Highway bridge integral type telescopic device and construction method thereof
The invention discloses a highway bridge integral type telescopic device and a construction method thereof. The highway bridge integral type telescopic device is composed of a spring joint crossing plate, an embedded steel plate and a water guide device. The spring joint-crossing plate is an elastic plate body integrally formed by carbon nanofiber reinforced polyurethane materials, the two ends of the elastic plate body are anchored to the first side beam end and the second side beam end through anchor bolts respectively, the elastic plate body is provided with a spring plate area and a joint-crossing plate area, the spring plate area is located at the first side beam end, and the joint-crossing plate area is located at the second side beam end. The joint-crossing plate area spans the beam end gap; the embedded steel plate is embedded at the bottom of the seam crossing plate area, and the embedded steel plate spans the beam end gap; the spring plate area comprises spring units which are arranged in parallel, and each spring unit is of a broken line connecting rod flexible hinge telescopic structure; the water guide device is arranged below the spring seam crossing plate and located at the position of the beam end gap. The structure has better anti-seismic performance, noise is effectively reduced, and rapid construction and replacement are achieved.
本发明公开了一种公路桥梁整体式伸缩装置及其施工方法，由弹簧跨缝板、内嵌钢板和导水装置构成；弹簧跨缝板是以纳米碳纤维增强聚氨酯材料整体成型的弹性板体，所述弹性板体在两端分别通过锚固螺栓锚固在第一侧梁端和第二侧梁端上，弹性板体具有一段弹簧板区和一段跨缝板区，弹簧板区处位于第一侧梁端上，跨缝板区跨越梁端间隙；内嵌钢板镶嵌在跨缝板区的底部，且由内嵌钢板跨越梁端间隙；弹簧板区是并联设置的各弹簧单元，弹簧单元为折线连杆柔性铰链伸缩结构；导水装置设置在弹簧跨缝板的下方，且处在梁端间隙所在位置处。本发明具有更好的抗震性能、有效降低噪音，实现快速施工和更换。
