Abstract

A plaster sealing strip for connecting a structural element, in particular a window or a door, to a building wall has a profile body which includes a base leg for attachment to the structural element and/or the building wall and a plaster leg for plastering on the building wall. The cleaning leg is articulated to the base leg in such a way that it can be folded between an installation position in which it is aligned at least essentially perpendicular to the base leg and a storage position in which it is aligned at least essentially parallel to the base leg. In addition, the plaster sealing strip is designed in such a way that it can be rolled up when the plaster leg is in the storage position.

Description

The invention relates to a plaster sealing strip for connecting a structural element, in particular a window, a door, a roller shutter box or the like, to a building wall.

Plaster sealing strips are used to seal joint areas that are formed between a component and parts of a structure, such as a building wall, for example between the frame of a window or a door and the adjoining masonry. Plaster sealing strips of the type mentioned at the outset are also used at transitions between differently designed wall or facade sections, such as at the transition point between wood paneling and a plaster facade. Accordingly, facade elements, wall cladding elements, panels and the like also form structural elements within the meaning of the present disclosure. Apart from the sealing effect, plaster sealing strips ensure a visually appealing finish to a layer of plaster applied to the building wall.

To seal a joint between the component and the building wall, the plaster sealing strip can be used at least partially in this joint. For stable attachment of the sealing plaster strip and/or to reinforce a corner edge at the transition from the building wall to the joint, it is also advantageous to plaster the sealing plaster strip at least partially on the building wall, i.e. to embed it in a layer of plaster applied to a wall surface of the building wall. The building wall can be designed in particular as a thermal insulation composite system, so that the plaster sealing strip is attached to a thermal insulation of the building wall and plastered. For fastening the plaster sealing strip it is therefore advisable to provide structures on the plaster sealing strip that enable stable plastering.

A plaster sealing strip is typically elongated and can extend over a few meters. For example, a plaster sealing strip can have a length of about 2.5 m or about 3 m. As a result, a plaster sealing strip can be comparatively bulky, which can make handling more difficult. This also results in special requirements for the storage and transport of plaster sealing strips. Storage and transport could be simplified in that the plaster sealing strip is not rigid, so that it is less bulky. However, the typical structure of a sealing plaster strip, which (viewed in cross section) generally has several sections aligned at an angle to one another, in particular a plaster leg for the said plastering, precludes the flexibility of the sealing plaster strip. The cleaning leg could in principle be omitted or only be made very short. However, this would then affect the arrangement and attachment of the plaster sealing strip on the building wall.

It is an object of the invention to provide a plaster sealing strip that can be arranged and fastened particularly reliably for the structural connection of a component to a building wall, in particular to the building wall, and is comparatively easy to handle, in particular can be stored and transported in a compact manner.

The object is achieved by a sealing plaster strip with the features of claim 1. Advantageous embodiments of the invention result from the dependent claims, the present description and the figures.

The plaster sealing strip according to the invention for the structural connection of a component, in particular a window or a door, to a building wall has a profile body that includes a base leg for attachment to the component and / or the building wall and a plaster leg for plastering on the building wall. The profile body can be made of plastic or metal, for example sheet metal. The profile body is preferably made of plastic, in particular a PVC.

The profile body advantageously has an elongate shape and preferably has an at least essentially constant cross section along its entire length. At least in a built-in configuration, i. H. in a state that the plaster sealing strip assumes during and after installation on the component and the building wall, the longitudinal extension has a straight course. As will be explained below, the profile body can also extend along a curved course in other configurations of the plaster sealing strip. The cross section at a certain point of the profile is defined perpendicularly to the direction of the profile at the respective point. Deviations from the constant cross-section can in particular be limited to the fact that at least parts of the profile body, in particular the said plaster leg, have a perforation and/or other openings and/or a surface profile, for example ribs, notches and/or knobs, to improve the plaster grip .

As legs of the profile body, the base leg and the cleaning leg are each flat. In relation to the cross section of the profile body, the legs correspond to straight sections which preferably have an at least essentially constant thickness. Deviations from the constant thickness can in particular be limited to the fact that the respective leg, in particular the plaster leg, has a perforation and/or other openings and/or a surface profile, for example grooves, notches and/or knobs, to improve the plaster grip. When in the following reference is made to an orientation or extension of a respective leg (or a comparable section of the plaster sealing strip) is discussed, this is to be understood in relation to the course of the straight section of the cross section of the profile body that corresponds to the leg.

