Deevin finger joint consists of multi-directional displacement hinge, sliding finger plate, fixed finger plate, support bracket, anchorage, and drainage system. The multi-directional displacement hinge is the key component of the finger joint, with capacity to accommodate the bridge three-dimensional deformation demands.
The fixed finger and the sliding finger plate components are located at the two opposite sides of the expansion gap. As the bridge deck expands and contracts, the fingers of the sliding part slide longitudinally between the fingers of the fixed part.
