Abstract
Abstract A prefabricated wall system employing laminar wall panels formed from an expanded high density polystyrene core bonded to two outer skins, the panels being mounted on tracks provided by a longitudinally extending base rail which has hollow electrical ducts therein. Removable cover plates carrying electrical service outlets conceal the base rail ducts, and a hollow trim member is removably secured to a panel to carry wiring vertically from the base rail.

Independent Claim
28 words
The system of claim 1 wherein the base rail has two upwardly extending mounting tracks thereon, and the panel member has two slots for mating with the tracks.
Claim 2
Dependent Claim
14 words
The system of claim 1 wherein the base rail has substantially an ''''I'''' cross-section.
Claim 3
Dependent Claim
23 words
The system of claim 3 including a second cover plate for concealing the second hollow portion formed by the ''''I'''' cross-section base rail.
Claim 4
Dependent Claim
22 words
The system of claim 3, wherein the upper flange of the base rail is at least as wide as the panel member.
Claim 5
Dependent Claim
29 words
The system of claim 1 further including a trim anchor adapted to being secured to an edge of the panel member and adapted to engagement with the trim member.
Claim 6
Dependent Claim
86 words
A prefabricated wall system comprising: a base rail having at least one longitudinally extending hollow duct therein; at least one panel member positioned on the base rail; at least one cover plate carrying electrical service outlets removably secured to the base rail for concealing the hollow duct, the cover plate having a lip extending downwardly below the base rail; and a trim member removably secured to the panel to form a concealed hollow channel adjacent at one end thereof to the duct in the base rail.
Claim 7
Dependent Claim
54 words
A prefabricated wall system comprising: a base rail having a longitudinally extending hollow duct therein; a panel member supported by the base rail; a trim member carrying a light switch and removably secured to the panel to form a concealed channel communicating at one end thereof with the hollow duct of the base rail.
Claim 8
Dependent Claim
58 words
An electrical duct-base rail system for a wall employing a finished wall panel to be placed thereon comprising: an I-beam having its upper flange at least as wide as the panel; and at least one cover plate removably secured across an open side of the I-beam and having an extended width such that it extends below the I-beam.
Claim 9
Dependent Claim
58 words
A prefabricated wall system comprising: a base rail having an electrical duct therein and having two upstanding mounting tracks; a laminar panel member mounted on the base rail and having a foamed plastic core between two outer skins, the core being provided with a pair of spaced slots at the lower edge thereof to receive the mounting tracks.
Claim 10
Dependent Claim
57 words
The system of claim 16 wherein the base rail is an I-beam having its upper flange at least as wide as the panel and further including a cover plate adaptable to being removably secured across an open side of the I-beam and having an extended width such that when so installed it extends substantially below the I-beam.
Claim 11
Dependent Claim
61 words
A prefabricated wall system comprising: an I-beam base rail having a series of spaced holes in the top flange thereof for receiving a cartridge nail set gun during installation; a panel member supported by the base rail; and a removable cover plate on the the base rail carrying electrical service outlets and concealing the duct formed in the I-beam base rail.