The base leg is used for attachment to the component and/or the building wall insofar as the plaster sealing strip is designed to be attached to the base leg on the component and/or the building wall. In this case, the base leg is preferably connected at least to the component, it being possible for this connection to include, in particular, gluing. The base leg can also be connected to both the component and the building wall at the same time. In this case in particular, the connection (in addition to another type of connection, such as gluing, or exclusively) can be non-positive, in particular by clamping at least part of the base leg, for example the fastening section of the base leg described below, between the component and the building wall.

The plaster leg is intended for plastering on the building wall in that the plaster sealing strip is designed so that it is arranged with the plaster leg on the building wall and the plaster leg is plastered on the building wall, so that the plaster leg is embedded in a plaster layer applied to the building wall. In this respect, the plaster leg also contributes to the attachment of the plaster sealing strip to the building wall. As a rule, however, the plaster leg is plastered in later than the attachment of the base leg to the component and/or the building wall. For a particularly stable embedding of the plaster leg in the plaster, the plaster leg preferably has a perforation through which the plaster can penetrate the plaster leg during plastering. In addition, the adhesion of the plaster to the plaster leg can be improved in that the plaster leg has at least one side, preferably both sides, a surface profile that improves the plaster grip.

The length of the base leg (i.e. the extension of the base leg transversely to the longitudinal extension of the profile body) can be limited by the depth of a joint between the component and the building wall and also does not need to be particularly large, regardless of the depth of the joint, since there is more to it It is important that the plaster sealing strip reliably seals the joint rather than extending particularly deep into the joint. On the other hand, a great length is advantageous for the plaster leg (i.e. the extension of the plaster leg transversely to the longitudinal extension of the profile body) with regard to a long-term stable attachment of the plaster sealing strip to the building wall. It is therefore preferred if the cleaning leg has at least no shorter length, preferably a greater length, than the base leg.

According to the invention, the cleaning leg is articulated to the base leg, advantageously in such a way that it can be folded between an installation position in which it is aligned at least essentially perpendicular to the base leg and a storage position in which it is aligned at least essentially parallel to the base leg . Preferably, the alignment of the cleaning leg in the installed position deviates from an alignment perpendicular to the base leg and the alignment of the cleaning leg in the storage position from an alignment parallel to the base leg by no more than 20°, preferably by no more than 10°, in particular by no more than 5°.

The installation position of the plaster leg corresponds to an installation configuration of the sealing plaster strip in which it is installed. In this respect, when the plaster leg is in the installation position, the plaster sealing strip can have a structure which, in principle, can at least largely correspond to the structure of a conventional plaster sealing strip. However, this structure can also be changed in the plaster sealing strip according to the invention due to the articulated coupling of the plaster leg to the base leg, namely in particular in that the cleaning leg is folded out of the installed position into the storage position.

The articulated coupling preferably takes place directly between the two legs (the base leg and the cleaning leg). In this case, one of the two ends of the cleaning limb, in particular, can strike one of two mutually opposite side surfaces of the base limb, transversely to the longitudinal extent of the profile body. Along the area of this impingement, the cleaning leg can then be coupled to the base leg via an articulated connection, so that the cleaning leg as a whole can be folded relative to the base leg, in particular about an axis which is oriented parallel to the longitudinal extension of the profile body and through said end the extension of the cleaning leg runs.

In the installed position, the cleaning leg can protrude perpendicularly from the base leg and thus at least essentially form a T-shape with the base leg. From this installed position, the cleaning leg can be folded through about 90° relative to the base leg into the storage position, in which it is then parallel to the base leg and preferably rests at least partially on the base leg. The cleaning leg preferably does not change its shape when it is folded over, but instead has the same shape (in cross section) both in the installation position and in the storage position, in particular a straight course. The base leg also preferably does not change when the cleaning leg is folded over, but has the same shape (in cross section) both in the installed position and in the storage position of the cleaning leg, in particular a straight course.

According to the invention, the plaster sealing strip can be rolled up when the plaster leg is in the storage position. This is made possible in particular by the parallel arrangement of the cleaning leg and the base leg in the storage position. In other words, the plaster sealing strip, in particular with regard to its structure and its material, is designed to be rolled up when the plaster leg is in the storage position. When rolled up, the profile body then no longer runs straight along its length, but is wound in a spiral shape around an axis that is perpendicular to the length and parallel to the length of the base leg (related to the cross section), so that the plaster sealing strip (except for the end sections of its Longitudinal extension) rests with its bottom on the top of the next winding or with its top on the bottom of the next winding. The underside of the plaster sealing strip (and also an underside of the base leg) can be aligned either radially inwards or radially outwards with respect to the axis mentioned, while the upper side of the plaster sealing strip (or an upper side of the base leg) is aligned radially in the opposite direction.

