Abstract

The profile pinboard has a foam volume arrangement, which by means of splicing tape is directly or indirectly connected with the pinboard and a construction unit is directly or indirectly connected. The foam volume arrangement (22, 24, 25, 28, 29, 30) has a thickness perpendicularly to the profile pinboard (17) of 5 mm.

Description

The invention relates to a profiled connection strip for a transition from a component to a building wall, wherein the profiled connection strip has a foam strip which is connected directly or indirectly to the profiled connection strip by means of adhesive bonding and can be connected directly or indirectly to the component.

From the DE 103 17 414 A1 a generic profile connection strip has become known with a foam tape having a thickness of usually about 2 mm to a maximum of 4 mm in the undeformed state. With this thickness of the foam tape, the properties of the foam adhesive tape mentioned in this document come into their own.

For the problem of relatively large expansion movements so far no practicable or inexpensive or permanent solution is known.

The object of the invention is to provide a profiled terminal strip of the type mentioned, which is improved in terms of their deformability.

The object is achieved in the above-mentioned profile connection strip according to the invention that a arranged on the profile connection strip foam tape assembly has a thickness perpendicular to the profile terminal strip of at least 5 mm. The foam tape assembly may also have a thickness of, for example, at least 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm or even more, resulting in a high movement absorption is possible.

Previous solutions usually try to achieve the absorption of high movements and at the same time secure sealing by means of complex and costly techniques for profiling or by means of cost-intensive compression belts or belt arrangements. Simple, in cross-section one-piece or standardized foam tapes or foam tapes are inexpensive and easy to work with. However, they are only wider than roll or coil goods as high production. Nevertheless, in order to enable a high movement absorption in the case of a profile connection strip, the thickness of the foam strip arrangement is correspondingly increased for the desired movement absorption. In a one-piece foam tape assembly so that also increases their width. The known foam tape assemblies were previously a maximum of 4 mm thick.

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

In a preferred embodiment, the foam tape assembly is formed from at least two foam strips, which are superimposed tightly connected to each other, in particular glued. By means of several foam tapes or foam tapes can increase the thickness without the width must be increased. This saves costs for the foam tapes or foam adhesive tapes and for the profiled connection strip, as these too can be made narrower. At the same time, the higher thinness of the foam tape assembly increases its mobility and thus the capacity for relative movements.

By different material of the foam tapes and / or different cross-sectional dimensions of the foam tapes within a foam tape assembly has these different properties within the profile connection strip and / or in relation to other profile connection strips. This is particularly important for the properties of the profile connection strip with respect to vapor diffusion, movement absorption, mounting properties and the like.

By a height offset within the foam tape assembly, ie by an L-shaped, T-shaped, double-T-shaped or Z-shaped design of the foam tape assembly, one achieves further advantages. The foam tape assembly can thereby be very soft, for example by means of one or more soft foam tapes and / or have a large thickness of for example 6 mm or 8 mm or 10 mm or 12 mm or 16 mm or even more, whereby a high movement absorption is made possible. At the same time, a region protruding in the widthwise direction may for example be formed very dimensionally stable by means of an adhesive tape or one or more foam tapes with low deformation properties and / or only have a thickness of, for example, 4 mm or 3 mm or 2 mm or 1 mm, whereby this protruding region of the foam tape arrangement as a connecting section between the profiled connection strip and the component provides a desired high stability during assembly and processing. The permanent sealing connection between the profiled connection strip and the component is furthermore provided by the soft and / or high connecting portion of the foam tape arrangement, even if the connection in the above region is released in the course of the service life.

Instead of an immediate attachment of the foam tape or foam adhesive tape to the component or on the profile terminal strip, an intermediate layer between the foam tape and the profile connection strip or between the foam tape and the component can be arranged in the indirect connection. The intermediate layer is for example a part of the profile connection strip such. B. a leg.

