Plaster sealing strip

Description

[0001] The invention relates to a plaster sealing strip for the structural connection of a building element, in particular a window, a door, a roller shutter box or the like, to a building wall.

[0002] Plaster sealing strips are used to seal joints formed between a building element and parts of a structure, such as a building wall, for example, between the frame of a window or door and the adjoining masonry. Plaster sealing strips of the type mentioned above are also used at transitions between differently designed wall or facade sections, such as the transition point between wood paneling and a plastered facade. Accordingly, facade elements, wall cladding elements, panels, and the like also constitute building elements within the meaning of the present disclosure. Apart from their sealing effect, plaster sealing strips ensure a visually appealing finish to a layer of plaster applied to the building wall.

[0003] To seal a joint between the building element and the building wall, the plaster sealing strip can be inserted at least partially into this joint. For stable attachment of the plaster sealing strip and / or to reinforce a corner edge at the transition from the building wall to the joint, it is also advantageous to at least partially plaster the plaster sealing strip into 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 in particular be designed as a thermal insulation composite system, so that the plaster sealing strip is attached to the thermal insulation of the building wall and plastered in. To attach the plaster sealing strip, it is therefore expedient to provide structures on the plaster sealing strip that enable stable plastering.

[0004] A plaster sealing strip is typically elongated and can extend over several meters. For example, a plaster sealing strip can be around 2.5 m or 3 m long. This can make a plaster sealing strip relatively bulky, which can make handling difficult. This also results in special requirements for the storage and transport of plaster sealing strips. Storage and transport could be simplified by making the plaster sealing strip less bulky. However, the typical structure of a plaster sealing strip, which (viewed in cross-section) usually has several sections aligned at an angle to one another, in particular a plastering leg for the aforementioned plastering, prevents the plaster sealing strip from being flexible. In principle, the plastering leg could be omitted or made very short.However, this would impair the arrangement and fastening of the plaster sealing strip to the building wall.

[0005] DE 20 2008 011 782 U1 discloses an edge profile comprising a fastening leg and a closing leg that can be folded together. In the folded position, it is flexible in the longitudinal direction, allowing the edge profile to be rolled up longitudinally. AT 006 819 U1 describes a reveal connection profile with an outer leg and a sealing leg flexibly connected thereto, wherein the sealing leg has fastening means, such as a sealing strip, on the component side. A reveal connection profile with the features of the preamble of claim 1 is known from DE 20 2006 009 790 U1.

[0006] It is an object of the invention to provide a plaster sealing strip which can be arranged and fastened particularly reliably, in particular to the building wall, for the structural connection of a building element to a building wall and is comparatively easy to handle, in particular can be stored and transported in a compact manner.

[0007] The object is achieved by a plaster sealing strip with the features of claim 1. Advantageous embodiments of the invention emerge from the subclaims, the present description and the figures.

[0008] The plaster sealing strip according to the invention for the structural connection of a building element, in particular a window or a door, to a building wall has a profile body comprising a base leg for fastening to the building element and / or the building wall, as well as a plaster leg for plastering onto 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 PVC.

[0009] The profile body advantageously has an elongated shape and preferably has an at least substantially constant cross-section along its entire longitudinal extent. At least in one installation configuration, i.e., in a state assumed by the plaster sealing strip during and after installation on the structural element and the building wall, the longitudinal extent has a straight course. As will be explained below, in other configurations of the plaster sealing strip, the profile body can also extend along a curved course. The cross-section at a specific point along the course is defined perpendicular to the direction of the course at the respective point.Deviations from the constant cross-section can be limited in particular 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 profiling, for example ribs, notches and / or knobs, to improve the plaster grip.

[0010] The base leg and the plaster leg are each flat as legs of the profile body. In relation to the cross-section of the profile body, the legs correspond to straight sections that preferably have an at least substantially constant thickness. Deviations from the constant thickness can be limited in particular to the respective leg, in particular the plaster leg, having perforations and / or other openings and / or surface profiling, for example grooves, notches and / or knobs, to improve the plaster's adhesion. When reference is made below to the orientation or extension of a respective leg (or a comparable section of the plaster sealing strip), this is to be understood in relation to the course of the straight section of the cross-section of the profile body corresponding to the leg.

