Abstract

PROBLEM TO BE SOLVED: To provide a structure in which a photovoltaic power generation module can be directly mounted on a plate roof without forming a base such as a bar and easily fixed.
SOLUTION: When mounting the outer frame 4 of the photovoltaic module 3 on the folded panel roof 2 of a building 11 such as a parking lot or a warehouse, the folded panel roof hanging on the outer frame 4 of the photovoltaic module 3 is provided. This is a structure in which a bird avoiding net 7 is stretched between mountain portions 6 connected to the open space S on the second valley portion 5.
The stretching method is such that a bird-avoidance net 7 is placed on the mountain 6 of the folded-plate roof so as to cover the space between the mountains 6, and a holding plate 8 for holding the net is placed on the net 7 so that it can be fixed with screws 9 or the like. I do.

Description

  The present invention relates to a structure for preventing birds from entering a narrow valley space formed below a solar power generation module installed on a folded roof of a building such as a parking lot or a warehouse.

  When installing a photovoltaic module with a large number of photovoltaic panels (cells) on the surface of the folded roof of the building, the upper surface of the folded roof to be installed has a large uneven surface that is bent into a large wavy shape. Therefore, it is difficult to install a planar photovoltaic module as it is. For this reason, conventionally, as shown in Patent Literature 1, it is a common practice to form a grid on a folded-plate roof and prepare the groundwork, and then fix the photovoltaic power generation module on the groundwork. Have been.

With this type of mounting structure, small birds can enter the narrow space formed below the installed PV modules from the valleys of the folded-plate roof or between the crossbars to form nests, or be moved by wind or the like. There was a structural drawback that scattered leaves and garbage tended to collect in the valley.
In such valleys where nests and leaves are accumulated, the roof material is likely to corrode, which causes problems such as rain leakage and damage due to the reduced strength of the roof material when subjected to strong winds. there were.
In addition, when leaves and garbage are wet by rain, they do not dry easily, and the moisture contained therein may damage circuits arranged on the back surface of the photovoltaic module.
At the time of installation, in the case of the conventional structure, it is difficult to significantly reduce the cost because the cross-section member cost and labor are required to assemble the base cross-section.

  The present invention has been made in view of the above-mentioned circumstances, and when mounting a solar power generation module on a folded roof of a building such as a parking lot or a warehouse, a solar power generation module to be installed on the folded roof. It provides a structure that prevents small birds from entering the elongated valley space formed in the lower space and prevents leaves and debris from accumulating, thereby preventing damage to roofing materials and adverse effects of solar power generation modules. is there.

  In order to solve the above problems, the present invention provides a structure in which an outer frame of a photovoltaic module is directly mounted on a folded plate roof of a building. This is a structure that prevents birds from entering the lower space of the photovoltaic module, where a bird-avoidance net is stretched between the mountains that connect to the open space on the part.

  The invention according to claim 2, wherein in the above configuration, the side of the bird-avoidance net hanging on the outer frame of the photovoltaic module is sandwiched between the peak of the folded-plate roof and the outer frame of the photovoltaic module. It was done.

The present invention is configured as described above, and when mounting a solar power generation module on a building such as a parking lot, a bird avoidance net stretched around the solar power generation module allows birds to enter the valley space of the folded plate roof. Infiltration was impossible, and large leaves and garbage were not allowed to enter, so that damage was not caused by rain leakage or strong wind due to corrosion.
In addition, in the present invention, since the photovoltaic power generation module is directly attached on the folded-plate roof, the base material and the assembling labor are omitted compared to the above-mentioned conventional structure, so that significant cost reduction is possible. Was.

An embodiment of the present invention will be described below with reference to the drawings.
In the present invention, as shown in FIGS. 1 and 2, when the outer frame 4 of the photovoltaic module 3 is mounted on the folded plate roof 2 of a building 11 such as a parking lot, the outside of the photovoltaic module 3 is attached. This is a structure in which a bird avoiding net 7 is stretched between hills 6 connected to open spaces S on valleys 5 of the folded-plate roof 2 hanging on the frame 4.
In the method of stretching, a bird avoiding net 7 is placed on the mountain 6 of the folded-plate roof so as to close the mountain 6, and a holding plate 8 for holding the net is placed on the net 7 and fixed with screws 9 or the like.

  Further, since it is not easy to fix the bird avoiding net 7 directly to the outer frame 4 of the photovoltaic module 3, as shown in FIG. The sides are sandwiched between the ridges 6 of the folded-plate roof 2 and the outer frame 4 of the photovoltaic module, and the bolts 10 that stop the outer frame 4 when fixing the photovoltaic module 3 are used. Between the ridge 6 and the outer frame 4.

In FIG. 1, as an example of a structure in which the outer frame 4 of the photovoltaic module 3 is directly attached to the folded plate roof 2 of the building, the photovoltaic module 3 is fixed downward to the flange portion of the outer frame 4. A mode is shown in which a bolt is fitted into a hole provided in a mountain portion 6 of a folded-plate roof 2 of a parking lot, and a nut screwed from under the folded-plate roof 2 is rotated and fixed.
Also, as shown in FIG. 1, the end of the folded-plate roof 2 is usually closed with a blindfold, but dust finer than the mesh can be interposed between the blindfold and the wind and rainwater. Fall into the rain gutter from the gap provided in the roof, and are guided and discharged by the rain gutter, so that no garbage accumulates on the valley 6 of the folded plate roof 2.

In the present invention, a bird-avoidance net is installed between the mountains connected to the open space on the valley of the folded plate roof that hangs on the outer frame of the photovoltaic module of the building such as a parking lot or a warehouse, It is also possible to extend a bird-avoidance net over the entire surface of the folded plate roof under the photovoltaic module 3.
The present invention is also applicable to various structures other than parking lots and warehouses.

It is a perspective view of the present invention in a parking lot. It is the vertical side view which expanded the fixing | fixed part of the folding board roof and the outer frame which shows the stretched state of the bird avoidance net.
