ABSTRACT:
A sliding closure for a roadway expansion joint crossing has on the first part of the roadway (1) a sliding face (5) with a curved segment (7) and an adjoining level segment (8) running parallel to the driving surface (4). Resting flatly on this sliding face is a sliding plate (10) of elastomeric material and of uniform thickness. The sliding plate (10) is bolted onto the second part of the roadway (2) and bridges with a level section (12) a gap (11) between the first and second parts of the roadway (1, 2). In the level section (12), the sliding plate (10) is reinforced by a flexurally rigid steel plate (14). In the section resting on the curved segment (7), the reinforcement of the sliding plate (10) consists of a thin, flexible plate (15). Fastened on the first part of the roadway (1) is a tongue plate (32), which overlaps the sliding plate. This design enables the closure for the roadway expansion joint to be produced inexpensively, is simple to service, and has a shallow construction depth and a high corrosion resistance.
