PROBLEM TO BE SOLVED: To provide a composite structure of a reinforced concrete column and a steel frame beam and its execution method in which a welding quantity can be reduced and workability can be improved, and the fitting work of the steel frame beam to the reinforcing concrete column can be rationalized, and the construction works can be advanced without need to wait for completion of the reinforced concrete column and hence, the construction period can be shortened. SOLUTION: A columnar temporary erection member 3a to be embedded in a reinforced concrete column 1 is erected in a construction position of the reinforcing concrete column 1, while temporarily supporting a plurality of steel frame beams 5a, 5b, 5c crossing with each other on the reinforced concrete column 1, and connection members 7a, 7b are arranged between mutual steel frame beams 5a, 5b, 5c crossing with each other on the columnar temporary erection member 3a. The connection members 7a, 7b and the steel frame beams 5a, 5b, 5c are connected to each other by high tension bolts 13, 19 in order to mutually connect steel frame beams 5a, 5b, 5c.
