ABSTRACT:
Disclosed herein is a cast or molded structural panel having two plates or sheets integrally joined to an intermediate zone. The intermediate zone is formed either of a cross corrugated panel or a double tray structure between the plates. The cross corrugated panel may be regarded as having a first set of corrugations perpendicularly intersecting a second set of corrugations. The double tray structure may be described as two arrays of hollow pyramids whose bases are joined to one of the sheets. One array of pyramids fits in an interdigitally complementary fashion into the other array of pyramids, and the two trays are integrally joined at the areas of contract between pyramids. Filler material may occupy the cavities defined by the intermediate zone and the plates. In the case of an apertured intermediate zone, the fillter will form a continuous lattice-like structure interwoven with this zone.
