精确测量在大跨度钢结构吊装中的应用

济南站站台雨棚改造工程主桁架跨度大,制作及安装精度要求高,高空精确测量是整个钢结构吊装的关键。结合该工程对测量准备、控制网建立、吊装测量等工作进行全面介绍,对大跨度钢结构的吊装具有一定的参考价值。

Accurate Measurement in Hoisting of Steel Structure with Large Span

The primary truss in canopy reconstruction of Jinan Railway Station has large span,which has a high standard for production and installation accuracy.Accurate measurement in upper-air measurement is the key to the hoisting of the whole steel structure.Based on this project,the measure ment preparation,control net establishment,hoisting measurement are introduced in an allround way.It would provide reference for the hoisting of steel structure with large span.