[0011] The base leg serves for fastening to the building element and / or the building wall, as the plaster sealing strip is designed to be fastened to the building element and / or the building wall by means of the base leg. Preferably, the base leg is connected at least to the building element, whereby this connection may in particular comprise gluing. The base leg may also be connected to both the building element and the building wall simultaneously. In particular, this case the connection can be force-locking (in addition to another type of connection, such as gluing, or exclusively), in particular by at least part of the base leg, for example the fastening section of the base leg described below, being clamped between the building element and the building wall.

[0012] The plastering leg is intended for plastering onto the building wall in that the plastering sealing strip is designed so that it is arranged with the plastering leg on the building wall and the plastering leg is plastered onto the building wall so that the plastering leg is embedded in a layer of plaster applied to the building wall. In this respect, the plastering leg also contributes to the attachment of the plastering sealing strip to the building wall. As a rule, however, the plastering leg is plastered in later than the attachment of the base leg to the structural element and / or the building wall. To ensure particularly stable embedding of the plastering leg in the plaster, the plastering leg preferably has perforations through which the plaster can penetrate the plastering leg during plastering. In addition, the adhesion of the plaster to the plastering leg can be improved by the plastering leg having a surface profile on at least one side, preferably on both sides, which improves the plaster's grip.

[0013] The length of the base leg (i.e. the extension of the base leg transverse 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, regardless of the depth of the joint, does not need to be particularly large, since it is more important that the plaster sealing strip seals the joint reliably than that it extends particularly deeply into the joint. In contrast, a great length is advantageous for the plaster leg (i.e. the extension of the plaster leg transverse to the longitudinal extension of the profile body) with regard to long-term stable fastening of the plaster sealing strip to the building wall. It is therefore preferred if the plaster leg is at least not less long, and preferably more long, than the base leg.

[0014] According to the invention, the cleaning leg is coupled to the base leg in an articulated manner, advantageously in such a way that it can be folded between an installed position in which it is oriented at least substantially perpendicular to the base leg, and a storage position in which it is oriented at least substantially parallel to the base leg. Preferably, the orientation of the cleaning leg in the installed position deviates from an orientation perpendicular to the base leg, and the orientation of the cleaning leg in the storage position deviates from an orientation parallel to the base leg, in each case by a maximum of 20°, preferably by a maximum of 10°, in particular by a maximum of 5°.

[0015] The installation position of the plastering leg corresponds to the installation configuration of the plaster sealing strip in which it is mounted. Thus, when the plastering leg is in the installed position, the plaster sealing strip can have a structure that, 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 plastering leg to the base leg, namely, in particular, by folding the plastering leg from the installed position into the storage position.

[0016] The articulated coupling preferably occurs directly between the two legs (the base leg and the cleaning leg). In this case, the cleaning leg can, in particular, meet one of two opposite side surfaces of the base leg with one of its two ends transverse to the longitudinal extension of the profile body. Along the area of ​​this contact, 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 that is aligned parallel to the longitudinal extension of the profile body and runs through the aforementioned end of the cleaning leg's extension.

[0017] In the installed position, the cleaning leg can protrude perpendicularly from the base leg and thus form at least substantially a T-shape with the base leg. From this installed position, the cleaning leg can be folded by approximately 90° relative to the base leg into the storage position, in which it is then parallel to the base leg and preferably at least partially rests against the base leg. Preferably, the cleaning leg does not change its shape when folded over, but rather has the same shape (in cross-section) in both the installed position and the storage position, in particular a straight profile. The base leg also preferably does not change when the cleaning leg is folded over, but rather has the same shape (in cross-section), in particular a straight profile, in both the installed position and the storage position of the cleaning leg.

[0018] According to the invention, the plaster sealing strip can be rolled up when the plastering leg is in the storage position. This is made possible in particular by the parallel arrangement of the plastering leg and the base leg in the storage position. In other words, the plaster sealing strip is designed, in particular with regard to its structure and material, to be rolled up when the plastering leg is in the storage position. In the rolled-up state, the profile body no longer has a straight course along its longitudinal extent, but is wound in a spiral course around an axis perpendicular to the longitudinal extent and parallel to the extension (related to the cross-section) of the base leg, so that the plaster sealing strip (except at end sections of its longitudinal extent) rests with its underside on the top side of the next winding or with its top side on the underside 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 said axis, while the upper side of the plaster sealing strip (or an upper side of the base leg) is aligned radially in the opposite direction.