The ability to be rolled up is not limited to the two legs, but the sealing plaster strip can be rolled up as a whole, including possibly further legs and/or other sections of the sealing plaster strip and/or elements provided on the sealing plaster strip, such as the holding means described below. In order not to impair the ability to be rolled up, however, preferably no other section of the sealing plaster strip and no element provided on the sealing plaster strip that is not aligned at least essentially parallel to the base leg in the storage position of the plaster leg has a greater extent transversely to the longitudinal extent of the profile body than the base leg or the cleaning leg. In particular, the plaster sealing strip preferably has no structures that protrude further from the base leg perpendicular to the base leg than the plaster leg in its installed position.

With regard to the material of the plaster sealing strip, in particular of the base leg and the profile leg, the ability to be rolled up can be supported by selecting a material with a sufficiently large modulus of elasticity. A PVC is particularly suitable for this purpose. For rollability, however, it is not only the material properties that are important, but also the material thickness. Therefore, many different materials can basically be considered for the plaster sealing strip due to their respective elasticity. In particular, different materials can also be used for different parts of the plaster sealing strip, e.g. B. various PVC, which can preferably be coextruded. By determining the material thickness of a particular part of the plaster sealing strip, its flexibility can then be adjusted (at least to a certain extent) as desired for rolling up.

Through the use of a suitable material and the choice of a corresponding material thickness, the base leg and the cleaning leg can be designed just so flexibly that they can advantageously be rolled up. It is difficult to avoid the fact that they also have a comparatively high degree of flexibility with regard to bending about an axis parallel to the longitudinal extension of the profile body. In this direction, however, the base leg and the plaster leg do not need to have a particularly high degree of rigidity, since they are preferably arranged during assembly in such a way that they rest against the component or the building wall and are thereby stabilized. In addition, the vertical alignment of the plaster leg relative to the base leg in the installed position contributes to stabilizing the structure of the plaster sealing strip in its installed configuration.

When the plaster leg is folded into its storage position and the plaster sealing strip is rolled up, this state corresponds to a storage configuration of the plaster sealing strip. In this storage configuration, the plaster sealing strip is arranged in a particularly compact manner, so that it can be stored and stored comparatively easily can be transported. For example, when rolled up, the plaster sealing strip can have an inner diameter of the order of a few 100 mm, for example in the range from 300 mm to 1000 mm, in particular around 500 mm or 750 mm, so that it has a core with a diameter of, for example 300 mm, 400 mm, 500 mm, 750 mm or 1000 mm can be stored and transported rolled up.

Before assembly or as part of assembly, the sealing plaster strip is unrolled (it is also possible to unroll only a portion of the sealing plaster strip that has the required length and then separate it from the rest) and the plaster leg is then folded out of its storage position into its installation position, so that the sealing plaster strip is in its place Occupies installation configuration, in which they can then be arranged at the transition between the component and the building wall, fixed and plastered. The design of the plaster sealing strip according to the invention enables on the one hand a reliable connection to the building wall by means of an advantageously long plaster leg that can be plastered in, which protrudes perpendicularly from the base leg in the installed configuration, and on the other hand a space-saving arrangement of the plaster sealing strip in its storage configuration, in which the plaster leg is parallel, despite the long plaster leg rests against the base leg.

According to an advantageous embodiment, the cleaning leg is coupled in an articulated manner to the base leg via an articulated connection made of a material that is softer than the material of the cleaning leg and/or the base leg. The articulated connection can be designed in particular as a flexible connection. A soft PVC, for example, can be considered as the material. Such an articulated connection can in particular be coextruded with the cleaning leg and/or the base leg. This simplifies the manufacture of the plaster sealing strip. Such an embodiment allows the cleaning leg and the base leg to be connected to one another in a materially joined manner and yet relative to one another be foldable. As already mentioned above in general for the sealing plaster strip or parts of the sealing plaster strip, the flexibility of the articulated connection can also be advantageously adjusted by selecting a material thickness that is suitably adapted to the elastic properties of the material.

According to a further advantageous embodiment, the base leg is designed to be inserted with a fastening section into a joint between the building wall and the component, with the cleaning leg extending along this fastening section in the storage position. Said gap can be laterally delimited on the one hand by a side surface of the building wall and on the other hand by a surface of the component, in particular a window frame of the component. The side surface of the building wall and the surface of the component are preferably parallel to one another.

The fastening section can in particular correspond to that part of the base leg which is inserted into the joint during assembly and is therefore accommodated in the joint in the assembled state. The remaining part of the base limb can form a cover section of the base limb, with which the base limb protrudes from the joint in the assembled state. In other words, the plaster sealing strip can be designed to be inserted with a fastening section of the base leg into a joint between the building wall and the component and to protrude from the joint with a cover section adjoining the fastening section, in particular in that the cover section extends beyond the plane of a wall surface of the Building wall protrudes, on which the plaster leg is plastered. The cleaning leg can be coupled to the base leg along a transition between the fastening section and the facing section. Conversely, the base leg is viewed along the coupling of the cleaning leg in a fastening section, with which the base leg is inserted into the joint, and a facing section with which the base leg protrudes from the joint.

