@60,4265 d V55/N6 BY M United States Patent O 3,320,710 PARTITION WIIH SUPPORTING SHAFT SECTION IN RABBET F FACER PANELS George J. Byssing, Los Angeles, Calif., assignor to Kaiser Gypsum Company, Inc., Oakland, Calif., a corporation of Washington Filed Nov. 15, 1963, Ser. No. 324,105 2 Claims. (Cl. 52-481) This invention relates generally to wall construction including floor-to-ceiling partitions and cornice partitions, and it relates more particularly to the ldetails of construction of studs and wallboards for forming a partition.

A partition of the general type to which this invention relates comprises studs and wallboards which are so constructed that they may be readily and easily interconnected. The vertical edges of the wallboards have slots for engagement with flanges on the studs. It is an object of this invention to provide a partition of that general type 'and in which the wallboards are interengaged at the stud connections in a lap joint arrangement, whereby the partition will meet building code requirements with respect to preventing passage of fire or flames into the partition at the joints.

The wall construction of this invention is especially advantageous when embodied in a hollow partition. For such embodiment, the wallboards for a full side of the partition may be installed and then those for the other side may be installed. Thus, after one side of the partition is completed, electrical conduits, lheating ducts and the like may `be arranged in the wall whereupon the partition may be closed and completed with 4installation of the wallboards for the other side.

Further objects and advantages of the invention will appear in the course of the following part of this specification wherein the details of construction and mode of install-ation of a partition embodying this invention are described with reference to the `accompanying drawing, in which:

FIG. l is a perspective View of a oor-to-ceiling hollow partition of this invention;

FIG. 2 is a sectional view taken along line 2 2 of FIG. 3 with portions added and other .portions removed and illustrates further details of the invention;

FIG. 3 is an enl-arged section through the partition taken along `a horizontal vplane indicated by line 3 3 in FIG. 1; and

FIG. 4 is an exploded detail section illustrating the manner in which a stu-d is connected to a wallboard according to this invention.

In FIG. l, the hollow partition of this invention is shown as installed in a corner of a room which is defined in part by room walls and 11, ceiling 12 and floor 13. The partition, designated generally by reference numeral 15, is formed of two wall sections 16 and 17 disposed at an angle with each other and interconnected along a vertical corner edge 18 `of conventional construction. The partition comprises a series of spaced vertical studs 20 and a plurality of wallboards, three of which in FIG. 1 are designated by reference numerals 21, 22 and 23, respectively. For convenience of reference herein, those wallboards, includ-ing wallboard units 21, 22 and 23, which appear in FIG. 1, are referred to as bein-g for the outside of the partition 15, and those wallboard units which are hidden in FIG. 1, but are represented in FIGS. 2 and 3, are hereinafter referred to as being for the inside of the partition 15.

The details 'of construction of the illustrated partition are described hereinafter in the order in which the cornponent parts of the partition are adapted to be assembled.

For the partition section 16, a wall runner 25, an upper or ceiling runner 26 and a lower or floor runner 27 are 3,320,710- Patented May 23, 1967 secured to the room wall 10, to the ceiling 12 and to the floor 13, respectively, to provide a framework by which the .partition section is mounted in the room. In the illustrated embodiment such wall, ceiling and floor runners are identical in cross-sectional configuration. Referring to the floor runner 27, for example, it extends throughout the length of the partition section 16 and is shaped to provide a medial portion 29 integr-ally formed with op` posed leg portions 30 and 31, the leg portions having terminated portions 32 and 33 which extend laterally outward from the lower edges of their respective leg portions. The runner 27 is fastened to the floor -as with nails 34 driven thro-ugh the terminal portions of the runner. For the illustrated embodiment, the runners 25, 26 and 27 have a common dimension between the outside surfaces of their opposed leg portions 30 and 31 which is equal to the dimension between the inside faces of the opposed wallboards for the sides of the |hollow partition.

When the runner framework is secured in the room, the wallboards and studs may then be fitted into place. As a beginning, an outside wallboard unit 21 of rectangular outline and defined by side edges 37 and 38, top edge 39 and bottom edge 40, is placed against the outside leg portions 30 of the wall, ceiling and floor runners. For the wallboard 21, its side edge 37, which abuts against terminal portion 32 of the wall runner 25, may be straight across between exposed or outer face 42 and hidden or inter-for face 43 of the wallboard. For simplicity in forming the wallboard units so that they will interengage with their next adjacent wallboard units in a lap-joint relationship, each wallboard or wallboard unit, c g., wallboard 21, is formed of ian outside panel 45 and an inside panel 46 which are secured together as with an interposed layer of adhesive 47. The panels, two of which form a wallboar-d of the illustrated embodiment, are` of conventional construction having -a plaster core 49 anda paper sheath-4 of generally right-angle Z-configuration in cross-section.

hav-ing a fiat web 54 and two parallel oppositely Idirected flanges '55 and 56 integral with and extending along and throughout opposite side edges, respectively, of the web. Web 54 has a plurality of vertically spaced sets of projections 58 and 59 which, in the illu-strated embodiment, are struck out from the web to leave an opening 60 in the web and are bent to extend at right angles to the web. In the case of the outside of the partit-ion 15, projection 58 extends at right angles from one side of the web 54 in the direction of the plane of the next-in-line wallboard 22 while its near ange 55 extends from the other side of the web 54 in the plane of wallboard 21. The

plane of the projection 58 is spaced from the plane of the ange 55 by a dimension about equal to the thickness of .an inside panel 46 so that when the wallboards 21 and 22 are interconnected in a lap joint arrangement with a stud 2G, the projection 5S will lie fiush against the interior face 43 of the wallboard -unit 22 and the flange 55 will lie fiush against the inside face 61 of the outside panel 45 of wallboard 21. For an understanding of this invention, it is of no consequence that in the illustrated embodiment the outside panels 45 of the wallboards yare thicker than the inside panels 46.

