Product Description

Product Description

What is an expansion joint?

 

As a moving 'living' structure, a bridge is continuously affected by vehicle load, wind conditions and temperature, which in turn contribute to its life span. Expansion joints are a vital component of any reinforced concrete, pre-stressed concrete and steel structures, and bridge decks in particular, as they absorb these movements, while also accommodating shrinkage, creep effects and changes in temperature experienced by the structure. An expansion joint is the element under the most strain in any engineering structure.

 

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.
