摘　　要：某电梯试验塔工程顶层大悬挑圆弧形钢筋混凝土结构施工平台搭设时,采用悬挑式型钢支撑平台作为承力平台,上部混凝土结构施工采用扣件式满堂支撑模板体系,同时以此处外墙脚手架体系作为安全围护及操作架,两者共用该悬挑型钢承力平台。设计计算的数据与施工监测数据可较好吻合,表明了该设计计算模型和方法的正确性。Cantilever section steel supporting platform is adopted as bearing structure for construction platform of super-span cantilever circular-arc concrete structure on the top storey of a certain elevator experimental tower building. When constructing the upper part concrete structure, the fastener steel tube full hall formwork support shuttering is used, the steel tubular scaffold with couplers is used as the safeguard structure and the operating platform. The fastener steel tube full hall formwork support shuttering and the steel tubular scaffold with couplers are both based on the cantilever section steel supporting platform. The construction monitoring data matches well with the theoretical value which indicates that the calculation model and method are accurate.
