PROBLEM TO BE SOLVED: To enable an anchor-bolt to be accurately positioned at a center position of an embedment hole and to prevent an adhesive from dripping-off from an upward embedment hole, the anchor-bolt being such a type as to be inserted into the embedment hole in a structure and fixed to the structure by hardening the adhesive filled in a clearance between the embedment hole and the anchor-bolt.SOLUTION: A positioning tool 10 which can be mounted on an anchor-bolt comprises a cylindrical body 11 and a plurality of protrusions 12 connected to outer peripheral surface of the body 11 and having nearly the same protrusion amount in the radial direction. When the anchor-bolt 20 mounted with the positioning tool 10 is inserted into an embedment hole 41 of a structure 40, apexes of the respective protrusions 12 abut on the inner surface of the embedment hole 41, and thus the anchor-bolt 20 is accurately positioned at a center position of an embedment hole 41. When the embedment hole 41 is upward directed, the respective protrusions 12 are hooked to the inner surface of the embedment hole 41 or stuck in an adhesive filled in the hole, which generates resistance against falling. Thereby, the anchor-bolt 20 is prevented from dropping down. |