When installing components such as windows and doors in building exterior walls of a building arise between the frame provided for attachment of the component and a surface layer of the building one or more joints. The surface layer of the structure is z. As wet plaster on solid masonry or a filler layer on an insulating layer on a wall component or a drywall on Ansetzmörtel on a wall component or a tile with a filler coat on wet plaster or a drywall or sheet metal facing on a wall component. A wall component is solid masonry or other wall construction z. As wood or steel, which fulfills the function of a space-limiting element. This also includes the wall components associated sections of ceilings and floors, if they are provided as a mounting base for the horizontal portions of a component.

In the case of large components, in particular of plastic and aluminum, in dark color design and in components on sun-facing sides of the building due to different expansion behavior of adjacent components arise during the useful life of large relative movements or expansion movements between these components. A 3 mx 3 m large plastic window generates seasonal three-dimensional expansion movements, which may be more than 3 mm or 6 mm, especially in the corner area, given the appropriate color and installation position. However, window bands or glazing are also carried out in the order of 100 m ² and more, so that correspondingly even larger expansion movements can occur.

The joints or mounting joints are so very different and varied in their nature, arrangement, dimension, combination and in the expansion behavior. Nevertheless, these joints must be permanently sealed in accordance with the applicable standards and regulations, namely airtight on the inside of the room, outside rainproof and windproof / airtight on the outside and vapor-impermeable on the inside of the room as the outside of the room.

When installing a component in or on a building wall creates a mounting joint. A substantially central portion of the mounting joint is referred to as a component mounting joint and is located z. B. between the window frame and the building wall or the reveal, for example in the area of screwing the window frame to the building wall. The mutual edge regions of the attachment joint, the z. B. a building interior or a building exterior facing, are referred to as joints. Each joint is located substantially between a portion of the profile connection strip assigned to the component and the portion of the component underneath or opposite thereto and merges into the component fastening joint on the inside or on the building wall side. The foam tape assembly is arranged substantially in the joint between a portion of the profile connection strip assigned to the component and the portion of the component lying underneath or opposite thereto.

Since the profiled connection strip, in particular forms a tight unit together with a surface layer of the building wall and also the component forms a dense body, the gap remains to be sealed area. The foam tape assembly is sealingly connected on the one hand to the profile connection strip and on the other hand with the component.

Such a sealing arrangement has the advantage over all previous approaches that it provides with simple components for all installation situations occurring a seal that remains permanently tight in practice occurring in very large 3-dimensional expansion and / or compression movements. The processing effort and the cost of materials are low. The sealing arrangement according to the invention can be prefabricated both on a component attachable to a building wall as well as on a component already attached to a building wall, in particular a door or window frame part.

Preferably, the profiled connection strip is sealingly connected to the surface layer of the building wall with a profile component designed as a connection device. The profile component designed as a connection device can be completely or partially embedded in the surface layer of the building wall. But the profile connection strip can also, especially during renovation work, on be attached to the surface or the surface layer of the building wall. The profile connection strip can be arranged to the surface or to the surface layer of the building wall and connected by means of an adhesive material with the building wall. The connection device ensures a firm permanent connection between the profiled connection strip and any surface or surface layer of the building wall, wherein the fixed permanent connection can have a certain flexibility. The prerequisite for this mode of operation is that the connection force between the profile connection strip and the surface layer or surface of the building wall is greater than the connection force between the profile connection strip and the component.

The compound is produced in particular by a screw connection or an adhesive bond. The connection device is embedded in the surface layer, for example by means of surface materials such as, in particular, plaster, plaster, attachment mortar, putty and tile adhesive, or adhesively bonded thereto. Adhesive material or sealing compound such as adhesive, in particular hybrid adhesive, acrylate adhesive, polyurethane and butyl rubber or permanently plastic adhesive, in particular silicone, acrylic and PU are suitable for embedding or connection and / or sealing with the building wall. The same applies to adhesive tapes.

The surface of the building wall can basically be any surface, i. H. the surface of the building wall and the surface of the surface layer. Furthermore, it should be emphasized that the surface or the surface layer itself has a sealing function for the building wall.

