Description

Description: The invention relates to a cut protection which is specially designed for use in the damp or wet area of a building. In particular, it is about a cut protection that can be used in the region of a joint to protect a sealing layer from mechanical injury or destruction. It is also about a building area, which is provided with such a cut protection.

There are joints in and on buildings, which are provided with a mostly elastic grout. Such joints can be found e.g. in the transition area between a floor covering and a wall covering or in the area between or behind a sanitary installation and a wall or a floor. For example, joints are also used as expansion joints in areas where large areas are divided.

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. Thus, e.g. A sealing tape or connecting band can be cut or a liquid seal or a special seal can be cut through. As a result, moisture, e.g. enter a building area (e.g., a wall).

In order to protect such a sealing plane (for example, a sealing tape, connecting band, a liquid seal or a special seal) from mechanical destruction, a cut protection can be arranged on the room side before or on the sealing plane.

Materials that are typically considered cut-resistant often have properties that make them unsuitable for wet or wet applications. One of the problems presented here is that a suitable cut protection may only have a small thickness (for example 0.5 to 3.5 mm) in order to be integrated into the wall or floor structure in the area of a joint. Furthermore, cut protection should be flexible so that it can be used e.g. Can be adapted locally to the local installation situation during installation. In addition, it is considered ideal if a cut protection in wound form could be supplied to then unwound during installation and a suitable length to be separated.

Furthermore, cut protection materials are usually sharp-edged when they are made thin. This can lead to injuries due to improper handling. Moreover, careless installation may result in a sharp edge of the cut protection hitting the material of the sealing plane (e.g., a sealing web or a connecting band). For grid structures used as cut protection, sharp wires or portions at the edges may occur, which may lead to similar installation problems.

It has as its object to provide a cut protection that can be handled well. In particular, the cut protection should be able to be combined with a wide variety of sealing levels such as sealing tapes, connection tapes, liquid seals and special sealing, which are available on the market.

This object is achieved by a cut protection according to claim 1 and by a building area according to claim 15. Advantageous embodiments can be found in the respective dependent claims.

The cut protection is designed in all embodiments for use in wet and wet areas of a building, wherein the cut protection comprises: - at least one cut protection strip made of a first material, since cut-resistant, the cut protection strip has two longitudinal edges extending along a strip length the cut protection strip, having a front and a back, and - at least two layers of a second material which is flexible, and which cover at least a part of the front and at least a part of the back of the cut protection strip.

Preferably, in all embodiments, the two layers are made in one piece (i.e., of one and the same material) and form a seam, pocket, casing, or sheath of the cut protection strip (s). By this measure, at least one of the longitudinal edges of the cut protection strip is protected to prevent e.g. during installation, one of the sharp longitudinal edges damages a sealing plane. In addition, depending on the design and arrangement of the portion of the second material, handling improves and facilitates installation.

Preferably, the cut protection strip comprises in all embodiments, a thin, strip-shaped material which is cut resistant. As a thin material is considered in the context of the invention, a material having a thickness which is in the range between 0.2 mm and 2.9 mm.

Preferably, in all embodiments, the two layers cover both the front side and the back side of the cut protection strip and the material of the two layers overlaps in an overlapping region. The material of the two layers can also be butt to shock in all embodiments. These embodiments are particularly robust and easy to handle.

In all embodiments, the cut protection preferably comprises, in addition to the two layers, at least one insert, overlay, additional layer or adhesive layer which extends along at least one partial region of the front side and / or the back of the cut protection strip. By using an insert, overlay or additional layer, the properties of the cut protection can be specifically adapted to the installation situation. Thus, e.g. the surface of the cut protection strip may be made adhesive (e.g., for an adhesive or mortar) or embedding in a liquid seal may thus be made possible. Through the use of an insert, overlay or additional layer, however, it can also be purposefully prevented that e.g. An adhesive or mortar sticks in places where it should not adhere.

In all embodiments, the cut protection preferably comprises, in addition to the two layers, at least one carrier material which is directly or indirectly connected to the cut protection strip (s). The carrier material, which is preferably flexible and / or elastic, may e.g. facilitate the installation of the cut protection.

