PROBLEM TO BE SOLVED: To provide a building method of steel column for building a steel column vertically on a pile head cast-in-place pile.SOLUTION: In a borehole 2 which is formed for construction of the cast-in-place pile 3 in which a leg portion 4a of the steel column 4 is disposed, plural mechanical jacks 10, which expands/contracts by means of gear engagement, are disposed horizontally in an expansion/contraction direction being oriented to the axis of a steel column 4 at equal angular distance from each other around the steel column 4 at the same depth. The steel column 4 is supported and the perpendicularity thereof is adjusted by means of expansion/contraction of the mechanical jacks 10.SELECTED DRAWING: Figure 2
【課題】場所打ち杭の杭頭に立設される鉄骨柱を垂直に自立させるための鉄骨柱の建込方法を提供する。【解決手段】場所打ち杭３を施工するために形成され鉄骨柱４の脚部４ａが配置される掘削孔２内に、歯車の噛み合いにより伸縮する複数台の機械式ジャッキ１０を、それぞれの伸縮方向が水平であり、かつ、鉄骨柱４の軸中心を向くように、鉄骨柱４の柱軸まわりに等しい角度間隔で、同じ深さに配置し、これらの機械式ジャッキ１０の伸縮により鉄骨柱４の支持および垂直度の調整を行う。【選択図】図２
