EP2404009B1 - Profile connector strip with seal device for sealing joints - Google Patents

Description

The invention relates to a profile connection strip with a sealing device for sealing joints with the features of the preamble of claim 1.

From the DE 10 2004 059 522 A1 a sealing device has become known which has a carrier in the form of a flexible hose which is at least partially coated on the outside with adhesive and can be arranged and glued to the two materials to seal a joint. With a relative movement of these two materials, the hose can flexibly adapt to this movement. Due to its flexibility, however, the hose has no inherent stability.

From the EP 1 992 776 A2 a generic profile connection strip has become known which has a profile body with an outer leg and a component fastening section movably connected to this via two connecting webs formed in particular via coextrusion for fastening the bar to a frame or rail component, in particular a door or window frame or a roller blind rail, via a Has adhesive surface. The connecting webs made of a deformable plastic material are designed to be flexible and extend in a curved manner from the outer leg to the fastening section, so that they can be deformed in a rolling movement when the fastening section is horizontally displaced relative to the outer leg.

From the DE 10 2007 009 945 A1 a plastering strip or profile strip for window frames or doors has become known, which has a base section with web sections for connection to a plaster layer, a frame fastening leg for connection to the window frame and a sealing lip for covering and sealing the joint formed between the window frame and base section. These named components of the profile strip are formed as a structural unit. The frame fastening leg is connected in particular movably to the base section via a convexly curved connection section. A support body is formed as part of the frame mounting leg or it is e.g. B. a soft foam strip, which is connected to the frame attachment leg or the base section via adhesive layers. The support body holds the frame attachment leg in a defined position and thus facilitates the assembly of the profile strip. With relative movements between the profile strip and the frame in the installed state, the support body can z. B. solve from the frame mounting leg and allow this an adjustment movement. The sealing lip can adapt to the relative movement by elastic deformation and continue to seal the joint, whereby it also continues to cover the connection section.

The disadvantage of this plastering strip is that the frame attachment leg, the sealing lip and the support body together with the base section form a solid structural unit and the sealing device formed by the sealing lip is therefore specially designed for this plastering strip and therefore does not represent a universally applicable sealing device that can also be used for other plastering strips would be usable.

The object of the invention is to provide a profile connection strip with a sealing device of the type mentioned above, which has good assembly properties and ensures improved permanent sealing of a joint even with larger relative movements between the profile connection strip and the component in the installed position. The sealing device should provide a stable installation position, at least during its installation or processing.

• die bei der Montage der Profilanschlussleiste an dem Bauteil aufgrund ihrer Tragstabilität die beiden Befestigungsabschnitte zueinander stabilisiert hält und somit die Profilanschlussleiste an dem Bauteil positioniert hält und
• die derart gebildet ist, dass sie Relativbewegungen der beiden Befestigungsabschnitte in Einbaustellung aufgrund von Relativbewegungen zwischen der Profilanschlussleiste und dem Bauteil unter Verformung der eine dichte Abdeckung der Fuge beibehaltenden Dichtvorrichtung bzw. des Hüllkörpers zulässt.

The object is achieved according to the invention in the profile connection strip mentioned at the outset in that the sealing device has a support device in the enveloping body,

• which, when the profile connection strip is mounted on the component, keeps the two fastening sections stabilized with respect to one another due to its supporting stability and thus keeps the profile connection strip positioned on the component and
• which is formed in such a way that it allows relative movements of the two fastening sections in the installed position due to relative movements between the profile connection strip and the component with deformation of the sealing device or the enveloping body that maintains a tight cover of the joint.

Advantageous refinements of the invention are given in the dependent claims.

A component for connection to a sealing device according to the invention is, for example, a profile strip or a part of a building or another structure. A component can be, for example, a door frame, window frame, built-in furniture, roller shutter box, stairs, wash basin, shower cubicle, tile, sheet metal strip, board, beam, masonry, concrete wall, plaster, drywall or window sill. A component can, however, also be a profile connection strip, such as, for example, the known reveal connection profiles or roof ventilation profiles or plaster end profiles. In the case of an expansion joint as the 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. Profile strips can, for example, be embedded in a building surface, as is usual with layers of plaster and layers of filler. However, profile strips can also be arranged on a building surface, as is usual with renovations.

