The invention discloses a bridge multidirectional resetting device which comprises at least three stop blocks, anchor rods, upper dowel bars, lower dowel bars, extrusion blocks, sleeves, belleville springs and screws, each stop block corresponds to one extrusion block, the stop blocks are mounted on a bridge pier, one end of each anchor rod is pre-buried in a main beam, each upper dowel bar is rotatably mounted on the anchor rod, and each lower dowel bar is rotatably mounted on the corresponding sleeve. Each upper dowel bar is rotationally connected with an extrusion block, each extrusion block is rotationally connected with a lower dowel bar, the anchor rod is sleeved with the sleeve, the sleeve is located below the upper dowel bars, and the other end of each lower dowel bar is rotationally connected with the lower portion of the sleeve; the screw rod is installed on the anchor rod through a thread matched with the anchor rod, and the belleville spring is arranged on the screw rod and the anchor rod in a sleeved mode. According to the multi-directional resetting device for the bridge, the relative displacement between the main beam and the bridge pier in any direction is limited and reset; the structure is simple and not easy to damage; under an earthquake, the anchor rod can prevent the beam from falling off, and components outside the anchor rod can be replaced; the lever effect is achieved; the influence on the overall stress of the bridge is small.
本发明公开一种桥梁多向复位装置，包括至少三块挡块、锚杆、上传力杆、下传力杆、挤压块、套筒、碟形弹簧和螺杆，每块挡块对应一块挤压块，挡块安装在桥墩上，锚杆一端预埋在主梁内，在锚杆上分别转动安装各上传力杆，每根上传力杆上转动连接一块挤压块，每块挤压块上转动连接一根下传力杆，套筒套在锚杆上且位于上传力杆下方，每根下传力杆另一端与套筒下方转动连接；螺杆通过与锚杆之间的匹配螺纹安装在锚杆上，碟形弹簧套在螺杆和锚杆上。本发明桥梁多向复位装置，使得主梁与桥墩之间任意一个方向发生相对位移均有限位、复位作用；结构简单不易损坏；地震下，锚杆可以防止落梁，并且锚杆以外构件可更换；有杠杆效应；对桥梁整体受力影响小。
