Description

The invention relates to a connection profile strip, in particular a soffit connection profile strip, with a strip body with a first cross bar, at the top of which is provided at an angle to the transverse web side grooming ridge, wherein on the underside of the first crosspiece, a flexible connecting portion is arranged on which a second Cross bar is arranged, which is vertically and transversely movable relative to the first cross bar via the flexible connecting portion and on the underside of an adhesive tape or an adhesive coating is provided for connection to a third object, wherein the connecting portion extends only partially over the width of the two transverse webs.

Such connection profile strips, in particular soffit connection profile strips, serve to produce a transition of a wall to a third object, such as usually a frame part of a window or a door. The strip is adhered to the third article via an adhesive tape or adhesive coating. The opposite side of the bar with the plasterboard is plastered, that is, that a wall occupying the plaster layer is pulled up to this first crosspiece, the plaster layer is pulled off the side grooming ridge. Occasionally, at the first crosspiece, another, provided on the other web side Einputzsteg provided which provides an additional anchoring in this plaster layer.

In order to record relative movements between masonry respectively plaster layer and the frame member, without the risk that the connection of the plaster to the frame component breaks, the flexible connecting portion is provided, which allows the first cross bar and the second cross bar are movable relative to each other , both vertically and transversely to each other as to some extent often in the longitudinal direction. This means that any movements can be absorbed via the flexible connecting section.

Such a flexible connecting portion may be formed in the form of one or two connecting webs, which run from the first to the second transverse web and are made of a sufficiently soft plastic material. It is also known to form the connecting portion via a hollow, oval-sectioned hollow hose which is made of a flexible plastic material and which is firmly connected to both transverse webs. Since the transverse webs and the plaster web etc. are usually made of a relatively hard plastic, such as rigid PVC, it is readily possible to produce the flexible, also made of a plastic connecting portion in a common molding process, thus therefore the connection profile strip as 2K- Extrude component. The connecting portion may be, for example, made of soft PVC or a TPE (thermoplastic elastomer).

After adhering the connection profile strip to the frame component, the plaster layer is applied to the adjacent wall as described. The plaster is plastered right up to the strip, whereby, of course, the space behind the strip is plastered, so that there is no cavity. However, it may happen that plaster penetrates between the two transverse webs, after the connecting portion extends only partially across the width of the two transverse webs, so for example, the two elastic connecting webs are not entirely provided on the two transverse web ends, or the already described hollow, oval Hose does not extend all the way to the cross bar ends, whereby even then remains due to its oval shape, a space between the transverse webs, in which the plaster can penetrate. If a plaster penetrated between the two transverse webs now hardens, this can in extreme cases lead to the relative mobility of the two transverse webs to one another, which results from the connecting section, being restricted or even no longer being given. This means that the transverse webs can no longer move sufficiently or not at all transversely or vertically to each other, so that consequently the movement absorption capacity of the connecting portion is limited or no longer exists and any relative movements between plaster layer and frame member can not be included.

The invention is therefore based on the problem of specifying a contrast improved connection profile strip.

To solve this problem is provided according to the invention in a connection profile strip of the type mentioned that on the underside of the first crosspiece, in the region of the grout ridge opposite side, at least to the second crosspiece extending Abdecksteg is arranged over which the area between the two Cross webs and thus the flexible connection section is covered.

According to the invention, a covering web is formed or respectively provided on the first transverse web, which serves to cover the gap between the first and the second transverse web. It extends from the first crosspiece at least to the second crosspiece. Preferably, the cover web is brought laterally to the second transverse web respectively extends laterally to the second transverse web, either at a small distance or this slightly touching.

Consequently, the area between the transverse webs is covered by the cover web, so that it is ensured that no plaster can get between the two transverse webs. Since the cover web is not connected to the second crosspiece, therefore, the relative mobility of the two transverse webs is still given to each other as before.

The cover web itself may be formed of the same plastic as the first crosspiece, it may be formed of a softer plastic or as a hybrid component of a soft section and a harder section made of plastic, which will be discussed below. In any case, it is designed and positioned so that, in spite of the fact that it extends to the second crosspiece or even beyond, the relative movement of the two transverse webs to each other neither in the transverse direction nor in the vertical direction, or provided in the longitudinal direction the bar obstructed.

