Description

The invention relates to a connection profile strip, in particular a soffit connection profile strip, having a profile body with an outer leg and a component fixing section movably connected thereto via two connecting webs for fastening the strip to a frame or rail component, in particular a door or window frame or a roller blind rail, via an adhesive surface ,

Such moldings are usually used to produce a transition between a window or door frame or a roller blind rail and an adjoining wall, with known connection profiles either connect to a plaster layer, or serve the inclusion of cladding panels or the like. In known strips a relative mobility of the component mounting portion, ie the profile body part, which is attached via the adhesive surface on the frame or the rail to the outer leg, are provided on the example projecting webs or the like, realized via connecting webs connecting the outer leg and the component mounting portion , and which consist of a softer material than the outer leg and the component mounting portion, such as soft PVC, while the other profile body parts made of hard PVC. This relative mobility makes it possible, to a certain extent, to be able to compensate for any movements that occur over time between the frame or rail component and the plaster surface in which the outer leg is anchored and at the same time maintain the connection and sealing realized via the strip hold. Nevertheless, the connecting webs are still relatively rigid in known strips, the maximum mobility of the component mounting portion relative to the outer leg, in particular in the transverse direction, is therefore low.

DE 20 2005 020 164 U shows a connection profile strip according to the preamble of claim 1.

The invention is thus based on the problem of specifying a connection profile strip in which a sufficiently large relative displacement of the attachment section to the outer leg, in particular seen in the horizontal direction of movement, is given.

The solution to this problem is provided by the characterizing features of claim 1.

The eformungsgemäße connection profile strip is characterized by highly flexible connecting webs, which thus consist of a very soft, elastic material very easily deformable, so that consequently oppose the connecting webs of an acting movement or displacement force a barely noticeable resistance. The plastic or rubber material used should therefore have the lowest possible Shore hardness, for example, a hardness Shore ≤ A50, preferably ≤ A30. This high flexibility allows the profile strip can very easily and completely adapt to any building movement and in particular the connection region of the component mounting portion to the frame or rail component in a shift if at all minimal forces act, since the connecting webs due to their very easy deformability no Apply stresses or forces on the frame attachment portion and over this the adhesive bond to the frame or rail component.

Furthermore, the Anschlussprofilleite characterized by the fact that the highly flexible connecting webs are formed curved, so that they allow a simple horizontal displacement and carry out a rolling or rolling-like movement in this. That is, the connecting webs are designed to be curved outward from the house. Now acts a force on the connecting webs in a horizontal or transverse direction, they respond immediately because of their high flexibility and roll or roll, following the force, to the side from. About this rolling or Abwälzeigenschaft a considerable movement distance, along which therefore the relative displacement of the frame mounting portion to the outer leg is possible, can be realized. traveling distances from 3 - 4 mm to each side, starting from the center position, are readily feasible. The connection profile strip according to the invention thus allows for motion compensation of the connected structural parts, wherein it reacts even with minimal movements or acting forces in the connecting bridge area and is able to completely accommodate even large construction-side movement distances, without the risk that the connection, for example in the area the bonding of the component mounting portion ruptures.

In order to realize the largest possible rolling or rolling distance, the connecting webs open at the smallest possible, acute angle on the outer leg or the mounting portion, preferably they are the outer leg and the mounting portion at an angle ≤ 45 °, in particular ≤ 30 °. The curved webs thus open as flat as possible, resulting in a relatively large, free curved web length, resulting in a large displacement or Abrolllänge. The distance of the outer leg to the attachment portion, based on the inner sides, is at least 2 mm. In conjunction with the very shallow angle of the webs relative to the outer leg and the attachment portion resulting from this necessarily large free leg lengths. The thickness of the connecting webs should be ≦ 2 mm, in particular ≦ 1 mm, and preferably in the range between 0.5 to 0.7 mm. The thinner the connecting webs, the greater the flexibility of this deformation section, wherein the thickness of the connecting webs of course, taking into account the distance of the outer leg of the mounting portion as well as the distance of the connecting webs from each other, therefore ultimately the size of the profile body can be selected. However, a web width ≤ 1 mm, especially in the specified range between 0.5 - 0.7 mm in the usual connection profile list sizes has been found to be particularly useful. It should be noted here that, of course, all other values above 0.7 mm and below 0.5 mm apply as essential to the invention.

