Description

The invention relates to a one-piece sealing or plaster molding for placement at a transition between a component of a building and a thermal insulation or a plaster layer, such a transition with such a one-piece Abdicht- or plaster molding and a method for attaching a one-piece sealing or plaster molding on a such transition.

In the prior art plaster strips are known, which are glued along the edge of a window or door sash to the window or door frame. Such a plaster strip is from the WO 93/17204 known. In this case, a foil is glued to the protective flap of such a plaster strip, which spans the window or door surface within the plaster strips. In this way, the relevant window or door frame is perfectly protected against contamination by sprayed plaster. The plaster ends on the material of the plaster molding, and such a connection can be permanently sealed in conventional window or door frames, because by means of an elastic adhesive tape is a permanent bonding of the plaster strip to the window or door frame.

Modern window or door frames are now often provided with a nano-coating on their surface. Such a nano-coating has nanoparticles, and due to the surface structure of such a nano-coating adheres to the window and door frames little dirt, the window or door frames must be cleaned so much less common than conventional window or door frames. However, this is accompanied by the problem that often show detachments in the known in the prior art plaster strips, and moisture or water enters the space between the window or door frame and insulation. This leads to mold growth and increased heating costs.

It is therefore an object of the present invention to provide a sealing or plastering strip and a transition between a component of a building and a thermal insulation or a plaster layer with which a reliable and durable sealing effect is also given in building components whose surface no permanent bonding allows. It is also an easy-to-carry method for attaching such a sealing or plaster molding to be given at such a transition.

These objects are achieved by the subject matter of the independent claims. Advantageous developments emerge from the dependent claims.

A one-piece sealing or plastering strip according to the invention, which is to be attached to a transition, in particular in a gap of such a transition between a component of a building and a thermal insulation or a plaster layer, comprises a base region, which at its back along the sealing or grout extending expansion strip with delayed expansion for sealing contact of the sealing or plastering strip on the building component and at least one adjacently arranged fastening means for at least temporary attachment of the sealing or plaster strip on the building component. The expansion strip is held in a compressed state by a holding means, and has such a stretchable reserve that it expands after releasing the holding means to a maximum expansion position farther away from the back of the base region than the expansion bar Bottom of the fastener, so as to ensure a sealing contact with the building component even with an increased distance between the building component and the thermal insulation or the plaster layer. At least a part of the front of the base area is intended for contact with the thermal insulation or the plaster layer.

It is possible to arrange the strip according to the invention only in the transition between the building component and the thermal insulation or the plaster layer, without attaching them by plastering or plastering on the insulation. Such a strip is referred to below as a sealing strip. If the strip according to the invention is additionally plastered on or plastered on the thermal insulation, then it is spoken of plastering strip.

When reference is made below to building components, they include all standard building components that can normally rest against thermal insulation, in particular window or door frames, beams, escaping beams, window sills, metal connections or pilaster strips.

Both the thermal insulation and the plaster layer can adjoin the building component on the outside of the building. Alternatively, both the thermal insulation and the plaster layer may be disposed on the inside of the building.

According to one of the invention underlying knowledge changes over time, the distance between the building component and the thermal insulation or the plaster layer by temperature fluctuations occurring, and this effect is particularly pronounced when the transition is exposed to direct sunlight. With an increase in the distance between the building component and the thermal insulation or the plaster layer often solves the fastener, in particular the tape, of the building component, this effect is particularly pronounced when the building component has a surface on a permanent bonding is not possible, for example a nanoparticle surface or a conventional polyethylene surface, polypropylene surface and / or silicided surface.

Due to a basic idea of the present invention can be provided by the inventive provision of an expansion strip for sealing contact the sealing or plaster molding on the building component, which has a Dehnreserve, and at least one adjacently arranged fastening means for at least temporary attachment of the sealing or plastering strip on the Building component a permanent sealing of the transition between the building component and the thermal insulation or the plaster layer are guaranteed, even if temperature-related changes in distance between the building component and the thermal insulation or the plaster layer occur, and even if the building component has a surface, on which only a temporary adhesion, but not a permanent bonding is possible.

In the case of the sealing or plastering strip according to the invention, it is sufficient if the fastening means is only temporarily adhered to the building component during installation of the sealing or plastering strip and, if plastered, plastering, and this is secured by means of the fastening means according to the invention possible. The fastener must ensure only a temporary fixation of the sealing or plaster molding during assembly and during plastering. In short, this can be referred to as mounting stop. For the sealing function, the fastening means is basically not needed.