[0019] The roll-up capability is not limited to the two legs, but the plaster sealing strip can be rolled up as a whole, including any additional legs and / or other sections of the plaster sealing strip and / or elements provided on the plaster sealing strip, such as the holding means described further below. In order not to impair the roll-up capability, however, preferably no other section of the plaster sealing strip and no element provided on the plaster sealing strip that is not aligned at least substantially parallel to the base leg in the storage position of the plaster leg has a greater extension transverse to the longitudinal extension of the profile body than the base leg or the plaster leg. In particular, the plaster sealing strip preferably does not have any structures that protrude further from the base leg perpendicular to the base leg than the plaster leg in its installed position.

[0020] As far as the material of the plaster sealing strip, especially the base leg and the profile leg, is concerned, rollability can be supported by choosing a material with a sufficiently high modulus of elasticity. PVC is particularly suitable for this. However, rollability depends not only on the material properties, but also on the material thickness. Thus, many different materials can be considered for the plaster sealing strip due to their respective elasticity. In particular, different materials can be used for different parts of the plaster sealing strip, e.g., different PVCs, which can preferably be coextruded. By specifying the material thickness of each part of the plaster sealing strip, the desired flexibility for rolling up can then be adjusted (at least within certain limits).

[0021] By using a suitable material and selecting an appropriate material thickness, the base leg and the plaster leg can be made just flexible enough to be advantageously rolled up. It is difficult to avoid them also exhibiting a comparatively high degree of flexibility with regard to bending about an axis parallel to the longitudinal extent of the profile body. However, the base leg and the plaster leg do not need to be particularly rigid in this direction, since during installation they are preferably arranged so that they rest against the building element or building wall and are thus 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.

[0022] When the plastering 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 particularly compactly, so that it can be stored and transported relatively easily. For example, in the rolled-up state, the plaster sealing strip can have an inner diameter in the order of several 100 mm, for example in the range of 300 mm to 1000 mm, in particular of approximately 500 mm or 750 mm, so that it can be stored and transported rolled up around a core with a diameter of, for example, 300 mm, 400 mm, 500 mm, 750 mm or 1000 mm.

[0023] Before installation or during installation, the plaster sealing strip is unrolled (it is also possible to unroll just a part of the plaster sealing strip that has the required length and then separate it from the rest) and the plastering leg is then folded out from its storage position into its installation position so that the plastering sealing strip assumes its installation configuration in which it can then be arranged, fastened and plastered in at the transition between the building element and the building wall. The inventive design of the plastering sealing strip enables, on the one hand, a reliable connection to the building wall by means of an advantageously long, plasterable plastering leg which, in the installed configuration, protrudes perpendicularly from the base leg, and, on the other hand, a space-saving arrangement of the plastering sealing strip in its storage configuration, in which the plastering leg lies parallel to the base leg, despite the long plastering leg.

[0024] According to an advantageous embodiment, the plastering leg is articulated to the base leg via a hinged connection made of a material that is softer than the material of the plastering leg and / or the base leg. The hinged connection can in particular be designed as a soft connection. A suitable material is, for example, soft PVC. Such a hinged connection can in particular be co-extruded with the plastering leg and / or the base leg. This simplifies the manufacture of the plastering sealing strip. With such an embodiment, the plastering leg and the base leg can be firmly connected to one another and yet still be foldable relative to one another. As already mentioned above in general for the plastering sealing strip or parts of the plastering sealing strip, the flexibility of the hinged connection can also be advantageously adjusted by selecting a material thickness that is suitably adapted to the elastic properties of the material.

[0025] 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 building element, wherein the plaster leg extends along this fastening section in the stored position. Said joint 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 building element, in particular a frame of the building element. The side surface of the building wall and the surface of the building element are preferably parallel to one another.

