1 Claim. (Cl. 52-241) The present invention relates to partitions and more particularly non-load bearing partitions employed between the concrete floors and ceilings of buildings.

Heretofore, in constructions of this type the plastered partitions have been snugly interposed between the floor and ceiling with the result that with bending movements of the building due to atmospheric conditions or the winds considerable cracking occurs.

It is an object of the present invention to provide a novel form of core board track arranged in opposed relationship respectively upon and along the floor and ceiling and secured thereto for supportably mounting and receiving non-load bearing partitions and primarily for the prevention of cracking in the plastered wall partitions.

It is another object to provide a wall partition or plastered core board assembly wherein there is a resilient relationship between the partition and the concrete floor and ceiling to accommodate for relative slight shifting movement of the building and for the prevention of cracking in the plastered core wall boards or other partition construction.

These and other objects will be seen from the following specification and claim in conjunction with the appended drawing in which:

FIG. 1 is a fragmentary vertical section of the present plastered partition interposed between a concrete floor and ceiling.

FIG. 2 is a fragmentary plan section taken on line 22 of FIG. 1.

FIG. 3 is similar to FIG. 1 illustrating a slightly different form of plastered partition.

FIG. 4 is a fragmentary plan section taken on line 4-4 of FIG. 3.

FIG. 5 is a fragmentary plan section taken on line 5-5 of FIG. 3.

FIG. 6 is a perspective view of the channel securing clips shown in FIG. 3. s

It will be understood that the above drawing illustrates merely a preferred embodiment of the invention, and that other embodiments are contemplated within the scope of the claim hereafter set forth.

Referring to FIGS. 1 and 2, the present non-load hearing wall partition is interposed between a concrete floor and ceiling of a building, the floor line being designated at 11, the finished ceiling line at 12 and the partition generally shown at 13.

An elongated floor track 14 is positioned upon and extends along the floor and is secured thereto by a series of fasteners 15 and includes the pair of upright spaced flanges and 22 which terminate in out-turned ends 21.

The elongated ceiling track 14 being of the same construction as the floor track, is arranged upon and extends along the ceiling and is secured thereto by fasteners 15. The ceiling track is arranged directly above the floor track and also includes depending flanges 20 and 22 terminating in out-turned ends 21. Flanges 22 are shorter than the flanges 20 to provide an entrant opening to facilitate assembly of core boards between the ceiling and floor tracks.

Core board track The ceiling and floor tracks 14, FIG. 1, each include the base flange 16 which at its opposite sides terminates in the upwardly and inwardly extending screed line flanges 17, the metal being reverse folded as at 18, and terminating in the horizontally disposed portions 19 which terminate in the upturned spaced flanges 20 and 22.

An elongated flexible and resilient gasket 23, preferably of rubber, plastic, neoprene or other resilient material is interposed between the ceiling 12 and ceiling track 14 and secured by track fasteners 15.

Partition Referring to FIG. 1, a suitable filler of wood, for illustration, in the form of a strip 24 is nested within the floor track between flanges 20 and 22 and serves as asupport for the longitudinally disposed upright coplanar core boards 25. These are interposed and supported between tracks 14 with their respective top and bottom edges nested between the respective pairs of flanges 2022. In assembly, the upper edges of core boards 25 are projected between the upper track flanges 2022, FIG. 1, until the bottom edges clear lower flange 22. The assembly is completed with the core boards resting upon filler 24, between floor track flanges 20, 22. This provides a dead air space 26 within the top track and above the core board so that at no time regardless of relative slight movements of the floor and ceiling is the core board under any form of compression or tension.

The individual core boards 25 are generally available on the market and are usually of a construction known as gypsum board, being solid gypsum or a composition having outer paper coverings 28.

As shown in FIG. 2, normally one edge of an upright core board 25 has an elongated groove of V-shape for illustration and the corresponding edge of the adjacent core board has a flange 29 of V-shape which interlocks or fits within the groove in a cooperative relation as shown in FIG. 2. The core boards may be placed side by side in flat edge to edge relationship if desired.

