PROBLEM TO BE SOLVED: To provide a structure of welding and joining a column and beam, in which a diaphragm installed on a steel column and a flange end of a steel beam are joined together by butt welding, which enables a butt-welded joint between a beam flange and the diaphragm to be reinforced by a simple constitution, and which can surely prevent a fracture of the beam flange against bending moment. SOLUTION: An angle steel 11b is elongated from a butt-welded part 7 to the side of the steel beam, and attached, fillet welded and fixed to the beam flange 2a of the steel beam 2, and an angle steel 11a is fixed by fillet welding and fixed to the through-diaphragm 3 by fillet welding on the steel column-side. Furthermore, the angle steel 11b on the steel beam-side and the angle steel 11a on the steel column-side are connected by an L-shaped reinforcement plate 10, to reinforce the welded joined part 7 of the beam flange 2a end.
