Compression-resistant structure of large-span tent

The invention belongs to the technical field of tents, and particularly relates to a compression-resistant structure of a large-span tent, which is applied to transverse and longitudinal support of the large-span tent with a frame structure and comprises a framework, a connecting framework and a middle column. The middle columns are of columnar structures, and pressure bearing parts are arranged at the upper ends and the lower ends of the middle columns; the number of the frameworks is at least six, each framework is of a rod-shaped structure, the first ends of three of the frameworks are detachably connected with one middle column, the first ends of the other three frameworks are detachably connected with the other middle column, and the end face of the first end of each framework abuts against the edge of the corresponding pressure bearing part; the connecting framework is of a rod-shaped structure, and the two ends of the connecting framework are detachably connected with the two middle columns respectivel
