Abstract

The profile bar (1), especially for mounting frames at building window and door openings, has an outer leg (7) in the mounted position at the plaster which is extended to form the cladding bar (8). The extended bar unit carries a cladding (13) to bond the applied plaster or paint, or the surface is structured to give a plaster/paint bond. The cladding can be a structured ribbon or weave, with an adhesive, or a flocking of synthetic or textile fibers.

Description

The invention relates to a connection profile strip, in particular soffit connection profile strip, with a profile body with an outer leg and with this via connecting webs movably connected frame mounting portion for attaching the bar to a frame or rail component, in particular a door or window frame or a roller blind rail, via an adhesive surface, said the profiled body is provided at least partially, preferably completely concealing, facing web in the assembly position outer connecting web.

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 is sometimes a relative mobility of the component mounting portion, so 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, the outer leg and the component mounting portion connect, 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 rigid 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. Frequently, a substantially vertically projecting from this side web is provided on the outer leg, to which after the application of the plaster layer on the adjacent masonry or the like. the plaster layer connects. The bridge is thus visible in the mounting position, it forms a clean connection to the plaster layer. However, the region below the outer leg with the connecting webs and the component fastening section remains optically visible as well comprising, for example, the relatively thick foam adhesive tape. 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. The visibility of this area is therefore sometimes not appealing for visual reasons.

The invention is thus based on the problem of specifying a connection profile strip, which can be processed visually appealing.

To solve this problem is provided according to the invention in a connection profile of the aforementioned type that on the profile body in the mounting position outer Einputzsteg, which preferably protrudes vertically from the outer leg, is provided, which is formed extended to form the fairing web, the outside of the Einputzstegs and the cladding web is provided with a covering which improves the adhesion of a plaster or paint layer to be applied or with an adhesion-improving three-dimensional surface structure.

This fairing web, which is preferably arranged close to or at the edge of the outer leg, thus extends to some extent laterally of the intended 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 not too large, while with large moldings and joints, for example, 5 mm and more may remain. This remaining shadow gap, which are, however, kept as small as possible in the mounting position should, is visually appealing, so in the end, therefore, only the fairing web is to be seen as a straight-line visual element, which is visually appealing.

In this case, an outer Einputzsteg, which preferably protrudes vertically from the outer web, formed extended to form the fairing web. This web, which connects to the plaster layer as described in the assembly position, is now according to the invention extended downwards, so that the cladding web is formed in the immediate extension. In the assembly position so that a uniform surface is given, it remains only the narrowest possible shadow gap, from the lying below the outer leg area is no longer visible. This results in a very attractive, homogeneous appearance.

Furthermore, it can be provided that the exterior in the mounting position Einputzsteg on its outside with a the adhesion of a applied plaster or paint layer improving coating or serving for this surface structure, eg. B. is provided a roughening. It is a Einputzsteg provided, which is so even plastered, so in the mounting position is under plaster. It therefore 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. In order to ensure optimum adhesion of the plaster or a layer of paint, the outside of the plasterboard is provided with a corresponding adhesion-improving coating or structured three-dimensional. 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.

The cover web provided according to the invention can also be concealed in an optically appealing manner if, as is furthermore provided according to the invention, the cover web also bears the adhesion of the plaster surface to be applied. or color layer improving coating or such an adhesive structure is provided. In particular, if the Einputzsteg is extended and merges directly into the panel web, it is easily 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 strip is then completely gone 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. Example, a plastic or textile tape, or a glued fabric (eg., A glass fiber fabric) or on the type of flocking applied fibers, each 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. With regard to the used band or tissue or There are no restrictions on the fibers as long as the adhesion-enhancing 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 is carried out here by on or introduced particles, primarily quartz powder or sand is used, especially quartz powder or sand are alkaline resistant, which is advantageous in terms of applied 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.

