Description

  TECHNICAL FIELD The present invention relates to a fixing structure for a solar-powered device that collects heat and / or generates power, such as a solar battery panel or a solar water heater installed on the roof of a building such as a house.

  Conventionally, in a solar-powered device that installs a structure consisting of a solar cell panel, a solar water heater, etc. on the roof of a house, the base ends of wires such as stainless steel wires are connected to the four corners of the structure, and the periphery of the roof The structure was fixed to the roof by fixing the structure with nails and screws.

  Generally, if a solar-powered device is supported only by a roof tile, the solar-powered device may move up and down due to strong wind blowing on the solar-powered device, and the roof tile may break or fall off. In order to securely fix the roof so that it does not move, it is preferable to support it by a roof structure such as a base plate under the roof tile.

  Therefore, as shown in FIG. 13, as a method of directly supporting the solar light utilizing device S on the roof structure, one end of a support member 29 that is a thin metal such as a stainless steel plate is overlapped with the adjacent tile 4a and tile 4b. A method of fixing the support member such as the solar power utilization device S or a rail supporting the device to the other end of the support member 2 that is led to the base plate 51 under the roof tile and fixed to the other end of the support member 2 on the surface of the roof tile. Is used.

  As another supporting method, as shown in FIG. 12, instead of the roof tile, a shape similar to the roof tile is formed of aluminum alloy or the like, and the solar light utilizing device S or the same device is supported on the upper portion. There is a method in which a supporting tile 5 provided with a supporting portion for fixing a supporting member such as a rail is installed on the field board 51 in a mixed manner with other tile materials 4.

  Although not shown in particular, there is a method in which a through-hole is processed in the roof tile at the time of construction of the solar-powered device, and the solar-powered device is supported by the metal fitting through the processed through-hole.

  However, when the thin metal fitting shown in FIG. 13 is passed through the overlapping portion of the roof tile and the roof tile and fixed to the field board or the like, a gap is generated in the overlapping portion of the roof tile even if the metal fitting is thin. There is a problem of intrusion.

  In addition, the method of using a support tile made of aluminum alloy or the like having a shape similar to that of the roof tile shown in FIG. 12 uses an aluminum alloy casting, so that the strength of the support roof is difficult to break. Since the adjacent tiles are installed so as to overlap each other, it is difficult to insert the tiles, and the support tiles cannot be broken and removed at the time of removal, which requires a lot of time for removal.

  Furthermore, in the method of processing a through hole for passing a metal fitting through the roof tile during the roof tile construction, the through hole is processed in the field to a roof that is easy to break, which requires careful work and labor. There is a problem that rainwater may intrude through the open through-holes.

In order to solve such a problem, as shown in FIG. 14, as shown in FIG. 14, a metal-formed roof tile 1 having the same appearance as a roof tile and having a through hole is arranged between the roof tiles 4 (4 a, 4 b), and 1, covering the supporting member 2 fixed to the roof base material 5, and further, as shown in FIG. 15, a fixing structure in which the solar light utilizing device S is installed on the roof via the vertical rack 61 or the like on the supporting member 2. It has been proposed (see, for example, Patent Document 1).
JP 2004-3132 A

  However, as described above, the metal molding tile 1 having the same appearance as the roof tile and provided with a through hole covers the support member attached to the roof base material 51 and fixes the solar power utilization device to the roof base material. In the structure, by covering the support member 2 with the metal molding tile 1, it is possible to fix the solar power utilization device S while preventing the intrusion of rainwater. However, as shown in FIG. Since it is necessary to let the underlap 13 of the metal-molded roof tile 1 enter under the adjacent roof tile 4a on the left side above the 4b underwrap 41, the upper roof tile 4b is lifted and further slipped between the left and right roof tiles. The workability was poor because it was necessary to perform complicated work such as mounting. In particular, as shown in FIG. 15, this method has a structure in which the upper end of the metal-molded roof tile 1 is hooked on the roof rail 52 in order to align the flow direction of the metal-molded roof tile 1, so that a metal is placed under the upper roof tile 4b. The roof tile 4a must be lifted in order to carry the molded roof tile 1 over, so that the workability is poor.

  Therefore, the present invention has been devised in view of the above-mentioned problems, and particularly a large and heavy structure such as a solar battery panel or a solar water heater is installed on the roof of a building. It is an object of the present invention to provide a solar cell panel support structure that is excellent in workability while preventing rainwater from entering in a fixing structure for a solar light utilization device suitable for the above.

  Moreover, in the fixing structure of the solar light utilization device of the present invention, the roof tiles are arranged in a matrix on the roof, and the covering portion of the metal tile is an end portion of the roof tile adjacent in the row direction. Is covered and pressed.