The surface layer of the structure is z. As wet plaster on solid masonry or a filler layer and / or plaster layer on an insulating layer (ETICS thermal insulation composite system) on a wall component or a drywall, which in turn may have a spatula or a fine plaster on topping on a wall component or a tile with a leveling coat on wet plaster or a drywall or sheet metal facing on a wall component.

Surface layers are usually between 1 mm to 25 mm thick. Insulating plasters usually have thicknesses of up to 80 mm. Fillings on concrete or old plaster or drywall can be 1 mm to 4 mm thick. Fillers and / or plasters in ETICS are preferably 4 mm to 10 mm thick. Wet plaster is usually 10 mm to 25 mm thick. Usual sheet thicknesses range between 0.4 mm and 1.2 mm.

In this case, it is assumed that at least one position of the surface layer suitable for fastening a profile connection strip itself has the standard-compliant properties of wind or airtightness and / or watertightness. The property, according to which the seal inside the room should be more vapor-tight than room outside, is required for solid masonry, in contrast to thermally insulated wood or steel structures, not for the building wall, but especially only for the spatially narrow area of the mounting joint.

It is also assumed that the connection of the profile connection strip with the building wall is intended not only for the duration of installation or for a short period of use, but for the entire duration of use.

To maintain the sealing connection between the profiled connection strip and the building wall, it is important for the connection to be frictional or force-transmitting. Usually, such compounds are rigid or rigid.

The sealing connection of profiled connection strip and building wall is simpler and with increased quality produced when the connection device is arranged on a profile leg or at least partially formed by a profile leg and is designed in particular in the region of its sealing connection with the building wall for intensive connection. This is done for example by recesses or holes, as is usually the case with punches arise. A rough or non-slip surface or a reinforcement fabric section attached to the profile connection strip is also suitable for this purpose.

With the profile connection strip, a foam tape assembly is sealingly connected, which in turn is sealingly connected to a component attached to the building wall. As a result, this foam tape assembly extends over the joint and seals it almost independently of its dimension and arrangement and of any expansion movements occurring. Such a foam tape assembly is universally applicable, standard, simple in construction and inexpensive to manufacture, since it can be produced with known components.

The foam tape assembly is preferably strip-shaped in the longitudinal direction and / or designed to be consistent in cross section.

Preferably, the connection of the foam tape assembly is carried out with the profile connection strip and / or the component by means of adhesive material, wherein the adhesive material is particularly adhesive on both sides. Adhesive surfaces are often provided with a weakly adhering and thus removable protective cover for the delivery and assembly process. This can z. As silicone papers or PE films. For thick adhesive material, a longitudinally elastic protective cover is preferable. This prevents the formation of notches in the adhesive material in rolls or spools. The adhesive material may be an adhesive tape or an adhesive or a permanently plastic adhesive. Adhesive tapes typically consist of a carrier material with a one-sided or double-sided adhesive device and are in particular double-sided adhesive tapes or foam adhesive tapes (SKB). As a carrier material in particular various papers, films, foams and dimensionally stable elastic compositions, eg. As acrylate, EPDM, TPE, PVC, polyurethane, rubber, sponge rubber used. The adhesives include, in particular, hybrid adhesives, acrylate adhesives, PU adhesives, butyl rubbers. The permanently elastic adhesives include, in particular, silicones, acrylics and PU compounds.

The prerequisite for the sealing function of the profile connection strip is that the connection force between the profile connection strip and the surface layer or surface of the building wall is greater than the connection force between the profile connection strip and the component.

The force which can be transmitted by the connection device must in particular be greater than the connection force generated or producible by the foam tape arrangement and, consequently, greater than the adhesive force or breaking force of the bonding material or carrier material of the foam tape arrangement. Thus, the foam tape assembly is preferably a weaker link in the power flow between the component and the building wall. In case of overstressing, the carrier material preferably breaks or fails the at least one adhesive bond of the foam tape arrangement.

The greater connection force of the connection device is preferably produced by means of a larger connection surface and / or stronger or harder material such as, in particular, plaster, spatula, fixing compound and the like.

