CONCRETE BURIED BODY AND SETTING TOOL

摘要

A thin disk-shaped boss body (51) having a projection (52) and the like is mounted to a formwork (60). An insert holder (40) comprises an outer cylindrical portion (35) and an inner cylindrical portion (31) on a setting side (30) with a gap (34) therebetween. An inner surface of the inner cylindrical portion (31) constitutes a mounting portion (39) and is provided along an inner periphery thereof with a groove (33). When the insert holder (40) is set on the boss body (51), the projection (52) is engaged with the groove (33) whereby an insert (1) can be mounted to the formwork with an adequate attaching force. When stripping is to be effected, the formwork (60) is caused to turn, and then the inner cylindrical portion (31) is pushed into the gap (34) by the boss body (51), so that the boss body (51) does not interfere with surface of a concrete product to enable performing a stripping operation without disengagement of the boss body (51).
