<P>PROBLEM TO BE SOLVED: To prevent concrete from being cracked without propagating the deformation of male type hardware used as a segment joint structure to the concrete of an embedded part when the male type hardware is deformed to be bent by an external force when assembling segments in a ring shape. Ž<P>SOLUTION: The male type hardware 19 embedded in a segment joint face 15 includes: a male type hardware body 19a having a locking part 19b at the tip side; a plate-like high rigidity member 20 used as an embedding member; and an anchor reinforcement 18. The high rigidity member 20 and the anchor reinforcement 18 of the male type hardware 19 are embedded in the concrete 21 of the segment joint face 15, and the front face of the high rigidity member 20 is exposed to the segment joint face 15. When the male type hardware body 19a is deformed by the external force, the deformation is received by the high rigidity member 20. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
