Description

  The present invention relates to a floor structure using a panel for floor assembly that is mainly installed as a floor of a balcony or the like.

  The floor of a balcony such as a house is often formed by manufacturing a floor panel at a factory and fixing the floor panel to the housing while assembling the floor panel at the site.

  For example, in Patent Document 1, a floor panel for connecting with a waterproof sheet that is thinner than the panel body is sandwiched between floor panels in which a waterproof sheet is previously attached to the panel body. A waterproof floor structure is disclosed in which the attached waterproof sheet is extended from the end of the panel body to the connecting floor panel side.

  The structure of such a waterproof floor is excellent in design because the surface of the waterproof floor can be substantially smooth without a step by overlapping two extended waterproof sheets on the upper surface of the connecting floor panel. Met.

  However, in the case of the floor structure as in Patent Document 1, when the panel body expands and contracts due to a difference in temperature, the waterproof sheet is positioned directly above the floor panel (between the floor panel and the connecting floor panel). Excessive stretching stress was concentrated only on the part, and there was a risk that the waterproof sheet in this part would swell, whitening or cracking would occur. Thus, when damage, such as a crack, occurs in the waterproof sheet, water enters between the panel body and the waterproof sheet, and there is a risk that water leaks downward from between the panel body and the panel body. In addition, a separate factory line is required to produce a thin connecting floor panel, which increases costs and makes it difficult to adjust the dimensions of the floor panel and connecting floor panel when installing the floor on a balcony. There was also a problem.

  The present invention has been made in view of the above problems, and the problem to be solved is that the expansion and contraction of the covering material can be prevented by not concentrating the stretching stress only on the covering material positioned directly above the floor assembly panel. An object of the present invention is to provide a floor structure using a floor assembly panel that prevents breakage, has high designability and waterproofness, and is easy to assemble.

  In order to achieve the above object, a floor structure using a floor assembly panel according to the present invention comprises a floor assembly panel in which a soft or semi-hard coating material is adhered to the surface of a panel body with a first adhesive. And a floor structure in which a gap is provided between the panel bodies, the first panel covering material extending to the second panel side, and the second panel covering material first panel With the side edge deducted, the covering edge of the first panel and the covering edge of the second panel are abutted, and at least on the second panel body of the extending covering material of the first panel While sticking the area | region located to a 2nd panel main body with the 2nd adhesive agent more flexible than said 1st adhesive agent, the coating | covering material edge of a 1st panel, and a 2nd panel The seam portion that is abutted with the coating material edge is sealed or welded.

  The floor structure using another floor assembly panel according to the present invention comprises a panel assembly body comprising a floor assembly panel in which a soft or semi-hard coating material is adhered to the surface of the panel body with a first adhesive. The first panel covering material is extended to the second panel side and the end of the second panel covering material on the first panel side. And a predetermined gap is formed between the covering edge of the first panel and the covering edge of the second panel, and at least a second of the extended covering material of the first panel is formed. The area located on the panel body is adhered to the second panel body with a second adhesive that is more flexible than the first adhesive, and the edge of the first panel covering material The second adhesive is filled in the gap between the second panel and the edge of the covering material of the second panel.

  In the floor structure using the floor assembly panel described above, it is preferable that the second adhesive is filled in the gap between the first panel and the second panel. In addition, the second panel side end portion of the first panel body and the first panel covering material located above the end portion are or / and the first panel covering material of the second panel. It is preferable that the second panel body located on the side and the second panel body located below the second panel body is attached with a second adhesive, and the upper edge on the second panel side of the surface of the first panel body. It is more preferable that a cut surface is provided on the upper end side on the first panel side of the second panel body surface.

  Next, in the floor assembly panel set of the present invention, the covering material of the first panel is extended to the second panel side, and the end on the first panel side of the covering material of the second panel is deducted. When the first panel and the second panel are arranged in a dimension for the floor assembly panel set, in which the dimension of the covering material of the first panel is the dimension excluding the covering material of the second panel. It is characterized in that it is longer than the dimension obtained by adding the width dimension of the gap between the panel bodies provided in the panel.

  In the floor structure forming method using the floor assembly panel set according to the present invention, the first panel and the second panel of the floor assembly panel set are arranged with a gap between the panel bodies. The first panel covering material is overlaid on the second panel covering material, and the first panel covering material and the second panel covering material in the overlapped portion are desired. Cut at the seam forming location, but match both edges of the covering material, apply a flexible second adhesive to the surface of the panel body, and / or the second adhesive to the surface of the panel body Is applied, the gap between the first panel and the second panel is filled with the second adhesive, and the covering material is adhered, and a new seam portion where both the covering material edges are abutted is sealed. Or it is characterized by welding.

  According to another method of forming a floor structure using a floor assembly panel of the present invention, the first panel and the second panel of the floor assembly panel set described above are provided with a gap between the panel bodies. The first panel covering material and the second panel covering material in the overlapping portion are overlapped with each other and fixed to the casing, and the first panel covering material is overlapped on the second panel covering material. To form a predetermined gap between both edges of the covering material, and apply a flexible second adhesive to the surface of the panel body, and / or to the second surface of the panel body. In addition, the second adhesive is filled in the gap between the first panel and the second panel, and the coating material is adhered, and the second adhesive is applied to the gap between the two coating material edges. It is characterized by filling the adhesive agent.

