Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting snow stoppers, and more particularly to a waterproof structure for a sloped roof in which a waterproof sheet is laid on a sloped roof base. It is a mounting structure of a snow stopper installed.

[0002]

2. Description of the Related Art A sloped roof such as a gabled roof or a ridge roof of a general house is constructed by, for example, tiled roofing, slate roofing, galvanized roofing, or the like. In terms of construction workability, etc., it is not always satisfactory.

In recent years, Japanese Patent Laid-Open Publication No. Sho 63-30
As disclosed in Japanese Patent No. 0158 and the like, a method of roofing using a waterproof sheet made of a soft synthetic resin is under study. Since such a sheet-roofed roof uses a waterproof sheet with a larger area than tiles and slate, the area that can be constructed at one time is increased, and improvement in construction workability can be expected. Since the fitting waterproof sheets can be joined to each other in a watertight state, the wind resistance and the waterproofness can be expected to be improved.

[0004] On the other hand, in the case of a sloped roof, especially in an area with a lot of snow, a snow stopper is often provided at various places on the sloped surface in order to avoid falling snow. Conventional snow stoppers are compatible with construction methods such as tile roofing, slate roofing, and tin roofing, and are attached in such a manner as to be inserted into overlapping portions of roofing materials such as tiles and slate. Since the mounting portion is covered by the roof material, strength and waterproofness have been obtained by conventional construction methods such as tile roofing, slate roofing, and tin roofing. However, since the waterproof sheet has a large area, it is necessary to install the snow stopper directly on the sheet, but with the conventional mounting structure such as the shape and installation method of the snow stopper, the mounting part is not covered and the strength is not increased. And the waterproofness was insufficient.

Further, the waterproof sheet as described above is often required to have a three-dimensional appearance by forming an uneven shape on the surface from an aesthetic point of view. Simply attaching it does not correspond to the uneven shape,
Insufficient mounting strength and waterproofness.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a waterproof sheet for a sloped roof in which a waterproof sheet is laid on a sloped roof base. An object of the present invention is to provide a mounting structure for a snow stopper installed on a vehicle.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a waterproof structure for a sloped roof in which a waterproof sheet is laid on a sloped base of a roof, in which a snow stopper is mounted on the waterproof sheet.
