  • figure 4 shows a side view of the soundproofing block of figure 1 from the side of arrow IV of figure 1;
  • figure 5 shows a plan view of the soundproofing block of figure 1.
  • reference numeral 4 globally denotes a soundproofing block, suitable for building applications and the like.
  • block 4 comprises three units properly shaped and said connected to one another, and extends along a prevailing direction X.
  • block 4 comprises two side units 8 and one central unit 12, interposed between said side units 8, relative to a cross direction Y perpendicular to said prevailing direction X.
  • the side units 8 are equal to one another in their dimensions and shape and are parallel to one another and to said prevailing direction X.
  • the prevailing X and cross Y directions define a support plane S for said block 4, that is, a plane parallel to a laying surface of the block itself.
  • the two side units 8 are equal to one another in their dimensions and shape, both being shaped as a parallelepiped, with a base parallel to said support plane S and a height parallel to a longitudinal direction Z, perpendicular to said support plane S and to the prevailing and cross directions X and Y.
  • said side units 8 are aligned to one another relative to the prevailing and longitudinal directions X and Z, so as to be superimposable along the cross direction Y.
  • the cross direction Y defines a thickness of the block units.
  • the side units 8 extend from an upper end 13 to a lower end 14, along the longitudinal direction Z, as well as from a front end 15 to a rear end 16, along the prevailing direction X.
  • the central unit 12w exhibits the same dimensions as the side units 8 relative to the prevailing and longitudinal directions X and Z.
  • the block exhibits a centre line plane W perpendicular to the support plane S; preferably, the centre line plane W is also the symmetry plane for the block.
  • the central unit 12 is advantageously arranged staggered relative to the side units 8, along the prevailing and longitudinal directions X and Z, so as to exhibit projecting portions relative to the side units 8.
  • the projecting portions comprise a first projecting portion 18 and a second projecting portion 20.
  • the first projecting portion 18 protrudes relative to the side units 8 along the longitudinal direction Z, for example on the side of the upper end 13 of the side units 8, by a length M.
  • the central unit 12 along the longitudinal direction Z determines with the side units 8 a first recess 24, having a length M' preferably equal to said length M.
  • the first recess 24 is counter-shaped relative to the first projecting portion 18 so as to allow a shape coupling between the first projecting portion 18 and the first recess 24.
  • the second projecting portion 20 protrudes relative to the side units 8 along direction X, for example on the side of the front ends 15 of the side units 8, by a length P.
  • the central unit 12, along direction X determines with the side units 8 a second recess 26, having a length P' preferably equal to said length P.
  • the second recess 26 is counter-shaped relative to the second projecting portion 20 so as to allow a shape coupling between the second projecting portion 20 and the second recess 26.
  • said first projecting portion 18 comprises a pair of upper longitudinal chamfers 28, inclined by an angle a relative to a plane parallel to the centre line plane W, that is, passing by the prevailing and longitudinal directions X, Z, and symmetrically arranged relative to said plane W so that, relative to a section plane perpendicular to said centre line plane W, that is, passing by the longitudinal and cross directions Z and Y, the first projecting portion 18 exhibits a trapezoidal section, in particular an isosceles trapezium section.
  • said angle a is equal to 45 degrees.
  • said first recess 24 comprises a pair of lower longitudinal chamfers 30, inclined by an angle a' relative to a plane parallel to the centre line plane W and symmetrically arranged relative to said plane.
  • said lower longitudinal chamfers 30 are parallel to the upper longitudinal chamfers 28, that is, angle a is equal to angle a', so that on the whole, the first recess 24 is counter-shaped relative to the first projecting portion 18.
  • said second projecting portion 20 comprises a pair of front side chamfers 32, inclined by an angle b relative to a plane parallel to the centre line plane W, that is, passing by the cross and longitudinal directions Y and Z, and symmetrically arranged relative to said centre line plane W so that, relative to a section plane parallel to said support plane S, the second projecting portion 20 exhibits a trapezoidal section, in particular an isosceles trapezium section.
  • said angle b is equal to 45 degrees.
  • said second recess 26 comprises a pair of rear side chamfers 34, inclined by an angle b' relative to the symmetry plane W, symmetrically arranged relative to the symmetry plane W.
  • said rear side chamfers 34 are parallel to the front side chamfers 32 of the second projecting portion 20, that is, angle b' is equal to angle b, so that on the whole, the second recess 26 is counter-shaped relative to the second projecting portion 20.
  • Such blocks 4 are therefore stackable on one another relative to both the prevailing direction X and to the longitudinal direction Z.
  • the counter-shaping of the projecting portions 18,20 relative to the respective first and second recesses 24,26 it is possible to stack up a plurality of blocks to form a wall, inserting each second projecting portion 20 of a block into a second recess 26 of an adjacent block along the prevailing direction X, as well as inserting each first projecting portion 18 of a block with the first recess 24 of an adjacent block along the longitudinal direction Z.
  • suitable constraining means are inserted between the blocks, preferably liquid concrete or adhesive for masonry, so as to ensure the coupling stability.
  • the soundproofing material that makes up the blocks according to the present invention is a mix substantially comprising concrete, fibres and rubber.
  • the percentage by weight of concrete does not exceed the value of about 7-8%.
  • the fibres are high resistance glass fibres, having average length of about 18-20 mm.
  • said glass fibres are fibres marketed with the trade name Anti-Crak TM by ⁇ Saint-Gobain'. Said fibres are contained in a percentage by weight of about 5%.
  • the rubber advantageously consists of tyre scrap grains, preferably having an average diameter comprised between 2 and 4 mm.
  • the percentage by weight of the grain in the compound is about 90%.
  • Such process comprises the step of forming a mix based on concrete, fibres and tyre scrap grains.
  • the mix is then mixed with water in a mixer.
  • the resulting mix is gathered in a hopper and delivered to a block-shaped die, that is, the mix is cast in a die shaped as the blocks according to the invention.
  • the mix is compacted by shaking, that is, imparting vibrations to the die.
  • the mix is pressed so as to consolidate the mix into the die.
  • the mix is withdrawn and the block is dried for about 3-5 hours.
  • the glass fibres substantially soft, twist about the rubber grains, thus forming highly resistant reticular structures.
  • the soundproofing block according to the invention allows overcoming the disadvantages of the prior art soundproofing blocks.
  • the soundproofing block exhibits a high soundproofing power.
  • this high soundproofing power is due to both the particular geometry of the block and to the material of the block.
  • the staggered position of the units of the blocks, as well as the presence of internal inclined walls have the effect of creating irregular surfaces that reflect the sound waves, preventing the transmission of the same through walls made up of such blocks.
  • the soundproofing block according to the present invention is inexpensive to manufacture.
  • the block is manufactured with recycled material, in particular rubber from second-hand tyres, and the manufacture of the same is carried out through a single casting of liquid material in a counter-shaped die relative to said soundproofing block.
  • the block is entirely made of soundproofing material, the soundproofing power thereof is particularly high.
  • the sound waves do not meet masonry portions or tiles containing cores of soundproofing material therein.
  • Such portions form sound bridges and cause resonance that in the block of the present invention, entirely made of soundproofing material, are eliminated.
  • the blocks according to the present invention are entirely made of soundproofing material having a high specific weight, higher than the specific weight of the masonry or of the ceramic forming the tiles normally used.
  • the relative soundproofing power increases accordingly.
