Description

  The present invention relates to a mounting structure for installing a solar cell solar cell on a goby type folded plate roof, and in particular, prevents a positional deviation of the solar cell module and the mounting bracket due to a snow load loaded on the roof or the solar cell array. The present invention relates to a solar cell module mounting structure of a goby type folded plate roof.

  In a solar cell, the “cell” is the basic unit of the solar cell and refers to the solar cell element itself. The “module” is a panel of resin or tempered glass that can be used outdoors by arranging multiple cells. It has become. The “module” is generally called a solar cell panel, and a state in which a plurality of modules are arranged and continuous is called an “array”.

  When installing a solar cell on the existing roof, after constructing a mount on the roof, a plurality of solar cells are arranged on the upper surface. The platform in this case is formed in advance in the size of the array, and there are a case where a plurality of modules are arranged thereon, a case where a plurality of platforms for modules are installed, and a case where each module is installed on each platform. In either case, since a pedestal to be built on the roof is required, the weight of the pedestal increases and there is an inconvenience of placing a large burden on the roof.

  On the other hand, there is a goby-type folded-plate roof that is used as a factory roof and has a large area. This goby-type folded-plate roof is constructed by connecting roof plates in which mountain parts and valley parts are alternately bent, and a connecting goby is provided on the top of the mountain part. Attention has been focused on a mounting structure for installing the device (see Patent Documents 1 and 2).

  The mounting structure described in Patent Document 1 is a structure in which a stand for a solar cell module is constructed by using a fixing bracket that sandwiches a goby from the side. In this way, by using the fixing metal fitting that sandwiches the goby, it is not necessary to open the screw hole for the gantry in the roof plate, and rain leakage can be prevented.

  The mounting structure described in Patent Document 2 is a structure in which a receiving bracket is connected to the upper surface of a fixing bracket that sandwiches a goby, and a side edge portion of a solar cell module is directly fixed to the receiving bracket. Like this mounting structure, the load on a roof can be reduced in weight by using a receiving bracket instead of a mount.

Japanese Utility Model No. 2012-102543 JP 2012-167456 A

  In the mounting structure described in Patent Document 1, a pedestal for a solar cell module is constructed. Therefore, it is necessary to assemble a support frame for the pedestal on the fixing bracket in a cross-beam shape. For this reason, there is an inconvenience that the weight of the gantry increases. When installing solar cells on the roof, the snow load on the roof becomes a problem, especially in snowy areas, so a lighter mounting structure is suitable. Therefore, when using the attachment structure using the mount which increases weight like patent document 1 in a snowfall area, the problem that reinforcement of a roof is needed arises.

  On the other hand, as in Patent Document 2, according to the structure in which a receiving bracket is attached to the upper surface of the fixing bracket that sandwiches the goby and the solar cell module is directly connected to the receiving bracket, it can be fixed only with the fixing bracket and the receiving bracket Compared to the structure for constructing the gantry, the weight is extremely light and the load on the roof is very small.

  Generally, when installing a solar cell module in a snowfall area, the solar cell module is installed on the assumption of strength to withstand a snow load that accumulates snow on the solar cell module. However, according to the inventor's research, as in Patent Document 2, when a solar cell module is connected and installed on a goby folding plate roof using a fixing metal fitting or a receiving metal fitting, due to snow on the goby folding plate roof, It has been found that there is a possibility that the solar cell module may be damaged due to a displacement in the fixing metal clamping position or a shift between the receiving metal fitting and the solar cell module.

  That is, as shown in FIG. 5, in the goby type folded-plate roof P, goby P1 is provided along the inclination of the roof. Therefore, when there is snowfall, the snow on the solar cell array and the snow on the roof around the solar cell array are integrated and connected, and when the snow around the solar cell falls off the roof, It has been confirmed by experiments that a dragging action occurs.

  According to this experiment, as a result of an unexpected tensile load applied to the snow load that has accumulated on the module, the fixing brackets are displaced, and the intervals between the modules constituting the solar cell array are widened. It was found that the module was dropped.

