A junction for connecting a steel member to a structural member, such as a beam in a steel framed construction to a column in a reinforced concrete construction, a steel framed concrete construction or a steel framed construction. Junction hardware connect to the steel member and a rod-like orthogonal metal connector is provided in concrete structural members. The elements are connected by tightening bolts or by screw joints through a coupler. Since the metal connector is in a form of rod, the concrete member has a high packing property. Field welding work is omitted by connecting the metal connector to the junction hardware by a bolt connection method or by a screw joint method to facilitate assembly. Furthermore, the intermediate portion of the metal connector may have a flat or curved shape or a metal connector orthogonal to the intermediate portion may have a passable through hole, and thus the bolt portion of both metal connectors are positioned at the same level as are the heights of the top ends of the steel beams intersecting at right angles.
