基于整体顶升平台施工条件下超高层核心筒钢筋施工技术

Construction Technology of Core Tube Reinforcement of Super Tall Building Based on Integral Lifting Platform Construction Conditions

结合天津周大福金融中心工程核心筒结构自身特点,针对采用整体顶升平台施工核心筒墙体时所面临的竖向筒体与筒内外水平结构错台流水施工、钢筋施工作业面位于平台中下部且平台桁架阻挡钢筋下运、钢筋遇墙内钢结构连接处理等问题,提出钢筋快速安全运输就位、不同部位钢筋预留连接、先套箍法安装等措施,取得较好经济效益和社会效益。

Combined with the characteristics of the core tube structure of Tianjin CTF Financial Center project,this paper puts forward some measures,such as the vertical cylinder and the inner and outer horizontal structure of the construction core wall,the lower part of the steel reinforcement construction working face,the steel structure connection between the platform truss and the wall,such as the rapid and safe transportation in place,different reinforcement connection of different parts,the installation of hoop method,and so on,good economic and social benefits are achieved.
