Description

Description [0001] The invention relates to building areas with an expansion joint and with a cut protection. In particular, it is about damp and wet rooms in or on a building. It is also about an assembly or a mounting kit for mounting room side in an expansion joint of a building.

There are dilatation joints in and on buildings, which are provided with a mostly elastic grout. Such dilation joints are provided, for example, in areas where different materials (e.g., parquet and stone floor) meet. But dilatation joints are also used e.g. provided in the floor area to subdivide floating floor coverings. In the sanitary area and in swimming pools, dilatation joints are also frequently used. Furthermore, joints that can stretch are also e.g. provided in the transition region between a floor covering and a wall covering, as well as in room corners, to name but a few exemplary areas. In the following, the term expansion joint is used for dilatation joints and other joints on and in buildings, which show a stretching behavior.

If there are strains in the region of an expansion joint, it may happen that the grout breaks or dissolves. The grout can also have become unsightly with age. Then the grout is often cut out by means of a carpet knife from the joint, before then new grout is introduced. This can lead to damage or even destruction of underlying layers. Thus, e.g. a sealing tape can be cut or a liquid seal or a special seal can be cut through. As a result, moisture, e.g. penetrate into the underlying trades of the building. From the document DE 102010050752 A1 an embodiment with a tub belt with a pocket is known (see FIG. 8 there), in which a cut protection can be inserted. In this embodiment, it is concretely a solution that can be used in the field of a bathtub. From this document, another embodiment is known (see Fig. 13), which relates to a solution for covering a floor joint, wherein tiles rest flat on the tape shown.

The document US2010307093A1 shows various expansion joints. However, these expansion joints are not described in connection with expansion joints and no cut protection is shown in document US2010307093A1.

From the document EP3138452A1, which is considered as older but post-published prior art, an expansion joint is mentioned in connection with FIG. 8, which results between two tiles. A cut protection strip sits above a sealing strip. However, this document does not describe a sealing plane covering an expansion joint. It also describes no cut protection, which is floating.

It turns the task to prevent such damage. That It is all about protecting the sealing plane, which is typically located in the area of the affected expansion joint below the grout.

This object is achieved for buildings by a suitable combination of cut protection and sealing level according to claim 1. A corresponding use of a corresponding cut protection strip can be found in claim 11. Advantageous embodiments are contained in the subclaims.

According to the invention, a building area, in particular a wet and wet area of a building, having a floor or wall structure, which has an expansion joint, so equipped, [0009] that along the expansion joint, a sealing plane is provided which the expansion joint and which is (trans-) stretchable at least in a region along the expansion joint, and [0010] that a cut protection is arranged in front of the sealing plane on the room side or is directly or indirectly connected to the sealing plane on the room side, that the cut protection along the expansion joint and that the cut protection is floatingly mounted so as to be movable in the event of movement of the floor or wall structure relative to the sealing plane, a floating mounting comprising installation situations, - in which the cut protection is due to its construction and / or due to the assembly in the floor or wall construction is movable relative to the sealing plane, in which the section Protection has no or only a small relative mobility, because the cut protection is temporarily attached with a pressure-sensitive adhesive or other tacking connection.

The cut protection of the invention can sit in all embodiments of the room side before the sealing plane, without being connected to the sealing plane.

The cut protection of the invention can sit in all embodiments of the room side before the sealing plane and either connected directly to the sealing plane or be indirectly connected by means of a (adhesive) adhesive or other tack connection with the sealing plane.

The cut protection of the invention sits in all embodiments, preferably in the region of a longitudinal edge temporarily adhering in an adhesive or mortar to be movable in the event of movement of the floor or wall structure relative to the sealing plane.

The cut protection may comprise in all embodiments a metal strip (eg a CNS metal strip or a grid), a plastic strip or a composite strip as strips of cut-resistant material, preferably the material of this strip due to its material properties in all embodiments protection against damage or cutting the cut protection with a sharp object (eg a knife).

The cut protection may comprise in all embodiments a strip, two strips, or more than two strips of a cut-resistant material or a cut-resistant structure. If the cut protection comprises two strips, then these two strips can at least partially overlap in an overlapping area such that the two strips are movable relative to one another if transverse forces occur in the area of the expansion joint. In all embodiments, the cut protection can have an area along at least one longitudinal edge, which prevents a permanently fixed gluing or anchoring of the longitudinal edge in an adhesive or mortar. In other words, this area ensures that the cut protection is either not retained in the adhesive or mortar at all, or that the cut protection only temporarily adheres to the adhesive or mortar in the region of the expansion joint until the occurrence of a transverse force. For this purpose, the cut protection can e.g. be completely or partially covered or covered with a suitable material.

