Oil pressure type shock absorption and isolation support and using method thereof

Abstract

The invention discloses an oil pressure type shock absorption and isolation support and a using method thereof. An upper plate trough is formed above a lower plate trough, grooves are formed in the lower portion of the upper plate trough and the upper portion of the lower plate trough, and embedded steel bars are arranged at the upper portion of the upper plate trough and the lower portion of thelower plate trough; a steel pad body is cuboid and is arranged on the upper surface of a damping layer, the damping layer is arranged in the groove in the upper portion of the lower plate trough, andthe upper portion of the steel pad body extends into the groove in the upper plate trough and makes contact with the bottom face of the groove; And baffles are arranged on the side faces of the steelpad body in the groove of the upper plate trough, an oil hydraulic cylinder used for shock absorption is arranged between each baffle and the inner wall of the groove of the upper plate trough, each baffle is connected with the upper plate trough through a position adjusting mechanism, and the position adjusting mechanisms can enable the baffles to make contact with the side faces of the steel padbody or enable preset distances to be reserved between the baffles and the side faces of the steel pad body. The hysteretic characteristic of the support can be controlled, the natural vibration period of the structure is prolonged, and the anti-seismic property of the structure is improved; and the support can be used as a fixed, one-way or two-way support.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to an oil pressure shock-absorbing and isolating support and a using method thereof. Background technique [0002] Bridge bearings are important structural components connecting the bridge superstructure and substructure. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the bridge superstructure to the bridge substructure, so that the actual stress of the structure is consistent with the calculated theoretical diagram. According to the possibility of its displacement, it is divided into fixed support and movable support: ①The fixed support transmits vertical force and horizontal force, allowing the upper structure to rotate freely at the support but cannot move horizontally; ②The movable support only Transmits vertical forces, allowing the superstructure to rotate freely and move horizontally at the supports. The movable support can...

Problems solved by technology

[0004] In the prior art, for a certain bridge, the form of the bridge support has been determined once it is installed, and it is difficult to replace or change the direction of movement. At the same time, the hysteretic characteristics of the shock-absorbing and isolating support cannot be adjusted, and the structure cannot be improved as required. seismic performance
