12 Claims.

The present invention relates to an improvement in building construction, involving the combination of wire studding and plaster boards together with suitable clips for the attachment of said boards to the studding in a rigid and secure and a core of cementitious material, or boards.

or sheets made of ceramic materials or of metal, either perforated or not, or any other equivalent structure which is capable of receiving and holding a coating of plaster.

The invention also concerns itself in part with the clips employed for fastening the plaster board to the studding and with combinations of the studding, clips and plaster boards when erected, ready for the reception of the plaster coating.

One of the objects of the invention is to provide relatively inexpensive, substantially incombustible and conveniently assembled means for the erection of partitions and walls which may extend either vertically or horizontally, comprising, for example, vertically extending wire studding composed of two pairs of longitudinally extending strands to which there has been.

welded a transversely extending web-forming portion of strands which may extend either ob-. liquely or at right angles to the strands and which preferably are located between each of the strands, constituting a pair, and being spot welded or otherwise rigidly secured to the strands. In co-operation with this type of studding there is a particular and special type of clip which has an elongated central portion and fingers extending therefrom, forming, together with the longitudinal central web or portion, a flange or flanges for the reception of the edge portions of plaster boards, the clip also having a rearwardly extending flange which itself is cut and bent so as to provide at least one bendable tongue and, preferably, also another relatively rigid tongue, the latter for abutment against a strand of the studding and the other sufiiciently bendable to adjust itself when the clip is attached to the studding by the erector, so as automatically to as a result of which the clip is attached to the wire studding rigidly and Without movement toward or away from the studding, so that the plaster boards will be held rigidly thereto with substantially no play.

Further details will be readily understood from the further description herein when read in connection with the drawings filed concurrently herewith, in which Fig. 1 is a plan View of a piece of sheet metal suitably slotted and stamped so as to provide a blank from which the clip is made;

Fig. 2 is a perspective View from the rear of the completed clip, substantially on a full size scale;

Fig. 3 is a view from the rear of a portion of the clip when attached to the studding;

Fig. 4 is a sectional View of a part of the stud: ding, looking down from above, showing the two strands thereof and their manner of engagement with the clip and the aforementioned tongues N Fig, 5 is a view similar to Fig. 4 but showing the clip in engagement with a double pair of strands;

Fig, 7 is a vertical section through a completed wall, showing some of the plaster boards in section and showing an elevation of the stud: ding and corresponding end view of the clips in engagement both with the plaster boards and with the strands of the studding; and

Fig. 8 is an elevational View of a portion of a completed wall, containing plaster boards and flips, ready for the reception of the plaster ,coat

Referring to Fig, l, which shows some the steps employed in making the clip, it will be seen that this comprises a sheet of metal broadly designated by'the reference numeral II). This piece of sheet metal has an elongated central portion II which preferably, but not necessarily, is provided with a central rib I2 for the purpose of rendering it relatively rigid and not easily bent in use. By suitable cuts I3 and I4 the two sidewardly extending portions of the sheet relative to the central portion II are divided into a number of individual fingers I5 and I6 while cuts I1, I8, I9 and I9 permit the formation of a rearwardly extending flange F which in one embodiment is provided with tongues 20 and 2| of a bendable nature and a comparatively rigid tongue 22 having a substantially centrally located rib or indentation 23. The blank also has a subadJust itself to the distance between the strands.

an angle downwardly and lug 26 at an angle upwardly, whileadjacent the lug 26-and inwardly therefrom there is the angularly upstanding tongue 22, which is rendered rigid by'being b'ent or slightly ribbed asat 23'. The purpose ofj'doing.

this will be explained later in connection with the manner of use of the clip. Adjacent the lug 2-5 and inwardly therefrom there may be one or two bendable tongues and 2| which, as the clip is made and furnished to theuser; extend. substantially in the same plane as the lug while the rigid tongue'22 is out of th plane of the lug 2'8 and may be entirely vertical but preferably is slightly inclined toward the central space of the flange F. The cutaway portion 24 has already been mentioned in connection with the flange. v V

