Definitions

  • the present invention relates to a method for producing a flat surface in use in the building sector, and to the flat surface for buildings thus obtained.
  • the invention in question is advantageously used in the building sector to produce floors or walls in general, especially foundation, of dwellings, commercial or industrial buildings or building constructions in general, to which the description below refers explicitly, however without loss of generality.
  • the floors of dwellings or buildings in general have a multi-layer structure wherein a layer of various material adapted, in use, to be facing outward and which can be walked on, such as marble, wood, terracotta, linoleum, ceramic tiles, parquet etc., is fixed to at least one layer principally in cement called foundation slab.
  • the object of the present invention is therefore to provide a method for producing a surface, such as a floor or a wall, which has optimum properties of thermal insulation, with high resistance to compression, and also having high capacities of reducing both impact and airborne noise.
  • Another object of the invention is that of producing a flat surface, such as a multi-layer floor or wall, which is produced through the use of materials that are eco-compatible and very economical, light and with low thermal coefficients, and also having high noise absorption properties.
  • a method for the production of a flat surface in the building sector, in particular a floor characterized by the fact that it comprises the steps of producing a cement layer; of laying on said cement layer at least a quantity of plastic granules to define at least a first intermediate uniform solid layer made of thermal and acoustic insulating material; and of laying on said intermediate layer an external layer made of various material.
  • the present invention is also relative to a flat surface for buildings, of the type comprising at least a first cement layer, and at least a second layer, the surface being characterized by the fact that it also comprises at least an intermediate thermal and acoustic insulating layer, positioned between said first cement layer and said second layer, and substantially comprising a solid layer made of plastic material ground into granules.
  • the letter P indicates as a whole a flat surface for buildings or dwellings in general, in particular a flat surface adapted to define a floor P.
  • the floor P has a multi-layer structure M to define a solid assembly, which comprises, from the bottom upward in the accompanying figure, a flat layer 1 or foundation slab in cement, a first intermediate layer 2 appropriately fixed (according to methods known and not described herein) to the upper part of the layer 1, a second intermediate layer 3 appropriated fixed to the upper part of the first intermediate layer 2, and an external layer 4 appropriately fixed on top of the layer 3.
  • the outer layer 4 is produced in various material adapted, in use, to be horizontally facing upward and outward, that is, to define the visible part of the floor and therefore which can be walked on, such as marble, wood, terracotta, linoleum, ceramic tiles, parquet, etc., and preferably coloured and/or provided with patterns or specific aesthetic characteristics.
  • the first intermediate layer 2 defines a first screed, very light in weight, provided with high thermal and acoustic insulating properties, very resistant to compression, and preferably formed by a base made of polymeric material, ground into granules, said base being appropriately mixed with cement, or other binding material, and water, and subsequently spread, pressed and smoothed to obtain a solid layer at least five centimetres thick.
  • the proportions of cement or equivalent binding material and water of the aforesaid mixture for forming the layer 2 preferably vary between 100 kg/m 3 and 150 kg/ m 3 ; however, it has be proven that it is advantageously possible to reach up to 400 kg/m 3 .
  • the intermediate layer 2 is formed solely of a defined base amount of polymeric material ground into granules and appropriately pressed and smoothed to obtain a compact layer.
  • said material in granules preferably includes a ground product obtained from insulating sheaths for covering electrical cables and the like, and is subjected, before assembly of the solid layer, to a cleaning step for removing metal slag (aluminium, copper, etc.) or the like, so that it contains no dangerous impurities and is regenerated for the specific purpose of complying with current strict regulations in terms of recycling plastic material.
  • This cleaning step preferably comprises feeding the material in granules through vibrating and blowing means adapted to separate and to eliminate impurities and metal slag.
  • a step for dividing the granules according to grain size the dimensions of which can vary from 0.1 to 5 centimetres.
  • this layer 2 can also be used as inert filler in cellular concrete: due to its properties it gives the slab properties of considerable thermal and acoustic insulation and light weigh.
  • the second intermediate layer 3 defines a second very light screed which, analogously to the first intermediate layer 2, has high acoustic and thermal insulating and load-bearing properties, and comprises a base of regenerated synthetic polymeric material in granules, which is mixed, also with the addition of additives and structural reinforcements, such as sand or the like, to cement and water, and subsequently spread, pressed and smoothed to obtain a solid layer at least four centimetres thick.
  • additives and structural reinforcements such as sand or the like
  • the proportions of cement and water of the aforesaid mixture for forming the layer 3 are of 250 kg/ m 3 ; however, it has been proven that it is advantageously possible to reach up to 400 kg/m 3 .
  • material in granules preferably comprises a ground product obtained from insulating sheaths for covering electrical cables and the like, and is subjected, before assembly of the solid layer, to a cleaning step for removing metal slag or the like, so that it contains no dangerous impurities for the specific purpose of complying with current strict regulations in terms of recycling plastic material.
  • This cleaning step preferably comprises feeding the material in granules through vibrating and blowing means adapted to separate and to eliminate impurities and metal slag.
  • the layer 3 can be produced using the same mixture of which the layer 2 is composed (up to 99%), sand or the like (up to 99%, with grain size from 0.6 to 6 centimetres, and/or further fibrous material (up to 10 kg/m 3 .)
  • an insulation mat 5 with lateral band 5a is laid between the layer 2 and the layer 3.
  • laying of the various layers of the structure M takes place by means of laying of the first intermediate layer 2 on top of the foundation slab layer 1 in cement, optional positioning of the mat 5 and then laying of the second intermediate layer 3, to define a flat and uniform surface that forms the load-bearing structure for the external layer 4. Laying can take place also substantially simultaneously to formation of the foundation slab layer 1.
  • the structure M of the floor P comprises the layer 1, the layer 2 and the layer 4 mutually assembled; instead, according to a further variant, again not shown, the structure M is of the type comprising the layer 1, the layer 3 and the layer 4 mutually assembled.
