基于变形协调控制的超高钢连廊整体提升施工技术研究

Research on Overall Lifting Construction Technology of Ultra-high Steel Corridor Based on Deformation Coordination Control

结合工程实例,针对超高钢连廊的幕墙造型龙骨、底部铝板吊顶等附属结构,采用一体化同步提升技术。裙房屋顶拼装时,通过柱顶设置贝雷梁进行荷载转换,减少对混凝土结构的加固措施。通过堆载试验、有限元分析等技术措施,对各工况下的吊顶铝板变形进行分析。优化附属结构与钢桁架连接方式,让更多幕墙附属结构能随钢连廊主体结构同步提升,减少后续高空作业。

Combined with engineering examples,for ultra-high steel corridor curtain wall modeling keel,bottom aluminum plate ceiling and other ancillary structures,innovative integration synchronous lifting technology.When the roof of the skirt building is assembled,the load transfer is carried out by installing Beret beams on the top of the column to reduce the reinforcement measures for the concrete structure.Through the technical measures such as load test and finite element analysis,the deformation of aluminum plate under the working condition is analyzed.Optimize the connection between the accessory structure and the steel truss,so that more curtain wall accessory structures can be lifted simultaneously with the main structure of the steel corridor,reducing subsequent high-altitude work.
