The invention discloses an anti-seismic safety bridge, and belongs to the technical field of bridges, the anti-seismic safety bridge adopts a cover beam with a concave arc-shaped surface at the top, two rows of padstones and supports are arranged on the arc-shaped surface, and the bottom of a beam body is clamped on the arc-shaped rows of supports by arranging arc-shaped blocks, so that on one hand, dimensional support is realized, and on the other hand, the anti-seismic safety bridge is supported; on the other hand, the situations that the support is damaged and the beam body falls off due to large-amplitude vibration during an earthquake are avoided; meanwhile, the two ends of the cover beam are symmetrically provided with the frame-shaped damping and limiting seats in the shape of a Chinese character'ji ', damping and limiting in the axial direction and the vertical direction of the beam body are achieved, the stability of the beam body when the beam body deals with vibration and earthquakes is improved, and the adjustable elastic supporting seat is installed between the frame-shaped damping and limiting seats on the two sides and used for relieving and counteracting vertical vibration; and the adjustable limiting pieces are mounted on the cover beam, so that the adjacent ends of the beam bodies on the two sides are elastically limited in the lateral direction and the vertical direction, the vertical amplitude of the beam bodies is buffered and limited, the beam bodies are prevented from falling off, and the vertical anti-seismic protection performance is further improved.
本发明公开了一种抗震式安全桥梁，属于桥梁技术领域，本发明采用顶部具有内凹的弧形面的盖梁，同时弧形面上设有两排垫石、支座，梁体底部通过设有弧形块卡装在弧形成排的支座上，一方面实现维度支撑，另一方面避免地震时大幅震动所带来的支座损坏，梁体落梁的情况发生；同时在盖梁两端对称安装有呈日子型的框型减震限位座，实现对梁体轴向与竖向的减震和限位，增加了梁体应对震动和地震时的稳定性，两侧的框型减震限位座间安装有可调节弹性支撑座，用于缓解和抵消竖向的震动；又通过在盖梁上安装有可调节限位件，对两侧梁体相邻端进行侧向与竖向的弹性限位，用于对梁体竖向的振幅进行缓冲限位，防止梁体脱落，进一步增加了竖向的抗震防护性能。
