<P>PROBLEM TO BE SOLVED: To provide a column-beam joint structure which has superior beam end bearing force, and has an iron frame column of H-shaped steel, I-shaped steel, etc., having parallel flanges at its top and bottom welded to a steel frame column such as a square steel pipe column, a welding box column, etc. <P>SOLUTION: A joint part of an iron frame column and a beam includes an iron frame column beam flange weldbonding part and an iron frame column beam web weldbonding part. The iron frame colum beam flange weldbonding part is a joint part formed by welding the flanges of the beam and a beveled part comprising plate-like members joined outside them and a through diaphragm of the iron frame column in a complete penetration manner, and the iron frame column beam web weldbonding part is a joint part formed by welding an abutment part between the iron frame column and a web of the beam. The web of the beam is provided with a scallop for welding the iron frame column beam flange weldbonding part, and the plate-like member has a plate thickness obtained by subtracting the plate thickness of the flanges of the beam from the through diaphragm, a plate thickness substantially equal to the flange width of the beams, and a suitable length on the opposite side from the iron frame column beam flange weldbonding part, and is bolt-connected to the beam flanges with a high strength bolt. <P>COPYRIGHT: (C)2013,JPO&INPIT |