The advantages of a seal directly on the component are well-known from the siding connection profiles. In this case, usually in one step, the seal can be created without the surface layer already having to be applied. This allows, in particular, a pre-assembly of the sealing arrangement as far as possible already z. B. in the factory of the component. This foam tape assembly makes the seal after assembly, even with large expansion movements. Since the profiled connection strip is more firmly connected to the building surface via the connection device than via the foam strip arrangement with the component, high relative movements merely lead to movements in the foam strip arrangement without tearing or separation taking place. The foam tape assembly can only meet the sealing requirements if it is actually sealingly continuous.

The foam tape assembly performs its task of permanently sealing connection while absorbing relative movements very well when they associated with their wider cross-sectional dimensions of the component or the profiled terminal strip and / or attached thereto, since it forms a wider attachment base particular adhesive base in this way.

Conveniently, the foam tape assembly includes a lateral broadening spaced from its mounting base on the profile connection strip an additional support on the profile connection strip, in particular on a second attachment portion of the profile connection strip offers.

Preferably, in addition to a mounting base on the inside of which the foam tape assembly is fastened or glued, the profile connection strip comprises a second fastening section, which is in particular offset laterally offset relative to the mounting base or the adhesive position of the foam tape assembly and opposite the mounting base in the direction of the thickness of the foam tape assembly, such that the attachment base and the second attachment portion are arranged in different planes.

The sealing compound of the foam tape assembly is or is preferably made by means of an adhesive material. In this case, the adhesive material is particularly adhesive on both sides or a self-adhesive material. Adhesive surfaces are often provided with a weakly adhering and thus removable protective cover for the delivery and assembly process. This can z. As silicone papers or PE films. For thick adhesive material, a longitudinally elastic protective cover is preferable. This prevents the formation of notches in the adhesive material in rolls or spools. The adhesive material may be a sealing adhesive tape or a sealing adhesive or a permanently elastic sealing adhesive. Sealing adhesive tapes typically consist of a carrier material with a one- or two-sided adhesive device and are in particular double-sided mass adhesive tapes or foam adhesive tapes (SKB). As a carrier material in particular foams and elastic compositions, for. As acrylate, EPDM, TPE, PVC, polyurethane, rubber, sponge rubber used. The adhesives include, in particular, hybrid adhesives, acrylate adhesives, PU adhesives, butyl rubbers. To the Adhesives or sealing adhesives, the permanently elastic adhesives or sealing adhesives in particular include silicones, acrylics and PU compositions. The ability to absorb movement, in particular three-dimensional, is a decisive criterion in the choice of material and the dimensioning of the shape.

For the proper functioning of the foam tape assembly, a high permanent adhesive force is of particular importance in bonding. The adhesive force of the foam tape assembly with the profile connection strip and / or the component is preferably greater than the inner expansion force of the foam tape assembly. This adhesive bond is insoluble in the optimal case, so that in case of overuse z. B. the carrier material would be overstretched and would fail as a weaker link of the power chain.

It is advantageous if the profile connection strip is movably connected by means of the foam tape assembly with the component in the installation position for an expansion movement. In continuous use occur, especially due to weather significant relative movements between the component and the building wall. Three-dimensional movements of the respective joint or fixing joint of +/- 0.5 mm to +/- 1.0 mm occur regularly. Expansion movements up to +/- 2.0 mm or even +/- 3.0 mm are rarer in the turn of the year and depend in particular on the component size, the material, the color and the weathering. Relative movements along and / or transverse to the foam tape assembly of +/- 6 mm, +/- 9 mm or even more are unusual, but certainly to be expected. The thickness movement is usually due to the rigid boundary of the building surface such. B. plaster or filler layers on both sides of the component and is from +/- 0.5 mm or +/- 1.0 mm or even +/- 2.0 mm to mostly +/- 3 mm as the upper limit. In order to be able to absorb such movements, the elongation at break value and / or the mobility for a further sealing connection must be correspondingly high.

