Summary: | To provide a construction method of an anchor for concrete which is excellent in construction efficiency, minimizes a load applied to a concrete skeleton, and surely maintains strength and durability required for the concrete skeleton.SOLUTION: A construction method of an anchor for concrete comprises: a first step of extracting an existing original anchor 50 from an existing hole 101 of a concrete skeleton 100; a second step of drilling a new hole 102 concentrically with the existing hole 101 with a drilling diameter larger than a diameter of the existing hole 101, preferably with a drilling depth deeper than a depth of the existing hole 101; and a third step of placing a new renewal anchor 10 in the new hole 102.SELECTED DRAWING: Figure 3
【課題】施工効率に優れると共に、コンクリート躯体にかかる負荷を最小限に留め、コンクリート躯体に必要とされる強度や耐久性を確実に維持することができるコンクリート用アンカーの施工方法を提供する。【解決手段】コンクリート躯体100の既設穴101から既存の元アンカー50を抜き取る第1工程と、既設穴101と同心状に、既設穴101より径が大きい削孔径で、好適には既設穴101より深さが深い削孔深さで、新設穴102を削孔する第2工程と、新設穴102に新たな更新アンカー10を打設する第3工程を備えるコンクリート用アンカーの施工方法。【選択図】図3 |
