Abstract

A retaining wall block having a false joint and a system of retaining wall blocks. The retaining wall block includes a body having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can have a depth divided by the width greater than two inches. The false joint can have an interior angle of less than ten degrees. The system includes a plurality of retaining wall blocks and a first course of retaining wall blocks engaged with a second course of retaining wall blocks below. Each block in the system comprising a front face having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can extend a predetermined depth of a third surface.

Claims (31)

1. A masonry block comprising:

a body having a front structure with a top surface, two side surfaces and a bottom surface; and

two middle structural members extending a predetermined distance between the front structure and a rear structural member, wherein the middle structural members are insert laterally from one of the side surfaces and each include an engagement cavity having a first angle, an engagement protrusion opposed to the engagement cavity having a second angle and a transition region between engagement cavity and the engagement protrusion wherein a distance between the engagement cavity and the engagement protrusion reduces from a first value to a second value;

wherein the first angle extends for a predetermined distance within the engagement cavity.

2. The masonry block of claim 1 wherein a depth of the engagement cavity of at least one of the middle structural members is equal to or less than a depth of the engagement protrusion of the at least one of the middle structural members.

3. The masonry block of claim 1 wherein a depth of the engagement cavity of at least one of the middle structural members is equal to or less than a height of a protrusion of the engagement protrusion of the at least one of the middle structural members.

4. The masonry block of claim 1 wherein the engagement cavity further comprises a third angle.

5. The masonry block of claim 1 wherein the engagement protrusion further comprises a fourth angle.

6. The masonry block of claim 1 wherein the engagement protrusion is contiguous with a cavity.

7. The masonry block of claim 1 wherein the engagement protrusion further comprises a fourth angle that is contiguous with a cavity.

8. The masonry block of claim 7 wherein the body defines an H-shaped structure.

9. A retaining wall comprising:

a first course of a plurality of retaining wall blocks, each block comprising:

a body having a front structure with a top surface and a bottom surface; and

two middle structural members inset laterally from one of two side surfaces of the front structure and extending between the front structure and a rear structural member, wherein the middle structural members each include an engagement cavity having a first angle, a lower portion an engagement protrusion having a second angle and a transition region disposed between a top surface and a bottom of the block, wherein a distance between the engagement cavity and the engagement protrusion reduces from a first value to a second value; and

a second course of retaining wall blocks above the first course;

wherein the first angle extends for a predetermined distance over the engagement cavity.

10. The retaining wall of claim 9 wherein a depth of the engagement cavity of at least one of the middle structural members is equal to or less than a depth of the engagement protrusion of the at least one of the middle structural members.

11. The retaining wall of claim 9 wherein a depth of the engagement cavity of at least one of the middle structural members is equal to or less than a height of a protrusion of the engagement protrusion of the at least one of the middle structural members.

12. The retaining wall of claim 9 wherein the engagement cavity further comprises a third angle.

13. The retaining wall of claim 9 wherein the engagement protrusion further comprises a fourth angle.

14. The retaining wall of claim 9 wherein the engagement protrusion is contiguous with a protrusion.

15. The retaining wall of claim 9 wherein the engagement protrusion further comprises a fourth angle that is contiguous with a protrusion.

16. The retaining wall of claim 9 wherein the first surface is opposite the second surface.

17. A masonry block comprising:

a body having a front structure with a top surface and a bottom surface; and

two middle structural members, each inset laterally from a side surface and extending between the front structure and a rear structural member, wherein the middle structural members each include an engagement cavity having a first angle, a an engagement protrusion having a second angle and a transition region below the top surface and configured to interlock with the engagement cavity of a second block, wherein a distance between the engagement cavity and the engagement protrusion reduces from a first value to a second value;

wherein the first angle extends for a predetermined distance over the engagement cavity.

18. The masonry block of claim 17 wherein a depth of the engagement cavity of at least one of the middle structural members is equal to or less than a depth of the engagement protrusion of the at least one of the middle structural members to provide room for movement between the engagement cavity of a first block and the engagement protrusion of a second block.

19. The masonry block of claim 18 wherein a depth of the engagement cavity of at least one of the middle structural members is equal to or less than a height of a protrusion of the engagement protrusion of the at least one of the middle structural members to provide room for movement between the engagement cavity of a first block and the engagement protrusion of a second block.

20. The masonry block of claim 1 wherein the engagement cavity further comprises a third angle configured to provide room for movement between the engagement cavity of a first block and the engagement protrusion of a second block.
