Description

Technical Field

[0001] The present invention relates to the field of buildings, and in particular to a prefabricated photovoltaic building integrated large-span space structure system and method. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The development of green and low-carbon has become a global consensus and trend. As a clean and renewable energy technology, it has significant environmental protection advantages. However, the current utilization rate of photovoltaics in buildings is still relatively low, especially the application of the combination of large-span space structures and photovoltaics is still less. The main reason is that the structural strength is limited, and as a roof structure, there are relatively high requirements for the strength and seismic performance of the structure. In some solutions, the large-span space structure is also combined with the photovoltaic system, but the strength at the connection nodes is poor, and the photovoltaic structure is added later, resulting in poor seismic performance when the whole structure is used as the top surface structure of a stadium, etc.; moreover, in the prior art, the space components are simply combined without considering the sealing performance of the overall structure as a roof structure, resulting in water leakage problems on the top surface of large buildings in applications;

[0004] In addition, the existing brackets for supporting solar panels are all cut and welded on site without prefabrication in advance. Summary of the Invention

In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof;

[0074] As introduced in the background art, for the problems in the prior art, in order to solve the above technical problems, the present invention proposes an assembled photovoltaic building integrated large-span space structure system.

[0075] Embodiment 1

[0076] In a typical implementation manner of the present invention, referring to Figure 1 , Figure 2 shown, an assembled photovoltaic building integrated large-span space structure system includes multiple support structures, each support structure is detachably connected, each support structure includes multiple support units, and the multiple support units are detachably assembled into a support structure, and each support unit supports a photovoltaic module respectively;

[0077] The support unit includes multiple load-bearing members. Between two adjacent load-bearing members in the support unit, they are connected by support rods or welded together through middle connectors. Each side of the connection frame is supported by multiple load-bearing members. The connection frame has at least three sides. The connection frame is provided with grooves to support the photovoltaic modules. Column-wheel nodes are respectively arranged at each corner of the support unit. The ends of the load-bearing members are connected to the column-wheel nodes. All the support units in the support structure can be commonly connected to a central column-wheel node. The outer ends of two adjacent load-bearing members of two adjacent support units in the support structure are connected to the same column-wheel node. Multiple support structures are assembled into an integrated long-span space structure system through the column-wheel nodes.

[0078] In this embodiment, the load-bearing member I is specifically a rectangular hollow pipe, which is the main component of the integrated photovoltaic roof panel structure system. The width direction of the rectangular hollow pipe is used to contact the connection frame. Refer to Figure 5 As shown, at both ends of the load-bearing member I, there are clamp-type connecting plates I-1 that match the connecting ear plates of the node. The cross-section of the clamp-type connecting plate I-1 is rectangular. An opening groove is provided on the side of the clamp-type connecting plate I-1 away from the body of the load-bearing member. A tenth bolt hole I-4 is provided at the clamp-type connecting plate I-1. The thickness of the clamp-type connecting plate I-1 is less than the thickness of the body of the load-bearing member 1. The clamp-type connecting plate is used to connect with the connecting ear plate on the column-wheel node VII. A number of equally spaced first bolt holes I-3 are provided on the top and bottom surfaces of the rectangular hollow pipe for connecting the lightweight connection frame V. A second bolt hole I-2 is provided at the center of the side surface for connecting the U-shaped sleeve (if the rectangular hollow pipes are connected by welding to form a triangular frame, there is no need to provide bolt holes at the center of the side surface).

[0079] Refer to Figure 6 As shown, the transfer member II is specifically a U-shaped sleeve. The transfer member specifically includes two side plates. The two side plates are connected by a connecting plate so that the cross-section of the U-shaped sleeve is U-shaped. Two first ear plates II-1 are provided on one side of the U-shaped sleeve. The two first ear plates are parallel to each other and perpendicular to the side surface of the U-shaped sleeve. A set of third bolt holes II-3 are provided on each first ear plate for connecting and fixing the U-shaped sleeve and the support rod; two fourth bolt holes II-2 are provided at the side parts of the two first ear plates of the U-shaped sleeve for connecting and fixing the rectangular hollow pipe.

[0080] Refer to Figure 7 As shown, the support rod III is rectangular and strip-shaped. Second ear plates are respectively provided at both ends. Fifth bolt holes III-1 are provided at the second ear plates for connecting with the first ear plates II-1 of the U-shaped sleeve, so that the connecting bolts pass through the first ear plate and the second ear plate.

