Threaded Rebar Couplers

Threading the Rebar Ends 

The ends of the rebars are machined to create threads, typically using a rebar threading machine.

Aligning the Bars

The rebars are positioned in line with each other.

Screwing the Coupler

The coupler is screwed onto one rebar, and then the other bar is threaded into the opposite side of the coupler until both are tight and secure.

Ensuring Tightness

In some cases, torque wrenches are used to ensure the correct tightness, providing maximum strength and performance.

Superior Structural Integrity

The direct steel-to-steel connection provides a robust load transfer, enhancing overall structural performance.

Reduced Rebar Usage 

No overlap means less steel is needed, lowering material costs.

Faster Construction

Threaded couplers allow for quicker assembly and installation, helping projects stay on schedule.

Space Efficiency

Ideal for congested reinforcement areas in high-rise buildings, bridges, and complex concrete elements.

Better Seismic Resistance

Offers continuous reinforcement, which improves stability during earthquakes.

Adaptability

Suitable for different diameters and grades of rebar, making them versatile for a range of projects.

Step 1: Prepare the Rebar

• Cut the rebar ends square to ensure a proper fit.

• Remove any rust, dirt, or oil from the surface.

Step 2: Thread the Rebar Ends

• Use a threading machine to cut the threads according to the coupler specifications.

Step 3: Install the Coupler

• Screw the coupler onto the first rebar end.

• Align the second rebar and screw it into the coupler.

Step 4: Tighten the Connection

• Use the recommended torque to ensure a secure joint.

Step 5: Inspect

• Visually check the alignment and tightness before pouring concrete.

High-rise buildings

For vertical and horizontal reinforcement continuity.

Bridges and flyovers

To handle high tensile loads.

Industrial structures

Where heavy-duty reinforcement is essential.

Seismic zones

To improve earthquake resistance.

Prefabricated construction

For easy assembly of pre-cast elements.

Steel Usage

• Threaded Rebar Couplers: Use less steel, reducing material costs.
• Lap Splicing: Requires more steel due to overlapping, increasing costs.

Space Requirement

• Threaded Rebar Couplers: Take up minimal space, ideal for congested areas.
• Lap Splicing: Needs more room due to bar overlap, which can cause congestion.

Installation Speed

• Threaded Rebar Couplers: Faster to install, helping speed up construction timelines.
• Lap Splicing: Slower process due to the need for precise overlaps and alignment.

Seismic Performance

• Threaded Rebar Couplers: Provide excellent resistance to seismic forces with a continuous load path.

• Lap Splicing: Offers only average performance in seismic zones.

Structural Integrity

• Threaded Rebar Couplers: Deliver high structural strength through direct bar-to-bar connection.

• Lap Splicing: Offers moderate integrity due to reliance on overlapping lengths.
