Combined disc spring sliding friction self-resetting energy dissipation damper
The invention discloses a combined disc spring sliding friction self-resetting energy dissipation damper, and belongs to the technical field of disaster prevention and shock absorption. Upper and lower wave-shaped outer sleeves and left and right wedge-shaped inner cores are made of high-strength steel. The left and right wedge-shaped inner cores are welded with left and right end plates respectively. Grooves matched with the wedge-shaped inner cores in shape are formed in the inner sides of the upper wave-shaped outer sleeve and the lower wave-shaped outer sleeve, and the wedge-shaped inner cores are placed in the grooves of the upper wave-shaped outer sleeve and the lower wave-shaped outer sleeve. The upper wave-shaped outer sleeve and the lower wave-shaped outer sleeve are connected together by high-strength bolts through an anchorage device, and a prepressing combined disc spring is strung on a high-strength bolt bar. According to the combined disc spring sliding friction self-resetting energy dissipation damper, the requirements for deformation and bearing capacity of the structure under the earthquake action can be met. The damper is simple in structure, clear in working mechanism and high in energy consumption performance and self-resetting performance. The problems that the post-earthquake maintenance and reconstruction cost is increased and the energy consumption capacity is insufficient due to excessive residual deformation of a common energy consumption damper under the action of a large earthquake or a medium earthquake can be solved.
一种组合碟簧滑移摩擦自复位耗能阻尼器，属于防灾减震技术领域。上下波浪形外套管和左右楔形内芯均为强度较高的钢材。左右楔形内芯分别与左右端板焊接。上下波浪形外套管内侧均有与楔形内芯形状吻合的凹槽，楔形内芯放置在上下波浪形外套管的凹槽里。高强螺栓通过锚具将上下波浪形外套管连接在一起，预压组合碟簧串在高强螺栓杆上。本发明可满足结构在地震作用下的变形和承载力要求。该阻尼器构造简单，工作机理明确，耗能性能与自复位性能能力强。本发明是为了解决普通耗能阻尼器在大震或中震作用下出现过量的残余变形而加大震后维护和重建成本以及耗能能力不足的问题。
