The spacer for reinforcing elements in concrete constructions comprises a profiled beam with a number of bearers slipped thereon. Each one of said bearers is in the form of an A in the lateral view and is provided in its upper portion with a transversal web in order to form an inserting opening for said beam. Said beam has a double-T profile having a web which is provided at its foot end with a larger foot flange and in its upper half with a transversal flange having a somewhat greater length than the inner width of said inserting opening at that point, and whose head serves as a supporting surface for said reinforcing elements. Such a spacer provides a great stability and can be manufactured with relatively little expenditure and material. Moreover, the upper portion of said bearers serves as an abutment for a precise layout of said reinforcing elements. (SE/as 06.05.93)
