在高层建筑施工中,除了使用落地钢管脚手架外,还必须使用挑出脚手架或悬挂脚手架作为补充手段,以满足施工需要。挑出脚手架与外脚手架的主要区别在于立柱不直接支承在地面,而是支承在建筑物的某一部位上。按其支承方法不同,目前常用的挑出脚手架可分成三种:挑梁式脚手架主要借助较大的型钢横梁和三角支承架来支持上部钢管脚手架;轻型挑出脚手架主要利用落地钢管脚手架的钢管和扣件,由房屋
In the construction of high-rise buildings, in addition to the use of floor steel pipe scaffolding, scaffolding or hanging scaffolding must also be used as a supplement to meet construction needs. The main difference between picking out the scaffolding and the outer scaffolding is that the standing column is not directly supported on the ground but is supported on a certain part of the building. According to its different supporting methods, currently used picking scaffolds can be divided into three types: the cantilevered scaffolding is mainly supported by the larger steel beams and triangle support frames to support the upper steel pipe scaffolds; the lightweight picking scaffolds mainly use the steel pipes of the floor steel pipe scaffolding and Fasteners, by housing
