  As shown in FIG. 1, a solar cell module mounting bracket (an example of a fixture) 10 according to an embodiment of the present invention includes a solar cell module (an example of an installation) SP and a fitting portion (projection) 12. It can be attached to the formed roof plate 14.

As shown in FIGS. 2A and 2B, the solar cell module mounting bracket 10 includes an inner bracket 20 and an outer bracket 40 that is disposed so as to cover the outer side of the inner bracket 20. The inner metal fitting 20 and the outer metal fitting 40 are fastened by the fastening body 50.
The inner metal fitting 20 has the inner base part 202 and the clamping part 204 as shown in FIG. The inner base portion 202 and the sandwiching portion 204 are integrally formed by bending a single plate material.
The inner base portion 202 is disposed above the hull portion 12 and has a rectangular shape in plan view. A first hole H <b> 1 is formed in the central portion of the inner base portion 202. The first hole H1 is, for example, a square hole.

  The sandwiching portion 204 is formed at the end portion of the inner base portion 202, and the tip portion is closed by the force applied from the outside so that the hull portion 12 can be sandwiched. Specifically, the sandwiching portion 204 is formed by bending the two side plates 210 whose distances gradually increase from the inner base portion 202 toward the tip, and the edge of the tip of each side plate 210 being bent inward. And a sandwiching plate 212. Therefore, when a force is applied from the outside of each side plate 210, as shown in FIG. 5, the base portion of each side plate 210 (the boundary portion between the side plate 210 and the inner base portion 202) bends, and the leading end of the sandwiching plate 212 facing each other. The interval of becomes narrower.

As illustrated in FIG. 4, the outer metal fitting 40 includes an outer base portion 402, a contact portion 404, and a grounding portion 406. The outer base portion 402, the contact portion 404, and the grounding portion 406 are integrally formed by bending a single plate material.
The outer base portion 402 is provided above the inner base portion 202 and can support a frame F (see FIGS. 1 and 2B) provided around the solar cell module SP. A second hole H <b> 2 is formed in the central portion of the outer base portion 402. The second hole H2 is a square hole, for example.
The contact portions 404 are provided at both end portions of the outer base portion 402 and contact the outside of the sandwiching portion 204 of the inner metal fitting 20 to generate a force.
The grounding portion 406 is provided at the tip of the contact portion 404 so as to protrude outward, and contacts the roof plate 14.

2A and 2B, the fastening body 50 generates a force in a direction in which the inner base portion 202 of the inner metal fitting 20 and the outer base portion 402 of the outer metal fitting 40 approach each other. Can be tightened.
The fastening body 50 includes, for example, a square root bolt (an example of a bolt) 502 and a nut 504 corresponding to the square root bolt 502. The square root bolt 502 is inserted from the first hole H1 formed in the inner base portion 202 toward the second hole H2 formed in the outer base portion 402, and the square root portion is fitted into the first hole H1. Fit. As shown in FIGS. 2A and 2B, the nut 504 is fastened to the square root bolt 502 via a positioning fitting 70 described later.

The solar cell module mounting bracket 10 further includes a positioning bracket 70 and a pressing bracket 80.
As shown in FIG. 4, the positioning fitting 70 has a first positioning portion 702 formed by bending both ends of a single plate material upward. The first positioning portion 702 can position the frame F of the solar cell module SP in the direction along the surface of the roof plate 14 (direction along the light receiving surface of the solar cell module SP). In plan view, a third hole H3 through which the square root bolt 502 passes is formed at the center of the positioning fitting 70. As shown in FIGS. 2A and 2B, the positioning fitting 70 is mounted on the outer base portion 402 of the outer fitting 40 and is fixed to the outer base portion 402 by square root bolts 502 and nuts 504 passing through the third hole H3. ing.

As shown in FIG. 2B, the presser fitting 80 can press the upper surface of the frame F of the solar cell module SP from above. Specifically, as shown in FIG. 4, the presser fitting 80 is formed with a presser 802 that presses the frame F by bending both ends of a single plate. Further, a fourth hole H4 through which the square root bolt 502 passes is formed in the center portion of the presser fitting 80 in plan view.
As shown in FIG. 2B, the presser fitting 80 is fixed by a square root bolt 502 and a nut 506 that pass through the fourth hole H4.

Next, a method for mounting the solar cell module SP using the solar cell module mounting bracket 10 will be described.
The solar cell module SP is attached to the roof plate 14 by executing the following steps.

(Step S1)
At a predetermined position, the inner metal fitting 20 is covered with the hull portion 12. The square root bolt 502 is inserted in advance so that the square root portion fits into the first hole H1. Since the square root portion of the square root bolt 502 is fitted in the first hole (square hole) H1, the rotation of the square root bolt 502 is suppressed when tightening the nut 504 in step S3 described later, and the workability is improved. .

(Step S2)
The square root bolt 502 is passed through the second hole H2 of the outer metal fitting 40, and the outer metal fitting 40 is placed on the inner metal fitting 20.

(Step S3)
The nut 504 is fastened to the square root bolt 502 via the positioning fitting 70. As the nut 504 is tightened, the distance D (see FIG. 3) between the inner base portion 202 of the inner metal fitting 20 and the outer base portion 402 of the outer metal fitting 40 is reduced, and the root portions of the side plates 210 of the inner metal fitting 20 are bent. The lower end portion of the side plate 210 is pushed from the outside by the contact portion 404 of the outer metal fitting 40. As a result, the interval between the opposing clamping plates 212 of the clamping portion 204 of the inner metal fitting 20 is narrowed, and the root of the hull portion 12 is sandwiched.
The grounding portion 406 of the outer metal fitting 40 is in contact with the roof plate 14 as shown in FIG. 2A. Thus, since the grounding part 406 which contacts the surface of the roof board 14 is provided, the outer metal fitting 40 is fixed more stably.

(Step S4)
The solar cell module SP is attached. Specifically, the end face A (see FIG. 1) of the frame F of the solar cell module SP is abutted against the first positioning portion 702 of the positioning fitting 70 to position the frame F, and the upper surface of the outer base portion 402 of the outer fitting 40 is positioned. Put it on.

(Step S5)
The nut 506 is tightened to fix the presser fitting 80 from above the frame F.

  By executing the above steps S1 to S5, the solar cell module SP is attached to the roof plate 14 having the hull portion 12.

  Thus, the solar cell module mounting bracket 10 is excellent in workability because it is fixed to the hull portion 12 simply by inserting a tool from above and tightening one nut 504. Further, if the nut 504 is loosened, the inner metal fitting 20 and the outer metal fitting 40 can be shifted in the direction in which the hull portion 12 extends, so that it is easy to correct the mounting position of the solar cell module mounting bracket 10.

  The present invention is not limited to the above-described embodiment, and modifications can be made without changing the gist of the present invention. For example, a case where the invention is configured by combining some or all of the above-described embodiments and modifications is also included in the technical scope of the present invention.

  In the above-described embodiment, the square root bolt 502 is fastened with the nut 504, but the present invention is not limited to this. For example, instead of the square root bolt, a stud bolt extending in the vertical direction may be used in which the lower end portion is welded to the outer base portion of the outer metal fitting.

  Moreover, as shown in FIG. 6, it is also possible to form the 2nd positioning part 702a bent upwards in the edge part of the outer side base part 402a of the outer metal fitting 40a. By positioning the projecting portion B (see FIG. 1) of the frame F against the second positioning portion 702a and positioning the frame F of the solar cell module SP, it is possible to reduce the positioning metal fittings on which the first positioning portion is formed. . That is, instead of the positioning fitting, an outer fitting having a second positioning portion may be used.
