Construction Technology of Reverse Method Using Cast-in Site Concrete Structural Columns as Intermediate Bracing Ones

本文通过在重庆市汇美大厦工程中采用逆作法施工,结合山地城市特点,采用桩柱合一的中间支撑形式,取代传统的型钢中间支撑柱,提出了以现浇混凝土结构柱作为中间支承柱的逆作法施工工艺,并对各主要部位和构件的施工方法作了阐述,确保了工程施工质量和周边环境的安全。

In Chongqing Huimei Mansion project, according to the characteristic of mountainous city, the reverse method was used, which used the intermediate bracing forms of pile and column combing to replace the traditional shaped-stecl column. This article introduced put forth the construction technology of using cast-in-situ concrete structure column as the intermediate bracing column, and the construction method of the main parts and members to ensure the project quality and environmental safety.
