(57) A form for a concrete slab which consists of a series of similarly shaped steel plates that are held in predetermined spaced relationship by a series of special rebars, (special nuts are provided) before the slab is poured. The slab is crisscrossed by rebars which extend through the form to accurately locate the remaining steel plates as weil as to prevent excessive cracking of the slab.