The surfaces of the fastening section (which are aligned in a direction perpendicular to the longitudinal extension of the profile body and to the extension of the base leg) are preferably smooth, in particular in contrast to the cover section, which is at least on the side on which the cleaning leg is coupled to the base leg. preferably has a surface profile to improve plaster adhesion.

Since the cleaning leg extends along the fastening section in the storage position, the cleaning leg, starting from the installation position in which it protrudes at least substantially perpendicularly from the base leg, must be foldable at least in the direction of the fastening section to an alignment parallel to the base leg. In principle, the cleaning leg can also be folded in the opposite direction to an alignment parallel to the base leg. However, this is not mandatory. Rather, the ability of the cleaning leg to fold in this direction can also be limited, so that it either cannot be folded from the installed position in this direction at all or at least cannot be folded into a position aligned parallel to the base leg, in which it would extend along the panel section mentioned can. The fact that the cleaning leg cannot be folded away from the installed position in the direction of the storage position can result, for example, from the fact that the cleaning leg has structures on its side pointing away from the fastening section, such as the web described below, which Oppose base leg parallel arrangement of the cleaning leg along the blind section.

In particular, the fact that the plaster leg is folded in the storage position to that side of the base leg out, which is in the joint between the building wall and the component is used, the plaster leg can also be, at least slightly, biased against the building wall in the installed position by the articulated connection between the plaster leg and the base leg. This can also contribute to a reliable hold on the building wall.

According to a further advantageous embodiment, the cleaning leg has a contact surface for contacting the building wall, in particular a wall surface of the building wall, and in the storage position lies with this contact surface on the base leg, in particular on the named fastening section of the base leg. In other words, the plaster sealing strip is designed to be arranged with a contact surface of the plaster limb against a wall surface of the building wall, the plaster limb resting against the base limb with this contact surface in the storage position. Depending on the length of the cleaning leg, the cleaning leg lies in the storage position with the entire contact surface or at least with part of the contact surface on the base leg.

The fastening section of the base leg can also have a contact surface with which it rests against a side surface of the building wall that laterally delimits the mentioned joint between the building wall and the component, which can be aligned perpendicular to the mentioned wall surface of the building wall. In particular, the plaster sealing strip can be designed to be arranged on the building wall in such a way that the contact surface of the plaster leg rests on the named wall surface of the building wall and the contact surface of the base leg on the named side surface of the building wall. The articulation between the plaster leg and the base leg is thus preferably arranged at an edge along which the wall surface and the side surface of the building wall meet.

A surface of the plaster leg which is aligned opposite to the said contact surface of the plaster leg can form a plastering surface which is designed for plaster to be applied thereto. The plaster leg can thus be arranged with the contact surface lying against the building wall and then be plastered by applying plaster to the plaster surface on the building wall. At least the plastered surface, possibly also the contact surface of the plaster limb, can have the named surface profiling, in particular in the form of ribs, notches and/or nubs, to improve plaster clawing.

According to a further advantageous embodiment, the plastering limb has a plastering surface which points away from the base limb in the storage position and on which a web protruding perpendicularly from the cleaning limb is formed. This plastering surface is, in particular, the plastering surface mentioned above, which is opposite the said contact surface of the plaster leg. The web projecting perpendicularly from the plastering surface can contribute to good adhesion of plaster, particularly in a corner area between the plaster leg and the base leg. In addition, the outer edge of the web, which corresponds in cross section to a free end of the web, can also serve as a pull-off edge for the application of plaster. The web is preferably designed to be comparatively short so as not to impair the rollability of the plaster sealing strip. For example, the web can have a length (ie an elongate extent in cross section) which is at most 10% of the length of the cleaning leg. However, a short web can also serve as a removal aid, namely, for example, at least for a base coat and/or reinforcement plaster, to which one or more further coats of plaster can optionally be applied.

According to a further advantageous embodiment, the base leg has an upper side, to which the plaster leg is coupled, and an underside opposite the upper side, on which holding means for fastening the plaster sealing strip to the component are provided. At least the underside of the base limb, optionally also the top of the base limb, preferably has a smooth surface. The designation of the sides of the base leg as "top" or "bottom" is only used for conceptual differentiation and does not imply any restriction to a fixed spatial orientation of the sides. For example, the plaster sealing strip can be mounted in the area of vertically running joints between a building wall and a component, the top and bottom of the base leg then also being arranged to run vertically and are then aligned pointing in horizontal directions.