The cut protection may comprise a (adhesive) adhesive in all embodiments or be connectable with a (adhesive) adhesive. This adhesive may be designed to bond the cut protection to a surface or region of a sealing plane (e.g., a sealing tape), the adhesive allowing movement of the cut protection relative to the sealing plane if transverse forces occur in the area of the expansion joint.

However, this adhesive can also be designed to connect the cut protection with a carrier material (for example with a fleece) in order to be able to handle and assemble the cut protection more easily.

The cut protection can in all embodiments at least in the region of a partial surface by means of another tacking connection (instead of a (adhesive) adhesive) with a component, e.g. be connected to a carrier material or with a member of the sealing plane, wherein the stitching connection allows movement of the cut protection relative to the component of the sealing plane, if lateral forces occur in the region of the expansion joint. Especially as

Stapling compound is suitable, for example, a longitudinal seam.

The cut protection can be designed in all embodiments in the region of the back and / or front (full-surface or only in the area of a partial surface) self-adhesive or self-adhesive.

The cut protection can be used in all embodiments, e.g. also be mounted along a bathtub, a shower tray, a shower tray or a (shower) gutter.

The cut protection may in all embodiments comprise at least one strip of material (e.g., a substrate) which, when assembled, is firmly seated in an adhesive or mortar. Here, the material strip and / or the connection of the cut protection with the material strip (for example, by a longitudinal seam or adhesive adhesive) is designed so that when a transverse force occurs in the expansion joint of the strip of material yields or ruptures, or that occurs when a Transverse force in the region of the expansion joint separates the cut protection from the strip of material (for example, by releasing the adhesive or by tearing the longitudinal seam), so that the cut protection can move relative to the sealing plane.

The cut protection may in all embodiments include a metal strip (eg, chrome-nickel steel, CNS steel) or plastic strips (eg, a thermoplastic elastomer and / or polypropylene and / or polyvinylchloride (PVC), to cite some examples) or a composite strip , Particularly suitable are lattice or net-like material strips (for example of metal).

The cut protection according to the invention can be designed in all embodiments as a one-piece / one-piece cut protection which consists entirely of a cut-resistant material (apart for example from any adhesives and / or seams for fastening).

The cut protection may comprise multiple strips (multi-strip embodiment) or regions of at least two different materials in all embodiments.

The cut protection may comprise an additional material in all embodiments to protect the cut protection against permanent sticking in the mortar or adhesive so that it is movable at the latest when a lateral force occurs.

The cut protection may in all embodiments be connected in whole or in part to a sealing plane (for example with a sealing tape).

The sealing plane may in all embodiments comprise a layer of a stretchable material, wherein in the mounted state, at least one longitudinal region along the dilatation joint is stretchable.

In all embodiments, the sealing plane can comprise a stretching zone which extends along the dilatation joint and which can be stretched transversely to the longitudinal direction of the dilatation joint.

The sealing plane may in all embodiments include a virtual expansion zone, which results from the fact that a flexible material forms a longitudinal loop or a longitudinal bag, wherein when a lateral force occurs, this longitudinal loop or this longitudinal bag pulls taut. Such a virtual stretch zone is preferably used in the area of corners.

The sealing plane may comprise a self-healing plastic material in all embodiments.

Particularly suitable as sealing material of the sealing plane and can be used in all embodiments are materials or combinations of materials that have a permanent elasticity.

The cut protection of the invention is preferably used or mounted in such a way that the cut protection in the installed state is parallel to the sealing plane viewed from the room side, the cut protection either directly with the sealing plane

Sealing layer is connected (for example by means of a sticking adhesive or another tack connection) or that the cut protection is arranged separately from the sealing plane; [0036] - the cut protection is integrated into the sealing plane.

According to the invention, embodiments (e.g., in the form of an assembly or assembly unit) are provided which are particularly suitable for use in the field of sanitary rooms, kitchens, spa areas and swimming pools. The cut protection of the invention can be used particularly advantageously in the field of sanitary installations (for example in bathrooms or in public toilets or shower areas), kitchens, swimming pools, saunas and in other similar areas.

The preferred application areas in or on buildings are summarized here with the term "wet and wet area".

It is an advantage of the cut protection solution of the invention that it can be combined with sealing tapes, sealing solutions, liquid waterproofing, sealing slurries of various types and manufacturers.

The cut protection can be part of an assembly or assembly unit in all embodiments. In this case, the cut protection is e.g. is connected to an element (e.g., a sealing tape) of a sealing plane or is designed to be joined to an element (e.g., a sealing tape) of a sealing plane.

