Definitions

  • 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.
  • Plaster sealing strips are generally 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 at 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.
  • the plaster sealing strip can be inserted at least partially into this 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 be formed by monolithic masonry.
  • the building wall can also be designed as a thermal insulation composite system. be designed so that the plaster sealing strip is attached to the thermal insulation of the building wall and plastered in. To secure the plaster sealing strip, it is advisable to provide structures on the plaster sealing strip that enable stable plastering.
  • the building wall is made of monolithic masonry
  • it can be expedient to often use (ultra-)lightweight renders for plastering which are applied relatively thickly and additionally provided with a full-surface mesh filler before a finishing render can be applied.
  • These layers can collectively be regarded as an additional render layer, with a reinforcing mesh advantageously being embedded in the additional render layer, particularly in the lowest of the additional render layers mentioned.
  • Conventional plaster sealing strips are not specifically designed for such thick-layer render systems. In particular, conventional plaster sealing strips do not offer any support for applying one or more further render layers to a comparatively thick base render layer.
  • 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 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, in particular manufactured separately from one another.
  • the plaster sealing strip is therefore designed in at least two parts.
  • the plaster sealing strip can consist of the base profile and the additional profile, thus not comprising any further separate components.
  • 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 structural 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.
  • Both the base direction and the normal direction are preferably orthogonal to the aforementioned first longitudinal direction.
  • the base leg and the plaster leg can, in particular, have an at least substantially constant thickness along their respective course, relative to the cross-section of the profile body of the base profile.
  • This thickness can, for example, be 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 base leg and the plaster leg can each be formed by one or more flat sections of the profile body, each of which has a straight course relative to the cross-section of the profile body.
  • the plaster leg can be formed entirely by a single flat section, so that its cross-section has an at least substantially continuous straight course. Since the plaster leg in the normal direction from the base leg, it can extend entirely along this normal direction.
  • the base leg serves for attachment to the building element and/or the building wall in that the base profile is designed to be attached to the building element and/or the building wall via the base leg.
  • the base leg is connected at least to the building element, whereby this connection can in particular comprise gluing.
  • the base leg can also be connected to both the building element and the building wall simultaneously.
  • the connection can be force-locked - exclusively or in addition to another type of connection, such as gluing - namely by clamping at least part of the base leg between the building element and the building wall.
  • the plastering leg of the base profile is intended for plastering onto the building wall in that the base profile is designed so that it is arranged with its plastering leg on the building wall (in particular with the plastering leg parallel to the building wall) and the plastering leg is then plastered into the aforementioned base plaster layer on the building wall so that the plastering leg is embedded in the base plaster layer.
  • the plastering leg also contributes to the attachment of the plaster sealing strip to the building wall.
  • the plastering leg is usually plastered in later than the attachment of the base leg to the building element and/or the building wall.
  • the plastering leg preferably has a plurality of passages through which the plaster can penetrate the plastering leg during plastering.
  • the adhesion of the plaster to the plaster leg can be improved by the plaster leg having, at least on one side, preferably on both sides, a surface profile that improves the adhesion of the plaster, for example in the form of ribs, notches and/or knobs.
  • the fact that the base leg is aligned along the base direction can mean, in particular, that the base leg has its greatest extent in the base direction transverse to the first longitudinal direction and/or that it runs largely or predominantly at least substantially parallel to the base direction.
  • the base leg can extend, for example, over a length of at least 10 cm, in particular at least 12 cm, preferably at least 15 cm.
  • the base profile can, in particular, be designed to be plastered onto 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.
  • the cleaning leg is angled relative to the base leg, as it protrudes from the base leg in the aforementioned normal direction, which is at least substantially perpendicular to the insertion 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 be longer than the base leg.
  • the profile body of the base profile is preferably formed as a single piece.
  • the base leg and the plaster leg of this profile body are not formed separately from one another, but rather form different sections of the profile body based solely on their respective structure, in particular their respective spatial configuration, and their respective function.
  • the profile body can be manufactured as a whole by extrusion. If the profile body is formed from several different materials, it can in particular be manufactured by coextrusion.
  • the base leg and the plaster leg of the profile body preferably comprise the same material and merge directly into one another.
  • the additional profile has a profile body extending in a second longitudinal direction, which comprises a plaster leg for plastering in an additional plaster layer on the base plaster layer.
  • first longitudinal direction and second longitudinal direction serves merely to distinguish them conceptually and is intended neither to imply an order or hierarchy nor to imply that the first longitudinal direction and the second longitudinal direction must necessarily be different from one another. However, they do not have to be similar to one another either.
  • the base profile and the additional profile are not coupled to one another, the spatial orientation of the first longitudinal direction and the second longitudinal direction relative to one another is indeterminate.
  • the cleaning leg of the additional profile can be aligned along a direction orthogonal to the second longitudinal 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.

