Abstract:
A cable anchor adapted to be located at the bottom of a foundation piling having a plurality of piling segments, each having an aligned hole for receiving a cable, comprising:a plurality of lock members, each having an outer wall and a partially cylindrical recess formed on an inner wall, the lock members being arranged around a longitudinal axis of the cable anchor so that the recesses combine to define an axially extending lock member passage for receiving an end of the cable; a cam surface that mates with the lock members so that axial movement of the lock members and the cam surface in a first direction causes the lock member passage to expand to receive an end of the cable, and axial movement of the lock members and the cam surface in a second direction causes the lock member passage to constrict to grip the end of the cable to post-tension the piling; and a resilient member that urges the lock members and the cam surface toward the second direction.