Said holding means can be used both to connect the base leg (and thus the entire plaster sealing strip) to the component and to support the base leg in the joint. To connect the base leg to the component, the holding means can, for example, comprise means for an adhesive connection, for example by comprising at least one, in particular double-sided, adhesive tape, preferably foam adhesive tape. For the attachment of the base leg to the component, however, an adhesive connection is not absolutely necessary, but the attachment can, for example, also (exclusively or inter alia) take place with a force fit. In this case, the base leg can be clamped, in particular by the holding means or at least part of the holding means, when it is inserted into the joint between the building wall and the structural element.

For this purpose, but also in principle, it is advantageous if the holding means are flexible, elastic, in particular stretchable or compressible and/or pliable. Such training not only contributes to a non-positive attachment of the base leg in the joint, but also to not impairing the ability to roll up the plaster sealing strip. In addition, it enables a certain amount of movement compensation, ie an adaptation of the plaster sealing strip to a change in the size of the joint, which can narrow or widen, in particular due to temperature.

Depending on the design of a respective holding means, the holding means can be integrally connected to the base leg, for example coextruded with the base leg, or formed separately from the base leg and attached thereto, for example glued.

According to an advantageous embodiment, the holding means comprise (at least) two flexible spacers, which protrude from the underside of the base leg and are aligned obliquely in such a way that their distance from one another increases as the distance from the base leg increases. Because the spacers protrude from the base leg, you can span the joint in particular. The base limb can then bear in particular with the aforesaid contact surface on the aforesaid side surface of the building wall and can be supported via the spacers on the surface of the structural element delimiting the joint on the opposite side.

One of the two spacers can be arranged, for example, at one end of the extension of the base leg, namely that end with which the base leg is inserted into the joint in front. The other spacer can be arranged in particular in the region of the coupling of the cleaning limb to the base limb, specifically in particular directly opposite to this coupling. In this respect, the two spacers can at least essentially flank the mentioned attachment section of the base leg, ie can be arranged at opposite ends of the attachment section.

Preferably both spacers are co-extruded with the base leg. Due to the flexibility of the spacers, the plaster sealing strip can be clamped in the joint with the fastening section of the base leg, to which the inclined position of the spacers also contributes. The spacers can each extend from the base leg in a direction which encloses an angle with the extent of the base leg which is preferably in the range between 50° and 80°, in particular approximately 65°.

According to a further advantageous embodiment, the holding means comprise a pre-compressed or compressible joint-sealing tape which is attached to the base leg, in particular to the underside of the base leg. Such a joint sealing tape is typically designed to expand during or after installation in order to seal the joint between the building wall and the component into which the plaster sealing strip is used with at least part of its base leg. The joint sealing tape can in particular be designed as a so-called compriband. In addition, the joint sealing tape can be provided with a respective adhesive layer on one or both sides in order to be adhesively connected to the base leg, in particular to the named fastening section of the base leg, on the one hand, and to be adhesively connected to the component on the other hand. In particular, it can be provided that the plaster sealing strip is glued to the component via the joint sealing tape during assembly.

According to a further advantageous embodiment, the joint sealing tape is arranged between the two spacers mentioned, the spacers having an extent perpendicular to the base leg which corresponds to a partially compressed expansion of the joint sealing tape. The specified extension of the spacers relates to their respective extension in a relaxed Resting position, ie when they are not deformed by any external force acting on them (e.g. bent, compressed or expanded), i.e. in particular the plaster sealing strip is neither rolled up nor clamped in the joint. In the partially compressed state, the joint sealing tape is neither maximally expanded nor maximally compressed, but can be both expanded and compressed within the scope of its elasticity without being damaged, namely preferably compressed by at least 2 mm and/or compressed by at least 3.5 mm be extended. In this way, a good movement compensation can be guaranteed in the event of temperature-related enlargements or reductions in the joint.

According to a further advantageous embodiment, in a storage configuration of the sealing plaster strip, in particular in the storage configuration described above, the plaster leg is in the storage position and the sealing plaster strip is rolled up in such a way that the joint sealing tape is thereby kept in a pre-compressed state. In this pre-compressed state, the joint sealing tape is in particular more strongly compressed than in the partially compressed state mentioned. In other words, the plaster sealing strip is wound so tightly in the storage configuration that the joint sealing tape is compressed between two windings and is thereby held in its pre-compressed state. The joint sealing tape can then expand independently only after the plaster sealing strip has been unrolled, which in particular only takes place during assembly. Such a design of the plaster sealing strip means that additional means that would otherwise be required to keep the joint sealing tape compressed can be dispensed with.

