Abstract
Abstract An architecturally finished concrete structure is a composite of a finished wallboard member, such as plasterboard, plywood, etc., to which is bonded a plurality of elongated hollow void creating devices, with said devices being embedded in a concrete structure that is adhered to said finished wallboard member. In the subject method, one side, or both sides, of the concrete form for casting-in-place the concrete structure is defined by a finished wallboard member to which is adhered a plurality of elongated hollow void creating devices. Concrete is poured in the space defined by the concrete form, and is cured so as to be in intimate contact with, and embed, the void creating devices, and the resulting concrete structure is architecturally finished by having one or both faces thereof formed of said wallboard member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
An architecturally finished concrete structure comprising the combination of: a finished wallboard member; a plurality of elongated hollow void creating devices, each of said devices being bonded to one side of the finished wallboard, each said void creating device including opposed pairs of projections that abut with projections extending from adjacent devices; and a concrete structure in intimate contact with both said void creating devices and said one side of said finished wallboard whereby said wallboard forms a finished surface of the resulting concrete structure, while the opposite side of said resulting concrete structure is a continuous slab of concrete.
Claim 2
Dependent Claim
100 words
An architecturally finished concrete structure comprising the combination of: a finished wallboard member; a plurality of elongated hollow void creating devices, each of said devices being bonded to one side of the finished wallboard, each said void creating device including opposed pairs of projections that abut with projections extending from adjacent devices; and a concrete structure in intimate contact with both said void creating devices and said one side of said finished wallboard whereby said wallboard forms a finished surface of the resulting concrete structure, while the opposite side of said resulting concrete structure is a continuous slab of concrete.
Claim 3
Dependent Claim
21 words
An architecturally finished concrete structure as in claim 1 wherein the ends of said elongated hollow void creating devices are exposed.
Claim 4
Dependent Claim
15 words
An architecturally finished concrete structure as in claim 1 wherein said wallboard comprises plaster board.
Claim 5
Dependent Claim
16 words
An architecturally finished concrete structure as in claim 1 wherein said finished wallboard comprises wooden material.
Claim 6
Dependent Claim
29 words
An architecturally finished concrete structure as in claim 1 wherein said structure is a horizontal ceiling and wherein said finished wallboard is on the lower surface of said ceiling.
Claim 7
Dependent Claim
26 words
An architecturally finished concrete structure as in claim 1 wherein a second finished wallboard member is provided and forms the opposed surface of said concrete structure.
Claim 8
Independent Claim
151 words
A method for making a cast-in-place architecturally finished concrete structure comprising the steps of: bonding a plurality of elongated hollow void creating devices to a finished wallboard member, each said void creating device including opposed pairs of projections that abut with projections extending from adjacent devices; forming a planar concrete form to define the periphery of the concrete structure, at least one side of which planar form is the finished wallboard member, and with said void creating devices being disposed within said planar concrete form; forming a concrete structure by pouring uncured concrete into the spaces defined by said planar concrete form thereby embedding the void creating devices therein such that the uncured concrete is in intimate contact with both said void creating devices and with said finished wallboard; and removing said planar concrete form except for said wallboard member which is an integral part of said architecturally finished concrete structure.
Claim 9
Independent Claim
151 words
A method for making a cast-in-place architecturally finished concrete structure comprising the steps of: bonding a plurality of elongated hollow void creating devices to a finished wallboard member, each said void creating device including opposed pairs of projections that abut with projections extending from adjacent devices; forming a planar concrete form to define the periphery of the concrete structure, at least one side of which planar form is the finished wallboard member, and with said void creating devices being disposed within said planar concrete form; forming a concrete structure by pouring uncured concrete into the spaces defined by said planar concrete form thereby embedding the void creating devices therein such that the uncured concrete is in intimate contact with both said void creating devices and with said finished wallboard; and removing said planar concrete form except for said wallboard member which is an integral part of said architecturally finished concrete structure.
Claim 10
Dependent Claim
79 words
A method for making a cast-in-place architecturally finished concrete structure as in claim 7 wherein said concrete structure is a vertical wall member, and wherein the step of forming the planar concrete form comprises supporting said wallboard member in a generally vertical disposition, and shoring said member by reinforcing means, and providing a vertical form member spaced from and parallel to said wallboard member, with said void creating devices being disposed between said wallboard member and said form member.
Claim 11
Dependent Claim
40 words
A method for making a cast-in-place architecturally finished concrete structure as in claim 7 wherein the step of forming a planar concrete form comprises spacing two finished wallboard members in generally vertical disposition, and shoring said members by reinforcing means.
