AI Technical Summary

Problems solved by technology

In cold, winter months, soil is prone to freezing.
Greater heat losses result in higher winter heating costs for homeowners.
A concrete foundation poured using this form would not include insulation on the bottom surface of the perimeter and would suffer from greater heat losses, compared to a form system that includes bottom insulation.
A form system made of concrete is much heavier and difficult to transport to and install at a job site.

example 1

[0036]A slab on grade foundation was poured using the form 1 and bracket assembly 8. FIG. 11 shows the ground 35 at the job site was first leveled with earth moving equipment to be approximately the shape of the building that would subsequently be constructed on the foundation. Earth moving equipment may include a payloader, a skid steer loader, or the like. The perimeter of the leveled ground was excavated to create a trench that was slightly larger than the foam form 1. The trench was approximately four (4) feet wide and one and a half (1.5) feet deep. Two to four inches of pea gravel 36 was placed in the bottom of the trench to provide a level surface for placing the forms 1 on top of. Alternatively, one to twelve inches of pea gravel may be used. Using pea gravel is advantageous in that it provides a level surface for the form 1 to rest on and requires less labor, compared to leveling the dirt under the forms. The area between the vertical inner wall 2 and the ground 35 was fill...

Abstract

A shallow foundation form and method of using are provided. The form is useful for pouring concrete slab foundations and results in a frost protected foundation with improved thermal characteristics. The form may include brackets to hold rebar at various locations. The brackets are designed to avoid the use of fastening devices, such as wire ties. When used to pour a concrete foundation, the form and brackets reduce construction material input costs, reduce the amount of skilled labor required, and reduce the amount of time required to pour a foundation.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 544,854 filed Aug. 13, 2017. The U.S. Provisional Application No. 62 / 544,854 is incorporated herein by reference in its entirety.FIELD[0002]The subject disclosure relates to shallow, frost protected foundations and their use in pouring concrete foundations.BACKGROUND OF THE INVENTION[0003]The present invention relates to a system for constructing frost protected, concrete slab foundations. The system reduces labor and material inputs and results in a frost protected, concrete foundation that transfers minimal heat from the concrete slab to the surrounding earth.[0004]In cold, winter months, soil is prone to freezing. The boundary line between frozen soil and unfrozen soil is referred to as the frost line. The frost line can be as deep as five feet below the surface of the ground in cold climates, such as northern Minnesota.[0005]Historically, deep footings have bee...
