Free-standing form for building a pre-insulated wall

摘要

A free-standing, hollow, prefabricated concrete form for forming a lost form, pre-finished concrete wall having an insulating layer on at least one major surface, typically an outer, earth facing surface thereof. The inside of the form has a rough finished surface. The form provides metal studs, typically on conventional sixteen inch centers, thereby enhancing the strength of the wall. The form allows placement of conduits for wiring, either electrical power or so-called low voltage circuits (e.g., telephone, TV cable, network wiring, audio cables, etc.) within the wall. Water supply and drain lines may also be placed within the wall prior to filling the forms with concrete. Multiple prefabricated sections may be joined to one another end-to-end to fabricate longer walls.

主权项

1. A free-standing, hollow form for a lost form, concrete-filled wall, comprising:
a) a bottom and a top framework each having a length and a width, said length being greater than said width and defining a major axis therealong, said width being perpendicular to said major axis and defining a minor axis therealong, elements of said top framework and said bottom framework comprising two parallel, spaced-apart long pieces of angle stock defining said length connected to shorter pieces of angle stock defining said width, said long pieces of said angle stock and said shorter pieces of angle stock being disposed normally to one another; b) a plurality of studs having a predetermined length and being disposed between and attached to said bottom framework and to said top framework, said plurality of studs being disposed in a perpendicular relationship to said major axis of each of said top framework and said bottom framework, said studs being disposed along both a front edge and a rear edge of both of said bottom framework and said top framework, said studs being spaced apart from one another by a predetermined distance; c) a plurality of spacers having uniform, planar upper and lower surfaces and a predetermined length and being disposed between said studs, each of said plurality of spacers being disposed at any one of an infinite number of positions along the length t of said studs, said spacers being disposed along said front edge of both said top framework and said bottom framework and a corresponding stud placed along an opposite one of said front edge and said rear edge of both said top framework and said bottom framework, said plurality of spacers each being parallel to said minor axis; d) at least one reinforcing bar connected to each of said plurality of front edge spacers, each of said plurality front edge spacers being disposed at any at any one of an infinite number of positions along said length of said studs and extending perpendicular to said front edge spacers and connected to each of said corresponding plurality of rear edge spacers, respectively, for providing stability and reinforcement of said hollow form; and e) a planar material attached to a front face and a rear face of said free-standing hollow form, said front face and said rear face thereof each being defined by respective outfacing surfaces of said plurality of studs, a major plane of said planar material being parallel to said major axis.
