat material that is lightweight, has excellent design, and has excellent moisture resistance and heat insulation, so that it can be exposed and used on the floor of a gymnasium such as a disaster area. .. As described above, the laminated bodies 1a and 1b can be used as a bed because they have excellent moisture resistance and can suppress excessive sinking while maintaining the cushioning property, and also serve as a bed for an evacuation center. It can be suitably used as a mat material. Further, if the laminated bodies 1a and 1b are laminated bodies having a predetermined size and shape, they can be used as a partition for a partition having excellent assembly independence as described later.

(Third Embodiment)
Next, a third embodiment will be described. FIG. 8A is a diagram showing a state in which the cushion members 1 are arranged so as to face each other. The surfaces of the wave-shaped uneven structure of the pair of cushioning materials 1 are arranged so as to face each other. The present embodiment relates to a method of using a cushion material in which two cushion materials 1 are stacked and used as a laminated structure of the cushion material 1. Here, the laminated structure means a structure in which cushion materials are used by overlapping them, and the laminated portions do not necessarily have to be bonded or bonded to each other, and the flat surfaces of the cushion materials are fixed to each other by a hook-and-loop fastener. Alternatively, the structure may be such that the corrugated uneven structure surfaces of the cushion material are arranged so as to face each other.

FIG. 8B is a diagram showing a laminated structure 40 in which the peaks and valleys of the pair of cushioning materials 1 are combined and laminated with each other. That is, FIG. 8B is a diagram showing a method of using a cushion material in which two cushion materials 1 are stacked and the cushion material 1 is laminated and used. The mountain portion 5a formed on one cushion material 1 (lower part in the figure) and the valley portion 7b formed on the other cushion material 1 (upper part in the figure) are arranged so as to face each other. Similarly, the valley portion 7a formed on one cushion material 1 (lower part in the figure) and the mountain portion 5b formed on the other cushion material 1 (upper part in the figure) are arranged to face each other. In this way, by overlapping the forming surfaces of the corrugated uneven structure of the cushion material 1 with each other, the corrugated concave and convex structures mesh with each other, and the linear patterns 11 are formed side by side on substantially the same plane. The sheet-like laminated structure 40 is formed.

FIG. 9A is a diagram showing a state in which the peaks 5 and valleys 7 of the pair of cushioning materials 1 face each other with the flat portions facing each other, and FIG. 9B shows the pair of cushioning materials 1 It is a figure which shows the laminated structure 40a which was laminated. That is, FIG. 9B is a diagram showing a method of using the cushion material 1 in which the flat surfaces of the cushion material 1 are used so as to face each other. The surfaces of the wave-shaped uneven structure of the pair of cushioning materials 1 are directed outward in opposite directions, and the flat surfaces that are the back surfaces of the wave-shaped uneven structure are brought into contact with each other, and the contact surfaces are hook-and-loop fasteners as necessary. They may be fixed to each other by fixing means such as. At this time, the mountain portion 5a formed on one cushion material 1 (lower part in the figure) and the valley portion 7b formed on the other cushion material 1 (upper part in the figure) are separated from each other by a predetermined distance toward the outside. Is placed. Similarly, the valley portion 7a formed on one cushion material 1 (lower part in the figure) and the mountain portion 5b formed on the other cushion material 1 (upper part in the figure) are separated from each other by a predetermined distance toward the outside. Is placed.

That is, the valley portion 7b of the other cushion material 1 is located on the back surface of the mountain portion 5a of one cushion material 1, and the mountain portion 7a of the other cushion material 1 is located on the back surface of the valley portion 7a of the other cushion material 1. The portion 5b is located. By stacking the flat surfaces so as to face each other in this way, as shown in FIG. 9B, in the laminated structure 40a, the forming surface of the corrugated uneven structure of 1 of the cushion material is formed on the outer surfaces on both sides of the laminated structure 40a. Since the structure is oriented toward the surface, a wavy uneven structure is formed substantially parallel to both sides, and a large number of linear patterns 11 are formed side by side on the outer surface, so that a panel-like laminated structure having excellent design can be realized. ..

FIG. 10 is a sectional view taken along line FF of FIG. 8B. As shown, the adhesive layer 17a and the adhesive layer 17b of each cushion material 1 are arranged so as to be adjacent to each other. That is, the linear patterns 11 (adhesive surfaces or fusion surfaces) arranged between the peaks and valleys of the cushion material 1 constituting the laminated structure 40 are arranged adjacent to each other on substantially the same plane. Will be done. In this way, by overlapping the forming surfaces of the corrugated uneven structure of the cushion material 1 with each other, the linear patterns 11 can be formed so as to be lined up on substantially the same plane.

Here, in the plan view of the laminated structure 40, the appearance of the adhesive layers 17a and 17b (adhesive surface or fused surface) arranged adjacent to each other on substantially the same plane with respect to the apparent total area of the plane including the adhesive surface. The total occupancy rate of is preferably 80% or more, and more preferably 90% or more. In this way, in the laminated structure 40 formed by facing the pair of cushion materials 1, the adhesive layers 17a and 17b can be arranged on the same plane over substantially the entire surface. Therefore, when the adhesive layers 17a and 17b are provided with functionality such as vibration damping property and flame retardancy, the function can be exhibited on substantially the entire surface of the laminated structure 40. In this way, a functional plane can be formed by the adhesive surface or the fusion surface arranged adjacent to each other on substantially the same plane.

It should be noted that such a laminated structure in which cushioning materials are laminated is suitable as, for example, a partition material for an evacuation center or a shock absorbing wall panel material. When emphasizing design, a laminated structure of corrugated concavo-convex structure is arranged on the outer surface, and when functionality is used, the corrugated concavo-convex structure is arranged so as to face each other to impart functionality. Arrange the surface in a substantially straight line. When a laminated structure having a wavy uneven structure is arranged on the outer surface, it can be used as it is, but a dedicated stand may be provided. In this case, it is desirable that the two cushioning materials are fixed by using a hook-and-loop fastener or the like on the side surface of the end portion of the cushioning material.

According to the third embodiment, the same effect as that of the first embodiment can be obtained. Further, by combining cushioning materials to form a laminated structure, such a laminated structure can be used as a counter or wall panel material at a disaster prevention site. With such a laminated structure, the conventional corrugated cardboard mats and partitioning materials are provided with functionality such as heat insulation, cushioning, and moisture resistance, which has forced evacuation life at the evacuation site. It is possible to provide the victims with a clean and comfortable living environment as much as possible.

