Highway bridge expansion joint structure
The invention relates to the technical field of bridge engineering, and discloses a highway bridge expansion joint structure which comprises a bridge body, a plurality of U-shaped steel bars at equal intervals are pre-embedded in the butt joint of the bridge body, and fixing steel bars are welded in the U-shaped steel bars. A butt joint steel bar is welded to the top of the fixing steel bar and located between the two U-shaped steel bars. According to the highway bridge expansion joint structure, the mud blocking assemblies are arranged between the butt joints between the bridge bodies, the sliding strips are fixedly installed at the bottoms of the mud blocking nets, the grooved wheels are arranged on one sides of the reinforcing steel bars, and the sliding strips are installed in the grooved wheels in a sliding mode, so that the mud blocking nets can move on the tops of the reinforcing steel bars; the problems that the installation process of a mud blocking net is tedious, cleaning is inconvenient, and the efficiency of maintaining and eliminating dirt of an expansion joint structure by workers is not high are solved, when the mud blocking net needs to be cleaned, the mud blocking net is pulled out from one side of the bridge body, and cleaning is convenient.
本发明涉及桥梁工程技术领域，且公开了一种公路桥梁伸缩缝结构，包括桥梁本体，所述桥梁本体的对接处的内部预埋有若干个的等间距的U型钢筋，所述U型钢筋的内部焊接有固定钢筋，所述固定钢筋的顶部且位于两个所述U型钢筋之间焊接有对接钢条。该公路桥梁伸缩缝结构，通过在桥梁本体之间的对接缝之间设置挡泥组件，通过在挡泥网的底部固定安装滑条，在加固钢条的一侧设置槽轮，将滑条滑动安装在槽轮的内部，使得挡泥网可以在加固钢条的顶部移动，解决了挡泥网安装过程较为繁琐，且清理不便，导致工作人员养护、消除伸缩缝结构的污物的效率不高的问题，需要清理挡泥网时，将挡泥网从桥梁本体的一侧抽出，方便进行清理。
