ABSTRACT:
A covering for an expansion joint is formed of a plurality of monolithic steel elements that are arranged to be self-cleaning and so as not to be subject to binding. The joint has an overall T-shape and is bilaterally symmetric. The joint includes two L-shaped portions each attached to a structural element for movement therewith. The joint cover has a steel plate on one leg of each L-shaped portion bordering the expansion gap. A spacer plate is also fixed to the leg of the L-shaped portion and forms a sealant-receiving channel with the leg and the plate. An expansion gap spanner plate slidably rests on top of the plate and a cover plate is fixed at one end to the spacer plate and slidingly engages the spanner plate to keep it in the desired position and orientation during movement of the joint.
