Accommodating Bridge Deformation: Bridges deform during use due to factors such as temperature fluctuations, vehicle loads, concrete shrinkage, and creep.
Ensuring Driving Comfort and Safety: Bridge expansion joint steel helps maintain the smoothness of the bridge deck. Without expansion joint steel or a faulty expansion joint mechanism, the bridge deck may experience height differences and misalignment at the expansion and contraction locations.
Protecting the Bridge’s Main Structure: As a key component of the bridge’s expansion and contraction mechanism, expansion joint steel prevents rainwater and debris from entering the bridge’s main structure. Without effective protection from expansion joint steel, rainwater can penetrate into structural components such as beams and piers, leading to durability issues such as steel reinforcement and concrete corrosion.
Material materials commonly used include Q355B and Q390B, and standard lengths range from 6 to 12 meters.
