摘　　要：某机场维修机库采用三层斜放四角锥网架结构,施工前对高空散拼、地面拼装、分片吊装等4种方案进行比较,最后选定(1)地面组拼、整体提升;(2)高空散拼;(3)地面分段组拼、高空对接;(4)高空合龙的综合安装方法,介绍网架组拼顺序、拼装方法、整体提升、合龙及卸载等关键施工技术,实践证明,该工艺切实可行。The service hangar in an airport adopted three layers of oblique quadrangular pyramid grid structure. High altitude assembly, ground assembly and lifting were compared with other before construction, and a combined installation method was finally determined, including （1） ground assembly and integral lifting; （2） high altitude assembly; （3） ground partial assembly and high altitude connection; （4） high altitude closing. Key construction techniques were introduced, such as grid frame assembly sequence, assembly method, integral lifting, closing and unloading, etc. It was proved that this technical process is feasible and efficient.
