CONNECTOR AND CONNECTING APPARATUS FOR CONCRETE MEMBER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a connector that minimizes an aperture between shield segments as much as possible, and a connecting apparatus for a concrete member using the same.SOLUTION: A casing 3 contains a housing chamber 4 with an opening formed at a tip. A wedged female locking member 12 divided circumferentially is arranged in the housing chamber 4 so as to slide in an axial direction. A connector includes a female connecting member 1 formed by biasing a female locking member 12 forward by a biasing means 15, and a male connecting member 2 with a male locking member 23 formed at the tip. The male locking member 23 is inserted into a locking hole to increase the diameter, then the biasing means 15 reduces the diameter of the locking hole. A locking part of the female locking member 23 is engaged with a locking member of the male locking member 12. A base part 25a is disposed at a deeper side than the locking part of the male locking member 23. In at least a part of the base part, the outer diameter gradually increases toward the deep side.