However, the cut protection can also be part of a group in all embodiments. In this case, the cut protection is e.g. bonded to a substrate to facilitate handling and installation.

In all embodiments, the cut protection together with the sealing plane in the installed (mounted) state form a functional unit, this functional unit provides particularly good and lasting results. The cut protection sits in the mounted state either on the room side in front of the sealing plane and protects due to its cut resistance structures of the sealing plane, or it is integrated on the room side in the sealing plane to protect the layer / layers or the material of the sealing plane.

The cut protection may comprise a (planar) grid structure in all embodiments. Particularly suitable is a metal grid structure, a plastic grid structure, a fabric grid structure or a fiber grid structure.

The cut protection may include in all embodiments, a (solid) network, knitted fabric, woven, braided, fiber mat, perforated grid, expanded metal or scrim.

The term "strip" is intended to indicate that the geometry of the cut protection and / or the sealing plane in one direction, the so-called "strip longitudinal direction", extends far, while the measured perpendicular thereto width and thickness of the strip are smaller. Typically, the cut protection transverse to the strip longitudinal direction has a cross-section with a width which is (several times) greater than the thickness of the strip.

The width of the cut protection can be in all embodiments, for example, between about 1 cm and 20 cm.

Its thickness may typically be between about 0.29 mm and 2.9 mm in all embodiments.

The cut protection can be single-layer, two-ply or multi-ply in all embodiments.

The cut protection of the invention can be handled well and easily. In particular, the cut protection can be combined with a wide variety of sealing tapes and sealing solutions that are available on the market.

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 be able to better narrow down the location and direction information, a reference to a room (also referred to as a room page) is also partially made, in which e.g. from a room-side element is the speech.

The invention will be described below with reference to some embodiments. It should be noted that there are, in principle, the following two basic approaches A and B, e.g. differ in the assembly. Where this was meaningful and possible, it is indicated in the figures whether the solution shown is to be assigned to approach A or approach B. This assignment is only for clarity and it should not be understood as limiting. Illustrations that are not labeled with either A or B can be used in both Approach A and Approach B. Embodiments that are assigned to the approach B, but can also be assembled before assembly accordingly from separate products (semi-finished products) and then similar to those embodiments that are supplied as a kit or assembly 70 substantially.

Adhesive bonds are only partially shown in the figures. It will be understood hereinafter that most of the layers, elements and components of the cut protection 30 of the invention are joined together by adhesive bonds and / or stitching connections (e.g., by a seam), although not shown everywhere.

The layers, elements and components of the cut protection 30 of the invention may be provided in all embodiments, partially or completely with an adhesive region.

The cut protection 30 can be supplied on a roll or as a rod product.

In Fig. 1A, a first exemplary installation situation is shown. FIG. 1A is a first basic approach A, in which a cut protection 30 is implemented separately from a sealing plane 20. In the embodiments of the approach A, the cut protection 30 can be mounted directly on or at the sealing plane 20 prior to installation or installation, or the cut protection 30 is physically mounted separately from the sealing plane 20 (FIGS. 1A, 1B and 1C show such embodiments) spatially separate mounting of the cut protection 30).

The bottom structure, which is provided with the reference numeral 10, can also be embodied other than shown in Figures 1A, 1E and 1H.

In the figures 1A to 1D, and 1F and 1G is schematically indicated that in the area between the two tiles 6 typically a grout 11 (eg in the form of a silicone joint) is introduced to close the expansion joint 7 and against penetrating water to protect.

In FIG. 1B, the cut protection 30, as also in FIG. 1A, is arranged separately from the sealing plane 20 in the region of a tile adhesive or mortar 5.

In Fig. 1C, the cut protection 30 is adhered to a substrate 61 (here by means of a (adhesive) adhesive 26). The cut protection 30 is arranged together with the carrier material 61 in the region of a tile adhesive or mortar 5.

In FIG. 1D, the cut protection 30, as also in FIG. 1A, is arranged separately from the sealing plane 20 in the region of a tile adhesive or mortar 5. However, the cut protection 30 is here completely surrounded / encased by a material 29 so that the cut protection 30 can be released from the tile adhesive or mortar 5 at the latest when a lateral force occurs. The sealing plane 20 here has no stretch zone in the classical sense, but a virtual expansion zone, which is formed by the formation of a longitudinal pocket or fold 27 in the material of a sealing sheet.

