The base profile has a profile body extending in a first longitudinal direction, which comprises a base leg oriented along a base direction for fastening to the building element and / or to the building wall and a plaster leg for plastering into a base plaster layer on the building wall, wherein the plaster leg protrudes from the base leg in a normal direction oriented at least substantially perpendicular to the base direction. The additional profile has a profile body extending in a second longitudinal direction, which comprises a plaster leg for plastering into an additional plaster layer on the base plaster layer.It is provided that the base profile has a coupling extension and the additional profile has a coupling receptacle or, conversely, the base profile has a coupling receptacle and the additional profile has a coupling extension, wherein the base profile and the additional profile are designed to be coupled to one another by inserting the coupling extension into the coupling receptacle in such a way that the cleaning leg of the base profile and the cleaning leg of the additional profile are arranged at a distance from one another and are aligned at least substantially parallel to one another.

Description

[0001] The invention relates to a plaster sealing strip for the connection of a building element, in particular a window, a door, a roller shutter box or the like, to a building wall. Plaster sealing strips with the features of the preamble of claim 1 and with the features of the preamble of claim 4 are known from DE 298 22 615 U1.

[0002] Plaster sealing strips are generally used to seal joints formed between a building element and parts of a building structure, such as a 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 at the junction 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 this disclosure. Apart from their sealing effect, plaster sealing strips provide an aesthetically pleasing finish to a plaster layer 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 a stable fastening 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 embed the plaster sealing strip, at least partially, in the building wall, i.e., in a layer of plaster applied to a wall surface of the building wall. The building wall can be a monolithic masonry structure. However, the building wall can also be constructed as an external thermal insulation composite system (ETICS), in which case the plaster sealing strip is attached to the thermal insulation of the building wall and embedded in the plaster. For fastening the plaster sealing strip, it is advisable to provide structures on the plaster sealing strip that allow for stable embedding in the plaster.

[0004] Especially when the building wall is a monolithic masonry structure, it can often be advantageous to use (ultra-)lightweight plasters for the initial plastering. These are applied relatively thickly and additionally reinforced with a full-surface mesh before the application of a topcoat. However, for other reasons as well, it can be beneficial to first apply a relatively thick base coat of plaster to a building wall, onto which one or more further coats of plaster are then applied. These can be considered a supplementary plaster layer, in which reinforcing mesh is advantageously embedded, particularly in the lowest of the aforementioned additional plaster layers. Conventional plaster stop beads are not specifically designed for such thick-layer plaster systems.In particular, conventional plaster sealing strips do not provide support for the application of one or more further plaster layers on a comparatively thick base coat.

[0005] It is an object of the invention to provide a plaster sealing strip for the connection of a building element to a building wall, which simplifies the application of a comparatively thick base coat of plaster to the building wall as well as an additional coat of plaster applied to the base coat.

[0006] The problem is solved by a plaster sealing strip with the features of claim 1 and by a plaster sealing strip with the features of claim 4. Advantageous embodiments of the invention will become apparent from the dependent claims, the present description and the figures.

[0007] The plaster sealing strip according to the invention for connecting a building element, in particular a window or door, to a building wall comprises a base profile and an additional profile. The base profile and the additional profile are designed separately, i.e., as two fundamentally independent components, and in particular, manufactured separately from one another. The plaster sealing strip is therefore designed in at least two parts. In particular, the plaster sealing strip can consist of the base profile and the additional profile, i.e., it can not include any further separate components.

[0008] According to the invention, the base profile comprises a profile body extending in a first longitudinal direction, which includes a base leg aligned along a base direction for attachment to the building element and / or to the building wall, and a plaster leg for embedding in a base plaster layer on the building wall, wherein the plaster leg projects from the base leg in a normal direction oriented at least substantially perpendicular to the base direction. Both the base direction and the normal direction are preferably orthogonal to the aforementioned first longitudinal direction.

[0009] The base leg and the cleaning leg can have a thickness that is at least substantially constant along their respective paths with respect to the cross-section of the profile body of the base profile. This thickness can be, for example, at least 0.5 cm, in particular at least 0.8 cm, and / or at most 1.5 cm, in particular at most 1.2 cm. Furthermore, the base leg and the cleaning leg can each be formed by one or more planar sections of the profile body, each of which has a straight path with respect to the cross-section of the profile body. In particular, the cleaning leg can be formed entirely by a single planar section, so that its cross-section has a path that is at least substantially straight throughout. Since the cleaning leg projects in the normal direction from the base leg, it can extend entirely along this normal direction.

[0010] The base leg serves for attachment to the building element and / or the building wall, insofar as the base profile is designed to be attached to the building element and / or the building wall via the base leg. Preferably, the base leg is connected to the building element, and this connection may include, in particular, gluing. The base leg can also be connected to both the building element and the building wall simultaneously. In this case, in particular, the connection can be force-fit – either exclusively or in addition to another type of connection, such as gluing – by clamping at least part of the base leg between the building element and the building wall.

[0011] The plaster leg of the base profile is designed for embedding in the building wall. The base profile is constructed so that its plaster leg is positioned against the building wall (particularly with the plaster leg parallel to the building wall), and the plaster leg is then embedded in the base coat of plaster, thus securing it within the plaster layer. In this way, the plaster leg also contributes to the attachment of the plaster sealing strip to the building wall. However, the plaster leg is typically embedded later than the base leg is attached to the building element and / or the building wall. For particularly stable embedding of the plaster leg in the base coat, it preferably features numerous openings through which the plaster can penetrate the plaster leg during the embedding process.Furthermore, the adhesion of the plaster to the plaster leg can be improved by the plaster leg having a surface profile that improves the plaster's grip, at least on one side, preferably on both sides, for example in the form of ribs, notches and / or bumps.

[0012] That the base leg is aligned along the base direction can mean, in particular, that the base leg has its greatest extent perpendicular to the first longitudinal direction and / or that it runs largely or predominantly, at least substantially, parallel to the base direction. Along the base direction, the base leg can, for example, extend over a length of at least 10 cm, in particular at least 12 cm, preferably at least 15 cm. The base profile can be designed, in particular, to be plastered into the building wall with its plaster leg in such a way that the base direction points at least substantially perpendicularly away from the building wall.

