ABSTRACT:
A device for bridging expansion joints in bridges or the like is provided with parallel lamellae arranged at right angles to the longitudinal axis of the traffic route. The lamellae are supported on at least two inclined traverses which are pivoted and movably supported at both sides in the joint edges, which bridge said joint diagonally with respect to the longitudinal axis, and are rotatably and movably guided in sliding drag bearings at the bottoms of the lamellae. The inclined traverses are arranged parallel to each other, whereby the support width of the lamellae is always uniform. At least one longitudinal traverse which is movably connected the longitudinal direction with each lamellae via sliding bearings fixed at the bottoms of the lamellae is provided for, preferably at the edge, for taking up the forces which inevitably occur due to movements of the bridge superstructure.
