JOINT STRUCTURE OF COLUMN AND FLAT BEAM
To provide a joint structure of a column and a flat beam, capable of suppressing torsional deformation that may occur in an overhanging portion projecting from the column of the flat beam.SOLUTION: There is provided a joint structure 70 of a column and a flat beam in which a reinforced concrete column 10 and a reinforced concrete flat beam 20 wider than a width of the column 10 are joined. The flat beam 20 includes a column width corresponding portion 22E corresponding to the width of the column, and projecting portions 22A and 22B projecting laterally from the column 10. The column width corresponding portion 22E is provided with a first upper end main reinforcement 41 and a first lower end main reinforcement 42. The projecting portions 22A and 22B are provided with a second upper end main reinforcement 43 and a second lower end main reinforcement 44. A first reinforcing bar 51 bridging the first upper end main reinforcement 41 and the second lower end main reinforcement 44, and a second reinforcing bar 55 bridging the first lower end main reinforcement 42 and the second upper end main reinforcement 43 cross each other inside the projecting portions 22A and 22B.SELECTED DRAWING: Figure 4
【課題】扁平梁の柱から張り出す張出し部に生じ得るねじれ変形を抑制できる、柱と扁平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の幅よりも広幅の鉄筋コンクリート製の扁平梁２０とが接合される、柱と扁平梁の接合構造７０であり、扁平梁２０は、柱の幅に対応する柱幅相当部２２Ｅと、柱１０よりも側方に張出す張出し部２２Ａ，２２Ｂとを備え、柱幅相当部２２Ｅには、第１上端主筋４１と第１下端主筋４２が設けられ、張出し部２２Ａ，２２Ｂには、第２上端主筋４３と第２下端主筋４４が設けられており、第１上端主筋４１と第２下端主筋４４に跨がる第１補強筋５１と、第１下端主筋４２と第２上端主筋４３に跨がる第２補強筋５５が張出し部２２Ａ，２２Ｂの内部で交差している。【選択図】図４
