北京银泰中心工程为超高层建筑,其塔式起重机采用分区域、分时间的设置方法,即不同施工单位按区域自行布置、整体协调的方式。结合工程实际条件,介绍了其中3台塔式起重机的选择原则、选型、布置、定位、附着及其基础设计等关键技术。实践证明,该群塔技术能够达到工期和成本的有效结合,获得良好的综合效益。 Beijing Yintai Center project is a super high-rise building whose tower cranes adopt sub-regional and sub-time setting methods, that is, different construction units arrange themselves by region and coordinate with each other. Combined with the actual engineering conditions, the paper introduces the selection principle, selection, arrangement, positioning, attachment and basic design of the three tower cranes. Practice has proved that the group tower technology can achieve the effective combination of construction period and cost, get a good comprehensive benefit.
