PROBLEM TO BE SOLVED: To provide a reinforced-concrete column-steel frame beam joining structure capable of firmly joining a reinforced concrete column becoming a lower floor column and a steel frame beam with excellent workability, and also large in bearing force of a column-beam joining part.SOLUTION: A reinforced-concrete column-steel frame beam joining structure for joining an upper end of a lower floor column composed of a reinforced concrete column 1 and a steel frame beam 3, comprises diaphragms 5 respectively positioned in a height position of upper-lower flanges 3a of the steel frame beam 3 and a joint part connection material 4 having a plurality of web joining parts 4a respectively joinable to a web 3b of the steel frame beam 3 by mutually connecting these upper-lower diaphragms 5. Concrete is filled in an inside space S enclosed by the plurality of web joining parts 4a of the joint part connection material 4.SELECTED DRAWING: Figure 6

【課題】下階柱となる鉄筋コンクリート柱と鉄骨梁とを作業性良く堅固に接合でき、かつ柱梁接合部の耐力が大きい鉄筋コンクリ−ト柱・鉄骨梁接合構造を提供する。【解決手段】鉄筋コンクリート柱１からなる下階柱の上端と、鉄骨梁３とを接合する鉄筋コンクリート柱・鉄骨梁接合構造である。鉄骨梁３の上下のフランジ３ａの高さ位置にそれぞれ位置するダイアフラム５と、これら上下のダイアフラム５を互いに連結し鉄骨梁３のウェブ３ｂとそれぞれ接合可能な複数のウェブ接合部位４ａを有する継手部連結材４とを備える。継手部連結材４の複数のウェブ接合部位４ａで囲まれた内部空間Ｓにコンクリートが充填される。【選択図】図６
