PROBLEM TO BE SOLVED: To provide a joint reinforcement structure capable of reducing the effect of input heat on a welding base metal while maintaining high welding efficiency. SOLUTION: A flat steel plate joint reinforcement plate 4 which surrounds the peripheral surface of a square steel-pipe column 1 is installed on the outer peripheral surface of the square steel-pipe column 1 at a column-beam joint part 3 where a beam member 2 is joined to the square steel-pipe column 1. Flat steel plates 5, 6, 7, 8 forming the joint reinforcement plate 4 are welded to each other, and the joint reinforcement plate 4 is welded to the square steel-pipe column 1.
