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 (22)

1. A combination comprising a veneer and a veneer connector, the veneer connector comprising exactly two semi-cylindrical portions adapted to being placed in a connector channel of a veneer or a block, the two semi-cylindrical portions being connected by a flat sheet portion, the flat sheet portion defining a plane, and two or more tab portions, a first tab portion being present on a first side of the plane and a second tab portion being present on a second side of the plane, each tab portion being perpendicular to the flat sheet portion, and wherein the veneer connector is formed from a single sheet of material.

2. The combination of claim 1 , wherein one of the two semi-cylindrical portions of the veneer connector is disposed within a connector channel of the veneer.

3. The combination of claim 1 , wherein the veneer connector comprises exactly two tab portions and each tab portion is equidistant from the two semi-cylindrical portions.

4. The combination of claim 1 , wherein the veneer connector is made of metal.

5. The combination of claim 1 , wherein the veneer connector is made of steel.

6. The combination of claim 1 , wherein the veneer is a real stone veneer.

7. The combination of claim 1 , wherein the veneer is a concrete veneer.

8. The combination of claim 7 , wherein the concrete veneer has metal mesh reinforcement.

9. 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 a rear face, the 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 rear face; 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;

the veneer connector comprising exactly two semi-cylindrical portions adapted to being placed in a connector channel of a veneer or a block, the two semi-cylindrical portions being connected by a flat sheet portion, the flat sheet portion defining a plane, and two or more tab portions, a first tab portion being present on a first side of the plane and a second tab portion being present on a second side of the plane, each tab portion being perpendicular to the flat sheet portion, and wherein the veneer connector is formed from a single sheet of material; and

a portion of the veneer connector being disposed within the wall block connector channel.

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

11. The combination of claim 9 , wherein the veneer connector comprises exactly two tab portions and each tab portion is equidistant from the two semi-cylindrical portions.

12. The combination of claim 9 , wherein the veneer connector is made of metal.

13. The combination of claim 12 , wherein the veneer connector is made of steel.

14. The combination of claim 9 , wherein the wall block is a concrete wall block.

15. The combination of claim 14 , wherein the veneer is a real stone veneer.

16. The combination of claim 14 , wherein the veneer is a concrete veneer.

17. The combination of claim 16 , wherein the concrete veneer has metal mesh reinforcement.

18. A wall comprising a first course and a second course of wall blocks, a plurality of wall blocks comprising parallel top and bottom faces, a front face and a rear face, the 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 rear face; 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; a plurality of veneer connectors comprising exactly two semi-cylindrical portions adapted to being placed in a connector channel of a veneer or a block, the two semi-cylindrical portions being connected by a flat sheet portion, the flat sheet portion defining a plane, and two or more tab portions, a first tab portion being present on a first side of the plane and a second tab portion being present on a second side of the plane, each tab portion being perpendicular to the flat sheet portion, and wherein the veneer connector is formed from a single sheet of material; and a portion of the veneer connectors being disposed within the wall block connector channels.

19. The wall of claim 18 , wherein the wall is a retaining wall.

20. The wall of claim 18 , wherein veneers are attached to a plurality of the veneer connectors.
