Description

Technical Field

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

[0002] In solar power generation systems that use solar cell modules, it is necessary to make full use of sunlight in order to increase power generation. Therefore, it is becoming increasingly common to install solar cell modules on the roofs of well-lit residences and building rooftops. However, in recent years, it has been proposed to install solar cell modules on the roof of carports (for example, Patent Document 1).

[0003] In the carport with solar cell modules in Patent Document 1, the longitudinal beams are supported by a pair of pillars that slope downwards from the front of the parking lot toward the rear. These pillars serve as retaining members for multiple crossbeams, holding each of the multiple solar cell modules in a manner that is longitudinally seamless and laterally spaced along the crossbeams.

[0007] Technical issues

[0008] Typically, in the construction of back-to-back parking garages (where two cars are parked back-to-back), the length of the upper crossbeam (longitudinal rail) supporting the solar panels that serve as the roof needs to be approximately 10-12 meters to cover the entire length of two cars. However, using a single, integrated upper crossbeam would cause inconvenience in manufacturing, transportation, and construction. Therefore, an upper crossbeam is constructed by splicing multiple components together with connectors. However, water from condensation sometimes drips from the joints between these components. Additionally, rainwater flowing over the top of the crossbeam seeps into the components through tiny gaps at the joints and drips from below. In this case, waterproofing is achieved by applying a sealant to the inner surface of the recessed areas at the joints, which is time-consuming. Thus, in conventional carports, because the crossbeams are composed of multiple components, leaks can still occur even with a roof.

[0009] The present invention was made in view of the above-mentioned technical problems, and its object is to provide a carport in which rainwater and the like can be prevented from leaking between adjacent components without waterproofing the connection points when the crossbeam is composed of multiple components.

[0010] Problem-solving methods

[0011] The carport of the present invention is characterized by comprising: a roof component in which a plurality of solar cell modules are arranged along a first direction and a second direction intersecting the first direction; a first crossbeam arranged along the first direction and inclined in the first direction, the first crossbeam comprising a plurality of crossbeam components and connecting components, the crossbeam component comprising: a columnar portion having a hollow portion formed therein along its length; a pair of sidewalls arranged along the length of the upper surface of the columnar portion at the width of the upper surface; the connecting components connecting adjacent crossbeam components to each other by fitting into the hollow portion of the crossbeam components, the upper surface of the columnar portion and the pair of sidewalls forming a recess, and at both ends of the upper surface of the connecting component in the width direction, vertical portions are respectively provided covering the length of the connecting component, the vertical portions being configured to be higher than the lowest position of the upper surface of the connecting component.

[0012] In the carport of the present invention, the first crossbeam includes multiple crossbeam components and connecting components. The crossbeam components include: a columnar portion having a hollow portion formed inside along its length; and a pair of sidewalls disposed along the length of the edge portion of the upper surface of the columnar portion in the width direction. The connecting components connect adjacent crossbeam components to each other by fitting into the hollow portion of the crossbeam components. At both ends of the upper surface of the connecting components in the width direction, vertical portions are respectively provided covering the length direction of the connecting components. The vertical portions are configured to be higher than the lowest position of the upper surface of the connecting components. Thus, even if water seeps into the crossbeam components from the connection position between the crossbeam components, the water will remain in the gap on the concave side of the connecting components. Therefore, it is not necessary to waterproof the connection position to prevent water from dripping from the connection position of the crossbeam components to the area directly below the carport.

[0013] Preferably, the crossbeam component further includes a side hollow portion continuous with the hollow portion within the side wall portion, and the upright portion is a connecting wall portion that fits into the side hollow portion. With this structure, the connecting component and the crossbeam component are sufficiently fixed, and the connecting component fits into the side hollow portion, thereby forming a gap wall surface. Therefore, it is possible to further suppress water from moving outwards from the connection position of the crossbeam component and dripping directly below the carport.

[0014] Preferably, the depth of the recess is 20–50 mm. With a depth of 20–50 mm, fallen leaves will not adhere to the recess and will easily slide off, allowing the recess to function more effectively as a drainage path.

