Description

Technical Field

[0001] This application relates to the field of photovoltaic installation technology, and in particular to a pre-tensioned, wind-resistant photovoltaic bracket for metal roofs. Background Technology

[0002] In photovoltaic systems, photovoltaic brackets are an important component, bearing the responsibility of supporting and fixing photovoltaic modules. Their design rationality and stability are related to the operating efficiency and safety of the entire photovoltaic system; especially in metal roof applications, the installation stability of photovoltaic brackets is particularly important.

[0003] Traditional metal roofing structures typically consist of multiple roof panels connected by interlocking components. These components include left and right extensions installed on adjacent roof panels, which interlock to achieve a tight connection between the panels. During installation, brackets are held between the left and right extensions of these interlocking components. The brackets are then securely connected to the roof purlins using bolts or other fasteners, thus completing the installation of the entire metal roof.

[0004] Currently, photovoltaic (PV) mounting brackets are typically installed at the interlocking points of the mounting components. To increase the stability of the PV brackets on metal roofs, slots are usually made in the interlocking components to connect the PV brackets to the components. However, because of these slots, rainwater can easily seep into the roof, thus affecting the rainproof performance of the metal roof.

[0005] Therefore, there is a need for a pre-tightening, wind-resistant photovoltaic bracket for metal roofs that can increase the stability of the photovoltaic bracket at the interlocking point on the metal roof while maintaining the rainproof performance of the metal roof. Utility Model Content

[0006] In order to improve the wind resistance stability of photovoltaic brackets installed on metal roofs while maintaining the rainproof effect of metal roofs, this application provides a pre-tensioned wind-shearing photovoltaic bracket for metal roofs.

[0007] The pre-tensioned wind-shearing photovoltaic bracket for metal roofing provided in this application adopts the following technical solution:

[0008] A pre-tensioned, wind-resistant photovoltaic bracket for a metal roof includes fasteners, T-shaped members, and connecting components. The fasteners and T-shaped members are clamped on opposite sides of an interlocking component. The T-shaped members are used to connect to photovoltaic modules. Two limiting plates are provided on the side of the fastener near the T-shaped member, with a gap between the two limiting plates. The interlocking part of the interlocking component is inserted into the two limiting plates. The connecting component includes a first bolt and a nut. The fastener has a first mounting hole, and the T-shaped member has a second mounting hole that is directly opposite the first mounting hole. The first bolt passes through the first mounting hole and the second mounting hole and cooperates with the nut.

[0009] By adopting the above technical solution, when installing photovoltaic panels on a metal roof, the interlocking joint is first inserted between two limiting plates. A first bolt passes through the first mounting hole of the fastener and the second mounting hole of the T-shaped component, and engages with a nut to connect the T-shaped component and the fastener. During tightening, a pre-tightening force is applied by rotating the nut, creating a clamping force between the fastener and the T-shaped component, thus securing the interlocking joint of the interlocking assembly between them. The simultaneous installation of two limiting plates prevents the interlocking joint from detaching from the fastener and T-shaped component under extreme weather conditions, thereby improving the wind resistance and stability of the bracket installation on the metal roof, reducing the risk of wind uplift, and enhancing the overall safety of the system.

[0010] In addition, this structure eliminates the need for slots in the metal roof, thus preventing rainwater from seeping between the left and right extensions through the slots and maintaining the waterproof performance of the metal roof.

[0011] Optionally, the fastener is provided with a first positioning plate, and the T-shaped member is provided with a second positioning plate for abutting against the first positioning plate.

[0012] By adopting the above technical solution, the first positioning plate and the second positioning plate are abutted together so that the first mounting hole and the second mounting hole are aligned, thereby improving the assembly efficiency of the fastener and the T-shaped piece of the connecting assembly.

[0013] Optionally, the bracket is located between the fastener and the T-shaped member.

[0014] By adopting the above technical solution, the force on the support can be transferred to the roof by clamping the support between the fastener and the T-shaped piece, thereby forming a more stable structural system and further reducing the loosening or displacement of the photovoltaic support caused by wind load, temperature change and other factors.

[0015] Optionally, the nuts are provided in two sets, and both sets of nuts cooperate with the first bolt.