  In the floor structure using the floor assembly panel of the present invention, at least a portion where the covering material of the first panel is extended is stuck to the surface of the second panel body with a flexible sticking agent. Even if the gap between the panel bodies expands and contracts due to the difference in temperature, and the gap distance fluctuates, the elastic stress generated at that time causes the flexible second adhesive and the second adhesive Since it is dispersed over the entire area of the covering material pasted by the agent and does not concentrate only on the covering material located directly above the gap between the panel bodies, the covering material on the gap between the panel bodies It is possible to prevent swelling, whitening and cracking. As described above, by preventing the covering material from being swollen or damaged, it is possible to improve designability and waterproofness, and it is not necessary to separately manufacture panels having different thicknesses, which is preferable in terms of economy and workability.

  Further, in the floor structure using another floor assembly panel of the present invention, at least a portion where the covering material of the first panel is extended is pasted on the surface of the second panel body with a flexible adhesive. Therefore, even if the gap between the panel bodies expands and contracts due to the difference in temperature, and the gap distance fluctuates, the expansion and contraction stress generated at that time causes the flexible second adhesive and its The gap between the panel bodies is distributed over the entire area of the coating material adhered by the second adhesive and does not concentrate only on the coating material located immediately above the gap between the panel bodies. It is possible to prevent the upper covering material from being swollen or from being whitened or cracked. In addition, a predetermined gap is formed between the coating material edge of the first panel and the coating material edge of the second panel, and this gap portion is filled with the second adhesive in the gap. Since the stretching stress is also dispersed by the second adhesive filled in the film, there is no concern that the edges of both coating materials will swell, and the waterproofness is further improved.

  In addition, the floor structure using the floor assembly panel in which the second adhesive is filled in the gap between the first panel and the second panel has a flexible second adhesive. By filling the gap provided between the panel main bodies, even if water enters between the panel main body and the covering material, the water is stopped by the flexible adhesive, Waterproofing between the first panel and the second panel is ensured.

  In particular, the second panel side end portion of the first panel body and the first panel covering material positioned above the first panel body and / or the first panel covering material of the second panel The area where the second adhesive is applied, like the floor structure where the second panel main body located on the lower end and the second panel body is attached with the second adhesive, By increasing to the second panel side of the panel body and / or the coating material end of the second panel, the effect of preventing the swelling and damage of the coating material due to the dispersion of the stretching stress described above is more remarkable. Become. Also, since the second adhesive is applied at the time of construction, when applying the second adhesive to the first panel body, the panel body is made by rolling up the covering material of the first panel. When it becomes possible to easily fill the flexible second adhesive in the gap between them, and when applying the second adhesive to the edge of the covering material of the second panel, By raising the covering material of the second panel, the second adhesive does not adhere to the surface of the covering material without performing masking or the like, so that the workability is high.

  Further, a floor structure in which a cut surface is provided on the upper end side of the first panel body surface on the second panel side or / and on the upper end side of the second panel body surface on the first panel side. When the second adhesive is applied on the panel body, the second adhesive is naturally filled in the gaps between the panel bodies, so that waterproofing can be easily performed. In addition, the concave portion formed by the cut surface and the end face of the panel body adjacent to the cut surface is filled with the second adhesive, thereby increasing the thickness of the layer to which the second adhesive is applied. Since the layer of the adhesive becomes difficult to break, the waterproof property is further improved.

  Next, in the floor assembly panel set of the present invention, the covering material of the first panel is extended more than the dimension obtained by adding the gap dimension between the panel bodies to the dimension obtained by subtracting the covering material of the second panel. When the floor assembly panel set is fixed to the housing with a certain gap, the extended end portion of the first panel overlaps the end portion of the deducted covering material of the second panel. become. By cutting and cutting off the overlapping parts of the covering materials with a cutting tool such as a cutter, the edges of the covering materials can be perfectly matched, and the seam treatment can be performed neatly. Can be secured. In addition, by using such a floor assembly panel set, even if there is an error in the assembly of the panel or an error in adhering the covering material to the panel body, the error can be adjusted when cutting the covering materials. It becomes possible and workability is good.

  And the formation method of the floor structure using the panel set for floor assembly of the present invention makes it possible to clean the seam by using the panel set for floor assembly, and can prevent the covering material from being swollen or damaged. Needless to say, a floor structure using a floor assembly panel having excellent waterproofness and design can be easily formed.

