To provide a column beam joint structure that can reduce the risk of damage such as cracks occurring at the joint where a flat beam and an orthogonal beam intersect due to twisting that occurs between the flat beam and the orthogonal beam during an earthquake or the like.SOLUTION: In a joint structure 100, a column 10, a flat beam 20 having a beam width wider than a column width of the column 10, and an orthogonal beam 30 that is orthogonal to the column 10 and the flat beam 20 and has beam width of less than or equal to the width of the beam are connected. There are arranged a plurality of beam main reinforcements 31 extending linearly in the longitudinal direction of the orthogonal beam 30 throughout the orthogonal beam 30 continuously through an overhanging portion 41 which is the joint portion with the flat beam 20 inside of the column 10 and the orthogonal beam 30 and a plurality of auxiliary bars 33 protruding from the outside of the beam width of the flat beam 20 into the orthogonal beam 30 through the overhanging portion 41 from the column 10 and extending linearly in the longitudinal direction of the orthogonal beam 30.SELECTED DRAWING: Figure 1 【課題】地震時などにおいて扁平梁と直交梁との間に生じるねじれによって、扁平梁と直交梁とが交叉する接合部にひび割れなどの破損が生じるおそれを低減することが可能な柱梁接合部構造を提供する。【解決手段】接合部構造１００は、柱１０と、柱１０の柱幅より広い梁幅を有する扁平梁２０と、柱１０及び扁平梁２０と直交し、梁幅が梁せい以下である直交梁３０とが接続されている。柱１０と直交梁３０との内部を扁平梁２０との接合部である張り出し部４１を介して連続的に直交梁３０の全体に亘って直交梁３０の長手方向に直線状に延びる複数の梁主筋３１と、柱１０から張り出し部４１を介して扁平梁２０の梁幅の外側から直交梁３０の内部に突出して直交梁３０の長手方向に直線状に延びる複数の補助筋３３とが配筋されている。【選択図】図１
