Ultra-shallow-buried comb plate bridge expansion device
The invention discloses an ultra-shallow-buried comb plate bridge expansion device. The device comprises a beam end and an expansion joint notch. The device is characterized in that: the upper surface of a fixed comb plate (4) is flush with the upper surface of a movable comb plate (7), the fixed comb plate (4) and the movable comb plate (7) are mutually crossed and meshed at a joint through a comb structure, and the upper surface of the fixed comb plate (4) and/or the upper surface of the movable comb plate (7) are/is provided with a plurality of grout overflow holes (5) penetrating through the comb plates. or a grout overflow hole (5) is additionally formed in the upper surface of a dustproof metal plate (6) and located in a movable telescopic area between the fixed comb plate (4) and the movable comb plate (7). The device is reasonable in structure and convenient to install, the compactness of concrete can be guaranteed, the technical problems of the compactness and flatness of the concrete of the bridge telescopic device are ingeniously solved, and the flatness of the connection between a telescopic panel and a bridge deck can also be guaranteed. Meanwhile, the anti-shearing capability of the comb plate is also improved, and exhausting, packaging and drilling sampling are facilitated.
一种超浅埋梳齿板桥梁伸缩装置，包括梁端和伸缩缝槽口，其特征在于：所述固定梳齿板（4）和活动梳齿板（7）的上表面相平，并且固定梳齿板（4）与活动梳齿板（7）在接缝处通过梳齿结构相互交叉咬合，固定梳齿板（4）和/或活动梳齿板（7）的上表面开设有多个贯穿梳齿板的溢浆孔（5）；或者在防尘金属板（6）的上表面且位于固定梳齿板（4）与活动梳齿板（7）之间的活动伸缩区域内增加开设有溢浆孔（5），本发明结构合理，安装方便，不仅能够保证混凝土的密实度，巧妙地解决了桥梁伸缩装置混凝土密实度和平整度的技术难题，而且也能保证伸缩面板与桥面衔接的平整度，同时还提高了梳齿板的抗剪切能力，并有利于排气、打包和钻孔取样。
