Abstract

A modular wall block is adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall. The wall block has a front and rear, top and bottom, and opposing sides. The top and bottom define respective substantially planar stacking surfaces. A shear lug projects from one of the planar stacking surfaces of the top and bottom. A block-locating jut is formed with at least one of the opposing sides, and projects from the side at a point intermediate the top and bottom towards one of the planar stacking surfaces. The block-locating jut defines a base surface substantially coplaner with the stacking surface, and a lug-engaging shoulder adapted for engaging a shear lug of a wall block located in an adjacent stacked course.

Claims (26)

1. A modular wall block adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall, said wall block comprising:

a front and rear, top and bottom, and opposing sides, said top and bottom defining respective substantially planar stacking surfaces;

a shear lug projecting from one of said planar stacking surfaces of said top and bottom;

a block-locating jut formed with at least one of said opposing sides, and comprising a plurality of converging planar surfaces projecting from said side beginning at a point intermediate said top and bottom, and extending at an outward angle towards one of said planar stacking surfaces, and said converging planar surfaces intersecting at an apex spaced apart from said side beginning at said point intermediate said top and bottom, and said apex is substantially co-planar to one of said stacking surfaces; and

said block-locating jut further defining a lug-engaging shoulder adapted for engaging a shear lug of a wall block located in an adjacent stacked course.

2. The modular wall block according to claim 1 , wherein said opposing sides angle inwardly from said front to said rear.

3. The modular wall block according to claim 1 , wherein said shear lug is integrally formed with said wall block adjacent said rear.

4. The modular wall block according to claim 1 , wherein said front of said wall block defines a block face comprising spaced-apart vertical breaks defining a center face portion and opposing side face portions.

5. The modular wall block according to claim 4 , wherein said lug-engaging shoulder extends substantially parallel to the center face portion of said front.

6. The modular wall block according to claim 1 , wherein at least one of said opposing sides defines a slot.

7. The modular wall block according to claim 6 , further comprising a mechanical course connector received in the slot formed with said side.

8. A modular wall block adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall, said wall block comprising:

a front and rear, top and bottom, and opposing sides, said top and bottom defining respective substantially planar stacking surfaces;

a shear lug projecting from one of said stacking surfaces of said top and bottom;

a first and second block-locating juts formed with respective opposing sides, and each of said block-locating juts comprising a plurality of converging planar surfaces projecting from said side beginning at a point intermediate said top and bottom and extending at an outward angle towards said planar stacking surface opposite said shear lug, and said converging planar surfaces intersecting at an apex spaced apart from said side beginning at said point intermediate said top and bottom, and said apex is substantially co-planar to said stacking surface opposite said shear lug; and

each of said block-locating juts further defining a lug-engaging shoulder adapted for engaging a shear lug of a wall block located in an adjacent stacked course.

9. A retaining wall constructed of an assembly of modular wall blocks arranged in stacked courses, each of said wall blocks comprising:

a front and rear, top and bottom, and opposing sides, said top and bottom defining respective substantially planar stacking surfaces;

a shear lug projecting from one of said stacking surfaces of said top and bottom;

a block-locating jut formed with at least one of said opposing sides, and comprising a plurality of converging planar surfaces projecting from said side beginning at a point intermediate said top and bottom, and extending at an outward angle towards one of said planar stacking surfaces, and said converging planar surfaces intersecting at an apex spaced apart from said side beginning at said point intermediate said top and bottom, and said apex is substantially co-planar to one of said stacking surfaces; and

said block-locating jut further defining a base surface and a lug-engaging shoulder adapted for engaging a shear lug of a wall block located in an adjacent stacked course.

10. The retaining wall according to claim 9 , wherein said opposing sides of said wall block angle inwardly from said front to said rear.

11. The retaining wall according to claim 9 , wherein said shear lug is integrally formed with said wall block adjacent said rear.

12. The retaining wall according to claim 9 , further comprising at least one course connector for mechanically interconnecting adjacent stacked courses of said wall blocks.

13. The retaining wall according to claim 9 , wherein said front of said wall block defines a block face comprising spaced-apart vertical breaks defining a center face portion and opposing side face portions.

14. The retaining wall according to claim 13 , wherein said lug-engaging shoulder extends substantially parallel to the center face portion of said front of said wall block.
