What Is Rebar Coupler?
A rebar coupler is a mechanical device used to connect two steel reinforcing bars (rebars) end-to-end, creating a continuous length of reinforcement without the need for lap splicing.
Why It Is use?
Purpose: Joins rebars to transfer tensile, compressive, and shear forces effectively.
Material: Usually made from high-strength steel.
Types Of Rebar Coupler?
1.Threaded coupler – rebar ends are threaded and screwed into the coupler.
2.Tapered thread coupler – uses a tapered thread for easy installation.
3.Swaged coupler – coupler is pressed onto the rebar ends.
4.Grout-filled coupler – uses grout or epoxy inside the sleeve.
Advantages of Rebar Coupler :
1.Reduces steel wastage.
2.Avoids congestion in reinforcement.
3.Saves time compared to lap splicing.
4.Maintains full tensile strength of the bar.
