Expansion joint system
First Claim
1. A cover plate expansion joint system for bridging a gap between spaced apart first and second structural members comprising:
- an elongated plate extending across said gap between said first and second structural members;
at least one pre-loaded load absorbing damper positioned between said elongated plate and said second structural member, wherein said load absorbing damper produces forces tending to separate said elongated plate and said second structural member;
at least one anchor for anchoring said elongated plate to said first structural member; and
at least one pre-loaded damped spring engaged with said at least one anchor and said elongated plate, wherein said at least one damped spring anchor produces forces tending to promote proximity between said elongated plate arid said first structural member.

Abstract
A cover plate system for a gap (15) between two structural members (10, 20) is provided. The system includes an elongated cover (30) that extends across the gap (15) from a first structural member (10) to a second, spaced-apart structural member (20). The cover plate system further includes damped spring anchors (40) for engaging the cover plate (30) to an underlying structural member (10) and dampers (50, 60) for absorbing energy imparted to the cover plate (30) by vehicular traffic. The cover plate system minimizes the strain energy that is absorbed by the cover plate (30), which results in less cover plate slapping and bouncing during operation.
