New York, N. Y., assignors-toarclay Manufacturing Co., inc., Eronx, N. Y., a corporation of New York Application March 16, 1953, Serial No. 342,386 4Claims. (Cii20'-74) rfhis invention relates to improvements in the construction cf'building walls, particularly interior walls, and more especially to an improved corner construction for such walls.
The general object of theinvention is to provide an im proved corner construction 1for. walls made from prefabricated wall units or panels.
In the construction of walls from prefabricated units, difficulty has been experienced at' ther corners where two wall sections come together, and' particularly projecting corners, that is to say, where the two sections come together to form a corner whose" outside angle between the walls is` 270. The two wall units meeting at the corner usually can be made to approach into fairly close proximity to one another, but an open. joint remains which is both unsightly and neither moistureproof nor soundproof. The present invention attacks this problem and provides a corner molding which is readily assembled between the proximate edges of the two corner wall units, and which provides a soundproof and moistureproof joint between the units. `it also serves asI a protection for the corner gives it aneat'andj attractive appearance.
A further object of the invention is to provide such a molding which willl afford both a soundproof and moistureproof joint between the units without the use of a calking compound, or the like, and' which at the same time, will provide for` expansion' andV contraction of the wall corner units both vertically and horizontally, without affecting the tightness of the joint.
The invention will beI understood by considering the accompanying drawings andthe detailed description following. ln these drawings:
Fig. l is a View in horizontal section taken `on line 1`1 of Fig. 5 showing a projecting corner wall construction according to the present invention;
Fig, 2 is a perspective view illustrating one of the xtures or spring clips used in mounting the wall units on the wall supports or studding;
Fig. 3 is a perspective View of the improved corner molding;
Fig. 4 is a plan view offa complete wall unit; and
5 is a view in elevation looking from the right of Fig. l, as
of the wall being shown broken. away.
Referring now to these drawings and first to Fig. 4, the wall unit from which the two wall sections are constructed, as shown, comprises a body member 1 and'a" facing sheet 2 which are bonded permanently/together by meansof a layer The body member 1 has a portion 4i which extends to facing sheet Z, and the facing sheet has' a portion 5` which proiectsto-the leftxoverhangingatlie' left edge of body member i. if desired, however, the.` wall unit may be made in one piece. Along the right-hand edge of facing sheet 2 thereis a recesso formed in the'adjacent surface of thebody extension" 4; andiseated and secured by adhesive'in this recess thereis a molding strip' 7. This is made of flexibleresilientmaterial, and has oppositely projecting wing portions 8'and-9" for assisting in making a tight joint between the.` edges'` of: the facing sheets 2 of contiguous wall units, as showmin Fig. 1.
is of a composite construction and the right beyondthe edge of the nitcd States Patent:V
i end.
The body member 1, in the composite construction shown, is preferably about three eighths of au inch thick and the facing sheet member 2 about one eighth of an inch (1/8) thick making the overall thickness of the unit approximately one hal-f of an inch (1/2" dimensions, however, can be varied to suit conditions. Advantageously the body member 1 is made of asphalt impregnated wood liber insulatngboard., although it can be made of plasterboard, asbestos `cement board,. plywood, or the so-called sawdust boards, and other mate'T rials of this general character. The facing sheet member 2` is preferably made of tempered compressed Wood tiberboard, but it can also be made of glass, or metal, or plastic, if desired. i
The facing sheet member 2 is preferably provided with a suitable finish coating 10; Advantageously coating 1t) is a synthetic baked enamel enamel made of alkyd and melamine resins, or modied alkyd melamine resins. Such coating, however, may consist of an air-dried paint. or of a sheet of suitable plastic material laminated to the surface of facing sheet member 2, or the coating 10 may consist of a suitable lacquer. It will be understood, however, that the surface of facing sheet 2 may be left unfinished, and the wall painted in the usual manner, after installation.
Wall sections 11. and 12 (Fig. 1) are constructed by assembling wall units similar to the typical wall unit just described and shown in Fig. 4, and the details of the manner in which these units are assembled are set forth in co-pending application No. 342,385, tiled March 16, 1953. This assembling will be referred to here as briefly as possible. Y
The respective wall units A, B, C, andfD forming the` wall construction of Fig. l are mountedon thestudding members 1.3, 14 and 15. Units A andlC are attached` to the studding by means of spring metal clips 16`(Fig. 2). These clips each have teeth angles from one end of the mid-section 16, and a shank` 18 projecting at right angles from the opposite end of the mid-section.
The spring clips are placed in spaced relation along one edge of the wall panels. The teeth 1'7" are forced or worked into the panels as shown at the lower right and upper left of Fig. l. u
The right-hand portion of the wall shown in Fig; 1
will be constructed first, and it willv beiassumed that the` wall has been finished up to and includingipanel A. This panel is held in position against the studv 13, and nails 2,0 are driven through `the holes of Shanks i8` of th'e spring clips. The panel section tion by forcing its body member facing sheet projection of the' .panel A. This compresses, or takes the bow out of the metal clips 16 attening the B is then placed in posi- Shanks` as shown in Fig.
l, and this spring action keeps the par-ts'tightL In forcingi these panels A and B together, the respective` Shanks of the clipsmay cut, or form, recesses or depressionsin the inner surface of the body member 1 of panelfB. Thetwo panels are worked together until the edge of the facing sheet 2 of panel B engages and somewhat compresses the resilient molding 7.
