Description

Technical Field

[0001] This invention relates to a solar-powered carport. Background Technology

[0002] In solar power systems using solar cell modules, it is necessary to make full use of sunlight in order to increase power generation. Therefore, in the prior art, solar cell modules are installed on the roofs of residences and building rooftops where there is good sunlight. In recent years, solar carports using solar cell modules to construct roof components have been proposed (e.g., Patent Documents 1 and 2).

[0006] Patent Document 2: Japanese Patent Application Publication No. 2016-141971 Summary of the Invention

[0007] Technical issues

[0008] Components used in carports (e.g., rafters, purlins, and other frame materials) often employ welded H-beams and T-beams made of steel with a hot-dip galvanized surface for corrosion protection. However, welded H-beams, for example, are manufactured by joining three thick plates together by welding to achieve an H-shaped cross-section. This results in poor lightweight properties, reducing transportability and ease of construction. Furthermore, hot-dip galvanizing presents challenges in terms of corrosion resistance, as rainwater, dew, and seawater splashes exacerbate corrosion.

[0009] In view of the above-mentioned actual situation, the present invention is proposed, and its purpose is to provide a solar carport that can achieve lightweight and excellent corrosion resistance.

[0010] Problem-solving methods

[0011] To achieve the above objectives, the present invention provides a solar carport, comprising: a plurality of solar cell modules arranged side-by-side along a first direction and a second direction orthogonal to the first direction; a plurality of rafter components arranged along the first direction on both sides of the bottom edge of each of the solar cell modules in the second direction to support the plurality of solar cell modules; and a plurality of water guiding components arranged along the first direction between two adjacent rafter components in the second direction, wherein the rafter components are made of lightweight steel, and the water guiding components have a first water guiding portion and a pair of flange portions, wherein the first water guiding portion has a concave shape extending along the first direction between two adjacent rafter components in the second direction and opening upward; and the flange portions extend outward from the upper ends of both sides of the first water guiding portion in the second direction, and the flange portions are respectively clamped by the solar cell modules and the rafter components (Invention 1).

[0012] According to the present invention (Invention 1), the rafter component is made of lightweight steel, thereby achieving weight reduction of the rafter component. This improves the transportability and workability of the rafter component. Furthermore, rainwater and other moisture can be drained from the roof through the first water-guiding part of the water-guiding component, and the upper surface of the rafter component is protected by the flange of the water-guiding component, thereby inhibiting corrosion of the rafter component by rainwater and other substances.

[0013] In the above invention (Invention 1), preferably, the water guiding component is an aluminum or aluminum alloy extruded profile (Invention 2).

[0014] Aluminum or aluminum alloy profiles exhibit superior corrosion resistance compared to steel profiles with hot-dip galvanized surfaces. Furthermore, aluminum or aluminum alloy profiles can be manufactured at a lower cost than stainless steel profiles. Therefore, according to the present invention (Invention 2), corrosion of the water-guiding components by rainwater and other sources can be suppressed, while simultaneously reducing the cost of the water-guiding components.

[0015] In the above inventions (Inventions 1 and 2), the water guiding component also has a track portion, which has a concave shape extending downward between two adjacent rafter components in the second direction and opening in the first direction. The track portion is configured to be able to be inserted into and support fastening components from both ends in the first direction (Invention 3).

[0016] According to the present invention (invention 3), fastening components can be used to install auxiliary components on the track section, such as external lighting, rainwater troughs arranged in the second direction, etc.

[0017] In the above inventions (Inventions 1-3), the water guiding component further has a pair of second water guiding portions, which extend outward from the respective ends of the pair of flange portions, and the pair of second water guiding portions each have a concave shape that extends along the first direction and opens upward (Invention 4).

[0018] According to the present invention (invention 4), water such as rainwater that seeps between the solar cell assembly and the flange portion can be discharged through the second water-guiding part of the water-guiding component.

