MANUFACTURING METHOD OF COLUMN-BEAM JOINT STRUCTURE AND COLUMN-BEAM JOINT STRUCTURE

摘要

To provide a manufacturing method of a column-beam joint structure and a column-beam joint structure which can prevent enlargement of a column cross section due to increase of a flexure width of the beam by removing a need of having a large cutout of a flange of the beam, can reduce a steel material weight and is cost-effective.SOLUTION: In a column-beam joint structure 1, a plurality of thick parts 3, a cutout 7 and a fine width part 5 in a central side of a flange plate are integrally formed (divided) and cut by a cutting line 8 and the thick part 3 is welded and connected to a column 2a.SELECTED DRAWING: Figure 1
