  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 is a side cross-sectional view illustrating an example of a case in which a fixing bracket 4 of a roof installation equipment 3 is screw-fixed on a flat roof material 2 that is rolled up and down in multiple stages from a water side B to a water side A. . In the figure, 10 indicates a field plate, A indicates the water side (ridge side) of the roof 1, and B indicates the water side (eave side) of the roof 1.

  In the following example, the solar panel 3 </ b> A that generates power with sunlight is illustrated as the roof installation facility 3.

  The flat roof material 2 is exemplified by a slate tile, for example, but may be a cement tile, a clay tile, a resin tile, or the like. In recent years, this type of flat roof material has been widely used because of its light weight and good handleability.

  In this example, the row of flat roofing materials 2 closely arranged in the left-right direction are stacked in multiple stages from the lower water side B to the upper water surface A, and as shown in FIG. Are stacked on asphalt roofing (not shown) in a state shifted to the left and right by half of the flat roofing material.

Here, in the present invention, the fixing bracket 4 of the solar cell panel 3A includes the base plate portion 13 fixed with screws 11 to the surface exposed portion 8 of the flat roof material 2, and the underwater B portion of the base plate portion 13. a waterproof cover holding part 6 standing upright, a horizontal plate 7 for connecting and fixing the solar cell panel 3A so as to project from the upper portion of the waterproof cover holding portion 6 are integrally formed, the waterproof cover holding section 6 It has a horizontally long slit.

  The said board | substrate part 13 is formed in flat plate shape of planar view substantially square shape, and as shown in FIG. 1, the length of the eaves-ridge direction is the surface exposure part 8 of the one flat roof material 2 (2A). The length from the water upper side A to the water lower side B is substantially equal to the length. Screw holes 12a are opened at a plurality of locations (four locations in this example) of the base plate portion 13, and the screws 11 are overlapped portions 9 (two layers) of the two-level flat roof material 2 from the screw holes 12a of the base plate portion 13. And the like) and is driven into the field board 10.

  The upper surface of the substrate portion 13 is covered with a flat waterproof cover 5 that is wider than the fixing bracket 4. The waterproof cover 5 prevents rainwater from entering through the screw holes 12a and 12b, and is formed of, for example, a pressed product of sheet metal such as iron or stainless steel or a resin molded product such as polycarbonate. In FIG. 3G and FIG. 4, the waterproof cover 5 is hatched for easy understanding of the drawings.

  Next, a procedure for sequentially installing the fixing bracket 4 and the solar cell panel 3A on the flat roof material 2 will be described with reference to FIGS.

In the existing roof 1 shown to Fig.3 (a), it fixes to the underwater side B of the surface exposed part 8 (equivalent to the surface exposed part 8 of the flat roof material 2A of FIG. 1) of one flat roof material 2 first. The board part 13 of the metal fitting 4 is placed, and a front hole is made from the screw hole 12a of the board part 13 to the flat roof material 2 with the electric drilling tool 20 shown in FIG. 3C, and the dust pump 21 shown in FIG. After the cutting powder is removed, the caulking agent 18 is injected into the tip hole using the caulking agent supply device 22 shown in FIG. Thereafter, the screw 11 with packing is driven through the screw hole 12a of the base plate 13 into the front hole of the flat roof material 2 by the electric screwdriver 23 of FIG. Thereby, the fixing operation of the fixing bracket 4 is completed. Thereafter, the substrate portion 13 is covered with the waterproof cover 5. At this time, as shown in FIG. 2 and FIG. 3G, the water-side end portion 5B of the waterproof cover 5 is inserted into the gap between the overlapping portions 9 of the upper flat roof materials 2B and 2C. The insertion dimension at this time is about 40 mm, for example. On the other hand, the underwater side end portion 5 a of the waterproof cover 5 is inserted into the horizontally long slit of the waterproof cover holding portion 6 of the fixing bracket 4 , thereby completing the attachment of the waterproof cover 5.

