PROBLEM TO BE SOLVED: To simplify reinforcing work, when reinforcing a yield strength insufficient anchor bolt particularly put in a use state, by imparting the shock absorbing function to the anchor bolt for anchoring an upper structure in a lower structure.;SOLUTION: This anchor bolt 2 anchors a baseplate 7 integrated into the lower structure 8 side of a bearing body 6 supporting the upper structure 5 in the lower structure 8. An anchor bolt 1 with a shock absorbing material is composed of the anchor bolt 2 and a cylindrical shock absorbing material 4 arranged around a head part 2a of its anchor bolt 2, and is arranged around the anchor bolt 2 in a state of exposing the shock absorbing material 4 to the upper surface side of the baseplate 7, and is sandwiched between an upper surface of the baseplate 7 and a nut 3 threadedly engaging with the head part 2a of the anchor bolt 2.;COPYRIGHT: (C)2007,JPO&INPIT
