Apparatus for precasting concrete products

Apparatus for use in precasting concrete products using a dry mix process wherein green product is capable of standing free and sustaining its own weight and structural integrity almost immediately on completion of formation of the product;

• said apparatus comprising a downardly open upper form section having the desired configuration of the sides of the product to be cast and at least one fill opening at the top, and a plurality of base form sections each with a configuration corresponding to that of the upper form section and each adapted for detachable assembly with and beneath upper form section to close the bottom thereof and to cooperatively define a downwardly closed casting cavity therewithin, each base form section being further adapted to support a free standing green cast product on disassembly of the form section from the upper form section and on removal of the upper form section from the product, and each base section comprising at least two separable parts which cooperatively and in assembled relationship support the green cast product substantially throughout its lower surface, and one of said parts supporting a cast product throughout only a portion of its lower surface when said parts are separated and in a disassembled relationship, said one part being adapted for transport of the cast product after curing and when it has attained substantially its full strength, and said one part of each base section being supported vertically by the other part thereof and free to move upwardly relative thereto, and access opening being provided beneath each of said parts for selective lifting thereof, said other part serving to raise said one part simultaneously when it is lifted itself.
