Abstract:
1. A method for anchoring a segment of rebar to a mass using a barrel extending along and about an axis and defining a bore being tapered extending therethrough along the axis and a wedge being tapered and defining a hollow extending therethrough along the axis and a cap, said method comprising the steps of: extending the rebar axially into the mass, extending the bore of the barrel about the rebar, extending the hollow of the wedge about the rebar axially adjacent to the mass, connecting the cap to the barrel to close the barrel to inhibit movement of the wedge out of the barrel, 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 connecting the cap to the barrel to close the barrel, and extending a spring washer about the segment of rebar axially against the wedge to compensate for movement of the rebar relative to the barrel and to provide for more uniform compression of the cap onto the wedge.