Joints between two components are primarily found in construction. A common joint extends along z. B. a surface of a wall and has a certain depth perpendicular to the surface and a certain width between two components, the width being constant for components arranged in parallel and with non-parallel surfaces of the two components can have different widths over their depth. Joints can, for example, be arranged both vertically and horizontally on vertical parts of a building, with the drainage of moisture at horizontal joints usually being more difficult than at vertical joints. All these joints must be made permanently tight in accordance with the known regulations and requirements.

A design-related and / or weather-related relative movement can occur 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. The sealing device solves the actual technical challenge, namely a permanent sealing of a joint with simultaneous dynamic relative movement.

The support device of the sealing device according to the invention has an elongated shape z. B. in the form of a band or a bar or even just a thin layer and is expediently formed from materials that allow that they can ensure the mutual positioning of the two components in the assembly position. The support device does not necessarily have to be tight in the sense of a seal in every configuration, since the enveloping body according to the invention takes over the essential seal.

A sealing device according to the invention provides both an assembly and a sealing device in a spatially integrated design. The assembly device creates a stable connection between the components and is used to initially position the sealing device during assembly, while the sealing device is used to permanently seal the joint.

A support stability or positionally stable connection for the mutual positioning of two components until the completion of the assembly or processing can become immobile or be able to move. For example, a support device of a sealing device according to the invention can enable a certain relative movement of the components to one another when a force is applied during assembly. After the end of this force, the support device will preferably return to the starting position.

Of course, a positionally stable connection is not understood to mean any connection between any two components. In the building industry relevant to the invention, one component can be stable, solid and heavy and the other component or the profile connection strip is, in contrast, light. A positionally stable connection holds a relatively light component or the profile connector strip to another relatively light component or to a relatively heavy component. A mutual positionally stable connection of two relatively heavy components such as steel girders is not provided by the sealing device.

For the sealing device to function, it is necessary that a certain preferred force ratio is present or established on the components involved or their connections. The assembly forces are smaller than the internal holding force, adhesive force or adhesive force on the support device. These internal forces are in turn smaller than the external holding force, adhesive force or adhesive force between the support device and the respective component. These external forces are in turn preferably smaller than the stretching or tensile forces that can be absorbed by the enveloping body during relative movements. Thus, when a force is exerted by a delivery and assembly force in the delivery state or in the assembly state, this delivery and assembly force is transmitted via a first external connection device or adhesive device and a second external connection device or adhesive device of the sealing device through the holding force that can be absorbed by the support device, without one of the external connection devices dissolves or a material of the enveloping body tears. As a result, the sealing device behaves in a technically advantageous manner with regard to the force flow occurring during relative movements, so that the sealing device provides the desired seal in every sealing position.

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

The main advantage of the sealing device according to the invention is thus the flexible adaptation of the enveloping body to the respective, even large, relative movements or joint movements with a simple, cost-effective and space-saving design. The enveloping body is designed and designed according to the size of the relative movements to be expected. At the same time, a portion of the sealing device that is possibly visible in the installed state can be designed advantageously narrow. During its processing, the sealing device establishes the stable positioning of the two components with respect to one another due to the design that is stable in terms of shape and position.

The sealing arrangement that can be produced using the sealing device is accordingly simple and inexpensive to produce. It also requires little space in the joint.

The appearance or the visual presentation of the sealing device is improved and flawless compared to the state of the art due to the technical solution of the movement absorption.

Due to the two-sided, d. H. inner and outer covering of the joint is permanently sealed. Even if a cover or a cover section of the enveloping body fails, the seal is ensured by the further cover or the further cover section of the enveloping body.

A sealing device according to the invention has a thickness, for example, in the range from 0.5 mm to 20 mm. In the case of reveal connection profiles, a preferred thickness is, for example, approximately 1 mm to 5 mm and in particular approximately 2 mm to 4 mm. For expansion joint profiles for ETICS or wet plaster, a preferred one Thickness for example about 2 mm to 15 mm and in particular about 4 mm to 10 mm.

A sealing device according to the invention has a width, for example in the range from approximately 5 mm to 50 mm. In the case of reveal connection profiles, a preferred width is, for example, approximately 5 mm to 20 mm and in particular approximately 6 mm to 12 mm. In the case of expansion joint profiles for ETICS or wet plaster, a preferred width is, for example, approximately 8 mm to 40 mm and in particular approximately 10 mm to 25 mm.

