Abstract
Footing forms border the bottom of an open space into which concrete may be poured. The forms are adjustable to various widths and lengths, and further provide support for commercially available foam wall forms that are used in concrete wall construction. The combination of adjustable footing forms with foam wall forms allows wall and footing to be poured together to form a monolithic concrete structure. The footing forms are adjustable to work in association with various standard and non-standard widths of foamed resin wall forms used in the building construction industry. The footing forms are fully removable from the concrete monolith, while leaving the foam wall forms with the cast concrete. Various corner components are also illustrated.

A static mold for casting a building footing and building wall monolithically from cementitious material using a removable footing form and a foamed resin wall form permanently retained as a part of said building wall and footing monolith in combination, said foamed resin wall form comprising:
- first and second major interior surfaces spaced apart from and facing each other between which said cementitious material is poured;
- first and second major exterior surfaces;
- a base having first and second minor surfaces;
- said footing form comprising:
- first and second footing mold walls, each having a first end, a base extending from said first end longitudinally to a second end along a first longitudinally extending edge, and a top spaced transversely from said base along a second longitudinally extending edge;
- a spacer separating said first and second footing mold walls from each other and thereby forming an open space therebetween for said cementitious material;
- a first support having a surface extending from said first footing mold wall towards said second footing mold wall and extending longitudinally along said first footing mold wall for vertically supporting said first minor surface of said foamed resin wall form, and having a first support spacer that maintains a gap between said first minor surface of said foamed resin wall form and said cementitious material that is larger adjacent said footing mold walls and smaller distal to said footing mold walls to facilitate separation of said footing form from said foamed resin wall form and said cementitious material;
- and
- a second support having a surface extending from said second footing mold wall towards said first footing mold wall and extending longitudinally along said second footing mold wall for vertically supporting said second minor surface of said foamed resin wall form, and having a second support spacer that maintains a gap between said first minor surface of said foamed resin wall form and said cementitious material that is larger adjacent said footing mold walls and smaller distal to said footing mold walls to facilitate separation of said footing form from said foamed resin wall form and said cementitious material;
- said foamed resin wall form further supported horizontally and transverse to said longitudinally extending edge by interaction between said first footing mold wall, said second footing mold wall and said first and second major exterior surfaces;
- said support separable from said cementitious material and said foamed resin wall form subsequent to a curing of said cementitious material without disrupting either said cementitious material or said foamed resin wall form.
A removable form for shaping a subterranean footing portion of a monolithic concrete footing and wall, wherein said wall is further characterized by a foam form for shaping said wall which remains permanently with said monolithic concrete, comprising:
- first and second longitudinally extensive walls for retaining concrete in a longitudinally extensive shape;
- a spacer for adjusting a first spacing between said first and second walls;
- and
- first and second supporting ledges each having a vertical support face and a horizontal support face, said vertical support face of said first supporting ledge extending from said first wall for vertically supporting said foam form, said vertical support face of said second supporting ledge extending from said second wall for vertically supporting said foam form, and said horizontal support faces each horizontally supporting said foam form and facing each other to form a horizontal space within which said foam form is located and retained horizontally, and further having first and second concrete forming surfaces extending beneath each of said first and second supporting ledge vertical support faces against which said monolithic concrete is formed;
- whereby said removable form is removable from said monolithic concrete and said foam form subsequent to a curing of said concrete without disrupting either said concrete or said foam form.
