Abstract

PURPOSE:To erect a steel column without using a crane truck and the like, in the case of building a steel frame construction, at a construction site and the like where width of a road thereto is so narrow that the crane truck and the like can not travel to the site. CONSTITUTION:A base stand 5 is provided with a ball passage 6 inclining upward, a feed-in device 12 for a ball 13 detachably and a guide 4 facing upward. A column single unit 10 is assembled and constituted of a column member 9 and a plate body in correspondence with the guide 4. A top wall 11 is fitted thereto, balls 13 are press-fed by the press-in device 12 so as to thereby push up and raise the top wall 11 of the column single unit 10. Another column single 10 is assembled and added under this, connected to the column single unit 10 thereabove, raised and another column single unit 10 is added. This process is repeated until a target height is attained. Then, the press-in device 12 is removed, balls 13 are taken out and the lower end of the column single unit is welded to the base stand 5.
