The invention relates to the technical field of bridge seismic resistance, and discloses an anti-seismic device for a highway bridge. The anti-seismic device for the highway bridge comprises a bridge body supporting base and two bridge bottom fixing plates on the bridge body supporting base, the two bridge bottom fixing plates are used for being symmetrically installed at the butt joint position of the bridge, fixing holes are formed in the upper ends of the bridge bottom fixing plates, symmetrical clamping plates are installed on the bridge body supporting base, and the symmetrical clamping plates are arranged on the bridge body supporting base. And a transverse buffering structure is installed on one side of the symmetrical clamping plates and comprises a supporting inner sleeve, a sliding inner shaft and a connecting supporting lug, the sliding inner shaft is installed in the supporting inner sleeve, and the connecting supporting lug is installed at one end of the sliding inner shaft. According to the shock absorption bridge, the tightening force of mutual gathering between the two bridge bottom fixing plates is improved, so that when the bridge body is in a shock condition, supporting shock absorption can be provided, meanwhile, the acting force of inward gathering can be provided between the two bridge bodies, and the situation that after the two bridge bodies are shocked, the connecting position is broken by a large distance can be avoided.
本发明涉及桥梁抗震技术领域，且公开了一种公路桥梁用抗震装置。该公路桥梁用抗震装置包括桥身支撑底座和桥身支撑底座上的桥底固定板，桥底固定板有两个，桥底固定板用于对称安装在桥梁对接处，桥底固定板的上端设有固定孔，桥身支撑底座的上安装有对称夹板，对称夹板的一侧安装有横向缓冲结构，横向缓冲结构包括支撑内套、滑动内轴和连接支耳，支撑内套的内部安装有滑动内轴，滑动内轴的一端安装有连接支耳。本发明提高两个桥底固定板之间的相互聚拢的收紧力，使得桥身在发生震动状况时，不仅能提供支撑减震的同时，还能为两段桥身之间提供向内收拢的作用力，可避免两段桥身收到震动后，连接处出现较大距离的断离状况。
