The invention discloses a supporting type staged friction damper, and relates to the technical field of vibration control building dampers. The supporting type staged friction damper comprises a cross-shaped steel plate and L-shaped steel plates, first groove-shaped holes are formed in one sides of four wing plates of the cross-shaped steel plate, and second groove-shaped holes are formed in the other sides of the four wing plates of the cross-shaped steel plate; the four groups of L-shaped steel plates are connected with the cross-shaped steel plate in a matched mode in the mode that corners face the axis of the cross-shaped steel plate; each group of L-shaped steel plates comprises a first L-shaped steel plate and a second L-shaped steel plate; round holes are formed in the first L-shaped steel plate and the second L-shaped steel plate, high-strength bolts penetrate through the groove-shaped holes and the round holes matched with the groove-shaped holes, and the L-shaped steel plates are fixed to the cross-shaped steel plate; and friction elements are arranged on the attaching faces of the cross-shaped steel plate and the L-shaped steel plates. According to the supporting type staged friction damper, friction damping force can be provided by a plurality of friction surfaces, the energy consumption efficiency is higher, the assembly efficiency is high, the machining feasibility is high, and graded energy consumption is achieved.
本发明公开了一种支撑型分阶段摩擦阻尼器,涉及振动控制的建筑用阻尼器技术领域。包括十字型钢板和L型钢板，在十字型钢板的四条翼板上均一侧设置第一槽型孔，另一侧设置第二槽型孔；L型钢板有四组，均以拐角朝向十字型钢板轴心的方式与十字型钢板配合连接；每组L型钢板均包含第一L型钢板和第二L型钢板；第一L型钢板和第二L型钢板均设有圆形孔，高强螺栓穿过槽型孔及与其配合的圆形孔，将L型钢板固定在十字型钢板上；在十字型钢板和L型钢板的贴合面设置摩擦元件。本发明可以实现多个摩擦面提供摩擦阻尼力，耗能效率更高、装配效率高、加工可行性强并兼具分级耗能的优点。
