超高层建筑核心筒爬升模架体系选型分析及施工工艺选择
|
摘要
通过对超高层建筑核心筒结构适合先行浇筑施工的施工装备——爬升模架体系构造形式和特点的分析,给出施工选型原则,并根据该原则对核心筒模架施工进行选型分析。爬升模板系统和顶升模板系统是超高层建筑核心筒模架施工的主流装备,在施工安全性能和承载力要求更高的400m以上的超高层建筑结构施工中采用顶升模板系统已成为施工装备的首选。超高层建筑核心筒采用竖向结构与水平结构同时施工工艺具有较大优势,是对施工工期无紧张要求的工程的首选工艺。
Based on the analysis of the structure form and characteristics of climbing formwork system,which is suitable for the construction of core tube structure of super high-rise building,the principle of construction type selection is given,and the type selection of core tube formwork construction is analyzed according to the principle. The climbing formwork system and the jacking formwork system are the mainstream equipment in the construction of core tube formwork frame of super high-rise buildings. The jacking formwork system becomes the preferred equipment in the construction of super high-rise buildings with higher safety performance and higher load requirements. The core tube of super high-rise building adopts the construction technology of vertical structure and horizontal structure at the same time,which has great advantages and is the preferred technology for projects without tight construction period.
