ANCHOR REINFORCEMENT STRUCTURE, ANCHOR REINFORCEMENT METHOD, AND ANCHOR REINFORCEMENT MEMBER

To provide an anchor reinforcement structure capable of efficiently reinforcing an anchor bolt, an anchor reinforcement method, and an anchor reinforcement member.SOLUTION: A reinforcement member 11 is constituted of a shaft member 13 and a fixing member 15. The shaft member 13 has an expanded portion formed at one end and a male screw part formed on the other end portion thereof. There exists a shank portion between the expanded portion and the male screw part. A diameter of the shank portion is smaller than a diameter of a trough of the male screw part. The fixing member 15 is capable of receiving the shaft member 13 therein. The fixing member 15 has a hole 25 formed at one end thereof, through which the male screw part and the shank can be inserted. The expanded portion is joined to a thread portion 9a of an anchor bolt 9. In this state, the fixing member 15 is disposed to cover the shaft member 13 with the male screw part protruding upward from the hole 25 of the fixing member 15. A nut 17 is provided to the male screw part and is fixed to an upper portion of the fixing member 15.SELECTED DRAWING: Figure 2 【課題】 効率よくアンカーボルトの補強が可能なアンカー補強構造、アンカー補強方法およびアンカー補強部材を提供する。【解決手段】 補強部材１１は、軸部材１３と固定部材１５とからなる。軸部材１３は、一方の端部に拡径部が設けられ、他方の端部に雄ねじ部が設けられる。拡径部と雄ねじ部との間が軸部となる。なお、軸部の径は、雄ねじ部の谷部の径よりも小さい。固定部材１５は、内部に軸部材１３を収容可能である。固定部材１５の一方の端部には、雄ねじ部および軸部を挿通可能な孔２５が形成される。拡径部は、アンカーボルト９のねじ部９ａと接合される。この状態で、軸部材１３を覆うように固定部材１５が配置され、固定部材１５の孔２５から、雄ねじ部が上方に突出する。さらに、雄ねじ部にはナット１７が設けられ、固定部材１５の上部に固定される。【選択図】図２
