[0007] The purlin bracket has a first side plate and a second side plate that are bent and connected. The purlin bracket has a reinforcing rib stamped at least at the connection between the first side plate and the second side plate. The first side plate abuts against the purlin and the second side plate abuts against the inclined beam.

[0008] According to the mounting bracket of this application, by setting the purlin structure, there are a first side plate and a second side plate that are bent and connected, and a reinforcing rib is stamped at least at the connection between the first side plate and the second side plate.

[0009] According to one embodiment of this application, the purlin bracket has a first flange extending from one end of the first side plate away from the second side plate to one end of the second side plate away from the first side plate.

[0010] According to the mounting bracket of this application, by providing a first flange extending from one end of the first side plate away from the second side plate to one end of the second side plate away from the first side plate, the stability and bending resistance of the purlin bracket are improved.

[0011] According to one embodiment of this application, the first flange has a notch at the connection between the first side plate and the second side plate.

[0012] According to the mounting bracket of this application, stress concentration is avoided by setting a notch in the first flange, thereby improving structural strength and stability, and at a lower cost.

[0013] According to one embodiment of this application, the cross-section of the reinforcing rib increases in the direction close to the second side plate.

[0014] According to the mounting bracket of this application, the structural strength of the purlin is improved and the cost is reduced by setting variations in the cross-section of the reinforcing ribs.

[0015] According to one embodiment of this application, the reinforcing rib extends from one end of the first side plate away from the second side plate to one end of the second side plate away from the first side plate;

[0016] or,

[0017] The reinforcing rib extends from one end of the first side plate away from the second side plate to the connection between the first side plate and the second side plate.

[0018] According to the mounting bracket of this application, by setting the length and position of the reinforcing ribs, the bending resistance and load-bearing capacity of the purlin are improved, the processing is simplified, and the use of materials is reduced while ensuring structural strength, thus lowering costs.

[0019] According to one embodiment of this application, the number of reinforcing ribs is one.

[0020] According to the mounting bracket of this application, by setting the number of reinforcing ribs, the strength of the purlin support structure is ensured while reducing costs, simplifying the processing technology, and increasing production efficiency.

[0021] According to one embodiment of this application, the second side plate has a second flange that bends toward the inclined beam.

[0022] According to the mounting bracket of this application, by setting a second flange on the second side plate, the connection strength of the purlin support to the inclined beam is improved, and the support and bending resistance are better.

[0023] According to one embodiment of this application, the first side plate forms a groove, and the outer wall of the first side plate located at the groove abuts against the purlin.

[0024] According to the mounting bracket of this application, by providing a groove in the first side plate, the distance between the first side plate and the purlin is brought closer, thereby improving fit and stability.

[0025] According to one embodiment of this application, the first side plate and the second side plate are provided with mounting holes. The first side plate is connected to the purlin through the mounting holes, and the second side plate is connected to the inclined beam through the mounting holes.

[0058] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0059] The principle of the mounting bracket 1 proposed in this application will be explained in detail below:

[0060] In related technologies, photovoltaic systems often use mounting brackets to install photovoltaic modules. In the mounting bracket, purlins and inclined beams are connected by purlin brackets. The two side plates of the purlin brackets are connected to the purlins and inclined beams respectively. Reinforcing ribs are set between the two side plates to improve structural strength. However, this method consumes a lot of materials, has a high cost, and does not effectively improve structural strength.

[0061] To solve this technical problem, this application provides a mounting bracket 1, which is described below with reference to... Figures 1-21 Description of mounting bracket 1 according to an embodiment of this application.

[0062] like Figure 1 As shown, the mounting bracket 1 of this application embodiment is applied to a photovoltaic system and includes: purlin 10, inclined beam 20 and purlin support 30.

[0063] Purlin 10 can be made of materials such as stainless steel, aluminum alloy, galvanized steel and composite materials.

[0064] In this embodiment, the purlin 10 can be made of aluminum alloy. The purlin 10 made of aluminum alloy has good corrosion resistance and is lightweight, making it easy to install and transport.