Further, by superimposing the corrugated uneven structures of the resin foams 15a and 15b so as to face each other, the positions where the periodic linear pattern 11 appearing on the corrugated surface is formed are substantially matched. Can be made to. That is, the linear pattern 11 (adhesive surface or fusion surface) is formed so as to penetrate the inside of the combined resin foams 15a and 15b and be arranged in a substantially planar shape. For example, by imparting sound insulation and vibration damping properties to the adhesive layer (or fusion layer) constituting the linear pattern 11, in addition to design and cushioning properties, quietness and vibration damping properties are imparted. It becomes possible to do.

In this way, a large number of adhesive surfaces and fused surfaces are arranged in a rectangular shape, a circular shape, or an elliptical shape on the profiled surface. Therefore, when the profiled surfaces face each other, there are some gaps, The bonding surface and the fusion surface can be arranged on substantially the same plane. Therefore, it is possible to add additional functions such as vibration damping and quietness to the portion. Further, the resin foams 15a and 15b sandwiching the resin foams 15a and 15b can also be provided with deodorant property, antibacterial property, antiviral property and the like.

In addition, by assembling a wavy uneven structure, the thickness of the laminated structure is about twice the thickness of the cushion material, so when used as a partition material for partitions, etc., the assembly independence should be improved. Can be done. Further, it goes without saying that there is no problem in assembly independence even when the wavy uneven structure is arranged on the outer surface.

(Fourth Embodiment)
Next, a fourth embodiment will be described. FIG. 11 is a plan view of the cushion material 1c. The cushion material 1c has substantially the same configuration as the cushion material 1, but differs in that the cushion material 1c is composed of a plurality of colors.

As described above, the surface 3 of the cushion material 1c has a mountain portion 5 formed by the resin foam 15b above the linear pattern 11, a linear pattern forming portion 13 on which the linear pattern 11 is formed, and a line. It is divided into three portions with a valley portion 7 formed by the resin foam 15a below the pattern 11. In the present embodiment, at least one or two portions of the peak portion 5, the linear pattern forming portion 13 and the valley portion 7 are formed in a color different from that of the other portions.

For example, the linear pattern forming portion 13 is colored differently from the peaks 5 and the valleys 7, or only the linear pattern forming portion 13 is colored, so that the linear pattern forming portion 13 is colored differently from other portions. It is also possible to form the linear pattern 11. Further, by coloring either the mountain portion 5 or the valley portion 7 of the wavy uneven structure in a different color, a three-dimensional three-dimensional pattern in which either the mountain portion 5 or the valley portion 7 is colored is formed. can do.

For example, when the linear pattern 11 is formed by the fusion layer, when the surface of the resin foam forming the fusion layer crystallizes in the process of solidification after melting, the degree of crystallinity and the change in molecular orientation, In addition to this, different colors may be formed by superimposing the residual effect of ADCA on the foam surface. Alternatively, one of the fused surfaces of the resin foam to be fused may be fused using a resin foam coated with a different color. Even in this way, the linear pattern forming portion 13 can be colored in a color different from that of the peak portion 5 and the valley portion 7.

Further, when the linear pattern 11 is formed by the adhesive layer, the adhesive layer formed by using the colored adhesive may be obtained by adding a pigment to the adhesive forming the adhesive layer. Even in this way, the linear pattern forming portion 13 can be colored in a color different from that of the peak portion 5 and the valley portion 7.

Further, in order to manufacture such a cushion material 1c, for example, resin foams 15a and resin foams 15b of different colors may be used. As shown in FIG. 6A, the resin foams 15a and the resin foams 15b of different colors are bonded to each other to form a laminated resin foam 39, and profile processing is performed to change the color of the peak 5 or the valley 7 to another. It can be different from the color of the part. That is, in addition to the two-dimensional pattern of the linear pattern forming portion 13, both the peak portion 5 and the valley portion 7 of the wavy uneven structure are colored in different colors, so that the linear pattern forming portion 13 , Each of the mountain portion 5 and the valley portion 7 can form a three-dimensional three-dimensional pattern colored in different colors.

Further, FIG. 12A is a plan view of the cushion material 1d, and FIG. 12B is a side view of the cushion material 1d. The cushion material 1d has substantially the same structure as the cushion material 1c, but differs from the cushion material 1c in that the area of the mountain portion surrounded by the linear pattern 11 is formed to be small.

Similar to the cushion material 1c, the surface 3 of the cushion material 1d includes a mountain portion 5 formed by the resin foam 15b above the linear pattern 11 and a linear pattern forming portion 13 on which the linear pattern 11 is formed. , It is divided into three portions with a valley portion 7 formed by the resin foam 15a below the linear pattern 11. The cushion material 1d is similar to the cushion material 1c in that at least one or two portions of the peak portion 5, the linear pattern forming portion 13 and the valley portion 7 are formed in a color different from that of the other portions.

On the other hand, in the cushion material 1d, when the slice position at the time of profile processing shown in FIG. 6B is offset upward, or when the resin foam 15a and the resin foam 15b form the laminated resin foam 39, the upper side is formed. By making the thickness of the resin foam 15b thicker than that of the lower resin foam 15a, the area of the mountain portion surrounded by the linear pattern 11 can be made smaller. As a result, a cushion material as shown in FIG. 12B can be obtained.

According to the fourth embodiment, the same effect as that of the first embodiment can be obtained. Further, by making at least a part of the mountain portion 5, the valley portion 7, and the linear pattern 11 a color different from other portions, higher designability can be obtained. In particular, higher design can be obtained by changing the colors of the mountain portion 5 and the valley portion 7 and the mutual area ratio.

At this time, with the position of the linear pattern 11 as the boundary line, a three-dimensional design in which the peak portion 5 and the valley portion 7 (including the bottom portion) are colored in different colors from the linear pattern 11 when not colored is created. Obtainable.

Further, by offsetting the slicing position within the wavy shape formed by the adhesive surface or the fused surface, the formation height of the linear pattern 11 is an arbitrary height within the wavy uneven structure. It is possible to form in. For example, by forming the linear pattern 11 on the mountain portion 5 side from the center of the height of the wavy uneven structure, it is possible to form the linear pattern 11 or the colored mountain portion 5 in a smaller pattern. is there. Further, by forming the linear pattern 11 on the valley portion 7 side from the center of the height of the wavy uneven structure, it is possible to form a large pattern of the linear pattern 11 or the colored mountain portion 5. .. In this way, the design can be changed by changing the colored areas of the mountain portion 5 and the valley portion 7.

