A solar power generation roof 1 including a solar panel stand as a solar panel support stand according to one embodiment of the present disclosure will be described in detail below with reference to the drawings. In this embodiment, the ridge side (upper side) of the roof is referred to as the ridge side X1, and the eave side (lower side) of the roof is referred to as the eave side X2.

As shown in FIG. 1, the solar power generation roof 1 of this embodiment comprises a solar panel support structure 10 and multiple solar power generation panels 70 (solar panels). The solar panel support structure 10 is a structure for mounting the solar power generation panels 70 on a roof body 12. The multiple solar power generation panels 70 are arranged along the inclination direction of the roof body 12. The roof body 12 slopes downward from the ridge side X1 on the upper side to the eaves side X2 on the lower side.

As shown in Figures 1 to 3B, the solar panel support structure 10 comprises a base material 11, a number of slates 121 (roofing materials) that constitute the roof body 12, a number of solar panel stands 20 (solar panel support stands), and an eave-side lower end inclined cover 60.

The base material 11 extends in the direction of inclination at a predetermined inclination angle. The inclination angle of the base material 11 becomes the inclination angle of the roof of the building. The base material 11 serves as a base for the multiple slates 121 that make up the roof body 12. The base material 11 is formed, for example, by placing a waterproof sheet on top of a sheathing board. The base material 11 is placed, for example, on top of multiple rafters (not shown) that form the framework of the roof of the building.

As shown in Figures 2 to 3B, the roof body 12 is placed above the base material 11. The roof body 12 is composed of multiple slates 121 (roofing material). In this embodiment, the slates 121 are formed from planar plate material. The multiple slates 121 are arranged continuously in the inclined direction on the base material 11, overlapping with a predetermined overlap width.

The multiple slates 121 are arranged in succession, with the end of the ridge side X1 (upper side) of one slate 121 overlapping the upper surface of the end of the eaves side X2 (lower side) of another slate 121. Each of the multiple slates 121 is fixed to the base material 11.

As shown in Figures 2 to 3B, at the boundary where two slates 121 overlap in the roof body 12, the slate 121 on the ridge side X1 (upper side) is located at the upper level, and the slate 121 on the eaves side X2 (lower side) is located at the lower level, forming a step 13. The step 13 is formed by the end face of the eaves side X2 in the inclined direction of the upper slate 121, and falls from the end of the eaves side X2 of the roof body 12 on the upper surface of the slate 121.

The solar panel mount 20 is placed on the roof body 12 as shown in Figures 2 to 3B. The solar panel mount 20 is used to fix the solar power generation panel 70 to the roof body 12. The solar panel mount 20 is fixed onto the roof body 12 and the base material 11. The solar panel mount 20 also supports the solar power generation panel 70.

As shown in Figures 1 and 2, multiple solar panels 70 are arranged side by side in the inclination direction of the roof body 12 of the solar roof 1, and multiple panels are arranged side by side in a direction perpendicular to the inclination direction of the roof body 12, and are fixed and supported by multiple solar panel stands 20.

The multiple solar panel mountings 20 are composed of a ridge end support 30, multiple intermediate support stands 40, and an eave end support stand 50. The ridge end support stand 30, the multiple intermediate support stands 40, and the eave end support stand 50 are arranged side by side in the inclination direction of the roof body 12.

As shown in Figures 2 and 3A, the ridge side end support base 30 is arranged on the end side of the ridge side X1 (upper side) in the tilt direction of the roof body 12. The ridge side end support base 30 supports the end of the ridge side X1 of the solar power generation panel 70 arranged on the eaves side X2 relative to the ridge side end support base 30. The ridge side end support base 30 includes a fixing bracket 31, a panel holding bracket 32, a resin eaves side end cover material 33 (cover material), and a resin ridge side end cover material 34.

As shown in Figures 2 and 3A, the multiple intermediate support stands 40 are arranged on the eaves side X2 of the ridge side end support stand 30. The intermediate support stand 40 supports the eaves side X2 end of the solar power generation panel 70 arranged on the ridge side X1 relative to the intermediate support stand 40, and also supports the ridge side X1 end of the solar power generation panel 70 arranged on the eaves side X2 relative to the intermediate support stand 40. The intermediate support stand 40 includes a fixing bracket 41, a panel holding bracket 42, and a resin eaves side end cover material 43 (cover material).

