摘　　要：近年来,整体提升技术在网架施工中的应用越来越多,工艺日益趋近成熟。不同工程施工状况,对提升的整体流程又有所不同,川航维修机库因大门桁架与大厅网架最下层存在3.4 m高差,在采用整体提升方案的同时,引入二次提升以及吊点置换技术使网架顺利安装就位。In recent years,the integral lifting technology has been applied more and more in the construction of space truss,and the technology is becoming more and more mature.Different engineering construction conditions have different overall lifting processes.Because there is a 3.4 meter high difference between the gate truss and the bottom floor of the hall grid in the maintenance hangar of Sichuan Airlines,the overall lifting scheme is adopted,and the secondary lifting and lifting point replacement technologies are introduced to make the grid smoothly installed in place.
