TECHNICAL FIELD OF THE INVENTION
The present invention relates to an ecological-type architectural heat insulating panel and a method of manufacturing the same, which enable effective use of wood by thinning and waste materials.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, heat insulating materials have been used for walls, floors, and the like of buildings. As a typical example, fiber-based heat insulating materials such as glass wool are generally known.
The fibrous heat insulating material is used to fill the space between the outer wall plate and the inner wall plate, thereby subdividing the space to confine the air and prevent heat conduction by convection.
However, there is a problem that air convection is generated although it is substantially fine, and the heat insulation effect is reduced. In addition, problems such as corrosion due to dew condensation and the like are likely to occur.
Further, other petroleum-based heat insulating materials and the like generate harmful chemical substances at the time of waste incineration, and are difficult to dispose or regenerate. Therefore, resources cannot be reused.
[0003]
On the other hand, the present applicant has proposed using a natural material as the heat insulating material. In this method, a plurality of corrugated paperboards each having a corrugated core as a heat insulating material are laminated and bonded so that the corrugated cores are orthogonal to each other (see Patent Document 1). It is a heat-insulating material that is suitable, inexpensive, and suitable for recycling resources.
In addition, not only corrugated cardboard but also carbonized cork is a heat insulating material having an air layer formed therein, and can be used as a natural material that is similarly inexpensive and rich in heat insulation.

[Problems to be solved by the invention]
In order to use the above-mentioned heat insulating material as a heat insulating material for a building along a wall surface of a building, conventionally, at a construction site, the heat insulating material is fixed along the inner surface of an outer wall plate, and the surface of the heat insulating material is fixed. The inner wall plate was fixed to the wall.
[0006]
However, in such a conventional method of constructing a heat insulating material, the plate material and the heat insulating material are separately transported to a construction site for installation and installation, which is troublesome. There was a problem that the handling of the material was troublesome, and the heat insulating material was damaged during transportation and construction.
[0007]
In addition to the above, the present inventor (the inventor) paid attention to thinned wood as a wooden panel material used as an outer wall plate or an inner wall plate of a building.
[0008]
Thinned lumber is wood that has been cut down for so-called thinning in the process of planting and growing artificial forests such as cedar and cypress, and is constantly generated. However, when these thinned lumbers are lumbered, only long and narrow boards can be obtained, but they cannot be used as structural material panels.
For this reason, it can be used only for limited applications such as fuel such as firewood, charcoal, and other handicrafts as so-called eco-products, and at present it is difficult to treat a large amount of thinned wood.
In order to use these thinned materials as plate materials for buildings, the present applicant arranges the thinned materials side by side in the width direction, and in this juxtaposed state, a linear or rod-shaped connecting member made of a natural material orthogonal to the width direction. It was connected to obtain a wooden board connection panel.
[0009]
However, when the above-mentioned wooden board connection panel is used as a panel material for a building, the use thereof is limited because the wooden board connection panel is easily bent in the width direction and lacks rigidity.
[0010]
The present invention has been made based on the above idea, and an object of the present invention is to provide an ecological-type architectural heat insulating panel which is easy to handle and operate, is inexpensive and robust, and a method of manufacturing the same.
[0011]
[Means for Solving the Problems]
Hereinafter, means for solving the above problem will be described with reference to the drawings corresponding to the embodiments.
In other words, the architectural heat insulating panel 40 according to the present invention has the front and back panel materials 20, 20 mainly composed of natural wood laminated and bonded to the front and back surfaces of the plate-like heat insulating material 30 or 50 formed into a thick plate shape. It is a three-layer structure heat insulating panel for buildings, wherein the panel member 20 is formed by connecting a plurality of wooden board pieces 10 having a predetermined width in a state of being juxtaposed in the width direction. Each of the wooden board pieces 10 connected in a state of being arranged in the width direction is connected by a long connecting member 12 orthogonal to the width direction. The connecting member 12 is desirably in the shape of a line or a rod made of a natural material such as bamboo string or cotton string.
[0012]
The above-mentioned structure is characterized in that the wood panel pieces 10 of the front panel material 20 and the back panel material 20 are arranged in parallel with the plate-shaped heat insulating material 30 or 50 interposed therebetween.
With such a structure, the wood board piece 10 has rigidity in the longitudinal direction and can be bent in the width direction, and can be mounted in a curved manner.
[0013]
Alternatively, in the above-described structure, the direction in which the front panel material 20 and the rear panel material 20 are arranged side by side is orthogonal to the plate-shaped heat insulating material 30 or 50.
With such a structure, the heat insulating panel 40 has rigidity in the vertical and horizontal directions.