[0026] 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 received in the joint in the assembled state. The remaining part of the base leg can form a cover section of the base leg, with which the base leg protrudes from the joint in the assembled state. In other words, the plaster sealing strip can be designed to be inserted into a joint between the building wall and the building element with a fastening section of the base leg and to protrude from the joint with a cover section adjacent to the fastening section, in particular by the cover section protruding beyond the plane of a wall surface of the building wall onto which the plaster leg is plastered. The plaster leg can in this case be coupled to the base leg precisely along a transition between the fastening section and the cover section.Conversely, the base leg is divided along the coupling of the plaster leg into a fastening section with which the base leg is inserted into the joint and a cover section with which the base leg protrudes from the joint.

[0027] The surfaces of the fastening section (which are oriented 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 preferably has a surface profiling to improve the adhesion of the plaster, at least on the side on which the plaster leg is coupled to the base leg.

[0028] Since the cleaning leg extends along the fastening section in the storage position, the cleaning leg must, starting from the installed position in which it protrudes at least substantially perpendicularly from the base leg, be foldable at least in the direction of the fastening section into an orientation parallel to the base leg. In principle, the cleaning leg can also be foldable in the opposite direction into an orientation parallel to the base leg. However, this is not absolutely necessary. Rather, the foldability of the cleaning leg in this direction can also be restricted, so that from the installed position it can either not be folded in this direction at all or in any case not into a position parallel to the base leg, in which it would extend along the aforementioned cover section.The fact that the cleaning leg cannot be folded or can only be folded to a limited extent from the installed position in the direction away from the storage position can result, for example, from the fact that the cleaning leg has structures on its side facing away from the fastening section, such as the web described further below, which prevent the cleaning leg from being arranged parallel to the base leg along its cover section.

[0029] In particular, because the plaster leg is folded toward the side of the base leg that is inserted into the joint between the building wall and the structural element in the storage position, the plaster leg can also be pre-tensioned, at least slightly, against the building wall in the installed position by the articulated connection between the plaster leg and the base leg. This can further contribute to a reliable hold on the building wall.

[0030] According to a further advantageous embodiment, the plastering leg has a contact surface for contacting the building wall, in particular a wall surface of the building wall, and in the storage position, this contact surface rests against the base leg, in particular against the aforementioned fastening section of the base leg. In other words, the plastering sealing strip is designed to be arranged on the building wall with a contact surface of the plastering leg resting against a wall surface of the building wall, wherein the plastering leg rests against the base leg with this contact surface in the storage position. Depending on the length of the plastering leg, the plastering leg rests against the base leg with the entire contact surface or at least with part of the contact surface in the storage position.

[0031] 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 said joint between the building wall and the building element and can in particular be oriented perpendicular to the said wall surface of the building wall. In particular, the plaster sealing strip can be designed to be arranged on the building wall such that the contact surface of the plaster leg rests against the said wall surface of the building wall and the contact surface of the base leg rests against the said side surface of the building wall. The articulated connection between the plaster leg and the base leg is thus preferably arranged on an edge along which the wall surface and the side surface of the building wall meet.

[0032] A surface of the plaster leg facing opposite the aforementioned contact surface of the plaster leg can form a plastering surface designed to receive plaster. The plaster leg can thus be positioned with the contact surface adjacent to the building wall and subsequently plastered onto the building wall by applying plaster to the plastering surface. At least the plastering surface, and possibly also the contact surface of the plaster leg, can have the aforementioned surface profiling, particularly in the form of ribs, notches, and / or knobs, to improve plaster adhesion.

[0033] According to a further advantageous embodiment, the plastering leg has a plastering surface which, in the storage position, points away from the base leg and on which a web is formed which projects vertically from the plastering leg. This plastering surface is in particular the aforementioned plastering surface which is opposite the aforementioned contact surface of the plastering leg. The web which projects vertically from the plastering surface can contribute to good adhesion of plaster, particularly in a corner area between the plastering leg and the base leg. In addition, the outer edge of the web, which in cross-section corresponds to a free end of the web, can also serve as a removal edge for the application of plaster. Preferably, the web is comparatively short in order not to impair the ability of the plaster sealing strip to be rolled up. For example, the web can have a length (ieThe plaster leg should have a cross-sectional length of at most 10% of the length of the plaster leg. However, a short ridge can also serve as a leveling aid, for example, at least for a base coat and / or reinforcing plaster, onto which one or more additional plaster layers can be applied if necessary.

