Abstract
Abstract Corrugated steel plate is formed from a flat plate stock and has a length of at least about 12 feet, a corrugation pitch of at least about 12 inches, and a corrugation depth of at least four inches. The plate has thicknesses of up to one-half inch and more. Also disclosed are structures such as tunnel-type, heavy load-supporting structures defined by upright and horizontal structure portions which extend over no more than about 180° while being capable of supporting up to 40 feet of ground fill and payload thereon. The corrugated plate can be used singly or as double, spaced-apart plate assemblies which are hollow or filled with concrete or a like material, including steel reinforcing bars for the concrete. The corrugated plate can also be formed into vertical, sectional retaining walls, bin type retaining walls, bridge abuttment walls, flat support surfaces such as bridge decking, open air structures, guard rails, sheet piling, etc.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A high-strength structural steel plate comprising a plurality of parallel, longitudinally extending, generally sinusoidally shaped corrugations defined by altering convex and concave peaks and troughs, the spacing between adjacent peaks and troughs in a direction perpendicular to the plate being at least about 4 inches and the spacing between adjacent peaks in a direction parallel to the plate being at least about 12 inches, the plate having a thickness of no more than about one-half inch, the peaks and troughs having a curvature radius of at least about two inches, and a corrosion resisting coating applied to surfaces of the plate, whereby the plate can be rolled to form the corrugations after the application of the coating from flat sheet metal with the peaks and troughs oriented parallel to the rolling direction.
Claim 2
Dependent Claim
132 words
A high-strength structural steel plate comprising a plurality of parallel, longitudinally extending, generally sinusoidally shaped corrugations defined by altering convex and concave peaks and troughs, the spacing between adjacent peaks and troughs in a direction perpendicular to the plate being at least about 4 inches and the spacing between adjacent peaks in a direction parallel to the plate being at least about 12 inches, the plate having a thickness of no more than about one-half inch, the peaks and troughs having a curvature radius of at least about two inches, and a corrosion resisting coating applied to surfaces of the plate, whereby the plate can be rolled to form the corrugations after the application of the coating from flat sheet metal with the peaks and troughs oriented parallel to the rolling direction.
