Fabricated comb tooth expansion joint and construction method thereof
The fabricated comb tooth expansion joint comprises beam end parts located on the two sides of the expansion joint, profile steel assemblies are installed on the beam end parts, the two profile steel assemblies are oppositely arranged, and the profile steel assemblies are connected with the corresponding beam end parts through a plurality of anchor bolt assemblies; the supporting components and the U-shaped stiffening ribs are further bonded to the corresponding beam ends through ultra-high-performance filling materials, the comb plate is flush with the top of the road surface, a cavity defined by the supporting components, the comb plate, the road surface and the beam ends is filled with the ultra-high-performance filling materials, and a plurality of leveling screw holes are further formed in the top of the comb plate. The leveling screw holes are located between every two adjacent U-shaped stiffening ribs. The expansion joint has the beneficial effects that the profile steel assemblies and the beam ends form a whole through the high-strength bolts and the ultra-high-performance filler, so that the expansion joint is high in structural strength and better in anti-fatigue performance, the service life is prolonged, and the profile steel assemblies are convenient to install; the whole construction period is short, the traffic efficiency is improved, and the assembly is simple.
本发明公开了装配式梳齿伸缩缝及其施工方法，包括位于伸缩缝两侧的梁端部，梁端部上均安装有型钢组件，两型钢组件相对设置，且型钢组件通过多个锚栓组件与对应梁端部连接，支撑构件和U形加劲肋还通过超高性能填充料粘接在对应梁端部上，梳齿板与路面的顶部齐平，支撑构件、梳齿板、路面和梁端部所围成的空腔内通过超高性能填充料填充，梳齿板的顶部还开设有若干调平螺孔，调平螺孔位于两相邻U形加劲肋之间。本发明的有益效果是：型钢组件通过高强螺栓及超高性能填充料与梁端部形成一个整体，使得伸缩缝结构强度高，抗疲劳性能更好，从而延长了使用寿命，且型钢组件安装方便；整个施工周期短，提高了通车效率，且装配简单。