The connecting webs, which consist of a soft, elastic plastic or rubber material, are expediently with the other Components of the profile body, insofar as they are extruded from plastic, produced together in a coextrusion process, thus formed so. This applies with respect to each embodiment of the invention the Anschlussprofilleite. In this case, the connecting webs are part of an integral, arranged on the outer web loop, which forms the or at least a part of the fastening portion. In this embodiment of the bar, for example, made of hard PVC outer web, for example, made of very soft plasticized PVC integrally formed loop formed quasi a hollow chamber and forms the two connecting webs. Further, it also forms either the attachment portion itself, then directly on the adhesive layer is applied or, for example, a foam tape with the underside adhesive layer, or it forms part of the mounting portion on which part then another strip or the like is formed of a harder material, the then wear the adhesive layer or the foam tape, etc. This will be discussed below. In this embodiment of the invention, therefore, a complete loop is formed on the outer web, which is multifunctional and just forms the connecting webs as well as the attachment portion itself or at least a part thereof. In this case, the thickness of the loop portion which forms the part or part of the fastening portion may be equal to or greater than the thickness of the connecting web. For stability or strength reasons, it is sufficient if the loop has a uniform thickness everywhere. Sometimes, however, it may be expedient, for example if an adhesive layer or a foam adhesive tape carrying it is glued directly to the part of the loop section forming the fastening section, to make this loop section somewhat stronger, ie more stable.

As an alternative or in addition to this, as already described, a stiffening part forming a further part of the fastening section can also be arranged on the loop in the form of a stiffening strip, ie likewise preferably coextruded. This is conceivable, for example, if the loop as a whole has the same thickness overall, and therefore is also very thin in the central loop section, which forms part of the fastening section. about this stiffening strip, for example, again made of rigid PVC, then, if desired, an even greater strength or rigidity in the attachment portion area can be realized.

It is also conceivable to arrange on the outer leg, only the two connecting webs, and these to form the attachment portion at the other end to a side rail, which in turn is preferably formed in accordance with the rest of the profile body of a harder material such as rigid PVC to bind. In this embodiment, in turn, a hollow chamber is formed, but in conjunction with the additional leg strip.

Basically, there are two possibilities with regard to the connection of the connecting webs on the outer leg. On the one hand, these can be arranged at a distance from one another on the outer limb, that is to say they can therefore be integrally formed on two separate attachment points on the outer limb. Alternatively, when forming a loop, but also possible to let the connecting webs pass into a connecting portion, which is then integrally formed on the outer leg. If a loop is formed, it is possible to fix them in two separate points on the outer leg, or over the entire surface via a connecting portion, that is, the loop itself is virtually a molded hose.

As already described, the adhesive layer can be applied directly to the fastening section, in particular the loop or the loop section or the connecting strip. Alternatively, it is also conceivable to arrange a foam tape exhibiting the foam tape. This foam tape is a tape adhesive on both sides, over which an adhesive layer is the fixation of the tape to the attachment portion, be it the loop or the loop portion or the stiffening strip, on the other adhesive layer, the profile strip is fixed to the frame member. Of course, this adhesive layer is coated with a peelable protective tape, usually a silicone Tape, covered. It is also conceivable, however, to apply an adhesive layer without foam backing directly on the attachment section and to cover it with a masking tape.