The enveloping body or a sealing band forming the enveloping body of a sealing device according to the invention has a thickness in the range of, for example, approximately 0.08 mm to 3 mm. In the case of reveal connection profiles, a preferred thickness is, for example, approximately 0.08 mm to 0.8 mm and in particular approximately 0.1 mm to 0.5 mm. In the case of expansion joint profiles for ETICS or wet plaster, a preferred thickness is, for example, about 0.1 mm to 1.5 mm and in particular about 0.15 mm to 1 mm.

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

The enveloping body or a sealing tape is preferably designed in such a way that it does not tear under the loads described and thus provides or maintains the desired seal. The material of the enveloping body or sealing tape is selected according to the requirements with regard to the movements and the sealing properties. The enveloping body or the sealing tape is made, for example, of soft plastic such as soft PVC, TPE, polyethylene or similar materials.

The portions of the profile connection strip or the sealing arrangement can already be wholly or partially assembled in the respective delivery state. But you can also completely or partially before or during assembly, for example in a manufacturing plant for profile strips or components or at the construction site.

It is therefore particularly preferred that, in the installed position, an external fastening or adhesive force on the respective fastening section is greater than the internal supporting force provided by the support device for mutual stabilization of the position of the two fastening sections, in particular a separation of the support device or its at least partial detachment from the enveloping body counteracts.

If the enveloping body thus covers the support device both on the outside of the joint and on the inside of the joint, a double seal is guaranteed with greater security. When installing the sealing device, a front, visible covering of the joint is always guaranteed by the enveloping body.

The enveloping body can, for. B. be formed from at least one sealing tape. However, other designs of the enveloping body are also possible which provide an enveloping body that is closed on the circumference. Several sealing tapes or the like can each be connected to one another at a seam or also in an overlapping manner. This in particular simplifies production.

In a simple design, the support device is at least one adhesive layer or at least one layer-shaped adhesive device. On the other hand, the support device can be formed as a particularly deformable support body, in particular as a foam tape or foam adhesive tape. A foam tape or foam adhesive tape can tear open in its material to adapt to the movements of the components at the joint.

In a preferred embodiment, the support device can be formed at least partially integrally or in one piece with the enveloping body. To the enveloping body or z. B. a sealing tape forming the enveloping body, a support body such. B. molded or foamed a foam tape.

To form the closed enveloping body, the two opposite edge sections of the sealing tape are expediently connected to one another in a sealed manner. If two sealing strips form the enveloping body, the associated edge sections of these two sealing strips can be connected to one another, overlapping in opposite directions or pointing outwards in the same direction. The connection can in principle, for. B. be done by gluing or welding.

The sealing tape is preferably folded in a U-shape between the two fastening sections and, in relation to this folding, is firmly and tightly connected to one another at its two edge sections.

The sealing device or the enveloping body can have two essentially planar, mutually parallel and opposite fastening sections. However, non-parallel arrangements are also possible if a joint to be sealed has a z. B. has wedge-shaped cross-section.

Such a sealing device according to the invention can be rolled up due to its structure and, in the delivery state, is rolled up in rolls or coils in multiple layers, in particular a cover film with a non-adhesive or slightly adhesive surface being arranged between the layers of the sealing device. This type of delivery is particularly simple and inexpensive to manufacture and process.

In a preferred embodiment, at least one section of the sealing device on the visible side or the sealing device as a whole is arranged in a concealed manner. In particular, the sealing device is completely or partially covered by at least one of the components. As a result, the sealing device is correspondingly protected from environmental influences and, in particular, from the weather. The sealing device thus has a longer service life. In addition, this increases the choice of material for the enveloping body or the sealing tape or the external connection device.

In a further preferred embodiment, the sealing device or the enveloping body or the sealing tape has a surface structure in the direction of the support device with elevations and depressions and / or a coating for influencing the internal supporting force, in particular the adhesive force of an adhesive layer or a layered adhesive device.

