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.SOLUTION: In a joining part structure 100 in which outside faces of columns 10, flat beams having beam widths Bg wider than column widths Bc, and orthogonal beams 30 orthogonal to the columns 10 and the flat beams are connected in flush with one another, 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 at the inside of column heights of the columns 10 including a joining part 40 between the columns 10 and the flat beams, and also at the outside of beam widths of orthogonal beams 30, and lateral U-shaped hairpin bars 33 extending from both sides of the columns 10 in extension directions toward the inside of the joining part 42 are arranged so as to surround the beam main pars 21 in the joining part 42 in a direction in which the orthogonal beams 30 extend in the joining part 42 between the flat beams and the orthogonal beams 30 at the outside of the columns 10.SELECTED DRAWING: Figure 1
【課題】配筋施工の簡易化、ねじり変形の抑制及び外端面におけるひび割れの発生の抑制を図る柱と扁平梁との接合部構造を提供する。【解決手段】柱１０と柱幅Ｂｃより広い梁幅Ｂｇを有する扁平梁と柱１０及び扁平梁と直交梁３０との外側面が面一に接続されている接合部構造１００であって、柱１０と扁平梁との接合部４０を含む柱１０の柱せいの内側で且つ直交梁３０の梁幅の外側において、扁平梁内に配置されている梁主筋２１を取り囲むように、２個に分割されコの字状からなる複数のねじり補強筋２２が、柱１０の柱幅の内側で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、柱１０の外側で扁平梁と直交梁３０との梁の接合部４２内において、接合部内４２の梁主筋２１を直交梁３０の延びる方向に囲むように、柱１０の延びる方向の面側から梁の接合部４２内方に向ってコの字状のかんざし筋３３が配置されている。【選択図】図１
