  Next, the construction procedure by the mounting structure of the solar panel 1 of the embodiment will be described.

  As shown in FIG. 2, a mounting bracket 4 is attached in advance to a bolt 3 fixed to the top of a tight frame that protrudes outward from the top 2 b of the stacked folding plate roof 2 via a dome nut 8. First, the first mounting bracket 10 is fastened and fixed via bolts 15 and nuts 16 from above the pair of mounting pieces 6 and 6 of the existing mounting bracket 4. At this time, the shank portion 15b of the bolt 15 is screwed into the mounting hole 6c of each mounting piece portion 6 of the existing mounting bracket 4, and the shank portion 15b projects in advance upward from the horizontal portion 6b of each mounting piece portion 6. By doing so, the first mounting bracket 10 can be easily and quickly assembled from above the existing mounting bracket 4.

  Next, in the shank portion 17b of the bolt 17 projecting upward from the surface 12a of the ceiling piece portion 12 of the first mounting bracket 10, the mounting hole of the lower horizontal portion 23 of the horizontal piece portion 22 of the second mounting bracket 20 is provided. As shown in FIG. 3, the lower end 21 b of the upright piece 21 of the second mounting bracket 20 is placed on the surface 12 a of the ceiling piece 12 of the first mounting bracket 10. Then, the end 1a of the solar panel 1 is inserted between the surface 12a of the ceiling piece 12 of the first mounting bracket 10 and the back surface 24b of the upper horizontal section 24 of the horizontal piece 22 of the second mounting bracket 20. Then, the nut 18 is fastened and fixed to the shank portion 17b of the bolt 17 protruding outward from the surface of the lower horizontal portion 23 of the horizontal piece portion 22 of the second mounting bracket 20, so that the ceiling of the first mounting bracket 10 is fixed. The end portion 1a of the solar panel 1 is fixed between the surface 12a of the piece portion 12 and the back surface 24b of the horizontal portion 24 at the upper stage of the horizontal piece portion 22 of the second mounting bracket 20.

If the thickness is slightly narrower than the thickness of the first mounting bracket 10, the solar mounting between the surface 12 a of the ceiling piece 12 of the first mounting bracket 10 and the back surface 24 b of the horizontal portion 24 of the upper horizontal piece 22 of the second mounting bracket 20 is performed. The edge part 1a of the panel 1 can be fixed reliably. Further, the shank portion 17b of the bolt 17 is screwed into the mounting hole 12b of the ceiling piece portion 12 of the first mounting bracket 10 so that the shank portion 17b protrudes upward from the surface 12a of the ceiling piece portion 12 in advance. The second mounting bracket 20 can be easily and quickly assembled from above the first mounting bracket 10.

  In this manner, as shown in FIGS. 6 to 8, by attaching the four locations of one solar panel 1 to the existing mounting bracket 4 via the mounting brackets 10 and 20, the existing stacked folding plate The solar panel 1 can be installed smoothly and efficiently on the top 2b of the roof 2 in a short time.

  In addition, since a plurality of mounting brackets 4 fastened and fixed in advance to the top 2b of the folded plate roof 2 are used, a number of fastening members such as a C-shaped steel frame for fixing the solar panel 1 as in the prior art becomes unnecessary. Therefore, the cost and weight can be reduced accordingly.