As shown in Figures 2 and 3B, the eaves side end support base 50 is arranged on the end side of the eaves side X2 (lower side) in the inclination direction of the roof body 12. The eaves side end support base 50 supports the end of the eaves side X2 of the solar power generation panel 70 arranged on the ridge side X1 relative to the eaves side end support base 50. As shown in Figures 4 and 5, the eaves side end support base 50 includes a fixing bracket 51, a panel holding bracket 52, and a resin eaves side end cover material 53 (cover material).

As shown in FIG. 2, the intermediate support base 40A, which is located on one side in the left-right direction, has a bendable portion 433 of the eaves-side end cover material 43 bent and a wiring attachment member 45 attached as shown in FIG. 6. As shown in FIG. 2, the ridge-side end support base 30A, which is located on one side in the left-right direction, has a bendable portion (not shown) of the eaves-side end cover material 33 bent and a wiring attachment member 35 attached as shown in FIG. 2.

The ridge end support 30, the multiple intermediate support stands 40, and the eaves end support stand 50 are positioned in the inclination direction of the roof body 12, either straddling or not straddling the steps 13 at predetermined positions in the multiple slates 121, as shown in Figures 2 to 3B.

When the ridge end support 30, intermediate support 40, and eaves end support 50 are arranged across a step 13 at a predetermined position in multiple slates 121, a spacer 14 of the same thickness as the step 13 is arranged on the upper surface of the lower slate 121. In this way, the spacer 14 is arranged so as to be flush with the upper surface of the upper slate 121, thereby responding to the step 13 of the slate 121. The ridge end support 30, intermediate support 40, and eaves end support 50 are attached to a portion where there is no step 13, or are attached across the spacer 14 arranged to respond to the step 13 and the slate 121.

The fixing brackets 31, 41, 51 and panel retaining brackets 32, 42, 52 in the ridge-side end support base 30, intermediate support base 40, and eaves-side end support base 50 are of the same configuration. Therefore, the configuration of the eaves-side end support base 50 will be mainly described, and the different configurations will be described separately. In describing the configuration of the intermediate support base 40, for each configuration that is similar to each configuration of the eaves-side end support base 50, the most significant digit of the code for each configuration of the eaves-side end support base 50 may be changed from "5" to "4" and the description thereof may be omitted.

As shown in Figures 2 and 3B, in the eaves-side end support base 50, the fixing bracket 51 is composed of a shaped member that extends in the inclination direction of the roof body 12. The fixing bracket 51 is fixed to the roof body 12 in a state inclined in the inclination direction of the roof body 12. The fixing bracket 51 supports the photovoltaic panel 70.

As shown in Figures 4 and 5, the fixing bracket 51 has a hollow portion 511 extending in the inclination direction of the roof body 12, a recess 512 recessed from the upper part of the hollow portion 511 and extending in the inclination direction of the roof body, a pair of upper grooves 513 recessed on both lateral sides in the width direction at the upper part of the recess 512, and a pair of lower end width direction extension plates 514 extending on both lateral sides in the width direction of the hollow portion 511 at the lower end of the hollow portion 511.

The pair of upper grooves 513 are spaced apart in a direction perpendicular to the inclination direction of the roof body 12 at the top of the fixing bracket 51. The pair of upper grooves 513 are formed in the shape of grooves facing each other with the inside open in the direction perpendicular to the inclination direction of the roof body 12 at the top of the hollow portion 511 of the fixing bracket 51.

Both ends of the back plate member 515 are placed in the pair of upper grooves 513. The back plate member 515 is fixed to a panel retaining bracket 52 (described later) that is placed on the upper side of the fixing bracket 51 by a bolt 516 extending in the vertical direction. Since both ends of the back plate member 515 are placed in the pair of upper grooves 513 and configured to be movable in the tilt direction of the roof body 12, the panel retaining bracket 52 fixed to the back plate member 515 can slide in the tilt direction of the roof body 12.