  In addition, the floor structure forming method using another floor assembly panel set of the present invention also uses a floor assembly panel that prevents the covering material from swelling and breakage in the same manner as the above floor structure forming method. A floor structure can be easily formed. Furthermore, if a predetermined gap is formed between the coating material edge of the first panel and the coating material edge of the second panel, and the gap is filled with the second adhesive, the gap is filled. Further, since the stretching stress is dispersed by the second sticking agent and there is no concern that the edges of both covering materials are swollen, a floor structure having a very good waterproof property can be formed.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

The floor structure using the floor assembly panel of the present invention shown in FIG. 1 and FIG. 2 is a structure using the floor assembly panels 1 and 2 installed mainly as a floor of a balcony or the like. The panel main body 1a of the panel 1 and the panel main body 2a of the second panel 2 are arranged with a gap 5 between them, and are fixed to the arm 8 of the frame. The width dimension W of the gap 5 between the first panel body 1a and the second panel body 2a is preferably about 0.5 to 3 mm, and thus, between the panel bodies 1a and 2a. By providing the gap 5 and fixing it to the arm 8, it is possible to prevent the panel bodies 1a, 2a from being pushed up or damaged even if the panel bodies 1a, 2a and the arm 8 are thermally expanded or contracted due to a temperature difference. be able to.
The first panel 1 and the second panel 2 are fixed to the arm 8 by known fixing means such as bolts / nuts and screws.

  As shown in FIGS. 1 and 2, soft covering materials 1 b and 2 b are respectively attached to the surfaces of the first panel main body 1 a and the second panel main body 2 a by the first adhesive 3. The covering material 1b of the first panel 1 is extended to the second panel 2 side. The end of the covering material 2b of the second panel 2 on the first panel 1 side is a gap provided between the panel bodies 1a and 2a from the extending dimension E of the covering material 1b of the first panel 1. It is subtracted by the dimension S minus the width dimension W of 5. From the viewpoint of dispersion of expansion and contraction stress due to thermal expansion and contraction of the panel main bodies 1a and 2a due to temperature difference, it is preferable that the extension dimension E of the covering material 1b of the first panel 1 is set to about 50 to 300 mm. The dimension S excluding the covering material 2b of the panel 2 is set to a dimension obtained by subtracting the dimension W because the width dimension W of the gap 5 is about 0.5 to 3 mm as described above.

  The first panel main body 1a and the second panel main body 2a are of the same type, made of wood plywood, metal or concrete or reinforced concrete, or a flat plate obtained by laminating plates of the above materials, In this embodiment, a panel made of plated steel sheet is used. The panel body 1a, 2a is formed with a known fixing portion (not shown) for fixing to the arm 8, and as described above, the panel body 1a, 2a is attached to the arm 8 with a known fixing means such as a bolt, a nut or a screw. It is fixed.

  The covering materials 1b and 2b attached to the surfaces of the first panel main body 1a and the second panel main body 2a are of the same type, such as a synthetic resin such as a soft vinyl chloride resin or an olefin resin, or rubber. A long sheet having a thickness of about 1 to 3 mm, which is flexible enough to be wound up and rolled up, is preferably used. The covering materials 1b and 2b are attached to the panel main bodies 1a and 2a by the first adhesive 3 in advance at the factory and are shipped.

  The first adhesive 3 for adhering the covering materials 1b and 2b to the panel main bodies 1a and 2a strongly adheres the covering materials 1b and 2b and the panel main bodies 1a and 2a. The one that is volatilized and hardens is used. For example, one-component moisture-reactive urethane adhesives, two-component mixed-type reactive epoxy adhesives, one-component moisture-reactive modified silicone adhesives, solvent-evaporating rubber adhesives, etc. Well, a one-component moisture-reactive urethane adhesive that can firmly adhere the coating material and the panel body is particularly preferably used. When this first adhesive 3 is applied to the surface of the panel body 1a, 2a, the weight of the adhesive 3 is appropriate, and the reaction gas generated from the first adhesive 3 For the purpose of releasing the pressure of the solvent gas contained in the first adhesive 3 and preventing the swelling of the surfaces of the covering materials 1b and 2b, the first adhesive is used by using a comb iron (not shown). It is preferable to apply the adhesive 3 in a comb shape.

  As shown in FIG. 2, the region of the covering material 1 b that is attached to the first panel body 1 a with the first adhesive 3 is extended and located on the second panel body 2 a. The second panel main body 2a is adhered by a second adhesive 4 that is more flexible than the first adhesive 3.

The second adhesive 4 that is more flexible than the first adhesive 3 has a 50% tensile stress (50% modulus) of 0.1 to 1.5 N / mm ² , preferably 0.1 to 0.1%. 0.75 N / mm ² (the second adhesive 4 of this embodiment is 0.2 N / mm ² ) The tensile elongation at break is about 50 to 1000%, preferably 300 to 800% (of this embodiment The second adhesive 4 is 650%), and the conditions are such as a one-part moisture-reactive modified silicone adhesive, a one-part moisture-reactive urethane adhesive, and a polysulfide adhesive. In this embodiment, a one-component moisture-reactive modified silicone adhesive is used as the second adhesive 4.

  The 50% tensile stress (50% modulus) is obtained by placing a 2 mm thick spacer with the central part cut into a rectangle on the second adhesive 4 and a non-adhesive flat plate, and removing the rectangular part. Pour the second adhesive 4 into the surface, slide the leveling tool over the spacer to remove the unnecessary second adhesive 4 and leave it under the environment of temperature 20 ± 3 ° C. and humidity 50 ± 10%. After curing for 1 day, the spacer and the flat plate are removed to prepare a sheet of the second adhesive 4 having a thickness of 2 mm. Then, a dumbbell-shaped No. 1 type tensile test sample specified by JIS K 6251 is cut out from the adhesive sheet, and this sample is subjected to a tensile test (tensile speed: 100 mm / min) at a temperature of 20 ±. Under an environment of 3 ° C. and humidity of 50 ± 10%, 50% tensile stress was measured according to JIS A 1439.