[0019] The effects of the invention

[0020] According to the solar-powered carport of the present invention, the rafter components are made of lightweight steel, thereby achieving weight reduction. As a result, the transportability and construction feasibility of the rafter components are optimized. Furthermore, rainwater and other moisture can be drained from the carport through the first water-guiding portion of the water-guiding component, and the upper surface of the rafter components is protected by the flange portion of the water-guiding component, thereby inhibiting corrosion of the rafter components by rainwater and other substances.

[0031] Figure 11 yes Figure 1 A partial 3D view of the solar-powered carport. Detailed Implementation

[0032] The embodiments of the solar-powered carport according to the present invention will now be described with reference to the accompanying drawings. The embodiments described below are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] Solar carport

[0034] Figure 1 This is a schematic perspective view of a solar-powered carport 100 (hereinafter referred to as "carport 100") according to an embodiment of the present invention, viewed from below. Figure 2 This is a schematic 3D view of the carport 100 as viewed from above.

[0035] The carport 100 includes multiple solar cell modules 11, multiple rafter components 12, multiple purlin components 13, multiple beam components 14, and multiple support columns 15.

[0036] Multiple solar cell modules 11 are arranged side-by-side along a first direction α and a second direction β orthogonal to the first direction α. ​​Multiple rafter members 12 are arranged along the first direction α to support the multiple solar cell modules 11. Multiple purlin members 13 are arranged along the second direction β to support the multiple rafter members 12. Multiple beam members 14 are arranged along the first direction α to support the multiple purlin members 13. Multiple support columns 15 support the multiple beam members 14 and are vertically arranged on the foundation G.

[0037] In this embodiment, the rafter component 12 is made of lightweight steel. This achieves weight reduction in the rafter component 12. Consequently, the transport and construction performance of the rafter component 12 is improved.

[0038] In this embodiment, the carport 100 also includes a plurality of water guiding components 16, which are arranged along a first direction α between two adjacent rafter components 12 along a second direction β.

[0039] Figure 3 An example of a water guiding component 16 is shown. Figure 3 This is a schematic cross-sectional view of the water guiding component 16 in the second direction β. Figure 4 It is Figure 3 A schematic cross-sectional view of the water guiding component 16 together with the solar cell assembly 11 and the rafter component 12.

[0040] like Figure 4As shown, multiple rafter components 12 are disposed along a first direction α (perpendicular to the plane of the paper) on the bottom edges 11a, 11b on both sides of a second direction β along each solar cell module 11 to support the multiple solar cell modules 11.

[0041] like Figure 3 and Figure 4 As shown, the water guiding component 16 has a first water guiding portion 161 and a pair of flange portions 162, wherein the first water guiding portion 161 has a concave structure extending along the first direction α and opening upward between two adjacent rafter components 12 in the second direction β; the pair of flange portions 162 extend outward from the upper ends 161a on both sides of the first water guiding portion 161 in the second direction β. Figure 4 As shown, a pair of flanges 162 are respectively held by the solar cell assembly 11 and the rafter component 12. With this structure, rainwater and other moisture can be drained from the carport 100 through the first water guide 161 of the water guide component 16, and the flanges 162 of the water guide component 16 protect the upper surface 12a of the rafter component 12, thereby inhibiting the corrosion of the rafter component 12 by rainwater and the like.

[0042] like Figure 4 As shown, preferably, the length of the flange portion 162 in the second direction β is equal to or longer than the length of the upper surface 12a of the rafter component 12 in the second direction β. This structure further suppresses corrosion of the rafter component 12 by rainwater and other contaminants. The length of the flange portion 162 in the second direction β can be the same as or longer than the length of the upper surface 12a of the rafter component 12 in the second direction β.

