PROBLEM TO BE SOLVED: To provide an anchor capable of obtaining a high pull-out strength.SOLUTION: An anchor 100 according to the present invention includes a sleeve 10, a first cone 20, and a second cone 30. The sleeve 10 has an expansion part 16 which is expanded by the first cone 20 and the cone 30. The expansion part 16 is provided on the side of a first opening 11a. The expansion part 16 has a first part 16a whose inner diameter becomes smaller from the side of the first opening 11a toward the side of the second opening 11b, and a second part 16b whose inner diameter becomes smaller from the side of the second opening 11b toward the side of the first opening 11a. The second part 16b is expanded when the second cone 30 is inserted into the second part 16b by driving the second cone 30 into the second part 16b, and the first part 16a is expanded when the first cone 20 is inserted into the first part 16a by driving the sleeve 10 into a base material 2.SELECTED DRAWING: Figure 8
【課題】高い引き抜き強度が得られるアンカーを提供する。【解決手段】本発明に係るアンカー１００は、スリーブ１０と、第１コーン２０と、第２コーン３０と、を含み、スリーブ１０は、第１コーン２０および第２コーン３０によって拡張される拡張部１６を有し、拡張部１６は、第１開口１１ａ側に設けられ、拡張部１６は、第１開口１１ａ側から第２開口１１ｂ側に向かうに従って内径が小さくなる第１部分１６ａと、第２開口１１ｂ側から第１開口１１ａ側に向かうに従って内径が小さくなる第２部分１６ｂと、を有し、第２部分１６ｂは、第２コーン３０が第２部分１６ｂに打ち込まれることで第２コーン３０が第２部分１６ｂに挿入されて拡張し、第１部分１６ａは、スリーブ１０が母材２に打ち込まれることで第１コーン２０が第１部分１６ａに挿入されて拡張する。【選択図】図８
