Description

[Technical field]

[0001] The present invention relates to a solar carport. [Background technology]

[0002] In order to increase the amount of power generated by a photovoltaic power generation system using a solar cell module, it is necessary to obtain sufficient sunlight. For this reason, solar cell modules have traditionally been installed on sunny roofs of houses, building rooftops, and the like. In recent years, solar carports have been proposed in which the roof members are made of solar cell power generation modules (for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-14764 [Patent Document 2] JP 2016-141971 A Summary of the Invention [Problem to be solved by the invention]

[0004] For example, welded H-shaped steel and welded T-shaped steel with hot-dip galvanized surfaces for corrosion protection are widely used as components for carports (e.g., rafters, purlins, and other crosspieces). However, welded H-shaped steel is produced by welding three thick plates together to form an H-shaped cross section, which makes it less lightweight and reduces transportability and workability. In addition, hot-dip galvanized steel is prone to corrosion due to rainwater, condensation, seawater splashes, and the like, which causes problems in terms of corrosion resistance.

[0005] The present invention has been made in consideration of the above-mentioned situation, and aims to provide a solar carport that is lightweight and has excellent corrosion resistance. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the present invention provides a solar carport comprising: a plurality of solar cell modules arranged in a first direction and a second direction perpendicular to the first direction; a plurality of rafter members arranged along the first direction at the lower end of each of the solar cell modules on both sides in the second direction so as to support the plurality of solar cell modules; and a plurality of water-passing members arranged along the first direction between two of the rafter members adjacent in the second direction, wherein the rafter members are lightweight steel beams, and the water-passing members have a first water-passing portion extending in the first direction between the two rafter members adjacent in the second direction and having a concave shape that opens upward, and a pair of flange portions extending outward from the upper end portions on both sides in the second direction of the first water-passing portion, and each of the pair of flange portions is clamped between the solar cell modules and the rafter members (Invention 1).

[0007] According to this invention (Invention 1), the rafter members are made of lightweight steel shaped steel, which reduces the weight of the rafter members. As a result, the transportability and workability of the rafter members are improved. In addition, moisture such as rainwater can be discharged from the carport through the first water-passing portion of the water-passing member, and the upper surface of the rafter members is protected by the flange portion of the water-passing member, which suppresses corrosion of the rafter members due to rainwater, etc.

[0008] In the above invention (Invention 1), the water-permeable member is preferably an extruded member made of aluminum or an aluminum alloy (Invention 2).

[0009] Aluminum or aluminum alloy shaped members have better corrosion resistance than steel shaped members with a hot-dip galvanized surface. Also, aluminum or aluminum alloy shaped members can be manufactured at lower cost than, for example, stainless steel shaped members. Therefore, according to this invention (Invention 2), corrosion of the water-permeable members due to rainwater, etc. is suppressed, and the cost of the water-permeable members can be reduced.

[0010] In the above inventions (Inventions 1 and 2), the water-permeable member may further have a rail portion extending in the first direction between two rafter members adjacent in the second direction and having a concave shape opening downward, and the rail portion may be configured to allow a fastening member to be inserted and held from both ends in the first direction (Invention 3).

[0011] According to this invention (Invention 3), the fastening member can be used to attach accessories, such as external lighting and rain gutters arranged along the second direction, to the rail portion.

[0012] In the above inventions (Inventions 1 to 3), the water-passing member further has a pair of second water-passing portions extending outward from the respective end portions of the pair of flange portions, and each of the pair of second water-passing portions may extend in the first direction and have a concave shape that opens upward (Invention 4).

[0013] According to this invention (Invention 4), for example, water such as rainwater that seeps out from between the solar cell module and the flange portion can be discharged via the second water passage portion of the water passage member. Effect of the Invention

[0014] According to the solar carport of the present invention, the rafter members are made of lightweight steel, which reduces the weight of the rafter members. As a result, the transportability and construction of the rafter members are improved. In addition, moisture such as rainwater can be discharged from the carport through the first water-permeable portion of the water-permeable member, and the upper surface of the rafter members is protected by the flange portion of the water-permeable member, so corrosion of the rafter members due to rainwater, etc. is suppressed.

[Figure 11] FIG. 2 is a partial perspective view of the solar carport of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the solar carport according to the present invention will be described with reference to the drawings. The embodiment described below is for the purpose of making the present invention easier to understand, and does not limit the present invention in any way.

[0017] [Solar carport] Fig. 1 is a schematic perspective view of a solar carport 100 according to one embodiment of the present invention (hereinafter simply referred to as "carport 100") as viewed from below. Fig. 2 is a schematic perspective view of the carport 100 as viewed from above.