  Furthermore, the fixing structure of the solar light utilization device of the present invention is the above-described fixing structure, wherein the metal tile covers one end of the roof tile adjacent to the row direction in the row direction and the row. The other end in the direction is open below the end of the other roof tile of the roof tile adjacent in the row direction.

  Still further, in the fixing structure of the solar light utilization device according to the present invention, in the fixing structure, the other end of the metal tile in the row direction is pressed downward by an end portion of the other roof tile adjacent to the row direction. It is characterized by.

  The fixing structure of the solar light utilization apparatus of this invention coat | covers the edge part of the roof tile adjacent to a row direction with the coating | coated part of a metal tile, and supports at least one of this adjacent roof tile from the downward direction. Therefore, it becomes difficult for rainwater to enter between the metal tile and the roof tile, and the water stoppage is improved.

In addition, since the other end of the metal tile is opened below the end of the roof tile adjacent in the row direction, the troublesome work such as hooking the other end on the roof tile rail of the roof is conventionally performed. It becomes unnecessary and construction becomes easy.

Thereafter, the support member 2 is fixed on the roof base material 5. Next, the eaves member 3 is attached so as to sink into the lower half of the adjacent roof tile 4a (so that the end of the roof tile 4a is in the range of the eaves of the interrogation member 3). FIG. 6 shows a state in which the eaves member 3 has been attached on the roof base material 5 with screws in such a manner. Moreover, in order to explain the attachment state of the eaves member 3, the figure which removed the roof tile 4a of the eaves member 3 upper part is shown in FIG. The eaves member 3 is attached between the metal molding tile 1 and the tile 4a.

  Finally, as shown in FIG. 7, the metal molding tile 1 is attached so that the support bolt 21 of the support member 2 penetrates through the through hole 14 of the metal molding tile 1. At this time, although not particularly illustrated, the metal-molded roof tile 1 is attached so as to be placed on the adjacent roof tiles 4a and 4b, and the upper roof tile is lifted and inserted into the lower portion thereof.

  FIG. 9 shows a cross-sectional view in the girder direction at this time.

The metal-molded roof tile 1 is placed from above, and is tightened by the nut 22 through the packing 23 at the convex portion 16 of the metal-molded roof tile 1. By preventing the intrusion of rainwater from the through-hole 14 of the metal-molded tile 1 and pressing it on the adjacent tiles 4a and 4b, it is possible to prevent a gap from being formed between the adjacent tiles. For example, even when rainwater enters between the tile cover portion 11 and the adjacent tile 4 a toward the roof base material 5, the rainwater travels along the eaves member 3 and is discharged onto the eaves side tile. In addition, the rain return 31 of the gutter member 3 is preferably in contact with the lower part of the adjacent roof tile 4 in order to prevent rainwater from entering between the adjacent roof tiles, and a metal such as an elastically deformed steel plate may be used. By adopting such a waterproof structure, there is no need to provide a member such as an underlap portion on the metal molding tile 1, and the metal molding tile 1 has a simple structure, and the underlap portion is allowed to enter under the adjacent roof tile. Since it is not necessary, the workability is also improved.

  Further, as shown in FIG. 11, the right end 12 is structured to be placed on the underlap 41 of the right tile 4b and the tile cover portion 11 is placed on the left tile 4a.

Since there may be, you may make it eliminate the bending part of the metal molding tile 1. FIG. By doing in this way, construction becomes easy and the processing man-hour of a metal forming tile is reduced.

  FIG. 11 shows a state in which the solar light utilizing device S is arranged on the fixing structure of the solar light utilizing device installed on the tile roof as described above. Of the many tiles arranged on the roof, the vertical rack 61 is fastened and fixed to the support bolt 21 having a fixed structure including the support member 2 and the metal-formed tile 1 installed between the tiles 4a and 4b. A plurality of horizontal racks 62 are fixed on the vertical rack 61, and the solar light utilizing device S is fixed to the horizontal rack 62.

  FIG. 10 shows another embodiment. A packing 33 is used instead of the rain return 31 of the eaves member 3. The packing 33 is made of a soft and elastic material such as sponge, and is thicker than the gap between the adjacent roof tile 4a and the eaves member 3. By doing so, the packing 33 is compressed by the dead weight of the roof tile 4a, and it is possible to prevent rainwater from entering the roof base material 5 by filling the gap between the roof tile 4a and the roof member 3. Further, since the right end portion 12 is constructed on the right tile 4b and the tile cover portion 11 is constructed on the left tile 4a, the difference in thickness depending on the type of various tiles, Without worrying about the difference in depth, installation without misalignment can be performed without specially designing the shape of the metal molding tile 1 for each type.
