Summary of the Invention

Problems to be Solved by the Invention

[0004] As members used for a carport (for example, cross members such as rafter members and roof members), for example, welded H-shaped steel or welded T-shaped steel made of steel with hot-dip galvanized coating on the surface is widely used for corrosion prevention. However, for example, welded H-shaped steel made of steel is manufactured by welding three thick plates so as to have an H-shaped cross section, so it is inferior in light weight and causes a decrease in transportability and constructability. In addition, hot-dip galvanized coating has a problem in terms of corrosion resistance because corrosion progresses due to rainwater, dew condensation, seawater droplets, etc.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a solar carport that achieves weight reduction and has excellent corrosion resistance.

Means for Solving the Problems

[0006] In order to achieve the above object, the present invention provides a solar carport including: a plurality of solar cell modules arranged side by side in a first direction and a second direction orthogonal to the first direction; a plurality of vertical members arranged along the first direction at lower end portions on both sides in the second direction of each of the solar cell modules so as to support the plurality of solar cell modules; and a plurality of water passage members arranged along the first direction between two adjacent vertical members in the second direction. The vertical members are lightweight steel sections made of steel, and the water passage members include a first water passage portion having a concave shape that extends in the first direction and opens upward between two adjacent vertical members in the second direction, and a pair of flange portions extending outward from upper end portions on both sides in the second direction of the first water passage portion. Each of the pair of flange portions is sandwiched between the solar cell module and the vertical member (Invention 1).

[0007] According to such an invention (Invention 1), since the vertical members are lightweight steel sections made of steel, the weight of the vertical members is reduced. As a result, the transportability and constructability of the vertical members are improved. In addition, moisture such as rainwater can be discharged from the carport through the first water passage portion of the water passage member, and the upper surface portion of the vertical member is protected by the flange portion of the water passage member, so that corrosion of the vertical member due to rainwater or the like is suppressed.

[0008] In the above invention (Invention 1), it is preferable that the water passage member is an extruded profile made of aluminum or an aluminum alloy (Invention 2).

[0009] A profile made of aluminum or an aluminum alloy is more corrosion-resistant than a steel profile with hot-dip galvanized coating on its surface. In addition, a profile made of aluminum or an aluminum alloy can be manufactured at a lower cost than, for example, a stainless steel profile. Therefore, according to such an invention (Invention 2), corrosion of the water passage member due to rainwater or the like is suppressed, and the cost of the water passage member can be reduced.

[0010] In the above inventions (Inventions 1 and 2), the water passage member further has a rail portion that extends in the first direction and has a concave shape that opens downward between two of the vertical member portions adjacent to each other in the second direction, and the rail portion may be configured to be able to insert and hold a fastening member from end portions on both sides in the first direction (Invention 3).

[0011] According to such an invention (Invention 3), by using a fastening member, it is possible to attach accessory parts to the rail portion, such as external lighting, a rain gutter arranged along the second direction, and the like.

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

[0013] According to such an invention (Invention 4), moisture such as rainwater that has oozed out from between, for example, a solar cell module and a flange portion can be discharged through the second water passage portion of the water passage member.

Advantages of the Invention

[0014] According to the solar carport according to the present invention, since the vertical member portion is a lightweight steel section made of steel, the weight reduction of the vertical member portion is realized. As a result, the transportability and constructability of the vertical member portion are improved. Further, moisture such as rainwater can be discharged from the carport through the first water passage portion of the water passage member, and the upper surface portion of the vertical member portion is protected by the flange portion of the water passage member, so that corrosion of the vertical member portion by rainwater or the like is suppressed.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, embodiments of the solar carport according to the present invention will be described with reference to the drawings as appropriate. The embodiments described below are for facilitating the understanding of the present invention and do not limit the present invention in any way.

[0017] 〔Solar Carport〕 FIG. 1 is a schematic perspective view of a solar carport 100 (hereinafter simply referred to as "carport 100") according to an embodiment of the present invention as seen from below. FIG. 2 is a schematic perspective view of the carport 100 as seen from above.

