Description

Technical Field

[0001] The utility model relates to the technical field of steel bar trusses, in particular to a steel bar truss with high strength and earthquake resistance. Background Art

[0002] The upper and lower chord steel bars and the web steel bars in the steel truss form a stable triangular structure that can effectively withstand the bending moment of structures such as floor slabs or roofs.

[0003] A Chinese patent application, publication number CN 216007475 U, discovered an adjustable steel truss floor deck node. The node comprises a load-bearing beam, one side of the upper end of which is welded to a floor deck truss, and the other side of the upper end of which is welded to a riser or dropper truss. The floor deck truss, riser or dropper truss, are each provided with a plurality of distribution bars welded to the floor deck truss, the riser or dropper truss, and the dropper truss. Concrete is provided at the floor deck truss, the riser or dropper truss, and the dropper truss. The structure is simple, saves steel, provides good structural stability, and increases construction efficiency. This solution eliminates the problem of heavy welding workload and improves ease of construction and installation.

[0004] The web reinforcement of existing steel trusses is usually adjusted in an overall manner, rather than by adaptively adjusting the distance between a single set of upper and lower chord reinforcements. This results in low adjustment accuracy and is unable to flexibly respond to slight deformations or construction errors of the building structure, resulting in limitations during use. Therefore, it is necessary to provide a steel truss that can adaptively adjust the distance between the upper and lower chord reinforcements to cope with slight deformations or construction errors of the building structure.