[0015] Preferably, a side gap is provided between the inner wall surface of the hollow side portion constituting the side wall and the connecting wall surface. Furthermore, it is preferable that a recess is provided on the upper surface of the side wall. By providing the side gap and recess in this way, water ingress into the joint due to capillary action can be suppressed.

[0016] The effects of the invention

[0017] According to the carport of the present invention, when the crossbeam is composed of multiple components, leakage of rainwater and the like from adjacent components can be prevented without waterproofing the connection points. Attached Figure Description

[0028] The carport according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings. However, this embodiment is exemplary, and the present invention is not limited thereto.

[0029] Furthermore, the terms "first," "second," and "third" used in this specification are only used to distinguish a structural element from other structural elements, and are not used to limit the number, order, or priority of the structural elements. For example, the presence of "first structural element" and "second structural element" does not mean that only these two structural elements are used, nor does it mean that "first structural element" must precede "second structural element." Additionally, in each embodiment, the same reference numerals are used to label identical components, but when differentiating identical components by their placement position, letters such as a, b, etc., are added to the reference numerals for distinction.

[0030] (First Implementation)

[0031] use Figures 1-5 The carport 1 of the first embodiment will be described. In this embodiment, the carport 1 includes a support column 11, a lower crossbeam 12 and an upper crossbeam (first crossbeam) 13 as supporting components, and a roof component, which is composed of a plurality of solar cell modules 14 that function as the roof of the carport 1.

[0032] In this embodiment, the support column 11 along Figure 1 The first direction is arranged in four columns, and the second direction, orthogonal to the first direction, is arranged in three columns, thus a total of 12 supports are vertically erected on the ground. Four lower crossbeams 12 cover the three supports 11 erected along the second direction and are respectively fixed to the supports 11. That is, in the carport 1, as shown... Figure 3 As shown, the two lower crossbeams 12a and 12b are fixed to the three supports 11 respectively via connectors 111a and 111b in a parallel manner along the second direction. At this time, the connector 111a of the lower crossbeam 12a is adjusted to a desired height higher than the connector 111b of the lower crossbeam 12b. Therefore, the lower crossbeam 12a is fixed at a position higher than the lower crossbeam 12b.

[0033] Furthermore, for these two lower crossbeams 12a and 12b, the 13 upper crossbeams 13 parallel to each other along the first direction, while mounted on the lower crossbeams 12a and 12b, are connected by connecting parts 121a and 121b (see reference). Figure 3 The upper beams 12a and 12b are fixed to the upper part of the lower crossbeams 12a and 12b. The 13 upper crossbeams 13 are separated from each other at specified intervals. The lower crossbeams 12a and 12b are along the second direction, and the upper crossbeams 13 are along the first direction. Therefore, when viewed from above, the upper crossbeams 13 and the lower crossbeams 12 are at right angles.

[0034] A rectangular solar cell module 14, which appears rectangular when viewed from above, is fixed on the upper crossbeam 13. In this embodiment, the solar cell modules 14 are arranged in five rows along a first direction and twelve columns along a second direction. Specifically, each long side of the solar cell module 14 rests on the upper crossbeam 13 and is mounted between adjacent upper crossbeams 13.

[0035] The upper crossbeam 13 is inclined in the first direction, thus, as Figure 3 As shown, each solar cell module 14 is configured to be continuously tilted in the first direction. Additionally, Figure 3 In this configuration, the same solar cell module is sequentially designated as solar cell modules 14a, 14b, and 14c from the top inclined side. That is, in the carport 1, the solar cell modules are respectively configured as follows: solar cell module 14a... Figure 3 The highest point is at the middle left end, with a 14c solar cell module. Figure 3 The rightmost end is the lowest. This configuration ensures that, in the event of rainfall, water flows along the inclined direction, i.e., rainwater flows from the solar cell module 14a located on the upper inclined side to the solar cell module 14c located on the lower inclined side along the surface of each solar cell module 14.

