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.