[0018] The carport 100 includes a plurality of solar cell modules 11, a plurality of rafter members 12, a plurality of roof members 13, a plurality of beam members 14, and a plurality of columns 15.

[0019] A plurality of solar cell modules 11 are arranged side by side in a first direction α and a second direction β orthogonal to the first direction α. A plurality of purlin members 12 are arranged along the first direction α so as to support the plurality of solar cell modules 11. A plurality of roof members 13 are arranged along the second direction β so as to support the plurality of purlin members 12. A plurality of beam members 14 are arranged along the first direction α so as to support the plurality of roof members 13. A plurality of columns 15 support the plurality of beam members 14 and are erected on the ground G.

[0020] In the present embodiment, the purlin member 12 is a lightweight steel section made of steel. Thereby, the weight reduction of the purlin member 12 is realized. As a result, the transportability and constructability of the purlin member 12 are improved.

[0021] In the present embodiment, the carport 100 further includes a plurality of water passage members 16 arranged along the first direction α between two adjacent purlin members 12 in the second direction β.

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

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

[0024] As shown in FIGS. 3 and 4, the water passage member 16 includes a first water passage 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 the upper end portions 161a on both sides of the first water passage portion 161 in the second direction β. 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 such a structure, moisture such as rainwater can be discharged from the carport 100 through the first water passage portion 161 of the water passage member 16, and the upper surface portion 12a of the rafter member 12 is protected by the flange portion 162 of the water passage member 16, so that corrosion of the rafter member 12 due to rainwater or the like is suppressed.

[0025] As shown in FIG. 4, it is preferable that the length of the flange portion 162 in the second direction β is approximately the same as or greater than the length of the upper surface portion 12a of the rafter member 12 in the second direction β. According to such a structure, corrosion of the rafter member 12 due to rainwater or the like is further suppressed. The length of the flange portion 162 in the second direction β may be the same as or greater than the length of the upper surface portion 12a of the rafter member 12 in the second direction β.

[0026] The water passage member 16 is preferably an extruded profile made of aluminum or an aluminum alloy. For example, the extruded profile is a profile manufactured by the hot extrusion method. According to the hot extrusion method, since it is extruded through a die machined into various shapes, a profile with a complex shape can be manufactured. A profile made of aluminum or an aluminum alloy is more corrosion-resistant than a steel profile with hot-dip galvanized zinc. In addition, a profile made of aluminum or an aluminum alloy can be manufactured at a lower cost than, for example, a steel profile made of stainless steel. Therefore, if the water passage member 16 is an extruded profile made of aluminum or an aluminum alloy, corrosion of the water passage member 16 due to rainwater or the like is suppressed. As a result, corrosion of the rafter member 12 is further suppressed. In addition, the cost of the water passage member 16 can be reduced.

[0027] As shown in FIGS. 3 and 4, the water passage member 16 may further have a rail portion 163 that extends in the first direction α between two vertical member 12 adjacent in the second direction β and has a concave shape that opens downward. The rail portion 163 is First direction α preferably configured to be able to insert and hold the fastening member 60 from both end portions on both sides thereof. According to such a structure, the fastening member 60 can be used to attach an accessory 61, such as external lighting, a rain gutter arranged along the second direction, etc., to the rail portion 163.

[0028] As shown in FIGS. 3 and 4, in the cross-section in the second direction β, the first water passage portion 161 and the rail portion 163 have concave shapes facing each other in the vertical direction.

[0029] As shown in FIG. 3, the rail portion 163 may have a rail groove 163a that extends in the first direction α such that the fastening member 60 can be inserted and held. The rail groove 163a may be formed by bending the 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 passage member 16 and the accessory 61. The fastening member 60 is, for example, a bolt having a head and a shaft portion, and typically, a hexagon bolt 601. In the example shown in FIGS. 3 and 4, the rail portion 163 has a rail groove 163a that extends in the first direction α such that the shaft portion 601b of the hexagon bolt 601 can be inserted and the head 601a of the hexagon bolt 601 can be held. The head 601a of the hexagon bolt 601 is located inside the rail groove 163a, and the shaft portion 601b of the hexagon bolt 601 is located outside the rail groove 163a.

