大跨度体育馆钢桁架屋面施工技术

摘要

Taking a comprehensive gymnasium steel truss construction as an example,according to the limited engineering construction site work space,unable to carry on truss integral hoisting,using the method interrupting slice hoisting implementation of integral assembly after air weld-ing,and introduced the specific process and its operation key points of the steel truss construction technology,had positive promoting role for the development and innovation of steel truss technology.%以某综合体育馆钢桁架施工为例，针对该工程施工现场作业场地有限，无法进行桁架的整体吊装的情况，采用打断分片吊装在空中焊接后实现整体拼装的方法，并介绍了该钢桁架施工技术的具体工艺流程及其操作要点，对钢桁架技术的发展和创新具有积极的促进作用。
