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.

    Finger expansion joint consists of interlocking steel finger plates that accommodate large bridge movements through relative sliding between plates. Suitable for movement ranges of 160-1000mm in long-span bridges. The product offers excellent drainage and high load-bearing capacity, commonly used in cable-stayed bridges and suspension bridges.

Material
Finger plates: Q355B or Q420B hot-rolled steel, plate thickness 20-60mm. Sliding plate: Modified PTFE with compressive strength ≥30MPa. Waterproof strip: EPDM rubber with tensile strength ≥12MPa. Anchorage system: HRB400 threaded steel. Stainless steel plate: 06Cr19Ni10 mirror polished.
