Description

Sealing device for joint sealing between two components

The invention relates to a sealing device of a joint seal, wherein an elongate support body of the sealing device has two opposing outer surfaces which are provided for connection to two joints to be sealed between forming components by means of external connection means, and a supporting stability for mutual positioning of the two components during assembly.

From DE 10 2007 009 945 A1, a plastering strip or profile strip for window frames of doors or windows has become known, which cut off a base section with a web for connection to a plaster layer, a frame fastening trough! for connection to the frame and a sealing lip for covering and sealing the gap formed between the frame and the base section has. These mentioned components of the profile strip are formed as a structural unit. The frame attachment leg is in particular movably connected to the base section via a convexly bent connection section. A support body is formed as part of the frame attachment leg or he is z. B. a soft foam strip which is connected via adhesive layers with the frame attachment leg or the base portion. The support body holds the frame attachment leg in a defined position and facilitates thus the assembly of the profile strip. In relative movements between the profile strip and the frame in the installed state, the support body z. B. from the frame attachment leg and this allow a fitting movement. The sealing lip can adapt to the elastic movement by elastic deformation and continue to seal the joint, while still covering the connection section.

A disadvantage of this plaster strip, that the frame attachment leg, the sealing lip and the support body together with the base portion form a solid unit and the sealing lip formed by the sealing device is thus formed specifically for this plaster bar and thus does not represent a universally applicable sealing device, which also for Other plaster strips would be usable. Another disadvantage is that this fixed unit is formed by a relatively rigid extruded profile strip. Thus, this profile strip is not rollable or reelable. Another disadvantage is that for each profile variant own costly extrusion tool must be made.

From EP 1 469 139 A1 a sealing device is known, which has a foam tape as a support body, which at its two opposite outer surfaces in each case via an adhesive layer both on a profile strip as well as on a component, for. B. a window or door frame in a building wall, can be fixed. In the case of an excessive relative movement between the profiled strip and the component, the foam strip which is formed with improved properties compared to the prior art for compensating for such an increased reivative movement between the profiled strip and the component can nevertheless no longer be adapted due to a lack of sufficient elasticity tear, so that the gap between the profile strip and the component is no longer sealed. Furthermore, the appearance of this sealing device is in need of improvement.

From EP 1 808 565 A1 a sealing device of a sealing arrangement for a joint has become known, which is formed by a mounting device and by a sealing device, which are arranged one behind the other in the joint and have different properties with regard to their adaptation to relative have movements between a profile strip and a component, which form the joint between them. The mounting device serves for the initial positioning of the profile strip during assembly and the sealing device serves for the permanent sealing of the joint. This sealing arrangement thus requires two separate assembly or sealing devices, which are arranged in the joint one behind the other, and is therefore expensive and requires larger space in the joint. Again, the appearance is in need of improvement.

DE 10 2004 015 556 B4 discloses a plaster connection strip which has a base part, a plastering part and a flexible connecting wall in an integral construction. The base part is fastened to a component by means of a foam adhesive tape. In the case of relative movements between the plaster connection lead and the component in the installed state, the flexible connecting wall deforms according to the re-motive movement and furthermore provides a joint seal. Such a plaster connection strip is designed comparatively expensive and especially in relative movements by the complex and staggered in depth design visually unattractive. The appearance is therefore in dire need of improvement. In addition, a separable material bridge is required for this technique. This can only be produced at an increased cost and restricts the further technical design options in this cleaning connection strip.

The object of the invention is to provide a sealing device of the type mentioned, which ensures a secure and permanent sealing of a joint, even with larger relative movements of the two components in the installation position to provide a profile strip with such a sealing device, which is suitable for improved sealing of a joint is to provide as well as a sealing arrangement with such a sealing device or such a profile strip on a joint with improved properties. In this case, the sealing device should provide a position-stable mounting position at least during their assembly or processing. Furthermore, the sealing device should in particular also provide an improved appearance in the installed state and relative movements ready.

The object is achieved according to the invention in the sealing device mentioned above, that a sealing tape is provided which covers an end face of the support body between its two outer surfaces and maintains a tight joint cover even with a relative movement of the two outer surfaces in the installed position and thereby caused change of the support body the sealing device or the sealing strip and the supporting body are formed independent of component.

The object is also achieved by a profile strip with such a sealing device with the features of claim 14 and by a sealing arrangement with such a sealing device with the features of claim 15.

Advantageous embodiments of the invention are specified in the respective dependent claims.

A component for connection to a sealing device according to the invention, which may also be referred to as a sealing tape unit, is for example a profiled strip or a part of a building or another building. A component can thus be, for example, a door frame, window frame, built-in furniture, roller shutter box, stairs, sink, shower cubicle, tile, sheet metal strip, board, beams, masonry, concrete wall, plaster, drywall or a windowsill. However, a component can also be a profile connection strip, such as, for example, the known reveal connection profiles or roof ventilation profiles or plaster termination profiles. In an expansion joint as a joint to be sealed, for example, two profile strips can form the components and come to rest on the building parts on both sides of the expansion joint. Moldings, for example, be embedded in a building surface, as is common in plaster layers and spatula layers. Moldings can also be arranged on a building surface, as is usual in the renovation. Joints between two components are primarily found in construction. A usual joint extends longitudinally z. B. a surface of a wall and has a certain depth perpendicular to the surface and a certain width between two components, wherein the width is constant in parallel components and may have different widths at non-parallel surfaces of the two components over their depth. Joints can be arranged vertically and horizontally, for example, on vertical parts of buildings, whereby the removal of moisture from horizontal joints is usually more difficult than at vertical joints. All of these joints must be formed according to the known regulations and requirements mostly permanently tight.

The sealing device or the sealing tape preferably seals with respect to one or more in the known standards and regulations, for example, with respect to the ift guideline MO-01/1 (published by the testing institute ift in Rosenheim, Germany), designated requirements. These include, for example, weather influences from wind, rain, light or temperature (cold and heat). Usually, a space-inside joint is vapor-vapor-tight to form as a space-outside joint. A gap in the interior of the room is preferably airtight, and a gap on the outside of the space is preferably to be formed without impact rain. Interior joints are often sealed against the usual influences during use, such as damp in wet rooms. A seal is preferably permanent and not just short-term. The seal is preferably also with regard to the expected mechanical loads, such as cleaning work, sufficiently resilient form.

There may be a design-related and / or weather-related relative movement between the components. Depending on various factors, these relative movements can take place in the three spatial directions and have different values. The relative movement can generate longitudinal movements and / or transverse movements and / or changes in the distance between the two components relative to one another. The sealing device solves the actual technical challenge, namely a permanent sealing of a joint with simultaneous dynamic relative movement. The support body of the sealing device according to the invention has according to the longitudinal extent of a sealed joint an elongated shape z. B. in the form of a band or a bar or even a thin layer and is suitably made of such materials that allow it to ensure the mutual positioning of the two components in the mounting position. The support body does not necessarily have to be tight in any design in the sense of a seal, since the sealing tape according to the invention takes over the essential seal and this preferably exclusively.

The support body has between its two outer surfaces provided for attachment at least one end face and usually according to its shape two opposite end faces. The sealing strip can for a sealing of a joint according to the invention cover each of the two end faces, which may be flat or arched, tight. The front page is z. B. a flat or curved surface or even a narrow strip or is formed in the form of a line depending on the design of the support body.

A relative movement of the two outer surfaces of the support body of a sealing device according to the invention is due to a corresponding relative movement of at least one of the two components, each by means of an external connection device such. B. an adhesive layer or bonding or an integral formation are connected to the support body.

The primary task of the support body is to provide a mounting-stable positioning or a position-stable connection of the components until the completion of the assembly. In a preferred embodiment, it supports and improves the sealing properties of the sealing device.

A sealing device according to the invention provides both a mounting and a sealing device in spatially integrated design. The mounting device establishes a stable connection of the components and The purpose of the initial positioning of the sealing device during assembly, while the sealing device is used for the permanent sealing of the joint.

A supporting stability or stable connection for the mutual positioning of two components until the completion of the assembly or processing can be immobile or movable. For example, a support body of a sealing device according to the invention under force during assembly allow a certain relative movement of the components to each other. After the end of this force, the support body will preferably return to its original position.

Of course, a positionally stable connection does not mean any connection of any two components. In the construction relevant to the invention, one component can be stable, solid and heavy, and the other component can be light, such as, for. B. a profile strip. A positionally stable connection holds a relatively lightweight component, such as a profile strip, on another relatively lightweight component or on a relatively heavy component. A mutual position-stable connection of two relatively heavy components is not provided by the sealing device.

For the function of the sealing device, it is necessary that a certain preferred balance of forces on the components involved or their compounds is present or produced. The assembly forces are smaller than the inner holding force, adhesive force or adhesive force on the support body. These internal forces are again smaller than the external holding force, adhesive force or adhesive force between the

Supporting body and the respective component. These external forces are preferably in turn smaller than the tensile or tensile forces that can be absorbed by the sealing strip during relative movements. Thus, when a force is applied by a delivery and assembly force in the delivery state or in the assembled state, this supply and assembly force is transmitted via a first external connection device and a second external connection device of the sealing device by the holding force that can be absorbed by a carrier body, without any of the external connection devices coming loose or a sealing tape material breaks. This behaves the Sealing device technically advantageous with respect to the force flow occurring during relative movements, so that the sealing device provides the desired seal in each sealing position.

Fasteners or connections or external connections are made for example by adhesive devices. In principle, however, other types of tight fastenings or connections such as vulcanization or welding or clamping are possible.

