大跨度空间钢管结构安装技术分析

Research on Installation Technology of Large Span Steel-pipe Structure

近年来,钢管结构在体育馆、机场、展览中心等建筑中得到了大量的应用。随着钢管结构的不断应用和发展,钢管结构的安装技术得到进一步研究和提高,尤其对于大跨钢管结构,安装作为工程施工的主要部分,决定着工程的顺利进行。本文根据实际工程介绍了该工程的安装工艺,吊装方案优选和验算,起拱计算和支撑胎架设计,主要连接节点的焊接。

The steel-pipe structure has been used widely in buildings such as gymnasium, airport and exhibition hall. With the development and use of steel-pipe structure, the installation technology of it has been researched. Especially for large span steel-pipe structure, the installation which is the main part of the construction can determine whether the construction can process successfully. This paper introduced the installation technology, the selective preference of lifting, the checking calculation of lifting, calculation of arch rising, and the main welding connections of a real structure.
