Reinforcing element for built-ins in concrete constructions
First Claim
1. A device for strengthening concrete structures, which bridges weakened zones using structural elements which can be inserted locally, wherein, in addition to the conventional reinforcement, and before pouring in the concrete, built-ins (20) are enclosed by at least one structural element (1) which transmits the forces, and hence improves the concrete construction weakened by said built-ins (20), in that said structural element (1) increases the local static shear-carrying capability in the region of said built-ins (20), wherein said structural element (1) generates at least one force model which forms force-neutral zones (31) for said built-ins (20), said zones defining the position of said built-ins (20), as a result of which the weakenings caused to the concrete construction by said built-ins (20) are at least minimized.

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.