[0016] By adopting the above technical solution and setting two sets of nuts, the bolts can be prevented from loosening due to vibration or external load, thereby improving the stability of the photovoltaic bracket installed on the metal roof.

[0017] Optionally, the two limiting plates are integrally formed with the fasteners.

[0018] By adopting the above technical solution, the one-piece molding design ensures that there are no additional seams or connection points between the limiting plate and the fastener, thereby ensuring that the bracket can remain stable under severe weather conditions such as strong winds.

[0019] Optionally, a rubber block is provided on the side of the limiting plate near the T-shaped piece.

[0020] By adopting the above technical solution, as the fastener and T-shaped component approach each other, the two rubber blocks can fit tightly against the sidewalls of the T-shaped component and the interlocking component respectively, further improving the stability of the photovoltaic bracket installed on the metal roof.

[0021] Optionally, one of the limiting plates is equipped with a second bolt, which is rotatably mounted with a clamping plate located between the two limiting plates for abutting against the engagement point of the engagement assembly.

[0022] By adopting the above technical solution, since the clamping plate can be adjusted by the second bolt, it can be ensured that the clamping plate and another limiting plate can fit tightly with the interlocking component and the interlocking point, thereby enhancing the structural stability of the entire support system and further reducing the possibility of the support detaching from the metal roof under extreme weather conditions.

[0023] Optionally, the outer wall of the second bolt is covered with a rubber layer.

[0024] By adopting the above technical solution and setting a rubber layer, the friction between the second bolt and the limiting plate can be increased, thereby preventing the second bolt from rotating freely on the limiting plate and improving the stability of the second bolt on the limiting plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up connecting components and applying preload by rotating the nut, a clamping force is formed between the fastener and the T-shaped piece, so that the interlocking part of the interlocking component is clamped between the fastener and the T-shaped piece. This can prevent the interlocking part of the interlocking component from detaching from the fastener and the T-shaped piece under extreme weather conditions, thereby improving the stability of the bracket installation on the metal roof, reducing the risk of wind uplift, and improving the overall safety of the system. Moreover, this structure does not require slots to be made in the metal roof, thereby preventing rainwater from seeping between the left extension and the right extension through the slots, thus maintaining the waterproof performance of the metal roof.

[0027] 2. By setting a retaining plate, which can be adjusted by a second bolt, it is ensured that the retaining plate and another limiting plate can fit tightly with the interlocking components and the interlocking point, thereby enhancing the structural stability of the entire support system and further reducing the possibility of the support detaching from the metal roof under extreme weather conditions.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] Example 1:

[0035] This application discloses a pre-tensioned wind-shearing photovoltaic bracket 6 for a metal roof. The bracket is installed on a metal roof, which includes multiple roof panel bodies 4 installed on the roof and brackets 6 installed between adjacent roof panel bodies 4. Adjacent roof panel bodies 4 are connected by interlocking components 5. The interlocking components 5 include a left extension 51 and a right extension 52 respectively installed on two adjacent roof panel bodies 4. The left extension 51 and right extension 52 interlock and engage. When the roof panel body 4 is installed on the roof, the bracket 6 is clamped between the left extension 51 and right extension 52 of the interlocking components 5. Then, a third bolt 61 securely connects the bracket 6 to the roof's purlins, thus completing the connection between the roof panel body 4 and the roof.

[0036] Reference Figure 1A pre-tensioned wind-resistant photovoltaic bracket 6 for metal roofs includes a fastener 1, a T-shaped member 2, and a connecting assembly 3. The connecting assembly 3 is used to connect the fastener 1 and the T-shaped member 2. The fastener 1 and the T-shaped member 2 are clamped on opposite sides of an interlocking assembly 5, and the bracket 6 is located between the fastener 1 and the T-shaped member 2, so as to transfer the wind load on the bracket 6 to the roof through the bracket 6, thereby improving the stability of the bracket installed on the metal roof.

