ANCHOR CONSTRUCTION METHOD, ANCHOR SYSTEM, ANCHOR CONSTRUCTION TOOL, AND ANCHOR
To provide an anchor construction method, an anchor system, an anchor construction tool, and an anchor for enabling a constructor or a manager to visually confirm completion of anchor construction to improve visibility of the anchor.SOLUTION: An anchor construction method includes: a step of inserting an internal cone driving type anchor into a hole formed on a concrete part, the anchor including a plurality of extension parts that are provided on the tip side and are deformable externally in the radial direction and including a colored part formed on at least part of an end surface of a base end part; a step of inserting into the inside of the anchor an insertion part of an anchor construction tool, which includes the insertion part to be inserted into the inside of the anchor and a connection part having an outer diameter larger than that of the insertion part; a step of applying an impact in a center axis direction to the anchor construction tool while rotating the tool around a center axis to expand the extension parts externally in the radial direction in the hole; and a step of visually confirming completion of anchor construction in the hole on the basis of the presence/absence of abrasion of the colored part of the end surface caused by contact with the connection part.SELECTED DRAWING: Figure 6
【課題】施工者又は管理者がアンカーの施工完了を目視で確認でき、アンカーの視認性を高める、アンカーの施工方法、アンカーシステム、アンカー施工用工具、アンカーを提供する。【解決手段】先端部側に径方向外側に変形可能な複数の拡張部を有するとともに、基端部の端面の少なくとも一部に着色部が形成された内部コーン打込み式のアンカーを、コンクリート部に形成された孔に挿入する工程と、アンカーの内側に挿入される挿入部、及び挿入部よりも外径が大きな接続部を有するアンカー施工用工具の挿入部を、アンカーの内側に挿入する工程と、アンカー施工用工具を中心軸回りに回転させつつ中心軸方向に打撃を加えて、孔内でアンカーの拡張部を径方向外側に拡張させる工程と、接続部との接触による端面の着色部の削れの有無に基づいて、孔内におけるアンカーの施工完了を目視で確認する工程と、を含むアンカーの施工方法である。【選択図】図６
