摘要
安福大厦工程为一个集办公、酒店、商业为一体的大型多功能综合性建筑,根据设计图纸要求在西北角(①/M轴)从2层至16层设置长度11.1m混凝土悬挑板,但4层至15层隔层挑板用德国PFEIFER制造PV360全封闭钢索斜拉。为实现钢索施加预应力后平衡结构板自重,通过周密精心的施工组织安排,采取优化的悬挑支撑、切实可行的预埋件安装措施和张拉工艺的严格控制等一系列措施,确保了混凝土结构的安全使用要求,也进一步提出了钢索斜拉混凝土板的一些关键技术。
The Anfu building project is a collection work, the hotel, the trade is a body large-scale multipurpose comprehensive construction, （the 1/M axis） hangs the bridging piece according to the design paper request in the northwest corner from two to 15 establishment length 11.1m concrete, but make the PV360 entire seal steel wire four to 15 insulation bridging pieces with German PFEIFER to hang pulls.In order to realize the steel wire infliction pre-stressed back balance structure board dead weight, arranges through the thorough careful construction organization; to adopt the optimization to hang selects the support, practical and feasible buries to install the measure and in advance pulis the craft the strict control and so on a series of measures, has guaranteed the concrete structure safety handling request, also further proposed the steel wire hangs pulls the concrete slab some key technologies.
