Manufactured assembly and method for forming concrete foundations and walls

Abstract

A manufactured assembly and method used to form poured concrete foundations and walls. The foundation and wall form's lattice grid exterior face holds adequate flow though concrete, with the assistance of the exterior grid fingers, for smoothing and decorative treatments and troweling is aided by lattice grid exterior screed guide points. The lattice grid panels, the lattice grid forming panel flow through concrete and the form cavity poured concrete become a substantially monolithic structure when the concrete is set and hardens dry. Rigid foam insulation is added to the center of a lattice grid paneled poured concrete wall form.

CROSS-REFERENCED TO RELATED APPLICATIONS[0001]This application is a continuation-In-Part of application Ser. No. 12 / 198,973 filed Aug. 27, 2008.FIELD OF THE INVENTION[0002]This invention relates to the manufacturing assembly and method using flowing concrete or other cementous material to form poured concrete foundations and walls. This invention also relates to the concrete / cementous material flow through and accumulation on the lattice grid panel of a concrete form to create an adequate concrete layer on the external surface of the panel for effective smoothing and decorative finish. This invention further relates to insulated poured concrete walls.BACKGROUND OF THE INVENTION[0003]The process of constructing a poured concrete foundation and wall has conventionally required forms to be created on site, wherein the concrete forms may consist of wood, metal, plastic or wood / metal panels erected and maintained in spaced, parallel relationship with other panels. Fluid concrete is then ...

AI Technical Summary

Benefits of technology

[0011]A preferred embodiment of the foundation forming assembly comprises a first lattice framework panel having a plurality of openings throughout and a second lattice panel where the two panels are spaced apart in a parallel relationship. The two lattice panels are connected together and held spaced apart by a number of cross connecters. The forming assembly would usually have other spaced apart lattice panels connected end to end held spaced apart by a number of cross connection members and are placed on the construction surface that the base of the structure will be built. The footing form assembly is designed so that the concrete footing form assembly can be “stepped” up or down which allows vertical adjustment in horizontal surface changes of the surface being poured upon, such as a sloping building site.

[0019]A second advantage of being able to pour the two cavities in separate pouring with a center insulated rigid foam wall concrete form is that an adjacent slab floor can be poured with the first or second pouring of the cavities of the wall form. Usually the slab would be poured with the same pouring as the wall cavity that is the exterior cavity (other side of center insulated foam concrete form) from the poured slab and both are usually the second pouring so that the usually wider interior cavity would fill the foundation footing cavity more efficiently.

Problems solved by technology

Problems associated with these processes include higher labor costs, higher equipment costs, lack of uniformity, and expense associated with the removal and disposal of the forming panels.

Also the difficulty of adding insulation within the concrete forms and the ability to perform exterior decorative treatments while maintaining a durable concrete exterior surface has been problematic in these concrete forming processes.

The biggest disadvantage of a two-stage pour is that it is more expensive than a monopour.

The cost to crane lift the tilt-up slab wall in place is expensive and the architectural style and look of tilt-up structures is fairly limited due to the nearly flat repeated slab panel construction.
