Prefabricated modular system for constructing a sustainable dwelling

A prefabricated modular system for sustainable dwelling construction comprising:

• a foundation slab 100;
• walls built from pieces or blocks of the tongue-and-groove type 200;
• a slab for a mezzanine roof and/or roof 300, 400, 500;
• wherein said slab 500 is made up of two main components defined by a precast base 510 that in its internal part houses a portion of a support structure 520;
• wherein the precast base 510 is made of concrete and has a rectangular cross section that in two of its ends have an L-shaped support flange 511 configured so that the ends of tablets 502 rest on it;
• the support structure 520 is partially inside the precast base 510, and is composed of a plurality of bars of preferably circular cross-section where in an upper part a main bar 521 is located in a horizontal arrangement, in a lower part of said main bar 521 there is a plurality of pyramidal arrangements 522 integrated each of these arrangements by at least four bars in a triangular arrangement that at each of their lower ends are joined by electro welding with a longitudinal tension arrangement 523 that are at least three bars parallel to each other and which are interconnected by a connecting bar 524 and which is coupled in a perpendicular arrangement with respect to the axial axes of the bars that make up the longitudinal tension arrangement where the support structure 520 is located inside the precast base from an area proximal to the lower part of pyramid arrangements 5 22 to the bottom of the longitudinal tension arrangement 523;
• wherein the tablets 502 are made up of two main components, a main base 530 and an insulating cover 540;
• wherein the main base 530, has a globally rectangular cross-section and that at each of its ends locates an inverted L-shaped flange 531, which during the assembly of the modular system for construction 500 is interconnected with the support groove 511 of the precast base 510, on the upper face of the main base and perpendicular to the groove 511, the main base 530 has at least one pair of reinforcing projections 532 that are arranged in a truncated pyramidal shape in where the lower base of this interconnects with the upper face of the main base 530, while the insulating cover 540 preferably made of polystyrene, has a generally prismatic rectangular shape that in its lower part has at least one pair of grooves 541 of truncated pyramidal cross section, which interconnects with the reinforcing projections 532 of the main base 530;
• wherein the slab 500 is made up of a precast base 510 that in its internal part houses a portion of a support structure 520, where the precast base 510 is made of concrete, it has a rectangular cross section that in two of its ends has an L-shaped support flange 511 configured so that the ends of tablets 502 rest on it;
• the support structure 520 is partially inside the precast base 510, and is composed of a plurality of bars of preferably circular cross-section where in the upper part a main bar 521 is located in a horizontal arrangement, in the lower part of said main bar 521 there is a plurality of pyramidal arrangements 522 integrated each of these arrangements by at least four bars in a triangular arrangement that at each of their lower ends are joined by electro welding with a longitudinal tension arrangement 523 that are It consists of at least three bars parallel to each other and which are interconnected by means of a connecting bar 524 of preferably cylindrical shape and which is coupled in a perpendicular arrangement with respect to the axial axes of the bars that make up the longitudinal tension arrangement where the support structure 520 is located inside the precast base from an area proximal to the bottom of the pyramidal arrays 522 to the bottom of the longitudinal tension array 523 and where the tablets 502 are made up of two main components, a main base 530 and an insulating cover 540;