[0034] According to the invention, it is further provided that the base leg has an upper side, to which the plaster leg is coupled, and a lower side opposite the upper side, on which holding means for attaching the plaster sealing strip to the building element are provided. At least the underside of the base leg, and optionally also the upper side of the base leg, preferably has a smooth surface. The designation of the sides of the base leg as "upper side" and "lower side" serves only as a conceptual distinction 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 building element, whereby the upper side and lower side of the base leg are then also arranged vertically and are thus aligned in horizontal directions.

[0035] The aforementioned holding means can serve both to connect the base leg (and thus the entire plaster sealing strip) to the building element and to support the base leg in the joint. To connect the base leg to the building element, 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. However, an adhesive connection is not absolutely necessary for attaching the base leg to the building element; rather, the attachment can, for example, also be (exclusively or among other things) force-fitting. The base leg can be clamped in place when inserted into the joint between the building wall and the building element, in particular by the holding means or at least part of the holding means.

[0036] For this purpose, but also in general, it is advantageous if the retaining means are flexible, elastic, in particular stretchable or compressible and / or pliable. Such a design not only contributes to a force-fitting attachment of the base leg in the joint, but also ensures that the plaster sealing strip does not impair its ability to roll up. Furthermore, it allows for a certain degree of movement compensation, i.e., an adjustment of the plaster sealing strip to a change in the size of the joint, which may narrow or widen, particularly due to temperature.

[0037] Depending on the design of a respective holding means, the holding means can be integrally connected to the base leg, for example co-extruded with the base leg, or can be formed separately from the base leg and attached thereto, for example glued.

[0038] According to an advantageous embodiment, the holding means comprise (at least) two flexible spacers that protrude from the underside of the base leg and are oriented at an angle such that their distance from one another increases with increasing distance from the base leg. Because the spacers protrude from the base leg, they can, in particular, span the joint. The base leg can then, in particular, rest with the aforementioned contact surface against the aforementioned side surface of the building wall and, via the spacers, be supported on the surface of the structural element that borders the joint on the opposite side.

[0039] One of the two spacers can, for example, be arranged at one end of the base leg's extension, namely the end with which the base leg is inserted into the joint. The other spacer can be arranged in particular in the area of ​​the coupling of the plaster leg to the base leg, namely in particular directly opposite this coupling. In this respect, the two spacers can at least essentially flank the aforementioned fastening section of the base leg, i.e., be arranged at opposite ends of the fastening section.

[0040] Preferably, both spacers are coextruded with the base leg.

[0041] Due to the flexibility of the spacers, the plaster sealing strip can be clamped into the joint using the fastening section of the base leg, which is also facilitated by the angled position of the spacers. The spacers can each extend from the base leg in a direction that forms an angle with the extension of the base leg, preferably in the range between 50° and 80°, in particular approximately 65°.

[0042] According to the invention, the holding means comprise a pre-compressed or compressible joint sealing tape that is fastened to the aforementioned 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 building element, into which the plaster sealing strip is inserted with at least part of its base leg. The joint sealing tape can in particular be designed as a so-called compression tape. In addition, the joint sealing tape can be provided on one or both sides with an adhesive layer in order to be adhesively connected to the base leg, in particular to the aforementioned fastening section of the base leg, on the one hand, and to be adhesively connectable to the building element, on the other hand. In particular, it can be provided that the plaster sealing strip is glued to the building element via the joint sealing tape during installation.

[0043] According to a further advantageous embodiment, the joint sealing tape is arranged between the two said spacers, wherein the spacers have an extension perpendicular to the base leg which corresponds to a partially compressed extension of the joint sealing tape. The said extension of the spacers refers to their respective extension in a relaxed rest position, i.e. when they are not deformed (e.g. bent, compressed or expanded) by any external force acting on them, i.e. in particular when 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 sustaining damage, namely preferably compressed by at least 2 mm and / or expanded by at least 3.5 mm.In this way, good compensation for movement can be ensured when the joint increases or decreases due to temperature.