As a final step in the construction of the partition, thick plaster wall layers 30 and 31 are applied to and bear upon opposite sides of core board 25 and extend between and fill the space between the screed line flanges 17-18 of the floor and ceiling tracks. Each plaster wall layer has an exterior flat surface which is coplanar with the outer edge portions 32 of the screed line flanges 17- 13, FIG. 1.

Whereas, FIGS. 1 and 2 are directed to a non-cracking plaster core board partition, a slight variation is shown in FIG. 3 wherein there is a non-cracking solid plaster partition.

Solid plaster partition Referrings to FIGS. 3, 4, and 5, the solid plaster partition 34 employs the basic tracks 14 and 15 arranged in vertical registry respectively secured at 15 to the concrete or cement floor and ceilings 11 and 12 with the flexible yielding gasket 23 interposed.

Instead of core boards 25, FIG. 1, interposed between the respective vertically aligned opposed tracks 14, there are a series of upright longitudinally spaced coplanar metallic channels 35. These are interposed and supported between said tracks with their respective top and bottom edges nested and retained between the pairs of flanges 20, 22. The channels, in the illustrative embodiment, are arranged at center distances of 16 or 24 inches and extend across the partition area.

The channels are secured in the upright position shown by a series of spring clips 36 which extend around the channels, FIGS. 3 and 5 and whose revers curved retaining end portions 37 interlock with portions of track flanges 20, to maintain their upright positioning and for securing the channels 35 relative to the floor and ceiling tracks.

Upright longitudinally disposed metal lath 38 is interposed and supported between tracks 14 with corresponding top and bottom edge portions of the lath nested between flanges 20, 22 and adjacent flange 22. The lath is secured to the respective channels as by a series of wire fasteners 39, FIG. 4.

As a final step a solid and thick plaster wall layer is applied to the metal lath extending therethrough and upon opposite sides of the lathing as at 40 and 41 and thus fills the space between the screed line flanges 17-18. Wall element 4041 has exterior upright outer flat surfaces which are coplanar with the outer edge portions of the screed line flanges, as at 32.

In both constructions, FIGS. 1 and 3, the plaster wall portions 30-31, 40-41 do not extend snugly between the floor and ceiling lines, but only extend to and between the screed line flanges 17-18 of the respective tracks 14. Thus, the open areas 33 are provided between the upper edge portions of the plater walls and ceiling. Also, there are corresponding spaces 33 at the lower portions of the walls.

By this construction all cracking of the plastered walls is precluded in the event. that there is some shifting or bending movement of the respective floors and ceilings particularly characteristic of the larger buildings employing poured and solid concrete or cement walls and ceilings.

Having described our invention, reference should now be had to the following claim.

We claim:

An improved partition wall construction for use between the floor and ceilings of a building, comprising:

an elongated floor track extending along and attached to the floor, said floor track being generally channel shaped with a pair of upwardly extending spaced flanges, and a pair of screed line flanges extending outwardly beyond said spaced flanges along the floor on opposite sides of said track and terminating in upwardly inclined edges;

an elongated ceiling track extending along and resiliently attached to the ceiling through an interposed elongated resilient gasket, said ceiling track being generally channel shaped with a pair of downwardly extending spaced flanges and a pair of screed line flanges extending outwardly beyond said space flanges along the ceiling on opposite sides of said track and terminating in downwardly inclined edges;

vertical rigid wall supporting means having its upper and lower edges nested between and retained by said spaced flanges of said ceiling and floor tracks, respectively; and

a plaster wall coating applied to the opposite faces of said wall supporting means and extending upwardly and downwardly to said screed line flanges of said ceiling and floor tracks, respectively;

whereby the plaster portion of said wall is firmly but resiliently connected between the floor and ceiling and is spaced away from both'the floor and ceiling surfaces by said screed line flanges.
