REVERSIBLE WALL TIE Filed O'Cb. 17, 1963 3,292,336 REVERSIBLE WALL TIE Wilfred Brynjolfsson and William H. Bartlett, Cedar Rapids,.lowa, assignors to D'ur-O-Wal National, Inc., a corporation of Iowa Filed Oct. 17, 1963, Ser. No. 317,003 6 Claims. (Cl. 52-713) This application relates to masonry wall construction land more particularly to a means for tying two walls of premolded elements together to form a single cavity wall unit.

In conventional cavity wall construction wherein two spaced generally wythes formed of premolded elements suc has concrete block or the like are held together by cementing means such as mortar or the like, wall tying means are generally used to tie the two wythes together as a unit. Generally the Wall tying means includes two members positioned -in Ithe cementing material between the horizontal courses of each wythe and adapted for selective secu-rement. Typically these wall tying means are adapted for mutual seourement even though the plane of the cementing material 'of the respective wythes in which each member is lodged is above or below that of the mating member. Genenally one of the wall tying members. is embedded in the first wythe and when the second wythe is being constructed, the second member is thence secured to `the iirst tying member in an appropriate manner depending upon whether the second member will fbe positioned in a plane above or below that of the rst member. However, since two separate members are used the possibility of loss of the second member is ever present. Also, after the lirst member has been appropriately embedded in a mortar course the second mating member must be carried or stored somewhere else which may prove an inconvenience to the worker.

It is further typical of these wall tying means to be provided with some sort of a notch or recess in the horizontal plane of the one of the elements of lthe members to serve as a drip notch for collecting moisture which may collect in the cavity between the wythes. Typically such a notch is formed in the male member but since it cannot be predetermined whether the male member will be positioned at a lower level than the female member with its male element projecting upward or vice versa, then such `a notch must be -formed twice so as to compensate for the possible reverse positions of .the male member. This double formation of such a notch necessarily involves an added step and added expense in the production of wall ties.

It is therefore a primary object of this invention to provide a new and improved wall tie means.

It is another object of this invention to provide a new and improved wall .tieV means which is free from the objections mentioned above.

It is still another object of this invention to provide a new and improved wall tie means wherein the male ends and :female members are permanently secured prior to emplacement in a mortar course.

It is yet another object of this invention to provide a new and improved wall tie wherein the male and female members are permanently secured prior to emplacement in a mortar course and the nonemplaced member either above or therebelow for emplacement in a horizontally extending morta-r course in a mating wythe of a cavity wall.

It is yet another object of this invention to provide a new and improved wall tie wherein the male and female members are secured together prior to the emplacement of either of the members in the mortar course of a concrete block wall and wherein the male member is adapted United States Patent O 3,292,336 Patented Dec. 20, 1966 ice to provide la drip notch means as an integral part off the male element thereof.

Other objects, features and advantages of the present invention will be apparent from the following description of the preferred embodiment illustrated in the accompanying drawings, in which:

FIGURE l is a perspective view of .a cavity Wall showing the use of the wall tie embodying this invention;

FIGURE 2 is an enlarged perspective view of the wall tie of this invention;

FIGURE 3 is a fragmentary top plan view of a portion of a cavity wall showing the position of the wall tie of this invention therein;

FIGIURE 4 is another fragmentary top plan view similar to FIGURE 3 showing the wall tie therein with the male and female members turned about from the position shown in lFIGURE 3;

FIGURE 5 is a section view taken along the line 5-5 of FIGURE 3 wherein the female member is emplaced in a mortar course slightly below the plane of the mortar course in which the male member is emplaced; and

FIGURE '6 is a section view taken along the line 6 6 of FIGURE 4 wherein the male member land female mem-ber are turned about from their position shown in FIGURES 3 :and 5 and also the Ifemale member is positioned in the mortar course in a plane above the mortar course in which the male member is emplaced.

In FIGURE l, the wall tie 10 of this invention is shown in use in -a cavity-type wall 12 consisting of a pair of wythes 14 and 16 having -a space or cavity 18 therebetween. The wythes 14 and 16 are made of conventional premolded material 19 such as concrete blocks or the like `and are secured together by suitable bonding or cementing means 20 such as mortar or the like. The fblocks are built in horizontal layers, or courses, 21 wherein the individual blocks 19 are vertically misaligned relative to the next horizontal layer thereabove or therebelow and in vertical alignment with the individual blocks of the layers of the second layer above or below in typical block or brick wall Iconstruction fashion.

Thewall tie 10 comprises a male member 22 and a female member 23 `both made of relatively heavy wire stock metal. The Afemale member is substantially L- shaped in plan having a base 24 and a transversely extending arm 26 which is bent upon itself :at the free end thereof .to -form `an eye or female element 218. The female element is adapted to be emplaced in the mortar course `of a concrete block wall so that the base thereof is substantially parallel to the mortar course and the arm extends generally perpendicularly outward therefrom to position the eye 28 in the space 18 between the wythes with the opening thereof in a generally vertical plane relative to the longitudinal extent of the wythe.

The male member is bent upon itself to form an elongate loop 30 having on the free side thereof a iinger or male element 32 sharply turned at either end 34 or 36 to form the opposite generally parallel half side members 38 and 40 which substantially close the loop. The side members are slightly misaligned in a vertical plane and at their point of lateral juxtaposition where they close the loop they are b ent outwardly substantially transverse to the plane of the loop. This outward bend of each of the side members forms the two substantially coextensive arms 42 and 44 which are sharply bent away from each other in a direction generally transverse thereto to form the substantially colinear oppositely extending base members 46 and 48, respectively. The base members also occupy the same plane Ias the arm members and are also in a plane transverse to that of the loop. The female member is secured to the male member with the linger of the latter extending through the eye of the former.

In use the wall tie may be positioned with either one of the members, preferably the male member, rst emplaced in the mortar course of one of the wythes 14 or 16. Since the members are secured together as a unit by means of a linger inserted through the eye of the female member, they are movable relative to each other. Thus if the male member is first emplaced in the cementing material of a wythe with the base members and arms thereof in a plane substantially horizontal to that of the cementing material the loop thereof may extend into the space `between the wythes so that the length of the loop, and therefore the finger, is substantially parallel to the vertical dimension of the wall. 'I'his will permit the freely banging female member to be positioned in selective horizontal planes above or below that of the male member` depending upon the position of the mortar course of the companion wythe into which the female member will be placed. During construction of the wall, once the male member is emplaced in the mortar of one of the wythes, there is no need to carry around or store the mating female member. Also, as evidenced by FIGURES 5 and 7 there is no top or bottom end of the male member since it may be turned about in its position so that either of the sharply turned ends 34 and 36 serve as a drip notch for collecting moisture which may seep in or collect in the space 18.

This invention provides a wall tie wherein the -male and female members are presecured as a unit prior to emplacement in the cementing material of a concrete block wall. One of the members may be emplaced in the mortar course of a wythe and the other permitted to hang freely therefrom until the companion mortar course iscompleted in the related wythe of a cavity wall. Furthermore, with the wall tie of this invention, regardless of the positioning of the male member, there is an integral drip notch formed therewith.

While we have shown and described certain embodiments of our invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of our invention as set out in the appended claims.
