The invention relates to the technical field of highway bridges, in particular to an anti-seismic support for highway bridges, which comprises a bottom steel plate, a stop lever mechanism used on the bottom steel plate to facilitate seismic resistance of the bridge and a supporting mechanism used on the bottom steel plate to prevent the bridge from overturning, and the stop lever mechanism comprises a supporting seat, a fixed vertical rod and an upper seat plate. An arc-shaped buffering groove is formed in the upper end of the bottom steel plate, the supporting base is located on the inner side wall of the arc-shaped buffering groove, and the four fixing vertical rods are located at the four corners of the supporting base respectively. The positioning clamping block and the two supporting rods are arranged to be matched, when the two supporting rods rotate to leave the interior of the hidden groove to support the upper seat plate, a triangular shape is formed between the two supporting rods and the upper seat plate, a stable supporting structure is formed, the positioning clamping block can be clamped at the position of the supporting seat after being ejected out of the sliding rail, the supporting rods are effectively limited, and the stability of the supporting seat is improved. And the stability of supporting the upper seat plate by the two supporting rods is ensured.
本发明涉及公路桥梁技术领域，特别是涉及一种公路桥梁用抗震支座，包括底钢板，所述底钢板上使用便于对桥梁进行抗震的挡杆机构，所述底钢板上使用避免桥梁倾覆的支撑机构，所述挡杆机构包括支撑座、固定立杆和上座板，所述底钢板的上端部开设有弧形缓冲槽，所述支撑座位于弧形缓冲槽的内侧壁，所述固定立杆的数量为四个，四个所述固定立杆分别位于支撑座上的四角处。本发明通过设置了定位卡块和两个支撑杆相配合，在两个支撑杆转动离开隐藏槽内对上座板进行支撑时，两个支撑杆和上座板之间形成三角状，为一个稳定的支撑结构，定位卡块在弹出滑轨后可卡在支撑座处，对支撑杆进行有效的限位，保证两个支撑杆对上座板支撑的稳定性。
