[0035] This application proposes a support member 10.

[0036] Please see Figures 1 to 3 In one embodiment of this application, the support member 10 includes a support sleeve 100 and a support core 200. The support core 200 is installed inside the support sleeve 100. The extension direction of the support core 200 is parallel to the extension direction of the support sleeve 100. The support sleeve 100 is provided with a top abutment 110 at each end corresponding to the support core 200. The support core 200 is located between the two top abutments 110, and the end face of the support core 200 abuts against the corresponding top abutment 110.

[0037] Specifically, the support core 200, as an internal component, is the main part of the support member 10 that bears the axial pressure from the outside; the support sleeve 100, as an external component, has high tensile strength. The end face of the support core 200 abuts against the corresponding abutment top 110, so that the two end faces of the support core 200 and the two abutment tops 110 generate an interaction force. The forces F1 on the two abutment tops are opposite, and the forces F2 on the two ends of the support core are opposite. As a result, the support sleeve 100 is subjected to tensile force, and the support core 200 is subjected to compressive force. The tensile stress on the support sleeve 100 and the compressive stress on the support core 200 are balanced with each other, thus forming a prestressed self-balancing system. This makes the support member 10 form a stable structure with self-restraint. Even under the action of external force, the support core 200 will not easily shift laterally or bend, thereby improving the buckling resistance of the support core 200.

[0038] Understandably, even when the support core 200 is deformed or has a tendency to deform under the action of external force, when the outer peripheral structure of the support core 200 acts on the inner peripheral wall of the support sleeve 100, the tensile force on the support sleeve 100 keeps the support sleeve 100 in a taut state and makes it less prone to deformation. This, in turn, provides support to the support core 200 and applies a restoring force to the support core 200, reducing the risk of instability of the support member 10 and enhancing the stability of the support member 10.

[0039] Because the prestresses between the support sleeve 100 and the support core 200 are balanced, the support member 10 can significantly improve its buckling resistance without increasing the cross-sectional size or material thickness, thereby reducing the need for additional materials due to structural stability requirements and significantly improving material utilization. Compared with traditional designs that rely on large cross-sections and high-strength materials, the support member 10 proposed in this application can achieve the same or better structural stability with less material, thereby reducing the self-weight of the support member 10. This not only reduces material costs but also lowers construction difficulty and transportation costs, thus significantly improving the overall economic efficiency of the support member 10 and making its application more widespread.

[0040] In addition, the abutment 110 also serves as a limiting device. The support core 200 is located between the two abutments 110, and the end face of the support core 200 abuts against the corresponding abutment 110. The abutment 110 can clamp the support core 200 to lock the relative position between the support sleeve 100 and the support core 200, preventing slippage between the support sleeve 100 and the support core 200 during use.

[0041] The technical solution of this application introduces mutually balanced prestress by having the end face of the support core 200 abut against the top 110 of the corresponding support sleeve 100. This allows the support sleeve 100 and the support core 200 to bear tensile and compressive forces respectively during use, forming a stable structure with self-restraint. This effectively improves the stability and buckling resistance of the support member 10 and enhances the ultimate bearing capacity of the support member 10.

[0042] In one implementation, please refer to Figure 1 The support core 200 includes a main body section 210 and connecting sections 220 located at opposite ends of the main body section 210. The diameter of the connecting sections 220 is larger than that of the main body section 210. The two connecting sections 220 are respectively connected to the corresponding top abutment 110.

[0043] The main body section 210 is the primary load-bearing component of the support core 200. Connecting sections 220 are located at both ends of the main body section 210. The support sleeve 100 and the support core 200 are connected to the abutment top 110 via the connecting sections 220. The diameter of the connecting section 220 is larger than that of the main body section to increase the contact area between the connecting section 220 and the abutment top 110, thereby improving the reliability of the connection between them. This allows for the smooth transfer of tensile stress on the support sleeve 100 and compressive stress on the support core 200, forming a balanced prestress. Simultaneously, the larger diameter of the connecting section 220 allows for more effective transfer of external loads, reducing localized stress concentration.

[0044] After introducing mutually balanced prestresses into the support member 10, its stability, buckling resistance, and ultimate bearing capacity are all improved. This reduces the need for additional material in the main body section 210 due to structural stability requirements, allowing for optimization of the diameter of the main body section 210 and significantly improving its material utilization rate. The smaller diameter of the main body section 210 facilitates the insertion of the support core 200 into the support sleeve 100 and reduces the material usage of the support core 200, thus lowering costs.

