Description

  The present invention relates to a solar cell module mounting structure for mounting a solar cell module on a roof surface of a building.

  As one of the means for using clean energy, residential solar power generation systems that install solar cell modules on a roof surface of a building or the like and convert solar light energy into electric energy have become widespread.

  A solar cell module installed on a roof surface of a building or the like includes a module main body for converting light energy into electric energy, a module frame for holding the module main body, and the like. The module main body is formed, for example, as a super straight structure, and single crystal or polycrystalline solar cells are formed in a sandwich shape through a resin between glass and a weather resistant film. The module frame is formed of front and rear front and rear frames, left and right left and right frames. The module main body is held by surrounding the peripheral edge of the module main body with such a module frame.

  Conventionally, there are the following solar cell module mounting structures for mounting such a solar cell module on a roof surface of a building.

  For example, there is known a solar cell module mounting structure in which the number of anchor bolts for mounting the solar cell module on a roof surface of a building is reduced. Specifically, a rail fixing bracket is prepared for the anchor bolt, and a rail-like component (for example, a vertical beam) is attached to the rail fixing bracket. Furthermore, what attaches a solar cell module attachment component with respect to a rail-shaped component, and attaches a solar cell module with respect to this solar cell module attachment component is known. In this solar cell module mounting structure, rail fixing brackets, rail-like parts such as vertical bars, and solar cell mounting brackets are required.

  A solar cell module mounting structure in which the number of the above-described solar cell mounting brackets is reduced is known. Specifically, solar cell mounting brackets are prepared at certain intervals with respect to rail-like parts (for example, vertical rails). In addition, a solar cell module mounting component (for example, a horizontal rail) for mounting the solar cell module is separately prepared and attached to the solar cell mounting bracket. In this solar cell module mounting structure, rail-shaped parts such as rail fixing brackets and vertical rails, solar cell module mounting components such as solar cell mounting brackets and horizontal rails are required.

In addition, the installation of the solar cell module that attaches the solar cell module without making a hole in the folding roof by using a tight frame as the installation structure of the solar cell module that is easy to install and has good compatibility with the building plan A structure has been proposed (see, for example, Patent Document 1). Specifically, the longitudinal direction is set in a direction substantially orthogonal to the flow direction of the folded half-roof member, straddling from above the folded half-roof member, between at least a pair of tight frames fixed on the wife side frame on the lower side of the folded half-roof member. A solar cell module body is folded in half by installing a girder frame frame member that extends and attaching the solar cell module body to a wife frame frame that extends in the longitudinal direction in a direction substantially orthogonal to the girder frame member. The attachment structure of the solar cell module attached to the member is shown. In addition, as a solar cell module mounting structure for fixing a solar cell module without opening a fixing hole in a folded roof, a solar cell for mounting the solar cell module using a module fixing bracket and a roof fixing bracket via a support frame A module mounting structure has been proposed (see, for example, Patent Document 2).

  However, the conventional solar cell module mounting structure has the following problems.

  In the case of the solar cell module mounting structure using the rail-shaped parts such as the vertical rails and the solar cell module mounting parts such as the horizontal rails, if the size and arrangement of the solar cell modules installed on the roof surface are different, There is a problem that the solar cell module cannot be attached to the roof surface. In other words, rail-like parts such as vertical rails and solar cell module mounting parts such as horizontal rails are not common parts specifications that can accommodate various sizes and arrangements of solar cell modules. It is necessary to prepare new parts separately according to the arrangement and the like. Moreover, there is no unity in construction, and it is necessary to arrange components and attach components for each arrangement of solar cell modules.

  Both in the case of the solar cell module mounting structure in which the number of anchor bolts described above is reduced and in the case of the solar cell module mounting structure in which the number of solar cell mounting brackets described above is reduced, to the roof surface. There is a problem that the number of parts used for mounting the solar cell module increases, and the construction becomes complicated accordingly. Further, when replacing a damaged solar cell module, there is a problem that it is difficult to remove only the damaged solar cell module.

  The present invention has been made in view of the above-described problems of the prior art, can cope with various sizes and arrangements of solar cell modules, and has the number of components used for mounting the solar cell modules on the roof surface.

The inclined portion is connected to the base portion via the connecting portion, and is formed to be inclined by a predetermined angle with respect to the base portion.