If the foam tape assembly is arranged wholly or partially in the component mounting joint, it may happen that z. B. in the processing between the unclad building exterior wall and the component and / or an additionally arranged element passes a substantially incompressible material, in particular plaster or putty. So that destructive resistance does not occur in the occurring expansion movements, it is advantageous if the foam tape arrangement is compressible with respect to its thickness. A corresponding profile shape or design and / or a several mm thick, compressible material allows for hard, non-compressible backfill between the building wall and component and / or arranged thereon elements according to the profile forming or thickness and compressibility of the strip of material an expansion of the component or arranged thereon elements such. B. aluminum shells or shutter guide rails.

To compensate for an increased relative movement between the profile connection strip and the component, the foam tape assembly may have increased elasticity and / or increased elongation at break and / or reduced Shore hardness. This is on the EP 1 469 139 A1 which is hereby expressly incorporated into this application.

This allows a sufficiently flexible and at the same time permanently sealed seal can be achieved.

Due to the technical design of the foam tape assembly or the selection of the elastic material standard technical property can be produced. The respective standards (eg DIN 4108), regulations (eg EnEV, RAL guidelines for assembly) and test specifications specify which values are required and must be complied with in order to be assigned to a specific tightness class. The respectively required absorbable expansion movements are known. Since both the profile terminal strip and the component are usually relatively immovable, the respective required property is determined by the foam tape assembly. For a rain-proof and / or a wind-tight or airtight and / or a space inside against the outside of the room vapor-tight seal and / or the ability to absorb stretching movements, a variety of known sealing materials or adhesives are available, which are suitable for the sealing function. The foam tape assembly may comprise one or more single and / or double sided adhesive devices having one or more peelable protective films. The foam tape assembly is, for example, a foam plastic strip, which is particularly adhesive on both sides. It can have different thicknesses or widths and consist of different foams.

Depending on the requirements or arrangement - outside or inside the room - the foam tape arrangement is diffusion-permeable or diffusion-permeable or diffusible or hardly diffusible or conforming to standards (see DIN 4108). For the production of the respective property preferably sealing materials or adhesive materials are used which have a certain μ value (water vapor diffusion resistance number) or S _d value (vapor diffusion resistance) (see for a more detailed explanation of these values EP 1 426 540 A2 ).

Components such. B. windows usually have a rectangular basic shape. If a space inside and / or outside of the surface of the component used for sealing, the seal must also be arranged rectangular. In the case of profile connection strips with attached adhesive sealing devices, the profile connection strip in the corners of the component is butted or a miter is cut for a circumferential seal. This creates an interruption that causes a leak. Such an interruption can be sealed with an already described adhesive material or sealant. In an advantageous embodiment of the invention, the profile connection strip or the foam tape assembly is at least partially disposed in the Bauteilbefestigungsfuge and at least the foam tape assembly separately from the profile connection strip first attached to the building wall side surface of the component. Thus, the sealing arrangement via a junction of two angularly arranged legs of the component without interruption leakproof. In the proposed solution, therefore, the foam tape assembly can be circumferentially mounted in one piece and so produce an increased tightness without additional sealing effort.

The arrangement of the foam tape assembly on the mounting base and / or the material or the formation of the foam tape assembly determine the technical data of the seal assembly and thus compliance with the standards and regulations.

For example, the adhesive material is the same or different. In particular, in the case of multilayer adhesive material, for example, at least one adhesive device and / or at least one carrier material may be the same or different.

An identical or different cross-sectional shape or thickness and / or width of the adhesive material and / or the adhesive device and / or the carrier material offer themselves as a design latitude. Furthermore, the adhesive material, in particular at least one adhesive device and / or at least one carrier material, the foam tape assembly may be wholly or partly continuous or separated from each other.

In order to distinguish its properties or its spatial assignment (space outside or inside space), the sealing arrangement and in particular the foam tape assembly may have a color coding. Here is on the DE 103 14 001 A1 which is hereby expressly incorporated into this application.

