Abstract
The present invention relates to a base plate for a rail fastening point, in which a rail for a rail vehicle is fastened on a substrate. The base plate includes a main body with a rib structure, which from the underside assigned to the substrate is formed into the main body of the base plate and is formed by ribs and by recesses which surround the ribs and are open to the underside, and to a rail fastening point. The base plate for a rail fastening point can be manufactured in a simple, cost-effective manner and makes it possible to avoid by simple means pressing into a soft substrate. This is achieved in that the base plate additionally includes a cover fastened to the base plate after the manufacture of the main body, which covers the rib structure on the underside of the main body at least in sections.
