Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tiled roof in which a solar cell is integrated with a roof structure.

[0002]

2. Description of the Related Art When solar cells are installed on the roof of a house,
Conventionally, a gantry is mounted on a roofing material such as a tile and a solar cell is fixed to the gantry.

[0003] However, in such a structure, the solar cells protrude above the roof, making the appearance unsightly. In addition, when the solar cell is installed from the beginning of the construction of the house, the solar cell mounting portion is similar to other roofs. Since the installation work of the solar cell must be newly performed after the roofing work, there is a drawback that the construction period is long, and the number of members is large and the cost is high. Moreover, such an increase in the number of members is not preferable in terms of waterproofing,
There is a problem with safety even in a typhoon.

Therefore, in order to solve such a problem,
Conventionally, on a general roof part, a piece of wood is fixed on a field board and a general tile material is installed to raise the general roof part, and the solar cell installation part is a metal sheet roofing steel sheet laid on the field board. It has been considered that the roof can be installed with a commercially available solar cell so that there is no step between the general roof and the solar cell installation roof (see Utility Model Registration No. 3026979). ).

[0005]

However, in the case of a metal-plated roof, it is not enough to simply lay the metal-plated roof plate on the field board and nail it, and then the end of each roof plate will have sufficient rain and strength. There is a disadvantage that it is not.

[0006] Further, as described above, in a structure in which a special stand and a module holder are attached on a roofing plate to fix a frame of a commercially available solar cell, four steps are required, and the number of working steps is reduced. The number of parts increases, and the cost increases. Such a method is a work in which the construction of the roof and the construction of the solar cell are completely separated, and in any case, it is an uneconomical construction method.

[0007] In view of the above, the present invention combines a roof structure with a tiled roof and a solar cell module to provide a solar cell with excellent rain performance and strength, and reduced construction steps and the number of parts. It is intended to provide a roof structure provided with a roof.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a roofing plate constituting a metal-plated roof. Covering and fixing the tile bar cap to the roof structural material, and fixing both ends of the solar cell module to the tile bar cap.

In the above description, the tile rod cap may be composed of a pair of frame members divided along the roof inclination direction.
