Abstract

Wall blocks, veneers, veneer connectors, walls, and methods of constructing walls are provided. More particularly, the invention relates to constructing walls in which a veneer panel is attached to a wall block with a connector and in which the front faces of the veneers have a desirable texture.

Claims (40)

1. A veneer connector comprising a support, bifurcated horizontal prongs that extend from the support and a stop that extends from the support and is located below the bifurcated horizontal prongs, wherein the support comprises a flat surface from which the bifurcated horizontal prongs and the stop extend, and wherein the stop comprises a first planar surface that extends from the flat surface of the support and is perpendicular to the flat surface, a second planar surface that extends from the flat surface of the support and forms an acute angle with the flat surface, and a third planar surface that connects between the first and second surfaces and forms an obtuse angle with the first planar surface.

2. The veneer connector of claim 1 , wherein the veneer connector further comprises a stop located above the bifurcated horizontal prongs.

3. The veneer connector of claim 1 , wherein the bifurcated horizontal prongs have a horizontal length and the stop has a horizontal length, the horizontal length of the stop being less than the horizontal length of the prongs.

4. The veneer connector of claim 1 , wherein the bifurcated horizontal prongs comprise tabs at the ends of the prongs.

5. The veneer connector of claim 1 , wherein the third planar surface is oriented at a 45 degree angle with respect to the flat surface of the support.

6. The veneer connector of claim 1 , wherein the support is in the form of a plate.

7. The veneer connector of claim 1 , wherein the support comprises a shaft having a length longer than the maximum length of the flat surface from which the bifurcated horizontal prongs and the stop extend.

8. The veneer connector of claim 7 , wherein the shaft is adapted to being placed securely in a connector channel of a veneer.

9. A combination comprising a veneer and a veneer connector, the veneer connector comprising a support, bifurcated horizontal prongs that extend from the support and a stop that extends from the support and is located below the bifurcated horizontal prongs, wherein the support comprises a flat surface from which the bifurcated horizontal prongs and the stop extend, and wherein the stop comprises a first planar surface that extends from the flat surface of the support and is perpendicular to the flat surface, a second planar surface that extends from the flat surface of the support and forms an acute angle with the flat surface, and a third planar surface that connects between the first and second surfaces and forms an obtuse angle with the first planar surface.

10. The combination of claim 9 , wherein the veneer connector is fixedly attached to the veneer.

11. The combination of claim 10 , wherein the veneer connector is fixedly attached with an adhesive.

12. The combination of claim 9 , wherein a portion of the veneer connector is disposed within a connector channel of the veneer.

13. The combination of claim 9 , wherein the veneer connector further comprises a stop located above the bifurcated horizontal prongs.

14. The combination of claim 9 , wherein the bifurcated horizontal prongs have a horizontal length and the stop has a horizontal length, the horizontal length of the stop being less than the horizontal length of the prongs.

15. The combination of claim 9 , wherein the bifurcated horizontal prongs comprise tabs at the ends of the prongs.

16. The combination of claim 9 , wherein the third planar surface is oriented at a 45 degree angle with respect to the flat surface of the support.

17. The combination of claim 9 , wherein the support is in the form of a plate.

18. The combination of claim 9 , wherein the support comprises a shaft having a length longer than the maximum length of the flat surface from which the bifurcated horizontal prongs and the stop extend.

19. The combination of claim 18 , wherein the shaft is adapted to being placed securely in a connector channel of a veneer.

20. The combination of claim 9 , wherein the veneer is a real stone veneer.

21. The combination of claim 9 , wherein the veneer is a concrete veneer.

22. A combination comprising a wall block, a veneer, and a veneer connector, the wall block comprising parallel top and bottom faces, a front face and one or more rear faces, each rear face being parallel to the front face, and first and second side walls, the first and second side walls extending from the top face to the bottom face and from the front face to the one or more rear faces; and a connector channel for receiving a veneer connector that is oriented in the direction from the top face to the bottom face of the block, the connector channel opening into the top face of the block and one of the front or rear faces of the block and not opening into the one of the front or rear faces of the block for the entire distance from the top face to the bottom face of the block; and

the veneer connector comprising a support, bifurcated horizontal prongs that extend from the support and a stop that extends from the support and is located below the bifurcated horizontal prongs; and

a portion of the veneer connector being disposed with the wall block connector channel, and

wherein the wall block connector channel comprises a lower surface in the form of a ramp that extends from one of the front or rear faces of the block to a back surface of the connector channel, the ramp rising from the one of the front or rear faces of the block to the back surface of the connector channel; the bifurcated horizontal prongs are disposed in the wall block connector channel; and the stop is disposed in the wall block connector channel and contacts the ramp.

23. The combination of claim 22 , wherein the veneer connector is fixedly attached to the veneer.

24. The combination of claim 23 , wherein the veneer connector is fixedly attached with an adhesive.

25. The combination of claim 22 , wherein a portion of the veneer connector is disposed within a connector channel of the veneer.

26. The combination of claim 22 , wherein the veneer connector further comprises a stop located above the bifurcated horizontal prongs.

27. The combination of claim 22 , wherein the bifurcated horizontal prongs have a horizontal length and the stop has a horizontal length, the horizontal length of the stop being less than the horizontal length of the prongs.

28. The combination of claim 22 , wherein the bifurcated horizontal prongs comprise tabs at the ends of the prongs.

29. The combination of claim 22 , wherein the support comprises a flat surface from which the bifurcated horizontal prongs and the stop extend.

30. The combination of claim 29 , wherein the stop comprises a first planar surface that extends from the flat surface of the support and is perpendicular to the flat surface, a second planar surface that extends from the flat surface of the support and forms an acute angle with the flat surface, and a third planar surface that connects between the first and second surfaces and forms an obtuse angle with the first planar surface.

31. The combination of claim 30 , wherein the third planar surface is oriented at a 45 degree angle with respect to the flat surface of the support.

32. The combination of claim 22 , wherein the support is in the form of a plate.

33. The combination of claim 30 , wherein the support comprises a shaft having a length longer than the maximum length of the flat surface from which the bifurcated horizontal prongs and the stop extend.

34. The combination of claim 33 , wherein the shaft is adapted to being placed securely in a connector channel of a veneer.

35. The combination of claim 22 , wherein the wall block is a concrete wall block.

36. The combination of claim 35 , wherein the veneer is a real stone veneer.

37. The combination of claim 35 , wherein the veneer is a concrete veneer.