Referring for the moment to Figs. 6 and 7, it

will be seen that there is provided a vertically extending wire studding c'onsistingof'two pairs of strands and 30" which are connected by transverse obliquely extending 'web forming wires 3| and, if desired, one or more transverse individual wires 32' (Fig, 7),. these being welded between each p ir of strands so as to unite the strands together with the transverse webE-for'm? ing members to form a unitary stud. Th'ejstud itself is somewhat less in length than theQdistance from the floor to the, ceiling, which it intended to subtend, the restof the distance be.- ing made up by the employment of an auxiliary adjustable extension piece which consistsOf a. transverse portion 33 and two downwardly de.; pending members which between them grasp the. crosspiece 32 and which themselveslieimrnedi ately behind the

strands

30 and 30? of the CQIlfl". pleted, erected studding, this constructionbest.

beingseen by a perusal of Fig. 7 and in section on Figs. 4 and 5. By slidin the extension piece v until itstrikes the ceiling and securing it for example by staples 34' driven into a wooden scantling or beam 35, this extension piece is fastened to the ceiling' At the same time,'stapl es' .6 34 are fastened across the transverse piecef32fi Alternatively, a metallic,

adjacent the floor. channel runner may be provided, having. suitable holes through which wires may be passed and fastened to the studs, this runner being secured to the ceiling and floor, respectively, The extension piece and the stud proper are fastened together by means of tie wires and 36';

Referring'nowto Fig. 3,'thi's shows a difionf of rthe strands stand 30""viewed from a position 23- can-thuspla1nly be seem-and it will be noticed thatlthe tongue 2 2-,*because{o f' its bent form; will-force or -pr'essthe strand 3!! against the seen'that the tongue '2-Whas': been bent as a result at the rear of one of the pairs of strands, shOW- ing the clip in its final position. It will be noticed that the central web or portion H of the clip extends at substantially a right angle to the general direction of the

strands

30 and 36. The upstanding relatively rigid tongue 22 abuts against the side of the strand 36 while the lug 2B subtends the rear surface of the strand 30 so that it isv impossible to pull the clip away from the strand because of the interlock thus produced. The lug 25 subtends the other strand 30' th e bendable tongue 20 (assuming for the moment that in that particular clip there is only one o these tongues) having been bent further down tha-nti ts original position, tangent to the side of, the. strand 30'. The clip is placed onto the strands-in an oblique position and then bent so. that the central web is at right angles, thereby bending the tongue20 and thus automatically proyiding. for a span between the tongue 20 and the tongue 22 of exactly the proper distance to preventsideways movement of the clip. This is an important feature which completely differentiates the. clip offth'e present invention from any clips of the prior art; none of which had this featuraof 'automatie adjustability. By making the tongue 22- relatively rigid" it will not bend when the, clip is placed, in' horizontal position, but the tongue 20 willbend. A possible alternative is to make tongues 22,20 'and'2 [of the same degree of bendability, withoutresorting' to making tongue 22 less bendable.

If theclip is ofthe configuration. shown in Fig:-2, -the tongue 2-l-will lie directly behind the lugf25; as seen in Fi ,3;this tongue 2 I thus performing thesame function as the lug 25. In other words, if the clip'i's to be used at all times with -a stud havingfm erely' a single pair of strands; the slit 29whichsCparates the tongues 20 and' 2'I-' nee'd n0t be made, for in that case the clip when -viewed from above" can readily be seen.

At the right-hand side of the drawing it will'be of its- 'contaca an the 7 strand 3t! while the tong-'uefZl remains substantially 'unbent, in that case subtending the rear surface of the strand 30 thus also holding'th'at strand in close coni-th the shoulderf'of the web I l Inasmuch as it isdesi'red toslide these clips up'and'do'wn along-the strands of'the stud'din'g to permit its adjustment'adcording to: the size'of 'the plaster boardsemployed, and because of the fact that the-transverseoblique as'well a s'hor izontal webforming members Stand :32" project slightly beyond the pairs" ofstrands". of. the studding, the cutaway'portion 24:is provided so that these excli-Pi; F

readily beseen. tnaticasefthe strands are doubled, one beyond the other, being designated in Fig. by the

numerals

30 and 30 and 30a and 30a. In this construction the lug 26 Slllbtends the rear strand 30a while the lug subtends the rear strand 38a and both tongues 20 and 2| are bent downwardly so as to lie against the strands 38 and a respectively, while the relatively rigid tongue 22 with its central rib 23 abuts the strands 30 and 38a respectively.

