Claim 1
Independent Claim
166 words
A building deck structure comprising: a spaced series of parallel sheet metal structural shapes which are symmetrical about a bisecting plane through a central web having a central web, two diagonal legs projecting downwardly from one end of said web forming an included angle of about 30° to about 90° between said legs and having its vertex at the bottom of the web, said diagonal legs having a vertical height of about 11/8 to about 10 inches, each diagonal leg having a leg projecting downward at its extremity in a plane substantially parallel to said web, said legs being substantially parallel, each of said parallel legs having flanges extending outwardly at their extremity, a closure side extending between the extremities of said flanges enclosing the area formed by said diagonal sides, said parallel sides and said closure side, and a stiffening member at the other end of said web; and decking assembly having its lower surface resting on said flanges and extending between adjacent structural shapes.
Claim 2
Dependent Claim
166 words
A building deck structure comprising: a spaced series of parallel sheet metal structural shapes which are symmetrical about a bisecting plane through a central web having a central web, two diagonal legs projecting downwardly from one end of said web forming an included angle of about 30° to about 90° between said legs and having its vertex at the bottom of the web, said diagonal legs having a vertical height of about 11/8 to about 10 inches, each diagonal leg having a leg projecting downward at its extremity in a plane substantially parallel to said web, said legs being substantially parallel, each of said parallel legs having flanges extending outwardly at their extremity, a closure side extending between the extremities of said flanges enclosing the area formed by said diagonal sides, said parallel sides and said closure side, and a stiffening member at the other end of said web; and decking assembly having its lower surface resting on said flanges and extending between adjacent structural shapes.
Claim 3
Dependent Claim
122 words
The building deck structure of claim 1 wherein said building deck structure comprises: gypsum formboard resting on said flanges and extending between adjacent structural shapes; rigid synthetic polymer foam having an underside adjacent the upper side of said gypsum formboard and having spaces vertically communicating from the upper side of said formboard to the upper side of said foam, said spaces having an area of more than about 5 percent of the area of the upper side of said formboard; and poured concrete adjacent the upper side of said foam and around said stiffener to prevent uplift and extending through said spaces contacting the upper side of said gypsum formboard, said concrete completing drying by escape of moisture through said gypsum formboard.
Claim 4
Dependent Claim
20 words
The building deck structure of claim 1 wherein said structural shape central web is about 3/8 to about 5/8 inch.
Claim 5
Dependent Claim
24 words
The building deck structure of claim 1 wherein said structural shape diagonal legs have a vertical depth of about 11/8 to about 4 inches.
Claim 6
Dependent Claim
24 words
The building deck structure of claim 1 wherein said structural shape diagonal legs have a vertical depth of about 4 to about 10 inches.
Claim 7
Dependent Claim
20 words
The building deck structure of claim 1 wherein said structural shape parallel legs are about 3/8 to about 4 inches.
Claim 8
Dependent Claim
18 words
The building deck structure of claim 1 wherein said structural shape stiffening member is an inverted isosceles triangle.
Claim 9
Dependent Claim
17 words
The building deck structure of claim 1 wherein said structural shape stiffening member is a stiffener flange.
Claim 10
Dependent Claim
43 words
The building deck structure of claim 1 wherein said structural shape closure side is spaced from said flanges by box sides extending from the extremity of each flange to each end of said closure side in a plane substantially parallel to said web.
Claim 11
Dependent Claim
15 words
The building deck structure of claim 1 wherein said decking assembly comprises prefabricated deck structures.
Claim 12
Dependent Claim
21 words
The deck structure of claim 10 having grouting between said prefabricated deck structures and surrounding said stiffening member providing uplift resistance.
