The invention relates to a new round plate rubber bearing, which comprises an upper embedded plate, an upper support plate, an upper seal plate, a support body, a lower seal plate, a lower support plate and a lower embedded plate. The support body is composed of a rubber body and a plurality of metal thin-walled components with a rotating surface. The upper pre-embedded plate and the upper support plate are anchored with the bridge, the upper seal plate is fixed with the upper support plate, the lower pre-embedded plate and the lower support plate are anchored with the pier and the support cushion of the pier, the lower seal plate is fixed with the lower support plate, and the support body is fixed between the upper seal plate and the lower seal plate. The thin-walled metal members with revolving surfaces are placed in the support body in a concentric circle centered on the center line of the support, and the rubber body encapsulates the thin-walled metal members and is filled in the support body. The structure of the present invention is simple and novel, and the ring buffer metal thin-walled member embedded in the support body can obviously enhance the bearing's ability to resist vertical deformation, and can also effectively play a shock absorption effect and improve the overall performance of the support.
【技术实现步骤摘要】
一种新型圆板式橡胶支座
本专利技术属于公路桥梁领域,具体涉及一种新型板圆式橡胶支座。
技术介绍
桥梁在道路交通中因其具有诸多优点而得到广泛使用。桥梁支座在桥梁结构中起着重要作用,它将支座上部的桥体重量、各种交通工具的重量、及其它载荷传递给桥墩,同时承受桥体在使用中的变形。随着经济与社会发展越来越快,桥梁的运输量显著增加,给桥梁支座的安全性带来挑战。在桥梁支座的安装与养护都能规范开展的情况下,一种常见的桥梁支座破坏方式为起到固定作用的机械紧固件,如螺栓、螺母等的松动、脱落。对于板式橡胶支座而言,在公路运输中重型货运车辆经过时,其会产生较大的竖向变形量。当这种变形量频繁发生时,支座就容易发生上述破坏,影响桥梁的正常使用。为此,设计一种具有更好抵抗竖向变形能力,同时仍具有良好抗震性的新型橡胶支座显得十分必要。