[0014]
Further, as shown in FIGS. 6 and 7, the architectural heat insulating panel 42 according to the present invention has a structure in which a plurality of intermediate plate-like heat insulating materials 30 or 50 are juxtaposed via a wooden spacer 60. It is characterized by the following.
The spacer 60 improves the strength of the heat insulating panel 40 in the thickness direction and also improves the strength when driving a metal fitting such as a nail or a screw.
[0015]
Further, the plate-like heat insulating material 30 or 50 is characterized in that it is a structure in which a natural material such as corrugated paper or carbonized cork is formed into a plate shape with a predetermined thickness.
[0016]
According to the heat insulating panel 40 for a building according to the present invention, the front and back panel materials 20, 20 mainly composed of natural wood are laminated on the front and back surfaces of the plate heat insulating material 30 or 50 formed into a thick plate shape. Because of the integrated structure of the three bonded layers, handling is easy, and the plate-like heat insulating material made of a natural material is not damaged during transportation or construction work.
In addition, it has a rigidity as a whole with a three-layer structure, and can be used as a heat insulating structural wall material inside and outside a building.
Furthermore, the entire structure has an ecological structure made of natural materials, and there is almost no pollution at the time of waste incineration. Further, in the panel material 20 forming the outer surface of the heat insulating panel 40, there is a gap between the wooden board pieces 10, and the wooden board piece 10 itself expands and contracts according to the outside air humidity and the like. Also, since it expands and contracts in the direction of opening when drying and closing in the case of high humidity, the disadvantage that the internal plate-like heat insulating material 30 or 50 becomes moist and molds is prevented.
[0017]
Furthermore, as shown in FIGS. 8 to 10, the architectural heat insulating panel 43 according to the present invention has the same panel material 20 as described above laminated and adhered to one surface of the same plate-like heat insulating material 30 or 50 as described above. An integrated structure with two layers can be provided.
As shown in FIG. 10, such a two-layer heat insulating panel 41 can be used, for example, as a cast-out formwork for pouring concrete when building a concrete structure. In this case, the heat insulating panel 43 is formed integrally with the outer surface (or inner surface) of the concrete wall surface by fixing the plate heat insulating material 30 (50) side of the heat insulating panel 43 to the concrete side and integrally fixing the heat insulating panel 43 to the concrete wall surface. .
[0018]
Further, in the method for manufacturing a heat insulating panel for a building as described above according to the present invention, the sheet heat insulating material 30 or 40 having a structure in which corrugated paper or carbonized cork is formed into a plate with a predetermined thickness, and a predetermined width. The front and back panel members 20, 20 having a structure in which a plurality of wooden board pieces 10 are arranged side by side in the width direction and connected by a linear or rod-shaped long connecting member 12 orthogonal to the width direction, are prepared. In a state where an adhesive is applied between the material and the front and back panel materials, press bonding is performed.
[0019]
According to such a manufacturing method, it becomes possible to efficiently manufacture the heat insulating panel for building according to the present invention. In addition, by using a non-polluting adhesive such as a vinyl acetate adhesive as an adhesive, there is no inconvenience such as generation of harmful gas at the time of incineration disposal. Further, the adhesion between the intermediate plate-like heat insulating material 30 or 40 and the front and back panel materials 20 is strong and structurally stable.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 to 4 show a first embodiment of the present invention.
1 and 2 show a panel member 20 applied to the present invention. In the figure, each of the wooden board pieces 10 constituting the panel material 20 is obtained by sawing a thinned wood material such as cedar, cypress, hiba, and red pine, and the size of each of the wooden board pieces 10 is the size of the finally obtained panel material 20. Although it is appropriately selected depending on the size, it is preferable to be sawn into a rectangular plate having a width of about 600 to 900 mm, a thickness of about 10 to 30 mm, and a length of about 1000 to 2400 mm.
[0021]
In the embodiment shown in the drawings, in the sawing process, convex portions 10a and concave portions 10b that fit each other are formed on both sides in the width direction of each wooden board piece 10, and each wooden board 10 is aligned in a horizontal line in the width direction. As a result, the adjacent wooden boards 10 are fitted to each other.
In addition to this, grooves 10c penetrating in the width direction are formed on the surface of each assembled wooden board piece 10 at appropriate intervals in the length direction.
Then, as shown in the figure, the wooden board pieces 10 are gathered in a horizontal row, and are fixed and joined in a vertical direction by applying lateral pressure from both sides in the width direction.