According to a further advantageous embodiment, the plaster sealing strip comprises a flexible cover lip, which protrudes from the base limb and is aligned obliquely in such a way that it extends beyond the base limb with respect to a direction parallel to the base limb. The cover lip can also be considered as part of said holding means as it contributes to the support of the base leg on the building element. Furthermore, the covering lip can in particular protrude from the mentioned underside of the base leg, namely preferably from an edge of this underside. The direction in which the covering lip extends from the base limb encloses an angle with the extension of the base limb, which is preferably in the range between 50° and 80° and can in particular be approximately 65°.

Because the cover lip protrudes from the base leg, it can extend across the width of the joint and thus cover the joint to the outside. In contrast to the spacers mentioned, the cover lip is preferably not provided on the fastening section, but rather on the said cover section of the base leg and is therefore arranged outside the joint in the installed state of the plaster sealing strip. Furthermore, the cover lip preferably extends further perpendicularly to the base leg and is thinner than the two spacers mentioned, so that it is bent more than the spacers by the component when the plaster sealing strip is in the installed state. As a result, a free end of the covering lip can bear against the component in the assembled state. In addition, the covering lip extends beyond the base leg in the direction away from the joint, so that it covers the joint from the outside. In this way, the cover lip can form a curved, flush transition that appears almost seamless between the building wall and the component. In addition, the cover lip also contributes to sealing the joint.

According to a further advantageous embodiment, a reinforcing fabric is fastened to the cleaning leg, which in the installed position extends beyond the cleaning leg in the direction pointing away from the base leg. The reinforcement fabric can, for example, be sewn, glued or welded to the cleaning leg. With such a reinforcement fabric, the plaster sealing strip fixed to the building wall over a larger area by plastering. Due to the design as a fabric, through the mesh of which plaster can penetrate, the reinforcement fabric can be embedded in the plaster in a particularly reliable and simple manner.

According to a further advantageous embodiment, the plaster sealing strip comprises a tear-off tab, which is connected to the base limb, in particular to the said panel section of the base limb, via a predetermined breaking point. The tear-off tab can be connected to the base leg via the predetermined breaking point, in particular at an end of the base leg opposite the named fastening section. The tear-off tab is preferably arranged as an extension of the base leg, so that the tear-off tab and the base leg lie at least essentially in one plane. Such a tear-off tab can be used to attach a protective film, with which the component can be protected from being soiled with plaster when plastering the building wall. To attach the protective film, the tear-off tab can have an adhesive tape or be provided with an adhesive layer. After plastering, the tear-off tab (and with it the protective film) can then be separated from the base leg along the predetermined breaking point.

The tear-off tab can be made of the same material as the base leg and/or the cleaning leg. The predetermined breaking point can be formed, for example, by a material bottleneck and/or a perforation. Alternatively or additionally, the predetermined breaking point can be formed by a section made of a material that is softer than the material of the tear-off tab and than the material of the base leg. The tear-off tab, the predetermined breaking point and the base leg can be coextruded.

In the following, the invention is explained further by way of example only with reference to the figures.

shows a further embodiment of a plaster sealing strip according to the invention in a cross-sectional view, the plaster leg being shown in its storage position.

In the figures, a plaster sealing strip 11 according to the invention is shown in cross section. The in the Figures 1 and 2 embodiment shown and in 3 embodiment shown are largely the same. The plaster sealing strip 11 comprises a profile body 13 with a base leg 15 and a plaster leg 17. The profile body 13 has an at least essentially constant cross section along a longitudinal extension that runs perpendicularly through the plane of the figures. The base leg 15 and the cleaning leg 17 are each flat, so that in cross section they each extend along a straight line (perpendicular to the aforementioned longitudinal extension of the profile body 13), and are both made of the same material, namely PVC.

With one end of its extension, the cleaning leg 17 is coupled in an articulated manner to an upper side 21 of the base leg 15 via an articulated connection 19 . The joint connection 19 is designed as a soft connection made of a soft PVC, which is softer than the PVC from which the base leg 15 and the cleaning leg are made 17 are formed. Because of the articulated coupling, the cleaning leg 17 can be folded relative to the base leg 15 . As a result, the cleaning leg 17 can, on the one hand, assume an installation position in which it is aligned at least substantially perpendicularly to the base leg 15 and which it can 1 occupies, on the other hand, the cleaning leg 17 can be folded out of this installation position into a storage position in which it is aligned at least substantially parallel to the base leg 15 and which it 2 takes.

The base leg 15 is divided into a fastening section 23 and a cover section 25 by the articulated connection 19 . The plaster sealing strip 11 is designed to fit with the fastening section 23 of the base leg 15 in a joint 26 between a building wall 27, in particular thermal insulation provided as part of this building wall 27, and a component 29, which is in particular a window or a door can be used and applied to the plaster leg 17 to a wall surface 31 of the building wall 27 and plastered there. In this way, the plaster sealing strip 11 serves to connect the building element 29 to the building wall 27.

