Secondly, welding construction is difficult, there are many welding points, and the complexity of the welding method makes the construction process cumbersome, increases labor costs, and affects the construction period. [Utility Model Content]

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an assembled photovoltaic bracket, which solves the problems of difficult construction and difficult quality control in the existing node welding connection method in the photovoltaic bracket, improves the controllability of the node quality, and thus ensures the stability of the overall performance of the bracket.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] An assembled photovoltaic bracket includes a first component and a second component connected to the first component, wherein the first component and the second component are provided with a connecting sleeve at the connecting position, the connecting sleeve is provided with a connecting hole, the connecting position of the first component and the second component is provided with a fixing hole, a fastener passes through the connecting hole and is connected to the fixing hole, and the connecting sleeves on the first component and the second component are welded and fixed together.

[0006] Preferably, the first component and the second component are both square tubes, and the connecting sleeve is a square tube.

[0007] Preferably, the fastener is a through bolt or a single-side bolt or a rivet.

[0008] Preferably, the rivet is formed by riveting the connecting holes.

[0009] Preferably, the inner wall of the connecting sleeve is provided with a protective layer; and / or the connecting sleeve is made of stainless steel or aluminum alloy.

[0010] Preferably, the protective layer is made of polytetrafluoroethylene material.

[0014] Preferably, the photovoltaic support is provided with purlins, and the purlins are formed by splicing at least two single-section purlins, and a connecting sleeve is inserted between two adjacent single-section purlins.

[0015] The utility model adopts the above technical solution and has the following beneficial effects:

[0016] 1. On site, first insert the connecting sleeves to be used into the components respectively, then slide the connecting sleeves along the components and adjust them to the corresponding positions. Before sliding the connecting sleeves to the connecting parts, determine the punching positions of the connecting parts on the components and punch the fixing holes. Then slide the connecting sleeves to the connecting parts and use fasteners to fix the connecting holes and the fixing holes. Finally, fix the connecting sleeves of the two connected components together.

[0017] The connection between the connecting sleeve and the component can be completed on the ground first, and then the connecting sleeves of the two connected components can be fixed together during the process of erecting the bracket, or the overall installation can be completed on the ground.

[0018] The above-mentioned assembled connection node uses a connecting sleeve to connect the two components, and uses fasteners to fix the connecting hole and the fixing hole. The connecting sleeves of the two connected components are fixed together in a conventional fixing method, which improves the controllability of the node quality and ensures the reliability and stability of the assembled connection. Due to the simple installation process, the construction difficulty is reduced and the construction efficiency is improved.

[0019] In addition, since the connecting sleeves on the first component and the second component are welded and fixed, there is no need to add a fastening structure on the connecting sleeve, and no fasteners are required, which facilitates construction and reduces costs. Of course, since the two components are not directly welded, damage to the coating of the components is avoided, and the connecting sleeve is a customized part. In order to facilitate welding and fixing between the connecting sleeves, a structure that is easy to weld can be pre-set, thereby facilitating welding and fixing between the connecting sleeves on the first component and the second component, reducing difficulty, facilitating quality control, and improving the controllability of node quality, thereby ensuring the stability of the overall performance of the bracket.

[0020] 2. The connecting sleeve is a square tube corresponding to the first component and the second component, which facilitates the connection and fixation between the connecting sleeve and the components.

The use of rivets is simple. You only need to use special equipment to tighten the rivet rod to complete the connection. It is easier to use than other connection methods and does not require professional skills.

[0022] 4. Since the inner wall of the connecting sleeve is provided with a protective layer, it ensures that the coating of the component is not damaged during the connection process, enhances the anti-corrosion performance and prolongs the service life. At the same time, the connecting sleeve is made of stainless steel or aluminum alloy to avoid rust on the connecting sleeve itself.

[0023] 5. Polytetrafluoroethylene has excellent heat and cold resistance and can be used for a long time at -180 to 260°C. At the same time, polytetrafluoroethylene has the advantage of an extremely low friction coefficient, so it can be used as a lubricant to facilitate the adjustment of the position of the connecting sleeve on the component.

[0024] 6. The protective layer can be a polytetrafluoroethylene coating, which is convenient for construction and reduces costs.

[0025] 7. The connection nodes of the utility model can be used in multiple locations on the photovoltaic support, such as the connection between the diagonal beam and the horizontal beam, and the connection between the column and the longitudinal beam. It has a wide range of applicability and can speed up the installation efficiency of the photovoltaic support.

[0026] 8. A connecting sleeve is inserted between two adjacent single-section purlins, thereby ensuring the reliability and stability of the connection, reducing the construction difficulty and improving the construction efficiency.

[0041] Embodiment 1

[0042] Reference Figures 1 to 3As shown, an assembled photovoltaic support comprises a first component and a second component, and an assembled connection node is provided between the first component and the second component. The first component and the second component are provided with a connecting sleeve 100 on the outer surface of the connecting portion, and the connecting sleeve 100 is provided with a connecting hole, and the connecting portion of the first component and the second component is provided with a fixing hole, and a fastener is provided between the connecting hole and the fixing hole, and the connecting sleeves on the first component and the second component are fixed together.

[0043] In the above technical solution, the connecting sleeves to be used are first inserted into the components on site, and then the connecting sleeves are slid along the components and adjusted to the corresponding positions. Before sliding the connecting sleeves to the connecting parts, the punching positions of the connecting parts on the components are determined, and the fixing holes are punched. Then the connecting sleeves are slid to the connecting parts, and the connecting holes and the fixing holes are fixed with fasteners. Finally, the connecting sleeves of the two connected components are fixed together.

