DETAILED DESCRIPTION OF THE INVENTION

[0017] The first girder member 13 is fixed to the first pillar member 11. The first girder member 13 may be fixed to the first pillar member 11 by any method. For example, the first girder member 13 may be fixed by fastening with bolts and nuts, by welding, or by a joint. The first girder member 13 may sandwich, for example, a height-adjusting spacer together with the first pillar member 11. In a configuration in which the solar-cell carport 10 includes multiple first pillar members 11, the first girder member 13 may be provided so as to span at least two adjacent first pillar members 11.

[0018] The second girder member 14 extends in a second direction. The second girder member 14 may be made of metal. The second girder member 14 may be an H-shaped steel beam having an H-shaped cross section perpendicular to the longitudinal direction. The second girder member 14 may be a series of steel members, and may be formed by joining multiple steel members by any method such as welding or joints.

[0019] The second girder member 14 is fixed to the second pillar member 12. The second girder member 14 may be fixed to the second pillar member 12 by any method. For example, the second girder member 14 may be fixed by fastening with bolts and nuts, by welding, or by a joint. The second girder member 14 may sandwich, for example, a height-adjusting spacer together with the second pillar member 12. In a configuration in which the solar-cell carport 10 includes multiple second pillar members 12, the second girder member 14 may be provided so as to span at least two adjacent second pillar members 12.

[0020] As shown in Fig. 1, the rafter member 15 may be a column-shaped member having a longitudinal direction. The rafter member 15 may be made of metal. The rafter member 15 may be an H-shaped steel beam having an H-shaped cross section perpendicular to the longitudinal direction. The rafter member 15 may be a series of steel members, and may be formed by joining multiple steel members by any method such as welding or joints.

[0021] As shown in FIG. 3 , the rafter member 15 is arranged perpendicular to the first and second girder members 13 and 14 between both ends of the rafter member 15 in the longitudinal direction. The rafter member 15 may be fixed to the first and second girder members 13 and 14 by any method. For example, the rafter member 15 may be fixed by fastening with bolts and nuts, by welding, or by joints. The rafter member 15 may sandwich, for example, a height-adjusting spacer between the rafter member 15 and the first girder member 13. The rafter member 15 may sandwich, for example, a height-adjusting spacer between the rafter member 15 and the second girder member 14. In a configuration in which the solar-cell carport 10 includes multiple rafter members 15, the multiple rafter members 15 may be aligned along the second direction.

[0022] With respect to the rafter member 15, the first girder member 13 and the second girder member 14 satisfy the following formulas (1) to (3). With respect to the rafter member 15, the first girder member 13 and the second girder member 14 may further satisfy the following formula (4). L / 4 <L1 (1) 0 <L3 (2) L1 <L2 (3) L3 <L1 (4)

[0023] As shown in FIG. 1, in formula (1), L is the total length of the rafter member 15 in the longitudinal direction. Furthermore, in formulas (1), (3), and (4), L1 is the length of the portion of the rafter member 15 from the first end e1 in the longitudinal direction to the first girder member 13. The portion from the first end e1 to the first girder member 13 may refer to the portion of the rafter member 15 from the position of the first end e1 in the longitudinal direction to the center position of the width of the first girder member 13. The first end e1 is the end of the rafter member 15 located closer to the first girder member 13 than the second girder member 14 in the longitudinal direction. In other words, the first girder member 13 is located closer to the first end e1 than the second girder member 14. The first end e1 may be located higher relative to the horizontal plane than the second end e2, which is the other end in the longitudinal direction. In equation (3), L2 is the longitudinal length of the portion of the rafter member 15 sandwiched between the first girder member 13 and the second girder member 14. The portion of the rafter member 15 sandwiched between the first girder member 13 and the second girder member 14 may refer to the portion of the rafter member 15 from the center of the width of the first girder member 13 to the center of the width of the second girder member 14 in the longitudinal direction. In equation (2), L3 is the longitudinal length of the portion of the rafter member 15 from the second end e2 to the second girder member 14 in the longitudinal direction. The portion of the rafter member 15 from the second end e2 to the second girder member 14 may refer to the portion of the rafter member 15 from the second end e2 to the center of the width of the second girder member 14 in the longitudinal direction. As described above, the second end e2 is the end of the rafter member 15 opposite the first end e1 in the longitudinal direction. Therefore, the second end e2 is located closer to the second beam member 14 than to the first beam member 13 in the longitudinal direction of the rafter member 15.

