Abstract: Construction elements (21) are disclosed which allows potential weaknesses of a concrete structure (10) caused by recessed parts (20), e.g. media lines, to be nearly or fully eliminated. Said construction elements (21) consist of two anchoring devices (2) and an intermediate draw bar (2). A mounting device (4) is fixedly or removably provided in the area of the draw bar such that the hollow space for running the media lines, for example, is defined. The disclosed construction elements (21) can be integrated in the planning phase and/or shortly before casting the concrete.