The fastening means may extend along the sealing or plastering strip and be formed continuously. Likewise, a punctiform or interrupted formation of the fastener is possible.

After installation of the sealing or plastering strip and, if plastered, the plastering the expansion strip takes over the sealing effect by expanding due to the dissolved prior to mounting the sealing or plaster molding holding means and sealingly applies to the building component, but without to take this a liability or bonding. Since this expansion strip has an expansion reserve, this change in distance between the building component and the thermal insulation or the plaster layer can "join in", i. with an increase in the distance between the building component and the thermal insulation or plaster layer and the expansion strip continues to expand, so that it continues to seal against the building component, and with a reduction in the distance between the building component and the Thermal insulation or the plaster layer of the expansion strip is again pressed together a piece, and he continues to lie sealingly on the building component. The sealing effect provided by the expansion strip is sufficient to permanently prevent ingress of moisture or water into the space between the building component and thermal insulation or plaster layer.

The expansion reserve of the expansion strip should be dimensioned so that the expansion strip expands further than corresponds to the maximum width of the gap or the joint, and that the expansion strip is nevertheless impact rainproof in such an expansion. The expansion change of the expansion strip from the compressed state to the maximum impact-proof Ausdehnposition is advantageously at least 25%, but can also be significantly higher in order to join larger gap or joint expansions.

The expansion strip is attached to the base area of the sealing or plastering strip on the sealing or plaster molding side. This attachment can be done in any way, for example by gluing or by a clamp.

The expansion band or expansion strip can be an expanding foam adhesive tape. By selecting the expansion strip, in particular by selecting the expansion reserve of the expansion strip, the maximum expansion position of the expansion strip is determined, ie the maximum distance between building component and thermal insulation or plaster layer, to which a secure seal is ensured. In practice, always provide an expansion strip with a sufficient expansion reserve, which is also able to seal in practice the maximum resulting distance between the building component and thermal insulation or plaster layer and can absorb all movements.

Due to the one-piece design of the sealing or plaster molding, a particularly cost-effective production and easy attachment of the sealing or plastering strip on the construction site is possible.

According to a first embodiment of the invention, the holding means is designed as a cover strip or as a closure flap. This allows a particularly simple release of the retaining means before attaching the sealing or plastering strip at the transition between building component and thermal insulation or plaster layer.

According to a further embodiment, the fastening means is designed as an adhesive strip, in particular as a hot melt adhesive / hot melt adhesive strip. Such an adhesive strip ensures secure adhesion of the sealing or plastering strip to the building component during assembly and plastering. The adhesive strip is preferably extruded in the production of the one-piece sealing or plastering strip. When the adhesive strip is placed in an oblong depression at the back of the base region, it is particularly reliably connected to the sealing or plastering strip, its position is precisely defined, and lateral migration of the adhesive strip is avoided.

In an alternative embodiment of the invention, the fastening means is designed as an adhesive tape strip, in particular as double-sided adhesive tape strip. With the underside, the sealing or plaster molding adheres to the building component, thus ensuring at least temporary attachment. The adhesive tape strip can preferably be glued to the sealing or scraper strip side with a foot portion of the base region standing to the rear. This foot section may be an integral part of the base section.

Both in the formation of the fastener as an adhesive strip and in the formation of the fastener as a tape strip, as long as the fastener adheres to the building component, an additional sealing effect is provided in addition to the sealing effect provided by the expansion strip.

In an alternative embodiment of the invention, the attachment means receives a strip-shaped arrangement of suction cups. These can be integrated in a suction belt, which simplifies their handling and attachment to the sealing or plaster molding. Particularly well, the suction cups and / or the suction belt to be attached to the sealing or plaster molding when the base portion has on its back an elongated recess in which the suction cups and / or the suction belt is / is received. Thereby, the sealing or plastering strip can be easily and reliably equipped with suction cups and / or the suction belt, the suction cups and / or the suction belt are simply inserted into the elongated recess, in particular clipped. In the simplest embodiment, only one or two suction cups can be provided to ensure a mounting stop.

As an alternative to the fastening means exemplified here, other fastening means may also be used.

According to a particularly reliable embodiment of the invention, the sealing or plastering strip comprises two fastening means on the rear side of the base region which enclose the expansion strip. By providing two fasteners, a particularly reliable temporary attachment of the sealing or plaster molding during assembly and plastering can be provided.

