北投大厦大跨度钢桁架综合施工技术

COMPREHENSIVE CONSTRUCTION TECHNOLOGY FOR LARGE-SPAN STEEL TRUSS IN BEITOU BUILDING

北投大厦工程大跨度钢桁架数量多、分布广,通过将临时格构式支撑运用在中庭实腹桁架、入口空腹桁架以及西南悬挑弧形桁架,所有构件的安装均采用高空原位散拼的方式,实现钢构件的精确定位与安装,可为类似项目钢结构施工提供参考。

Beitou Building involves a number of distributed large-span steel trusses.With temporary lattice supports for solid web trusses of the atrium,open web trusses of the entrance and cantilevered arc trusses of the southwest,all members are distributed in situ at high altitudes.Therefore,steel members are located and installed accurately,which provide a reference for steel structure construction in similar projects.