In the case of known connection profile strips, a web adjoining the plaster layer and projecting vertically from the outer leg is frequently provided on the outer leg, which web is visible in the assembly position and forms a clean connection to the plaster layer. In the assembly position, the area located below the outer leg, including the connecting sections and the fastening section, is therefore optionally free, together with the foam adhesive tape located there. That is, from the outside, at least the outer connecting web and the frame mounting portion and optionally the foam adhesive tape is visible. Occasionally, a side-projecting sealing lip is formed on the attachment portion, which covers the foam adhesive tape, so that in this case this sealing lip would be visible. Overall, therefore, from the bar various parts visible below the outer leg in the mounting position, which is not always advantageous or desirable from an optical point of view. In order to counteract this, an expedient embodiment of the invention provides that the profile body is provided with a covering web which is at least partially, preferably completely, concealing the connecting web which is external in the assembly position. This fairing web, which is preferably arranged close to or at the edge of the outer leg, thus extends to a certain extent laterally of the connecting webs and optionally of the foam adhesive tape, so at least partially covers the area located below the outer web. It remains in the mounting position thus a shadow gap to the frame member, which is more or less wide, depending on how far the fairlead is pulled. The final joint width is ultimately dependent on the specific design of the profile strip, in particular the actual size or the profile body structure. It is for example in the range between about 1 - 10 mm, preferably between 1 - 5 mm, in particular between 1 - 3 mm, with smaller strips a joint width of, for example, 1 - 3 mm can be realized, as assumed by these strips component displacements are not too big, while with large moldings too Joints of, for example, 5 mm and more may remain. This remaining shadow gap, which in principle should be kept as small as possible in the mounting position, is visually appealing, so on the visible side, therefore, ultimately only the fairing web is to be seen as a straight-line visual element, which is visually appealing.

If, according to a first embodiment of the invention, an outer web in the assembly position, which adjoins the plaster layer as described and preferably protrudes vertically from the outer web, may be designed to be extended to form the lining web. The outer bridge serves as a trigger bar, which is followed by the plaster layer. This web is now perferably extended downward, so that the cladding web is formed in the immediate extension. In the assembly position is thus only then visible to the plaster layer of the web and extending it lining web, then followed by the narrowest possible shadow gap. This results in a very attractive, homogeneous appearance.

Alternatively, however, it is also conceivable for a web which is external in the assembly position and which preferably protrudes vertically from the outer limb to be provided on the profiled body, which web is arranged offset horizontally with respect to the cladding web. In this embodiment of the invention, the web is not formed on the outer leg edge, but slightly further inside, so that it is covered in the mounting position of the subsequent plaster layer, that is embedded in this. It is a plaster to be plastered under plaster. The plaster layer runs to the outer leg, then it is immediately followed by the fairing web. In the assembly position, then only the narrow, eg only 1 - 4 mm wide panel web is visible, which then passes directly into the shadow gap of one or a few millimeters wide. From the profile strip so that ultimately only the fairing web is visible, optionally, if still provided, the sealing lip, which possibly expires in the shadow gap, but otherwise the profile bar is completely gone.

In known connection profile strips as described is often provided on the profile body or on the outer leg in the mounting position outer web, which usually protrudes vertically from the outer web, and which serves the plaster deduction. The plaster layer extends to the upper edge of the bridge, this is visible with its outer surface in the mounting position. That is, the profile strip is almost completely visible in the mounting position with its outer side, the viewer can see the web outside, as well as any located below the outer leg profile strip parts such as the outer connecting bar and possibly the foam adhesive tape, etc. To give the opportunity, the building visually To make more appealing, provides an expedient development of the invention that the profile body in the mounting position outer web on its outside with a liability of a male plaster or paint layer improving surface or serving for this purpose three-dimensional O-berflächestruktur, z. B. is provided a roughening. According to this embodiment of the invention, the bridge serves as a plaster or color carrier, that is, it is completely plastered or painted on the outside, so that it is not visible in the mounting position. It is therefore a Einputzsteg. In order to allow optimal adhesion of the plaster or a layer of paint, the outside of the Einputzsteges is provided with a corresponding adhesion-improving coating or structured in three dimensions. Over this covering or the surface structure a secure anchoring of the applied plaster or paint layer is ensured on the Einputzstegaußenfläche, so that it is avoided that in the course of time to a detachment of the plaster or paint layer. In the assembly position is thus visible from the profile strip if at all only the subsequent below the outer web strip part. However, this can also be hidden visually appealing, if, as further provided according to the invention, the cladding web is provided with such a liability of the applied plaster or paint layer improving coating or such a surface structure. In particular, if the Einputzsteg is extended and merges directly into the panel web, it is readily possible to apply the adhesion-improving coating on the entire profile body outside, formed by the outside of the Einputzsteges and the fairing web, or to provide said side with the structuring. The profile bar is then complete disappeared under plaster or paint, it is only the shadow gap to see. At the same time, however, the excellent properties of the strip according to the invention with regard to the absorption of longitudinal and transverse forces due to the working structure are retained.

