Definitions

  • the invention relates to a flooring loose lay element, in particular a prefabricated element with an upper portion made of a ceramic and/or stone material, for example ceramics, vitrified stoneware, granite, marble, etc, and a lower non-slip surface that is able to adhere to a floor foundation.
  • a ceramic and/or stone material for example ceramics, vitrified stoneware, granite, marble, etc.
  • the invention can be applied to lay ceramic floors, for example of the low thickness/pressed or standard type, in which the floor comprises a plurality of these prefabricated elements.
  • the elements can be used to make floors in both indoor and outdoor environments.
  • the prior art comprises so-called floating floors, i.e. modular floors that are made by assembling a plurality of elements above a levelled flat surface, for example a cement screed or a levelled pre-existing floor.
  • prefabricated elements are known having foundations with a removable adhesive strip for assembling LVT (Luxury Vinyl Tile) vinyl flooring.
  • Floating floors have become very widespread. They indubitably have the advantage of offering rapid laying, without the use of glues, of being applicable to existing floors or levelled screed. This means that such floors are widely used above all in renovation work of environments because they make the floor installation work less invasive, faster and cheaper.
  • One object of the invention is to provide an element for floors that can be laid stably on a floor foundation and can be removed from the foundation after laying without causing any damage.
  • One advantage is to enable one or more elements of the floor to be removed without damaging the individual elements and/or the rest of the floor and/or the foundation.
  • One advantage is to enable even a single floor element to be removed and/or replaced easily and practically.
  • One advantage is to make a flooring loose lay element that can be laid on a foundation without the need for glues.
  • One advantage is to be able to lay rapidly and easily a floor made of ceramic or stone material (ceramics, vitrified stoneware, granite, marble, etc). [0010] One advantage is to enable a floor to be laid that is made of ceramic or stone material that does not require the application of adhesive.
  • One advantage is to make a floor made of ceramic or stone material (ceramics, vitrified stoneware, granite, marble, etc), in which it is possible not to grout the gaps after laying the floor without glue.
  • One advantage is to enable a ceramic floor (or floor made of granite, marble or another ceramic or stone material) to be laid without generating dirt (for example due to the use of adhesives).
  • One advantage is to give rise to a loose lay ceramic (or granite, marble etc) floor that can be dismantled (wholly or partially) very quickly and without requiring masonry work.
  • One advantage is to make available a ceramic floor (or a floor made of granite, marble or another ceramic or stone material) that enables even a single damaged or discoloured prefabricated element to be replaced easily and cheaply, in particular significantly limiting (compared with the retiling of a ceramic tile floor) both labour costs and the costs of the replacement material.
  • One advantage is to enable a ceramic (or granite, marble etc) floor to be obtained that is provided with the typical benefits of floating floors.
  • One advantage is to offer a prefabricated loose lay element that is suitable for replacing a ceramic (or granite, marble etc) tile, of traditional type intended for laying by glue, to make a floor.
  • One advantage is to provide a flooring loose lay element made of ceramic or stone material provided with limited thickness, for example similar to a thickness that is typical of a ceramic tile.
  • One advantage is to provide a prefabricated flooring loose lay element that is relatively uncomplicated and costly to produce.
  • One advantage is to make a prefabricated element that is suitable, like ceramic tiles, for coping with the high volumes requested by the market.
  • One advantage is to obtain a prefabricated element for floors provided with high mechanical resistance, in particular to shocks and/or impacts on the floor. [0022] One advantage is to ensure non-slip fixing of the floor elements, avoiding, in particular, side movements thereof.
