Definitions

  • the invention relates to a sanitary sealing tape for sealing a connection area, in particular a connection area covered by an elastic joint material, with a sealing layer which is adapted to prevent a fluid from passing through the sealing tape, a connection material arranged on the sealing layer which partially or completely covers the sealing layer on at least one side, and a cut protection arranged on the side of the sealing tape facing the connection area.
  • sanitary sealing tapes are used to seal connection areas between a built-in object, such as a bathtub or shower tray, and a wall section or a floor section. Such sanitary sealing tapes can also be used to seal a transition between two adjacent wall sections that are approximately perpendicular to one another or a transition from a wall section to a floor section. Such transitions to be sealed can be found in the kitchen and sanitary area, where a wall or floor surface covered with tiles encounters a wall or floor surface running at an angle thereto or runs counter to a built-in object.
  • the connection areas are usually completely covered by an elastic material in the form of a silicone joint.
  • the sanitary sealing tape Both by means of the joint material and the sanitary sealing tape arranged in the connection area, the ingress of moisture into the wall and / or floor sections of the building behind it should be avoided, preferably prevented.
  • the sanitary sealing tape usually has a sealing layer which is adapted to prevent a fluid from passing through the sealing tape.
  • the sealing tape comprises a connection material which partially or completely covers the sealing layer and which is arranged on at least one side of the sealing tape.
  • the connection material is often designed in the form of a non-woven fabric, which enables a sealing connection to a wall or floor surface using a suitable mortar or adhesive.
  • a cut protection is provided on the side of the sealing tape facing the connection area, which is intended to prevent the sealing layer of the sanitary sealing tape from being damaged in the connection area during assembly or repair work to be carried out subsequently. Damage to the sealing layer could result in a leak and thus the passage of moisture into the wall or floor areas of the building behind it.
  • the joint material becomes detached in the transition area between a built-in object and a wall or floor section due to a corresponding aging process, the joint material must be renewed. This is usually done with the aid of a sharp object, such as a knife, by means of which the joint material is cut or scratched out of the transition area. Without a cut protection then present, the sealing tape could be damaged and its tightness reduced.
  • a thin, flexible metal foil is used to form the cut protection, which has the necessary resistance to a corresponding mechanical influence.
  • Such a sanitary sealing tape is made, for example DE 10 2010 050 752 A1 known.
  • the present invention is therefore based on the object of specifying a sanitary sealing tape for sealing a connection area, the use of which enables simplified assembly even when a cut protection is provided on the sealing tape.
  • the invention solves the problem on which it is based in a sanitary sealing tape for sealing a connection area, in particular a connection area covered by an elastic joint material, with the features of claim 1.
  • the cut protection is a flexible cut protection material made of a flat structure comprising threads or fibers.
  • the approach is pursued here of further increasing its flexibility by providing a cut protection consisting of threads and / or fibers without, however, permitting damage to the sealing layer underneath.
  • the cut protection material which consists of randomly superimposed threads and / or fibers or a plurality of threads having a predetermined alignment to one another, has a minimum thickness that is selected to be so large that if a sharp object with the cut protection of the sanitary sealing tape according to the invention comes into contact, this can not penetrate through the fibers or threads of the sheet to the sealing layer.
  • the flexibility of the cut protection material itself is also advantageously improved.
  • the sanitary sealing tape according to the invention can thus be connected in a simplified manner to a wall or floor section to be brought into contact with the back of the sealing tape even in the case of angled installation situations.
  • the sanitary sealing tape Due to the significantly more flexible design of the cut protection, the sanitary sealing tape has an improved adaptability to angled or uneven surfaces.
  • An installation object to be brought into contact with the front side and thus the side of the sealing tape facing the connection area or a tile layer to be produced on the front side of the sealing tape can then be mounted or placed at a small distance from one another, so that a connection area that is to be jointed is relatively narrow .
  • the cut protection material is connected to the sealing layer or at least partially embedded therein. This achieves a preferably secure connection between the sealing layer and the cut protection and a lateral offset of the cut protection relative to the underlying sealing layer on the sanitary sealing tape according to the invention avoided.

  • a simplified folding or edging of the sealing tape according to the invention is effected, in particular in a connection configured as a corner or edge area, while at the same time ensuring the cut protection for the sealing layer.
  • the textile-like material strip is preferably arranged in the center of the side of the sealing layer facing the connection area.
  • the sealing layer accordingly has laterally protruding layer sections on both sides of the cut protection.
  • connection material covering the sealing layer is arranged running along at least one longitudinal side of the cut protection material, which connection material preferably directly adjoins the cut protection.
  • the connection material is arranged on the side of the sealing layer facing the connection area.
  • the connection material runs directly adjacent along a longitudinal side of the thread and / or fiber having Flat structure trained cut protection. With the help of the connection material arranged on one side, a secure connection between the sanitary sealing tape and the wall and / or floor section of a connection area is possible.
  • the connection material is preferably a flat textile structure which, after it has set, forms a firm connection with the building material used to produce the wall or floor section, such as, for example, mortar or adhesive.