With regard to the usable surface different possibilities are given. According to a first alternative of the invention, the pad may be a preferably glued structured band, z. As a plastic or textile fabric tape, or a glued fabric, for. As a fiberglass fabric, or applied by the type of flocking fibers, in each case in particular of plastic or textile, be. Over the tape or fabric or fibers, a surface structuring is achieved, which makes it possible that in particular the plaster layer can dig into the surface structure. The tape or fabric or flakes may be plastic. For example, a perforated or otherwise three-dimensionally deformed plastic tape, optionally provided on the back with a self-adhesive layer, are glued. The fabric can be, for example, a textile fabric made of synthetic fibers which, for example, is woven very coarsely or consists of thick fibers, so that a corresponding "open-pored" weave structure results. For "flocking" preferably plastic fibers of one or more millimeters in length can be used, which are applied for example to a previously applied adhesive layer, or which are optionally contained in a curing or self-adhesive support material, which is applied to the outside of the Einputzsteges and optionally the panel web , The fibers embedded in the carrier mass protrude from this, thus forming a three-dimensionally structured surface when the carrier material, for example a curing adhesive or synthetic resin, has hardened. There are no restrictions with regard to the strip or fabric used or the fibers used, as long as the adhesion-improving structuring of the web surface can be achieved.

As an alternative to the coatings described, the coating may also be an adhesive or cured carrier medium with particles applied thereto or incorporated therein, in particular quartz powder or sand. The structuring takes place here via applied or introduced particles, primarily quartz powder or sand is used, especially quartz powder or sand are alkaline resistant, which is advantageous in terms of applying plaster layers. The particles, regardless of which particles are introduced or applied, should have a size of at least 0.5 mm, preferably 1 mm or more, to impart sufficient surface roughness. In this case, the application of the particles can take place in such a way that first an adhesive layer or a carrier medium is applied to the web outside, onto which the particles are then scattered. However, it is also conceivable to use a correspondingly applicable viscous mass, consisting of the carrier medium and particles mixed therein, preferably sand, which mass is applied to the web outside and then cured.

Finally, the coating may also be a bonding agent, ie a coating which per se does not have a three-dimensional structure, but on account of its chemical or physical properties offers a particularly adhesive substrate for the plaster or color coat to be applied thereto. This adhesive layer coating is applied to the outside in the liquid state and then cured.

Fig. 1 shows a connection profile strip 1 according to the invention with a profile body 2 comprising an outer leg 3 and a Bauteilbefestigirngsabschnitt 4, wherein the outer leg 3 and the component mounting portion 4 via flexible connecting webs 5 vertically to each other and are movable transversely to each other, as shown by the crossed double arrows.

On the outer leg 3, two substantially vertically projecting Einputzstege 6, 7 are provided, wherein the outer Einsputzsteg 7 is formed extended into the region below the outer leg 3 and a Verkleidungssteg 8 forms, which extends as far to the side next to the outer connecting web 5 So this covers in the mounting position. In the illustrated embodiment, an integrally formed sealing lip is shown at the lower edge of the trim strip 6, which consists of a softer plastic material than the hard profile body parts in the form of the outer leg 3 and the Einputzschenkel 6, 7 and the fairing web 8. While these example Hard PVC, the sealing lip 9, if it is provided, from very soft, flexible soft PVC with low Shore hardness formed in a coextrusion process. On the lining web 8, substantially at right angles to this projecting, a cover strip 10 via a predetermined breaking point 11, here, for example, in the form of a material weakening, formed, which carries an adhesive member 12, for example in the form of a double-sided adhesive tape (foam adhesive tape) on the top the Abdecklasche 10 is glued. The upper adhesive surface is covered with a protective strip, it can be exposed if necessary. On this Abdecklasche 10, a protective film can be glued, which serves to cover a subsequent window or the like. After use, the cover flap 10 can be separated from the profile body 3 in the region of the predetermined breaking point 11.

Further shows Fig. 1 an applied on the outside of the outer Einputzsteges 7 and the trim strip 8 pad 13, which serves to improve the adhesion of a applied plaster layer, with respect to what Fig. 2 will be discussed in more detail. This covering can be an applied fabric or a structured tape or applied fibers or chips etc. Any material which produces sufficient surface texturing or profiling to ensure that the applied plaster or the like adheres well is suitable. Instead of a covering, it would also be conceivable to provide the outside of the webs 7 and 8 themselves with a three-dimensional surface profiling, for. B. roughen or provided with notches or grooves, etc.

