Description

This new type of basketball court adopts a planar truss structure design, in which the columns, upper and lower chords, web members, and supporting components all utilize widely available rectangular tube cross-section materials. Because the truss span of this type of basketball court reaches 18 meters, the truss height is correspondingly large. Furthermore, it needs to withstand various vertical loads, including its own weight, snow load, and wind pressure, thus requiring each component to have large cross-sectional dimensions and thick walls. However, this directly leads to high construction costs and poor economic efficiency, thereby affecting its adoption rate in the industry. Faced with this challenge, how to reduce costs and improve the economics of photovoltaic rooftop systems has become a crucial issue that urgently needs to be addressed. Utility Model Content

The two ends of each web member are correspondingly connected to the two chords, and the two ends of each chord are correspondingly connected to the upper ends of the two columns.
[0016] The end of the tension cable is also connected to the end of the chord located below.
[0017] In one embodiment, the cross-section of the chord is rectangular, with the length of the long side being L1 and the length of the short side being L2, where 80mm ≤ L1 ≤ 100mm and 40mm ≤ L2 ≤ 50mm.

[0020] This utility model also proposes a photovoltaic sports field, which includes a photovoltaic roof system.

[0040] The photovoltaic basketball court adopts a planar truss structure design, with the columns, upper and lower chords, web members, and supporting components all using rectangular tube cross-section materials widely available in the market. Because the truss span of this type of basketball court reaches 18 meters, the truss height is correspondingly large. Furthermore, it needs to withstand various vertical loads, including its own weight, snow load, and wind pressure, thus requiring each component to have large cross-sectional dimensions and thick walls. However, this directly leads to high construction costs and poor economic efficiency, thereby affecting its adoption rate in the industry. Faced with this challenge, how to reduce costs and improve the economics of photovoltaic rooftop systems has become a crucial issue that urgently needs to be addressed.
[0041] This utility model proposes a photovoltaic roof system 100, which aims to reduce costs and improve the economic efficiency of the photovoltaic roof system while ensuring structural strength.
[0042] Please see Figures 1 to 3 In one embodiment of this utility model, the photovoltaic roof system 100 includes a plurality of truss structures 10 arranged longitudinally at intervals, and photovoltaic modules laid on top of the plurality of truss structures 10. Each truss structure 10 includes a support component, a crossbeam 2, a connecting component, and a tension cable 4. The support components are arranged longitudinally at intervals, and each support component includes at least two columns 1 extending vertically and spaced laterally. The crossbeam 2 extends laterally, and the two ends of the crossbeam 2 are aligned with the upper ends of the two columns 1. The connection should be made as follows: the connection assembly includes multiple support rods 3 extending vertically and spaced laterally, the upper ends of the support rods 3 being connected to the crossbeam 2; the tension cable 4 extends laterally and is located below the crossbeam 2, the two ends of the tension cable 4 being connected to the upper ends of the two columns 1 or the two ends of the crossbeam 2 respectively; wherein, the lower ends of the multiple support rods 3 are connected to the tension cable 4, and the upper and lower ends of the support rods 3 can be supported between the crossbeam 2 and the tension cable 4 respectively.
[0043] It is understood that the support components are arranged longitudinally at intervals, and each support component includes at least two columns 1, which extend vertically and are arranged laterally at intervals. The columns 1 are mainly used to support the truss structure 10 and transfer the load to the foundation.
[0044] The crossbeam 2 extends laterally, with its two ends connected to the upper ends of the two columns 1. The crossbeam 2 is the main load-bearing component, responsible for supporting the photovoltaic modules above and resisting external loads through its rigidity.
[0045] The connecting assembly consists of multiple support rods 3, which extend vertically and are spaced laterally. The upper end of each support rod 3 is connected to the crossbeam 2, while the lower end is connected to the tension cable 4. The function of the support rods 3 is to convert the tension of the tension cable 4 into a supporting force on the crossbeam 2, thereby enhancing the stability of the entire structure.
[0046] The tension cable 4 extends laterally and is located below the crossbeam 2, with its two ends fixed to the tops of the two columns 1 or directly connected to the two ends of the crossbeam 2. When subjected to external force, the tension cable 4 generates tension, which applies an upward reaction force through the support rod 3 to help the crossbeam 2 resist deformation.
