大跨度空间管桁架结构施工技术

大跨度空间管桁架结构有着优美的空间形体,这一类结构受力合理、刚度大、重量轻、杆件单一、外形美观,近年来,在我国各省市体育场馆、会展中心等公共建筑中得到广泛应用,如上海洋山港南北闸桥项目、南通体育场、南京新火车站等都是典型的大跨度空间管桁架结构体系.这里以洋山港南北闸桥项目为例,对其加工及安装技术展开研究及探索.

Construction Technology of Large-span Space Pipe Truss

Large-span space pipe truss structure is of beautiful space configuration with reasonable load, high stiffness, light weight, single bar and good appearance. In recent years, this structure has been widely used in many provincial and municipal stadiums, exhibi- tion centers and other public buildings, such as Shanghai Yangshan Port North and South Stone Bridge project, the stadium of Nan- tong, Nanjing railway station etc. which are all the typical large-span space pipe truss structures. Taking Yangshan Port North and South Stone Bridge as an example, the processing and installation technologies are studied and explored.