The main advantage of the sealing device according to the invention is thus the flexible adaptation of the sealing strip to the respective, even large, relative movements or joint movements in a simple, cost-effective and space-saving design and reliable tightness due to the firm connection of the edges of the sealing strip with the components. The sealing strip or the sealing device is designed and designed according to its application and the size of the relative movements to be expected. This does not require a separate, cost-intensive extrusion tool for each profile variant. The various embodiments of the sealing device can, for example, be assembled in a simple manner from suitable components by means of a device. At the same time, the portion of the sealing device that is visible in the installed state can advantageously be made narrow. During its processing, the sealing device establishes the positionally stable positioning of the two components relative to one another by the form-stable and position-stable design.

The sealing device or sealing arrangement according to the invention consists of only one unit and is accordingly easy and inexpensive to produce. It also requires little space in the joint. It is essential that the sealing device or the sealing strip and the support body are formed independent of component. By this is meant that no shares of one of the components or a profile strip are integrated. Thus, the sealing device is also universally applicable. The appearance or the visual presentation of the sealing device is improved and perfect by the technical solution of the movement recording over the prior art. It is particularly preferred that the sealing device or the sealing strip forms a joint aperture in the installed position. Thus, no other element is required for a cover. A joint stop is that part of a joint seal which is visibly arranged and visible in the installed state or in the case of relative movements in the joint. In the stationary installation state or in the different movement positions in the case of relative movements, a joint aperture provides a perfect optical presentation. At the same time, the joint is and remains sealed by the sealing device according to the respective standards.

In a preferred embodiment, the sealing strip and / or the supporting body can be connected to the two components by means of a respective external connecting device. In particular, the external connection device is substantially planar. In particular, the proportion of a component provided for connection to the sealing device is also planar. This simplifies the production of the connection, since flat surfaces are simple, universal, defined and inexpensive, for example, by an adhesive device can be connected.

The sealing band is preferably fastened with its two edges on the support body or connected to it, so that it always covers the associated end face of the support body sealing. If the support body in cross-section z. B. is formed substantially rectangular with two parallel outer surfaces, the two edges of the sealing strip are expediently attached or integrated at the corner regions of the support body or at edge portions of the outer surfaces. Each outer surface of the support body may have adjacent to the end face a recess or depression, so that when applied sealing tape there is a plane or planar top or outer surface on which a component is to be attached.

The sealing tape can also be integrally formed with the support body, for example by coextrusion. A band-shaped material, for example, also one piece essentially form the sealing tape and the support body. For this purpose, it can be produced or reshaped or processed accordingly.

Furthermore, mixed forms of these solutions are possible, so that z. B. the sealing strip is integrally formed at one of its edges with the support body and at the other edge on the support body z. B. is attached by gluing or welding.

The transition from the sealing tape to the support body can be made stepless. The location of the transition can also change or move locally in the case of relative movements in response according to the invention of the sealing device, in particular in the case of large relative movements. The support body defines itself primarily by providing the position-stable connection until completion of the assembly. If this connection subsequently becomes lost due to relative movements, for example, the former supporting body can also function as part of the sealing strip, depending on the technical design of the sealing device.

Conveniently, the sealing tape or a central portion of the sealing strip is at least connected via a peripheral sealing tape strip with the outer surface of the support body or applied thereto. The sealing strip strip can cover a section or strip of the outer surface adjacent to the end face or the entire outer surface. The sealing strip strip can thus pass into the support body. In addition to the outer surface, this sealing strip strip can also form a base for fastening a component or remain without a fixed connection to the component. In the latter case, the sealing strip strip is preferably connected via the support body indirectly sealingly with the components.

The sealing band preferably has such a width between its two edges on the carrier body that it can adapt to relative movements of the components. If the sealing strip is bendable, but not stretchable, its two edges can be as far apart from each other with an expansion of the support body until it is stretched. The sealing tape can be delivered or the Mounting position bulbous or U-shaped to be arched over the front side of the support body so that it can perform a path compensation according to the size of the curvature. It thus has, in particular, a movement reserve due to the possibility of a flexible deformation.

If the sealing band is flexible and, in particular, expansible, it can, if its two edges are excessively removed from each other, adapt to this displacement. Thus, the sealing strip in the delivery state as well as in the installed position both arched as well as just before the front side of the support body be arranged. It thus has in particular a movement reserve by means of deformation by stretching. When stretch occurs in the sealing tape tensile forces.

An adaptation to a relative movement thus takes place, for example, by bending and / or stretching of the sealing strip. In relative movements of the joint limiting components can be made for example in an expansion or compression or longitudinal shear or transverse shear or a mixed form of these relative movements.

A section of the sealing device adjacent to the sealing strip, for example a section of the supporting body, can also be included in an adaptation. The sealing strip can be released continuously or stepwise in sections with excessive relative movement or expansion of a joint from the respective component, wherein, of course, a certain portion of the sealing strip or the sealing device must remain in close contact with the component. This should be taken into account when designing a sealing device. The sealing device must be tight at least in that region or section which extends in the installed position or in the operating state after a relative movement of the components between these components. This is at least the middle section of the sealing strip and, if appropriate, sections of the sealing device which detach from the components. Those areas or sections of the sealing device which always remain attached to the components do not necessarily require such a tightness. In a preferred embodiment, the sealing tape is formed from at least two sealing bands or sealing tape sections, which are connected to each other in front of the end face of the support body and on the other hand mounted respectively on the support body or integrally formed with the support body. The two sealing strip sections are connected tightly in an overlapping connecting region. Alternatively, the two sealing band sections are formed by a single sealing strip which is folded in a U-shape and whose two legs form the two sealing bands and whose band center section can perform a matching movement during a relative movement of the components.

In a preferred embodiment, the sealing device or the support body or the sealing tape is layered, band-shaped, strip-like or block-shaped and / or has a line-like, rectangular, square, triangular, trapezoidal or elliptical cross section. The sealing strip or the two sealing strip strips or the sealing strip sections or the support body or the layers of the support body or outer surfaces of the support body are arranged in the layer-like arrangement - depending on the view or installation position one above the other or side by side - preferably parallel or at least substantially parallel to each other. However, they can not be arranged in parallel, wherein the central connecting device in cross-section z. B. is wedge-shaped. This makes it possible to carry out different designs of the sealing device, which are adapted to a respective installation situation of two components.

The support body or the inner support layer can be, for example, a paper, cardboard, fleece, felt, fabric, fabric, foil or the like. Mixed forms or multi-layer combinations can also provide the desired properties.

In a particularly preferred embodiment, the sealing device or the support body or the inner support layer or the sealing tape is a foam tape or foam adhesive tape or a sealant or adhesive. Such or similar material may be in its thickness for the particular application or to be sealed Fugue be adjusted and adjusted. Due to its thickness, such material can shape the shape and size of the band middle section. Such material is preferably compressible and can therefore be used in compression as well as narrowing joints due to its flexible adaptability. By choosing the material, the respectively transferable force is co-determined and supports the production of the preferred balance of forces, whereby the function of the sealing device is favored.

Preferably, the support body is constructed from a support layer or from at least two support layers, which are connected to each other in particular by means of a central connection device.

Preferably, the support body is at excessive relative movement or relative distance of its outer surfaces between the edges of the Dichtban-, separating between the sealing strip strip or its outer surfaces or solve two support layers of the support body from each other. The holding force of the central connection device is determined by its technical design. If the central connecting device is, for example, a foam adhesive tape, then the holding force is determined by the adhesive force of the adhesive bonds and / or the breaking force of the foam material. The lower force determines the maximum holding force. By this design, the respectively transferable force is co-determined and supports the production of the preferred balance of forces, whereby the function of the sealing device is favored.

Preferably, an outer connection device for fixing the support body and / or the sealing strip or sealing strip strip to a component is respectively provided on the sealing device. In the installed position, an external connection force of the external connection device is greater than an internal connection force of a central connection device or an internal material force counteracting a separation of the support element. Preferably, therefore, the holding force of the two outer connecting devices is set to be larger than the holding force of the central connecting device to the associated components. This ensures that the sealing device will work after processing. processing in relative movements occurring does not detach from one of the two components, but without additional measures the central connecting device gives up their connecting property. As a result, the sealing device always seals the joint even in the case of relatively large relative movements, even if the weaker central connecting device allows the two sealing strips to move away from one another or to disengage from the central connecting device in accordance with the relative movements. The holding force of the external connection devices can be set such that a certain detachment of at least one of the sealing strips from the associated component in the area of the middle section of the sealing strip is possible in order to be able to follow large relative movements, but a sufficient region of the sealing strip is fixed and remains tightly adhered. By this design, the respective transferable force is co-determined and supports the production of the preferred balance of power, whereby the function of the sealing device is favored. In this case, a visible side portion of the sealing strip forms a joint panel. This changes its shape and dimension depending on the relative movement and provides a perfect visual presentation.

The force which can be absorbed by the sealing strip or the sealing strip strip, in particular the stretching force or the tensile force, is preferably set greater than the external connecting force or holding force of the two external connecting devices. As a result, in an adaptation to a large relative movement, the central portion of the sealing strip is in no way destroyed and the seal remains secured. For large relative movements of the band center portion can not only be bent, but also pulled and / or stretched. In most cases, a portion of a sealing band adjacent to the band middle section is then included in an adaptation. This is done, for example, by a certain detachment of at least one of the sealing strips from the associated component in the area of the middle section of the sealing strip, but a sufficient area of the sealing strip remains firmly and tightly glued. By this design, the respectively transferable force is co-determined and supports the production of the preferred balance of forces, whereby the function of the sealing device is favored. Preferably, a central connection device establishes a connection of a plurality of support layers of the support body with one another and / or a connection of one or more support layers of the support body with the sealing strip and / or the sealing strip strip. The central connection device can also be an inner base layer, each with an adhesive device for connecting the inner base layer to the sealing strip or the two sealing strip sections. However, deviating configurations may also be made therefrom, wherein the central connecting device or the supporting body is not limited to the configurations disclosed herein, as long as it fulfills the function according to the invention.

