Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
A composite expansion joint assembly comprising: edge members adapted to define the opposite sides of an expansion groove between deck sections; at least two resiliently yieldable elongated sealing elements in side-by-side relation; an elongated rigid structural member interposed between said sealing elements; support bars extending transversely of said rigid structural member and being connected thereto for supporting the same; means supporting said support bar adjacent the opposite ends thereof for sliding movement relative thereto adjacent at least one end thereof; and elastic, non-metallic, means for resiliently separating said rigid structural member from said support bars for limited movement relative thereto for absorbing noise, stress and strain therebetween and mounting means for connecting said support bar to said rigid structural member comprising, fastening means secured to a surface of said elongated rigid structural member and means fixidly secured to said support bar for receiving said fastening means wherein said rigid structural member is substantially anchored to said support bar.
Claim 2
Dependent Claim
158 words
A composite expansion joint assembly comprising: edge members adapted to define the opposite sides of an expansion groove between deck sections; at least two resiliently yieldable elongated sealing elements in side-by-side relation; an elongated rigid structural member interposed between said sealing elements; support bars extending transversely of said rigid structural member and being connected thereto for supporting the same; means supporting said support bar adjacent the opposite ends thereof for sliding movement relative thereto adjacent at least one end thereof; and elastic, non-metallic, means for resiliently separating said rigid structural member from said support bars for limited movement relative thereto for absorbing noise, stress and strain therebetween and mounting means for connecting said support bar to said rigid structural member comprising, fastening means secured to a surface of said elongated rigid structural member and means fixidly secured to said support bar for receiving said fastening means wherein said rigid structural member is substantially anchored to said support bar.
Claim 3
Dependent Claim
33 words
A composite expansion joint assembly according to claim 1 wherein said elastic means comprises a generally flat body of a resiliently yieldable material interposed between said rigid structural member and said support bars.
Claim 4
Dependent Claim
29 words
A composite expansion joint assembly according to claim 2 where in said mounting means detachably mounts said resiliently yieldable body between said rigid structural member and said support bars.
Claim 5
Dependent Claim
50 words
A composite expansion joint assembly according to claim 3 wherein said detachable mounting means include angle membErs attached to the opposite sides of each of said support bars and fastening means extending through portions of said angle members and said body removably securing the same to said rigid structural member.
