Abstract

An expansion joint cover (10) broadly comprises a cover plate (38) to cover an expansion joint (12) between a first and second surface (14,16), an anchor assembly (40) to secure the plate (38) to the first surface (14), an insert (46) to protect the second surface (16), and one or more resilient bushings (48) to isolate the plate (38) from the anchor assembly (40). Under adverse conditions, such as during seismic events, the surfaces (14,16) may move significantly with respect to one another, thereby causing the plate (38) to slide over the second surface (16) and the insert (46) and deform the bushings (48). Thus, the flexibility of the plate (38), the durability of the insert (46), and the resilience of the bushings (48) all cooperate to allow the cover (10) to minimize stresses otherwise transferred to the anchor assembly (40).
