Zusammenfassung:PROBLEM TO BE SOLVED: To provide a construction method of a column base which simplifies the construction and can avoid the problem of durability, a reinforcement method of an existing column base and the like.SOLUTION: When reinforcing the existing column base, an intermediate detachable nut 35 is attached to an anchor bolt 31 embedded in a foundation 2 in the vicinity of the existing column base. Then, a base plate 25 to which a reinforcing column 23 is joined is disposed on the intermediate detachable nut 35. Thereafter, the base plate 25 is fixed to the anchor bolt 31 by a nut 33, and the reinforcing column 23 is joined to an existing column 3. As a result, the position of the reinforcing column 23 is fixed, so that the intermediate detachable nut 35 is removed and a space between the foundation 2 and the base plate 25 is filled with the mortar.SELECTED DRAWING: Figure 7 【課題】施工が容易であり、且つ耐久性の問題を回避できる柱脚の施工方法、および既存柱脚の補強方法等を提供する。【解決手段】既存柱脚を補強する際に、既存柱脚の近傍において、基礎2に埋設されるアンカーボルト31に中間着脱式ナット35を取り付ける。そして、中間着脱式ナット35上に、補強柱23が接合されたベースプレート25を配置する。その後、ナット33によってベースプレート25をアンカーボルト31に固定し、補強柱23を既存柱3に接合する。これにより補強柱23の位置固定が行われるので、中間着脱式ナット35を取り外して、基礎2とベースプレート25の間にモルタルを充填する。【選択図】図7
