JOIN STRUCTURE OF BEAM STEEL MEMBER AND COLUMN REINFORCEMENT

PROBLEM TO BE SOLVED: To arrange many column reinforcements and ensure the strength on a beam steel member side when attaching many column reinforcements to a beam steel member. SOLUTION: A joint bracket 10 for reinforcement is fixed to a column reinforcement fixation position on an outer face of the beam steel member 2, and a tip of the column reinforcement 12 is preferably attached to the joint bracket to join the column reinforcement with the beam steel member. It is desirable that a reinforcing member 8 is attached to an inner face 5 in the vicinity of the column reinforcement fixation position of the beam steel member. It is preferable that the reinforcing member is attached by making it agree with the arrangement of column reinforcement or substantially in parallel. The beam steel member is made of H-steel, and the reinforcing member is preferably composed of the inner face 5 of a beam flange 3 in the vicinity of column reinforcement fixation position of H-steel, a beam web 6 continuous with the inner face, and a whole face reinforcing plate 8 welded on an inner face of a beam flange continuous with the beam web and on the opposite side. When the column reinforcement is a column reinforcement of a steel frame reinforced concrete column, it is preferable that the reinforcing member is attached to an outer side than the arrangement of the column reinforcement centered on a column.
