Description

Fastener for steel structure connection

Technical Field

The invention relates to the technical field of fasteners, in particular to a fastener for steel structure connection.

Background

In the steel structure building, we often see the 'lacing wire', the arrangement of the lacing wire is to keep the rigidity of the beam framework, and the diameter and the distance between the waist rib and the lacing wire need to consider the load effect in the construction. When the concrete beam is very high, the high and large reinforcement cage bears the self weight of the reinforcement, and particularly, the load of construction machines, constructors and construction materials in construction can cause the displacement and deformation of the reinforcement cage, so that the dimension displacement of the reinforcement is caused, the bonding force between the reinforcement and the concrete can be influenced, the thickness of a protective layer is reduced, and the durability of the beam is influenced. The appropriate amount of the waist bars and the tie bars are arranged and bound with the stirrups in the steel reinforcement framework to form a whole, so that the deformation of the steel reinforcement framework is effectively restrained, and the rigidity and the stability of the steel reinforcement framework are increased.

However, the tie bar is usually made of a thin steel bar, and both ends of the tie bar are provided with threads and fixed by nuts, and the tie bar has poor fastening performance, cannot tighten the beam framework completely, and is inconvenient to install.
