GROUTED COUPLER FOR SPLICING STEEL REINFORCEMENT BARS
Disclosed is a grouted coupler for splicing together a pair of steel reinforcement bars (i.e., rebars) that are embedded within first and second concrete members to be connected together. In one embodiment, the first rebar is connected to a first coupling cavity of the coupler within the first concrete member. A wide upset head of the second rebar that stands upwardly from the second concrete member moves through a second coupling cavity of the coupler and into a grout receiving chamber when the first concrete member is moved towards the second concrete member. The second rebar is connected to the coupler when grout is pumped into the grout receiving chamber to surround and anchor the upset head of the second rebar. A spring-biased grout removal stop is positioned within the second coupling cavity to impede the free flow of grout outwardly from the grout filled chamber.
