深圳免税大厦外墙脚手架悬挑技术

Construction technology of external cantilevered scaffold in the works of duty-free building in Shenzhen

结合工程实例,介绍了型钢悬挑外架的材料选择、搭设分段、施工步骤,并对悬挑体系的受力进行了验算,结果显示架体的悬挑体系是安全的,型钢悬挑技术可以推广应用。

Combined with practical work the construction step of cantilevered shape steel scaffold is introduced fromn material selection, rerction and other aspects. Analysis of the mechanical behaviors of cantilevered system shows this system is safe and cantilevered shape steel scaffold is practicable.
