Abstract: A concrete construction element has a concrete base body with at least one flat side and an end face. An anchor rail is embedded in the concrete base body. A reinforcement component is provided that has a plate embedded in the concrete base body at a side of the anchor rail which is facing toward the end face of the concrete base body. The reinforcement component has two anchors fixedly connected to the plate, wherein the two anchors extend away from the plate to a side of the anchor rail which is facing away from the plate. The two anchors each have an end facing away from the plate, wherein the end has an anchoring section, wherein the anchoring section forms an undercut in a direction toward the plate.

Abstract: A fastening rail for embedding into a concrete element has one rail back, two rail lips and two rail longitudinal sides disposed opposite one another. The rail lips delimit a slot between them. The fastening rail is realized in an anchorless manner and forms at least one undercut from the rail back in the direction of the outside of the rail lips. To improve anchoring in concrete, the rail back has profiling on its outside which is remote from the rail lips. The fastening rail is advantageously embedded into a concrete element such that the outside of the rail lips lies flush with the surface of the concrete element. A method for making a fastening rail includes producing a profiling in at least one central region of a top side of a metal plate and reshaping the metal plate to form the rail back, rail longitudinal sides and rail lips.