  • the additional plaster layer can be designed as a finishing plaster layer, to which no further plaster layers are applied. However, it can also be provided that an additional finishing plaster is applied to the additional plaster layer.
  • the plaster leg of the additional profile preferably has a plurality of passages through which the plaster can penetrate the plaster leg during plastering.
  • the adhesion of the plaster to the plaster leg can be improved by the plaster leg having a surface profile on at least one side, preferably on both sides, which improves the plaster's grip, for example in the form of ribs, notches and/or knobs.

  • the plastering leg of the base profile and the plastering leg of the additional profile can be designed identically, for example, with regard to their external shape, dimensions, material, surface structure, and/or the arrangement of passages through the respective plastering leg.
  • the profile body of the additional profile is preferably formed in one piece, so that in particular the plaster leg is not formed separately from the remaining profile body, but merely forms a section of the profile body that is different from other sections of the profile body due to its structure, in particular due to its spatial course, as well as its function.

  • the basic profile has both a coupling extension and a coupling receptacle and/or the additional profile has both a coupling extension and a coupling receptacle.
  • all of these cases are not limited to just one coupling extension or just one coupling receptacle. Rather, the basic profile and the Additional profiles may also have several coupling extensions and/or several coupling receptacles.
  • the number of coupling extensions and the number of coupling receptacles are the same, so that a corresponding number of pairings can be formed, each consisting of one coupling extension and one coupling receptacle (including the pairing consisting of the aforementioned one coupling extension and the aforementioned one coupling receptacle), wherein the coupling extension and the coupling receptacle of a respective pairing are provided on different profiles.
  • the coupling extension is provided on the basic 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 basic profile.
  • 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.

  • the coupling extension When inserted into the coupling receptacle, the coupling extension can snap into the coupling receptacle, as explained in more detail below.
  • the coupling extension and the coupling receptacle can be designed in such a way that the coupling extension, once inserted into the coupling receptacle, can no longer be removed from the coupling receptacle (at least not without damaging at least part of the plaster sealing strip), so that the coupling of the base profile and the additional profile is irreversible.
  • the coupling extension can be removed from the coupling receptacle again after insertion into the coupling receptacle, if necessary by applying a certain force to overcome any locking effect.
  • the coupling extension and the coupling receptacle each preferably extend along the first longitudinal direction or the second longitudinal direction (depending on which profile they are provided), in particular over the entire length of the respective profile.
  • the coupling extension can, for example, be designed as an elongated web section, wherein the web section is preferably continuous in the respective longitudinal direction, but can in principle also have interruptions.

  • 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 one another, with this alignment advantageously resulting automatically from the coupling by inserting the coupling extension into the coupling receptacle. It is therefore not necessary to precisely align the additional profile on the building wall.
  • the coupling extension is preferably inserted into the coupling receptacle in a direction perpendicular to the longitudinal directions, which is in particular aligned 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.

  • the coupling allows the plaster leg of the additional profile to be at least substantially flush with the base coat of plaster. If, however, the additional profile were connected to the base profile from the outset, it would hinder the application of the base coat of plaster (particularly if it is covered with a reinforcing mesh). Due to this coupling, the additional profile, unlike the base profile, does not need to be carefully aligned to the building wall, as precise alignment of the additional profile results directly from the coupling to the already aligned base profile.
  • an additional plaster layer can be applied to the base plaster layer, into which the plaster leg of the additional profile is embedded.

Depending on the spacing of the plaster legs when coupled, the base plaster layer can be comparatively thick.