  The tensile elongation at break is determined by tensile testing the sample with a tensile tester (tensile speed: 100 mm / min) and tensile rupture according to JIS K 6251 in an environment of temperature 20 ± 3 ° C. and humidity 50 ± 10%. The elongation was measured.

  The flexible second adhesive 4 having such characteristics is applied with a substantially uniform thickness (so-called solid coating). When the second adhesive 4 is applied in this manner, the seal of the seam 6 is applied. Even if the agent 7 is damaged and water enters between the covering materials 1b and 2b and the panel main bodies 1a and 2a, there is no water channel, so the waterproofness is high.

  Moreover, for the same reason as the application of the first adhesive 3 for adhering the covering materials 1b and 2b in advance, the second adhesive 4 may be applied using a comb-shaped iron. When the sealing material 7 of the seam 6 of the covering materials 1b and 2b subjected to waterproofing is damaged and water enters, the concave line of the comb formed by the comb-shaped iron becomes a water channel, and the water becomes the covering material 1b. , 2b and the panel main bodies 1a, 2a, the comb direction is preferably applied in parallel with the seam 6. As described above, when the second adhesive 4 is applied using a comb-shaped iron, the comb-shaped ridges formed by the comb-shaped iron are deformed so as to fall to the left and right, and the stress is dispersed. Is also preferable.

  When the extended portion of the covering material 1b of the first panel 1 is adhered to the second panel body 2a by the flexible second adhesive 4 having the above characteristics, the panel is subjected to thermal expansion / contraction due to temperature difference or the like. Even if the width dimension W of the gap 5 between the main bodies 1a and 2a fluctuates, the stretching stress generated at that time is adhered by the flexible second adhesive 4 and the second adhesive 4 The coating on the gap 5 between the panel bodies 1a and 2a is distributed without being concentrated only on the coating 1b positioned just above the gap 5 by being dispersed throughout the coating area of the applied coating 1b. There is no need to worry about swelling of the material 1b, whitening or cracking.

  As shown in FIG. 2, the covering material 1b end edge of the first panel 1 and the covering material 2b end edge of the second panel 2 are formed so that the seam 6 when they are abutted is V-shaped. It has been excised. The joint 6 of the covering materials 1b and 2b is sealed with a sealant 7.

  The sealing agent 7 that seals the joint 6 of the coating materials 1b and 2b is a filler such as a one-component moisture-reactive modified silicone filler, a two-component mixed epoxy filler, or a coating with the coating materials 1b and 2b. A sealing liquid in which a soluble resin (vinyl chloride resin if the covering materials 1b and 2b are vinyl chloride resins) is dissolved in a solvent, and the sealing agent 7 is filled in the seam 6 so that the covering material 1b is filled. , 2b seam 6 is waterproofed, and problems such as the ends of the covering materials 1b, 2b rising up can be prevented. When sealing the joint 6 of the covering materials 1b and 2b, the excess sealant 7 protruding from the joint 6 is removed with a waste cloth or the edges of the covering materials 1b and 2b are masked in advance. Then, the sealant 7 may be filled into the joint 6 and the masking may be peeled off after the filling to remove the unnecessary sealant 7.

  The seam 6 of the covering materials 1b and 2b can be sealed by welding in addition to the sealing agent 7 as described above. The welding of the seam 6 of the covering materials 1b and 2b is performed by irradiating the seam 6 with heat such as hot air to melt the covering materials 1b and 2b of the seam 6 portion, while being compatible with the covering materials 1b and 2b. It is performed by filling a seam 6 formed in a V shape while melting a welding rod such as resin. At this time, the welding resin which has oozed out and becomes unnecessary may be removed with a cutter or the like.

  The floor structure using the floor assembly panel of this embodiment uses two floor assembly panels 1 and 2, but the number of floor assembly panels is not only two, but is increased in number and assembled. be able to. In that case, the relationship between the first panel 1 and the second panel 2 can be dealt with by placing the relationship between the second panel 2 and the third panel (not shown). Further, the relationship between the first panel 1 and the second panel 2 can be set to the relationship between the third panel and the second panel 2. In other words, the first panel 1 with the extended covering material 1b may be assembled in order, or separately, the covering material on both sides of one panel may be provided, or conversely on both sides. An extended covering material may be provided.

  The effect confirmation test of the floor structure using the floor assembly panel having the above configuration was conducted. This effect confirmation test was carried out for 1 day after assembling in an environment with a temperature of 5 ° C. using floor assembling panels 1 and 2 having panel bodies 1a and 2a made of plated steel plates of 0.68 m × 1.8 m as longitudinal grips. After curing, leave it at 50 ° C for 1 day. Next, after leaving at 5 ° C. for 1 day, it is left at 50 ° C. for 1 day. Although this cycle test was conducted 5 cycles, no abnormality such as swelling, whitening or cracking occurred in the covering materials 1b and 2b.

  FIG. 3 is a cross-sectional view showing a main part of a floor structure using a floor assembly panel according to another embodiment of the present invention.

