Abstract

The invention discloses a vibration damping and buffering support for a highway bridge, the vibration damping and buffering support comprises a base, buffering bases are fixedly connected on the top of the base, the upper surface of the base is provided with a vibration damping support, the lower surface of the vibration damping support is provided with a groove matched with the buffering seat, the two sides of the inner wall of the top of the groove are respectively provided with a clamping groove, first damping springs are fixedly connected to the interiors of the clamping grooves, sliding plates are fixedly connected to the bottoms of the first damping springs, supporting rods movably connected with the buffering seats are arranged at the bottoms of the sliding plates, and buffering cavities are formed in the buffering bases. The vibration damping and buffering support for the highway bridge is novel in structure and ingenious in conception, can achieve the effect of multiple times of vibration damping and buffering on the highway bridge, further effectively improves the stability of the highway bridge, prevents the bridge from being damaged by external force, improves the safety of the bridge, prolongs the service life of the bridge, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a vibration-damping buffer support for highway bridges. Background technique [0002] Under the action of external vibration, the bridge will cause its own vibration, which will cause damage to the bridge structure. Over time, this damage will directly affect the safety and service life of the bridge. Engineering is crucial, and it is also an important indicator to measure the quality of bridge engineering. [0003] The existing vibration damping devices for highway bridges have a single structure, limited vibration damping and buffering effects, and cannot meet the needs of use. Therefore, it is necessary to design a vibration damping and buffering support for highway bridges. Contents of the invention [0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a vibration-damping buffer bearing for hig...
