摘要
北投大厦工程地上采用钢框架+屈曲约束支撑的结构形式,内中庭周围设计有16根内倾5.83°的斜钢柱,通过采用手工葫芦三点吊装内倾钢结构斜柱,实现对内倾钢结构斜柱的快速位置调节和精确安装,利用卡板临时固定,焊缝打底后塔式起重机脱钩,可为类似项目钢结构施工提供参考。
A combination of steel frame+buckling restrained brace is applied on the project site of Beitou Building.There are 16 external inclined steel columns(5.83°)along the periphery of the inner atrium,which are hoisted at three points by a hand-operated hoist to facilitate fast location adjustment and accurate installation.Internal inclined columns are decoupled from the hook of the tower crane used after the temporary use of fixtures and bottoming by welding,as a reference for construction of steel structures in similar projects.