(Fifth Embodiment)
(Connection structure of partition for shelter compartment using laminated body)
FIG. 13 is a diagram showing a shelter section 50. This will explain the structure of the partition for the shelter. The laminated body 1a is substantially rectangular in which the length of the long side is twice the length of the short side. The shelter compartment 50 is composed of a plurality of laminated bodies 1a, and has a floor portion 52 (disaster mat material) and a wall portion 54 (partition side wall for division). Two laminated bodies 1a are arranged on the floor 52 with a disaster mat that can also be used as a bed on the floor so that the long sides of the substantially rectangular shapes are brought into contact with each other to form a substantially square section. Further, with the laminated body 1a erected in the short side direction, the long side of the laminated body 1a is placed on the floor surface so as to surround the outer circumference of the floor portion 52 formed of the disaster mat as the substantially square floor material. As a contact surface with, the laminate 1a is connected and fixed by connecting the vicinity of the end of the short side of the flat surface on the back surface of the laminate 1a and the side end surfaces on the short side at substantially right angles to each other by repeating the process a plurality of times. It is a connection structure in which a wall portion 54 is formed, and is a connection structure including at least a section in which a U-shaped side wall having a substantially square opening is formed.

A hook-and-loop fastener is used as the fixing means used to form the connection structure of the partition for the shelter, but a button-shaped fastener or a magnet fixed to a tape-shaped member can be used instead of the hook-and-loop fastener. The fixing means is attached to the vicinity of the end portion of the short side of the laminated body 1a and at predetermined positions on the side surface of the end portion. In the connection structure of the partition for the shelter of the present invention, since the fixing means is attached to the laminate, the laminates face each other and come into contact with each other without requiring a separate fixing component. The biggest feature is that a partition for partitioning can be formed by fitting. In the surface fastener, the back surface of the surface fastener is fixed to the laminate with an adhesive or an adhesive, and in the tape-like member to which the button-shaped fastener or the magnet is attached, the tape-like member is fixed to the laminate with an adhesive or an adhesive. be able to.

At this time, the side surface of the end on the short side of the disaster mat is oriented in either a direction substantially parallel to the plan view or a direction substantially perpendicular to the adjacent mountain portion of the profile processing surface and the curve passing through the mountain portion. , Cut in a substantially straight line at a position (1/4) pitch-shifted from the top of the mountain or the top of the valley. As a result, a substantially rectangular cut surface can be obtained as the cut surface on the side surface of the end on the short side. By fixing the fixing means to the side surface of the end having such a flat substantially long cross section, the fixing means can be fixed efficiently, and there is no need to process a tape-shaped fixing means such as a hook-and-loop fastener. become. Further, in the connection structure of the evacuation center section, the connection structure of the evacuation center section may use a cushion material instead of the laminated body.

In the connection structure of the shelter section 50 of the fifth embodiment, the cushion material 1 to which the sheet-like foam is attached to the back surface may be used instead of the laminate 1a as the partition material for the section. The cushion material 1 has a height (Hv) from the flat surface of the cushion material 1 to the valley portion and a height (Hc) from the flat surface of the cushion material 1 to the center line height (Hc) of the valley portion 7a and the mountain portion 5a. It is desirable to secure a ratio R of 50% or more.

Here, in the fifth to eighth embodiments, if the design is sacrificed, the profile is replaced with the laminate 1a having a large number of annular linear patterns between the peaks and valleys. Even if a laminated body without a linear pattern is used on the processed surface, the connection structure of the evacuation center section using the laminated body that can be easily assembled and disassembled without using tools or special parts, and the evacuation center using the laminated body. A method of forming a section, a method of disassembling and storing the evacuation center section, and a method of forming a shock absorbing wall panel of the evacuation center section can be obtained.

(Sixth Embodiment)
(Method of forming a partition for a shelter using a laminated body)
Next, the sixth embodiment will be described. This will be described with reference to FIG. 13 used in the connection structure of the partition for the shelter using the laminated body. FIG. 13 is a diagram showing a shelter section 50.
The shelter compartment 50 is composed of a plurality of laminated bodies 1a, and has a floor portion 52 (disaster mat material) and a wall portion 54 (partition side wall for division). The laminated body 1a can be obtained by laminating another sheet-shaped resin foam on a surface opposite to the surface of the cushion material 1 having a corrugated uneven structure and adhering or fusing it. Alternatively, as described above, it can also be obtained by slicing the second and third layers with a slicing machine using a four-layer laminated resin foam. As described above, a plurality of layers of cushioning material in which another sheet-like resin foam is laminated and adhered or fused to the surface of the cushioning material 1 opposite to the surface on which the corrugated uneven structure is formed. Is referred to as a laminated body.

Next, a method of forming the evacuation shelter section 50 shown in FIG. 13 will be described. The laminate 1a used in the structure of the evacuation center section 50 is, for example, a substantially rectangular resin foam sheet having a long side length of 1800 mm × a short side length of 880 mm × a thickness of 30 mm (average thickness is 25 mm). That is, the laminated body 1a is substantially rectangular in which the length of the long side is twice the length of the short side. A wavy uneven structure having a linear pattern is formed on one surface of the laminated body 1a, and a flat surface is formed on the other surface. For the laminate 1a, a resin foam having a foaming ratio of 20 to 40 times is used. For example, when the foaming ratio is 30 times, the weight of the laminate is about 1.25 kg. Even if the foaming ratio is 20 times, it is about 1.9 kg, which is 2 kg or less. Further, although the average thickness is allowed up to 50 mm, it is preferable that the thickness of the laminated body is thin, and 40 mm or less is sufficient, considering the storability in normal times other than in the event of a disaster. Therefore, the weight of the laminated body is 5 kg or less at the maximum and does not exceed 4 kg.

First, the floor 52 of the evacuation center section 50 is formed. By arranging either the flat surface or the uneven surface of the plurality of laminated bodies 1a toward the floor surface, the floor portion 52 can be formed on the floor surface. By arranging the two laminated bodies 1a with their long sides aligned with each other, a substantially square floor portion 52 is formed, and a floor portion 52 having an area of about 2 tatami mats is formed. That is, the laminated body 1a is arranged on the floor surface as a disaster mat that can also be used for a bed so that the long sides of the substantially rectangular shapes are brought into contact with each other to form a substantially square section. Here, the laminated body 1a forms a floor portion 52 having cushioning properties and excellent moisture-proof and heat-insulating properties.