Thus, for. B. with basically the same adhesive properties or adhesive forces of an adhesive by a coating determines the force transmission at this point and z. B. be reduced. The sealing device can have a coating made, for example, of a fleece or of fibers. The coating then preferably determines the internal adhesive force and thus the transferable forces. Depending on requirements, one or more identical or different coatings can be arranged.

The same or a similar result is achieved by reducing the surface in contact with the adhesive. The surface structure can have elevations or depressions which, for example, correspond to a ribbed or knurled surface. As a result, with basically the same adhesive properties or adhesive forces of an adhesive, the total adhesive force at this point is determined and z. B. reduced. This z. B. certain areas of an adhesive layer or a layered adhesive device with reduced adhesive force or adhesive force can be formed so that the sealing device or the enveloping body or the sealing tape can loosen in this area, while it is in other areas with higher adhesive force or adhesive force remains in close contact.

As a result, the preferred balance of forces can be improved or made available in a defined manner.

An external connection device, in particular an adhesive device, for attaching the sealing device or the fastening sections to the components can be provided on the sealing device and / or on the components.

A component 10, for example a door or window frame (in Fig. 1 shown schematically), is inserted into 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 on the soffit is created by means of a joint filling material 14, e.g. B. a filling foam filled. On the outer side 16 of the component 10 directed towards an outer space 15, a profile connection strip 17 known per se is arranged as a connection to an outer cover 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 fastening base 19 and a front plastering leg 20 and a rear plastering leg 21. The profile connection strip 17 is connected to the outside 16 of the component 10 by means of a sealing device 22 according to the invention.

The sealing device 22 has (see also Fig. 1a ) a hose-like enveloping body 23 extending along the profile connection strip 17 with a support body 24 contained therein. The support body 24, e.g. B. a foam tape or foam adhesive tape with a rectangular cross-section is firmly attached by means of an adhesive device or adhesive layer 25 and 26 to a respective inner surface 27 and 28 of two fastening sections 29 and 30 of the enveloping body 23, respectively. The fastening sections 29 and 30 are the two in the longitudinal direction of the enveloping body 23 strip-like sections of the enveloping body 23 in the area of the opposing outer planar contact or connecting surfaces 31 and 32 of the support body 24. The enveloping body 23 contains between its two fastening sections 29 and 30 each have a cover section 33 and 34, respectively Fig. 1 front or outer cover section 33 covers a front, outer or visible end face 35 of the support body 24 in an approximately U-shape and the rear or inner cover section 34 also covers a rear or inner end face 36 of the support body 24, e.g. B. covered approximately in a U-shape. These positional details relate to an installation position of the sealing device 22 on or in a joint 37 extending between the profile connection strip 17 and the component 10 (see FIG Fig. 1 ), which is filled in and sealed by the sealing device 22, which is attached in a sealing manner.

Before the plaster layer 18 is applied to the wall 11, the profile connection strip 17 is fixed in a stable position by means of the sealing device 22 on the component 10 in its intended position which is to be maintained during plastering. To assemble or fasten the profile connection strip 17 to the component 10 (assembly position according to FIG Fig. 1 and 2 ) the sealing device 22 or the enveloping body 23 is fastened or glued to the fastening base 19 of the profile connection strip 17 and to the outside 16 of the component 10 by means of two adhesive layers 38 and 39. The sealing device 22 is arranged in such a way that the cover section 33 covers the joint 37 on the visible side.

The profile connection strip 17 has, for example, a bracket 40 known per se (see FIG Fig. 2 ), which can be separated from the profile connection strip 17 after plastering at a material weakening 41 and to which a protective film 42 covering the component 10 or the window is glued by means of an adhesive layer 43. The sealing device 22 holds the profile connection strip 17 in a substantially positionally stable position against a deformation force (shown schematically with arrow F ₁ ), which z. B. is generated or can be generated by the dead weight of the profile connection strip 17 and the protective film 42 and in particular also by a wind load against the protective film 42.

When the plaster layer 18 is applied to the wall 11, the front plaster leg 20 serves as a plastering aid for a plastering tool 44 (see FIG Fig. 2 ), which presses against the plaster leg 20 of the profile connection strip 17 with a force F _2. The sealing device 22 holds the profile connection strip 17 in its position _{against this deformation force F 2, which is applied in the usual size.}

After the plaster layer has been applied, the joint 37 is reliably sealed by the enveloping body 23, which forms a joint panel that is, in particular, flush with the outer surface of the front plaster leg 20 of the profile connection strip 17.

