Definitions

  • the present invention relates to a method for the dry installation of coverings -in particular floors- made from natural materials (marble, granite, or stone), agglomerated stones, or other.
  • installation and “laying” mean all the operations performed to lay a covering onto a pre-existing structure, either internal or external, using appropriate products or fixing systems.
  • Installation methods based on metallic anchorage of slabs, which anchoring systems can play a role of simple fixing to the supporting wall, or can act as bearing structure, and methods based on an air space between slabs and walls of the structure (ventilated facade) are known and are not part of the present invention.
  • floors and walls are complex (multi-layer) building systems and that these systems as a whole, not only the coverings, are environment- sensitive and must be able to withstand mechanical, chemical and hygrometric stresses.
  • the considerations to be taken into account during installation are therefore linked to a classification of the surfaces to be covered.
  • the significance of this classification lies in the fact that to each environmental typology corresponds a different stress level.
  • a correct choice of the installation system cannot leave out of consideration the characteristics and the behaviour of the structure to be covered.
  • the present state of the surfaces to be covered and to evaluate the need for any pre-treatments ; the dimensional variations the structure components might undergo; the physical- mechanical properties of the structure-forming materials and the composition and distribution of joints.
  • the surface shape is also important, because it can influence the choice of the size of the covering material, its arrangement and installation technique (open joint/closed joint).
  • the surface size may require the insertion of some dilatation joints and the overall thickness of the covering may influence the choice of the installation system (thick or thin layer).
  • the way and the quality of the installation may give rise to dangerous conditions due to an incorrect evaluation of the properties of the covering materials in respect of the environment, or to problems due to tensional states between covering and screed.
  • the presence of a binding layer makes it possible to chose the material and the installation system only after having defined all the data of the project.
  • the choice of the covering material must be made not only on the basis of aesthetic characteristics, but also of the performances declared by the manufacturer; these performances affect the covering size, which, in turn, gives elasticity or stiffness to the covering layer.
  • the binding material In the case of installation by adhesive, the binding material must meet the following requirements: allow firm and tight anchorage between the upper and lower layer, have a compact structure, have elastic/plastic characteristics able to withstand any movements or deformations of the supporting layer.
  • the binding layer affects all the characteristics of the covering.
  • the numerous installation methods by adhesives can be divided into two main categories: the so called traditional installation methods with cement mortar (which require laying a mortar bed 4-5 cm thick) and installation methods with adhesive (which require applying a thin layer about 2-5 mm thick).
  • the latter can be further subdivided into two categories, depending on whether adhesives based on cement or adhesives based on organic substances are used.
  • Traditional installation methods with cement mortar require the use of a binding material (cement) and an inert fraction (sand), thoroughly mixed and added with water. The problems experienced with these methods depend in general on high water/cement ratios, incorrect amounts of cement and use of lime in partial or total replacement of cement.
  • cement-based adhesives can also be used, i.e. pre-dosed cement mortars marketed in the form of powder, to be mixed with water upon use. They are made of cement, sand, resin and other additives, whose main function is to increase both water retention power and adhesion. In general, from the technical point of view, these types of adhesives are not very different from traditional mortars and share the same mechanical brittleness. Other drawbacks are poor elasticity and limited adhesion.
  • Organic-based adhesives are of two types: ready-to-use paste adhesives, i.e. premixed water dispersions of various type (acryl, vinyl, etc.), mineral fillers and additives; two-components adhesives to be mixed upon use, based on synthetic resins (epoxy or polyurethane resins or other) with suitable hardeners. All organic-based adhesives are characterized by good elasticity, therefore they are necessary for applications where differential movements between screed and covering are expected, or in environments particularly subjected to hygro-thermal variations (for example in outdoor coverings). The main drawback is their high cost.
  • Object of the present invention is to overcome the above mentioned drawbacks; in more detail, the object of the invention is to provide an installation method for coverings that does not require continuity among the layers and at the same time makes the covering stable and long-lasting after installation. A further object of the invention is to provide an installation method that can be carried out easily and in short times, without skilled workers.
  • the invention also concerns the elements used in the installation method, in particular the tiles of independent claim 13, and the module comprising several tiles of claim 12.
  • more tiles are joined together to form a panel before laying them onto the screed. This assembling is possible because, after cut-to-size operations, the four tile sides are worked so as to create grooves and protrusions that allow permanent locking.
  • the dimension of the tiles is not subject to limitations; the only limit is imposed by the need to handle the panel once the tiles are assembled.
  • the thickness of the tiles can range from 8 to 30 mm, but is preferably not lower that 12 mm, in order to allow perimeter finishes.
  • the tiles can be bevelled or not and their upper surface can be either polished or honed.
  • the invention further relates to a process for the dry installation of coverings of pre-assembled modules, which does not require the use of cement mortars, organic-based adhesives, or inorganic binders.
  • the main advantages of the process are savings in adhesives, easy installation (skilled workers are not required), and short installation time, which is reduced to the mere positioning of panels prepared in advance by inter-locking more tiles until reaching the desired surface dimensions.
  • dilatation joints are still necessary to release the covering from the fixed elements of the building and allow small relative movements, divide large surfaces in smaller ones and interrupt the covering in correspondence of discontinuities in the supporting layer.
  • the screed must be prepared properly, by covering it with a compensative layer which could be made of a thin polyurethane mattress, a non-woven polyester fabric, a suitable bituminous membrane, or else.
  • a compensative layer which could be made of a thin polyurethane mattress, a non-woven polyester fabric, a suitable bituminous membrane, or else.
  • an insert or a pin of a suitable material can be introduced in the tiles.
  • a thin layer of a suitable adhesive can be applied to tile sides.
  • the panels can be of different dimension and shape, according to the expected thermal stress from the environment; dimension and shape should also allow easy handling.
  • the covering can be finished with conventional methods, by filling the joints with suitable materials having sufficient elasticity to allow it to settle after installation.
  • the attached drawings show some possible embodiments of tiles suitable for carrying out the installation method of the invention.
  • fig. 1 (A) and (B) schematically show two possible interlocking couplings between tiles
  • fig. 2 (A) and (B) schematically show two possible tiles junctions using inserts or coupling pins
  • fig. 3 shows, with size references, an example of covering made with the tiles of fig. 2 (A).
  • reference numbers 1 and 2 indicate tiles which fit together to form a covering panel of appropriate dimensions.
  • each tile has a groove or hole 3, 4, of rectangular, in particular square, or semi-cylindrical shape, suitable for housing an insert 5, of rectangular or circular section, respectively, which allows to join the tiles together.
  • the fitting elements may have different shapes.
  • a bevel 6 is cut on the upper edge of the tiles.
  • tiles 1 and 2 should be worked on their sides so as to form grooves 3, 4 having a depth of 4 mm and a height of 4 mm.
  • the distance between the groove and the tile edge could also be of 4 mm.
  • the distance between the groove and the lower bevel is 3.5 mm.
  • Interlocking between tiles is secured by a strip-shaped insert 5, for example in polyurethane material, 10 mm large and 3.6-3.8 mm thick (anyway smaller than 4 mm). The longer size of the strip should allow the tiles to settle onto the supporting layer at a reciprocal distance of 2 mm.
  • modules formed by two or more tiles can be pre-assembled and laid down without the use of adhesives, over a mattress positioned on the screed.
  • the modules can have different dimensions, and can measure one square metre or more, according to the number of dilatation joints to be inserted in addition to those present along the tile perimeter, for example near the walls, according to the expected temperature changes in the room in which the covering is to be installed.
