ABSTRACT:
This invention relates to an apparatus for molding slotted concrete floor sections. The apparatus forms the concrete floor sections in an inverted position so as to avoid the need for hand finishing of the upper surface of the molded concrete floor sections. The apparatus comprises a base, opposing pairs of interconnected upstanding side and end walls connected to the base and a plurality of elongate spaced apart and substantially parallel ridges connected to and projecting upwardly from the base. Attached to and overlying the ridges are a plurality of elongate keystone shaped dividers removably mounted on and extending upwardly from the ridges with the upper surface being in a substantially common plane with the upper surfaces of the side and end walls. The dividers are attached to the apparatus by downwardly extending connector means which extend through holes in the ridges to a force applying means positioned below the base and operatively associated with the connecting means for supplying a downward force from below the base of the apparatus.