Whether they are actually “near the building” or “far from the building” depends, of course, on whether the plaster sealing strip is positioned on the building wall. However, the plaster sealing strip is designed to be positioned on the building wall, particularly with the base direction perpendicular to the building wall, in such a way that the end of the distance section closest to the building is closer to the building wall than the end of the distance section far from the building.

  • This free space can be formed in particular by the base profile having at least one support section which projects from the fastening surface in the opposite direction to the normal direction, so that the fastening surface cannot be brought closer than a certain distance defined by the length of the support section. A defined minimum distance can be approximated to the component, thus inevitably leaving the aforementioned free space between the fastening surface and the component.
  • This free space is then limited laterally, particularly opposite to the base direction, by the support section.
  • the coupling extension or the coupling receptacle preferably directly borders the free space.
  • the free space can, in particular, serve to accommodate a joint sealing tape of the type mentioned.
  • the joint sealing tape can be inserted into the free space in a compressed state, particularly after the base profile has been arranged on the building wall and, if necessary, fastened to the building element via a fastener.
  • the base profile is preferably already plastered into the base plaster layer with its plaster leg; however, this is not absolutely necessary.
  • the joint sealing tape can expand to seal the gap between the fastening surface and the building element.
  • the joint sealing tape can also be arranged on the fastening surface from the outset, in particular before the base profile has been arranged on the building element and, if necessary, fastened.
  • the base profile can initially be held in a pre-compressed state (e.g., by an enveloping film) and only released for expansion after the base profile has been fastened to the building wall and/or the building element (e.g., by cutting through or dissolving the film).
  • a pre-compressed state e.g., by an enveloping film
  • only released for expansion after the base profile has been fastened to the building wall and/or the building element (e.g., by cutting through or dissolving the film).
  • locking means are provided on the coupling receptacle and on the coupling extension, wherein the locking means of the coupling receptacle (ie the locking means provided on the coupling receptacle) and the locking means of the coupling extension (ie the locking means provided on the coupling extension) when inserting the coupling extension into the coupling receptacle are mutually aligned with respect to the direction of insertion engage behind, so that the base profile and the additional profile are positively secured against loosening from one another by the engagement behind.
  • the coupling extension can have at least a substantially circular cross-section at its tip, and the coupling receptacle can have a C-shape in cross-section, the inner diameter of which corresponds at least substantially to the outer diameter of said circular shape.
  • the ends of the C-shape must therefore be temporarily widened and then (when the circular shape is fully incorporated into the C-shape) engage behind the C-shape with respect to the direction of insertion, so that the coupling extension is positively secured in the coupling receptacle.
  • the locking means can, for example, comprise at least one locking projection (on the coupling extension or the coupling receptacle) and at least one locking recess (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 fully inserted into the coupling receptacle, engages in the locking recess in a resilient manner.
  • This engagement occurs in particular in a direction transverse to the direction of insertion and, in this respect, corresponds to the aforementioned engagement behind the coupling extension with respect to the direction of insertion, which then positively secures the coupling extension against leaving the coupling receptacle opposite to the direction of insertion.
  • the locking projection can be designed in particular as a locking tongue or in the manner of a barb or a pawl.
  • the locking recess can be designed essentially complementary to the locking projection.
  • several locking recesses are provided, which are designed in the manner of a toothing, wherein the locking projection engages successively in each of these partial recesses upon insertion of the coupling extension into the coupling receptacle. In this way, the coupling extension can be secured at several different insertion depths in the coupling receptacle, similar to a cable tie.
  • the figures show various embodiments of 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 L 1 , L 2 running perpendicular to the plane of the image and have the cross section shown at least essentially over their entire longitudinal extent. Elements of different embodiments that correspond to one another are identified by the same reference numeral.
  • Fig. 1 shows a base 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 an at least 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 far from the building, wherein the spacer section 23 corresponds to the entire base leg 17 in the first embodiment.
