Buffer energy-consuming anti-drop-beam device for bridge
The invention discloses a buffer energy-consuming anti-drop-beam device for a bridge, which can effectively resist to an earthquake disaster, prevent an adverse impact caused by over lateral displacement of the bridge and avoid the damage caused by the drop of a beam, and is convenient to mount and replace. The buffer energy-consuming anti-drop-beam device comprises an upper mounting plate which is fixedly mounted on a beam body, and a lower mounting plate which is fixedly mounted on a bridge pier. A guide groove structure is arranged at the lower end of the upper mounting plate; a transverse bridge direction guide groove of which the lower end is provided with an opening is formed in the guide groove structure. Energy consuming pieces which are made of soft steel and are provided with variable-width plate bodies are arranged between the upper mounting plate and the lower mounting plate in the transverse bridge direction at intervals; the upper parts of the energy consuming pieces are positioned in the transverse bridge direction guide groove and are restrained by the transverse bridge direction guide groove; the lower parts of the energy consuming pieces are fixedly connected with the lower mounting plate.