[0013] The cleaning leg is angled relative to the base leg, as it projects in the aforementioned normal direction from the base leg, which is at least substantially perpendicular to the insertion direction. Along this normal direction, the cleaning leg can extend, for example, over a length of at least 15 cm, in particular at least 20 cm, preferably at least 25 cm. Furthermore, it is preferred that the cleaning leg has a greater length than the base leg.

[0014] The profile body of the base profile is preferably formed in one piece. In particular, the base leg and the cleaning leg of this profile body are not formed separately from each other, but rather constitute different sections of the profile body solely due to their respective structures, especially their spatial orientation, and their respective functions. For example, the profile body as a whole can be manufactured by extrusion. If the profile body is formed from several different materials, it can be manufactured, in particular, by co-extrusion. The base leg and the cleaning leg of the profile body preferably consist of the same material and merge seamlessly into one another.

[0015] According to the invention, the additional profile has a profile body extending in a second longitudinal direction, which includes a plaster leg for embedding in an additional plaster layer on the base plaster layer. The designation of these longitudinal directions as first longitudinal direction and second longitudinal direction serves only for conceptual differentiation and is not intended to imply any order or hierarchy, nor that the first longitudinal direction and the second longitudinal direction must necessarily be different from each other. Nor do they have to be similar to each other. As long as the base profile and the additional profile are not coupled to each other, the spatial orientation of the first longitudinal direction and the second longitudinal direction relative to each other is undefined.

[0016] The cleaning leg of the additional profile can be oriented along a direction orthogonal to the second longitudinal direction. Along this direction, the cleaning leg can extend, for example, over a length of at least 15 cm, in particular at least 20 cm, preferably at least 25 cm. Furthermore, the cleaning leg can have a thickness that is at least substantially constant along its respective course with respect to the cross-section of the profile body of the additional profile. This thickness can be, for example, at least 0.5 cm, in particular at least 0.8 cm, and / or at most 1.5 cm, in particular at most 1.2 cm. The cleaning leg can also be formed by one or more planar sections of the profile body, each of which has a straight course with respect to the cross-section of the profile body.In particular, the entire plaster leg can be formed by a single flat section, so that in cross-section it has a generally straight course.

[0017] The plaster leg of the additional profile is designed for embedding in the base coat of plaster. Specifically, the additional profile is designed so that its plaster leg is positioned against the base coat of plaster, where the plaster leg of the main profile is already embedded (in particular, parallel to the base coat). The plaster leg of the additional profile is then embedded in the aforementioned additional plaster layer, thus becoming embedded within the base coat. This additional plaster layer can be designed as a top coat, onto which no further plaster layers are applied. Alternatively, it can be designed for an additional top coat to be applied over the additional plaster layer.For particularly stable embedding of the plaster leg in the additional plaster layer, the plaster leg of the additional profile preferably has a large number of openings through which the plaster can penetrate the plaster leg during application. Furthermore, the adhesion of the plaster to the plaster leg can be improved by providing the plaster leg with a surface profile that enhances plaster adhesion, for example in the form of ribs, notches and / or studs, at least on one side, preferably on both sides.

[0018] The cleaning leg of the additional profile can be essentially identical to the cleaning leg of the base profile. In particular, the cleaning leg of the base profile and the cleaning leg of the additional profile can be identical, for example with regard to their external shape, dimensions, material, surface structure and / or the arrangement of openings through the respective cleaning leg.

[0019] Like the profile body of the base profile, the profile body of the additional profile is preferably formed in one piece, so that, in particular, the cleaning leg is not formed separately from the rest of the profile body, but rather constitutes a section of the profile body distinct from other sections solely due to its structure, especially its spatial orientation, and its function. The profile body of the additional profile can, for example, be manufactured as a whole by extrusion or, if it is formed from several different materials, by co-extrusion. The cleaning leg preferably comprises the same material as the rest of the profile body and transitions directly into the rest of the profile body, in particular into the cover leg of the profile body of the additional profile described below.

[0020] Perpendicular to the first and second longitudinal directions, the profile body of the base profile and the profile body of the additional profile can each have a cross-section that is at least substantially constant. Deviations from the constant cross-section can be limited, in particular, to the fact that at least parts of the respective profile body have openings and / or a surface profile to improve plaster adhesion. Along the longitudinal direction, the respective profile body can extend over several meters. For example, the profile body of the base profile and the profile body of the additional profile can each have a length of approximately 2.5 m or approximately 3 m. The profile bodies can each be made of a plastic or a metal, for example, sheet metal; preferably, the profile bodies are made of a plastic, such as PVC, in particular rigid PVC.

[0021] Furthermore, according to the invention, the basic profile (in particular the base leg of the basic profile) has a coupling extension and the additional profile (in particular the cleaning leg of the additional profile) has a coupling receptacle, or, conversely, the basic profile (in particular the base leg of the basic profile) has a coupling receptacle and the additional profile (in particular the cleaning leg of the additional profile) has a coupling extension. These two alternatives are not mutually exclusive. It is therefore also possible for the basic profile to have both a coupling extension and a coupling receptacle, and / or for the additional profile to have both a coupling extension and a coupling receptacle. Moreover, none of these cases are limited to exactly one coupling extension or exactly one coupling receptacle.Rather, the basic profile and the additional profile can each have several coupling extensions and / or several coupling receptacles.

[0022] Preferably, the number of coupling extensions and the number of coupling receptacles are equal, so that a corresponding number of pairings, each consisting of one coupling extension and one coupling receptacle, can be formed (including the pairing consisting of the aforementioned single coupling extension and the aforementioned single coupling receptacle), wherein the coupling extension and the coupling receptacle of each pairing are provided on different profiles. In other words, for each pairing, either the coupling extension is provided on the base profile and the coupling receptacle on the additional profile, or the coupling extension is provided on the additional profile and the coupling receptacle on the base profile.If the basic profile and the additional profile together have several coupling extensions and coupling receptacles, the features described below for one coupling extension and one coupling receptacle preferably also apply to the further coupling extensions and further coupling receptacles, in particular to the coupling extension and the coupling receptacle of each further pairing consisting of one coupling extension and one coupling receptacle.

