United States Patent 3,293,810 COMBINATION WALL TIE, DRAFT STOP AND DRAINAGE MEANS FOR WALL CONSTRUC- TIONS Monroe J. Cox, 2191 Berringer Ave., Louisville, Ky. 40204, and William J. Steier, Jr., 2212 Sieger Villa, Louisville, Ky. 40218 Filed May 22, 1964, Ser. No. 369,381 6 Claims. (Cl. 52-303) This invention relates to a wall tie construction employed in buildings, and particularly those buildings wherein there is supplied an outer wall of masonry and an interior frame wall-this building construction being of the type known as brick veneer, and the present apparatus being mounted between the inner frame wall and the outer masonry wall.

The present invention comprehends a construction wherein there is provided a wall comprising an interior frame wall and anouter wall, and a tie means extended between the outer and inner walls. The tie means hereof has a three fold basic objective including the provision of a connection means for securing the outer wall to the inner wall; the provision of an effective fire stop means between the walls; and the provision of a flashing which prevents water from gravitating into the basement or lower area between the walls and aids in the expulsion of water from the area between the walls.

An object of this invention resides in the provision of an effective tie means secured to an inner wall and embedded in an outer wall to space the walls from one another and to aid in maintaining the outer wall in place.

Another object of significance resides in the provision of a metallic barrier means positioned between spaced apart walls, whereby updraft air currents between the walls are reduced or eliminated, the barrier further serving as a fire stop means.

A still further object is to provide a waterproof barrier means between spaced apart walls, and channel means in association therewith serving to effectively exclude the passage of water and to vent the water to the outside of the building.

Other and further objects and advantages of the invention will become apparent to those skilled in the art from a consideration of the following specification when read in conjuntcion with the annexed drawing, in which:

FIGURE 1 is a fragmentary perspective View of a section of wall construction with a wall tie constructed and assembled in accordance with the teachings of this invention in place, the construction being shown in section at one end;

FIGURE 2 is an enlarged, fragmentary, disassembled perspective view of the wall tie assembly hereof;

FIGURE 3 is an enlarged, detail sectional view of the wall construction; and

FIGURE 4 is a further enlarged, fragmentary perspective view showing a modified form of tie member.

Referring to the drawing in more detail, the tie member of this invention is shown in a first form in FIGURES 1 to 3 and is therein identified by reference numeral 10. The tie members find a preferred environment of use in a building construction 12 which includes a footing 14 on which is provided an interior frame wall 16, including a vertically arranged, flat outer member 18, and an outwardly spaced masonry wall 20. The wall 20 includes rows of bricks 22, and layers of mortar 24 between the rows and the individual bricks. This type of wall construction is per se conventional, and is often referred to as brick veneer.

To rigidify the wall, support and connect the outer wall 20 to the inner wall 16, provide a fire barrier be- 'ice tween the walls, and provide a water barrier therebetween, the tie members 10 of this invention are provided in an end-to-end string between the walls 16 and 20, preferably above ground level.

The tie members individually comprise an'elongated, substantially L-shaped body portion 26 which includes an elongated, substantially rectangular back member 28 and an outwardly directed, substantially rectangular, perpendicularly related foot member 30. The foot member has a forward end edge 32, and the body portion 26 includes sides 34 and 36 (FIGURE 2) with opposite, rebent flanges 38 and 40 thereon whereby the members are adapted for connection in end-to-end relation. As shown, one of such flanges may be inwardly bent from the general flatwise plane of the members 26 and 28, as at 42, to insure alignment of the body portions. As seen in FIG URES 1 and 3, the back members 28 are secured to the wall member 18 by nails 44, with the foot members 30 thereof projecting outwardly toward the outer wall 20.

Extending from the edges 32 of the foot members 30 at spaced locations is a plurality of connection plates 46. The plates 46 are of a depth substantially equal to the thickness of the outer wall, .and are corrugated laterally having plural ridges and grooves 48 and 50, respectively. The connection plates are embedded in one of the layers of mortar 24, which hardens in the grooves 48 to form a plurality of mortar ridges and grooves interlocking with the plate ridges and grooves.

The tie members further include drainage plates 52 projecting outwardly from the edge 32 of the foot members 30 at spaced locations. The plates 52 are substantially flat, and have a central, downwardly struck trough or channel 54 extending, as seen in FIGURE 3, into the foot member 30. The plates 52 are embedded in the mortar 24, but an opening in the mortar or weep hole 56 is provided therein above the trough 54. Thus, any water collecting on the foot member 30 is drained outwardly of the building through the trough 54 and hole 56.

In FIGURE 4, a modified construction is shown, comprising a tie member 10a with a body portion 26a including a back member 28a merged with a foot member 30a at an arcuate connecting portion 100. The tie members 10a have rebent flange means 38a, for end-to-end connection thereof, and also have projecting connection plates 46a and drainage plates 52a. Due to the arcuate form of the connecting portion 100, improved drainage to the troughs 54a is provided.

As will be noted in FIGURE 1, when'in place the foot members 26 or 26a extend fully across the space between the vertical wall members 16 and the outer wall 20. Thus, updraft air currents between the walls are prevented thereby reducing the likelihood of fire spreading between the walls and acting as a block to the possible spread of flame therebetween. Further, the passage of water is effectively precluded, and any water entering the walls is directed outwardly. Finally, the outer wall is supported in spaced relation to the wall 16.

Having described and illustrated two embodiments of this invention in some detail, it will be understood that these descriptions and illustrations are offered merely by way of example, and that the invention is to be limited in scope only by the appended claims.
