【摘要】苏州现代传媒广场项目酒店楼外围护采用集成式升降脚手架,该平台工厂预制,然后在现场组装,相比传统悬挑脚手架而言大幅度减小高空搭设作业的危险性。本文结合该项目实际情况,选择适合该项目的架体形式,施工前进行了合理的策划设计及平面优化布置,经专家论证后实施,改变了超高层外脚手架搭设传统作业方式,达到良好的经济和社会效益。

Abstract: The hotel building's envelope of Modern Media Square project in Suzhou uses integrated lifting scaffold, the platform is prefabricated in factory, and then is assembled at site. Comparing to the traditional cantilever scaffold, the platform significantly reduce the risk of high erection work. Combination with the practical situation of this project, the frame body form suitable for the project is chosen, reasonable design and optimization arrangement of plan before construction are determined which can change traditional working style on super-high-rise outside scaffolding and achieve good economic and social benefits.

拼装不占用施工场地,可以同时满足楼层结构施工。
缺点:①超高层建筑风速较大,架体结构需要额外措施才能满足风荷载要求;②在高空搭设悬挑脚手架,荷载大,危险性高;③密目网、竹排片等易燃材料对超高层施工带来极大安全隐惠;④架体立杆相互间挂接作业速度较慢,搭设时间较长,且挂接质量对整体稳定性影响较大;③在架体搭设过程