[0023] Preferably, of the two coupling elements (i.e., the coupling extension and the coupling receptacle), one is formed on the base leg of the basic profile and the other on the cleaning leg of the additional profile.

[0024] According to the invention, the basic profile and the additional profile are designed to be coupled to each other by inserting the coupling extension into the coupling receptacle in such a way that the cleaning leg of the basic profile and the cleaning leg of the additional profile are arranged at a distance from each other and are aligned at least substantially parallel to each other.

[0025] By coupling the coupling extension (formed on one of the two profiles) and the coupling receptacle (formed on the other of the two profiles) (and optionally one or more further coupling extensions with their respective further coupling receptacles), the plaster sealing strip is brought into a coupled state in which the plaster legs of the two profiles are spaced apart from each other and aligned at least substantially parallel to each other. Preferably, the base profile and the additional profile are held in a defined orientation relative to each other (apart from any possible play) by the aforementioned coupling, in which the plaster legs are aligned at least substantially parallel to each other. Preferably, the deviation from an exactly parallel orientation is at most 15°, more preferably at most 10°, and particularly at most 5°.

[0026] When inserted into the coupling receptacle, the coupling extension can snap into place, as explained in more detail below. The coupling extension and the coupling receptacle can be designed such that, once inserted, the coupling extension cannot be removed (at least not without damaging at least part of the plaster sealing strip), making the coupling of the base profile and the additional profile irreversible. Alternatively, it can also be designed so that the coupling extension can be removed from the coupling receptacle after insertion, possibly by applying a certain amount of force to overcome a locking effect.

[0027] The coupling extension and the coupling receptacle each preferably extend along the first longitudinal direction and the second longitudinal direction, respectively (depending on which profile they are located on), and in particular over the entire length of the respective profile. The coupling extension can, for example, be designed as an elongated web section, which is preferably continuous in the respective longitudinal direction, but may also have interruptions. The coupling receptacle can, for example, be designed as an elongated groove into which the web section can be inserted to couple the base profile and the additional profile. The groove is also preferably continuous in the respective longitudinal direction, but may also have interruptions. The depth of the groove can correspond at least substantially to the height of the web section.By deeply engaging the coupling extension in the coupling receptacle, the base profile and the additional profile (and thus their cleaning legs) can be held particularly stably in a defined alignment relative to each other in the coupled state.

[0028] In the coupled state, the first longitudinal direction in which the base profile extends and the second longitudinal direction in which the additional profile extends are preferably parallel to each other, with this alignment advantageously resulting automatically from the coupling process by inserting the coupling extension into the coupling receptacle. It is therefore not necessary to precisely align the additional profile with the building wall. The insertion of the coupling extension into the coupling receptacle preferably occurs in a direction perpendicular to the longitudinal directions, which is particularly parallel to the aforementioned base direction or perpendicular to the aforementioned normal direction. Due to the parallel alignment of the plaster legs in the coupled state, both the plaster leg of the base profile and the plaster leg of the additional profile can extend along the normal direction in the coupled state.

[0029] The distance between the plaster leg of the base profile and the plaster leg of the additional profile in the coupled state is preferably at least 5 cm, more preferably at least 10 cm, and particularly at least 15 cm. This distance allows a base coat of plaster of appropriate thickness to be applied to the base profile mounted on the building wall, and only then is the additional profile coupled to the base profile. As a result of the coupling, the plaster leg of the additional profile can then rest at least substantially against the base coat. If, on the other hand, the additional profile were connected to the base profile from the outset, it would hinder the application of the base coat (especially if it is provided with reinforcing mesh).Due to the aforementioned coupling, the additional profile, unlike the basic profile, does not need to be carefully aligned with the building wall, as precise alignment of the additional profile results directly from the coupling with the already aligned basic profile.

[0030] Once the additional profile is securely attached to the base coat of plaster, a further layer of plaster can be applied, into which the plaster leg of the additional profile is embedded. This allows both the application of the base coat and the application of the further layer of plaster to be supported by either of the two profiles of the plaster sealing strip. Depending on the spacing of the plaster legs when coupled, the base coat can be relatively thick.

[0031] According to a first embodiment of the invention, the base profile has a tear-off tab which is connected to the base leg via a predetermined breaking point, wherein the coupling extension or coupling receptacle of the base profile (depending on which is provided on the base profile) is arranged relative to the predetermined breaking point in a direction opposite to the normal direction, preferably also in a direction opposite to the base direction.

[0032] The tear-off tab preferably extends along the base direction, in particular at least substantially in direct extension of the base leg or at least of the aforementioned spacer section of the base leg. The predetermined breaking point, via which the tear-off tab is connected to the base leg, can be located, in particular, at the aforementioned end of the spacer section furthest from the building. The predetermined breaking point can, for example, be formed by a section of reduced thickness, which, due to the smaller amount of material, has reduced stability compared to the base leg and the tear-off tab. Alternatively or additionally, the predetermined breaking point can be made of a different, in particular softer, material (e.g., flexible PVC) than the tear-off tab and the base leg. In this case, the base profile can be manufactured by co-extrusion.

[0033] The aforementioned arrangement of the coupling extension or coupling receptacle relative to the predetermined breaking point makes it possible, in particular, to ensure that the coupling extension or coupling receptacle is concealed by the tear-off tab when viewed from a direction opposite to the normal direction, and preferably also when viewed from a direction with portions both opposite to the normal direction and opposite to the base direction. In this way, when applying the base coat of plaster, the tear-off tab protects not only the respective component but also the coupling extension or coupling receptacle from contamination by the plaster. However, due to the aforementioned arrangement of the tear-off tab, the coupling of the additional profile to the base profile by the tear-off tab may be hindered.In particular, the tear-off tab can be arranged in such a way that it must be separated from the base profile along the predetermined breaking point before the coupling extension can be inserted into the coupling receptacle in order to couple the base profile and the additional profile together.