[0022]
In the drawings, the projections 10a and the depressions 10b are formed in a wedge shape, but a joint shape used in other general wood and wood groups can be adopted. Further, although the shape of the groove 10c is substantially semicircular in cross section and the connecting member 12 is formed as a round bar, the cross section of the groove 10c is dovetail, and the connecting member 12 having a cross section suitable for this is press-fitted. By the fitting, complete removal is prevented after molding, and the tensile strength in the width direction of each wooden board 10 is reinforced by the connecting member 12.
[0023]
As the wood board pieces 10, other lumber and waste materials can be used in addition to the thinned wood. In addition, as the wooden board pieces 10, ordinary long boards without the above-mentioned uneven portions can be juxtaposed and used.
[0024]
The connecting member 12 may be a rope-shaped member having a high flexibility in addition to a bamboo string which is a material having a high rigidity in a pulling direction. Specific examples of the rope-like member include natural materials such as cotton strings, hemp ropes, and palm ropes.
[0025]
Next, the production of the heat insulating panel 40 using the panel material 20 will be described with reference to FIGS.
First, a laminated corrugated paper is used as the plate-shaped heat insulating material 30. As shown in an enlarged view of a part of FIG. 3, this laminated corrugated paper is a general corrugated cardboard 32 having a corrugated core 32a made of hard paper as a center and an outer skin 32b made of hard paper stuck on the upper and lower sides. The cores 32a are vertically stacked and bonded in multiple layers so that they are perpendicular to each other. After applying an adhesive to the laminated surfaces and superimposing them, applying heat and pressure with a press molding machine to press-mold integrally to the required thickness It was done.
As the adhesive used for this bonding, it is desirable to use a vinyl acetate-based adhesive for the same reason as described above, and at the same time, to contain insect repellents, preservatives, etc. harmless to the human body.
[0026]
An adhesive is applied to the front and back of the plate-shaped heat insulating material 30 made of the laminated corrugated cardboard, and then the panel material 20 is arranged on the front and back, and heat pressure is applied by a press machine to complete the integral architectural heat insulating panel 40. I do.
As the adhesive used for this bonding, it is preferable to select a vinyl acetate-based adhesive for the same reason as described above.
[0027]
Further, as shown in the drawing, the bonding surface (back surface) of the connecting member 12 is used as the bonding surface, and the front and back panel materials are sandwiched by the plate heat insulating material 30. It is preferable to make the joining directions of 20 orthogonal. The reason for this is that in the former case, the grain is arranged neatly on the surface side in the finished state of the heat insulating panel 40, and the latter reason is to make the joining direction of the front and back different from each other as in the case of general laminated plywood. This is to bring about isotropic strength.
[0028]
Further, the joining direction of the front and back panel materials 20 can be made parallel with the plate-shaped heat insulating material 30 interposed therebetween. With such a structure, the heat insulation panel 40 can be used in a curved state.
[0029]
Further, although only a part of the heat insulating panel 40 is shown in the drawing, in actual production, in addition to being formed into a vertical and horizontal thickness dimension suitable for building materials, it is cut according to the use after forming, and is cut to a fixed size. Molded into panels. The plate-shaped heat insulating material 30 may be formed to have a predetermined size in advance and appropriately joined or juxtaposed.
[0030]
The above-mentioned heat insulation panel 40 can be used for the inner wall and the heat insulation floor of a building as an interior panel that also serves as heat insulation by utilizing the texture of the grain such as the straight grain or the grain of the panel material 20 on the front and back surfaces. In addition, since it has sufficient strength, it can be used for a sufficient purpose as a structural material such as a wall material or a floor material of a panel-installed wooden house such as a 2 × 4 type.
[0031]
FIG. 5 shows a second embodiment of the present invention. This heat insulating panel 41 is the same as the above-described embodiment except that a plate material of carbonized cork is used as the plate-shaped heat insulating material 50.
Carbonized cork is obtained by carbonizing cork bark in the ground. The heat insulation panel 41 using carbonized cork is rich in heat insulation as in the above-described embodiment, and can be used as a structural material such as an inner wall or a heat-insulated floor of a building or a wall or a floor as in the above-described embodiment. .
[0032]
6 and 7 show a third embodiment of the present invention. The heat insulating panel 42 has a structure in which a plurality of plate heat insulating materials 30 (50) are arranged side by side with a wooden spacer 60 interposed therebetween. The spacer 60 is made of a square material having substantially the same thickness as the plate-like heat insulating material 30 (50). The installation position of the spacer 60 and the installation position of the connecting member 12 on the heat insulating panel 42 are the same in the thickness direction. The connecting member 12 is provided on the surface side of the plate-shaped heat insulating material 30 (50).
