Separating type multi-stage friction damping support
The invention provides a separated multi-stage friction damping support, and belongs to the technical field of bridge supports. The support comprises an upper support, a middle cover plate, a spherical crown lining plate and a lower support which are sequentially overlapped, the upper support is in sliding fit with the middle cover plate, the middle cover plate is in sliding fit with the spherical crown lining plate, and the spherical crown lining plate is in running fit with the lower support; an injection channel is formed in the spherical crown lining plate and used for injecting lubricating liquid, and an injection outlet of the injection channel is located in the side, facing the middle cover plate, of the spherical crown lining plate. The injection port of the injection channel is formed in the side, facing the middle cover plate, of the spherical crown lining plate, so that the lubricating liquid can lubricate the oppositely-arranged surfaces of the spherical crown lining plate and the middle cover plate, friction between the spherical crown lining plate and the middle cover plate is reduced, the support can adapt to normal displacement of a beam body, and the service life of the support is prolonged. And in addition, under the condition that an earthquake comes, the middle cover plate and the spherical crown lining plate can normally slide and are matched with the upper support to swing, and the earthquake force is dissipated.
本发明提供了一种分离式多级摩擦减震支座，属于桥梁支座技术领域。所述支座包括依次重叠设置的上支座、中间盖板、球冠衬板以及下支座，上支座与中间盖板滑动配合，中间盖板与球冠衬板滑动配合，球冠衬板与下支座转动配合；球冠衬板内部设置有注射通道，注射通道用于注射润滑液体，注射通道的注射出口位于球冠衬板朝向中间盖板的一侧。本发明通过将注射通道的注射口设置于球冠衬板朝向中间盖板的一侧，以使得润滑液体能够对球冠衬板以及中间盖板相向设置的表面润滑，从而减小球冠衬板和中间盖板的摩擦，使得支座能够适应梁体的常态位移，并且在地震来临的情况下，中间盖板与球冠衬板能够正常滑动，配合上支座进行摆动，对地震力进行耗散。
