Abstract
Abstract This invention relates to an expansion joint seal of the type commonly used in sealing adjacent deck panels of a bridge, although it could be used in any case where a seal for an expansion joint between two panels is required. The seal consists essentially of an elastomer strip with transversely extending holes adapted to receive load-bearing bars in sliding relation so that as the panels expand and contract, the elastomer can follow the expansion and contraction and slide relative to the loadbearing bars. The particular advantage of the construction is that the elastomer moves with respect to the bar for substantially the full extent of the width of the seal so that the elastomer is stressed over substantially its full width as the joint expands and contracts.

Claim 1
Independent Claim
201 words
An expansion joint seal for the space between a pair of juxtaposed panels comprising an elongated strip of elastomer material with opposed side marginal portions each secured to opposed marginal edge portions of a pair of juxtaposed panels, said strip being formed with a series of spaced apart transversely extending openings, a series of load-bearing bars, each of said openings containing one of said bars, each of said bars being shorter than and slidable within its respective opening whereby said strip and said bars can move relatively to each other as said strip expands or contracts in width, said bars each having a length extending between side marginal portions of said strip whereby each end overlies a marginal edge portion of said pair of juxtaposed panels, means for securing one end of each of sAid load-bearing bars with respect to said strip at one side marginal portion of said strip, said load-bearing bars in adjacent openings being secured with respect to said strip at opposite marginal portions of said strip, the spacing of adjacent bars being close, the free end of each load-bearing bar being between the secured end of its two adjacent load-bearing bars and thereby restrained against vertical movement.

An expansion joint seal for the space between a pair of juxtaposed panels comprising an elongated strip of elastomer material with opposed side marginal portions each secured to opposed marginal edge portions of a pair of juxtaposed panels, said strip being formed with a series of spaced apart transversely extending openings, a series of load-bearing bars, each of said openings containing one of said bars, each of said bars being shorter than and slidable within its respective opening whereby said strip and said bars can move relatively to each other as said strip expands or contracts in width, said bars each having a length extending between side marginal portions of said strip whereby each end overlies a marginal edge portion of said pair of juxtaposed panels, means for securing one end of each of sAid load-bearing bars with respect to said strip at one side marginal portion of said strip, said load-bearing bars in adjacent openings being secured with respect to said strip at opposite marginal portions of said strip, the spacing of adjacent bars being close, the free end of each load-bearing bar being between the secured end of its two adjacent load-bearing bars and thereby restrained against vertical movement.
Claim 3
Dependent Claim
197 words
An expansion joint seal comprising an elongated strip of elastomer material with opposed side marginal portions each adapted for securement to an edge of a pair of juxtaposed panels, said strip being formed with a series of spaced apart transversely extending openings, a series of load-bearing bars, each of said openings being adapted to receive one of said bars in sliding relation, each of said openings being longer than its respective bar whereby said strip and said bars can move relatively to each other as said strip expands or contracts in width, said bars each having a length adapted to extend to said side marginal portions of said strip whereby in use each end can be caused to overlie an edge of a pair of juxtaposed panels, means for securing one end of each of said load-bearing bars with respect to said strip at one side marginal portion of said strip, load-bearing bars in adjacent openings being secured with respect to said strip at one marginal portion of said strip and in which means are provided at the other marginal portion of said strip for restraining the vertical movement of the free ends of said load-bearing bars.
Claim 4
Dependent Claim
197 words
An expansion joint seal comprising an elongated strip of elastomer material with opposed side marginal portions each adapted for securement to an edge of a pair of juxtaposed panels, said strip being formed with a series of spaced apart transversely extending openings, a series of load-bearing bars, each of said openings being adapted to receive one of said bars in sliding relation, each of said openings being longer than its respective bar whereby said strip and said bars can move relatively to each other as said strip expands or contracts in width, said bars each having a length adapted to extend to said side marginal portions of said strip whereby in use each end can be caused to overlie an edge of a pair of juxtaposed panels, means for securing one end of each of said load-bearing bars with respect to said strip at one side marginal portion of said strip, load-bearing bars in adjacent openings being secured with respect to said strip at one marginal portion of said strip and in which means are provided at the other marginal portion of said strip for restraining the vertical movement of the free ends of said load-bearing bars.
Claim 5
