Claim 3

The merging wall units as defined in claim 1 being particularly characterized in that at least one of said opposed outer sheets is secured to said ceiling slat with said wall unit being retained in raised disposition.

Claim 4

The merging wall units as defined in claim 1 being particularly characterized in that the bottom edge of said floor slat extends beyond the bottom edge of each of said opposed outer sheets.

Claim 5

The merging wall units as defined in claim 1 being particularly characterized in that the top edge surface of said ceiling slat is overlaid with an elastic sound-absorbing strip.

Claim 6

A procedure for the installation of a wall unit in a building structure to have finished floors and ceilings and wherein the wall unit consists of at least first and second prefabricated wall units, each unit having two opposed outer sheet surfaces separated by spacing members forming a frame and wherein the top and bottom edge surfaces of the wall units are provided with continuous ceiling grooves and floor channels respectively, said grooves and channels each being respectively arranged to accept a ceiling slat and a fixed floor slat of approximately corresponding rectangular cross-section, the floor slat being a part of said frame, and said ceiling slat being further arranged to be fastened to the room ceiling, wherein said wall units are characterized in that: a. each wall unit comprises a lateral remote vertical edge and a lateral proximal edge, a ceiling inner starter slat piece having a portion projecting over the remote edge of the wall unit within said ceiling groove, with the remaining portion of said ceiling groove being arranged to receive the ceiling slat of the said wall unit, with said proximal end of said ceiling slat having a projecting portion with a projecting wedge protrusion extending slopingly downwardly and over the lateral remote vertical edge of the adjacent wall unit to be subsequently installed for receiving a ceiling slat associated with said adjacent wall unit to be subsequently installed; b. each wall unit having a floor slat element therein, said floor slat element having a length less than the width of the wall unit to which it is attached, said floor slat element being disposed along a substantial portion of said wall and extending to said proximal vertical edge and cooperating with an extension segment extending longitudinally outwardly from said floor slat, the proximal end of said floor slat having a wedge surface extending slopingly upwardly, and the opposed end surface of said segment having a corresponding wedge surface extending slopingly downwardly, said extension segment being arranged for accepting the floor channel of an adjacent wall unit to be subsequently installed, and being further adapted to be disposed horizontally adjacent the complementary wedge surface of said floor slat for raising said first wall unit upwardly from the floor surface; said method comprising: 1. fastening a short ceiling starter slat piece and a floor extension segment to a room ceiling and floor respectively, with the ceiling slat piece segments each having a wedge protrusion thereon, forcing a wall unit with its ceiling groove and floor channel respectively over the starter ceiling slat piece wedge protrusion and floor extension segment respectively; 2. forcing the ceiling slat of the wall unit adjacent said protrusion until abutment is achieved with the ceiling, and securing the proximal end of said ceiling slat onto the ceiling surface, thereafter raising the unit to the point of contact of the opposed outer sheets with the ceiling and driving the floor extension segment having the wedge surface against the wedge surface of the floor slat; 3. fastening said floor extension segment to the floor; and 4. placing an additional wall unit in place starting from the then extending ceiling slat piece wedge protrusion and floor extension segment of the last-installed wall unit.

Claim 7

A procedure for the installation of a wall unit in a building structure to have finished floors and ceilings and wherein the wall unit consists of at least first and second prefabricated wall units, each unit having two opposed outer sheet surfaces separated by spacing members forming a frame and wherein the top and bottom edge surfaces of the wall units are provided with continuous ceiling grooves and floor channels respectively, said grooves and channels each being respectively arranged to accept a ceiling slat and a fixed floor slat of approximately corresponding rectangular cross-section, the floor slat being a part of said frame, and said ceiling slat being further arranged to be fastened to the room ceiling, wherein said wall units are characterized in that: a. each wall unit comprises a lateral remote vertical edge and a lateral proximal edge, a ceiling inner starter slat piece having a portion projecting over the remote edge of the wall unit within said ceiling groove, with the remaining portion of said ceiling groove being arranged to receive the ceiling slat of the said wall unit, with said proximal end of said ceiling slat having a projecting portion with a projecting wedge protrusion extending slopingly downwardly and over the lateral remote vertical edge of the adjacent wall unit to be subsequently installed for receiving a ceiling slat associated with said adjacent wall unit to be subsequently installed; b. each wall unit having a floor slat element therein, said floor slat element having a length less than the width of the wall unit to which it is attached, said floor slat element being disposed along a substantial portion of said wall and extending to said proximal vertical edge and cooperating with an extension segment extending longitudinally outwardly from said floor slat, the proximal end of said floor slat having a wedge surface extending slopingly upwardly, and the opposed end surface of said segment having a corresponding wedge surface extending slopingly downwardly, said extension segment being arranged for accepting the floor channel of an adjacent wall unit to be subsequently installed, and being further adapted to be disposed horizontally adjacent the complementary wedge surface of said floor slat for raising said first wall unit upwardly from the floor surface; said method comprising: 1. fastening a short ceiling starter slat piece and a floor extension segment to a room ceiling and floor respectively, with the ceiling slat piece segments each having a wedge protrusion thereon, forcing a wall unit with its ceiling groove and floor channel respectively over the starter ceiling slat piece wedge protrusion and floor extension segment respectively; 2. forcing the ceiling slat of the wall unit adjacent said protrusion until abutment is achieved with the ceiling, and securing the proximal end of said ceiling slat onto the ceiling surface, thereafter raising the unit to the point of contact of the opposed outer sheets with the ceiling and driving the floor extension segment having the wedge surface against the wedge surface of the floor slat; 3. fastening said floor extension segment to the floor; and 4. placing an additional wall unit in place starting from the then extending ceiling slat piece wedge protrusion and floor extension segment of the last-installed wall unit.
