超重柱标准节移运器吊装技术

HOISTING OF SUPER-HEAVY COLUMN BY STANDARD SEGMENT WITH SLIDING DEVICE

由于在国家会议中心地下钢结构钢柱安装过程中,有部分钢柱的重量超出了塔吊的起重能力,并且有些钢柱位置在塔吊的盲区内,为了能对这部分钢柱进行吊装,并且不另外增加大型的吊装机械,我们采用标准节移运器滑移安装方法。从这次实际应用中看,标准节移运器滑移安装方法对于因为机械性能不足的钢构件来说,是非常合适的安装方法。本文就超重钢柱标准节移运器滑移安装施工方法进行计算和阐述。

In installing the underground steel structure of the National Conference Center Project, the weight of some steel columns exceeds the load capacity of the tower crane while some column locations are beyond the crane＇s reach. Standard segment with sliding device was adopted to erect those steel columns. Practice shows that this method is quite suitable for the installation of steel structure when the capacity of site hoisting machine is insufficient. Introduction is given to the calculation and description of the construction method of super-heavy steel column by standard segment with sliding device.
