This invention is as described above, and an end plate is joined to each of the upper and lower flanges of a steel beam, and a rib is provided on the end plate on the extension line of the flange of the steel frame, and the end plate is joined to the side surface of the flange perpendicular to the rib. Since the flange is provided, it can provide sufficient strength against the tensile force and bending generated in the end plate, and because it is connected to the column with bolts through this, the number of bolts and parts can be reduced. As a result, the structure of the joint is simplified.
