Buffering energy dissipation structure and inhaul cable anti-beam-falling device
The invention provides a buffering energy dissipation structure and an inhaul cable anti-beam-falling device, belongs to the field of bridge engineering, and aims to avoid beam-falling damage of a bridge under the action of an earthquake. The buffering energy dissipation structure is composed of a compression device, a first limiting plate, a first elastic buffering element, a second elastic buffering element, a second limiting plate and a supporting bottom plate. When high-destructive impact such as earthquake occurs, the first elastic buffering element impacts the second elastic buffering element under the action of cable force of the inhaul cable, and sliding friction occurs between the first elastic buffering element and the second elastic buffering element to consume energy and external impact energy. And meanwhile, in the extrusion process of the inner ring layer and the outer ring layer, the buffer layer in the second elastic buffer element elastically deforms to provide a buffer effect for the structure. The inhaul cable anti-beam-falling device adopting the buffering energy dissipation structure has the advantages of being high in buffering capacity, reliable in performance and the like, can be designed according to different earthquake fortification requirements, is simple in structure and can powerfully guarantee the safety of a bridge structure.
本发明提出了一种缓冲耗能结构及拉索防落梁装置，属于桥梁工程领域，以避免桥梁在地震作用下发生落梁破坏。所述缓冲耗能结构由压缩装置、第一限位板、第一弹性缓冲元件、第二弹性缓冲元件、第二限位板、支撑底板组成。当遇到地震等破坏性较强的冲击时，在拉索索力作用下，第一弹性缓冲元件撞击第二弹性缓冲元件，两者发生滑动摩擦耗能，消耗外部冲击能量。与此同时，第二弹性缓冲元件内的缓冲层在内、外圈层挤压过程中，发生弹性变形为结构提供缓冲作用。采用此缓冲耗能结构的拉索防落梁装置具有缓冲能力强、性能可靠等优点，可根据不同的抗震设防需要进行设计，结构简单，可有力保障桥梁结构的安全。
