[0018] In the following description, embodiments of the photovoltaic bracket pre-embedded steel pipe concrete exterior wall panel of this utility model will be described with reference to the accompanying drawings.

[0019] Figure 1-4This invention illustrates a photovoltaic bracket-embedded steel-tube concrete exterior wall panel according to an embodiment of the present invention. The panel includes an exterior wall panel 1, with four cast-in-place steel pipes 2 embedded inside. Both ends of the cast-in-place steel pipes 2 extend to the outer side of the exterior wall panel 1. The cast-in-place steel pipes 2 can also serve as photovoltaic sleeves for connection in prefabricated buildings. A reinforcing cage 11 is embedded inside the exterior wall panel 1. Multiple connecting reinforcing bars 12 are welded to the surface of the cast-in-place steel pipes 2. One side of each connecting reinforcing bar 12 is welded to the reinforcing cage 11. The connecting reinforcing bars 12 increase the connection strength between the cast-in-place steel pipes 2 and the reinforcing cage 11, effectively improving the stability of the cast-in-place steel pipes 2 within the reinforcing cage 11. To effectively prevent the steel pipes 2 from shifting due to concrete impact, steel plates 3 are installed on the surfaces of the two steel pipes 2. Two round holes 8 are opened at both ends of the steel plates 3. U-shaped hoops 9 are fitted onto the surface of the steel pipes 2 through the inner cavity of the two round holes 8. Nuts 10 are threaded onto both ends of the surface of the U-shaped hoops 9. The nuts 10 abut against the steel plates 3. A through-hole 4 is opened in the middle of the steel plates 3. A photovoltaic bracket base 5 is set on the front side of the through-hole 4. Fastening bolts 6 slide in the inner cavity of the through-hole 4 through the photovoltaic bracket base 5. Through holes 7 are opened on the photovoltaic bracket base 5 for the fastening bolts 6 to pass through. The photovoltaic bracket base 5 is fixedly installed on the steel plates 3 by the fastening bolts 6. The installation end of the photovoltaic bracket base 5 extends to the outer side of the outer wall panel 1.

[0020] Working principle: When using this utility model, a steel cage 11 is erected in the mold, and the cast steel pipe 2 is placed in the steel cage 11 and welded. Then, the steel plate 3 is installed on the two cast steel pipes 2 through U-shaped hoops 9 and nuts 10, so that the steel plate 3 faces the top. Next, the photovoltaic bracket base 5 is installed on the steel plate 3 by fastening bolts 6. The fastening bolts 6 can slide in the inner cavity of the long opening 4 to adjust the horizontal distance between the two photovoltaic bracket bases 5. After the adjustment is appropriate, the fastening bolts 6 are tightened to firmly fix the photovoltaic bracket base 5 on the steel plate 3, ensuring the stability of the photovoltaic bracket base 5. Then, concrete is poured to expose the installation end of the photovoltaic bracket base 5. The top concrete is smoothed. After the concrete has solidified, the mold can be removed. The photovoltaic bracket base 5 pre-embedded in the wall can be used for the installation of photovoltaic panels.

[0021] In summary: This photovoltaic bracket-embedded steel pipe concrete exterior wall panel is constructed by erecting a reinforcing cage 11 in a mold and welding the cast steel pipes 2 inside the cage 11. Then, steel plates 3 are installed on the two cast steel pipes 2 using U-shaped hoops 9 and nuts 10. The photovoltaic bracket base 5 is then installed on the steel plate 3 using fastening bolts 6. Moving the fastening bolts 6 adjusts the horizontal spacing between the two photovoltaic bracket bases 5. After adjustment, the fastening bolts 6 are tightened, and then concrete is poured, exposing the installation end of the photovoltaic bracket base 5. Once solidified, the photovoltaic bracket is embedded in the exterior wall panel and reinforced with the steel pipes, ensuring stability without damaging the exterior wall panel.