[0065] The inclined beam 20 can be made of materials such as stainless steel, aluminum alloy, galvanized steel and composite materials. The inclined beam 20 can be made of the same material as the purlin 10, or it can be made of a different material.

[0066] like Figure 1 As shown, the inclined beam 20 and the purlin 10 are arranged intersectingly.

[0067] In this embodiment, the axis of the inclined beam 20 is perpendicular to the axis of the purlin 10, resulting in good stability.

[0068] like Figure 2 , Figure 6 , Figure 10 , Figure 14 and Figure 18 As shown, the purlin bracket 30 has a first side plate 31 and a second side plate 32.

[0069] It should be noted that in the existing technology, the purlin bracket 30 needs to be treated with anti-corrosion after processing, which increases the cost and takes a long time.

[0070] In this embodiment, the first side plate 31 and the second side plate 32 can be made of zinc, aluminum, magnesium, other pre-galvanized metals or anti-corrosion materials. They can be used directly after being processed by stamping without the need for hot-dip galvanizing anti-corrosion treatment. This ensures the anti-corrosion effect of the purlin bracket 30 while reducing processing time and lowering costs.

[0071] like Figure 2, Figure 6 , Figure 10 , Figure 14 and Figure 18 As shown, the first side plate 31 and the second side plate 32 are bent and connected.

[0072] The included angle between the first side plate 31 and the second side plate 32 can be in the range of 85°-95°.

[0073] In this embodiment, the first side plate 31 and the second side plate 32 are vertically connected, and have a good fit with the purlin 10 and the inclined beam 20.

[0074] like Figure 2 , Figure 6 , Figure 10 , Figure 14 and Figure 18 As shown, the purlin 30 has a reinforcing rib 33 stamped out at least at the connection between the first side plate 31 and the second side plate 32.

[0075] In this embodiment, the purlin 30 is stamped with a reinforcing rib 33 at the connection between the first side plate 31 and the second side plate 32. In some embodiments, the reinforcing rib 33 may also extend to at least one of the first side plate 31 and the second side plate 32.

[0076] like Figure 2 , Figure 6 , Figure 10 , Figure 14 and Figure 18 As shown, the first side plate 31 abuts against the purlin 10, and the second side plate 32 abuts against the inclined beam 20.

[0077] The first side plate 31 has a first plane that is in contact with the purlin 10. The second side plate 32 has a second plane that is in contact with the inclined beam 20. The first plane extends to the end of the first side plate 31 that is away from the second side plate 32. The second plane extends from the end of the second side plate 32 that is away from the first side plate 31 to the connection between the first side plate 31 and the second side plate 32.

[0078] In this embodiment, one end of the first plane extends to the end of the first side plate 31 that is away from the second side plate 32, and the other end extends to the connection between the first side plate 31 and the second side plate 32.

[0079] In some embodiments, one end of the first plane extends to the end of the first side plate 31 opposite to the second side plate 32, and the other end may extend to the vicinity of the end of the reinforcing rib 33 opposite to the second side plate 32.

[0080] It should be noted that the first plane can be the entire sidewall of the first side plate 31 near the purlin 10, or it can be a portion of the sidewall of the first side plate 31 near the purlin 10. When the first plane is a portion of the sidewall of the first side plate 31 near the purlin 10, it is not limited to the sidewall of the first side plate 31 and the purlin 10 installation location (such as the mounting hole). The second plane can be the entire sidewall of the second side plate 32 near the inclined beam 20, or it can be a portion of the sidewall of the second side plate 32 near the inclined beam 20. When the second plane is a portion of the sidewall of the second side plate 32 near the inclined beam 20, it is not limited to the sidewall of the second side plate 32 and the inclined beam 20 installation location (such as the mounting hole).

[0081] The first side plate 31 and the purlin 10 can be connected by bolts, welding or snap-fit, and the second side plate 32 and the inclined beam 20 can also be connected by bolts, welding or snap-fit.

