Abstract
An elongated elastomeric strip has means along the longitudinal edge for fastening to a receiving element secured in a roadbed. The fastening element comprises at least one set of retaining members, each having a head portion at least in part embedded and bonded securely in the elastomeric strip and a projecting portion depending from the strip. The retaining members are arranged so that the projecting ends of some of them face oppositely to the projecting ends of the others of them, thereby being relatively movable toward and away from each other under deformation of said strip and cooperate to resiliently clamp onto the receiving element. The projecting ends of the retaining members are preferably claw-like.
Claims21
An expansion joint assembly for covering gaps between adjacent sections of vehicular road beds, bridges and the like comprising an elongated elastomeric strip having a plurality of retaining members embedded at least in part in and bonded securely to the elastomeric strip along the longitudinal edges thereof, said retaining members having engaging means extending from said strip and being arranged so that the engaging means of at least one of said retaining members face in one direction and the engaging means of at least one of the other retaining member faces in another direction so as to cooperatively move under deformation of said strip to detachably engage with a receiving element located in said road bed.
