[0002] The roof structure is a crucial part of building construction, and its construction quality directly affects the building's lifespan. With the widespread use of indoor air conditioning, it's essential to prevent heat loss in winter and cool air conduction outdoors in summer to reduce energy consumption. The air ducts under the roof are located between the roof and the roof supporting steel structure. Traditionally, to shorten the construction period, air ducts are welded to the roof supporting steel structure, requiring on-site welding, which damages the roof layer and has low construction efficiency. At the same time, the pipe support structure is complex and inconvenient to install. Utility Model Content