[0082] In this embodiment, the first side plate 31 of the purlin bracket 30 is bolted to the side wall of the purlin 10, and the second side plate 32 is bolted to the upper surface of the inclined beam 20. The connection strength is high and it is easy to disassemble and assemble.

[0083] In related technologies, photovoltaic systems often use mounting brackets to install photovoltaic modules. The purlins and inclined beams in the mounting brackets are connected by purlin supports, which are generally made of L-shaped steel plates or angle steel. The two side plates of the purlin support are connected to the purlins and inclined beams respectively. This structure cannot fully utilize the performance of steel. With the same amount of steel, the structure's resistance to deformation and ultimate bearing capacity are relatively weak. The structural strength is improved by setting reinforcing ribs between the two side plates, but this consumes a lot of material, has a high cost, and the effect of improving the structural strength is not good. In the existing technology, some purlin supports use curved side plates to avoid stress concentration and improve structural strength. However, the fit between the curved side plates and the purlins and inclined beams is not good, resulting in poor stability.

[0084] In this embodiment, the mounting bracket 1 has an inclined beam 20 and a purlin 10 arranged crosswise. The purlin support 30 has a first side plate 31 and a second side plate 32 that are bent and connected. The first side plate 31 abuts against the purlin 10, and the second side plate 32 abuts against the inclined beam 20, resulting in good fit and stability. The purlin support 30 has a reinforcing rib 33 stamped at the connection between the first side plate 31 and the second side plate 32. When the purlin 10 and the inclined beam 20 are subjected to forces in different directions due to wind or other stress conditions on the photovoltaic support, the purlin support 30 can provide good support for the purlin 10 and the inclined beam 20, improving the structural strength. The purlin support 30 is integrally stamped, with a simple structure. It does not require additional materials to make the reinforcing rib 33, resulting in lower cost and higher production efficiency. At the same time, it can use anti-corrosion treated sheet material for stamping, resulting in good anti-corrosion effect.

[0085] According to the mounting bracket 1 provided in the embodiment of this application, by setting the purlin 30 structure, it has a first side plate 31 and a second side plate 32 that are bent and connected, and at least at the connection between the first side plate 31 and the second side plate 32, a reinforcing rib 33 is stamped out. The processing is simple and efficient, ensuring structural strength and load-bearing capacity while keeping costs low.

[0086] In some embodiments, the purlin 30 may have a first flange 34.

[0087] like Figures 3-5 , Figures 7-9 , Figures 11-13 , Figures 15-17 and Figures 19-21 As shown, the first flange 34 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31.

[0088] In this embodiment, the first flange 34 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31. The first flange 34 can be folded away from the contact surface between the purlin support 30 and the purlin 10 and the inclined beam 20. The cross-sectional area of ​​the purlin support 30 along the length of the inclined beam 20 increases, the moment of inertia of the cross section increases, and the thickness and stiffness of the edge of the purlin support 30 increase. This can effectively resist local buckling, improve local stability, and improve bending resistance.

[0089] In some embodiments, the first flange 34 may also be folded toward the contact surface between the purlin support 30 and the purlin 10 and the inclined beam 20.

[0090] According to the mounting bracket 1 provided in the embodiment of this application, the stability and bending resistance of the purlin bracket 30 are improved by setting a first flange 34 extending from one end of the first side plate 31 away from the second side plate 32 to one end of the second side plate 32 away from the first side plate 31.

[0091] In some embodiments, the first flange 34 may have a notch 35.

[0092] like Figures 3-5 , Figures 7-9 , Figures 11-13 , Figures 15-17 and Figures 19-21 As shown, the notch 35 is located at the connection between the first flange 34 and the first side plate 31 and the second side plate 32.

[0093] In this embodiment, the first flange 34 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31. At the connection between the first side plate 31 and the second side plate 32, the first flange 34 has a notch 35. The notch 35 can change the stress distribution, so that the stress can be better dispersed along the edge of the notch 35, avoiding stress concentration. While ensuring structural strength and stability, it can reduce the use of some materials, thereby reducing the weight of the purlin support 30.

