Abstract
Abstract A structural deck especially suited for floors and roofs. It comprises an undulating metal structure having substantially horizontal bottom walls and top walls interconnected by downwardly and outwardly tapered, substantially flat side walls. Doved-tailed flanges are provided on the top portions of the side walls to interlock with concrete poured above. The inner surfaces of the dove-tailed flanges serve as supports for accessories, such as insulation, lighting fixtures and the like. The bottom portions of the side walls have outwardly extending doved-tailed flanges serving as supports for readily detachable closure caps having varying shapes, especially for aesthetic purposes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
151 words
A structural deck for supporting concrete floors in interlocking relationship, comprising an undulating symmetrical and reversible structure having substantially horizontal bottom walls and top walls having inwardly extending central ribbed portions of identical construction, said bottom and top walls being of identical but inverted construction interconnected by downwardly and outwardly tapered, substantially flat sidewalls, the top portions of said sidewalls having immediately adjacent inwardly extending dove-tailed flanges projecting directly below the side portions of said top walls to serve as interlocking elements and supports for articles that may be suspended inside the deck, the bottom portions of said sidewalls having immediately adjacent inwardly extending dove-tailed flanges projecting directly above the side portions of said bottom wall so as to make the deck of inverted symmetrical construction throughout, and readily detachable closure means suspended by said last-mentioned flanges for forming closed cells with at least some of the undulations of said structure.
Claim 2
Dependent Claim
151 words
A structural deck for supporting concrete floors in interlocking relationship, comprising an undulating symmetrical and reversible structure having substantially horizontal bottom walls and top walls having inwardly extending central ribbed portions of identical construction, said bottom and top walls being of identical but inverted construction interconnected by downwardly and outwardly tapered, substantially flat sidewalls, the top portions of said sidewalls having immediately adjacent inwardly extending dove-tailed flanges projecting directly below the side portions of said top walls to serve as interlocking elements and supports for articles that may be suspended inside the deck, the bottom portions of said sidewalls having immediately adjacent inwardly extending dove-tailed flanges projecting directly above the side portions of said bottom wall so as to make the deck of inverted symmetrical construction throughout, and readily detachable closure means suspended by said last-mentioned flanges for forming closed cells with at least some of the undulations of said structure.
