悬挑外脚手架底部支撑体系的设计改进

Design Improvement of the Bottom Support System of Cantilevered External Scaffolding

现行的一般高层民用建筑外脚手架通常采用普通型钢悬挑外脚手架,其底部支撑体系通常采用型钢悬挑支撑体系。这种传统的悬挑外脚手架支撑体系,存在诸多弊端。为解决这些弊端,一种新型的悬挑外脚手架底部支撑体系——斜拉支撑体系出现在实际工程中。通过对悬挑外钢管扣件式脚手架斜拉支撑体系的性能分析,推广建筑脚手架施工新技术在高层建筑外脚手架工程中的应用,可以从施工工艺上最大程度地降低甚至消除脚手架传统悬挑型钢支撑体系对建筑物外墙产生不利影响,推进绿色建筑施工技术的发展。

The current external high-rise civil building scaffolding usually adopts ordinary steel cantilevered external scaffolding,and its bottom support system usually adopts profiled steel cantilever support system.There are many disadvantages to this traditional cantilevered external scaffolding support system.To address these shortcomings,a new type of cantilevered external scaffold bottom support system,the cable-stayed support system,appears in actual engineering.Through the performance analysis of the cantilever outer steel tube fas tener type scaffolding cable-stayed support system,the applicat ion of the new construction scaffolding construction technology in the high-rise building outer scaffolding project can be used to reduce or even eliminate the traditional scaffolding cantilever steel from the construction process The support system has an adverse effect on the external walls of the building and promote s the development of green building construction technology.
