首都机场306米×90米四机位飞机库是当今世界最大的机库,跨内无任何支柱,同时可容纳4架 B747飞机维修。该工程由北京建工集团与德国B+B 公司联合承建。中国航空工业规划设计研究院与德国 B+B 公司设计,德国人监理。屋盖钢结构由双跨连续悬挑栓焊钢桥、中梁桁架与多层四角锥焊接球管网架组成。其特点是跨度大,达153米,面积大,承受动荷载,钢构件重,节点类型多,结构复杂,技术标准高,施工难度大。钢结构于1995年10月完工,1996年11月,国家验收为优良。
The Capital Airport’s 306-meter by 90-meter four-position hangar is the largest hangar in the world today. It has no pillars and can accommodate 4 B747 aircrafts for maintenance. This project was jointly constructed by Beijing Construction Engineering Group and German B+B company. China Aviation Industry Planning and Design Institute and German B+B company design, German supervision. The steel structure of the roof consists of a double span continuous cantilever welded steel bridge, a mid-beam truss, and a multi-layered square-taper welded ball tube grid. Its characteristics are large span, up to 153 meters, large area, dynamic load, heavy steel components, many types of nodes, complex structure, high technical standards, and difficult construction. The steel structure was completed in October 1995. In November 1996, the national acceptance was excellent.
