[0002] With the continuous advancement and implementation of the country's "dual carbon" goals, rooftop distributed photovoltaic power stations have become one of the main forms of clean energy supply, and there are a large number of large-span public buildings such as airports, exhibitions, and stadiums, as well as the main load-bearing components of the metal roof panels of industrial buildings that connect the roof decorative panels, anti-fall systems, and lightning protection components. The connection between the photovoltaic system, decorative panel system, and some additional systems on the roof needs to ensure the reliability of the connection and the waterproofness of the roof. It is necessary to ensure the safety performance of the photovoltaic roof and decorative roof in the case of strong typhoons, and also ensure the waterproof performance of the roof to avoid roof leakage and ensure the normal use of the building. However, the connection between the photovoltaic system and the roof usually adopts a puncture connection that destroys the roof waterproofing or a clamp connection between the roof panel ribs and the roof support.
