JOINT STRUCTURE OF COLUMN, FLAT BEAM AND ORTHOGONAL BEAM
To provide a joint structure of a column, a flat beam and an orthogonal beam capable of suppressing torsional deformation which may be generated in an overhang part of the flat beam while reducing the amount of reinforcing bars required for reinforcing the overhang part as much as possible.SOLUTION: In a joint structure 200 of a column, a flat beam, and an orthogonal beam, a reinforced concrete-made column 10, a reinforced concrete-made flat beam 20 overhanging from the column 10 to its periphery, and a reinforced concrete-made orthogonal beam 30 orthogonal to the flat beam 20 are joined; in the overhang 25 in the area where the orthogonal beam 30 does not extend out of the flat beam 20, the beam main reinforcement 40 of the orthogonal beam 30 extends out, and at least a plurality of beam main reinforcing bars 40 are surrounded by square-shaped torsion reinforcing bars 50,55 in the overhang part 25.SELECTED DRAWING: Figure 3
【課題】張り出し部の補強に要する鉄筋量を可及的に低減しながら、扁平梁の張り出し部に生じ得るねじれ変形を抑制できる、柱と扁平梁と直交梁の接合構造を提供すること。【解決手段】鉄筋コンクリート製の柱１０と、柱１０からその周囲に張り出している鉄筋コンクリート製の扁平梁２０と、扁平梁２０に直交する鉄筋コンクリート製の直交梁３０とが接合されている、柱と扁平梁と直交梁の接合構造２００であり、扁平梁２０のうち、直交梁３０が延びていない領域における張り出し部２５には、直交梁３０の梁主筋４０が延びており、張り出し部２５において、少なくとも複数の梁主筋４０をロの字状のねじれ補強筋５０，５５が囲繞している。【選択図】図３
