Deck panel for roof and floor structures

Claim 1

A combination structure for buildings and the like comprising: a. a foundation; b. a plurality of wall panels emplaced on said foundation; each said wall panel having a peripheral metallic skeleton that is structurally adequate to bear its share of the design load for said building such that said wall panels alone are sufficient without requiring supplemental structural supports, and a lightweight concrete center portion that has a desired facade and interior finish and that adds its structural strength, particularly in compression, to said wall panel for a large additional safety factor; said wall panels being welded together at their adjacent metallic peripheral skeletons; and c. a plurality of deck panels emplaced, respectively, adjacent each other and connected to said wall panels at the desired height; each said deck panel including a continuous peripheral skeleton formed of a plurality of connected together metallic members; said skeleton having a structural strength adequate to bear a predetermined design load without requiring any additional supports; a lightweight concrete center portion carried by said peripheral skeleton; said concrete center portion including a downwardly depending beam of lightweight concrete extending longitudinally thereof; a plurality of first and second panel reinforcing bars embedded in said concrete center portion and connected with said peripheral skeleton; said plurality of first and second panel reinforcing bars extending longitudinally and transversely of said panels; and a plurality of beam reinforcing bars embedded in and extending longitudinally of said depending beam of lightweight concrete; said plurality of beam reinforcing bars being unprestressed at the time of pouring said concrete center portion such that said panel has a flat upper surface that does not bow upwardly in the longitudinal center thereof.
