Bridge anti-falling device suitable for high-cold and high-intensity area
The invention belongs to the technical field of bridge safety, and particularly relates to an anti-beam-falling device suitable for a bridge in an alpine and high-intensity district, the anti-beam-falling device comprises a concave connecting device, a convex connecting device, a high-strength spring, an anchoring device, a reserved anchoring hole and an anti-freezing coating, constraint can be established between a beam body and a base body, and therefore the purpose of preventing beam falling damage is achieved; the high-strength spring can be made of a high-ductility elastoplastic material and can effectively dissipate part of energy of an earthquake or an impact load when the earthquake occurs; the surface is coated with the anti-freezing coating, so that the anti-freezing performance can be improved, and the anti-freezing coating can better meet the requirement of long-term work in alpine regions without being damaged by low temperature; according to the utility model, the bridge body and the base body are tightly connected together through the anchoring device and the reserved anchoring holes, the displacement of the bridge body and the base body is limited in the vertical upward direction, and when the bridge jumps in the vertical direction due to hurricanes or earthquakes and the structure of the bridge, the anti-pulling effect is achieved.
本发明属于桥梁安全技术领域，具体为一种适用于高寒、高烈度区桥梁防落梁装置，包括凹形连接装置、凸形连接装置、高强弹簧、锚固装置、预留锚固孔、防冻涂层，该发明可以在梁体与基体间建立约束，从而实现防止落梁破坏的目的；高强弹簧可选用高延性的弹塑性材料制成，在发生地震时能够有效的耗散部分地震或冲击荷载的能量；表面涂抹防冻涂层可提高其防冻性能使其更好的满足在高寒地区长期工作而不被低温破坏；通过锚固装置和预留锚固孔与梁体和基体紧密连接在一起，在竖直向上方向限制梁体与基体的位移，当桥梁因为飓风或地震及本身的结构原因在竖直方向发生跳动时，具有抗拔拉作用。
