  Hereinafter, a roof panel 100 having a sandwich structure according to an embodiment for carrying out the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the roof panel 100 according to the present embodiment includes a back material 104, an organic layer 108 (heat insulating layer), a surface material 102, and a soft polyvinyl chloride sheet 122 (waterproof sheet). And a laminated structure.

  The surface material 102 is made of a thin plate-like body, and is made of, for example, a rectangular thin plate-like body having a length in the long direction of 250 to 1200 cm and a length in the short direction of 60 to 100 cm. The material of the surface material 102 is, for example, a metal such as iron, aluminum, copper, or stainless steel, or an alloy made of a combination thereof. The surface material 102 may be various steel plates such as, for example, a color galvalume steel plate, an aluminum / zinc alloy plated steel plate, an enamel steel plate, a clad steel plate, and a laminated steel plate. For example, in this embodiment, a galvalume steel plate is used. The surface material 102 is formed by press forming, extrusion forming, roll forming, or the like. The thickness of the surface material 102 is, for example, 0.5 to 1.0 mm.

  The surface material 102 provides the roof panel 100 with a predetermined bending strength, protects the roof panel 100 from the outside air, rain, wind, snow, and the like, and improves the weather resistance and impact resistance.

  The back material 104 constitutes the front and back surfaces of the surface material 102 and the roof panel 100, and the organic layer 108 is laminated between them. The back surface material 104 is comprised from the thin plate-shaped object, for example, is comprised from the thin plate-shaped body whose length of the elongate direction is 300-1250 cm and whose length of a short direction is 60-100 cm. Its material, molding method, and thickness are equivalent to the material, molding method, and thickness of the surface material 102.

  The back material 104 gives bending strength to the roof panel 100 similarly to the surface material 102.

  The organic layer 108 is formed between the front surface material 102 and the back surface material 104. A surface material 102 is attached to the upper surface of the organic layer 108 by adhesion or a joining metal fitting (not shown). Thereby, integration as the roof panel 100 formed by laminating the back material 104, the organic layer 108, the surface material 102, and the soft polyvinyl chloride sheet 122 is achieved.

  The organic layer 108 is formed of, for example, a phenol foam that is a phenol resin foam. In the present embodiment, Neomafoam (trade name) is used as the phenol foam of the organic layer 108.

  The soft polyvinyl chloride sheet 122 is formed by adding a plasticizer such as dioctyl phthalate to polyvinyl chloride, and has flexibility and waterproofness. When the soft polyvinyl chloride sheet 122 is heated to a temperature not lower than the melting point (for example, 150 ° C. to 200 ° C.) by a heating welder such as an electric iron in a state where the soft polyvinyl chloride sheet 122 is stacked, the sheets are stacked. The soft polyvinyl chloride sheets 122 are welded together to form an integral body. The shape of the soft polyvinyl chloride sheet 122 is rectangular like the surface material 102, the side A of the surface material 102 and the side a of the soft polyvinyl chloride sheet 122 are substantially parallel, and the side B of the surface material 102 The side b of the soft polyvinyl chloride sheet 122 is substantially parallel. The thickness of the flexible polyvinyl chloride sheet 122 is, for example, 1.5 to 2.5 mm. As shown in FIG. 3, the length of each side of the soft polyvinyl chloride sheet 122 is larger than the length of each corresponding side of the surface material 102. That is, when the length of the side A of the surface material 102 is compared with the length of the side a of the soft polyvinyl chloride sheet 122 corresponding thereto, the length of the side a is larger. Further, when the length of the side B of the surface material 102 is compared with the length of the side b of the soft polyvinyl chloride sheet 122 corresponding thereto, the length of the side b is larger.

  The soft polyvinyl chloride sheet 122 is bonded to the surface of the surface material 102 in the region S3 (FIG. 3) with an organic adhesive such as an epoxy resin adhesive. The region S3 is in the vicinity of the center portion of the surface material 102, and is separated from all sides of the surface material 102 by a predetermined distance (for example, 4 cm to 8 cm). Since the surface bonding is used as the bonding method in the region S3, the bonding force is stronger than the point bonding. For example, the soft polyvinyl chloride sheet 122 is peeled off from the surface material 102 when a strong wind blows. Can be suppressed. Adhesion between the soft polyvinyl chloride sheet 122 and the surface material 102 is performed at the stage of manufacturing the roof panel 100 before the roof panel 100 is carried into a construction site (construction site). Therefore, it is not necessary to affix all the surfaces of the soft polyvinyl chloride sheet 122 to the surface material 102 at the construction site, and the construction period can be shortened at the construction site while maintaining the strength of the adhesive force by the surface adhesion. In addition, the amount of work at the construction site can be reduced.

  As shown in FIG. 3, the soft polyvinyl chloride sheet 122 is not bonded over the entire surface material 102, but the soft polyvinyl chloride sheet 122 is formed on the peripheral portion (region other than the region S <b> 3) of the surface material 102. It is not bonded and is bonded to the surface material 102 in the region S3. The lengths of D1 and D2 are each 4 cm or more, and the area (area other than the area S3) where the soft polyvinyl chloride sheet 122 is not bonded in the surface material 102 is the roof panel 100 (see FIG. 5). This is a space for installing the screws 126 and the like (FIG. 5) used for fixing to the etc.

