Anti-seismic stop block device of bridge and bridge
The invention relates to the technical field of bridge engineering, and provides an anti-seismic stop block device of a bridge and the bridge. The anti-seismic stop block device comprises a supporting piece, a collision piece and a damping structure; the head-on collision piece is used for bearing the collision force of the main beam; the damping structure comprises at least two force transmission pieces which are arranged in an arrayed mode. The two ends of the force transmission piece are connected with the supporting piece and the head-on collision piece respectively. According to the anti-seismic stop block device of the bridge and the bridge, when an earthquake occurs, earthquake excitation is transmitted to the next force transmission piece from one force transmission piece, and all the force transmission pieces yield step by step in sequence to dissipate input energy of the earthquake; when the earthquake response is gradually enhanced, the main beam of the bridge collides with the collision piece, each force transmission piece gradually yields, and the peak response under the earthquake condition can be effectively reduced. And when the force transmission piece reaches the maximum deformation, the supporting piece accumulatively deforms to reach the final yield, earthquake energy is continuously consumed, multi-stage fortification and multi-stage energy consumption are achieved, and earthquake force is effectively reduced.
本发明涉及桥梁工程的技术领域，提供一种桥梁的抗震挡块装置及桥梁，包括支撑件、迎撞件和减震结构，支撑件安装于桥梁上；迎撞件用以承载主梁的撞击力；减震结构包括至少两个传力件，各传力件排列设置；所述传力件的两端分别连接所述支撑件和所述迎撞件。本发明所述的一种桥梁的抗震挡块装置及桥梁，地震发生时，地震激励从一个传力件传递到下一个传力件，各个传力件依次逐级屈服，耗散地震的输入能量；当地震响应逐渐增强时，桥梁的主梁撞击到迎撞件，各个传力件渐次屈服，可有效降低地震状况下的峰值响应。当传力件达到最大变形时，支撑件累积变形达到最终屈服，继续消耗地震能量，实现多级设防、多级耗能，有效降低地震力。
