Abstract
A modular lightweight structural panel is made of a lightweight expanded plastic filler reinforced by wire lattice structures. A number of long, narrow filler elements are interleaved with a number of substantially flat lattice structures to form a laminated panel subassembly with corresponding surfaces of the filler elements collectively forming substantially planar surfaces of the panel core. The subassembly is laterally compressed, in a direction perpendicular to the planes of laminations, to thereby force each of the lattice structures to be pressed into and partially embedded in mutually contiguous surfaces of adjacent ones of the filler elements. While in such compressed condition, a number of cross-members are fixed to side portions of the several lattice structures that protrude beyond the panel surfaces to thereby hold the assembly in its pressed condition with the lattice structures embedded in the filler elements and the surfaces of adjacent filler elements in close physical contact with one another. The completed panel assembly is thereafter coated with a suitable mixture of concrete, plaster, or the like.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