[0024] The plurality of solar cell modules 16 are arranged side by side along the longitudinal direction of the rafter member 15. Furthermore, the plurality of solar cell modules 16 may be arranged side by side along the width direction. As shown in FIG. 4 , the solar cell module 16 includes a solar cell panel 18 and a frame 19. The solar cell panel 18 is a rectangular plate. The frame 19 surrounds the outer edge of the light-receiving surface lrs of the solar cell panel 18. The light-receiving surface lrs may be formed on one of the main surfaces of the solar cell panel 18. The main surface may be the surface of the solar cell panel 18 that has the largest area.

[0025] As shown in FIG. 5 , the frame 19 may have a side portion 20, a clamping portion 21, and a fixing portion 22. The side portion 20 covers the side of the solar cell panel 18. The side portion 20 may be longer than the thickness of the solar cell panel 18. The side portion 20 may protrude on the side opposite the light-receiving surface lrs of the solar cell panel 18. The clamping portion 21 may clamp the vicinity of the outer edge of the main surface of the solar cell panel 18 along the thickness direction of the solar cell panel 18. The fixing portion 22 may be frame-shaped when viewed from the normal direction of the light-receiving surface lrs. The fixing portion 22 may be a portion that has a width inward of the frame at the end of the side portion 20 opposite the light-receiving surface lrs.

[0026] 6, the solar cell module 16 may be arranged such that the frame 19 overlaps the rafter member 15 when viewed from the normal direction of the light-receiving surface lrs. The solar cell module 16 may be fixed to the rafter member 15 in the frame 19 using a plurality of fastening members 23. The fastening members 23 are, for example, bolts and nuts.

[0027] In the solar cell module 16 located second or later from the first end e1 along the longitudinal direction of the rafter member 15, the frame 19, a portion of the first girder member 13, and the rafter member 15 may be positioned to overlap when viewed from the normal direction of the light-receiving surface lrs. In the solar cell module 16, the frame 19, the rafter member 15, and the multiple fastening members 23 may be positioned to overlap when viewed from the normal direction. Furthermore, at least one of the multiple fastening members 23 may be positioned closer to the first end e1 than the center of the first girder member 13 when viewed from the normal direction. The center of the first girder member 13 is the center of the rafter member 15 in the longitudinal direction. The at least one other fastening member 23 may be positioned closer to the second end e2 than the center of the first girder member 13 when viewed from the normal direction.

[0028] As shown in FIG. 7 , in the solar cell module 16 located first from the second end e2 along the longitudinal direction of the rafter member 15, the frame 19, a portion of the second girder member 14, and the rafter member 15 may be positioned to overlap when viewed from the normal direction of the light-receiving surface lrs. In the solar cell module 16, the frame 19, the rafter member 15, and multiple fastening members 23 may be positioned to overlap when viewed from the normal direction. Furthermore, at least one of the multiple fastening members 23 may be positioned closer to the first end e1 than the center of the second girder member 14 when viewed from the normal direction. The center of the second girder member 14 is the center of the rafter member 15 in the longitudinal direction. The at least one other fastening member 23 may be positioned closer to the second end e2 than the center of the second girder member 14 when viewed from the normal direction.

[0029] As shown in FIG. 3 , the connecting member 17 may extend in the second direction. The connecting member 17 may have a flat portion. The connecting member 17 may connect multiple rafter members 15. The connecting member 17 may be located below the rafter members 15. The flat portion of the connecting member 17 may be in surface contact with the flat portion of the rafter member 15 to fix the rafter member 15. The connecting member 17 may be provided at any position in the first direction. For example, the connecting member 17 may be provided at the first end e1, the second end e2, or between the first end e1 and the second end e2.