Preferably, the cut protection in all embodiments in addition to the cut protection strip of the first material comprises a further cut protection strip, wherein the two cut protection strips are arranged so that they overlap in an overlapping region.

Preferably, the cut protection comprises in all embodiments in addition to the cut protection strip of the first material another cut protection strip, wherein the two cut protection strips are arranged so that there is a longitudinal bead, longitudinal groove or gap between the two cut protection strip / is. These two cut protection strips can be in all embodiments and shock to shock.

The further (second) cut protection strip may in all embodiments also consist of the first material, or it may comprise a different material. One of the two cut protection strips may e.g. comprise a metal as a material (e.g., in the form of a grid) and the second cut protection strip may comprise a metal sheet (e.g., CNS).

Preferably, in both embodiments, the two cut resistant strips are hinged together (e.g., by a backing material and / or by an adhesive layer), e.g. to allow a corner installation.

Preferably, the cut protection strips are hinged together in all embodiments by including in the region of the longitudinal bead, longitudinal groove or gap an adhesive layer, adhesive sheet or adhesive tape which connects the two cut protection strips hinged together.

For all embodiments, the following materials or combinations of two of the following materials are particularly suitable for the cut protection strip (s): - Metal - plastic (eg thermoplastic elastomer (TPE) or rubber, or polyvinyl chloride (PVC), for example) - composite materials (a material of two or more bonded materials that have different material properties) The first material can be used in all embodiments in one of the following forms: strip, tape or profile (eg a metal strip or plastic tape) - grid - perforated grid - expanded metal - mesh - knitted fabric - scrim - braid - fiber mat For all embodiments, the following material forms or constellations are particularly suitable for the two layers: - nonwoven - net - knitted fabric - woven fabric - Scrim - fiber mat - film - web or strip (eg an adhesive) [0023] Preference The cut protection strip and / or at least one of the two layers in all embodiments comprises a structured region in which the surface is changed. By this measure, e.g. the adhesion of the cut protection strip and / or the layer (local) can be adjusted. By this measure, however, can e.g. also make the material locally penetrable, e.g. to allow embedding in a liquid seal, or e.g. to prevent sticking locally.

Further details and advantages of the invention will be described below with reference to embodiments and with reference to the drawings. It should be noted that the drawings are not to scale. Above all, the thicknesses of the various elements are not shown in real relationship to each other.

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, wandab-facing surface or a wall-parallel assembly is the speech.

The invention will be described below with reference to some embodiments.

It is generally about a cut protection 10, which has a strip length Lx (parallel to the x-axis) and a perpendicular strip width b (parallel to the z-axis). The cut protection 10 biases a plane E, but may be transferred out of this plane E to an angled position depending on the installation situation (see, e.g., Figures 1C, 1D and 7B).

In most embodiments, the cut protection 10 is sufficiently flexible that it can be used e.g. also around corners or radii can be led around.

The cut protection 10 can be supplied on a roll or as a rod product. An example of a cut protection 10 that can be supplied as a rod product is shown in FIG. 6G.

In the figures, various embodiments are shown. The features of the individual embodiments can also be combined with each other.

The cut protection 10 is designed in all embodiments specifically for use in the wet and wet area 100 of a building. There are numerous installation variants that are covered or made possible by the cut protection solutions 10 of the invention. In principle, the following four installation variants are distinguished: - Installation of the cut protection 10 in the tile adhesive or mortar; Incorporation of the cut protection 10 in a sealing plane 6 (e.g., in a liquid seal of a sealing plane 6); Incorporation of the cut protection 10 together with a component or layer of a sealing plane 6 (for example, the cut protection 10 may be factory-connected to a sealing or termination tape); - Combination of the cut protection 10 on site with a component or layer of a sealing plane 6 (e.g., by adhering the cut protection 10 to a sealing or connecting tape).

The cut protection 10 of the invention is specially designed to enable the said four installation variants.

