Bridging of expansion joints in roadways of bridges, streets, runways and the like
Abstract
Abstract The edges of the expansion joint between two roadway sections are terminated with adjoining edge profiles, respectively. One or more longitudinal retaining members pass parallel to said edge profiles and are connected to the latter and to each other by means of flexible sealing members. Each retaining member is fixedly connected with two parallel supporting traverses disposed in the direction of the roadway in a recess below the edge profiles. Each of said traverses slidably rests on two sliders supported on fixed mounting plates. In addition to the system of elastic sealing members, a system of elastic spring members is provided. The latter members act between the traverses and the edges of the expansion joint. By the combined elastic systems, the retaining members (if more than 1) are approximately equally spaced from one another. The retaining members (as a unit) are held approximately in the middle between the edge profiles in any position of the expansion joint.
