PROBLEM TO BE SOLVED: To omit the welding work of the joint portion of a reinforcing bar and to simplify the arranging/assembling process for reinforcing bar. SOLUTION: A column steel frame 20 and a plurality of beam steel frames 30 intersect each other, column reinforcing bars are arranged around them to form a column-beam junction, reinforcing bars 3a-3d are arranged in a ring shape around the column-beam junction, and concrete 40 is placed on the outer periphery of the column-beam junction and the reinforcing bars 3a-3d. Deformed reinforcing bars form with irregularities on the surface are used for the reinforcing bars 3a-3d, the hole diameter of bore sections 16a-16d is set to 2.5-3 times the diameter of the reinforcing bars 3a-3d, the reinforcing bars 3a-3d are inserted into at least two bore sections 16a-16d to be overlapped from both directions of the bore sections 16a-16d, and the fixing length of the tips of the reinforcing bars 3a-3d over web steel sheets 15 is set to 5-10 times the diameter of the bore sections 16a-16d.
