Rotary friction energy dissipation self-resetting fabricated beam-column joint
The invention relates to the technical field of beam-column joints, in particular to a rotational friction energy dissipation self-resetting fabricated beam-column joint which comprises a fabricated steel column, a fabricated steel beam, a self-resetting structure and a connecting structure, and the self-resetting structure is arranged between the fabricated steel column and the fabricated steel beam and fixedly connected with the fabricated steel column and the fabricated steel beam through the connecting mechanism; the self-resetting structure comprises rotating T-shaped steel, rotating angle steel, a belleville spring group and a friction plate; the rotating T-shaped steel, the rotating angle steel and the belleville spring set are fixed together through bolts. On-site assembly is dry operation construction, the working procedure is simple, and the construction speed is high; the force transmission path at the joint is clear, the beam-end shearing force is borne by the beam, the rotating T-shaped steel and the rotating angle steel, the beam-end bending moment is transmitted by the cover plate, and the node stress is reliable; when an earthquake occurs, deformation and energy consumption of the structure can be concentrated at the connecting position, outward movement of the plastic hinge is achieved, after the earthquake, the structure is free of residual deformation, self-resetting can be achieved, and the structure function can be rapidly recovered by replacing damaged parts at the connecting position.
本发明涉及梁柱节点技术领域，具体涉及一种转动摩擦耗能自复位装配式梁柱节点，包括装配式钢柱、装配式钢梁、自复位结构和连接结构，自复位结构设置在装配式钢柱与装配式钢梁之间，通过连接机构固定连接到一起；自复位结构包括转动T型钢、转动角钢、碟形弹簧组和摩擦板；通过螺栓将转动T型钢转动角钢以及碟形弹簧组固定在一起。本发明现场装配均为干作业施工，工序简单，施工速度快；连接处传力路径明确，梁端剪力由梁、转动T型钢和转动角钢承担，梁端弯矩由盖板传递，节点受力可靠；遭受地震时，可将结构的变形和耗能集中在连接处，实现塑性铰外移，震后，结构无残余变形可实现自复位，并通过更换连接处的受损部件可以快速恢复结构功能。
