Description: Site Logo Finger Joints Galvano Structures India Pvt. Ltd. > Production > Finger Joints DESCRIPTION Finger Type expansion joints used in bridge construction are an ideal component to accommodate bridge expansion and contraction while reducing the amount of noise pollution that occurs in other alternative joint types.The primary components of the Finger Type expansion joint consist of steel plates (sliding) that are connected to each side of the road surface’s gap. Finger Joints are designed with in a (fingers of a hand) type of pattern, where the steel plates accommodate movement within one another & allow movement along the axis of the fingers themselves. Since there are no moving parts attached to the joint, cantilever moments reduce the stress induced to the structure. There is a large replaceable gutter below the joint which is made of reinforced neoprene and provides an efficient drainage system into the bridge’s ducts. The gutter also limits the build-up of standing water to reduce the possibility of vehicles aquaplaning.
