某超高层办公楼悬挑平台施工技术

CONSTRUCTION TECHNOLOGY OF CANTILEVERED PLATFORM IN A SUPER HIGH-RISE OFFICE BUILDING

开发商为满足外观装饰美化或功能性要求,时常在高层建筑设置悬挑结构。悬挑结构外挑出主结构,在空间位置上将会与爬架相互冲突,爬架只能作为操作架和防护架。因此,使用爬架工艺时无法施工混凝土悬挑结构。针对此类问题,从悬挑结构施工的空间布置、实际施工难度、技术难点、安全分险、经济效益等方面,对可行的技术施工方案进行对比讨论,为采用爬架工艺的高层悬挑结构施工提供一些思路。

Developers often set up overhanging structures in high-rise buildings in order to meet the requirements of exterior decoration and beautification or functionality.If the main structure is protruded from the cantilever structure,it will conflict with the climbing frame in the spatial position,and the climbing frame can only be used as an operation frame and a protective frame.Therefore,the concrete cantilever structure cannot be constructed when using the climbing frame process.In view of such problems,this paper will compare and discuss feasible technical construction schemes from the aspects of space layout,actual construction difficulty,technical difficulties,safety and risk separation,and economic benefits of cantilever structure construction.Pick structure construction to provide some ideas.
