Definitions

  • the present invention relates to a mat for the dry laying of floors made with substantially plate-like ceramic articles, the related method for dry laying a floor, and the floor thus obtained.
  • ceramic articles of the type of tiles and slabs of various formats and dimensions, are generally used to provide floors using methods of adhesive bonding to the surface to be covered, with glues, resins or putties.
  • Such systems generally entail manufacturing specially-designed articles that have supports or frames with systems for interlocking, or specially-shaped regions on the laying face or on the perimetric edge that are adapted to be coupled with joining elements.
  • a system that entails covering the surface to be paved with a compressible polymeric mat covered above with a first layer of fabric on which ceramic articles are placed that are reinforced on the laying face with steel sheets that are covered underneath with a second layer of fabric, the first and the second layer of fabric being adapted to provide a tear-away connection (in the manner of Velcro®) between the mat and the articles.
  • Such system also entails the need to produce dedicated articles for the installation, with the drawbacks mentioned above.
  • the high compressibility of the mat entails the risk that the articles resting on the mat tend to move, with consequent risk of breakage.
  • floor surfaces made with different materials such as parquet, laminates or luxury vinyl tiles (LVT)
  • methods are known of dry laying on mats that are generally made of polymeric material.
  • the aim of the present invention is to eliminate the above mentioned drawbacks, by providing a mat for the dry laying of floors made with substantially plate-like ceramic articles, as well as a related method for dry laying a floor and a floor thus obtained, which make it possible to provide floors simply and rapidly using articles that are already available on the market, without requiring modifications thereto either during production or during laying, and without particular limitations on the formats that can be used.
  • an object of the present invention is to obtain adequate characteristics of mechanical resistance to impacts and to compression of the floor, as well as stability of the ceramic articles, so as to avoid the breakage thereof.
  • Another object of the present invention is to provide a mat for the dry laying of floors that it can be applied both on existing floors, preserving the integrity thereof, and on screeds to be finished, in residential or commercial spaces, indoors or outdoors.
  • Another object of the present invention is provide a mat for the dry laying of floors that offers optimal characteristics of thermal conductivity, impermeability and acoustic insulation.
  • Another object of the present invention is to provide a mat for the dry laying of floors that offers a reduced thickness of the floor obtained, thus facilitating the execution of renovation work on existing floors.
  • Another object of the present invention is to provide a mat for the dry laying of floors that makes it possible to simplify and speed up the installation operations, moreover allowing the removal and substitution of the ceramic articles, immediately or at a later time. In this manner it is possible to reuse both the mat and the ceramic articles, in similar or different spaces.
  • Last but not least, another object of the present invention is to provide a mat for the dry laying of floors that has a simple structure which is easy and practical to implement, safe in use and effective in operation, and of low cost.

  • the reference numeral 1 generally designates a mat for the dry laying of floors made with substantially plate like ceramic articles. ft should be noted that with the wording “dry laying” is meant a method for providing floors via the simple superimposition of elements, without the interposition of glues or adhesive materials in general.
  • the mat 1 consists of a substantially parallelepiped body of which two dimensions (length and width) far exceed the third dimension (thickness) and which therefore has a first and a second main surface, respectively 2 and 3, which are mutually parallel and mutually opposite, and which have an extension far exceeding that of the others.
  • the thickness of the mat 1 is generally comprised between 1.1 mm and 2.0 mm, preferably 1.5 mm, while the width and the length of the mat can have various measurements.
  • the mat 1 can have a longitudinal extension, such that it can be supplied in the form of rolls; alternatively it can be supplied in the form of panels.
  • the mat 1 comprises at least one layer of composite material 4 which comprises a polymeric matrix 5 in which an inert mineral filler 6 is dispersed.
  • the layer of composite material 4 extends between the main surfaces 2 and 3 of the mat 1.
  • the layer of composite material 4 occupies most of the overall thickness of the mat 1.
  • the polymeric matrix 5 comprises at least one among polyurethane (PU), polyethylene terephthalate (PET), polyethylene (PE) or extruded expanded polystyrene (XPS).
  • PU polyurethane
  • PET polyethylene terephthalate
  • PE polyethylene
  • XPS extruded expanded polystyrene
  • the layer of composite material 4 comprises a percentage by weight comprised between 15% and 30% of the polymeric matrix 5.
  • the chemical/physical characteristics of the polymeric matrix 5 are such as to give the layer of composite material 4 anti-skid properties adapted to impede movements on the horizontal plane of the ceramic articles, without using adhesive materials in the composition of the mat 1.
  • such ceramic articles rest directly on the layer of composite material 4 and the application of adhesives or other adhesive materials is not envisaged.
  • the ceramic articles are kept adherent to the mat 1 by their own weight.
  • Advantageously by exerting a traction it is possible to lift the ceramic articles in order to carry out repositioning or substitutions.
  • anti-skid properties of the mat 1 remain unaltered over time, allowing the substitution of the articles without intervening on the mat 1, and the reuse of the materials employed.
  • the inert mineral filler 6 comprises either or both of barium sulfate or calcium carbonate.
  • the at least one layer of composite material 4 comprises a percentage by weight comprised between 70% and 85% of the inert mineral filler 6.
  • the inert mineral filler 6 is in loose form, i.e. it is constituted of particles that are not mutually aggregated and have variable dimensions, and it is preferably in the form of powder.
