Beschreibung
Zusammenfassung:	The invention provides a construction method of a shell-shaped large-span net rack, and relates to the technical field of high-altitude assembling construction of net shell net racks. Comprising the steps of preparation before installation, plane arrangement and scaffold erection, middle truss erection and ring beam installation, double-layer net rack assembly, fixed hinge support installation, reticulated shell installation and scaffold unloading and dismantling, the high-altitude installation problem is effectively solved, the installation quality is guaranteed, and meanwhile the engineering cost is reduced. 本发明提出了一种贝壳形大跨度网架施工方法，涉及网壳网架高空散拼施工技术领域。包括安装前的准备工作、平面布置及搭设脚手架、搭设中部桁架及安装环梁、拼装双层网架、安装固定铰支座、安装网壳以及卸载拆除脚手架的步骤，其有效解决了高空安装的难题，保证安装质量的同时降低了工程成本。
