To provide a screw-in type anchor that enables safe construction and also provides efficient inspection work after the construction by making it easy to confirm a construction state.SOLUTION: A screw-in type anchor 1 is screwed in a hole formed in a skeleton to be fixed to the skeleton, and comprises: an anchor bolt 10 which has a shaft part 11 screwed in the hole and a large-diameter part 12 provided on a base end part side of the shaft part 11 and having a larger diameter than an outer diameter of the shaft part 11; an indicator holding member 5 which has an expanded part 51 inserted in the shaft part 11 and expanded with axial pressing force from the large-diameter part 12, and is provided with holding parts 54 at front ends of the expanded part 51; and an indicator 6 which is held by the holding parts 54 and arranged to surround the large-diameter part 12, wherein as the shaft part 11 is screwed in the hole, the large-diameter part 12 moves toward a tip of the shaft part 11 to press the indicator holding member 5, and the expanded part 51 is expanded to separate the indicator 6 from the holding parts 54.SELECTED DRAWING: Figure 2
【課題】安全な施工を行えるようにするとともに、施工状態を簡単に確認できるようにして施工後の点検作業を効率良く行えるようにしたねじ込み式アンカーを提供する。【解決手段】躯体に形成された孔にねじ込むことで躯体に固定されるねじ込み式アンカー１あって、孔にねじ込まれる軸部１１と、軸部１１の基端部側に設けられ、軸部１１の外径よりも大径である大径部１２とを有するアンカーボルト１０と、軸部１１に挿通され、大径部１２からの軸方向の押圧力によって拡開する拡開部５１を有し、拡開部５１の先端に保持部５４が設けられたインジケータ保持部材５と、保持部５４によって保持され、大径部１２を包囲するように配置されるインジケータ６とを備え、軸部１１が記孔に対してねじ込まれることによって大径部１２が軸部１１の先端方向に移動してインジケータ保持部材５を押圧し、拡開部５１を拡開させて保持部５４からインジケータ６を離脱させる。【選択図】図２