  • inert mineral filler 6 increases the mechanical strength and reduces the compressibility of the layer of composite material 4 with respect to a purely polymeric material or to a composite material with a smaller quantity of inert mineral filler, giving the mat 1 adequate characteristics to support the ceramic articles and to obtain floors with good resistance to shock and to compression.
  • the thermal conductivity characteristics of the mat 1 also improve, thus making it particularly suitable for temperature-controlled floors.
  • the mat 1 is preferably provided with a removable protective cladding 7, which is associated temporarily with the at least one layer of composite material 4.
  • the presence of the protective cladding 7 makes it possible to produce the mat 1 in the form of a ribbon rolled onto itself, or of panels that can be stacked for storage, and it can be walked on during installation until the cladding itself is removed.
  • the protective cladding 7 is constituted by a layer made of polyethylene terephthalate (PET) or polyethylene (PE), paired with a layer of silicone on the face that is adapted to adhere to the at least one layer of composite material 4.
  • PET polyethylene terephthalate
  • PE polyethylene
  • the protective cladding 7 has a thickness comprised between 15 pm and 25 pm, preferably 20 pm.
  • Such protective cladding 7 is intended to be removed when the mat 1 is laid, so that the ceramic articles are resting directly on the first surface 2 of the layer of composite material 4.
  • the mat 1 is preferably provided with an anti-friction film 8 which is stably associated with the at least one layer of composite material 4.
  • the presence of the anti-friction film 8 makes it possible to facilitate the positioning of the mat 1 on the surface to be covered with this film resting on the surface, in that it allows the mat 1 to slide on the surface to be covered.
  • Such anti-friction film 8 comprises a ply of polyester (PL), polypropylene (PP) or glass fibers.
  • the anti-friction film 8 has a weight per unit of surface of the order of magnitude of 30g/m 2 .
  • the method for dry laying a floor on a surface S to be covered comprises the following operating steps:
  • the quantity of mat 1 to be supplied varies in relation to the superficial extension of the surface S;
  • the mat 1 is supplied in roll form, as shown in Figure 4, the portions are cut to measure directly during installation. If the mat 1 is supplied in the form of panels, these are placed side by side to cover the surface S, and are cut as needed;
  • the ceramic articles 10 are positioned resting directly on the layer of composite material 4, placing them side by side, and without interposing adhesives or other adhesive materials.
  • substantially plate-like is meant that the ceramic articles 10 are constituted by bodies that are parallelepiped in shape, with two dimensions (width and length) far exceeding the third dimension (thickness) so as to define two main and mutually opposing surfaces that have a greater extension, of which one is for laying, adapted to adhere to the mat 1, and the other one is decorative, adapted to remain in view after laying.
  • the shape and the plan dimensions of the ceramic articles 1 used can vary as a function of the needs of the specific application.
  • Such ceramic articles 10 are generally quadrangular in plan view.
  • the ceramic articles 10 used are of the type of ceramic slabs that are rectangular in plan view and have a thickness comprised between 3 mm and 30 mm.
  • the ceramic articles 10 are of the type already available on the market and each one comprises a slab 11 of ceramic material that comprises stoneware and a reinforcement layer 12 that comprises glass fibers and polyurethane adhesive material ( Figures 2 and 3).
  • the operating step of juxtaposing can consist in arranging the plurality of ceramic articles 10 so that the corresponding perimetric edges are in contact in pairs spaced apart so as to define gaps 14 interposed between the articles.
  • the spaced-apart positioning of the ceramic articles 10 can be carried out with the aid of conventional spacer elements 15, known as tile spacer crosses ( Figure 5).
  • the method also comprises the step of filling such gaps 14 with sealing material, covering the spacer elements 15 interposed between the ceramic articles 10 ( Figure 6).
  • the method also comprises the step of filling such gaps 14 with sealing material, covering the spacer elements 15 interposed between the ceramic articles 10 ( Figure 6).
  • the sealing material used can be of the type of acetic silicone, neutral silicone, epoxy putty, cement-based putty or ready-to-use grouting based on polymeric dispersion, mineral fillers and additives and can be applied using working methods that are known to the person skilled in the art.
  • the sealing material used is of the type of acetic or neutral silicone and can be applied with the aid of a conventional nozzle 16.
  • the use of silicone favors the possibility of removing and optionally reusing the ceramic articles 10.
  • the operating step of juxtaposing can consist in arranging the plurality of ceramic articles 10 so that the corresponding perimetric edges are in contact in pairs ( Figure 7).
  • the ceramic articles 10 are held in the correct position, not only by the anti-skid effect of the layer of composite material 4 of the mat 1 , but also via the application of the sealing material (a floor with gaps) or the simple contact of the articles themselves (a floor without gaps).
  • the method according to the invention entails, preliminarily in the covering step, carrying out a step of verifying the flatness of the surface S and an optional step of leveling the depressions of the surface by the superimposition of sheets made of plastic material.
  • a leveling of the surface S can be carried out using traditional systems known to the person skilled in the art.
  • the floor 13 obtained using the method described above comprises, therefore, the anti-friction film 8 (if present) resting on the surface S to be covered, paired with the upper layer of composite material 4 and the ceramic articles 10 superimposed on that layer.
  • the invention makes it possible to use ceramic articles that are available on the market, without requiring modifications thereto either during production or during laying.
  • the invention is also flexible in use and makes it possible to obtain floors that last over time, moreover offering the possibility to reuse the materials used.