These two fastening means, one of which is provided laterally of the expansion strip in the direction of the gap between the building component and thermal insulation or plaster layer and the second fastening means in the direction of the space between the building component and fastener away, there is additionally still a result provided supporting sealing effect, as long as the fastening means adhere to the building component or at least abut him.

In a further embodiment of the invention, in the delivery state of the sealing or plastering strip, the fastening means and the expansion strip are covered by a masking tape on the side facing away from the back of the base region, thereby preventing premature undesired attachment of the fastening means. By providing a common masking tape or covering strip for the fastening means and the expansion strip results in improved handling, and the preparation of the sealing or plaster molding for assembly can be carried out easily by peeling off a single masking tape.

It is particularly advantageous if the cover strip at the same time also forms the holding means which holds the expansion strip in its compressed state. An additional holding means can be dispensed with.

According to a further embodiment of the invention, the masking tape is fixed by adhesion to the fastening means. Alternatively, it is possible that the cover strip with at least one of its end portions at a different location of the sealing or plaster strip, in particular on its side or on the front detachably attached, in particular glued.

According to a further embodiment of the invention, the strip is designed as a plaster strip and is thus fixed by plastering or plastering on the thermal insulation or the plaster layer. For this purpose, it has a projecting forward, extending along the plastering strip web.

According to a further embodiment of the invention, a reinforcing fabric to be embedded in the plaster is attached to the plastering strip, and in particular to its web. By such a reinforcing fabric cracks in the plaster layer are safely avoided. The reinforcement fabric consists in most cases of a glass mesh fabric.

According to a further embodiment of the invention sets to the base area in the installed state of the plaster strip in the direction away from the gap between the building component and thermal insulation or plaster layer standing Einputzschenkel, which is plastered with and forms the edge for the outer plaster layer.

At the back of Einputzschenkels a flexible, in particular curved cover lip may be provided to ensure an additional protective effect to the outside at a normal distance between the building component and thermal insulation or plaster layer.

According to a further embodiment of the invention, a strip-shaped protective tab is provided, which is connected via a break-off material bridge of lesser thickness with the base area or with the plastering leg. On such a strip-like protective tab, the film is glued, which the window or door surface spans, and after the application of the plaster layer, this protective tab can be easily separated and removed.

According to a further embodiment of the invention, at least one of the fastening means is provided on the strip-shaped protective flap and is, after the installation of the plaster strip, removed together with this.

The sealing or plastering strip according to the invention is preferably made of a suitable plastic by extrusion.

The invention also relates to a transition between a building component and a thermal insulation or a plaster layer with a gap there, in which a sealing or plastering strip of the type described above is introduced such that the web and / or at least a portion of the front of Base area to the thermal insulation or the plaster layer.

In the installed state and with a normal gap dimension, the at least one fastening means at least temporarily fixes the sealing or plastering strip to the building component or is sealingly or adhesively attached thereto, and the expansion strip is sealingly applied to the building component. In an enlarged gap, for example as a result of temperature fluctuations, the at least one fastening means is released from the building component and its underside is at a distance therefrom. At the same time, the expansion strip has expanded somewhat further due to its expansion reserve and continues to be sealing against the building component.

The inventive transition between building component and thermal insulation or plaster layer thus a reliable and permanent sealing of the gap of the transition is provided regardless of the nature of the surface of the building component and regardless of the temperature-related changes in distance between building component and thermal insulation or plaster layer.

The invention also relates to a method for attaching a one-piece strip, in particular a sealing or plastering strip of the type described above, in a gap of a transition between a building component and a thermal insulation. In this case, first the holding means of the expansion strip is released, then the bar is attached to the building component such that the at least one fastening means at least temporarily to the building component attached. Then, the thermal insulation is fixed to the masonry or the like., That their corner region on the web of the bar and / or at least a part of the front of the base portion of the bar rests / abut.

If the strip is a plastering strip, the bar and / or the reinforcement fabric and / or the plastering leg is / are then plastered.

The triggering of the expansion strip is thus according to the invention before attaching the bar at the transition between the building component and thermal insulation, and the introduction of the bar takes place immediately after the triggering of expansion of the expansion strip.

The inventive method is simple to perform and results in a reliable and durable seal between window and door frame and the thermal insulation or the thermal insulation composite system as a result of work. The embodiments given above in terms of apparatus can also be used in procedural correspondence with the method according to the invention for attaching a one-piece sealing or plastering strip, these are not described again in detail in order to avoid repetition. This results in the same advantages already described above with respect to the sealing or plastering strip.

