Large-span diagonal member truss and mounting method thereof

The invention relates to a large-span diagonal draw bar truss which comprises an upper-layer truss and a lower-layer truss, a plurality of reinforcing rods are connected between the upper-layer truss and the lower-layer truss, and lifting lugs are arranged at the joints of the reinforcing rods and the lower-layer truss. The truss is ingenious in structure, construction conditions are improved, working efficiency is improved, risks in the installation process are reduced, and popularization and application of the truss in the technical field of building construction are facilitated. The installation method of the large-span diagonal draw bar truss is used for installing the large-span diagonal draw bar truss, effectively solves the construction problems that a conventional truss needs large mechanical equipment and a large number of supporting frames to be hoisted, works aloft and the like, greatly reduces the consumption of manpower, materials, equipment and the like caused by segmented hoisting and high bulk