Next, a wall portion 54 for dividing the division is formed with respect to the floor portion 52 of the evacuation center division 50. The wall portion 54 is arranged so as to surround three sides of a substantially square-shaped region having an area of about 2 tatami mats formed by the two laminated bodies 1a. That is, in a state where the laminated body 1a is erected in the short side direction, the long side of the laminated body 1a is covered with the disaster so as to surround the outer periphery of the disaster mat that can be used as a bed as a substantially square floor material. As a contact surface with the mat, the ends of the short sides are connected to each other at a substantially right angle.

More specifically, first, the laminated body 1a is erected on the floor portion 52 so that the long side of the laminated body 1a is in contact with the floor portion 52 having a substantially square shape. By sequentially connecting the short sides of the three laminated bodies 1a standing on the floor portion 52 at substantially right angles to each other, it is possible to form a substantially U-shaped wall portion 54 in which one of the substantially square sections is open. it can. In this way, by using the laminated body 1a as a partition for partitioning, a U-shaped side wall in which one of the substantially square sections is open is formed and partitioned, which is an evacuation center section, which is one section of the evacuation center. 50 can be formed. At this time, the side surface of the end on the short side of the disaster mat is oriented in either a direction substantially parallel to the plan view or a direction substantially perpendicular to the adjacent mountain portion of the profile processing surface and the curve passing through the mountain portion. , Cut in a substantially straight line at a position shifted by (1/4) pitch from the top of the mountain or the top of the valley. As a result, a substantially rectangular cut surface can be obtained as the cut surface on the side surface of the end on the short side. By obtaining the end side surface of the laminated body having such a shape, it becomes possible to efficiently bond the tape-shaped member to which the surface fastener or the fixing means is attached to the end side surface of the laminated body, and the tape. Processing to match the side surface of the end of the shaped member becomes unnecessary.

The notated square-shaped section obtained in this way, which is surrounded by the laminated body 1a on three sides, is used as the basic section, and the first section is formed. Next, a substantially square second section is formed adjacent to the first section. More specifically, the floor portion 52 of the second compartment is formed consecutively from the floor portion 52 of the first compartment in the same manner as the first compartment. That is, adjacent to the disaster mat that can also be used as the floor material of the first compartment, the bed as the floor material of the second compartment having a substantially square shape and the same size using the laminated body 1a. Form a disaster mat that can also be used. Next, a U-shaped wall portion 54 that opens in the direction opposite to the first section is arranged to form a second section. In this way, using the laminated body 1a, the laminated body 1a is continuously opened in the direction opposite to the first section in succession with the first section formed in a U shape, and shares a U-shaped end piece. By forming the U-shaped side wall as the second compartment, at least two U-shaped compartments can be formed.

Then, like the first and second compartments, a U-shaped wall that opens in the opposite direction to the second compartment after forming the floor 52 of the third compartment adjacent to the second compartment. The portion 54 can be arranged to form a third compartment. That is, the openings of the substantially square compartments are sequentially formed in a U shape so as to open in the opposite directions, and the side wall portions of the compartments are sequentially and repeatedly formed, and corresponding to the side wall portions, substantially A large number of compartments can be formed by repeatedly forming a disaster mat that can also be used as a bed as a square floor material.

In this way, a substantially square floor portion 52 is formed, and the long sides of the laminated body 1a are brought into contact with each other on the floor portion 52 to form the wall portion 54, thereby forming a substantially U-shaped section. be able to. At this time, at least two or three substantially square-shaped sections are formed by forming a continuous U-shaped wall portion 54 between adjacent sections so as to open in opposite directions to form a partition for the section. The including shelter compartment 50 can be formed.

Further, a plurality of substantially square floor portions 52 are formed so as to be adjacent to each other, and a U-shaped wall portion 54 is formed so that the opening directions of the adjacent floor portions 52 are opposite to each other. This may be repeated sequentially. By doing so, it is possible to form a shelter compartment 50 in which a large number of compartments are continuously arranged.

In this forming method, the flat surface of the laminated body 1a may be arranged toward the floor surface. That is, as the floor material, either the flat surface of the laminated body 1a or the corrugated uneven structure surface may be arranged toward the floor surface. Further, the U-shaped wall portion 54 formed by the laminated body 1a may be arranged so that the flat surface on the opposite side to the wave-shaped uneven structure surface which is the pattern forming surface of the laminated body 1a is alternately arranged. .. For example, with respect to the side wall portion arranged in a U shape formed by the laminated body 1a, a wavy uneven structure surface which is a pattern forming surface of the laminated body 1a of the laminated body 1a is formed along each side of the partition. The shelter compartment 50 may be formed by alternately arranging them in the order of outer, inner, and outer, or by arranging them alternately in the order of inner, outer, and inner. With such an arrangement, the design of the criticized place can be enhanced. At the same time, it can be excellent in soundproofing, moistureproofing and heat insulating properties. Therefore, the evacuation center user can spend comfortably in the predetermined section. As described above, when forming the section, the direction of the corrugated uneven structure surface may be appropriately selected in consideration of the design, which direction should be directed along each side of the section.

Further, when assembling the laminated body 1a as a partition for partitioning, the laminated bodies 1a may be connected to each other by a hook-and-loop fastener on which a large number of microprojections attached to the surface of the laminated body 1a are formed. In this way, the evacuation shelter section 50 can be easily assembled by simply connecting the laminated bodies 1a to each other with a hook-and-loop fastener. Further, since the laminated body 1a is as light as about 1.5 kg per sheet, it is also excellent in transportability during assembly. Further, the laminated body 1a for the evacuation center section 50 is formed by laminating another sheet-shaped resin foam on the surface opposite to the wavy uneven structure of one cushion material 1 having a pattern on the surface. Therefore, it is also excellent in assembly independence when used as a wall portion 54.

Here, "excellent assembly independence" means that the laminated bodies 1a are connected to each other when the laminated bodies 1a are fixed to each other by, for example, a hook-and-loop fastener, in order to form a shelter section 50 by the laminated body 1a. Since the center of gravity of the laminated body 1a is stable even on the opposite end surface other than the portion fixed by the hook-and-loop fastener, the upper part of the short side of the erected laminated body 1a is assembled in a self-supporting manner without tilting or bending. Is possible.