[0044] According to a further advantageous embodiment, in a storage configuration of the plaster sealing strip, in particular in the storage configuration described above, the plaster leg is in the storage position and the plaster sealing strip is rolled up in such a way that the joint sealing tape is thereby held in a pre-compressed state. In this pre-compressed state, the joint sealing tape is particularly more strongly compressed than in the aforementioned partially compressed state. 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. Only after the plaster sealing strip has been unrolled, which in particular only occurs during installation, can the joint sealing tape then expand independently.By designing the plaster sealing strip in this way, additional means that would otherwise be required to keep the joint sealing tape compressed can be dispensed with.

[0045] According to a further advantageous embodiment, the plaster sealing strip comprises a flexible cover lip which protrudes from the base leg and is oriented obliquely such that it extends beyond the base leg in a direction parallel to the base leg. The cover lip can also be considered part of the aforementioned holding means, since it contributes to supporting the base leg on the structural element. Furthermore, the cover lip can protrude in particular from the aforementioned underside of the base leg, namely preferably from an edge of this underside. The direction in which the cover lip extends from the base leg encloses an angle with the extension of the base leg, which angle is preferably in the range between 50° and 80° and can in particular be approximately 65°.

[0046] 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. Unlike the spacers mentioned, the cover lip is preferably not provided on the fastening section, but on the cover section of the base leg and is therefore arranged outside the joint when the plaster sealing strip is in the installed state. Furthermore, the cover lip preferably extends further perpendicular to the base leg and is thinner than the two spacers mentioned, so that when the plaster sealing strip is in the installed state, it is bent more strongly by the building element than the spacers. This allows a free end of the cover lip to rest against the building element in the installed state. In addition, the cover lip extends away from the joint beyond the base leg so that it conceals the joint from the outside.In this way, the cover lip can create a curved, flush, and virtually seamless transition between the building wall and the structural element. Furthermore, the cover lip also contributes to sealing the joint.

[0047] According to a further advantageous embodiment, a reinforcing mesh is attached to the plaster leg, which, in the installed position, extends beyond the plaster leg in a direction away from the base leg. The reinforcing mesh can be sewn, glued, or welded to the plaster leg, for example. Such a reinforcing mesh allows the plaster sealing strip to be plastered over a larger area to the building wall. Due to its design as a mesh whose meshes allow plaster to penetrate, the reinforcing mesh can be embedded into the plaster particularly reliably and easily.

[0048] According to a further advantageous embodiment, the plaster sealing strip comprises a tear-off tab which is connected to the base leg, in particular to the aforementioned cover section of the base leg, via a predetermined breaking point. The tear-off tab can be connected to the base leg, in particular at an end of the base leg opposite the aforementioned fastening section, via the predetermined breaking point. The tear-off tab is preferably arranged as an extension of the base leg, such that the tear-off tab and the base leg lie at least substantially in one plane. Such a tear-off tab can serve to attach a protective film, which can be used to protect the building element from becoming soiled with plaster when the building wall is plastered. 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.

[0049] 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 constriction and / or a perforation. Alternatively or additionally, the predetermined breaking point can be formed by a section of a material that is softer than the material of the tear-off tab and the base leg. The tear-off tab, the predetermined breaking point, and the base leg can be coextruded.

[0050] In the following, the invention is further explained with reference to the figures merely by way of example. Fig. 1 shows a cross-sectional view of an embodiment of a plaster sealing strip according to the invention in an installed configuration in which the plastering leg of the plaster sealing strip is in its installed position. Fig. 2 shows a cross-sectional view of the same embodiment in a state in which the plastering leg of the plaster sealing strip is in its storage position. Fig. 3 shows a cross-sectional view of another embodiment of a plaster sealing strip according to the invention, with the plastering leg again shown in its storage position.

[0051] In the figures, a plaster sealing strip 11 according to the invention is shown in cross section. Fig. 1 and 2 shown embodiment and the one in Fig. 3The embodiments shown are largely identical in design. 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 substantially constant cross-section along a longitudinal extension that runs perpendicularly through the image plane of the figures. The base leg 15 and the plaster 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 both are made of the same material, namely PVC.

[0052] At one end of its extension, the cleaning leg 17 is hingedly coupled to an upper side 21 of the base leg 15 via a hinged connection 19. The hinged 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 17 are formed. Due to the hinged connection, the cleaning leg 17 is foldable 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 perpendicular to the base leg 15 and which it can Fig. 1 on the other hand, the cleaning leg 17 can be folded from this installation position into a storage position in which it is aligned at least substantially parallel to the base leg 15 and which it Fig. 2 occupies.

