Compactly-shipped site-assembled concrete forms for producing variable-width insulated-sidewall fastener-receiving building walls

A building system serving as both a form for a wall made of poured construction material and a permanent surface to the wall once poured, the combination wall-forming and wall-surfacing system comprising:

• two substantially planar spaced-parallel construction forms each of rectangular configuration having and defining
• edges of a relatively longer length aligned horizontally, edges of a relatively shorter length aligned vertically,
• a respective inner surface directionally disposed to face a corresponding inner surface of the other, spaced-parallel, form and
• a planar outer surface directionally disposed away from the other, spaced-parallel, form, and
• a plurality of vertically-extending slots;
• a multiplicity of first metal pieces, each of which is sized and adapted so as to fit though a one of the plurality of slots of each of the two forms so as to extend from the form's outer surface to its inner surface, each first metal piece having and defining
• a flange located at the exterior surface of a form when the metal piece is inserted within a vertical slot of the form, that extends substantially parallel to the exterior surface of the form and transverse to the form's slot so as to both (i) preclude that the metal piece should be possible of being pulled through the form from its exterior to its interior surface, and (ii) present a metal surface that is suitable to attach and to retain a fastener, and
• an engagement feature, located at the interior surface of a form when the metal piece is inserted within a vertical slot of the form, that is suitably sized and configured so as to be passed through the slot of the form and so as to, when so inserted into a slot, extend beyond the interior surface of the form;
• and
• a plurality of variably preselected length second metal pieces, each of which is sized and adapted so as to engage two oppositely-disposed engagement features of two first metal pieces as are respectively inserted into two oppositely-disposed slots of two forms, each second metal piece having and defining
• two ends,
• a variably selectively predetermined lineal extent between the two ends, a measure of which extent will determine how far apart the first and the second form are spaced-parallel, and
• an engagement feature, complimentary to the engagement feature of each of the first pieces, at each end, each of which end engagement features is suitably sized and configured so as to engage, to retain, and to connect the engagement feature of a first metal piece as has been inserted through a form's slot and as extends beyond the form's interior surface;
• wherein when the two forms are held spaced parallel at variably preselected separation by the multiplicity of first metal pieces as extend through the plurality of slots of each form, and by the plurality of second metal pieces as engage and retain and connect the first metal pieces, then a poured construction material may be poured to fill a variable-width cavity that is defined between the two spaced parallel forms, the poured construction material capturing in its matrix parts of the first metal pieces and all of the second metal pieces, the poured construction material and creating a wall having the substantial thickness of two first metal pieces and the one preselected second metal piece of variable length and having the two forms as a facing to the wall upon each of its two sides;
• wherein regardless of the suitability of the forms to engage and to retain a fastener, at least the flange of each first metal piece, which flange is located at the exterior surface of a form when the metal piece is inserted within a vertical slot of the form, is so suitable to attach and to retain a fastener.

A method of constructing a wall of a building upon a level foundation from separate and modular components, the method comprising:

• placing a first course of paired opposed substantially planar rectangular forms in a spaced parallel relationship upon the foundation;
• inserting first metal pieces from an exterior surface of each form of each opposed pair through slots in each form to, and to extend beyond, an interior surface of the same form, therein to be positionally juxtaposed to a corresponding identical first metal piece lodged in the opposed spaced-parallel form;
• connecting with preselected second metal pieces of variable length the juxtaposed first metal pieces, therein locking in position the opposed spaced-parallel forms at a variably preselectably predetermined distance of separation;
• repeating the placing, the inserting and the connecting for successive courses of opposed spaced-parallel forms until a vertically standing array of spaced-parallel forms defining a cavity of variably preselected width is created;
• pouring a construction material into the cavity between the vertically arrayed spaced-parallel forms, therein to create a wall that consists of forms spaced-parallel at a variably preselectably predetermined distance of separation serving to sandwich a central core of poured building material;
• wherein, notably, the thickness of the wall was variably selectably predetermined during its construction by, most notably, preselection of the second metal pieces.
