Bridge-rubber-pad limiting energy dissipation device

Abstract

The invention discloses a bridge-rubber-pad limiting energy dissipation device. The bridge-rubber-pad limiting energy dissipation device is arranged between a bridge surface and a bridge pier; two rubber pads are symmetrically arranged on the bridge in the transverse direction of a bridge left and right, transverse pipes penetrate through the rubber pads along the centers of the side walls of therubber pads, protection caps are arranged in the centers of the side walls of the rubber pads, each protection pad is connected with a connection steel pipe, one ends of the two connection steel pipesare arranged in the transverse pipes, the other end of one connection steel pipe is connected with the bridge surface, the other end of the other connection steel pipe is connected with the bridge pier, the two connection steel pipes are arranged at pipe openings in the transverse pipes, and are each provided with a connection ball, and the two connection balls are each connected with an energy dissipation spring, and are connected through the energy dissipation springs. By means of the bridge-rubber-pad limiting energy dissipation device, rigidity damage between the bridge surface and the bridge pier can be avoided, and the falling phenomenon of the bridge surface is prevented.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a position-limiting energy-consuming device for bridge rubber pads. Background technique [0002] With the development of the economy, my country's construction industry has also achieved unprecedented development, especially in terms of transportation. my country has a vast territory, and the construction of roads and bridges is the top priority. [0003] At present, the seismic design of bridges in our country mainly emphasizes the strength of the pier, and how to prevent the pier from collapsing in an earthquake. The anti-fall beam structure adopted is mainly to fix the anti-fall beam stoppers on the pier to control the longitudinal displacement and lateral displacement of the beam within a certain range. However, due to the lack of connection between the beam body and the pier body, and between the beam body and the beam body, when a high-intensity ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a bridge rubber pad position limiting energy dissipation device. Since the device is equipped with a rubber pad, the longitudinal wave energy is transmitted to the bridge pier when an earthquake arrives, and the pier transmits the energy to the rubber pad. The deformation of the pad consumes energy, the shear wave energy transmits the bridge pier and the bridge deck, the bridge pier and the bridge deck produce relative displacement, the connecting steel pipes in the rubber pad produce mutual tension, the connecting ball and the ring steel sheet produce extrusion, and the energy-dissipating spring produces deformation and consumes energy. Avoid rigid damage to the bridge deck and piers, and prevent the bridge deck from falling off