[0034] According to an advantageous embodiment of the first variant of the invention, the cleaning leg of the additional profile has a rear side on which the coupling extension or the coupling receptacle (depending on which is provided on the additional profile) is formed, and a front side opposite it (i.e. to the rear side), wherein the profile body of the additional profile comprises a cover leg which projects from the front of the cleaning leg of the additional profile.

[0035] The cover leg preferably projects from one of two ends of a longitudinal extension of the plaster leg of the additional profile (parallel to the normal direction in the coupled state), particularly from the end where the coupling extension or coupling receptacle is also located. Furthermore, the cover leg preferably projects at least substantially perpendicularly from the plaster leg. The additional profile can therefore have an L-shape, at least substantially (particularly excluding the coupling extension or coupling receptacle). However, the cover leg can also be inclined, in which case the plaster leg and the cover leg preferably meet at an obtuse angle.The length of the cover leg along the direction in which it projects from the cleaning leg can, for example, correspond to at most one-third, preferably at most one-quarter, and in particular at most one-fifth, of the length of the cleaning leg of the additional profile. For example, the cover leg can have a length of at most 8 cm, preferably at most 6 cm, and in particular at most 5 cm.

[0036] The cover leg of the additional profile can serve to laterally limit the additional plaster layer, particularly towards the building element. The plaster sealing strip is preferably designed so that, when the base profile and the additional profile are coupled and the plaster sealing strip is mounted on the building wall and the building element, a gap remains between the cover leg and the building element (to compensate for movement between the building wall and the building element). A free end of the cover leg (pointing away from the plaster leg) can also serve as a plaster edge for applying the additional plaster layer and / or for applying a topcoat plaster to the additional plaster layer.

[0037] According to a further advantageous embodiment of the first variant of the invention, the additional profile has a tear-off tab that is connected to the cover leg via a predetermined breaking point. The tear-off tab preferably extends along the same direction as the cover leg. In the coupled state, this direction can, in particular, correspond to the base direction. The tear-off tab can also extend in direct extension of the cover leg of the additional profile. The tear-off tab of the additional profile can, in particular, serve to protect the building element from contamination by plaster during the application of the additional plaster layer and to prevent plaster from entering the aforementioned joint between the cover leg and the building element.

[0038] The predetermined breaking point, where the tear-off tab is connected to the cover leg, can be located, in particular, at the aforementioned free end of the cover leg. The predetermined breaking point can, for example, be formed by a section of reduced thickness, which, due to the thinner material, has reduced stability compared to the cover leg and the tear-off tab. Alternatively or additionally, the predetermined breaking point can be made of a different, in particular softer, material (e.g., flexible PVC) than the tear-off tab and the cover leg. In this case, the additional profile can be manufactured by co-extrusion.

[0039] According to a second embodiment of the invention, the cleaning leg of the additional profile has a rear side on which the coupling extension or the coupling receptacle (depending on which is provided on the additional profile) is formed, and a front side opposite this (i.e., the rear side), wherein the profile body of the additional profile comprises a cover leg that projects from the front of the cleaning leg of the additional profile; furthermore, the additional profile has a tear-off tab that is connected to the cover leg via a predetermined breaking point. The preceding explanations relating to corresponding features of possible embodiments of the first embodiment of the invention apply mutatis mutandis to these features of the second embodiment of the invention. Unlike the first embodiment of the invention, in the second embodiment the base profile does not necessarily also have to have a tear-off tab.

[0040] The embodiments described below refer to both variants of the invention.

[0041] According to an advantageous embodiment, the base leg of the base profile comprises a spacer section extending along the base direction from an end closer to the building to an end further away from the building (opposite the end closer to the building with respect to the base direction), wherein the plaster leg of the base profile projects from the base leg (in the normal direction) at the end closer to the building, and the coupling extension or coupling receptacle of the base profile is arranged at the end further away from the building. The coupling extension or coupling receptacle is preferably arranged on a side of the base leg that points in the direction opposite to the normal direction. Thus, the coupling extension or coupling receptacle and the plaster leg of the base profile, which projects in the normal direction, are not only arranged at opposite ends of the spacer section of the base leg, but also on opposite sides of the base leg.

[0042] The designations of the ends of the distance section as near the building and far from the building primarily serve to conceptually distinguish between the two ends.

[0043] Whether they are actually close to or far from the building naturally depends on whether the plaster sealing strip is positioned against the building wall. However, the plaster sealing strip is designed to be positioned against the building wall, particularly with its base oriented perpendicular to the building wall, in such a way that the end of the spacer section closest to the building wall is closer than the end furthest from the building wall.

[0044] The spacer section preferably has a length of at least 5 cm, more preferably at least 10 cm, and particularly at least 12 cm, along the base direction. For example, the length can be approximately 15 cm. Furthermore, the spacer section can be designed as a flat section and have a cross-section that is at least substantially straight and parallel to the base direction. The spacer section can, in particular, correspond to that part of the base leg that connects the cleaning leg of the base profile to the coupling extension or coupling receptacle of the base profile. In principle, the spacer section can also correspond to the entire base leg.

[0045] According to an advantageous embodiment, the profile body of the base profile comprises a limiting section that projects from the end furthest from the building in the normal direction from the base leg. The limiting section thus projects from the base leg in the same direction as the plaster leg and has a distance from the plaster leg defined by the length of the spacer section. This allows the limiting section to define the plane to which the base coat of plaster is to extend from the building wall. For this reason, the limiting section can serve as a marker and also as a screeding aid for applying the base coat of plaster to the building wall in a suitable thickness. The limiting section is preferably significantly shorter (with respect to its extension along the normal direction) than the plaster leg of the base profile.For example, the length of the boundary section along the normal direction can be at most one-third, preferably at most one-quarter, and in particular at most one-fifth, of the length of the plaster leg along the normal direction. For example, the boundary section can have a length of at most 8 cm, preferably at most 6 cm, and in particular at most 5 cm.

