PROBLEM TO BE SOLVED: To secure a sufficient anchoring force without being restricted by the concrete strength of an existing structure and the buried depth of an anchor reinforcement in an after-constructed anchor.SOLUTION: A filler (14) is filled by burying the anchor reinforcement (12) having an anchor plate (12a) at the tip, into a hole (10) bored with a taper so that the diameter is gradually increased in a depth direction from the surface of the existing structure (1), and separation is performed from the surface of the existing structure at least to a predetermined depth so that a sticking force is not applied between the side face of the anchor reinforcement and the filler. |
