摘要
高层核心筒因无爬架而无法施工,导致外钢框架钢梁连接核心筒时无受力点,也无法施工,影响整个项目的工期。为解决上述问题,研发一种高层钢框架-混凝土核心筒同步等高攀升施工技术,在核心筒周围设置支撑体系,作为核心筒未施工时的钢梁受力点,将外框钢结构独立成全钢结构形式,实现外围钢框架与核心筒同步施工,外围楼板与核心筒墙柱同步浇筑。
The high-rise core tube can not be constructed because there is no climbing frame.As a result,when the steel beam with outer steel frame is connected to the core tube,there is no stress point and can not be constructed,which affects the construction period of the entire project.In order to solve the abovementioned problems,a high-rise steel frame-concrete core tube synchronous contour climbing construction technology is introduced.A support system is set around the core tube as the stress point of the steel beam when the core tube is not constructed,and the outer frame steel structure is independently made into a full-steel structure.The form realizes the simultaneous construction of the outer steel frame and the core tube,and the simultaneous pouring of the outer floor slab and the wall columns of the core tube.