[0046] According to a further advantageous embodiment, a reinforcing mesh is attached to the plaster leg of the additional profile, extending beyond the plaster leg of the additional profile. In the coupled state, the reinforcing mesh preferably extends in the normal direction beyond the plaster leg of the additional profile. Depending on the embodiment, a reinforcing mesh can also be attached to the plaster leg of the base profile, extending in the normal direction beyond the plaster leg of the base profile. Preferably, however, only the plaster leg of the additional profile has a reinforcing mesh.

[0047] The reinforcing mesh ensures reliable embedding of the additional profile in the additional plaster layer. Furthermore, particularly when using (ultra-)lightweight plaster for the base coat, it can be advantageous to provide the base coat with a full-surface mesh reinforcement by embedding one or more reinforcing meshes in the additional plaster layer across the entire plastered area. The reinforcing mesh attached to the plaster leg of the additional profile can form at least part of this reinforcement.

[0048] According to a further advantageous embodiment, the base leg of the base profile has a mounting surface that points in the opposite direction to the normal direction. This surface can, in particular, be a side surface of the aforementioned spacer section of the base leg. Preferably, the side surface is at least substantially planar (especially apart from any surface structure that may be provided), i.e., it lies in a plane, which can, in particular, be aligned parallel to the base direction and to the first longitudinal direction. The mounting surface can serve to connect the base profile to the component in order to attach and / or support the base profile to the component and / or to seal a gap between the mounting surface and the component.

[0049] According to an advantageous embodiment, one or more fastening means for attaching the base profile to the building element and / or one or more sealing means for sealing a gap between the base profile and the building element are provided on the mounting surface of the base leg. The fastening may also be limited to supporting the base profile against the building element.

[0050] The fastening means can be designed, in particular, as means for an adhesive bond and may, for example, comprise one or more adhesive tapes, preferably double-sided, preferably foam adhesive tapes. For example, the fastening means can comprise a first adhesive tape that is bonded on one side to the fastening surface and on the other side to an intermediate profile, preferably at least substantially planar, particularly strip-shaped, and a second adhesive tape that is bonded on one side to the intermediate profile and on the other side is designed for an adhesive bond with the component. Both the first and the second adhesive tapes are preferably foam adhesive tapes.The intermediate profile can be designed similarly to a leg of the basic profile or the additional profile, in particular having a similar thickness and / or being made of a similar material, in particular a plastic, for example a PVC.

[0051] Furthermore, a sealing membrane can extend between the fastening surface and the aforementioned intermediate profile as a sealing agent, which is preferably arranged in the base direction relative to the first adhesive tape (and thus further away from the building wall than the first adhesive tape) and whose length from the fastening surface to the intermediate profile is greater than the thickness of the first adhesive tape, wherein the first adhesive tape is preferably designed with regard to the respective adhesive force to detach from the fastening surface or the intermediate profile sooner than the second adhesive tape from the intermediate profile or the building element.In this way, if, for example, the joint between the building wall and the building element widens due to thermal expansion, the connection between the mounting surface of the base profile and the intermediate profile may detach via the first adhesive tape. However, the intermediate profile remains reliably connected to the building element via the second adhesive tape and also to the mounting surface of the base profile via the aforementioned membrane. Thus, despite the widening of the joint and the detachment of the first adhesive tape, no gap forms between the mounting surface and the intermediate profile; the entire space between the base profile and the building element remains sealed.

[0052] As an alternative (and also in addition) to a membrane, the sealant can also include a pre-compressed or compressible joint sealing tape (so-called compression tape). Such a joint sealing tape is typically designed to expand during or after installation to seal the space into which it is inserted (in this case, the gap between the mounting surface of the base leg of the base profile and the building element). The joint sealing tape can be provided with an adhesive layer on one or both sides, allowing it to be bonded to the mounting surface or at least bonded to it, and optionally bonded to the building element as well. In particular, it may be intended that the plaster sealing strip is bonded to the building element via the joint sealing tape during installation.The joint sealing tape can also contribute to the force-fit attachment of the base profile to the building element simply by expanding. In this respect, the joint sealing tape can serve simultaneously as a sealant and a fastener. Preferably, however, even if the sealant includes a joint sealing tape, the fasteners also comprise at least one adhesive tape, in particular foam adhesive tape.

[0053] However, not all fasteners and / or sealants need to be pre-installed on the plaster stop bead. In principle, one or more fasteners, or at least some of them, and / or one or more sealants, or at least some of them, can be added later. This applies particularly to joint sealing tape.

[0054] According to an advantageous embodiment, a recess is provided on the mounting surface of the base leg to accommodate one or more fasteners for attaching the base profile to the building element and / or one or more sealants for sealing a gap between the base profile and the building element. This recess can be formed, in particular, by the base profile having at least one support section that projects from the mounting surface in the opposite direction to the normal direction, so that the mounting surface cannot be approached closer than a certain minimum distance to the building element, defined by the length of the support section, and thus the aforementioned recess inevitably remains between the mounting surface and the building element. This recess is then laterally limited, in particular in the opposite direction to the base, by the support section.In the base direction, the free space is preferably bordered directly by the coupling extension or the coupling receptacle (depending on which is provided on the base profile).

[0055] The gap can be used, in particular, to accommodate a joint sealing tape of the type mentioned. The joint sealing tape can be inserted into the gap in a compressed state, especially after the base profile has been positioned on the building wall and, if necessary, attached to the building element using a fastener. The base profile is preferably already embedded in the base coat of plaster with its plaster flange; however, this is not absolutely necessary. After insertion into the gap, the joint sealing tape can expand to seal the space between the fastening surface and the building element.However, the joint sealing tape can also be positioned on the fastening surface from the outset, especially before the base profile has been arranged and, if necessary, attached to the building element, but initially kept in a pre-compressed state (e.g., by an enclosing film) and only released for expansion after the base profile has been attached to the building wall and / or the building element (e.g., by cutting or dissolving the film).

[0056] According to a further advantageous embodiment, locking means are provided on the coupling receptacle and on the coupling extension, wherein the locking means of the coupling receptacle (i.e. the locking means provided on the coupling receptacle) and the locking means of the coupling extension (i.e. the locking means provided on the coupling extension) interlock with respect to the direction of insertion when the coupling extension is inserted into the coupling receptacle, so that the base profile and the additional profile are positively secured against separation by the interlocking.

