Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure of a building such as a house in which solar cells are installed.

[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.

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 is considered that a roof is provided with a solar cell thereon so that a step is not formed between a general roof section and a solar cell installation roof section (see Utility Model Registration No. 3026979).

[0005]

However, in the above-mentioned conventional apparatus, in the general roof part, a piece of wood is installed on a base plate and a tile base material is further installed. There is a drawback that the number of members increases and the number of work steps also increases.

The present invention solves such conventional disadvantages and greatly increases the number of members and the number of work steps while having a structure in which a solar cell installation portion does not protrude significantly from a general roof portion. The purpose of the present invention is to provide a low-cost roof structure that does not have any problems.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a general roof portion on which a roofing material such as a tile is installed. While lowering, the roofing material is laid on the main roof on a main roof via a roofing board, and the solar cell is also installed on the solar cell installation section via a roofing board and a metal sheeting material, The solar cell is characterized in that it does not protrude more than a general roof.
