摘　　要：首都机场A380机库大厅屋盖钢结构长352.6m,宽114.5m,建筑面积40372.7m2,建成后可同时容纳4架空客A380飞机,为世界第一大机库,也是目前世界上最大的焊接球网架。由于整个钢网架的吨位重、跨度大,所以,对钢网架的加工制作精度方面要求非常严格。通过制定详细的加工计划,使现场安装误差在10mm以内;着重考虑了时间紧、任务重、精度高等因素,保证了焊接球的加工质量和焊接质量,提高了精度,大大减少了损耗。Lobby roof of Capital Airport A380 aircraft hangar is 352.6 m long and 114.5 m wide, and its floor area is 40372.7m^2. After completion, this aircraft hangar, which is able to hold four pieces of A380 passenger planes, will be the largest one in the world and adopts the largest welded spheric space frame. Due to the high tonnage and large span of the whole steel space frame, process and fabrication of the steel space frame shall be strictly orecise.
