TIE BRACKET Original Filed April 30, 1930 ZOZZZG 211 3602260 M $841.,

Patented Jan. 30, 1934 UNITED STATES PATENT OFFICE TIE BRACKET Louis C. Piazza, Western Springs, 111., assignor to Soundex Corporation, Chicago, 111., a corporation of Illinois 6 Claims. (01. 72-103) This application is a continuation of a pending application, Serial No. 448,466, filed April 30, 1930, and relates to tie brackets, more especially to such tie brackets as are particularly applicable for tying together two spaced wall parts that constitute a mold for a filler of concrete or the like.

I propose to make building walls of an outer section of stucco laid on metal lath, an inner wall section of insulating slabs, and between the two a load sustaining filler of concrete or the like. The insulating slab section and the opposite metal lath section constitute a permanent form or mold for the concrete, and are tied together in spaced relationship by novel tie brackets which constitute the present invention.

It is one of the objects of the present invention to provide a simple and economical tie bracket which may be easily inserted in place during the building of the wall. It is a further object of the present invention to provide a tie bracket which will serve to hold two adjacent insulating slabs together in addition to tying the two wall sections together. I accomplish this end by providing a bracket having a horizontal portion extending between the two walls and provided with projections at its free end. for embedding the same into the insulating building slabs. At its opposite end the horizontal portion of the tie bracket is provided with a vertical portion which may be tied or otherwise secured to the wire lath.

I have discovered that there is another factor of considerable importance that must be taken into consideration in the design of a. tie bracket such as is here contemplated. Where a thin coating of plaster or the like is to be applied to one of the wall surfaces it is desirable that there be no contact or bond between the bracket and the plaster. This is important because should there be rusting of the protruding end of the bracket that is in contact with the plaster the increase in volume of the metal, due to the rusting, may be sufficient to spall the plaster. I overcome this objectionable feature by providing a bracket that does not protrude beyond the outer surface of the insulating slab. My tie bracket is secured to the insulating slab intermediate the ends thereof by the use of double ended nails or by the provision of pointed projections formed integrally with the bracket and adapted to be embedded in the slabs.

The attainment of the above and further object of the present invention will be apparent from the following specification taken in conjunction with the accompanying drawing forming a part thereof.

Reference may now be had more particularly to Figures 1 and 2 showing a fragmentary portion of a wall constructed in accordance with the principles of my invention. In this embodiment the wall comprises one portion indicated at 1 formed of insulating slabs, as shown at 2, 3 and 4. These slabs are generally rectangular and about 2" thick, the sides being about 16" by 48", although it is to be understood that theinvention is not limited to the use of a slab of this size as the slab may be made of any size desired. The slabs are heat insulating and are preferably, although not necessarily, formed of long fibrous material, such as excelsior or the like, promiscuously intertwined and held together by a suitable binder. A method of making such slabs is shown use of slabs made by a process such as is referred to in the above application. It is only essential that the slabs used shall have a surface texture of such a character as to cause it to adhere to concrete rather than to part from it.

In the slab shown the fibers are loosely and promiscuously intertwined so that the surface of the slab has a large number of interstices into which concrete or the like may enter. The slabs 2, 3, and 4 are built up to form a wall, said slabs being laid with the ends in adjacent rows staggered in the same manner that the bricks are laid. A metal lath 6 is mounted in spaced parallel relationship to the wall portion 1. The metal lath 6 is held in position in spaced relationship to the wall portion 1 by means of tie clips or brackets 8 that are secured to the wall portion 1 and to the metal lath. The bracket shown may be L shaped and comprise a horizontal portion 10 and a vertical portion 11. The tie clip or bracket may be of a construction such as is shown more particularly in Figures 3 to 7. The form of bracket shown in Figures3 and 4 is an L shaped channel section and is formed of metal. The flanges of the channel are cut away adjacent the end of the horizontal portion 10 as indicated at 15, and the end of the base portion is slit centrally for a short distance and the opposite end bent in opposite directions, as indicated at 17 and 18. The ends 1'? and 18 are pointed to facilitate their insertion into a slab in the same manner that a nail is inserted into a yielding object. The tie clips or brackets 8 may be arranged in vertical alignment with adjacent vertically aligned brackets secured together. This is illustrated in Figure 3.

The flanges of the channel of the vertical portion 11 of the bracket are forced outward slightly, thus permitting the insertion of the base of another bracket into the same. This is illustrated at Figures 3 and 4. The flanges of the two channels that have been inserted into one another are then bent inward, thus crimping the two together. In addition the portion 11 of the bracket has a number of holes 20 formed therein in spaced relationship. The holes in the two brackets are brought together and then the brackets may be secured by means of a wire or the like. The dis- -tance from the ends 15 of the flanges to the pointed portions 1'7 and 18 is equal to one-half of the thickness of an insulating slab, and the bracket is brought against the slab with the point 18 at the center of a slab. The point 18 is then forced into the slab with the point 1'7 extending upward. Another slab is then brought down above the first slab and upon being forced downward the end 17 enters the center of the bottom portion of that slab. The portions 15 of the flanges bear against the inner sides of the slabs.

