There are many counterweight concrete piers and a large roof load; it occupies a large space and has a very limited obstacle avoidance ability; the installation is complex and has a long period of time, and there are many small parts and accessories; the overall structural strength is average, and the wind resistance is not strong. The bracket structure is safe and reliable, with a small amount of foundation engineering, strong wind resistance, low construction cost, small footprint, strong pre-installation, and high space utilization. The steel strands transfer the weight of the photovoltaic components, wind loads, snow loads, etc. to the concrete piers and roof.

[0003] At present, the roof photovoltaic support system is basically a counterweight fixed support. The photovoltaic support is connected to the concrete pier through pre-buried U-shaped bolts. The concrete pier transfers the weight of the photovoltaic module, the weight of the photovoltaic support, wind load, snow load, etc. to the concrete roof.

[0004] Traditional roof counterweight fixed brackets have the problems of large space occupation, complex installation, low space utilization, long construction period and potential safety instability. Utility Model Content

Therefore, under the action of the same bending moment, the strength of the side beam column is higher, and the side beam column has a larger cross-sectional moment of inertia, which means that the side beam column has greater rigidity. The central beam bracket is set to support the steel strands and avoid direct installation of the steel strands on the top of the central beam H-shaped steel. It can be modularly produced in the factory with high clearance, which improves the utilization rate of the roof space. The number of counterweight concrete piers is small, which reduces the roof load. It is easy to install, the overall structure is stable, and the wind resistance is strong.
