COLUMN-BEAM CONNECTION STRUCTURE

PROBLEM TO BE SOLVED: To provide a column-beam connection structure that enables a beam to be efficiently welded on a column-beam connection.SOLUTION: End face parts of through-diaphragms 2, 3 disposed on a column-beam connection 1 that connects a column 10 and beams 4, 5 comprise a first end face part A having a first projection amount and a second end face part B having a second projection amount that is smaller than the first projection amount. A beam depth of the beam 5 is smaller than a vertical distance between the through-diaphragms 2, 3. An upper flange 5a is welded and fixed on the first end face part A and a lower flange 5b is welded and fixed at a position displaced from the second end face part B toward a body side of the column-beam connection 1.SELECTED DRAWING: Figure 1 【課題】柱梁接合部に梁を効率的に溶接できる柱梁接合構造を提供する。【解決手段】柱１０と梁４、５を接合する柱梁接合部１に設けられている通しダイアフラム２、３の端面部として、第１の突出量である第１端面部Ａと、上記第１の突出量よりも小さい第２の突出量を有する第２端面部Ｂとが在る。上記通しダイアフラム２、３の上下間距離よりも梁せいの低い梁５は、上側フランジ５ａが上記第１端面部Ａに溶接固定され、下側フランジ５ｂが上記第２端面部Ｂから上記柱梁接合部１の本体側にずれた位置に溶接固定されている。【選択図】図１
