摘要
某大跨度钢结构桁架屋盖采用滑移施工技术,施工中未采用起重机,不占用道路。现场搭设拼装胎架及脚手架操作平台,屋面桁架两榀一组原位拼装后进行滑移到位,具有现场占地小、速度快、缩短工期等优点。
Slippage technique is adopted in construction of a wide-span steel truss roof,where crane is not used and road space is not occupied.Assembly jig and scaffold operation platform are erected and every two pieces of roof truss are assembled in situ before being positioned by slippage.This construction process has many advantages,such as small site occupation,fast construction speed and short construction period,etc.
