基于顶模状态下水平楼板分段式施工方法的研究与应用

Research & Application Horizontal Floor Segmented Construction Method Based on the State Under the Top Mold

250m以上超高层建筑往往采用筒体结构,而其施工工艺往往采用顶模或爬模体系,即核心筒墙体竖向结构先行施工,楼板等水平结构滞后施工。而水平结构具有测量放线、泵管拆装操作面、逃生通道、水平防护的重要作用,如何在确保核心筒进度及时有规划地插入水平结构施工是研究的主要内容。

250 meters and over high-rise buildings are often used tube structure,and its construction process is often used jacking formwork system,the vertical structure of the core tube wall leading construction,floor and other horizontal structure lagging construction. The level floor has Surveying tubing disassembly operation plane,escape routes,an important role in the level of protection,the paper studies on how to ensure the timely progress of the core tube inserted into the structure planned level of construction.