For the wallboard-stud connection which appears in FIG. 3 and includes wall boards 21 and 22 for the exposed or outside of the partition sect-ion 16, the vertical side edge 38 of the wallboard 21 is defined by a land edge 64 (side edge of outside panel 45) extending substantially perpendicularly from outside or exposed face 42 of wallboard 21, and a vertically extending rabbet 65 of substantially right-angled cross-section open to the interior face 43 of the wallboard 21,y the rabbet being defined by an inner lap-joint side surface 67 (continuation of inside face 61 of the outside panel 45) extending substantially perpendicularly from the land edge 64, while the other side of the rabbet is defined by a recessed edge surface 68 (the same as a side edge of the inside panel 46), such recessed edge surface extending substantially perpendicularly from the interior face 43 of the wallboard 21. That portion of the outside panel 45 which extends beyond the recessed edge surface 68 (side edge of inside panel 46) is designated by numeral 69 and is referred to herein as being a lap portion.

The wallboard 21 has a vertically extending slot 70 kat the vertex of the rabbet and open to the recessed edge surface 68. For the illustrated embodiment, the slot 70 is conveniently provided by making a bevel 7-1 on the inside surface of the inside panel 46 at its side edge 68. The flange 55 of a stud 20 fits frictionally tight into the slot 70 with the web 54 of the stud being seated flush lagainst the recessed edge surface 68 of the wallboard 21.

The studs 20 are so formed that they will vhold up` the wallboards 21, 22 and 23 for one side of the hollow partition even before the wallboards for the other or hidden side of the partition have been installed. It is not necessary that the studs 20 be of a length to extend fully between the floor and ceiling runners, and for the illustrated embodiment the stud 20 in FIG. 2 has its lower edge 73 spaced above the floor runner 27, i.e., the stud is shorter in length than the height of the partition. At their upper ends, the stu-ds 20 have a rectangular cutout 75 for spanning the medial portion of the ceiling runner whereby the stud has end portions 76 and 77 whichextend beyondthe bottom ofthe cnt-out 75 for engagement against the outside surfaces of the leg portions 30 and 31, respectively, of the ceiling runner 26. Thus, the stud and wallboard 21 are prevented from falling from the runner framework.

After placement of the wallboard 21 and a stud 20 into the partitionframework, the next wallboard 22 is set into its place for continuing with installation of the partition by seating the wallboard 22 against the ceiling and oor runners and sliding it sideways for engagement with the wallboard 21 and the stud 20. The wallboard 22 has a lap port-ion 79 and a rabbet 80 complementary to the rabbet 65 and the lap portion 69 respectively of the wallboard unit 21 such that t'he wallboards 21 #and 22 become interengaged in a lap-joint relationship. In the sideways movement of the wallboard 22 toward the st-ud 20 and wallboard 21,' the lap portion 79 of the wallboard 22 becomes positioned between the lap portion 69 of the wallboard 21 and the projections 58 `of the 'stud 20 thus to hold the wallboard 22 in coplanar edge-to-edgel abutment with respect to the wallboard 21, land the wallboard 22 is Iheld by the stud against falling from the partition framework.

The side edge 82 of the wallboard 22 disposed in adjoining relation to the next-in-line wallboard 23 las indicated in FIG. 1 has a lap portion, rabbet and slot corresponding in size and shape to the lap portion 69, rabbet 65 and slot 70 of the wallboard 21 for forming a wallboard-stud connection with the next wallboard in line, i.e., wallboard 23. Inasmueh as lap portions at opposite side edges of each wallboard are of the same dimension, taken in the plane of the wallboard, it is apparent that for forming a wallboard unit, e.g., wallboard 22, of a standard width, the outside panel 45 and the ins-ide panel 46 thereof are of the same width.

Upon completion of installation of the wallboards 21, 22, 23, etc., for that side of the partition which is exposed in FIG. 1, the partition is still open at its hidden side for installation of such electric conduits, pipes, or heating ducts, etc., -as 'are desired. It is then but a simple matter to complete the hollow partition by placement of wallboard units 85, 86, etc. (FIG. 3) for what has herein been referredto as the hidden side of the partition, such wallboards being interconnected in edge-to-edge lap-joint abutment and interlocked with the flanges 56 and projections 59 of the positioned studs.

In view of the foregoing, it will be apparent that the component parts of the partition of this invention are so constructed that installation thereof is a simple and easy operation. It is important to note further that the lapjoint relationship of adjacent wallboard units provides an arrangement infwhich there is no straight crack between the outer and inner faces of the Wallboards for one side of the partition. Thus, when a llame from a torch, for fire resistance testing purposes, is directed toward the crack 38, for example, the flame will not passfto the stud, and the partition will be found to meet the rigid requirements of sustaining resistance against llames, as is required by building codes.

After the wallboards have been set in place, the partition may be trimmed along the Wall, ceiling and floor of the room as with snap-in strips 89, and 91, each'of which, in the illustrated embodiment and referring in particular, for example, to trim strip 91 which serves as a base board, is an angle strip of two legs 93 and 94.

The leg 94 is designed to fit under the terminal portion i 32 of the floor runner 27, and it has a longitudinally extending bead or ridge 96 for mating with a complementary groove 97 formed in the terminal portion 32.

While the instant invention hasy been shown and described herein, in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is thereforenot to be limited to the details disclosed herein, but is to be accorded the full scope of the claims.