[0053] The articulated connection 19 divides the base leg 15 into a fastening section 23 and a cover section 25. The plaster sealing strip 11 is designed to be inserted, with the fastening section 23 of the base leg 15, into a joint 26 between a building wall 27, in particular a thermal insulation provided as part of this building wall 27, and a building element 29, which can in particular be a window or a door, and to be applied with the plastering 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.

[0054] In its storage position, the cleaning leg 17 is folded relative to its installed position in the direction of the fastening section 23 of the base leg 15 and therefore extends from the articulated connection 19 along the fastening section 23. Due to its length, the cleaning leg 17 projects beyond the base leg 15 (cf. Fig. 2 ).

[0055] At the end of the base leg 15 pointing in the opposite direction, a tear-off tab 35 is connected to the base leg 15 via a predetermined breaking point 33. The tear-off tab 35 lies essentially in the same plane as the base leg 15 and is thus arranged as an extension thereof. The tear-off tab 35 is made of the same material as the base leg 15 and serves to attach 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 during plastering. After assembly, the tear-off tab 35 with the protective film can be severed from the base leg 15 along the predetermined breaking point 33.

[0056] As in Fig. 2As can be seen, the entire plaster sealing strip 11 is largely flat when the plastering leg 17 is in its storage position, since the base leg 15 and the tear-off tab 35 lie essentially in one plane and the plastering leg 17 lies directly adjacent to the base leg 15. As a result of this, and through the selection of a sufficiently elastic material for the base leg 15, the plastering leg 17 and the tear-off tab 35, the plastering sealing strip 11 according to the invention can be rolled up about an axis that is parallel to the image plane of the figures as well as to the base leg 15 and the plastering leg 17. This makes it possible to store and transport the plastering sealing strip 11 in a particularly compact storage configuration, in which the plastering leg 17 is folded into the storage position and the entire plaster sealing strip 11 is rolled up.

[0057] For assembly, the rolled-up plaster sealing strip 11 can be unrolled and then the plaster leg 17 can be folded out into the installed 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, in the region of the fastening section 23, rests on a side surface 39 of the building wall 27 that laterally borders the joint 26, and the plaster leg 17 rests with a contact surface 41 on the wall surface 31 of the building wall 27 that is perpendicular to the side surface 39. The articulated connection 19 is thus arranged essentially along an edge of the building wall 27 at which the wall surface 31 and the side surface 39 of the building wall 27 meet.

[0058] During assembly, the plaster sealing strip 11 is also fastened to the structural element 29. For this purpose, holding means are provided on a bottom side 43 of the base leg 15 opposite the top side 21, which holding means comprise two flexible spacers 45 and a joint sealing strip 47. The two spacers 45 are arranged at opposite ends of the fastening section 23 and protrude obliquely from the bottom side 43 of the base leg 15 such that their distance from one another increases with increasing distance from the base leg 15. The spacers are so flexible that they can be further expanded by insertion into the joint 26, thereby reliably supporting the base leg 15 in the joint 26 on the structural element 29. In this way, the base leg 15 is force-fitted in the joint.

[0059] The joint sealing tape 47 is arranged between the two spacers 45. While the spacers 45 are coextruded with the base leg 15, but are made of a softer material than the material of the base leg 15, the joint sealing tape 47 is designed as a double-sided adhesive foam tape and is adhered to the underside 43 of the base leg 15. With its side facing away from the base leg 15, the joint sealing tape 47 can be adhered to the structural element 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 a thickness such 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.

[0060] Furthermore, at the end of the base leg 15, to which the tear-off tab 35 is connected via the predetermined breaking point 33, there is arranged a cover lip 49 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, due to its arrangement at this end, extends beyond the extent of the base leg 15. As a result, the cover lip 49 protrudes beyond the base leg 15 and, when the tear-off tab 35 is severed, 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 lies flush against the building element 29 and forms a largely continuous, curved transition from the building wall 27 to the building element 29.

