Bridge friction support
The invention provides a beam friction support, and the support comprises an upper base plate, a lower base plate and a friction sliding block arranged between the upper base plate and the lower baseplate in a sliding mode; the friction sliding block is a rubber sliding block, and the upper end face and the lower end face of the rubber sliding block are planes so that the rubber sliding block canbe matched with the upper base plate and the lower base plate to form a plane friction pair. The sliding friction coefficient a between the rubber sliding block and the lower base plate is less thanthe sliding friction coefficient b between the rubber sliding block and the upper base plate. The support has the advantages of being prevented from being damaged, good in vibration reduction effect,simple in structure and the like.
本发明提供一种梁摩擦支座，包括上座板、下座板，以及滑设于上座板和下座板之间的摩擦滑动块，所述摩擦滑动块为橡胶滑动块，所述橡胶滑动块的上下端面为平面，以与所述上座板和所述下座板配合形成平面摩擦副；所述橡胶滑动块与所述下座板之间的滑动摩擦系数a小于所述橡胶滑动块与所述上座板之间的滑动摩擦系数b。本发明具有避免桥墩损坏、减振效果好，且结构简单等优点。
