Abstract

Abstract A unitary building wall, having a plurality of sets of passageways disposed therein and serving as a conduit for introducing the necessary utilities to a dwelling unit, is disclosed. A plurality of sets of tree-like passageways, which passageways include a trunk and one or more tributaries, are disposed within an otherwise solid building wall. The trunks of the passageways extend into and out of the building wall and communicate with similar trunks disposed in adjacent vertically aligned walls. A plurality of orifices are disposed in the lateral side of the building wall and communicate with one of the trunk or tributaries of one of the sets of passageways. The various fixtures within a dwelling unit, such as a tub, toilet, sink and lights, are connected to the orifices. Thereby, the fixtures are connected to the various utilities disposed within one or another of the sets of passageways. A method is also disclosed for forming the unitary building wall, which method includes the construction of a plurality of disposable or hollow trees, each tree defining one set of passageways. The trees are positioned within a form, which form defines the exterior dimensions of the building wall. A flowable hardenable material is poured within the form and allowed to set and cure. After curing, the trees, if made of ice and therefore disposable, are melted and will leave tree-like passageways within the building wall. If the trees are not disposable but hollow, they form a plurality of tree-like passageways within the building wall.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 292 words
Apparatus for conveying utilities to and from utility inlets and outlets of fixtures within a dwelling unit, said apparatus comprising: a. a unitary wall member defining a boundary of the dwelling unit: b. said unitary wall member including a chase disposed along one vertical side of said unitary wall member, said chase being adapted to receive a plurality of conduits serving as a source for the water and electrical utilities supplied to the dwelling unit; c. a first plurality of passageways extending into said unitary wall member from said chase and out of said unitary wall member through an orifice in at least one lateral side of said unitary wall member, said first plurality of passageways conveying a utility to said unitary wall member; d. a second plurality of passageways extending into and out of said unitary wall member from opposed horizontal sides of said unitary wall member, each of said second plurality of passageways including at least one orifice disposed in one face of said unitary wall member for receiving exhaust products from within the dwelling unit; e. pipe means disposed within said chase for interconnecting the source of utilities with respective ones of said first plurality of passageways; f. further pipe means secured within each of the orifices in each lateral side of said unitary wall member for interconnecting said first and second plurality of passageways with the respective inlets and outlets of the fixtures; and g. each of said first and second plurality of passageways being essentially devoid of pipe means for channeling the utilities and exhaust products, respectively; whereby, utilities are conveyed into the dwelling unit through said first plurality of passageways and exhaust products are conveyed out of the dwelling unit through said second plurality of passageways.
Claim 2
Dependent Claim 292 words
Apparatus for conveying utilities to and from utility inlets and outlets of fixtures within a dwelling unit, said apparatus comprising: a. a unitary wall member defining a boundary of the dwelling unit: b. said unitary wall member including a chase disposed along one vertical side of said unitary wall member, said chase being adapted to receive a plurality of conduits serving as a source for the water and electrical utilities supplied to the dwelling unit; c. a first plurality of passageways extending into said unitary wall member from said chase and out of said unitary wall member through an orifice in at least one lateral side of said unitary wall member, said first plurality of passageways conveying a utility to said unitary wall member; d. a second plurality of passageways extending into and out of said unitary wall member from opposed horizontal sides of said unitary wall member, each of said second plurality of passageways including at least one orifice disposed in one face of said unitary wall member for receiving exhaust products from within the dwelling unit; e. pipe means disposed within said chase for interconnecting the source of utilities with respective ones of said first plurality of passageways; f. further pipe means secured within each of the orifices in each lateral side of said unitary wall member for interconnecting said first and second plurality of passageways with the respective inlets and outlets of the fixtures; and g. each of said first and second plurality of passageways being essentially devoid of pipe means for channeling the utilities and exhaust products, respectively; whereby, utilities are conveyed into the dwelling unit through said first plurality of passageways and exhaust products are conveyed out of the dwelling unit through said second plurality of passageways.
Claim 3
Dependent Claim 39 words
The apparatus as set forth in claim 1 wherein each said second plurality of passageways includes a trunk extending from the top horizontal side of said unitary wall member to the bottom horizontal side of said unitary wall member.
Claim 4
Dependent Claim 82 words
The apparatus as set forth in claim 2 wherein said unitary wall member includes a female compression fitting disposed in the top horizontal side of said unitary wall member and communicating with said trunk and a male compression fitting extending from the bottom horizontal side of said unitary wall member and communicating with said trunk; whereby, a plurality of said unitary wall members may be stacked on top of one another while retaining a contiNuous vertical cavity through said stacked wall members.
Claim 5
Dependent Claim 47 words
The apparatus as set forth in claim 1 wherein said second plurality of passageways includes a first set of passageways for waste disposal, a second set of passageways for venting said first set of passageways, and a third set of passageways for heat, ventilation and air conditioning.
Claim 6
Dependent Claim 40 words
The apparatus as set forth in claim 4 wherein said first plurality of passageways includes a fourth set of passageways for hot water, a fifth set of passageways for cold water and a sixth set of passageways for electrical power.