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

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

[0033] As shown in FIG. 7, the water passage member 16 may further have a pair of second water passage portions 164 extending outward from the respective end portions 162a of the pair of flange portions 162. Each of the pair of second water passage portions 164 has a concave shape extending in the first direction α and opening upward. According to such a structure, moisture such as rainwater oozing out from between the solar cell module 11 and the flange portion 162 can be discharged through the second water passage portion 164 of the water passage member 16.

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

[0035] Hereinafter, with further reference to FIGS. 9 to 11, the structure of the carport 100 will be described in detail.

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

[0037] As shown in FIG. 9(a), in the present embodiment, a plurality of solar cell modules 11 arranged side by side in the first direction α and the second direction β constitute the roof member 20. As shown in FIG. 9(a), in the present embodiment, the roof member 20 has a total of 30 solar cell modules 11 arranged in 2 rows along the first direction α and 15 rows along the second direction β.

[0038] Although illustration is omitted, each solar cell module 11 may be a double-sided power generation type solar cell module in which a plurality of cells for photoelectric conversion are arranged in a tile shape, these cells are sandwiched between tempered glasses, and the outer periphery of the glass is surrounded by a frame made of an aluminum alloy. The pair of flange portions 162 of the water passage member 16 may be sandwiched 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 plurality of 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, and moisture such as rainwater can be efficiently discharged by the water passage member 16. Therefore, dirt is less likely to accumulate on the surface of the solar cell module 11 due to the flow of rainwater or the like. Hereinafter, as shown in FIGS. 9(a) to 9(c), in the roof member 20, the side where the distance from the ground G to the roof member 20 is small is called the rear side 201, and the side where the distance from the ground G to the roof member 20 is large 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 columns along the first direction α. One beam member 14 is supported by two columns 15 (a rear column 151 and a front column 152) erected along the first direction α. That is, the four beam members 14 are respectively supported by two columns 15 (a rear column 151 and a front column 152) so as to be parallel to each other in the first direction α.

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

[0045] In this embodiment, the purlin members 12 are arranged along the first direction α at the lower end portions 11a and 11b on both sides in the second direction β of the respective solar cell modules 11. In this embodiment, since the solar cell modules 11 are arranged in 15 columns along the second direction β, a total of 30 purlin members 12 are arranged. The 30 purlin members 12 are supported by the four roof members 13 arranged along the second direction β.

[0046] The number and arrangement of the solar cell modules 11, purlin members 12, roof members 13, beam members 14, and columns 15 are not limited to the above-described 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 arranged in a diagonal direction within the vertical plane defined by the front column 152 and the beam member 14. The reinforcing members 18 are arranged in a diagonal direction within the horizontal plane defined by the roof member 13 and the beam member 14. By providing the plurality of diagonal members 17 and the plurality of reinforcing members 18, the strength of the carport 100 can be improved.

[0048] In this embodiment, the diagonal member 17 has a rear diagonal member 171 and a front diagonal member 172. As shown in FIGS. 10 and 11, the rear diagonal member 171 may be obliquely arranged so as to connect a connection portion 31 located at a predetermined position in the vertical direction of the front column 152 and a connection portion 32 between the rear column 151 and the beam member 14. The front diagonal member 172 may be obliquely arranged so as to connect a connection portion 31 located at a predetermined position in the vertical direction of the front column 152 and a 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. According to such a structure, while securing the overhang distance from the front column 152 to the end portion 202a of the front side 202 of the roof member 20, the strength in the vertical direction and the front-rear direction of the carport 100 can be improved.

[0049] As shown in FIG. 10, the rear column 151, the front column 152, and the beam member 14 may have a structure in which lightweight steel lip channel steels are placed back to back. The rear diagonal member 171 and the front diagonal member 172 may have a structure in which lightweight steel channel steels are placed back to back.

