By injecting a filler between the column and the sheath steel pipe, the column and the beam are easily joined, and the protrusion arranged on the inner surface of the steel pipe, the sheath steel pipe and the space between the columns are easily joined. Stress is reliably transmitted between the column and the beam due to the adhesion resistance with the filler injected into the column and the compressive force between the sheath pipe and the column material through the filler.
