Claim 3

The building deck structure of claim 1 wherein the outer open ends of corrugations of said corrugated sheet metal form are closed to retain poured concrete by a closure angle having one leg fastened to the top of the corrugated sheet metal form and the other leg extending downwardly adjacent said open ends in sufficiently close relationship to prevent passage of wet concrete.

Claim 4

The building deck structure of claim 1 wherein said edge bracket comprises an edge angle having one leg fastened in relation to said corrugated sheet metal form and extending outwardly to the desired relationship to the building line or opening, the other leg extending upwardly to retain poured concrete.

Claim 5

The building deck structure of claim 3 wherein said other leg extends upwardly beyond the level of concrete to be poured to serve as a toe rail at the edge of the deck or opening.

Claim 6

The building deck structure of claim 1 wherein said edge bracket comprises an upwardly extending U-shaped shape having its bottom fastened in relation to said corrugated sheet metal form and extending outwardly to the desired relationship to the building line or opening, the top end of the legs of said U-shaped form being a height to be even with the top of the concrete when poured.

Claim 7

The building deck structure of claim 5 wherein a temporary toe rail is provided by a flat board secured in the opening in said U-shaped shape and extending beyond the top end of the legs a desired distance.

Claim 8

The building deck structure of claim 1 wherein said edge bracket comprises two opposing U-shaped shapes fastened together at their bottoms and having one of their sides fastened in relation to said corrugated sheet metal form with one U-shape opening outwardly and the opposing U-shape opening inwardly, the open end of the outwardly opening U-shape extending outwardly to the desired relationship to the building line or opening and providing attachment means for a temporary formboard for the poured concrete.

Claim 9

The building deck structure of claim 7 wherein said outwardly extending U-shape provides means for anchoring for the building wall closure after removal of the formboard.

Claim 10

The building deck structure of claim 7 wherein the inwardly opening U-shape provides attachment means for concrete anchors.

Claim 11

A poured concrete building deck comprising: a corrugated sheet metal form deck supported by structural girders and spandrels and comprising a major corrugated sheet metal form deck portion and two minor sheet metal form portions having corrugations at about 90° to the corrugations of said major deck portion, said major deck portion having its outer ends which are perpendicular to the corrugations spaced a distance corresponding to the adjustability of an edge bracket inside of the desired building line and its outer sides which are parallel to the corrugations spaced inside the spandrels, said minor form portions extending outwardly from each of said outer sides of said major deck portion over the spandrel and having their outer ends which are perpendicular to their corrugations a distance corresponding to the adjustability of an edge bracket inside of the desired building line and their inner ends supported by open troughs at each of said outer sides of said major deck portion; edge brackets fastened to said major and minor corrugated metal form deck and forms outer ends, respectively, and outwardly to the desired building line and providing means to retain poured concrete to the desired height; metal reinforcing above said metal deck and forms; and poured concrete adjacent and above said metal deck and forms embedding said metallic reinforcing and extending to said edge brackets to cover the desired concrete deck area.

Claim 12

A poured concrete building deck comprising: a corrugated sheet metal form deck supported by structural girders and spandrels and comprising a major corrugated sheet metal form deck portion and two minor sheet metal form portions having corrugations at about 90° to the corrugations of said major deck portion, said major deck portion having its outer ends which are perpendicular to the corrugations spaced a distance corresponding to the adjustability of an edge bracket inside of the desired building line and its outer sides which are parallel to the corrugations spaced inside the spandrels, said minor form portions extending outwardly from each of said outer sides of said major deck portion over the spandrel and having their outer ends which are perpendicular to their corrugations a distance corresponding to the adjustability of an edge bracket inside of the desired building line and their inner ends supported by open troughs at each of said outer sides of said major deck portion; edge brackets fastened to said major and minor corrugated metal form deck and forms outer ends, respectively, and outwardly to the desired building line and providing means to retain poured concrete to the desired height; metal reinforcing above said metal deck and forms; and poured concrete adjacent and above said metal deck and forms embedding said metallic reinforcing and extending to said edge brackets to cover the desired concrete deck area.

Claim 13

The poured concrete building deck of claim 10 wherein the outer open ends of corrugations of said corrugated sheet metal forms and deck are closed to retain poured concrete by a closure angle having one leg fastened to the top of the corrugated sheet metal forms and deck and the other leg extending downwardly adjacent said open ends in sufficiently close relationship to prevent passage of wet concrete.

Claim 14

The poured concrete building deck of claim 10 wherein said edge bracket comprises an edge angle having one leg fastened in relation to said corrugated sheet metal forms and deck and extending outwardly to the desired relationship to the building line or opening, the other leg extending upwardly to retain poured concrete.

Claim 15

The poured concrete building deck of claim 12 wherein said other leg extends upwardly beyond the level of concrete to be poured to serve as a toe rail at the edge of the deck or opening.

Claim 16

The poured concrete building deck of claim 10 wherein said edge bracket comprises an upwardly extending U-shaped shape having its bottom fastened in relation to said corrugated sheet metal forms and deck and extending outwardly to the desired relationship to the building line or opening, the top end of the legs of said U-shaped form being a height to be even with the top of the concrete when poured.

Claim 17

The poured concrete building deck of claim 14 wherein a temporary toe rail is provided by a flat board secured in the opening in said U-shaped shape and extending beyond the top of the legs a desired distance.

Claim 18

The poured concrete building deck of claim 10 wherein said edge bracket comprises two opposing U-shaped shapes fastened together at their bottoms and having one of their sides fastened in relation to said corrugated sheet metal forms and deck one U-shape opening outwardly and the opposing U-shape opening inwardly, the open end of the outwardly opening U-shape extending outwardly to the desired relationship to the building line or opening and providing attachment means for a temporary formboard for the poured concrete.

Claim 19

The poured concrete building deck of claim 16 wherein said outwardly extending U-shape provides means for anchoring for the building wall closure after removal of the formboard.