In the floor structure using the floor assembly panel according to this embodiment, the flexible second adhesive 4 is also filled in the gap 6 between the first panel 1 and the second panel 2. It is.
The other structure of the floor structure using the floor assembly panel according to this embodiment is the same as the floor structure using the floor assembly panel according to the embodiment shown in FIGS. A description will be omitted with reference numerals.

  In the floor structure using the floor assembly panels 1 and 2 as described above, the flexible second adhesive 4 is filled in the gap 5 provided between the panel bodies 1a and 2a. Even if water enters between the panel main bodies 1a, 2a and the covering materials 1b, 2b, the water is stopped by the flexible adhesive 4, so that the first panel 1 and the second panel 1 Waterproofing between the panels 2 is ensured.

  FIG. 4 is a cross-sectional view showing a main part of a floor structure using a floor assembly panel according to still another embodiment of the present invention, and FIG. 5 is an explanatory view showing a method for forming the floor structure shown in FIG. .

  The floor structure using the floor assembly panel shown in FIG. 4 includes an end portion on the second panel 2 side of the first panel main body 1a and a covering material 1b of the first panel 1 located above the first panel body 1a. In other words, the region where the second adhesive 4 is applied is extended to the first panel 1 side by the dimension E1.

The extension dimension E1 (that is, the distance from the end of the first panel body 1a on the second panel 2 side to the first adhesive 3 applied to the first panel body 1a) is 10 to 200 mm. It is preferable that the second adhesive 4 is flexible, and the second adhesive 4 is flexible on both sides of the gap 5 between the panel bodies 1a and 2a. 4 is formed, the stretching stress generated when the width dimension W of the gap 5 between the panel bodies 1a and 2a fluctuates is dispersed on both sides of the gap 5, and the stress relaxation effect is further improved. The covering material 1b is not adversely affected. Moreover, since the 2nd adhesive agent 4 is what is apply | coated at a construction site, the area | region which applies the 2nd adhesive agent 4 is extended to the 1st panel 1 side (namely, 1st adhesive agent 3). The coating region 1b of the first panel 1 can be lifted to apply the second adhesive 4 and the gap 5 between the panel bodies 1a and 2a can be applied. Also, the flexible second adhesive 4 can be filled easily.
Since the other structure of the floor structure using the floor assembly panel of this embodiment is the same as the floor structure using the floor assembly panel of the embodiment shown in FIG. 3 described above, the same reference numerals are assigned to the same members. Therefore, the description is omitted.

  The floor structure using the floor assembly panel according to the present embodiment extends the region where the second adhesive 4 is applied to the first panel main body 1a, so that the above-described covering material by dispersion of the stretching stress is applied. The effect of preventing the swelling and breakage of 1b becomes more prominent.

  Next, a method for forming a floor structure using the floor assembly panel of this embodiment will be described.

The floor structure using the floor assembly panel of this embodiment can be formed by the following procedure. First, as shown in FIG. 5A, the first adhesive 3 is applied to the surface of the first panel main body 1a, and is extended to the second panel 2 side by the extension dimension E. The first covering 1 is produced by pasting the coated covering material 1b. At this time, as described above, the region of the extension dimension E1 from the end of the first panel body 1a on the second panel 2 side is refrained from applying the first adhesive 3. Then, the second panel body 2 a is prepared by pasting the covering material 2 b subtracted by the subtracting dimension S with the first adhesive 3. Next, as shown in FIG. 5B, a gap 5 is provided between the panel main bodies 1a and 2a by the width dimension W to fix the floor assembling panels 1 and 2 to the brace 8. While applying the 2nd adhesive agent 4 to the area | region where the 1st adhesive agent 3 of 1a, 2a surface is not apply | coated, the 2nd adhesive agent 4 also to the gap | interval 5 between panel main body 1a, 2a. As shown in FIG. 5C, the covering material 1b of the first panel 1 is attached to the region where the second adhesive 4 is applied. And as shown in FIG.5 (d), the floor structure using the panel for floor assembly which has the outstanding effect mentioned above is completed by sealing the joint 6 of the coating | covering materials 1b and 2b with the sealing agent 7. FIG. To do.
In the present embodiment, the seam 6 is cut in a V shape in advance, but it goes without saying that the V-shaped seam 6 may be formed immediately before the sealing agent 7 is filled and sealed.

  The floor structure using the floor assembly panel of the embodiment shown in FIG. 4 can be formed more easily by using the floor assembly panel sets 10 and 2 described below.

That is, as shown in FIG. 6, this floor assembly panel set 10, 2 includes a first panel 10 in which a covering material 10b is extended to the second panel 2 side, and a first panel 10 of the covering material 2b. The covering material 10b of the first panel 10 has a dimension S obtained by subtracting the covering material 2b of the second panel 2 and the first panel 10 and the first panel 10. It is formed to be longer than the dimension obtained by adding the width dimension W of the gap 5 between the panel bodies 1a and 2a provided when the two panels 2 are arranged. In other words, the covering material 10b of the first panel 10 of this embodiment is further extended to the covering material 1b of the first panel 1 of the above-described embodiment by an extension dimension E2. When arranged, they overlap with the covering material 2b of the second panel 2. The extension dimension E2 is preferably set to about 5 to 150 mm in consideration of workability.
The other structure of the floor assembly panel set 10, 2 is the same as the floor assembly panel 1, 2 of the floor structure using the floor assembly panel of the embodiment shown in FIG. The same reference numerals are given and description thereof is omitted.

