expansion joint
An Expansion Joint is a connection designed to absorb movement caused by the expansion and contraction of materials in a building or infrastructure structure, such as bridges, railways, and pipelines. This joint allows parts of the structure to move without causing damage, especially due to changes in temperature, load, or vibrations.
Various types of Expansion Joints are described below