Further exemplary installation situations are shown in FIGS. 1E, 1F and 1G. These figures concern the second basic approach B, in which a cut protection 30 together with a sealing plane 20 forms an assembly unit or assembly 70. In the embodiments of approach B, the cut protection 30 is assembled together with at least one element (e.g., along with a sealing tape 22 or 24) of the sealing plane 20.

In Fig. 1F, the cut protection 30 is bonded to the sealing plane 20 by means of a (glue) glue 25, or by means of another tacking connection, with a sealing tape (e.g., of stretchable material 24). The sealing tape (e.g., of stretchable material 24) may be placed in a seal (e.g., a liquid seal) and / or in a layer of mortar or adhesive 5.

The cut protection 30 of Fig. 1F may e.g. comprise a grid which is wholly or partially provided with a butyl strip to seal the grid by means of the butyl strip e.g. to be able to stick to a region of the sealing plane 20. Optionally, the grid can be provided on its side of the room with a cover, which prevents penetration of mortar or adhesive in the openings of the grid.

In FIG. 1G (similar to FIG. 1E), the cut protection 30 is connected to the expansion zone 24 of a sealing band of the sealing plane 20 by means of a (adhesive) adhesive 25 or by means of another stitching connection. The sealing tape may be placed in a seal 4 (e.g., a liquid seal) and / or in a layer of mortar or adhesive 5.

FIG. 1H shows a further exemplary installation situation. It is also in Fig. 1H to the second basic approach B, in which a cut protection 30 forms a mounting unit or assembly 70 together with a sealing plane 20.

The cut protection 30 is here asymmetrically mounted in a corner region (transition region between a floor and a wall) to protect here an expansion joint 7, which separates a floating screed area 3 from a wall structure. Preferably, in the area of the expansion joint 7, the sealing plane 20 is here designed with a longitudinal pocket or fold 27, as shown in FIG. 1D.

It is in all embodiments to a building area 100, which has a Dilatationsfuge 7 or another joint with extensibility (collectively referred to as expansion joint). In particular, it is about the wet and wet area of a building. The invention can be used particularly advantageously in such a moist and wet area.

The building area 100 has a floor and / or wall structure 10, as shown by way of example in FIGS. 1A, 1E and 1H.

In the following, primarily installation situations are described and shown, which are located in the floor area. However, the description of the corresponding embodiments can also be applied without problems to installation situations in the wall area and / or in the transition area between two walls and / or in the transition area between a floor and a wall.

The floor area in the installation situation of Figs. 1A, 1E and 1H, viewed from the bottom up, has the following exemplary floor structure 10 (the elements of Figs. 1A, 1E and 1H are not drawn to scale): Concrete floor or subfloor 1, which may be inside a building or outside the building, for example.

Insulation layer 2, which may comprise one or more layers. The insulating layer 2 may be e.g. serve the impact sound insulation.

Screed 3, which was applied floating on the insulating layer 2 here. The screed 3 comprises in the example shown an expansion joint 7 which extends parallel to the x-axis in the plane of the drawing. Such an expansion joint 7 is e.g. designed to divide larger screed surfaces, so that expansion movements do not lead to cracks or warping. Optionally, foam 8 (e.g., in the form of a round cord) is introduced into the expansion joint 7, as exemplified and indicated schematically in FIGS. 1A and 1E.

A seal 4 seals the top of the screed 3 from here. Such a seal 4 may e.g. be introduced as a liquid seal. There are also numerous other solutions to create the seal 4.

Tile mortar or adhesive 5 is used on the seal 4 in order to attach tiles 6 or other coverings can.

The installation situation according to the invention is characterized in particular by the fact that a sealing plane 20 is provided at least along the expansion joint 7, as shown by way of example and schematically in FIGS. 1A, 1E and 1H. The sealing plane 20 covers the expansion joint 7 and is (transversely) extensible at least in a region along the expansion joint 7 or has a longitudinal pocket or fold 27 (here called the virtual expansion zone), as shown schematically in FIG. 1D.

The installation situation according to the invention is further distinguished by the fact that a cut protection 30 is arranged on the room side in front of the sealing plane 20, as shown by way of example and schematically in FIGS. 1A, 1B, 1C, 1D, 1E, 1F, 1G and 1H. The cut protection 30 extends along the expansion joint 7 and it is floatingly mounted so that it is movable in the event of movement of the floor or wall structure 10 relative to the sealing plane 20. However, the cut protection 30 can also be integrated on the room side into a layer or component of the sealing plane 20.

