Description

Die Erfindung betrifft einen Schnittschutzstreifen, insbesondere einen Schnittschutzstreifen, der als mechanischer Schutz im Bereich von Sanitärfugen verwendbar ist. Ausserdem betrifft die Erfindung die Verwendung eines solchen Schnittschutzstreifens.The invention relates to a cut protection strip, in particular a cut protection strip which can be used as a mechanical protection in the field of sanitary joints. In addition, the invention relates to the use of such a cut protection strip.

Es gibt in und an Gebäuden Fugen, die mit einer meist elastischen Fugenmasse versehen sind. Solche Fugen werden zum Beispiel als Dehnungsfugen in Bereichen vorgesehen, bei denen unterschiedliche Materialien aufeinander treffen. Dehnungsfugen werden aber auch z.B. im Bodenbereich vorgesehen, um schwimmend verlegte Bodenbeläge zu unterteilen. Im Sanitärbereich ergeben sich solche Fugen unter anderem im Anschlussbereich zwischen Sanitärinstallationen (z.B. einer Badewanne) und einem daran anschliessenden Wandbelag (z.B. in Form von Fliesen). Weiterhin ergeben sich solche Fugen auch im Übergangsbereich zwischen einem Bodenbelag und einem Wandbelag und auch in Raumecken.There are joints in and on buildings, which are provided with a mostly elastic grout. Such joints are provided, for example, as expansion joints in areas where different materials meet. However, expansion joints are also used e.g. provided in the floor area to subdivide floating floor coverings. In the sanitary sector, such joints result, inter alia, in the connection area between sanitary installations (for example a bathtub) and a subsequent wall covering (for example in the form of tiles). Furthermore, such joints also result in the transition region between a floor covering and a wall covering and in room corners.

Falls sich Setzungserscheinungen der Fugenmasse zeigen, oder falls die Fugenmasse unansehnlich geworden sein sollte, so wird diese häufig mittels eines Teppichmessers aus der Fuge herausgelöst, bevor dann neue Fugenmasse eingebracht wird. Dabei kann es zu einer Zerstörung von darunter befindlichen Schichten kommen. So kann z.B. ein Dichtband zertrennt werden oder es kann eine Flüssigabdichtung oder eine Spezialabdichtung durchschnitten werden. Dadurch kann Feuchtigkeit z.B. in eine Wand eindringen.If subsidence of the grout show, or if the grout should have become unsightly, it is often removed by means of a carpet knife from the joint, before then new grout is introduced. This can lead to the destruction of underlying layers. For example, a sealing tape can be cut or a liquid seal or a special seal can be cut through. As a result, moisture can penetrate eg into a wall.

Es stellt sich die Aufgabe einen Schnittschutzstreifen bereitzustellen, der sich gut handhaben und vor allem gut aufwickeln und somit auch transportieren lässt. Insbesondere soll dabei jedoch die Schnittschutzfunktion des Schnittschutzstreifens nicht beeinträchtigt werden.It raises the task of providing a cut protection strip, which is easy to handle and above all well wound and thus can be transported. In particular, however, the cut protection function of the cut protection strip should not be affected.

Vorzugsweise kommt der Schnittschutzstreifen dort zum Einsatz, wo sich zwischen Fliesen, Steinzeug, Platten oder dergleichen eine Fuge ergibt.Preferably, the cut protection strip is used where there is a gap between tiles, stoneware, slabs or the like.

Der Schnittschutzstreifen soll vor allem für den Einbau im Bereich von Sanitärräumen, Küchen und Schwimmbädern geeignet sein. Insbesondere soll sich der Schnittschutzstreifen im Bereich sanitärer Anlagen, Küchen, Schwimmbäder, Saunen und ähnlicher Bereiche mit Dichtbändern und Anschlussbändern kombinieren lassen. Ein Schnittschutzstreifen gemäß dem Oberbegriff des Anspruchs 1 ist aus AT 510127 A1 bekannt.The cut protection strip should be suitable above all for the installation in the range of sanitary rooms, kitchens and swimming pools. In particular, the cut protection strips in the field of sanitary facilities, kitchens, swimming pools, saunas and similar areas should be combined with sealing tapes and connection tapes. A cut protection strip according to the preamble of claim 1 is made AT 510127 A1 known.

Diese Aufgabe wird durch einen Schnittschutzstreifen gemäß Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen enthalten. Eine entsprechende Verwendung eines Schnittschutzstreifens ist dem Anspruch 11 zu entnehmen.This object is achieved by a cut protection strip according to claim 1. Advantageous embodiments are contained in the subclaims. A corresponding use of a cut protection strip can be found in claim 11.

