施工升降机与液压爬模平台连接在超高层建筑结构施工中的应用

Application of Connection Between Construction Elevator and Hydraulic Climbing Formwork Platform to Super High-Rise Building Structure Construction

北京平安金融中心主楼地上部分采用型钢混凝土柱-钢梁外框-混凝土核心筒结构组成的混合结构体系。考虑到建筑结构形式及施工的实用性与经济性,其核心筒采用液压爬模,且将施工升降机置于核心筒内。通过设计与计算,成功地将施工升降机与液压爬模底平台相连,突破了以往的惯例,极大地方便了施工,为类似超高层建筑工程提供了参考范例。

The above-ground part of the main building of Beijing Ping An Financial Center adopts a mixed structure system which consists of steel reinforced concrete column,steel beam frame and concrete core tube structure. Considering the structural form,the practicability and economy of the construction,the core tube adopts hydraulic climbing formwork and the construction elevator is placed within the core tube.By iterative design and calculation, the construction elevator is successfully connected with the bottom platform of hydraulic climbing formwork,which breaks through the previous'practice,greatly facilitates the construction and provides a reference example for similar super high-rise building projects.
