Abstract

A system of retaining wall blocks, a method of assembling a retaining wall block assembly, and a mold for manufacturing retaining wall blocks having adjustable engagement configurations.

Claims (34)

1. A concrete block comprising:

a front member having a bottom surface;

a rear member oriented parallel to the front member;

two transverse members connecting the front member to the rear member and forming a core therebetween; and

wherein at least one transverse member comprises an integrally-formed engagement protrusion located on a bottom surface of the transverse member and extending below the bottom surface of the front member, the engagement protrusion opposite from an integrally formed cavity of the transverse member, wherein the transverse members are spaced apart from each other and the rear member has a width between sides of the concrete block that is less than a width between sides of the concrete block of the front member.

2. The concrete block of claim 1 , wherein the sides of the integrally-formed engagement protrusion are coplanar with the sides of the transverse member.

3. The concrete block of claim 1 , wherein at least one side of the integrally-formed engagement protrusion are coplanar with at least one side of the transverse member.

4. The concrete block of claim 1 wherein the transverse members are spaced such that stacking multiple courses of the concrete blocks causes the transverse members to superpose each other.

5. The concrete block of claim 1 wherein the transverse members are spaced such that stacking two or more courses of the concrete blocks in an overlap running bond causes the transverse members of at least one block in each course to superpose each other.

6. The concrete block of claim 1 , further comprising a plurality of integrally-formed engagement protrusions.

7. The concrete block of claim 1 further comprising a plurality of integrally-formed engagement protrusions, wherein the sides of the integrally-formed engagement protrusion are coplanar with at least one side of the transverse members.

8. The concrete block of claim 1 further comprising a plurality of integrally-formed engagement protrusions, wherein the sides of the integrally-formed engagement protrusions are parallel with each other.

9. The concrete block of claim 1 further comprising a plurality of integrally-formed engagement protrusions, wherein the sides of the integrally-formed engagement protrusion are at least partially parallel with each other.

10. A wall comprising:

a plurality of concrete blocks, each concrete block including:

a front member having a bottom surface;

a rear member oriented parallel to the front member;

two transverse members connecting the front member to the rear member and forming a core therebetween; and

wherein at least one transverse member comprises an integrally-formed engagement protrusion located on a bottom surface of the transverse member and extending below the bottom surface of the front member, the engagement protrusion opposite from an integrally formed cavity of the transverse member, wherein the sides of the engagement protrusion are coplanar with at least one side of the transverse member and a width between parallel sides of the rear member is narrower than a width between parallel sides of the front member of each concrete block.

11. The wall of claim 10 , wherein the sides of the engagement protrusion are coplanar with the sides of the transverse member.

12. The wall of claim 10 wherein the transverse members are spaced apart from each other.

13. The wall of claim 10 wherein the transverse members are spaced such that stacking multiple courses of the concrete blocks causes the transverse members to superpose each other.

14. The wall of claim 10 wherein two or more of the transverse members are spaced such that stacking two or more courses of the concrete blocks in an overlap running bond causes the transverse members to superpose each other.

15. The wall of claim 10 , wherein the sides of the engagement protrusion are coplanar with the sides of the corresponding transverse members.

16. The wall of claim 10 , wherein at least one side of the engagement protrusion is coplanar with at least one side of the corresponding transverse members.

17. The wall of claim 10 , wherein the sides of the engagement protrusion are parallel with each other.

18. The wall of claim 10 wherein the sides of the engagement protrusion are at least partially parallel with each other.

19. The wall of claim 10 , wherein at least one side of the engagement protrusion is coplanar with at least one side of the corresponding transverse members and the sides of the engagement protrusion are parallel with each other.

20. A wall comprising:

a plurality of concrete blocks, each concrete block including:

a front member having a bottom surface;

a rear member oriented parallel to the front member;

two transverse members connecting the front member to the rear member and forming a core therebetween; and

wherein at least one transverse member comprises an integrally-formed engagement protrusion located on a bottom surface of the transverse member and extending below the bottom surface of the front member, the engagement protrusion opposite from an integrally formed cavity of the transverse member, wherein the sides of the engagement protrusion are coplanar with at least one side of the transverse member and a width between parallel sides of the rear member is narrower than a width between parallel sides of the front member of each concrete block, wherein at least one side of the engagement protrusion is coplanar with at least one side of the corresponding transverse members and the sides of the engagement protrusion are at least partially parallel with each other.
