[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0030] Combine Figures 1 to 5 As shown, this embodiment is a roof photovoltaic support structure, including multiple support pads 4, horizontal and vertical rail assemblies, a longitudinal fixing assembly 1 and a horizontal fixing assembly. The roof is paved with support pads 4, and multiple support pads 4 are distributed at intervals. The horizontal and vertical rail assemblies are installed on the support pads 4 via fixing parts. The longitudinal ends of the horizontal and vertical rail assemblies are provided with longitudinal fixing assemblies 1, and the longitudinal fixing assemblies 1 are used to fix the longitudinal ends of the horizontal and vertical rail assemblies to the wall surfaces of the walls at both ends of the roof. The transverse ends of the horizontal and vertical rail assemblies are provided with transverse fixing assemblies, and the transverse fixing assemblies are used to fix the transverse ends of the horizontal and vertical rail assemblies to the wall surfaces of the walls on both sides of the house.

[0031] In some embodiments, as Figure 2As shown, the horizontal and vertical rail assembly includes a longitudinal rail 2, a transverse rail 3, and fasteners 9. The longitudinal rail 2 and transverse rail 3 are arranged in a horizontal and vertical configuration. Fasteners 9 secure the longitudinal rail 2 and transverse rail 3 at their intersection to ensure the stability of the photovoltaic bracket from front to back and from side to side. Specifically, in this embodiment, the fasteners utilize self-tapping screws 11, which secure the longitudinal rail 2 and transverse rail 3 to the support pad 4. In this embodiment, the ends of the longitudinal rail 2 can extend along the wall surface to serve as grounding material, saving engineering costs and improving work efficiency.

[0032] Further, such as Figure 3 As shown, the longitudinal fixing assembly 1 includes a square steel tube 7, a circular steel tube 6, and a chemical anchor 8. Multiple square steel tubes 7 are connected to form a triangular support structure, which is fixed to the wall surface via chemical anchors 8. A circular steel tube 6 is welded to the side of the triangular support structure near the roof eaves. The end of the longitudinal rail 2 is wrapped around the circular steel tube 6 and fixed to the wall surface via chemical anchors 8. The longitudinal rail 2 achieves a smooth transition by fitting over the circular steel tube 6, avoiding stress concentration at the transition point and ensuring a stable and reliable connection.

[0033] Further, such as Figure 4 As shown, the transverse fixing assembly includes chemical anchor bolts 8 , and the ends of the transverse rails 3 extend to the wall surfaces on both sides of the roof and are fixed to the wall surfaces via the chemical anchor bolts 8 .

[0034] In some embodiments, as Figure 5 As shown, the horizontal and vertical rail assembly is mounted with a photovoltaic module via an installation assembly. The installation assembly includes a pressure block 5, a bolt 12, and a nut 10. The pressure block 5 secures the photovoltaic module to the vertical rail 2 through the connection between the bolt 12 and the nut 10. The pressure block 5 can press and secure the photovoltaic module. Specifically, the nut 10 can be pre-welded to the lower surface of the horizontal rail 3, and then the bolt 12 is used to connect the nut 10 to secure the photovoltaic module.

[0035] In some embodiments, a rail slot is provided on the top of the support pad 4, and the longitudinal rail 2 and the transverse rail 3 can be engaged with the rail slot. The rail slot can ensure that the rails are stably connected. The bottom of the support pad 4 is treated with anti-slip treatment, and the anti-slip treatment can prevent the support pad 4 from slipping, thereby ensuring lateral and longitudinal safety and stability.

[0036] The implementation principle of a roof photovoltaic support structure is as follows:

[0037] By connecting the longitudinal rail 2 and the transverse rail 3 with fasteners 9 to form a transverse rail assembly, by laying a support block 4 on the top of the roof, the longitudinal rail 2 and the transverse rail 3 are installed with the help of the support block 4, and then the end of the longitudinal rail 2 is fixed by the longitudinal fixing assembly 1, and the end of the transverse rail 3 is fixed by the transverse fixing assembly. The overall structure can avoid damaging the roof structure, thereby preventing roof leakage.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
