Description

Description: The invention relates to a cut protection strip and to a method for applying a cut protection strip.

There are areas in and on buildings which need special protection, e.g. to prevent damaging a seal. These include, in particular, corners, edges, joints and transition areas in damp and wet areas.

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 transitional area between a floor covering and a wall covering, with tiles and mosaics (for example in swimming pools) and also in room corners, to name just a few areas.

If subsidence of the grout show, or if the grout should have become unsightly, it is often removed by means of a carpet knife or other sharp object 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. penetrate into a wall.

It has as its object to provide a cut protection strip, which handle well and preferably well wound and thus can be transported. In particular, however, the cut protection function of the cut protection strip should not be affected.

According to the invention, the surface is specially designed for embedding in the liquid material in that the surface is rough and / or porous and / or sanded and / or structured in order to be able to form a permanently firm connection when embedding with the liquid material. In addition, the surface may be rough and / or porous and / or sanded and / or structured in order to be able to form a permanently firm connection during (overlapping) gluing with a sealing membrane.

The cut protection strip may optionally comprise in all embodiments a first (longitudinal) strip, a second (longitudinal) strip and a longitudinal bead, longitudinal groove or a connection region which is parallel to the

Strip length and which is arranged between the first longitudinal strip and the second longitudinal strip. In the following, these constellations are generalized as a transition region.

The transition region may be provided in all embodiments with longitudinal slots, oblong holes or with another form of perforation, which extends parallel to the strip length of the cut protection strip. By this perforation, a desired bending point can be defined, which makes it possible to bend a strip of the cut protection strip out of the plane. This perforation may additionally or alternatively define a desired separation line which, when lowering a floor relative to an adjacent wall, automatically separates a first strip (which is fixedly connected to the wall) from a second strip (eg fixed to the floor) connected).

This optional transitional area (with or without perforation) defines, if present, a bending area or hinged flap of a first longitudinal strip with respect to a second longitudinal strip. The use of the word "transition region" is therefore to be understood as a means of achieving this flexibility or foldability.

A cut protection strip is preferably used as follows: the cut protection strip is provided either in its flat form (eg as a rod product) or in an angled form and then at least partially embedded in the liquid material, or the cut protection strip becomes in a rolled up form provided and unrolled before assembly and then at least partially embedded in the liquid material.

Optionally, the cut protection strip in all embodiments comprise a grid structure as a cut-resistant strip. Particularly suitable is a metal grid structure, a plastic grid structure, a fabric grid structure or a fiber grid structure. In such lattice structures, especially the structure of the strip provides protection against damage or cutting with a sharp object.

By definition, it should be in the lattice structure to a (solid) network, fabric, braid, perforated plate, expanded metal or scrim, which is preferably flexible in the plane. The term "lattice structure" is used here as a generic term for the structures mentioned.

Preferably, the lattice structure is designed so flexible in all embodiments that a length of the lattice structure and / or the cut protection strip can be rolled up.

These grid structures, if present, are suitable for both one-piece and multi-piece (multi-strip) embodiments of the invention.

The lattice structure, if any, in all embodiments includes holes, openings, recesses or meshes, which are preferably smaller than 5 mm.

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

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

Its thickness may typically be between about 0.1 mm and 5 mm in all embodiments.

The cut protection strip can be double-layered or multi-layered in all embodiments.

Due to its flexibility, the cut protection strip can be used in all flat embodiments, e.g. lead around a rounding during installation. Therefore, such a cut protection strip may preferably also be laid around edges and radii of (sanitary) objects or devices. In angled embodiments, cuts may be made in the area of an angled foot strip to provide the cut protection strip e.g. to lay around edges and radii.

At least one longitudinal edge of the cut protection strip may optionally have a different material and / or a different structure in all embodiments than the cut-resistant part of the cut protection strip. 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 and / or because it can be better embedded.

At least one longitudinal edge of the cut protection strip in all embodiments may optionally comprise a nonwoven, fibrous or fabric material to facilitate embedding of the cut protection strip e.g. in a liquid material (e.g., a composite seal).

All embodiments may have an optional transition region, as already mentioned.

The optional transition region may be centered on the cut protection strip (e.g., on a grid structure) in all embodiments. The optional transition region may also be arranged externally in all embodiments, but this always extends parallel to the longitudinal direction of the cut protection strip.

At least one surface of the cut protection strip may optionally be provided in all embodiments with an adhesive to the cut protection strip on a building surface (eg a wall or a floor), an object (bathtub, shower channel, etc.) or another product part (sealing tape , Sealing foil, tub strap, etc.).

If the cut protection strip of the invention is used together with a sealing tape or tub band, then preferably on the room side and / or on the wall side sound insulation strips are used.

Preferably, in all embodiments, a butyl adhesive can be used.

The cut protection strip may in all embodiments optionally be provided with at least one sealing sheet which allows attachment / connection of the cut protection strip to a wall and / or to a floor. In this case, the sealing membrane would be included.

Different grid structures 11 are shown in FIGS. 4A to 4F. These grid structures 11 are suitable both for one-piece / single-strip and for multi-piece / multi-strip embodiments of the invention. All embodiments are preferably metal or plastic grid structures 11. FIG. 4D shows an exemplary perforated plate. In Fig. 4G, there is shown another cut-resistant plastic material 10.2 whose (surface) structure is rough due to the addition or addition of an additive (e.g., corundum). FIG. 4H shows another cut-resistant material 10.2. It can be here for example to be a fibrous material (e.g., Kevlar).

The cut resistance can be achieved or improved in all embodiments by addition / addition of fibers, spheres or granules in the plastic material or in the composite material.

The cut protection strip 10 may optionally include in all embodiments a first longitudinal strip 10.1, a second longitudinal strip 10.2, and a longitudinal bead, longitudinal groove or joint region extending parallel to the strip length Lx, referred to herein as the transition region 14. The transition region 14 is located, for example, between the first longitudinal strip 10.1 and the second longitudinal strip 10.2. A corresponding example of an embodiment with a longitudinal bead or longitudinal groove as the transition region 14 is shown in FIGS. 5A and 5B. Several examples with an adhesive-based transition region 14 are shown in FIGS. 5C-5F.

This cut protection strip 10 consists of the first longitudinal strip 10.1, the second longitudinal strip 10.2 and the longitudinal bead or groove. It can be seen in section along the section line 1-l that, for example, a longitudinal cavity can serve as a longitudinal bead or groove as a transition region 14. The material of the longitudinal bead or groove is here identical to the material of the longitudinal strips 10.1, 10.2. The cut protection strip 10 of FIGS. 5A and 5B is in one piece, but may also be multi-piece / strip.

This optional transition region 14, if present, defines a flexure that allows hinged flaps of a first longitudinal stripe 10.1 with respect to a second longitudinal stripe 10.2. The longitudinal bead or groove, if present, does not necessarily have to represent a cavity when viewed in cross-section, as is the case in FIG. 5B.
