Abstract

The invention discloses a bridge expansion device. The bridge expansion device comprises a first edge beam, a second edge beam, a connecting block and a cover plate, a middle beam assembly is arrangedbetween the first edge beam and the second edge beam, the middle beam assembly comprises a plurality of middle beams which are sequentially arranged between the first edge beam and the second edge beam in parallel, and sealing strips are arranged between the edge beams and the adjacent middle beams and between every two adjacent middle beams. The connecting block abuts against the side, away fromthe second edge beam, of the first edge beam. The cover plate abuts against the side, away from the second edge beam, of the first edge beam, the connecting block is located on the lower side of thecover plate, and the connecting block is connected with the cover plate through the shear connector. The supporting beam is used for supporting the middle beam. When an earthquake occurs, excessive parts can be prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of bridge structures, and in particular relates to a bridge telescopic device. Background technique [0002] Bridge telescopic device refers to that in order to meet the requirements of bridge deck deformation, telescopic devices are usually installed between two girder ends, between the girder end and abutment, or at the hinged position of the bridge. The patent No. ZL 200820039362.1 discloses a modular bridge expansion device. It can be seen from the figure that the side beams are welded to the displacement control box, and the middle beam is welded to the support beam. When an earthquake occurs, the deformation of the bridge expansion device The amount will be very large, and the device will be connected by welding and other methods, which will cause damage to the side beams, center beams, displacement control boxes and support beams, which is not conducive to repeated use, and the extrusion of parts will...
