Plural column main reinforcing-bars, which have bottom bent portions and are incorporated in a foundation concrete at specified positions corresponding to a sectional shape of column, are protruded upward out of a top face of the foundation concrete and a lower end base plate of the column steel frame is combined to upper protruding portions of the column main reinforcing-bars. As combining measures, there are such measures that a tightening nuts are screwed onto male threaded portions provided on the protruding portions of the column main reinforcing-bars, or caulked portions are formed on the protruding portions of the column main reinforcing-bars.
