(Cl. 52-713) ABSTRACT OF THE DISCLOSURE Anchor formed of wire bent to define transverse legs adapted to be embedded in masonry wall, and loop having straight wire run, loop fitting into space between masonry and facing walls. Bracket formed of wire adapted to be embedded in facing wall, and having straight wire run for engagement with loop. Straight runs of ancho and bracket substantially perpendicular.

This invention relates to building wall construction, and in particular to means for anchoring an outer facing wall to an inner masonry wall.

In the construction of walls of buildings, it is wellknown practice to first construct an inner wall made of a masonry material, such as concrete blocks or poured concrete, to establish the core or shell of the building con-- struction, and then to construct a facing wall made of material such as brick or stone, which is spaced a relatively small distance from the masonry wall and stands substantially parallel to the inner masonry wall. The material of the facing wall provides an improved aesthetic appearance to the building. In this manner a wall construction is obtained which combines the strength of the concrete masonry structure, and the pleasing appearance provided by the outer facing wall. In such constructions it is necessary to provide means for anchoring the outer facing wall to the inner masonry wall. In many present constructions of the type described, one end of a metal strap is first imbedded in the masonry wall, and the free end of the strap is thereafter embedded in a joint of the facing wall. The free end of the strap is brought to the proper level of the facing wall joint by bending and manipulating the strap until the end of the strap extends at the level of the joint of the facing wall. This known anchoring means has serious disadvantages in that there is a tendency for the strap to fracture or break during the installation operation due to the stresses formed in the strap as a result of its being flexed. The straps also tend to fracture or twist out of shape after the construction of the wall, due to uneven settling of the inner and outer walls, causing the facing wall to be inadequately supported.

It is therefore a general object of this invention to provide a masonry anchor which overcomes the ditliculties referred to above.

It is a further object of the present invention to provide a masonry anchor made of a relatively light weight material and of simple construction which nevertheless provides sufficient support to retain the facing wall to the inner masonry wall.

It is another object of the present invention to provide a masonry anchor in which the elements to be imbedded "ice in the facing wall may be readily set at the proper level without weakening the structure of the anchor itself.

It is still another object of the present invention to provide an adjustable connection between the facing wall and the inner wall so that the facing wall will not crack or fail due to movement in the inner-wall which may be caused by settlement of the foundation, difference in the rates of expansion, or vibration caused by winds or earthquakes.

It is an important feature of the present invention that the anchoring members can readily be afilxed to at least one reinforcing rod which extends within a longitudinal joint along the length of the inner masonry wall, thereby producing simultaneously a reinforced wall construction and support between the masonry wall and the facing wall.

In accordance with the above mentioned objects, the invention provides a wire which is bent at one end to form a pair of oppositely directed trasverse legs which are adapted to be embedded within the masonry wall. At the other end, the Wire is provided With-a vertically elongated loop. When the transverse legs are placed in the masonry wall, the rectangular loop lies vertically within the spacing between the masonry and facing walls. A bracket which may be formed, for example of a length of wire bent in the shape of a rectangle or triangle, is: placed in freely engaging fashion within the loop so that the bracket may freely move vertically and horizontally with respect to the loop. A portion of the bracket is embedded in a joint of the facing wall, so that the engagement of the anchor and bracket prevent movement of the walls away from each other, but permit relative movement between the walls in their own planes.

It is also a feature of the present invention to make the height of the loop at least equal to the spacing between the building units, e.g., the bricks, of the facing wall, so that regardless of where the anchor is placed in the masonry wall, the bracket which is to be embedded in a joint in the facing wall can engage the loop.

In a further embodiment of this invention the wires extend normally from reinforcing rods which are disposed along the masonry wall to increase the strength and rigidity of the masonry wall. As in the embodiment mentioned above, the portion of the anchor extending from the masonry wall is formed into a loop with which the bracket to be imbedded into the facing wall is freely engaged in a manner to permit free vertical movement of the bracket within the loop so that the position of the bracket can be adjusted to line up with the joints in the facing wall.

Further objects and features of this invention will be apparent from the following complete detailed descrip tion which should be read in conjunction with the accompanying drawings.

With reference to the drawings, the masonry securing means of the present invention is formed from two elements such as those shown in FIGS. 1 and 2. An anchoring section 10 (FIG. 1) which is adapted to be partially embedded within the inner masonry wall, is formed from a relatively rigid wire which is given a bend 14 at each of its ends to form a pair of opposedly transverse legs 1-6. Intermediate the two ends of wire 12, the wire is given a succession of bends to form a substantially rectangular loop 18, connected to the legs 16 by a bridge section 12. The wire 12 is so bent that the plane in which the legs 16 is located is perpendicular to the plane which carries the loop 18.