When connecting the laminated body 1a, it is desirable that the end portion of the flat surface of one laminated body 1a in the width direction and the end surface of the other laminated body 1a are brought into contact with each other and connected by a hook-and-loop fastener. For example, the hook-and-loop fastener is attached to a predetermined position from the upper end to the lower end in the long side direction of the flat surface of the laminated body 1a, or from the upper side to the lower predetermined position of the portion corresponding to the flat portion of the end surface of the laminated body. Will be done. More specifically, it is desirable that the hook-and-loop fasteners be attached to at least three places in the height direction: upper part, middle part, and lower part.

For example, a hook-and-loop fastener is attached to one of the laminated bodies 1a at predetermined positions of the upper end portion, the middle portion and the lower end portion in the width direction of the flat surface of the laminated body 1a, and above the end surface of the other laminated body 1a. , Attach the hook-and-loop fastener to the middle part and the lower part at the predetermined position. Here, the fixing positions of the fixing means such as the hook-and-loop fastener may be arranged as described above, but may be evenly arranged from the upper end portion to the lower end portion, as long as the laminated bodies can be stably connected and supported. There is no particular problem.

If the attachment positions of the surface fasteners of one laminate 1a and the other laminate 1a correspond to each other, the surface fasteners attached to the flat surface of one laminate 1a and the other laminate 1a The laminated bodies 1a can be connected to each other by facing each other with the hook-and-loop fasteners attached to the end faces. In this way, the surface fasteners attached to the predetermined positions on the flat surface and the surface fasteners attached to the end surfaces are opposed to each other to connect the two. At this time, if the laminated body 1a having excellent assembly independence is used, unnecessary gaps are not generated in the assembled partition for partitioning, and the assembling property is also excellent.

Here, as the fixing means used for forming the partition for the shelter, a hook-and-loop fastener has been described, but a button-shaped fastener or a magnet fixed to the tape-shaped member can be used instead of the hook-and-loop fastener. .. In addition, the effect is the same as in the case of the connection structure of the partition for the shelter. In the surface fastener, the back surface of the surface fastener is fixed to the laminate with an adhesive or an adhesive, and in the tape-like member to which the button-shaped fastener or the magnet is attached, the tape-like member is fixed to the laminate with an adhesive or an adhesive. be able to.

Although the details will be described later, the laminated body 1a having excellent assembly independence includes the height (Hv) from the flat surface of the laminated body 1a to the valley portion 7a and the valley portion 7a and the mountain portion from the flat surface of the laminated body 1a. It is desirable that the ratio of the height to the center line height (Hc) of 5a is 50% or more. More preferably, it is 60% or more.

In the method of forming the evacuation center section 50, instead of the laminated body 1a, the cushion material 1 having a wavy uneven structure having a linear pattern formed on the surface may be used as the partition material for the section. In order to make the cushion material 1 excellent in assembly independence, the height (Hv) from the flat surface to the valley portion of the cushion material 1 and the valley portion 7a and the mountain portion 5a from the flat surface of the cushion material 1 Similarly, it is desirable that the ratio of the height to the center line height (Hc) is 50% or more.

(Relationship between the cutting position of the laminated body and the shape of the cross section of the cut end side surface)
Here, in the fifth to seventh embodiments, looking at the cut surface to which the fixing means of the laminated body 1a is bonded, FIGS. 14A to 14C show the cutting position of the laminated body and the cut surface. The relationship between the shapes of the cross sections of the side surfaces of the ends is shown. FIG. 14A shows the cutting position as seen from the profiled surface of the laminate. FIG. 14B shows a cut surface (cut surface 71 connecting the tops of the peaks) when cut on a curve that alternately passes through the tops of the peaks and the bottoms of the valleys. FIG. 14C shows a cut surface (cut surface 70 connecting the inflection points) when the inflection point positions separated by (1/4) pitch from the top of the mountain portion and the bottom of the valley portion are cut so as to linearly connect them. ..

When the laminate 1a is cut substantially linearly on a curve that alternately passes through the top of the mountain and the bottom of the valley along the XX line of FIG. 14A, the unevenness of the cut surface becomes the largest as shown in FIG. 14B. The cross-sectional area of the parallel portion of the end face of the laminated body is the smallest. On the other hand, the inflection point position where the laminated body 1a is (1/4) pitch-shifted in either a direction substantially parallel to a plan view or a direction substantially perpendicular to the curve that alternately passes through the top of the mountain and the bottom of the valley. By cutting in a substantially straight line so as to connect the two, a cut surface having a substantially long shape with the least unevenness of the cut surface can be obtained, and the cross-sectional area of the parallel portion of the end surface of the laminated body becomes the largest. For example, when cutting along the YY line of FIG. 14A, as shown in FIG. 14C, the unevenness of the cut surface is the smallest, a substantially long cut surface is obtained, and the cross-sectional area of the parallel portion of the end surface of the laminated body is the largest. growing. At this time, the inflection point of the curve from the apex of the mountain portion to the bottom of the valley portion of the adhesive layer or the fusion layer and the profile processed surface, which is the boundary between the resin foam 15a and the resin foam 15b forming the peak and the valley. When they match, a linear pattern of a predetermined length is formed periodically at the upper end of the cut substantially parallel cross section. When the linear pattern is formed at a position shifted above or below the inflection point, the linear pattern does not appear on the cut surface. Here, when the line connecting the top of the mountain and the bottom of the valley is not curved but straight, connect the intermediate position between the top of the mountain and the bottom of the valley or the intermediate position between the bottom of the valley and the top of the valley. By cutting in a substantially straight line, a substantially rectangular cut surface similar to that in the case of having an inflection point was obtained, and the same behavior was confirmed.

Further, since the mountainous valleys of this profiled surface have the same periodic structure in the directions orthogonal to each other, from the tops of the mountainous portions in either of the two orthogonal directions, which are substantially parallel to the plan view or substantially perpendicular to each other. It is possible to cut in a substantially straight line so as to connect the positions of the turning points in the middle to the bottom of the valley or in the middle from the bottom of the valley to the top of the mountain. Here, more strictly speaking, considering the periodic structure of the mountain part valley, such an inflection point position is located from the adjacent mountain top to the mountain top on the profile machined surface, or from the valley bottom to the valley. Assuming that the distance to the bottom is 1 pitch, it is understood from the drawing showing the cutting position in FIG. 4A that applications are periodically filed at positions of (1/4), (3/4), and (5/4) pitches. it can. More strictly, it is possible to cut at every (2N + 1) / 4 (N: natural number) pitch. It is also possible to cut in the same direction between the XX line of FIG. 14A and the YY line of FIG. 14B. In that case, a cut surface having smaller irregularities on the cut surface but having irregularities on the cut surface can be obtained as compared with the case of cutting with the XX line of FIG. 14A. In this case, when the cutting position is close to the XX line, the size of the unevenness is close to the case of cutting with the XX line, and when the cutting position is close to the YY line, the size of the unevenness is the YY line. By approaching the case of cutting, the surface becomes flat, but if necessary, such a cutting method is also possible.