[0043] Preferably, the water-guiding component 16 is an extruded profile made of aluminum or aluminum alloy. For example, the extruded profile is manufactured by hot extrusion. According to the hot extrusion method, it is extruded by a die that has been machined into various shapes, thus enabling the manufacture of profiles with complex shapes. The corrosion resistance of aluminum or aluminum alloy profiles is superior to that of steel profiles that have undergone hot-dip galvanizing. In addition, aluminum or aluminum alloy profiles can be manufactured, for example, at a lower cost than stainless steel profiles. Therefore, when the water-guiding component 16 is an extruded profile made of aluminum or aluminum alloy, corrosion of the water-guiding component 16 by rainwater and the like can be suppressed. This further suppresses corrosion of the rafter component 12. In addition, the manufacturing cost of the water-guiding component 16 can be reduced.

[0044] like Figure 3 and Figure 4As shown, the water guiding component 16 may also have a track portion 163, which has a concave shape extending along the first direction α and opening downward between two adjacent rafter components 12 in the second direction β. Preferably, the track portion 163 is configured to be able to be inserted into and support the fastening component 60 from both ends in the second direction β. According to this structure, auxiliary components 61, such as external lighting, rainwater gutters arranged along the second direction, etc., can be mounted on the track portion 163 using the fastening component 60.

[0045] like Figure 3 and Figure 4 As shown, in the cross section of the second direction β, the first water guide portion 161 and the track portion 163 have concave shapes that are opposite each other in the vertical direction.

[0046] like Figure 3 As shown, the track section 163 may also be provided with a track groove 163a extending along the first direction α, so that the fastening member 60 can be inserted and supported therein. The track groove 163a may also be formed by bending the bottom edges 163b on both sides of the track section 163 in the second direction β inward.

[0047] The fastening component 60 is not particularly limited, as long as it can connect the track portion 163 of the water guiding component 16 and the auxiliary component 61. The fastening component 60 is, for example, a bolt with a head and a threaded rod, typically a hex bolt 601. Figure 3 and Figure 4 In the example shown, the track portion 163 has a track groove 163a extending along a first direction α, such that the thread 601b of the hex bolt 601 can both pass through the track groove 163a and have its head 601a supported in the track groove 163a. ​​The head 601a of the hex bolt 601 is located inside the track groove 163a, while the thread 601b of the hex bolt 601 is located outside the track groove 163a.

[0048] Figure 5 This indicates that the auxiliary component 61 is installed using the fastening component 60. Figure 3 A schematic diagram of an embodiment of the track portion 163 of the water guiding component 16 shown. Figure 6 yes Figure 5 Side view. In Figure 5 and Figure 6 In the illustrated embodiment, the auxiliary component 61 includes a rainwater trough 611 and a mounting bracket 612 for the rainwater trough 611. The rainwater trough 611 is configured, for example, along a second direction β. The rainwater trough 611 is mounted on the track portion 163 of the water guiding component 16 via the mounting bracket 612 and hexagonal bolts 601. Figure 6As shown, by installing a rainwater trough 611 at the end of the track portion 163 of the water guiding component 16 in the first direction α, rainwater and other water discharged along the first water guiding portion 161 of the water guiding component 16 can flow into the rainwater trough 611.

[0049] Figure 7 This is a schematic cross-sectional view showing another embodiment of the water guiding component 16. Figure 8 It is Figure 7 A schematic cross-sectional view of the water guiding component 16 together with the solar cell assembly 11 and the rafter component 12.

[0050] like Figure 7 As shown, the water guiding component 16 may also have a pair of second water guiding portions 164, which extend outward from the respective end portions 162a of a pair of flange portions 162. Each of the pair of second water guiding portions 164 has a concave structure extending along a first direction α and opening upward. According to this structure, moisture, such as rainwater, that seeps between the solar cell assembly 11 and the flange portion 162 can be drained through the second water guiding portions 164 of the water guiding component 16.

[0051] exist Figure 7 and Figure 8 In the illustrated embodiment, the second water guide portion 164 may also be formed as an inverted trapezoidal cross-section in the cross-section of the second direction β. Additionally, in Figure 7 and Figure 8 In the illustrated embodiment, in the cross-section along the second direction β, the depth of the second water guide portion 164 is less than the depth of the first water guide portion 161. However, the shape of the second water guide portion 164 is not limited to... Figure 7 and Figure 8 The example shown. For instance, the second water guide section 164 can also be formed as a structure with a V-shaped cross-section.