In order to form a floor structure using the floor assembly panel sets 10 and 2 as described above, as shown in FIGS. 7A and 7B, the first panel 10 and the second panel 2 are connected. Then, a gap 5 is provided between the panel main bodies 1a and 2a and fixed to the arm 8, and the covering material 10b of the first panel 10 is overlaid on the covering material 2b of the second panel 2, and the overlapping portion is formed. Both the covering materials 10b and 2b are cut by the cutting tool 9 at the desired joint formation place 6a, and the cut pieces are removed from both the covering materials 10b and 2b. At this time, since the cut piece of the covering material 2b of the second panel 2 is stuck to the second panel main body 2a by the first sticking agent 3, the first sticking using a peeling tool such as a scraper. It is necessary to remove from the panel body surface together with the adhesive 3. Then, as shown in FIGS. 7C and 7D, the flexible second adhesive 4 is applied to the surface of the panel bodies 1a and 2a (the area where the first adhesive 3 is not applied). ), The gap 5 between the panel main bodies 1a and 2a is filled with the second adhesive 4 and the coating material 10b of the first panel 10 is applied to the application area (the first adhesive 4). It is completed by sticking to the panel main body 1a and the second panel main body 2a) and finally sealing the new seam 6 where the covering materials 10b, 2b face each other with the sealant 7.
Since the other method of forming the floor structure using the floor assembly panel sets 10 and 2 of this embodiment is the same as that of the embodiment shown in FIG. 5 described above, the same members are denoted by the same reference numerals. Description is omitted.

The floor assembly panel sets 10 and 2 as described above and a method of forming a floor structure using the floor assembly panel set 10 and 2 extend the covering material 10b of the first panel 10 more than the covering material 1b of the first panel 1 described above. By extending further by the dimension E2, when the gap 5 is provided and fixed to the arm 8, the further extended portion of the covering material 10b of the first panel 10 becomes the covering material of the second panel 2. It will overlap with 2b. By cutting the overlapping portions of the covering materials 10b and 2b with a cutting tool 9 such as a cutter, the ends of the covering materials 10b and 2b can be perfectly matched, and the seam 6 can be processed cleanly. As a result, good waterproof properties can be secured. Further, when the floor structure is formed using such floor assembly panel sets 10 and 2, assembly errors of the panels of the floor assembly panel sets 10 and 2 and the covering materials 10b and 2b to the panel main bodies 1a and 2a. Even if there is a sticking error, the workability is very good because the error can be adjusted when cutting the covering materials 10b and 2b.
To supplement this point, paradoxically, in the floor assembly panels 1 and 2 of the above-described embodiment, the extension dimension E of the covering material 1b is set according to the assembly plan of the floor assembly panels 1 and 2. However, there may be a gap between the edges of the covering materials 1b and 2b due to assembly errors of the panels 1 and 2, and in such a case, the edges of the covering materials 1b and 2b cannot be properly sealed. There is a risk that rainwater or the like may enter between the covering materials 1b and 2b and the panel main bodies 1a and 2a. Therefore, it is necessary to reassemble the floor assembling panels 1 and 2 or to close the gap with another narrow covering material at the gap between the edges of the covering materials 1b and 2b. It will be. The present embodiment using the floor assembly panel sets 10 and 2 can solve the above-mentioned problems and can be said to be extremely preferable.

  FIG. 8 is a cross-sectional view showing a main part of a floor structure using a floor assembly panel according to still another embodiment of the present invention.

  The floor structure using the floor assembling panel of the embodiment shown in FIG. 8 has an end portion on the second panel 2 side of the surface of the first panel main body 1a and the covering of the first panel 1 positioned above the end portion. While the material 1b is stuck by the 2nd sticking agent 4, the edge part by the side of the 1st panel 1 of the coating | covering material 2b of the 2nd panel 2, and the 2nd panel main body 2a located in the downward direction However, it is stuck with the second sticking agent 4. That is, the area where the second adhesive 4 is applied is extended to the first panel 1 side by the extension dimension E1, and the covering material 1b of the first panel 1 and the second panel 2 It extends from the joint 6 with the covering material 2b toward the second panel 2 by an extension dimension E3.

The extension dimension E3, which is the distance from the joint 6 of the covering materials 1b and 2b to the first adhesive 3 applied to the second panel body 2a, is set to a range of about 10 to 200 mm. If the area where the second adhesive 4 is applied is extended in this range, the width dimension W of the gap 5 between the panel bodies 1a and 2a varies due to thermal expansion and contraction due to temperature difference, for example, the first Even when the extended covering material 1b of the panel 1 is pulled in the direction of the gap 5 between the panel bodies 1a and 2a, the end portion of the concealed covering material 2b of the second panel 2 However, since the stress can be dispersed, the load of the tensile stress on the sealant 7 of the joint 6 is reduced, and the joint 6 having a relatively low strength is not damaged. Moreover, the coating material 2b of the second panel 2 is rolled up to facilitate the application of the second adhesive agent 4, and the second adhesive agent 4 can be applied to the coating material 2b without performing a masking process or the like. Since it does not adhere to the surface, workability is high.
Since the other structure of the floor structure using the floor assembly panel of this embodiment is the same as the floor structure using the floor assembly panel of the embodiment shown in FIG. 4 described above, the same reference numerals are assigned to the same members. Therefore, the description is omitted.