[0018] The carport 100 comprises a plurality of solar cell modules 11, a plurality of rafter members 12, a plurality of purlin members 13, a plurality of beam members 14, and a plurality of pillars 15.

[0019] The multiple solar cell modules 11 are arranged side by side in a first direction α and a second direction β perpendicular to the first direction α. ​​The multiple rafter members 12 are arranged along the first direction α so as to support the multiple solar cell modules 11. The multiple purlin members 13 are arranged along the second direction β so as to support the multiple rafter members 12. The multiple beam members 14 are arranged along the first direction α so as to support the multiple purlin members 13. The multiple pillars 15 support the multiple beam members 14 and are erected on the ground G.

[0020] In this embodiment, the rafter member 12 is a lightweight shaped steel member. This reduces the weight of the rafter member 12. As a result, the transportability and construction of the rafter member 12 are improved.

[0021] In this embodiment, the carport 100 further includes a plurality of water-permeable members 16 arranged along the first direction α between two rafter members 12 adjacent to each other in the second direction β.

[0022] Fig. 3 shows an example of the water-permeable member 16. Fig. 3 is a schematic cross-sectional view of the water-permeable member 16 in the second direction β. Fig. 4 is a schematic cross-sectional view showing the water-permeable member 16 of Fig. 3 together with the solar cell module 11 and the rafter member 12.

[0023] As shown in FIG. 4, multiple rafter members 12 are arranged along a first direction α (direction perpendicular to the paper surface) so as to support multiple solar cell modules 11, along lower end portions 11a, 11b on both sides of the second direction β of each solar cell module 11.

[0024] As shown in Fig. 3 and Fig. 4, the water-passing member 16 has a first water-passing portion 161 that extends in the first direction α between two rafter members 12 adjacent in the second direction β and has a concave shape that opens upward, and a pair of flange portions 162 that extend outward from upper end portions 161a on both sides in the second direction β of the first water-passing portion 161. As shown in Fig. 4, each of the pair of flange portions 162 is sandwiched between the solar cell module 11 and the rafter member 12. With this structure, moisture such as rainwater can be discharged from the carport 100 through the first water-passing portion 161 of the water-passing member 16, and the upper surface portion 12a of the rafter member 12 is protected by the flange portions 162 of the water-passing member 16, so that corrosion of the rafter member 12 due to rainwater or the like is suppressed.

[0025] 4, the length of the flange portion 162 in the second direction β is preferably equal to or greater than the length of the upper surface portion 12a of the rafter member 12 in the second direction β. With such a structure, corrosion of the rafter member 12 due to rainwater, etc. may be further suppressed. The length of the flange portion 162 in the second direction β may be equal to or greater than the length of the upper surface portion 12a of the rafter member 12 in the second direction β.

[0026] The water-permeable member 16 is preferably an extruded shape made of aluminum or an aluminum alloy. For example, the extruded shape is a shape manufactured by a hot extrusion method. According to the hot extrusion method, since the extrusion is performed through a die machined into various shapes, a shape having a complex shape can be manufactured. The aluminum or aluminum alloy shape is more corrosion-resistant than a steel shape that has been subjected to hot-dip galvanization. In addition, the aluminum or aluminum alloy shape can be manufactured at a lower cost than, for example, a stainless steel shape. Therefore, when the water-permeable member 16 is an extruded shape made of aluminum or an aluminum alloy, corrosion of the water-permeable member 16 due to rainwater or the like is suppressed. This further suppresses corrosion of the rafter member 12. In addition, the cost of the water-permeable member 16 can be reduced.

[0027] 3 and 4, the water-passing member 16 may further include a rail portion 163 that extends in the first direction α between two rafter members 12 adjacent in the second direction β and has a concave shape that opens downward. The rail portion 163 is preferably configured so that the fastening member 60 can be inserted and held from both ends in the second direction β. With this structure, the fastening member 60 can be used to attach an accessory 61, such as an external light or a rain gutter arranged along the second direction, to the rail portion 163.

[0028] As shown in Figs. 3 and 4, in a cross section in the second direction β, the first water passing portion 161 and the rail portion 163 have concave shapes that face each other in the up-down direction.

[0029] 3, the rail portion 163 may have a rail groove 163a extending in the first direction α that can insert and hold the fastening member 60. The rail groove 163a may be formed by bending lower end portions 163b on both sides of the rail portion 163 in the second direction β inward.

