To improve conveyance easiness and site workability of a joint to be used for a column-beam structure of a steel frame building.SOLUTION: A joint 30 for coupling a lower floor pillar 20 and an upper floor pillar 40 comprises: a frame body 31; a bolt 341 penetrating a frame body side surface; and a solid part 36 obtained by filling expansive concrete inside the frame body and curing the expansive concrete. A composite beam 50 comprises: a beam body made from H-shaped steel; and a connection plate 55 welded to each of both ends in an extension direction of the beam body. On the connection plate 55 is formed an open hole 56 for penetration of a bolt. The joint 30 is fixed to an upper end of the lower floor pillar 20. The bolt 341 is then penetrated through the open hole 56 of the connection plate 55 and a nut 35 is fitted to the bolt. After that, the connection plate 55 and the frame body 31 are welded and joined.SELECTED DRAWING: Figure 3 【課題】鉄骨建築物の柱梁構造に用いる継ぎ手の運搬容易性と現場作業性を改善すること。【解決手段】下階柱２０及び上階柱４０を連結する継ぎ手３０は、枠体３１と枠体側面を貫通するボルト３４１と、枠体の内部に膨張コンクリートを充填して硬化させた充実部３６とを備える。合成梁５０は、Ｈ形鋼からなる梁本体と、梁本体の延伸方向の両端部のそれぞれに溶接された仕口プレート５５と、を備え、仕口プレート５５はボルトを貫通させるための貫通孔５６が形成される。下階柱２０の上端に継ぎ手３０を固定し、仕口プレート５５の貫通孔５６にボルト３４１を貫通させてナット３５をはめ合わせ、仕口プレート５５と枠体３１とを溶接して接合する。【選択図】図３
