High-damping vibration and noise reduction multidirectional displacement comb plate type telescopic device
The invention discloses a high-damping vibration and noise reduction multidirectional displacement comb plate type telescopic device which is characterized in that the root of a movable comb plate is arranged on a high-damping multidirectional displacement support and anchored on an A beam body through a pre-buried bolt, and a fixed comb plate is arranged on a stainless steel sliding plate and anchored on a B beam body through a pre-buried bolt; the movable comb plate is arranged on the stainless steel sliding plate across the expansion joint and is in socket joint with the comb teeth of the fixed comb plate; the high-damping multidirectional displacement support is composed of a sealing plate, a rubber block and a bottom plate, is arranged on the A beam body through anchor bolts, and is supported at the root of the movable comb plate. Compared with the prior art, the multidirectional displacement vibration and noise reduction device has multidirectional displacement vibration and noise reduction functions such as longitudinal displacement and vertical rotation, is simple in structure and convenient to mount, well solves the vertical rotation problem of the elevated bridge, is particularly suitable for being used by urban elevated bridges and high-grade highways, and has a good application prospect.
本发明公开了一种高阻尼减振降噪的多向变位梳齿板式伸缩装置，其特点是活动梳齿板根部设置在高阻尼多向变位支座上，且由预埋的螺栓锚固在A梁体上，固定梳齿板设置在不锈钢滑板上，且由预埋的螺栓锚固在B梁体上，所述活动梳齿板跨伸缩缝设置在不锈钢滑板上，且与固定梳齿板的梳齿相互承插；所述高阻尼多向变位支座由封板、橡胶块和底板组成，且由锚固螺栓将其设置A梁体上，为支撑在活动梳齿板根部的高阻尼多向变位支座。本发明与现有技术相比具有纵向变位，竖向转动等多向变位减振降噪功能，结构简单、安装方便，较好的解决了高架桥梁的竖向转动问题，尤其适应城市高架桥梁和高等级公路使用，具有良好的应用前景。