[0036] In addition, in this embodiment, for ease of explanation, the lower crossbeams 12a and 12b are assumed to be a rod-shaped component extending in the second direction. For example, the lower crossbeams 12a and 12b may also be used to join two or more short rod-shaped components together.

[0037] The upper crossbeam 13 is mounted on the lower crossbeams 12a and 12b. Since the connector 111a of the lower crossbeam 12a is adjusted to a desired height higher than the connector 111b of the lower crossbeam 12b, each upper crossbeam 13 mounted on the lower crossbeams 12a and 12b is also tilted in a manner where it is higher on the side of the lower crossbeam 12a and relatively lower on the side of the lower crossbeam 12b, and is fixed to the lower crossbeams 12a and 12b. That is, the upper crossbeam 13 is fixed in a tilted manner in a first direction. The tilt from the side of the lower crossbeam 12a to the side of the lower crossbeam 12b is defined as the tilt direction in this embodiment, with the higher side designated as the tilted upper side and the lower side designated as the tilted lower side.

[0038] A certain gap is left between each solar cell module 14. This is to accommodate the dimensional tolerances of the solar cell modules 14 themselves, and also to prevent the solar cell modules 14 from contacting each other due to swinging or vibration. The upper crossbeam 13 is aligned with this gap. The upper crossbeam 13 is composed of two crossbeam components 20 in the first direction, and the crossbeam components 20 are connected by fitting connecting components 30. That is, as shown... Figure 5As shown, crossbeam components 20a and 20b are connected by a connecting member 30 to form an upper crossbeam 13. Furthermore, each crossbeam component 20 has a recess 40 formed on its upper surface. By connecting the upper crossbeam 13 with the connecting member 30, the recess 40 functions as a continuous rainwater channel on the upper crossbeam 13. Rainwater flows through the recesses 40 of each crossbeam component 20 and is discharged from the lower end of the lowest-positioned crossbeam component 20.

[0039] use Figures 6-8 The structure of the beam member 20 and connecting member 30 constituting the upper beam 13 will be described. The beam member 20 constituting the upper beam 13 includes a columnar portion 22, which is a hollow prism with a hollow portion 21 formed inside along its length direction. On the columnar portion 22, a pair of sidewalls 23 cover the edge portion 222 in the width direction of its upper surface 221 in the length direction. Plate-like portions 231 are respectively provided on the upper part of the sidewalls 23. The plate-like portions 231 are formed such that their upper surface is parallel to the bottom surface of the upper beam 13, and the solar cell assembly 14 is mounted on the plate-like portions 231. The recess 40 is divided by the pair of sidewalls 23 and the upper surface 221 of the columnar portion 22.

[0040] Hollow side portions 24 are also formed inside each side wall 23. The hollow side portions 24 and hollow portions 21 are continuous, forming a hollow region 25 within the beam member 20. The columnar portion 22 covers the corners on both sides of the bottom surface 223 in the width direction and is provided with reinforcing portions 224 for reinforcement. Therefore, the hollow portion 21 is approximately hexagonal in cross-sectional view, and hollow end portions 225 are also formed between each reinforcing portion 224 and the columnar portion 22. In addition, the two ends of the beam member 20 are open, so the hollow region 25 is also open at both ends of the beam member 20.

[0041] The connecting member 30 is configured to connect adjacent crossbeam members 20 to each other by fitting into the hollow region 25. Therefore, the connecting member 30 is configured with a shape corresponding to the hollow region 25. Specifically, the connecting member 30 consists of a connecting main body portion 31 and a pair of connecting wall portions 32. The connecting main body portion 31 is approximately hexagonal in frontal view and is configured to be inserted into the hollow portion 21; the pair of connecting wall portions 32 are provided on the upper surface 311 of the connecting main body portion 31 and are configured to be inserted into the side hollow portion 24. The pair of connecting wall portions 32 are formed covering the length direction of the connecting member 30.

