Self-adaptive multi-directional displacement tooth correction type bridge expansion device
The invention discloses a self-adaptive multi-directional displacement tooth correction type bridge expansion device which comprises a bearing unit, a tooth correction unit and a tooth correction unit, the bearing unit comprises a pier and a supporting seat fixedly connected to the upper surface of the pier, the upper surface of the supporting seat is fixedly connected with a first concrete bridge plate, and the upper surface of the supporting seat is fixedly connected with a second concrete bridge plate; and the displacement telescopic unit comprises a rubber plate fixedly connected to the upper surface of the first concrete bridge plate and a steel sliding plate fixedly connected to the upper surface of the rubber plate, a sliding groove is formed in the second concrete bridge plate in a hollowed-out mode, and a sliding block is slidably connected into the sliding groove. By adopting the tooth correction type structural design, the close fit between the fixed tooth plate and the insertion tooth plate and the buffering effect of the rubber buffering tooth plate, the connection stability of the bridge joint is effectively enhanced, displacement and vibration caused by temperature changes, earthquakes and the like are reduced, and therefore the service life of a bridge is prolonged.
本发明公开了一种自适应多向变位的校齿型桥梁伸缩装置，包括：承重单元，其包括桥墩以及固定连接在桥墩上表面的支撑座，所述支撑座上表面固定连接有第一混凝土桥板，所述支撑座上表面固定连接有第二混凝土桥板；变位伸缩单元，其包括第一混凝土桥板上表面固定连接有橡胶板以及固定连接在橡胶板上表面的钢制滑板，所述第二混凝土桥板内镂空设置有滑动槽，所述滑动槽内滑动连接有滑动块。本发明通过采用校齿型结构设计，固定齿板与插入齿板之间的紧密配合，以及橡胶缓冲齿板的缓冲作用，有效增强了桥梁接缝处的连接稳定性，减少了因温度变化、地震等引起的位移和振动，从而延长了桥梁的使用寿命。