Preferably, the central connection device is an adhesive device. An adhesive device is produced, for example, by an adhesive coating or an adhesive tape or a sealant or adhesive.

An adhesive coating is preferably an adhesive layer to be applied. For example, the adhesive is applied from a container of a suitable device during the manufacture of the sealing device. Adhesives are, for example, hot-melt adhesives or solvent-based adhesives or acrylate adhesives.

An adhesive tape usually provides a ready-to-use adhesive device in a defined dimension. Adhesive tapes are preferably provided as transfer adhesive tapes or foam adhesive tapes. In most cases, these are manufactured as rolls or coils and applied by unwinding on an adhesive substrate.

In an alternative embodiment, the adhesive device of the central connection device may be a sealant or adhesive. A sealant or adhesive is preferably pasty in the production of the adhesive device and binds off after processing. After setting, the sealant or adhesive is often elastic. Household silicone, acrylic, polyurethane or hybrid sealants in cartridges are among the sealants or adhesives. The particular thick layered voluminous mass provides sufficient support for the sealing device or the one component or a profile strip during assembly to another component. In the installed position, the mass can adapt to it during relative movement and in the case of excessively large relative movements, the mass can detach, separate or rupture and thus allow the sealing band to adjust its movement.

Furthermore, a reinforcing layer can be integrated or attached to the sealing strip and / or the sealing strip strip or the sealing strip sections. This reinforcing layer assumes a reinforcing function, so that the sealing strip sections or the sealing strip itself need not be designed for this purpose. The reinforcing function is preferably an increase in the power transmission, for example, when occurring in the sealing band tensile forces.

The external connection device may be an adhesive device and in particular an adhesive coating or an adhesive tape. These are easy and inexpensive to produce. In principle, however, other types of tight fastenings or connections such as vulcanization or welding or clamping are possible.

Preferably, an edge portion of the sealing strip or of the sealing strip strip or of the sealing strip section remote from the band middle section projects beyond the supporting body and / or beyond the outer connecting device and / or beyond the central connecting device.

The sealing device may have a movement reserve, which is formed in particular by at least a portion of the sealing strip, wherein the at least one portion of the sealing strip is preferably arranged with its outer side in the direction of a component and preferably has no external connection means for fixing to a component. As a result, this edge section or the portion of the sealing strip can form a reserve of movement, which can be utilized without great expenditure of force by bending the edge section or the portion of the sealing strip. This will result in an adaptation to a large Reia tivbewegung the central portion of the sealing tape is not stretched or pulled. The adaptation takes place by deformation of the sealing strip, whereby only small forces occur in the sealing strip or only small bending forces are introduced into the sealing device. Preferably, the portion of the sealing tape, which has no external connection device for fixing to a component, removes from the component and thus compensates in a simple manner for the relative movement. Only after this movement reserve has been used up is the band middle section, as already described, also drawn and / or stretched and / or there is a detachment from the associated component during further relative movements. By this design, the respectively transferable force is co-determined and supports the production of the preferred balance of forces, whereby the function of the sealing device is favored. Since in relative movements within the movement reserve no separation of one of the sealing tapes from the associated component takes place, no proportional surfaces of adhesive devices are exposed. Thus, the surface of the edge portion does not tend to be soiled by, for example, accumulation of dust. The appearance or the optical presentation thereby remains impeccable. This improves the function of the sealing device. Such a portion of the sealing strip is preferably arranged parallel to a surface section of a component in the initial installation state.

Expediently, the sealing strip strip and / or the sealing strip contains a surface structure and / or a coating for influencing the transferable force, in particular the adhesive force. Thus, z. B. for basically the same adhesive properties or adhesive forces of an adhesive by a coating, the power transmission determined at this point and z. B. can be reduced. A similar or similar result is achieved by reducing the surface in contact with the adhesive. As a result, with the same adhesive properties or adhesive forces of an adhesive as a whole, the entire adhesive force is determined at this point and z. B. reduced. This can z. B. certain areas of the adhesive devices are formed with reduced adhesive force or adhesive force, so that the sealing device or the sealing band portion or the sealing tape can solve this area, while it other areas with higher bond strength or adhesive force remains in firm connection. The surface structure may have elevations or depressions corresponding, for example, to a ribbed or knurled surface.

If the surface structure has elevations and depressions and the force transmission, in particular the adhesion, takes place substantially at the elevations, the adhesive force in this area is thus reduced.

Mixed forms of the designated designs are possible. By this design, the respectively transferable force is co-determined and supports the production of the preferred balance of forces, whereby the function of the sealing device is favored.

Preferably, a separating aid for separating the supporting body and / or the central connecting device is provided. Such a separation aid can support the separation or release of the central connection device or initiate defined. For example, the sealing device should provide a high holding force as assembly support during processing. After processing, the separation aid is then used to reduce or release the high holding force of the central connection unit. This ensures that the sealing device does not detach from one of the two components after processing when occurring relative movements, but gives up the connecting device without further action, the central connecting device. As a result, the safe operation of the sealing device is ensured or improved.

Expediently, the support body and / or the central connection device has a defined material weakening or a foam strip of the central connection device has a slot or a notch and / or a tearing cord as the respective separating aid. This also ensures that the sealing device does not detach from one of the two components after processing when occurring relative movements, but without further action, the central connecting device their connecting property on gives. As a result, the safe operation of the sealing device is ensured or improved.

In a preferred embodiment, the sealing device in the delivery state is wound in a coil-like multi-layer, wherein in particular a cover film with a non-adherent border or slightly adhering surface between the layers of the sealing device is arranged. This delivery method is particularly simple and inexpensive to manufacture and process.

For a bobbin-like winding, it is expedient if the cover film is mounted either on the outside of the upper outer connection device of the sealing device or the outer side of the lower outer connection device and is in winding contact with the lower outer connection device or the upper outer connection device.

Furthermore, one of the external connection devices, and in particular the upper external connection device, may comprise a foam tape with an outside adhesive device. As a result, an undesired adhesion in a coil-like winding of the sealing device is avoided.

The sealing device can be arranged for example on a profile strip and connected to this. In a preferred application, one of the components is a profile strip or profile connection strip and the other component is a frame, door frame or window frame or a further profile strip or profile connection strip, wherein the component is arranged for example in a wall opening and in particular the at least one profile strip or profile connection strip in the installed state is held by a cover layer of the wall. Here, between the profile strip and the other component, the designated joint is formed, which causes or must absorb relative movements.

According to the invention, a profile strip on a sealing device, which is formed according to one of claims 1 to 14. Preferably, the profile strip in a mounting state, in particular by means of the sealing device on at least one component, in particular a frame, door frame or window frame, fixed in position and takes in the installed state, in particular by means of the sealing device relative movements of the components flexible sealing. As a result, a profiled strip according to the invention also has the described advantages of the sealing device.

Preferably, the profile strip has a profile portion, which covers the sealing device in the installed state completely or partially on the visible side. As a result, the profile strip provides an improved appearance in the installed state and with relative movements. At the same time, the sealing device is better protected against mechanical stress or weathering. In this case, the joint panel formed by the sealing strip is only visible or increasingly visible.

In a preferred embodiment, the sealing device or the sealing band and in particular the visible portion of the sealing strip during relative movements, which represents the joint aperture, formed so that the sealing device and the covering profile portion essentially form a technical functional unit that provides an improved appearance. For example, a portion of the sealing strip during relative movements of the components on the inside of the covering profile portion slide along and avoid a deepened, fissured joints. Due to the properties of the sealing device in interaction with the profiled strip, the degree or the direction of the movement absorption and / or the sealing function is not limited or limited compared with the prior art. The sealing function is ensured with simultaneous three-dimensional recording of large relative movements. The appearance is perfect according to the function of a joint panel.

Preferably, the profile strip is a reveal connection profile or an expansion joint profile and / or at least partially embedded in a plaster or filler layer. A profile strip can be a profile connection strip, such as the known soffit profiles or roof ventilation profiles or plaster finishing profiles. In an expansion joint, for example, two profile strips form the components and come to rest on the building parts on both sides of the expansion joint. Moldings, for example, be embedded in a building surface, as is common in plaster layers and spatula layers. Moldings can also be arranged on a building surface, as is usual in the renovation.

When used as a construction profile, this preferably has one or more of the known features such as Armierungsgewebeabschnitt, Putzabzugskante, sealing lip, peel strip and the like.

In a preferred embodiment, the profile strip in a mounting state on one or more components, preferably by means of the sealing device, fixed in position and the relative movements are flexibly received sealingly in the installed state of the sealing device. This can be carried out, for example, in the case of a one-part or multi-part soffit connection profile or expansion joint profile. In this case, the sealing device, for example, adhesive tapes, which define a central foam plastic tape on the components or on a component and a profile connection strip. The central connecting device, for example, in the form of the adhesive bonded by means of adhesive tapes plastic tape holds the profile terminal strip in the assembled state before plastering and also during the plastering of the component stable in position.

According to the invention, a sealing arrangement is formed with a sealing device and / or a profile strip, wherein the sealing device according to one of claims 1 to 13 and / or the profile strip according to claim 14 is formed.

In a preferred embodiment, the sealing tape or the dense central portion of the sealing strip in the installed state in the joint is arranged on the visible side and forms a joint panel. On the other hand, the sealing tape or the dense central portion of the sealing strip can also be inside the joint and thus hidden and not visible from the outside. The sealing function can be met by both solutions, whereas for a secure weatherproof cover of the central connection device as well as for the visual appearance, the solution is preferred in which the dense band middle section in the joint on the visible side as a joint panel, possibly by a cover such. B. a lip or rib at least partially covered, is arranged.