  In the floor structure using the floor assembly panel of the embodiment shown in FIG. 8, the area where the second adhesive 4 is applied is applied to the first panel body 1 a and the covering material 2 b of the second panel 2. By extending each of the above, the effect of preventing the swelling and breakage of the covering materials 1b and 2b due to the dispersion of the stretching stress described above becomes even more remarkable.

  FIG. 9 is a cross-sectional view showing a main part of a floor structure using a floor assembly panel according to still another embodiment of the present invention.

As shown in FIG. 9, the floor structure using the floor assembly panel of the present embodiment has an upper end side on the second panel 2 side of the surface of the first panel main body 1a and a second surface of the second panel main body 2a. A cut surface is provided on the upper end side on the one panel 1 side to form a recess 1c. The recess 1c is formed by chamfering, rounding, or bending the surface end of the panel main bodies 1a and 2a facing each other, or bending into a crank shape and having a depth of about 2 mm and a width of about 2 mm. It is preferable to form the recess 1c by providing a cut surface within the range. The concave portion 1c can also be obtained by providing it in either one of the panel main bodies 1a and 2a. However, since the concave portion 1c serves as an adhesive agent reservoir for the second adhesive agent 4, both panel main bodies are provided. More preferably, the recess 1c is formed by cutting out 1a and 2a.
Since the other structure of the floor structure using the floor assembly panel of this embodiment is the same as the floor structure using the floor assembly panel of the embodiment shown in FIG. 8 described above, the same reference numerals are assigned to the same members. Therefore, the description is omitted.

  In the floor structure using the panel main bodies 1a and 2a in which the recesses 1c as described above are formed, when the second adhesive 4 is applied to the panel main bodies 1a and 2a, the second adhesive 4 naturally becomes the panel. The gap 5 between the main bodies 1a and 2a is filled, and waterproofing can be easily performed. Moreover, by filling the concave portion 1c with the second adhesive 4 as well, the thickness of the layer to which the second adhesive 4 is applied is increased, and the layer of the second adhesive 4 is not easily damaged. Therefore, there is a remarkable effect that waterproofness is further improved.

  Further, the floor structure of the embodiment shown in FIG. 9 can also be formed by using the floor assembly panel sets 10 and 2 having the extension dimension E2 as in FIG. 6 described above.

That is, in order to form the floor structure shown in FIG. 9, as shown in FIGS. 10A and 10B, the first panel 10 and the second panel 2 are placed between the panel bodies 1a and 2a. The gap 5 is provided and fixed to the arm 8, and the covering material 10b of the first panel 10 is overlaid on the covering material 2b of the second panel 2, and both covering materials 10b and 2b in the overlapping portion are overlapped. Cutting is performed by the cutting tool 9 at the desired joint formation place 6a, and the cut pieces are removed from both the covering materials 10b and 2b. At this time, unlike the embodiment shown in FIG. 7 described above, the end portion (the portion of the extension dimension E3) of the covering material 2b of the second panel 2 is not attached by the first adhesive 3. In addition, if the joint formation place 6a is positioned in the application area of the second adhesive 4 (the area where the first adhesive 3 is not applied), a peeling tool such as a scraper becomes unnecessary. Workability is further improved. Next, as shown in FIGS. 10C and 10D, a flexible second adhesive 4 is applied to the surface of the panel bodies 1a and 2a, and the gap 5 between the panel bodies 1a and 2a. And the recess 1c is filled with the second adhesive 4. At this time, unlike the embodiment shown in FIG. 7 described above, the second adhesive 4 is also provided below the covering material 2b of the second panel 2 (region where the first adhesive 3 is not applied). Note the application. Then, the covering material 10 b of the first panel 10 is adhered to the application region of the second adhesive 4, and the covering material 2 b of the second panel 2 is adhered to the application region of the second adhesive 4. Finally, the new seam 6 in which both the covering materials 10 b and 2 b are abutted is finally sealed with the sealant 7.
Since the other method of forming the floor structure using the floor assembly panel sets 10 and 2 of this embodiment is the same as that of the embodiment shown in FIG. 7, the same reference numerals are assigned to the same members. Description is omitted.

  When the floor structure using the floor assembly panel shown in FIG. 9 is formed by the above method, the covering material 2b of the second panel 2 can be rolled up and the second adhesive 4 can be applied, and masking or the like can be performed. Since the second adhesive 4 does not adhere to the surface of the covering material 2b without performing the above treatment, the load of the tensile stress on the sealing agent 7 of the seam 6 can be easily reduced and compared. It is possible to form a floor structure that does not cause the seam 6 having a low mechanical strength to break, and the workability is extremely high.

  FIG. 11 is a cross-sectional view showing a main part of a floor structure using a floor assembly panel according to still another embodiment of the present invention, and FIG. 12 is a floor assembly having the extension dimension E2 similar to FIG. It is explanatory drawing which shows the method of forming using a panel set.

