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

  FIG. 1 shows a fixing bracket for fixing a roof installation equipment 3 installed on a flat roof material 2 that is stacked in a multistage manner from the lower side B to the upper side A. It is a side view which shows an example of the attachment structure of 4.

  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. This type of flat roofing material 2 has been widely used in recent years because of its light weight and good handleability.

  In this example, the horizontal flat roof materials 2 closely arranged in the left-right direction are vertically stacked in multiple stages from the lower water side B to the upper water surface A, and the flat roof material 1/2 for each step. It is rolled up on asphalt roofing (not shown) in a state shifted by left and right.

  In addition, in order to give a feeling of subdivision of each flat roof material 2, slit portions 15 extending linearly in the gradient direction (eave ridge direction) of the roof 1 are respectively provided in the lower part of the underwater side B of each flat roof material 2. A plurality are formed at equal intervals in the left-right direction (direction perpendicular to the eaves-ridge direction).

  In FIG. 1, 16 indicates a field plate, 17 indicates a brick nail, A indicates a water side (ridge side) of the roof 1, and B indicates a water side (eave side) of the roof 1.

  Here, in this invention, the waterproof cover 5 for covering the flat roof material 2 to which the fixing metal fitting 4 of the solar cell panel 3A is fixed is provided. This waterproof cover 5 prevents rainwater from entering the screw holes n of the flat roof materials 2A and 2B, and the caulking agent 18 injected into the screw holes of the flat roof materials 2A and 2B is cut or the caulking agent. Even if 18 injections are forgotten, it works to prevent water leakage from that part. 2A is a plan view of the waterproof cover 5, FIG. 2B is a side view, and FIG. 2C is a flat roof material 2A having two upper and lower stages (or three or more upper and lower stages) adjacent to the gradient direction of the roof 1. It is a side view explaining the state which covers each surface exposure part 8 of 2B continuously. In this example, a step portion 5a is formed on the center side of the waterproof cover 5 so as to be bent along the surface exposed portions 8 of the two-level flat roof materials 2A and 2B. It can be laid in close contact with the surface exposed portions 8 of the two-step flat roof materials 2A and 2B.

The size of the waterproof cover 5 is longer than the fixing bracket 4 and wider than the fixing bracket 4. In this example, for example, as shown in FIG. 5B, a total of three surfaces are covered across _one flat roof material 2B on the lower stage side and two left and right flat roof materials 2A ₁ and 2A ₂ on the upper stage side. It has a size. Specifically, the width is about 450 mm and the total length is about 400 mm, but it is not limited to this value. The material of the waterproof cover 5 is not particularly limited, although a pressed product of sheet metal such as iron or stainless steel or a resin molded product such as polycarbonate may be used.

  The upper end portion of the waterproof cover 5 is an upper insertion piece 6. As shown in FIG. 2C, the upper insertion piece 6 includes an upper part on the upper side A of the uppermost flat roof material 2A covered with the waterproof cover 5 and an underwater side B of the upper level flat roof material 2C. It is inserted into the gap of the overlapping portion 9 with the lower part of. The insertion dimension m at this time is about 40 mm, for example. The upper insertion piece 6 serves to prevent rain water flowing from the water upper side A from flowing from the upper end portion of the waterproof cover 5 to the back surface, and further serves to fix the upper end portion of the waterproof cover 5 to the flat roof material 2C. .

  A lower locking piece 10 that protrudes downward is provided at the lower end of the waterproof cover 5. The lower locking piece 10 is hooked on the lower end surface of the lowermost flat roof material 2 </ b> B covered with the waterproof cover 5 so that the insertion dimension m between the overlapping portions 9 of the upper insertion piece 6 can be regulated. The bent shape of the lower locking piece 10 may be either an L shape as shown in FIG. 2 or a U-shaped folded shape as shown in FIG.

  As shown in FIG. 3A, a waterproof packing 11 is attached to the back surface of the waterproof cover 5 so as to surround the screw holes around the flat roof materials 2A and 2B. The waterproof packing 11 is made of a sealing material such as an eptosealer having a substantially trapezoidal shape with no bottom. The waterproof packing 11 prevents rainwater from reaching the screw holes n of the flat roof materials 2A and 2B even if rainwater enters the back surface of the waterproof cover 5.

  On the other hand, a fixing metal fitting 4 shown in FIG. The fixing bracket 4 is formed in an inverted U-shaped cross section arranged so as to straddle the upper and lower flat roof materials 2A and 2B covered with the waterproof cover 5, and the length of the fixing bracket 4 is on the upper surface thereof. A straight groove 14 is opened along the direction, and a connecting bolt 12 with a nut (FIG. 1) as a solar cell panel fitting is variably fitted in the groove 14 in the gradient direction of the roof 1. It has become.

