AI Technical Summary
In existing technologies, when photovoltaic panel supports are installed on steel structure waterproof roofs, holes need to be drilled in the waterproof layer and the insulation layer, resulting in poor waterproofing and easy condensation, which affects roof leakage.
The system employs a waterproof disc assembly and mounting screw kit, including a stainless steel metal support ring, TPO waterproof membrane, anti-cold bridge PE plastic cylinder, and fixing clamps. Waterproofing and anti-cold bridge effects are achieved through hot-melt welding and threaded connection. The support installation process does not require drilling holes in the roof.
It enables quick and convenient installation of photovoltaic panel supports on steel structure waterproof roofs, ensuring waterproofing, preventing condensation, and reducing construction costs.