As can be seen from Fig. 8, plaster board edge portions are inserted into the flanges provided by the fingers l5 and I6 respectively, the clips lying both at the central portion and the edge portions of the plaster boards 41] (Fig. 8). It is preferable to mount the boards in staggered relationship, and if desired they may be of the perforated plaster board type. Some indication is given in the drawing of the use of this type of plaster board, although, as above mentioned, the type of plaster board is a matter of indifference so far as the present invention is concerned, and the illustration of perforated paper-covered plaster boards is to be construed as merely exemplificative and not at all limiting.

The tops and bottoms of the boards are secured to the studs by comparatively simple clips 5| which are suitably fastened to the studs. These clips merely have upstanding flanges which subtend the lower edges of the lowermost boards and the uppermost edges of the topmost J boards. The boards can be sprung into these clips at the top. Alternatively, nails driven into the floor and ceiling may secure the ends of the boards.

The present construction provides a very rapid means of erecting a wall or partition. For example, a workman applies one part of the studding to the ceiling by means of the staples 34 and then slides a corresponding piece of studding into sufficient overlap with the first portion, securing the bottom thereof to the floor by means of the staples 34', then tying the strands of the studding together by the

tie wires

36 and 36. This therefore constitutes the vertical supporting means to which the clips are then attached. There may first be laid along the floor, and extending vertically, a lowermost row of plaster boards 4| (Figs. '7 and 8), using, for example, clips 5|, or driving nails in front of the boards or obliquely through them.

Suitable clips

42, 43, 44 and. 45, constructed in accordance with the present invention, may be put in place by first passing them, by means of the opening in the rearwardly extending flange, through the studding and then turning the clips so that the central web extends at a right angle to the strands of the studding, thus bending the bend-able tongue 20 and possibly also tongue 2|, depending upon whether or not there is any overlap at that point. If all tongues are bendable, they will bend accordingly. As shown, there WOllld'bE no overlap near the lower end of the drawing. -The clip is then moved downwardly along the studding until the downwardly extending channel engages the upper edge portions of the lowermost set of plaster boards 4|. Thereafter a second row of plaster boards is put in place, the lower edges thereof being forced into the upwardly extending channels of the already affixed clips, whereupon a second row of clips 42', 43, 44 and 45 is put in place in exactly the same manner as already described and a further rowof plaster boards supplied, etc., until the wall has been erected to the desired height. Wherever there is an overlap of the strands of the studding, clips having the configuration shown in Fig. 2 are employed, these having two bendable tongues 20 and 2|. It will be seen, however, that for most purposes it suffices to have available merely a clip as shown in Fig. 2, in which case the tongue 2| merely performs the function of the lug 25, with which it might just as well have been made integrally instead of separated by a slit. In either event, the clip is tightly held to the strands and because of the abutment of the tongue 22, after being once in place, is relatively difficult to slide up or down on the studs, the rib 23 on the tongue serving to give a sort of bite to the tongue.

After all the members have been put in place, plaster of any suitable kind may then be applied thereto and the wall then completed in the usual fashion.

It Will be readily appreciated that this structure provides a substantially fireproof construction if the boards are of incombustible material or a fire-retarding wall if the boards consist of combustible or a combination of combustible and incombustible materials. If the boards consist of ceramic plates, then the entire structure is substantially fireproof, which would also be the case if the plates consisted entirely of cementitious material such as Portland cement or set gypsum. In the particular construction illustrated in Fig. 8, the boards consist of perforated plaster having outer layers of paper, these boards being provided with holes 50 through which some of the plaster applied can pass in order to form interlocking buttons or keys. This type of construction is quite highly fire resistant by virtue of the fact that should a fire occur and the plaster as well as the plaster of the boards become calcined by the heat, relatively thicker and rearwardly extending buttons will be protected against calcination by reason of their thickness and thus will retain sufficient strength to hold the plaster onto the wall, preventing the fire from breaking through the wall into the next adjacent space or room.

The provision of the rib l2 on the central body portion ll of the clip is considered to be an important feature of the invention and is broadly new, as is also the provision of the combination of bendable and relatively unbendable tongue portions in th flange F.