[0061] In the figures, the spacers 45, the joint sealing strip 47 and the cover lip 49 are each shown in the form they take without the influence of an external force. Fig. 1 It therefore appears as if these elements spatially overlap the component 29. In fact, however, they are deformed during assembly by the component 29, whereby the joint sealing strip 47 is compressed more strongly than in the form shown and the spacers 45 and the cover lip 49 are each oriented in a direction away from the joint sealing strip 47 compared to the direction shown in Fig. 1 shown shape are deformed, in particular bent, so that they extend only to the surface of the component 29.

[0062] Even when the plaster sealing strip 11 is rolled up in its storage configuration, the spacers 45, the joint sealing tape 47 and the cover lip 49 can be compressed between windings of the rolled up plaster sealing strip 11 and thereby be compressed in a similar manner compared to the Fig. 2 shown. In particular, the rolling up keeps the joint sealing strip 47 between the windings in a pre-compressed state. Due to their deformability and their comparatively small extension perpendicular to the extension of the base leg 15, the spacers 45, the joint sealing strip 47, and the cover lip 49 do not prevent the plaster sealing strip 11 from being rolled up.

[0063] 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 plastering leg 17 is in its storage position, a web 51 extends perpendicular to the base leg 15 in a direction away from the base leg 15. The plastering leg 17 has this web 51 on a plastering surface 53 opposite the aforementioned contact surface 41. The web 51 projects perpendicularly from this plastering surface 53, the web 51 having a comparatively small extension, which is in particular less than the respective extension of the spacers 45, the joint sealing strip 47 and the cover lip 49 perpendicular to the base leg 15 and amounts to less than 10% of the extension of the plastering leg 17.

[0064] The web 51 is provided near the hinge connection 19, in particular within the first quarter of the extension of the plaster leg 17, starting from the end of the plaster 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 this way, the web 51 contributes to the stability of the plaster layer 55 in the region of the transition between the building wall 27 and the building element 29.

[0065] Furthermore, the adhesion of the plaster to 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. These ribs are arranged parallel to the longitudinal extent of the profile body 13 and regularly spaced from one another. The upper side 21 of the base leg 15 also has a corresponding surface profile in the area of ​​the aforementioned cover section 25 of the base leg 15, up to which the plaster layer 55 extends. To further improve the adhesion of the plaster, the plaster leg 17 also has a perforation, which is not visible in the figures and through which the plaster layer 55 extends when the plaster leg 17 is plastered.

[0066] The Fig. 3 The embodiment shown differs from that shown in the Fig. 1 and 2shown embodiment only in that a reinforcing mesh 57 is additionally arranged on the plaster leg 17. Therefore and because of the smaller scale of the illustration, not all of the Fig. 1 and 2 elements marked with reference numerals, but only the main structural elements of the plaster sealing strip 11 also in Fig. 3 provided with a reference symbol.

[0067] The reinforcement mesh 57 extends parallel to the plaster leg 17 and partially rests against its plastering surface 53, where it is connected to the plaster leg 17, in particular sewn, glued, or welded thereto. The remaining, by far predominant part of the reinforcement mesh 57 extends beyond the plaster leg 17. Due to the arrangement of the reinforcement mesh 57 on the plaster leg 17, the reinforcement mesh 57 can be folded together with the plaster leg 17. In the Fig. 3In the storage position shown, the reinforcing mesh 57 is therefore aligned together with the plaster leg 17 parallel to the base leg 15. In the installed position of the plaster leg 17, however, the reinforcing mesh 57 extends away from the plaster leg 17, at least substantially perpendicular to the base leg 15. As a result, the reinforcing mesh 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 reinforcing mesh 57 are advantageously large enough that they can be easily penetrated by the plaster, so that the reinforcing mesh 57 contributes to a reliable embedding of the plaster sealing strip 11 in the plaster layer 55.

[0068] The plaster sealing strip 11 according to the invention can thus fully and reliably meet all the requirements for a plaster sealing strip while still being compactly collapsible. In particular, the rollability of the plaster sealing strip 11 does not impair its function in the installed state in any way. Furthermore, the joint sealing tape 47 can advantageously be held in a pre-compressed state precisely by rolling it up, resulting in the additional advantage that separate means for holding the joint sealing tape 47 in a pre-compressed state can be dispensed with.
