G EORGE J. B YSSING ATTORNEY United States Patent 3,349,529 HOLLOW WALL PARTITION SYSTEM George J. Byssing, Los Angeles, Calif., assignor to Kaiser Gypsum Company, Inc., Oakland, Calif., a corporation of Washington Filed Mar. 15, 1965, Ser. No. 439,732 7 Claims. (Cl. 52-241) This invention relates to wall structures. More particularly it is concerned with a hollow demountable type wall structure wherein novel stud means are employed for assembling and anchoring groups of opposed and spaced wall board sections in place to form the said structure. This wall structure and the elements used therein also constitute improvements over those shown in my copending application S.N. 324,105, filed Nov. 15, 1963, now Patent No. 3,320,710.

Accordingly, it is a primary purpose of this invention to provide a novel hollow demountable type wall structure which has a unique stud element incorporated therein to which various wall board sections making up the opposed walls of the hollow wall structure are connected.

This and other purposes and advantages of the inst-ant invention will become more apparent from a review of the following detailed description when taken in con-V junction with the accompanying drawing, wherein:

'FIG. 1 is a cut away perspective view of an improved hollow wall structure incorporating the unique stud element of the instant invention;

FIG. 2 is a further enlarged fragmentary and perspective view of an improved wall structure incorporating the stud element of the instant invention and discloses one arrangement for removably attaching or aflixing the stud element to a floor runner;

FIG. 3 is a broken and fragmentary sectional view generally taken along the line 33 of FIG. 1 and With parts added;

FIG. 4 is a fragmentary sectional view generally taken along the line 44 of FIG. 1 with parts added; and

FIG. 5 is a fragmentary exploded view of a ceiling runner and an accessory trim strip which can be used therewith in assembling the wall structure of the invention.

With further reference to the drawings, and in particular FIG. 1, the hollow wall structure of the instant invention is generally comprised of a plurality or groups 1 of wallboard sections or units and a plurality of supporting stud elements 2. Each stud element 2 is channelshaped in cross-section such that it is provided with parallel side flanges 4 and a web portion 6. Struck out of and preferably formed integrally with the web portion 6 is one or more pairs of spaced tabs or flange elements 8. The length of these tab elements 8 is substantially less than the overall length of the web portion 6 and the stud element 2. When a plurality of flange elements or tabs 8 are used they are located in pairs at various spaced points along the length of the Web with the tabs in one pair being aligned with similar tabs in another or other pairs of tabs. Any number of such pairs of tabs 8 can be used depending upon the results desired.

Tabs 8 project from the web 6 in a direction which is diametrically opposite to the direction of projection of the side flanges 4. These flange elements 8 can be advantageously located inwardly of the outer surfaces 4a of the side flanges 4 of the stud 2 by a distance which approximates the thickness of an inner ply of a laminated wallboard unit that is affixed to the stud element in a manner to be described more fully hereinafter. This distance, for example, can be on the order of three-eighths of an inch. In a further advantageous embodiment of the invention, flange elements 8 can be provided with inward 1y directed and converging stiffening finger elements 9.

As indicated particularly in FIG. 2 a stud element 2 can be afiixed to a channel-shaped base or floor runner 10 by means of a channel-shaped fitting or shoe 11. The upper portion of this shoe 11 is adapted to be disposed within and frictionally engage the inner surfaces of the flange elements 8 of the stud with the finger elements 9 acting as shoe locking elements while the lower portion of the shoe 11 fits snugly within the channel-shaped floor runner 10 and engages the inner surfaces of the side elements or flanges 12 of the floor runner 10. It is to be understood of course that suitable anchoring elements (not shown) may also be used to lock the shoe 11 to the base runner 10 such as tabs struck out of the base runner and engageable with the web and/or flanges of the shoe 11.

The stud element can be of such a length whereby the bottom of the stud 2 rests on the tops of the sides 12 of the runner 10 with the lower portion of web 6 projecting outwardly from the sides 12 of the floor runner by a distance approximately equal to the thickness of the inner ply of a laminated wallboard unit which is to be anchored to and alfixed to the stud element 2.