  A series of mounting operations of the fixing bracket 4 and the waterproof cover 5 are respectively performed at four locations on the roof 1 (for example, FIG. 4A). After that, as shown in FIG. 4B, the pair of upper and lower horizontal bars 24 are connected to the horizontal piece 7 provided on each fixing bracket 4 by using, for example, bolts and nuts, and finally, FIG. As described above, the solar cell panel 3 </ b> A is attached to the horizontal rail 24. It is also possible to omit the crosspiece 24 and attach the solar cell panel 3A directly to the horizontal piece 7 of the fixture 4.

  Thus, after fixing the base plate portion 13 of the fixing bracket 4 having the above structure to the flat roofing material 2 (2A), the base plate portion 13 is covered with the waterproof cover 5 and the underwater side end portion 5a of the waterproof cover 5 is fixed. By holding the waterproof cover holding portion 6 provided on the metal fitting 4, for example, even if rainwater blows up from the underwater side B, it is possible to prevent the waterproof cover 5 from rising using the fixing metal fitting 4. Accordingly, even if the screw holes 12a and 12b are broken or forgotten, or if cracks occur around the screw holes 12b of the flat roof material 2, the screw holes 12a and 12b, cracks, etc. Water leakage from water can be waterproofed. Further, the waterproof cover 5 of this example has a length and a width that can be covered over the surface exposed portion 8 of the upper and lower two-level flat roof material 2, and the water-side end portion 5 </ b> B of the waterproof cover 5 is on the upper side. 2 is inserted into the overlapping portion 9 of the flat roofing materials 2B and 2C, so that the rain water flowing down from the water upper side A flows down the upper surface of the waterproof cover 5 as shown by W1 in FIG. . Further, in this example, the outer periphery of the screw 11 is watertight with the waterproof packing 50 (FIG. 2), so that rain water flowing on the upper surface of the base plate 10 flows down from the screw hole of the screw 11 as indicated by W in FIG. Can be prevented. As a result, it is possible to carry out raining around the screw hole of the flat roof material 2 (2A) to which the fixing bracket 4 is fixed with screws at low cost and efficiently.

Further, since the water-side end 5a of the waterproof cover 5 can be held simply by being inserted into the horizontally long slit of the water-proof cover holding portion 6 , the water-side end 5a of the water-proof cover 5 is attached to the flat roof material 2 with screws or the like. There is no need to fix.

  Furthermore, when the solar cell panel 3A is connected and fixed to the horizontal piece 7 of the fixing bracket 4, since the horizontal piece 7 is provided on the upper part of the waterproof cover holding part 6, the solar cell panel 3A is connected to the waterproof cover holding part 6. There is no interference, and the installation of the solar cell panel 3A is accelerated. In addition, in this example, the fixing bracket 4 and the solar cell panel 3 </ b> A are separated, and a plurality of fixing brackets 4 are screw-fixed to a plurality of locations on the roof 1, and then the solar cell panel 3 </ b> A is attached to these fixing brackets 4. Since it is attached, the solar cell panel 3A can be attached in a safe and reasonable posture as compared with the case where a fixing bracket integrated with a large-sized solar cell panel is screwed to a flat roof material as before. Thus, not only the workability is greatly improved, but also the fixing bracket 4 and the solar cell panel 3A can be separately manufactured at the factory, which has the advantage of improving the productivity at the factory.

  Furthermore, the waterproof cover 5 is not installed on the entire roof 1, but is installed so as to straddle the board portion 13 of the fixing bracket 4 and the surface exposed portion 8 of the flat roof material 2 in the vicinity thereof. There are also advantages that can be made.

  The fixing metal fitting 4 according to the present invention is not limited to the solar battery panel 3A, and is used to fix various functional panels such as a solar heat collecting panel and a greening panel, or various roof installation equipment 3 such as a TV antenna installation stand. Widely applicable as a metal fitting.