  • the assembly strip preferably extends in the transverse direction of the sealing tape from the cut protection to the adjacent longitudinal side of the sealing tape.
  • the mounting strip which is preferably self-adhesive, runs continuously in the longitudinal direction of the sealing tape.
  • the mounting strip is equipped with a protective layer, such as a protective film, which is to be removed before the sanitary sealing tape according to the invention is mounted on an installation item.
  • a protective layer such as a protective film
  • connection material covering the sealing layer runs along both longitudinal sides of the cut protection material.
  • a connection area is to be created between a wall-to-wall transition or a wall-to-floor transition.
  • Such a wall-wall transition or wall-floor transition is preferred in each case formed by means of corresponding tile layers, which run at an angle of usually 90 ° to each other.
  • a connection of the sealing tape to a mortar or adhesive layer bearing the tiles must accordingly be established.
  • the connection material running along both sides of the cut protection in turn causes the longitudinal sides of the sealing tape to be connected to a mortar or adhesive layer that at least partially covers the longitudinal sides.
  • the sealing tape has a molded part on at least one side of the sealing layer, which is preferably designed to be dimensionally stable.
  • a sealing tape according to the invention with a molded part as a type of reinforcement is preferably used as a connection or cover for an inside or outside corner between two wall areas abutting at an angle.
  • dimensionally stable is to be understood as meaning that a sealing tape equipped with a molded part retains a basic shape, but a slight deformation of the molded part itself is preferably possible.
  • a connection material covering the sealing layer is provided on the side of the sealing tape facing the connection area.
  • the cut protection material is a fabric made of warp threads and weft threads.
  • the design as a fabric offers an advantageous option for producing a textile cut protection.
  • the fabric preferably has a higher resistance to possible action by a sharp object than a flat structure made of threads and / or fibers that run randomly towards one another.
  • the cut resistance is preferably achieved by a certain minimum thickness of the fabric, so that in the event of the object inadvertently sliding along the cut protection, the fabric is not severed. This results in the protection of the sealing layer of the sanitary sealing tape according to the invention lying below the fabric.
  • the fabric preferably has a multiplicity of warp threads which are processed into a fabric via at least one single weft thread. Instead of one weft thread, several weft threads can also be used.
  • the warp threads preferably run in the longitudinal direction of the sealing tape and the weft threads run approximately in the transverse direction of the sealing tape.
  • the warp threads and the at least one weft thread thus run at an angle of approximately 90 ° to one another, as a result of which the cut protection material receives its desired cut resistance.
  • the fabric composed of warp threads and weft threads is preferably set up so that the cut protection can be severed in a simplified manner transversely to the warp threads.
  • the cut protection thus has a preferred severing direction.
  • the sanitary sealing tape according to the invention can thus be simplified and cut to the desired length without great technical effort. This enables the sealing tape to be easily adapted to the given structural requirements on site.
  • the textile material strip preferably has a higher strength transversely to the weft thread than transversely to the warp threads.
  • the fabric-like material strip thus has a higher strength in its longitudinal direction than in its transverse direction.
  • the warp threads are preferably made from aramids and the weft thread from polyethylene with ultra-high molecular weight (UHMW-PE).
  • UHMW-PE ultra-high molecular weight
  • the use of aramids has the advantage that they are heat and fire resistant for a predetermined minimum period.
  • the weft thread made of polyethylene with an ultra-high molecular weight has a tensile strength that is many times higher than that of the warp threads, which means that the cut protection from the fabric only obtains its high cut resistance and, at the same time, advantageous flexibility.
  • connection areas can also be equipped with a sealing tape according to the invention, which are formed from wall or floor sections extending at an angle to one another.
  • the cut protection material has a width of approximately 20 mm with a number of warp threads in the range from 55 to 77. This gives the cut protection material a high level of strength due to the warp threads lying very closely over the entire width of the cut protection.
  • 66 warp threads are preferably used to form the approximately 20 mm wide fabric-like cut protection material.
  • the weft thread has a fineness of 880 dtex and / or the weft density on the cut protection material is in the range of approximately 14.9 per inch.
  • the weft thread preferably has a relatively high mass per length compared to conventional textile threads. This ensures the strength of the weft thread itself, and in conjunction with the selected weft density, the high strength of the entire fabric is generated in its longitudinal direction.
  • the sealing layer and / or the assembly strip is preferably formed from a material having elastic properties, in particular a flexible plastic or a rubber material. With the aid of the plastic or the rubber material, a sealing layer can be formed with which the passage of the fluid through the sanitary sealing tape according to the invention is avoided.
  • a rubber layer is preferably produced from the rubber material used, which acts as a sealing layer within the sealing tape.
  • the mounting strip is preferably formed from a butyl rubber with self-adhesive properties, which enables a connection to a built-in object to be mounted.
