Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, an embodiment of the present invention will be described by taking a case where a plurality of solar cell modules are installed on a support material as an example. However, the present invention is not limited to this. The present invention can also be applied to a case where an arbitrary plurality of modules other than a plurality of solar cell modules are installed on a support material.
(Embodiment of fixing bracket)
FIG. 1 is a perspective view showing a state when the solar cell module M is installed on the folded roof 7 using the fixing bracket 10. 2 to 4 are a front view, a plan view, and a side view showing a state in which a plurality of solar cell modules M are installed in the inclination direction (flow direction) of the folded plate roof 7 using the fixing bracket 10.

  The solar cell module M has, for example, a flat rectangular parallelepiped shape as shown in FIG. In the present invention, the shape and configuration of the solar cell module M are not limited, but the solar cell module M is typically a rectangular solar cell module body including a plurality of solar cells arranged in a matrix ( (Not shown) and a holding frame (not shown) for holding the solar cell module body.

  The folded plate roof 7 is constructed by laying a plurality of metal plates bent into a valley having a certain width on a roof base material. On the folded plate roof 7, peaks are formed at both ends of the inverted trapezoidal valley, and a goby joint is bent at the ends of the peaks. Adjacent mountain parts are placed on the upper surface of a tight frame fixed to the roof base, and a goby joint is wound around a suspension fixed to the tight frame to form the goby part 14.

  The base tool 36 is fixed on the folded plate roof 7 so as to sandwich the goby portion 14. As the base tool 36, any known type of base tool can be used.

  The vertical member 4 as a support member for supporting the plurality of solar cell modules M is fixed on the folded plate roof 7 by a base tool 36. The vertical member 4 can be formed of a long frame. The vertical member 4 is arranged along the flow direction of the roof at the mountain portion of the folded plate roof. The length of the vertical member 4 can be changed.

  The fixing bracket 10 is a fixing bracket for fixing the solar cell modules (for example, the solar cell module M1 and the solar cell module M2) adjacent to each other among the plurality of solar cell modules M to the vertical member 4 as a support material. .

  In addition, in embodiment mentioned above with reference to FIGS. 1-4, although the support material 4 demonstrated as what was installed on the folded-plate roof 7, this invention is not limited to this. The support member 4 may be installed on an arbitrary roof other than the folded-plate roof. In the above-described embodiment, the support member 4 has been described as a vertical member installed in the inclination direction (flow direction) of the roof, but the present invention is not limited to this. The support member 4 may be a cross member installed in a direction orthogonal to the flow direction of the roof. Or the support material 4 may be installed in arbitrary places (for example, the ground) other than a roof.

  5 is an enlarged view of a part of FIG. 2 (part related to the fixing bracket 10), and FIG. 6 is an enlarged view of a part of FIG. 4 (part related to the fixing bracket 10).

  The solar cell module M1 and the solar cell module M2 are adjacent to each other along the roof inclination direction (flow direction) indicated by an arrow in FIG. In the following description, the upstream side of the roof inclination direction (flow direction) is referred to as “water-side”, and the downstream side of the roof inclination direction (flow direction) is referred to as “water-side”.

  The fixing metal fitting 10 includes a first metal fitting 11 that can be fixed to the solar cell module M1, and a second metal fitting 12 that can be fixed to the solar cell module M2. Each of the first metal fitting 11 and the second metal fitting 12 has a substantially U-shaped cross section.

  As shown in FIG. 6, the first metal fitting 11 includes an upper piece 16, a lower piece 17, and a vertical piece 18 that connects the upper piece 16 and the lower piece 17. The first metal fitting 11 is formed of a frame-like long cross member. In the example shown in FIG. 6, an inclined piece 19 that is inclined obliquely upward is formed at the tip of the lower piece 17, but the tip of the lower piece 17 may be horizontal.

  As shown in FIG. 6, the second metal fitting 12 includes an upper piece 21, a lower piece 22, and a vertical piece 23 that connects the upper piece 21 and the lower piece 22. The second metal fitting 12 is formed of a frame-like long cross member.

  The upper piece 16 of the first metal fitting 11 is fixed to the lower surface of the water-side end of the solar cell module M1. Such fixing is performed by a fixing tool 20 such as a bolt and nut, for example. When the upper piece 16 of the first metal fitting 11 is fixed to the lower surface of the water-side end of the solar cell module M1, the upper piece 16 of the first metal fitting 11 is the water-side end of the solar cell module M1. However, the lower piece 17 of the first metal fitting 11 protrudes from the water-side end of the solar cell module M1 toward the water side.

