[0002] With the rapid development of the construction industry, the application scope of steel structure buildings is becoming wider and wider. Steel structures are widely used due to their high strength, good toughness, good deformation capacity, high reliability, and good seismic performance. Moreover, steel structure components can be manufactured in factories and installed on site. They can actively respond to national policies and help promote industrial upgrading and industrial development in the construction industry.

[0003] In the related art, the roof is an important structure at the top of the building, and the roof panel is an important structure of the roof, which can provide a windproof effect and prevent rainwater from entering the room. The existing roof is usually constructed by cast-in-place concrete to complete the construction of the roof.
