ANCHOR, ANCHOR EXTRACTING TOOL, ANCHOR UNIT, AND ANCHOR REMOVING METHOD
To provide an anchor, an anchor extraction tool, an anchor unit, and an anchor removing method, capable of easily performing an extraction work from a skeleton.SOLUTION: An anchor includes a tubular sleeve which extends along a central axis and has an extension on one side in an axial direction, an anchor bolt which is inserted into the sleeve and has a taper which expands an extension portion, a nut which is attached to the anchor bolt, and a washer provided between the nut and the sleeve and having a first portion and a second portion. The sleeve has a groove formed on an outer peripheral surface. The first portion and the second portion are portions orthogonal to the axial direction, and the first portion is located on one side in the axial direction and the outer side in a radial direction with respect to the second portion. And at least a part of the groove is located between the first portion and the second portion which contacts with the sleeve in the axial direction.SELECTED DRAWING: Figure 2
【課題】躯体から引き抜き作業を簡便に行うことができる、アンカー、アンカー抜取用工具、アンカーユニット、アンカーの撤去方法を提供する。【解決手段】中心軸に沿って延び、軸方向の一方側に拡張部を有する筒状のスリーブと、スリーブに挿入され、拡張部を拡張させるテーパー部を有するアンカーボルトと、アンカーボルトに取り付けられるナットと、ナットとスリーブとの間に設けられ、第１部分及び第２部分を有する座金と、を備え、スリーブは、外周面に形成された溝部を有し、第１部分及び第２部分は軸方向に直交する部位であって、第１部分は第２部分よりも軸方向の一方側及び径方向外側に位置しており、溝部の少なくとも一部は、軸方向において、第１部分と、スリーブに接触する第２部分と、の間に位置するアンカーである。【選択図】図２