The area of the flat portion to which the fixing means is attached differs depending on the cutting position of the laminated body. Therefore, if the cross section having the largest parallel portion area on the side end surface is selected and that portion is used as the cutting portion, the area to which the fixing means such as the surface fastener is attached can be maximized. Cut so as to connect the position shifted by (1/4) pitch from the line connecting the top of the mountain and the bottom of the valley, and the bottom of the valley and the top of the mountain, that is, the inflection point position of the curve connecting the mountain and the valley. Therefore, the side end face can be formed in a substantially rectangular shape having the largest parallel portion area on the side end face by reducing the narrow portion of the width of the side end face, which is a periodic uneven structure of the cut side end face. As a result, the width of the tape-shaped member of the fixing means to be bonded to the side end surface can be maximized, and therefore a strong connection structure can be obtained.

(How to disassemble and store the evacuation center)
Next, a method of disassembling and storing the evacuation center section will be described. 15A and 15B are views showing a storage state of the shelter section 50 formed by the method described above, FIG. 15A is a front view, and FIG. 15B is a plan view. When the evacuation center section 50 is stored, the end face of the laminated body 1a is fixed and stored on the wall surface 51.

In order to disassemble and store the evacuation center section 50, first, the laminated body 1a forming the evacuation center section 50 is disassembled. After disassembling the laminated body 1a, one laminated body 1a is fixed to the wall surface 51 by arranging the flat surface toward the wall surface 51. At this time, as the fixing means used for fixing, there are other fixing means, but here, the case of the hook-and-loop fastener 53 will be described. The hook-and-loop fasteners 53d are arranged at predetermined positions on both sides of the flat surface of the laminated body 1a, and the hook-and-loop fasteners 53c are arranged at positions on the wall surface 51 corresponding to the arrangement positions of the hook-and-loop fasteners 53d. Therefore, the laminated body 1a can be fixed to the wall surface 51 by the surface fasteners 53c and 53d. That is, by bringing the surface fastener 53d of the first laminated body 1a into contact with the surface fastener 53d of the wall surface 51, the laminated body 1a is erected and fixed to the wall surface 51.

Further, the corrugated concave-convex structure surface of the back surface of the flat surface of the laminate 1a erected and fixed to the wall surface 51 is superposed on the corrugated concave-convex structure surface of the second laminate 1a, and the first laminate is formed. The end faces of 1a are aligned to form a stack of two sheets. After that, the third and fourth laminated bodies 1a, which are new laminated bodies 1a, are subjected to the flat surface, which is the respective laminated surface, and the wavy uneven structure surface, which is the first and second laminated body 1a. Each laminated surface and end surface are aligned and erected in the same order as in the case of. That is, the flat surfaces and the wavy concave-convex structure surfaces are sequentially opposed to each other, and the end surfaces of the respective end surfaces are aligned and erected repeatedly.

After that, the laminated body 1a is stacked in the same procedure. When the number of stacked sheets is an odd number according to the number of stacked layers 1a, the final stacking surface is a flat surface, the outermost surface is a wavy uneven structure surface, and the number of stacked sheets is an even number. The final stacking surface is a wavy uneven structure surface, and the outermost surface is a flat surface. In this way, the laminated bodies are sequentially repeated and stacked to stand upright.

Here, the surface fastener 53c is attached to a predetermined position on the end surface of the laminated body 1a. Therefore, by arranging another surface fastener 53b having a length corresponding to the total thickness of the laminated layers 1a so as to straddle the surface fastener 53a on the end surface of each of the erected laminated bodies 1a, all the layers are laminated. The end faces of the body 1a can be fixed together.

Here, as the fixing means used for the method of disassembling and storing the shelter compartment of the partition for the shelter, the surface fastener has been described, but the button-shaped fastener or the magnet fixed to the tape-shaped member is used as the surface fastener. It can be used instead. Also in the method of disassembling and storing the partition for the shelter, the partition for the shelter can be easily disassembled and stored by using a button-shaped fastener or a magnet fixed to the tape-shaped member as the fixing means. In the surface fastener, the back surface of the surface fastener is fixed to the laminate with an adhesive or an adhesive, and in the tape-like member to which the button-shaped fastener or the magnet is attached, the tape-like member is fixed to the laminate with an adhesive or an adhesive. be able to. At this time, it goes without saying that the fixing means used for the method of disassembling and storing the shelter section of the partition for the shelter section is the same as the fixing means used for assembling the laminate used for assembling the shelter section.

As described above, the laminated body 1a used in the evacuation center section 50 can be disassembled and stored. At this time, the surface of the wavy uneven structure in which the linear pattern is formed on the surface of the laminated body 1a is arranged so as to be the outermost surface, and can be stored compactly. At this time, since the end face shape of the laminated body 1a is used by assembling the evacuation center section 50, the end face of the laminated body 1a to be attached and fixed at the time of assembly has a mountain portion and a mountain portion adjacent to the profile processed surface as described above. It is cut in a substantially straight line at a position (1/4) pitch deviated from the top of the mountain or the top of the valley in either the direction substantially parallel to the plane view or the direction substantially perpendicular to the passing curve. As a result, a substantially rectangular cut surface can be obtained as the cut surface on the side surface of the end on the short side. By obtaining the end side surface of the laminated body having such a shape, it becomes possible to efficiently bond the tape-shaped member to which the surface fastener or the fixing means is attached to the end side surface of the laminated body, and the tape. Processing to match the side surface of the end of the shaped member becomes unnecessary.

In the above-mentioned disassembly and storage method of the evacuation shelter section, the cushion material 1 having a wavy uneven structure having a linear pattern formed on the surface may be used instead of the laminated body 1a.

(How to form a shock absorbing wall panel in an evacuation center)
16A and 16B are views showing the impact absorbing wall panel 60 of the evacuation center section, FIG. 16A is a front view, FIG. 16B is a plan view, and FIG. 16C is an enlarged view of the vicinity of the hook-and-loop fasteners 53c and 53d of FIG. 16B. Is. The method of forming the shock absorbing wall panel 60 is as follows. First, as described above, the shelter compartment 50 formed in the method of forming the shelter compartment using the laminated body 1a is disassembled. Here, as in the case described above, the surface fastener will be used as the fixing means.

