High-safety torsion-resistant steel structure truss

The invention discloses a high-safety torsion-resistant steel structure truss in the technical field of trusses. A transverse truss; a diagonal truss; first bolts connected with the vertical trusses and the transverse trusses are arranged at the two ends of the inclined trusses correspondingly; insertion blocks penetrating through the vertical truss are evenly arranged on the left side of the transverse truss, and second bolts fixedly connected with the vertical truss through threads are arranged on the insertion blocks. Limiting plates are connected to the two sides of the top and the bottom of the inserting block in an attached mode, and the limiting plates are connected with the vertical trusses. The insertion block can be vertically limited through the limiting plate, and then fixation of the insertion block can be improved through the first screw; through a rotating rod and a screw II, the fixation of the insertion block can be further improved, so that the fixing effect of the vertical truss and the tra
