  With such a configuration, when the fixing bracket 4 of the solar cell panel 3A is screw-fixed to the flat roof material 2, the fixing bracket 4 and the solar cell panel 3A are configured separately, and a plurality of the fixing brackets 4 are provided. Since the solar panel 3A can be attached to these fixing brackets 4 after the screws are fixed to a plurality of locations on the roof 1, the solar panel integrated fixing brackets are screwed on the flat roof material as before. Compared to the case of fixing, the mounting operation of the solar cell panel 3A at a high place can be performed in a safe and reasonable posture. In addition, the rain cover around the screw hole of the flat roof material 2 to which the fixing bracket 4 is screwed can be easily performed using the waterproof cover 5 wider than the fixing bracket 4.

  Further, a horizontally long waterproof cover holding portion 6 erected upward from the underwater B portion of the substrate portion 13 is provided, and the underwater end portion 5A of the waterproof cover 5 is inserted into the waterproof cover holding portion 6. In this case, since the water-side end 5a of the waterproof cover 5 can be held simply by being inserted into the water-proof cover holding portion 6, the water-side end 5a of the water-proof cover 5 is flattened with a screw or the like. There is no need to fix it to the roofing material.

  The present invention can easily perform the work of mounting the solar cell panel on the flat roof material in a safe and reasonable posture, so that the effect of greatly improving the workability is obtained, and the fixing bracket is fixed with screws. It is possible to carry out the rain around the screw hole of the flat roof material at low cost and efficiently.

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

  FIG. 1 is an explanatory diagram of an example of a procedure for installing the solar cell panel 3A, and FIG. 2 shows a roof installation facility 3 on a flat roof material 2 that is stacked in multiple stages from the water side B to the water side A. It is side surface sectional drawing which shows an example at the time of fixing the fixing metal fitting 4 with screws. In FIG. 2, 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 spread over asphalt roofing (not shown) in a state shifted to the left and right by 21/2 sheets of 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. The horizontally-long slit-shaped waterproof cover holding part 6 and the horizontal piece 7 projecting from the upper part of the waterproof cover holding part 6 and connecting and fixing the solar cell panel 3A are integrally configured.

  The said board | substrate part 13 is formed in flat plate shape of planar view substantially rectangular shape, and as shown in FIG. 2, 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. 1 and FIG. 3G, the waterproof cover 5 is hatched for easy understanding of the drawings.

  Next, a procedure for installing the fixing bracket 4 and the solar cell panel 3A in order 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. 2) 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 waterproof cover 5 is covered. At this time, as shown in FIG. 1 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 flat roof materials 2B and 2C on the upper stage side. The insertion dimension at this time is about 40 mm, for example. On the other hand, the underwater side end 5a of the waterproof cover 5 is inserted into the waterproof cover holding part 6 having the horizontally long slit shape of the fixing bracket 4 to complete 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. 1A). Thereafter, as shown in FIG. 1B, the pair of upper and lower horizontal bars 24 are connected to the horizontal piece 7 provided on each fixing bracket 4 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, when the fixing bracket 4 of the solar cell panel 3A is screw-fixed to the flat roof material 2 having the above-described configuration, the fixing bracket 4 and the solar cell panel 3A are configured separately, and a plurality of fixing brackets 4 are provided. Since the solar panel 3A can be attached to these fixing brackets 4 after screws are fixed to a plurality of locations on the roof 1, the solar cell panel integrated fixing brackets are fixed to the flat roof material with screws as before. Compared with the case where it does, the attachment operation | work of the solar cell panel 3A in a high place can be performed with a safe and unreasonable attitude | position. In addition, when the solar cell panel 3A is connected and fixed to the horizontal piece 7 of the fixture 4, the horizontal piece 7 is provided on the upper part of the waterproof cover holding part 6, so that 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. As a result, the workability can be greatly improved and the productivity in the factory can be improved.

  Moreover, in this example, after fixing the board | substrate part 13 of the fixing metal fitting 4 to the flat roof material 2 (2A), while covering the board | substrate part 13 with the waterproof cover 5, the water-side edge part 5a of the waterproof cover 5 is fixed metal fittings. By holding by the waterproof cover holding part 6 provided in 4, for example, even if rainwater blows up from the underwater side B, the waterproof cover 5 can be prevented from rolling up using the fixing bracket 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. Can prevent water leakage. Moreover, 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 roofing material 2, and the water-side end portion 5 </ b> B of the waterproof cover 5 is on the upper side. By inserting into the overlapping portion 9 of the flat roofing materials 2B and 2C, rainwater flowing down from the water upper side A does not flow down the upper surface of the waterproof cover 5 as shown by W1 in FIG. . In this example, the outer periphery of the screw 11 is watertight with the waterproof packing 50 (FIG. 4). As shown by W in FIG. 4, it is possible to prevent rainwater flowing on the upper surface of the base plate 10 from flowing down from the screw hole of the screw 11. As a result, there is also an advantage that the raining around the screw hole of the flat roof material 2 (2A) to which the fixing metal fitting 4 is fixed by screws can be performed inexpensively and efficiently.

  Further, since the water-side end portion 5a of the waterproof cover 5 can be held simply by being inserted into the horizontally long slit-shaped waterproof cover holding portion 6, it is not necessary to fix the water-side end portion 5a of the waterproof cover 5 with screws or the like. .

  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.

  Although the solar cell panel 3A has been exemplified in the above-described embodiment, it can be widely applied to a mounting structure for functional parts such as a solar heat collecting panel that collects solar heat similar to this and uses it as hot water, or a planting planted green panel. is there.
