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 cotters 33 that protrude inward from an inner surface 21d of the steel pipe 21.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の内面２１ｄから内側に突出する複数のコッタ３３と、を備えることを特徴とする。【選択図】図１
