Construction Technology Analysis of Integral Jacking Method for Spherical Steel Structure Space Truss

焊接球形钢网架结构普遍应用于高铁站房、机场、体育馆等较大公共性建筑的屋顶工程。文中对大西高铁侯马西站站房扩建工程球形钢网架结构安装施工实例进行了总结分析,采用整体顶升法安装钢结构网架可以降低安全风险,减少投入,节约成本,加快施工进度,提高项目的经济效益。

Welded spherical steel grid structures have been widely used in the roof works of large public buildings such as high-speed railway station buildings,airports and gymnasiums.With the continuous expansion of construction scale,the traditional steel grid installation construction method has high safety risk and slow construction progress.This paper summarizes and analyzes the installation and construction of spherical steel grid structure in the expansion project of Houmaxi Station of Daxi High-speed Railway undertaken by the Second Company.The installation of steel grid structure by the integral jacking method can reduce safety risks,reduce investment,save costs,speed up the construction progress and improve the economic benefits of the project.