[0050] The reinforcing member 18 is also called a brace. As shown in FIG. 1, the reinforcing member 18 may be arranged like a cross brace on the diagonal of the quadrilateral in the horizontal plane defined by the roof member 13 and the beam member 14. According to such a structure, the strength in the horizontal direction 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 columns 15 may be erected on the concrete foundation 19. According to such a structure, since the columns 15 are rigidly connected to the concrete foundation 19, the verticality of the columns 15 is restricted and the overturning of the carport 100 as a whole can be prevented.

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

[0053] As shown in Fig. 11, there is a gap (joint) 22 along the second direction β between the solar cell modules 11 adjacent to the first direction α. The width of the gap 22 in the first direction α is not particularly limited, for example, it is 10 mm or more and 30 mm or less. In this embodiment, the gap 22 is blocked so that moisture such as rainwater does not penetrate. The means for blocking the gap 22 is not particularly limited. For example, as a means for blocking the gap 22, the fitting member described in Japanese Patent No. 7141782 may be used. As a means for blocking the gap 22, generally used gaskets and waterproof seals may also be used.

[0054] Next, with reference to Figs. 10 and 11, the connection portions of each member and the like will be described in more detail.

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

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

[0057] As shown in Figs. 10 and 11, the beam member 14 and the column 15 may be connected using a fastening member 41. The fastening member 41 is, for example, a hexagonal bolt.

[0058] As shown in FIG. 10, at the connection portion 30 located at a predetermined position in the second direction β of the beam member 14, the beam member 14 and the upper end portion 152b in the vertical direction of the front column 152 may be connected. For the connection, a gusset plate 50 and a fastening member 41 may be used. In this case, the gusset plate 50 is connected using the fastening member 41 while being sandwiched between the webs of the beam member 14 having a structure in which lip channel steels of lightweight steel are placed back to back.

[0059] As shown in FIG. 10, at the connection portion 31 located at a predetermined position in the vertical direction of the front column 152, the lower end portion 171a of the rear diagonal member 171 and the lower end portion 172a of the front diagonal member 172 may be connected to the front column 152. For the connection, a gusset plate 51 and a fastening member 41 may be used. In this case, the gusset plate 51 is connected using the fastening member 41 while being sandwiched between the webs of the front column 152 having a structure in which lip channel steels of lightweight steel are placed back to back.

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

[0061] As shown in FIG. 11, at the connection portion 33 located at a predetermined position in the first direction α of the beam member 14, the upper end portion 172b of the front diagonal member 172 may be connected to the beam member 14. For the connection, a gusset plate 53 and a fastening member 41 may be used. In this case, the gusset plate 53 is connected using the fastening member 41 while being sandwiched between the webs of the beam member 14 having a structure in which lip channel steels of lightweight steel are placed back to back.

[0062] Similar to the purlin member 12, the roof member 13, the beam member 14, and the column 15 are preferably made of lightweight steel sections. In this case, the weight of each member can be reduced, and the transportability and constructability of each member are improved. Further, by adopting a structure in which the column 15 and the beam member 14 are back-to-back lightweight steel sections, the gusset plates 51, 52, and 53 can be sandwiched between the webs of the lightweight steel sections, so that welding is not required and the manufacturability of each member is improved.

[0063] The roof member 13, the beam member 14, and the column 15 may be steel plates with high corrosion-resistant pre-plating. The 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 when a steel plate that has been subjected to high corrosion-resistant pre-plating treatment at a factory is bent, there is an advantage that the plating is less likely to crack or peel. Further, when hot-dip galvanizing is performed after bending, the processed portion is deformed back by the heat of the plating bath, but a steel plate with high corrosion-resistant pre-plating does not undergo back deformation and has excellent shape accuracy. Furthermore, since the high corrosion-resistant pre-plating does not cause plating unevenness or sagging like hot-dip galvanizing, the surface becomes smooth, improving the commercial value in buildings that emphasize design, such as carports.

[0064] The embodiments described above are described to facilitate the understanding of the present invention and are not described to limit the present invention. Therefore, each element disclosed in the above embodiments is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

Industrial Applicability

[0065] The solar carport according to the present invention is useful in the technical field of solar cell modules and the technical field of carports because it realizes weight reduction and has excellent corrosion resistance.
