摘　　要：天津滨海国际机场T2航站楼屋面为钢柱支撑双层双曲面焊接球钢网架形式,最大跨距60m,安装高度达43.7m,整个屋面投影面积达102 050m2,具有造型复杂、面积超大、安装困难、工期紧、体量大等特点。施工中为保证安全、快速、高质地完成,通过对既有的液压提升技术进行改进,采用倾斜网架液压非同步提升翻转施工技术,降低了安全隐患,节约了施工成本,加快了施工进度,解决了大面积复杂造型屋面网架安装难题。The roof of T2 terminal building of Tianjin Binhai International Airport is designed as double hyperbolic welded ball grid supported with steel columns.The large span of roof is 60m.The installation height of the roof is 43.7m.The projected area of integral roof is 102 050m2.The roof is difficult to install because of its super-large area,strict construction time and large quantity.By improving existing hydraulic hoisting technology,the asynchronous hoisting and turnover technology is adopted for the tilted grid.And the installation difficulties of complex shaped roof grid are solved with low safety risk and cost and short construction time.
