To provide a reinforcement connection part structure that reinforces particularly a part near an existing structure by fitting a joint metal for connecting a reinforcement member such as a frame bar to a connection part by non-welding on an existing steel frame member.SOLUTION: A reinforcement connection part structure is constituted by including a rectangular annular frame hardware 12 installed so as to surround a connection part 50a and a cement-based solidification material 17, which engulfs a steel frame member 52 and is placed in the inside of the rectangular annular frame hardware 12. A plurality of stud members 13 are fitted so as to protrude inward from an inside surface 12b of the rectangular annular frame hardware 12. The rectangular annular frame hardware 12 and the cement-based solidification material 17 are constructed by non-welding and fixed around the steel frame member 50 of the connection part 50a at a construction site. A reinforcement member 20 is connected by non-welding to a joint metal 11 of the rectangular annular frame hardware 12 and the reinforcement member 20 is integrally connected to the steel frame member 50.SELECTED DRAWING: Figure 3 【課題】既存の鋼製骨組み部材に、フレーム材等の補強部材が連結される接合金物を、無溶接で連結部分に取り付けて、特に既存の構築物に近接する部分において補強させる補強用連結部構造を提供する。【解決手段】連結部分５０ａの周囲を囲んで設置された矩形環状枠金物１２と、鋼製骨組み部材５２を巻き込んで、矩形環状枠金物１２の内側に充填されたセメント系固化材１７とを含んで構成される。矩形環状枠金物１２の内側面１２ｂから内側に突出して、複数のスタッド部材１３が取り付けられている。施工現場において、矩形環状枠金物１２及びセメント系固化材１７が、無溶接で施工されて連結部分５０aの鋼製骨組み部材５０の周囲に固設される。矩形環状枠金物１２の接合金物１１に補強部材２０が無溶接で連結されて、補強部材２０が鋼製骨組み部材５０に一体として接合される。【選択図】図３
