Product Description
Product Description
Finger expansion joints are designed to handle movements of 80 mm to 1,200 mm are composed by steel finger plates, CR sheet, anchor bolts and other components. The rubber sheet is placed on the retractable steel, and anchor bolts help to fix the whole structure. The orientation of the fingers is in the direction of vehicle travel, which can reduce noise and improve driver's comfort. There is a drainage channel which allows rainwater to enter the bridge's drainage system, hanging beneath the joint.
Features
Application
Finger expansion joints are suitable for both new bridges and existing bridges. They are also good choices for the large-span bridges and do well in replacing the old ones. Finger expansion joints are widely used among steel box girders, among concrete beams, and between steel box girders and concrete beams. Finger expansion joints also can be used in expressway.