Next, the flat surface of the disassembled laminated body 1a is arranged toward the wall surface 51. At this time, the surface fasteners 53d are arranged at predetermined positions on both sides of the flat surface of the laminated body 1a, and the surface fasteners 53c are arranged at predetermined positions on the wall surface 51 corresponding to the arrangement positions of the surface fasteners 53d. That is, when the short side of the laminated body 1a is continuously arranged as an upright surface parallel to the wall surface 51, the surface fastener is placed at a predetermined position on the wall surface 51 in accordance with the arrangement position of the surface fastener 53d on the flat surface of the laminated body 1a. 53c is arranged. Therefore, the laminated body 1a can be fixed to the wall surface 51 with the uneven surface facing the indoor side by the surface fasteners 53c and 53d.

The flat surface of the other laminated body 1a is directed toward the wall surface 51, and the corrugated uneven structure surface is arranged toward the indoor side so as to be continuous with the initially fixed laminated body 1a, and the predetermined position of the wall surface 51 is arranged. It is fixed to the wall surface 51 by the surface fastener 53c arranged in. Further, by fixing the laminated body 1a to the wall surface 51 one after another so as to be continuous with the laminated body 1a fixed to the wall surface 51 immediately before, the shock absorbing wall panel 60 of the evacuation shelter section can be formed. As described above, in the present embodiment, the uneven surface of the laminated body 1a is fixed to the wall surface 51 toward the indoor side when it is not used as the floor portion 52 or the wall portion 54 of the evacuation center section 50 or as a tsuitate. A shock absorbing wall panel 60 having a predetermined size and excellent design can be formed on the wall surface 51.

In addition, instead of the laminated body 1a, a cushion material 1 having a wavy uneven structure in which a linear pattern is formed on the surface may be used. Even in this case, the cushioning material 1 constituting the evacuation center section 50 can be disassembled to form the shock absorbing wall panel 60. As described above, the laminated body 1a can be used as a disaster mat material that can be used as a partition side wall for a shelter or a bed in the event of a disaster, and is usually used as a wall panel material for shock absorption. It is possible to do.

Here, as the fixing means used for the method of forming the shock absorbing wall panel of the evacuation shelter section, the surface fastener has been described, but a button-shaped fastener or a magnet fixed to the tape-shaped member is used instead of the surface fastener. Can be done. In addition, in the method of forming the shock absorbing wall panel of the evacuation center section, the same fixing means can be used as the fixing means. In the surface fastener, the back surface of the surface fastener is fixed to the laminate with an adhesive or an adhesive, and in the tape-like member to which the button-shaped fastener or the magnet is attached, the tape-like member is fixed to the laminate with an adhesive or an adhesive. be able to. At this time, it goes without saying that the fixing means used for the method of forming the shock absorbing wall panel of the evacuation center section is the same as the fixing means used for assembling the laminate used for assembling the evacuation center section.

(Evaluation by evaluation test of assembly independence of laminated body)
Since the partition for the side wall section (wall portion 54) in which a plurality of laminated bodies 1a are joined by a hook-and-loop fastener needs to have cushioning properties, the laminated body 1a used for this is not necessarily highly rigid. For this reason, a test was conducted to confirm the independence of the partition for the side wall section during the assembly work. FIG. 17 is a diagram showing an explanatory view of an assembly independence test of a partition partition, and FIG. 18A is a diagram showing the dimensions of each part of the laminate 1a used for evaluating the assembly independence of the partition.

The evaluation of the independence during the assembly work is performed by imitating the partition for the side wall section, that is, the long side length direction (I in the figure) 1800 mm × height direction (J: short side direction) 880 mm of the laminated body 1a. A laminated body 1a', 1a'' was prepared. The two laminated bodies 1a ′ and 1a'' that were cut were arranged so as to be orthogonal to each other so that the lengthwise portions of the two laminated bodies 1a ′ and 1a ″ were laid horizontally and in contact with the floor surface, respectively. ..

As shown in FIG. 17, the end portion of the flat surface of one laminate 1a ″ in the length direction and the side end surface of the other laminate 1a ″ in the length direction were connected to each other by a hook-and-loop fastener. The laminated bodies 1a'and 1a' are connected at three positions in the height direction, with the upper surface fastener attaching portion 61a, the intermediate surface fastener attaching portion 61b, and the lower surface fastener attaching portion 61c. , Both were connected. That is, on one of the laminated bodies 1a', surface fasteners are attached to the upper, middle and lower portions of the flat surface of the laminated body 1a'in the length direction, respectively. Further, a hook-and-loop fastener is attached to the other laminated body 1a ″ at predetermined positions above, in the middle, and below in the height direction, which is the side end surface of the laminated body 1a ″ in the length direction.

By connecting the surface fasteners attached to the flat surface of one laminate 1a'and the surface fasteners attached to the side end surfaces of the other laminate 1a'' so as to face each other, the laminate can be formed. It is possible to create a connection structure that is connected orthogonally to each other. The assembly independence was evaluated using the connection structure of this laminated body. The laminated body is cut in a straight line at a position that is (1/4) pitch-shifted substantially parallel to the plan view from the position where the surface unevenness is the largest, which is a curve connecting the peaks of the profiled surface of the laminated body. Since it was used, it is possible to obtain a substantially parallel cut surface corresponding to the sheet thickness before profile processing on the side end surface of the laminated body. Here, the average thickness of the laminate used in the examples is 20 mm to 30 mm. Since the laminate used in the examples was cut so as to obtain a substantially parallel cut surface having a thickness corresponding to the average thickness of the laminate, a hook-and-loop fastener having a size of 150 mm × 20 mm could be used on the end surface of the laminate without any problem. It can be pasted, and the bearing capacity of the hook-and-loop fastener can be effectively used.

The laminate 1a used in the test was formed by slicing with a profile processing machine using a polyethylene foam sheet having a foaming ratio of 40 times. At this time, in order to evaluate the influence of the dimensional shape of the wavy uneven structure on the surface of the laminated body on the assembly independence, the wavy uneven structure portion such as the flat portion in the thickness direction and the mountain part valley portion of the laminated body is evaluated. Laminates of various dimensions and shapes were prepared in which the ratio of the thickness to the total thickness was different. It has a wavy uneven structure obtained in this way, a periodic linear pattern is formed on the front surface, and a laminated body in which a sheet-like resin foam is laminated on the back surface is used as a test material for assembly independence. Evaluation was performed. The results of the evaluation of assembly independence are shown in Tables 1 and 2.

