Description

A roof photovoltaic bridge support system

technical field

The utility model relates to a roof photovoltaic support system, in particular to a bridge-type support system structure of a trapezoidal profiled steel plate roof photovoltaic power station.

Background technique

The land resources of traditional ground-mounted photovoltaic power plants are becoming more and more scarce, and the use of large areas of idle roofs such as shopping malls, schools, and industrial plants to build distributed photovoltaic power plants is becoming more and more popular. According to the structural form, the roof photovoltaic power station can be divided into reinforced concrete structure and profiled steel structure roof. Different types of roofs must adopt corresponding fixing and supporting structures. Reinforced concrete structure roofs generally use concrete blocks or expansion bolts to fix the photovoltaic module brackets. Due to the large safety margin in the design process, the calculation of the bearing capacity of a photovoltaic power station on a reinforced concrete roof can generally pass, and only waterproof structural measures need to be strengthened . Steel structure roofs can generally be divided into two types: angle-shaped and trapezoidal-section profiled steel plates. Angle-shaped profiled steel plate roofs can directly use metal clamps to fix photovoltaic modules without opening holes in the original roof structure, so there are fewer hidden dangers of waterproofing. Small. The trapezoidal profiled steel plate structure often needs to be fixed with piercing bolts and supported by specific metal fixtures, which will cause greater damage to the original roof structure and a greater risk of water leakage. Moreover, profiled steel plate roofs mostly use plates with a thickness of 0.5 mm to 1 mm, and thinner profiled steel plates with a thickness of 0.5 mm to 0.6 mm are used more and more, with low structural strength and small bearing capacity margin. The safety risk of roof photovoltaic power station is relatively high.
