PROBLEM TO BE SOLVED: To provide a steel column and column beam joint structure that do not require processing of the column itself, and can suppress deformation of a rounded part even when the rounded part exists between side surfaces of the column.;SOLUTION: A steel column 1 includes a column main body 2 in the form of, for example, a square steel pipe, and a flat-shaped support steel 3. Two adjacent surfaces of the column main body 2 are served as connection surfaces, and only the connection surfaces are provided thereon with the flat-shaped support steel member 3. The flat-shaped support steel member 3, which is vertically arranged in two piece structure, is provided on each of the connection surfaces, and in each of the supporting steel members 3, four bolt fastening tap holes 3a are formed in the horizontal direction orthogonal to the side surface of the column main body 2. An end plate 41 of a beam 4 is fixed to the support steel member 3. A bolt 5 is inserted into the bolt insertion hole of an end plate 41, and a screw part of the bolt 5 is screwed into the tap hole 3a of the support steel member 3.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2019,JPO&INPIT