A component is, for example, a frame base body (not the wing) of a window or a door or a component such as a beam. Standard wood, aluminum and plastic windows and windows are used. It is often attached to other elements such as an aluminum shell or aluminum paneling in wood or plastic windows or guide rails for roller shutters or mosquito nets, attachment roller shutter box and the like. The invention is suitable for both interior space as well as for space outside joints. By a mutual sealing arrangement creates an overall seal between the component and the building wall. In this case, the inside sealing arrangement and the outside sealing arrangement may contain similar or different foam tape assemblies. These features thus provide, individually or in combination as well as in combination with all the features disclosed in this application with respect to the profiled connection strip and in particular with regard to the connection device and the foam strip arrangement, an overall seal according to the invention.

The profile connection strip is preferably arranged or mounted on an inner or outer side of the component or an additional element of the component and / or the foam tape arrangement is located on a section of the component (rear or peripheral side of the component) facing a component fastening joint or a building wall or on the component toward sealingly arranged additional element of the component, which may also be a further profile connection strip, or is attached thereto.

The invention is also suitable for the joints of elements that are associated with a component and thus directly or indirectly connected to the component, in particular screwed or glued, such as window panels and their boards, aluminum shells or aluminum panels in wood or plastic windows or guide rails for Shutters or mosquito nets, top roller shutter box and the like.

Furthermore, the profile connection strip, in particular the intermediate layer or the foam strip, an optical identifier, in particular a certain color, have, so that the handling in the selection of the correct profile connection strip is facilitated. Thus, confusion of the different profile terminal strips, especially when handling by auxiliary forces, avoided and the sealing of the joints created technically correct.

The profile connection strip is z. B. used on the surface of a wall, for example, the transition of exposed concrete or an existing plaster layer to a window. In this case, the fastening and / or sealing to the surface of the wall towards preferably by means of an already described adhesive material or sealant or the profile terminal strip is embedded in the surface of the wall, such as. As in plaster, thermal insulation composite systems, drywall, tiles, sheet metal and the like.

The profile connection strip is made for example of metal or plastic or other known profile material. Preferably, the profile connection strip or the foam strip is made of plastic. Among the plastics, polyvinyl chloride, polyolefin, polyethylene, polypropylene, polystyrene and polyurethane are particularly preferred. The cross section of the plastic portion of the profile connection strip remains the same over its length, so that the profile connection strip can be produced inexpensively by extrusion.

The profiled connection strip is, for example, in one or more parts and in particular in two parts. The profile connection strip is, for example, a plaster profile, soffit profile, plaster finish profile, drywall profile, end profile, tile profile or filler profile.

At the profile connection strip preferably profile components such as a plaster removal edge, a Einputzschenkel, a peel strip, a soft lip, a ETICS fabric or a mounting base for a protective film, also as a peel strip with adhesive device, are provided.

A component 10, for example a door or window frame (in Fig. 1 shown schematically), is inserted in a wall opening and connected to the wall 11. A gap 12 between the peripheral side 13 of the component 10 and the wall 11 is by means of a Fugenfüllmaterials 14, z. B. a Füllschaumes filled out. On the outer side 15 directed towards the outside 16 of the component 10 is a known profile connection strip 17 as a connection to an applied on the wall 11 outer cover layer, such as a plaster layer 18, respectively. 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. The profile connection strip 17 is made by means of a plastic made and a foam tape assembly performing Foam tape or foam adhesive tape 22 attached to the outside 16 of the component 10, so that the foam adhesive tape 22 forms an intermediate layer between the component 10 and the mounting base 19 of the profile connection strip 17.

When applying the plaster layer 18 on the wall 11 of the front Einputzschenkel 20 serves as Einputzhilfe for a cleaning tool and he specifies the thickness of the plaster layer 18. A gap 23 formed between the profile connection strip 17 and the component 10 is filled or sealed by the foam adhesive tape 22.