According to an expedient development, the connection profile strip according to the invention is further distinguished by the fact that the connecting webs consisting of a deformable material are designed to be flexible and curved in such a way that they can be deformed in a rolling movement with a horizontal displacement of the fastening section relative to the outer leg. So it is characterized by highly flexible connecting webs, which thus consist of a very soft, elastic very easily deformable material, so that therefore the Connecting webs an acting movement or displacement force oppose 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 connection profile strip is characterized in that the highly flexible connecting webs are formed bent, 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 bent home, preferably bent outwards. 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. Movements of 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 a small, acute angle on the outer leg or the attachment portion, they are preferably to the outer leg and the attachment 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 the softest possible, elastic plastic or rubber material, are expediently produced together with the other components of the profile body, insofar as they are extruded from plastic, in a coextrusion process, thus also formed. This applies with respect to each embodiment of the invention the Anschlussprofilleite. It can be provided according to a first alternative of the invention that the connecting webs are part of a one-piece, arranged on the outer web loop, which forms the or at least a part of the fastening portion. In this embodiment, the strip is formed on the existing example of hard PVC outer web, for example, a very soft soft PVC integrally formed loop, which is virtually 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 lower-side adhesive layer, or it forms part of the attachment portion, on which part then a further strip or the like of harder material is formed, which then carries 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. If desired, an even greater strength or rigidity in the fastening section region can then be achieved by way of this stiffening strip, again made of rigid PVC.

In addition to the invention alternative with an integrally formed on the outer leg, highly elastic or flexible loop, it is also conceivable to arrange only the two connecting webs on the outer leg, and this to form the attachment portion at the other end to a side rail, which in turn preferably according to the rest of the profile body a harder material such as hard PVC is formed to bind. In this embodiment, in turn a hollow chamber 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, it is also possible, especially when forming a loop, to allow the connecting webs to merge into a connecting section, which is then integrally formed on the outer limb. 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 covered with a peelable protective tape, usually a silicone coated tape. 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.

a further embodiment of a connection profile strip according to the invention.

Fig. 1 shows a connection profile strip 1 according to the invention with a profile body 2 comprising an outer leg 3 and a component mounting portion 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, as provided, is formed of very soft, flexible soft PVC with low Shore hardness in a co-extrusion process. At the lining web 8, a cover strip 10 is projecting substantially at right angles thereto over a predetermined breaking point 11, here e.g. in the form of a material weakening, which carries an adhesive element 12, for example in the form of a double-sided adhesive tape (foam adhesive tape), which is glued to the top of Abdecklasche 10. 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.

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 a part of the component mounting section 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 hardness (eg Shore A ≤ 30) as low as possible 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 combination with the high flexibility of the connecting webs, realized by the material used and the low 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, which will be discussed below.

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. Obviously, the plaster layer 22 is also applied to the outside of the plasterboard 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 kept so narrow can be 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 bent geometry that a rolling movement takes place at a force in the horizontal direction. Obviously, the overlapping connecting web sections shift of the two connecting webs 5 in this case, they slide away one above the other, so that there is a total of a rolling or rolling-like 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. Also, a vertical movement in the range of several millimeters, depending on the distance from the component mounting portion to the outer leg 3, given, wherein 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 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. In contrast to the previously described embodiment, the adhesive layer 17 is applied here by way of example directly to the loop 14 or the loop section 15, and no foam tape is arranged 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 a plaster fabric 28 added, 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 because of entire structure below the outer leg 3 is slightly stronger 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, the high relative mobility can also be realized in such an embodiment, since here too, the connecting webs 5 can perform the unrolling or rolling movement according to the invention when a transverse 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, in which it is can 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 open structure as possible, in which the plaster layer can dig, also extends over the panel web 8 so that it 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 thin, 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. It is also conceivable, however, to mix these particles into the still viscous carrier medium and then apply the mixture and cure the 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 '.

Fig. 15 Finally, shows a further embodiment of a bar according to the invention, in which on the outer leg 3 compared to the connecting webs 5 much firmer, more stable connecting webs 37, a component mounting portion 4 forming stiffening strip 26 is provided with the adhered thereto foam adhesive tape 16 with the adhesive layer 17. Again, an adhesion-improving coating 13 of any kind is provided on the outer plaster web 7. Further shown by way of example is a holding or clamping section 27 (piping) inserted between the two webs 6, 7, with a plaster fabric 28.

Although not shown in the figures, there would also be the possibility, in a strip according to the invention on the outer web 7 no adhesion-improving coating applied, the web 7 so in the mounting position not under plaster lay. His front would then, as before, visible, they would connect to the plaster layer. However, it may be extended in the sense of the invention down to form the trim web 8.

It should be noted at this point that the described different embodiments are of course not exhaustive. Thus, the various profile bodies 2 shown or configurations of the structure on the outer leg, etc., can be combined with any desired configurations 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.