With panel B` in position itsopposite edge overlies the` facing sheet projection 5 of wall.
corner stud14 with the unit B preferably projecting beyond the surface 21; of stud 14.1 There is` some leeway in the relative location of these two parts which `is provided by the improved corner molding 22. This molding as shown in Fig. 3 comprises a thin base member 23 shown moreparticularlyin Fig. 1; Extending alongthe oppositev or thicker edge of base member 23 and at right angles is ashank portion 24. This shank portion ter- These such` for example as an 1-7 projecting at right Shank 18 has a nail hole 19 neariitslouter` projection 4 beneath the thespring shanks 1S off of considerable width andv advantageously tapering to a relatively thin edge as minates in twooppositely projecting wing portions 25 and 26 which are unsymmetrically arranged with respect to shank portion 24, These wing portions form, with shank portion 24 and base member 23, respectively, two recesses 28 and 30, recess 28 being substantially thinner than recess 30.
The molding is manufactured by a molding or extrusion process from a suitable flexible resilient material, which, advantageously, may be vinyl plastic. It also can be made of natural rubber, of synthetic rubber, such as neoprene, or combinations of these materials, or of any convenient material, which will provide the characteristics of flexibility and resiliency, particularly in the two wing portions 2S and 26. Before the molding is placed upon the wall, the wing portions 25 and 26 stand inwardly as indicated by the dotted lines in Fig. 3. The full line position of Fig. 3 corresponds with the positions of these portions as shown in Fig. 1.
The next operation is to mount the molding 22, andV this is done by driving nails 27 through the holes 27a which are provided in spaced relation along the base member 23. In placing the molding, the wing portion 25 will be forced 'outwardly v'from the normal dotted wing is slipped overy 'the facing vsheet projection 5 or unit B.v This'projection is receivedin the recess 28 formed between'the shank 24 and wing 25 which is now substantially parallel with the inner surface of shank 25. It will lbe understood that the pressure of wing 2S against projection will not onlyA form a tight soundproof and moisture'proof' joint from top to bottom of panel B, butv it also mechanically supports this edge o-f panel B against the Vsurface ofstu'd 14.
Continuing the 'Wall' construction'around the corner,
panel C is rst prepared for its application to studs v1'4 and by applying the spring clips 16, as previously described, and further by sawing 'off along the opposite edge of the panel the portion shown in dotted lines in Fig. 4. The portion removed includes the entire body projection 4, the molding 7 Aand a portion of the edge lof facing sheet 2 thereby leaving a iiat edge 29 which is at right angles to the face/s of the wall unit and forms square corners therewith.
Panel C thus prepared is placed with its square edge 29 withinthe recess v30 which is formed by the wing por-k tion 26 of molding 22 and its base member 23. In doing this the wing portion 26 is forced outwardly from its normal dotted position,as shown in Fig. 3, to substantially parallel position with base 23, as shown in Fig. 1. The pressure of wing 26 along the surface of facing sheet 2 of unit C forms a tight joint atA this point :from floor to ceiling, and also 'wing 25 'supports this edge of unit C against the surface of stud 14. The opposite or left-hand edge of unit C is now attached to stud 15 by means of nails 31 driven into the stud through the shanks of the respective spring clips.
In Fig. 1 the wall unit D is shown ready to4 have its body projection 4 forced over the outwardly positioned spring shank portions 18 of the spring clips and beneath the facing sheet projection 5 olf unit C. The arrow is intended to indicate this movement.
lBy means of the improved corner construction including the molding 22, not only is a tight joint formed which is both soundproof and moistureproof, but valso the adjacent edges of the two corner wall units B and C are irmly secured to the corner stud 14. In addition, however, and which is important, the construction of molding 22 aords a considerable degree of leeway in matching the sides of the wall units with the corner stud. For example, projection 5 of wall unit need not project clear to the bottom of its recess, a good seal is obtained if the projection is received onlyrpart way within this recess.
. of the base member at right angles thereto, a wing portion projecting from said shank portion and having an inner surface generally parallel with said shank, and a second wing portion projecting oppositely from said shank and having an inner surface generally parallel with said f base member, said wings being `supported entirely by said single shank portion.
2. A corner molding for a Wall construction having wallsupporting means, said molding comprising a single thin base member for attaching to the wall supporting n means., asingle shank portion extending along one edge posltion of Fig. 3 to thevposition of Fig. 1, whenv this of the b'asejmember at right angles thereto, a wing por tionprojecting from said shank portion and having an inner srfacegenerally'parallel with said shank, and a second wingportion projecting from said shank in the l oppositedi'rection and having an inner surface generally parallel with said base member, said wing portions being exible and resilient and being supported entirely by said single shank portion.
' 3. A corner wall'construction comprising wall supporting means, two wall units of the same thickness mounted on said supporting means at right angles to each other andl havingtheir edges in proximity to one another and forming a corner, one of said units having a projecting outer face portion overhanging the body portion thereof,
a cornerl molding disposed between the proximate edges of said wall units, said molding having a base member attached to said wall supporting means, a shank portion extending alongl one edge of the base member at right angles thereto, and two wing portions projecting oppositely from said shank portion, one of said wing portions being generally parallel with said shank and forming therewith a recess, said projecting face portion of one of said units being received therein, and the second of said .wing portions projecting generally parallel with said base memberand forming therewith a second recess for receiving the entire thickness of the second of said wall units.
4. A corner molding for a wall construction having wall supporting means, said molding comprising a single base member for attachment to said wall supporting means, a single shank portion extending along one edge of the base member at right angles thereto, and two wing portions projecting oppositely from said shank portion,
. one of said wing portions forming therewith a recess,
Also, tiexibility is possible in placing unitV C, inasmuch as the edge 29 may be sawed at any desired point along the width of this unit.
That is, for example, if required,
and the second of said wing portions forming with the base member a second recess, said wing portions each having a free edge and each being supported entirely by said single shank portion and being unsymmetrically arranged with respect to said shank whereby the central planes of vsaid recesses are disposed at right angles to one another.