  Further, in the solar cell module mounting structure of the present invention, long holes in the front-rear direction are formed in the upper surface of the roof-side fixing bracket, the base of the front mounting bracket, and the base of the rear mounting bracket, respectively. The roof-side fixing bracket and the front-side mounting bracket and the roof-side fixing bracket and the rear-side mounting bracket are mounted using these long holes.

  According to such a solar cell module mounting structure, since the mounting is performed using the long holes formed in each metal fitting, a certain degree of freedom can be given to the workability, and temporarily fixed on the roof side. Even if the fitting is not dimensioned as planned, or the attachment position of the roof-side fixing fitting to the roof surface is slightly shifted in the front-rear direction, attachment can be performed.

By preparing the number, it is possible to cope with various sizes and arrangements of solar cell modules. As a result, it is not necessary to prepare new parts for various arrangements of solar cell modules, etc., and mounting parts (roof-side fixing bracket, front-side mounting bracket, rear-side mounting bracket) can be shared. By reducing the number of parts, the cost can be reduced. And, by making the mounting parts common, the construction can be simplified, and the solar cell module can be mounted on the roof surface in a unified operation.

As shown in FIG. 8, the front mounting bracket 30 includes a base portion 31 in contact with each mounting bracket mounting surface 22 (upper surface) of the roof side fixing bracket 20, and an inclined portion 32 in contact with the front portion of the solar cell module 10. It has. The inclined portion 32 is formed to be inclined with respect to the base portion 31 by an angle α.

  In addition, two long holes 33 are formed in the base 31, and these long holes 33 are formed long in the front-rear direction. The distance between the two long holes 33 in the left-right direction is substantially the same as the distance between the long holes 24 formed in each mounting bracket mounting surface 22 of the roof-side fixing bracket 20 described above. FIG. 8 shows a state in which the bolt 35 is attached to the inclined portion 32. The bolt 35 is used when the front frame 13 of the solar cell module 10 is attached to the front mounting bracket 30 as described later.

  Next, the rear mounting bracket 40 will be described.

  The rear mounting bracket 40 is a bracket that is attached to the rear portion of the solar cell module 10 (FIG. 1). As shown in FIG. 9, the rear mounting bracket 40 includes a base portion 41 that contacts each mounting bracket mounting surface 22 (upper surface) of the roof-side fixing bracket 20 and an inclined portion that contacts a rear portion of the solar cell module 10. 42, and a connection portion 43 that connects the base portion 41 and the inclined portion 42. The inclined portion 42 is formed to be inclined with respect to the base portion 41 by an angle β. The inclination angle β of the inclined portion 42 is equal to the inclination angle α of the inclined portion 32 of the front mounting bracket 30 described above. The connection portion 43 is provided substantially perpendicular to the base portion 41 and is formed at a height h2. By changing the height h2 of the connection part 43, the inclination angle of the solar cell module 10 installed on the flat roof surface can be changed as appropriate.

  In addition, two long holes 44 are formed in the base 41, and these long holes 44 are formed long in the front-rear direction. The distance between the two long holes 44 in the left-right direction is substantially the same as the distance between the long holes 24 formed in each mounting bracket mounting surface 22 of the roof-side fixing bracket 20 described above. FIG. 9 shows a state in which the bolt 45 is attached to the inclined portion 42. As will be described later, the bolt 45 is used when the rear frame 14 of the solar cell module 10 is attached to the rear mounting bracket 40.

  The solar cell module 10 is attached to the flat roof surface using the roof-side fixing bracket 20, the front-side mounting bracket 30, and the rear-side mounting bracket 40 configured as described above. Then, the attachment to the flat roof surface of the solar cell module 10 is demonstrated. In addition, below, the case where the two solar cell modules 10a and 10b are installed adjacent to each other in the front-rear direction will be described with reference to FIGS. In FIG. 10, the front solar cell module is represented as 10a, and the rear solar cell module is represented as 10b.

  First, the roof-side mounting bracket 20 for mounting the front-side mounting bracket 30 and the rear-side mounting bracket 40 for the front-side solar cell module 10 a is fixed to the anchor bolt 50. Further, the roof side fixing bracket 20 for mounting the rear mounting bracket 40 for the rear solar cell module 10b is fixed to the anchor bolt 50. At this time, the anchor bolt 50 is inserted into the hole 23 of the roof-side fixing bracket 20 and fixed using a nut or the like.