[0057] For example, the coupling extension can have a cross-sectional shape at its tip that is at least substantially circular, and the coupling receptacle can have a cross-sectional shape that is C-shaped, with an inner diameter that corresponds at least substantially to the outer diameter of the aforementioned circular shape. When inserting the coupling extension into the coupling receptacle, the ends of the C-shape must therefore be temporarily expanded and then (once the circular shape is completely enclosed within the C-shape) engage behind the C-shape in the direction of insertion, so that the coupling extension is positively secured in the coupling receptacle.

[0058] Furthermore, the locking means can, for example, comprise at least one locking projection on the one hand (on the coupling extension or the coupling receptacle) and at least one locking recess on the other hand (on the respective other of these two coupling elements), wherein the locking projection is elastic in such a way that it is deflected when the coupling extension is inserted into the coupling receptacle and, at the latest after the coupling extension has been completely inserted into the coupling receptacle, engages in the locking recess in a spring-back manner. This engagement occurs in particular in a direction transverse to the direction of insertion and thus corresponds with respect to the direction of insertion to the aforementioned engagement, which then positively secures the coupling extension against leaving the coupling receptacle in the opposite direction to the direction of insertion.

[0059] The aforementioned locking projection can be designed, in particular, as a locking tongue or in the manner of a barb or pawl. The locking recess can be essentially complementary to the locking projection. Furthermore, it is conceivable that several locking recesses are provided, arranged in a toothed configuration, with the locking projection engaging successively in each of these partial recesses when the coupling extension is inserted into the coupling receptacle. In this way, the coupling extension can be secured in the coupling receptacle at several different insertion depths, similar to a cable tie.

[0060] The invention will be further explained below using the figures as examples only. Figures 1 and 2 show the basic profile and the additional profile, respectively, of a first embodiment of a plaster sealing strip according to the invention. Figure 3 shows two alternative possibilities for the design of the coupling extension and the coupling receptacle of a plaster sealing strip according to the invention. Figure 4 shows the first embodiment of a plaster sealing strip according to the invention in the coupled state. Figure 5 shows a second embodiment of a plaster sealing strip according to the invention in the coupled state. Figures 6 to 9 show the first embodiment of a plaster sealing strip according to the invention in four different states.

[0061] The figures show various embodiments of the plaster sealing strips 11 according to the invention for connecting a building element to a building wall, each in cross-section. The plaster sealing strips 11 extend along a first or second longitudinal direction L1, L2, respectively, perpendicular to the plane of the figure and exhibit the cross-section shown at least substantially over their entire longitudinal extent. Elements of different embodiments that correspond to one another are marked with the same reference numeral.

[0062] In the Fig. 1, 2 and 4 Figures 6 to 9 each show at least parts of a first embodiment of a plaster sealing strip 11 according to the invention. Fig. 1Figure 1 shows a basic profile 13 of this plaster sealing strip 11, which comprises a profile body 15 extending along the first longitudinal direction L 1, which in turn has a base leg 17, a plaster leg 19, and a limiting section 21. The base leg 17 extends with at least a substantially straight course along a base direction B, which is oriented perpendicular to the first longitudinal direction L 1. A spacer section 23 of the base leg 17 extends from an end 25 near the building to an end 27 farther from the building, wherein, in the first embodiment, the spacer section 23 corresponds to the entire base leg 17.

[0063] At the end 25 closest to the building, the plaster leg 19 projects in a normal direction N from the base leg 17, oriented perpendicular to the base direction B and the first longitudinal extension L 1, while the boundary section 21 at the end 27 furthest from the building also projects in the normal direction N from the base leg 17. The length of the plaster leg 19 (along the normal direction N) is greater than the length of the base leg 23 (along the base direction B), while the length of the boundary section 21 (along the normal direction N) is less than the length of the base leg 23 (along the base direction B).

[0064] One side of the base leg 17 of the base profile 13, which points in the opposite direction to the normal direction N and is thus oriented opposite to the plaster leg 19 and the limiting section 21, forms a fastening surface 29 of the base leg 17, via which the base profile 13 is attached to the respective building element (in Fig. 1(not shown) can be attached. For this purpose, the base profile 13 in the first embodiment comprises a planar, at least substantially strip-shaped intermediate profile 31, which is aligned parallel to the base direction B. A first side surface of the intermediate profile 31 is connected to the mounting surface 29 via a first adhesive tape 33; a second adhesive tape 35 is affixed to a second side surface of the intermediate profile 31 opposite the first side surface, by means of which the intermediate profile 31 can be glued to the respective component.

[0065] The first adhesive tape 33 and the second adhesive tape 35 are both foam tapes. While the second adhesive tape 35 extends substantially over the entire extent of the intermediate profile 31 along the base direction B, the extent of the first adhesive tape 33 along the base direction B is shorter; in particular, it is less than half the extent of the intermediate profile 31 along the base direction B. This creates a gap between the fastening surface 29 and the intermediate profile 31, which, with respect to the base direction B, lies between the first adhesive tape 33 and the end 27 furthest from the building of the spacer section 23 of the base leg 17. This gap is spanned by a membrane 37, which is connected on one side to the fastening surface 29 and on the other side to the intermediate profile 31, and whose cross-sectional length is greater than the thickness (extent along the normal direction N) of the first adhesive tape 33.

[0066] Due to its shorter extension along the base direction B and / or the nature of the respective adhesive bond, the first adhesive tape 33 exhibits a lower adhesive strength than the second adhesive tape 35. Therefore, if the profile body 15 of the base profile 13 were to move away from the respective building element, for example due to thermal reasons, the connection between the mounting surface 29 and the intermediate profile 31 would detach, while the connection between the intermediate profile 31 and the building element would remain intact. However, the mounting surface 29 and the intermediate profile 31 would then advantageously remain connected to each other via the membrane 37, so that the joint between the base profile 13 and the building element would remain sealed. In this way, the plaster sealing strip 11 allows for movement compensation while still providing a reliable seal.

