The invention discloses a construction method of a large-span suspended truss. The construction method comprises the following steps: S1, preparation before installation; s2, assembling the segmented trusses; s3, a temporary supporting device is arranged; s4, mounting the segmented trusses, the secondary trusses and the steel beams; s5, dismantling the temporary supporting device; installation of the orthogonal truss is achieved through the steps, the hoisting problem of the large-span orthogonal truss structure in the construction process is solved, the stability of the structures of all parts in the construction process is guaranteed through the construction method, the construction efficiency is improved, and the construction progress is promoted. 本发明公开了一种大跨度悬空桁架的施工方法，包括如下步骤：S1、安装前准备；S2、拼装分段桁架；S3、设置临时支撑装置；S4、分段桁架、次桁架及钢梁安装；S5、临时支撑装置的拆除；通过以上步骤实现正交桁架的安装，解决了大跨度正交桁架结构在施工中吊装的问题，并且此施工方法保证在施工过程中各部分结构的稳定性，提高施工效率，推进施工进程。