  The upper piece 21 of the second metal fitting 12 is fixed to the lower surface of the underwater end portion of the solar cell module M2. Such fixing is performed by a fixing tool 29 such as a bolt and nut, for example. In the case where the upper piece 21 of the second metal fitting 12 is fixed to the lower surface of the underwater end portion of the solar cell module M2, the upper piece 21 of the second metal fitting 12 is located on the underwater side of the solar cell module M2. Although it does not protrude from the end portion toward the underwater side, the lower piece 22 of the second metal fitting 12 protrudes from the underwater end portion of the solar cell module M2 toward the underwater side.

  As shown in FIG. 6, the lower piece 17 of the first metal fitting 11 is fixed to the upper surface of the longitudinal member 4 via the spacer 8. Such fixing is performed by a fixing tool 25 such as a bolt and nut, for example.

  The spacer 8 is arranged between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4, and bolts are passed through holes formed in the lower piece 17, the spacer 8, and the vertical member 4. The lower piece 17 of the first metal fitting 11 is fixed to the upper surface of the vertical member 4 via the spacer 8 by screwing a nut into a bolt that penetrates the hole. In this way, when the lower piece 17 of the first metal fitting 11 is fixed to the upper surface of the vertical member 4 via the spacer 8, it is between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4. A gap 6 corresponding to the thickness of the spacer 8 is formed. Thus, the gap 6 is formed between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4. The gap 6 formed in this way is not shown in FIG. 6, but is shown in FIG. As shown in FIG. 10B, the second metal fitting 12 is configured such that the lower piece 22 of the second metal fitting 12 can be inserted into the gap 6.

  As the spacer 8, a ring-shaped washer, a U-shaped washer provided with a slit communicating with the center hole, or the like can be used.

  The thickness of the spacer 8 is arbitrary so that the lower piece 22 of the second metal fitting 12 fixed to the solar cell module M2 is inserted between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4. Can be set to a value.

  For example, the thickness of the spacer 8 can be set to be approximately the same as the thickness of the lower piece 22 of the second metal fitting 12. Alternatively, the thickness of the spacer 8 may be set slightly larger or smaller than the thickness of the lower piece 22 of the second metal fitting 12. When the thickness of the spacer 8 is set to be slightly smaller than the thickness of the lower piece 22 of the second metal fitting 12, the thickness of the spacer 8 is set to be approximately the same as the thickness of the lower piece 22 of the second metal fitting 12. Compared to the case, since the vertical dimension of the gap 6 formed between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4 is reduced, the lower piece 17 of the first metal fitting 11 is elastic (deformed). The lower piece 22 of the second metal fitting 12 fixed to the solar cell module M2 is sandwiched between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4. Will increase.

  In the example shown in FIG. 6, a hole for inserting a bolt is provided in the vicinity of the vertical piece 18 side of the lower piece 17 of the first metal fitting 11, and a fixing tool 25 such as a bolt nut and the spacer 8 pass through the hole. Has been placed. However, the position where the fixture 25 and the spacer 8 are disposed (the position in the inclination direction (flow direction) of the roof) is not limited to the position shown in FIG. The position at which the fixing tool 25 and the spacer 8 are disposed (the position in the roof tilt direction (flow direction)) is a gap 6 formed between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4. As long as the tip of the lower piece 22 of the second metal fitting 12 can be inserted, it can be at any position. For example, the spacer 8 may be arranged at the center in the width direction of the lower piece 17 of the first metal fitting 11. In this case, the tip of the lower piece 22 of the second metal fitting 12 is inserted into the gap formed between the vertical member 4 and the tip of the lower piece 17.

  In the example shown in FIG. 6, the lower piece 22 of the second metal fitting 12 is vertically aligned with the lower piece 17 of the first metal fitting 11 with the tip of the lower piece 22 of the second metal fitting 12 in contact with the spacer 8. It is sandwiched between the upper surface of the material 4. In this case, once the tip of the lower piece 22 of the second metal fitting 12 comes into contact with the spacer 8, it does not advance any further, so that the width dimension of the gap 3 between the solar cell module M1 and the solar cell module M2 is the desired width. By predetermining the position where the tip of the lower piece 22 of the second metal fitting 12 contacts the spacer 8 so as to have a dimension (for example, 5 mm), the space between the solar cell module M1 and the solar cell module M2 is determined. The width dimension of the gap 3 can be easily set to a desired width dimension (for example, 5 mm). Thereby, since the operator can eliminate the trouble of adjusting the width dimension of the gap 3 between the solar cell module M1 and the solar cell module M2 each time, the work efficiency of the worker can be improved. However, as long as the lower piece 22 of the second fitting 12 is inserted into the gap 6 between the lower piece 17 of the first fitting 11 and the upper surface of the longitudinal member 4, the tip of the lower piece 22 of the second fitting 12 is a spacer. It is not necessary to abut 8. For example, the lower piece 22 of the second metal fitting 12 is inserted into the gap 6 so as to avoid the spacer 8 by providing a cutout portion corresponding to the spacer 8 in the lower piece 22 of the second metal fitting 12. It may be.

