Embodiments for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. For ease of understanding, XYZ coordinates orthogonal to each other are set and referred to as appropriate. The XY plane of the XYZ coordinates is a plane parallel to the roof surface R on which the pedestal 1 is installed. The Z-axis direction is a direction parallel to the height direction H from the roof surface R. Also, in the present embodiment, the eaves-to-ridge direction of the building, which is the direction from the ridge to the eaves of the building, is the same direction as the X-axis direction.

[0019] As shown in FIGS. 1 and 2, the pedestal 1 is, for example, attached to the roof surface R of a building and used to support a solar panel P as an object to be installed on the roof surface R. In the present embodiment, the building to which the pedestal 1 is attached is a house having a roof ridge and eaves. The pedestal 1 according to the embodiment includes a pedestal 10, a base 20 of the pedestal, a fixing unit 30, a receiving member 40, and a first fastener 50.

[0020] The fixing unit 30 is fixed to the receiving member 40 by the first fastener 50 and fixes the solar panel P. The fixing unit 30 has an installation target arrangement member 31, a fixing member 32, a cover 37, a receiving member for the fixing member 38, and a second fastener 39. Note that the fixing unit 30 may not have the cover 37, and the cover 37 may be replaced with the receiving member for the fixing member 38. Each component of the fixing unit 30 is formed of, for example, metal. However, it is not limited to this. Each component of the fixing unit 30 may be formed of a material other than metal. For example, each component of the fixing unit 30 may be a highly rigid material such as resin or ceramic. Also, a part of each component of the fixing unit 30 may be formed of a different material. However, it is preferable that each component of the fixing unit 30 is formed of metal, and more preferably, all of the components of the fixing unit 30 are formed of the same metal material.

[0021] In the present embodiment, the member 31 for arranging an object to be installed is a horizontal beam extending in the Y-axis direction. The member 31 for arranging an object to be installed is formed so that its XZ cross-section has a rectangular tube shape with the Z-axis direction as the longitudinal direction. The member 31 for arranging an object to be installed is formed, for example, by extrusion molding of metal. Specifically, the member 31 for arranging an object to be installed is formed, for example, by extrusion molding of aluminum. On the upper surface of the member 31 for arranging an object to be installed on the +Z side, a groove for attaching a fixing member is formed along the Y-axis direction orthogonal to the eave-ridge direction, which is the direction from the ridge of the building to the eave. Note that, in the present embodiment, the member 31 for arranging an object to be installed is a horizontal beam extending in a direction orthogonal to the eave-ridge direction. However, it is not limited to this. The member 31 for arranging an object to be installed may be a beam other than a horizontal beam. For example, the member 31 for arranging an object to be installed may be a vertical beam extending in the same direction as the eave-ridge direction. Further, the member 31 for arranging an object to be installed may be a beam other than a horizontal beam or a vertical beam extending in a direction intersecting the eave-ridge direction.

[0022] The upper surface of the member 31 for arranging an object to be installed on the +Z side is the surface on which the solar panel P is arranged. This upper surface on the +Z side is formed as a surface parallel to the YZ plane so that the solar panel P can be easily arranged.

[0023] The fixing member 32 is a metal fitting that sandwiches the solar panel P arranged on the upper surface of the member 31 for arranging an object to be installed and is fixed to the member 31 for arranging an object to be installed. The present embodiment includes three fixing members 32, and the three fixing members 32 fix two solar panels P. This fixing member 32 has side wall portions 32-1, 32-2, a connecting plate portion 32-3, and extending portions 32-4, 32-5.

[0024] The side wall portions 32-1, 32-2 are formed in a plate shape parallel to the YZ plane.

[0025] The connecting plate portion 32-3 is formed in a plate shape parallel to the XY plane. This connecting plate portion 32-3 connects the side wall portions 32-1, 32-2. A hole into which a second fastener 39 is inserted is formed in the connecting plate portion 32-3.

[0026] The extended portion 32-4 extends from the upper end (+Z-side end) of the side wall portion 32-1. The extended portion 32-4 presses any one of the solar panel P, the cover 37, and the receiving member 38 for the fixing member against the installation target arrangement member 31. A locked portion 32-4a is formed on the lower surface on the -Z side of the extended portion 32-4.

[0027] The extended portion 32-5 extends from the upper end (+Z-side end) of the side wall portion 32-2 in a direction opposite to the extending direction of the extended portion 32-4. The extended portion 32-5 presses any one of the solar panel P, the cover 37, and the receiving member 38 for the fixing member against the installation target arrangement member 31. Unlike the extended portion 32-4, a locked portion is not formed on the lower surface on the -Z side of the extended portion 32-5.

[0028] The cover 37 covers the +Y-side end of the installation target arrangement member 31. The cover 37 is made of a conductive material. The cover 37 is formed, for example, by extrusion molding of metal. Specifically, the cover 37 is formed by extrusion molding of aluminum, for example, and then a black anodizing treatment is applied to the surface to cover the silver color which is the color of aluminum itself. This cover 37 has a cover body 37-1 and a spacer 37-2.

