Arrangement applied to modular block with wedge-like couplings

An arrangement applied to a modular block with wedge-like couplings, the arrangement comprising:

• a hollow cobblestone modular block made of polymer, endowed with four walls, a top face and two internal cavities separated by a partition, and, on the top face, two quadratic projections are prominently juxtaposed with a central bore for the passage of tethers used in assembling the masonry, and on the side between the walls there is a vertical extension that prevents the entry of residues from that point inwardly when at least two blocks are joined, wherein the locking and the centralization between the blocks is made by male and female wedge-like couplings;
• on the face of the wall there is a fillet of trapezoidal cross-section, increasing in size from the end to the base of the block, which acts as guide for a compatible recess, having the same cross-section and design, located on the face of the wall;
• in the internal cavities at least eight pairs of wedge-shaped single-wire braids receive the quadratic projections generating a mechanical interference deriving from the male and female wedge-like fitting.
