Abstract

In a method for producing a plurality of concrete cast elements of prestressed concrete, in particular for producing of railway sleepers, in a long bed which is a multiple of the length of a concrete cast element, in which separating elements are installed in the long bed to define the length of each of the concrete cast elements to be casted, a first and a second separating element for defining the length of a concrete cast element together with a tensioning device with tensioning elements for tensioning the concrete cast element between the two separating elements are mounted in the long bed, whereupon the concrete cast element is cast between the two separating elements and is at least partially hardened in the long bed.