As shown in FIG. 3B, the head 516a of the bolt 516 that secures the panel retaining bracket 52 and the back plate member 515 is disposed in the recess 512 of the hollow portion 511. The solar panel 70 is disposed on the upper surface of the fixing bracket 51. The recess 512 is formed to extend in the inclination direction of the roof body 12. The recess 512 constitutes a drainage flow path that allows water to flow to the end side of the eaves side X2 of the roof body 12.

As shown in Figures 3A to 5, the panel clamping bracket 52 is positioned above the fixing bracket 51 at a distance sufficient to hold down the solar panel 70 in the thickness direction. The panel clamping bracket 52 extends a predetermined length in a direction perpendicular to the inclination direction of the roof body 12.

As shown in Figures 4 and 5, the panel retaining bracket 52 has a U-shaped member 521 with a U-shaped cross section that extends a predetermined length in a direction perpendicular to the inclination direction of the roof body 12, a ridge side protruding piece 522 that protrudes from the end of the ridge side X1 of the U-shaped member 521 toward the ridge side X1, and an eaves side protruding piece 523 that protrudes from the end of the eaves side X2 of the U-shaped member 521 toward the eaves side X2. The bottom panel of the U-shaped member 521 is fixed to the back panel member 515 placed in the pair of upper grooves 513 by bolts 516.

As shown in FIG. 3B, in the panel clamping bracket 52, the eaves side protruding piece 523 holds the eaves side support member 528 arranged on the eaves side X2 of the panel clamping bracket 52, and the ridge side protruding piece 522 holds the end of the eaves side X2 of the photovoltaic panel 70 arranged on the ridge side X1 of the panel clamping bracket 52 from above. The eaves side support member 528 is formed in an L-shape and is fastened together with the bolt 516 that secures the panel clamping bracket 52 and the roof body 12.

A resin eaves side lower end inclined cover 60 is attached to the eaves side support member 528. The eaves side lower end inclined cover 60 is attached to the eaves side X2 of the solar power generation panel 70 arranged at the furthest eaves side X2 in the inclination direction of the roof body 12. As shown in FIG. 3B, the eaves side lower end inclined cover 60 has a downwardly sloping surface that slopes downward from the ridge side X1 toward the eaves side X2, and is arranged at the eaves edge of the solar power generation roof 1. The eaves side lower end inclined cover 60 extends in a direction perpendicular to the inclination direction of the roof body 12 of the solar power generation roof 1. The eaves side lower end inclined cover 60 covers the eaves edge of the solar power generation panel 70. This enhances the design of the eaves edge of the solar power generation panel 70.

As shown in Figures 4 and 5, in the eaves side end support base 50, the eaves side end cover material 53 is attached to the end of the eaves side X2 of the roof body 12 (the lower end in the inclination direction of the roof body 12) of the fixing bracket 51. The eaves side end cover material 53 covers most of the opening at the end of the eaves side X2 of the fixing bracket 51. The resin eaves side end cover material 53 is formed from a resin material.

As shown in FIG. 3B, the eaves side end cover material 53 is positioned at the end of the fixing bracket 51 on the eaves side X2 of the roof body 12, at a position with a gap above the top surface of the bottom plate 511a of the hollow portion 511, and is attached to the fixing bracket 51 at a position with a gap above the top surface of the slate 121 of the roof body 12. This allows water flowing over the top surface of the bottom plate 511a of the hollow portion 511 to be drained through the gap to the lower side in the inclination direction of the roof body 12.

Here, in the solar power generation roof 1, as shown in FIG. 2, cables 301, 401 (wiring material) for electrical wiring are wired on the upper surface of the roof body 12. The solar panel mounting 20 (ridge end support 30, multiple intermediate support 40, eave end support 50) is fixed to the upper surface of the roof body 12. Therefore, the cables 301, 401 may come into contact with the ends of the solar panel mounting 20 (ridge end support 30, multiple intermediate support 40) or may come into contact with the corners of the solar panel mounting 20 (ridge end support 30, multiple intermediate support 40) by being bent and wired.

In contrast, in the ridge side end support base 30 and the intermediate support base 40, the eaves side end cover materials 33, 43 are formed from a resin material. As a result, even if the cables 301, 401 (wiring material) come into contact with the ends of the eaves side X2 of the ridge side end support base 30 and the intermediate support base 40, or if the cables 301, 401 (wiring material) bent at the corners of the ends of the eaves side X2 of the ridge side end support base 30 and the intermediate support base 40 come into contact, damage to the cables 301, 401 can be suppressed because the eaves side end cover materials 33, 43 are formed from a resin material.

