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.

Abstract: An anchor rail has a base body having a longitudinal groove that extends along a longitudinal center line of the anchor rail, and a rail back, fixed with an anchor, on the side opposite the longitudinal groove. The base body has a one front side perpendicular to the longitudinal center line and fixed with an end plate that protrudes beyond the rail back to the side of the base body facing away from the longitudinal groove and supports an anchoring element, which extends from the side of the end plate on which the base body is arranged. The end plate is flush to the front side and does not protrude into the base body. For a building structure with a concrete member, into which an anchor rail is cast, the longitudinal groove is on a first router side of the concrete member. The end plate runs along a second side of the concrete member and the anchoring element protrudes into the concrete member.
