Finger joint is a bridge connection that has open characteristics, so that in its application a good drainage system is needed. This component is designed with a shape resembling two combs that are tied together.
The use of finger expansion joints is common in Indonesia, especially for the construction of bridges and flyovers. Plays an important role in accommodating the movements generated by concrete shrinkage and creep, shortening posttensioning, thermal variations, dead and live loads, wind and seismic loads and structural settlements.
Especially for this finger type bridge expansion joint, we present it in several types, including:
Finger joints are also called multi-gap because they have many gaps. It can be described that this type of connection has a shape like the fingers on both hands that are fused together so that it is called a finger joint.
Multi gap joints can accommodate movements from 75 mm. Because it is an open expansion joint, a good drainage system is needed at the bottom of the joint to damage the concrete layer underneath.