[0029] The second fastener 39 sandwiches the solar panel P between the installation target arrangement member 31 and the fixing member 32 and fastens the installation target arrangement member 31 and the fixing member 32.

[0030] The receiving member 40 receives the fixing unit 30 from below. The receiving member 40 is formed, for example, by extrusion molding of metal. Specifically, the receiving member 40 is formed by extrusion molding of aluminum, for example.

[0031] The first fastener 50 has a bolt 51 and a nut 52. The bolt 51 is composed of, for example, a bolt or a screw. In the present embodiment, the bolt 51 of the first fastener 50 is screwed into the nut 52. However, it is not limited to this. For example, if the hole of the receiving member 40 is a threaded hole, the bolt 51 may be screwed into this hole. In this case, the nut 52 can be omitted, and the first fastener 50 is composed of only the bolt 51.

[0032] As shown in FIGS. 3(A) and 3(B), the pedestal 10 includes a sheet made of butyl rubber having a rectangular shape, and a plurality of circular mounting holes 11 and a plurality of grooves 12 extending in the Y-axis direction are formed on the surface. The plurality of grooves 12 have an anti-slip effect. Note that the shape of the pedestal 10 shown in the figure is an example and is not limited thereto. Also, the material of the pedestal 10 is not limited to butyl rubber and may be other than butyl rubber. The base mounting fastener 60 shown in FIG. 4 is inserted into the mounting hole 11.

[0033] As shown in FIGS. 4 and 5(A), the base 20 of the gantry is a T-shaped angle metal fitting in which the XZ cross-section is formed in a T shape and supports the receiving member 40 near the upper end of the T shape. The base 20 of the gantry includes a bottom plate portion 21, a standing plate portion 22, a height adjustment groove 23 (receiving member mounting portion), a protruding portion 24, and a mounting hole 25. The base 20 of the gantry has the pedestal 10 attached to the back surface of the bottom plate portion 21 and is attached to the roof surface R of the building via the pedestal 10.

[0034] The bottom plate portion 21 is a plate-shaped member processed into a rectangle, and a plurality of grooves 26 extending in the Y-axis direction are formed on the back surface. The plurality of grooves 26 have an anti-slip effect. Also, as shown in FIG. 5(B), the length L1 of the bottom plate portion 21 in the X-axis direction is longer than the length L2 in the Y-axis direction. The bottom plate portion 21 includes a first region 21a and a second region 21b. One or a plurality of mounting holes 25 are formed in each of the first region 21a and the second region 21b. In this example, three mounting holes 25 are formed in each of the first region 21a and the second region 21b.

[0035] The vertical plate portion 22 is a plate-like member erected between the first region 21a and the second region 21b of the bottom plate portion 21. The bottom plate portion 21 and the vertical plate portion 22 are integrally formed, for example, by extrusion molding of metal. Specifically, the bottom plate portion 21 and the vertical plate portion 22 are formed, for example, by extrusion molding of aluminum.

[0036] The height adjustment groove 23 (receiver member mounting portion) is a groove that extends long in the height direction H formed in the vertical plate portion 22 as shown in FIG. 4. The first fastener 50 is inserted into the height adjustment groove 23. The height adjustment groove 23 is used to adjust the position of the receiver member 40 in the height direction H.

[0037] The protruding portion 24 protrudes in the +X direction from the upper end (+Z side end) of the base 20 of the gantry. When the bolt head of the first fastener 50 catches on the protruding portion 24, it suppresses the first fastener 50 from coming off upward (+Z direction) from the height adjustment groove 23. In the present embodiment, the protruding portion 24 protrudes in the +X direction from the upper end (+Z side end) of the base 20 of the gantry. However, it is not limited to this. The protruding portion 24 may protrude in the -X direction opposite to the +X direction from the upper end (+Z side end) of the base 20 of the gantry. However, if the protruding portion 24 protrudes in the -X direction, there is a risk of interfering with the receiver member 40. For this reason, it is preferable that the protruding portion 24 protrudes in the +X direction from the upper end (+Z side end) of the base 20 of the gantry.

[0038] The mounting hole 25 includes a long hole extending in the X-axis direction. The base mounting fastener 60 is inserted through the mounting hole 25. Thereby, the base 20 of the gantry can be temporarily fixed with the base mounting fastener 60, and the position can be adjusted in the first direction D1 parallel to the X-axis direction.

[0039] A construction method of the gantry 1 configured as described above will be described with reference to the drawings.

[0040] When installing the pedestal 1 and the solar panel P on the roof surface R of a building, the worker installing the pedestal 1 on the roof surface R first places the pedestal 10 on the roof surface R as shown in Fig. 6. The pedestal 10 includes a sheet made of butyl rubber.

