Multi-stage friction damper
The multi-stage friction damper comprises a friction plate, friction pressing plate assemblies symmetrically arranged on the front side and the rear side of the friction plate and a connecting assembly, each friction pressing plate assembly comprises at least one friction pressing plate, the friction plate and the friction pressing plates are connected through the connecting assembly, and the connecting assembly comprises an anti-loosening bolt, a left-handed nut and a right-handed nut. The anti-loosening bolt penetrates in from the friction pressing plate on one side, penetrates out from the friction pressing plate on the other side after passing through the friction plate, and is matched with the left-handed nut and the right-handed nut at the same time. The multi-stage friction damper has an interlocking anti-loosening function, the stability and the reliability are improved, the function of providing different friction damping forces in different earthquake stages is achieved, the requirements of wind vibration, small earthquakes, medium earthquakes and large earthquakes for the performance of the damper are considered, the purpose of multi-stage energy consumption is achieved, the application range of the friction damper is greatly widened, and the application range of the friction damper is widened. The structure is simple and reasonable, the space utilization rate is high, installation is convenient, and practicability is good.
本发明涉及一种多阶摩擦阻尼器，包括摩擦板、对称设置在摩擦板前后两侧的摩擦压板组件以及连接组件，摩擦压板组件包括至少一个摩擦压板，摩擦板、摩擦压板之间通过连接组件相连接，连接组件包括防松螺栓、左旋螺母以及右旋螺母，防松螺栓从一侧的摩擦压板穿入，经摩擦板后从另一侧的摩擦压板穿出，并同时与左旋螺母、右旋螺母相配合。本发明的多阶摩擦阻尼器具有互锁防松的功能，提高了稳定性和可靠性，且实现了不同地震阶段提供不同摩擦阻尼力的功能，兼顾了风振、小震、中震和大震对阻力器性能的要求，达到多阶耗能的目的，极大提高了摩擦阻尼器的应用范围，且结构简单合理，空间利用率高，安装方便，实用性好。