The sealing device can also be mutually, d. H. have a dense central portion in front of the two end faces of the carrier body. It then preferably has a sealing band in the form of a tubular enveloping body. As a result, a likelihood of confusion is excluded by reversed placement of the sealing device in the joint. The production of the sealing device can be simplified and made cheaper. The sealing device provides the seal on both sides or inside and outside and thus twice. If one of the two seals fails during the service life, the other seal will continue to provide the seal.

Preferably, the enveloping body is formed from at least one sealing tape. Preferably, the two opposing edge portions of the sealing strip are tightly connected to each other to form the closed enveloping body.

In a preferred embodiment, the edge portions of two sealing tapes associated with the closed enveloping body for forming the closed enveloping body are connected to each other in an overlapping or in the same direction outward pointing manner.

In a preferred embodiment, the sealing strip can also be folded in a U-shape between the two fastening sections and be firmly and tightly connected to one another at its two edge sections in relation to this folding.

Preferably, a dense central portion of the sealing strip of the sealing device is arranged on the visible side as a joint panel in the installed state, wherein the sealing arrangement or the profile strip or the sealing device with relative movement or relative removal of the outer surfaces between the edges of the Sealing tape, between the sealing strip strip or its outer surfaces has a visible portion of the sealing device, which is formed as a joint panel uniform and uninterrupted, whereby the appearance is improved.

The visible in the installed state portion of the sealing device is preferably particularly bright or particularly dark. A bright design, especially a white design, results in the usual bright and especially white surfaces of buildings or building components a harmonious complement and thus a preferred appearance with visually perfect presentation. A dark training usually creates the effect of a shadow gap and thus also gives a visually flawless presentation.

In case of Nip joint profiles for EIFS or wet plaster is a preferred thickness, for example about 0.1 mm to 1, 5 mm and in particular about 0.15 mm to 1 mm.

The dimensioning and the material properties of the sealing device are adapted accordingly to the size of the joint and to the size of the expected relative movements.

The sealing tape is preferably designed so that it does not tear at the described loads and thus provides or maintains the desired seal. The material of the sealing tape is selected according to the requirements of the movements and the sealing properties.

Fig. 53 in a cross-sectional view of another embodiment of a sealing device.

A component 10, for example a door or window frame (shown schematically in FIG. 1), is inserted in a wall opening of a wall 11 and connected to the wall 11. A joint 12 between the peripheral side 13 of the component 10 and the wall 11 at the soffit is by means of a Fugenfüllmaterials 14, z. B. a Füllschaumes filled out. On the exterior side 16 of the component 10 directed toward an exterior space 15, a profile connection strip 17 known per se is arranged as a connection to an outer covering layer applied to the wall 11, for example a plaster layer 18. The profile connection strip 17 has an approximately U-shaped cross section with a mounting base 19 and a front Einputzschenkel 20 and a rear Einputzschenkel 21 on. The profile connection strip 17 is connected by means of a sealing device 22, which is also referred to as sealing tape unit, with the outside 16 of the component 10, so that the sealing device 22 forms or contains a support body 29 between the component 10 and the mounting base 19 of the profile connection strip 17. A joint 23 extending between the profile connection strip 17 and the component 10 is thus filled and sealed by the sealing device 22 which is attached in a sealing manner.

Before applying the plaster layer 18 to the wall 11, the profiled connection strip 17 is fixed in a positionally stable manner by means of the sealing device 22 on the component 10 in its intended position to be maintained during plastering. The profiled connection strip 17 has, for example, a tab 24 known per se (see FIG. 2) which can be separated from the profile connection strip 17 after plastering on a material weakening 25 and on which a protective film 26 covering the component 10 or the window is provided by means of an adhesive layer 27 is glued. The sealing device 22 keeps the profile connection strip 17 substantially stable in position in its position against a deformation force (shown schematically by arrow F ₁ ), the z. B. the weight of the profile connection strip 17 and the protective film 26 and in particular by a wind load against the protective film 26 is or can be generated.

When applying the plaster layer 18 on the wall 11 of the front Einputzschenkel 20 serves as Einputzhilfe for a cleaning tool 28 (see Fig. 2), which presses with a force F ₂ against the Einputzschenkel 20 of the profile connection strip 17. The sealing device 22 holds the profile terminal strip 17 against this applied in the usual size deformation force F ₂ in position.

The sealing device 22 according to a first embodiment (see the enlarged view of FIG. 3) has a substantially layered structure and contains as a central layer or inner support layer a foam strip 29, at its two opposite surfaces 30 each have a sealing strip strip 31 by means of an adhesive device 32nd as part of the supporting body is attached. The two sealing strip strips 31 are the spaced edge strips of a sealing strip 33, which is folded in a U-shape and the central portion 34 forms a closed fold or bend as a joint panel in front of a narrow end face 35 of the foam strip 29, wherein the end face 35 according to the installation example of Fig. 1 and 2 is referred to as outer end face 35, since it is directed away from the wall 11 to the outside to the outside space 15.

For mounting or fastening the profile connection strip 17 to the component 10 (assembly position according to FIGS. 1 and 2), the sealing device 22 on the outer surfaces 36 of the two sealing strip strips 31 each have an adhesive device 37 (see FIGS. 1 and 2, not in FIG. 3) shown), by means of which the sealing device 22 is sealingly attached to the profile connection strip 17 and to the component 10. The sealing device 22 is arranged such that the closed center section 34 covers the joint 23 on the visible side. For a secure sealing of the joint 23 is ensured by the sealing strip 33, which forms a joint panel, which is in particular flush with the outer surface of the front Einputzschenkels 20.

The door or window frame and the wall 11 have a different expansion or movement behavior due to their different technical characteristics. At the joint 11 arise therefore preferably by a different expansion behavior z. B. by the action of heat, cold or moisture at the joint 23 movements. Therefore, the door or window frame and the wall 11 are sufficiently movably connected. Due to its elastic properties, the sealing device 22 permits compensation movements between the component 10 and the profile connection strip 17 or the plaster layer 18.

If, as shown in FIG. 20, the component 10 moves against the profile connection strip 17 or the plaster layer 18, the joint 23 is narrowed and the sealing device 22 is compressed, the elastic foam strip 29 being squeezed and compressed. The fold-like central portion 34 of the sealing strip 33 adapts to itself by buckling out of the joint 23 the squeezing movement and continues to form a joint panel. The sealing effect of the sealing strip 33 or the sealing device 22 is maintained, since the two sealing strip strips 31 do not detach from or from their adhesive attachments. The viewing surface is uniform. The appearance or the optical presentation is improved and / or perfect compared with the prior art.

When the component 10 moves from the initial position of FIG. 1 against the wall 11 (see FIG. 21), the sealing device 22 is stressed by shear forces, since the profile connection strip 17 maintains its position on the plaster layer 18. The two outer adhesive devices 37, which hold the two sealing strip strips 31 on the profile connection strip 17 and the component 10, have a greater holding or adhesive force than the inner adhesive means 32 between the two sealing strip strips 31 and the inner foam strip 29, so that the adhesive bond of at least one of the two inner adhesive devices 32 ruptures (in FIG. 21, the adhesive bonds of both adhesive devices 32 are shown in a diagrammatic representation). As a result, the sealing strip strip 31 fastened to the component 10 is displaced parallel to the sealing strip strip 31 fastened to the profile connection strip 17. The folded middle section 34 of the sealing strip 33 assumes, for example, an almost tensioned position according to FIG. 21 and retains the sealing function and its function as joint panel. The foam strip 29 will thus either remain on the profile connection strip 17 as a function of the adhesive forces or it will be displaced with the component 10. The viewing surface or the visible surface is uniform. The appearance or the optical presentation is improved and / or perfect compared with the prior art.

When the component 10 from the initial position of FIG. 1 moves away from the wall 11 (see Fig. 22, for example, a plastic window frame contracts), the sealing device 22 is also claimed by shear forces, since the profile connection strip 17 their position on the Clay layer 18 maintains. The two outer adhesive devices 37, which hold the two sealing strip strips 31 on the profile connection strip 17 or the component 10, have Again, a greater holding or adhesive force than the inner adhesive means 32 between the two sealing tape strips 31 and the inner foam strip 29, so that the adhesive bond tears at least one of the two inner adhesive means 32 (in Fig. 22, the adhesive bond 32 between see the foam strip 29 and the attached to the component 10 sealing strip 31 shown torn). While the foam strip 29 remains stationary relative to the profile connection strip 17, the component is displaced

10 fastened sealing strip strip 31 parallel to the attached to the profile connection strip 17 sealing strip 31 and the central portion 34 of the sealing strip 33 takes, for example, the position shown in Fig. 22 and retains the sealing function or its function as a joint panel. The joint filling material 14 arranged in the wall joint 12 between the component 10 and the soffit or wall 11 ruptures here. The viewing surface or the visible surface is uniform. The appearance or the optical presentation is improved and / or perfect compared with the prior art.

When the component 10 from the initial position of FIG. 1 parallel to the wall

11 moves away from the profile connection strip 17 (see FIG. 23, the movement opposite to FIG. 20), the sealing device 22 is subjected to tension perpendicular to the sealing strip strip 31. In the position shown in FIG. 23, the middle section 34 of the sealing strip 33 is almost taut with respect to the originally bagged position, and the reserve of movement due to bending of the non-glued center section 34 of the sealing strip 33 is thus largely used up. The central portion 34 of the sealing strip 33 is substantially free of tensile stresses, not stretched and forms a joint panel.