[0067] At the end 27 furthest from the building of the spacer section 23 of the base leg 17, a coupling receptacle 39 of the base profile 13 is formed. This coupling receptacle 39 is essentially designed as a groove extending along the first longitudinal direction L 1 and, in the first embodiment, having a C-shaped cross-section. The coupling receptacle 39 is formed on the side of the mounting surface 29 and is open in the base direction B (pointing away from the end 25 closest to the building).

[0068] The base profile 13 further comprises a tear-off tab 41, which is connected via a predetermined breaking point 43 to the end 27 furthest from the building of the spacer section 23 of the base leg 17 and is aligned parallel to the base direction B, so that it is arranged in direct extension of the base leg 17. The tear-off tab 41 can be detached from the profile body 15 of the base profile 13 along the predetermined breaking point 43.

[0069] The coupling receptacle 39 serves to couple the base profile 13 with a Fig. 2 The additional profile 45 shown separately comprises a profile body 47 extending in the second longitudinal direction L 2, which is in the coupled state of the plaster sealing strip 11 (i.e., when the basic profile 13 and the additional profile 45 are coupled together; see, e.g., Fig. 4 ) coincides with the first longitudinal direction L 1.

[0070] The profile body 47 of the additional profile 45 comprises a plaster leg 49, which is fundamentally similar in design to the plaster leg 19 of the basic profile 13 and extends with an at least substantially straight course along a direction perpendicular to the second longitudinal direction L 2. In the coupled state of the plaster sealing strip 11, this direction corresponds to the aforementioned normal direction N.

[0071] Furthermore, the profile body 47 of the additional profile 45 includes a cover leg 51, which, in the first embodiment, projects perpendicularly from one end of the plaster leg 49. When the base profile 13 and the additional profile 45 are coupled, the cover leg 51 projects from the plaster leg 49 in the base direction B. The length of the cover leg 51 is significantly shorter than that of the plaster leg 49 of the additional profile 45.

[0072] Similar to the basic profile 13, the additional profile 45 also has a tear-off tab 53, which is connected via a predetermined breaking point 55 to the cover leg 51, specifically to an end of the cover leg 51 spaced apart from the cleaning leg 49. The tear-off tab 53 is arranged in direct extension of the cover leg 51 and, in the coupled state, is therefore aligned parallel to the base direction B. The tear-off tab 53 can be separated from the profile body 47 of the additional profile 45 along the predetermined breaking point 55.

[0073] The cover leg 51 projects from a front face 57 of the cleaning leg 49 of the additional profile 45. A coupling extension 61 is formed on a rear face 59 of the cleaning leg 49 opposite this front face. This coupling extension is formed at least substantially perpendicular to the cleaning leg 49. In the first embodiment, the coupling extension 61 is designed as a rib projecting from the rear face 59, the free end of which has a circularly thickened cross-section. This makes the free end of the coupling extension 61 at least substantially complementary to the C-shape of the coupling receptacle 39. However, the diameter of the circular shape is slightly larger than the opening of the C-shape, so that when the coupling extension 61 is inserted into the coupling receptacle 39, the opening is temporarily widened, and after insertion, the circular shape engages behind it.In this way, the coupling extension 61 locks into the coupling receptacle 39 and is thus positively secured against leaving the coupling receptacle 39.

[0074] However, such a locking effect is not absolutely necessary, as the upper of the two in Fig. 3 The alternative possibilities shown for the design of the coupling receptacle 39 and the coupling extension 61 are illustrated, in which the coupling receptacle 39 has at least a substantial U-shape with straight legs and the coupling extension is designed as a flat web without a thickened free end. The lower of the two shown Fig. 3The alternative design shown is very similar to the one above and differs from it only in that the coupling receptacle 39 has internal teeth and the coupling extension 61 has complementary external teeth, which mesh when the coupling extension 61 is inserted into the coupling receptacle 39. The teeth are asymmetrical in each case such that when an attempt is made to pull the coupling extension 61 out of the coupling receptacle 39 in the opposite direction to which it was inserted, the tooth flanks of the internal teeth of the coupling receptacle 39 and the tooth flanks of the external teeth of the coupling extension 61, which are oriented perpendicular to this direction, are pressed together over a surface area, thus preventing the coupling extension 61 from being removed from the coupling receptacle 39.Therefore, this type of design of the coupling receptacle 39 and the coupling extension 61 allows for an irreversible coupling, whereas the coupling of the first embodiment can also be released.

[0075] In Fig. 4 are these in Fig. 1 basic profile 13 shown and the one in Fig. 2 The additional profile 45 of the first embodiment of a plaster sealing strip 11 according to the invention is shown in its coupled state. If the base profile 13, as in the first embodiment, has the aforementioned tear-off tab 41, this tab must first be separated from the profile body 15 at the predetermined breaking point 43 in order to couple the base profile 13 with the additional profile 45 by inserting the coupling extension 61 into the coupling receptacle 39. The tear-off tab 41 is then no longer part of the base profile 13 and is therefore in Fig. 4not shown. In the coupled state, the first longitudinal direction L1 and the second longitudinal direction L2 coincide; furthermore, the cleaning leg 19 of the base profile 13 and the cleaning leg 49 of the additional profile 45 are then spaced apart from each other (whereby the length of the spacer section 23 at least substantially determines the distance) and aligned parallel to each other. The cleaning leg 49 of the additional profile 45 then extends along the normal direction N like the cleaning leg 19 of the base profile 13, and the cover leg 51 of the additional profile 45 extends along the base direction B like the base leg 17 of the base profile 13.

[0076] In Fig. 4Furthermore, a reinforcing mesh 63 is shown, which is arranged parallel to the plaster leg 49 of the additional profile 45 on the plaster leg 49 and projects beyond it parallel to the extension of the plaster leg 49 along the normal direction N. The reinforcing mesh 63 can generally only be arranged on the plaster leg 49 of the additional profile 45 after the basic profile 13 has been coupled to the additional profile 45. Preferably, however, it is already firmly connected to the plaster leg 49 of the additional profile 45 from the outset and is thus part of the additional profile 45.

