According to the first aspect of the present invention, there is provided a joint between a column and a beam, and a joint having a beam-joining bracket disposed at the joint, and a vertically extending joint above and below the joint. Steel pipe, a plurality of first joining rebars whose both ends are inserted into the upper and lower steel pipes through the connection part, and concrete filled into the steel pipe and the connection part. In the joint structure of a column and a beam, the ends of a plurality of second joint reinforcing bars are joined to the upper flange and the lower flange of the joint steel frame, and the ends are connected in the vertical axis direction in the upper and lower steel pipes. Since each is inserted, not only can the bending strength of the column be increased with simple equipment, but also the joint structure that is strong against the effect of external force even in the shear transfer of the joint can be made. In addition, it is possible to dispose a reinforcing bar also at the position where the steel beam is erected. , There is no need to increase the number of first reinforcing bars penetrating the Joint portion, first to further penetrate the Joint portion
Since it is not necessary to increase the diameter of the column for the purpose of increasing the reinforcing bar, cost can be avoided.