As already described, the connecting portion may be tubular or loop-shaped, that is, it is designed as a one-piece hose or loop portion. Alternatively, it can also be formed by means of two straight or curved, in particular outwardly curved connecting webs. Each of these embodiments means that there is still a sufficient distance or open gap between the two transverse webs, could enter the plaster disadvantageously, but this is prevented by the Abdecksteg invention.

Moreover, it is preferred if the cover web extends into or over the adhesive plane of the adhesive tape or the adhesive layer. The cover web thus runs into the adhesive plane or beyond. As a result, it not only has a capping function, but also, to a certain extent, a supporting function. If the bar plastered, so it may happen that when plastering the plaster layer is pressed against the bar so that it slightly tilted inwards with the Anputzschenkel and the first cross bar. This is opposed by a certain resistance beyond the cover web extending beyond the adhesive plane, since the cover web can easily be supported on the third object, that is to say the frame component. The Abdecksteg comes in this case to a double function.

It is preferred if the Abdecksteg consists of a flexible mounting portion, via which it is connected to the underside of the first crosspiece, and a subsequent to the mounting portion web portion, wherein the mounting portion is made of a softer material than the existing of a harder material web portion , About this training of two different hard plastic materials a certain flexibility of Abdeckstegs is ensured. He can easily tilt or pivot in the region of the flexible mounting portion. This is useful when the Abdecksteg extends slightly beyond the adhesive plane. For when gluing the cover web can easily buckle or swing in the area of the flexible mounting portion, so that the cover slightly dodges to the side, but with slight pressure on the Frame component rests. On the one hand, the gap between the transverse webs is still covered, on the other hand the cover web with the more stable web section is also somewhat supported on the third object, so that the described support function is given.

It is also useful if on the opposite side of the first crosspiece on the underside of a second Abdecksteg is arranged, which extends into or beyond the adhesive plane of the adhesive tape or the adhesive layer out, and from a flexible mounting portion, on the second Cover web is connected to the underside of the first crosspiece, and a subsequent to the attachment portion web portion, wherein the attachment portion is made of a softer material than the existing of a harder material web portion. In this embodiment of the invention, therefore, two cover webs are provided, which, although the first cover web is formed in this manner, are then made identical, ie in each case consist of a soft attachment portion and a harder web portion. The second cover web also has a covering function after it extends laterally of the second transverse web into the adhesive plane or beyond. This means that it prevents dirt or moisture from getting into the area between the two transverse webs. Since he is flexible in himself, he does not interfere with the relative mobility of the two transverse webs to each other.

The first and / or the second cover web or at least its or its web portion may extend obliquely to the second transverse web, or slightly curved outwardly. In particular, when the cover or the cover extend beyond the adhesive plane, it is ensured by an oblique or curved course in the mounting position that the one or more Abdeckstege pivot slightly further outwards.

In a further development, at the top of the first crosspiece, in the region of the side opposite the plastering web, a plastering web standing at an angle to the transverse web can be provided. This plasterboard serves the claws the connection profile strip in the plaster layer, what this - as well as the plaster bar on the opposite side - with lateral projections z. B. may be provided in a hook shape or the like. The Einputzsteg is preferred, as well as the Anputzsteg, perpendicular from the first transverse leg, they are preferably both formed directly on or close to adjacent to the outer edges of the first crosspiece. But they can also be at a different angle than 90 ° to the first transverse leg.

If such Einputzsteg provided, the first Abdecksteg can be arranged substantially in a vertical extension of the Einputzsteges on the underside of the crossbar. The same applies to the second cover web, which is preferably arranged substantially in a vertical extension of the Anputzstegs on the underside of the first crosspiece. Substantially vertical in this context means that a certain oblique course thereof is also covered, that is to say that the respective plastering web can also run away from the underside of the first transverse web at a slight angle or slightly bent from the very beginning.

The profiled body and the strip body with the grooming ridge, the first crosspiece and optionally the Einputzsteg and the second crosspiece and the or the grooming ridges or the web portions or of a harder material than the existing of a softer material connecting portion or the one or a softer Be material existing fastening sections. The harder material may be, for example, hard PVC, while the softer material is soft PVC or a TPE or the like.