As described, the outer leg 3 and the component mounting portion 4 are connected to each other via the flexible connecting webs 5. The connecting webs 5 themselves are part of a one-piece loop 14 which is fastened on the one hand to the outer leg 3 and forms part of the Bäuteitbefestigungsabschnitts 4 with the lower loop section 15. The component mounting portion 4 is formed here from the loop portion 15, in the example shown, a double-sided adhesive foam adhesive tape 16 with a lower adhesive layer 17, which is covered with a protective tape to be deducted for adhering (silicone tape) is glued. About this adhesive layer 17, the attachment to the frame or rail component, which will be discussed below. On the outer leg 3, the two connecting webs 5 in the areas 18 are firmly connected to the outer leg. The molding of the loop 14 on the outer leg 3 is advantageously also carried out in a co-extrusion process. The material of the loop 14 and thus that of the connecting webs 15 is very soft and flexible to choose, it may, for example, also be soft PVC, with a Shore A hardness as low as possible (eg Shore A ≤ 30) is select, so that the connecting webs 5 are highly flexible and allow a relative movement of the component mounting portion to the outer leg, even at very low acting transverse or longitudinal forces. Other soft plastics can be used, as well as a loop or the connecting webs may be made of rubber or a rubber-like material. For this purpose, the connecting webs are to be made as thin as possible, the wall thickness of the connecting webs 5 should be ≤ 1 mm, it should preferably be in the range between 0.5 - 0.7 mm, but it is also not excluded, even thinner wall thicknesses, for example 0 , 3 or 0.4 mm, depending on the material used and the size of the strip as well as the intended use. The connecting webs 5 are evidently shaped curved outward. They are at a very shallow angle to the underside of the outer leg 3, so run from this as flat as possible and then go over into the bend. In a corresponding manner they run as flat as possible in the mounting portion 4, so that overall results in a relatively large bend or rounding. This geometry, in conjunction with the high flexibility of the connecting webs, realized on the material used and the small web thickness, allows a highly flexible relative movement of the component mounting portion 4 to the outer leg by the connecting webs 5 can be deformed or deformed in the manner of a rolling motion, hereinafter will be received.

Fig. 2 shows the profile strip 1 Fig. 1 in the assembly position. As can be seen, it is attached via the adhesive layer 17 to a component 19, for example to the window frame, which is connected via an adhesive or insulating layer 20 with a masonry 21. The profiled strip 1 is embedded in a plaster layer 22, which surrounds the Einputzstege 6, 7 as well as the U-shaped area between the Einsputzstegen 6, 7 and the outer leg 3 fills. Visible is the plaster layer 22 also applied to the outside of the Einputzsteges 7 and the local coating 13, so that the profiled strip 1 is almost completely hidden. The profile body 2 is therefore not visible. It remains only a very narrow shadow gap 23 between the lower edge of the panel web 8 and the component 19. This shadow gap is for example 1 - 2 mm, that is, the joint allows a vertical movement of the mounting portion 4 relative to the outer leg in a building movement. Of course, the size of the shadow gap ultimately depends on the size of the profile strip. Basically, the shadow gap should be in the range of one or less millimeters.

In any case, the outer side of the profiled strip 1 can be placed completely under plaster over the formation of the covering web 8 in conjunction with the applied adhesive coating 13, so that the profile strip is not visible and. Forms a clean, visually appealing shadow gap 23, which can be kept so narrow that the area behind it is not visible.

