Problems solved by technology

[0002] The bridge bearing is an important structural component connecting the superstructure and substructure of the bridge. It is located between the bridge and the pier. It can reliably transmit the load and deformation (displacement and angular rotation) borne by the superstructure of the bridge to the substructure of the bridge. The important force transmission device, the commonly used rubber plate support can carry enough load, but its shock absorption effect is not obvious

Abstract

The invention belongs to the technical field of bridges, and particularly relates to a bridge damping support base. The bridge damping support base includes a bridge body and a pier; damping structures are arranged between the lower surface of the bridge body and the upper surface of the pier; each damping structure includes a support base top plate, a damping spring, a support base bottom plate and a hydraulic cylinder, locating plates are fixedly welded to the lower surfaces of the support base bottom plates and the upper surfaces of the support base top plates, and the hydraulic cylinders are arranged between the support base bottom plates and the support base top plates; when the bridge body is stressed, the elastic force of compressed in-cylinder springs pushes pistons to move downwards, hydraulic oil is extruded from the first damping mechanism into the hydraulic cylinder of the second damping mechanism through a corresponding high-pressure tube so that the piston in the second damping mechanism can move upwards and compress the in-cylinder spring of the third damping mechanism; in this way, by making one damping spring stressed and making two in-cylinder springs stressed, and through hydraulic stress, multiple buffering is achieved to damp received loads.

Description

technical field [0001] The invention belongs to the technical field of bridges, and in particular relates to a bridge damping bearing. Background technique [0002] The bridge bearing is an important structural component connecting the superstructure and substructure of the bridge. It is located between the bridge and the pier. It can reliably transmit the load and deformation (displacement and angular rotation) borne by the superstructure of the bridge to the substructure of the bridge. As an important force transmission device, the commonly used rubber plate bearing can carry enough load, but its shock absorption effect is not obvious. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a bridge shock-absorbing support, which has different degrees of buffering and shock-absorbing effects on different sizes of pressure loads, and can adapt to the influence of concrete shrinkage and cre...
