Mechanical Couplers for Reinforcement Bars
Threaded rebar coupler, also known as the names rebar connectors, rebar splicing, or mechanical rebar couplers is a joint of steel bars on a parallel line that is designed for reinforcement bars and is usually used in conjunction with a rebar threading machine. The thread rebar with an internal thread corresponding to the thread is a mechanical rebar coupler used to transfer the axial tension or pressure of reinforcement. Its diameter is strictly designed by the internationally commonly used types of rebar which applies to the different diameters of the steel bar connection requirements. The threaded rebar coupler with diameters of 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, and 32mm can be produced in YG.

Mechanical Splicing Method of Threaded Rebar Coupler
First, the longitudinal and transverse ribs of the end of the steel bar need to be peeled off by a rebar thread rolling machine. Then they can be rolled straight into ordinary thread and connected with special threaded rebar couplers to form the connection of rebar. Because of the high efficiency, convenience, the fast construction method of rib stripping straight screw connection technology, it has been favored by generation construction organizations. Meanwhile, the technology can also save energy, reduce steel consumption, improve efficiency, and make the connection more stable and reliable. However, there is something you need to note when using technology. The standard value of the tensile strength of the threaded rebar coupler shouldn’t be less than 1.1 times of tensile strength of connected rebars and the standard value of the tensile yield strength shouldn’t be less than the standard value of the tensile yield strength of the connected reinforcement.
The Outstanding Features of Mechanical Rebar Couplers in Our Company:
Reliable Quality. Use the International 45 steel and seamless steel pipe as raw material that its mechanical properties, the chemical composition is by the standard of GB/T600, GB/T8162. It also should conform to the relevant or industrial standards and be confirmed by type test.
In line with international standards. Our products have been tested by the National Construction Project Quality Supervision and Inspection Center and can reach the sub-standard of Level I in GJ107-2010.
Complete specifications and sizes. The standard type, front, and back thread type, and the reduced diameter type can meet the needs of connecting steel bars for the same diameter, reducing the diameter and adjustable length and direction of vertical and inclined parts in the building structure.
Good mechanical performance and reliable connection. As the end of the steel treated by cooling is formed by rolling, both thread and steel strength are improved which makes up for the effect of the diameter of the thread being baseless than the diameter of the base circle on the strength weakening. The joint strength is higher than the parent material strength which can make the parent material give full play to its strength and ductility.
Convenient connection, construction, and high efficiency. The threaded rebar couplers are prefabricated in the factory. It can be operated flexibly even in a tight arrangement of rebars in a narrow place.
Safety and environmental protection. No welding and open flamework, also no pollution during construction.
Facilitate testing. There is no need to use specific detection equipment during construction. The quality of the joint can be measured only by looking at the exposed steel bar teeth.
Strong applicability. It is suitable for the connection of the reinforcing bars in all aseismic and non-aseismic reinforced concrete structures, as well as suitable for bending reinforcing bars, fixed reinforced bars, steel cages, overlength steel bars, and other places.
