  • Unitary form for poured foundation pad and method
    Patent number: 8919728
    Abstract: A unitary assembly facilitates constructing concrete foundation pads made of poured concrete, the foundation pads being useful to support a structure or building. The apparatus comprises a unitary assembly of existing planar forms connected by taper-shaped corners using wedge connectors to define an upwardly-tapered cavity shaped to hold poured concrete until the concrete cures. The assembly is sufficiently rigid and the planar forms are held at an angle sufficient for the unitary assembly to self-release from the cured concrete without disassembly when lifted/moved vertically off of the cured concrete.
    Type: Grant
