Abstract

Form apparatus for casting concrete. It includes a platform having a work-supporting upper face, and plural, hollow box-like tub molds distributed over the platform. Each mold has a perimeter flange adjacent its base and projecting outwards from the sides of the mold. A lattice frame paralleling and supported by the platform contains plural openings, and each opening snugly receives bottom margins of the sides of a mold. The lattice frame positions the molds on the platform with the perimeter flanges of the molds disposed between the lattice frame and the platform. A knockdown encompassing frame with sides extends upwardly from adjacent the periphery of the lattice frame forming a concrete-leakage inhibiting seal between the sides and the lattice frame. The apparatus provides portable apparatus for casting a multi-niche columbarium module close to a burial site.

Claims

1. Apparatus for casting concrete comprising

a platform element adapted to be supported on the ground having a work-supporting essential non-perforate upper face,

plural box-like molds each having a top, sides and a base, said molds being distributed over said platform element with their bases facing against said upper face of said platform element,

a lattice frame paralleling and supported by the platform element comprising a planar element with plural openings extending therethrough, each opening snugly receiving bottom margins of the sides of a mold, said lattice frame further positioning said molds on the platform element, each mold comprising a tub mold having a perimeter flange adjacent its base integral with the sides of the mold and projecting outwardly from the mold sides, said flange disposed between the lattice frame and the platform element, and

a knockdown encompassing frame with sides extending upwardly from adjacent the periphery of said lattice frame, said encompassing frame overlying said lattice frame around the periphery of the lattice frame, and clamps securing the encompassing frame, the lattice frame, and the platform element together, thereby establishing a concrete-leakage inhibiting seal between said lattice frame and the encompassing frame and between the base of the tub molds and the lattice frame.

2. The apparatus of claim 1, wherein said encompassing frame is positioned on the lattice frame with pins interconnecting the two.

3. Apparatus for casting concrete comprising

a platform having a work-supporting upper face,

plural molds each having a top, sides and a base and a perimeter flange adjacent said base integral with said sides and projecting outwardly from said sides, said molds being distributed over said platform with their bases facing against said platform,

a lattice frame paralleling and supported by the platform comprising a planar element with plural openings extending therethrough, each opening snugly receiving bottom margins of the sides of a mold and said lattice frame resting on the perimeter flanges of said molds, said lattice frame further positioning said molds on the platform, wherein said lattice frame includes multiple elongate expanses, paralleling and laterally spaced from each other extending in one direction in the frame, and a second set of multiple elongate expanses paralleling and laterally spaced from each other extending transversely of said first set and joined therewith, said expanses forming a flush surface on the upper side of said lattice frame, said sets of expanses forming said openings in said frame, wherein certain of said expanses have bores extending therethrough,

anchor members having internally threaded bores positioned against said expanses with said anchor members extending upwardly from said upper side of the frame,

detachable fasteners projecting through said bores in the expanses and screwed into the threaded bores of the anchor members holding the anchor members in place, and

a knockdown encompassing frame with sides extending upwardly from adjacent the periphery of said lattice frame, said encompassing frame overlying said lattice frame around the periphery of the lattice frame, and clamps securing the encompassing frame, the lattice frame, and the platform together, thereby establishing a concrete-leakage inhibiting seal between said lattice frame and the encompassing frame and between the base of the tub molds and the lattice frame.

4. The apparatus of claim 7, wherein said molds are generally hollow box-like tub molds, each having an open base and otherwise substantially closed, each tub mold having a perimeter flange adjacent its base integral with the sides of the mold and projecting outwards from the sides and disposed between the lattice frame and the platform.

5. Apparatus for casing concrete comprising

a platform element adapted to be supported on the ground having a work-supporting upper face,

plural hollow box-like tub molds each having a top, sides and a base, said molds being distributed over said platform element with their bases facing against said upper face of said platform element, each mold having a open base and otherwise being substantially closed, each mold having a perimeter flange adjacent its base integral with the sides of the mold and projecting outwards from the sides,

a lattice frame paralleling and supported by the platform element comprising a planar element with plural openings extending therethrough, each opening snugly receiving bottom margins of the sides of the mold and said lattice frame resting on the perimeter flanges of said molds, said lattice frame further positioning said molds on the platform element, and

a knockdown encompassing frame with sides extending upwardly from adjacent the periphery of said lattice frame and clamps securing the encompassing frame through the lattice frame to the platform element with a concrete-leakage inhibiting seal established between the lattice frame and the encompassing frame and between the base of the tub molds and the lattice frame.
