Abstract
Abstract A composite expansion joint assembly of alternating elastic sealing elements and rigid structural members slidably mounted on transversely extending support beams by tie-down brackets which limit vertical displacement of the structural members. The assembly is prefabricated as a unit and can be readily inserted into and removed from an expansion groove without the customary blocking out.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
157 words
A composite expansion joint assembly comprising: edge members adapted to define the opposite sides of an expansion groove between pavement sections, a plurality of resiliently yieldable elongated sealing elements in side-by-side relation, an elongated rigid structural member interposed between each pair of adjacent sealing elements; support beams extending transversely of said rigid structural members and supporting the same for sliding movement relative thereto; means supporting said support beams for sliding movement relative thereto adjacent at least one end thereof; said rigid structural members, sealing elements, support beams and beam supporting means being adapted for insertion as a unit into said expansion groove, means for mounting said unit in said groove between said edge members with said beam supporting means extending inwardly into said groove from said opposite sides thereof and with said beams confined between the opposite sides of said groove as defined by said edge members, whereby said unit can be vertically displaced in said groove.
Claim 2
Dependent Claim
157 words
A composite expansion joint assembly comprising: edge members adapted to define the opposite sides of an expansion groove between pavement sections, a plurality of resiliently yieldable elongated sealing elements in side-by-side relation, an elongated rigid structural member interposed between each pair of adjacent sealing elements; support beams extending transversely of said rigid structural members and supporting the same for sliding movement relative thereto; means supporting said support beams for sliding movement relative thereto adjacent at least one end thereof; said rigid structural members, sealing elements, support beams and beam supporting means being adapted for insertion as a unit into said expansion groove, means for mounting said unit in said groove between said edge members with said beam supporting means extending inwardly into said groove from said opposite sides thereof and with said beams confined between the opposite sides of said groove as defined by said edge members, whereby said unit can be vertically displaced in said groove.
Claim 3
Dependent Claim
28 words

Claim 12
Dependent Claim
39 words
A composite expansion joint assembly according to claim 1, wherein said mounting means include support bracket means secured to said edge members and extending thErefrom into said groove, said unit being seated on and supported by said bracket means.
Claim 13
Dependent Claim
164 words
A composite expansion joint assembly comprising: edge members adapted to define the opposite sides of an expansion groove between pavement sections, seal locking members extending lengthwise of said assembly, a plurality of resiliently yieldable elongated sealing elements in side-by-side relation between said locking members, an elongated rigid structural member interposed between each pair of adjacent sealing element; support beams extending transversely of said rigid structural members and supporting the same for sliding movement relative thereto; means supporting said support beams for sliding movement relative thereto adjacent at least one end thereof; said rigid structural members, sealing elements, seal locking members, support beams and beam supporting means comprising a unit, means for mounting said unit in said groove between said edge members with said beam supporting means extending inwardly into said groove from said opposite sides thereof and with said beams confined between the opposite sides of said groove as defined by said edge members, whereby said unit can be vertically displaced in said groove.
Claim 14
