深圳平安金融中心总建筑高度为660m,为中国在建第一高楼,其结构设计新颖。根据其楼层建筑功能及楼板受力情况不同,组合楼板采用钢筋桁架楼承板和压型钢板设计,楼板组合形式及节点设计较复杂。根据组合楼板在节点设计和施工上的特殊性,重点介绍了组合楼板深化设计、板边悬挑设计、典型节点设计要点及难点和施工技术,保证施工质量和安全,加快施工进度,提高施工效率。
The total building height of Shenzhen Ping An Financial Center is 660m, which is the tallest building under construction in China. Its structural design is novel. According to the different functions of the floor and the force of the floor, the composite floor adopts the design of the steel truss floor slab and the profiled steel plate, and the combination of the floor slab and the node design is more complex. According to the particularity of composite floor in the design and construction of the joints, this paper mainly introduces the design of combined slab, overhang design of cantilever, the design of typical joints and the difficulties and construction techniques to ensure the construction quality and safety, speed up the construction progress and improve the construction efficiency .