[0030] The fastening member 60 is not particularly limited as long as it can fasten the rail portion 163 of the water-passing member 16 and the accessory 61. The fastening member 60 is, for example, a bolt having a head and a shaft, typically a hexagonal bolt 601. In the example shown in Figs. 3 and 4, the rail portion 163 has a rail groove 163a extending in the first direction α into which the shaft portion 601b of the hexagonal bolt 601 can be inserted and into which the head portion 601a of the hexagonal bolt 601 can be held. The head portion 601a of the hexagonal bolt 601 is located inside the rail groove 163a, and the shaft portion 601b of the hexagonal bolt 601 is located outside the rail groove 163a.

[0031] FIG. 5 is a schematic diagram showing an example in which an accessory 61 is attached to the rail portion 163 of the water-permeable member 16 of FIG. 3 using a fastening member 60. FIG. 6 is a side view of FIG. 5. In the example shown in FIG. 5 and FIG. 6, the accessory 61 includes a rain gutter 611 and a mounting bracket 612 for the rain gutter 611. The rain gutter 611 is disposed, for example, along the second direction β. The rain gutter 611 is attached to the rail portion 163 of the water-permeable member 16 by a hexagonal bolt 601 using the mounting bracket 612. As shown in FIG. 6, by attaching the rain gutter 611 to the end of the rail portion 163 of the water-permeable member 16 in the first direction α, moisture such as rainwater discharged along the first water-permeable portion 161 of the water-permeable member 16 can flow into the rain gutter 611.

[0032] Fig. 7 is a schematic cross-sectional view showing another example of the water-permeable member 16. Fig. 8 is a schematic cross-sectional view showing the water-permeable member 16 of Fig. 7 together with the solar cell module 11 and the rafter member 12.

[0033] 7, the water-passing member 16 may further have a pair of second water-passing portions 164 extending outward from the respective end portions 162a of the pair of flange portions 162. Each of the pair of second water-passing portions 164 extends in the first direction α and has a concave shape that opens upward. With this structure, for example, moisture such as rainwater that seeps out from between the solar cell module 11 and the flange portions 162 can be discharged via the second water-passing portions 164 of the water-passing member 16.

[0034] 7 and 8, second water passing portion 164 is formed so that its cross section in the second direction β forms an inverted trapezoid. Also, in the example shown in Figures 7 and 8, the depth of second water passing portion 164 is smaller than the depth of first water passing portion 161 in the cross section in the second direction β. However, the shape of second water passing portion 164 is not limited to the example shown in Figures 7 and 8. For example, second water passing portion 164 may be formed so that its cross section forms a V-shape.

[0035] The structure of the carport 100 will be described in detail below with further reference to Figures 9 to 11.

[0036] Figure 9 shows (a) a top view, (b) a side view, and (c) a front view of the carport 100. Figure 10 shows (a) a partial side view of the carport 100, (b) a view of (a) from direction A, and (c) a view of (a) from direction B. Figure 11 is a partial perspective view of the carport 100.

[0037] As shown in Fig. 9(a), in this embodiment, a plurality of solar cell modules 11 arranged side by side in a first direction α and a second direction β constitute a roof member 20. As shown in Fig. 9(a), in this embodiment, the roof member 20 has a total of 30 solar cell modules 11 arranged in two rows along the first direction α and 15 rows along the second direction β.

[0038] Although not shown, each solar cell module 11 may be a double-sided solar cell module in which a plurality of photoelectric conversion cells are arranged in a tile shape, the cells are sandwiched between reinforced glass, and the outer periphery of the glass is surrounded by an aluminum alloy frame. The pair of flanges 162 of the water-passing member 16 may be held between the frame of the solar cell module 11 and the rafter member 12. The frame of the solar cell module 11 and the rafter member 12 may be connected using a fastening member such as a hexagonal bolt.

[0039] As shown in FIG. 9(b), the roof member 20 is inclined with respect to the first direction α. ​​Specifically, in the roof member 20, the multiple solar cell modules 11 are arranged so as to be continuously inclined as a whole with respect to the first direction α. ​​The inclination angle θ of the roof member 20 is, for example, 2° or more and 10° or less. The inclination angle θ may be 3°. When the inclination angle θ is 3°, direct light and scattered light can be efficiently guided to the solar cell module 11 while water such as rainwater can be efficiently discharged by the water-permeable member 16, so that dirt is less likely to accumulate on the surface of the solar cell module 11 due to the flow of rainwater, etc. In the following, as shown in FIGS. 9(a) to (c), the side of the roof member 20 where the distance from the ground G to the roof member 20 is short is called the rear side 201, and the side where the distance from the ground G to the roof member 20 is long is called the front side 202.

