Claims

[Scope of claims for utility model registration] (1) An insert body buried in a structure;
The insert device includes a bolt whose one end is inserted into and coupled to the insert body, the insert body having an insertion hole for the bolt and a restraining chamber and an expansion chamber coaxially communicating with the insertion hole. The restraint chamber is formed into a cylindrical shape with a
A pair of wedge members facing each other in the radial direction of the restraining chamber are slidably installed inside the restraining chamber, and grooves into which the wedge members engage are provided at two opposing positions on the outer periphery of one end of the bolt. and,
One end surface of the bolt is formed into a tapered surface that enters between both wedge members and separates both wedge members when the bolt is inserted, and the inner wall of the restraining chamber has a tapered surface that allows the wedge member to move when the wedge member engages with the groove. The inner wall of the enlarged chamber has a shape that allows the wedge members to slide only in the radial and axial directions of the enlarged chamber, and that allows the wedge members to move closer to each other. An insert device characterized in that it has a guide slope that guides toward the restraint chamber. (2) The insert device according to claim 1, wherein a resilient member is loaded in the enlarged chamber to urge the wedge member toward the bolt insertion hole.