[0045] In other embodiments, the diameter of the connecting segment 220 may be approximately the same as the diameter of the main body segment 210.

[0046] In one implementation, please refer to Figure 1 The outer periphery of the connecting section 220 abuts against the inner peripheral wall of the support sleeve 100.

[0047] The outer periphery of the connecting section 220 abuts against the inner peripheral wall of the support sleeve 100, so that the connecting section 220 can be tightly installed in the support sleeve 100. The connecting section 220 is subjected not only to the pressure from the top 110 in the axial direction of the support core 200, but also to the support force from the inner peripheral wall of the support sleeve 100 in the radial direction of the support core 200. As a result, the connecting section 220 is not easy to be displaced or rotated in the support sleeve 100, which further improves the stability and buckling resistance of the support member 10.

[0048] In other embodiments, the outer periphery of the connecting section 220 may also be clearance-fitted with the inner peripheral wall of the support sleeve 100.

[0049] In one implementation, please refer to Figure 1 The side of the connecting section 220 facing the main body section 210 is inclined toward the axis of the support core 200 in the direction from the connecting section 220 to the main body section 210.

[0050] The side of the connecting segment 220 facing the main body segment 210 is tapered, gradually transitioning from the connecting segment 220 to the main body segment 210, causing the diameter of the connecting segment 220 to gradually decrease until it is the same as the diameter of the main body segment 210. This tapered transition of the side of the connecting segment 220 facing the main body segment 210 serves as a guide. During the process of inserting the support core 200 into the support sleeve 100, the side of the connecting segment 220 facing the main body segment 210 can guide the top 110 to move along the inclined surface to the other side of the connecting segment 220 away from the main body segment 210, thereby improving the ease of inserting the connecting segment 220 into the support sleeve 100. Furthermore, through the tapered transition, the stress between the connecting section 220 and the main body section 210 can be distributed more evenly, avoiding stress concentration caused by abrupt changes, thereby improving the fatigue resistance of the support core 200 structure and reducing the risk of structural instability caused by local stress concentration, thus improving the buckling resistance of the support member 10; at the same time, the tapered transition can improve the connection strength between the connecting section 220 and the main body section 210, thereby improving the load-bearing capacity of the entire support core 200.

[0051] In one implementation, please refer to Figure 1 The support core 200 has at least one abutting part 230 protruding between its two ends, and the outer periphery of the abutting part 230 abuts against the inner peripheral wall of the support sleeve 100.

[0052] The outer periphery of the abutment portion 230 abuts against the inner peripheral wall of the support sleeve 100, effectively increasing the contact area between the support core 200 and the support sleeve 100 during compression, thereby enhancing the self-aligning effect of the support member 10. When the support core 200 tends to deform, the abutment portion 230 acts on the inner peripheral wall of the support sleeve 100. Due to the tensile force on the support sleeve 100, it remains taut and less prone to deformation. Conversely, the abutment portion 230 provides support to the support core 200 and applies a self-aligning force. The support core 200 automatically self-aligns through the abutment portion 230, further improving the overall stability and buckling resistance of the support member 10. The support member 10 can be designed with lighter materials and smaller cross-sectional dimensions, thus achieving a lightweight overall structure. The reduced weight of the support member 10 not only lowers the construction and transportation costs of the subsequent photovoltaic bracket but also provides greater convenience for subsequent assembly and installation.

[0053] Furthermore, the abutment portion 230 abuts against the inner circumferential wall of the support sleeve 100 along the circumferential direction of the support core 200. Regardless of which direction the support core 200 tends to become unstable, the support sleeve 100 can apply a restoring force to the support core 200 through the abutment portion 230 due to the pre-applied tension, thereby reducing the risk of instability and enhancing the stability of the support member 10.

[0054] In one implementation, please refer to Figure 1Multiple abutment portions 230 are provided, and the multiple abutment portions 230 are spaced apart along the axial direction of the support core 200.

[0055] Multiple abutment portions 230 help resist buckling caused by external loads. Under multi-point constraints, multiple abutment portions 230 can provide more support points, making it more difficult for the support core 200 to undergo overall or local lateral displacement, thereby improving the buckling resistance of the support member 10. The distribution of the abutment portions 230 can be adjusted according to specific application scenarios. For longer support members 10, the number of abutment portions 230 can be increased or the spacing between two adjacent abutment portions 230 can be adjusted to adapt to different stress requirements.

