  However, in the waterproof structure shown in the above-mentioned Patent Document 1, it is necessary to perform the construction first when the construction of the heat insulating material is required. there were.

  Moreover, in the waterproof structure shown by the said patent document 1, the bottom part of the corrugated panel as a board | plate material for construction is made into an edge part, the edge parts of the bottom part are piled up, and it is set as the junction part of corrugated panels, and the joining The synthetic resin sheet covering the joint is heat-sealed to the synthetic resin sheet on the surface of the corrugated panel on both sides, but in this structure there is a joint at the bottom where rainwater flows and collects, so the synthetic resin that covers the joint The synthetic resin sheet is likely to be peeled off or scratched by being exposed to a rainwater stream and sand or other foreign matters flowing in the sheet, and the synthetic resin sheet covering the joint is peeled off or scratched. In some cases, there was a problem that the water leaked immediately.

  Therefore, the present inventors have a waterproof structure that improves workability when construction of a heat insulating material is required, and a synthetic resin sheet that covers a joint portion between panels has less burden such as water flow, and the synthetic resin sheet. As a result of diligent research on a waterproof structure that does not easily lead to water leakage even when peeling or scratches occur, the waterproof structure and the waterproof structure panel of the present invention have been completed.

  That is, the waterproof structure for a building of the present invention uses a synthetic resin film laminated steel plate in which a synthetic resin film is laminated on the surface of a steel plate, sandwiches a heat insulating material between two steel plates, and at least outdoors of the two steel plates. Forming steel sandwich panels using the facing steel plates as the synthetic resin film laminated steel plates, adjoining the ends of the plurality of steel sandwich panels to each other, and stacking at least the steel plates facing the outdoors at the ends of each other In addition, the steel sandwich panels are joined to each other, and the overlapping portion of the steel sheets made of the synthetic resin film laminated steel sheet is covered with a waterproof sheet of the same material as the synthetic resin film in a watertight manner. Is.

  Further, another waterproof structure for a building of the present invention uses a synthetic resin film laminated steel plate in which a synthetic resin film is laminated on the surface of a steel plate, and protrudes toward the outdoors at least at an end of the synthetic resin film laminated steel plate. The steel plate panel is formed by providing a portion, the end portions of the plurality of the steel plate panels are adjacent to each other, and the protruding portions protruding toward the outdoors at the end portions are joined portions of the steel plate panels. In addition, the joint between the steel plate panels is water-tightly covered with a waterproof sheet made of the same material as the synthetic resin film.

  And the waterproof panel for buildings of the present invention that can be used in the former waterproof structure for buildings of the present invention uses a synthetic resin film laminated steel sheet in which a synthetic resin film is laminated on the surface of a steel sheet, and uses two steel sheets as a heat insulating material. A steel sandwich panel is formed by using, as the synthetic resin film laminated steel plate, at least a steel plate that is sandwiched between the two steel plates and that faces at least the outdoors.

  Further, the other waterproof panel for buildings of the present invention that can be used in the latter waterproof structure for buildings of the present invention uses a synthetic resin film laminated steel plate in which a synthetic resin film is laminated on the surface of a steel plate, and the synthetic resin film laminate A steel plate panel is formed by providing a protrusion projecting outward at least at an end of the steel plate.

  According to the former waterproof structure for a building of the present invention, a steel sandwich panel in which a heat insulating material is sandwiched between two steel plates is used, and at least one of the two steel plates facing the outdoors is a synthetic resin on the surface. Since it is a synthetic resin film laminated steel plate that covers the surface by laminating films, the steel sandwich panel is mounted side by side with the synthetic resin film laminated steel plate facing the outside at a predetermined position on the roof or wall of the building. , Because it is possible to construct roofs and walls containing insulation just by water-tightly covering the overlapping part of the steel plates at the end of the steel sandwich panel with a waterproof sheet, when construction of insulation is required The workability can be greatly improved as compared with the prior art. In addition, by integrally configuring the base material, the heat insulating material, and the waterproof material, it is possible to easily ensure quality while improving the construction speed.

