COLUMN-BEAM JUNCTION STRUCTURE

PROBLEM TO BE SOLVED: To provide a structure that prevents the destruction of a column-beam junction caused by deterioration of adhesion between concrete and a main reinforcement.SOLUTION: A column-beam junction structure includes a junction 10 having an arranged column main reinforcement 22 of a reinforced concrete column 20 and an arranged beam main reinforcement 32 of a reinforced concrete beam 30, and a bearing member (mechanical joint 40) to produce a bearing force, disposed on the column main reinforcement 22 or the beam main reinforcement 32.SELECTED DRAWING: Figure 1 【課題】コンクリートと主筋の付着力劣化に伴う柱梁の接合部の破壊を抑制する。【解決手段】柱梁の接合部構造は、鉄筋コンクリート製柱２０の柱主筋２２と鉄筋コンクリート製梁３０の梁主筋３２とが配筋された接合部材１０と、柱主筋２２又は梁主筋３２に設けられ支圧力を発生させる支圧部材（機械式継手４０）と、を有する。【選択図】図１