[0081] Refer to Figure 9As shown, the shape of the connecting frame V is similar to a triangle, specifically close to an equilateral triangle. The connecting frame V includes three side edges, which are respectively located on the three sides of the triangle. The adjacent side edges are not connected. Each side edge of the connecting frame is provided with a plurality of sixth bolt holes V-2 for connecting the corresponding stressed member I. The width of the side edge of the connecting frame is greater than the width of the stressed member. Moreover, a stepped section is provided on the upper surface of each side edge of the connecting frame so that the connecting frame is provided with a groove V-1. The photovoltaic module VI is placed through the groove. The Y-shaped support frame V-4 has three sides, and each side of the Y-shaped support frame is respectively connected to the corresponding side edge. The photovoltaic module is supported and fixed by the Y-shaped support frame V-4. A number of seventh bolt holes V-3 are drilled on each side of the Y-shaped support frame for connecting with the photovoltaic module.

[0082] To match the shape of the connecting frame, a triangular photovoltaic module is specifically selected. Each corner of the photovoltaic module is set as a plane. It can be understood that the column structure of the photovoltaic module is an existing solar panel.

[0083] Reference Figure 10 As shown, a Y-shaped connecting member VI-2 is provided in the middle of the photovoltaic module VI. The Y-shaped connecting member VI-2 is provided with a number of eighth bolt holes VI-1 for connecting with the Y-shaped support frame V-4 of the connecting frame V.

[0084] In other examples, a first magnet is provided on the Y-shaped connecting member of the photovoltaic module, and a second magnet is provided on the Y-shaped support frame of the connecting frame. The first magnet and the second magnet can be attracted to each other to realize the fixation of the two.

[0085] Reference Figure 11 As shown, the wheel column node VII is specifically a double-ear plate type wheel column node. The wheel column node VII includes a hollow column body, specifically a regular hexagon hollow column body VII-4. Stiffening ribs VII-1 are provided inside the hollow column body. The stiffening ribs are provided in multiple places along the radial direction of the hollow column body. A pair of connecting ear plates VII-2 are provided on the outside of each side surface of the hollow column body. The connecting ear plates are perpendicular to the side surface of the hollow column body where they are located. A number of ninth bolt holes VII-3 are provided on each connecting ear plate for connecting with the clamp type connecting plate I-1. A total of 6 pairs of connecting ear plates are arranged on a regular hexagon hollow column body. Each pair of connecting ear plates are arranged parallel to each other. Moreover, the included angle between the adjacent two connecting ear plates on the adjacent two side edges of the hollow column body is 60°. The size of the connecting ear plate is adapted to the size of the opening groove of the clamp type connecting plate.

[0086] After the connecting frame is connected with the three stressed members, a support unit is formed. The support unit supports the photovoltaic module. Multiple support units can be assembled into a regular hexagon support structure. Multiple support structures can be assembled into a large-span space structure system. A cover plate IX is provided at the center of each support structure. Reference Figure 12As shown, the cover plate is a regular hexagon, and a seal VIII is provided between the cover plate and the support structure. The seal is specifically a rubber seal. Refer to Figure 13 As shown, the outer radius of the seal is the same as the radius of the middle notch of the formed support structure, and the inner radius of the seal is the same as the outer radius of the cover plate.

[0087] This embodiment also discloses an installation method for the integrated photovoltaic roof panel support system, including the following content:

[0088] First, place the U-shaped sleeve below the rectangular hollow tube and Figure 14 cover the rectangular hollow tube through the step ① shown. Then, align the two fourth bolt holes II-2 on the U-shaped sleeve with the two second bolt holes I-2 on the side of the rectangular hollow tube, and Figure 11 pass the two first bolts 1-1 into the bolt holes from one side and out from the other side, and then fix them with the first nuts 1-2. After installation, see Figure 15 as shown;

[0089] To fix the three rectangular hollow tubes and form a triangular frame structure, use the U-shaped sleeve and the support rod III to fix the three rectangular hollow tubes to form a stable triangular frame. The connection method is: Figure 16 After aligning the fifth bolt holes III-1 on the end ear plates of each support rod III with the third bolt holes II-3 on the ear plates of the U-shaped sleeve through the step ③ shown, and then Figure 16 pass the second bolt 2-1 into the corresponding bolt holes from one side and out from the other side, and then fix it with the second nut 2-2; refer to Figure 17 As shown, after connection, the included angle between the two support rods on each ear plate of the U-shaped sleeve is 60°, and the three support rods form a stable equilateral triangle structure, which can provide stable support for the triangular frame structure.

