摘要

PROBLEM TO BE SOLVED: To provide a joint structure for concrete members having excellent workability and economical efficiency. SOLUTION: This is a joint structure using male and female fittings which are jointed together by butting together the end faces of members having predetermined wall thicknesses, and the male fittings 9 has a head portion 11 having an expanded portion 13 and an under head constriction 14 which projects out from a joint end face of one of the member, and a linking claw 22 exerted by a spring is provided inside a linking cylindrical hole 19 in a freely movable manner back and forth in a perpendicular direction to the inserting direction of the male fittings 9 at the cylindrical wall 20 of the female fittings 8, and after the ingress of the male fittings 9 by pushing and retreating the linking claw 22, the linking claw 22 can be linked to an expanded portion 13 of the male fittings 9 in configuration.
