Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a support frame structure for a photovoltaic support. Background Technology
[0002] In photovoltaic support systems, the central support structure plays a crucial role. It not only needs to bear the weight of the photovoltaic modules, but also ensure the stability of the entire system under various climatic conditions.
[0003] Traditional photovoltaic (PV) mounting systems typically construct their central support structure by drilling holes or openings in several profiles (1') and then connecting them with bolts. However, this method has several drawbacks. First, the precision required for drilling or opening on-site is extremely high; any deviation will directly affect the stability and safety of the entire support structure. Second, the construction process is complex and time-consuming, increasing both installation costs and the construction period. Furthermore, it demands a high level of professional skill from construction workers, requiring extensive training to become competent, further increasing labor costs. Utility Model Content
[0004] The purpose of this utility model is to provide a support frame structure for photovoltaic brackets that is easy to assemble and has high structural stability.
[0005] To achieve the above objectives, the solution of this utility model is as follows: a support frame structure for a photovoltaic bracket, including columns, horizontal tie beams and diagonal braces. The columns are vertically supported between the roof and the ground of the photovoltaic bracket, the horizontal tie beams are horizontally erected on the columns, and the diagonal braces are inclinedly erected between the columns and the horizontal tie beams, forming a triangular structure.
[0006] Profiles used as columns and tie beams have T-shaped grooves on the outer periphery of their main body;
[0007] All profiles are secured at their joints by clamping assemblies. The clamping assemblies have mounting holes for T-bolts to pass through. The T-bolts are used to fix the profiles together by engaging with the grooves on the profiles and the mounting holes on the clamping assemblies.
[0008] Furthermore, the groove of the profile is connected to the main body in a zigzag shape.
[0009] Furthermore, the zigzag structure includes a horizontal plate and two vertical plates, with the first and second vertical plates located at both ends of the horizontal plate and extending parallel to each other in the same direction from both ends of the horizontal plate.
[0010] Furthermore, the clamp assembly connecting the column and the crossbeam is a first clamp assembly. The first clamp assembly includes a Z-shaped clamp, the middle of which is a clamping part used to clamp the crossbeam, and the two sides of which are mounting parts. The mounting parts are parallel to the surface of the column and have racetrack-shaped mounting holes that mate with T-bolts.
[0011] Furthermore, the clamp assembly connecting the column and the diagonal brace is a second clamp assembly. The second clamp assembly includes a straight clamp with several racetrack-shaped mounting holes that mate with T-bolts.
[0012] Furthermore, the clamp assembly connecting the diagonal brace and the horizontal tie beam is a third clamp assembly. The third clamp assembly includes an L-shaped clamp and a U-shaped clamp. The upper end of the L-shaped clamp has a racetrack-shaped mounting hole, and the lower end has a circular mounting hole. The upper middle part of the U-shaped clamp has a racetrack-shaped mounting hole, and the lower part has a circular mounting hole.
[0013] Furthermore, the T-bolt includes a head and a shank. The head is a parallelepiped, with one set of parallel sides being the long side and the other two sets being the short sides.
[0014] Furthermore, the groove on the profile extends along the length of the main body, and the groove has lateral openings on both sides.
[0015] Furthermore, the cross-section of the main body of the profile is quadrilateral, pentagonal, hexagonal, or octagonal.
[0016] Furthermore, the profile is a hollow structure.
[0017] After adopting the above solution, the beneficial effects of this utility model are as follows:
[0018] Firstly, by using profiles with T-grooves and clamp components connected with T-bolts, the conventional drilling / opening operations are eliminated. During assembly, only tightening the T-bolts is required for rapid assembly, greatly simplifying the construction process, shortening installation time, and thus reducing installation costs. Using profiles with grooves also reduces the risk of structural instability caused by drilling holes in the profiles.
[0019] Secondly, this connection method not only improves construction efficiency, but also reduces the professional skills required of construction workers. Workers only need simple training on the installation positions of components to be able to start working, further reducing labor costs.
