ABSTRACT:
An expansion joint cover installation includes first and second building members defining an expansion gap between them and a cover member spanning and covering the gap and engaging the building members. The cover member is held centered in the gap by a resilient centering system that is coupled between the building members and the cover member and includes a plurality of first tensioned flexible segments connected obliquely between the first building member and the cover member and a plurality of second tensioned flexible segments connected obliquely between the second building member and the cover member. By arranging the tensioned segments obliquely to the axis of the gap, they are relatively long and are able to provide an adequate centering force over a relatively large range of motion between open and closed states of the gap. Advantageously, the system includes two first tensioned flexible segments and two second tensioned flexible segments extending mutually divergently from a common cover connection point at substantially the lateral center of the cover member at substantially equal angles with the longitudinal axis of the cover member and maintained under substantially equal tension with the cover member centered in the gap.
