Abstract
A concrete floor system includes undulating sheet metal formwork for forming concrete slabs with one or more concrete ribs. The system also provides a unique type of bar chair which allows reinforcement in the form of steel rods, for example, to be dropped in place, thereby minimizing the labor required in installing the formwork.