[0020] In addition, the triangular structure formed by the columns, horizontal braces and diagonal braces enhances the stability of the entire support system, improves its resistance to wind and snow pressure, and ensures the safe operation of photovoltaic modules under various climatic conditions.
[0021] In summary, the photovoltaic bracket support frame structure of this utility model has the advantages of simple structure, convenient installation, low cost, and high stability, and has broad application prospects. Attached Figure Description

[0040] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0041] This utility model provides a support frame structure for a photovoltaic bracket, such as... Figures 2 to 12 As shown, the system includes a column 1, a horizontal tie beam 2, and a diagonal brace 3. The column 1 is vertically supported between the roof and the ground of the photovoltaic system, playing a crucial supporting role; the horizontal tie beam 2 is horizontally erected on the column 1 to enhance the horizontal stability of the system; the diagonal brace 3 is inclined between the column 1 and the horizontal tie beam 2, and the three together form a stable triangular structure.
[0042] In this design, the profile 4 used as the column 1 and the tie beam 2 typically has a hollow main body 41, but this design is not an absolute requirement. It can be flexibly adjusted according to actual application needs. The main advantage of using a hollow main body 41 structure is that it significantly reduces the overall weight, thereby improving the handling and installation efficiency of the photovoltaic bracket. Simultaneously, the hollow design effectively improves material utilization, reduces costs, and makes the manufacturing of the photovoltaic bracket more economical and efficient. Furthermore, the hollow structure provides greater flexibility for the profile 4, facilitating plug-in assembly with components such as the base and connectors.
[0043] like Figure 5 As shown, the outer periphery of the main body 41 of the profile 4 has a T-shaped groove 42. The groove 42 on the profile 4 extends along the length of the main body 41, and both sides of the groove 42 have lateral slots for the head of the T-bolt 8 to enter. The structure of a T-bolt used in this case is as follows: Figure 8 and Figure 11 As shown, it includes a head and a screw. The head is a parallelogram, with one set of parallel sides being the long sides and the other two sets being the short sides.
[0044] The fit between the T-bolt 8 and the groove 42 of the profile 4 is as follows: During installation, refer to... Figure 6 and Figure 8 First, slide the head of the T-bolt 8 into the side groove of the recess 42, then rotate it at a certain angle so that its head is locked in the groove 42. Next, use the flange nut 9 or other type of nut 9 to tighten the T-bolt 8, thereby achieving a fixed connection with the profile 4.
[0045] As a further improvement to the structure, the connection between the groove 42 of the profile 4 and the main body 41 is a Z-shaped structure 43 bent connection. Specifically, as... Figures 5 to 7 As shown, the Z-shaped structure 43 includes a horizontal plate 431 and two vertical plates. The first vertical plate 432 and the second vertical plate 433 are located at both ends of the horizontal plate 431 and extend parallel to each other in the same direction from both ends of the horizontal plate 431. During processing, these components are integrally formed with the main body 41. Compared with traditional sharp bending angles, this Z-shaped transition structure can effectively disperse stress and significantly reduce stress concentration, thus making the stress distribution at the connection more uniform and reasonable. This design not only significantly improves the fatigue resistance of the profile 4 during use and enhances the structural stability, but also greatly improves the overall load-bearing capacity and reliability of the photovoltaic support profile 4, providing a guarantee for the safe and efficient operation of the photovoltaic support.
