Prestress multidirectional displacement bridge expansion device and mounting method thereof
The prestressed multidirectional displacement bridge expansion device comprises a fixed comb plate, a movable comb plate, an anchoring plate, a fixed plate and a damping connecting piece, the fixed plate is fixedly connected to the top of the anchoring plate and located at the top of the side wall of a beam end expansion joint, and the rear lower portion of the movable comb plate is installed on an installation notch in the top of the fixed plate through the damping connecting piece; gaps are reserved between the movable comb plate and the bottom wall and the side wall of the installation notch. The installation method of the prestressed multi-directional displacement bridge expansion device comprises the following steps: S1, welding the expansion device with an embedded anchoring rib in a reserved groove; s2, a concrete layer in the reserved groove is poured; s3, the temporary transition plate is replaced, and then an asphalt layer is paved; and S4, replacing the transition plate with a fixed comb plate and a movable comb plate, and fastening. According to the prestressed multidirectional displacement bridge expansion device and the mounting method thereof, the multidirectional displacement requirement of the bridge under the complex working condition can be well met, the mounting process is simplified, and the construction efficiency is improved.
本发明公开了一种预应力多向变位桥梁伸缩装置，包括固定梳齿板、活动梳齿板、锚固板、固定板和阻尼连接件，固定板固定连接在锚固板顶部且位于梁端伸缩缝的侧壁顶部，活动梳齿板后下方通过阻尼连接件安装到固定板顶部安装缺口上，活动梳齿板与安装缺口底壁和侧壁之间均留有缝隙。本发明预应力多向变位桥梁伸缩装置安装方法包括：S1、将伸缩装置与预留槽内预埋锚固筋焊接；S2、浇筑预留槽内混凝土层；S3、更换临时过渡板，然后摊铺沥青层；S4、将过渡板更换为固定梳齿板和活动梳齿板，并紧固。本发明预应力多向变位桥梁伸缩装置及其安装方法，能够较好的适应桥梁复杂工况下多向变位要求，安装工艺简化，提高了施工效率。