  In the example shown in FIG. 6, the spacer 8 is used to form the gap 6 between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4. Here, the method of forming the gap 6 between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4 is not limited to the method using the spacer 8. As a method of forming the gap 6 between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4, any method can be adopted. For example, a method of forming the gap 6 between the lower piece 17 of the first metal piece 11 and the upper surface of the vertical member 4 using a plate material fixed to the lower surface of the lower piece 17 of the first metal piece 11, A method of forming a gap 6 between the lower piece 17 of the first metal piece 11 and the upper surface of the vertical member 4 by making a step on the lower piece 17 of the metal piece 11. A method of forming a gap 6 between the lower piece 17 of the first metal fitting 11 and the upper surface of the vertical member 4 by providing a protrusion on the lower piece 17 of the first metal fitting 11 so as to protrude toward the material 4. (For example, a method of attaching a bead or protrusion (burring) to the lower piece 17 of the first metal fitting 11) can be employed.

  Thus, the fixing bracket 10 is a solar cell without a part of the fixing bracket 10 preventing the contact between the solar cell module M1 and the solar cell module M2 between the solar cell module M1 and the solar cell module M2. The module M1 and the solar cell module M2 are configured to be able to be fixed to a support member (for example, the vertical member 4). By using the fixing bracket 10, the width dimension of the gap 3 between the solar cell module M1 and the solar cell module M2 can be reduced as compared with the case of using the conventional fixing bracket. For example, the width dimension of the gap 3 can be about 3 mm to about 7 mm, preferably about 5 mm. In addition, by using the fixture 10, technically, the solar cell module M1 and the solar cell module M2 are in contact with each other (that is, in the state where the width dimension of the gap 3 is substantially zero). Although it is possible to fix the battery module M1 and the solar cell module M2 to a support material (for example, the vertical member 4), it is not practical. Because each of the solar cell module M1 and the solar cell module M2 may thermally expand, the solar cell module M1 and the solar cell module M2 are separated by a desired distance (for example, 5 mm) in preparation for thermal expansion. This is because it is preferable to fix the solar cell module M1 and the solar cell module M2 to the support member (for example, the vertical member 4).

  As described above, by using the fixing bracket 10, the width dimension of the gap 3 between the solar cell module M1 and the solar cell module M2 can be reduced as compared with the case of using the conventional fixing bracket. Thereby, since the snow accumulated on the solar cell modules M1 and M2 slides and falls easily on the solar cell modules M1 and M2, it is possible to prevent the photovoltaic power generation system from being damaged or damaged due to the weight of the accumulated snow. Can do. Moreover, since the number of solar cell modules that can be installed per unit area can be increased, the area of the place where the solar cell modules are installed can be used effectively.

  In one embodiment of the present invention, the fixture 10 is fixed to the solar cell module M2 with a first portion (for example, the first fixture 11) that can be fixed to the solar cell module M1. And a second portion (for example, the second metal fitting 12). The first portion is configured such that the first portion can be fixed to a support member (for example, the longitudinal member 4). The second part can be inserted into a gap formed between a part of the first part and the surface of the support member (for example, the vertical member 4). It is configured.

In the embodiment described above with reference to FIGS. 5 to 6, each of the first metal fitting 11 and the second metal fitting 12 has been described as having a substantially U-shaped cross section. The invention is not limited to this. The cross-sectional shape of the first metal fitting 11 and / or the second metal fitting 12 may be a shape other than a substantially U shape (for example, a substantially crank shape, a substantially Z shape, etc.).
(Embodiment of a method for fixing a plurality of modules M to a support material)
Hereinafter, with reference to FIGS. 7 to 9, a method for fixing the plurality of solar cell modules M to the vertical member 4 as a support member using the fixing bracket 10 will be described.

  On the eaves side of the folded roof 7, as shown in FIG. 7, the eaves side end of the solar cell module M <b> 1 is fixed on the vertical member 4 using the third metal fitting 51. The third metal fitting 51 includes an upper piece 52, a lower piece 53, and a vertical piece 54 that connects the upper piece 52 and the lower piece 53. The third metal fitting 51 has a substantially U-shaped cross section.

  The upper piece 52 of the third metal fitting 51 is fixed to the lower surface of the eaves side end portion of the solar cell module M1 by a fixture 55 such as a bolt and nut, and the lower piece 53 of the third metal fitting 51 is fixed to the eave side edge of the vertical member 54. The part is fixed by a fixing tool 55 such as a bolt and nut. When fixing the 3rd metal fitting 51 to the lower surface of the solar cell module M1, it is good to fix the cover 60 to the lower surface of the eaves side edge part of the module M. The cover 60 has an inclined piece 61 inclined obliquely downward from the eaves side end of the solar cell module M1. The inclined piece 61 prevents rainwater from being applied to the entire exposed surface of the third metal fitting 51.