As shown in Figures 4 and 5, in the eaves side end support base 50, the eaves side end cover material 53 has a surface plate portion 531 and a protruding portion 532 that protrudes from the back surface of the surface plate portion 531 toward the fixing bracket 51.

The surface plate portion 531 is formed in a rectangular plate shape and is arranged at the end of the eaves side X2 of the roof body 12 in the fixing bracket 51. The surface plate portion 531 is arranged so as to cover the upper part of the lower end surface of the hollow portion 511 of the fixing bracket 51. The protruding portion 532 is formed in a U-shape that opens downward and is inserted into the end of the eaves side X2 of the fixing bracket 51. When the protruding portion 532 is inserted into the end of the eaves side X2 of the fixing bracket 51, it is fixed to the upper surface of the bottom of the recess 512 of the fixing bracket 51 by the screw 532a. As shown in FIG. 3B, the head 532b of the screw 532a is arranged on the eaves side X2 of the head 516a of the bolt 516 in the recess 512 and functions as a stopper to prevent the slidable bolt 516 from coming out.

As shown in FIG. 5, the surface plate portion 531 has a pair of foldable portions 533, a pair of folding grooves 534, and an upper drainage opening 535 (drainage opening).

As shown in FIG. 4, the upper drainage opening 535 is formed in a rectangular shape at the top of the surface plate portion 531, penetrating the surface plate portion 531 in the thickness direction. The bottom edge 535a of the upper drainage opening 535 is formed at the same height as the upper surface of the bottom of the upper recess 512 of the hollow portion 511 of the fixing bracket 51. This allows water flowing downstream in the tilt direction of the roof body 12 along the upper surface of the bottom of the upper recess 512 of the hollow portion 511 to be drained outside the eaves side end support base 50.

The foldable parts 533 are arranged midway up and down at both left and right ends of the surface plate 531 and are formed into a rectangular plate shape extending up and down. The pair of foldable parts 533 are connected to both left and right ends of the surface plate 531 via folding grooves 534.

The folding groove 534 is formed, for example, from the viewpoint of ease of folding, in the shape of a groove with a triangular cross section recessed from the surface side of the surface plate portion 531. The pair of foldable portions 533 can be folded along the folding groove 534 at both ends in the width direction of the surface plate portion 531, so that they can be folded in the folding groove 534 without being removed from the eaves side end cover material 53. Because the eaves side end cover material 53 is formed from a resin material, it can be easily folded in the folding groove 534.

When the eaves side end cover material 53 is attached to the fixing bracket 51, the pair of bendable sections 533 are provided at positions where the vertical plate 511b (see FIG. 5) of the hollow section 511 of the fixing bracket 51 is disposed on the back side. The bendable sections 533 can be bent so that the end (part) of the eaves side X2 of the vertical plate 511b of the hollow section 511 of the fixing bracket 51 is exposed.

Here, in the intermediate support base 40A, as shown in Figures 6 and 7, after bending the bendable portion 433 from the eaves side end cover material 43 without removing it from the eaves side end cover material 53, the end of the eaves side X2 of the vertical plate 411b of the hollow portion 411 of the fixing bracket 41 is exposed. Then, the wiring attachment member 45 can be attached to the end of the eaves side X2 of the vertical plate 411b of the hollow portion 411 of the fixing bracket 41.

As shown in FIG. 6, in the intermediate support base 40A, the wiring attachment member 45 is attached to the end of the eaves side X2 of the vertical plate 411b of the hollow portion 411 of the fixing bracket 41 at the portion where the bendable portion 433 of the eaves side end cover material 43 is bent and a part of the end of the eaves side X2 of the fixing bracket 41 is exposed. As shown in the upper and lower views of FIG. 7, by bending the bendable portion 433 and attaching the wiring attachment member 45, when the cable 401 is bent and placed at the corner of the intermediate support base 40A, the cable 401 can be easily fixed to the wiring attachment member 45 using a cable tie 402 (see FIG. 6). Since the wiring attachment member 45 is attached to the end of the eaves side X2 of the vertical plate 411b of the hollow portion 411 of the fixing bracket 41, the end of the eaves side X2 of the vertical plate 411b of the hollow portion 411 of the fixing bracket 41 is covered and difficult to see from the outside.

