Highway bridge anti-falling beam limiting device
The invention discloses a highway bridge anti-falling beam limiting device, and relates to the technical field of bridges, the highway bridge anti-falling beam limiting device comprises a plurality of anti-falling beam buffer chains fixedly arranged between a pier and a bridge body, two groups of mounting blocks arranged side by side are detachably mounted on the top surface of the pier, and the plurality of mounting blocks in the same group are distributed in a linear array; two first mounting cavities and two second mounting cavities are formed in the mounting block, a first inserting hole vertically penetrating through the first mounting cavities and a second inserting hole vertically penetrating through the second mounting cavities are formed in the mounting block, a first threaded rod is arranged in the first inserting hole in a penetrating mode, and a second threaded rod is arranged in the second inserting hole in a penetrating mode. When the bridge body moves outwards, the first threaded rod and the second threaded rod are controlled to rise, the supporting rods are jacked up, the bridge body is made to be in an inclined shape, the bridge body further generates obliquely-downward force under the action of gravity, resetting of the bridge body under the action of rolling vibration of vehicles and strong wind is facilitated, and the risk of beam falling of the bridge body is reduced.
本发明公开了一种公路桥梁防落梁限位装置，涉及桥梁技术领域，包括固定设置于桥墩与桥体之间的多个防落梁缓冲链，在所述桥墩顶面可拆卸安装有两组并排设置的安装块，同一组的多个安装块线性阵列分布，所述安装块内开设有两个第一安装腔和两个第二安装腔，所述安装块上开设有竖直贯穿第一安装腔的插孔一和竖直贯穿第二安装腔的插孔二，所述插孔一内穿设有螺纹杆一，所述插孔二内穿设有螺纹杆二。本发明在桥体向外位移时，控制螺纹杆一和螺纹杆二上升，将支撑杆顶高，使桥体呈倾斜状，使桥体在重力作用下，还产生斜向下的力，有利于桥体在车辆碾压震动和强风作用下复位，降低桥体发生落梁的风险。
