Multifunctional rebar support system for reinforcement of concrete structures
A rebar support system used in the reinforcement of concrete structures is disclosed, comprising a rebar support tower and a rebar support base, individually capable of holding rebar members at a predefined height within a range of possible heights, the two further capable of acting together in tower-base duplex fashion in the formation of multilevel rebar grids. The rebar tower has four legs between which there are defined two intersecting passages, the legs being open-ended at the bottom and forming bidirectional arches at the top of said intersecting passages, said rebar tower further having a saddle formation at its apex. The rebar tower provides a tapered and angled foot profile at the bottom of each leg to minimize the area of contact when used with a concrete form, thereby reducing rebar support footprints after form removal. The rebar base comprises a platform with centrally rising bidirectional saddle formations, the intersecting passages and saddle formations of tower and base providing means for receiving the intersecting segments of rebars which are normal to each other. Locking insert hooks and guide tabs incorporated in the rebar base, and hook receptacles, guide ridges and restraining surfaces incorporated in the rebar tower provide complementary means for the attachment of the two structures to form a rigid, yet detachable tower-base assembly in multiple rebar grid configurations. The rebar base provides a stable support means when used individually or in tower-base assemblies on granular surfaces, such as sand or gravel beds.