[0042] When the connecting member 30 is inserted into adjacent crossbeam members 20 to engage them, the connecting member 30 is inserted into the hollow region 25 of one crossbeam member 20a. In this state, the opposite end of the connecting member 30 is inserted into the hollow region 25 of another crossbeam member 20b. This secures the adjacent crossbeam members 20 to each other. In this case, the recess 40 becomes partially discontinuous at the boundary between the crossbeam members 20a and 20b, and the connecting member 30 is exposed at this boundary portion.

[0043] In addition, such as Figure 8 As shown, the two can be further securely fixed by the fixing member 33. Furthermore, when the connecting member 30 is inserted into the crossbeam member 20, a gap 41 is formed between the crossbeam member 20 and the connecting member 30 as a clearance between the members. The gap 41 is U-shaped around the recess 40. As explained below, this gap 41 between the crossbeam member 20 and the connecting member 30 functions as a rainwater channel.

[0044] use Figure 5 and Figure 9 This illustrates how rainwater flows from the upstream side to the downstream side of the upper crossbeam 13 during rainfall. Figure 5 For ease of understanding, the inclination of the upper crossbeam 13 is not shown, but the upper side of the inclination is the left side of the figure, and the right side of the inclination is the right side of the figure. Starting from the upstream side of the upper crossbeam 13, let the area in crossbeam component 20a where the connecting component 30 is not inserted be region A, the area in crossbeam component 20a where the connecting component 30 is inserted be region B, the area in crossbeam component 20b where the connecting component 30 is inserted be region C, and the area in crossbeam component 20b where the connecting component 30 is not inserted be region D. Each region is respectively associated with... Figure 9 The regions (A) to (D) correspond. Region A is located at the upstream end, and region D is located at the downstream end.

[0045] In regions A and B, such as Figure 9 As shown, regardless of the presence or absence of the connecting member 30, water W flows from the upstream side to the downstream side within the recess 40. Furthermore, when water W moves from region B to region C, most of the water W flows directly within the recess 40, but some may leak downwards and / or laterally from the joint (discontinuous portion, connection point) between the beam members 20a and 20b. However, in this embodiment, since the connecting member 30 exists between the beam members 20a and 20b, and in this embodiment, the connecting member 30 is configured to have a gap 41 between the connecting member 30 and the beam member 20, even if water leaks from the recess 40, the water W will move within this gap 41.

[0046] In the water W flowing from region C to region D, the water W flowing through the recess 40 in region D passes directly through the recess 40. On the other hand, since there is no connecting member 30 starting from region D, the water W flowing through the gap 41 in region C falls directly into the hollow part 21 of the beam member 20 and flows within the hollow part 21, and is discharged outward on the downstream side.

[0047] In the case where two crossbeam components 20 are connected to form an upper crossbeam 13 as in this embodiment, if the connecting member 30 of the present invention is not provided and the crossbeam components 20 are connected to each other, it is conceivable that rainwater will leak downwards between the crossbeam components 20a and 20b. However, in this embodiment, since the crossbeam components 20a and 20b are connected by the connecting member 30, and a gap 41 is formed by the connecting member 30, which functions as a rainwater channel allowing water to flow below the recess 40, water leakage from the upper crossbeam 13 inside the carport 1 can be suppressed without waterproofing the connection point. Furthermore, even if water leakage occurs between the crossbeam components 20a and 20b due to hydrostatic pressure, the water pressure difference will disappear when the water level in the gap 41 becomes equal to the water in the recess 40, thereby preventing water leakage from the recess 40.

[0048] Furthermore, by inserting a connecting wall surface 32 into the side hollow portion 24 formed within the side wall 23, the connecting wall surface 32 becomes a wall surface, making it difficult for water W in the gap 41 to leak to the outside. Therefore, it is excellent in suppressing water leakage.

[0049] Preferably, the depth of the recess 40 is 20 to 50 mm. By setting it within this range, fallen leaves are less likely to adhere to the recess 40 and will easily slide off, allowing the recess 40 to function more effectively as a drainage channel. More preferably, the depth of the recess 40 is 30 to 50 mm, and in this embodiment it is 34 mm.

