ABSTRACT:
A method and mold for producing a concrete slotted floor for supporting animals. The mold includes a bottom part with a smooth top surface with lengthwise extending ridges formed thereon. The top part of the mold locks to the bottom part and includes a plurality of parallel slab separators seatable upon the ridges. The top part includes end walls and side walls defining an enclosure for receiving the poured concrete. The slab separators are spaced apart from the end walls allowing the concrete to extend completely around each separator to form integrally joined concrete slabs. Concrete is poured into the top part of the mold between each separator and across the ends of the separators. The mold is vibrated and the concrete is allowed to solidify. The top part of the mold is then lifted upwardly and the solidified concrete is removed and turned over in order that the smooth surface of the concrete contacting the bottom part of the mold faces upwardly. In the preferred embodiment, a wooden insert is removably mounted to the concrete slotted floor and positioned in an upwardly facing recess formed in the floor during the molding thereof.