[0094] It is understandable that the shape and size of the notch 35 can be specifically set according to actual usage and processing requirements.

[0095] According to the mounting bracket 1 provided in the embodiments of this application, by providing a notch 35 in the first flange 34, stress concentration is avoided, structural strength and stability are improved, and the cost is low.

[0096] In some embodiments, such as Figure 5 , Figure 9 and Figure 21 As shown, the cross-section of the reinforcing rib 33 can increase along the direction closer to the second side plate 32.

[0097] The cross-section of the reinforcing rib 33 along the length of the inclined beam 20 can be triangular, arc-shaped, or other irregular shapes.

[0098] In this embodiment, the cross-section of the reinforcing rib 33 along the length of the inclined beam 20 can be triangular, and the cross-section of the reinforcing rib 33 can be increased along the direction closer to the second side plate 32. The reinforcing rib 33 adopts a variable cross-section design, which can increase the cross-sectional area in the part with greater stress and reduce the cross-sectional area in the part with less stress according to the actual stress conditions, thereby improving the structural strength while saving materials and reducing costs.

[0099] It should be noted that in some embodiments, the cross-section of the reinforcing rib 33 may also take other shapes and other variations, depending on the actual stress conditions.

[0100] According to the mounting bracket 1 provided in the embodiments of this application, the structural strength of the purlin 30 is improved and the cost is reduced by setting the cross-sectional variation of the reinforcing rib 33.

[0101] In some embodiments, such as Figures 10-13 As shown, the reinforcing rib 33 can extend from one end of the first side plate 31 away from the second side plate 32 to one end of the second side plate 32 away from the first side plate 31.

[0102] In this embodiment, the reinforcing rib 33 is in a U shape, protruding from the first side plate 31 and the second side plate 32, and the reinforcing rib 33 extends from one end of the first side plate 31 facing away from the second side plate 32 to one end of the second side plate 32 facing away from the first side plate 31. When affected by wind on a windy day or in other force-bearing situations of the photovoltaic support, the purlin 10 and the diagonal beam 20 are subjected to forces in different directions, and the purlin support 30 can provide good support for the purlin 10 and the diagonal beam 20, with strong bending resistance and easy stamping processing.

[0103] In some embodiments, as Figures 14-17 shown, the reinforcing rib 33 can extend from one end of the first side plate 31 facing away from the second side plate 32 to the connection between the first side plate 31 and the second side plate 32.

[0104] In this embodiment, the reinforcing rib 33 is in a U shape, protruding from the first side plate 31 and the connection between the first side plate 31 and the second side plate 32. The reinforcing rib 33 extends from one end of the first side plate 31 facing away from the second side plate 32 to the connection between the first side plate 31 and the second side plate 32. When affected by wind on a windy day or in other force-bearing situations of the photovoltaic support, the purlin 10 is subjected to forces in different directions, and the purlin support 30 can provide good support for the purlin 10, with strong bending resistance. At the same time, the reinforcing rib 33 at the connection also plays a certain supporting role for the diagonal beam 20. While ensuring the structural strength, the use of materials is reduced, the cost is lowered, and the stamping processing is relatively easy.

[0105] According to the mounting bracket 1 provided by the embodiment of the present application, by setting the length and position of the reinforcing rib 33, the bending resistance and bearing capacity of the purlin support 30 are improved, the processing process is simplified, the use of materials is reduced while ensuring the structural strength, and the cost is lowered.

[0106] In some embodiments, as Figures 2-21 shown, the number of the reinforcing ribs 33 can be one.

[0107] In this embodiment, the number of the reinforcing ribs 33 is one. The reinforcing rib 33 is arranged at the central position of the purlin support 30 along the length direction of the diagonal beam 20. The reinforcing rib 33 can be only arranged at the connection between the first side plate 31 and the second side plate 32, or can extend to the first side plate 31 and the second side plate 32, which can save materials, reduce costs, and simplify the processing technology while ensuring the structural strength of the purlin support 30.