This form of assembly of the cut protection 30 is referred to herein as floating mounting. The floating assembly includes both installation situations in which the cut protection 30 due to its structure and / or due to the assembly in the floor or wall structure 10 is movable relative to the sealing plane 20. However, the floating assembly also includes installation situations in which the cut protection 30 during installation has no or only a small relative mobility (eg, because the cut protection with a pressure sensitive adhesive 25 or other stitching connection (eg, a longitudinal seam 28, as shown in Fig. 12) temporarily is attached). In such installation situations, the floating mobility typically results only when the floor or wall structure 10 is moving (e.g., due to a stretching movement). In this case, the adhesive or other staple connections solve.

As the sealing plane 20 here is a region of the floor or wall structure 10 is designated, whose primary function is the sealing against the ingress of moisture. The sealing plane 20 may be e.g. one or more of the following components comprise: [00117] - sealing web, [00118] - sealing film, [00119] - sealing fleece, [00120] - sealing strip, [00121] - liquid sealing, [00122] - sealing slurry, [00123] - epoxy layer.

The sealing plane 20, or at least one component of the sealing plane 20 (e.g., a sealing sheet for insertion or embedding in a liquid seal), may be provided together with the cut protection 30 in all embodiments.

The term "sealing plane" 20 is not intended to be limiting in that it may comprise only a single plane The sealing plane 20 may in all embodiments also comprise more than one plane and / or may consist of more than one material be constructed.

The sealing plane 20 may comprise one or more than one component in all embodiments. Preference is given to sealing levels 20 which are multi-layered, i. that span more than one level or layer.

The sealing plane 20, or at least one component of the sealing plane 20, in all embodiments together with the cut protection 30, a mounting unit or assembly group 70 form (see for example Fig. 1E, 1F, 1G, 1H, 8A, 8B, 8C, 9A , 9B).

However, in all embodiments, the sealing plane 20, or the components of the sealing plane 20, can also be created independently of the cut protection 30 on the floor or wall structure 10, whereby, for example, products from third-party suppliers can be used. An exemplary embodiment with separate cut protection 30 is e.g. shown in Figures 1A, 1B, 1C and 1D.

As a cut protection 30, here is meant a means whose primary function is to protect the sealing plane 20 located behind it from mechanical action (for example by a carpet knife). It protects the sealing plane 20 from damage.

Cut protection 30 may include one or more components in all embodiments. The cut protection 30 may be used in all embodiments e.g. comprise a strip of cut protection material or cut protection structure 32, or it may comprise more than one strip.

The following materials / structures 32 are particularly suitable as cut protection 30: a grid (see eg Fig. 3A), [00133] - a net (see eg Fig. 3C), [00134] - a tissue [See, for example, FIG. 3H], [00135] - a braid, [00136] - a perforated plate (see, eg, FIG. 3D or 3F), [00137] - an expanded metal (see, for example, FIGS. 3B, 3E), [00138] - CNS (chromium-nickel steel) or other metals, [00139] - plastic (eg with granules and / or fibers), [00140] - other materials (eg composite materials of one or more of the aforementioned materials).

[00141] - a scrim / knit (preferably of several layers).

After several exemplary installation situations of the approaches A and B have been described (see FIGS. 1A to 1H) and the essential terms have been defined, further embodiments are described below.

FIG. 2A shows the section through a first embodiment of a component or layer of a sealing plane 20. This is a component, or layer 24, which is extensible as a whole at least parallel to the direction of the z-axis, as indicated in Fig. 2A by the pattern of the layer 24. The corresponding extensibility is also referred to here as transverse extensibility, since this extensibility is directed transversely to the expansion joint 7. The expansion joint 7 extends in all embodiments parallel to the x-axis.

If the component, or layer 24, of FIG. 2A is mounted as shown in FIGS. 1A and 1B, then the extensibility is increased by the application to the seal 4, by the introduction into the seal 4 or by the Insertion in the mortar / adhesive 5 stiffened.

However, it remains at least in a region along the expansion joint 7 is a Querdehnbarkeit.

In Fig. 2B, the section through a second embodiment of a component or layer of a sealing plane 20 is shown. This is a component or layer which comprises an expansion zone 21 in the middle region. The expansion zone 21 may also be off-center in all embodiments. The lateral longitudinal strips 22 of the component or layer may be made of a non-stretchable material, or the stretchability of an elastic starting material may be blocked (eg by coating, laminating or immersing in a stiffer material) or removed (eg by chemical or physical treatment). The expansion zone 21 of FIG. 2B is stretchable at least parallel to the direction of the z-axis.