[0090] Refer to Figure 19 As shown, through step ⑤, align each sixth bolt hole V-2 on each side of the connection frame V with each first bolt hole I-3 on the upper surface of each rectangular hollow tube, and place the connection frame VI on the upper surface of the rectangular hollow tube. Then, Figure 19 pass the third bolt 3-1 corresponding to each bolt hole into the corresponding bolt hole from one side and out from the other side, and then fix it with the third nut 3-2. After connection, the Figure 20 support unit in

[0091] Refer to Figure 21As shown in the figure, the triangular photovoltaic module is adjusted in position through step ⑦ and placed inside the groove of the connection frame Ⅴ. At the same time, the eighth bolt hole Ⅵ-1 of the Y-shaped connection member Ⅵ-2 of the triangular photovoltaic module is aligned with the seventh bolt hole Ⅴ-3 of the Y-shaped support frame Ⅴ-4 of the connection frame. Then, through step ⑧, the fourth bolt 4-1 enters from one side of the corresponding bolt hole and passes through to the other side, and is fixed with the fourth nut 4-2. In this way, the connection frame and the triangular photovoltaic module can be connected and fixed. Refer to Figure 22 As shown in the figure, a triangular unit formed by connecting a photovoltaic module, a lightweight connection frame, and a rectangular hollow pipe is thus obtained.

[0092] Align the clamp-type connecting plate of the rectangular hollow pipe with the connecting ear plate of the wheel column node. Through Figure 16 In step ⑨ shown in the figure, insert the connecting ear plate into the opening groove of the clamp-type connecting plate, and align the tenth bolt hole Ⅰ-4 and the ninth bolt hole Ⅶ-3 of the two. Then, through Figure 23 In step ⑩ shown in the figure, the corresponding fifth bolt 5-1 enters from one side of the corresponding bolt hole and passes through to the other side, and is fixed with the fifth nut 5-2. In this way, refer to Figure 24 As shown in the figure, the two connecting ear plates on two adjacent sides of six adjacent sides of the wheel column node are connected to the ends of the stressed members in the same support unit. And so on, refer to Figure 25 As shown in the figure, a support system is finally formed.

[0093] Finally, through Figure 26 In step ⑪ in the figure, fix the seal at the middle notch above the hexagonal double-ear type wheel column node, so that the outer ring of the seal fits the notch. Then, through step ⑫, insert the regular hexagonal cover plate into the inner ring of the seal. After completion, the solar photovoltaic module, the cover plate, and the seal are on the same plane, so as to achieve the enclosure of each node of the long-span structure, achieve a good waterproof effect, and at the same time enable the separate disassembly of the photovoltaic module.

[0094] It can be understood that there is close contact between adjacent two support units in this application, and there is a certain sealing performance; further considering the overall sealing performance, adjacent two support units can be connected through existing adhesives.

[0095] Embodiment 2

[0096] The difference between this embodiment and Embodiment 1 is that:

[0097] The adjacent two sides of the support unit are connected through the middle connecting member, that is, the I-beam Ⅳ. Refer to Figure 8 As shown in the figure, the shapes of the upper flange and the lower flange of the I-beam are both trapezoidal. In this way, the formed structural system is shown in Figure 3 and Figure 4 As shown in the figure.

[0098] Specifically, the rectangular hollow tubes are fixed by welding to form a stable triangular frame, which includes the following: The I-beam Ⅳ is used to weld two adjacent rectangular hollow tubes with an included angle of 60°. Refer to Figure 18 As shown, after welding, the web section of the I-beam is connected to the side of the rectangular hollow tube to form a stable triangular frame structure. (Only this step of the welding method changes, and the remaining steps are the same as the connection method of the U-shaped sleeve and the support rod).

[0099] It should be noted that an assembled photovoltaic building integrated large-span space structure system provided by the present invention can be applied to the tops of buildings such as gymnasiums, swimming pools, and theaters. The side and bottom structures of gymnasiums, swimming pools, and theaters are not limited, but the top can adopt an assembled photovoltaic building integrated large-span space structure system in the present invention to assist municipal power supply and reduce power consumption requirements.
