Abstract

The invention discloses a multi-level anti-seismic device capable of preventing a bridge from colliding and falling. The device is characterized by comprising a left-end limiting assembly connected with a left beam, a right-end limiting assembly capable of being connected with a right beam, a connecting assembly and an energy dissipation assembly fixed with a bridge pier, wherein the left-end limiting assembly and the right-end limiting assembly are overlapped and can limit sliding structures leftwards and rightwards, the connecting assembly is located between the left-end limiting assembly and the right-end limiting assembly and can transmit seismic force produced when a left beam and a right beam are separated by the left-end limiting assembly and the right-end limiting assembly to the energy dissipation assembly, energy is dissipated by the energy dissipation assembly through elasticoplastic deformation, the device can realize multi-level limiting functions including free deformation during small displacement, energy consumption during medium displacement and locking during large displacement. With the adoption of the structure, the device capable of preventing the bridge from colliding and falling is simple and reliable in structure and can effectively control the bridge from falling or colliding during earthquake, and the safety of the bridge is guaranteed.

Description

technical field [0001] The invention relates to the technical field of shock absorption and isolation of bridges. Background technique [0002] Earthquake is one of the most destructive natural disasters in history. Bridge engineering is a lifeline project. If there is no reasonable anti-seismic design, the earthquake will cause serious losses to people's lives and property. The cost of the existing anti-falling beams and shock-absorbing energy-consuming devices is high, the structure is complex, and it is difficult to popularize and use them. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-stage anti-seismic bridge anti-collision and beam drop device for the above-mentioned deficiencies in the prior art. Collision, to ensure the safety of the bridge. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] An anti...
