摘要
超高层建筑多设计为框架核心筒结构,主要采用爬模或顶模体系进行施工,筒内水平楼板结构往往滞后剪力墙施工。结合重庆国金中心T1塔楼,主要介绍了核心筒水平楼板采用钢梁、压型钢板组合结构代替原有混凝土水平结构进行分段式施工,创新了钢结构吊装施工方法,优化预埋套筒接驳器,取得了良好的实际效果。
The tall building is designed as the frame core tube structure,which is mainly used for climbing formwork or top formwork system. This paper combines the T1 tower King Center in Chongqing,mainly introduces the core level of the floors of girder and profiled steel sheet concrete composite structure to replace the original level structure of sectional construction,innovation of the hoisting construction method of steel structure,optimization of pre buried sleeve connector,and achieved good effect.