The joint 23 thus allows due to the elastic properties of the foam adhesive tape 22 to some extent compensating movements between the component 10 and the profile connection strip 17 and the plaster layer 18, which has a different expansion behavior z. B. when exposed to heat, cold or moisture. When the component 10, for example, a wooden window frame, contracts (see Fig. 1 Moving in the direction of the arrow perpendicularly away from the wall 11), the foam adhesive tape 22, which compared to conventional foam adhesive tapes substantially greater thickness (ie the extension perpendicular to the mounting base 19 of the profile connection strip 17) of at least 5 mm or more, to this Move or adjust this offset elastic without tearing. Due to a larger thickness of z. B. even 10 mm, the foam adhesive tape 22 can perform this elastic deformation movement, even if it has no optimized for the elastic deformation material properties (eg., An increased extensibility). Thus, the foam tape or foam adhesive tape 22 can be made of a simple foam at a low cost. The thickness of the foam adhesive tape 22 is less than its width (in each case according to the cross section Fig. 1 based), which usually ensures a stable attachment of the profile connection strip 17 on the component 10. However, the thickness of the foam adhesive tape 22 could also be greater than its width, so that it has a narrow and slim cross-section for improved movement.

At the in Fig. 2 illustrated embodiment, the foam tape assembly of two foam adhesive tapes 24 and 25 is formed, each of which has a greater width than thickness. In the illustrated foam tape assembly, the two foam adhesive tapes 24 and 25 are arranged one above the other and tightly connected to each other and in particular glued together with an adhesive layer 26. If foam tapes are used, the adhesive layers for mutual connection and connection to the profile terminal strip 17 and the outer side 16 of the component 10 are applied separately, while in adhesive foam tapes with one-sided or two-sided adhesive layer, the bonding hereby takes place.

Since the individual foam tapes or foam adhesive tapes 24 and 25 are not slim, they can be individually wound up into larger rolls or bobbins, as opposed to slender tapes which are not suitable for reeling or spooling, before being joined together to form the foam tape assembly of the present invention.

Basically, the foam tape assembly of Fig. 2 also be supplemented by further foam tapes to an even thicker three- or multi-layer foam tape assembly. The individual foam adhesive tapes 24 and 25 can, as shown, have the same cross sections and the same material properties or they are different with respect to these features. So also different thickness foam tapes 24 and 25 can be connected or glued together.

Fig. 3 shows a modified embodiment of a profile connection strip 27 for use according to the installation situations of Fig. 1 or 2 or modified installation situations. A foam tape arrangement is formed from three foam adhesive tapes 28, 29 and 30 arranged one above the other or bonded together. The upper foam adhesive tape 28 is glued to the mounting base 31 of the profile connection strip 27. The outer or lower foam adhesive tape 30 containing an adhesive layer 32 is made shallower and substantially wider than the two other foam adhesive tapes 28 and 29, thus facing laterally the other foam adhesive tapes 28 and 29 with a lateral spread 35 and is additionally attached to a second attachment portion 33 of the profile connection strip 27 via this widening 35 via an adhesive layer 34. The attachment portion 33 thus serves both to stabilize the foam tape assembly prior to assembly of the profile connection strip 27 to a component 10 as well as a pressing aid when adhering the outer foam adhesive tape 30 via this widening 35 to a component 10th

This foam tape assembly of Fig. 3 Thus, it can have a very slender and thus mobile part, which is formed by the foam adhesive tapes 28 and 29, and yet have good stability before processing. The wide outer or lower foam adhesive tape 30 provides a stable attachment of the foam tape assembly to the component 10.

The two foam adhesive tapes 28 and 29 can be replaced by three or more foam adhesive tapes or even by a foam adhesive tape. Further, the bottom foam adhesive tape 30 may also be an adhesive tape (i.e., without a foam structure) and the foam adhesive tapes 28, 29 and 30 may be the same or different adhesive tapes or foam adhesive tapes or any combination thereof.

