Description

  The present invention relates to a solar panel scattering prevention device and a solar panel installation structure. More specifically, the present invention relates to the prevention of scattering of solar panels installed at an interval from the roof.

  The roof of a building is often empty, whether it is an existing building or a new building. This is because, in order to ensure the required waterproof performance, the building is lightened, and the seismic force acting on heavy objects is high at a high position from the ground. In recent years, there have been an increasing number of cases where lightweight solar panels are installed on the roof due to requests such as effective use of empty space on the roof and effective use of clean energy.

  However, for example, in an existing building, it is not easy to appropriately install a solar panel on the roof (on the roof) while maintaining the required waterproof performance. This is because the wind power is strong on the roof and the wind flow is disturbed on the outer periphery of the building, so that large wind power acts on the solar panels installed at an interval from the roof.

  If the solar panel is not properly installed, the wind power can cause the solar panel to scatter and fall and damage itself. In addition, there is a risk that the scattered and dropped solar panels may collide with people.

  The present invention has been made in view of the above-described problems, and provides a scattering prevention device that can reliably prevent solar panels installed at intervals from the roof from being scattered due to the influence of wind. The purpose is to do.

In order to solve the above-mentioned problem, in the first embodiment of the present invention, a solar panel scattering prevention device installed at an interval upward from the roof,

The deck plate includes an upper flange, a lower flange body positioned below the upper flange, an inclined web extending obliquely from the upper flange to the lower flange body, and the upper flange from both ends of the lower flange body. An anti-scattering device having an end flange extending obliquely upward to a height position is provided.

  According to a second aspect of the present invention, there is provided a solar panel installation structure characterized by comprising the scattering prevention device of the first aspect.

  In the anti-scattering device of the present invention, for example, an end-closed deck plate is attached close to the lower surface of the solar panel, so that the upper surface is flat as a whole and the lower surface is integrated with a convex shape. A downward force is applied to the solar panel and deck plate by the passing wind. As a result, according to the present invention, it is possible to reliably prevent the solar panels installed with a space upward from the roof from being scattered due to the influence of the wind.

The deck plate 1 is positioned so that the pair of side flanges 1e are placed on the upper end surfaces of the corresponding engaging members 12a. Next, the lower support member 12c is positioned so that the bolt portions of the bolts and nuts 12e protruding upward from the pair of side flanges 1e of the deck plate 1 pass through the holes formed in the lower support member 12c. The lower support member 12 c is placed on the upper surfaces of the pair of side flanges 1 e of the deck plate 1.

  Next, the solar panel 11 is positioned with respect to the plurality of lower support members 12c placed on the upper surfaces of the pair of side flanges 1e of the deck plate 1 with the bolt portions of the bolts and nuts 12e penetrating therethrough. The solar panel 11 is placed on the support surface of the lower support member 12c. Further, the upper support member 12d is positioned so that the bolt portion of the bolt / nut 12e protruding upward from the lower support member 12c penetrates the hole formed in the upper support member 12d, and the plurality of upper support members 12d are contacted. The solar panel 11 is sandwiched between the contact surface and the support surfaces of the plurality of lower support members 12c.

  Finally, the nut of the bolt / nut 12e (not shown in FIG. 5) is screwed into the bolt portion of the bolt / nut 12e protruding upward from the upper support member 12d and tightened. Thus, as shown in FIGS. 6 and 7, the deck plate 1, which is a main component of the scattering prevention device according to the present embodiment, is attached to the roof in the state of being close to the lower surface 11 a of the solar panel 11.