[0056] In other embodiments, for shorter support members 10, only one abutment portion 230 may be provided, which is located near the middle of the support core 200.

[0057] In one implementation, please refer to Figure 1 The two sides of the abutment portion 230 in its axial direction gradually approach each other in the direction extending radially outward along the abutment portion 230.

[0058] From the axis of the support core 200 outwards, the thickness of the abutment portion 230 gradually decreases along the axial direction of the support core 200. The end of the abutment portion 230 connecting to the support core 200 has a larger thickness, resulting in a stronger connection and reducing the risk of breakage. The end of the abutment portion 230 abutting against the support sleeve 100 has a smaller thickness, resulting in less friction between the abutment portion 230 and the inner wall of the support sleeve 100, making installation of the support core 200 easier. The inclined design of the two sides of the abutment portion 230 along its axial direction also serves a guiding function. During the insertion of the support core 200 into the support sleeve 100, the inclined sides of the abutment portion 230 can guide the abutment top 110 to move along the inclined surface, facilitating the insertion of the abutment portion 230 into the support sleeve 100. The cross-section of the abutment portion 230 along the axial direction of the support core 200 is approximately conical or arc-shaped.

[0059] In one implementation, please refer to Figure 3 At least one abutment 110 has an installation opening 120, and the installation opening 120 is provided with a guide slope 130, which is used to guide the support core 200 from the installation opening 120 into the support sleeve 100.

[0060] Both abutment portions 230 may form mounting openings 120; alternatively, one abutment portion 230 may have a mounting opening 120 while the other abutment portion 230 may not, meaning one end of the support sleeve 100 is a closed structure. The guide ramp 130 guides the support core 200 into the support sleeve 100 through the mounting opening 120. The guide ramp 130 can cooperate with the inclined sides of the connecting section 220 and the abutment portion 230 respectively, guiding the connecting section 220 and the abutment portion 230 smoothly through the mounting opening 120, improving the ease of installation of the support core 200. Simultaneously, it also reduces wear on the edges of the mounting opening 120 caused by the connecting section 220 and the abutment portion 230.

[0061] In one embodiment, one end of the support sleeve 100 is provided with a threaded portion 140, which is used to connect with the extrusion equipment so that the extrusion equipment can insert the support core 200 into the support sleeve 100.

[0062] Please see Figure 3 and Figure 5 ,in, Figure 5 (a) is a schematic diagram of the structure of the support sleeve 100 and the support core 200 before assembly. Figure 5 Figure (b) shows a schematic diagram of the structure after the support sleeve 100 and the support core 200 are assembled. Specifically, the longer support core 200 is inserted into the shorter support sleeve 100 for initial assembly, at which point the lengths of the support sleeve 100 and the support core 200 differ. The extrusion equipment includes a connecting device and an extrusion device. The connecting device is connected to the support sleeve 100 through a threaded portion 140 at the end of the support sleeve 100. The extrusion device abuts against the end face of the support core 200 and extrudes the support core 200, shortening it by d1. Simultaneously, the support sleeve 100 is stretched by d2 until the lengths of the support sleeve 100 and the support core 200 are the same. During this process, the support core 200 is subjected to pressure, while the support sleeve 100 is subjected to tension. Since the tensile stress of the support sleeve 100 and the compressive stress of the support core 200 are balanced, the support member 10 forms a prestressed self-balancing system. During use, the support sleeve 100 is subjected to tensile force. Its deformation characteristics enable the support sleeve 100 to provide effective support when the support core 200 is under pressure and becomes unstable, thereby improving the buckling resistance and stability of the support member 10. The threaded portion 140 can be provided on the outer peripheral wall of the support sleeve 100 or on the end face of the support sleeve 100.

[0063] In one embodiment, the support sleeve 100 is made of metal, and the support core 200 is made of concrete.

[0064] The support sleeve 100 and the support core 200 can be made of different materials to optimize the combined performance. For example, the support sleeve 100 can be made of materials with higher tensile strength, such as steel or aluminum alloys. The support core 200 can be made of materials with higher compressive strength and lower cost, such as concrete.

[0065] In other embodiments, the support sleeve 100 and the support core 200 may also be selected from composite materials such as glass fiber reinforced plastic (GFRP) and carbon fiber reinforced plastic (CFRP) depending on factors such as the required load-bearing capacity, environmental conditions (such as corrosivity), and cost budget.