[0052] Below, refer to Figures 9 to 11 The structure of the carport 100 will be explained in more detail.

[0053] Figure 9 Part (a) is a top view of the carport 100, part (b) is a side view, and part (c) is a front view. Figure 10 Part (a) is a partial side view of the carport 100, part (b) is a view of part (a) from direction A, and part (c) is a view of part (a) from direction B. Figure 11 This is a partial 3D view of the carport 100.

[0054] like Figure 9 As shown in section (a), in this embodiment, a plurality of solar cell modules 11 arranged side by side along the first direction α and the second direction β constitute the canopy component 20. Figure 9As shown in part (a), in this embodiment, the canopy components 20 are arranged in two rows along the first direction α and in 15 rows along the second direction β, having a total of 30 solar cell modules 11.

[0055] Although not explicitly shown in the diagram, each solar cell module 11 can be a bifacial solar cell module, in which multiple cells performing photoelectric conversion are arranged in a flat manner, held in place by reinforced glass, and surrounded by an aluminum alloy frame. The pair of flanges 162 of the water-guiding component 16 can also be held by the aforementioned frame and rafter component 12 of the solar cell module 11. The aforementioned frame and rafter component 12 of the solar cell module 11 can also be connected using fasteners such as hexagonal bolts.

[0056] like Figure 9 As shown in section (b), the canopy component 20 is inclined relative to the first direction α. ​​Specifically, on the canopy component 20, a plurality of solar cell modules 11 are arranged in a manner that is continuously inclined relative to the first direction α. ​​The inclination angle θ of the canopy component 20 is, for example, greater than 2° and less than 10°. The inclination angle θ can be 3°. When the inclination angle θ is 3°, direct and diffused light can be effectively guided to the solar cell modules 11, while rainwater and other moisture can be more effectively discharged through the water guiding component 16. Therefore, dirt will not accumulate on the surface of the solar cell modules 11 due to the flow of rainwater, etc. Figure 9 As shown in parts (a) to (c), the side of the canopy component 20 with the smaller distance from the foundation G to the canopy component 20 is referred to as the rear side 201, and the side with the larger distance from the foundation G to the canopy component 20 is referred to as the front side 202.

[0057] In this embodiment, the carport 100 has a structure in which the rear side 201 of the canopy component 20 is cantilevered by a plurality of pillars 15. The rear side 201 of the canopy component 20 is supported by the plurality of pillars 15, while the front side 202 of the canopy component 20 has no pillars 15. With this structural design, since there are no pillars 15 on the front side 202 of the canopy component 20, vehicles can easily enter and exit the carport 100. This improves the ease of use of the carport 100.

[0058] In this embodiment, the support column 15 has a rear support column 151 and a front support column 152. The rear support columns 151 are arranged in a single row along the second direction β at the rear side 201 of the ceiling component 20, with a total of four columns vertically erected on the foundation G. Furthermore, in this embodiment, the foundation G is a horizontal plane. The front support columns 152 are located closer to the front side 202 of the ceiling component 20 than the rear support columns 151, and are arranged in a single row along the second direction β, with a total of four columns vertically erected on the foundation G.

[0059] like Figure 9As shown in part (b), when the length of the canopy component 20 in the horizontal direction from its front end 202a to its rear end 201a in the first direction α is defined as L 20 In this case, the front support 152 is preferably positioned at a distance of 1 / 2 × L from the end 202a of the front side 202. 20 The above position is more preferably set at 2 / 3×L 20 The above positions. The rear support 151 is preferably located at a distance L from the end 202a of the front side 202. 20 The structure reliably supports the canopy component 20 while preventing the front pillar 152 from obstructing driving operations when the vehicle is parked. Furthermore, the front pillar 152 can be positioned so as not to interfere with the opening and closing of the rear door of the parked vehicle. Therefore, the usability of the carport 100 is improved.