The vertical portion 11 of the tie bracket is secured to the metal lath 6 in any desired manner.

The channel may be of such a small cross-secthe concrete rigidly unites itself to the insulating slab because of the large number of small interstices in the slab. Likewise the concrete firmly embeds itself in the metal lath due to the large number of small openings in the lath. It is to be noted that the bracket ties do not come into contact with the facing materials that may be placed on the outer side of the Wall 1, but are driven into the center of the slab. This effectively prevents any possibility of condensation at the end of the tie bracket.

Reference may now be had to Figures 5 and 6 showing a portion of a modified form of bracket which in general is similar to that shown in Figure 3. The bracket is channel shaped, as shown in Figure 3, and at its back portion 11 has a number of stamping or punchings 25 formed therein. These permit the ready securing of the tie bracket to the metal lath since the expanded portions 25 may be forced into adjacent openings in the lath and then upon moving the bracket downward it becomes rigidly secured to the lath. In other detail this bracket may be the same as that shown in Figures 3 and 4.

Figure 7 shows still another form of a bracket which is of small L shaped cross-section. Otherwise this bracket is essentially similar to that shown in Figures 3 and 4. This bracket has a number of holes 28 formed at the corner of its vertical portion 11 for facilitating the securing of adjacent brackets together. These holes correspond in function to the holes 20 of Figure 3. The base portion 10 of this bracket has a downwardly formed stamping 30 formed therein and an upwardly formed stamping 31 also formed therein. At the end of the bracket is formed a nail hole 32. The distance between the center of the nail hole and the portion 30 is equal to about one-half of the thickness of an insulating slab. When this bracket is used the portion 35 is rested upon the top part of an insulating slab with the portion 30 thereof resting against the side of the slab. A nail may then be driven through the hole 32 to rigidly secure the bracket to the top of the slab. The upper end of portion 31 is pointed in order to enable the same to readily embed itself in an insulating slab that is mounted on top of the slab whereon the bracket rests. L shaped bracket is flattened in order to provide a greater surface area for the portion 30 and the portion 31.

It is to be noted that the end of the p This bracket is U shaped rather apart by a vertical portion 42 which is of a height exactly equal to the height of one of the insulating slabs, and the prong 45 extends into the bottom of one of the slabs and the prong 46 extends intothe top of that same slab. In addition this clip is provided with a lower prong 48 which extends into the slab below that into which the prong 45 is embedded and the clip is provided with a prong 49 that extends into the slab above that into which the prong 46 is inserted. In other detail this bracket may be the same as that shown in any of the other Figures. When a bracket, such as is shown in Figure 8, is used then the brackets are not mounted in vertical alignment but rather they are staggered and therefore it is not necessary to secure together two vertically spaced brackets.

Stucco, brick veneer, stone, or other material may be applied to the outer side of the wall in order to improve its appearance. Likewise plaster or the like may be applied to the inner side of the wall. This is indicated, in connection with the metal lath 6, at 50.

In Figure 9 there is shown still another form of wall tie bracket which may be used in a wall construction such as is shown in Figures 1 and 2. This bracket is formed of a bar of metal having a generally V-shaped cross-section and bent into an L shape. The vertical leg 60 of the bracket is secured to the metal lath in any preferred manner. For instance, it may be tied thereto at a plurality of spaced points along its length by means of tie wires. The horizontal leg 61 extends from the metal lath to the insulating slab and is flexed at the end as indicated at 62. The flexed end is provided with one or more spaced holes as indicated at 63 and 64 to facilitate the securing of the bracket to the insulating slab. The flexed end 62 of the bracket is placed between two adjacent slabs of insulating material in the manner shown in Figure 2 and is secured to both of the slabs by means of a double ended nail such as is shown in Figure 10. The flat end 62 is placed on top of one slab and the long end 66 of the nail shown in Figure 10 is driven through the opening 63 in the tie bracket until the flat portion 67 of the nail abuts against the tie bracket. The short end 68 of the nail projects upward from the flattened portion 62 of the bracket and a second insulating slab may be brought down on top of the first one, said portion 68 of the nail entering into the upper slab and thereby securing the two slabs together. Where two nails are used the second nail may, if desired, be reversed so that its short end 68 extends downwardly and its long end 66 extends upwardly. This, of course, is optional. This form of tie bracket is preferable to the brackets previously described in that it is cheaper to make and the amount of labor involved in setting the same up on the job is also less than that involved in connection with the use of the other bracket here shown.

In compliance with the requirements of the patent statutes we have herein shown and described a few preferred embodiments of our invention. It is however, to be understood that the invention is not limited to the precise construction herein set forth, the same being merely illustrative.