[0037] Two limiting plates 11 are integrally formed on the side of the fastener 1 near the T-shaped part 2. The width of the limiting plate 11 is smaller than the width of the biting part of the biting component 5, and there is a gap between the two limiting plates 11. When the fastener 1 and the T-shaped part 2 are clamped on opposite sides of the biting component 5, the biting part of the biting component 5 is inserted between the two limiting plates 11, and the two limiting plates 11 abut against the upper and lower sides of the biting part of the biting component 5, respectively.

[0038] The connecting assembly 3 includes a first bolt 31 and a nut 32. The fastener 1 has a first mounting hole 16, and the T-shaped part 2 has a second mounting hole 22. The first bolt 31 passes through the first mounting hole 16 and the second mounting hole 22 and cooperates with the nut 32 so that the fastener 1 and the T-shaped part 2 can be clamped between the head of the first bolt 31 and the nut 32.

[0039] The fastener 1 is integrally formed with a first positioning plate 12, and the T-shaped part 2 is integrally formed with a second positioning plate 21 for abutting against the first positioning plate 12. When the first positioning plate 12 and the second positioning plate 21 abut against each other, the first mounting hole 16 and the second mounting hole 22 are positioned opposite each other.

[0040] The implementation principle of Embodiment 1 of this application is as follows:

[0041] When installing the photovoltaic array on a metal roof, the interlocking joint is first inserted between two limiting plates 11. A first bolt 31 passes through the first mounting hole 16 of the fastener 1 and the second mounting hole 22 of the T-shaped component 2, and engages with the nut 32, thus connecting the T-shaped component 2 and the fastener 1. During tightening, a pre-tightening force is applied by rotating the nut 32, creating a clamping force between the fastener 1 and the T-shaped component 2, clamping the interlocking joint of the interlocking assembly 5 between the fastener 1 and the T-shaped component 2. The simultaneous installation of two limiting plates 11 prevents the interlocking joint of the interlocking assembly 5 from detaching from the fastener 1 and the T-shaped component 2 under extreme weather conditions, thereby improving the stability of the bracket 6 installed on the metal roof, reducing the risk of wind uplift, and enhancing the overall safety of the system.

[0042] In addition, this structure eliminates the need for slots in the metal roof, thus preventing rainwater from seeping between the left extension 51 and the right extension 52 through the slots, thereby maintaining the waterproof performance of the metal roof.

[0043] Example 2:

[0044] This application discloses a pre-tensioned wind-resistant photovoltaic bracket 6 for metal roofs.

[0045] Reference Figure 2 and Figure 3 The difference between Embodiment 2 and Embodiment 1 is that two nuts 32 are provided, and both nuts 32 are engaged with the first bolt 31. When both nuts 32 are engaged with the first bolt 31, the two nuts 32 abut against each other; this can prevent the bolt from loosening due to vibration or external load, thereby improving the stability of the photovoltaic bracket 6 installed on the metal roof.

[0046] One of the limiting plates 11 is provided with a retaining plate 13. One side of the retaining plate 13 abuts against the fastener 1, and the retaining plate 13 is located between the two limiting plates 11. The limiting plate 11 is provided with a threaded groove 14. A second bolt 15 is installed in the threaded groove 14, and the second bolt 15 is rotatably connected to the retaining plate 13.

[0047] The implementation principle of Embodiment 2 of this application is as follows:

[0048] Since the clamping plate 13 can be adjusted by the second bolt 15, it can be ensured that the clamping plate 13 and the other limiting plate 11 can fit tightly with the interlocking component 5 and the interlocking point, that is, the bracket 6 can fit tightly with the interlocking component 5 of different sizes; thereby enhancing the structural stability of the entire bracket 6 system and further reducing the possibility of the bracket 6 detaching from the metal roof under extreme weather conditions.

[0049] Example 3:

[0050] This application discloses a pre-tensioned wind-resistant photovoltaic bracket 6 for metal roofs.

[0051] Reference Figure 4 The difference between Embodiment 3 and Embodiment 1 is that: a rubber block 17 is pasted on the side of the limiting plate 11 away from the fastener 1; when the connecting component 3 brings the fastener 1 and the T-shaped component 2 closer to each other, the two rubber blocks 17 deform and are always tightly attached to the side wall of the T-shaped component 2 / interlocking component 5, thereby improving the stability of the photovoltaic bracket 6 installed on the metal roof.

[0052] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
