[0098] A method for constructing a building, subject-matter of the present invention, is described below.

[0099] The method comprises a step of providing a first panel 10 and a second panel 20.

[0100] Each panel 10, 20 comprises a galvanized reinforcement 3 defining a plurality of compartments 4 filled with insulating material, thus obtaining a layer 14 of insulating material. The galvanized reinforcement 3 comprises a first net 3a, a second net 3b parallel to the first net 3a and a third net 3c transverse to the first two nets 3a, 3b to join them.

[0106] The third net 3c is preferably welded to the first two nets 3a, 3b. Preferably, each of the wires that constitute the third net 3c has the ends bent as a reinforcement for the welds. The advantage of such bending is to make the entire cage stronger.

[0107] The reinforcement 3 is to be plastered.

[0108] Preferably, the first net 3a is located on one side of the layer 14 and the second net 3b is located on the opposite side of the layer 14.

[0109] 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.

[0110] Preferably, the internal surface 140 has a pattern defining a plurality of first recesses 142.

[0111] Preferably, the external surface 141 has a pattern defining a plurality of second recesses 143.

[0112] Preferably, the first recesses 142 and the second recesses 143 are offset from each other.

[0113] In the embodiment described and illustrated herein, the first recesses 142 and/or the second recesses 143 have a trapezoidal profile in such a way as to define a corrugated type pattern.

[0114] In an alternative embodiment (not illustrated), the first recesses 142 and/or the second recesses 143 have a rounded profile.

[0115] In an alternative embodiment (not illustrated), the first recesses 142 and/or the second recesses 143 have a square profile.

[0117] The thickness of the insulating material goes from about 10 cm to about 100 cm, as a function of the structural requirements for calculating the reinforcements and the thermal/acoustic insulation required.

[0118] Preferably, both panels 10, 20 are identical modules, the difference lies in the way they are employed, as will be better described below.

[0119] The method comprises a step of arranging the first panel 10 such that it extends predominantly vertically.

[0120] The method comprises a step of arranging the second panel 20 such that it extends predominantly horizontally.

[0121] The method comprises a step of inserting the first bracket 41 inside the second panel 20 such that it is at the first net 3a.

[0122] The method comprises a step of inserting the second bracket 42 inside the second panel 20 such that it is at the second net 3b.

[0123] The method comprises a step of mounting the second panel 20 on the first panel 10. This mounting takes place by positioning through superposition the second panel 20 on the upper end of the first panel 10 and by inserting the first bracket 41 and the second bracket 42 inside the first panel 10 in such a way that they are located respectively at the first net 3a and the second net 3b.

[0124] It can be noted that the step of inserting the first bracket 41, i.e. the internal bracket, inside the second panel 20 takes place before the mounting on the first panel 10.

[0125] The method comprises a step of positioning an angular net 30 and connecting it to the second nets 3b of the first panel 10 and of the second panel 20. 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.

[0126] 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.

[0127] Preferably, the bracket 41, 42 is inserted in such a way as to be located between the layer 14 and the net 3a, 3b.

[0129] 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.

[0130] Preferably, the first bracket 41 is inserted in the first panel 10 at one of the first recesses 142 of the layer 14.

[0131] Preferably, the first bracket 41 is inserted in the second panel 20 at one of the first recesses 143 of the layer 14.

[0132] Preferably, the second bracket 42 is inserted in the first panel 10 at one of the second recesses 143 of the layer 14.

[0133] Preferably, the second bracket 42 is inserted in the second panel 20 at one of the second recesses 143 of the layer 14.

[0134] 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.

[0135] 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 system 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.

[0136] In addition, the proposed solution speeds up and simplifies laying operations compared to the prior art.

[0137] In addition, the proposed solution is modular in that the panels are modules. This allows a unified production standard to be obtained.

[0138] 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.

[0139] In addition, it does not produce pollution for the environment.

[0140] In addition, housing health is high.

[0141] 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.

[0142] In addition, the insertion of the brackets in the recesses increases the structural hold of the proposed system.

[0143] In particular, about improved mechanical strength (anti-seismic, shatter-proof, anti-tornado structure) the results of tests for determination of the compressive strength of the panels 10, 20 of the present invention are reported hereinafter.

[0144] In particular, these tests concern an experimental determination of the compressive strength (according to UNI EN 1052-1 standard) of the panels 10, 20.

[0145] In particular, the tests have been performed on samples of panels 10, 20 having total thickness SF of 20 cm, wherein the layer 14 of insulating material has thickness SS of 15 cm. Moreover, the samples of panels 10, 20 have a square shape with length and width of 100 cm.

[0146] Furthermore, the the layer 14 of insulating material is made of sintered expanded polystyrene (EPS), and the plaster layers 70a, 70b are made of grout.

[0147] The following results concern three of these samples named Samples 1, 2 and 3.

