US 5,511,761 A · Apparatus and method for forming monolithic footings and foundation

Abstract

A wall forming apparatus for constructing monolithic concrete footings and walls of a building foundation which includes a plurality of relatively light-weight prefabricated wall forming panels connected together and positioned to form a plurality of opposing monolithic footing and wall forming units, each panel having an outer rigid framework from which an adjustable footing form depends, the opposing footing forms of the opposing footing and wall forming units being devoid of any structure extending directly therebetween, and the framework of each panel being constructed of sufficient rigidity and with sufficient cross-sectional dimensions so as to prevent canting and sagging of the footing and wall forming units formed by the panels when interconnected. Construction and proper placement of the integral footing and wall forming units is accomplished by placing the panels side-by-side on a flat surface and rigidly interconnecting the same at the adjacent upper and lower corners thereof, and thereafter hoisting each constructed footing and wall forming unit into desired position through the use of a crane or other suitable hoisting device.

Dependent claims

A wall forming apparatus for constructing monolithic concrete walls and footings, comprising:

(a) at least one pair of rigid wall forming panels being spaced apart and oppositely disposed relative to one another, each of said wall forming panels having elongated top, bottom and side peripheral frame portions, an inner planar concrete forming surface and an opposing outer surface;
(b) each of said opposing wall forming panels having an elongated rigid footing forming member depending from said bottom peripheral frame portion thereof, thereby defining at least one pair of spaced opposing integral footing and wall forming units with a coextensive concrete receiving cavity therebetween for forming a monolithic concrete footing and wall;
(c) means for adjustably connecting each said footing forming member to said wall forming panel from which it depends to vary the position of said footing forming member relative to said wall forming panel from which it depends;
(d) tieing means disposed above said footing forming members and extending between said opposing wall forming panels for maintaining said opposing footing and wall forming units in desired spaced relation during the pouring of concrete within said concrete receiving cavity;
and
(e) said concrete receiving cavity being devoid of any structure extending within the confines thereof below said bottom peripheral frame portion of said wall forming panels.

A wall forming apparatus for constructing monolithic concrete walls and footings, comprising:

(a) at least one pair of rigid wall forming panels being spaced apart and oppositely disposed relative to one another, each of said wall forming panels having elongated top, bottom and side peripheral frame portions, a separate inner planar concrete forming surface attached to said frame portions, and an opposing outer surface;
(b) each of said opposing wall forming panels having an elongated rigid footing forming member depending from said bottom peripheral frame portion thereof, thereby defining at least one pair of spaced opposing integral footing and wall forming units with a coextensive concrete receiving cavity therebetween for forming a monolithic concrete footing and wall;
(c) means for positively connecting each of said footing forming members to said wall forming panel from which it depends;
(d) tieing means disposed above said footing forming members and extending between said opposing wall forming panels for maintaining said opposing footing and wall forming units in desired spaced relation during the pouring of concrete within said concrete receiving cavity;
and
(e) each of said opposing footing and wall forming units being independently prefabricated as separate integral one-piece portable units and constructed to be free of interconnecting structure extending directly between said opposing footing forming members to facilitate free release of said footing and wall forming units as independent integral one piece units upon release of said tieing means after proper hardening of the monolithic concrete wall and footing formed thereby.