[0077] The Fig. 5 Figure 1 shows a second embodiment of a plaster sealing strip 11 according to the invention, which differs from the first embodiment primarily in the structure of the base profile 13 and its attachment to the respective component 65; the additional profile 45 of the second embodiment, on the other hand, is at least substantially identical to the additional profile 45 of the first embodiment.

[0078] In the second embodiment, the base leg 17 with a support section 67 extends beyond the building-adjacent end 25 of the spacer section 23, at which the plaster leg 19 projects from the base leg 17. The support section 67 projects from the fastening surface 29 opposite to the normal direction N and then transitions into a contact section 69, which in turn is aligned parallel to the base direction B. An adhesive tape 71 is provided on the contact section 69, by means of which the base profile 13 can be bonded to the building element 65.

[0079] Due to the angled orientation of the support section 67 relative to the mounting surface 29, a gap 73 inevitably remains between the mounting surface 29 and the component 65. A pre-compressed joint sealing tape 75 can be inserted into this gap 73, which expands within it and thus largely fills it. Should the adhesive tape 71 detach from the base profile 13 or the component 65 due to movement of the base profile 13 relative to the component 65, particularly due to thermal factors, the joint sealing tape 75 can continue to expand and fill the gap between the mounting surface 29 and the component 65, thus reliably sealing the joint.

[0080] In the Figs. 6 to 9Different states of the plaster sealing strip 11 are shown, illustrating the process by which a plaster sealing strip 11 according to the invention can be used for the connection of a building element to a building wall. This process is described in the Figs. 6 to 9 shown as an example for the first embodiment; however, it also applies, where applicable, to other embodiments.

[0081] In the Fig. 6In the depicted state of the plaster sealing strip 11, the base profile 13 is attached to the building element 65 by being bonded to the building element 65 (via the first adhesive tape 33 and the intermediate profile 31) with the second adhesive tape 35. The base profile 13 was positioned such that its plaster leg 19 is located parallel to the building wall (not shown) at a short distance (e.g., a few centimeters) from the wall between which the building element 65 is to be connected. The plaster leg 19 was then embedded in a base coat 77 on the building wall. Thus, a base coat 77 was applied to the building wall, surrounding the plaster leg 19 of the base profile 13, so that the plaster leg 19 (close to the building wall) is embedded in the base coat 77.The application of the base coat 77 can be made easier in particular by the fact that the plaster leg 19 has a large number of passages through which the plaster can penetrate it.

[0082] The base coat 77 extends perpendicular to the building wall from the building wall to the boundary section 21 of the base profile 13, which serves as a marker and, if necessary, also as a screeding aid for applying the base coat 77 to the building wall. The tear-off tab 41 prevents plaster from coming into contact with the building element 65 or into the area between the base leg 17 of the base profile 13 and the building element 65 during the application of the base coat 77. To protect the building element 65 over a larger area, a protective film can be additionally glued onto the tear-off tab 41. In particular, the tear-off tab 41 also protects the coupling receptacle 39 formed on the base profile 13 from contamination by plaster.

[0083] When the base coat 77 is completed, the tear-off tab 41 can be detached from the profile body 15 of the base profile 13 at the predetermined breaking point 43 (see arrow in Fig. 6 ). This means that in the Fig. 7 In the shown state of the plaster sealing strip 11, the coupling receptacle 39 is accessible, so that the coupling extension 61 of the additional profile 45 can be inserted into the coupling receptacle 39 and thus the additional profile 45 can be coupled to the basic profile 13 (see arrow in Fig. 7 ). The plaster leg 49 of the additional profile 45 is aligned parallel to the plaster leg 19 of the basic profile 13 in the coupled state of the plaster sealing strip 11 and is arranged at a small distance (for example, less than 1 cm) from the surface of the base plaster layer 77.

[0084] Advantageously, a reinforcing mesh 63 is attached to the plaster leg 49 of the additional profile 45, extending beyond the plaster leg 49 and thus at least substantially along the surface of the base plaster layer 77. If the entire surface of the base plaster layer 77 is not covered by the reinforcing mesh 63 provided on the additional profile 45, a separate reinforcing mesh can also be arranged on the surface of the base plaster layer 77.

[0085] In the Fig. 8In the shown state of the plaster sealing strip 11, the plaster leg 49 of the additional profile 45 is embedded in an additional plaster layer 79 on the base plaster layer 77. Thus, an additional plaster layer 79 was applied to the base plaster layer 77, surrounding the plaster leg 49 of the additional profile 45, so that the plaster leg 49, including the reinforcing mesh 63 attached to it and, if applicable, one or more additional reinforcing meshes, is embedded in the additional plaster layer 79. In the example shown, a topcoat 81 was also applied as part of or on top of the additional plaster layer 79. Overall, the applied plaster extends in a direction perpendicular to the building wall to the free end of the cover leg 51 of the additional profile 45.

[0086] Similar to the process of embedding the plaster leg 19 of the base profile 13, the tear-off tab 53 of the additional profile 45 also prevents plaster from reaching the building element 65 or the area between the cover leg 51 of the additional profile 45 and the building element 65 when applying the additional plaster layer 79 (possibly including the topcoat layer 81). To further protect the building element 65 over a larger area, a protective film can be additionally glued onto the tear-off tab 53. After the embedding is complete, the tear-off tab 53 can then be separated from the profile body 47 of the additional profile 45 along the predetermined breaking point 55 (see arrow in the figure). Fig. 8 The installation of the plaster sealing strip 11, including the plastering in, is then complete. This state is in Fig. 9 shown.

[0087] The two-part design of the plaster sealing strip 11, as well as the way the base profile 13 and the additional profile 45 are coupled with their two plaster legs 19, 49 arranged parallel and spaced apart, facilitates the application of a comparatively thick base coat 77, in particular of an (ultra-)lightweight plaster, as well as the application of an additional plaster layer 79 that stabilizes the base coat 77 and is preferably provided with a reinforcing mesh 63. The plaster sealing strip 11 can simultaneously provide movement compensation and a reliable seal for the joint between the plaster layers 77, 79, 81 and the building wall 63. Reference sign