In Fig. 2C, the section through a third embodiment of a component or layer of a sealing plane 20 is shown. This is a component or layer of a sealing plane 20, which comprises two lateral strips 23 which at least partially overlap a stretchable material 24, whereby here an expansion zone 21 results centrally (or off-center). If the two lateral strips 23 are made of a material which is not stretchable, the stretchability of the material 24 is blocked. As a material for the lateral strips 23, for example, a fleece or fabric is suitable. The expansion zone 21 of FIG. 2C is stretchable at least parallel to the direction of the z-axis.

Preferably, the two lateral strips 23 are designed so that they can be easily embedded in the (liquid) seal 4 and / or in an adhesive / mortar 5 or connected to this / this.

One or both strips 23 may also be arranged on the upper side (here referred to as the room side) of the material 24. The material 24 may also be provided on the room side and on the opposite side (wall or bottom side) with strips 23 (called sandwich structure).

Different materials / structures 32 are shown in FIGS. 3A to 3H, which can be used here as cut protection 30. These materials / structures 32 are suitable for both one-piece / single-strip and multi-piece / multi-strip embodiments of the invention. Preferably, the materials / structures 32 are metal or plastic or composite structures. Fig. 3A shows an exemplary grid, Figs. 3B and 3E show exemplary expanded metals, Fig. 3C shows an exemplary mesh, and Figs. 3D and 3F show exemplary perforated sheets. In Fig. 3G there is shown a cut-resistant plastic material 32 which is cut resistant due to the addition or addition of an additive (e.g., corundum and / or fibers). In Fig. 3H, a fibrous material (e.g., Kevlar fabric) is shown.

Fig. 4A shows a schematic plan view of a short length of a first exemplary cut protection 30 of the invention in a one-shot embodiment. The cut protection 30 typically has in all embodiments a strip form having a strip length L (parallel to the x-axis), e.g. may be several meters, and with a strip width b (parallel to the z-axis) as shown in Fig. 4A. The strip length L and the strip width b span a plane parallel to the x-z plane here. FIG. 4B shows a schematic section through the cut protection 30 of FIG. 4A.

The cut protection 30 of the invention typically has a thickness (parallel to the y-axis) that ranges between 0.1 and 4mm.

Fig. 5A shows a schematic plan view of a short length of a second exemplary cut protection 30 of the invention in a two-strip embodiment. There are here two strips are provided which lie in a common plane, which is parallel to the x-z plane here. FIG. 5B shows a schematic section through the cut protection 30 of FIG. 5A. Between the two strips, a gap 53 is provided here. The two strips can be in all embodiments, butt to joint.

The gap 53, if present, may be filled with a material in all embodiments, or the gap 53 may in all embodiments be e.g. be bridged by a (adhesive) strip 48, a cover sheet or other layer of material (see for example Fig. 9C).

Preferably, a bead 38 or a gap 53, if present, in all embodiments serves to be able to install the cut protection 30 in a corner region. In this case, a strip of the cut protection 30 is folded up or bent along the bead 38 or along the gap 53.

Fig. 6A shows a schematic plan view of a short length of a third exemplary cut protection 30 of the invention in a two-strip embodiment. There are provided here two strips which overlap each other in a strip-shaped overlap region 39. FIG. 6B shows a schematic section through the cut protection 30 of FIG. 6A. The overlap area 39 may have a width parallel to the z-axis, which is a few millimeters to a few centimeters in all embodiments.

Fig. 6C will be described later.

Fig. 6D shows a schematic section through a cut protection 30, which is similarly overlapping constructed as the cut protection 30 of Fig. 6A, 6B. In FIG. 6D, however, cut protection 30 has two strips of different materials and / or structures 32 (see FIGS. 3A to 3H). For example, the strip 40 lying on the room side may be made of a smooth material, so that this strip 40 does not stick too firmly in a mortar or adhesive 5, whereas the strip 41 located on the bottom or bottom side is e.g. may comprise a material having particularly good cut protection properties. The strip 40 may be, for example, a (CNS) metal strip or plastic strip (e.g., a foil), whereas the strip 41 may be e.g. may be a (metal) grid strip. When installing the cut protection 30 below tiles 6 or other covering, the strip 40 ensures that the right longitudinal edge of the strip 41 does not or only slightly adheres in the mortar or adhesive 5. This ensures a floating mounting of the cut protection 30 in almost all installation situations.

The cut protection 30 may in all embodiments also comprise one of the flat strips 33, as shown in FIGS. 7A-7E by further examples: The flat strip 33 may have punches 34, as exemplified in FIG. 7A. [00159] FIG [00160] The flat strip 33 may have holes 35, as shown by way of example in Fig. 7E, and / or [00161] - the flat strip 33 may have slots 36, as shown by way of example in Fig. 7B; and / or [00162] The flat strip 33 may have edge slots 37, as shown by way of example in FIGS. 7C and 7D.

