Background

With the strong support of the photovoltaic industry in China, the choice of the photovoltaic system for the installation place is more and more, but the installation of the photovoltaic system not only needs to consider the photovoltaic, but also needs to consider the place requirement. The photovoltaic system on the general steel structure factory building is fixed by means of the color steel plate and the purline; however, due to the limitation of building time, production flow and waterproof and anti-corrosion requirements of each plant, the requirements of safe use of the plant cannot be met by partial roof construction common photovoltaic systems. The scarcity of roofs has limited the development of distributed photovoltaics, and the importance of waterproof designs for photovoltaic scaffolding systems is becoming increasingly prominent.

The existing waterproof bracket design of the trapezoid tile roof is mainly cut into from two aspects of a trapezoid tile clamp and a bracket, however, the common trapezoid tile roof uses a common trapezoid tile clamp to fix the clamp by gluing on the roof or using self-tapping screws to damage the roof, then a photovoltaic panel is installed on the clamp, and the common integral roof photovoltaic bracket is generally supported by the clamp only; the disadvantage of this is that on one hand, the requirement of glue fixing on the construction environment is high, and the weather is suitable, and on the other hand, if the self-tapping screw is adopted for fixing, water is easy to leak; and as the current assembly becomes larger and heavier, the method is easier to cause hidden cracking risk of the assembly and increases the pressure of the clamp.
