Next, an embodiment of the present invention will be described with reference to the drawings.

In the mounting structure of the embodiment shown in FIGS. 1 to 4, 1 is a metal plate-roofed roof, 2 is a standing seaming portion, and in this embodiment, the standing seaming portion 2 is extended in the roof inclination direction. And 3 is a rubber block, 4 and 4 are mounting hardware, 5 is a lower frame, 6 is an upper frame, and 7 is a solar cell module.

The rubber-like block 3 has a rectangular parallelepiped shape or a cubic shape, has a groove 8 on the lower surface as shown in FIG. 2 (b), and stands in the groove 8 as shown in FIGS. 3 and 4. By passing the ridge portion 2, the rubber-like block 3 is supported on the roof surfaces 9 on both sides of the standing ridge portion 2, and the standing ridge portion 2 extends the standing ridge portion 2. In the lateral direction orthogonal to the direction, that is, the horizontal direction orthogonal to the roof inclination direction, the positioning state is maintained in a neat or playful position.

In the present embodiment, the groove portion 8 is provided in a cross shape, but this can also be used for a metal plate-roofed roof having a standing seaming portion extending in the horizontal direction orthogonal to the roof inclination direction. Therefore, if such a combination is not considered, the groove portion may be provided in a single character shape.

Further, as shown in FIGS. 2 and 3, the rubber-shaped block 3 is provided with a hole 10 that is located at the cross-shaped intersection of the groove 8 and penetrates in the vertical direction, and the lower frame 5 is provided in the hole 10. A screw shaft 11 composed of a headed bolt for connecting the two is inserted and arranged so that the head portion 11a is facing down and the tip side is projected upward from the upper surface portion of the rubber-like block 3 so as to be in an upward retaining state. ing. Needless to say, the lower end of the screw shaft 11 is inserted so as not to interfere with the standing seaming portion 2 passed through the groove portion 8.

As shown in FIGS. 2 to 4, the mounting hardware 4 and 4 are provided on both sides of the rubber-like block 3 in the extending direction of the standing seaming portion 2, that is, in the roof inclination direction. Each mounting hardware 4 is provided with a pair of holding portions 4a, 4a, and the holding portions 4a, 4a are arranged so as to sandwich the standing roof portion 2 extending outward from the groove 8 of the rubber-like block 3 from both sides. Then, by tightening with the bolt 4b, the standing seaming part 2 is sandwiched and attached to the roof in a fixed state.

Then, these mounting hardware 4 and 4 are provided with stoppers 4c and 4c located in front of and behind the rubber-like block 3 in the extending direction of the standing roof portion 2, and the rubber-like blocks are provided by the front and rear stoppers 4c and 4c. 3 is held in a properly positioned state in the extending direction of the standing and seaming portion 2, that is, in the roof tilting direction, and the stoppers 4c and 4c are fixed to the front and rear surfaces of the rubber-like block 3 with screws 4d or the like. It is attached.

The lower frame 5 is supported on the rubber-like block 3 so as to extend in the direction in which the standing ridge portion 2 extends, and as shown in FIG. 1, the lower frame 5 is rubber-like by the screw shaft 11 provided in the rubber-like block 3. The upper frame 6 connected to the block 3 and oriented in the direction orthogonal to the lower frame 5 is supported on the lower frame 5, and the upper and lower frames 5 and 6 are connected to the screw hardware 12 at their intersections. The solar cell module 7 is attached to the upper frame 6 by a fixed metal fitting 13.

In the above mounting structure, the rubber-like block 3 is used, and the rubber-like block 3 is supported on the roof surfaces 9 on both sides of the standing portion 2 and is mounted on the rubber-like block 3 for mounting the solar cell module. Since the structure is such that the frame 5 is supported, the elasticity of the rubber-like block 3 makes it possible to form a dynamically stable mounting state.

Moreover, the rubber-like block 3 is held in a positioned state in the lateral direction orthogonal to the extending direction of the standing seaming portion 2 by the standing seaming portion 2 passed through the groove portion 8 on the lower surface portion, and the mounting hardware 4 The front and rear stoppers 4c and 4c of the mounting hardware 4 and 4 hold the stoppers 4c and 4c in the positioning state in the extending direction of the standing and seaming portion 2, and in such a positioning and holding state, the stoppers 4c and 4c of the mounting hardware 4 and 4 are rubber-like blocks 3 Since it is attached to the front and rear surfaces of the rubber with screws 4d ..., and each of the mounting hardware 4 and 4 is attached to the roof by sandwiching the standing seaming part 2. , It is possible to form a stable and firm mounting state.

If it is necessary to form a more secure mounting state, it is also possible to bond the rubber-like block 3 and the roof surfaces on both sides of the standing seaming portion 2 with an adhesive.

In addition, since each of the mounting hardware 4 and 4 is configured to be mounted on the metal plate roof by sandwiching the standing seaming portion 2, the metal roofing is used for mounting on the metal plate roof. It is not necessary to make holes in the board, so that the risk of water leakage can be eliminated.
