<p>BUILDING DECK CONSTRUCTION A poured building deck structure having sheet metal structural shapes of a box section as sub-purlins, the upper face of the box section having open slots for engaging sheet metal clips which are secured in the box section when the axis of the clip and the box section are about 90.degree. to each other, the clip engaging and holding formboard adjacent the top face of the box section and the clips then extending substantially vertically upward and then extending substantially horizontally engaging the poured concrete above the formboard to provide uplift resistance to the composite structure. The poured building deck structure of this invention is extremely versatile providing a very economical insulating and fireproof poured gypsum deck structure. The combination structure of this invention permits the use of thinner formboard and thinner concrete, providing lighter weight decks than previously available.</p> |
