Construction Technology of Large Steel Connecting Bridge in Kunming New Airport Terminal

介绍昆明新机场航站楼大型钢连桥的分段、拼装方法,通过设置临时支撑胎架解决一次无法吊装就位的施工难题,并阐述大型钢梁的焊接顺序及工艺、高强螺栓的安装和压型钢板的安装。实践证明,对于此种吨位大、吊装空隙小的钢连桥工程,可以通过分段跨外吊装很好地解决。

Authors introduce the segment and assembly about large steel connecting bridge in Kunming New Airport Terminal,and solve the construction problem of hoisting to the correct position by setting temporary supporting jig.The order and technique of welding,installation of the high-strength bolt and the profiled steel sheeting are outlined.For the steel connecting bridge with large size and little hoisting interspace,a good solution can be gained hoisting by segments in the outside of spans.