If the component 10 continues to move in the same direction, in the position according to FIG. 24 the non-glued center section 34 of the sealing strip 33 is at least slightly tensioned over the joint 23 and its reserve of movement is used up. Previously, the foam strip 29 on the adhesive device 32 has detached from the sealing strip strip 31 fastened to the profile connection strip 17. The sealing function of the sealing device 22 for the significantly enlarged joint 23 is retained. When the sealing strip 33 at least in its central portion 34th is elastic and stretchable or detached from a component in sections, the component 10 can move away from the profile connection strip 17 even further, while the central portion 34, the joint 23 closes tight and thus forms a joint aperture. The viewing surface is uniform. The appearance or the optical presentation is improved and / or perfect compared to the prior art.

With a displacement of the component 10 according to FIG. 24, the sealing device 22 can also react in such a way that (see FIG. 25) the foam strip 29 or supporting body tears flat between the two sealing strip strips 31, since the adhesive forces of the two adhesive devices 32 are greater Preferably, the adhesive forces of the adhesive devices 37 are greater than the adhesive forces of the adhesive devices 32 and / or greater than the material strength of the foam strip 29. If the central portion 34 of the sealing strip 33 is not elastic, the tensioned central portion 34 at a correspondingly large extension of the joint 23 cause a slight detachment of at least one of the two sealing tape strip 31 from the component 10 and / or from the profile connection strip 17 and thereby form a joint aperture. For this purpose, it is necessary for the tensile forces which can be transmitted by the middle section 34 to be greater than the adhesive forces at the point of release of a sealing tape strip 31 or supporting body. The seal of the joint 23 but remains hereby. Basically, a sealing device 22 with a suitable central portion 34 is selected according to the requirements for the possible widening of the joint 23. The viewing surface is uniform. The optical presentation is improved and / or perfect compared to the prior art.

FIG. 26 shows an opening of the joint 23 which is even wider than that of FIG. 25 on further movement of the component 10 away from the profile connection strip 17. The sealing device 22 reacts in such a way that the tensioned middle section 34 pulls off the two sealing strip strips 31 from the component 10 and the profile connection strip 17 against the adhesive force of the two adhesive devices 37 to a certain length and thus forms a considerably widened joint aperture. The sealing device 22 is tuned to a maximum extension path of the joint 23, so that the seal of the joint 23 is maintained. The viewing surface is uniform. The visual presentation is improved over the prior art and / or impeccable.

In a superimposed movement of the component 10 parallel to the wall 11 away from the profiled connection strip 17 and perpendicularly away from the wall 11, the sealing device 22 can assume a position according to FIG. 27. The foam strip 29 has detached itself from the fastener tape strip 31 fastened to the component 10 at the adhesive device 32 and remains on the sealing strip strip 31 fastened to the profile connection strip 17. The middle section 34 of the sealing strip 33 is tensioned and has adhered to the adhesive device 37 on the component 10 solved by about half the width of the associated sealing strip strip 31. Again, the seal of the enlarged joint 23 is maintained and it is formed a visually appealing joint aperture. The viewing surface is uniform. The visual presentation is improved over the prior art and / or impeccable.

According to a further modified exemplary embodiment (see FIG. 4), the sealing device 22 contains two sealing strip strips 31, which in contrast to the example of FIG. 3 are not formed integrally with one another, but overlap in a respective edge section 38 and in the overlapping region by means of an adhesive bond 39 are firmly and tightly connected. Thus, a central portion 34 of the sealing strip 33 formed in this embodiment of two individual sealing tape strips 31 as a closed fold or bulge is formed in front of the lateral end face 35 of the foam strip 29. The movement behavior of this sealing device 22 corresponds to the embodiment described above.

The two sealing strip strips 31 may project beyond the foam strip 29 on the inner end face 40 of the foam strip 29 opposite the outer end face 35. The outer adhesive devices 37 are not shown. These can, for example, only when processing the Sealing device 22 are applied. A sealing device 22 can also be made entirely or partially only at the installation site.

For producing a sealing device 22, for example (see FIG. 5), a sealing tape 33 provided on one side with an adhesive coating 32 can be used, from which a protective film (not shown) covering the adhesive coating 32 is removed before it is folded in a V-shape. A foam strip 29 or other carrier body is brought between the two legs or sealing strip strip 31, which are then pressed against the foam strip 29 and glued to this by means of the adhesives 32 formed by the adhesive coating.

In the embodiment of the sealing device 22 shown in FIG. 6, the two sealing strip strips 31 projecting from the front side are firmly and tightly connected to one another in their edge sections 38, the inner sides of the two sealing strip strips 31 being connected to one another in contrast to FIG. The compound 39 may, for example by means of an adhesive device or by welding the two sealing strip strips 31 z. B. by heating or by adding welding material. The width of the protrusion of the sealing strip strips 31 beyond the foam strip 29 as well as the width of their bonding with the adhesive device 32 can be selected with regard to the required length of the central portion 34 of the sealing strip 33 to be formed.

In the embodiment of the sealing device 22 shown in FIG. 7, the adhesive-free middle section 34 is formed comparatively long and contains a large amount of movement reserve. The two outer adhesive devices 37 extend beyond the foam strip 29 and are thus longer and wider than the inner adhesive devices 32. With the same adhesive material or the same adhesive properties, the outer adhesive devices 37 have a greater adhesive force than the inner adhesive devices 32, so that upon movement the sealing device 22 in the joint 23 will always solve the inner adhesive means 32 and the outer adhesive means 37, the bonding of the sealing strip strips 31 maintained. The adhesive properties can also be be different (see schematic diagram). The bottom according to FIG. 7 adhesive device 37 is provided with a cover 41, z. As a masking paper, covered, so that the sealing device 22 can be wound or wound up while their individual layers do not stick together. The masking paper 41 is preferably adhered and particularly siliconized on its two sides to a different degree and accordingly provided with different adhesivities or adhesive forces such that the unrolling or unwinding of the sealing device releases the masking paper 41 from the next underlying layer, while it applies its covering position the outer adhesive device 37 maintains.

The sealing device 22 according to FIG. 8 has components dimensioned differently from those of FIG. 7. The sealing strip strip 31 of the sealing strip 33 as well as the foam strip 29 are formed thicker and they can be a reinforcing layer 42 such. Example, a glass silk fabric, which is also referred to as a scrim and serves as an inner layer for a tensile force transmission at the central portion 34 when the sealing device 22 is deformed during a movement in the joint 23.

A covering film 41 of the lower outer adhesive device 37 has a free edge section 43 projecting beyond the adhesive device 37 in the region of the central section 34, which is also referred to as a finger lift and serves for easier gripping of the covering film 41 when it is to be peeled off. The movement reserve here is formed comparatively small, so that the overall shape of the sealing device 22 is given a more edged shape in the illustrated cross-section with a more planar arrangement of the middle section 34. This improves the visual appearance, especially in the installed state.

The sealing device 22 according to FIG. 9 contains a U-shaped folded thick sealing band 33 with an intermediate layer 44 as a central connecting device in the form of a thick adhesive layer instead of a foam strip. This sealing device 22 is almost non-compressible. The middle section 34 has a small reserve of movement. The adhesive force of the outer adhesive directions 37 is large ßer than that of the inner adhesive layer, so that it will solve in the deformation of the sealing device 22 according to FIGS. 21 to 27, the connection between the two sealing strip strip 31.

The sealing device 22 according to FIG. 10 contains a U-shaped, thinner sealing tape 33, which has a coating 45, for example made of a fleece or of fibers, on the insides of its two sealing strip strips 31. An intermediate layer 44 as a central connecting device, for example in the form of a strongly adhesive layer, connects the two sealing strip strips 31 in the region of the two coatings 45. The coatings 45 determine the adhesive force and thus the transferable forces. As a result, the ratio of forces can be set very secure. The outer adhesive devices 37 are longer than the inner central adhesive layer 44 and, on the other hand, have a lower, equal or higher adhesive force under otherwise identical conditions. Decisive here, however, is the ratio to the adhesive force by the coatings 45. By the coatings 45, the outer adhesive force is secured higher than the inner adhesive force. Depending on the requirement, one or more identical or different coatings 45 may be arranged.

The sealing device 22 according to FIG. 11 contains a U-shaped folded sealing strip 33 with two sealing strip strips 31, between which an intermediate layer 44 as a central connecting device in the form of a voluminous pasty sealing or adhesive 46, z. B. acrylic, silicone or PU adhesive, is arranged, which is adhesively bonded to the two sealing strip 31. The initially pasty mass binds after some time and hardens product-specific and thus gives the sealing device 22 in the mounting position sufficient deformation stability, so that a profile connection strip 17 is held in position before and during plastering. The mass 46 is compressible according to the design and choice of material over a certain distance when a deformation due to movement of the component of FIG. 20 occurs.

In a shearing motion, the mass 46 can adapt flexibly and elastically to the two sealing tape strips 31 which are removed from one another. Should After a longer installation time, the mass 46 further harden, for example, the mass 46 can tear off one of the two sealing strip strips 31, while the outer adhesive devices 37 (not shown) hold the sealing strip strips 31 firmly on the component 10 or the profile connection strip 17.

The sealing device 22 according to FIG. 12 contains a U-shaped folded sealing strip 33, the two sealing strip strips 31 are connected via a respective adhesive device 32 with a foam strip 29 as an inner support layer. The sealing strip 33 contains on its inner surface a surface structure 47 with elevations and depressions, so that the adhesive devices 32 with the sealing strip stiffeners 31 essentially only have adhesive contact over the elevations. Thus, the adhesive force due to the smaller adhesive surface is lower compared to a full-surface bonding. Preferably, the adhesive force of the adhesive device 32 is less than the adhesive force of the outer adhesive device 37 (not shown) for bonding the sealing strip 31 with the component 10 or the profile terminal strip 17. The elevations and depressions of the surface structure 47, for example in the form of a knurled structure or be formed as adjacent wave-shaped elevations and depressions.