[0148] Following the compression tests, the values of the following parameters have been determined: [0149] The maximum load, Fmax, in kN; [0150] The compressive strength, fmax, in MPa, that is calculated as:

[00001]$f_{\max }=\frac{F_{\max }}{A}$ [0151] where A is the area of the cross-section of the panel subjected to the compressive stress; [0152] The modulus of elasticity, E, in MPa, that is calculated as:

[00002]$E=\frac{F_{\max }}{3.Math.{}_{1/3F\max }.Math.A}$ [0153] where .sub.1/3fmax is the deformation evaluated at a load equal to of the maximum load recorded during the test.

[0154] The results of the compression tests for the three samples are reported in the following Table 1.

TABLE-US-00001 TABLE 1 Fmax A f.sub.max E Sample [kN] [mm.sup.2] [MPa] [MPa] Sample 1 615.5 201267 3.06 813 Sample 2 668.9 200767 3.33 748 Sample 3 679.1 200801 3.38 746 Mean 654.5 / 3.26 769 Standard Deviation 34.2 / 0.17 38

[0155] Thus, as shown by the above results, the panels 10, 20 of the present modular system 1, and thus the modular system 1 itself, have a great compressive strength which make them suitable anti-seismic, shatter-proof, anti-tornado structure.

[0156] About thermal insulation, the results of tests for determination of this feature of the panels 10, 20 of the present invention are reported hereinafter.

[0157] In particular, these tests concern determination of periodic thermal transmittance, attenuation and phase shifting (according to UNI EN ISO 13786 standard) of the panels 10, 20. In particular, the tests have been performed on samples of panels 10, 20 having total thickness SF of 20 cm, wherein the layer 14 of insulating material has thickness SS of 15 cm. Moreover, the samples of panels 10, 20 have a square shape with length and width of 120 cm.

[0158] Furthermore, the layer 14 of insulating material is made of sintered expanded polystyrene (EPS), and the plaster layers 70a, 70b are made of grout.

[0159] The following parameters, which are defined in UNI EN ISO 13786 standard, have been calculated: [0160] periodic thermal transmittance Yie, which is measured in W/m.sup.2K; [0161] attenuation factor fa (i.e., the ratio of the periodic thermal transmittance Yie to the stationary transmittance), that is a dimensionless number; [0162] phase shift f (i.e., time between the maximum temperature recorded outside and inside a building), that is measured in hours.

[0163] The calculation of the above parameters has been made on samples of panels 10, 20 having the features reported in the following Table 2.

TABLE-US-00002 TABLE 2 Thermal Component of the conductivity Density specific heat panel [WmK] [kg/m3] [J/kg K] Plaster layer 0.844 1740 1000 Layer of insulation 0.034 20 1300 material Galvanized 80 7500 1000 reinforcement

[0164] The results of the test are reported in the following Table 3.

TABLE-US-00003 TABLE 3 Dynamic regime (stabilized period T = 24 h) Periodic thermal Attenuation Phase shift transmittance [W/m.sup.2K] factor [hours] 0.273 0.814 3.75

[0165] Thus, as shown by the above results, the panels 10, 20 of the present modular system 1, and thus the modular system 1 itself, have a low periodic transmittance and a great attenuation factor, which make them suitable for a great thermal insulation.

[0166] About noise fractionation and soundproof, the results of tests for determination of the airborne sound insulation of the panels 10, 20 of the present invention are reported hereinafter.

[0167] In particular, these tests concern determination of laboratory measurement of air sound insulation (according to the UNI EN ISO 10140-2:2021 standard) of the panels 10, 20.

[0168] Specifically, the tests have been performed on samples of panels 10, 20 having total thickness SF of 20 cm, wherein the layer 14 of insulating material has thickness SS of 15 cm. Moreover, the samples of panels 10, 20 have length and width of 150 cm and 125 cm, respectively. Furthermore, the layer 14 of insulating material is made of sintered expanded polystyrene (EPS), and the plaster layers 70a, 70b are made of grout.

[0169] The following parameter, according to UNI EN ISO 10140-2:2021 standard and procedures reported in UNI EN ISO 717-1:2021 standard, have been calculated: [0170] sound insulation rating index Rw of the sound insulation power (that is measure in dB), equal to the value of a reference curve at 500 Hz; [0171] corrective term C to be added to Rw; [0172] corrective term Cyr to be added to Rw.

[0173] The following results of sound insulation rating index and corrective terms are obtained:

Rw(C,Ctr)=41(1,3) dB,

wherein the sound insulation power evaluation index Rw processed by proceeding in steps of 0.1 dB and its corrective terms are:

[00003]$\mathrm{Rw}=\left(41.20\text{.4}\right)\mathrm{dB},$$\mathrm{Rw}+C=\left(39.90\text{.5}\right)\mathrm{dB},$$\mathrm{Rw}+C_{tr}=\left(38.20\text{.6}\right)\mathrm{dB}.$

[0174] Thus, as shown by the above results, the panels 10, 20 of the present modular system 1, and thus the modular system 1 itself, have a high sound insulation power which make them suitable for a great sound insulation.
