Bridge expansion joint connection member with flexible seal

Abstract

The invention relates to the technical field of bridge expansion joints, and discloses a bridge expansion joint connection member with a flexible sealing part, including rods, and the number of the rods is two, and the two rods are symmetrically distributed, and the two rods are symmetrically distributed. The bottoms of the two rods are fixedly connected with strip plates, and the opposite sides of the two rods are provided with a first groove and a second groove, and the second groove is located at the bottom of the first groove. The bridge expansion joint connecting member with a flexible sealing part is provided with a plurality of first connecting mechanisms and two first springs on the first connecting mechanisms, which is conducive to adapting to changes in the lateral positions of the two rods while providing Good cushioning performance, by providing the second spring, it is beneficial to adapt to the vertical position change of the two rods while providing good buffering performance, compared with the prior art, it can make the connection between the two rods more stable, and at the same time Provides good cushioning and deformation resistance.

Description

technical field [0001] The invention relates to the technical field of bridge expansion joints, in particular to a bridge expansion joint connection component with a flexible sealing part. Background technique [0002] Bridge expansion joints refer to expansion joints usually set between two girder ends, between girder ends and abutments, or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. It is required that the expansion joints can freely expand and contract in two directions parallel to and perpendicular to the bridge axis, and are firm and reliable. The vehicles should run smoothly without sudden jumps and noises; they should be able to prevent rainwater and garbage from infiltrating and blocking; installation, inspection, and maintenance 1. The removal of dirt should be simple and convenient. The structure of the expansion joint includes two symmetrically distributed rods. The common cross-section is C-shaped or F-sh...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a bridge expansion joint connection member with a flexible sealing part, which uses its own protective structure and unique laying method to realize automatic dynamic sewage cleaning, has good seismic performance, and is not easy to accumulate sand and soil. It solves the problem that the connecting members between the common expansion joints have simple structure, poor shock absorption performance and deformation resistance, and at the same time, the flexible sealing rubber in the expansion joint is easy to accumulate sand and soil, which hinders the change of the expansion joint and has a negative impact on the safety of the bridge. question
