Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure incorporating a photovoltaic power generation panel, and more particularly to a roof structure having good workability and capable of improving the appearance design of the roof.

[0002]

2. Description of the Related Art In recent years, roof structures incorporating photovoltaic power generation, which is clean energy, have been used to improve the global environment.

As a roof structure incorporating such photovoltaic power generation, for example, those shown in FIGS. 8 and 9 are typical.

[0004] First, the construction procedure shown in Fig. 8 is as follows. A concave mounting bracket (b) is fixed on a cemented flat roofing material (a), and a vertical rail (b) is inserted into a concave portion of the mounting bracket (b). c) Insert and fix. To the vertical rail (c), attach the horizontal rail mounting bracket (d) provided with a concave part for the horizontal rail (e) (in the figure, C-type channel) receiver on the upper side,
The horizontal rail (e) is mounted on the horizontal rail mounting bracket (d). Then, the photovoltaic power generation panel (f) is fixed to the crosspiece (e) by cover materials (g) and (h).

[0005] On the other hand, the one shown in Fig. 9 has a wooden vertical bar (c ') fixed in the vertical direction (in the direction of one eave) on a roof foundation (i) having roofing applied on a base board. Then, a horizontal rail (e ') (C type channel in the figure) is constructed on top of it, and a cover material
Attach photovoltaic panel (f) using (g) and (h).

The former is also referred to as a gantry system. However, since the gantry for supporting the photovoltaic power generation panel is formed on the roof finishing material such as the existing flat roof material with vertical and horizontal crosspieces, the former is considerable. As well as heavy equipment, the appearance of the solar power generation device on the roofing material will be very much. In addition, there is a problem that workability and workability are not good because the installation work is performed on the existing roofing material.

In the latter method, the photovoltaic power generation panel itself is used as a roof finishing material as compared with the former method, so that the feeling of discomfort when placed on the roof material is reduced.
Since the flat tempered glass surface of the photovoltaic power generation panel is simply arranged in a row, the appearance is poor and noppelled, and there is a problem that there is no sense of luxury and poor decorativeness.

Further, when the roof slope is steep, the glass surface is slippery, so that there is a problem that sufficient attention must be paid to the work.

[0009]

Therefore, in a roof structure incorporating a photovoltaic power generation panel, there is no sense of incongruity that a photovoltaic power generation device is mounted on a roofing material, and the roof has a rich three-dimensional appearance. There is a demand for a roof structure that can make constructions appear and that can perform construction work more safely and efficiently.

A horizontal rail that has a smaller thickness in the height direction than the horizontal rail (52) that fixes the lower end of the solar panel as a horizontal rail to be fixed
A step portion is formed by using (51).

According to this, a step is formed in the solar power generation panel connected vertically by using the horizontal rails having different thicknesses in the height direction, so that a decorative and rich three-dimensional appearance can be exhibited on the roof. it can. The horizontal rails that fix the lower end of the photovoltaic power generation panel have a large thickness in the height direction, and the horizontal rails that fix the upper end have a smaller thickness in the height direction. Since the slope of the photovoltaic power generation panel is gentler than that, the construction work can be performed more safely and efficiently.

The roof structure incorporating the photovoltaic panel according to claim 5 is the roof structure according to claim 1, claim 2, claim 3 or claim 4, wherein the frame (7) )
Is provided with a ventilation portion (10) for securing ventilation inside and outside the panel.