The component 10 or the door or window frame and the wall 11 have different expansion or movement behavior due to their different technical properties. At the joint 12 are therefore preferably created by a different expansion behavior z. B. Relative movements of the adjacent components when exposed to heat, cold or moisture. The component 10 or the door or window frame and the wall 11 are therefore movably connected to one another for a certain compensating movement. Due to its elastic properties, the sealing device 22 enables compensatory movements between the component 10 and the profile connection strip 17 or the plaster layer 18 firmly attached to the wall.

If, as shown in Fig. 3 If the component 10 moves against the profile connection strip 17 or the plaster layer 18, the joint 37 is narrowed and the sealing device 22 is compressed, the elastic support body 24 being squeezed and compressed. The two cover sections 33 and 34 of the enveloping body 23 adapt to the squeezing movement and the front cover section 33 also forms a joint panel. The sealing effect of the enveloping body 23 or the sealing device 22 is retained, since the two fastening sections 29 and 30 of the enveloping body 23 do not detach from or from their adhesive fastenings 38 and 39.

If the component 10 is from the starting position of Fig. 1 moved against the wall 11 (see Fig. 4 ), 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 38 and 39, which hold the enveloping body 23 or its fastening sections 29 and 30 on the profile connection strip 17 or the component 10, have a greater holding or adhesive force than the inner adhesive devices 25 and 26 between the enveloping body 23 and the connecting surfaces 31 and 32 of the inner support body 24, so that the adhesive connection tears open at least one of the two inner adhesive devices 25 or 26 (in Fig. 4 the adhesive connections of the two adhesive devices 25 and 26 are shown torn open in a schematic representation). As a result, the fastening section 30 of the enveloping body 23 fastened to the component 10 is displaced parallel to the fastening section 29 fastened to the profile connection strip 17 Fig. 4 and retains the sealing function and its function as a joint cover. Depending on the adhesive forces, the support body 24 will either remain on the profile connection strip 17 or it will be displaced with the component 10. The viewing surface therefore remains uniform.

If the component 10 is from the starting position of Fig. 1 moved away from wall 11 (see Fig. 5 , for example a window frame made of plastic contracts), the sealing device 22 is also stressed by shear forces, since the profile connection strip 17 maintains its position on the plaster layer 18. The two outer adhesive devices 38 and 39, which hold the two fastening sections 29 and 30 on the profile connection strip 17 or the component 10, in turn have a greater holding or adhesive force than the inner adhesive devices 25 and 26 between the two fastening sections 29 and 30 and the inner support body 24, so that the adhesive bond tears open at least one of the two inner adhesive devices 25 and 26 (in Fig. 5 the lower adhesive connection 26 between the support body 24 and the fastening section 30 fastened to the component 10 is shown torn open). While the support body 24 remains stationary relative to the profile connection strip 17, the fastening section 30 fastened to the component 10 is displaced parallel to the fastening section 29 fastened to the profile connection strip 17 and the front cover section 33 of the enveloping body 23 takes for example the in Fig. 5 position shown and retains the sealing function or its function as a joint cover. The joint filling material 14 arranged in the wall joint 12 between the component 10 and the soffit or wall 11 tears during the illustrated movement or displacement of the component 10. The viewing surface or joint panel, however, remains uniform.

If the component 10 is from the starting position of Fig. 1 moved away from the profile connection strip 17 parallel to the wall 11 (see Fig. 6 , to the Fig. 3 opposite movement), the sealing device 22 is subjected to tension perpendicular to the two fastening sections 29 and 30. In the in Fig. 6 The position shown, the front cover section 33 of the enveloping body 23 is almost stretched in relation to the originally bulged position and the reserve for movement caused by bending the non-glued front cover section 33 of the enveloping body 23 is thus largely used up. The front cover section 33 of the enveloping body 23 is essentially free of tensile stresses, not stretched and it forms a joint panel. The rear cover section 34 can also adapt, but this rear cover section 34 is less relevant for the sealing function and can be viewed as an additional safety seal if the front cover section 33 takes over the sealing function.

