<P>PROBLEM TO BE SOLVED: To provide a snake insert anchor bolt which can be mounted so as not to come into contact with a reinforcing-bar being present at a mounting position of a concrete structure with the reinforcing-bar embedded therein. <P>SOLUTION: In a snake insert anchor bolt 10, an anchor body 12 can be inserted into a mount hole 38 provided in a mold form 36 prior to concrete casing of a concrete structure 30 with a reinforcing-bar 32 embedded therein. The anchor body 12 includes an internal thread 20 mounted on the same plane as a mounting surface of the concrete structure 30, a first bent portion 22 which is formed by bending an end portion of the internal thread 20, a first shaft 24 extending from the first bent portion 22, a second bent portion 26 which is formed by bending a terminal portion of the first shaft 24, and a second shaft 28 extending from the second bent portion 26. The internal thread 20 is characterized by that an axial center is formed linear and that the anchor body 12 can be inserted while being revolved from the outside of the mount hole 38 to the side of the reinforcing-bar 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
