摘要： A mold of uniform thickness of nonmagnetic material for molding steel-reinforced laminar self-curing semifluid material into open side hollow bodies of substantially uniform thickness including a plurality of magnets distributed around the nonmolding side of the mold for urging by magnetic attraction through the mold perforated expanded or reticular steel reinforcement material into intimate and uniform engagement with each of a plurality of semicured layers of the molding material sequentially applied to the molding side of the mold to form a laminar steel-reinforced body of predetermined substantially uniform thickness when the material is cured.
