Summary:To provide a temporary scaffold which can be constructed in a pile erected in a water area having an anticorrosive layer at a desired height position while avoiding damage of the anticorrosive layer, and a method for constructing a temporary scaffold.SOLUTION: A temporary scaffold 1 has a fixing member 3 composed of a plurality of division bodies 3a, a plurality of upper pressing members 4 provided on the inner peripheral side of the fixing member 3, a plurality of support members 8 whose one end is joined to the fixing member 3, support legs 9 whose upper end is connected to each of the support members 8, lower pressing members 10 provided on the lower end of each of the support legs 9 and scaffold boards 13 supported by the plurality of support members 8, in which the fixing members 3 are annularly wound around the outer periphery of a pile 20, inner peripheral surfaces of each of the upper pressing members 4 and each of the lower pressing members 10 are pressed against the outer peripheral surface of the pipe 20 and a soft non-metal buffer material 5 is pressed against an anticorrosive layer 21, and thereby the temporary scaffold 1 is fixed to the pile 20.SELECTED DRAWING: Figure 2 【課題】防食層を有する水域に立設された杭に対して、防食層の損傷を回避して所望の高さ位置に仮設足場を構築できる仮設足場および仮設足場の構築方法を提供する。【解決手段】複数の分割体３ａで構成された固定部材３と、固定部材３の内周側に設けられた複数の上側押圧部材４と、固定部材３に一端部が接合された複数の支持部材８と、それぞれの支持部材８に上端部が連結された支持脚９と、それぞれの支持脚９の下端部に設けられた下側押圧部材１０と、複数の支持部材８に支持される足場板１３とを有する仮設足場１を使用し、杭２０の外周に固定部材３を環状に巻装し、それぞれの上側押圧部材４およびそれぞれの下側押圧部材１０の内周面を杭２０の外周面に押し当て、防食層２１には非金属製の軟質の緩衝材５を押し当てた状態にすることで、杭２０に対して仮設足場１を固定する。【選択図】図２
