Bridge damping structure

Abstract

The invention belongs to the technical field of bridge shock absorption, and discloses a bridge damping structure which comprises an upper supporting plate and a lower supporting seat, and a longitudinal shock absorption assembly and a transverse shock absorption assembly are arranged between the upper supporting plate and the lower supporting seat. The longitudinal damping assembly comprises an upper pressing block and a lower supporting spring, the upper pressing block is fixed to the bottom of the upper supporting plate, the lower supporting spring is fixed into the lower supporting seat, and the upper pressing block stretches into the lower supporting seat and is pressed on the top of the lower supporting spring. The transverse damping assembly comprises a mounting frame slidably arranged in the lower supporting seat and a supporting sleeve welded to the outer portion of the mounting frame in a sleeving mode, an arc-shaped groove is formed in the top of the supporting sleeve, and an arc-shaped plate is supported at the top of the supporting sleeve in a matched mode through the arc-shaped groove. By means of the damping structure, on one hand, a bridge is supported, and on the other hand, multi-directional shock absorption of the bridge in the using and earthquake process is achieved based on the longitudinal damping assembly and the transverse damping assembly which are matched with each other.

Description

technical field [0001] The invention belongs to the technical field of bridge damping, and in particular relates to a bridge damping structure. Background technique [0002] At present, during the use of the bridge or under the action of earthquakes, relative displacements will occur in different directions. When the displacement exceeds the actual length or limit of the bridge to prevent beams from falling, beams will fall, resulting in traffic interruption. [0003] In the prior art, in order to solve the above problems, bridge damping structures are mostly used to damp bridges; traditional bridge damping structures are usually bridge damping pads, but the damping effect of bridge damping pads is not good. In the event of an earthquake or severe vibration of the bridge support seat, the shock wave cannot be dispersed well and the bridge will be damaged. [0004] For this reason, a novel bridge shock-absorbing structure with good shock-absorbing effect is designed in this ...