  • the plaster leg 19 protrudes from the base leg 17 in a normal direction N oriented perpendicular to the base direction B and to the first longitudinal extension L 1 , while the boundary section 21 at the end 27 remote from the building also protrudes from the base leg 17 in the normal direction N.
  • 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).
  • the base profile 13 is a flat, 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 fastening surface 29 via a first adhesive tape 33; a second adhesive tape 35 is adhered to a second side surface of the intermediate profile 31 opposite the first side surface, via which the intermediate profile 31 can be adhered to the respective component.
  • the first adhesive tape 33 and the second adhesive tape 35 are each foam adhesive tapes. While the second adhesive tape 35 extends essentially 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. As a result, there is a free space 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 of the spacer section 23 of the base leg 17 remote from the building.
  • a membrane 37 Spanning this free space is a membrane 37, which is connected on the one hand to the fastening surface 29 and on the other hand to the intermediate profile 31, and whose cross-sectional length is greater than the thickness (extension along the normal direction N) of the first adhesive tape 33.
  • the first adhesive tape 33 Due to the smaller extension along the base direction B and/or due to the formation of the respective adhesive connection, the first adhesive tape 33 has a lower adhesive force than the second adhesive tape 35. If the profile body 15 of the base profile 13 should move away from the respective component, for example for thermal reasons, the connection between the fastening surface 29 and the intermediate profile 31 is released, while the connection between the intermediate profile 31 and the component remains intact. However, the fastening surface 29 and the intermediate profile 31 then advantageously remain are still connected to each other via the membrane 37, so that the joint between the base profile 13 and the structural element remains sealed. In this way, the plaster sealing strip 11 allows for movement compensation while still providing reliable sealing.
  • a coupling receptacle 39 of the base profile 13 is formed at the end 27 of the spacer section 23 of the base leg 17 remote from the building.
  • This coupling receptacle 39 is essentially designed as a groove that extends along the first longitudinal direction L 1 and, in the first embodiment, has a C-shaped cross-section.
  • the coupling receptacle 39 is formed on the side of the fastening surface 29 and is open in the base direction B (pointing away from the end 25 near the building).
  • the base profile 13 further comprises a tear-off tab 41, which is connected to the end 27 of the spacer section 23 of the base leg 17 remote from the building via a predetermined breaking point 43 and is aligned parallel to the base direction B, so that it is arranged in direct extension of the base leg 17. Along the predetermined breaking point 43, the tear-off tab 41 can be separated from the profile body 15 of the base profile 13.
  • the coupling receptacle 39 serves to couple the base profile 13 with a Fig. 2 separately shown additional profile 45.
  • This additional profile 45 comprises a profile body 47 which extends in the second longitudinal direction L 2 , which in the coupled state of the plaster sealing strip 11 (ie when the base profile 13 and the additional profile 45 are coupled together; see e.g. Fig. 4 ) coincides with the first longitudinal direction L 1 .
  • the profile body 47 of the additional profile 45 comprises a plaster leg 49, which is basically similar to the plaster leg 19 of the basic profile 13 and extends with at least a substantially straight course along a second Longitudinal direction L 2 extends vertically. In the coupled state of the plaster sealing strip 11, this direction corresponds to the aforementioned normal direction N.
  • the profile body 47 of the additional profile 45 comprises a cover leg 51, which in the first embodiment protrudes perpendicularly from one end of the plaster leg 49.
  • the cover leg 51 protrudes 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.
  • 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, namely to an end of the cover leg 51 spaced 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.
  • the covering leg 51 protrudes from a front side 57 of the plaster leg 49 of the additional profile 45.
  • a coupling extension 61 is formed, which is at least substantially perpendicular to the plaster leg 49.
  • the coupling extension 61 is designed as a web protruding from the rear side 59, the free end of which has a circular, thickened cross-section. As a result, this free end of the coupling extension 61 is at least substantially complementary to the C-shape of the coupling receptacle 39.
  • the diameter of the circular shape is slightly larger than the opening of the C-shape, so that the opening is temporarily widened when the coupling extension 61 is inserted into the coupling receptacle 39 and, after insertion, engages behind the circular shape. In this way, the coupling extension 61 snaps into the coupling receptacle. 39 and is thus positively secured against leaving the coupling receptacle 39.
