Finger Type Expansion Joints
The finger type bridge expansion joint is usually made of steel edge profile with thick steel finger plates anchored with high quality bolts. It is very unlikely to wear and damage the system surface, which consists of interlocking finger plates. As a result, there is low maintenance cost. When using steel finger plates in the system, the damage that can occur in the expansion joint is very limited and the expansion joint has a long service life. The most important reason for this is the fact that there is very little impact between the vehicles through the expansion joint since the finger plates are continuous. Thus, the noise generated during the transition over the expansion joint is reduced and comfortable transition is provided. A rubber gasket is installed to provide impermeability to the bottom of the expansion joint. Since the used seals are resistant to water, salt and other chemicals, damages to the infrastructures and the top layer can be prevented by foreign substances that may come from the outside. inger bridge expansion joints can be applied to all types of bridges. Models with different movement capacities are manufactured according to the desired expansion value. The table shown below present the some of the model.