  Further, a part of the soft polyvinyl chloride sheet 122 is not bonded to the surface material 102, and when comparing the length of D1 and the length of d1, the length of d1 is larger, and the length of D2 and the length of d2 Compared with the length, the length of d2 is larger. That is, the area of the soft polyvinyl chloride sheet 122 that is not bonded to the surface material 102 (S2) is the area of the surface material 102 that is not covered with the soft polyvinyl chloride sheet 122 and exposed (S1). ) Larger than the area. Hereinafter, in the present specification, “exposed” means that the surface material 102 is not covered with a waterproof function, and the form covered with a layer having a function other than the waterproof function is “exposed”. Shall be included. In the present embodiment, the shape of S1 is L-shaped.

  As described above, the roof panel 100 having the sandwich-type structure realizes improvement in workability and improvement in waterproof performance while maintaining waterproof performance and shortening the construction period at the construction site.

  Hereinafter, an embodiment of the assembly process of the roof panel connection structure 120 will be described with reference to FIG. In practice, many roof panels 100 are connected to form a roof panel connection structure, but only two roof panels 100 are shown in FIGS. 4 and 5 for simplicity of the drawings.

  First, a plurality of roof panels 100 are laid on the same plane on the base material 124 and fixed using screws 126 (FIG. 4A). At this time, the plurality of roof panels 100 are combined and laid on the base material 124 so that the uneven portion 109 becomes a fitting portion (joint portion). Next, the adjacent soft polyvinyl chloride sheets 122 are overlaid (FIG. 4B). Thereafter, the soft polyvinyl chloride sheet 122 is heated to a temperature equal to or higher than its melting point (for example, 150 ° C. to 200 ° C.). ), The overlapping portions of the soft polyvinyl chloride sheet 122 are welded to form an integrated soft polyvinyl chloride sheet (FIG. 4C).

  In this way, the roof panel connection structure 120 (FIG. 5) can be assembled.

  As described above, the area of the soft polyvinyl chloride sheet 122 that is not bonded to the surface material 102 (S2) is not covered with the soft polyvinyl chloride sheet 122 of the surface material 102 and is exposed. It is larger than the area of the region (S1). As shown in FIGS. 4A and 4B, when the roof panel connection structure 120 is assembled, the area (S1) that is not covered with the soft polyvinyl chloride sheet 122 and exposed is another roof panel. It is covered with a region (S2) of 100 soft polyvinyl chloride sheets 122. Since the area of S2 is larger than the area of S1, when the soft polyvinyl chloride sheet 122 is welded by heat, it is soft on the peripheral part (area other than the area S3) of the surface material 102 where the screw 126 is installed. Although the polyvinyl chloride sheet 122 is not adhered, the surface material of the roof panel connection structure 120 is covered without gaps by the soft polyvinyl chloride sheet 122 in an integrated shape, so that the roof panel connection structure 120 is highly waterproof. Sex is maintained.

  As described above, the adhesion between the soft polyvinyl chloride sheet 122 and the surface material 102 can be performed at the stage of manufacturing the roof panel 100 before the roof panel 100 is carried into the construction site (construction site). it can. Therefore, it is not necessary to affix all the surfaces of the soft polyvinyl chloride sheet 122 to the surface material 102 at the construction site, and the construction period can be shortened at the construction site while maintaining the strength of the adhesive force by the surface adhesion. In addition, the amount of work at the construction site can be reduced.

  As described above, the roof panel connecting structure 120 with high waterproof performance is realized while realizing the shortening of the construction period at the construction site and the improvement of workability.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible. For example, in the present embodiment, the configuration has been described in which the peripheral portions of the two sides of the surface material 102 are not covered with the soft polyvinyl chloride sheet 122, but only one side of the surface material 102 is soft as shown in FIG. It is exposed without being covered with the polyvinyl chloride sheet 122, and at least one side of the surface material 102, the soft polyvinyl chloride sheet 122 is separated from the one side of the surface material 102 by a predetermined distance, and corresponds to the one side. It is only necessary that one side of the soft polyvinyl chloride sheet 122 is substantially parallel and the area of S2 is larger than the area of S1.

  In the present embodiment, the embodiment using the soft polyvinyl chloride sheet 122 as the waterproof sheet has been described. However, the flexible polyvinyl chloride sheet 122 has flexibility and waterproofness, and is bonded to the surface material 102 with an adhesive and is welded by heating. Any soft waterproof sheet can be used. For example, a soft polyethylene sheet or a soft polyolefin sheet may be used. The welding temperature and the welding time are appropriately set depending on the material of the waterproof sheet.

  Moreover, in this embodiment, although the organic layer 108 was used as a heat insulation layer, and the form which used Neomafoam (trade name) as the organic layer 108 was demonstrated, what has a heat insulation performance should just be mentioned, for example, phenol urethane or Other phenolic foams such as phenol foam, extruded foamed polystyrene foam, rigid urethane foam, and various foamed plastics such as PVA (polyvinyl alcohol) and PP (polypropylene) may be used.

  In the present embodiment, the organic layer 108 that is a heat insulating layer is sandwiched between the front surface material 102 and the back surface material 104, but fire resistance performance is provided between the back surface material 104 and the organic layer 108. In order to increase the temperature, a flame-retardant inorganic layer may be sandwiched. As the material of the inorganic layer 106, for example, a gypsum board, a calcium silicate plate, a calcium carbonate plate, or the like is used. The thickness of the inorganic layer 106 is 7-21 mm, for example.
