Bolt-free friction damping device
The invention discloses a bolt-free type friction damping device, and relates to the technical field of building damping. The bolt-free type friction damping device mainly comprises a friction steel plate, pressing blocks, constraint blocks, elastic bodies, fixing blocks and friction materials, the number of the friction steel plate is one less than that of the pressing blocks, the friction steel plate is laminated between the fixing blocks, the fixing blocks are placed in the pressing blocks with grooves, layers of the elastic bodies are arranged between the pressing blocks and the fixing blocks, and the strip-shaped friction materials are installed between the friction steel plate and the fixing blocks, stiffening ribs and connecting plates are welded at one ends of the pressing blocks, pin shaft holes are formed in the end parts of the friction steel plate and the connecting plates, the restraining blocks slide into the two sides of the pressing blocks with the steps, resilience force generated by extruding the elastic bodies is locked, and the pressing blocks and the restraining blocks are fastened through bolts. Compared with the mode that a bolt provides pre-tightening force, the problem that the bolt is loosened after being fastened for a long time is solved, and the performance is more stable; the damping device is simple in structure, low in price, convenient to maintain and replace, stable in performance and adjustable in friction force.
本发明公开了一种无螺栓型摩擦阻尼装置，涉及建筑减震技术领域，主要包括摩擦钢板、压块、约束块、弹性体、固定块及摩擦材料；摩擦钢板的数量比压块少一块夹在固定块之间叠层排布；固定块放置于带有凹槽的压块内，压块与固定块间设置一层弹性体，摩擦钢板与固定块间安装有条形摩擦材料；压块的一端焊有加劲肋和连接板；摩擦钢板与连接板的端部均开有销轴孔；约束块滑入带有台阶的压块的两侧，锁定挤压弹性体所产生的回弹力，并用螺栓将压块与约束块紧固起来。本发明与螺栓提供预紧力方式相比，不会出现螺栓长时间紧固发生松动问题，性能更稳定；该阻尼装置结构简单、价格低廉、维修更换方便，性能稳定且摩擦力可调节。