[0033]
With such a structure, the strength in the thickness direction of the heat insulating panel 42 is improved, and there is no possibility that the plate-shaped heat insulating material 30 (50) is crushed. In addition, when the heat insulating panel 42 is fixed by nailing or the like, or when a metal fitting or the like is driven into the plate-like heat insulating material 30 (50), the metal fitting is driven into the spacer 60 portion, whereby the fixing is strengthened. Furthermore, the metal fitting is driven into the spacer 60 portion on the back portion by driving the metal fitting with the connecting member 12 provided on the front surface as a guide.
[0034]
8 to 10 show a fourth embodiment of the present invention. The heat insulating panel 43 has a two-layer structure, and the panel material 20 is bonded and fixed to one surface of the plate-shaped heat insulating material 30 (50) by pressing.
[0035]
For example, as shown in FIG. 10, such a two-layer heat insulating panel 43 is used as a form of a dumping die for pouring concrete 70 when a concrete structure is built. In this case, the heat insulating panel 43 is formed integrally with the outer surface (or inner surface) of the concrete wall surface by fixing the plate-like heat insulating material 30 (50) side of the heat insulating panel 43 to the concrete side and integrally fixing the heat insulating panel 43 to the concrete wall surface. Will be. In the figure, reference numeral 71 denotes a facing frame, and 72 denotes a holding rod for holding between the inner and outer frames.
[0036]
In the third or fourth embodiment, portions corresponding to the second or third embodiment are denoted by common reference numerals, and detailed description thereof is omitted.
[0037]
【The invention's effect】
As is apparent from the above description, according to the architectural heat insulating panel of the present invention, a panel material mainly composed of natural wood is provided on the front and back surfaces or one surface of the plate-like heat insulating material formed into a thick plate. Because it is an integrated structure with three or two layers laminated and bonded, it is easy to transport and handle at a construction site, and during transportation or construction work, a fragile plate-like insulation made of natural material may be damaged. I can't.
[0038]
In addition, it has rigidity due to a three-layer or two-layer structure as a whole, and can be used as a heat insulating structural wall material inside and outside a building.
[0039]
Furthermore, the entire structure has an ecological structure made of natural materials, and there is almost no pollution at the time of waste incineration.
[0040]
In addition, the panel material forming the outer surface of the heat insulating panel has a gap between the wood board pieces, and the wood board pieces themselves expand and contract according to the outside air humidity, etc., and the gaps between the juxtaposed wood board pieces also open during drying. In addition, at the time of high humidity, since it expands and contracts in the closing direction, the inconvenience of the inside plate-like heat insulating material becoming moist and moldy is prevented, which is healthy.
[0041]
Furthermore, by providing the plate-shaped heat insulating material via the wooden spacer, the strength of the heat insulating panel in the thickness direction is improved, and fixing by nailing or the like and driving of metal fittings are easily and reliably performed.
[0042]
Further, the architectural heat insulating panel according to the present invention has a two-layer structure in which a panel material is adhered and fixed to one surface of a plate-like heat insulating material, and is used as a form for throwing away concrete for pouring concrete when building a concrete structure. As a result, the plate-like heat insulating material is integrally fixed to the concrete wall surface, and the concrete wall having the heat insulating structure can be easily obtained.
[0043]
Further, in the method for manufacturing a building insulating panel according to the present invention as described above, a plate-shaped heat insulating material having a structure in which corrugated paper or carbonized cork is formed into a plate with a predetermined thickness, and a plurality of wooden boards having a predetermined width. Adhesion is made between the plate-like heat insulating material and the front and back panel materials using a front and back panel material having a structure in which pieces are arranged side by side in the width direction and connected by a linear or rod-like long connecting member orthogonal to the width direction. Since the press-press bonding is performed in a state where the agent is applied, it becomes possible to efficiently manufacture the above-described heat insulating panel for building according to the present invention.
[0044]
In addition, when press bonding is performed, for example, when a plywood is used as the front and back panel materials, there is a possibility that an adhesion failure portion may occur in an intermediate portion or the like, or swelling may occur during use due to a temperature difference or the like. However, in the present invention, as described above, the front and back panel members having a structure in which a plurality of pieces of wood board having a predetermined width are arranged in the width direction and connected by a linear or rod-shaped long connecting member orthogonal to the width direction. Because even if there is a defective bonding part in a part of the wood board piece, since the other wood board piece is bonded to the plate-shaped heat insulating material, the middle board-shaped heat insulating material and the front and back panels There is no inconvenience such as exfoliation of the material, and there is no danger that the middle portion of the panel material will expand during use.
