Abstract
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. A plurality of metal rods are welded together and extend between each separator and across the ends of the separators forming a first metal grid. A second metal grid is held above the first metal grid by a plurality of metal rods extending partially into the top part of the mold. 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. Upstanding pins on the bottom part locate the top part of the mold.

Claim 1
Independent Claim
213 words
A mold for producing a floor with a smooth top surface and having integrally joined concrete slabs for supporting animals comprising: a bottom part with a smooth finish top surface extending thereacross to form said smooth top surface of said floor, said bottom part including a plurality of longitudinally extending ridges extending upwardly from said top surface, said bottom part includes a separate recess formed in said top surface between each of said ridges, each recess is concave and includes opposite longitudinally extending and radiused edge portions blended into said ridges; a top part removably mounted atop said bottom part, said top part includes a pair of sidewalls and end walls connected together forming an enclosure for holding poured concrete, said top part further includes spaced apart slab separators having an elongated configuration extending in the direction of said sidewalls, said separators are spaced from said end walls allowing concrete to extend completely around each separator forming said integrally joined concrete slabs, each separator has a bottom end contacting said ridges of said bottom part and opposite side surfaces diverging from said bottom end allowing said separators to be withdrawn upon solidification of concrete within said mold and surrounding said separators; locating means on said mold to align said ridges with said separators.