The terms "front" or "front" and "rear" or "rear" / "back" are understood in the following figures as lying in the drawing level above and below.

Fig. 1 shows a not yet fixed first grout 2 in cross section.

In the Fig. 1 shown first plaster strip 2 has a horizontally extending base portion 4, in the left region, a web 22 projects forward away. On the left outer side of the web 22, an upwardly extending reinforcing fabric 24 is secured by means of a weld 26. In this embodiment, this is a welded joint, which has been created by ultrasonic welding by means of a separately supplied welding string, or a permanent bond.

In a left-hand area of the rear side and in a right-hand area of the rear side of the base area 4, a first fixing area 6 and a second fixing area 12 are provided, which comprise a trough-shaped or semicircular adhesive strip receiving area 10 and 16 which faces rearward over a material bridge, in each of which a hotmelt adhesive strip 8 and 14 is received. Between these fixing regions 6 and 12, an expansion strip 18 is arranged, which adheres with its upper side to the rear side of the base region 4 or is welded thereto, and whose rear side lies approximately at the level of the rear side of the hot-melt adhesive strips 8 and 14. A masking tape 20 extends from left to right over the hotmelt adhesive strip 8, over the expansion strip 18 and over the hotmelt adhesive strip 14. This masking tape 20 adheres with its left region to the underside of the hotmelt adhesive strip 8 and to its right region the underside of the hot-melt adhesive strip 14, and presses with its intermediate region intermediate the expansion strip 18 upwards and holds it in its compressed state. In the present exemplary embodiment, the expansion strip 18 is about 10 mm wide and in its compressed state has a thickness of about 2.5 mm. The expansion strip 18 has a delayed expansion, that is, after the removal of the cover strip 20, this expands to a maximum Ausdehnposition, which is at a level well below the undersides of the hot-melt adhesive strips 8 and 14.

To the left of the first fixing region 6, in particular to the adhesive strip receiving portion 10, a Einputzschenkel 28 connects, which is plastered with and the outer left edge forms the edge for the top of the plaster layer. The top of Einputzschenkels 28, the left side of the web 22 and the transition region between them is provided with a channel profiling 30 to improve the adhesion of the plaster layer or the plaster layers on the first grout 2 by means of the thus enlarged surface.

From the underside of the left end of Einputzschenkels 28, a soft cover lip 32 extends rearwardly approximately to the level of the back of the hotmelt adhesive strips 8 and 14 and the back of the expansion strip 18 or even further down. The cover lip 32 is slightly curved to the left rear and protects in the installed state of the plaster strip 2 against moisture and water.

At the side end of Anputzschenkels 28 connects via a break-off material bridge lesser thickness 36, a strip-shaped protective tab 34, the front side is flat and the rear has a substantially perpendicular rearwardly projecting spacer web. The strip-shaped protective flap 34 has on its front side an adhesive layer to which a protective film, not shown here, can be glued.

The cross section of the plaster strip 2 and the plaster strips described below is consistent over the entire length, so that the plaster strips can be easily prepared by extrusion. The covering lip 32 made of a softer material relative to the base material of the first plastering strip 2 and the adhesive strips can be coextruded.

Fig. 2 (a) shows the introduced in a transition between a thermal insulation 40 and a window frame 38 first grout 2 in horizontal section in a first state with a small gap extent, and Fig. 2 (b) shows them in horizontal section in a second state with large gap expansion.

In the following figures, the window frame 38 can be provided, in particular, with a nanoparticle-coated surface, not shown separately, so that only adhesion but not permanent adhesion can be achieved.

In the Fig. 2 (a) the first plaster strip 2 has been mounted on the window frame 38 after removal of the cover strip 20, in such a way that the hot-melt adhesive strips 8 and 14 adhere to the front of the window frame 38 or at least temporarily secure the plaster strip 2 thereto. The expansion strip 18 rests with its underside on the front side of the window frame 38. Then, the heat insulation 38 has been fastened, in such a way that the right side of the web 22 of the first grout 2 and the adjacent thereto to the right front of the base portion 4 abut the corner region of the insulation 40. Thus, the gap 42 is reliably sealed by the base region 4 with the two hot-melt adhesive strips 8 and 14 and with the expansion strip 18 to the outside. This seal is still supported by the also applied to the window frame 38 cover lip 32. The gap has a width of 3 mm in the present exemplary embodiment.

