Occasionally, construction errors lead to protruding rebar from the reinforcement being unthreaded or lacking sufficient length for lapping. In such instances, pressing couplers offer a reliable solution for creating connections between the reinforcing bars. This type of coupler establishes a mechanical connection with the necessary strength without requiring threading. To utilize this coupler type, a minimum 30-centimeter protrusion of the rebar from the concrete and adequate surrounding space to accommodate the pressing coupler tool are necessary.
This mechanical connection has undergone testing in the Pertless company laboratory using a rebar tensile testing machine. The test results demonstrate a strength exceeding 1.6 times the rebar’s yield strength. According to the American ACI code, this level of strength indicates the suitability of this connection type for use in all structural members of a building.
