<p>A building system for a reinforced concrete floor includes forms made of foam plastic material such as expanded polystyrene for receiving liquid concrete. The reinforcing steel bars are mutually connected to form trusses which are supported upon vertical, reinforced concrete columns at the corners of each bay, and in some cases upon one another. After the trusses are in place, the forms are lifted into position and supported by the trusses, following which the concrete is poured into or upon the forms and at least partially encloses the steel trusses. The invention is disclosed in the context of a flooring system of the type known in the art as One-Way Joist, but may be adapted to virtually any other system of reinforced concrete floor construction. In any event, the foam forms remain in place, effectively becoming part of the structure, after the concrete has hardened.</p> |