In its storage position, the cleaning leg 17 is folded over relative to its installed position in the direction of the fastening section 23 of the base leg 15 and therefore extends, starting from the articulated connection 19, along the fastening section 23. Because of its length, the cleaning leg 17 protrudes beyond the base leg 15 (cf. 2 ).

At the end of the base limb 15 pointing in the opposite direction, a tear-off tab 35 is connected to the base limb 15 via a predetermined breaking point 33, which is essentially in one plane with the base limb 15 and is therefore arranged in its extension. The tear-off tab 35 is made of the same material as the base leg 15 and is used for attachment a protective film (not shown), which can be attached via an adhesive tape 37 provided on the tear-off tab 35 in order to protect the component 29 from plaster when plastering it. After assembly, the tear-off tab 35 with the protective film can be separated from the base leg 15 along the predetermined breaking point 33 .

As in 2 As can be seen, when the plaster leg 17 is in its storage position, the entire plaster sealing strip 11 is designed to be largely flat, since the base leg 15 and the tear-off tab 35 lie essentially in one plane and the plaster leg 17 rests directly adjacent to the base leg 15 . As a result of this and the selection of a sufficiently elastic material for the base leg 15, the plaster leg 17 and the tear-off tab 35, the plaster sealing strip 11 according to the invention can be rolled up about an axis which is parallel to the image plane of the figures and to the base leg 15 and the plaster leg 17. This makes it possible to store and transport the sealing plaster strip 11 in a particularly compact storage configuration, in which the plaster leg 17 is folded into the storage position and the entire sealing plaster strip 11 is rolled up.

For assembly, the rolled-up plaster sealing strip 11 can be unrolled and then the plaster leg 17 folded out into the installation position, so that the plaster sealing strip 11 can then be mounted on the joint 26 between the building wall 27 in the building element 29 . The fastening section 23 of the base leg 15 is inserted into the joint 26 in such a way that the upper side 21 of the base leg 15 rests in the region of the fastening section 23 on a side surface 39 of the building wall 27 that laterally delimits the joint 26 and the plaster leg 17 with a contact surface 41 on the to the side surface 39 vertical wall surface 31 of the building wall 27 is present. The articulated connection 19 is thereby essentially along an edge of the building wall 27 arranged at which the wall surface 31 and the side surface 39 of the building wall 27 meet.

The plaster sealing strip 11 is also attached to the component 29 as part of the assembly. For this purpose, holding means are provided on an underside 43 of the base leg 15 opposite the upper side 21 , which include two flexible spacers 45 on the one hand and a joint sealing strip 47 on the other. The two spacers 45 are arranged at opposite ends of the fastening section 23 and protrude obliquely from the underside 43 of the base limb 15 in such a way that their distance from one another increases as the distance from the base limb 15 increases. The spacers are so flexible that they can be widened by being inserted into the joint 26 so that they reliably support the base leg 15 in the joint 26 on the component 29 . In this way, the base leg 15 is non-positively fastened in the joint.

The joint sealing tape 47 is arranged between the two spacers 45 . While the spacers 45 are coextruded with the base limb 15 but are made of a material that is softer than the material of the base limb 15, the joint sealing tape 47 is designed as a double-sided adhesive foam tape and is glued to the underside 43 of the base limb 15. With its side pointing away from the base leg 15, the joint sealing strip 47 can be glued to the component 29 during assembly. This ensures that the joint 26 is reliably sealed by the joint sealing tape 47 . However, an adhesive connection to the component 29 is not absolutely necessary, since the joint sealing tape 47 is compressible and has such a thickness that when the fastening section 23 of the base leg 15 is inserted into the joint 26, it is compressed and thus prestressed against the component 29 .

Furthermore, a cover lip 49 is arranged at the end of the base leg 15, which is followed by the tear-off tab 35 via the predetermined breaking point 33, which, like the spacers 45, protrudes obliquely from the underside 43 of the base leg 15. The cover lip 49 is longer and thinner than the spacers 45 and extends beyond the extent of the base leg 15 due to its arrangement at the end mentioned. As a result, the cover lip 49 projects beyond the base leg 15 and, when the tear-off tab 35 is separated, forms a cover of the joint 26 that is visible from the outside. The cover lip 49 is also elastic, in particular flexible, so that its free end can be attached to the component 29 is flush and forms a largely continuous curved transition from the building wall 27 to the component 29 .

