Description

Technical Field

[0001] The utility model relates to the technical field of trusses, in particular to a movable truss. Background Art

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

[0003] In the Chinese patent with publication number CN209665360U, a movable truss is mentioned. The truss body adopts a triangular support structure, which ensures the load-bearing capacity while reducing the raw material matching and reducing the cost. The movable truss provided by the utility model is also equipped with rollers, which can move the truss back and forth; however, the rollers on the truss are directly fixed thereon, which is not convenient for rapid installation and disassembly of the rollers, cannot meet actual use requirements, and also affects the normal use of the truss. In addition, the truss is not stable enough during the movement, which reduces the practicality. Therefore, we introduce a movable truss. Utility Model Content