Furthermore, on the profiled body in the region of the grooming ridge, a Folienanklebesteg tethered via a predetermined breaking point can be provided on which a cover, over which the window or door can be covered during plastering, can be attached. For this purpose, an adhesive tape or an adhesive coating may be provided on the upper side of the Folienanklebesteg, which is protected by a Abdeckschutzband which is removable. Such an adhesive tape may for example be a double-sided adhesive tape.

Further advantages and details of the invention will become apparent from the embodiment described below and with reference to the drawings. Showing:

a schematic representation, cut, a connection profile strip of a first embodiment,

Fig. 2

the connection profile strip Fig. 1 in the assembly position,

Fig. 3

a schematic diagram, cut, a connection profile strip of a second embodiment.

Fig. 1 shows a connection profile strip 1 according to the invention here in the form of a soffit connection profile strip. It has a strip body 2 with a first cross bar 3, on which, vertically projecting, a lateral plaster bar 4 is arranged, which has a plurality of inwardly projecting retaining projections 5, which serve to cling to a plaster layer, not shown.

In the area of the opposite side of the first crosspiece 3, a plastering web 6 is provided in the example shown, which likewise has a plurality of retaining projections 7 projecting on both sides, which also serve for clawing in the plaster layer.

On the underside 8 of the first crossbar 3, a flexible connecting portion 9 is provided, here in the form of an oval-shaped hollow tube 10 formed from a flexible plastic material such as flexible PVC. This tube 10 can also be referred to as a "balloon". The connecting portion 9 is fixed to the underside of the first crosspiece 3. With the opposite side it is attached to a second transverse web 11, on the underside of which, in turn, an adhesive tape 12, here a foam adhesive tape, is arranged with a bottom-side adhesive coating 13. About these Adhesive layer 13 and the foam adhesive tape, the attachment of the connection profile strip 1 takes place on a frame member.

In the area below the Einputzsteges 6, a first Abdecksteg 14 is provided, which extends from the bottom 8 away. It runs laterally past the second transverse web 11 and extends with its end beyond the adhesive plane of the adhesive layer 13. The Abdecksteg 14 consists of a flexible mounting portion 15, for example, again made of soft PVC or a TPE, with which flexible mounting portion 15 he is connected directly to the bottom 8. To the flexible mounting portion 15 includes a made of a harder material such as rigid PVC web portion 16, which then extends beyond the adhesive plane of the adhesive layer 13.

Obviously, the cover web 14 engages over the gap between the first and the second transverse web 3, 11, that is to say the space which is ultimately delimited via the flexible connecting section 9, in this case the flexible hollow hose 10. As can be seen, the connecting section 9 or the hollow hose 10 does not extend completely up to the transverse web ends, so that a sufficiently large open area between the two transverse webs 3, 11 would be provided on the strip side facing the masonry in the assembly position. In order to prevent that penetrates into this area when plastering the strip of plaster, which, if cured, the relative mobility of the two transverse webs 3, 11 would hinder each other, the Abdecksteg 11 is provided, just this area between the two transverse webs 3, 11th Covered and prevents penetration of plaster. This is necessary after the two transverse webs 3, 11 are movable relative to one another via the flexible or elastic connecting section 9 integrated between them, that is to say the flexible hose 10. They are, as shown by the two arrows, on the one hand transversely movable, on the other hand, but also vertically movable to each other. The central circle symbol indicates that a certain flexibility in the longitudinal direction of the bar can be given. These mobilities are fully maintained, even if the bar is completely plastered, since the cover web 14 clogging the gap between the two transverse webs 3 and 11 prevented with plaster. This also contributes to the given flexibility of Abdeckstegs 14 resulting from the soft mounting portion 15, which can easily deflect in a transverse or vertical movement.

