Reinforcing bar coupling has all of the features desirable in a rebar joining system combined with unequaled simplicity of installation. Couplers are hollow mechanical structures that are threaded inside and screwed onto two rebars, which are combined to form a mechanical joint. Couplers are designed to splice the same diameter bars where one bar is free to move and can be rotated.

Benefits of using a mechanical rebar connection include:

• A self-aligning, taper-threaded design provides continuity and structural integrity.

• Spliced bars behave as continuous lengths of reinforcing steel bars by providing full strength in tension and compression and stress reversal applications.

• Develops higher tensile strength than lap splicing in reinforced concrete.

Steel is used for the tie of rebars.

Tie wires can keep the reinforcement in place. In the absence of the construction binding wire, the reinforcement can move, leading to an increase in spacing between reinforcement in a particular section and a decrease in another section. This will affect the strength of the structure and can lead to construction failure.

Purpose of Using Tie Wires During Construction

These are used extensively in the construction sector for tying applications. The rebars get tied at the joints to keep the structure intact using binding wires. Binding wires are also referred to as annealed wires. They are subject to the process of annealing to make them flexible and soft for tying. The annealed wire construction is done using wires of different diameters ranging from 0.61 mm to 0.91 mm. To use binding wires during construction, it requires these wires to be flexible and robust. They should be flexible enough to tie and strong enough to hold a joint.

• Maintain the location and direction of steel bars.

• Hold the lapped bars in position.

• Secure space bars and chairs in place.

• Help in other construction-related work.
