摘要
南京中国移动通信综合楼和附楼之间的连廊,采用一端简支、一端滑动的钢结构桁架体系。结构跨度为47m,总重约为170t。施工采用"地面拼装,整体提升"的安装方法,通过滑动支座端的临时锚固作为整体提升牛腿,同时,基于方案设计及相关验算工作,成功实施了该工程重、大钢连廊快速提升就位。
Abstract ：The gallery connecting complex building and affiliated building of China Mobile Building in Nanjing adopts steel truss structure with a simple supported end and the other sliding end which has 47m span and weight of 170t. A general construction plan of ground assembly and integral lifting is established. The design and checking calculation is described. The problem of temporary fixation of sliding support as lifting corbel is solved. The lifting work of heavy and large steel gallery is completed successfully.