[0108] According to the mounting bracket 1 provided by the embodiment of the present application, by setting the number of the reinforcing ribs 33, the cost is reduced while ensuring the structural strength of the purlin support 30, the processing technology is simplified, and the production efficiency is relatively high.

[0109] In some embodiments, as Figure 7 and Figure 8 shown, the second side plate 32 can have a second flanging 36.

[0110] The second flange 36 bends towards the inclined beam 20.

[0111] In this embodiment, a second flange 36 is provided at the end of the second side plate 32 that is away from the first side plate 31. The second flange 36 is set in the opposite direction to the first flange 34. The second flange 36 bends toward the inclined beam 20 and covers the inclined beam 20, making the connection between the purlin support 30 and the inclined beam 20 more stable and improving its bending resistance.

[0112] According to the mounting bracket 1 provided in the embodiment of this application, by setting a second flange 36 on the second side plate 32, the connection strength between the purlin support 30 and the inclined beam 20 is improved, and the support and bending resistance are better.

[0113] In some embodiments, such as Figure 19 As shown, the first side plate 31 can form a groove 311.

[0114] The outer wall of the first side plate 31 located at the groove 311 abuts against the purlin 10.

[0115] In this embodiment, the first side plate 31 can form a groove 311. The groove 311 is located at the end of the first side plate 31 away from the second side plate 32. The outer wall of the first side plate 31 at the groove 311 abuts against the purlin 10. The bending direction of the first flange 34 is opposite to the extension direction of the groove wall of the groove 311. By setting the groove 311, the distance between the first side plate 31 and the purlin 10 is closer, and the fit and stability are better. At the same time, the bending direction of the first flange 34 ensures the bending resistance of the purlin support 30.

[0116] According to the mounting bracket 1 provided in the embodiments of this application, by providing a groove 311 in the first side plate 31, the distance between the first side plate 31 and the purlin 10 is closer, thereby improving fit and stability.

[0117] In some embodiments, such as Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 11 , Figure 12 , Figure 15 , Figure 16 , Figure 19 and Figure 20 As shown, the first side plate 31 and the second side plate 32 may be provided with mounting holes 37.

[0118] The first side plate 31 is connected to the purlin 10 through the mounting hole 37, and the second side plate 32 is connected to the inclined beam 20 through the mounting hole 37.

[0119] In this embodiment, the first side plate 31 and the second side plate 32 are provided with mounting holes 37. When the reinforcing rib 33 is only located at the connection between the first side plate 31 and the second side plate 32, the mounting holes 37 are directly provided in the first side plate 31 and the second side plate 32. When the reinforcing rib 33 extends to the first side plate 31 or the second side plate 32, the mounting holes 37 are indirectly provided in the first side plate 31 or the second side plate 32 through the reinforcing rib 33 located in the first side plate 31 or the second side plate 32. The first side plate 31 is connected to the purlin 10 through the mounting holes 37, and the second side plate 32 is connected to the inclined beam 20 through the mounting holes 37.

[0120] Understandably, the size, shape, and position of the mounting hole 37 can be specifically set according to actual usage requirements.

[0121] According to the mounting bracket 1 provided in the embodiment of this application, mounting holes 37 are provided in the first side plate 31 and the second side plate 32 to facilitate the connection of the purlin bracket 30 to the purlin 10 and the inclined beam 20.

[0122] In some embodiments, the purlin 30 may be at least one of the following structural forms:

[0123] Firstly, the purlin bracket 30 has a first flange 34, and the reinforcing rib 33 is located at the connection between the first side plate 31 and the second side plate 32. The cross-section of the reinforcing rib 33 increases in the direction closer to the second side plate 32.

