Anti-collision connecting device for bridge

Abstract

The invention discloses an anti-collision connecting device for a bridge, and relates to the technical field of bridge protection, the anti-collision connecting device comprises two bridge bodies, piers are arranged below the bridge bodies, supports are arranged between the piers and the bridge bodies, an expansion joint is arranged between the two bridge bodies, and a middle cover is arranged inthe expansion joint; the bottom of the bridge body is slidably connected with a sliding seat, the bottom end of the sliding seat is fixedly connected with a moving column, and the moving column is connected with a buffering device. The bridge can move and buffer horizontally and transversely through the arrangement of the middle cover and the buffering device, and meanwhile translation buffering of the bridge in the horizontal and longitudinal directions can be achieved; the anti-collision connecting device is simple in structure and convenient to use, has multi-directional buffering and anti-collision capacity, is good in bridge protection, can detect the instantaneous movement power of a bridge by arranging the detection device, can monitor the movement condition of the bridge, and has agood auxiliary effect on bridge protection.

Description

technical field [0001] The invention relates to the technical field of bridge protection, in particular to an anti-collision connection device for bridges. Background technique [0002] The damage of the bridge under the earthquake load is mainly caused by the damage of the pins of the support, which makes the superstructure of the bridge deviate. When the offset is large, beam fall will occur. Beam drop is a serious earthquake damage to bridges, which is difficult to repair in a short period of time. It will inevitably affect the disaster relief work after the earthquake and cause large economic losses. Arranging anti-collision and anti-drop beam devices between the left and right bridges plays a very important role in improving the seismic capacity of the bridge and reducing the seismic damage of the bridge to the greatest extent. [0003] In the Chinese invention patent document with the notification number CN104612042B, an anti-collision connection device for bridges is...

[0003] In the Chinese invention patent document with the notification number CN104612042B, an anti-collision connection device for bridges is announced. Under the action of temperature load, the speed of the piston rod pushing the piston is relatively slow, which can realize free expansion and contraction deformation without affecting the left and right sides. The release of the temperature stress of the beam body; under the action of earthquake load, the movement speed between the left and right beam bodies is faster, and because the pores o
