摘　　要：北京绿地中心4号商务办公楼工程建筑高度达260 m,在42,43层设有桁架转换层。通过应用Takla软件与BIM技术相结合的方式进行桁架层钢构件的深化设计,并在工厂进行了桁架层的预拼装。桁架层超重构件创新采用滑移钢平台措施进行吊装,对钢筋连接采取了优化措施,解决了桁架转换层结构复杂、施工困难的问题,确保了桁架层的整体施工进度与质量。Beijing Greenland Center No.4 office building construction reaching a height of 260 m, with truss transfer layer In 42 and 43 layer, the application of Takla and BIM a combination of technologies for deepening the design truss of steel member, and in processing plants was truss-pre assembled.The truss layer overweight component using slip steel platform innovation measures for lifting. Optimized measures against rebar connecting. Solve truss transfer storey structure was complex and difficult problems of construction, ensures the overall construction schedule and quality of trusses.
