摘　　要：以重庆某大型综合体项目45 m跨度三角形钢管桁架结构安装为例,针对施工场地特殊、吊装设备偏小的实际施工条件,经综合考虑,采用了"滑移胎架+塔吊精确定位吊装"的施工方法,并从工艺原理和关键技术流程角度,对施工方案进行了详细阐述。经实践,该技术安全可靠,可为类似工程参考借鉴。Taking the installation of a 45 m large-span triangular steel truss of one large complex project in Chongqing as an example, and aiming at its special construction site and actual construction condition of smaller lifting equipment, one construction method by using gliding bed-jig and tower crane accurate positioning of hoisting was adopted after overall consideration. This paper also elaborates in detail the construction scheme from viewpoints of technical principle and key technical process. According to practice, such technology is safe, reliable, and can provide references for similar projects.