  A pair of left and right flat plate-like fixing portions 7 are projected from the front end portion and the rear end portion of the fixing bracket 4, respectively. Each fixing portion 7 has a screw hole into which a screw 13 with packing (FIG. 1) is inserted. Here, the screw 13 with packing inserted into the left and right fixing portions 7A located on the water upper side A penetrates the upper part of the water upper side A of the waterproof cover 5 and is driven into the upper flat roof material 2A. The screw 13 with packing attached to the fixing portion 7B located on the underwater side B penetrates the lower side of the underwater side B of the waterproof cover 5 and is driven into the lower flat roof material 2B. Further, in this example, as shown in FIG. 1, the packing-side screw 13 on the water upper side A is driven into the base plate 16 through the overlapping portion 9 of the flat roof material 2A on the upper stage side and the flat roof material 2B on the lower stage side. On the other hand, the screw 13 with packing on the underwater side B penetrates the overlapping portion 9 between the flat roof material 2B on the lower stage side and the flat roof material 2 on the lower stage side, and is driven into the base plate 16. ing.

  Next, a procedure for sequentially installing the fixture 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 in FIG. 5 (a), first, the surface exposed portions of the upper and lower two-level flat roof materials 2A and 2B that are piled up at predetermined locations on the roof 1 as shown in FIG. 5 (b). The waterproof cover 5 is disposed so as to continuously cover 8. At this time, as shown in FIG. 2 (c), the upper insertion piece 6 provided at the upper end of the waterproof cover 5 is connected to the upper part of the upper side A of the uppermost flat roof material 2A covered with the waterproof cover 5 and the upper part thereof. It inserts in the clearance gap of the overlap part 9 with the lower part of the underwater side B of the flat roof material 2C of the side.

  Thereafter, as shown in FIG. 5C, the fixing bracket 4 is arranged on the surface side of the waterproof cover 5 so as to straddle the two upper and lower flat roof materials 2A and 2B. At this stage, fixing to the flat roof material 2 is not performed.

  Then, the electric drilling tool 20a shown in FIG. 5 (d) is used to drill the front holes in the waterproof cover 5 and the upper and lower two-level flat roof materials 2A and 2B, and the cutting powder is removed with a dust pump (not shown). Then, the caulking agent 18 is injected into the tip hole using the caulking agent supply device 19 shown in FIG.

  After that, among the fixing portions 7A and 7B provided at a plurality of locations of the fixing bracket 4, the screw 13 with packing (FIG. 1) attached to the fixing portion 7A located on the waterside A is shown in FIG. 5 (f). 20b penetrates the tip hole of the waterproof cover 5 and drives it into the tip hole of the upper flat roof material 2A. Similarly, the waterproof cover 5 is formed by driving the screw with packing 13 attached to the fixing portion 7B located on the waterside B through the front hole of the waterproof cover 5 and driving into the front hole of the flat roof material 2B on the lower stage side. Is finished (state shown in FIG. 6). Here, it is possible to prevent the waterproof cover 5 and the flat roof material 2 from being lifted or broken when the screws are driven by pre-drilling the waterproof cover 5 and the flat roof materials 2A and 2B. Stopping work becomes easy.

  Thereafter, as shown in FIG. 7, the connecting bolt 12 with a nut is slidably fitted into the groove 14 of the fixture 4.

  The above-described series of waterproof cover 5 and fixing bracket 4 are attached at four locations on the roof 1 (four locations P1 to P4 in FIG. 8A).

  Thereafter, as shown in FIG. 8 (b), a pair of upper and lower horizontal bars 21 are attached using the connecting bolts 12 with nuts provided on the respective fixing brackets 4. Finally, as shown in FIG. 8 (c), the horizontal bars 21 are attached. A solar cell panel 3A is attached to the panel. In place of the mounting method using the horizontal rail 21 in FIG. 8, the fixing bracket 4 is fixed to, for example, six locations P1 to P6 of the roof 1 without using the horizontal rail 21 as shown in FIG. It is also possible to directly attach the solar cell panel 3A to the connecting bolt 12 with a nut.

