Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to an assembled steel structure truss. Background Art

[0002] A truss is a structure made of rods connected to each other at both ends with hinges. A truss is a plane or space structure composed of straight rods, generally with triangular units. Truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials, reduce deadweight and increase rigidity compared to solid beams.

[0003] In the truss field, existing trusses are all integral, and are easily collided during transportation and use. When a single rod of the truss is damaged by a collision, it is not easy to replace it. In addition, the width and height of the truss cannot be adjusted according to the situation in a narrow space, resulting in inflexible use of the truss. Utility Model Content
