Definitions

  • Liquid-tight floor or wall coverings of the above Type and a test method of the above also mentioned kind are known from the relevant practice.
  • the electric There is usually a conductive adhesive layer from an epoxy resin, the electrically conductive pigments, preferably carbon or metal powder are.
  • a floor or wall covering with the structure explained above is in principle due to the electrical Procedure for its tightness can be checked, but delivers the check in practice relatively often results of errors.
  • error results exist in particular in the fact that imperfections in the joint filling, that is, unfilled Cavities that are not recognizable from above the test cannot be determined.
  • the electrical Conductivity of the adhesive layer is limited and cannot be increased arbitrarily. So that the adhesive layer their primary task, namely the permanent connection between the ceramic plates on the one hand and on the other hand can support the supporting subsurface, the pigment content may only reach a limited size. If this size is exceeded, the adhesive bridge layer loses their ability to the plates and the underground to connect permanently and sufficiently firmly.
  • the adhesive layer can provide this necessary accuracy and care is not always required.
  • the electrical properties of the adhesive layer over long periods of time, at least several Months can still change noticeably, so that in later retakes with different conditions, which are not exactly known, are to be counted when she immediately after making the bob- or wall covering.
  • the electrical properties the adhesive layer will not only be influenced by time, or additionally due to the moisture content of the adhesive layer, the lack of waterproofing of the supporting surface to the side opposite the floor or wall covering can fluctuate in relatively wide ranges.
  • a floor or wall covering of the type mentioned at the beginning which is characterized in that under or over or in the adhesive layer in direct contact with this additionally a network layer from an electrical conductive material is arranged with at least one arranged outside or above the covering Contact point is electrically connected or connectable.
  • the adhesive layer as a whole that is including the network situation, defined and over time maintains constant electrical properties. additionally the network situation also improves mechanical bonding of the adhesive layer in itself, whereby not only the electrical properties but also the mechanical properties of the adhesive layer be improved.
  • the specific electrical Network layer resistance is less than the specific one electrical resistance of the adhesive layer yourself.
  • the adhesive layer is applied in two sub-layers, whereby the mesh layer is inserted between the two sub-layers is.
  • the mesh layer is preferred due to a coarse-mesh fabric or braid made of synthetic fibers.
  • the required electrical conductivity is determined by selection guaranteed according to electrically conductive synthetic fibers.
  • Synthetic fibers ensured that the mesh layer is insensitive against physical and chemical influences.
  • such a network position is mechanically less sensitive than, for example, fabrics or braids in which metallic wires woven or braided are.
  • To facilitate handling and manufacturing the fabric or braid is expediently in the form of rolled goods provided and then in the form of parallel tracks designed.
  • the lanes designed should overlap in their edge areas in order to required electrical contact between the ensure parallel adjacent tracks. If necessary can also be a mutual fixation the webs of the network layer take place, this fixation also be carried out additionally or alternatively can be that there is a fixation relative to the surface.
  • the reference number 3 denotes a grown soil, on which as load-bearing A concrete slab 2 is applied underground.
  • the top of the concrete slab can do what's in the drawing is exaggerated, have irregularities.
  • an acid screed or acid kit layer 14 applied to it serves the surface chemically and physically for the prepare the floor covering 1 to be applied.
  • the Top of layer 14 is also used to achieve the necessary flatness as smooth as possible.
  • the layer 14 of acid screed is connected at the top or acid putty to an adhesive bridge layer 12, which are made of an electrically conductive material, preferably Made of an epoxy resin with electrically mixed conductive pigments, e.g. Carbon or metal powder, consists.
  • an adhesive bridge layer 12 which are made of an electrically conductive material, preferably Made of an epoxy resin with electrically mixed conductive pigments, e.g. Carbon or metal powder, consists.
  • a net layer 13 which is shown in the Embodiment completely within the adhesive layer 12 is located.
  • the network layer 14 consists of a electrically conductive material, the specific electrical resistance of the network layer 13 preferably is smaller than the specific electrical resistance the adhesive layer 12.
  • the net layer 13 is preferably from a fabric or braid from electrical conductive synthetic fibers to protect them against physical and to make chemical influences insensitive.
  • the Net layer 13 stands, which is not specifically shown in the drawing is via an electrically conductive connection with at least one above or outside the flooring 1 arranged contact element in connection.
  • Connection of the net layer 13 to the contact element can For example, tapes are used that are made from the same material as the net layer 13, and the are laid so that they contact the network layer 13 on the one hand and on the other hand with the mentioned contact element are electrically connected or connectable.
  • a layer of ceramic continues to close at the top Plates 10, which in turn are electrically non-conductive are. Between the individual neighboring plates 10, which are laid at a defined distance from each other are, there is a joint filling 11, which is shown in the Embodiment also electrically non-conductive is.
  • the adhesive bridge layer 12 is already rising partly in the joints between the neighboring ones Plates 10 on. It is over most of its height Groove between the adjacent panels 10 but through the Joint filling 11 finally introduced from above.
  • the floor covering 1 In the manufacture or later use of the Floor covering 1 can cause unwanted hairline cracks or gaps in the joint fillings 11 or in the Plates 10 arise, the lack of quality of the Floor covering 1 because they are durability and Leak tightness can impair in the long run. to Detection of such cracks and crevices becomes an in itself known test method used by means of electrical High voltage is the dielectric strength of the floor covering 1 determined.
  • the device also known per se has a electric pulse generator, the high voltage pulses generated.
  • An electrical pole of the device becomes Carrying out the measurement with the network layer 13 via the mentioned contact element connected; the other pole of the Device is attached to a movable contact element that for example broom-shaped with metallic contact bristles is connected. This contact brush is moved systematically over the entire floor covering 1, with a high voltage flashover for each fault occurs, which is indicated by the device. On in this way, imperfections in the floor covering 1 can be determined, so that a targeted improvement is then made at these points can be done.
  • the floor covering 1, as described above, not only enables an exact check on its Tightness, but also offers or alternatively still the possibility to derive static charges, for example in work rooms where static charges must be avoided.
