Definitions

  • This invention concerns a procedure for obtaining cement tiles or panels . More in particular, .this invention refers to a procedure for obtaining' tiles or panels which have a structure that allows them to be used to construct raised floors or covering. .
  • This procedure is used for the production on an industrial scale of .panels or sheets made from conglomerate material, in particular a material generally consisting of cement, marble and/or quartz and/or sand and/or granite-based mixtures, also comprising possible intrusions of various kinds, such as metal elements, glass, wood, etc.
  • This invention also refers to a die which can be used on a machine to obtain cement tiles or panels, equipped with several stations for carrying out a complete and. automatic work cycle. Finally, the invention refers to - a cement tile or panel advantageously obtained according to this procedure and with this die.
  • the invention applies mainly to the industrial processing field of 'marble, stone, granite and the like.
  • This procedure comprises the following processing stages : - crushing of the- inert stone material; preparation of a mixture consisting of water, crushed material and inert cement sand binders; preparation, in a pressing die, of a plastic frame inside which a wire-mesh reinforcement is positioned; - batching of this mixture inside the die; pressing -of . the mixture in order to obtain a tile presenting a predetermined configuration - and predetermined dimensions, this pressing being carried out by means of a punch-holder shaped block, positioned in operation above the die, designed to support a plurality of punches . which penetrate the mixture between the links of the wire-mesh; extraction of the tile from the press and subsequent curing of the tile.
  • a procedure such as- the one described above makes it possible to obtain cement " tiles or panels with precisely predetermined lengths, widths and thicknesses, and is performed in a continuous process on a specially designed plant.
  • One disadvantage of this procedure is the need to foresee the presence of a synthetic or metal frame to support the wire-mesh reinforcement, thus making the procedure more complex and the costs of each tile or panel higher.
  • This invention proposes to overcome the drawbacks present in the background art. Improvements to the . basic procedure described above have therefore been made, and in -particular it has been made possible- to eliminate the wire-mesh support frame. This makes the procedure more rapid and more simple, and the resulting tile more economical.
  • a dispenser is used between the mixing phase and the pressing and compacting phase, designed to pour predetermined quantities of crushed material into an appropriate die in order to give it a predetermined configuration, for example square, rectangular or in any case polygonal.
  • tiles are obtained that are inert from a mechanical and electrical point of view, being free of resinous material and using only cement as a binder. In this way the tiles are completely fire-proof and can therefore be classified as "class zero".
  • cement tiles are, particularly suitable- for floating or raised floors, which generally present a reticular frame designed to support panels above the ground in order to construct ' a hollow space designed .to house electrical and/or hydraulic ducts .
  • this invention proposes to provide a die which can be used in cooperation with a machine to produce cement tiles or panels according to this procedure.
  • this invention proposes to provide a cement tile or panel with a relatively limited thickness and at the same time good mechanical resistance so as to offer a high degree of . flexibility during laying, thereby ' limiting risks of cracking.
  • This tile or panel is the subject of claim 7.
  • the dependent claims describe advantageous embodiments . of the invention.
  • the procedure for the production of cement tiles or panels according to this ' invention foresees : - crushing of the various materials making up the conglomerate; preparation of a mixture consisting of water, crushed material and inert cement sand binders; a first batching of the mixture inside a pressing die until a part of the die is filled; , positioning, on top of the material poured into the die, of a wire-mesh reinforcement; a second batching of the mixture, into the die, to cover the wire-mesh reinforcement; - pressing of the mixture in order to obtain a tile with a predetermined shape and predetermined dimensions; extraction of the tile and its subsequent curing.
  • the pressing is achieved by means of a shaped block, positioned in operation above the die, designed to support a. plurality of punches which penetrate the mixture through the links in the wire mesh.
  • the die for the production of tiles is part of a plant already known and used in this particular sector; as such, the die is shaped with sloping walls.
  • the tile produced in the die will also have side walls which slope inwards at a predetermined angle from the visible surface of the tile. Tiles or panels are thus obtained which are extremely easy to lay, reducing the thickness of the joints and avoiding the risk of breakage during laying.
  • figure 1 shows a perspective view, slightly from above, of a tile according to the invention
  • figure 2 shows a plan view from below of the tile according to figure 1
  • - figure 3 is a front elevation of the tile according to the invention, in which some internal details of the tile are shown.
  • the procedure according to this invention is carried out by using an automated control machine already known in the sector, controlled by a specific electronic .unit whiph manages the entire" production cycle of the tiles or panels.
  • the tile or panel 10 .according to the invention is made from inert conglomerate material with an internal wire-mesh reinforcement 12, its base surface 15, not visible when laid, presenting a plurality of cavities 17 corresponding to the links of the wire mesh.
  • the procedure for obtaining tiles or panels 10 according to the invention foresees: crushing of inert stone material; - preparation of a mixture consisting of water, crushed material and inert binder cement sand; batching of a first predetermined quantity of this mixture inside a pressing die (not shown in the figures ) ; - positioning, inside the pressing die, above the first predetermined quantity of the mixture, of a wire-mesh reinforcement 12; batching of a second predetermined quantity of the mixture inside a pressing die; - pressing of the mixture in order to obtain a tile 10 with a predetermined shape and predetermined dimensions, this pressing being- achieved by means of a shaped block, positioned above the die, designed to support a plurality of punches which penetrate the links of the wire mesh 12; extraction of " the ' tile 10 from the press and subsequent curing of the tile.
  • the shape of the pressing die. is such that the tile formed inside it has side walls 11 (see fig. 3) which slope slightly inwards, for example at an angle between 2° and 8°, starting from the visible surface 13, when laid, of the tile 10.
  • the shape of the die with slightly sloping walls thus makes it possible to obta-in tiles which are extremely easy o lay, particularly in the case of laying raised floors (floating floors).
  • the procedure is then transferred, by means of a conveyor for example, to other machine tools in order to carry out the usual finishing processes, for example polishing.
  • the machine can be equipped with sensors and/or transducers connected to an electronic control unit designed to manage the production cycle on a continuous basis.