[0040] In this embodiment, the carport 100 has a structure in which the rear side 201 of the roof member 20 is cantilevered by multiple supports 15. While the rear side 201 of the roof member 20 is supported by multiple supports 15, no supports 15 are present on the front side 202 of the roof member 20. With this structure, since no supports 15 are present on the front side 202 of the roof member 20, vehicles can be easily loaded and unloaded from the carport 100. This improves the convenience of the carport 100.

[0041] In this embodiment, the support pillars 15 have rear support pillars 151 and front support pillars 152. A total of four rear support pillars 151 are erected vertically to the ground G on the rear side 201 of the roof member 20 so as to form a row along the second direction β. In this embodiment, the ground G is a horizontal surface. A total of four front support pillars 152 are erected vertically to the ground G closer to the front side 202 of the roof member 20 than the rear support pillars 151 so as to form a row along the second direction β.

[0042] As shown in FIG. 9(b), the horizontal length from the end 202a of the front side 202 of the roof member 20 to the end 201a of the rear side 201 in the first direction α is L. 20 When the front support 152 is defined as 1 / 2×L from the end 202a of the front side 202, 20 It is preferable to install it at a position of 2 / 3 x L or more. 20 It is more preferable to install the rear support 151 at the position above. 20 According to such a structure, the front support pillars 152 can be disposed at a position where they do not interfere with driving when parking a vehicle and do not interfere with opening and closing the rear door of a parked vehicle, while reliably supporting the roof member 20. This improves the convenience of the carport 100.

[0043] In this embodiment, a total of four beam members 14 are arranged in four rows along the first direction α. ​​One beam member 14 is supported by two pillars 15 (a rear pillar 151 and a front pillar 152) erected along the first direction α. ​​That is, the four beam members 14 are supported by two pillars 15 (a rear pillar 151 and a front pillar 152) each so as to be parallel to each other in the first direction α.

[0044] In this embodiment, a total of four purlin members 13 are arranged in four rows along the second direction β. The four purlin members 13 are supported by four beam members 14 arranged along the first direction α.

[0045] In this embodiment, the rafter members 12 are arranged along the first direction α at the lower ends 11a, 11b on both sides in the second direction β of each solar cell module 11. In this embodiment, the solar cell modules 11 are arranged in 15 rows along the second direction β, so a total of 30 rafter members 12 are arranged. The 30 rafter members 12 are supported by four purlin members 13 arranged along the second direction β.

[0046] The numbers and arrangements of the solar cell modules 11, rafter members 12, purlin members 13, beam members 14, and supports 15 are not limited to the above-mentioned examples.

[0047] The carport 100 may further include a plurality of diagonal members 17 and a plurality of reinforcing members 18 (shown in FIG. 1). The diagonal members 17 are disposed diagonally within a vertical plane defined by the front support 152 and the beam members 14. The reinforcing members 18 are disposed diagonally within a horizontal plane defined by the purlin members 13 and the beam members 14. By including a plurality of diagonal members 17 and a plurality of reinforcing members 18, the strength of the carport 100 can be improved.

[0048] In this embodiment, the diagonal member 17 includes a rear diagonal member 171 and a front diagonal member 172. As shown in FIG. 10 and FIG. 11, the rear diagonal member 171 may be disposed obliquely so as to connect the connection portion 31 located at a predetermined position in the vertical direction of the front support 152 to the connection portion 32 between the rear support 151 and the beam member 14. The front diagonal member 172 may be disposed obliquely so as to connect the connection portion 31 located at a predetermined position in the vertical direction of the front support 152 to the connection portion 33 located at a predetermined position in the first direction α of the beam member 14. The length of the front diagonal member 172 may be greater than the length of the rear diagonal member 171. With this structure, the strength of the carport 100 in the vertical direction and the front-rear direction can be improved while ensuring the overhang distance from the front support 152 to the end 202a of the front side 202 of the roof member 20.

[0049] 10, the rear support 151, the front support 152, and the beam member 14 may have a structure in which light-gauge steel lip channel steel is arranged back to back. The rear diagonal member 171 and the front diagonal member 172 may have a structure in which light-gauge steel channel steel is arranged back to back.

[0050] The reinforcing members 18 are also called braids. As shown in Fig. 1, the reinforcing members 18 may be arranged in a cross-like manner on the diagonal lines of a rectangle defined by the purlin members 13 and the beam members 14 within the horizontal plane of the rectangle. With such a structure, the horizontal strength of the carport 100 can be improved.

[0051] The carport 100 may further include a concrete foundation 19 formed on the ground G. A plurality of support columns 15 may be erected on the concrete foundation 19. According to such a structure, the support columns 15 are rigidly connected to the concrete foundation 19, so that the verticality of the support columns 15 is restrained and the carport 100 as a whole can be prevented from tipping over.