  Thus, the upper and lower two-level flat roof materials 2A and 2B to which the fixing bracket 4 of the solar battery panel 3A is fixed are covered with the waterproof cover 5, and the upper insertion piece 6 of the waterproof cover 5 is more than the upper end of the waterproof cover 5. By inserting into the overlapping portion 9 between the flat roof materials 2A and 2C located on the upper stage side, rain water flowing from the water upper side A cannot flow from the upper end of the waterproof cover 5 to the back surface of the waterproof cover 5, and the waterproof cover. 5 is drained to the lower side B through the surface of 5. Therefore, since it is possible to prevent rainwater from entering the screw holes around n of the flat roof materials 2A and 2B on the back surface side of the waterproof cover 5, there is a crack in the screw holes around n of the flat roof materials 2A and 2B. However, rainwater does not enter the crack, and leakage and corrosion from the crack to the back of the hut can be reliably prevented. Moreover, since the waterproof cover 5 is partially installed on the upper and lower two-level flat roof materials 2A and 2B to which the fixing bracket 4 is attached, not the entire roof 1, but the waterproof cover 5 can be reduced in size while improving the waterproof property. As a result, the waterproof cover 5 makes it possible to carry out raining around the screw holes n of the flat roof materials 2A and 2B at low cost and efficiently. Furthermore, since the fixing part 7A located on the water upper side A and the fixing part 7B located on the water lower side B provided on the fixing bracket 4 are respectively fixed to the upper and lower flat roof materials 2A and 2B, In the flat roofing materials 2A and 2B, the generation of cracks due to screwing can be prevented as much as possible, and damage to each flat roofing material 2 can be minimized.

  Moreover, since the waterproof packing 11 is attached to the back surface of the waterproof cover 5 so as to surround the screw holes n of the flat roof materials 2A and 2B, rainwater enters the back surface of the waterproof cover 5 from the water upper side A and the lateral direction. However, the rainwater is prevented from advancing around the screw holes n of the flat roof materials 2A and 2B by the waterproof packing 11, and is discharged downward. Moreover, when the slit part 15 for improving a feeling of splitting is perforated in the lower part of the underwater side B of the flat roof material 2 of each step as in this example, the upper and lower 2 covered with the waterproof cover 5 In the flat plate roofing materials 2A and 2B, rainwater may enter the overlapping portion 9 between the flat plate roofing material 2B on the lower stage side from the slit 15 of the flat roofing material 2A on the upper stage side (the broken line portion in FIG. Shows an example of the intrusion direction). However, in this example, since the waterproof packing 11 having a substantially trapezoidal shape without a bottom is attached to the back surface of the waterproof cover 5 so as to surround the screw holes n of the flat roof materials 2A and 2B, The rainwater that has entered is blocked by the waterproof packing 11 and can be prevented from reaching around the screw holes n of the flat roof materials 2A and 2B.

  Further, even when rainwater flows backward from the underwater side B by blowing up rainwater from the underwater side B, the presence of the lower locking piece 10 protruding downward from the lower end portion of the waterproof cover 5 causes the lower end portion of the waterproof cover 5 to As a result, it becomes possible to prevent rainwater from entering the back surface of the waterproof cover 5, and as a result, resistance to rainwater blowing from the underwater side B is improved, and the waterproof effect around the screw holes n of the flat roofing materials 2 A and 2 B is further improved. It will surely be obtained.

  Moreover, the insertion dimension m between the overlapping parts 9 of the upper insertion piece 6 is regulated by hooking the lower locking piece 10 of the waterproof cover 5 on the lower end surface of the lowermost flat roof material 2 </ b> B covered with the waterproof cover 5. be able to. Since the waterproof cover 5 can be easily positioned with respect to the flat roof materials 2A and 2B, the mounting accuracy of the waterproof cover 5 can be easily secured, and the lower locking piece 10 is bent from the lower end of the thin waterproof cover 5, so that the waterproof cover 5 is waterproof. The rigidity of the cover 5 is increased. Therefore, the fixing bracket 4 can be easily and firmly attached to the appropriate positions of the upper and lower two-level flat roof materials 2A and 2B via the waterproof cover 5, and the workability and waterproofness can be improved. .

  Furthermore, in this example, the fixing bracket 4 and the solar cell panel 3A are separated, and a plurality of fixing brackets 4 are screw-fixed to a plurality of locations P1 to P4. Since the battery panel 3A is attached, the installation work of the solar panel 3A is safer and more comfortable than the conventional case where the fixing bracket integrated with the large-sized solar battery panel is screwed to the flat roof material. This has the advantage that the workability is greatly improved. Further, since the fixing bracket 4 and the solar cell panel 3A can be separately manufactured at the factory, there is an advantage that the productivity at the factory is improved. .

  In addition, in the field, a connecting bolt 12 with a nut as a solar panel mounting tool is slidably fitted in the groove 14 of the fixing bracket 4 so as to be variable in the gradient direction of the roof 1. Even when the fixing position of the solar panel 3A is shifted in the gradient direction, the horizontal position of the solar panel 3A can be easily adjusted by adjusting the position of the connecting bolt 12 with a nut, and the fixing positions of the fixing portions 7A and 7B can be adjusted. Therefore, there is an advantage that the mounting operation of the solar cell panel 3A becomes easy and the mounting efficiency is further improved.

  The fixing metal fitting 4 according to the present invention is not limited to the solar battery panel 3A, and 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, for example. Also widely applicable.
