塔楼核心筒伸臂桁架层施工关键技术
|
摘要
以南京金鹰项目3塔连体建筑为例,针对其核心筒钢平台与伸臂桁架层结构冲突的问题,通过分析塔楼核心筒伸臂桁架层质量巨大且需在高空施工的难点,设计了合理的施工总体流程,具体阐述了伸臂桁架层安装施工的方案,实现了核心筒钢平台与伸臂桁架层的协调施工。
Taking the 3-tower conjoined building of Nanjing Golden Eagle Project as an example, aiming at the conflict between the steel platform of core tube and the outrigger truss structure, the reasonable overall construction process was designed by analyzing the difficulties in the high altitude construction of the truss layer which is of a large mass in the tower core tube. The scheme of installation and construction of the outrigger truss layer was elaborated in detail, and the coordinated construction of the core tube platform and the outrigger truss layer was realized.
