Prefabricated structures for use in electrical wiring

Claim 2

A building wall structure comprising: a. a wall frame providing an internal vertical face to which a sheet member is applied to close the frame and provide a corresponding internal wall surface; b. the wall frame being constituted by a horizontal sole member, a spaced parallel horizontal head member, and parallel vertical stud members extending between and connecting the head and sole members; c. a channel member having a C cross-section and mounted within the said wall frame; d. the channel member having the lower leg thereof fastened to the sole member and the open face of the channel opening to the said internal vertical face of the wall frame; e. the said sheet member applied to the said wall frame internal vertical face also closing the open face of the channel so that the channel and the adjacent portion of the panel member constitute a closed raceway for electric wiring; f. wherein the raceway channels of two wall structures abutting at right angles to one another terminate short of the respective abutting edges of the wall structures; g. there is provided a bridging member for conveying electrical wiring between the two raceway channels comprising an upwardly-opening channel extending between the two wall structues at approximately 45° to each structure; and h. wherein the bridging channel member is supported in the structure by a triangular support member fastened to the bridging channel member and to both wall structures, the support member receiving and supporting a cover plate for closing the bridging channel member.

Claim 3

A building wall structue comprising: a. two vertically-superimposed walls each having an inner and an outer face; b. a deck member having at an edge thereof a horizontal flange interposed between the two walls and two spaced vertical flanges connected to the horizontal flange, the two vertical flanges being disposed on opposite sides of the upper of the two vertically superimposed walls and extending vertically upwards alongside respectively the inner and outer faces thereof; c. each wall comprising a wall frame providing an internal vertical face to which a sheet member is applied to close the frame and provide a corresponding internal wall surface; d. the wall frame being constituted by a horizontal sole member, a spaced parallel horizontal head member, and parallel vertical stud members extending between and connecting the head and sole members; e. a channel member having a C cross-section and mounted within the said wall frame; f. the channel member having the lower leg thereof fastened to the sole member and the open face of the channel opening to the said internal vertical face of the wall frame; g. the said sheet member applied to the said wall frame internal vertical face having its lower edge interposed beteen the vertically-upwardly-extending flange that extends alongside the inner wall face and the adjacent part of the wall frame internal vertical face, the sheet member also closing the open face of the channel so that the channel and the adjacent portion of the panel member constitute a closed raceway for electric wiring; and h. the last-mentioned vertical flange being of sufficient depth to overlap the open face of the channel member.

Claim 4

A building wall structue comprising: a. two vertically-superimposed walls each having an inner and an outer face; b. a deck member having at an edge thereof a horizontal flange interposed between the two walls and two spaced vertical flanges connected to the horizontal flange, the two vertical flanges being disposed on opposite sides of the upper of the two vertically superimposed walls and extending vertically upwards alongside respectively the inner and outer faces thereof; c. each wall comprising a wall frame providing an internal vertical face to which a sheet member is applied to close the frame and provide a corresponding internal wall surface; d. the wall frame being constituted by a horizontal sole member, a spaced parallel horizontal head member, and parallel vertical stud members extending between and connecting the head and sole members; e. a channel member having a C cross-section and mounted within the said wall frame; f. the channel member having the lower leg thereof fastened to the sole member and the open face of the channel opening to the said internal vertical face of the wall frame; g. the said sheet member applied to the said wall frame internal vertical face having its lower edge interposed beteen the vertically-upwardly-extending flange that extends alongside the inner wall face and the adjacent part of the wall frame internal vertical face, the sheet member also closing the open face of the channel so that the channel and the adjacent portion of the panel member constitute a closed raceway for electric wiring; and h. the last-mentioned vertical flange being of sufficient depth to overlap the open face of the channel member.
