钢结构架空连廊“四绳”分体吊装法施工技术

Construction Technology of Four-rope Partial Lifting Method for Spatial Steel Corridors

为了解决某大型医院新建病房楼与老病房楼之间的交通联系问题,并最大限度地满足建筑立面造型的美观,在新老病房楼3个不同高度处共设置了6道钢结构架空连廊。为解决钢结构架空连廊的吊装问题,提出了"四绳"分体吊装法施工技术,通过钢结构深化设计,将连廊拆分为钢构件并确定吊点位置,采用四绳吊装法起吊,缩减了施工工序,吊装效果较好,为类似工程的吊装施工提供了参考依据。

In order to solve traffic connection problems between the newly-built ward building and the old ward building in certain large scale hospital and obtain a beautiful building elevation form to the greatest extent,six spatial steel corridors were set at three different heights of new and old ward buildings. In order to solve lifting problems of spatial steel corridors,the construction technology of four-rope partial lifting method was proposed. By mean of detailed design of steel structure,the corridor was split into many steel members and lifting points were also determined,then the steel members were lifted to use four-rope lifting method. The method simplified construction procedures and lifting effect was better,which can provide reference basis for lifting construction of similar projects.