[0050] (Second Implementation)

[0051] Figure 10 This indicates a second embodiment of the present invention. In the second embodiment, the same structural elements as in the first embodiment are labeled with the same reference numerals.

[0052] The second embodiment differs from the first embodiment in that, in the inner wall surface of the hollow portion 24 on the side of the side wall 23, a side gap 52 larger than the free clearance is provided between the inner wall surface 51 on the recess 40 side and the connecting wall surface 32. Furthermore, recesses 53 are provided on the plate-like portions 231 at the upper part of each pair of side walls 23. By setting the side gap 52 to a size larger than the free clearance and to a degree that does not produce capillary action, it is possible to retain water (… Figure 10(Not shown in the figure) Simultaneously, it suppresses water leakage from the upper end of the connecting wall surface 32 to the inner wall surface 54 of the side wall 23, which corresponds to the upper surface, due to capillary action. Even without the recess 53 on the upper surface 231 of the side wall 23, although the upper surface 231 and the lower surface of the outer contour frame of the solar cell assembly 14 are in close contact, there is actually a small gap due to the unevenness of the contact surface. Therefore, this gap is considered to be a cause of capillary action, causing water that should flow into the recess 40 to leak outward from the upper surface 231 through the small gap due to capillary action. In this embodiment, by providing the recess 53 on the upper surface 231 of the side wall 23, this capillary action can be blocked, thereby also suppressing water leakage from the upper surface 231 to the outside.

[0053] Furthermore, the crossbeam member 20 is configured such that the side gap 52 is formed to cover the mating area of ​​the crossbeam member 20 and the connecting member 30. In order to form the side gap 52, in this embodiment, the side wall 23 of the crossbeam member 20 is thicker than in the first embodiment, and as a result, the side wall 23 protrudes toward the recess 40.

[0054] The recess 53 may be provided to cover the entire length of the plate-shaped portion 231, or it may be provided only around the seam. Alternatively, multiple recesses 53 may be provided separately along the length of the connecting member 30, or they may be provided separately along the width of the connecting member 30.

[0055] Specifically, the width of the distance between the inner wall surface 51 and the connecting wall surface 32 on the side of the recess 40, i.e., the width of the side gap 52, is, for example, 2 to 10 mm, preferably 3 to 5 mm, and in this embodiment, 3 mm. If the width is greater than 10 mm, it has the advantages of being able to retain a larger water volume and suppressing capillary action, but there is a concern that the width of the crossbeam component 20 becomes too large, leading to an increase in the price of the crossbeam component 20. On the other hand, if the width is narrower than 2 mm, there is a concern that the effect of suppressing capillary action will be smaller. In addition, the width of the recess 53 is structurally, for example, 2 mm to 10 mm, and in this embodiment, 3 mm. The depth of the recess 53 is structurally, for example, 2 mm to 10 mm, and in this embodiment, 3 mm. In this embodiment, the recess 53 is generally rectangular when viewed in cross-section, but it is not limited to this; for example, it may also be arc-shaped.

[0056] The carport 1 of the present invention has been described above, but the carport 1 of the present invention is not limited to the embodiments described above. In each of the above embodiments, the connecting member 30 is configured to have a connecting wall portion 32, but it is only necessary to form a pair of upright portions at both ends of the upper surface 311 of the connecting member 30 in the width direction, and the upright portions are configured to be higher than the lowest position of the upper surface 311. For example, the following structure can be listed: without the connecting wall portion 32, and in cross-sectional view in the length direction, having upright portions with a low center and high ends on the upper surface 311 of the connecting member, and the upper surface 311 of the connecting member is curved in shape overall. In addition, for example, the shape of the hollow portion 21 is not limited, and it can be configured to be wider without the reinforcement portion 224. In addition, it can be configured to have a groove recessed relative to the upper surface on the upper surface of the connecting member 30 to increase the gap 41 with a larger volume.

[0057] Furthermore, the shape of the hollow part 24 on the side is not limited.
