Combined bridge supporting device with damping and toppling prevention functions

Abstract

The invention discloses a combined bridge supporting device with damping and toppling prevention functions, which comprises two supports, a plurality of bridge damping seats, a bridge girder, a connecting beam, a front swing arm, a rear swing arm and two damping devices, the two supports are respectively arranged at the front end and the rear end of a cover beam, and the front support is provided with the front swing arm. A rear swing arm is arranged on the rear support, the two ends of the connecting beam are connected with the free end of the front swing arm and the free end of the rear swing arm respectively, the connecting beam is connected with a bridge girder, the front swing arm is further connected with the front support through a damping device, and the rear swing arm is further connected with the rear support through a damping device. A bridge shock-absorbing seat is arranged between the lower ends of the cover beam and the bridge girder, the bridge shock-absorbing seat comprises a base, a sleeve body, a sliding support and two shock-absorbing devices, and compared with the prior art, the bridge shock-absorbing seat has the advantages that the shock-absorbing effect can be improved, the service life can be prolonged, and the occurrence of transverse beam falling accidents can be reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of bridge engineering, in particular to the technical field of a combined bridge support device with shock absorption and anti-dumping. 【Background technique】 [0002] With the development of the transportation industry and the improvement of construction engineering standards, bridge damping bearings not only play a supporting role in bridges and other projects, but also have a shock-absorbing effect. Specifically, a buffer and anti-seismic device is installed between the bridge body and the bridge support to reduce the vibration generated by the vehicles on the bridge and provide protection for the bridge as a whole. The existing anti-seismic device has poor anti-seismic ability and short service life. [0003] Under excessive earthquake action, the main girder of the bridge structure tends to produce large lateral displacement upwards of the cross bridge, and the main girder will directly contact the l...

AI Technical Summary

Problems solved by technology

In the prior art, when the main girder undergoes lateral displacement and hits a certain side of the anti-seismic block, the impact force cannot be shared by the anti-seismic blocks on both sides, so the impact force borne by the anti-seismic block on one side increases greatly, and it is easy to Causing the occurrence of lateral falling beam accidents
