The invention belongs to the technical field of earthquake resistance and shock absorption of building construction, and particularly discloses a three-stage friction damper. The three-stage frictiondamper comprises an upper pressing plate, a lower pressing plate and a friction part; the friction part is in a U shape and is bonded to the bottom of the upper pressing plate through a bonding agent,bolt holes are formed in the upper pressing plate and the friction part in a penetrating mode, and built-in bolts are used for reinforcing connection; the lower pressing plate is provided with a three-step-table-shaped friction face, the joint of the step tables is arranged to be in an inverted circular bead shape, and the upper pressing plate is perpendicularly placed on the center friction faceof the lower pressing plate; and the three-step friction damper can work under small earthquakes, medium earthquakes and even large earthquakes, the working interval is large, the coverage range is wide, and damage of earthquakes to buildings can be effectively prevented, so that a perfect anti-seismic protection capability can be provided for all buildings.
本发明属于建筑施工抗震、减震技术领域，具体公开一种三阶段摩擦阻尼器，包括上压板、下压板和摩擦件，摩擦件呈U型状通过粘结剂粘结于上压板底部，并于上压板和摩擦件上贯穿设置有螺栓孔，内置螺栓进行加固连接，下压板设置三阶梯台型摩擦面，梯台连接处设置为倒圆角形，上压板垂直放置于下压板的中心摩擦面上，三阶摩擦阻尼器可以在小震、中震乃至大震下工作，工作区间大，覆盖范围广，可以有效的阻止地震对建筑物的破坏，能够为所有建筑物提供较完善的抗震防护能力。