[0124] In this embodiment, such as Figures 2-5 As shown, the inclined beam 20 and purlin 10 are arranged intersectingly. The purlin bracket 30 has a first side plate 31 and a second side plate 32 that are bent and connected. The first side plate 31 abuts against the purlin 10, and the second side plate 32 abuts against the inclined beam 20, resulting in good fit and stability. The first flange 34 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31. The first flange 34 can be folded away from the abutting surface of the purlin bracket 30, the purlin 10, and the inclined beam 20. The purlin bracket 30 has a reinforcing rib 33 stamped at the connection between the first side plate 31 and the second side plate 32. In windy weather, it is susceptible to wind damage. When the photovoltaic support is subjected to force in different directions, the purlin 10 and the inclined beam 20 are subjected to force in different directions. The purlin bracket 30 can provide good support for the purlin 10 and the inclined beam 20, thereby improving the structural strength. The purlin bracket 30 is integrally stamped and formed, with a simple structure. There is no need to add extra material to make the reinforcing rib 33. The cross-section of the reinforcing rib 33 can be increased along the direction close to the second side plate 32. The reinforcing rib 33 adopts a variable cross-section design. According to the actual stress conditions, the cross-sectional area is increased in the parts with greater stress and reduced in the parts with less stress. This improves the structural strength while saving materials, reducing costs, and increasing production efficiency.

[0125] Secondly, the purlin bracket 30 has a first flange 34 and a second flange 36, and the reinforcing rib 33 is located at the connection between the first side plate 31 and the second side plate 32. The cross-section of the reinforcing rib 33 increases in the direction closer to the second side plate 32.

[0126] In this embodiment, such as Figures 6-9 As shown, the inclined beam 20 and purlin 10 are intersected. The purlin bracket 30 has a first side plate 31 and a second side plate 32 that are bent and connected. The first side plate 31 abuts against the purlin 10, and the second side plate 32 abuts against the inclined beam 20, resulting in good fit and stability. A first flange 34 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31. The first flange 34 can be folded away from the abutting surface of the purlin bracket 30, purlin 10, and inclined beam 20. A second flange 36 is provided at the end of the second side plate 32 away from the first side plate 31. The second flange 36 is set in the opposite direction to the first flange 34. The second flange 36 bends towards the inclined beam 20 and covers the inclined beam 20, making the connection between the purlin bracket 30 and the inclined beam 20 more stable. It is solid and has better bending resistance. A reinforcing rib 33 is stamped at the connection between the first side plate 31 and the second side plate 32. When the purlin 10 and the inclined beam 20 are subjected to forces in different directions due to wind in windy weather or other photovoltaic support conditions, the purlin bracket 30 can provide better support for the purlin 10 and the inclined beam 20, thereby improving the structural strength. The purlin bracket 30 is integrally stamped, with a simple structure and no need to add extra material to make the reinforcing rib 33. The cross-section of the reinforcing rib 33 can be increased along the direction closer to the second side plate 32. The reinforcing rib 33 adopts a variable cross-section design. According to the actual stress conditions, the cross-sectional area is increased in the part with greater stress and reduced in the part with less stress, which improves the structural strength while saving materials, reducing costs, and increasing production efficiency.

[0127] Thirdly, the purlin support 30 has a first flange 34, and the reinforcing rib 33 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31.

[0128] In this embodiment, such as Figures 10-13As shown, the inclined beam 20 and purlin 10 are intersecting. The purlin bracket 30 has a first side plate 31 and a second side plate 32 that are bent and connected. The first side plate 31 abuts against the purlin 10, and the second side plate 32 abuts against the inclined beam 20, resulting in good fit and stability. The first flange 34 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31. The first flange 34 can be folded in a direction away from the abutting surface of the purlin bracket 30, the purlin 10, and the inclined beam 20. A reinforcing rib 33 is stamped at the connection between the first side plate 31 and the second side plate 32. The reinforcing rib 33 is in the shape of a "Z" and protrudes. Starting from the first side plate 31 and the connection between the first side plate 31 and the second side plate 32, the reinforcing rib 33 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31. When the purlin 10 and the inclined beam 20 are subjected to forces in different directions due to wind in windy weather or other stress conditions of photovoltaic support, the purlin bracket 30 can provide good support for the purlin 10 and the inclined beam 20, thereby improving the structural strength. The purlin bracket 30 is integrally stamped and formed, with a simple structure. It does not require additional materials to make the reinforcing rib 33, which improves the structural strength while saving materials, reducing costs, and has high production efficiency.

