One-way energy consumption collapse-proof device

Abstract

The invention discloses a one-way energy consumption collapse-proof device, which includes a bottom plate. At least one corrugated plate is mounted on the bottom plate; sections of all corrugated plates are in wavy configuration with the same extending direction of the corrugated plates, and blocking plates are correspondingly arranged at the two sides of wave peaks and wave troughs of the corrugated plates; all blocking plates are connected with the bottom plate, and two ends of the corrugated plates are connected with the bottom plate which is used for connecting with piers; limiting groovesare formed in the plate body of the corrugated plates, sliding blocks are arranged in the limiting grooves, and the limiting direction of the limiting grooves and the extending direction of the corrugated plates are the same; and in an original state, intervals are formed in two sides of the sliding blocks, which is used for connecting with a beam body, and the limiting grooves. According to theone-way energy consumption collapse-proof device, an energy consumption member and a collapse-proof device are combined effectively, so the collapse-proof device has the prominent capacity of reducingshock and energy consumption; and at the stage of normal operation, double-way movement of the beam body is satisfied, the participation of the energy consumption member is reduced, and energy consumption is efficient and proof collapsing is avoided when the earthquake is coming.

Description

technical field [0001] The invention relates to the technical field of anti-falling beam energy consumption of railway bridges, in particular to a one-way energy-consuming anti-falling beam device. Background technique [0002] The anti-falling beam device is the key structure of bridge anti-seismic. It is mainly used to prevent the falling beam caused by the excessive relative displacement between the upper structure and the lower structure. Therefore, the anti-falling beam device is generally used in bridge engineering in earthquake areas. [0003] In the prior art, the anti-fall beam devices of highway bridges in my country generally adopt concrete stoppers, high-strength steel tie rods, high-strength steel cables, etc., while the anti-fall beam devices of railway bridges generally adopt various types based on I-beam processing. However, the anti-fall beam devices of the above-mentioned forms generally have certain limitations, which are specifically reflected in the follo...
