摘　　要：大连国际会议中心悬挑桁架安装施工过程中,为降低临时支撑反力、减小支撑拆除时的卸载吨位,同时避免周边悬挑桁架上组合楼板混凝土在支撑拆除时由于桁架下挠变形而开裂,采取组合楼板及建筑构造面层在支撑拆除后进行施工的方案。在平台桁架吊装、结构合龙、现场质量控制及支撑拆除等方面采取了相应的技术措施,满足了施工质量要求。During installation of suspension truss in Dalian International Conference Center project, composite floor and structural layers of building are construction after support structures are dismantled, with the purposes to reduce counterforce of temporary support and unloading tonnage in dismantlement of support and to avoid crack caused on concrete of composite floor on surrounding suspension truss due to down-warping deformation of truss. Relevant technic, al measures quality control and dismantlement of support, and are adopted for lifting of platform truss, structure closure, fieht construction quality requirements are successfully satisfied.
