Interlocking construction block

1. A construction block comprising:

two side panels of rectangular shape and of equal dimensions, facing each other and parallel to each other;

an outer partition located at 90° of said two side panels, said outer partition having a length equal to the height of the side panels, said outer partition having a width smaller than the distance between the side panels, ends each of the longitudinal ends of said outer partition being attached to each of the longitudinal ends of said side panels by means of a first tab and a second tab, each of said first and second tabs being perpendicular to the outer partition, each of said first and second tabs attached to an inside surface of the edge that constitutes the height of the outer partition, said outer partition being attached to the side panels so that one of the edges of said outer partition extends beyond one of the edges of the side panel, said outer partition having at least one through hole;

a third tab and a fourth tab projecting from the edge of the outer partition and beyond the edge of the side panels, perpendicular to said outer partition and without reaching the edge of each side panel that is farther from the outer partition, each of said third and fourth tabs respectively attached to an inner edge of one of the side panels;

one or more inner partitions attached to the inside surfaces of the two side panels and of the third and fourth tabs, each of said inner partitions extending parallel to the outer partition, from the same end as the outer partition and having the same length as said outer partition, each of the inner partitions having at least one through hole, the inner partition that is farthest from the outer partition being attached to the end of the second and third tabs that is farther from the outer partition.

2. The construction block of claim 1 , wherein:

the first and second tabs are folded so as to form a first and a second groove extending over all or part of the length of said tabs, while the third and fourth tabs are folded so as to form a third and fourth groove extending over the length of said tabs; and

each side panel having two pairs of tabs extending perpendicular to the panels, a pair made up of a fifth and a sixth tab located at the opposite end respect of the first and second grooves, respectively, and a pair made up of a seventh and an eighth tab located at the opposite end respect of the third and fourth grooves, respectively, each tab of said two pairs of tabs having a width smaller than or equal to the depth of the grooves, the fifth and sixth tabs extending vertically over the height of the side panel, from the upper edge of the side panel over a length equal to or smaller than that of the first and second grooves, respectively, the seventh and eighth tabs extending horizontally over the length of the side panel, from the front edge of the side panel over a length equal to or smaller than that of the third and fourth grooves, respectively.

3. The construction block according to claim 2 , wherein the fifth, sixth, seventh and eighth tabs have a width equal to the depth of the grooves.

4. The construction block according to claim 3 , wherein the fifth, sixth, seventh and eighth tabs extend over a length equal to that of the first, second, third and fourth grooves, respectively.

5. The construction block according to claim 4 , wherein the holes in the different partitions are circular in section and are aligned horizontally.

6. The construction block according to claim 5 , further comprising one or more pairs of inner tabs attached to the inside surface of the side panel, each tab of a pair of tabs facing the other tab of the same pair.

7. The construction block according to claim 6 , further comprising thermal and/or acoustic insulation attached to at least one of the inside surfaces of the side panels.

8. The construction block according to claim 7 , wherein the thermal insulation is neoprene.

9. The construction block according to claim 6 , wherein the side panels have relief texture.

10. The construction block according to claim 5 , wherein the side panels have relief texture.

11. The construction block according to claim 1 , wherein the holes in the different partitions are circular in section and are aligned horizontally.

12. The construction block according to claim 11 , further comprising thermal and/or acoustic insulation attached to at least one of the inside surfaces of the side panels.

13. The construction block according to claim 12 , wherein the thermal insulation is neoprene.

14. The construction block according to claim 1 , further comprising blind covers at said longitudinal ends.
