  • Patent number: 9506250
    Abstract: An assembly for connecting a first rebar segment and a second rebar segment. The assembly includes a first wedge and second wedge, each defining a hollow for receiving the first and second rebar segments, respectively. A first barrel and a second barrel each define a passage for receiving the first and second wedges, respectively. The passages are tapered for mating engagement with the wedges for driving the wedges radially inwardly in response to the wedges being in the passages and axially engaged by the barrels to tighten the wedges about the rebar segments. A cap defines an opening, a stopping surface, and a channel that extends axially between the opening and the stopping surface, receiving the first and second barrels in axial alignment with one another. A coupling connects the cap and one of the barrels, inhibiting axial movement of the barrels out of the channel of the cap.

  • Patent number: 9062457
    Abstract: A method and assembly for anchoring a segment of rebar and a plate to a mass. The assembly includes a barrel extending about and along an axis and defining a bore extending therethrough along the axis with the bore being tapered. A wedge having a frustoconical shape extends about and along the axis. The wedge is tapered in conformity with the bore of the barrel for being received by the barrel. A cap is connected to the barrel for closing the barrel. The method includes the step threadedly tightening the cap about the barrel in axial abutment to close the barrel, and further the step of compressing the wedge axially into the bore of the barrel to drive the wedge radially inwardly to provide for a biasing force of the wedge against the rebar prior to said step of threadedly tightening the cap about the barrel.