[0047] It should be noted that the tension of the tension cable 4 is converted into an upward supporting force on the crossbeam 2 by the support rod 3, effectively relieving the pressure on the crossbeam 2 and preventing it from bending excessively. In this process, the support rod 3, the crossbeam 2, and the tension cable 4 work together to form a self-balancing system. When the external load increases, the tension of the tension cable 4 also increases, which in turn provides a greater reaction force to the crossbeam 2 through the support rod 3, ensuring that the crossbeam 2 maintains a relatively stable state.
[0048] In the technical solution of this utility model, when the crossbeam 2 is subjected to external forces such as vertical self-weight load, snow load and wind pressure and is about to deform, the tension cable 4 can quickly generate tension, and apply an upward reaction force to the crossbeam 2 through the support rod 3, so that the crossbeam 2 can effectively resist deformation. Through the internal tension, not only can the rigidity and stability of the overall structure be guaranteed, but the same load-bearing capacity can also be achieved while reducing the amount of material used, thereby achieving the purpose of reducing costs and improving the economy of the photovoltaic roof system 100.
[0049] Specifically, in this embodiment, the lower end of the support rod 3 is provided with a through hole (not shown) for the tension cable 4 to pass through.
[0050] The lower end of the support rod 3 is provided with one or more cable passage holes for the tension cable 4 to pass through. It is understood that the position, size, and number of these cable passage holes are precisely designed according to actual needs to ensure that both mechanical performance requirements are met and installation and adjustment are convenient.
[0051] The installation process of the tension cable 4 is as follows: First, before installing the support rods 3, the position of the support rods 3 in the truss structure 10 needs to be pre-positioned, determining the exact installation point of each support rod 3 and the path of the tension cable 4, and fixing the support rods 3 to the crossbeam 2. Next, the tension cable 4 is threaded through the wire holes at the lower ends of all support rods 3 according to the predetermined route. Ensure that the tension cable 4 passes smoothly through each wire hole and maintains appropriate slack for subsequent tensioning. After threading, the tension cable 4 is gradually tensioned until the designed tension value is reached.
[0052] It should be noted that during this process, the cable hole on the support rod 3 is used as an anchor point, and the stability of the entire system is optimized by adjusting the tension of the tension cable 4. Simultaneously, it is ensured that the upper and lower ends of the support rod 3 are tightly abutted against the crossbeam 2 and the tension cable 4, forming a stable self-balancing system.
[0053] Specifically, please refer to Figure 1 and Figure 3 In some embodiments, the two ends of the crossbeam 2 are fixedly connected to the upper ends of the two columns 1, and the two ends of the tension cable 4 are connected to the upper ends of the two columns 1.
[0054] The two ends of the crossbeam 2 are fixedly connected to the tops of the two columns 1 respectively, that is, a rigid connection is adopted, such as welding, bolting or other high-strength connection methods suitable for steel structures, to ensure that the connection between the crossbeam 2 and the columns 1 is both firm and reliable.
[0055] The installation process of the tension cable 4 is as follows: A specially designed anchoring structure is reserved or installed at the top of the column 1 to fix the end of the tension cable 4 to withstand the expected tension without slippage or damage. After the tension cable 4 is passed through the cable guide hole at the lower end of the plurality of support rods 3, its two ends are respectively fixed to the top of the corresponding column 1 through the anchoring structure. The initial tension of the tension cable 4 is adjusted according to the design requirements to ensure that it can provide the necessary support force for the entire structure.
[0056] This configuration, by directly fixing both ends of the crossbeam 2 to the column 1 and having the tension cable 4 originate from the top of the column 1, forms a tightly integrated structural system. This not only enhances the rigidity and stability of the structure but also effectively distributes the load and reduces local stress concentration.
[0057] Specifically, please refer to Figure 2In other embodiments, the two ends of the crossbeam 2 are hinged to the upper ends of the two columns 1, and the two ends of the tension cable 4 are connected to the two ends of the crossbeam 2 respectively.
[0058] The two ends of the beam 2 are connected to the top of the column 1 by hinges. The hinged design allows the beam 2 to rotate freely within a certain range, adapting to minor deformations caused by factors such as temperature changes and uneven load distribution, thereby reducing stress concentration inside the structure.
[0059] It should be noted that, in order to achieve the hinge, a hinge device is provided at the top of the column 1 to ensure that it can withstand the expected load and allow the crossbeam 2 to rotate freely in its plane.
[0060] The specific installation process is as follows: Precisely install the crossbeam 2 onto the hinge device and adjust it to ensure that the crossbeam 2 is horizontal and that the hinge point operates smoothly. Use high-strength bolts or other suitable fasteners to secure the hinge device in place, ensuring a firm and reliable connection.
