ANTI-CORROSIVE CONNECTION MEMBER AND CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a connection member having high strength and high resistance to corrosion and to provide a concrete structure having high durability for a long time. SOLUTION: A ceramic insert 10 being a nut member is buried into an end part in the axial direction of a segment 5 to be connected on one side through a ceramic sleeve 11. A bolt hole 5a is provided by passing through in the axial direction of a segment 5 on the other side. A metallic bolt member 13 whose surface is covered with an anti-corrosive covering layer is inserted into the bolt hole 5a. The metallic bolt member 13 is inserted into the ceramic sleeve 11 to screw-fit into a female screw part 10a of the ceramic insert 10. COPYRIGHT: (C)2004,JPO
