Introduction:

Parallel thread roller rebar coupler is a high-performance critical component used for the mechanical splicing of steel reinforcement bars. Manufactured from high-quality alloy structural steel, it employs a rib-peeling and roll-forming process to create high-strength threads on the ends of the rebars. This coupler is then used to join two rebars together, forming a solid and reliable mechanical splice.

The product fully complies with the highest performance requirements (Grade I) for splices as specified in the Chinese National Standard GB/T 1499.2-2018 "Steel for the reinforcement of concrete - Part 2: Hot rolled ribbed bars" and the Industry Standard JGJ 107-2016 "Technical Specification for Mechanical Splicing of Steel Reinforcements". It is the preferred modern construction technology for replacing traditional welding and lap splicing methods.

How to Connected

STEP 1 ：Rib Peeling: A specialized rib-peeling and thread-rolling machine is used to precisely remove the longitudinal and transverse ribs from the ends of the reinforcing bars, forming a smooth and regular cylindrical surface. This step eliminates interference from the ribs during subsequent rolling, ensuring a consistent base diameter.

STEP 2 ：Thread Rolling: The cylindrical section after rib peeling undergoes cold-rolling via thread-rolling wheels. Under plastic deformation, the metal fibers are redistributed and strengthened, forming continuous, dense, high-strength threads. This process does not involve metal cutting but rather enhances the metal's properties.

STEP 3 :Reba coupler Connection: The two reinforcing bars with processed threads are screwed into the sleeve. A specialized wrench is used to tighten them until the bar ends are firmly pressed against each other inside the sleeve, enabling the transfer of force.

Product Advantage:

High Joint Strength: The thread area is strengthened through cold rolling, achieving hardness and tensile strength that exceed those of the base rebar material. This enables connections of equal strength or even superior strength compared to the rebar itself.
Stable Performance: The fully mechanized process minimizes the impact of human factors, ensuring consistently reliable and stable quality.
Pollution-Free: As a cold-working operation, it involves no open flames, no heat-affected zones, and no welding fumes, making it safe and environmentally friendly.
High Construction Efficiency: Rebar ends can be prefabricated in factories. On-site assembly is fast and is not affected by weather conditions.
Material & Energy Saving: It eliminates the need for lap lengths, saving rebar material. The absence of electric welding significantly reduces energy consumption.