A bracket (FIG. 2) is adapted to have one leg thereof in interlocking engagement with the inner periphery of loop 18 to permit free vertical movement of bracket 20 within loop 18 but to prevent movement of the bracket 20 away from (toward the left in FIGS. 3 and 4) the anchor 10. In the embodiment of FIG. 2, bracket 20 is substantially rectangular in form and has an opening 22 provided in one of the legs of the bracket by means of which bracket 20 may be interengaged with the vertical leg of loop 18. In FIG. 6 there is shown another possible configuration of a bracket which is designated by reference numeral 20'. Bracket 20' is a wire bent to have a substantially triangular form and has a slightly rounded apex which engages the inner periphery of loop 18. An opening 22 is formed in one leg of the triangle by means of which bracket 20' is loosely interlocked with loop 18 for free vertical movement along the loop 18.

With reference now to FIGS. 3, 4 and 5, there is shown a typical masonry wall construction of a type utilizing a masonry anchor such as that of the present invention. The wall construction is formed of an inner masonry wall 24 which has spaced in front of it an outer facing wall 26. Masonry wall 24 is constructed of a number of construction units such as concrete blocks 28 which are joined together at joints 30. Joints 30 are filled with a suitable bonding material, such as mortar or cement. Similarly, facing wall 26 is constructed of individual building units 32, which may be brick or stones. The joints 34 between the bricks or stones 32 are also filled with mortar or other suitable bonding material. As may be seen in FIG. 3, the portion of anchoring section 10 which extends rearwardly from loop 18, including the bridge section 12 and the transverse legs 16, is embedded in one of the horizontal joints 30 between two vertically aligned concrete blocks 28 of masonry wall 24. Loop 18 is therefore disposed within the spacing between masonry wall 24 and the outer facing wall 26. It is a feature of this invention to make the vertical dimension of loop 18 about equal to the vertical dimension of one building element 32 plus one joint 34 of facing wall 26. In this way, regardless of the degree to which the horizontal joints 30 and 34 are out of horizontal alignment, a portion of the loop 18 will always be horizontally aligned with one of the joints 34 in the facing wall.

As shown in FIGS. 3 and 5, bracket 20 is adapted to be at least partially embedded within a horizontal joint 34 of facing wall 26. Before embedding the bracket, it is interlocked with the loop 18 of anchor 10, which is already secured in the previously erected inner wall 24. The level of the bracket 20 is then set to correspond to the level of joint 34 by merely moving bracket 20 vertically along loop 18 until the bracket 20 is horizontally aligned with a joint 34 in the facing wall 26. Bracket 20 can then be readily placed within the joint 34 as shown in FIG. 5 and the mortar or cement bonding material can then be placed in the joint and the succeeding element 32 can be placed above the joint. A horizontal sectional view of the anchoring construction provided in this embodiment of the invention is shown in FIG. 4 showing the relative disposition of the various parts of the masonry anchor embedded within the inner masonry and the outer facing walls.

FIG. 6 illustrates a second embodiment of a masonry anchor incorporating the principles of the present invention in which bridge sections 12', each of which has a loop 18 at one extremity, are fastened by means such as welding at substantially equally spaced intervals to parallel reinforcing rods 36 of the type generally placed in the joints of a concrete block wall to increase the rigidity of the wall. Reinforcing rods 36, with the anchoring sections 12 fastened thereto, are embedded with in joints 30 and extend continuously along the length of masonry wall 28. It will be appreciated that by placing the reinforcing rods 36, as altered by the present invention, into a concrete block wall in the usual manner, the wall is automatically provided with anchors 18' to which brackets secured in the facing wall may be secured. Thus, by means of the present invention, what are at presenttwo separate operations, i.e. reinforcing a masonry wall and providing the wall with anchors, can be performed simultaneously.

The loop 18 has the same dimensional relationship to the facing units 32 as described above in connection with FIGS. 1-5, and each bracket 20' and its respective loop 18' are interlocked as described above in connection with brackets 20 and loops 18. While the construction shown in FIGS. 8, 9 and 10 shows a bracket such as that illustrated in FIG. 7 embedded within the facing wall, it is to be understood that the embodiment of FIG. 6 can be used to equal advantage with the rectangular bracket shown in FIG. 2. The space between the walls 24 and 26 may be empty, except for the anchors and brackets, as shown in FIGS. 3-5, or it may be filled with mortar or other material, as shown in FIGS. 8-10.

While I have described my invention with reference to several preferred embodiments, it is apparent that modifications may be made to these embodiments without departing from the scope of this invention, which is defined in the appended claims.
