摘要
建筑下部有地下室同时场地狭窄,起重机械无法行走的情况下,普通的吊装施工方法无法完成大型钢桁架的吊装。针对体育馆的结构形式,在已完成的梁顶面上铺设无支撑的滑轨,进行高空滑移安装钢桁架。在滑移过程中通过监控保证滑移的同步进行,在落位处滑轨断开保证桁架顺利落位。
Construction plant with basement and narrow working plane makes the ordinary hoisting construction of steel truss powerless. In the installation process of steel truss of gymnasium, the steel trusses are slipped on the rail set on the top of beam. The sliding process is monitored to ensure synchronized. The rail is disconnected in the instal- lation location to position the steel truss.