The area of the first plaster molding 2 between the right side of the web 22, which rests against the insulation 40 and the plastering edge of Anputzschenkels 28 together with the reinforcing fabric 24 and the channel profile 30 is plastered by means of a first layer of plaster 44 and a second layer of plaster 46 and thus reliable the thermal insulation 40 attached. The strip-shaped protective flap 34 has been separated after completion of the plastering work along the break-off material bridge 36, so that the strip-shaped protective flap 34 in Fig. 2 (a) no longer exists.

According to Fig. 2 (b) For example, the gap 42 has increased due to temperature-induced shrinkage of the thermal insulation 40, ie, the distance between thermal insulation 40 and window frame 38 has increased, so that the hot-melt adhesive strips 8 and 14 and the cover lip 32 no longer abut or adhere to the window frame 38 but rather that the hotmelt adhesive strips 8 and 14 and the covering lip 32 are at a distance from the window frame 38. The expansion strip 18, however, has expanded so that it compensates for the increase in the gap and that its underside still sealingly abuts the window frame 38 and provides a reliable seal of the space between the thermal insulation 40 and window frame 38. In the present embodiment, the Gap increased from 3 to 5 mm, and the expansion strip 18 has a thickness of about 4 mm, but still seals reliably against driving rain. It is possible to form the expansion strip 18 such that it experiences an expansion of more than 100% from a compressed state up to a maximum expansion state, for example from 2.5 mm to more than 5.0 mm, and at the same time is impact-proof. It is even possible to form the expansion strip 18 such that it experiences an expansion of more than 200% from a compressed state to a maximum expansion state, for example from 2.5 mm to more than 7.5 mm, and at the same time is impact-resistant ,

Fig. 3 shows a not yet attached second grout bar 48 in cross section.

The second plaster strip 48 corresponds with respect to most of its elements of the first plaster strip 2, and like elements are also identified by the same reference numerals.

The second plaster strip 48 differs from the first plaster strip 2 in the formation of its fixing areas 50 and 56. These are formed as from the outer ends of the base portion 4 humped rear foot portions 52 and 58, on the flat underside adhesive tape strips 54 and 60 are attached , In an embodiment shown here, these can be double-sided adhesive tape strips, which are glued with their upper side to the flat undersides of the hump-shaped foot sections 52 and 58.

In the in Fig. 3 illustrated delivery state of the second mold bar 48, the tape strips 54 and 60 and the expansion strip 18 arranged therebetween covered with a cover tape 20 which adheres by adhesion to the undersides of the adhesive tape strips 54 and 60 and holds the expansion strip 18 arranged therebetween in its compressed state.

The adhesive tape strip 20 is in both plaster strips 2 and 48 each a piece to the left on the left fixing region 6, 50 and a piece far to the right on the right fixing portion 12, 56 via. The thus projecting ends can be easily gripped to attach the cover strip 20 before installing the plaster strip 2, 48 in the gap 42 between the thermal insulation 40 and window frame 38.

Fig. 4 (a) shows the arranged in the transition between the thermal insulation 40 and the window frame 38 second plaster strip 48 in horizontal section in a first state with a small gap expansion and Fig. 4 (b) shows them in horizontal section in a second state with large gap expansion

In Fig. 4 (a) the hump-shaped foot sections 52, 58 are fixed to the window frame 38 by means of their adhesive tape strips 54 and 60. The gap between the thermal insulation 40 and the window frame 38 is reliably sealed off to the outside by the expansion strip 18, by the adhesive tape strips 54 and 60 and by the cover lip 32. With enlarged gap according to Fig. 4 (b) For example, the adhesive tape strips 54 and 60 and the cover lip 32 are arranged at a distance from the window frame 38. The expanded expansion strip 18 continues with its underside still on the window frame 38 and seals the gap between the thermal insulation 40 and window frame 38 reliably and permanently.

Fig. 5 shows a not yet attached third plaster molding 62 in cross-section and a perspective view of a suction cup 66 used therein.

The third plaster molding 62 corresponds to most of its elements of the first plaster molding 2, and like elements are also identified by the same reference numerals.

