Vertical vibration isolation support
The vertical vibration isolation support comprises a base plate, a plurality of disc type vibration isolators are arranged on the base plate, a sliding plate a is arranged between the lower surfaces of the disc type vibration isolators and the base plate, and the top faces of the disc type vibration isolators are connected with a support assembly. The vertical vibration isolation device has the beneficial effects that the sliding plate a is arranged between the disc type vibration isolator and the base plate, the disc type vibration isolator and the sliding plate a jointly form a vibration isolation layer, under excitation of a train, vertical fundamental frequency formed by the beam body and the support keeps away from a superior frequency section of train vibration, and therefore vertical vibration isolation is achieved; meanwhile, a plurality of disc type vibration isolators are arranged on the base plate, so that the disc type vibration isolators are connected in parallel, the bearing capacity of the support is improved, and the support can be used on a large-span continuous beam bridge.
本发明公开了一种竖向隔振支座，包括底座板，底座板上设置有若干盘式隔振器，且盘式隔振器的下表面与底座板之间设置有滑板a，盘式隔振器的顶面与支座组件连接。本发明的有益效果是：通过在盘式隔振器与底座板之间设置有滑板a，盘式隔振器和滑板a共同形成隔振层，在列车激励下，使梁体与支座形成的竖向基频避开列车振动的优势频率区段，从而实现竖向隔振；同时在底座板上设置有多个盘式隔振器，从而使其并联，提高了支座的承载能力，从而能在大跨连续梁桥上使用。