  Therefore, the present invention was created to solve such problems specific to snowfall areas, and while maintaining the weight reduction on the roof, it has a strength that can withstand a snow load + a tensile load that has not been assumed so far. An object of the present invention is to provide a solar cell module mounting structure having a goby type folded plate roof.

  In order to achieve the above-mentioned object, the first means in the present invention is to support the solar cell module M by attaching to the upper surface of the fixing metal fitting 10 that sandwiches the goby P1 of the goby type folded plate roof P.

  The fixing bracket 10 of the second means includes a pair of sandwiching bodies 11 for sandwiching the seam P1 of the seam-type folded plate roof P from both sides, and a connecting bolt 12 for connecting the sandwiching bodies 11 to each other. The connecting bolt 12 is configured to connect the longitudinal end portion of the connecting fitting 30 to the connecting bolt 12.

  The receiving member 20 of the third means is connected to a fixing bolt 13 protruding upward from the upper surface of the fixing member 10, and a mounting tool 21 for mounting the side edge portion of the solar cell module M, and the mounting tool 21. A fixing tool 22 that engages on a side edge portion of the solar cell module M placed on the mounting tool 21 and is screwed to the mounting tool 21, and connects the side edge portions of the solar cell module M. It was configured as follows.

  The connection fitting 30 of the fourth means is formed with bolt insertion holes 31 connected to the connection bolt 12 of the fixing fitting 10 at both longitudinal ends thereof, and the bolt insertion holes 31 in the longitudinal direction of the goby P1. Is a ruler indicating the mounting position of the fixture 10 for fixing the solar cell module M.

  According to the first aspect of the present invention, the strip-shaped connecting metal fitting 30 arranged along the longitudinal side surface of the goby P1 is provided, and the fixing metal fittings 10 adjacent to each other along the longitudinal direction of the goby P1 are connected by the connecting metal fitting 30. By doing so, the structure is light and can withstand snow load + tensile load. And since the connection metal fitting 30 has comprised the strip | belt-plate shape along the goby P1, this connection metal fitting 30 exists in the state which is hard to receive the resistance at the time of snowfall moving on a roof. Therefore, the connection fitting 30 can effectively increase the connection strength of the fixing fitting 10 without being affected by snow accumulation.

  As in claim 2, the fixing bracket 10 includes a pair of sandwiching bodies 11 that sandwich the goby P <b> 1 of the goby folding plate roof P from both sides, and a connecting bolt 12 that connects the sandwiching body 11. Since the connecting bolt 12 is configured to connect the longitudinal end portion of the connecting fitting 30 to each other, the fixing fittings 10 are integrated by the connecting fitting 30. As a result, the fixing brackets 10 that support the solar cell modules M are integrated to produce an effect of strongly supporting the solar cell array.

  As in claim 3, the receiving bracket 20 is connected to a fixing bolt 13 protruding upward from the upper surface of the fixing bracket 10, and a mounting tool 21 for mounting a side edge of the solar cell module M; A fixing tool 22 that engages on the side edge of the solar cell module M placed on the mounting tool 21 and is screwed to the mounting tool 21, and connects the side edges of the solar cell module M. By having comprised so, the solar cell module M can be connected easily.

  According to a fourth aspect of the present invention, the connection fitting 30 is formed with bolt insertion holes 31 connected to the connection bolt 12 of the fixing fitting 10 at both longitudinal ends thereof, and the bolt insertion in the longitudinal direction of the goby P1. Since the interval between the holes 31 is provided with a standard function indicating the mounting position of the fixing bracket 10 for fixing the solar cell module M, the connecting bracket 30 increases the connection strength of each fixing bracket 10, and Since it can utilize as a ruler at the time of installing each fixing bracket 10, the installation operation | work of the fixing bracket 10 can be simplified and the installation process of the solar cell module M can be rationalized.