The fixing regions 64 and 70 are designed as rows of suction cups 72 which are used in the third plastering strip 62 and which are respectively inserted into groove-shaped or semicircular suction cup receiving regions 68 and 72, in particular clipped into them. The masking tape 75, which covers the suction cups 66 and 72 and also holds the expansion strip 18 in its compressed state, extends to the left over the cover lip 32, the spacer web of the protective flap 34 over the end of the protective flap 34 to the front of the protective flap 34 and attached there by means of a bond, not shown. To the right of the right suction cup row 72, the cover tape 75 extends upwardly and is fixed to the right wall of the right suction cup receiving portion 74 by bonding.

Fig. 6 (a) shows the arranged in the transition between the thermal insulation 40 and the window frame 38 third plaster strip 62 in horizontal section in a first state with a small gap expansion and Fig. 6 (b) shows them in horizontal section in a second state with large gap expansion.

In the installation situation of the third cover strip 62 according to Fig. 6 (a) the temporary attachment of the plaster strip 62 is achieved on the window frame 38 by an adhesion of the suction cups 66 and 72. By the expansion strip 18, supported by the cover lip 32, a reliable sealing of the gap between the thermal insulation 40 and window frame 38 is achieved to the outside. In the enlarged distance according to Fig. 6 (b) the suction cups 66 and 72 and the cover lip 32 are arranged at a distance from the thermal insulation 38. The expansion strip 18 has further expanded to compensate for the increase in distance, and it is still sealingly abutting the window frame 38 with its underside. Thus, a permanent and reliable sealing of the gap between thermal insulation 40 and window frame 38 can be achieved to the outside.

Fig. 7 shows a not yet attached fourth grout bar 76 in cross-section and a perspective view of a used therein suction belt 80 with integrated therein used suction cups 82nd

The fourth plaster bar 76 corresponds to the third plaster bar 62 with respect to most of its elements, and like elements are also identified by the same reference numerals.

Instead of providing rows of separate suction cups 66 and 72, in the fourth plaster bar 76, the suction cups 82 and 90 are integrated into suction belts 80 and 88, and a first suction belt 80 is inserted into the semicircular suction channel receiving portion 84 of the first fixing portion 78 and also, a second suction belt 88 having suction cups 90 integrated therein is inserted into a semicircular suction channel receiving portion 92 of the second fixing portion 86.

Fig. 8 (a) shows arranged in the transition between the insulation 40 and the window frame 38 fourth grout 76 in horizontal section in a first state with a small gap expansion; and Fig. 8 (b) shows them in horizontal section in a second state with large gap expansion.

In the installation position according to Fig. 8 (a) the fourth grout bar 76 is attached to the window frame 38 by means of the integrated suction cups 82. The sealing effect is achieved by the expansion strip 18, by the suction belts 80 and 88, which also bear tightly against the window frame 38, and reached by the cover lip 32.

In the representation of the increased distance between the thermal insulation 40 and window frame 38 according to Fig. 8 (b) the bottoms of the suction belts 80 and 88 and the integrated suction cups 82, 90 and the cover lip 32 are arranged at a distance from the window frame 38. Due to the expansion of the expansion strip 18 ensures that the underside is still sealingly applied to the window frame 38 and seals the gap between the thermal insulation 40 and window frame 38 to the outside.

Fig. 9 shows a not yet fixed fifth grout 94 in cross section.

The fifth plaster bar 94 corresponds to most of its elements of the second plaster bar 48, and like elements are also identified by the same reference numerals.

The fifth plaster strip 94 differs from the second plaster strip 48 in the formation of its fixing regions 96 and 102. Instead of a hump-shaped formation, the fixing regions 96 and 102 have a staple-shaped formation or essentially the shape of an L or an inverted L, and they extend from the left or right end of the base portion 4 to the rear. Double-sided adhesive tape strips 100 and 106 are applied to the rear sides of the straight foot sections 98 and 104. Analogous to the second plaster strip 48, a cover strip 20 is provided which adheres to the adhesive tape strips 100 and 106 and which holds the expansion strip 18 arranged therebetween in its compressed state.

Fig. 10 (a) shows the arranged in the transition between the thermal insulation 40 and the window frame 38 fifth grout 94 in horizontal section in a first state with a small gap expansion; and Fig. 8 (b) shows them in horizontal section in a second state with large gap expansion.

The presentation largely corresponds to the representation in Fig. 4 Here, the staple-shaped foot portions 98 and 104 are fixed by means of their adhesive tape strips 100 and 106 on the window frame 38.

In both representations, the expansion strip 18 results in a reliable seal toward the outside, in the representation with a small gap extent according to Fig. 10 (a) This sealing effect is still reinforced by the fixing regions 96 and 102.
