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.
  • DE 198 04 322 A1 discloses a perforated brick with an at least one-sided cover layer made of a mortar layer, with which the perforation of the brick is closed and a predetermined stone height can be achieved. From German published patent application DE 100 19 265 A1, a method and a device for the production of perforated bricks with a hole closure on the bearing surfaces is known, in which the perforated brick gets a hole closure on this storage surface by pouring dry mortar with subsequent moistening.
  • Closing the holes along a bearing surface has advantages in that it creates a surface for the application of mortar.
  • the disadvantage is that such a stone must be placed in the correct position and accordingly It should also be delivered and transported as suitably as possible that the outer closure layer is susceptible to injury and prone to breakage during transport and handling, and that the bearing surface provided with such a cover layer provides an inconsistent picture compared to the other stone, which in particular in the case of imperfect and damaged hole closures, also if these functionally required barriers are irrelevant, traffic will not accept them due to this optical effect.
  • this object is achieved with a method according to claim 1 and an artificial stone according to claim 13.
  • the method creates a possibility, which can be easily added to the production process of perforated artificial stones, in particular perforated bricks, and which can be realized with reasonable effort, to produce inner and thus "hidden" hole closures which leave the stone with its conventional external appearance and also its location-independent handling and great robustness.
  • the mortar sealing material and with the addition of water for hydraulic setting materials and techniques of familiar and proven form result. Hole closures in a central region of the stone at varying heights are particularly advantageous, which prevents the formation of continuous thermal and acoustic bridges at the same level.
  • the perforated closures on the inside can easily be specified as thin-walled, since they are not mechanically stressed in the protected inner layer and because a certain proportion of defective perforated closures is not critical. can be taken as long as appropriate closures against the formation of long "organ pipes" can only be expected in the (vertical) sequence of perforated stones.
  • FIG. 1 side view of a perforated brick
  • FIG. 2 top view of the perforated brick according to FIG. 1,
  • Figure 3 a device for producing hole closures in
  • FIG. 4 and FIG. 5 scatter masks for a device according to FIG. 3 and FIG. 6: perforated bricks with internal hole closures.
  • a perforated brick generally designated 1 in FIGS. 1 and 2, has a cuboid outline with smooth vertical side walls 2 and 3 and with side surfaces 4 and 5 profiled in the sense of interlocking abutting surfaces of adjacent stones, while in the usual bricked-up position storage areas above and below Chen 6 and 7 in the whole plane but are interrupted with a variety of different perforations 8, which in the conventional perforated brick, as cut from the strand as a blank and then hardened by firing, pass vertically from one of the bearing surfaces 6, 7 to the other.
  • these holes 8 are to be closed off by internal hole closures 9, as can be seen in the vertical section through the perforated brick 1 according to FIG. 6.
  • a device designated overall by 10 in FIG. 3, in which perforated bricks 1 are continuously placed on the upper run of a circumferential, flatly closed conveyor belt 11 and move in the direction of an arrow 12 under pouring containers 13 and 14 and a water container 18.
  • the bulk container 13 is equipped with a free-flowing bulk material, preferably sand. It goes without saying that other free-flowing materials are also possible, especially since this material is only used up to a small extent and is largely reused / used. Depending on the brick material and the place of manufacture, sawing or grinding dust from fired bricks can be used.
  • a cellular wheel sluice 19 at the bottom in the storage container 13 regulates and doses the amount of filler material to be sprinkled on the perforated brick that is going through and which is to fill the brick up to a central area, but with a changing height.
  • the amount of material remaining in the upper bearing surface 7 of the perforated brick between the perforations 8 is at least largely swept into the holes 8 by a stripper 20 following the bulk container 13.
  • the scraper 20 is designed here in the form of a fixed brush. It goes without saying that whose scraper devices including motorized scraper brushes can be used.
  • the stripping process already results in different filling heights, since in view of the different surface distributions between perforations 8 and adjacent webs, different amounts of filling material are swept into the holes 8. This is quite advantageous and is also sought.
  • the cellular wheel sluice can be controlled alternately depending on the feed of the respective stone, so that the fill level in the stone varies.
  • the bulk container 13 can be equipped on the underside with a scatter mask 21 according to FIG. 4 or a scatter mask 22 according to FIG. 5, which extends in the mouth of the bulk container 13 transversely to the direction of movement according to the arrow 12 and varies the spreading quantity transversely to the direction of advance.
  • the bulk container 14 stores dry mortar, which is also sprinkled on a metering device 23 in the form of a rotary valve on the stone passing underneath and is inserted into the holes 8 with the aid of a scraper 24.
  • the amount of dry mortar applied is normally narrow, so that only a dry mortar layer of 1-10 mm, preferably 1-3 mm, is applied.
  • the bulk containers are assigned a vibrating device 25 which is fundamentally known and also largely of any type, and which compacts the filling material and also the closure material.
  • the perforated bricks 1 subsequently pass through a moistening station the water tank 18, which is equipped on the underside with controlled nozzles or dispensing tubes 17, which are aligned with the hole pattern of the stone 1 and accordingly bring in a targeted and controlled manner the amount of water required for the hydraulic setting of the mortar into the holes 8.
  • the mortar can be a quick-setting mortar with corresponding known components such as "lightning cement” or “Portland cement” and also a setting accelerator.
  • a device is preferably provided directly after a brick production, in which the temperature of the perforated brick, which is still warm from the firing, accelerates the solidification process.
  • the bricks 1 are then conveyed with suitable means over a sieve or grid area 26 so that the filler material sand, as long as it does not adhere to the sealing layer formed in the stone with the hardened mortar, can drop downwards in order to be collected in a collecting container 27 , from where it is to be fed back to the bulk container 13.
  • FIG. 6 shows in an enlarged view the basic structure of the perforated brick 1 achieved thereby with the internal hole closures 9, which generally do not have to or should not be arranged in the center, but should only have a sufficient distance from the bearing surfaces 6 and 7 so that they are neither optically appear mechanically in the area of the bearing surfaces.
  • the hole closures 9 are offset in height from one another, that is to say vary in their height, as a result in particular, it prevents the formation of a false ceiling within the stone, in which the mortar hole closures represent a cold bridge and thus question the arithmetic insulation values of the stone and also represent a structure-borne noise bridge in terms of sound propagation.
  • the filling material such as sand or brick powder is not only readily available and inexpensive, but also uncritical with regard to residues that stick to the mortar.
  • the mortar can even be enriched to accommodate a boundary layer of mineral material.
  • material can be used which does not tend to make a contact connection with the closure material.
  • the stone with the hole closures 9 on the inside has the tried-and-tested properties - and also the visual appearance - of the conventional and valued perforated brick.
  • the perforated brick is a particularly suitable example for the use of internal hole closures, but hole closures of this type can also be used with other artificial stones.