The stud element 2 is adapted to anchor in place the individual wallboard units 14 in a first series of wallboard units on one side of the stud element 2 and to hold the wallboard units in this first series of wallboard units 14 in spaced relationship with respect to a similar series of wallboard units 14 on the opposing side of the stud element. Each of these wallboard units 14 can be made from a single piece of suitable wallboard material such as particle board, gypsum, plywood, etc. or as indicated in the drawings from a plurality of plies such as inner and

outer plies

15 and 16 of such materials. These individual plies are adhesively secured or otherwise tied together in an offset fashion so as to provide an overlap or shiplap portion 17 on the outer ply 16 at one side edge of the unit 14 and similar overlap portion 17a on the inner ply 15 at the other side edge of the unit 14. A rabbet groove or kerf 18, the purpose of which will be described more fully hereinafter, is also located in the wallboard unit 14 adjacent the terminal side edge of the inner ply 15 associated with the overlap 17 of the outer ply 16.

In assembling the wallboard units on one side of the stud element 2 or the wallboard units making up one series of units and with base runner 10 and a top runner 20, to be described more fully hereinafter, all in place, a first wallboard unit 14a as indicated in FIG. 1 is mounted upon a stud 2 in such a fashion that the groove or kerf 18 of unit 14a receives and accommodates one of the side flanges 4 of the stud. Thereafter, a second wallboard unit 1411 is mounted upon the same stud 2 in such a fashion that the shiplap portion 17a of unit 1415 is lodged or sandwiched between a tab 8 and shiplap portion 17 of the outer ply 16 of the unit 14a and with the inner surface x of the unit 14b engaging the outer surface y of the tab or flange element 8. At the same time the opposing free edges 19:: and 19b of the

wallboard units

14a and 14b will be in abutting side edge to side edge engagement with each other.

- After a series of wall units 14 are installed in the manner noted above on one side of the stu-d elements 2 the second series of wall elements can be installed in a similar fashion on the other side of the stud elements. As indicated in FIG. -3 a simple double channel member secured to a wall w or door frame can be used to anchor the endmost wallboard unit in a given series to the wall or door frame.

In the final hollow wall structure, it will be observed by reference to FIG. 4 that a suitable top runner or top channel 20 is used. Top channel 20 is provided with a web 21 of a width corresponding to the spacing between flange elements 8 of a stud element 2 and sides 22. Runner 20 is nailed to the ceiling c by means of nails which project through the outwardly projecting flanges 23 of this top runner 20. These top flanges 23 are generally of a width corresponding to the overall thickness of wallboard unit 14. The top of each stud element is cut away at 30 to receive and mate with the ceiling channel 20.

In one advantageous embodiment of the invention an angle shaped trim strip 24 can be inserted or sandwiched between the wall surface 25 and the top surface of the flange element 23 of the runner Z0. Mating continuous bead 26 on flange 23 and continuous bead 27 on the trim strip may be used to lock the trim strip to channel 20. In a further advantageous embodiment of the invention, in lieu of having a continuous bead on the flange element 23, the flange element 23 may have a cut away or struck out portion 33 provided with a bead 34. The horizontal flange of the trim strip 24 is then adapted to be inserted between the struck-out portion 33 and the undersurface of the main body portion of flange 23 with the

beads

27 and 34 mating with each other in the manner indicated in FIGS. 1 and 5.

As noted above, the flange elements 8 are disposed inwardly from or are spaced from the outer surfaces 4a of the side flanges 4 by a distance which is substantially equal to the thickness of the innermost ply of an overall wallboard unit 14 in the case of where the wallboard unit is made up of several plies. In the case of where the wallboard unit is made from a single ply provided with a rabbet groove 18 and lapping portions 17 and 17a this distance is substantially equal to the distance between the outermost surface s of the rabbet groove and the inside surface x of the unit. This same spacial relationship between a tab '8 and its associated side flange 4 is likewise true of course in the case of where wallboards of plural plies are anchored thereto. By virtue of the fact that the side flanges 4 and flange elements 8 project in opposite directions to each other while still being located in planes which are normal to the main plane of the web 6 of the stud 2 the wallboard units will fit in snug side edge to side edge abutting relationship while the inside surfaces of the units 14 are disposed flush with the outside surfaces of the flange elements 8 and with the wallboard units in a given series being interconnected in a lap joint arrangement.

From the above description it will be obvious that the stud elements 2 are so formed that they will hold up the wallboards at one side of the hollow partition even before the wallboards for the other side of the partition have been installed. This permits the ready installation of wiring, heating ducts and piping within the wall structure prior to its completion. In this connection the outwardly projecting struck-out portions or tabs 8 which form openings 35 in the web 2 of a stud element can be advantageously used for passing wiring or piping through the wall in the event such is desired. From the above, it will be observed that various component parts of the partition are so constructed that installation thereof is a simple and easy operation.

An advantageous embodiment of the invention has been herein disclosed and described.