Der erfindungsgemäße Schnittschutzstreifen zeichnet sich dadurch aus, dass er eine Streifenlänge und eine dazu senkrecht stehende Streifenbreite aufweist, wobei die Streifenlänge mit der dazu senkrecht stehenden Streifenbreite eine Ebene definiert. Der Schnittschutzstreifen umfasst:

  • einen ersten Längsstreifen,
  • einen zweiten Längsstreifen,
  • eine Längssicke oder -rille, die sich parallel zu der Streifenlänge erstreckt und die zwischen dem ersten Längsstreifen und dem zweiten Längsstreifen angeordnet ist,
wobei der Schnittschutzstreifen aus der flachen Ursprungsform in eine Montageform überführbar ist, indem mindestens einer der Längsstreifen des Schnittschutzstreifens entlang der Längssicke oder -rille aus der Ebene heraus in eine abgewinkelte Position überführt wird.The cut protection strip according to the invention is characterized in that it has a strip length and a strip width perpendicular thereto, the strip length defining a plane perpendicular to the strip width. The cut protection strip comprises:
  • a first longitudinal strip,
  • a second longitudinal strip,
  • a longitudinal bead or groove which extends parallel to the strip length and which is arranged between the first longitudinal strip and the second longitudinal strip,
wherein the cut protection strip from the flat original shape can be converted into an assembly form by transferring at least one of the longitudinal strips of the cut protection strip out of the plane into an angled position along the longitudinal bead or groove.

Der erfindungsgemäße Schnittschutzstreifen einer bevorzugten Ausführungsform zeichnet sich dadurch aus, dass er eine Streifenlänge und eine dazu senkrecht stehende Streifenbreite hat, wobei der Schnittschutzstreifen eine flächige Metall-Gitterstruktur umfasst. Diese Metall-Gitterstruktur liegt in einer Ebene, welche durch die Streifenlänge und die Streifenbreite definiert ist. Die Metall-Gitterstruktur erstreckt sich entlang der Streifenlänge und sie weist eine Längssicke oder -rille auf. Die Längssicke oder -rille erstreckt sich parallel zu der Streifenlänge und sie teilt die Metall-Gitterstruktur in einen ersten Längsstreifen oberhalb der Längssicke oder -rille und einen zweiten Längsstreifen unterhalb der Längssicke oder -rille. Die Metall-Gitterstruktur ist so ausgelegt, dass mindestens einer der Längsstreifen entlang der Längssicke oder -rille aus der Ebene heraus in eine abgewinkelte Position biegbar ist.The cut protection strip according to the invention of a preferred embodiment is characterized in that it has a strip length and a strip width perpendicular thereto, the cut protection strip comprising a flat metal grid structure. This metal lattice structure lies in a plane which is defined by the strip length and the strip width. The metal grid structure extends along the strip length and has a longitudinal bead or groove. The longitudinal bead or groove extends parallel to the strip length and divides the metal grid structure into a first longitudinal strip above the longitudinal bead or groove and a second longitudinal strip below the longitudinal bead or groove. The metal grid structure is designed such that at least one of the longitudinal strips is bendable out of the plane into an angled position along the longitudinal bead or groove.

Definitionsgemäß soll es sich bei der Metall-Gitterstruktur um ein (festes) Netz, Gewebe, Geflecht, Lochgitter, oder Gelege handeln, das in der Ebene flexibel ist.By definition, the metal lattice structure should be a (solid) mesh, woven, braided, perforated, or scrim flexible in the plane.

Vorzugsweise ist die Metall-Gitterstruktur bei allen Ausführungsformen so flexibel ausgelegt, dass ein Längenabschnitt der Metall-Gitterstruktur und/oder des Schnittschutzstreifens aufrollbar ist.In all embodiments, the metal grid structure is preferably configured so flexibly that a longitudinal section of the metal grid structure and / or the cut protection strip can be rolled up.

Des Weiteren soll die Bezeichnung "Streifen" darauf hinweisen, dass sich die Geometrie in eine Richtung, der sogenannten "Streifenlängsrichtung", sehr weit erstreckt, während die senkrecht hierzu gemessene Breite und Dicke des Streifens sehr viel geringer sind. Typischerweise hat der Schnittschutzstreifen quer zur Bandrichtung einen im Wesentlichen länglichen, rechteckigen Querschnitt mit einer Breite, welche (ein Mehrfaches) größer als die Dicke des Bandes ist.Furthermore, the term "strip" is intended to indicate that the geometry in one direction, the so-called "strip longitudinal direction", extends very far, while the perpendicular measured thereto width and thickness of the strip are much lower. Typically, the cut protection strip has a substantially oblong rectangular cross-section transverse to the belt direction, having a width which is (several times) greater than the thickness of the belt.