[0046] Different types of clamp assemblies are used as connectors at the joints of each profile 4, and the connection and fixation are achieved by the cooperation of T-bolts 8 and grooves 42 on the profile 4. For example... Figures 9 to 11 As shown, the clamp assembly has mounting holes for T-bolts 8 to pass through. The T-bolts 8, by engaging with the grooves 42 on the profiles 4 and the mounting holes on the clamp assembly, securely connect the profiles 4. The types of clamp assemblies used in this solution include, but are not limited to, those described below:
[0047] like Figure 9 As shown, the clamp assembly connecting the column 1 and the crossbeam 2 is the first clamp assembly 5. The first clamp assembly 5 includes a Z-shaped clamp. The middle part of the Z-shaped clamp is the clamping part, which is used to clamp the crossbeam 2. The two sides of the Z-shaped clamp are the mounting parts. The mounting parts are parallel to the surface of the column 1 and have racetrack-shaped mounting holes 10 that mate with T-bolts 8.
[0048] like Figure 10 As shown, the clamp assembly connecting the column 1 and the diagonal brace 3 is the second clamp assembly 6. The second clamp assembly 6 includes a straight clamp with several racetrack-shaped mounting holes 10 that mate with T-bolts 8.
[0049] like Figure 11 As shown, the clamp assembly connecting the diagonal brace 3 and the horizontal tie beam 2 is the third clamp assembly 7, which includes an L-shaped clamp and a U-shaped clamp. The L-shaped clamp has a racetrack-shaped mounting hole 10 at its upper end and a circular mounting hole 11 at its lower end; the U-shaped clamp has a racetrack-shaped mounting hole 10 in its upper middle part and a circular mounting hole 11 at its lower part. The upper ends of the L-shaped and U-shaped clamps clamp the horizontal tie beam 2, and their lower ends are locked to the diagonal brace 3 by T-bolts 8 and nuts 9.
[0050] Regarding the cross-sectional shape of profile 4 (body 41), this solution offers a variety of designs, including but not limited to quadrilateral, pentagonal, hexagonal, and octagonal options, such as... Figure 12 As shown, the selection of these shapes is entirely based on actual assembly requirements and application scenarios. This solution does not impose specific limitations on them to ensure maximum flexibility and adaptability.
[0051] Similarly, the number of grooves 42 distributed around the outer periphery of profile 4 may include, but is not limited to, two, three, or four grooves 42. The specific number depends on assembly requirements and application scenarios. Figure 12 As shown. This solution does not impose a rigid requirement on the number of grooves 42, but can meet the personalized configuration needs of different photovoltaic support systems.
[0052] The installation process of the photovoltaic bracket support frame structure of this utility model is as follows:
[0053] First, cut profiles of appropriate length 4 according to the construction drawings to serve as columns 1 and horizontal tie beams 2. At the same time, select angle steel with an L-shaped cross section as diagonal bracing 3.
[0054] Next, install column 1: fix column 1 vertically. Column 1 is usually fixed to the base, but it can also be fixed directly to the ground. The specific installation method is not limited in this case, so as to adapt to the needs of different scenarios.
[0055] Next is the installation of the tie beam 2: using the first clamp assembly 5 and the provided T-bolts 8 and nuts 9, the column 1 is fixed to the tie beam 2.
[0056] Finally, install the diagonal brace 3: Based on the first clamp assembly 5 already fixed in the installation steps of the tie beam 2, measure down approximately 500-600mm and directly fix the second clamp assembly 6 at this position. Then, fix one end of the diagonal brace 3 to the second clamp assembly 6. According to the length of the diagonal brace 3, use fasteners (T-bolts 8 and nuts 9) to fix the third clamp assembly 7 in the groove 42 of the tie beam 2. Then, fix the other end of the diagonal brace 3 to the lower end of the third clamp assembly 7, thus completing the installation of the entire diagonal brace 3.
[0057] The photovoltaic support frame structure of this utility model only requires the corresponding assembly of connectors, T-bolts, and other accessories during installation, eliminating the need for cumbersome drilling operations. This not only greatly improves installation efficiency and reduces installation costs but also effectively avoids structural damage and safety hazards that may result from drilling. Simultaneously, this assembly method enhances the stability and overall load-bearing capacity of the photovoltaic support structure, ensuring the safety and reliability of the photovoltaic support during long-term use.