  Next, as shown in FIG. 8, the first metal fitting 11 is fixed to the water-side end (ridge-side end) of the solar cell module M1 disposed on the eaves side by a fixture 20 such as a bolt and nut. Thereby, the 1st metal fitting 11 is fixed so that the lower piece 17 of the 1st metal fitting 11 may protrude toward the water side.

  Next, the solar cell module M2 adjacent to the solar cell module M1 is disposed on the vertical member 4.

  Here, the upper piece 16 of the first metal fitting 11 is fixed to the lower surface of the water-side end portion of the solar cell module M2 so that the lower piece 17 of the first metal fitting 11 protrudes to the water upper side. Further, the upper piece 21 of the second metal fitting 12 is fixed to the lower surface of the underwater end portion of the solar cell module M2 so that the lower piece 22 of the second metal fitting 12 protrudes under the water.

  In this way, the module M2 in which the first metal fitting 11 and the second metal fitting 12 are fixed to the opposite water-side and water-side ends of the solar cell module M2 is replaced with the solar cell module M1 fixed to the eaves side. It arrange | positions on the vertical member 4 in the ridge side.

  Next, the solar cell module M2 was slid toward the solar cell module M1 side, and formed between the lower piece 17 of the first metal fitting 11 fixed to the solar cell module M1 and the upper surface of the vertical member 4. The lower piece 22 of the second metal fitting 12 fixed to the solar cell module M2 is inserted into the gap 6 (see FIGS. 8 and 9).

  By sliding and inserting the lower piece 22 of the second metal fitting 12 into the gap 6 until the tip of the lower piece 22 of the second metal fitting 12 comes into contact with the spacer 8, the water-side end of the solar cell module M1 and the solar battery A gap 3 having a desired size is formed between the lower end of the module M2.

  Thereafter, the second metal fitting 12 fixed to the solar cell module M2 is fixed to the vertical member 4.

  Similarly, another module M3 to which the first metal fitting 11 and the second metal fitting 12 are fixed is installed on the vertical member 4 on the water upper side, and is slid toward the module M2 on the lower water side, thereby causing the vertical member 4 to slide. To fix. In this way, a plurality of modules M1, M2, and M3 can be installed and fixed on the vertical member 4 as a support member.

  According to this method, the work of fixing the second metal fitting 12 of the solar cell module M2 to the vertical member 4 using a fixing tool such as a bolt and nut is not required, so that the workability is excellent.

  In particular, even when the vertical space between the folded plate roof 7 and the solar cell modules M1, M2, and M3 is narrow and work cannot be performed under the solar cell modules M1, M2, and M3, the solar cell modules M1, M2, and M3 Since the plurality of solar cell modules M1, M2, and M3 can be fixed to the vertical member 4 simply by installing them on the vertical member 4 from the upper side and sliding them in the horizontal direction, workability is improved.

  Further, since the gaps between the plurality of solar cell modules can be made very narrow, it is not necessary to attach a cover for closing the large gap formed between the plurality of solar cell modules as in the prior art.

  In addition, in embodiment shown by FIG.6, FIG.8, FIG.9, although the bowl-shaped cover 26 which receives the rain water which fell through the gap | interval 3 formed between adjacent solar cell modules M1 and M2 is provided, The cover 26 is not always necessary.

  As the cover 26, a cover having a horizontal piece 27 and a vertical piece 28 formed in a substantially L shape can be used. The cover 26 is disposed on the side surface side of the vertical piece 18 of the first metal fitting 11, and is attached to the vertical piece 18 of the first metal fitting 11 by a fixture such as a bolt and nut fixed to the vertical piece 18 of the first metal fitting 11. It is fixed. The tip of the horizontal piece 27 of the cover 26 is bent slightly upward to form an inclined piece 30.

  The horizontal piece 27 of the cover 26 is located vertically below the gap 3 between the solar cell module M1 and the solar cell module M2. The cover 26 forms a ridge, receives rainwater flowing from the gap 3 between the solar cell module M1 and the solar cell module 2 by the cover 26, and rainwater in the longitudinal direction of the cover 26 (direction perpendicular to the flow direction of the roof). Can be induced and discharged.

  Furthermore, as shown in FIG. 5, the cross member joint 46 may be fixed to the first metal fitting 11. When the cross member joint 46 is fixed, the fixing members 10 fixed to the lower surfaces of the modules M1 and M1 adjacent to each other in the roof girder direction by the cross member joint 46 are connected to each other. The connection strength of each installed module M1 is improved. The cross member joint 46 is formed in an L shape in cross section and has a vertical piece 47 and a horizontal piece 48.