Die Breite des Schnittschutzstreifens kann bei allen Ausführungsformen beispielsweise zwischen ca. 2 cm und 20 cm betragen.The width of the cut protection strip may be, for example, between about 2 cm and 20 cm in all embodiments.

Seine Dicke kann bei allen Ausführungsformen typischerweise zwischen ca. 0,5 mm und 5 mm liegen.Its thickness may typically be between about 0.5 mm and 5 mm in all embodiments.

Die flächige Metall-Gitterstruktur, falls vorhanden, umfasst bei allen Ausführungsformen Löcher, Ausnehmungen oder Maschen, die vorzugsweise kleiner sind als 5 mm.The planar metal grid structure, if present, in all embodiments includes holes, recesses or meshes, which are preferably smaller than 5 mm.

Der Schnittschutzstreifen kann bei allen Ausführungsformen zweilagig oder mehrlagig sein.The cut protection strip may be two-ply or multi-ply in all embodiments.

Der beschriebene Schnittschutzstreifen mit der flächigen Metall-Gitterstruktur hat den Vorteil, dass er sich für eine Lagerung und für den Transport problemlos auf einer Rolle aufwickeln lässt, da die Metall-Gitterstruktur für eine Flexibilität des Schnittschutzstreifens sorgt. Aufgrund der Gitterstruktur lässt sich der Schnittschutzstreifen z.B. auf eine Rolle aufrollen und sie lässt sich beim Installieren um eine Rundung herum führen (falls sie flächig verlegt wird). Daher kann ein solcher Schnittschutzstreifen auch um Kanten und Radien von (Sanitär-)Gegenständen oder Einrichtungen herum verlegt werden. Falls der Schnittschutzstreifen in der abgewinkelten Form um einen Radius herum verlegt werden soll, so können (z.B. mit einer Metallschere) in einem der Längsstreifen keilförmige Ausschnitte vorgesehen werden.The described cut protection strip with the flat metal lattice structure has the advantage that it can easily be wound up on a roll for storage and for transport, since the metal lattice structure ensures flexibility of the cut protection strip. Due to the lattice structure, the cut protection strip can be made e.g. Roll up on a roll and it can be guided around a rounding when installing (if it is laid flat). Therefore, such a cut protection strip can also be laid around edges and radii of (sanitary) objects or facilities. If the cut protection strip is to be laid in the angled shape around a radius, wedge shaped cutouts may be provided in one of the longitudinal strips (e.g., with metal scissors).

Mindestens ein Längsrand des Schnittschutzstreifens kann bei allen Ausführungsformen optional ein anderes Material und/oder eine andere Struktur aufweisen wie die Längsstreifen. Ein solcher Schnittschutzstreifen lässt sich besser handhaben, da er beim Einbau z.B. mit den Fingern an dem Längsrand gehalten werden kann.At least one longitudinal edge of the cut protection strip may optionally have a different material and / or a different structure than the longitudinal strips in all embodiments. Such a cut protection strip can be handled better, since it can be used during installation e.g. can be held with the fingers on the longitudinal edge.

Mindestens ein Längsrand des Schnittschutzstreifens kann bei allen Ausführungsformen optional einen Vliesstreifen umfassen, um das Einbetten des Schnittschutzstreifens z.B. in eine Verbundabdichtung zu erleichtern.At least one longitudinal edge of the cut protection strip may optionally comprise a nonwoven strip in all embodiments to facilitate embedding of the cut protection strip e.g. to facilitate in a composite seal.

Gemäß einer Ausführungsform ist die Längssicke mittig in der Metall-Gitterstruktur angeordnet. Die Längssicke oder -rille kann bei allen Ausführungsformen aber auch aussermittig angeordnet sein, wobei sich die Längssicke oder -rille jedoch stets parallel zu der Längsrichtung des Schnittschutzstreifens erstreckt.According to one embodiment, the longitudinal bead is arranged centrally in the metal grid structure. The longitudinal bead or groove may also be arranged eccentrically in all embodiments, wherein the However, longitudinal bead or groove always extends parallel to the longitudinal direction of the cut protection strip.

