支付宝工程钢结构施工方案研究

Construction scheme research of steel structure for Alipay engineering

支付宝工程采用钢框架-钢筋混凝土剪力墙结构体系,其中钢结构规模大,且形体复杂,施工难度较大.本文介绍了该结构的施工方案和施工难点,重点介绍了钢结构分段、核心筒钢结构安装、悬挑钢结构安装、大型桁架吊装等关键步骤的确定原则和施工流程,可为类似钢结构工程的施工提供有益参考.

The steel frame-reinforced concrete shear wall structure is adopted in Alipay engineering.With the large scale and complex shape,the construction of steel structure is difficult.This paper introduces the construction scheme and construction difficulties of such large complex steel structure,with a focus on the segment of steel structure,the installation of core tube steel structure,the installation of cantilever steel structure and the hoisting of large truss.The determination principle of critical steps and construction process are presented.The work here can provide useful reference for the construction of similar steel structures.