The FIGS. 3 and 4 show two views in which the component mounting portion 4 is displaced relative to the outer leg 3. In Fig. 3 is the component mounting portion 4, as shown by the arrow, moved far to the right. This is possible with minimal effort, since the connecting webs 5 are so flexible and can be deformed so easily in the form of their curved geometry that a rolling movement takes place at a force input in the horizontal direction. As can be seen, the mutually overlapping connecting web portions of the two connecting webs 5 in this case move, they slide away one above the other, so that there is an overall rolling or rolling movement, as is known per se in such a loop geometry. The curved configuration allows a considerable movement or displacement path to the side, be it to the right or (see Fig. 4 ) left to. The maximum movement length ultimately depends on the free length of the connecting webs 5, which in turn depends on the distance of the component mounting portion 4 to the outer leg and the bending radius. Movement distances of 2 - 4 mm in each direction are conceivable and feasible, with larger profile strips certainly more. Even a vertical movement in the range of several millimeters is, depending after distance from the component mounting portion to the outer leg 3, given the component mounting portion 4 is also moved slightly vertically to the outer leg 3 in a horizontal movement. Overall, therefore, allows the highly flexible design of the connecting portions 5, resulting from the very soft, flexible plastic material in conjunction with the small thickness and the curved configuration of the invention, the particularly advantageous roll-like deformability of the connecting webs under the action of a transverse force, so that a highly flexible system is created , which can compensate for even small component movements safely, without the movement coupling between the mounting portion and outer leg of such compensation, a resistance is opposed and there is any replacement in the connection area.

The FIGS. 5 to 10 show various embodiments of the invention connecting profiled strips. As far as possible, the same reference numerals are used to designate the same elements. Basically, the structure of each profile strip is essentially the same. In each case, an outer leg 3 made of hard plastic material is provided, with which a fastening section 4 is coupled in a highly flexible manner via the connecting webs 5. In Fig. 5 the connecting webs 5 are connected in the region of attachment to the outer leg 3 via a connecting portion 24, that is, it forms here a total of a tubular loop 14, which is thus completely closed. This results in a very large-scale connection to the outer leg 3 in a single, very wide connection area 18, unlike the embodiment according to Fig. 1 where two separate connection areas 18 are provided. Regardless of the type of connection, the extremely high flexibility and freedom of movement result here as well. On the outer leg 3, a further central anchoring web 25 is here in addition to the two edge Einputzstegen 6, 7 is provided, which is optional. For the sake of clarity, the cover tabs 10 are not shown in this and the following embodiments. These can be provided, but not necessarily. Unlike in the previously described embodiment, here the adhesive layer 17 is exemplarily directly on the loop 14 and the loop portion 15 applied, there is no foam tape disposed therebetween.

At the profile strip 1 off Fig. 6 is also a closed, tubular loop 14 is provided, according to the embodiment according to Fig. 4 , There, however, the component mounting portion 4 is not formed by a foam adhesive tape 16 with adhesive layer 17 underneath, but rather a relatively stiff, preferably also made of harder material (corresponding to the material of the outer leg 3, eg hard PVC) on the loop portion 15 Stiffening strip 26 arranged, which can also be formed in a co-extrusion process. This results in a stiffer attachment portion 4 as compared to the more elastic attachment portion 4 comprising the soft foam adhesive tape 16. In any case, an adhesive layer 17 is also applied to the stiffening strip 26, in this case directly. Furthermore, according to the embodiment Fig. 6 between the two Einputzstege 6, 7 via a holding or clamping portion 27 (piping) added a plaster fabric 28 which is integrated into the plaster layer for even better anchoring.

In embodiment after Fig. 7 the soft plastic loop 14 is again arranged in two separate attachment areas 18 on the outer leg 3. Again, a stiffening strip 26 is placed on the loop portion 15, but here on a foam adhesive tape 16, which carries the adhesive layer 17, is applied. The fairing leg 8 is pulled down a little further, since the entire structure below the outer leg 3 is slightly stronger in order to cover this largely to form the shadow gap.

A further embodiment of a profiled strip 1 according to the invention Fig. 8 , Also there, the material loop 14 is arranged from highly flexible soft plastic material in a single, large-scale attachment portion on the outer leg 3. However, the ends of the connecting webs 5 are arranged here in separate attachment regions 29 on a stiffening strip 26, so that no central loop section 15 is formed here as in the previously described embodiments. Nevertheless, even with such a configuration the high relative mobility can be realized, since here too, the connecting webs 5 can perform the unrolling or rolling movement according to the invention when a lateral force is introduced due to their geometry and highly flexible design. It would also be conceivable to arrange the two connecting webs 5 in this embodiment also on the outer leg 3 in two separate attachment areas 18.

Fig. 9 shows a further profile strip, the structure of the profile strip 1 Fig. 1 equivalent. There, however, a separate sealing lip 9 is provided, which is integrally formed on the underside of the outer leg 3 and ends in the mounting position in the shadow gap 23. As described, such a sealing lip is optional.