The sealing device 22 according to FIG. 13 contains a U-shaped folded sealing strip 33, whose two sealing strip strips 31 are connected to the foam strip 29 via a respective adhesive device 32. The foam strip 29 has a notch or slot 48 which extends inwardly parallel to its surfaces 30 from the one narrow end face 40 of the foam strip 29 and weakens the foam material such that upon deformation of the sealing device 22 according to the invention the foam strip 29 starts from the slot 48 ruptures as a predetermined breaking point and is separated flat into two parts (see Fig. 25). The two parts 29a and 29b of the foam strip 29 remained connected to the sealing strip 31 via the respective adhesive device 32. The slot 48 can also be provided on the opposite (according to FIG. 13 left) end face 35 and it can also in the two end faces 35, 40 each have a slot 48 or generally a weakening or separation aid 49 may be formed. The sealing device 22 according to FIG. 14 in turn contains a U-shaped folded sealing strip 33, whose two sealing strip strips 31 are connected to the foam strip 29 via a respective adhesive device 32. For a deliberate weakening of an adhesive device 32 or a separation of the sealing strip 31 from the foam strip 29, a tearing strip 49 is provided, which is inserted, for example, when gluing the sealing strip 31 between the sealing strip 31 and the foam strip 29 on the adhesive device 32 and protruding laterally protrudes. For example, in FIG. 14, three tear cords 49 are shown only schematically and by way of example in different installation positions. If the upper tear-off cord 49 is pulled away to the right after installation of a profile connection strip 17 and the adhesive bond of the adhesive device 32 is interrupted in a right-hand separation region 50, this adhesive device 32 is weakened, so that in the case of a deformation of the sealing device 22 according to the invention the entire adhesive bond this adhesive device 32 is preferably separated.

The lower middle tear line 49 separates when stripping to the right on a larger separation area 51. The left tearing cord 49 is incorporated in the foam strip 29 such that it tears apart the foam strip 29 at least partially or even completely in two halves or layers when tearing.

Fig. 15 shows a wound up to a coil 52 sealing device 22. The sealing device 22, depending on the coil size z. B. be wound in a length of 500 m to 4000 m. A cross section through the coil layers is shown by way of example in FIG. 16. The sealing device 22, the z. B. is formed as shown in FIG. 3, contains a U-shaped folded sealing strip 33, the two sealing strip strips 31 are connected via a respective adhesive device 32 with the foam strip 29. In addition, an adhesive device is provided at the top of the upper sealing tape strip 31, which contains a thin foam adhesive tape 53 and the top side is covered with a cover 54. Due to its thickness, this adhesive device provides the spacing which is necessary so that the U-shaped middle section 34 of the sealing strip 33 does not interfere with the uncovered lower edge. means 37 can bond the overlying layer of the sealing device 22 (see double arrow).

The cover 54 contains on both sides surfaces with different bond strength, the z. B. is achieved by different siliconization of the surfaces. When unwinding the sealing device 22 from the spool, the lower adhesive device 37 is removed from the cover film 54 of the next underlying layer of the sealing device 22, on which it rests in an adhesive manner, and is ready to be glued to a component. The cover film 54 must not detach from the adhesive device on the upper sealing strip strip 31 here.

Fig. 17 shows a sealing device 22, as z. As shown in Fig. 10, in its installed position in a joint 23 between two components 10 a and 10 b. The two sealing strip strips 31 are connected on the one hand via a respective adhesive device 32 with the foam strip 29 and on the other hand via a respective adhesive device 37 with the component 10a and 10b. The middle section 34 of the sealing strip 33 is arranged on the visible side and passes almost directly into the two bonded sealing strip strips 31 on both sides, so that there is little reserve of movement before at least one of the sealing strip strips 31 is released by a certain length from its component 10a or 10b. In this case, an adhesive device may be, for example, a sealant or adhesive. This is particularly advantageous when a component has a mineral surface (e.g., plaster, paint, or the like). The surface of the component can also have unevenness and / or a floury, sandy or dusty surface. Such surfaces are usually poorly suited for bonding with conventional adhesive tapes or foam adhesive tapes. For example, a structural adhesive (e.g., polyurethane adhesive) or a hybrid sealant can produce a sufficiently intense compound here.

Fig. 18 shows a known profile connection strip 17 with a sealing device 22, as z. B. in Fig. 9, in the delivery state. A cover strip 41, which covers the lower adhesive device 37, is removed on a component 10 prior to assembly or bonding of the profile connection strip 17. In the month Day and installation state covers the U-shaped central portion 34 of the sealing strip 33, the joint 23 optically perfect.

19, a sealing lip 22 for covering a joint, the sealing device 22 is glued such that the closed central portion 34 of the sealing strip 33 on the opposite side of the visible Behind or inside of the inner end face 40 of the foam strip 29 is arranged. After assembly, the joint 23 is thus sealed within or behind the sealing device 22 and the foam strip 29. Since the sealing device 22 is visibly covered by the lip 55 at its open and optically lower-value end face 35, this arrangement can be selected.

In principle, each sealing device 22 can be arranged in the installed state such that the middle section 34 of the sealing strip 33 lies inwardly with respect to the joint 23 and is therefore optically invisible. In this position, a secure seal of the joint 23 is ensured.

Fig. 28 shows z. B. in a horizontal cross-section, a sealing device 22 in a full thermal insulation of a thermal insulation composite system (ETICS) in which on a wall 11 an insulating layer 56 is applied, extending over the joint 12 between the component 10 and the soffit or the wall 11 and an edge of the component 10 extends. A profiled connection strip 17 has a rectangular cross-section with a component fastening leg 57 and a plaster leg 58 protruding at right angles upwards, to which a reinforcement fabric strip 59 is attached. An integrally formed rigid cover leg 60 of the profiled connection strip 17 covers the sealing device 22 in the installed state in which a plaster or filler layer 61 is applied to the insulating layer 56 and fixes the profile connection strip 17 and the reinforcing fabric strip 59, which forms a sealing flexible connection Profilanschlussleiste 17 provides on the component 10 and seals the joint 23 in the manner already described. The cover leg 60 thus covers the sealing device 22 in Essentially off. The visible part of the joint 23 or the sealing device 22 may be formed, for example, as a shadow gap. For this purpose, at least the central portion 34 of the sealing strip 33 should preferably be formed dark or black. Particularly in the case of relative movements, the middle section 34 forms an optically appealing joint stop.

Fig. 29 shows the application of a profile connection strip 17 in a renovation. A component 10 such. B. a window frame is fixed to a wall 11, wherein a gap 12 between the component 10 and the wall 11 is filled with Fugenfüllmaterial 14. Above the joint 12 is still an old plaster layer 62 on the wall 11 is present, which was limited in the region of the joint 12 by the previously located there old window frame. Since the component 10 is retrofitted during renovation, the thickness of the plaster layer 62 must be taken into account when determining the size of the window frame 10, so that a comparatively wide joint 12 is formed. The profile connection strip 17 is an angle profile with a component attachment leg 57 and a fixing leg 63. The profile connection strip 17 is fixed to the component 10 by means of a sealing device 22 via the component attachment leg 57 and sealed thereto. A joint 64 between the fixing leg 63 and the plaster layer 62 is provided with an adhesive sealing material 65 or a sealing or adhesive material such. As acrylic or silicone filled, which cures or cures product-specific after application and creates a substantially solid connection, so that when relative movements between the component 10 and the wall 11 and the plaster layer 62, the profile connection strip 17 on the wall 11 in Is substantially or completely immobile and the motion compensation preferably via the sealing device 22 takes place. Therefore, the adhesive forces of the inner adhesive device 32 to the sealing device 22 (see eg Fig. 8) must not be greater than the adhesive forces of the adhesive sealing material 65 to the plaster layer 62.

FIG. 30 shows, in a horizontal cross-section, a sealing device 22 in a vertical joint, as shown, for example, in FIG. B. between the thermal barrier coatings 56 on the outer walls of two adjacent houses or semi-detached houses is present. This sealing device or profile strip is also suitable for horizontal joints suitable. The sealing device 22 is arranged in the joint 23 between two profiled strips 17 of a expansion joint profile and each tightly secured by an external adhesive device 37 to a mounting base 19 of the associated profile strip 17. Each profile strip 17 contains a plaster leg 58, which extends at right angles from the attachment base 19 and can have recesses 66 for plaster or filler material 61, which can be applied to the thermal barrier coating 56 and to the profile strip 17 placed on the corner of the thermal barrier coating 17 when plastering the profile strip 17 is applied. A reinforcing fabric strip 59, which is anchored in the putty material 61, is further attached to the plastering leg 58. The mounting base 19 protrudes to the wall outside beyond the Einputzschenkel 58 and serves on its front side 67 when plastering as a trigger edge for a cleaning tool. In the plastered installation state thus the end faces 67 of the mounting bases 19 of the two profile strips 17 are flush with the surface 68 or outside of the spatula or Einputzmaterials 61, the z. B. contains a topcoat.

In the assembled state before installation thus holds the sealing device 22, the two mounting bases 19 of the profile strips 17 parallel to each other in the for installation in the joint 23, the z. B. may have a width of 6 to 10 mm, correct distance. The central portion 34 of the sealing device 22 is located approximately in a plane between the two end faces 67 of the mounting bases 19 and forms a joint aperture. A peelable protective film 69 may be glued to the end faces 67 of the mounting bases 19, which is peeled off after the plastering of the profile strips 17.

