DEXTRA REBAR COUPLER SYSTEMS
Construction Week|January 2022
Reinforced concrete design and construction practice has historically focuses on the use of lap splicing as a method of transferring load between reinforcement bars.
DEXTRA REBAR COUPLER SYSTEMS

This relies on the load being transferred from one rebar, through the surrounding concrete and into the adjacent lapped rebar. However, the lapping of reinforcement is not always the most appropriate splicing method and there are many situations where the use of mechanical rebar couplers is more desirable from a design perspective, more convenient from a construction perspective, or both.

Rebar coupler systems, sometimes also known as mechanical splices, are used as an alternative to traditional lap splices in concrete. They transmit the rebar load directly from one rebar to another without relying on concrete bond, concrete strength, or the condition of the concrete surrounding the rebar and coupler.

Advantages

There are many well-documented advantages to using rebar coupler systems. These include:

2.1 Rebar Continuity

Reinforced concrete design codes of practice, including IS 456 , assume that the detailing, quality of materials and workmanship is such that the transmission of forces in a lap splice from one rebar to the other is assured. However, if the bond between the concrete and the rebar is lost, possibly because of concrete cracking, deterioration, poor on site workmanship, rebar corrosion and subsequent spalling etc. then the rebar lap splice may fail. Rebar couplers do not rely on concrete bond and therefore they create more reliable rebar continuity.

2.2 Avoidance of Transverse Splitting Forces
