Ring groove rivet connection pair of steel-concrete composite structure and riveting, dismounting and replacing method
The invention relates to a ring groove rivet connection pair of a steel-concrete composite structure and a riveting, dismounting and replacing method. A pre-tightening force cap is fixedly connected with a pre-embedded rivet rod and a fastening meshing section, the fastening meshing section is provided with a fastening ring groove, a stretching section is provided with a stretching stress ring groove, and a fracture groove is fractured under the action of axial tension of the stretching section; and the ring sleeve can freely move within the range of the fastening occlusion section. The riveting method comprises the steps of installation, extrusion and riveting fixing, and after riveting, the lantern ring and the fastening meshing section are in tight mechanical connection and never loosen. The replacing and detaching method comprises the steps of sleeve cutting, sleeve removing and sleeve ring reinstalling, and convenient replacement of the fastening component of the steel-concrete composite structure can be achieved. The ring groove rivet connection pair is simple in structure and clear in stress, shear-resistant connection between steel and concrete is achieved through the pre-buried rivet rod and the fastening meshing section, and a combined structure with good cooperative stress is formed; riveting, replacing and replacing steps of the ring groove rivet connecting pair are simple and convenient, and rapid construction, replacing and updating of the steel and concrete combined structure can be achieved.
本发明涉及一种钢‑混凝土组合结构的环槽铆钉连接副及铆接、拆换方法，本发明预紧力帽分别与预埋铆钉杆和紧固咬合段固结，紧固咬合段带有紧固环槽，拉伸段设有拉伸受力环槽，断裂槽在拉伸段轴向拉力作用下断裂，环套可在紧固咬合段范围内任意移动。铆接方法包括安装、挤压、铆接固定环节，铆接后套环与紧固咬合段紧密机械连接，永不松动。换拆方法包括割套、脱套、套环再装环节，可实现钢‑混凝土组合结构紧固部件的便捷更换。本发明环槽铆钉连接副结构简明、受力明确，通过预埋铆钉杆和紧固咬合段实现钢与混凝土间的抗剪连接，形成协同受力良好的组合结构；环槽铆钉连接副铆接及拆换步骤简便，可实现钢与混凝土组合结构的快速施工与拆换更新。