Primarily this is cut protection solutions that are designed for corner installation in a building area 100. However, the cut protection solutions of the invention can also be used in other building areas 100. Since the installation in the corner area brings with it special requirements, here mainly examples of the corner installation are shown (see, for example, Figures 1C and 7B) and described.

The cut protection 10 preferably comprises at least one cut protection strip 10.1 or 10.2. The cut protection solutions 10 with only one cut protection strip 10.1 or 10.2 are referred to herein as single-strip solutions. Cut protection solutions 10 with two cut protection strips 10.1 and 10.2 are referred to here as two-strip solutions. Both single-strip and two-strip solutions are suitable for corner installation. Since in the corner installation in most cases the joint 4 is either in the vertical area in front of a wall 1 or in the horizontal area above a floor 2, it is sufficient if the cut protection strip 10.1 or 10.2 of the cut protection 10 either in front of the wall 1 (see Fig. 1C) or before the bottom 2 (see Fig. 1D) is located.

The cut protection strip 10.1, 10.2 comprises a first material 5 which is cut-resistant. The cut resistance results either from the properties of the material 5 and / or the cut resistance results from the structure of the material 5.

The cut protection strip 10.1, 10.2 has two longitudinal edges 22.1,22.2, which extend along the strip length Lx. In addition, the cut protection strip 10.1, 10.2 has a front and a back.

In addition to the cut protection strip 10.1, 10.2, the cut protection 10 comprises at least two layers 11, 12, 14, 15 which are flexible. The two layers 11, 12, 14, 15 cover at least part of the front side and at least a part of the rear side of the cut protection strip 10.1, 10.2. Preferably, the two layers serve as a hem or edge 11 or as a casing or casing 12, as shown and described below by way of example.

Preferably, the two layers extend at least along one of the longitudinal edges 22.1, 22.2 of the cut protection strip 10.1, 10.2.

Fig. 1A shows a schematic plan view of a short length of a first exemplary cut protection 10 of the invention in a single strip embodiment. The cut protection 10 typically has in all embodiments a strip form with a strip length Lx (parallel to the x-axis), e.g. can be several meters. The stripe width b extends parallel to the z-axis as shown in Fig. 1A. The strip length Lx and the strip width b span a plane E which is parallel to the x-z plane here. FIG. 1B shows a schematic section through the cut protection 10 of FIG. 1A. The plane E is perpendicular to the plane of the drawing in FIG. 1B. Referring to Figures 1A, 1B, 1C and 1D, an optional substrate 15 is shown.

Adhesive connections are only partially shown in the figures. It will be understood hereinafter that most of the layers, elements and components of the cut protection 10 of the invention are joined together by adhesive bonds and / or stitching connections (e.g., by a seam), even though not shown everywhere.

The layers, elements and components of the cut protection 10 of the invention may be provided in all embodiments, partially or completely with an adhesive region.

The cut protection 10 may be provided in all embodiments along at least one longitudinal edge with a kind of seam or edge 11, as shown with reference to FIGS. 1A, 1B and 1C. In this case, the two layers are part of a seam or edge 11 which has a longitudinal extension (parallel to the x-axis) corresponding to the strip length Lx.

That is, the term "seam" is used here for constellations in which at least one longitudinal edge (eg the longitudinal edge 22.2 in Fig. 1A) of a cut protection strip 10.1, 10.2 with a (second) material (eg nonwoven or film) is lined , such as in FIGS. 1A, 1B and 1C.

The embodiments of Figs. 1A, 1B and 1C are cut protection embodiments lined with a strip-shaped second material. The strip-shaped second material forms a pocket-like hem or edge 11 in the context of the invention.

