[0019] See also Figure 1-2This embodiment provides a photovoltaic roof surface structure. The base of the photovoltaic mounting bracket is pre-buried and cast together with the concrete. The photovoltaic mounting bracket is waterproofed, sealed and thermally insulated. While ensuring the integrity of the roof, it has the advantages of waterproofing and heat preservation, high connection strength, and reliable force. It solves the problems of the current traditional installation method that uses a large amount of reinforced concrete and has the potential for leakage and thermal bridges.

The photovoltaic connectors are the photovoltaic mounting bracket connection base 10, hard polyurethane pads 11, bolts 12, sealant 13, and photovoltaic mounting bracket 14.

[0021] The photovoltaic mounting bracket connection base 10 (hereinafter referred to as the "base") is pre-buried and cast together with the base concrete. The bottom of the base 10 is notched and laid on top of the steel bars, and can be fixed by steel wire tying. The first waterproof layer 2 uses waterproof paint, with an upward bead at the base, forming a dense waterproof system with the main body. The base 10 is connected to the photovoltaic mounting bracket 14 by bolts, with a hard polyurethane pad 11 placed in the middle to prevent thermal bridges. The slope and leveling layer 5 is sealed with sealant at the photovoltaic mounting bracket 14. The second and third waterproof layers 6 and 7 are both made of waterproof membrane, and the second waterproof membrane is beaded upward at the photovoltaic mounting bracket to further enhance the waterproof performance of the connection. Under this structure, the connection between the photovoltaic mounting bracket and the main body forms a complete and dense integrated waterproof and thermal insulation system.

[0022] Continue to see Figure 1 The photovoltaic mounting bracket connection base 10 is pre-buried and cast together with the base concrete. The upper part of the photovoltaic mounting bracket connection base 10 is connected to the photovoltaic mounting bracket 14 with bolts 12, and a hard polyurethane pad 11 is placed in the middle to perform thermal bridge treatment.

[0023] The bottom of the photovoltaic mounting bracket connection base 10 has a plurality of notch structures, which are overlapped and laid on top of the steel bars and fixed by steel wire binding.

[0024] The connection between the photovoltaic mounting bracket connection base 10 and the photovoltaic mounting bracket 14 is a flange structure, and the bolts 12 pass through the hard polyurethane pad 11; the connection is located at the insulation layer 4.

[0025] In this embodiment, a sealant 13 is provided around the slope and leveling layer 5 adjacent to the photovoltaic mounting bracket 14 .

Furthermore, thermal bridge protection is implemented at the connection between the photovoltaic bracket connection base and the photovoltaic mounting bracket, ensuring continuous insulation throughout. The photovoltaic mounting bracket and the main structure form a complete and dense, integrated waterproof and thermal insulation system. This effectively solves the problems of traditional reinforced concrete installation methods, such as long construction times and the potential for leakage and thermal bridges caused by drilling installation. This improves the overall quality of the building and reduces resource consumption.