Mindestens eine Fläche des Schnittschutzstreifens kann bei allen Ausführungsformen optional mit einem Klebstoff versehen werden, um den Schnittschutzstreifen an einem Gegenstand (Badewanne, Duschrinne, Wand, Boden etc.) oder einem weiteren Produktteil (Dichtband, Dichtungsfolie, Wannenband, etc.) befestigen zu können.At least one surface of the cut protection strip can optionally be provided with an adhesive in all embodiments in order to secure the cut protection strip to an object (bathtub, shower channel, wall, floor, etc.) or another product part (sealing tape, sealing film, tub strap, etc.) ,

Vorzugsweise kann bei allen Ausführungsformen ein mehrlagig aufgebauter Butyl-Klebstoff zum Einsatz kommen, der mindestens eine Folie und mindestens eine Butylschicht umfasst.Preferably, in all embodiments, a multi-layered butyl adhesive may be used which comprises at least one film and at least one butyl layer.

Die verschiedenen Ausführungsformen der Erfindung, die aus mehreren Teilen bzw. Elementen zusammengefügt sind, können auch in Einzelteilen geliefert und vor Ort miteinander verbunden werden.

Im Folgenden werden Orts- und Richtungsangaben verwendet, um die Erfindung besser beschreiben zu können. Diese Angaben beziehen sich auf die jeweilige Einbausituation und sollen daher nicht als Einschränkung verstanden werden. Um die Orts- und Richtungsangaben besser eingrenzen zu können, wird teilweise auch ein Bezug zur Wand (auch Vertikalfläche genannt) hergestellt, in dem z.B. von einem wandnahen Element, einer wandzugewandten, wandabgewandten Fläche oder einer wandparallelen Montage die Rede ist.In the following location and direction are used to describe the invention better. These details refer to the respective installation situation and should therefore not be interpreted as a restriction. In order to better define the location and direction information, a reference to the wall (also called vertical surface) is partially made, in which e.g. from a wall-near element, a wall facing, wall facing away from the surface or a wall-parallel assembly is the speech.

Die Erfindung wird im Folgenden anhand einiger Ausführungsbeispiele beschrieben.The invention will be described below with reference to some embodiments.

Es geht hier um Schnittschutzstreifen 10, die in einer flachen Ursprungsform eine Streifenlänge Lx (parallel zur x-Achse) und eine dazu senkrecht stehende Streifenbreite bs (parallel zur y-Achse) aufweisen. In den Figuren 1A, 1B, 2A, 2B, 3A, 4, 5A und 5B sind verschiedene Ausführungsformen jeweils in der flachen Ursprungsform gezeigt. In den Figuren 3B und 7 sind Schnittschutzstreifen 10 in der abgewinkelten Montageform gezeigt.This is cut protection strips 10, which have a strip length Lx (parallel to the x-axis) and a strip width b s perpendicular to it (parallel to the y-axis) in a flat original shape. In the FIGS. 1A, 1B . 2A, 2B . 3A . 4 . 5A and 5B For example, various embodiments are shown in the flat original form. In the FIGS. 3B and 7 Cut protection strips 10 are shown in the angled mounting form.

Die Streifenlänge Lx definiert mit der dazu senkrecht stehenden Streifenbreite bs eine Ebene E. Bei den Figuren 1A, 2A, 4 und 5A liegt diese Ebene E in der Zeichnungsebene.The strip length Lx defined with the perpendicular stripe width b s a plane E. In the Figures 1A . 2A . 4 and 5A this plane E lies in the plane of the drawing.

Der Schnittschutzstreifen 10 umfasst bei allen Ausführungsformen einen ersten Längsstreifen 16.1 und einen zweiten Längsstreifen 16.2. Weiterhin umfasst der Schnittschutzstreifen 10 bei allen Ausführungsformen eine Längssicke oder -rille 14, die sich parallel zu der Streifenlänge Lx erstreckt und die zwischen dem ersten Längsstreifen 16.1 und dem zweiten Längsstreifen 16.2 angeordnet ist.The cut protection strip 10 comprises in all embodiments a first longitudinal strip 16.1 and a second longitudinal strip 16.2. Furthermore, the cut protection strip 10 in all embodiments comprises a longitudinal bead or groove 14 which extends parallel to the strip length Lx and which is arranged between the first longitudinal strip 16.1 and the second longitudinal strip 16.2.

