To provide an anchor bolt capable of performing construction according to required pull-out strength.SOLUTION: A collar-shaped contact stopper is provided on a tip of a bolt. An expansion ring is split into a plurality of parts in a rear-side half part of a cylinder body with axial-directional slits to form an expansion part. Further, a male taper according with a female taper described later is provided on a tip of the cylinder body, and the female taper which receives the male taper is formed on a rear end. The tapered ring is provided with the male taper according with the female taper provided on a rear end of the expansion ring and, at the same time, is provided with a plurality of projections as detent on the circumference. The expansion rings of the number necessary in terms of strength for the bolt are inserted and, further, the tapered rings and fastening nuts are arrayed in this order from the front side toward the rear side.SELECTED DRAWING: Figure 1
【課題】要求される引き抜き強度に応じた施工が可能なアンカーボルトを得る。【解決手段】ボルトの先端に鍔状の当たり止めを設けておく。拡張リングは、筒体の後方半分に軸方向のスリットで複数に分割されて拡張部を形成する。また、前記筒体の先端に、後述の雌テーパに符合する雄デーパを備え、後端に前記雄テーパを受ける雌テーパが形成される。前記テーパリングは、先端に前記拡張リングの後端に設けた雌テーパに符合する雄テーパを備えとともに、回り止めとなる複数の突起を周囲に備えている。前記ボルトに対して強度的に必要な個数の前記拡張リングを挿通し、更に、テーパリング、締め付けナットが上記の順に先方から後方に向かって配列される。【選択図】図１
