To provide a joining part structure of columns and flat beams which can facilitate reinforcement arrangement construction, and can suppress torsional deformation.SOLUTION: In a joining part structure 100 of columns 10 and flat beams 20 having beam widths Bg wider than column widths Bc of the columns 10, a plurality of torsion reinforcements 22 are arranged in the flat beams 20 so as to surround a plurality of beam main bars 21 which are arranged in the flat beams 20 at the inside of column heights of the columns 10 including a joining part 30 between the columns 10 and the flat beams 20, each of the torsion reinforcements 22 is divided into two pieces, the two pieces are formed into lateral U-shapes, and the plurality of torsion reinforcements which are divided into two pieces, respectively, and formed of the lateral U-shapes are fixed to the beam main bars 21 while being overlapped on one another at lateral U-shaped both end parts in directions of the column widths at the inside of the column widths of the columns 10.SELECTED DRAWING: Figure 1 【課題】配筋施工の簡易化及びねじり変形の抑制が可能な柱と扁平梁との接合部構造を提供する。【解決手段】柱１０と柱１０の柱幅Ｂｃより広い梁幅Ｂｇを有する扁平梁２０との接合部構造１００であって、柱１０と扁平梁２０との接合部３０を含む柱１０の柱せいの内側において、扁平梁２０内に、扁平梁２０内に配置されている複数の梁主筋２１を取り囲むように複数のねじり補強筋２２が設けられており、各ねじり補強筋２２は２個に分割されてそれぞれコの字状からなり、２個に分割されてそれぞれコの字状からなる複数のが、柱１０の柱幅の内側において、コの字の両端部が柱幅の方向に重複して梁主筋２１に固定されている。【選択図】図１
