Abstract
In the case of a bridging arrangement for expansion joints in the carriageways of bridges or the like having a plurality of parallel plates (1-5) which are adjacent to the surface of the carriageway, run at right-angles to the direction of the carriageway and are supported on bars (6-10) which bridge the joint gap and are displaceably mounted in the edges (14, 15) of the joint, each plate is rigidly connected to two or more bars, but each bar is rigidly connected to not more than one plate. The spacings of the plates is controlled by means of elastomeric bearing members (19), the bars being supported by bearing members of that type that are on one or both of the plates and the two outer bars being supported likewise by bearing members of that type which are on the two edges (14, 15) of the joint, each on a different edge. This type of arrangement of the bearing member described results additionally in an especially even distribution of the vertical loads.
