To provide a joint structure of a column and a beam capable of enhancing the frame rigidity.SOLUTION: A joint structure 100 of a column and a beam is a joint structure of an H-shaped steel beam and a column of a concrete filled steel tube structure that comprises a steel pipe 21 that extends in a vertical direction and is formed in a cylindrical shape, a main bar 22 that is arranged inside the steel pipe 21 and extends in the vertical direction, and a concrete section 23 that is filled inside the steel pipe 21. The joint structure is characterized by having an upper diaphragm 31 and a lower diaphragm 32 that are installed on an outer surface 21a of the steel pipe 21, have a contour that is circular in plan view, and are joined to upper and lower flanges 11, 12 of the beam 1, and a plurality of reinforcing materials 33 that protrude outward from the outer surface 21a of the steel pipe 21 and have their upper and bottom end parts joined to the upper diaphragm 31 and the lower diaphragm 32 respectively.SELECTED DRAWING: Figure 1 【課題】架構剛性を高めることができる柱と梁との接合構造を提供する。【解決手段】柱と梁との接合構造１００は、鉛直方向に延び、円筒形に形成された鋼管２１と、鋼管２１の内部に配置され、鉛直方向に延びる主筋２２と、鋼管２１の内部に充填されたコンクリート部２３と、を有するコンクリート充填鋼管造の柱とＨ形鋼の梁との接合構造であって、鋼管２１の外面２１ａに設けられるとともに外形が平面視円形状をなし、梁１の上下のフランジ１１，１２と接合される上部ダイアフラム３１及び下部ダイアフラム３２と、鋼管２１の外面２１ａから外側に突出し、上下端部がそれぞれ上部ダイアフラム３１及び下部ダイアフラム３２に接合された複数の補強材３３と、を備えることを特徴とする。【選択図】図１
