上海浦东国际机场航站楼特大型斜挑悬索拱形钢屋盖安装工艺及设备的研究

Study On Installation Technology and Devices Adopted For Extra-Large Slantingly Overhanging Suspended cable Arched Roof Used In Air Terminal of Shanghai Pudong InternationalAirport

本工程的特大型斜挑悬索拱形钢屋盖为国内外罕见,经过多方案的研究比较和优化,采用“屋架节间地面拼装,柱梁屋盖跨端组合,区段整体纵向移位”和“地面组装,四机抬吊,高位负荷,远程吊运”的技术路线,完成了航站楼和登机长廊的屋盖安装。

Extra large slantingly overhanging suspended-Cable arched steel roof adopted in this project is rarely seen at home and abrood. After multiway research and optimization,roof installation of air terminal and boarding corridor is finished by the adoption of 'assemblage of roof components on ground, roof-span-end combination of column and beam, integral vertical relocation of sections' and 'assemblage on ground, lifting by four hoisting devices, Load-bearing at higher level, hoisting and transporting at long distance'.