In the floor structure using the panel for floor assembly according to this embodiment, the covering material 1b of the first panel 1 is extended to the second panel 2 side, and the covering material 2b of the second panel 2 is connected to the second structure. A predetermined gap C is formed between the edge of the covering material 1b of the first panel 1 and the edge of the covering material 2b of the second panel 2 when the end on the one panel 1 side is subtracted. . In other words, the second dimension is obtained by subtracting the width dimension W of the gap 5 from the dimension obtained by adding the gap C between the edges of both the covering materials 1b and 2b to the extending dimension E of the covering material 1b of the first panel. The covering material 2b of the panel 2 is subtracted. Then, a flexible second adhesive 4 is filled in the gap C between the edges of the covering materials 1b and 2b in place of the sealing agent 7 described above.
When the second adhesive 4 filling the gap C is applied in advance to the surface of the panel main body 1a, the second adhesive 4 is applied more than an appropriate amount, and the covering materials 1b and 2b are applied to the panel main body 1a. , 2a may be used to overflow the second adhesive 4 and fill the gap C. After the covering materials 1b, 2b are attached to the panel bodies 1a, 2a, the gap C is separately provided. May be filled.

The width dimension W1 of the gap C formed between the edge of the covering material 1b of the first panel 1 and the edge of the covering material 2b of the second panel 2 is about 1 to 10 mm (more preferably 2 to 5 mm). It is preferable to set the If the width dimension W1 is smaller than 1 mm, the filling amount of the second adhesive 4 is insufficient, and the edges of the covering materials 1b and 2b may be raised, and the width dimension W1 is more than 10 mm. If it is large, there is a problem that a considerable amount of the second adhesive 4 is required and the cost is increased. Therefore, the width dimension W1 of the gap C is preferably set within the above range.
Since the other structure of the floor structure using the floor assembly panel of this embodiment is the same as the floor structure using the floor assembly panel of the embodiment shown in FIG. 9 described above, the same reference numerals are assigned to the same members. Therefore, the description is omitted.

  In addition to the effect of the floor structure shown in FIG. 9 as described above, the floor structure using such a panel for panel assembly also uses the second adhesive 4 filled in the gap C so that the panel bodies 1a and 2a are mutually connected. Since the expansion and contraction stress generated by the fluctuation of the width dimension W of the gap 5 between them is relieved, the covering materials 1b and 2b on the gap 5 between the panel bodies 1a and 2a are swollen or whitened or cracked. As a matter of course, there is no concern that the edges of both the covering materials 1b and 2b are swollen, and the waterproofness is further improved.

  A floor structure using the above-described floor assembly panel can also be formed using the above-described floor assembly panel set 10, 2 shown in FIG.

That is, in order to form the floor structure using the floor assembly panel sets 10 and 2 having the extension dimension E2 as in FIG. 6, as shown in FIGS. The panel 10 and the second panel 2 are fixed to the arm 8 by providing a gap 5 between the panel bodies 1a and 2a, and the covering material for the first panel 10 is placed on the covering material 2b for the second panel 2. 10b are overlapped, and the covering material 1b of the first panel 1 and the covering material 2b of the second panel 2 in the overlapping portion are cut at two places with a predetermined gap width dimension W1, and both covering materials are cut. A predetermined gap C is formed between the edges 1b and 2b, and the cut pieces are removed from both the covering materials 10b and 2b. Next, as shown in FIGS. 12C and 12D, a flexible second adhesive 4 is filled into the gap 5 and the recess 1c of the panel bodies 1a and 2a, and the panel bodies 1a and 2a are filled. The 2nd adhesive agent 4 is apply | coated to the surface of this, and the coating | covering material 10b of the 1st panel 10 and the coating | covering material 2b of the 2nd panel 2 are stuck. And the floor structure using the panel for a floor assembly shown in FIG. 11 is completed by filling the gap | interval C of the edge of both coating | covering materials 1b and 2b with the 2nd adhesive agent 4. FIG.
Since the other method of forming the floor structure using the floor assembly panel sets 10 and 2 of this embodiment is the same as that of the embodiment shown in FIG. 10, the same reference numerals are assigned to the same members. Description is omitted.

When forming the floor structure using the panel for floor assembly by the above method, the second sticking of an amount larger than an appropriate amount in advance (that is, an amount in anticipation of the second filler 4 for filling the gap C). The coating agent 4 is applied to the surface of the panel main bodies 1a and 2a, and both the covering materials 1b and 2b are pressed against the panel main bodies 1a and 2a to be adhered, so that the second adhesive 4 is naturally applied to both the covering materials. Since the gap C between the end edges of 1b and 2b is filled, a highly waterproof floor structure can be formed very easily.
Needless to say, the second adhesive 4 protruding from the gap C may be removed by wiping off afterwards.

  As described above, the floor structure using the floor assembly panels of various embodiments has been described in detail from FIGS. 1 to 12. However, in any embodiment of the floor structure, the covering materials 1b (10b) and 2b Since it is possible to prevent swelling, whitening, and cracks from occurring, it may be arbitrarily selected in consideration of the shape of the balcony.