Diese Längssicke oder -rille 14 definiert bei allen Ausführungsformen einen Biegebereich oder die Längssicke oder -rille 14 ermöglicht ein scharnierartiges Klappen eines ersten Längsstreifens in Bezug zu einem zweiten Längsstreifen. Die Verwendung der Worte "Sicke" und "Rille" ist daher als Mittel zum Erzielen dieser Biegbarkeit oder Klappbarkeit zu verstehen. Die Längssicke oder -rille 14 muss im Querschnitt betrachtet nicht zwingend eine Kavität darstellen.This longitudinal bead or groove 14 defines a bending region in all embodiments, or the longitudinal bead or groove 14 allows hingedly folding a first longitudinal strip with respect to a second longitudinal strip. The use of the words "bead" and "groove" is therefore to be understood as a means to achieve this flexibility or foldability. The longitudinal bead or groove 14 does not necessarily have to represent a cavity when viewed in cross-section.

Der Schnittschutzstreifen 10 ist bei allen Ausführungsformen so ausgelegt, dass er aus der flachen Ursprungsform in eine abgewinkelte Montageform überführbar ist. Das geschieht, indem mindestens einer der Längsstreifen 16.1, 16.2 des Schnittschutzstreifens 10 entlang der Längssicke oder -rille 14 aus der Ebene E heraus in eine abgewinkelte Position gebogen oder geklappt wird.The cut protection strip 10 is designed in all embodiments so that it can be converted from the flat original shape into an angled mounting form. This is done by bending or folding at least one of the longitudinal strips 16.1, 16.2 of the cut protection strip 10 along the longitudinal bead or groove 14 out of the plane E into an angled position.

In den Figuren 1A und 1B ist eine erste Ausführungsform eines Schnittschutzstreifens 10 gezeigt. Dieser Schnittschutzstreifen 10 besteht aus dem ersten Längsstreifen 16.1, dem zweiten Längsstreifen 16.2 und der Längssicke oder -rille 14. Die Streifenbreite bs entspricht hier der Gesamtbreite b (siehe auch Fig. 2A). Im Schnitt entlang der Schnittlinie I-I kann man erkennen, dass bei allen Ausführungsformen z.B. eine Längskavität als Längssicke oder -rille 14 dienen kann. Das Material der Längssicke oder -rille 14 ist hier identisch mit dem Material der Längsstreifen 16.1, 16.2. Es handelt sich also um eine einstückige Ausführungsform.In the Figures 1A and 1B a first embodiment of a cut protection strip 10 is shown. This cut protection strip 10 consists of the first longitudinal strip 16.1, the second longitudinal strip 16.2 and the longitudinal bead or groove 14. The strip width b s here corresponds to the total width b (see also FIG Fig. 2A ). It can be seen in section along the section line II that in all embodiments, for example, a longitudinal cavity can serve as a longitudinal bead or groove 14. The material of the longitudinal bead or groove 14 is here identical to the material of the longitudinal strips 16.1, 16.2. It is therefore an integral embodiment.

Da mindestens die Längsstreifen 16.1, 16.2 vorzugsweise aus einem Gittermaterial gefertigt sind, ist dieses Gittermaterial, respektive der Bereich, der das Gittermaterial umfasst, mit dem Bezugszeichen 11 bezeichnet.Since at least the longitudinal strips 16.1, 16.2 are preferably made of a grid material, this grid material, or the area comprising the grid material, is designated by the reference numeral 11.

In den Figuren 2A und 2B ist eine zweite Ausführungsform eines Schnittschutzstreifens 10 gezeigt. Dieser Schnittschutzstreifen 10 umfasst einen ersten Längsstreifen 16.1, einen zweiten Längsstreifen 16.2, eine Längssicke oder -rille 14, sowie einen oberen Randstreifen 12 und einen unteren Randstreifen 13. Die Streifenbreite bs der Längsstreifen 16.1, 16.2 ist daher kleiner als die Gesamtbreite b. Im Schnitt entlang der Schnittlinie I-I kann man erkennen, dass auch hier eine Längskavität als Längssicke oder -rille 14 dient. Ausserdem ist in Fig. 2B angedeutet, dass die Randstreifen 12, 13 ein anderes Material umfassen als die Längsstreifen 16.1, 16.2.In the FIGS. 2A and 2B a second embodiment of a cut protection strip 10 is shown. This cut protection strip 10 comprises a first longitudinal strip 16.1, a second longitudinal strip 16.2, a longitudinal bead or groove 14, and an upper edge strip 12 and a lower edge strip 13. The strip width b s of the longitudinal strips 16.1, 16.2 is therefore smaller than the total width b. In the section along the section line II you can recognize that here too a longitudinal cavity serves as a longitudinal bead or groove 14. Moreover, in Fig. 2B indicated that the edge strips 12, 13 comprise a different material than the longitudinal strips 16.1, 16.2.

