An expansion joint for floor panels such as concrete slabs, as well as wall and ceiling panels, has a thickness equal to a covering material on the panels and is surface mounted. An expansion joint member which can be an integral extruded or otherwise formed length bridges across substantially abutting panels at a variable gap, the panels having coplanar surfaces on at least one side and a covering material thereon. The joint member has a U-shaped body portion having a width greater than a maximum width of the gap, and fasteners adjacent one side of the gap for affixing the body portion to one of said panels defining an attachment side of the joint. The body portion bridges across the gap and rests freely on the coplanar surface of the panel on an opposite side of the gap. Wing members are attached to the body portion on the attachment side and on the opposite side, in each case at a space from the lower surface of the body portion equal to a thickness of the covering material on said attachment side.