  Therefore, according to the former waterproofing structure for buildings of the present invention, a waterproof roof having the same level as that of a general waterproofing method can be efficiently constructed. In addition, since the waterproof material is laminated on the steel plate, the waterproof material can be thinned, and thus the amount of combustible material can be reduced, so that the incombustible performance can be improved. Further, since the waterproof material is laminated on the steel sheet as compared with the conventional waterproof sheet material, it is possible to prevent a situation where the waterproof performance of the roof is impaired due to the damage of the waterproof layer. And since the flat overlapping part of the steel plates at the end of the steel sandwich panel is covered with a waterproof sheet in a watertight manner, the waterproof sheet has little burden of water flow etc., and the waterproof sheet is peeled off or scratched etc. But it can be made difficult to leak.

  In the former waterproofing structure for buildings of the present invention, the synthetic resin film laminated steel sheet at one end of the two adjacent ends of the steel sandwich panel is lowered and the other end is The synthetic resin film laminated steel sheet may be protruded from the heat insulating material and overlapped on the synthetic resin film laminated steel sheet with the one end lowered, and in this way, between the steel sandwich panels The surface of the joint can be flattened.

  Moreover, in the former waterproofing structure for buildings of the present invention, a groove is formed in the heat insulating material at one end of the two adjacent ends of the steel sandwich panel. Each of the steel sheets is folded into the groove, and a protrusion that fits into the groove is formed in the heat insulating material at the other end, and the two steel sheets at the other end are respectively formed along the protrusions. And the other end portion of the steel plate and the other end portion of the steel plate may be overlapped with each other by fitting the protruding portion of the other end portion into the groove portion of the one end portion. If it makes it, in addition to being able to make the surface of the junction part of steel sandwich panels flat, steel sandwich panels can be temporarily fixed mutually.

  Furthermore, in the former waterproofing structure for a building of the present invention, the steel sandwich panel is bent toward the end face side of the heat insulating material by projecting the respective steel plates at the two adjacent end portions from the heat insulating material, The bent steel plates may be butted together and overlapped, and in this way, in addition to being able to flatten the surface of the joint between the steel sandwich panels, the end of the butted steel plate The steel sandwich panels can be temporarily fixed by holding the portion with the channel member.

  On the other hand, according to the latter waterproof structure for a building of the present invention, a synthetic resin film laminated steel plate is used in which a synthetic resin film is laminated on the surface of the steel plate and the surface is covered, and at least the end of the synthetic resin film laminated steel plate is used. Since the steel plate panels are formed by providing protrusions that protrude toward the outside, the steel plate panels are mounted side by side with the synthetic resin film facing the outdoors at the predetermined position where the roof or wall of the building is provided. Since roofs and walls including heat insulating material can be constructed simply by covering the joints between steel plate panels, which are projections projecting outdoors, with a waterproof sheet, the workability can be greatly improved compared to conventional ones. . In addition, by integrally configuring the base material and the waterproof material, it is possible to easily ensure the quality while improving the construction speed.

  Therefore, according to the latter waterproofing structure for buildings of the present invention, a waterproof roof at the same level as that of a general waterproofing method can be efficiently constructed. In addition, since the waterproof material is laminated on the steel plate, the waterproof material can be thinned, and the amount of combustible material can be reduced thereby improving the incombustible performance. Further, since the waterproof material is laminated on the iron plate as compared with the conventional waterproof sheet material, it is possible to prevent a situation in which the waterproof performance of the roof is impaired due to the damage of the waterproof layer. And since the joints between the steel plate panels, which are protrusions projecting outdoors, are watertightly covered with a waterproof sheet, the waterproof sheet has less burden such as water flow, and the waterproof sheet has been peeled off or scratched. Even in cases, it can be difficult to lead to water leakage.
