Manufacturing of structural steel connectors for cold-extruded pressure rebar connectors

product description:

Rebar sleeve is also called rebar joint: a connector used to connect rebar, and its internal thread corresponds to the thread of the thread.

The advantages of this connection method are as follows:

1. Good mechanical properties and safe connection: Because the end of the steel bar is formed by rolling and the material of the steel bar is cold worked, the strength of the thread and the steel bar is improved, and the weak point is made up for. The strength of the thread base diameter is less than the diameter of the steel bar base circle. The influence of the joint strength of the connection is greater than the strength of the base material, which can make the base material fully exert its strength and ductility.

2. Convenient connection: In narrow places, it can be flexibly operated in densely arranged steel bars. Convenient construction and high efficiency: The steel connecting sleeve is prefabricated in the factory. Quality assurance: The on-site thread rolling head equipment can process nearly 400 joints per shift, which has unparalleled advantages in the construction of large-scale projects and basement slabs. , There is no pollution during the construction process, no open flame operation, safe and environmentally friendly, and can be constructed all-weather.

Application of steel sleeve:

1. The use of steel connecting sleeves in the construction engineering industry can greatly reduce the use of materials, and the operation is simple, and it is not limited by the type of steel components.
2. It can connect horizontal, vertical and inclined HRB335, HRB400 steel bars with the same or different diameters.