As shown in the lower diagram of FIG. 7, the wiring attachment member 45 has a metal fixing metal clip material 451 made of metal and an external resin member 452 made of resin. The fixing metal clip material 451 is formed in a clip shape so as to clamp the vertical plate 411b of the hollow portion 411 of the fixing bracket 41. Because the fixing metal clip material 451 is made of metal, it can be firmly fixed to the vertical plate 411b of the hollow portion 411 of the fixing bracket 41.

The external resin member 452 has a covering portion 453 and a wiring fixing portion 454. The covering portion 453 is arranged outside the fixing metal clip material 451 so as to cover the outer surface of the fixing metal clip material 451. The external resin member 452 is formed from a resin material. Because the external resin member 452 constituting the outer surface of the wiring attachment member 45 is formed from a resin material, damage to the cable 401 (see FIG. 2) can be suppressed even if the cable 401 comes into contact with the external resin member 452.

As shown in the lower diagram of FIG. 7, the wiring fixing portion 454 is formed with a communication portion 455 that vertically connects the upper opening 455a and the lower opening 455b, an eaves side opening 456, and a pair of slit openings 457 that are formed on the side and extend vertically and open in a slit shape, so that the cable tie 402 (see FIG. 6) can be attached. In this embodiment, as shown in FIG. 6, the cable tie 402 is attached by passing through the upper opening 455a and the lower opening 455b. Note that the cable tie 402 may also be attached by passing through the pair of slit openings 457.

When bending one of the foldable portions 433 in the eaves side end cover material 43 to attach the wiring attachment member 45, the foldable portion 533 on one side is bent in the bending groove 434 on one side in the surface panel portion 431 of the eaves side end cover material 43 from the state shown in the upper diagram of FIG. 7 to the state shown in the lower diagram of FIG. 7.

Next, at the bent portion of the bendable portion 433, as shown in the lower diagram of FIG. 7, the wiring attachment member 45 is attached to the vertical plate 411b of the hollow portion 411 of the fixing bracket 41. Then, the cable 401 is bent at the corner of the fixing bracket 41, and the cable 401 is fixed to the wiring attachment member 45 with a cable tie 402 (see FIG. 6). As a result, as shown in FIG. 6, the cable 401 can be fixed to the wiring attachment member 45 in a state where the cable 401 is bent at the corner of the fixing bracket 41. The resin eaves side end cover material 43 is formed of a resin material, and the surface of the wiring attachment member 45 is formed of a resin material, so that the cable 401 can be prevented from being damaged.

The following describes the configurations of the ridge end support base 30 and the intermediate support base 40 that differ from the eaves end support base 50.

As shown in FIG. 3A, in the panel clamp 32 of the ridge-side end support base 30, the ridge-side protruding piece 322 holds the ridge-side support member 328 arranged on the ridge side X1 relative to the panel clamp 32, and the eaves-side protruding piece 323 holds down from above the end of the ridge side X1 of the photovoltaic panel 70 arranged on the eaves side X2 relative to the panel clamp 32. The ridge-side support member 328 is formed in an L-shape and is fastened together with the panel clamp 32 by the bolt 316 that secures the panel clamp 32 and the roof body 12.

Also, as shown in FIG. 3A, in the ridge side end support base 30, the ridge side end cover material 34 is attached to the end of the ridge side X1 of the fixing bracket 31. The configuration of the ridge side end cover material 34 is the same as the eaves side end cover material 53 of the eaves side end support base 50 described above, except that the eaves side end cover material 53 of the eaves side end support base 50 described above is attached to the end of the eaves side X2 of the fixing bracket 51, while the ridge side end cover material 34 is attached to the end of the ridge side X1 of the fixing bracket 31, and therefore the explanation is omitted. Note that the ridge side end cover material 34 is arranged to cover the end of the ridge side X1 of the fixing bracket 31 of the ridge side end support base 30, so it is difficult to see from below the roof body 12. Therefore, it is not necessary to provide a ridge side end cover material on the upper end of the fixing bracket 31 of the ridge side end support base 30.

