23 Claims.

The general object of this invention is to provide a system of wall construction by which walls having the essential desirable operative characteristics of well constructed plastered masonry walls, including the usual jointless finish when desired, may be erected and re-erected a number of times without substantial loss of the materials or impairment of the parts composing the wall.

A further object is to provide a wall comprising a steel framework and sheets or slabs covering the framework, wherein there is no steel exposed on the outer faces of the sheets or slabs.

A further object is to materially reduce the time involved in erecting partitions and other non-bearing walls in buildings, whereby alteration of spaces therein will not occasion such long periods of disuse of the spaces altered as commonly experienced.

Another object is to provide a non-bearing wall having the essential desirable characteristics of masonry walls of this class but which may be dismantled without damaging the building surfaces from which the wall is removed, (floors, ceilings, outside walls and columns e. g.) and which may be economically reerected largely, if not wholly, from the same parts either in the same or in a different arrangement thereof.

Another object is to provide a non-combustible wall having heat and sound insulation characteristics comparing favorably with double plastered conventional walls of equivalent thickness and capable of being re-erected several times without substantial loss of material and economically from the standpoint of time involved.

A further object is to provide a novel method of wall construction obtaining essentially the operative results of a heavily plastered masonry or plastered steel frame wall without requiring a plastering operation and attendant long drying period.

A further object is to provide a wall including steel frame parts and having a heavy plaster sheathing for carrying the desired decorative or other coating or finish, wherein the steel parts are not subjected to the corrosive effects of moisture during erection of the wall, as in the case of having to apply wet plaster, as on lath or the like, to obtain such heavy plaster sheathing.

Other objects include the provision of a double wall either side of which is complete in itself and can be so used; either side of which can be easily and quickly taken down for the installation of pipes, vents, etc. and re-erected using the same parts; and which in re-erection may in a simple manner be extended outwardly from the wall framework to accommodate pipes, vents, etc. placed in the wall.

Still further objects include the provision of various improvements in frame structures for partition and other walls, which structures may be quickly, sturdily and accurately erected by the same class of skilled workmen employed to finish the wall; improvements in structural framework with the view to accommodating, plumbing, electric service wires, conduits, etc. within the wall structure; improvements in securing devices, extensions and couplings for rolled steel studs or frame members, and improvements in anchoring devices for securing plaster e. g; slabs, sheets, etc., to structural framework for partitions and other walls.

Other objects and novel features of the invention will become apparent from the following description wherein reference is made to the drawings:

In the drawings:

Fig. l is a perspective view showing one embodiment of the invention in the course of construction, the particular embodiment being a partition; Figs. 2 to 5 are perspective views, each on a larger scale, of various details of the structure shown in Fig. 1; Fig. 5a is a sectional detail view taken on a horizontal plane cutting a stud and showing an extension anchor for holding slabs in spaced relation to the studding; Fig. 6 is a. sectional view taken on a horizontal plane showing a corner detail; Fig. 7 is a perspective view showing the manner in which the preferred stud extensions and/or couplings are locked in position on the studding; Fig. 8 is a vertical sectional elevation taken through a stud in the plane of the wall centrally thereof showing a fragmentary section of wall slab and the preferred form of slab anchoring device; Fig. 9 is a vertical sectional plan taken on a plane horizontally cutting the stud and showing at one side the manner of securing the slab attaching device thereto; Figs. 10 to 13 are perspective views of modified forms of slab anchoring devices, also certain contemplated modifications of slab detail; Fig. 14 is a vertical section through a wall using a slab having a still difierent edge detail, the anchoring device being modified in accordance therewith.

Referring again to Fig. 1, the surfaces of the ceiling, a vertical wall and a floor bounding a space to be partitioned are indicated at A, B, and C, respectively. The near wall and portions of the ceiling andfloor are broken away for clearness of illustration.

The location for the partition having been marked off on the surfaces A, B, and C the plane of the wall is then fixed by applying guide strips I to said surfaces, preferably continuously about the space except where the surfacesare to remain clear as at doorways. The wide strip may comprise thick flbreboard, wood, etc. and may be cemented in place or nailed or both; in any event it should be securely fastened.

Door and window bucks may be erected following conventional practice; part of a wooden door buck 2 with transom rail 8 and lintel 8, being shown by way of example.

The metal parts of the partition frame comprise flanged studs 5, one being shown in two parts or sections 5' and 5",-stud extensions or sleeves 8 (identical at top and bottom). ceiling plates 1 embracing the ceiling guide strip and to which the upper stud extensions are secured,

floor plates 8 embracing the guide strip on the floor and supporting the studs through the medium of the lower stud extensions engaged thereby,and devices 9 adapted to interlock with the studs and arranged to anchor the wall slabs ill (to be hereinafter described) to the studs.

