Reinforced concrete part for producing foundations of buildings

A foundation for buildings, comprising:

• a plurality of reinforced concrete sections, each reinforced concrete section comprising:
• two pre-cast floor elements each comprising a substantially rectangular concrete slab and at least one lattice girder made of steel attached to the concrete slab, said lattice girder having a top boom spaced from the concrete slab, the two pre-cast floor elements arranged in a laterally reversed manner so that their concrete slabs are situated parallel to and at a distance from one another and their lattice girders face one another;
• and
• at least one transition piece extending rigidly and substantially horizontally between the top booms of the facing lattice girders to thereby rigidly attach the two pre-cast floor elements to one another to form a single prefabricated part;
• wherein the rectangular concrete slabs each have a pair of opposite longitudinal edges giving each reinforced concrete section four longitudinal edges;
• wherein the plurality of reinforced concrete sections are situated in a position in which they are each standing on two of their longitudinal edges and each section substantially abuts another of the sections;
• and
• the space between the concrete slabs of the reinforced concrete sections is filled with site-mixed concrete.
