초록 ▼

A double-wall structure, such as a fence wall or a parapet wall, has two back-to-back walls each constructed of successive courses of concrete wall blocks dry-stacked one atop another with each succeeding course set back relative to the immediately preceding course so that the two walls converge upwardly towards one another and are capped at the top by cap blocks. Each wall block has protuberances that protrude upwardly from the top face of the block and a groove provided in the bottom face thereof. The groove is located and dimensioned relative to the protuberances so that the grooves of wall blocks in each succeeding course engage with the protuberances of wall blocks in the immediately preceding course to establish the setback distance between abutting courses of wall blocks.

1. A double-wall structure comprising: two back-to-back wall sections each comprising successive courses of wall blocks dry-stacked one atop another with each succeeding course set back relative to the immediately preceding course so that the two back-to-back wall sections converge upwardly towards one another; and a foundation comprising one or more courses of base blocks beneath each wall section of wall blocks and on which the wall sections of wall blocks are erected, the base blocks having a greater front-to-rear depth than that of the wall blocks; wherein the lowermost course of wall blocks in each wall section is set back relative to the uppermost course of base blocks on which the lowermost course of wall blocks is erected, and wherein the setback distance between successive courses of wall blocks is the same, and the setback distance between the lowermost course of wall blocks and the uppermost course of base blocks is the same as that between successive courses of wall blocks. 2. A double-wall structure according to claim 1; wherein the foundation beneath at least one of the wall sections of wall blocks comprises successive courses of base blocks stacked one atop another with each succeeding course set back relative to the immediately preceding course. 3. A double-wall structure according to claim 2; wherein the foundation constitutes a retaining wall and the double-wall structure erected on the foundation constitutes a parapet wall. 4. A double-wall structure according to claim 3; further including cap blocks that cap the top of the parapet wall. 5. A double-wall structure according to claim 2; wherein the setback distance between successive courses of base blocks is the same. 6. A double-wall structure according to claim 2; wherein the setback distance between successive courses of base blocks is the same as that between successive courses of wall blocks. 7. A double-wall structure according to claim 1; wherein the uppermost courses of base blocks, on which the lowermost courses of wall blocks are erected, are situated at or below ground level, and the double-wall structure erected on the uppermost courses of base blocks constitutes a fence wall. 8. A double-wall structure according to claim 7; further including cap blocks that cap the top of the fence wall. 9. A double-wall structure according to claim 1; wherein the space between the back-to-back wall sections is substantially or completely filled with loose stone. 10. A double-wall structure according to claim 1; wherein the base blocks in each course of base blocks all have the same size. 11. A double-wall structure according to claim 1; wherein the top-to-bottom height of the wall blocks is the same as that of the base blocks. 12. A double-wall structure according to claim 11; wherein the maximum side-to-side width of the wall blocks is the same as that of the base blocks. 13. A double-wall structure according to claim 1; wherein the maximum side-to-side width of the wall blocks is the same as that of the base blocks. 14. A double-wall structure according to claim 1; wherein the wall blocks and the base blocks are molded concrete blocks. 15. A double-wall structure according to claim 1; wherein each of the wall blocks and base blocks has spaced-apart front and rear sections interconnected by two laterally spaced-apart side sections that jointly define a through-cavity that extends through the block from a top face thereof to a bottom face thereof, and wherein each of the wall blocks and base blocks has protuberances protruding upwardly from the top face of the front section frontward of the through-cavity and a groove provided in the bottom face of the front section frontward of the through-cavity, the groove being located and dimensioned relative to the protuberances so that the grooves in the blocks in each succeeding course engage with the protuberances of the blocks in the immediately preceding course with each succeeding course set back relative to the immediately preceding course. 16. A double-wall structure according to claim 15; wherein the groove in each block has spaced-apart front and rear walls and is located and dimensioned relative to the protuberances so that one but not both of the front and rear walls of the grooves in the blocks in each succeeding course engages with the protuberances of the blocks in the immediately preceding course. 17. A double-wall structure according to claim 15; wherein the protuberances of each wall block and base block have straight rear sides all lying along a common straight line. 18. A double-wall structure according to claim 15; wherein through-cavities of wall blocks in each succeeding course partly overlap through-cavities of wall blocks in the immediately preceding course; and further comprising a filler substantially or completely filling the overlapping through-cavities. 19. A double-wall structure according to claim 18; wherein the filler comprises loose stone. 20. A double-wall structure according to claim 18; wherein the wall blocks in each succeeding course are staggered relative to the wall blocks in the immediately preceding course. 21. A double-wall structure according to claim 15; further including cap blocks that cap the tops of wall blocks in the uppermost courses of the two back-to-back wall sections. 22. A double-wall structure according to claim 21; wherein each cap block caps at least part of the tops of wall blocks of both wall sections. 23. A double-wall structure according to claim 22; wherein the cap blocks have grooves that engage with the protuberances protruding upwardly from the top faces of the uppermost courses of wall blocks. 24. A double-wall structure according to claim 1; wherein the wall blocks of each wall section have a textured front surface that faces outwardly of the double-wall structure. 25. A double-wall structure according to claim 1; wherein the wall blocks have textured front surfaces that are divided into panels of different sizes.
