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.degree. to 75.degree. 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.