  On the other hand, the roof-side fixing bracket 20 for mounting the front-side mounting bracket 30 for the rear solar cell module 10b is fixed to the flat roof surface with an adhesive or the like without using the anchor bolt 50, for example. Thus, the number of anchor bolts 50 provided on the flat roof can be reduced. At the time of attaching such a roof-side fixing bracket 20, waterproofing of the land roof surface may be performed. The waterproofing work is performed using a waterproof sheet, a waterproof seal, a waterproof nut, or the like. In addition, you may make it perform the waterproofing construction of a land roof surface in the case of roof construction. However, you may make it fix the roof side fixing metal fitting 20 for attaching the front side attachment metal fitting 30 for the solar cell module 10b of the rear side using the anchor bolt 50. FIG.

  Next, the front mounting bracket 30 and the rear mounting bracket 40 are fixed to the fixed roof side fixing brackets 20 with bolts, respectively. At this time, the long hole 24 formed in the mounting bracket mounting surface 22 of the roof side fixing bracket 20 and the long hole 33 formed in the base 31 of the front mounting bracket 30 are aligned and fixed with bolts. . Similarly, the long hole 24 formed in the mounting bracket mounting surface 22 of the roof side fixing bracket 20 and the long hole 44 formed in the base 41 of the rear mounting bracket 40 are aligned with bolts. Fix it. In this case, since attachment is performed using the long holes 24, 33, 44 formed in the respective metal fittings 20, 30, 40, it is possible to give a certain degree of freedom in workability, and it is temporarily fixed on the roof side. Even if the metal fitting 20 is not dimensioned as planned, or the attachment position of the roof-side fixing metal fitting 20 on the flat roof surface is slightly shifted in the front-rear direction, the attachment can be performed. Therefore, when attaching the roof-side fixing bracket 20 (anchor bolt 50) to the flat roof surface, it is attached with care so that only the position in the left-right direction is not displaced.

  Subsequently, as shown in FIG. 1, the roof-side fixing bracket 20 to which the rear mounting bracket 40 for the front solar cell module 10a is mounted and the front mounting bracket 30 for the rear solar cell module 10b are mounted. The roof-side fixing bracket 20 is connected using the wiring bracket 60. The wiring metal fitting 60 is a reinforcing connecting tool for connecting the roof-side fixing metal fittings 20 and 20 of the solar cell modules 10a and 10b adjacent to each other in the front-rear direction. As shown in FIGS. 11 and 12, the wiring metal fitting 60 is provided with a cable support plate 62 that protrudes laterally (to the left in FIG. 11) on a metal fitting body 61 that is elongated in the front-rear direction of an inverted L shape when viewed from the front. Is formed. Further, a locking portion 63 described later is provided at the front end of the metal fitting body 61, and a hole (not shown) is provided at the rear end portion of the metal fitting body 61. The length of the wiring bracket 60 in the front-rear direction is such that the roof-side fixing bracket 20 to which the rear mounting bracket 40 for the front solar cell module 10a is mounted and the front mounting bracket 30 for the rear solar cell module 10b are mounted. It changes suitably according to the distance with the roof side fixing metal fitting 20 which is. The hole provided at the rear end of the metal fitting body 61 may be a long hole that is long in the front-rear direction.

  Such a locking portion 63 of the wiring metal fitting 60 is hooked and locked to the front end surface of the roof-side fixing metal fitting 20 to which the rear mounting metal fitting 40 for the front solar cell module 10a is attached. The rear end portion of 60 is fixed with a bolt to the roof-side fixture 20 to which the front-side fixture 30 for the rear solar cell module 10b is attached. At the time of bolt fixing, a hole provided in the rear end portion of the metal fitting body 61 and a long hole 26 provided in the side surface 25 of the roof side fixing metal fitting 20 are used.

  Thus, by connecting the roof-side fixing brackets 20 and 20 of the solar cell modules 10a and 10b adjacent to each other by the wiring bracket 60, the number of anchor bolts 50 attached to the land roof can be reduced (rear side). Mechanical strength can be ensured even if the roof-side fixture 20 for attaching the front-side fixture 30 for the solar cell module 10b is fixed with an adhesive or the like. Further, when the solar cell modules 10a and 10b adjacent to each other are connected by the output cables 18 and 19 described above, the output cable is used by using the cable support member 64 attached to the cable support plate 62 of the wiring metal fitting 60. 18 and 19 are fixed to the wiring fitting 60. The wiring fitting 60 prevents the output cables 18 and 19 from being exposed to direct sunlight, prevents the output cables 18 and 19 from being deteriorated, and allows the output cables 18 and 19 to be laid out with a good appearance. .

