<p><P>PROBLEM TO BE SOLVED: To provide a column-beam joint structure which improves beam end resistance and welds an iron frame column of an angular steel pipe and an iron frame beam of H-shaped steel. <P>SOLUTION: A joint part of an iron frame column 1 and a beam 3 includes an iron frame column-beam flange welding joint part and an iron frame column-beam web welding joint part. The iron frame column-beam flange welding joint part is a joint part in which a flange 2a of the beam, a plate-like member 10 joined outside thereof and a bevel part 4 comprised of a through-diaphragm 3 of the iron frame column 1 are perfectly penetrated and welded. The iron frame column-beam web welding joint part is a joint part in which the through-diaphragm 3 of the iron frame column 1 and an abutting part of a web 2b of the beam are welded. The plate-like member 10 is a tapered plate of which the thickness is reduced linearly from a thick portion to a thin portion, and fillet-welded to the beam flange 2a while having an appropriate length at a side of the beam, with a terminal portion at a side of the iron frame column-beam flange welding joint part as a thick portion subtracting a thickness of the flange 2a of the beam from a thickness of the through-diaphragm 3. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
