BEAM-COLUMN JOINING PART STRUCTURE
To provide a joining part structure of columns and flat beams which can facilitate reinforcement arrangement construction, and can suppress torsional deformation and the generation of cracks at an outer end face of an overhanging part.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 which are divided into two pieces, respectively, and formed into lateral U-shapes are fixed to beam main bars 21 while both end parts formed into lateral U-shapes are overlapped on each other in directions of the column widths at the inside of the column widths of the columns 10 so as to surround a plurality of beam main bars 21 which are arranged in the flat beams 20 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, lateral U-shaped second reinforcements 26 composed of linear base parts 26a extending from flush outside face sides toward the inside of the flat beams 20, and two leg parts 26b extending from both end parts of the base parts 26a are arranged outside the column widths of the columns 10 out of the flat beams 20, and the two leg parts 26b are fixed to the torsion reinforcements 22, respectively, at portions intersecting with the plurality of torsion reinforcements 22.SELECTED DRAWING: Figure 1
【課題】配筋施工の簡易化、ねじり変形の抑制及び跳ね出し部の外端面におけるひび割れの発生の抑制を図ること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、２個に分割されてそれぞれコの字状からなる複数のねじり補強筋２２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に固定されており、扁平梁２０のうち柱１０の柱幅の外側において、前記面一となる外側面側から扁平梁２０内方に向って直線状の基部２６ａと基部２６ａの両端部から延びる２つの足部２６ｂとかなるコの字状の第２の補強筋２６が配置されており、２つの足部２６ｂは複数のねじり補強筋２２と交差する部分においてねじり補強筋２２にそれぞれ固定されている。【選択図】図１