[0030] The carport 10 with solar cells configured as described above includes at least one set of a first column member 11 and a second column member 12 that are erected on the installation surface is and separated from each other in a first direction, a first girder member 13 and a second girder member 14 that extend in the axial direction of the first column member 11 and in a second direction perpendicular to the first direction and are respectively fixed to the first column member 11 and the second column member 12, at least one purlin member 15 that is arranged to be perpendicular between both ends in the longitudinal direction of the first girder member 13 and the second girder member 14, a plurality of solar cell modules 16 that are arranged side by side along the longitudinal direction of the purlin member 15 and each have a rectangular solar cell panel 18 and a frame 19 that surrounds the outer edge of the light-receiving surface lrs of the solar cell panel 18, and the frame 19 is fixed to the purlin member 15 using a plurality of fastening members 23. Taking the total length of the purlin member 15 in the longitudinal direction as L, the length in the longitudinal direction of the portion from the first end e1 to the first girder member 13, which is located on the first end e1 side from the second girder member 14 in the longitudinal direction of the purlin member 15, as L1, the length along the longitudinal direction of the portion of the purlin member 15 sandwiched between the first girder member 13 and the second girder member 14 as L2, and the length in the longitudinal direction of the portion from the second end e2 to the second girder member 14 in the longitudinal direction of the purlin member 15 as L3, it satisfies L / 4 < L1, 0 < L3, and L1 < L2. In the following description, in order to explain the effects exhibited by the carport 10 with solar cells, as shown in FIG. 8, in the longitudinal direction of the purlin member 15, the portion from the first end e1 to the first girder member 13 in the longitudinal direction of the purlin member 15 is, for convenience, described as the first portion p1. Also, the portion of the purlin member 15 sandwiched between the first girder member 13 and the second girder member 14 is, for convenience, called the second portion p2. Also, the portion from the second end e2 to the second girder member 14 in the longitudinal direction of the purlin member 15 is, for convenience, called the third portion p3. The carport 10 with solar cells having the above-described configuration, due to the feature that L / 4 < L1, the length of the second portion p2 is sufficiently small with respect to the length of the entire purlin member 15 in the longitudinal direction.Therefore, in the carport 10 with solar cells, the vertical downward (counterclockwise in FIG. 8) bending moment applied to the first portion p1 with the first girder member 13 as the fulcrum is larger than the vertical downward (clockwise in FIG. 8) bending moment applied to the second portion p2 with the said fulcrum. Due to the difference in the magnitudes of the bending moments, the carport 10 with solar cells causes rotational displacement in the entire first portion p1 and second portion p2, with the first portion p1 side moving vertically downward and the second portion p2 moving vertically upward. Thus, the carport 10 with solar cells causes a deflection convex upward vertically in the second portion p2. Since the carport 10 with solar cells satisfies L1 < L2, L1 is not overly long, so plastic deformation at the intersection of the purlin member 15 and the first girder member 13 can be reduced without using other members or the like for strength improvement. Therefore, in the carport 10 with solar cells, since plastic deformation of the purlin member 15 at the intersection with the first girder member 13 is reduced, a rotational moment can be generated to rotate the above-mentioned second portion p2 vertically upward. Also, since the carport 10 with solar cells satisfies 0 < L3, a deflection convex upward vertically is caused in the second portion p2. Thus, with a simple structure, the carport 10 with solar cells has the second portion p2 convex upward vertically as a whole, thereby improving the drainage performance in the second portion p2. As a result, the carport 10 with solar cells can suppress a decrease in the power generated by dirt such as dust due to evaporation of rainwater accumulated in the second portion p2.

[0031] Furthermore, the carport 10 with a solar cell having the above-described configuration can position the first column member 11 and the second column member 12 on the side of the second end e2 due to the feature that L3 < L1. In the carport 10 with a solar cell, parking with the first end e1 side facing forward is assumed. In response to such an assumption, the carport 10 with a solar cell can reduce the possibility of interference between the first column member 11 and the second column member 12 and the vehicle door when it opens and closes. Also, due to the above-described configuration, the carport 10 with a solar cell can reduce the bending moment generated in the second portion p2 compared to the configuration where L3 = L1. Therefore, the carport 10 with a solar cell can suppress plastic deformation in the second portion p2 without using other members or the like for strength improvement.

[0032] Furthermore, in the carport 10 with a solar cell, in the solar cell module 16 located second and subsequent from the first end e1 along the longitudinal direction of the purlin member 15, the frame 19, the first girder member 13, and the purlin member 15 are positioned overlapping when viewed from the normal direction of the light receiving surface lrs, and the frame 19, the purlin member 15, and the plurality of fastening members 23 are positioned overlapping when viewed from the normal direction, and at least one of the plurality of fastening members 23 is positioned on the first end e1 side from the center of the first girder member 13 when viewed from the normal direction, and the other fastening members 23 are positioned on the second end e2 side from the center of the first girder member 13 when viewed from the normal direction. With such a configuration, the carport 10 with a solar cell can cause the purlin member 15 and the frame 19 to cooperate, so as to further reduce plastic deformation in the portion of the purlin member 15 that intersects the first girder member 13. Therefore, the carport 10 with a solar cell can make the length L1 of the first portion p1 relatively long, without using another member or the like for strengthening the purlin member 15, and can also reduce the weight of the purlin member 15. Also, the carport 10 with a solar cell can improve the strength against snow load, wind load, etc. for the solar cell module 16.