[0041] Next, attach the base 20 of the pedestal to the roof surface R. Specifically, first, as shown in Fig. 7, place the base 20 of the pedestal on the roof surface R, and as shown in Fig. 8, temporarily fix the base 20 of the pedestal to the roof surface R with the base attachment fasteners 60. At this time, shift the base 20 of the pedestal in the first direction D1 to adjust the installation position to the eaves side or the ridge side. After adjustment, tighten the base attachment fasteners 60 to fix the base 20 of the pedestal to the roof surface R. The number of the base attachment fasteners 60 is determined according to the required fixing strength. For example, when fixing to a rafter, use 2 for fixing. Also, when fixing to a sheathing board, use 5 for fixing.

[0042] Next, as shown in Fig. 4, temporarily fix the receiving member 40 to the base 20 of the pedestal using the first fastener 50.

[0043] Next, fit the installation target arrangement member 31 to which the solar panel P is not attached into the receiving member 40 from the +Z side (upper side).

[0044] Next, adjust the height level from the roof surface R to the upper end of the installation target arrangement member 31 so that it becomes the desired height level of the worker. Then, the worker fixes the receiving member 40 to the base 20 of the pedestal using the first fastener 50.

[0045] Next, as shown in Fig. 1, place the solar panel P, the cover 37 having the spacer 37-2, and the receiving member 38 for the fixing member on the upper surface of the installation target arrangement member 31. Then, the worker fixes the solar panel P, the cover 37, and the receiving member 38 for the fixing member to the installation target arrangement member 31 using a plurality of fixing members 32. At this time, the positions of the plurality of fixing members 32 can be adjusted along the fixing member attachment groove 31a to firmly fix the solar panel P.

[0046] As described above, as shown in FIGS. 1 and 2, the work of installing the pedestal 1 and the solar panel P on the roof surface R of the building is completed.

[0047] As described above, in the pedestal 1 and the base 20 of the pedestal according to the present embodiment, since the cross sections of the bottom plate portion 21 and the vertical plate portion 22 are formed in a T shape, a small fixing member can secure the fixing strength. Further, since the base 20 of the pedestal has the mounting hole 25 including the long hole extending in the X-axis direction, the base 20 of the pedestal can be shifted in the first direction D1 to adjust the installation position to the eaves side or the building side. Further, the vertical plate portion 22 is erected between the first region 21a and the second region 21b of the bottom plate portion 21, and one or a plurality of mounting holes 25 are formed in the first region 21a and the second region 21b, respectively. Thereby, the base 20 of the pedestal can be stably fixed to the roof surface R of the building. The vertical plate portion 22 includes the height direction adjustment groove 23 extending in the height direction, so that the position of the receiving member 40 in the height direction H can be adjusted. Further, since a plurality of grooves 26 are formed on the back surface of the bottom plate portion 21, the base 20 of the pedestal can be fixed so as not to shift with respect to the roof surface R of the building.

[0048] (Modification example) In the above-described embodiment, an example was described in which the base 20 of the pedestal is shifted in the first direction D1 to adjust the installation position to the eaves side or the gable side. At this time, as shown in FIG. 9, when the installation position of the base 20 of the pedestal is adjusted to the gable side with respect to the pedestal 10, one end portion 10a on the gable side of the pedestal 10 is at the same position as one end portion 21c on the gable side of the base 20 of the pedestal, or is arranged on the gable side of one end portion 21c on the gable side of the base 20 of the pedestal. This is realized by setting the size, shape of the pedestal 10, and the position of the mounting hole 11 of the pedestal 10 such that when the position of the mounting hole 11 of the pedestal 10 and the position on the gable side of the mounting hole 25 of the base 20 of the pedestal are aligned, one end portion 10a on the gable side of the pedestal 10 is at the same position as one end portion 21c on the gable side of the base 20 of the pedestal, or is arranged on the gable side of one end portion 21c on the gable side of the base 20 of the pedestal. By doing so, it is possible to prevent rainwater from accumulating between one end portion 21c on the gable side of the base 20 of the pedestal and the roof surface R of the building. Further, as shown in FIG. 10, when the base 20 of the pedestal is adjusted to the eaves side, the other end portion 21d on the eaves side of the base 20 of the pedestal may be arranged on the eaves side of the other end portion 10b on the eaves side of the pedestal 10. By doing so, the size of the pedestal 10 can be reduced and the cost can be suppressed.

[0049] In the base 20 of the pedestal in the above-described embodiment, an example in which the pedestal 10 has a plurality of circular mounting holes 11 was described, but the shape of the mounting holes 11 formed in the pedestal 10 is not particularly limited. For example, as shown in FIG. 11, the pedestal 10 may have a mounting hole 11 including a long hole extending in the X-axis direction. By doing so, the base 20 of the pedestal can be shifted in the first direction D1, and the installation position can be easily adjusted to the eaves side or the gable side.

[0050] The present invention can be implemented in various embodiments and modifications without departing from the broad spirit and scope of the present invention. The above-described embodiments are for explaining the present invention and do not limit the scope of the present invention.