In Tables 1 and 2, the height (Hm) from the flat surface to the mountain portion corresponds to the sheet thickness (maximum thickness) of the laminated body as shown in FIG. 18A. The height from the flat surface to the ridge (Hm) corresponds to the sum of the thickness of the sheet-like foam and the height of the cushioning material to the ridge. Further, the height (Hv) from the flat surface to the valley portion corresponds to the thickness (minimum thickness) of the laminated body at the bottom of the valley portion 7a as shown in FIG. 18A. The height from the flat surface to the valley (Hv) corresponds to the sum of the thickness of the sheet-like foam and the height of the cushion material to the valley. Further, as shown in FIG. 18A, the height (Hc) from the flat surface of the laminated body to the center line of the wavy uneven structure is laminated with the center line K of the top of the mountain portion 5a and the bottom of the valley portion 7a. It is the distance from the flat surface on the back of the body. That is, it is calculated as Hc = Hv + (Hm-Hv) / 2 = (Hm + Hv) / 2. The wave-shaped processing height (half-value width of the uneven structure) in Tables 1 and 2 corresponds to (Hm-Hv) / 2.

Further, in Tables 1 and 2, in the assembly independence evaluation, in the laminated body connection structure shown in FIG. 17, bending or bending occurs at the upper tip of the widthwise end portion on the side opposite to the connection portion by the hook-and-loop fastener. Those that did not exist were designated as "good", and those that had slight bending or bending even if the upper tip was about 2-3 mm were designated as "not enough". That is, it was determined that the laminated body in which the end face on the side opposite to the connecting portion of the hook-and-loop fastener does not bend or bend is excellent in assembly independence. As described above, if the laminated body having excellent assembly independence is used, unnecessary gaps are not generated in the assembled partition for partitioning, and the assembling property is also excellent.

As can be seen from Tables 1 and 2, the height (Hc) of the center line height (Hc) from the flat surface to the wavy uneven structure surface, which is the back surface, with respect to the height (Hv) from the flat surface to the valley portion, which is the back surface of the laminate. The relationship between assembly independence and R was evaluated for the following test materials, where R was used as a percentage of the ratio of heights up to. In Tables 1 and 2, the test materials 1 to 4 have a case where the R value is changed from 44% to 62% by changing the wave shape processing height while keeping the mountain portion height of the laminated body constant at 40 mm. Shown. For the test materials 5 to 8, test materials 9 to 11, and test materials 12 to 15, the average thickness of the laminated body is kept constant at 30 mm, 25 mm, and 20 mm, respectively, and the corrugated processing height (half width of the uneven structure). This is an example of a test material when is appropriately changed. Here, as described above, "not enough" is the one that is slightly deformed, "good" is the one that has no problem in assembly independence, and the decrease in assembly independence is prevented even after long-term storage. Those that could be evaluated were evaluated as "excellent".

The R of the test material 1, the test material 5, and the test material 12 in the test material 1 to the test material 15 in which the wave shape processing height is variously changed in the range of the average height of the above laminated body of 20 mm to 30 mm is 50% or less. Although there was a slight amount of bending and bending, when R was 50% or more, a laminated body having excellent assembly independence could be obtained without such slight bending or bending. I was able to confirm that. Further, when the foam is used in an evacuation center, it is stored for a long period of time. Therefore, considering the decrease in assembly independence due to a slight decrease in strength over time during storage, it is desirable that R is 60% or more. It is desirable to have. As a fixing means used for confirming the independence of assembly, a button-shaped fastener or a magnet fixed to a tape-shaped member may be attached to the laminate instead of the hook-and-loop fastener. Similar confirmations were made using button fasteners and magnets as fixing means, but similar results were obtained in this case as well.

The reason for this is thought to be as follows. The cross-sectional area of the mountain region above the center line K and the cross-sectional area of the valley region below the center line K are equivalent. Here, the mountain portion 5a is shifted to the valley portion 7a side and inverted, and a fictitious sheet-like foam having a thickness of the center line height (Hc) of the wavy uneven structure surface from the flat surface which is the back surface of the laminated body. Consider the body (see FIGS. 18B and 18C). In this case, since the volume of the peak portion 5a and the volume of the valley portion 7a are the same, the position of the center of gravity of the laminated body (L in FIG. 18C) is considered to be substantially the same as the center line of the fictitious sheet-shaped foam. This can be easily understood from the fact that the two foams obtained by slicing at the center of the sheet thickness of the sheet-shaped foam by profile processing have substantially the same weight. In this case, if the condition that R is 50% or more can be satisfied, the position of the center of gravity is arranged on the flat surface side of the valley portion 7a of the end surface of the laminated body, and the laminated body becomes stable. Become. Here, more preferably, if the condition of 60% or more is satisfied, the foam becomes more stable.

As can be seen from the results of the above-mentioned confirmation test of polyethylene foam sheet assembly independence with a foaming ratio of 40 times, if a harder material or a material having a foaming ratio of 40 times or less is used, the assembly independence is more advantageous than this material. become. Therefore, using a resin foam having a foaming ratio of 40 times or less, the sheet-like foam on the back surface of the laminate with respect to the height (Hv) from the flat surface of the sheet-like foam on the back surface of the laminate to the valley portion of the laminate. If a laminate is used in which the ratio of both the heights from the flat surface to the center line height (Hc) of the wavy uneven structure surface is expressed as a percentage of 50% or more, there is a problem in assembly independence. There is no. In addition, this laminate is lightweight, and a partition partition having excellent design can be easily assembled.

Here, in the laminated body 1a in which another sheet-like foam is attached to the back surface side of the cushion material 1 having a wavy uneven structure on the front surface, the sheet-like foam provided on the back surface is more than the cushion material 1. A hard resin foam may be used. Even in this case, the position of the center of gravity of the laminated body is slightly moved toward the hard sheet-like foam side, so that the assembly independence is further improved. Therefore, a more stable state can be obtained if at least the same relationship as when the laminate is made of the same material is satisfied.

The cushion material 1 may be used instead of the laminated body 1a. Also in this case, as the cushion material 1, the percentage display R of the ratio of both the height Hv from the flat surface to the valley and the center line height Hc of the wavy uneven structure surface from the flat surface on the back surface of the cushion material 1. However, if the cushion material 1 satisfying the relationship of 50% or more is used, the same assembly independence as the laminated body 1a can be obtained even if the cushion material is not provided with the sheet-like foam on the back surface.
