As a result, the mounting bracket 1 of the present embodiment is suitable for using the intersecting position as the mounting position in a state where the crosspiece 71 of the gantry 7 and the frame 61 of the photovoltaic power generation panel 6 are arranged so as to intersect with each other. It has a shape.

A method of mounting the photovoltaic power generation panel 6 on the crosspiece 71 of the gantry 7 by using the mounting bracket 1 described above will be described with reference to FIG.

The photovoltaic power generation panel 6 has a structure in which a plurality of cells arranged are sandwiched between resin, tempered glass, or the like, and the outer periphery is reinforced by a frame 61 made of an aluminum alloy. The surface of the frame 61 is anodized with insulating properties in order to prevent deterioration of the aesthetic appearance. On the back side of the frame 61 (opposite side of the condensing surface 62 on which the cells are arranged), as shown in FIG. 3 (c), inside so that the frame 61 can be stably placed on the crosspiece 71 of the gantry 7. A flange-shaped backside flange portion 611 extending toward the surface is formed.

The gantry 7 has a structure in which a crosspiece 71 assembled in a grid shape is connected to the upper part of a support pile cast on the ground, and is a crosspiece located on the upper side of the crosspiece 71 assembled in a grid shape. The photovoltaic power generation panel 6 is attached to the upper surface of the so-called cross member 71.

As shown in FIG. 3A, the solar power generation panel 6 is placed on the upper surface of the crosspiece 71 of the gantry 7, and the frame 61 surrounding the outer periphery of the solar power generation panel 6 intersects with the crosspiece 71 of the gantry 7. The position to be used is the mounting position where the mounting bracket 1 is used.

First, as shown in FIG. 3B, the fitting groove 31 of the clamp member 3 is fitted into the return portion 712 at the tip of the flange portion 711 extending outward in the upper part of the crosspiece 71. The clamp member 3 is engaged with the crosspiece 71.

In this state, as shown in FIG. 3C, the clamp nut member 5 has the frame contact portion 51a and the frame contact portion 51b (or the frame contact portion 51c and the frame contact portion 51d) on the lower side of the frame 61. Arrange the lower flange portion 611 so as to be in contact with the upper surface of the flange portion 611 and sandwich the lower flange portion 611 between the clamp nut member 5 and the ground plate 4, and temporarily tighten the bolt 2. At this time, the ground plate 4 is narrowly provided between the clamp member 3 and the clamp nut member 5 so that the rising portions 43a and 43b of the ground plate 4 abut on the lower surface of the lower flange portion 611. ..

When mounting a plurality of locations of the photovoltaic power generation panel 6 on the crosspiece 71, perform the same work at each mounting position, and temporarily fasten the photovoltaic power generation panel 6 to the crosspiece 71 of the gantry 7 using the plurality of mounting brackets 1. Install in the state.

After temporarily tightening all the mounting brackets 1, the bolts 2 are tightened one by one with a predetermined torque to fix the photovoltaic power generation panel 6 to the crosspiece 71 of the gantry 7. At this time, the rising portions 43a and 43b of the ground plate 4 that are in contact with the lower surface of the lower flange portion 611 are pressed against the lower flange portion 611, thereby damaging the insulating alumite layer and being attached to the gantry 7. The solar power generation panels 6 of the above are electrically connected to each other.

As described above, in the present embodiment, the fitting groove 31 of the clamp member 3 is fitted into the crosspiece 71, the clamp nut member 5 is arranged on the photovoltaic power generation panel 6 side, and the frame of the clamp nut member 5 is arranged. The back side flange portion 611 of the frame 61 of the photovoltaic power generation panel 6 is sandwiched between the contact portion 51a and the frame contact portion 51b (or the frame contact portion 51c and the frame contact portion 51d) and the clamp member 3. When such a mounting bracket 1 is used, when the photovoltaic power generation panel 6 is attached to a tall pedestal 7 such as a farming type solar, it is not from the photovoltaic power generation panel 6 side but from the crosspiece 71 side of the pedestal 7.
