Description
2~2~ao FIELD OF TH~ lNV~.. rION
This invention qenerally relates to support brackets used in the construction industry and more particularly relates to a lateral ~upport clip for stabilizing a thick wall.
RAr~ouND OF ~ INV~N 110N
In this patent specification, the term "thick wall~ is used to refer to a wall which has some structural rigidity, such as a block wall, as distinguished from a 10 Npartition-type n wall such as one of drywall construction.
A thick wall typically has a thicknes~ of 3 1/2 or more inches. It is to be understood that the term ~thick wall"
is intended to include similar section~ such as a window mullion.
In the construction industry, when a thick wall is being erected between a floor and a ceiling, it is necessary to provide lateral support at the top of the wall. Such lateral support may be provided by securing the top edge of the wall to an adjacent ceiling or structural member. Various brackets or clips have been devised for achieving such a connection.
One of the prior devices comprises a generally F
shaped clip which is placed over the upper course of blocks with each arm of the F on opposite sides of the block and the tail projecting away from one of the sides. Once the block has been laid, a suitable fastener is then used to 20203~0 attach the tail of the clip to the surface which is to provide lateral support. The attachment means selected depends on the nature of the supporting surface. Common attachment means include bolting, screwing, welding and S explosive-charge driven fasteners.
Prior F shaped clips of the type described above have been manufactured from two pieces of ~heet metal or metal plate. One of the piece~ i8 bent at right angles to define the back of the F and the upper arm. The other piece is then welded at right angles to the back of the F
to form the other arm. Disadvantages with such cl ip8 include high manufacturing costs, heat distortion during welding and handling difficulties. The manufacturing costs result from the complexity of the manufacturing process which includes ~oining two components by means of welding.
The handling difficulties stem from the shape of the clips preventing stacking in such a manner as to minimize the space taken by the clips.
It will be appreciated that handling difficulties are exacerbated as the overall size of the clip increases.
While a number of relatively small clips may readily be packaged in a box or the like, larger clips require considerably more space and packaging becomes quite a problem. The prior art clips occupy a fair volume and require a relatively large container to store a relatively small number of clips. As typical construction codes require that such clips be spaced at rather frequent intervals along a wall, the volume of space occupied by the packaged clips is quite significant and reflects on handling, storage and shipping costs.
SUMMARY 0~ THÆ INVENTION
A clip is provided for stabilizing a thick wall, the clip comprises:

2~203ao D13SCRIPTION OP' PR~FERRED EMBODIllENTS OF l~IE PRESENT
IN V~I. . ION
Fig. 1 shows a clip, indicated generally by reference lO, having a generally F shaped profile S surmounting the top edge 12 of a wall 14 comprised of blocks 16. Securing meanq, such as a fastener 18, secure the clip lO to a securing surface, namely the underside 20 of a concrete slab 22.
Fig. 2 shows a prior art clip having first and second arms, 30 and 32 respectively, extending generally at right angles from a back 34. The second arm 32 extends across the full width of the back 34 and is attached thereto by a stitch weld running therebetween at 36.
Fig. 3 shows a clip 50 according to the present invention. The clip 50 has a generally plansr rectangular base 52 having a free end 54. First and second flange~, 56 and 58 respectively, are integral with the base 52 and extend generally at right angles thereto. The second flange 58 is intermediate the first flange 56 and the free end 54 of the base 52. The base 52 has a generally rectangular aperture 60 extending away from the second flange 58. The aperture 60 has a width greater than the width of the second flange 58. Although in most cases the flanges would be perpendicular to the base, it will be appreciated that this is not a necessary requirement. In a different arrangement the flange may be bent to other 202~300 -than a perpendicular angle relative to the base with both flanges nonetheless being generally parallel to each other.
Fig. 4 shows a blank 70 from which a clip such as the clip 50 in Figure 3 may be formed. The blank 70 may be formed from metal using conventional metal forming techniques such as cutting or stamping to the desired length and width. The blank is bent generally at right angles along the dashed line 72 to form a first flange such as 56 in Fig. 3. The blank i8 slit at 74 to form a generally C-shaped aperture having a tongue 76 therein.
The tongue 76 is bent along the dashed line 78 to form a second flange such as 58 in Fig. 3. The first and second flan~es, 56 and 58 respectively, are formed 80 as to be generally parallel to each other and spaced by an amount generally equal to the thickness of the wall to be supported by the clip 50.
It will be appreciated that as the cl$p 50 has an aperture 60 wider than the second flange 58, it is possible to stack a series of clips 50 one above the other as illustrated in Fig. 5. Clip 50a having a first flange 58a, a second flange 56a and an aperture 60a, is shown placed on a second clip 50b having a second flange 58b extending through the aperture 60a in the first clip 50a.
References 60b and 56b respectively denote the aperture and first flange of the second clip 50b.
Figure 6 shows an alternate embodiment of a clip according to the present invention wherein both the first 2Q20~00 flange 56a and the second flange 58a have been formed by bending from a slit portion of the base 50. Such slitting and bending to form the first flange 56a results in a first aperture 60a extending from the first flange 56a toward the second flange 58 and a second aperture 60b extending from the second flange 58 toward the free énd 54a of the base 50a. As such a clip would have a tab 78 extending from the base away from the first flange 56a and the first aperture 60a, it would typically be used for partition type walls or the like rather than outside walls and may be secured on both sides of such a wall.
In stacking the clip of Fig. 6, the first and second flanges, 56a and 58a of an overlying clip would be respectively received within the first and second apertures 60a and 60b of an underlying clip. To maximize stackability of a clip according to this alternate embodiment, the length of the apertures should correspond to the length of the flanges.
The clip may be provided with a mounting hole such as indicated at reference 62 through which a fastener may be inserted. Such a hole i8 not neceqsary when using an explosive rharge driven fastener.
Suitable results have been obtained using clips manufactured from 12 or 14 gauge galvanized metal secured using two Hilti ttrade mark) or similar fasteners. To ensure that the first and second flanges, 56 and 58, have generally the same strength, the width of the second 20~0300 ~., g flange should be approximately the same a~ the total width of the two strips of material on either Qide of the aperture 60. Various widths however may be used.
Typically the width of the second flange 58 would vary from 5 25 to 75% of the width of the first flange 56. Suitable results have been obtained u~ing clips having a flange length of from 2" to 2 1/2 n Preferably the distance between the first and second flanges, 56 and 58 respectively, should be approximately 1/8" greater than the 10 thickness of the wall to be supported Accordingly, this distance might be 3 5/8, 5 5/8", 7 5/8 n 9 5/8' or 11 5/8 for 3 1/2 n ~ 5 1/2", 7 1/2"or 11 1/2 blocks respectively.
Variations to the clip de~cribed above may be apparent to persons skilled in the art of forming such 15 clips without departing from the ~pirit and scope of the present invention. Such variations may arise in adapting the clip to particular walls or adapting the manufacturing technique to specific material~. For example, if galvanized metal is used the radius of the bends should be 20 great enough to ensure that the galvanized finish is not cracked ad~acent the bend. Furthermore, materials other than metal might be used for the clip in appropriate circumstances, for example plastic might be used with suitable modifications being made to the manufacturing 25 process such as extrusion rather than bending.
This invention qenerally relates to support brackets used in the construction industry and more particularly relates to a lateral ~upport clip for stabilizing a thick wall.
