PROBLEM TO BE SOLVED: To provide a method for manufacturing an additive member to an existing concrete structure, which does not undergo displacement of through hole in the additive member, and is excellent in workability. SOLUTION: According to the method, a plurality of anchor bars 2 are embedded in the existing concrete structure 103, and distances between one or more reference points S0 set in the concrete structure and axial centers of the respective anchor bars 2 are measured, followed by determining locations of third points, based on the measured distances between the two known points, respectively. Then, the above procedures are repeatedly carried out, and geometrical data expressing all the axial points in the form of the mutual distances are prepared. Thereafter, the geometrical data are converted into NC data, and then the through hole 131 into which the anchor bar 2 is inserted is formed in the additive member 104, based on the NC data. |