Based on the elements and components already described, further exemplary embodiments are derived, reference being made in each case to the description of FIGS. 1 to 7E. In the following, only the essential differences are discussed.

FIG. 8A shows a schematic section through an assembly 70 that includes a cut protection 30 of FIGS. 4A, 4B and a layer or component of the seal plane 20 of FIG. 2A. The cut protection 30 may be joined to the sealing plane 20 by a (glue) glue 25 or other tacking connection to facilitate assembly. However, the cut protection 30 can also be supplied and / or assembled separately from the layer or component of the sealing plane 20. If the cut protection 30 is supplied separately, it may be bonded to the layer or component of the sealing plane 20 prior to installation or during installation (e.g., by a (glue) adhesive 25).

The use of an optional (adhesive) adhesive 25 has the advantage that the cut protection 30 is movable relative to the sealing plane 20 (referred to herein as floating bearing) as soon as transverse forces (parallel to the z-axis) are applied.

The optional (adhesive) adhesive 25 can be used over the whole area, as shown in FIG. 8A, or only in partial areas, as shown in FIG. 8B.

FIG. 8B shows a schematic section through a further assembly or assembly unit 70, which comprises a cut protection 30 according to FIGS. 4A, 4B and a layer or component of a sealing plane 20 according to FIG. 2B. The layer or component of the sealing plane 20 here has a spatially defined expansion zone 24.

FIG. 9A shows a schematic section through a further assembly or assembly unit 70, which comprises a cut protection 30 according to FIGS. 6A, 6B and a layer or component of a sealing plane 20 according to FIG. 2A. The two strips 41 of the cut protection 30 can be connected to the layer or component of the sealing plane 20 by a (adhesive) adhesive 25 or by another stitching connection, in order to facilitate the assembly and to ensure a sufficient overlap in the overlapping area 39 put. In addition, the two strips 41 of the cut protection 30 are movable relative to the layer or component of the sealing plane 20 (referred to herein as floating storage) as soon as transverse forces (parallel to the z-axis) are applied.

FIG. 9B shows a schematic section through a further assembly or assembly unit 70, which comprises a cut protection 30 according to FIG. 6D and a layer or component of the sealing plane 20 according to FIG. 2A. The two strips 40, 41 of the cut protection 30 can be connected to the layer or component of the sealing plane 20 by a (adhesive) adhesive 25 or by a different stitching connection in order to facilitate assembly and to ensure sufficient overlap in the overlapping area 39 to make sure. The strip 40 protects the strip 41 from an adhesive or mortar 5, as already mentioned.

FIG. 9C shows a schematic section through an exemplary group 60 comprising a one-cut cut protection 30 according to FIG. 4B and a carrier material 61. The cut protection 30 is here connected to the carrier material 61 by a (adhesive) strip 25 (preferably an adhesive). This connection is provided here off-center. The cut protection 30 may be entirely or partially upwardly provided with a layer 52 (e.g., a nonwoven or a film).

9D shows a schematic exploded view of a constellation in which a group 60 is used as cut protection 30 according to FIG. 6C and a layer or component of the sealing plane 20 according to FIG. 2B. Such a constellation in which cut protection 30 together with a (fleece or fabric) material strip 61 forms a group 60 is particularly easy to handle. The material strip 61 can serve as a carrier for the cut protection strip 41.

FIG. 9E shows a schematic sectional view of another assembly or assembly 60 comprising a two-strip cut protection (eg, as shown in FIG. 5B) mounted on a component or layer of a seal plane 20 of FIG. 2A and a cover 51 is completely or partially covered. The component or layer of the sealing plane 20 is stretchable at least in the central region 24. Preferably, a cover sheet is used as the cover 51. But it can also be used as a cover 51, a stretchable network. A solution according to Fig. 9E is also suitable for corner installation.

The cut protection strip 41 may in all embodiments by means of a (adhesive) adhesive 26 (see Fig. 1C) and / or by means of another tack connection (eg by means of one or two longitudinal seams 28, see Fig. 12) with the strip of material 61 be connected.

The cut protection 30 may be provided in all embodiments along at least one longitudinal edge with a kind of seam 42, 43, 45, as shown with reference to Figures 10A to 11D. The term "seam" is used here as a generic term for various constellations In the true sense of the word, the embodiments of Figures 11A and 11B are cut protection embodiments having a seam 45. The seam 45 is provided by forming at least one longitudinal edge of the seam Fig. 11C shows a special case in which the seam 45 is designed so as to obtain a double-layered cut protection.