The preferred form of stud is a channel, standard furring channels being suitable-these having the required stiffness for non-bearing walls. A channel measuring about 2 across the back is recommended for partition work, say inoflice buildings and the like of average height. 1-or load bearing walls heavier channels are used. The term stud" for the main frame member 8 is used principally for convenience'in view of the fact that the principles of the present invention may be applied to ceilings e. g. and since in some cases the frame members corresponding to the studs herein shown would run horizontally. In some cases Z bars and angle bars may be used in place of channel bars. I- beam sections may also be used.

In order that cutting of studs to flt, during or preparatory to erecting a wall, will not be required, and for other reasons that will appear hereinafter, the studs are furnished shorter than necessary to reach both the ceiling and floor guide strips, and the studs are provided with the extension sleeves 8 at both ends. These comprise web portions l5 and side and intumed flanges l8 and I1 respectively, the flanges being adapted to snugly receive the stud ends so as to be retained securely in place during setting of the studs. At one end of each sleeve 6 is a tongue l8 projecting from the web substantially at a right angle, and the web is provided with a series of openings i8, beginning adjacent the tongue.

It is important in order to better resist strains on the wall normal to the plane thereof to increase the effective horizontal dimensions of the studs in the plane of the wall at both ends where the studs operatively engage the guide strips. This increase is afforded by the plates 1 and 8 as will be apparent from inspection of the drawings.

The ceiling plates I are channels, the webs of which lie flat against the face of the guide strip with the flanges 20 snugly embracing the edges of the strip and of suflicient length to form a wide bearing on the strip both horizontally and vertically. The plates I (also the floor plates 8) channel effects of the plates I and 8 to prevent rotation of the stud on a vertical axis.

The floor plates 8 form saddles for the studs and are constructed similarly to the plates 1 but have, in addition, stirrup portions 24, formed as extensions of the flanges 20a of the floor plates, adaptedto receive the lower edges of the slabs HI (see Fig. 3).

It will be noted from Figs. 1, 2 and 3 that the openings l8 in the extension sleeves provide access from one side of each stud to the other in the central plane of the wall, thus accommodating conduits etc. both at the base and top of the wall. Attention is also called to the fact that the upperand lower-most openings I9 terminate as archways at the tongues l8 so as to facilitate placing say flexible conduits or wires in a partially or wholly erected wall past several studs. Since the lower opening l9, as shown in Fig. 3, terminates in this manner flush with the top-side of the floor plate 8 and since this top surface is substantially planar it is an easy matter to insert such conduits or wires through the openings in the extensions from one stud to another past several studs, the fishing end of the conduit or the flsh wir in case of a bundle of wires being supported by the guide strip I, and easily sliding over the slight abutment presented by the end edge surfaces of the floor plates. Since the tongues I8 lie entirely below the raised por- Fig. 1, may be thus afforded (through the openings I! in the connecting sleeve) at any portion of the wall.

To set the stud in place, the preferred procedure is to flrst attach the extension sleeves 6 to the opposite ends of the stud, definitely locating the lower sleeve to provide the desired open space for conduits and the like through the openings IS. The position of the sleeve is maintained by crimping the flanges I'I inwardly as at 25, Fig. 7, as by means of a pair of pliers, thus providing abutments adjacent the ends of the stud flanges. The upper extension sleeve 8 is then located so that the overall length of the stud including the extension sleeves is somewhat less than the height of the space in which the stud is to be erected. The floor and ceiling plates are now assembled onto the tongues i8 of the sleeves 6 and the stud swung to vertical position. The floor plate 8 is then set down in the desired location on the lower guide strip. The ceiling plate I is then raised into embracing relation to the ceiling guide strip which may be done while standing on a step ladder by lightly tapping the lower end of the upper extension sleeve 8 with a hammer. When the upper extension sleeve is thus raised as far as it will go tie flanges ll of this sleeve are then crimped at tl.e upper extremities of the flanges of the stud (of. Fig. 7). If the stud is out of plumb it may be moved by driving one of the plates 1 or 8 in the required direction on the guide strip. The plates 1 and 8 may then be nailed onto the guide strips as through the openings 21 in the respective plates.

It is highly important that the studs be prevented from moving in either direction in the lower margins of the blank forming the clip 35 plane of the wall at both ends of each stud and from being twisted out of position. As will be seen from Fig. 2 the necks Ilia connecting the web portions 15 of the extensions 6 to the tongues 18 are only of sumcient length in the direction of the webs to lie within the slots 22, the flange portions it of the extensions abutting adjacent flat surfaces of the ceiling or floor plates as the case may be (see Fig. 3) when the studs are in position, in other. words, extending at right angles to the ceiling and floor plates. Thus the studs when in upright installed position cannot be moved in any direction with respect to the ceiling and floor plates nor can they become displaced by rotation about their respective axes.

The detailed construction of the slab attaching or anchoring devices 9 varies somewhat in.

accordance with the edge detail of the slabs, the shape of the stud, and in accordance with the manner in which the slab is to be secured, i. e. whether single devices are to secure the edges of one or both adjacent slabs. The primary purpose being to form a strong, tight wall without necessarily requiring a plaster coating, a slab with interlocking edge joints is most desirable, that is to say wherein one slab holds another in position against movement in at least one horizontal direction, and the construction of attachment device adapted particularly for slabs with edge details forming conventional rabbet joints will be first described.

The slab edges as shown in Figs. 1 and 4 have oppositely oilset tongues Ill and I I3", and the slabs are set against the studding in such manner that the lower tongue of anupper slab sets behind the upper tongue of the under slab, consequently it is only necessary to secure the upper edge of each slab to the studding, assuming the lowermost slab has its lower edge properly secured. In view of the primary purpose above stated, engagement of the slabs to secure them to the studs is efiected inwardly from the outer faces of the slabs and the present arrangement including the improved slab attachment or anchoring device accomplishes this and the slabs are held in an exceedingly eificient manner permittinga given wall to be expeditiously erected and re-erected indefinitely using the same parts.

Referring to Fig. 4, two slab anchoring devices are illustrated each comprising two parts: a slab anchoring plate 3!! and a clip 35, the latter being arranged to engage and interlock with the stud and to simultaneously rigidly secure the plate 3b.

The plate 3i may be economically made from an elongated rectangular sheet metal blank, and has a central depression 3i (see Fig. 9 particularly) extending entirely across the plate, and outstruck aligned tongues 32 the ends 33 of which are pointed and bent to extend nearly parallel to the plane of the plate, (slightly outwardly inclined to draw the slab toward the stud) the points 33 being in a common plane. The tongues 32 are wider adjacent the body of the plate than at the bases of the points so as to better resist bending or being sprung when the points are driven into the slab, as will be presently described.

The clip 35 may likewise be economically formed from a rectangular sheet metal blank and has a rectangular central body 36 substantially fitting the depression 3i which latter is ordinarily of a depth equal to the thickness of the stock from which the clip 35 is formed so that all the slab contacting faces of the entire device will be flush with each other. Extending from the upper and are tongues 31 and 38. The opposite ends of the tongues are struck back and snugly straddle the plate 30 whereby the body portion 36 of the clip is further definitely located in the depression 3i against any relative rotation (skewing) of the two parts of the device. The struck back portions of the tongues are formed to provide paired yielding lugs or hooks 40 (see also Figs. 8 and 9) to interlockingly engage the free edges of a stud channel flange and to provide paired yielding abutment fingers 4| for frictionally and yieldingly engaging the web of the channel stud at the base of the flange to hold the lugs 40 firmly interlocked with the flange of the stud.

It will be noted in Figs. 4 and 9 that the lugs or hooks 40 extend about the flange oi the stud 5 clear thereof and contact with the inner surface of the flange inwardly (toward the web) from the edge of the flange, whereby each lug or hook may accommodate flanges that vary somewhat in width and nevertheless tightly'grip such flanges due to yielding of the hook-shaped lug.

The gripping of the studs is for an overall effective distance longitudinally of the stud such that the clip is guided for substantially right line movement along the stud (without becoming skewed) notwithstanding the application of an unbalanced force on the clip (as by a blow of a hammer on one side or the other of the clip, see below) to move the clip downwardly on the stud in securing the slabs. In the form shownsee particularly Fig. 8-it is evident that the effective gripping distance along the stud is about three times the total width of the stud flange. The actual effective distance may be varied in accordance with the thickness and temper of the stock used to form the lugs and fingers, but for studs of the proportions shown, and for the thickness of the clip stock shown, a gripping distance of from two and one-half to three and one-half times the stud flange width is ample.

It will be noted that the unbent webs connecting the lugs and fingers 40 and 4| lie in the same plane with the central portion 36 of the clip whereby the web is spaced from the underlying surface of the stud a distance corresponding to the thickness of the plate 30. By this means the metal of the clip in the plane of the portion 36 (at the neck connecting the lugs and fingers to the central portion of the plate) yields to accommodate any variations in the thickness of the stud flanges, should the yielding of the hooks be insufilcient, as well as to accommodate other variations, say in the formation of the hooks 40 or thickness of stock used to make the anchor parts. i

The lug and abutment device just described may be just as effectively used with an I-beam stud or frame member section or with the flanges of simple angle bars or Z bars.

The free ends of the fingers ti are curved outwardly somewhat to assist in springing the assembled device (plate and clip) onto the stud. This is accomplished as shown in Fig. 9 by first hooking the lugs 40 onto the stud flange and -then forcing the assembled device toward the stud as by thumb pressure (indicated by arrow in Fig 9) on the margin of the body portion of the clip, rotating the clip about the flange contacting portion of the lugs or hooks as a center. 7

When interlocked with the stud as above described the-slab anchoring device 9 cannot be pulled off except by swinging the same about 4 '1,ooa,osa

the hook, reversely to attaching the'device, nor moved in any butone direction,.n a'mely; up and down the flange. The points 33 are held rigidly in position to simultaneously pierce the slab as above described when the anchoring device is driven downwardly on the stud as by a blow of a hammer where indicated by the arrow on Fl 4.

t furring of the slabs is desired for any reason, say to better accommodate pipes, vents, conduits, etc. is a wall already erected without such elements, this may be accomplished by forming the end portions of the plate 30 which support the tongues 32 in a plane outwardly offset from the vertical edges of the body portion 35 of the the adjacent slabs for a considerable distance horizontally, thus greatly assisting in maintaining the edges in alignment; and-having in mindthe dissimilarity of thetwo sides of the stud and. that the prongs 38 must always extend downwardly-the anchoring devices may be used interchangeably on either side of the wall (clip 35 merely needs inverting to meet the two conditions shown on Fig. 4)

choring devices generally may be modified to clip 35 as suggested in Fig. 5a. Here the slab erigage slabs, sheets, strips, etc. in the various engaging portions of the plate 30 are shown as connectedwith the central portion by outwardly extending arm portions 30a of the plate 30.

Referring again to the preferred form of slabs these are preferably formed from a body of high grade gypsum plaster but may be of any other suitable composition-say for obtaining higher thermal insulation or sound absorption or sound insulation etc. values; the plaster body being contained in a suitable strengthening and/or protective envelope 45-say chipboard or other heavy paper. The envelope is folded about the edges of the slab (may be done in a board mill such as are commonly used to make plaster board, plaster lath etc.) in such manner that the joints, which are overlapping edges as shown, see 45' and 45", Fig. 4, occur on the inner surface adjacent the studs, the entire outer surfaces of the slabs being continuous and jointless.

It will also be noted that the overlap of the envelope sheets occurs opposite the portions of the plate 30 which contact with the slab edges, thus reinforcing the envelope where it is most likely to be torn as by burrs on the anchors e. g. The slabs are preferably from to 1 inch thick, 2 feet wide and from 8 to 10 feet long (as cut on the mill e. g.).

Reverting again to the anchor devices 9 and particularly the plates 30 and slab engaging prongs 32-33 it will be apparent from the above discussion of the slab that the points or prongs 33 which preferably have an efiective-length of 1%" to /4" will penetrate the usual paper envelope and enter the plaster body, fully interlocking with the slab when the anchoring device is seated. Prongs of the proportion shown, notwithstanding the slight inclination outwardy from the plate 30 to draw the penetrated slab theretowarid, do absolutely no damage to the slab and the slab, in being used over again, may be engaged in the previously made openings and still be effectively secured. When a second slab is set on top of a slab secured at its upper edge by the anchoring devices described, the lower tongue thereof (see l" Fig. 4) engages the flat faces of the horiozntal portions of the tongues 32 and the weight of this second slab further insures that the prongs will remain interlocked with the slab secured thereby.

Further desirable features of the anchoring device are that any outward pull of the slabs is imposed on the plate 30 and clip 35 centrally of both since these parts are substantially symmetrical on opposite sides of the tongues 32; the interlocking engagement between the tongues 40 and H provide sufficiently wide apart bearing on the stud to insure parallelism of the anchoring device with the stud and slab; the plate 30 continuously contacts both inner marginal edges of I ways shown by the prior art. In the case of using slabs presenting a fairly broad upper edge surface, slab piercing devices separate from the tongues of the plate 3| may be used (nails, staples eta-not shown-engaging suitable modified tongues corresponding to the tongues 32). It is obvious that the anchoring devices may be disengaged from the slabs and studs. in dismantling the wall for re-erection or storage of the wall parts, the procedure being the reverse of the manner of engagement with said parts.