FIG. 1C shows a schematic sectional view of a building area 100 with the cut protection 10 of FIGS. 1A, 1B. This is a constellation in which the joint 4 is in the area of the wall 1. Accordingly, the cut protection strip 10.1 is arranged vertically in space. The floor 2 and the wall 1 are here provided with a sealing plane 6, e.g. was created by the orders of a liquid seal. The optional carrier material 15 of the cut protection 10 extends along the wall 1 and was laid at a 90-degree angle along the bottom 2. If later a grout (not shown) to be removed, which sits in the joint 4, the cut protection strip 10.1 protects the sealing plane 6 in the region of the wall first

FIG. 7A shows a schematic section through another embodiment comprising a textured cut protection 10 and an optional adhesive layer, web or adhesive strip 17. Furthermore, this cut protection 10 may comprise an optional carrier material. The adhesive layer, web or adhesive strip 17 can serve to stabilize the structured cut protection 10.

The structured cut protection 10 comprises a longitudinal bead or longitudinal groove 18. This longitudinal bead or longitudinal groove 18 may e.g. can be produced by removing material 5 of the cut protection strip, or by bringing the material 5 of the cut protection strip into the corresponding shape already during production (for example by extrusion of a suitable plastic profile).

For the embodiment of Figures 7A and 7B, a plastic material (e.g., PVC, rubber / TPE) or metal that is cut-resistant is suitable.

The aforementioned longitudinal bead or longitudinal groove 18 makes it possible to transfer the cut protection 10 into an angled position (see FIG. 7B) in order to then mount it in a corner region. Preferably, the longitudinal bead or longitudinal groove 18 is designed so that its edges are mitred. In the angled position thus results in a tight connection in the corner (see Fig. 7B).

The cut protection 10 of FIGS. 7A, 7B can in all embodiments comprise a material strip 15, which serves as a carrier of the cut protection 10. The material strip 15 can serve for better handling of the cut protection 10. But it can also be designed so that the strip of material 15 is embeddable. In this case, e.g. a fleece, net or fabric as material strip 15.

Various embodiments or modifications of the principle of Fig. 7A are shown with reference to the enlarged views of Figs. 7C, 7D and 7E. The cut protection 10 of FIG. 7C is designed so that two separate cut

Protective strips 10.1, 10.2 by an additional layer or film 19 (or by an adhesive 17, as in Fig. 7A) are held together articulated. The cut protection 10 of FIG. 7D is designed so that the two cut protection strips 10.1, 10.2 are connected to each other throughout. At the lowest point of the longitudinal bead or longitudinal groove 18, the two cut protection strips 10.1, 10.2 connected by a kind of longitudinal ridge 23 with each other.

The cut protection 10 of FIG. 7E is also designed so that the two cut protection strips 10.1, 10, 2 are connected to each other throughout. At the lowest point of the longitudinal bead or longitudinal groove 18, the two cut protection strips 10.1, 10.2 are connected to each other by a kind of projection 20.

The two cut resistant strips 10.1, 10.2 of Figures 7D and 7E are continuous (integral) and therefore need not necessarily have an additional layer (e.g., adhesive 17 or foil 19) for hinged connection.

FIGS. 8A to 8F and 8H show (cut resistant) materials 5 having different lattice structures. These materials 5 or lattice structures are suitable for both single-strip and two-strip embodiments of the invention. Preferably, the lattice structures are metal or plastic or composite lattice structures. Fig. 8G shows a cut-resistant plastic material 5 whose (surface) structure is rough due to the addition or addition of an additive (e.g., corundum) (for example, to allow bonding with an adhesive). In Fig. 8H, a plastic fiber material (e.g., Kevlar fabric) is shown.

But it is also possible, the structured cut protection 10 respectively the / the cut protection strips 10.1, 10.2 in the area of the edge strips porous, open-pore interpreted or to provide him there with holes to the structured cut protection 10, for. to embed in a liquid seal.

Since the materials which are suitable as cut protection material 5 are in some cases not suitable for e.g. To be permanently connected to other materials, some embodiments are described below, the surface of which has been at least partially structured. The corresponding area is also referred to here as a structured (longitudinal) area 21. The term "structured" is to be interpreted broadly here. For example, a structured area 21 is an area that is etched, sandblasted, or e.g. roughened by grinding (in these cases material is removed). However, a region 21 can also be structured by e.g. Material is applied, such. by sanding, coating, coating, etc. A structured region 21 can also be provided by perforating, perforating or punching the material, to name a few further examples.