On the opposite side of the first crossbar 3, virtually in approximately vertical extension of the plastering web 4, a second cover web 17 is provided, which is formed in the example shown according to the cover web 14. He is also connected via a flexible mounting portion 18 on the underside 8 of the first crosspiece 3. The fastening section 18 is adjoined by a web section 19 made of a harder material, which also extends beyond the adhesive plane of the adhesive layer 13 here. Again, the attachment portion 18 may be, for example, of soft PVC and the web portion 19 of hard PVC. This is obvious, of course, if the strip body 2 and the second crossbar 11, for example, made of rigid PVC and the flexible connecting portion 9 is made of soft PVC.

Furthermore, a Folienanklebesteg 20 is provided which is fastened via a predetermined breaking point 21 on the strip body 2. This is used to attach a cover, for which purpose an adhesive tape 27 or an adhesive layer can be arranged on its upper side, on which or a film can be attached.

Fig. 2 shows in the form of a schematic representation of the mounting position of the connection profile strip 1. The connection profile strip 1 is glued to the adhesive tape 12 via the adhesive layer 13 on a frame member 22, for example a window frame. Since, as described, the two covering webs 14 and 17 extend beyond the adhesive plane of the adhesive layer 13, they come in contact with the top of the frame component 22 when the connecting profile strip 1 is glued to the frame component 22. In the bonding process, the two covering webs 14 and 17 can over the two flexible Fasten mounting portions 15 and 18 slightly outward. So they are at a low pressure on the top of the frame profile 22.

Now, if the plaster layer 23 is applied to the masonry 24, then this plaster layer 23 can be drawn without problems in the area behind the plasterboard 6, without the risk that the plaster in the gap 25 between the two transverse webs 3 and 11 arrive can. As can be seen, this area 25 is completely covered and protected by the cover web 14.

Fig. 3 finally shows a second embodiment of a connection profile strip 1, wherein the same reference numerals are used for the same components. The connection profile strip 1 in turn comprises a strip body 2 with a transverse web 3 and a plastering web 4 as well as here a Einputzsteg 6, which are executed in the same way as the corresponding webs Fig. 1 ,

Also provided is a second transverse web 11, wherein between the transverse webs 3 and 11, a flexible connecting portion 9 is provided here, but here via two separate, outwardly bent and made of a flexible or elastic material connecting webs 26 is formed. These curved connecting webs 26 allow a transverse and vertical movement and a certain longitudinal movement of the two transverse webs 3 and 11 relative to each other, as well as the hollow tube 10 from Fig. 1 allows.

At the bottom 8 of the first crossbar 3, below the Einputzsteges 6, a Abdecksteg 14 is also provided here, but here consists only of a single material, for example, from the same material as the strip body 2, so for example made of rigid PVC. It extends in the direction of the second crosspiece 11 and laterally past it a little beyond. In any case, it is somewhat distanced from it, so that it does not obstruct the relative mobility of the two transverse webs 3 and 11 relative to each other during any transverse or vertical movement. He therefore also covers the gap 25 between the two transverse webs 3, 11 from. Since he does not have the adhesive plane of the As a result, the adhesive layer 13 of the adhesive tape does not have to have any inherent flexibility, unlike the cover web 14 Fig. 1 Because he is not in the mounting position on the frame member 22.

Furthermore, a second cover web 17, which is embodied here in exactly the same way as the corresponding cover web 17, is also provided here Fig. 1 , Finally, a Folienanklebesteg 20 is provided, which is also carried out as the Fig. 1 ,

Again, the strip body 2 with all its webs together with cover web 14 and the second cross bar 11 and the web portion 18 may be made of rigid PVC, whereas the two flexible connecting webs 26 are made for example of soft PVC.

The invention is not limited to the illustrated embodiments. Of course, it would be possible, instead of the hollow tube 10 in the embodiment according to Fig. 1 two curved connecting webs 26 as in the embodiment according to Fig. 3 provided. Similarly, the two connecting webs 26 according to Fig. 3 through a hollow tube 10 according to Fig. 1 be replaced. Also, it is not mandatory that a second cover web 17 is provided. Furthermore, the arrangement of the plastering and Einputzsteges respectively their concrete geometry may also be different. Thus, the Einputzsteg can be positioned further to the center or still completely to the outside, as he can also be completely eliminated. The arrangement or geometry of the Folienanklebesteges 20 may be of different types.
