PROBLEM TO BE SOLVED: To provide a junction structure of a steel-pipe column and a beam which improves rigidity of the steel-pipe column in a joint part with the beam while reducing thickness of the steel-pipe column. ! SOLUTION: In the junction structure of a steel-pipe column 10 and a beam 20, the steel-pipe column 10 is formed by hot molding, a plurality of beams are bonded to an outer side face of he steel-pipe column 10 and in a hollow internal part 12, a reinforcing member 30 is provided that reinforces the steel-pipe column 10. The reinforcing member 30 is a rectangular steel pipe 31 formed by hot molding, and the rectangular steel pipe 31 is formed in such a manner that its length in a length direction becomes equal to or more than a length of a web 22 in the beam 20 in a height direction, and includes a plurality of angular portions 32 in a radial direction. The angular portion 32 is fixed onto an inner side face 10b of the steel-pipe column 10 along a joint part between the steel-pipe column 10 a |
