Definitions

  • the invention relates to a brick having cavities that extend in the direction of height.
  • the mentioned method and the brick are known.
  • the individual building blocks are often carried out with tongue and groove, so that both the alignment easier than the stability is higher.
  • the tongue and groove is supported Arrangement always in such a way that the grooves and tongues in the bed joint are located.
  • the basic material is first prepared for the manufacture of bricks. For this After the extraction of the clay or clay in the opencast mine, the transport takes place for temporary storage in a swamp house. There are different types of clay mixed. Due to the storage, an even moisture and a Homogenization achieved. The mechanical processing of the clay, in particular the crushing takes place in a pan mill. Then the raw materials mixed and moistened in a desired ratio.
  • the stone blanks are shaped by extrusion. It will Material pressed through a spray head. Then individual Raw stones separated by a cutter. The shaped material comes in the dryer, which can be operated with the waste heat from a tunnel kiln. The Drying time varies depending on the format and bulk density and is usually 24 Hours. The dried blanks are then dried at approx. 1,000 ° C within 30 burned in a tunnel kiln for up to 45 hours. The residue-free combustion of the Porosity substances mentioned causes the fine porosity.
  • Standard bricks (DIN 105) can be produced using this process become.
  • Panziegel are known, which also with the above Processes can be made.
  • Planned bricks allow the creation of a Masonry, in which only a thin layer of mortar of about 1 millimeter between is applied to the rows of stones. This sets a very high dimensional tolerance of the stones ahead, so that the procedure shown is necessarily a post-processing in the form of a grinding process. This will make the stones ground to the necessary tolerance with high accuracy.
  • a disadvantage of the method mentioned is that grinding is an expensive one Is a manufacturing step that is not only capital-intensive (it must be in the appropriate Grinding systems are invested), but also the manufacturing time of the stone - and again the cost - increased.
  • Another disadvantage is that the Grinding dust is an environmental burden on the one hand and often on the other cannot be removed from the stone surface, so that the mortar bond bad is.
  • the invention is therefore based on the object of improving the known production method for bricks and at the same time eliminating the disadvantages mentioned.
  • the process should therefore work more cost-effectively and not cause exposure to grinding dust, but nevertheless produce inexpensive stones that can be installed as tarpaulin bricks.
  • a brick that can be used as a facing brick is to be created, which is distinguished from a known facing brick in that it has an improved thermal and acoustic insulation property.
  • the solution to this problem by the invention with regard to the method is characterized in that the individual bricks (1) are cut to length while maintaining a low tolerance (T) in such a way that the brick (1) is reworked to achieve a defined stone height ( H), especially by grinding, is not required.
  • the downstream grinding Stones are completely dispensed with, that the suitability of the stone is precisely manufactured Target brick is achieved in that the cutting to high accuracy takes place so that the required tolerance is achieved without regrinding.
  • a cutting device (4) for the purpose of cutting individual Bricks (1) a cutting device (4) is used, which has a separating wire (5), which during the cutting process with the strand exit speed (v) is moved. It is also advantageous that the cutting device (4) the separating wire (5) by using means known per se in such a way that a Positional accuracy of the separating wire (5) of less than 0.5 millimeters, preferably less than 0.2 millimeters.
  • the burrs can be generated by means of the separating wire in that when cutting the still viscous mass of material through the wire into the area of Cavity is drawn into it. As such, in the prior art, this is considered rather felt disruptive; with subsequent grinding of the stone in known The bricks are therefore deliberately removed from facing bricks.
  • the invention is based on the knowledge that the ridge can be used by helping in applying mortar to the cavities with mortar to be closed as completely as possible, so that there are none over the entire wall height extending hollow chambers, which disadvantageously form a chimney effect can trigger and thus negatively affect the thermal insulation behavior of the wall. Furthermore, the sound insulation effect is not disadvantageous the wall deteriorated.
  • the cutting burrs decrease on the surface of the Stone the effective percentage of holes.
  • the stone is more precisely positioned Installation with a lightweight wall mortar a brick height (H) of 123 Millimeters, 248 millimeters or 498 millimeters has a tolerance of at most ⁇ 2.5 millimeters, preferably ⁇ 1.5 millimeters.
  • H brick height
  • the known face tiles are also adapted to the required wall dimensions, however, their width is reduced to 124, 249 and 499 millimeters with a tolerance of ⁇ 1 millimeter fixed by grinding.
  • the stones according to the invention have preferably a brick height of 123 millimeters, 248 millimeters or 498 Millimeters, the tolerance is preferably ⁇ 1.5 millimeters. So that is processing as a flat brick (with a thin layer of mortar) is also possible, however, post-processing of the stone (grinding) is not necessary.
  • FIG. 1 it can be seen schematically how the method for producing a brick is working.
  • a material mixture 2 is mixed in a mixing container. This can be clay that is prepared (see above) and with sawdust to achieve it a high porosity of the finished stone.
  • the material mixture is supplied to a spray head 3, which drives it out at an exit speed v. Here becomes as uniform as possible over the cross section of the spray head Desired speed distribution.
  • the spray head profiles the material mixture 2 such that the extrudate corresponds to the cross section of the desired stone.
  • a spray cutting device 4 is arranged downstream of the spray head 3. This is shown schematically in the figure as a frame which is vertically movable. He wears a separating wire 5 which is tensioned by the frame. The frame is in Cutting direction s lowered, making a piece of the extruded profile can be separated. The cut is made in such a way that stone blanks 1 with the brick height H.
  • the Cutting device 4 at the moment of cutting with the strand exit speed v moves so that - despite the further movement - a straight cut results.
  • the stone thus produced can be seen in Fig. 2.
  • the strand was cut to length with such accuracy that the stone height H is within a low Tolerance T lies, whereby an order of magnitude of ⁇ 1.5 millimeters is aimed for.
  • the brick 1 can directly as without any finishing (grinding) Planned bricks are installed, whereby a mortar layer of approx. 2 millimeters is provided can be.
  • the stone has - as can be seen in the figure - several (nine in Fig. 2) Cavities 6 on. These not only serve to save weight and material, they also enable improved thermal insulation. By cutting off the stone 1 by means of the separating wire 5 in the cutting direction s have on the surface O of the stone 1 in the region of the opening of the cavity 6 result in cutting burrs 8.
  • the stone according to the invention consciously uses the ridges: the ridge represents one Supported for the mortar that is applied at the masonry. In order to the openings 7 of the cavities 6 can be covered more easily, so that forms a continuous layer of mortar that completely closes the openings 7.
  • the stones 1 are cut to wall dimensions. For the simple installation of the stones they are cut to 123 millimeters, 248 millimeters or 498 millimeters, whereby a tolerance of at most ⁇ 2.5 millimeters, preferably of ⁇ 1.5 millimeters is observed. This enables a positionally accurate installation with a lightweight wall mortar respectively.
