多层或高层建筑物为满足结构施工操作要求,需要搭设外脚手架。外脚手架的类型有落地式、悬挑式、整体提升式三大类。落地式脚手架操作简单、相对稳定、安全,但搭设所需的周转材料用量较大,且受高度限制,双排落地式比较适合小高层及高层建筑。整体提升脚手架安全性较好,使用方便,但设备投入较大。江苏省射阳电信生产楼工程为14层塔
For multi-storey or high-rise buildings to meet the requirements of structural construction operations, external scaffoldings need to be erected. There are three types of external scaffolding: floor-standing, cantilevered, and integral lifting. Floor-standing scaffolding is simple, relatively stable, and safe, but it requires a large amount of turnover materials and is highly limited. Double-row landings are more suitable for small high-rises and high-rise buildings. The overall improvement of scaffold safety is good, easy to use, but the equipment investment is large.