The adhesive force of the outer adhesive device 37 is set larger than the adhesive force of the inner adhesive device 32, so that upon relative movement of the two profile strips 17, for example, the support body or foam strip 29 of one of the two sealing tape strips 31 will solve, while the sealing strip strip 31 at least in a sealing portion remain stuck to a remaining portion of the mounting base 19 and thus ensure the tightness of the joint seal. FIG. 31 shows the sealing of an expansion joint 23 in an inner corner at two heat-insulating layers 56 arranged at right angles to one another and spaced apart from one another. In principle, the joint seal corresponds to the exemplary embodiment of FIG. 30, but the left-hand profile strip according to FIG Modified 17 to the effect that the Einputzschenkel 58 is formed as a planar extension of the mounting base 19 and a short plaster removal strip 70 projects at right angles from the mounting base 19 and the Einputzschenkel 58. The middle section 34 of the sealing strip 33 adjoins the plaster removal strip 70 in the installed state, so that a gap-free and thus optically appealing joint seal and joint aperture is created.

In the exemplary embodiment illustrated in FIG. 32, a joint 23 is formed between a roller-blind rail 71 which is attached to the outside 16 of a window frame 10 and a profiled connection strip 17 which is attached to an insulating layer 56 of an EIFS by means of a plaster or putty layer 61 , The sealing device 22 is located in the joint 23 and is fixedly connected by means of the two sealing strip strips 31 and associated external adhesive devices 37 on the one hand with the mounting base 19 of the profile connection strip 17 and on the other hand with a base part 72 of the roller blind rail 71. The sealing device 22 is positioned such that the central portion 34 of the sealing strip 33 is approximately equal in height to an outer leg 73 of the roller blind rail 71 and adjacent to a Einputzschenkel 58, which protrudes from the mounting base 19 approximately at right angles. A strip-shaped tab 24 is integrally formed on the Einputzschenkel 58 via a weakening zone 25, extends over the outer leg 73 of the roller blind rail 71 and is supported by means of a support rib 74 on the leg 73 from. A protective film 26 is attached by means of an adhesive layer 27 on the tab 24, spans the entire window or the frame 10 during plastering and is removed after brushing together with the tab 24 which is separated at the weakening zone 25.

The roller blind rail 71 is arranged on the sealing device 22 relative to the profile connection strip 17 such that the surface 75 of its base portion 72 of the top 76 of the plaster leg 58 and the surface 68 of the plaster or Spatula layer 61 is spaced when the roller blind rail 71 z. B. in a required repair of a belt of the blinds of the window frame 10 is pivoted away (in Fig. 32 of the component 10 vertically upwards past the Einputzschenkel 58). In this case, the seal with the sealing device 22 can be partially or completely destroyed. In a subsequent installation of the roller blind rail 71 in its initial position, a required, subsequent sealing z. B. by a Kompriband or by applying a silicone strip to the space between the roller blind rail 71 and the Einputzschenkel 58 are made.

33 shows a modification of the embodiment of FIG. 32, wherein the profile connection strip 17 has a mounting base 19 and a Einputzschenkel 58 set back relative to the mounting base 19 and preferably parallel to this. The surface of the mounting base 19 is coplanar with the surface 68 of the plaster or filler layer 61 in the installed position. After the tab 24 has been removed, the middle section 34 of the sealing strip 33 sealingly arranged in the joint 23 covers the joint 23 approximately parallel to the surface outer leg 73 of the roller blind rail 71 and offers a perfect appearance. The base part 72 of the roller-blind rail 71 has a greater distance from the surface 68 of the plaster or filler layer 61, the distance corresponding to the gap 23 in which the sealing device 22 is arranged in a sealing manner.

If the roller-blind rail 71 is pivoted away or moved away from the component 10 by a limited distance as shown in FIG. 32, the middle section 34 of the sealing strip 33 can follow this movement without destroying the sealing device 22, given a sufficiently large reserve of movement. This movement reserve exists z. B. in the case when the central portion 34 as shown in FIG. 33 in a wide range is not glued to the RoIIo rail 71 and the profile connection strip 17. If the roller-blind rail 71 is removed over a distance exceeding the movement reserve, the middle section 34 can first be released from its adhesive bond, so that the sealing device 22 also returns to its original position after installation of the roller-blind rail 71 Position remains functional. In addition, the sealing device 22 according to the embodiment of FIG. 32 is destroyed and preferably subsequently sealed again. In any case, a shifting or pivoting the roller blind rail 71 is possible.

FIG. 34 shows an exemplary embodiment in which a sealing device 22 is arranged between a window frame 10 and a profile connection strip 17, which has a U-shaped cross-section and accommodates a drywall 77 which is mounted on a building surface or wall 11. The profile connection strip 17 is fastened to the wall 11 by means of an adhesive or filler layer 78. The sealing device 22, which in principle corresponds to the embodiments described above, is glued approximately half on the window frame 10 and with the other half without adhesive bonding with a component or in conjunction with the Fugenfüllmaterial 14th

In the embodiment of FIG. 35, a sealing device 22 is fixed with its central portion 34 of the sealing strip 33 in alignment between the component 10 and a front Einputzschenkel 20 a profile connection strip 17, wherein the surface 68 of adjoining the profile connection strip 17 plaster layer 62 also in this plane runs. Again, there is an advantageous appearance with only minor interruption of the surface and thus visually perfectly formed joint aperture. This solution is also suitable, for example, for sealing joints in façade flush components such as windows or doors.

FIGS. 36a and 36b show an exemplary embodiment of a sealing device 22 in its sealing arrangement between a component 10 and a profile connection strip 17, FIG. 36a showing the sealing device 22 after installation or plastering of the profile connection strip 17. The outer adhesive devices 37 hold the sealing strip strips 31 firmly to the component 10 or the plaster connection strip 17 and leave the central portion 34 a greater movement or deformation reserve. The distance between the profile connection strip 17 and the component 10 and thus the joint width of the joint 23 is z. B. 4 mm and the Width of the adhesive layer of the outer adhesive device 37 is z. B. 7.5 mm at a width of the mounting base 19 of the profile terminal block 17 of z. B. 10 mm. The central portion 34 is thus not bonded on both sides in a tack-free area 79 of about 2.5 mm and thus free for a movement adjustment and deformation to form a joint aperture.

FIG. 36 b shows the sealing device 22 away from the profile connection strip 17 after a relative movement of the component 10. The support body or foam strip 29 is torn open and the middle section 34 has adapted to the expanded joint 23 with a modified shape of a joint stop by its unbonded portions resting against the component 10 or the profile connection strip 17 have lifted. However, the sealing strip strips 31 are still firmly glued over the adhesive means 37. Since the middle section 34 is slightly arched, there is still a slight movement or deformation reserve for a further slight widening of the joint 23. In a widening of the joint 23 that extends beyond the position shown in FIG. 36b, the middle section 34 and 16 initially stretches Subsequently, the tensioned central portion 34 will release the sealing strip strips 31 from their bonding to the outer adhesive device 37 corresponding to the expansion of the joint 23, if the tensile force transmitted by the central section 34 is greater than the adhesive force of the outer adhesive devices 37.

Fig. 37 shows in the views 37.1 to 37.24 different configurations of moldings 17 in cross section. A profile strip 17 may have one or more plaster removal edges. A profiled strip may have perforations or punched-out areas or a reinforcement fabric section. A profile strip can be narrow or medium or wide. A profile strip may have a connection device for plaster, spatula, tiles, sheet metal, adhesive or the like. A profile strip can be in one piece or in several parts. On a profile strip, a sealing device 22 can be arranged visible or hidden. A sealing device 22 may be narrow or wide, thick or thin, transversely stretched or raised, rectangular or square in cross-section in relation to a profile strip 17. Fig. 38 shows various adhesive devices and their solubility in a basic representation for explaining the adhesive behavior (without sealing device). Fig. 38a shows an adhesive device 80 such. As an adhesive tape or an adhesive coating in the installed state between two components 10 'and 10 "Fig. 38b and Fig. 38c show the two components 10 and 10' of Fig. 38a, after they have moved away from each other. 38b, the adhesive device 80 has completely detached from one of the components In Fig. 38c, the adhesive device 80 has split.

Fig. 38d shows a sealant or adhesive 81 in the installed state between two components 10 'and 10 ". Fig. 38e and Fig. 38f show the state after the two components 10' and 10" have moved away from each other. In Fig. 38e, the adhesive 81 has completely detached from the one component 10 '. In Fig. 38f, the adhesive 81 has been divided.

Fig. 38g shows a foam adhesive tape 82 with two adhesive devices 83 in the installed state between two components 10 'and 10 ". Fig. 38h and Fig. 38i show the position of the components 10' and 10" of Fig. 38g after they have moved away from each other , In Fig. 38h, an adhesive device 83 has completely detached from the one component 10 '. In Fig. 38i, the carrier material, here for example the foam strip 82, divided, while both adhesive device 83 remain in adhesive connection. The carrier material may, for example, also be a paper, cardboard, fleece, felt, fabric, fabric, foil or the like. Mixed forms or multi-layer combinations can also provide the desired properties.

The adhesive devices can also be arranged in mixed form.

An adhesive coating is preferably an adhesive layer to be applied. For example, the adhesive is applied from a container of a suitable device during the manufacture of the sealing device. Adhesives are, for example, hot-melt adhesives or solvent-based adhesives or acrylate adhesives. An adhesive tape usually provides a ready-to-use adhesive device in a defined dimension. Adhesive tapes are preferably provided as transfer adhesive tapes or foam adhesive tapes. In most cases, these are manufactured as rolls or coils and applied by unwinding on an adhesive substrate.

A sealant or adhesive is usually pasty in the production of the adhesive device and binds off after processing. After setting, the sealant or adhesive is often elastic. Household silicone, acrylic, polyurethane or hybrid sealants in cartridges are among the sealants or adhesives.

