Definitions

  • the invention relates to a method according to the preamble of claim 1 and an artificial stone according to the preamble of claim 13.
  • the outer closure layer is prone to injury and breakage during transport and handling and that the bearing surface provided with such a cover layer provides an uneven picture compared to the other stone, which in particular imperfect and damaged hole closures, too if these functionally desired barriers are irrelevant, will not be accepted by the traffic due to this visual effect.
  • the object of the invention is accordingly to provide a stone and in particular also a manufacturing method for such a stone, which has a large robustness and an undisturbed appearance hole closures.
  • this object is achieved by a method according to claim 1 and an artificial stone according to claim 13.
  • the method provides a the production process of perforated artificial stones, in particular of perforated bricks, easy to apply and feasible feasible way to produce inner and thus "hidden" hole closures that leave the stone its conventional appearance and also its position-independent handling and great robustness.
  • closure material mortar and with the addition of water for hydraulic bonding result in materials and techniques familiar and proven form.
  • perforated closures in a central region of the stone in varying height, which prevents the formation of heat and sound bridges at the same level at the same time.
  • the hole closures inside are readily thin-walled pretend, as they are mechanically unclaimed in the protected inner layer and since a certain proportion of defective hole closures accepted uncritically can be as long as only in the (vertical) sequence of perforated bricks with appropriate closures against training long "organ pipes" can be expected.
  • FIGS. 1 and 2 Overall with 1 designated perforated brick outer externally known form has a cuboid outline with smooth vertical side walls 2 and 3 and in the sense of a toothing of adjacent abutment surfaces of adjacent stones profiled side surfaces 4 and 5, while in the usual bricked up and down bearing surfaces 6 and 7 throughout but are interrupted with a variety of different perforations 8, which in the conventional perforated brick, as cut as a blank from the strand and then cured by firing, from one of the bearing surfaces 6, 7 to the other vertically.
  • These holes 8 are shut off according to the invention by internal hole closures 9, as in the vertical section through the perforated brick 1 according to FIG. 6 you can see.
  • FIG. 3 A total of 10 designated device provided in the top strand of a circulating, closed-belt conveyor belt 11 perforated bricks 1 are continuously placed and move in the direction of an arrow 12 under bulk containers 13 and 14 and a water tank 18 therethrough.
  • the bulk tank 13 is equipped with a free-flowing bulk material, preferably sand. It is understood that other available materials flowable type into consideration, especially since this material is only slightly consumed and largely reused. In adaptation to the brick material and the place of manufacture, for example, sawdust or grinding dust of fired bricks can be used.
  • a rotary valve 19 below in the reservoir 13 regulates and doses the lovedstreuende on the respective continuous hollow brick tile filler amount, which is to fill the brick to a central area, but quite with changing height.
  • the scraper 20 is formed here in the form of a fixed brush. It is understood that others Strippers can be used including powered stripping brushes. The stripping process already results in different fill levels, since, given the different surface distributions between perforations 8 and adjacent webs, different amounts of filler material are pushed into the holes 8. This is quite advantageous and also desired.
  • the rotary valve can be alternately controlled depending on the feed of the respective stone, so that the filling level varies in the stone.
  • the bulk container 14 stores dry mortar, which is also sprinkled via a metering device 23 in the form of a rotary valve on the passing through stone and is inserted with the aid of a scraper 24 in the holes 8.
  • a metering device 23 in the form of a rotary valve on the passing through stone and is inserted with the aid of a scraper 24 in the holes 8.
  • the amount of dry mortar applied is usually narrow, so that only a dry mortar layer of 1-10 mm, preferably 1-3 mm is applied.
  • a vibrator device 25 is generally known and also largely arbitrary type associated, which provides for a compression of the filling material and also of the closure material.
  • the perforated bricks 1 pass through a moistening station the water tank 18, which is equipped at the bottom with controlled nozzles or dispensing pipes 17, which are aligned with the hole pattern of the stone 1 and accordingly targeted and controlled bring the necessary for the hydraulic setting of the mortar amount of water in the holes 8.
  • the mortar may be a quick-setting mortar with corresponding known components such as “flash cement” or “Portland cement” and also solidification accelerator.
  • flash cement or "Portland cement”
  • solidification accelerator also solidification accelerator.
  • such a device is preferably provided directly following a brick production, in which the temperature of the still warm warm perforated brick accelerates the solidification process.
  • the bricks 1 are then conveyed by suitable means through a screen or grid area 26, so that the filler sand, as far as it does not adhere to the formed in the stone with the hardened mortar closure layer, can be omitted down to be collected in a sump 27 from where it is to be returned to the bulk tank 13.
  • FIG. 6 shows in the enlarged view of the basic structure of the achieved through hole brick 1 with the inner hole closures 9, which generally need not be centrally located or should, but should only have a sufficient distance from the bearing surfaces 6 and 7, so that they are not visually apparent still mechanically enter the area of the bearing surfaces.
  • the hole closures 9 are mutually offset in height, so vary in their altitude, which In particular, prevents a false ceiling is created within the stone in which the mortar hole closures constitute a cold bridge and thus question the mathematical insulation values of the stone and also represent a structure-borne sound bridge with respect to the sound propagation.
  • the filling material such as sand or brick dust is not only readily available and inexpensive, but also uncritical in terms of mortar-adhering residues.
  • the mortar may even be enriched to receive a boundary layer of mineral material. It is understood, however, that quite material can be used which does not tend to contact with the closure material.
  • the stone with the inner hole closures 9 has the proven properties - and also the visual appearance - of the conventional and evaluate perforated bricks on.
  • the perforated brick is a particularly suitable example for the use of internal hole closures, but can Lochver Why find this kind of other art stones quite appropriate application.
