Mechanical Couplers For Reinforcement Steel Cold Extruded Oiled Surface 2.5mm Pitch

Reinforcing steel mechanical cold extrusion press steel joint sleeve

product description:

Rebar stripping and rolling straight thread connection is a new type of steel connection sleeve technology. The structural principle is to strip off a part of the longitudinal ribs and transverse ribs at both ends of the steel bars to be connected, and then directly roll them into ordinary straight bars. After threading, it is connected with a special straight threaded steel connecting sleeve. Form a steel connection.

advantage:

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.

3. Convenient inspection: No special inspection equipment is needed during the construction process, and the quality of the joint can only be determined by observing the teeth of the exposed steel bars. Strong applicability: It is suitable for steel connections of all seismic and non-seismic reinforced concrete structures, as well as for bending steel bars, fixed steel bars, steel cages, extra-long steel bars and other occasions that cannot be rotated.

application:

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. The straight threaded sleeve connection is convenient, fast and simple, construction does not require electricity, weatherproof, and can be constructed all-weather.
3. It can connect horizontal, vertical and inclined HRB335, HRB400 steel bars with the same or different diameters.
4. Good anti-low temperature effect, passing the low temperature test of minus 40 degrees.