  In this way, the bolts 15 and the nuts 16 are fastened and fixed to the existing mounting bracket 4 that is previously attached to the top part 2b of the existing stacked folding plate roof 2, and the shank part 17b of the bolt 17 faces upward on the surface 12a. And the first mounting bracket 10 and the shank portion 17b protruding from the surface 12a of the ceiling piece 12 of the first mounting bracket 10 are fastened and fixed via nuts 18 to the first mounting bracket 10. A second mounting bracket 20 that sandwiches the end portion 1a of the solar panel 1 therebetween, and a shank portion 17b that protrudes from the surface 12a of the ceiling piece portion 12 of the first mounting bracket 10 via a nut 18 When the second mounting bracket 20 is fastened and fixed, between the surface 12a of the ceiling piece 12 of the first mounting bracket 10 and the back surface 24b of the horizontal portion 24 at the upper stage of the horizontal piece 22 of the second mounting bracket 20. In solar Since the end 1a of the panel 1 is sandwiched and fixed, the first mounting bracket 10 and the second mounting are sequentially installed from the top of the existing mounting bracket 4 attached to the top 2b of the existing folded plate roof 2. The metal fitting 20 can be assembled easily and reliably. Thereby, the solar panel 1 can be installed in the top part 2b of the existing folded-plate roof 2 in a short time smoothly and efficiently.

  The first mounting bracket 10 is an L-shaped pair of mounting pieces that are placed on the pair of mounting pieces 6 and 6 of the existing mounting bracket 4 and fastened and fixed via bolts 15 and nuts 16. 11 and 11 and a ceiling piece portion 12 which is integrally formed by bending to each upper end 11a of the pair of placement piece portions 11 and 11 and has a shank portion 17b of a bolt 17 protruding upward on the surface 12a. The second mounting bracket 20 has a lower end 21b bent and integrally formed on the standing piece 21 placed on the ceiling piece 12 of the first mounting bracket 10 and the upper end 21a of the standing piece 21. And a horizontal piece 22 formed with a holding hole 24a for penetrating the shank portion 17b and a holding portion 24 for holding the end 1a of the solar panel 1, and the surface of the ceiling piece 12 of the first mounting bracket 10 Bolt 1 protruding to 12a When the mounting hole 23a of the horizontal piece portion 22 of the second mounting bracket 20 is inserted into the shank portion 17b and the horizontal piece portion 22 is fastened and fixed via the nut 18, the ceiling piece of the first mounting bracket 10 is fixed. Since the end portion 1a of the solar panel 1 is sandwiched and fixed between the surface 12a of the portion 12 and the back surface 24b of the holding portion 24 of the horizontal piece portion 22 of the second mounting bracket 20, an existing mounting bracket The solar panel 1 can be easily and reliably reduced in the top 2b of the folded roof 2 with the minimum number of mounting brackets 10 and 20 having a small number of parts, ie, the first mounting bracket 10 and the second mounting bracket 20 attached to 4 It can be attached with.

  Further, the horizontal piece portion 22 of the second mounting bracket 20 has two upper and lower horizontal portions 24, 23. The lower horizontal portion 23 is provided with a mounting hole 23 a, and the upper horizontal portion as a holding portion. Since the end portion 1a of the solar panel 1 is held by the back surface 24b of 24, the end portion 1a of the solar panel 1 is formed by the two upper and lower horizontal portions 24, 23 and the pair of reinforcing portions 25, 25. The strength of the horizontal piece portion 22 of the second mounting bracket 20 to be held can be further improved, and the solar panel 1 can be firmly attached to the top portion 2 b of the folded plate roof 2.

  Further, as shown in FIG. 3, the first mounting bracket 10 placed on the pair of mounting pieces 6 and 6 of the existing mounting bracket 4 and fastened and fixed via bolts 15 and nuts 16; and The second mounting bracket 20 fastened and fixed to the shank portion 17b of the bolt 17 projecting from the surface 12a of the ceiling piece 12 of the first mounting bracket 10 via the nut 18 is a head portion 15a of each bolt 15 and 17. 17a are located on the lower side, and the shank portions 15b and 17b are located on the upper side, so that the nuts 16 and 18 are loosened or removed over time, so that the bolts 15 and 17 Even if it falls off, the situation can be easily confirmed from the outside, so that maintenance and inspection can be performed easily and reliably.

  Note that the existing mounting bracket 4 of the above-described embodiment is the one applied for by the present applicant in Japanese Patent Application No. 2012-237553, but other mounting brackets such as the mounting bracket filed by the present applicant in Japanese Patent Application No. 2013-005871 are also used.