Also, as shown in FIG. 3A, in the panel clamping bracket 42 of the intermediate support base 40, the ridge side protruding piece 422 presses from above the end of the eaves side X2 of the solar power generation panel 70 arranged on the ridge side X1 relative to the panel clamping bracket 42, and the eaves side protruding piece 423 presses from above the end of the ridge side X1 of the solar power generation panel 70 arranged on the eaves side X2 relative to the panel clamping bracket 42. No ridge side end cover material is provided on the intermediate support base 40.

The above-described embodiment of the present invention provides the following effects. The intermediate support base 40 of the present embodiment includes a fixing bracket 41 that is fixed to the roof body 12 and supports the photovoltaic power generation panel 70, and a resin eaves side end cover material 43 that is attached to the end of the fixing bracket 41 on the eaves side X2 of the roof body 12. As a result, the eaves side end cover material 43 ensures design, while the eaves side end cover material 43 being made of resin can suppress damage to the cable 401 (wiring material).

In this embodiment, the eaves side end cover material 43 has a bendable portion 433 that can be bent so that a portion of the end of the eaves side X2 of the roof body 12 in the fixing bracket 41 is exposed, and a wiring attachment member 45 is attached to the fixing bracket 41 at the portion where the bendable portion 433 in the eaves side end cover material 43 is bent and a portion of the end of the fixing bracket 41 is exposed. As a result, since the eaves side end cover material 43 is made of resin, the bendable portion 433 can be easily bent, and by bending the bendable portion 433 as necessary and attaching the wiring attachment member 45 to the fixing bracket 41, the cable 401 can be easily fixed to the end of the intermediate support base 40. In addition, since the bendable portion 433 only needs to be bent and not removed, no waste is generated, making it possible to design in an environmentally friendly manner.

In addition, in this embodiment, the eaves side end cover material 43 is attached to the end of the eaves side X2 of the roof body 12 at the fixing bracket 41 at a position with a gap above the top surface of the roof body 12. This allows water flowing through the fixing bracket 41 to be drained through the gap to the lower side in the inclination direction of the roof body 12.

In addition, in this embodiment, the fixing bracket 41 is made of a shaped material and has a recess 412 that allows water to flow to the end side of the eaves side X2, and the eaves side end cover material 43 has an upper drainage opening 435 that drains water flowing through the recess 412 to the outside. This allows water flowing through the recess 412 above the hollow portion 411 to be easily drained to the outside of the intermediate support base 40 through the upper drainage opening 435.

The above describes preferred embodiments of the present disclosure, but the present disclosure is not limited to the above-described embodiments and can be modified as appropriate.

For example, in the above embodiment, the cover material (eaves side end cover material 53) is attached to the end of the eaves side X2 of the fixing bracket 51 of the eaves side end support base 50. However, this is not limited to this. The cover material may be attached to the end of the ridge side X1 of the fixing bracket 51 of the eaves side end support base 50. Similarly, the cover material may be attached to the end of the ridge side X1 of the fixing bracket 41 of the intermediate support base 40.

In addition, when the cover material is attached to the end of the ridge side X1 of the fixing bracket 51 of the eaves side end support base 50, if the roof body 12 is composed of multiple slates 121, the eaves side end cover can be attached to the fixing bracket 51 at the step 13 of the slate 121 of the roof body 12, leaving a gap from the upper surface of the lower slate 121 of the roof body 12 by the thickness of the upper slate 121. This allows the gap below the eaves side end cover to avoid the step 13 of the slate 121, so that the fixing bracket 51 of the eaves side end support base 50 can be positioned close to the step 13 of the slate 121 in the inclination direction of the roof body 12. Therefore, when attaching a solar panel support base to a roof body 12 composed of multiple slates 121, even if the installation space is small, the fixing bracket of the solar panel support base can be positioned close to the step 13 of the slate 121, thereby realizing space saving in the installation space.

In addition, in the intermediate support base 40 of the above embodiment, the wiring attachment member 45 is attached to the fixing bracket 41 by simply bending the foldable portion 433 of the eaves side end cover material 43 (cover material) without removing it, but this is not limited to this.