39 shows a plurality of cross-sectional views of various embodiments of pull-off strips or tabs 24. A schematically illustrated profile strip 17 with a sealing device 22 according to the invention can, in a preferred embodiment, have a known pull-off strip 24.

According to a further embodiment, a sealing device 22 (see FIG. 40) comprises a foam tape as the support body 29, which has adhesive means 37 on its two outer surfaces or surfaces 30 to be attached to components. A sealing tape 33 is bent approximately in a U-shape and covers at a distance the end face 35 of the foam tape 29. The two edge sealing tape strips 31 preferably extend only over a portion of the outer or surface 30 and are sealed in this section with the adhesive device 37 bonded. The attachment or bonding of the sealing device 22 with the respective component is thus effected via the adhesive tape 37 not covered by the adhesive device 37. In addition, a portion of the sealing tape strip 31 are glued to a component.

The sealing device 22 according to FIG. 41 contains two foam strips, foam strips or foam adhesive tapes 29, which are connected to one another via a comparatively thick connection or adhesive device 44. The sealing strip 33 is connected with its middle section 34 with respect to the embodiment. game of Fig. 40 closer to the end face 35 and has in this arrangement and design a lower reserve of movement, but a more edgy shape. A separation of the support body 29 in the installed position in the case of a foot extension can preferably take place at the central connection or adhesive device 44.

The sealing device 22 shown in FIG. 42 includes a support body 29 with a separating aid 49 in the form of a weakening zone on which the support body 29 can tear if necessary, and on the two outer surfaces 30 each have an outer adhesive device 37. The support body 29 is z. As an extruded plastic material or foam material, in which a plurality of slot-shaped cavities 84 are formed in a median plane, between which material webs 85, the two layers or halves of the support body 29 with each other releasably connect. The sealing strip 33 is glued with its sealing strip strips 31 on a larger portion of the outer surfaces 30 of the support body 29.

The sealing device 22 shown in Fig. 43 as a further embodiment includes a support body 29, the z. B. of extruded soft plastic, silicone foam or the like, and a separating aid 49 in the form of an off-center attenuation zone in particular with molded slot-shaped cavities 84 has. The sealing strip 33 is integrally formed and the same material with the support body 29. The sealing strip 33 may be formed with a certain inherent stability and in front of the end face 35, for example, rectangular in cross-section, so that its flat central portion 34 can cover a joint between two components planar and with optically advantageous appearance as a joint panel. The transition 86 of the sealing strip 33 to the support body 29 is formed with increasing thickness in order to improve the stability and the arrangement of the sealing strip 33. A deformation of the sealing strip 33 at Fugenweiterung is still possible to the extent described, since it can be formed stretchable and flexible. On the two outer surfaces 30 29 adhesive devices 37 may be applied in the region of the support body. The cross-section of this sealing device 22 can, for example, in Leibbe- connection profiles or in expansion joint profiles for ETICS preferably in the range of about 8 times 4 mm to 20 times 10 mm.

The sealing device 22 illustrated in FIG. 44, which is designed for slimmer joints compared to that of FIG. 43, likewise contains a support body 29, which is preferably made of an extruded soft material and on which the sealing strip 33 is integrally formed. The sealing strip 33 has a central portion 34 which is formed thicker compared to the sealing strip strip 31 so that it z. B. may contain a greater proportion of plasticizers, whereby it maintains the required flexibility or durability of the plastic material over a longer period of use. This increases the weather resistance. A separation aid 49 is formed as a weakening zone in the center of the support body 29 by a plurality of cavities 84. The adhesive device 37 may be formed on each of the two outer surfaces 30 with different thickness, whereby different adhesive forces on or along the two outer surfaces 30 can be achieved even with otherwise identical adhesive materials. In particular, the sealing strip strips 31 can thus have a lower adhesive force relative to the support body 29.

The sealing device 22 shown in Fig. 45 includes an inner support layer 87 of the support body 29 made of a foam tape or foam tape. An extruded sealing strip 33 has a substantially U-shaped middle section 34 made of soft plastic material and coextruded sealing strip strips 31, which form part of the supporting body 29. The sealing strip strips 31 are made of hard plastic material and fixed by means of the adhesive devices 32 on the outer surfaces 30 of the inner support layer 87 of the support body 29. The sealing strip 33 is glued at its two transitional portions 88 to the sealing strip strip 31 and partially to the inner support layer 87, whereby the softer sealing strip 33 is held in shape.

According to a further embodiment (see FIG. 46), the sealing device 22 is formed from a sealing band 33 which is extruded from soft plastic material in a U-shape and whose two limbs via an adhesive device as central connection device are connected to each other. The central portion 34 has at its end face a greater thickness for greater resistance or a greater proportion of plasticizers. The two adjoining leg sections are made thinner for better mobility and deformability. The subsequent sealing strip strips 31 are in turn formed thicker and, although made of soft material, the stable support body 29. An end portion 89 of each sealing strip 31 is made of hard material coextruded, whereby the support body 29 receives a greater stability here. The two sealing tape strips 31 connecting adhesive bond consists z. Example, from an applied by a nozzle during extrusion adhesive coating, the surface or as shown by a plurality of spaced-apart adhesive areas 90 with z. B. three adhesive beads is formed. The from the sealing tape

33 covered end face 35 of the support body 29 is formed in this embodiment of the inner shoulders of the two sealing strip 31. The adhesive device 37 on the upper outer surface 30 according to FIG. 46 leaves a wider section relative to the lower outer surface 30 to the middle section

34 of the sealing tape 33 toward adhesive-free, so that with built-sealing device 22 at a widening of the joint, the sealing strip 33 initially predominantly on its upper side from its investment in the associated component dissolves before one of the two outer adhesive bonds 37 is partially separated.

The sealing device 22 according to the exemplary embodiment of FIG. 47 contains a support body 29 which is formed from two spaced-apart edge sections of a foam strip which are placed against one another during folding of the foam strip and are connected to one another by means of a central connecting device 44, for example an adhesive device. The central central portion 34 of the sealing strip 33 is z. B. compressed mechanically or by the action of heat and receives over the uncompressed foam material a higher strength, whereas the comparatively thick edge portions are very compressible when the joint narrows during operation. The foam material is z. As a PU foam, a polyolefin foam or a silicone foam. The thickening transition region from the central portion 34 of the sealing strip 33 to the support body 29 is not glued to a component, so that the easy mobility the middle section 34 is maintained. The sealing strip 33 or its middle section 34 may have a coating which can improve the sealing properties or the appearance of the sealing strip 33.

The sealing device according to the embodiment of FIG. 48 differs from the sealing device of FIG. 47 in a comparable manufacturing manner essentially by the changed design and the changed dimensions. The adapting to movements sealing tape 33 is comparatively thin and formed less stable deformation. Therefore, the two outer adhesive means 37 extend very far forward to the sealing strip 33 in order to stabilize it on the components. The two layers of the support body 29 may for example be welded by heat or they are connected by an adhesive device 44 and can tear at this connection again. The two outer adhesive devices 37 can be formed for bonding to different component surfaces with different adhesiveness.

The sealing device 22 according to FIG. 49 is preferably extruded from plastic material. The two layers of the support body 29 are z. B. connected by a weld or heating and fusing the material together. The integrally formed adjustable sealing strip 33 is formed by the end face 35 of the support body 29 projecting very far and thus has a high reserve of movement. To improve the stability of the sealing strip 33, the adhesive means 37 on the outer surfaces 30 of the support body 29 extend very far forward to the central portion 34, wherein in the front adhesive region, the adhesive force is lower (shown by thinner lines).

When compared with the embodiment of FIG. 49 modified in design and dimensions embodiment of FIG. 50, the sealing strip 33 increases continuously at its transition to the support body 29 in its thickness and thus has a higher stability. The two adhesive devices 37 thus do not have to reach the deformation region of the sealing strip 33. The two Layers of the support body 29 are by means of a non-full-surface connection device 44 z. B. connected by bonding together.

FIG. 51 shows a sealing device 22 in a mounted position in a cross-sectionally wedge-shaped or triangular joint 23 between two components 10. The sealing device 22 is e.g. B. constructed according to FIG. 11 and can adapt to the desired wedge-shaped shape of the joint 23 between the two components 10 due to the flexible material of the support body 29 and the inner support layer. The visible portion of the sealing strip 33 of the sealing device 22 on the left side is very low in the installed state, as a result of which the appearance is perfect.

52 shows a further sealing device 22 likewise in an installed position in a cross-sectionally wedge-shaped or trapezoidal joint 23. The sealing device 22 is fundamentally constructed comparable to that of FIG. 43, but is in the illustrated wedge-shaped configuration with non-parallel outer surfaces 30 extruded. The outer adhesive means 37 connect the support body 29 with the two components 10. In addition, the sealing strip 33 is glued to its adjacent to the lower component portion, so that in an extension of the joint 23, the first adjacent to the upper part 10 portion of the relative movement follows. The sealing device 22 has a separating aid 49.

Fig. 53 shows a sealing device 22 similar to the embodiment of Fig. 45, but the U-shaped sealing strip 33 with its two sealing strip strips 31 which are attached or glued as part of the support body 29 on the outer surfaces of the inner support layer, extruded in one piece from hard plastic , The protruding over the end face 35 of the support body 29 portion of the sealing strip 33 includes two hinges 91 or film hinges at the transitions to the bonded sealing strip 31 and two hinges 92 or hinges at the transitions between the central portion 34 to the lateral sections. These joints 91 and 92 allow the relatively stiff sealing band 33 a movement adaptation, in particular in the joints 91 and 92nd The individual features disclosed in the description and with reference to the embodiments and the figures can be combined in any technically expedient arrangements and designs with the subject invention in its most general forms.