[0129] Fourth, the purlin bracket 30 has a first flange 34, and a reinforcing rib 33 extends from one end of the first side plate 31 away from the second side plate 32 to the connection between the first side plate 31 and the second side plate 32.

[0130] In this embodiment, such as Figures 14-17 As shown, the inclined beam 20 and purlin 10 are intersecting. The purlin bracket 30 has a first side plate 31 and a second side plate 32 that are bent and connected. The first side plate 31 abuts against the purlin 10, and the second side plate 32 abuts against the inclined beam 20, resulting in good fit and stability. The first flange 34 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31. The first flange 34 can be folded in a direction away from the abutting surface of the purlin bracket 30, the purlin 10, and the inclined beam 20. A reinforcing rib 33 is stamped at the connection between the first side plate 31 and the second side plate 32. The reinforcing rib 33 is in the shape of a "Z" and protrudes. Starting from the first side plate 31 and the connection between the first side plate 31 and the second side plate 32, the reinforcing rib 33 extends from the end of the first side plate 31 away from the second side plate 32 to the connection between the first side plate 31 and the second side plate 32. When the purlin 10 and the inclined beam 20 are subjected to forces in different directions due to wind or other stress conditions of the photovoltaic support, the purlin bracket 30 can provide good support for the purlin 10 and the inclined beam 20, thereby improving the structural strength. The purlin bracket 30 is integrally stamped and formed, with a simple structure. It does not require additional materials to make the reinforcing rib 33, which improves the structural strength while saving materials, reducing costs, and has high production efficiency.

[0131] Fifth, the purlin bracket 30 has a first flange 34, and the reinforcing rib 33 is located at the connection between the first side plate 31 and the second side plate 32. The first side plate 31 forms a groove 311, and the cross-section of the reinforcing rib 33 increases in the direction close to the second side plate 32.

[0132] In this embodiment, such as Figures 18-21 As shown, the inclined beam 20 and purlin 10 are intersected. The purlin bracket 30 has a first side plate 31 and a second side plate 32 that are bent and connected. The first side plate 31 abuts against the purlin 10, and the second side plate 32 abuts against the inclined beam 20, resulting in good fit and stability. The first flange 34 extends from the end of the first side plate 31 away from the second side plate 32 to the end of the second side plate 32 away from the first side plate 31. The first flange 34 can be folded away from the abutting surface of the purlin bracket 30, purlin 10, and inclined beam 20. The purlin bracket 30 has a reinforcing rib 33 stamped at the connection between the first side plate 31 and the second side plate 32. When the purlin 10 and inclined beam 20 are subjected to forces in different directions due to wind or other stress conditions of the photovoltaic support, the purlin bracket 30 can provide support for the purlin 10 and inclined beam 20. To provide better support and improve structural strength, the first side plate 31 forms a groove 311, which is located at the end of the first side plate 31 away from the second side plate 32. The outer wall of the first side plate 31 at the groove 311 abuts against the purlin 10. The bending direction of the first flange 34 is opposite to the extension direction of the groove wall of the groove 311, resulting in better fit and stability. The purlin support 30 is integrally stamped, with a simple structure. No additional material is needed to make reinforcing ribs 33. The cross-section of the reinforcing ribs 33 can be increased along the direction closer to the second side plate 32. The reinforcing ribs 33 adopt a variable cross-section design. According to the actual stress conditions, the cross-sectional area is increased in the parts with greater stress and reduced in the parts with less stress, which improves structural strength while saving materials, reducing costs, and increasing production efficiency.
