An anti-falling beam isolation device based on bridge girder shock absorption

Abstract

The invention belongs to the technical field of bridge protection, in particular to an anti-drop beam isolation device based on the shock absorption of bridge girders. The top of the support beam is provided with a mounting groove, and a support plate is slidably connected to the mounting groove, and the bottom of the support plate is fixed. The buffer assembly is installed, and the top of the support plate is fixedly installed with a fixed platform, the top of the fixed platform extends to the top of the support beam and is fixedly installed with a support ring, and the top of the fixed platform is provided with a connecting groove connected with the support ring. The top of the ring is fixedly equipped with a bridge plate, and the bottom of the bridge plate is fixedly installed with a support column, and the bottom end of the support column extends into the connecting groove. The present invention realizes the stability control of the bridge plate by installing the bridge plate on the support ring Position, to prevent the bridge plate from shifting, and to achieve good shock absorption on the bridge plate, so the bridge plate can be well protected during daily use, and the service life of the bridge can be extended.

Description

technical field [0001] The invention belongs to the technical field of bridge protection, and relates to an anti-falling beam isolation device based on the vibration reduction of bridge girder bodies. Background technique [0002] In recent years, with the rapid development of bridges and construction projects in our country, various construction projects with new structural forms and functions have emerged. my country has put forward a special mission for bridge projects. The 5.12 Wenchuan Earthquake caused huge losses. Wenchuan The nearby infrastructure has been severely damaged, especially the bridge damage. Among them, falling beam damage, collision between beam bodies, and block damage are the main forms of bridge damage that hinder traffic. [0003] At present, most of the bridge anti-fall beam devices used rely on the cooperation of the anti-collision block arranged on the cap platform and arranged in the direction of the horizontal bridge with the upward anti-fall bea...

AI Technical Summary

Problems solved by technology

[0004] In view of this, in order to solve the problem that the buffering and shock absorption performance of the beam body is often not ideal after the anti-collision stopper is installed on the beam body, the present invention provides an anti-falling beam isolation device based on the shock absorption of the bridge beam body
