PROBLEM TO BE SOLVED: To provide a hole-in anchor and a connection structure that facilitate processing of an existing structure for installation and shorten an embedded length of a shaft part into the existing structure.SOLUTION: A hole-in anchor 3 is a hole-in anchor for connecting an existing structure 1 with a new structure 2, and includes a cylindrical shaft part 31 and a protruded part 32. The protruded part 32 is disposed on the shaft part 31, where the greatest length l1 of the shaft part 31 in a radial direction is three time or more of an outer diameter d1 of the shaft part 31. The protruded part 32 is embedded in the new structure 2 when the existing structure 1 is connected with the new structure 2, and a boundary side surface 32a of the protrusion 32 that faces a boundary surface 10 between the existing structure 1 and the new structure 2 comes in contact with the new structure 2.SELECTED DRAWING: Figure 6
【課題】施工に必要な既存構造体への加工を容易にすることができ、かつ軸部の既存構造体への埋め込み長さを短くすることができるあと施工アンカーおよび接合構造を提供すること。【解決手段】あと施工アンカー３は、既存構造体１と新構造体２とを接合するためのあと施工アンカーであって、円柱状の軸部３１と、突出部３２と、を備える。突出部３２は、軸部３１に設けられ、軸部３１の径方向における最大長さｌ１が軸部３１の外径ｄ１の３倍以上である。既存構造体１と新構造体２とが接合された状態において、突出部３２は、新構造体２に埋まっており、突出部３２のうち既存構造体１と新構造体２との境界面１０に対向する境界側表面３２ａは、新構造体２に接する。【選択図】図６
