Description

The present invention uses a mating roofing material, particularly a heat insulating material, which is widely used for roofs of general houses, offices, condominiums, welfare facilities, resort facilities, etc. as a core material, and sandwiches the core material between the outer skin material and the endothelial material. It relates to a mating type roofing material having a laminated structure.

A roofing material having a laminated structure in which a core material forming a heat insulating layer is sandwiched between an exodermis material and an endothelial material has high heat insulating performance, is lightweight, and has high strength, durability, and sound deadening property. Demand tends to increase.

In such a fitting type roofing material, the roofing materials are connected in the girder direction by fitting the upper goby provided at the end of one roofing material to the lower goby provided at the end of the other roofing material. It is common to roof the roof together.

By the way, in the conventional fitting type roofing material, in a state where the roofing materials are joined to each other, the roofing materials are continuous between the end faces of the roofing materials along the thickness direction according to the deformation of the working width of the roofing materials. As shown in the above, a gap t may occur, and there is a problem that the heat insulating characteristics inherent in the roofing material having a laminated structure cannot be effectively exhibited.

An object of the present invention is to propose a fitting type roofing material capable of connecting roofing materials to each other without creating a gap that causes a heat insulating defect.

The present invention is a roofing material having a contour shape partitioned by a pair of long edge portions extending along the beam-to-beam direction and a pair of short edge portions extending along the girder direction by sandwiching each of these long edge portions. It is provided with a main body and an upper goby and a lower goby that are integrally connected along each of the long edges of the roofing material main body.
Each of the short edges is superposed on the short edges of other roofing materials that are adjacent to each other on the underwater side and the waterside side of the roofing material body to connect the roofing materials in the beam-to-beam direction, while the upper haze, A fitting type roofing material that roofs a building structure by fitting the lower haze to the lower and upper haze of other roofing materials that are adjacent to each other in the girder direction and connecting the roofing materials in the girder direction. And
An endothelium that forms the outer surface of the roofing material main body and is arranged to face the outer skin material forming the upper goby and the lower goby at intervals on the back surface of the outer skin material to form the inner surface of the roofing material main body. It is provided with a material, a core material sandwiched between the exodermis material and the endothelial material, and forming a heat insulating layer.
The exodermis material is connected to the lower end of the lower goby, covers one end face in the width direction of the core material, and gradually protrudes toward the end face in the width direction of another roofing material adjacently arranged in the girder direction. Has a slanted descending wall
The endothelial material covers all or a part of the other end face in the width direction of the core material, and has an inclined rising wall that gradually rises to just below the upper goby toward the end face of another roofing material adjacently arranged in the girder direction. It is a fitting type roofing material characterized by having.

In the mating roofing material having the above configuration,
1) The inclined descending wall has a tongue piece at the lower end thereof, which is located on the same plane as the endothelial material and is fixed to the base material by driving a fixing means such as a screw or a drill screw.
2) It is preferable that the tongue piece has a rib that forms a hidden gutter in cooperation with the inclined descending wall as a specific means for solving the problem.

According to the present invention, the inclined descending wall provided on the outer skin material faces the inclined rising wall provided on another roofing material arranged adjacently, and the inclined rising wall provided on the endothelial material is arranged adjacently. Since it faces the sloping descending wall provided on the roofing material, even if there may be a gap between the end faces depending on the working width of the roofing material, along the thickness direction of the plate material body. No continuous gaps are formed, and the heat insulating performance is not significantly impaired.

Further, according to the present invention, even if rainwater or the like invades from the fitting portion of the roofing material, the invaded rainwater or the like can be efficiently discharged through a hidden gutter.