[0066] In one embodiment, the outer peripheral wall of the support sleeve 100 is provided with reinforcing ribs and / or a covering layer.

[0067] Where higher tensile strength is required, reinforcing ribs can be provided on the outer peripheral wall of the support sleeve 100, and / or the support sleeve 100 can be covered with composite materials to enhance the tensile strength of the support sleeve 100. The reinforcing ribs can extend along the axis of the support sleeve 100, extend along the circumference of the support sleeve 100, or be arranged in a crisscross pattern on the outer peripheral wall, etc.

[0068] In one implementation, please refer to Figure 6 The support sleeve 100 includes a sleeve body 150 and an adjustment part 160 disposed at at least one end of the sleeve body 150. The top 110 is disposed on the adjustment part 160, and the adjustment part 160 is used to adjust the length of the support sleeve 100.

[0069] By providing the adjustment part 160, the length of the support sleeve 100 can be finely adjusted on-site according to actual needs, thereby improving adaptability. The adjustment part 160 can be provided at one end of the sleeve body 150; or the adjustment part 160 can be provided at both ends of the sleeve body 150, thereby improving the flexibility and convenience of length adjustment of the support sleeve 100.

[0070] In one implementation, please refer to Figure 6 The adjusting part 160 can slide relative to one of the inner and outer peripheral walls of the sleeve body 150 along the axial direction of the sleeve body 150. A groove is formed on the inner peripheral wall of the sleeve body 150, and the adjusting part 160 is disposed within the groove. The adjusting part 160 is connected to the sleeve body 150 via an adjusting bolt. The sleeve body 150 has an adjusting screw hole, the screw of which is screwed into the adjusting screw hole, and the nut of the adjusting bolt abuts against the adjusting part 160, so that the relative position between the adjusting part 160 and the sleeve body 150 is adjustable, thereby adjusting the length of the supporting sleeve 100.

[0071] In another embodiment, one of the inner and outer peripheral walls of the sleeve body 150 is threadedly connected to the adjustment part 160. The relative position of the sleeve body 150 and the adjustment part 160 is adjusted by the length of the threaded connection between the two, thereby adjusting the length of the support sleeve 100.

[0072] In one implementation, please refer to Figure 4 The support core 200 includes multiple support segments 240 in its axial direction. Two adjacent support segments 240 are welded or locked by fasteners. The end faces of the support segments 240 located at both ends in the axial direction of the support core 200 abut against the corresponding abutment tops 110.

[0073] The support core 200 is designed as a multi-segment connection, with adjacent support segments 240 spliced ​​together by bolts or welding, flexibly adapting to different working conditions according to specific construction needs. Each support segment 240 includes a main body and two end portions located at both ends of the main body, with the diameter of the end portions being larger than the diameter of the main body. The support core 200 is formed by connecting multiple independent support segments 240. The end faces of the end portions of the support segments 240 located at both ends of the support core 200 in the axial direction abut against corresponding abutment tops 110. The two abutting ends of two adjacent support segments 240 located at both ends of the support core 200 in the axial direction form the abutment portion 230 of the support core 200. Each support segment 240 can be manufactured and tested individually, and then assembled into a complete support core 200 on-site or in the factory, thereby improving manufacturing and installation efficiency. Furthermore, multiple independent support segments 240 are easier to transport and store than a single long segment. If a single support segment 240 is damaged or needs replacement, the affected part can be directly disassembled for repair or replacement without replacing the entire support core 200. Adjacent support sections 240 can be connected together by welding or fasteners (such as bolts). Welded connections provide greater strength, while fastener connections offer better disassembly and ease of maintenance.

[0074] In other embodiments, the support core 200 may also be integrally formed.

[0075] The support member 10 proposed in this application exhibits excellent buckling resistance and significantly improved ultimate bearing capacity under conventional axial compression conditions. Under eccentric compression or large lateral forces, the combination of the abutment portion 230 and the support sleeve 100 still provides effective support and centering, reducing the risk of lateral instability of the support core 200. Under compression-bending stress conditions, the support sleeve 100 can withstand a stress state of compression on one side and tension on the other, at which point the bending stress on the support core 200 is relatively small. The support member 10 can be used as a diagonal brace or column, etc., as a supporting structure.