[0060] In this embodiment, a total of four beam members 14 are arranged in four rows along the first direction α. ​​Each beam member 14 is supported by two pillars 15 (rear pillar 151 and front pillar 152) erected along the first direction α. ​​That is, the four beam members 14 are parallel to each other in the first direction α and are supported by two pillars 15 (rear pillar 151 and front pillar 152) respectively.

[0061] 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.

[0062] In this embodiment, rafter members 12 are arranged along the first direction α at the bottom edges 11a and 11b on both sides of the second direction β of each solar cell module 11. In this embodiment, the solar cell modules 11 are arranged in 15 columns along the second direction β, therefore, a total of 30 rafter members 12 are arranged. The 30 rafter members 12 are supported by 4 purlin members 13 arranged along the second direction β.

[0063] The number and arrangement of solar cell modules 11, rafter components 12, purlin components 13, beam components 14 and support columns 15 are not limited to the examples described above.

[0064] The carport 100 may also include multiple diagonal bracing members 17 and multiple reinforcing components 18. Figure 1 (See diagram). The diagonal bracing member 17 is arranged obliquely in the vertical plane defined by the front support 152 and the beam member 14. The reinforcing member 18 is arranged obliquely in the horizontal plane defined by the purlin member 13 and the beam member 14. By providing multiple diagonal bracing members 17 and multiple reinforcing members 18, the structural strength of the carport 100 can be improved.

[0065] In this embodiment, the diagonal brace 17 has a rear diagonal brace 171 and a front diagonal brace 172. For example... Figure 10 and Figure 11 As shown, the rear diagonal brace member 171 can be obliquely configured to connect the connecting portion 31 of the front support column 152 at a specific position in the vertical direction and the connecting portion 32 of the rear support column 151 and the beam member 14. The front diagonal brace member 172 can be obliquely configured to connect the connecting portion 31 of the front support column 152 at a specific position in the vertical direction and the connecting portion 33 of the beam member 14 at a specific position in the first direction α. ​​The length of the front diagonal brace member 172 can be greater than the length of the rear diagonal brace member 171. With this structure, the cantilever distance from the front support column 152 to the end 202a of the front side 202 of the canopy member 20 can be ensured, while the strength of the canopy 100 in both the vertical and longitudinal directions can be improved.

[0066] like Figure 10 As shown, the rear support 151, the front support 152, and the beam component 14 can be constructed using a structure of lightweight steel with rolled-edge channel steel arranged back-to-back. The rear diagonal brace 171 and the front diagonal brace 172 can also be constructed using a structure of lightweight steel with channel steel arranged back-to-back.

[0067] The reinforcing component 18 is also called a diagonal brace. For example... Figure 1 As shown, the reinforcing member 18 is arranged in a cross-bracing manner along the diagonal of the quadrilateral within the horizontal plane defined by the purlin member 13 and the beam member 14. This structure improves the horizontal strength of the carport 100.

[0068] The carport 100 may also include a concrete foundation 19 formed on the foundation G. Multiple supports 15 may be erected in the concrete foundation 19. With this structure, since the supports 15 are rigidly connected to the concrete foundation 19, the verticality of the supports 15 can be constrained, and the carport 100 as a whole can be prevented from tilting.

[0069] like Figure 11 As shown, a gap (seam) 21 exists between adjacent solar cell modules 11 in the second direction β, along the first direction α. ​​The width of the gap 21 in the second direction β is not particularly limited, for example, it is more than 10 mm and less than 30 mm. Rainwater and other moisture flow from the gap 21 into the first water guiding portion 161 of the water guiding member 16 and are discharged therefrom.

[0070] like Figure 11As shown, a gap (seam) 22 exists between adjacent solar cell modules 11 in the first direction α, along the second direction β. 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 sealed to prevent the intrusion of moisture such as rainwater. The method of sealing the gap 22 is not particularly limited. For example, the fitting component described in Japanese Patent No. 7141782 can be used as a method of sealing the gap 22. Conventionally used gaskets and waterproof sealants can also be used as means of sealing the gap 22.

