The invention discloses a friction shock absorption support with multiple sliding surfaces, and belongs to the field of bridge shock absorption and isolation supports. The lower surface of the upper support plate is a convex face with the curvature radius of R1, and the upper sliding plate is tightly attached and fixed to the lower surface of the upper support plate. The upper surface of the lining plate is provided with a curved concave surface with the curvature radius of R1, the lower surface of the lining plate is provided with a curved protrusion with the curvature radius of R2, and the side face of the lining plate is an inclined face. The upper wear-resisting plate, the lower wear-resisting plate and the inclined wear-resisting plate are tightly attached and fixed to the upper surface, the lower surface and the side face of the lining plate respectively. And a concave surface is arranged on the upper surface of the lower support plate and comprises a lower support edge inclined surface and a lower support middle curved surface with the curvature radius of R2. And the lower sliding plate is tightly attached and fixed in the concave surface of the upper surface of the lower support plate. Curved surface sliding friction pairs are respectively formed between the upper wear-resisting plate and the upper sliding plate, between the middle curved surface of the lower sliding plate and the lower wear-resisting plate and between the edge inclined surface of the lower sliding plate and the inclined wear-resisting plate, and earthquake energy dissipation and buffering limiting are realized through the arrangement of multiple sliding surfaces.
本发明公开了一种含多滑动面的摩擦减震支座，属于桥梁减隔震支座领域。上支座板的下表面为曲率半径为R1的凸面，上滑动板紧密贴合固定在上支座板下表面。衬板上表面设有曲率半径为R1的曲面凹面，下表面设有曲率半径为R2的曲面凸起，侧面为斜面。上耐磨板、下耐磨板和斜耐磨板分别紧密贴合固定在衬板的上表面、下表面和侧面。下支座板上表面设有凹面，包括下支座边缘斜面和曲率半径为R2的下支座中间曲面。下滑动板紧密贴合固定在下支座板上表面凹面中。上耐磨板和上滑动板之间、下滑动板中间曲面和下耐磨板之间以及下滑动板边缘斜面和斜耐磨板之间分别构成曲面滑动摩擦副，通过多滑动面的设置实现耗散地震能量及缓冲限位。