In Fig. is shown a detail of the condition 11- lustrated in Fig. l where two slabs l0 terminate, as at I: Fig. 1, in overhanging relation to the studding. The part 30 only of the improved anchoring device may be used as illustrated to fully secure the edges, (partly in conjunction with the slabs above and below the joint which bond withthe slabs so terminating).

One manner of forming a corner with the improved wall is illustrated in Fig. 6. Assuming the portion of the wall (slabs at I08 and Hit) has been set up in accordance with the previous description with the endmost stud 5 set fairly close to the end of the erected wall where the comer is to occur, as illustrated, a vertical guide strip is located at the edges of all the slabs in the position "3, say cemented on or nailed on. The stud 53 in the positionshown forms a rigid backing for the wall which may now be-erected to the right of the slabs I08 and lit starting with the guide strip in accordance with the above descrlption. The slabs Ills may be cut oil at lbs or shorter since these ends are concealed in the finished wall. The slabs in the position llv overlap the outer edge of the guide strip and abut the slabs at lot. erected the protruding ends of the slabs "It may be nailed to the slabs at lllv and are then sawed off squarely as at Hit. The inner row of slabs at lOw abut the slabs Ills and their margins lie adjacent the guide strip His as shown and the slabs at both lllv and Him may be nailed to the guide strip in an obvious manner.

When the wall is erected the horizontal joints and all others are carefully pointed and made smooth, and the wall surface then given the usual sizing and/or any desired decorative or other coating. No plaster is necessary or desirable if the wall is to be re-erected using the same slabs.

The modified anchoring device 50 shown in Fig. comprises a single metal plate having lugs or hooks 5| corresponding in general function to the lugs 40 previously described, and abutment fingers 52 outstruck therefrom to engage the web of the stud. If this device 50 is to secure slabs according to the above description, that is to say, to secure the same by points or prongs as at 53 engaging one slab edge only, then the two sets After these slabs Illvare of lugs 51 are essential to enable interchangeably fitting both flanges of the same stud. However, one lug 5| may be dispensed with if the device 50 may be used either side up as in the case of hav-' ing additional slab engaging means (points 54 e. g. shown in broken lines) so as to interlock with both adjacent slabs.

Fig. 11 shows a different manner of making a one piece clip and also a modified slab detail. Here the lug and abutment finger arrangement SI, 62 is more nearly the same as in Fig. 4, the lug and abutment allowing the plate 60 to be slid on the stud while interlocked therewith to enable interlocking engagement with slabs, the latter being as shown, grooved on both edges at G. T-shaped slab engaging lug member 60a are shown, the head of the lugs engaging both grooves.

Fig. 12 shows an embodiment of anchoring device 65 also adapted to be made from a single piece of sheet metal but having the stud engaging lug 66 and stud abutment fingers 61 located in pairs at the top and bottom edges thereof. Preferably the lug and finger supporting portion of the plate is offset slightly outwardly from the central portion of the plate as at 68 so that the necks connecting the lugs and fingers -G661 with the body of the plate may be sprung somewhat as required by variations in the stud flanges e. g. the same as in the case of the two piece anchor above described. Fig. 12 shows prongs 69 for engaging the slab turned both ways whereby two adjacent rows of slabs may be secured in substantial alignment with no interlocking formation between the slab edges. The slab edges are shown as perfectly fiat. In this case nails, staples, etc. may be'eifectively used say in suitable openings punched into flat tabs (not shown) bent outwardly from the body of the anchor and adapted to lie between the adjacent edges of the two slabs.

Fig. 13 shows a one piece anchoring device wherein spaced portions of the upper and lower edges of the metal plate 10 are bent to lie parallel to each other forming two pairs of flange engaging hooks H and intermediate channel web engaging abutments 52a between the two pairs (corresponding to 52 Fig. 10). v

If the edge detail of the slabs comprises a simple tongue and groove arrangement as shown in Fig. 14 the interlockingengagement between the slab attaching anchors and the slabs may comprise extensions 12 of the anchors (corresponding to the arms 32, Fig. 4) with depressed outer extremities I2 substantially complementary to the groove. The remainder of the anchor construction may be in accordance with any of the previously described illustrative embodiments of anchors. To simplify the construction of the anchors the slabs on one side of the wall may be set with the grooves up and the tongues down, and on the opposite side of the wall with the grooves down and the tongues up as shown. As illustrated the arrangement of stud flange engaging hooks l3 and fingers I4 are substantially in accordance with Fig. 11, which see.

It is to be understood that all the above described sheet metal parts may be suitably treated by any known process to resist corrosion. No special treatment is usually found necessary for ofiice, school, church, buildings and the like.
