Scaffolding is a temporary support structure erected in steel structure construction to provide working platforms for workers, material storage, and safe operations. It is typically composed of steel pipes, couplers, scaffold boards, and connecting components. In steel structure engineering, scaffolding not only offers stable working platforms for high-altitude operations but also bears the load of temporarily stacked components and construction materials, making it a critical auxiliary facility for ensuring construction progress and safety. Its erection methods are flexible and diverse, allowing adjustments in height, span, and layout according to building configurations and construction requirements. Common types include coupler-type, bowl-type, and disc-type scaffolding, among which disc-type scaffolding is particularly widely used in large-scale steel structure projects due to its high load-bearing capacity and efficient assembly and disassembly. The design of scaffolding requires careful calculation of loads and stability to ensure safety and reliability under complex conditions such as wind loads, dynamic loads, and eccentric loads. Meanwhile, its modular component system facilitates repeated use, reducing project costs while embodying the concept of green construction.