However, the term "seam" is also used here for constellations in which at least one longitudinal edge of the cut protection strip is lined with a layer or a strip 42 of another material (eg fleece or film), as for example in FIGS. 10A, 10B, 10C and 10E, Fig. 10C shows a special case in that the cut protection strip is almost completely lined or encased with a layer or strip 43. Fig. 11D shows a special case where a layer or strip 46 of another material (Example, fleece or film) is designed so that a kind of bag results, in which a cut protection strip 47 can be inserted.

In the following, further details of these embodiments will be described.

In Fig. 10A, a hem 42 of another material is provided on a one-piece cut protection 30 (e.g., as shown in Fig. 4B). In FIG. 10B, two hem strips 42 of another material are provided on a one-piece cut protection 30. In FIG. 10C, a hem 43 of another material is provided on a one-piece cut protection 30, which partially surrounds or sheaths the cut protection 30 (also called sheath or sheath 43 here). The casing or casing 43 may also completely surround the cut protection 30. In Fig. 10D, two hem strips 42 of another material are provided on a one-piece cut protection 30 (as in Fig. 1B). Additionally, an additional layer 44 (e.g., a nonwoven or film) is provided on at least one side of the cut protector 30. In FIG. 10E, two hem strips 42 of another material are provided on a one-piece cut protection 30. Additionally, an additional layer 52 (e.g., a non-woven or film) is provided on at least one side of the cut protector 30.

All embodiments of the invention, on the underside (that side, which is directed in the installed state in the direction of sealing plane 20) and / or on the top (self-) be made adhesive, in which case preferably an adhesive is used, the is temporarily adherent.

The seam 42, 43, 45 (in its various embodiments) and / or the (in) layer 44 and / or the (up) layer 52 may have different tasks or functions. On the one hand, he can e.g. surrounding the sharp longitudinal edge of a cut protection strip. On the other hand, it can additionally or alternatively be designed in all embodiments so that the cut protection 30 does not or hardly adheres to the adhesive or mortar 5. It can thus be ensured that the cut protection 30 can move relative to the sealing plane 20 when transverse forces occur (called floating mounting).

In all embodiments, the cut protection 30 may have at least one folded or double longitudinal edge forming a seam 45, as shown in FIGS. 11A to 11D. In FIG. 11A, a fold-over or double-lying longitudinal edge is provided as a seam 45 on a one-piece cut protection 30. In FIG. 11B, two folded or double lying longitudinal edges are provided as a seam 45 on a one-piece cut protection 30. In Fig. 11C, the one-piece cut protection 30 is made double-lying. Shown in Fig. 11D is a two-strip (or more specifically, a 2-piece) cut protection 30 comprising a double layer or double strip 46 of another material (eg, nonwoven or film), which is a type of (longitudinal) pocket forms. In this (longitudinal) pocket sits e.g. a second strip 47, e.g. is shown in Fig. 4B. The (longitudinal) pocket 46 protects the second strip 47 during installation. As a result, the second strip 47 remains movable relative to the sealing plane 20 (called floating bearing).

In addition, in all of these embodiments, an inlay 44 (see, for example, Fig. 10D) and / or a layup 52 (see, e.g., Fig. 10E) may be provided.

The seam 42, 43 may be printed or labeled in all embodiments. Thus, at the seam 42, 43 e.g. a meter and / or centimeter division are provided, which can be helpful when cutting to a suitable length.

All one-piece, but especially the multi-part cut protection solutions may optionally be provided with one or more strips of another material (e.g., nonwoven or woven fabric). The use of such an additional strip of material is particularly advantageous in the case of multi-part cut protection solutions, since these are used, for example. the two strips 41 of the embodiment according to FIGS. 5A, 5B combine to form a group 60.

In FIGS. 1C and 6C, such embodiments are shown in which a material strip 61 is used as a carrier of the cut protection. The two strips 41 of the cut protection 30 together with the material strip 61 form a group 60.

FIG. 6E shows an embodiment in which two strips of material 61 are used. The two strips 40, 41 of the cut protection 30 together with the strips of material 61 form a group 60.

In embodiments comprising one or more of such strips 61, these strips 61 may be glued or vulcanized to the cut protection 30 (yes, according to material combination). However, the strip (s) 61 may also be e.g. by other stapling compounds, e.g. by attaching a seam 28 (see FIG. 12) to the cut protection 30. REFERENCE NUMBERS:
