Airports, stations, docks, large buildings, etc. have risen rapidly, and the supporting membrane structure channels have been widely used. Relying on the advantages of beautiful appearance, energy conservation and environmental protection, short construction period, and high strength, the membrane structure channels have been widely used in various scenarios and gradually replaced the traditional cement structures. However, due to the limitations of the structural form, most of the membrane structures are landscape buildings and are formed by on-site cutting, assembling, and welding. The top structure of the traditional steel corridor steel structure corridor is usually covered with metal or concrete roof coverings, such as metal plates and roof tiles. The top of some steel structure corridors may be designed as a sunshade structure to provide shade and protection functions. These structures can be built with lightweight steel structures or aluminum alloys and covered with sunshade panels, sunshade cloth, or other sunshade materials. However, the above structures generally need to be built on the construction site, resulting in poor control of the technical level of workers and greater influence of factors such as weather, temperature, humidity, and wind on the welding and installation quality.