[0044] The connection between the connecting sleeve and the component can be completed on the ground first, and then the connecting sleeves of the two connected components can be fixed together during the process of erecting the bracket, or the overall installation can be completed on the ground.

[0045] The above-mentioned assembled connection node uses a connecting sleeve to connect the two components, and uses fasteners to fix the connecting hole and the fixing hole. The connecting sleeves of the two connected components are fixed together in a conventional fixing method, which improves the controllability of the node quality and ensures the reliability and stability of the assembled connection. Due to the simple installation process, the construction difficulty is reduced and the construction efficiency is improved.

[0046] In this embodiment, the connecting sleeves on the first component and the second component are welded and fixed. There is no need to add a fastening structure on the connecting sleeve, and no fasteners are required, which facilitates construction and reduces costs. Of course, since the two components are not directly welded, damage to the coating of the components is avoided, and the connecting sleeve is a customized part. In order to facilitate welding and fixing between the connecting sleeves, a structure that is convenient for welding can be pre-set, thereby facilitating welding and fixing between the connecting sleeves on the first component and the second component, reducing difficulty, facilitating quality control, and improving the controllability of node quality, thereby ensuring the stability of the overall performance of the bracket.

[0047] Specifically, the fastener is a through bolt or a single-sided bolt or a rivet 101. In this embodiment, rivets are preferred, and the rivets are rivet rivets formed by riveting the connection holes. Rivet rivets have good load-bearing capacity and durability, and can ensure that the connection is not prone to loosening, breaking and other problems. The use of rivets is simple, and only special equipment is needed to tighten the rivet rod to complete the connection. It is easier to use than other connection methods and does not require professional skills. In addition, the connecting sleeve is provided with rivets 101 on at least two opposite sides to ensure the reliability of the connection. Of course, it is understandable that rivets can also be provided on three or four sides of the connecting sleeve.

[0048] A common photovoltaic support includes a column 11, an inclined beam 12 and a cross beam 13, wherein the inclined beam is connected to the column, and the cross beam is cross-fixed with the inclined beam. The above-mentioned assembled connection nodes are applicable to the inclined beams and the columns, and the cross beams and the inclined beams, that is, the first component is the column 11, and the second component is the inclined beam 12; or, the first component is the cross beam 13, and the second component is the inclined beam 12. Since the above-mentioned assembled connection nodes can be set between the column and the inclined beam, and between the inclined beam and the cross beam, it has a wide range of applicability and can improve the installation efficiency of the photovoltaic support.

[0049] The above-mentioned upright column 11, inclined beam 12 and cross beam 13 are preferably square tubes, such as galvanized square steel tubes, which are cheaper than aluminum alloy materials. Correspondingly, the connecting sleeve 100 is a square tube, such as a galvanized square steel tube. Since it is common with the component materials and the required length is short, it can be made of the scraps of the component manufacturing to reduce the cost.

[0050] Of course, it can be understood that the application scope of the above-mentioned assembled connection nodes is not limited to the above-mentioned examples. Figure 4 As shown, for the structure in which the lower end of the inclined beam is connected to the gutter joist 14, the above-mentioned assembled connection node is set between the lower end of the inclined beam and the gutter joist 14. The inclined beam and the gutter joist are both square tubes, but of different sizes. The side-by-side parts of the gutter joist and the inclined beam are both connected with a connecting sleeve 100 as the connecting part.

[0051] The connecting sleeve 100 is fixed to the lower end of the inclined beam and the gutter joist by rivets, and the rivets are formed by riveting the connecting holes. Two opposite sides of the connecting sleeve are correspondingly provided with rivets.

[0052] Embodiment 2

[0053] Photovoltaic components are used outdoors for a long time, and the surface is usually coated. When the connecting sleeve is connected to the component, it needs to slide along the component and adjust to the connection position to avoid damaging the coating during the connection process. Figure 2 As shown, a protective layer 102 is provided on the inner wall of the connecting sleeve 100 .

[0054] In this embodiment, the connecting sleeve 100 is made of stainless steel or aluminum alloy, and the protective layer 102 is made of polytetrafluoroethylene. Since the inner wall of the connecting sleeve is provided with a protective layer, it is ensured that the coating of the component is not damaged during the connection process, the anti-corrosion performance is enhanced, and the service life is increased. At the same time, the connecting sleeve is made of stainless steel or aluminum alloy to avoid rust on the connecting sleeve itself. Polytetrafluoroethylene has excellent heat and cold resistance and can be used for a long time at -180 to 260°C. At the same time, polytetrafluoroethylene has the advantage of an extremely low friction coefficient, so it can be used as a lubricant to facilitate the adjustment of the position of the connecting sleeve on the component.

[0055] Specifically, the protective layer 102 is a polytetrafluoroethylene coating or a polytetrafluoroethylene gasket. The protective layer can be a polytetrafluoroethylene coating, which is convenient for construction and reduces costs.

[0056] Embodiment 3

[0057] Usually photovoltaic brackets are equipped with purlins, such as Figure 5 As shown, the purlin is formed by splicing at least two single-section purlins 200 , and a connecting sleeve 100 is inserted between two adjacent single-section purlins 200 .

[0058] Referring to the first and second embodiments, the two single-section purlins 200 are both square tubes, the connecting sleeve 100 is also a square tube, the connecting sleeve 100 and the two single-section purlins 200 are fixed with rivets, and the rivets are formed by riveting the connecting holes, and the two opposite sides of the connecting sleeve are correspondingly provided with rivets. Thus, the reliability and stability of the connection are ensured, the construction difficulty is reduced, and the construction efficiency is improved.

[0059] It is understandable that rivets may also be provided on three or four sides of the connecting sleeve.

[0060] It can be understood that the purlins can be the diagonal beams and cross beams in the first and second embodiments.

[0061] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