[0052] 11, a gap (joint) 21 exists along the first direction α between solar cell modules 11 adjacent in the second direction β. The width of the gap 21 in the second direction β is not particularly limited and is, for example, 10 mm or more and 30 mm or less. Water such as rainwater flows from the gap 21 into the first water passage portion 161 of the water passage member 16 and is discharged.

[0053] As shown in Fig. 11, a gap (joint) 22 exists along the second direction β between solar cell modules 11 adjacent in the first direction α. ​​The width of the gap 22 in the first direction α is not particularly limited, and is, for example, 10 mm or more and 30 mm or less. In this embodiment, the gap 22 is closed to prevent moisture such as rainwater from entering. The means for closing the gap 22 is not particularly limited. For example, a fitting member described in Japanese Patent No. 7141782 may be used as a means for closing the gap 22. A commonly used gasket and waterproof seal may be used as a means for closing the gap 22.

[0054] Next, the connections of the various members will be described in more detail with reference to FIGS.

[0055] Although not shown in the figure, the rafter member 12 and the purlin member 13 may be connected using a fastening member such as a hexagonal bolt.

[0056] As shown in FIGS. 10 and 11, the purlin member 13 and the beam member 14 may be connected using a purlin bracket 40.

[0057] 10 and 11, the beam member 14 and the support column 15 may be connected to each other using a fastening member 41. The fastening member 41 is, for example, a hexagonal bolt.

[0058] 10, the beam member 14 and the vertical upper end portion 152b of the front support 152 may be connected at a connection portion 30 located at a predetermined position in the second direction β of the beam member 14. A gusset plate 50 and a fastening member 41 may be used for the connection. In this case, the gusset plate 50 is connected using the fastening member 41 in a state where it is sandwiched between the webs of the beam member 14 having a structure in which light-gauge steel lip channel steel is arranged back-to-back.

[0059] 10, a lower end 171a of a rear diagonal member 171 and a lower end 172a of a front diagonal member 172 may be connected to the front support 152 at a connection portion 31 located at a predetermined position in the vertical direction of the front support 152. A gusset plate 51 and a fastening member 41 may be used for the connection. In this case, the gusset plate 51 is connected using the fastening member 41 while being sandwiched between the webs of the front support 152, which has a structure in which light-gauge steel lip channel steel is arranged back-to-back.

[0060] 10, at the connection portion 32 between the rear support 151 and the beam member 14, the upper end portion 171b of the rear diagonal member 171 may be connected to the rear support 151 and the beam member 14. For the connection, a gusset plate 52 and fastening members 41 may be used. In this case, the gusset plate 52 is connected using the fastening members 41 while being sandwiched between the webs of the rear support 151 and the beam member 14, which are made of back-to-back lip channel steel made of lightweight steel.

[0061] 11 , an upper end 172b of a front diagonal member 172 may be connected to the beam member 14 at a connection portion 33 located at a predetermined position in the first direction α of the beam member 14. A gusset plate 53 and a fastening member 41 may be used for the connection. In this case, the gusset plate 53 is connected using the fastening member 41 in a state where it is sandwiched between the webs of the beam member 14 having a structure in which light-gauge steel lip channel steel is arranged back-to-back.

[0062] Like the rafter members 12, the purlin members 13, beam members 14, and pillars 15 are preferably made of lightweight steel. In this case, the weight of each member can be reduced, and the transportability and workability of each member are improved. In addition, by making the pillars 15 and beam members 14 out of lightweight steel back to back, the gusset plates 51, 52, and 53 can be sandwiched between the webs of the lightweight steel, eliminating the need for welding and improving the manufacturability of each member.

[0063] The purlin member 13, the beam member 14, and the support 15 may be steel sheets that have been subjected to high corrosion-resistant pre-plating. High corrosion-resistant pre-plating has a thinner plating layer than hot-dip galvanizing, but has higher corrosion resistance than hot-dip galvanizing. Therefore, even if a steel sheet that has been subjected to high corrosion-resistant pre-plating in a factory is bent, the plating is less likely to crack or peel off. In addition, when hot-dip galvanizing is performed after bending, the processed part is deformed due to the heat of the plating tank, but a steel sheet that has been subjected to high corrosion-resistant pre-plating does not deform due to its high shape accuracy. Furthermore, since high corrosion-resistant pre-plating does not cause uneven plating or sagging like hot-dip galvanizing, the surface is smooth, improving the commercial value of buildings that place importance on design, such as carports.

[0064] The above-described embodiments are described for the purpose of facilitating understanding of the present invention, and are not described for the purpose of limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design modifications and equivalents that fall within the technical scope of the present invention. [Industrial Applicability]
