摘要
中国国家博物馆改扩建工程中大型钢结构桁架屋面安装,由于钢结构桁架重量重、跨度大、高程高、施工难度大等特点,采用钢结构桁架累积滑移的施工技术,成功解决了钢结构桁架安装过程中的重点、难点问题,节省了资金,减少了安全隐患。采用该方法施工,质量可靠,同时可缩短工期、降低成本,取得了良好的社会和经济效益。
It is the project for Chinese Country Museum expansion project of large steel truss roof installation.Due to steel structure truss heavy weight,high elevation,difficult in construction,the steel truss accumulative construction technology of slipping installation is used.The key and difficult point of the steel structure truss installation are resolved by cumulative slip technology,it could save money,reduce hidden danger,guarantee quality,shorten the construction period,and reduce the cost,and achieved good social and economic benefits.