[0033] In the solar cell-equipped carport 10, at the solar cell module 16 located first from the second end e2 along the longitudinal direction of the rafter member 15, the frame 19, second girder member 14, and rafter member 15 are positioned overlapping when viewed from the normal direction of the light-receiving surface lrs, and the frame 19, rafter member 15, and multiple fastening members 23 are positioned overlapping when viewed from the normal direction, with at least one of the multiple fastening members 23 positioned closer to the first end e1 than the center of the second girder member 14 when viewed from the normal direction, and the other fastening members 23 positioned closer to the second end e2 than the center of the second girder member 13 when viewed from the normal direction. With this configuration, the solar cell-equipped carport 10 can make the rafter member 15 and the frame 19 work together, further reducing plastic deformation in the portion of the rafter member 15 that intersects with the second girder member 14. Therefore, the carport with solar cells 10 can form the length L3 of the third portion p3 relatively long without using any other member to strengthen the rafter member 15, and can reduce the weight of the rafter member 15. Furthermore, the carport with solar cells 10 can improve the strength of the solar cell module 16 against snow load, wind load, etc.

[0034] Furthermore, in the solar-cell carport 10, the rafter members 15 have an H-shaped cross section perpendicular to the longitudinal direction. As shown in FIG. 9, if the cross section of the rafter members 15' in the carport 10' is not symmetrical with respect to a plane parallel to the vertical direction, such as a C-shaped steel beam, the rafter members 15' may bend due to loads from above and laterally. As a result, the solar cell module 16' forming the roof may bend vertically downward. In response to such an event, the solar-cell carport 10 having the above-described configuration can reduce the possibility of twisting of the rafter members 15. Therefore, the solar cell carport 10 can reduce the possibility of rainwater stagnation due to the solar cell module 16 bending vertically downward.

[0035] In the carport 10 with solar cells, at least one rafter member 15 includes a plurality of rafter members 15 arranged along the second direction, and the plurality of rafter members 15 are connected to a connecting member 17 extending in the second direction. With such a configuration, the carport 10 with solar cells can reduce the possibility of twisting about a straight line parallel to the longitudinal direction in the rafter member 15. Therefore, the carport 10 with solar cells can reduce the possibility of rainwater retention due to the solar cell module 16 deflecting vertically downward.

[0036] In one embodiment, (1) the carport with solar cells includes at least one set of a first pillar member and a second pillar member that are erected on the installation surface at a distance from each other in the first direction, a first girder member and a second girder member that extend in the axial direction of the first pillar member and in a second direction perpendicular to the first direction, and are respectively fixed to the first pillar member and the second pillar member, at least one rafter member that is arranged so as to be orthogonal between both ends in the longitudinal direction with respect to the first girder member and the second girder member, a plurality of solar cell modules that are arranged side by side along the longitudinal direction of the rafter member, each having a rectangular solar cell panel and a frame surrounding the outer edge of the light receiving surface of the solar cell panel, and being fixed to the rafter member in the frame using a plurality of fastening members, Regarding the total length of the rafter member in the longitudinal direction as L, the length in the longitudinal direction of the portion from the first end in the longitudinal direction of the rafter member to the first girder member located on the first end side of the second girder member as L1, the length along the longitudinal direction of the portion of the rafter member sandwiched between the first girder member and the second girder member as L2, and the length in the longitudinal direction of the portion from the second end in the longitudinal direction of the rafter member to the second girder member as L3, L / 4 < L1, 0 < L3, and L1 < L2 are satisfied.

[0039] (4) In any of the solar-powered carports (1) to (3) above, In the solar cell module located first from the second end along the longitudinal direction of the rafter member, the frame, the second beam member, and the rafter member are positioned to overlap when viewed from the normal direction of the light-receiving surface, and the frame, the rafter member, and the multiple fastening members are positioned to overlap when viewed from the normal direction; At least one of the plurality of fastening members is located closer to the first end than the center of the second beam member when viewed from the normal direction, and the other fastening members are located closer to the second end than the center of the second beam member when viewed from the normal direction.

The configurations remain distinguished even after the exchange of identifiers. Identifiers may be deleted. A configuration from which an identifier has been deleted is distinguished by a symbol. The descriptions of identifiers such as "first" and "second" in this disclosure should not be used solely to interpret the order of the configurations or to justify the existence of an identifier with a smaller number.