Die Längsstreifen 16.1, 16.2 können beispielsweise ein Gittermaterial 11 umfassen, wohingegen die Randstreifen 12, 13 zum Beispiel ein Kunststoffmaterial und/oder eine Vliesmaterial umfassen.The longitudinal strips 16.1, 16.2 may, for example, comprise a grid material 11, whereas the edge strips 12, 13 comprise, for example, a plastic material and / or a nonwoven material.

In Fig. 3A ist ein Längenabschnitt eines weiteren Schnittschutzstreifens 10 mit der Länge Lx gezeigt. Der Schnittschutzstreifen 10 der Fig. 3A kann z.B. so aufgebaut sein wie der Schnittschutzstreifen 10 der Fig. 1A. In Fig. 3B ist ein kürzerer Längenabschnitt des Schnittschutzstreifens 10 der Fig. 3A in einer Montageform gezeigt. Hier wurde der Längsstreifen 16.2 entlang der Längssicke oder -rille 14 nach vorne gebogen. Der Längsstreifen 16.1 liegt weiterhin in der bereits erwähnten Ebene E.In Fig. 3A a length section of another cut protection strip 10 of length Lx is shown. The cut protection strip 10 of Fig. 3A For example, may be constructed as the cut protection strip 10 of Fig. 1A , In Fig. 3B is a shorter length portion of the cut protection strip 10 of Fig. 3A shown in an assembly form. Here, the longitudinal strip 16.2 has been bent forward along the longitudinal bead or groove 14. The longitudinal strip 16.1 continues to lie in the already mentioned plane E.

In Fig. 4A ist ein Längenabschnitt eines weiteren Schnittschutzstreifens 10 gezeigt. Dieser Schnittschutzstreifen 10 ist wiederum einstückig aufgebaut, wobei die Längssicke oder -rille 14 mit Unterbrechungen ausgeführt ist. D.h. die Längssicke oder -rille 14 ist in Längsrichtung betrachtet nicht durchgehend ausgebildet. Trotzdem erfüllt auch eine solche Längssicke oder -rille 14 mit Unterbrechungen den Zweck. Sie definiert eine Biegekante, die sich parallel zur x-Achse erstreckt.In Fig. 4A a longitudinal section of a further cut protection strip 10 is shown. This cut protection strip 10 is in turn constructed in one piece, wherein the longitudinal bead or groove 14 is executed with interruptions. That is to say that the longitudinal bead or groove 14 is not continuous in the longitudinal direction. Nevertheless, such a longitudinal bead or groove 14 intermittently fulfills the purpose. It defines a bending edge that extends parallel to the x-axis.

Die Längssicke oder -rille 14 kann bei allen Ausführungsformen auch z.B. durch längliche Schlitze gebildet werden, die entlang einer Linie parallel zur x-Achse verlaufen.The longitudinal bead or groove 14 may in all embodiments also be e.g. are formed by elongated slots that run along a line parallel to the x-axis.

In Fig. 4B zeigt eine schematische Ansicht eines solchen einstückigen Schnittschutzstreifens 10, der komplett aus einem schnittfesten Materialstreifen besteht und der eine Längssicke oder -rille 14 aufweist, die durch Längsschlitze definiert ist.In Fig. 4B shows a schematic view of such a one-piece cut protection strip 10, which consists entirely of a cut-resistant strip of material and having a longitudinal bead or groove 14 which is defined by longitudinal slots.

In Fig. 5A ist ein Längenabschnitt eines weiteren Schnittschutzstreifens 10 gezeigt. Dieser Schnittschutzstreifen 10 ist mehrstückig aufgebaut. Dieser Schnittschutzstreifen 10 umfasst zwei separate Längsstreifen 16.1, 16.2, die im Bereich der Längssicke oder -rille 14 miteinander verbunden sind. Als Verbindung dient hier, wie man in Fig. 5B erkennen kann, ein flexibler Materialstreifen 15. Dieser flexible Materialstreifen kann z.B. mit den beiden Längsstreifen 16.1, 16.2 verklebt, verschweisst oder anderweitig verbunden sein. Aufgrund der Flexibilität des Materialstreifens 15, kann auch die Ausführungsform der Figuren 5A, 5B aus einer flachen Ursprungsform und die Montageform überführt werden. Im Bereich der Längssicke oder -rille 14 können die beiden Längsstreifen 16.1, 16.2 Stoss an Stoss liegen oder es kann sich dort ein kleiner Abstand zwischen diesen beiden Längsstreifen 16.1, 16.2 ergeben.In Fig. 5A a longitudinal section of a further cut protection strip 10 is shown. This cut protection strip 10 is constructed in several pieces. This cut protection strip 10 comprises two separate longitudinal strips 16.1, 16.2, which are connected to one another in the region of the longitudinal bead or groove 14. The connection here is how to get in Fig. 5B can recognize a flexible strip of material 15. This flexible strip of material can be glued, welded or otherwise connected, for example, with the two longitudinal strips 16.1, 16.2. Due to the flexibility of the material strip 15, the embodiment of the FIGS. 5A, 5B be converted from a flat original shape and the mounting form. In the region of the longitudinal bead or groove 14, the two longitudinal strips 16.1, 16.2 may be buttocks or there may be a small distance between these two longitudinal strips 16.1, 16.2.

