[0006] Prefabricated systems of the beam-pillar type are known. A system of this type is described in document EP3884122 A1. The latter shows a vertical panel made of a layer of insulating material surrounded by a galvanized reinforcement. These components are flanked by a vertical reinforcement that is filled with hardening material to obtain a pillar and a horizontal reinforcement that is filled with hardening material to obtain a beam. The beam and the pillar perform the function of structural support and are essential in case a building is redeveloped with a large number of floors.

[0007] However, this solution proves to be complex for buildings with a small number of floors, where the total load borne by the system is contained in the extent. The need is therefore felt for a new modular system designed specifically for buildings with a reduced number of floors.

[0012] - at least one second bracket inserted in the first panel and in the second panel at the respective second nets.

[0013] In accordance with one embodiment, each bracket is fixed to the respective nets.

[0014] In accordance with one embodiment, the bracket in the panel is interposed between the layer and the net.

[0015] Preferably, for each panel the layer of insulating material has a first surface at the first net and a second surface at the second net. The first surface has a pattern defining a plurality of first recesses. The second surface has a pattern defining a plurality of second recesses.

[0016] In accordance with one embodiment, the first bracket is inserted in the first panel and in the second panel at one of the respective first recesses and the second bracket is inserted in the first panel and in the second panel at one of the respective second recesses.

[0017] Preferably, the bracket is substantially L-shaped.

[0018] In accordance with one embodiment, the modular system comprises a substantially horizontal beam arranged curbwise between the first panel and the second panel. The beam comprises an iron reinforcement defining a second substantially horizontal niche filled with hardening material.

[0083] The layer 14 of insulating material has a first surface 140 at the first net 3a and a second surface 141 at the second net 3b. For the same reasons, the first surface 140 can be identified as internal and the second surface 141 as external.

[0084] Preferably, the internal surface 140 has a pattern defining a plurality of first recesses 142.

[0085] Preferably, the external surface 141 has a pattern defining a plurality of second recesses 143.

In particular, the angular net 30 is connected, i.e. tied, to two opposite ends respectively to the second net 3b of the first panel 10 and to the second net 3b of the second panel 20.

[0100] Once the angular net 30 is positioned, the structure is ready to receive hardening material (e.g., spray structural grout) in the vertical external zone (from the side of the second net 3b) and subsequently in the horizontal external zone (from the side of the second net 3b). The area inside the panels 10, 20 (therefore from the side of the first net 3a) is ready for the electrical and hydraulic system, after which it will be possible to spray grout internally. Finishes, tiles, windows, etc. will be laid in the last step.

[0103] In particular, in the first panel 10 the second bracket 42 is located interposed between the layer 14 and the second net 3b. In the second panel 20 the second bracket 42 is located interposed between the layer 14 and the second net 3b.

[0104] Preferably, the first bracket 41 is inserted in the first panel 10 at one of the first recesses 142 of the layer 14.

[0105] Preferably, the first bracket 41 is inserted in the second panel 20 at one of the first recesses 143 of the layer 14.

[0106] Preferably, the second bracket 42 is inserted in the first panel 10 at one of the second recesses 143 of the layer 14.

[0107] Preferably, the second bracket 42 is inserted in the second panel 20 at one of the second recesses 143 of the layer 14.

[0108] From the description provided, the features of the modular system for use in construction and the method for constructing a building, according to the present invention, are clear, as are the advantages.

[0109] In particular, the combination of panels made like a cage, with two nets joined transversely by a third one passing through a layer of insulating material, and of the proposed anchoring means allows to create a modular system that is able to support buildings with a maximum number of floors equal to three. This solution is constructively simpler than the described prior art.

[0110] In addition, the proposed solution speeds up and simplifies laying operations compared to the prior art.

[0111] In addition, the proposed solution is modular in that the panels are modules. This allows a unified production standard to be obtained.

[0112] The proposed solution allows to obtain an anti-humidity, anticondensation, anti-mold, anti-seismic, shatter-proof, anti-tornado structure, with high thermal and acoustic insulation.

[0113] In addition, it does not produce pollution for the environment.

[0114] In addition, housing health is high.

[0115] Furthermore, the layer recesses of insulating material allow the generation of micro-columns, for example in grout. The offset construction of the recesses on the two sides results in greater resistance to compression and shatter, as well as better noise fractionation, making the wall more soundproof.

[0116] In addition, the insertion of the brackets in the recesses increases the structural hold of the proposed system.
