Definitions

  • the invention relates to a method for providing tiles, which are burned in a combustion chamber with spacers, whereby the spacers after firing the tiles as a mass of material made of plastic on the edges of the tiles, as well as a production plant for the industrial provision of Tiles with spacers according to this procedure.
  • Floor or wall tiles are known, the side edges of which with spacers, i.e. cam-like or web-like spacers, are provided in order to lay the tiles in a flat tiling between the respective tiles maintain an adequate joint.
  • spacers i.e. cam-like or web-like spacers
  • the shapes for Pressing the tiles in the area of the spacers so that the spacers directly when making the tiles are integrally formed with.
  • the tiles including the molded spacers are, however, for reasons of formability only possible if the later surface of the tile during molding in the area of the bottom of the corresponding mold is provided.
  • the tiles provided with spacers in this way are kept in stock until they are used.
  • the invention described in more detail below relates especially on tiles that are vibrated using a or vibration method for tiling floors become. With such a laying of the tiles first spread a mortar over the area to be laid, on which the tiles are then laid. Then is the actual vibration process with the help of vibration machines performed by these vibration machines the Press the tiles into the laying mortar. Through the vibrating process it is possible to create floors that are extremely high loads, for example by driving over heavy vehicles, can be exposed without the tiles loosen.
  • Tiles are known from DE 24 54 882 A1 which are used as facade elements with the help of so-called shock tables. Thereby the tiles with their later outside inserted into a formwork shape that corresponds to the size of the later facade element corresponds.
  • the tiles must be on be precisely aligned with the bottom of the formwork by hand, as they are poured with wet concrete after alignment and therefore no access and alignment option there is more on the tiles.
