Problems solved by technology

[0002] When designing bridges, the impact of earthquakes or other vibrations on bridges is taken into account. Generally, various types of shock absorbers are installed between bridges and piers to reduce the damage caused by earthquakes to bridges. Usually shock absorbers are installed On both sides of the pier, the shock-absorbing effect is completely determined by the performance of the shock-absorbing dampers and the number of shock-absorbing dampers. When applied, the shock-absorbing dampers on both sides of the pier work independently without interfering with each other. There is one of the shock-absorbing dampers The damper works frequently, and the other shock absorber basically does not work, which leads to the low service life of one of the shock absorber dampers and frequent replacement, which increases the maintenance cost of the bridge

Abstract

The invention discloses a transverse energy dissipation damping device suitable for bridge structures and an installation method thereof, and mainly relates to the technical field of bridge damping. It includes a pipe body that runs through the pier horizontally, a central rod is arranged in the pipe body, connecting rods are hinged at both ends of the central rod, and a shock-absorbing damper is provided at the end of the connecting rod far away from the central rod. The shock damper is fixed on the bottom surface of the bridge, two first springs are sleeved on the central rod, and first baffles compatible with the first springs are provided at both ends of the central rod. Two ends of each are provided with a second baffle plate adapted to the first spring, and the first spring is located between the first baffle plate and the second baffle plate. The beneficial effect of the present invention is that it can utilize two shock absorbing dampers at the same time, avoid frequent work of one of the shock absorbing dampers, can share the load equally between the two shock absorbing dampers, and reduce the replacement frequency of the shock absorbing dampers , to reduce bridge maintenance costs.