[0061] The two ends of the tension cable 4 are directly connected to the two ends of the crossbeam 2. In this way, the tension cable 4 directly transmits tension to the crossbeam 2 through the multiple support rods 3, forming a self-balancing whole with the crossbeam 2, the multiple support rods 3, and the tension cable 4, thereby enhancing its ability to resist external loads.
[0062] Further, please refer to Figure 5 In some embodiments, the plurality of support rods 3 include a first diagonal brace 31 and a second diagonal brace 32 located on the outermost side in the lateral direction. The lower ends of the first diagonal brace 31 and the second diagonal brace 32 are both connected to the corresponding column 1. The tension cable 4 is also connected to the lower ends of the first diagonal brace 31 and the second diagonal brace 32.
[0063] The first diagonal brace 31 and the second diagonal brace 32 can enhance the lateral stability of the truss structure 10. In particular, when facing lateral loads such as wind pressure, the diagonal brace 31 can effectively resist lateral displacement and ensure the stability and reliability of the entire system.
[0064] By directly connecting the tension cable 4 to the lower ends of the first diagonal brace 31 and the second diagonal brace 32 and connecting it to the column 1, the force can be concentrated at the node and uniformly transmitted along the direction of the diagonal brace 31, rather than forming a bending moment that may cause structural damage. This effectively disperses the stress brought by the external load, reduces the risk of local stress concentration, and improves the safety and durability of the structure.
[0065] Please see Figure 3 and Figure 4In other embodiments, the crossbeam 2 includes two chord members 21 extending laterally and spaced apart in the vertical direction, and a plurality of web members 22 disposed between the two chord members 21. The web members 22 are connected between the two chord members 21, and the two ends of each chord member 21 are correspondingly connected to the upper ends of the two columns 1. The end of the tension cable 4 is also connected to the end of the chord member 21 located below.
[0066] In this embodiment, a double-chord member 21 is used, which is reinforced by the web members 22 to enhance the overall rigidity and load-bearing capacity of the crossbeam 2. Especially when facing large vertical loads (such as snow loads or self-weight), this structure can more effectively resist deformation and ensure the stability and reliability of the system.
[0067] By directly connecting the tension cable 4 to both ends of the lower chord 21 and then to the column 1, the force can be concentrated at the nodes and uniformly transmitted along the direction of the lower chord 21, rather than forming a bending moment that could cause structural damage. This also effectively disperses the stress from external loads, reduces the risk of localized stress concentration, and achieves effective force transmission and dispersion.
[0068] It should be noted that in the existing technology, in order to enable the photovoltaic roof system to meet the mechanical requirements, the commonly used chord rods are mostly made of hollow square tubes with a wall thickness of 2.0mm and a diameter of 100mm x 50mm, which results in a high cost.
[0069] Specifically, in this embodiment, the cross-section of the chord 21 is rectangular, with the length of its long side being L1 and the length of its short side being L2, where 80mm≤L1≤100mm and 40mm≤L2≤50mm.
[0070] The cross-section of the chord 21 is set as rectangular, with its long side dimension L1 and short side dimension L2 limited to between 80mm and 100mm and between 40mm and 50mm respectively, in order to balance structural performance and economy.
[0071] Specifically, L1 can be 100mm, 95mm, 90mm, 85mm, or 80mm, etc., and L2 can be 50mm, 48mm, 46mm, 45mm, 44mm, 42mm, or 40mm, etc. In this application, smaller hollow square tubes (e.g., 90mm x 45mm) can be used, while maintaining or appropriately adjusting the wall thickness to meet mechanical requirements. This not only avoids sacrificing structural safety and stability, ensuring sufficient load-bearing capacity and deformation resistance, but also reduces the amount of steel required per meter of chord 21, lowering the overall cost. Furthermore, it reduces the overall weight of the structure, facilitating transportation and installation, and further improving construction efficiency.
[0072] Specifically, in this embodiment, the cross-section of the column 1 is a square, the side length of the square is L, 80mm≤L≤150mm; and / or, the column 1 is set as a hollow tube, the wall thickness of the column 1 is W, 2mm≤W≤4mm.
[0073] It should be noted that traditionally, columns are mostly made of hollow square tubing with a diameter of 150mm x 150mm and a wall thickness of 4.0mm. However, in this invention, a smaller square cross-section (e.g., 90mm x 90mm or 120mm x 120mm) and a wall thickness of 2.0mm or 3.0mm can be used to meet mechanical requirements, thereby reducing the overall cost by reducing the amount of material used.