  • the toothing is in each case so asymmetrical that when an attempt is made to pull the coupling extension 61 out of the coupling receptacle 39 in the opposite direction to the direction in which it was inserted into the coupling receptacle 39, the tooth flanks of the internal toothing of the coupling receptacle 39, which are oriented perpendicular to this direction, and the tooth flanks of the external toothing of the coupling extension 61, which are also oriented perpendicular to this direction, are pressed flat against each other and thereby block removal of the coupling extension 61 from the coupling receptacle 39.
  • an irreversible coupling can be achieved by this type of design of the coupling receptacle 39 and the coupling extension 61, whereas the coupling of the first embodiment can also be released again.
  • Fig. 4 are these in Fig. 1 shown basic profile 13 and the one in Fig. 2 shown additional profile 45 of the first embodiment of a plaster sealing strip 11 according to the invention in the coupled state. If the base profile 13 has the tear-off tab 41 as in the first embodiment, this must be used to couple the base profile 13 with the additional profile 45 by inserting the coupling extension 61 into the coupling receptacle 39 must first be separated from the profile body 15 at the predetermined breaking point 43. The tear-off tab 41 is then no longer part of the base profile 13 and therefore in Fig. 4 also not shown.
  • the first longitudinal direction L 1 and the second longitudinal direction L 2 coincide; moreover, the cleaning leg 19 of the base profile 13 and the cleaning leg 49 of the additional profile 45 are then arranged at a distance from one another (with the length of the spacer section 23 at least substantially specifying the distance) and aligned parallel to one another.
  • the cleaning leg 49 of the additional profile 45 then extends, like the cleaning leg 19 of the base profile 13, along the normal direction N, and the cover leg 51 of the additional profile 45 extends, like the base leg 17 of the base profile 13, along the base direction B.
  • a reinforcing mesh 63 can be seen, which is arranged parallel to the plastering leg 49 of the additional profile 45 and projects beyond the plastering leg 49 parallel to the extension of the plastering leg 49 along the normal direction N.
  • the reinforcing mesh 63 can generally only be arranged on the plastering leg 49 of the additional profile 45 after the coupling of the base profile 13 to the additional profile 45. Preferably, however, it is already firmly connected to the plastering leg 49 of the additional profile 45 from the outset and is thus part of the additional profile 45.
  • the Fig. 5 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 structural element 65; the additional profile 45 of the second embodiment, however, is at least substantially identical to the additional profile 45 of the first embodiment.
  • the base leg 17 extends with a support section 67 beyond the building-proximate end 25 of the spacer section 23, at which the plaster leg 19 protrudes from the base leg 17.
  • the support section 67 protrudes from the fastening surface 29 opposite the normal direction N and then merges 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, via which the base profile 13 can be adhered to the building element 65.
  • a free space 73 inevitably remains between the fastening surface 29 and the structural element 65.
  • a pre-compressed joint sealing tape 75 can be inserted into this free space 73, which can expand in the free space 73 and thus largely fill it. Should the adhesive tape 71 become detached from the base profile 13 or the structural element 65 due to a movement, in particular due to thermal factors, of the base profile 13 relative to the structural element 65, the joint sealing tape 75 can continue to fill the space between the fastening surface 29 and the structural element 65 by further expanding and thus reliably seal it.
  • Fig. 6 to 9 Different states of the plaster sealing strip 11 are shown, which illustrate the process according to which a plaster sealing strip 11 according to the invention can be used for the structural connection of a building element to a building wall. This process is shown in the Fig. 6 to 9 shown as an example for the first embodiment; however, it also applies, where applicable, to other embodiments.

  • the plaster leg 19 was then plastered into a base plaster layer 77 on the building wall.
  • a base plaster layer 77 was therefore applied to the building wall, surrounding the plaster leg 19 of the base profile 13, so that the plaster leg 19 is embedded (near the building wall) in the base plaster layer 77.
  • the application of the base plaster layer 77 can be made easier in particular by the fact that the plaster leg 19 has a plurality of passages through which the plaster can penetrate.
  • the base plaster layer 77 extends in a direction 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 removal aid for applying the base plaster layer 77 to the building wall.
  • the tear-off tab 41 prevents plaster from getting onto the building element 65 or into the area between the base leg 17 of the base profile 13 and the building element 65 when the base plaster layer 77 is applied.
