Abstract
Abstract An insulated decking structure and method using a sheet metal structural shape as a purlin or sub-purlin which is symmetrical about a vertical bisecting plane and having a central vertical web, two legs projecting downwardly from the bottom of said web at an angle of about 45° to 75° to the horizontal, each leg having a substantially horizontal flange projecting outwardly at its lower extremity, and a stiffening member at the upper edge of the web. Poured concrete insulated deck structures utilize a series of the sheet metal structural shapes with gypsum formboard resting on the horizontal flanges and extending between adjacent structural shapes, rigid synthetic polymer foam having an underside adjacent the upper side of the gypsum form-board and having spaces vertically therethrough having an area of more than about 5 percent of the area of the upperside of the formboard, and poured concrete adjacent the upper side of the foam and through the above defined spaces and around the stiffener to prevent uplift. A precast insulated deck structure utilizing the sheet metal structural shape with the insulating slab resting on the horizontal flanges and extending between adjacent structural shapes with grouting between said precast slabs and around said stiffener to prevent uplift.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
184 words
A poured concrete insulated deck structure comprising: a series of parallel sheet metal structural shapes which are symmetrical about a vertical bisecting plane having a central vertical web, two legs projecting downwardly from the bottom of said web at an angle of about 45° to about 75° to the horizontal, each leg having a substantially horizontal flange projecting outwardly at its lower extremity, and a stiffening member at the upper edge of said web; gypsum formboard resting on said horizontal flanges and extending between adjacent structural shapes; rigid synthetic polymer foam having an underside adjacent the upper side of said gypsum form-board 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 2
Dependent Claim
184 words
A poured concrete insulated deck structure comprising: a series of parallel sheet metal structural shapes which are symmetrical about a vertical bisecting plane having a central vertical web, two legs projecting downwardly from the bottom of said web at an angle of about 45° to about 75° to the horizontal, each leg having a substantially horizontal flange projecting outwardly at its lower extremity, and a stiffening member at the upper edge of said web; gypsum formboard resting on said horizontal flanges and extending between adjacent structural shapes; rigid synthetic polymer foam having an underside adjacent the upper side of said gypsum form-board 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.