Fig. 10 shows a profiled strip according to the invention, the forth from the basic structure, as far as the design of the movement coupling, etc., in the example shown, the bar off Fig. 1 equivalent. However, here the outer Einputzsteg 7 is not disposed on the edge of the outer leg 3, but slightly offset inwards, so that there is a quasi-step shape. The fairing web 8 in turn is integrally formed on the outer side edge 3. Both are each provided here with an adhesion-improving coating 13 and can, as shown by way of example, be covered with a plaster layer 22.

The FIGS. 11-13 show three further embodiments that show various adhesion-improving coverings. Fig. 11 shows a profile strip 1, which may be any profile strip of the type described above. The adhesion-improving coating 13 here consists of a structured fabric 30, as indicated by the intersecting fabric threads. The fabric 30 is made of plastic, but may also be formed from textile fibers. The use of a glass fiber fabric is conceivable. Preferably, the fabric itself has an adhesive surface on which it is glued to the outside of the Einputzsteges 7. It is also conceivable, however, first to apply an adhesive layer to the outside of the outer web 7, to which the fabric is then glued. The fabric, which may be woven relatively coarse mesh, for example, so that they have an open structure as possible, in which the plaster layer dig into can, extends over the fairing web 8, so that this can be completely plastered. The material used to form the fabric 30 may be any, but care must be taken that the material is chemically resistant in that it can not be attacked by any ingredients contained in the plaster layer.

Fig. 12 shows a profiled strip 1 with an adhesion-improving coating 13 in the form of a glued, structured band 31. This band is for example made of plastic and embossed over the surface to form knob-like elevations 32 in the example shown. The tape 31 may be self-adhesive, thus having its own adhesive surface, via which it is glued to the outside of the Einputzsteges 7 and the fairing web 8. Also, alternatively, the respective outer side can be provided with an adhesive layer, on which the tape 31 is then glued. Instead of the knob-like elevations 32, it would of course also be conceivable to form recesses, that is to say to perforate the band 31 so as to structure the surface. Also longitudinal elevations or obliquely running elevations or grooves can be pronounced etc. The type of three-dimensional structuring is arbitrary. Also this plastic band, for example, a band of PVC, offers the possibility that the plaster layer firmly anchored. It is also conceivable, however, the use of a textile felt or a flocked, so very short, dense protruding fibers having tape.

Fig. 13 shows a connection profile strip 1, in which on the outside of the Einputzsteges 7 and the fairing web 8 particles 33 produce the surface structuring. The particles 33 are embedded in a carrier medium 34, for example a cured adhesive or a resin layer. This also results in a rough, textured surface to which the plaster adheres over a large area and safely. In the process, the carrier medium can first be brought to the outside, for example brushed or sprayed on, after which the particles 33, which are, for example, sand or quartz powder, are sprinkled. But it is also conceivable to mix these particles in the still viscous carrier medium and then apply the mixture and the Cure carrier medium. Instead of the sand or quartz flour particles, it would also be conceivable to apply glass or plastic or wood or metal particles for structuring.

Fig. 14 finally also shows a profiled strip 1, in which the coating 13 is formed by fibers 36 fixed in a carrier medium 35. The fibers 36 may be, for example, plastic or textile fibers. Although in Fig. 14 the fibers 36 are drawn relatively coarse, so they can also be very fine, so thin and short, so that a total of flocking forms, as in Fig. 14 is additionally shown by the very short fibers 36 '.

It should be noted at this point that the described different embodiments are of course not exhaustive. Thus, the various profiled elements 2 shown or configurations of the structure on the outer leg, etc., can be combined with arbitrary embodiments of the fastening section 4 as well as arbitrary configurations of the connecting webs 5 or their connection to the outer leg 3 or to the fastening section 4. Of course, embodiments of another form with regard to the arranged on the outer leg 3 webs or anchoring webs, etc. are conceivable. Also, the various strips can be provided with a lateral Abdecklasche. As an alternative to the adhesive coating, a three-dimensional surface structure can also be formed on the outer web sides themselves. Furthermore, instead of a foam tape with adhesive layer, the adhesive layer can be applied directly to the loop portion or the fastening portion.
