ある。Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to these embodiments, and that the seed design can be modified without departing from the spirit of the present invention. Therefore, the present invention is also applied to cast-in-place reinforced concrete columns, in which case the column reinforcing bars pre-assembled in a factory are fixed to a steel foundation, transported to the site and erected, and then placed around the column. This is a structure in which formwork is arranged and concrete is poured, and the work of fixing the main column reinforcement to the foundation part, which is required in the conventional reinforcing steel on-site assembly method and pre-assembly method, is omitted, and the structure is constructed in advance. It can be built on the foundation of a steel frame using the same method as a steel frame column, and construction can be significantly simplified.
