ているのが実情であった。[Technical Background of the Invention] As a method of loading a steel column with a tower crane and vertically abutting the steel column or the steel column already constructed, a chain block is connected after a beam is assembled. In this case, the chain block was pulled to somewhere to obtain the verticality. The leveling of the steel columns was adjusted separately with jacks after assembling the beams. As described above, the method of pulling out the verticality of the steel column by assembling the steel column and the beam after assembling the column and the vertical direction of the steel column has been returned to the original state when the chain block is released after the verticality is adjusted.

年７月２１〜２２日参照）2. Description of the Related Art As means for solving such a technical problem, as shown in FIG. 5, an adjusting member having a prism and a pyramid is provided at the upper end of a foundation pillar or a steel pillar already constructed. After the steel column to be built above the steel column is carried in by a tower crane and butted, the adjusting bolt screwed to each lower surface of the upper steel column is advanced and retracted. Means has been proposed for obtaining the verticality of a steel column while causing the tip of the adjusting bolt to contact the pyramidal surface and the prism surface.
