PRESSURE CONNECTION GRIP IN CABLE FOR BRIDGE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pressure connection grip having a structure heightening its strength at a grip body as a whole by biting into a PC-steel stranded wire. SOLUTION: A protruded streak 2 crossing a shaft center of a grip body is formed on an inner peripheral face of a hole in the grip body 1. A surface layer of an inner hole periphery including the protruded streak 2 is formed at least harder than a PC-steel stranded wire and others are softer than the PC-steel stranded wire.
