FASTENING ANCHOR AND CONSTRUCTION METHOD THEREFOR
To properly expand and surely fix an expansion member to a concrete skeleton even if a locking nut is applied, and to perform nut locking.SOLUTION: The present invention relates to a fastening anchor 1 in which an expansion member 3 in which an expansion blade 31 which is expanded in response to pull-in of a tapered part 24 is formed while being partitioned by a groove part is fitted onto a diameter reduction part 22 of a tapered bolt 2 in which the diameter reduction part 22 and the tapered part 24 are provided at a front side and a male screw part 25 is provided at a rear side of a shank 21, and a locking nut 4 in which a friction piece 42 which is elastically deformed by engagement with the male screw part 25 is provided is threaded to the male screw part 25. An engage projection 242 which enters the groove part and is engaged in response of the pull-in of the tapered part 24 to the expansion member 3 is provided on a tapered surface 241, and a diameter of a circumscribed circle circumscribed on an outermost end of the expansion member 3 in a non-expanded state in a radial direction is set to be equal to or larger than a maximum outer diameter of the tapered part 24 and substantially equal with an excavated hole diameter of a concrete skeleton 10.SELECTED DRAWING: Figure 6
【課題】緩み止めナットを適用しても適正に拡開部材を拡開してコンクリート躯体に確実に定着することができると共に、ナットの緩み止めを行うことができる。【解決手段】軸部２１の前側に縮径部２２とテーパ部２４が設けられ、後側に雄ねじ部２５が設けられているテーパボルト２の縮径部２２に、テーパ部２４の引き込みに応じて拡開する拡開羽根３１が溝部で区分して形成された拡開部材３が外嵌され、雄ねじ部２５への係合で弾性変形するフリクション片４２が設けられた緩み止めナット４が雄ねじ部２５に螺合された締付式アンカー１であり、テーパ面２４１に拡開部材３へのテーパ部２４の引き込みに応じて溝部に入り込んで係合する係合突起２４２が設けられ、非拡開状態の拡開部材３の半径方向の最外端に外接する外接円の径が、テーパ部２４の最大外径以上で且つコンクリート躯体１０の削孔径と略同一に設定される。【選択図】図６