In the figures, the spacers 45, the joint sealing tape 47 and the cover lip 49 are each shown in the form that they assume without the action of an external force. In 1 it therefore appears as if these elements spatially overlap the device 29 . In fact, however, they are deformed by the component 29 during assembly, as a result of which the joint sealing tape 47 is compressed more than the shape shown and the spacers 45 and the cover lip 49 each point away from the joint sealing tape 47 in the direction shown in 1 shown shape deformed, in particular bent, so that they extend only to the surface of the component 29.

Even when the sealing plaster strip 11 is rolled up in its storage configuration, the spacers 45, the joint sealing tape 47 and the cover lip 49 can be pressed together between windings of the rolled up sealing plaster strip 11 and thereby in a similar way compared to the FIG 2 shown shape may be deformed. In particular, the rolling up maintains the joint sealing tape 47 in a pre-compressed state between the wraps. Because of their deformability and because of their comparatively small extension perpendicular to the extent of the base leg 15, the spacers 45, the joint sealing strip 47 and the covering lip 49 do not prevent the sealing strip 11 for plastering from being rolled up.

On the opposite side of the base leg 15 (i.e. on the side of the upper side 21 of the base leg 15), when the cleaning leg 17 is in its storage position, a web 51 extends perpendicularly to the base leg 15 in a direction pointing away from the base leg 15. The plaster leg 17 has this web 51 on a plastering surface 53 opposite the aforesaid contact surface 41 . The web 51 protrudes vertically from this plastering surface 53, with the web 51 having a comparatively small extent, which is in particular smaller than the respective extent of the spacers 45, the joint sealing strip 47 and the cover lip 49 perpendicular to the base leg 15 and less than 10% of the Extension of the cleaning leg 17 is.

The web 51 is provided in the vicinity of the articulation 19, in particular within the first quarter of the extent of the cleaning leg 17, starting from the end of the cleaning leg 17 with which it is coupled to the base leg 15. Because it protrudes from the plastering surface 53, the web 51 extends into the plaster layer 55 applied to the building wall 27 when the plaster leg 17 is plastered in. In this way, the web 51 contributes to the stability of the plaster layer 55 in the area of the transition between the building wall 27 and the component 29 at.

In addition, the clawing of the plaster on the plaster sealing strip 11 is also supported by the fact that the plaster leg 17 is provided with a surface profile in the form of ribs on both its contact surface 41 and its plastering surface 53 including the web 51, which are parallel to the longitudinal extent of the profile body 13 and regularly spaced apart from each other. The upper side 21 of the Base leg 15 in the area of said panel section 25 of the base leg 15, up to which the plaster layer 55 extends. To further improve the plaster grip, the plaster leg 17 also has a perforation, which cannot be seen in the figures and through which the plaster layer 55 extends when the plaster leg 17 has been plastered.

In the 3 shown embodiment differs from that in FIGS Figures 1 and 2 shown embodiment only in that a reinforcing fabric 57 is additionally arranged on the cleaning leg 17 . Therefore, and because of the smaller scale, not all are in the Figures 1 and 2 elements marked with reference symbols, but only the main structural elements of the plaster sealing strip 11 also in 3 provided with a reference number.

The reinforcement fabric 57 extends parallel to the plaster leg 17 and is partly in contact with its plastering surface 53, where it is connected to the plaster leg 17, in particular sewn, glued or welded thereto. The rest of the reinforcement fabric 57 , by far the greater part, extends beyond the plaster leg 17 . Due to the arrangement of the reinforcement fabric 57 on the cleaning leg 17, the reinforcement fabric 57 can be folded together with the cleaning leg 17. in the in 3 The storage position shown is that the reinforcement fabric 57 is aligned parallel to the base leg 15 together with the cleaning leg 17 . In the installed position of the cleaning leg 17 , the reinforcing fabric 57 extends away from the base leg 15 in an extension of the cleaning leg 17 , at least essentially perpendicularly to the base leg 15 . As a result, the reinforcement fabric 57 can then be applied together with the plaster leg 17 to the wall surface 31 of the building wall 27 and plastered in. The meshes of the reinforcement fabric 57 are advantageously large enough for the plaster to penetrate easily, so that the reinforcement fabric 57 contributes to the reliable embedding of the plaster sealing strip 11 in the plaster layer 55 .

The sealing plaster strip 11 according to the invention can thus completely and reliably meet all the requirements for a sealing plaster strip and can still be folded up compactly. In particular, the fact that the plaster sealing strip 11 can be rolled up in no way impairs its function in the assembled state. In addition, the joint sealing tape 47 can advantageously be kept in a precompressed state precisely by being rolled up, so that there is the additional advantage that separate means for holding the joint sealing tape 47 in a precompressed state can be dispensed with.
