ABSTRACT:
An anchor for resisting a pulling force applied to a cable includes an expandable outer shell disposed in an opening in a floor, an outer wedge disposed in the shell and having wedge-shaped projections engaged with the inner wall of the shell, and a rotatable inner wedge below the outer wedge engaged with a short length of chain extending through the shell. A cable to be tensioned is attached to the short length of chain. Tension on the cable urges the inner wedge upwardly against the outer wedge which, in turn, is wedged in the interior of the shell to forceably expand the walls of the shell radially outwardly to embed the shell in the floor. The inner wedge is rotatable axially relative to the outer wedge between a first position, in which a wedging force is applied to the outer wedge in response to tensioning of the cable, and a second position, which allows removal of the inner wedge and the short length of chain from the outer wedge and the shell.
