Abstract
A structure of base of column and a construction method for base of column formed by installing a lower end of column steel frame on a foundation formed under the ground. 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. By these measures, a number of parts for combining the base of column and a construction cost can be reduced, a support strength of the column steel frame can be improved, and a number of construction work processes of the base of column can be reduced.