[0071] Next, refer to Figure 10 and Figure 11 The connections between the various components are described in more detail.

[0072] Although not shown in the diagram, the rafter assembly 12 and the purlin assembly 13 can also be connected using fasteners such as hexagonal bolts.

[0073] like Figure 10 and Figure 11 As shown, the purlin component 13 and the beam component 14 can also be connected using the purlin bracket 40.

[0074] like Figure 10 and Figure 11 As shown, beam component 14 and support column 15 can be connected using fastener 41. Fastener 41 can be, for example, a hexagonal bolt.

[0075] like Figure 10 As shown, the beam member 14 and the upper vertical end 152b of the front support column 152 can also be connected at the connection portion 30 located at a predetermined position in the second direction β at the beam member 14. This connection can use a gusset plate 50 and a fastening member 41. In this case, the gusset plate 50 is sandwiched between the webs of the beam member 14 and connected by the fastening member 41, wherein the beam member 14 adopts a structure in which rolled channel steel made of lightweight steel is arranged back to back.

[0076] like Figure 10 As shown, at the connection 31 located at a predetermined position in the vertical direction of the front strut 152, the lower end 171a of the rear diagonal brace 171 and the lower end 172a of the front diagonal brace 172 can be connected to the front strut 152. A node plate 51 and a fastening member 41 can be used for the connection. In this case, the node plate 51 is sandwiched between the webs of the front strut 152 and connected by the fastening member 41, wherein the front strut 152 adopts a structure made of lightweight steel with rolled-edge channel steel arranged back-to-back.

[0077] like Figure 10As shown, at the connection 32 between the rear support column 151 and the beam member 14, the upper end 171b of the rear diagonal brace member 171 can be connected to both the rear support column 151 and the beam member 14. A gusset plate 52 and a fastening member 41 can be used for this connection. In this case, the gusset plate 52 is sandwiched between the webs of the rear support column 151 and the beam member 14 and connected by the fastening member 41. The rear support column 151 and the beam member 14 are constructed using lightweight steel rolled channel steel arranged back-to-back.

[0078] like Figure 11 As shown, at the connection portion 33 located at a predetermined position in the first direction α of the beam member 14, the upper end 172b of the front diagonal brace member 172 can be connected to the beam member 14. A node plate 53 and a fastening member 41 can be used for connection. In this case, the node plate 53 is sandwiched between the webs of the beam member 14 and connected by the fastening member 41, wherein the beam member 14 adopts a structure composed of back-to-back arranged rolled channel steel made of lightweight steel.

[0079] Similar to rafter component 12, purlin component 13, beam component 14, and support column 15 are preferably made of lightweight steel. In this case, both the weight reduction of each component and the transportation and construction performance of each component can be achieved. In addition, by using a structure in which the support column 15 and beam component 14 are arranged back-to-back with lightweight steel, the node plates 51, 52, and 53 can be clamped between the webs of the lightweight steel, thereby eliminating the need for welding and improving the manufacturing efficiency of each component.

[0080] Purlin components 13, beam components 14, and supports 15 can also be made of steel sheets pre-treated with high corrosion resistance. While the pre-coated layer is thinner than that of hot-dip galvanized steel, it offers significantly higher corrosion resistance. Therefore, even when bending the pre-coated steel sheet in the factory, the coating is less prone to cracking or peeling. Furthermore, while hot-dip galvanizing after bending can cause springback deformation at the workpiece, pre-coated steel sheets maintain excellent shape accuracy without springback. Moreover, unlike hot-dip galvanizing, the pre-coated layer does not exhibit uneven coating or runs, resulting in a smooth surface and enhancing the aesthetic value of buildings such as carports.

[0081] The embodiments described above are intended to facilitate understanding of the present invention and are not intended to limit the invention. Therefore, the structural elements disclosed in the above embodiments are intended to cover all design changes and equivalent substitutions that fall within the technical scope of the present invention.
