[Mounting method using mounting bracket]
A method of attaching the panel 5 (the first panel 5a and the second panel 5b) to the crosspiece 7 of the frame 6 using the mounting bracket 10 described above will be further described with reference to FIG.

The panel 5 has a structure in which a plurality of cells are sandwiched between resin or tempered glass, and the outer periphery is reinforced with an aluminum alloy frame 51 . The surface of the frame 51 is treated with an insulating alumite in order to prevent the appearance from deteriorating.

The pedestal 6 has a structure in which crosspieces 7 arranged in a grid pattern are connected to the upper part of support piles driven into the ground. Among the plurality of crosspieces 7 assembled in a parallelepiped shape, the upper crosspiece called the upper crosspiece is defined as a crosspiece 75, and the lower crosspiece called the crosspiece is defined as a crosspiece 76. . A panel 5 is attached to the upper surface of the crosspiece 75 .

As shown in FIG. 6(a), when the first panel 5a is placed on the top surface of the crosspiece 75 of the mount 6, the mounting bracket 10 is positioned at the position where the frame 51a of the first panel 5a and the crosspiece 75 intersect. It becomes the mounting position to be used. The same applies to the second panel 5b and subsequent panels. In FIGS. 6A and 6B, the mounting position on the first panel 5a is indicated by a solid line circle, and the mounting position on the second panel 5b is indicated by a broken line circle.

First, as shown in FIG. 6(a), the first panel 5a is attached to the upper surface of the cross member 75 in a temporarily tightened state. Specifically, the fitting groove 211 of the crosspiece contacting portion 21 of the clamp member 2 is fitted into the return portion 72 at the tip of the upper flange portion 71 extending outward from the upper portion of the crosspiece 75 . Thereby, the clamp member 2 is engaged with the crosspiece 75 .

In this state, the clamp nut member 3 is arranged so that the frame contact portion 31 contacts the upper surface of the frame 51a, and the fastening member 1 is temporarily tightened (see FIG. 5(c)).

When the panel 5 is attached to the crosspiece 75 at a plurality of locations, the same operation is performed at each attachment position, and the first panel 5a is temporarily attached to the crosspiece 75 using a plurality of mounting brackets 10 .

After all the mounting brackets 10 are temporarily tightened, the bolts as the fastening members 1 are sequentially tightened one by one with a predetermined torque to fix the first panel 5a to the crosspiece 75 . At this time, the rising portions 43a and 43b in contact with the lower surface of the frame 51a are pressed against the frame 51a to damage the insulating alumite layer, and the panels 5 attached to the frame 6 are electrically connected to each other.

Next, as shown in FIG. 6(b), the second panel 5b is attached to the upper surface of the crosspiece 75 in the same manner as the first panel 5a. However, when arranging the clamp nut member 3, the first contact portion 33 and the second contact portion 34 are arranged so as to contact the side surfaces of the frames 51b and 51a of the adjacent second panel 5b and first panel 5a, respectively. Deploy.

Similarly, as shown in FIG. 6(c), a plurality of panels 5 are attached to the crosspiece 75. Then, as shown in FIG.

FIG. 6(d) shows a state in which only one panel 5 is removed. As described above, the mounting bracket 10 is configured so that the frame contact portion 31 can contact only one of the two adjacent panels 5, so that the two adjacent panels 5 can be attached to each other like a conventional panel clamp. When replacing one panel 5 of the panels 5, it is not necessary to remove the other panel 5 together. Moreover, since the mounting bracket 10 can be used in the same way for the end panel 5 where there is no adjacent panel 5, there is no need to separately prepare a mounting bracket dedicated to the end panel 5. - 特許庁

As described above, according to the mounting bracket 10 of the present embodiment, the crosspiece contact portion 21 of the clamp member 2 is brought into contact with the crosspiece 75, and the frame contact portion 31 of the clamp nut member 3 is brought into contact with the panel. After contacting the frame 51 of 5, the fastening member 1 can be inserted and fastened from the crosspiece 75 side. Therefore, even when the panel 5 is attached to a tall frame 6 such as a farming type solar panel, the fastening work can be performed from the crosspiece 75 side, so that work efficiency can be improved. As described above, the mounting bracket 10 is extremely excellent in workability when mounting the panel 5 to the frame 6 .

Further, according to the mounting bracket 1 of the present embodiment, the clamp member 3 can be fitted to the crosspiece 75 not at a pinpoint but in a wide area, and the clamp nut member 3 can be fitted to the frame 51. The frame 51 can be clamped by abutting not on a pinpoint but on a wide area. Therefore, the panel 5 can be stably attached to the pedestal 6 .

At the end panel 5, a maximum of two mounting brackets 10 can be used for mounting positions. Specifically, in addition to the position where the mounting bracket 10 is used, the mounting bracket 10 can also be used at the position indicated by "P" on the opposite side of the crosspiece 75 as shown in FIG. In this case, it goes without saying that the mounting bracket 10 has a symmetrical structure with respect to the vertical plane passing through the longitudinal center line of the crosspiece 75 as the symmetrical plane from the structure shown in FIGS. By attaching the panel 5 to the crosspiece 75 using the two mounting brackets 10, the attachment strength can be increased, and thus the durability against heavy loads such as snow accumulation and strong winds can be enhanced.

The embodiments described above are described to facilitate understanding of the present invention, and are not described to limit the present invention. Therefore, each element disclosed in the above embodiments is meant to include all design changes and equivalents that fall within the technical scope of the present invention.

Instead of using the earth plate 4, the mounting bracket 10 may be electrically connected using another member. Further, the shape of the rising portion 44a and the rising portion 44b can be appropriately changed according to the shape of the mounting bracket 10 as a whole. Alternatively, the mounting bracket 10 may be configured so as not to provide the conductive function without providing the rising portions such as the rising portions 44a and 44b.
