Abstract
A support plate for bridges and ramps having a roadway or a walkway has two longitudinal supports defining lateral sides of the support plate in the longitudinal direction of the support plate. A plurality of transverse members having acting surfaces constituting the roadway or walkway and having a first and a second free end is connected with the first and the second free ends to the longitudinal supports so as to be perpendicular to the longitudinal direction and parallel to one another. Each of the acting surfaces is slanted relative to the longitudinal direction and displaced by an increment of displacement with respect to neighboring ones of the acting surfaces in a stepwise manner over the height of the lateral sides.
