Bridge expansion joint: refers to the expansion joint between two beam ends, between beam ends and abutment, or on the hinge position of the bridge to meet the requirements of bridge deck deformation. In parallel and perpendicular to the bridge axis, firm and reliable, the vehicle should be smooth and outdated without jump and noise; and it can prevent rainwater and garbage soil from infiltration and blocking; the installation, inspection, maintenance and dirt elimination should be simple and convenient. At the expansion joint, the railing and the bridge deck pavement should be disconnected.

The selection of the appropriate expansion joint type depends on factors such as the bridge's size, expected movement, load requirements, and the local climate and environmental conditions.

Features of bridge expansion joints include:

Modularity and Adjustability:

Many expansion joint designs are modular, allowing for easy installation, repair, and replacement of individual components as needed.

Some joints may also incorporate adjustable features to accommodate changes in the bridge structure or to fine-tune the joint's performance over time.

Maintainability:

Expansion joints are designed with accessibility and ease of maintenance in mind, facilitating regular inspections, cleaning, and replacement of worn or damaged components.

This ensures the continued functionality and safety of the bridge expansion joint system.

 

Classification of Bridge expansion joints : butted type, steel support type, combined shear type (plate), modular support type and elastic device.