In den Figuren 6A bis 6E sind unterschiedliche Gitterstrukturen 11 gezeigt. Diese Gitterstrukturen 11 sind sowohl für einstückige als auch für mehrstückige Ausführungsformen der Erfindung geeignet. Vorzugsweise handelt es sich um Metall- oder Kunststoff-Gitterstrukturen 11.In the FIGS. 6A to 6E different lattice structures 11 are shown. These grid structures 11 are suitable for both one-piece and multi-piece embodiments of the invention. Preferably, these are metal or plastic grid structures 11.

Fig. 7 zeigt eine mögliche Einbausituation in stark schematisierter Form. Es ist ein Gebäudeeck zu erkennen, bei dem z.B. zwei Wände aneinanderstossen. Entlang des Ecks, das hier senkrecht auf der Zeichnungsebene steht, wurde ein Dichtband 17 verlegt. Dieses Dichtband 17 ist durch dicke schwarze Linien dargestellt und weist hier zwei Schenkel auf, die im Eck ineinander übergehen. Ein Schnittschutzstreifen 10 ist vor dem Dichtband 17 montiert. Es sind zwei Fliesen 20 gezeigt, die mittels eines Fliesenklebers 18 angebracht wurden. Zwischen den beiden Fliesen 20 ergibt sich im Eck eine Fuge, die hier mit einem grau dargestellten Fugenmaterial 19 versehen ist. Fig. 7 shows a possible installation situation in a highly schematic form. It can be seen a building corner, in which, for example, two walls collide. Along the corner, which stands here perpendicular to the plane of the drawing, a sealing tape 17 has been laid. This sealing tape 17 is represented by thick black lines and here has two legs, which merge into each other in the corner. A cut protection strip 10 is mounted in front of the sealing strip 17. Two tiles 20 are shown, which were attached by means of a tile adhesive 18. Between the two tiles 20 results in the corner of a joint, which is provided here with a gray joint material 19 shown.

Anhand dieser Fig. 7 kann man erkennen, wie ein Schnittschutzstreifen 10 der Erfindung in der abgewinkelten Form im Eckbereich montiert wird (die Längsachse x steht hier senkrecht auf der Zeichnungsebene). Es ist auch zu erkennen, dass die Längssicke oder -rille 14 nicht mit einem Teppichmesser erreicht werden kann, wenn versucht wird die Fugenmassen 19 zu entfernen. Ein solches Teppichmesser wird eher den hier aufwärtsweisenden Längsstreifen 16.1 des Schnittschutzstreifens 10 erreichen als die weiter unten liegende Längssicke oder -rille 14.Based on this Fig. 7 It can be seen how a cut protection strip 10 of the invention in the angled form is mounted in the corner region (the longitudinal axis x is perpendicular to the plane of the drawing). It will also be appreciated that the longitudinal bead or groove 14 can not be achieved with a carpet knife when attempting to remove the grout 19. On Such a carpet knife will rather reach the upwardly facing longitudinal strips 16.1 of the cut protection strip 10 than the lower strip or groove 14 located further down.

Daraus ergibt sich, dass die Längssicke oder -rille 14 nicht zwingend aus einem schnittfesten Material (z.B. aus eine Gitterstruktur) gefertigt sein muss, wie dies bei den Ausführungsformen der Figuren 1A, 1B, 2A, 2B, 3A, 3B und 4 der Fall ist. Im Bereich der Längssicke oder -rille 14 kann durchaus auch ein Material zum Einsatz kommen, das nicht schnittfest ist, wie anhand der Ausführungsform der Fig. 5A, 5B gezeigt.It follows that the longitudinal bead or groove 14 is not necessarily made of a cut-resistant material (eg, a grid structure) must be made, as in the embodiments of the FIGS. 1A, 1B . 2A, 2B . 3A, 3B and 4 the case is. In the region of the longitudinal bead or groove 14 may well be a material used, which is not cut-resistant, as based on the embodiment of Fig. 5A, 5B shown.