  Next, the solar cell module 10a (the same applies to the solar cell module 10b) is attached to the front mounting bracket 30 and the rear mounting bracket 40. A hole formed in the front frame 13 of the solar cell module 10a is used for fixing the solar cell module 10a and the front mounting bracket 30. At this time, a bolt 35 having a size corresponding to the size of the hole formed in the front frame 13 is attached in advance to the inclined portion 32 of the front mounting bracket 30. Similarly, holes formed in the rear frame 14 of the solar cell module 10a are used for fixing the solar cell module 10a and the rear mounting bracket 40. Bolts 45 having dimensions corresponding to the sizes of the holes formed in the rear frame 14 are attached in advance to the inclined portion 42 of the rear mounting bracket 40.

  By attaching the solar cell module 10 to the flat roof surface as described above, there are the following advantages in addition to the advantages described above.

  Various sizes and arrangements can be considered for the solar cell module 10 installed on the flat roof surface. By preparing the required number of roof-side fixing brackets 20, front-side mounting brackets 30, and rear-side mounting brackets 40 as shown in FIGS. 7, 8, and 9 according to the size and arrangement of the solar cell modules 10, Various sizes and arrangements of the battery module 10 can be supported. That is, if the roof-side fixing bracket 20, the front-side mounting bracket 30, and the rear-side mounting bracket 40 are used, the solar cell module 10 can be mounted on the flat roof surface even when the size and arrangement of the solar cell modules 10 installed on the flat roof surface are different. Can be attached to.

  Thereby, it is not necessary to prepare a new part for various arrangements of the solar cell module 10, and the mounting parts (the roof-side fixing bracket 20, the front-side mounting bracket 30, and the rear-side mounting bracket 40) are made common. The number of parts can be reduced and the cost can be reduced. And by commonization of attachment parts, simplification of construction can be achieved and the solar cell module 10 can be attached to the flat roof surface by unified work. As a result, the construction time can be greatly shortened. In this example, four roof-side fixing brackets 20 and four of the front-side mounting bracket 30 and the rear-side mounting bracket 40 are used for one solar cell module 10. You may use above.

  Thus, by simplifying the mounting structure of the solar cell module 10, even when the solar cell module 10 is damaged and needs to be replaced, only the damaged solar cell module 10 is removed without removing the plurality of solar cell modules 10. Just replace it with a new one. In this case, the output cable 18 (19) connected to the damaged solar cell module 10 is disconnected, the damaged solar cell module 10 is removed from the front mounting bracket 30 and the rear mounting bracket 40, and a new solar cell module 10 is removed. Is attached to the front mounting bracket 30 and the rear mounting bracket 40, and the output cable 18 (19) is connected. In this manner, the damaged solar cell module 10 can be easily replaced.

  As described above, a space is created between the flat roof surface and the solar cell module 10 by the height h1 of the roof-side fixture 20. Thereby, it becomes possible to put a hand into this space and perform work, and workability at the time of construction can be improved. Moreover, since the front mounting bracket 30 and the rear mounting bracket 40 are mounted in a state of floating from the flat roof surface, it is possible to prevent water or the like from staying on the flat roof surface. Furthermore, the solar cell module 10 has its own weight, wind load, snow load, etc. applied to the flat roof surface via the front mounting bracket 30 and the rear mounting bracket 40 to prevent these loads from being applied directly to the flat roof surface. Yes.

  In the above-described example, the roof-side fixing bracket 20 and the front-side mounting bracket 30 are separated, but a component in which the roof-side fixing bracket 20 and the front-side mounting bracket 30 are integrated may be used. Moreover, although the roof-side fixing bracket 20 and the rear-side mounting bracket 40 are separated from each other, a component in which the roof-side fixing bracket 20 and the rear-side mounting bracket 40 are integrated may be used. Thereby, the number of parts can be further reduced. Further, when the solar cell modules 10a and 10b are installed side by side in front and rear (FIG. 10), the roof-side fixing bracket 20 for attaching the front side mounting bracket 30 for the rear solar cell module 10b is attached to the anchor bolt 50.