If the component 10 continues to move in the same direction, it is in the position according to FIG Fig. 7 the non-glued front cover section 33 of the enveloping body 23 is at least somewhat stretched over the joint 37 and its reserve of movement has been used up. Before that, the support body 24 on the upper adhesive device 25 has been detached from the fastening section 29 fastened to the profile connection strip 17. The sealing function of the sealing device 22 for the significantly widened joint 37 is retained. If the enveloping body 23 is elastic and stretchable at least in its front cover section 33 or the rear cover section 34 or detaches from the component 10 in sections, the component 10 can also move further away from the profile connection strip 17, during the The front cover section 33 tightly seals the joint 37 and thus continues to form a joint panel.

The enveloping body 23 in the Figures 1 to 7 Sealing device 22 shown is shown by way of example as a seamless hose. Preferably, however, the sealing device is made from various strip-like, in particular flat, components which are formed into an enveloping body by means of a device, brought together and connected to one another. This ensures fast and inexpensive production.

The sealing device 22 according to a further exemplary embodiment (see the enlarged illustration according to FIG Fig. 8 ) is essentially built up in layers and contains the inner support body 24, z. B. in the form of a foam strip, on the two opposite surfaces 31 and 32 of which a respective fastening section 29 and 30 of the enveloping body 23 is fastened by means of an adhesive device or adhesive layer 25 and 26, respectively. The two fastening sections 29 and 30 are spaced apart strip sections of a sealing tape which forms the enveloping body 23 and which is folded in a U-shape in the area of the front cover section 33 in front of the narrow front face 35 of the support body 24. The two edge sections 45 and 46 of the sealing tape are placed in front of the rear end face 36 of the support body 24 with their inner surfaces against one another and connected to one another, for example glued, e.g. B. by means of an adhesive layer 47. The enveloping body 23 is thus closed.

The sealing device according to the embodiment of Fig. 9 differs from that of the Fig. 8 In the embodiment of the enveloping body 23, which is formed by a sealing tape and is connected on the one hand with an edge portion 48 by means of the adhesive layer 25 to the upper connecting surface 31 of the support body 24, with the cover portion 33 in front of the narrow front end face 35 of the support body 24 U- arches shaped, with the lower fastening portion 30 attached by means of the adhesive layer 26 to the lower connecting surface 32 of the support body 24, with the rear cover portion 34 arches over the narrow rear end face 35 of the support body 24 in a U-shape and with the other Edge section 49 is placed on edge section 48 approximately in overlap with upper connecting surface 31 of support body 24 and is glued to this edge section 48 of the sealing tape by means of adhesive layer 50 and thus forms upper fastening section 29 of enveloping body 23.

In the sealing device according to the embodiment of Fig. 10 the enveloping body 23 is made up of two sealing strips 51 and 52, the upper sealing strip 51 ("upper" as shown in FIG Fig. 10 ) and the lower sealing band 52 is connected to the upper or lower connecting surface 31 and 32 of the support body 24 and the respective edge sections 53 and 54 or 55 and 56 of the sealing bands 51 and 52 are comparable to the embodiment of FIG Fig. 8 are placed with their inner surfaces against each other and glued together, for example, z. B. by means of a respective adhesive layer 57 and 58. The two cover sections 33 and 34 are thus formed from portions of the two sealing strips 51 and 52.

The sealing device according to the embodiment of Fig. 11 shows a modification with a support body 24 or generally a support device in the form of an adhesive layer (shown schematically in dashed lines), which the two fastening sections 29 and 30 of the enveloping body 23 firmly together for assembly and in the sense of the described adaptability with relative movements of the components and thereby the two Fastening sections releasably connects in the installation position. Such a support device can be used for any type of enveloping body 23. The lower adhesive layer 39 is covered with a cover film 59, which is peeled off prior to assembly.

Deviating from this, the enveloping body 23 can also be formed from other sealing tape arrangements which provide a closed and sealing enveloping body 23, the sealing device having the corresponding adaptable cover sections 33 and 34 in connection with the support device or the support body 24.

During installation, the sealing device can, if necessary, be arranged in such a way that each of the two cover sections 33 and 34 is arranged on the outer side of the joint on the visible side and forms the joint cover.

The representations in the figures are exemplary and schematic and, in particular, the thickness of the lines represents the components only schematically and they do not necessarily reflect the exact proportions.