Fig. 8 zeigt eine weitere mögliche Einbausituation in stark schematisierter Form. Es ist ein Bodenbereich (z.B. eines Schwimmbeckens) zu erkennen, bei dem z.B. zwei Fliesenbereiche 20 aneinanderstossen. Entlang einer Dehnungsfuge, die hier senkrecht auf der Zeichnungsebene steht, wurde ein Dichtband 17 verlegt. Dieses Dichtband 17 ist durch eine dicke schwarze Linie dargestellt. Ein Schnittschutzstreifen 10 ist flächig vor dem Dichtband 17 montiert. Es sind zwei Fliesen 20 gezeigt, die mittels eines Fliesenklebers 18 angebracht wurden. Zwischen den beiden Fliesen 20 ergibt sich eine Dehnungsfuge, die hier mit einem grau dargestellten Fugenmaterial 19 versehen ist. Der Schnittschutzstreifen 10 kann auch aussermittig angebracht werden. Fig. 8 shows another possible installation situation in a highly schematic form. It can be seen a floor area (eg a swimming pool), in which, for example, two tile areas 20 abut each other. Along an expansion joint, which stands here perpendicular to the plane of the drawing, a sealing tape 17 has been laid. This sealing tape 17 is represented by a thick black line. A cut protection strip 10 is mounted flat in front of the sealing strip 17. Two tiles 20 are shown, which were attached by means of a tile adhesive 18. Between the two tiles 20 results in an expansion joint, which is provided here with a gray joint material 19 shown. The cut protection strip 10 can also be mounted off-center.

Vorzugsweise kommt bei allen Ausführungsformen eine Metall-Gitterstruktur als Gitterstruktur 11 mindestens für die Längsstreifen 16.1, 16.2 zum Einsatz, da ein solches Material schnittfest, biegsam und in Fliesenkleber oder -mörtel 18 einbettbar ist.Preferably, in all embodiments, a metal grid structure is used as the grid structure 11 at least for the longitudinal strips 16.1, 16.2, since such a material is cut-resistant, flexible and can be embedded in tile adhesive or mortar 18.

Eine Metall-Gitterstruktur, falls diese zum Einsatz kommt, kann bei den entsprechenden Ausführungsformen Löcher, Ausnehmungen oder Maschen aufweisen, die kleiner sind als 5 mm.A metal grid structure, if used, may in the corresponding embodiments have holes, recesses or meshes smaller than 5 mm.

  • a tissue,
  • a braid (see, eg FIGS. 6A, 6B, 6D, 6E )
  • a perforated grid (see eg Fig. 6F ), or
  • a scrim (preferably from several layers) serve.

Kevlar mit Harz) als Grundmaterial der Längsstreifen 16.1, 16.2 umfassen, wobei diese Materialien, respektive die Längsstreifen 16.1, 16.2 schnittfest ausgelegt sein müssen.In all embodiments, the cut protection strip 10 can also comprise a flat plastic, metal or composite material (for example Kevlar with resin) as the base material of the longitudinal strips 16.1, 16.2, wherein these materials, respectively the longitudinal strips 16.1, 16.2, have to be cut-resistant.

Der Schnittschutzstreifen 10 kann bei allen Ausführungsformen auch z.B. einen Längsstreifen 16.1 als Metall-Gitterstruktur 11 und einen Längsstreifen 16.2 als flächiges Kunststoff-, Metall- oder Verbundmaterial umfassen, wobei diese beiden Längsstreifen 16.1, 16.2 durch einen flexiblen Materialstreifen 15 verbunden sind (analog zu Fig. 5B).The cut protection strip 10 may in all embodiments include, for example, a longitudinal strip 16.1 as a metal grid structure 11 and a longitudinal strip 16.2 as a sheet plastic, metal or composite material, these two longitudinal strips 16.1, 16.2 are connected by a flexible strip of material 15 (analogous to Fig. 5B ).

Die Schnittfestigkeit kann bei allen Ausführungsformen durch Zugabe/Beimengung von Fasern, Kugeln oder Granulat im Kunststoffmaterial oder im Verbundmaterial erzielt werden.The cut resistance can be achieved in all embodiments by addition / addition of fibers, spheres or granules in the plastic material or in the composite material.

Der Schnittschutzstreifen 10 kann bei allen Ausführungsformen eine Streifenbreite bs der Längsstreifen 16.1, 16.2 aufweisen, die zwischen 2 cm und 20 cm beträgt.The cut protection strip 10 may have a strip width b s of the longitudinal strips 16.1, 16.2, which is between 2 cm and 20 cm in all embodiments.