A profile connection strip 37 (see Fig. 4 and 5 ), as a modified embodiment for use on a surface of a wall, such. As in renovation work, includes a mounting base 38, on the inside of a first inner foam adhesive tape 39 is attached to a foam tape assembly consisting of the inner foam adhesive tape 39 and a second outer foam adhesive tape 40. The second outer foam adhesive tape 40 is attached or glued to the outer side 16 of the component 10. An inner leg 41 of the profile connection strip 37 which protrudes at right angles from the attachment base 38 extends, for example, approximately beyond the height of the first inner foam adhesive tape 39 in the mounting arrangement of the profile connection strip 37 on the component 10. The profile connection strip 37 is connected to a plaster layer 18 formed by a wall 11, that a gap 42 between the inner leg 41 and the plaster layer 18 with an adhesive material or a sealant 43, z. B. a silicone compound filled. The longer the inner leg 41 is formed, the larger the connecting surface for the sealing compound 43 and thus the bond strength of the connection.

An outer leg 44 of the profile connection strip 37 is arranged approximately parallel to the inner leg 41 and terminates in an inwardly parallel to the mounting base 38 aligned support leg 45. The support leg 45 forms a second mounting portion for the foam tape assembly and on its outer surface 46, which is approximately at height the bonding or adhesive plane between the two foam adhesive tapes 39, 40 and thus arranged offset in relation to the mounting base 38, the outer foam adhesive tape 40 is glued with its above the inner foam adhesive tape 39 projecting widening 47. An at least partially flexible lip 48 is formed on the outer leg 44 such that it applies to the outside 16 of the component 10 under elastic prestressing and thus covers the outer foam adhesive tape 40 lying behind it and protects it against UV radiation and weathering. The shape of the profile connection strip 37 in the region of the outer leg 44 can of the in the Fig. 4 Diverge form shown, as long as a second attachment portion for the foam tape assembly is formed thereon.

When the component 10 is opposite the wall 11 and the plaster layer 18 in a direction according to the arrow 49 (see Fig. 5 ), z. B. due to commonly occurring known relative movements, the connection of the thinner outer foam adhesive tape 40 dissolves from the second attachment portion on the support leg 45, since this compound has a lower adhesive strength as the connection of the outer foam adhesive tape 40 to the component 10 and since the sealant 43 the inner leg 41 and thus the profile terminal strip 37 holds firmly in position. The inner, softer foam adhesive tape 39, because of its greater flexibility and compliance, can follow the movement of the component 10 and deforms accordingly without cracking. The inner foam adhesive tape 39 thus holds a tight connection between the component 10 and the profile terminal strip 37 and thus the plaster layer 18 upright.

Even if the Fugenfüllmaterial 14 is torn due to the movement of the component 10 (as in Fig. 5 is shown as a crack 50), the seal is maintained by the foam tape assembly or the two foam adhesive tapes 39 and 40.

One in the Fig. 6 and 7 shown modified embodiment of a profile connection strip 37 ', z. B. for renovation use, contains a foam tape assembly with two identical, similar or similar foam adhesive tapes 51 and 52 in superimposition. This profile connection strip 37 'is formed without a second attachment portion, but also has a sealing lip 48'. During a movement of the component 10 in the direction of the arrow 49 '(see Fig. 7 ) according to the above embodiment of the Fig. 5 , wherein the Fugenfüllmaterial 14 can also tear, deform the two foam adhesive tapes 51 and 52 in approximately similar and maintain a sealing connection between the component 10 and the profile connection strip 37 'upright. The function of this profile connection strip 37 'corresponds essentially to that of the profile connection strip 37 according to FIGS Fig. 4 and 5 However, the profile terminal strip 37 according to the Fig. 4 and 5 with their wider attachment base, made sturdier by the wider and additionally supported outer foam adhesive tape 40, and easier to handle during assembly.

Also in the two profile terminal strips 37 and 37 ', the foam tape assembly by the opposite Fig. 4 to 7 modified combinations of foam adhesive tapes and / or adhesive tapes or in each case a single foam adhesive tape or adhesive tape to be replaced.
