Description

The present invention relates to a plaster strip for placement on a building transition between a window or door frame formed as a first building component and a second building component, in particular a thermal insulation and / or a plaster layer, the use of a double-sided adhesive foam tape in a plaster molding for placement on such a building transition and a building transition with such a plaster molding.

Cleaning strips are known in numerous embodiments. Particularly typical embodiments are plaster strips, which are attached to a window or door frame and allow a plastering of the plaster layer to the plaster molding instead of up to the window or door frame. Thereby, the thermal insulation and / or the plaster layer is decoupled from the window or door frame, which ensures typically occurring, large temperature fluctuations that no damage, for example by cracks or crumbling, at the end of the plaster layer is formed and that the plaster layer at the end intact remains, as well as that the transition between window or door frame and insulation and / or plaster layer is permanently securely sealed.

From the DE 102 42 615 A1 Such a plastering strip is known, which is adhered by means of a foam adhesive tape to a window frame.

In experiments with such cleaning strips has been shown that when such plaster strips come in the installed state, for example, with a flame of a Bunsen burner in contact, such plaster strips are inflamed after some time.

Although the risk of fire in this position is not very high, because the adjacent components, in particular the plaster layer and / or the window or door frame, which is often made of plastic, can not be inflamed, but there is a need, the risk of fire on the side of the plaster molding to lower as much as possible.

It is therefore an object of the present invention to provide a plaster molding and a corresponding building transition, in which the risk of ignition is reduced to a minimum, while maintaining the tightness and freedom from damage at the cleaning end.

This object is solved by the subject matter of the independent patent claims. Advantageous developments emerge from the dependent claims.

According to a first embodiment variant, a plastering strip according to the invention for placement on a building transition between a first building component designed as a window or door frame and a second building component, in particular a thermal insulation and / or a plaster layer, comprises a plastic base body; and a double-sided adhesive foam adhesive tape bonded to one side by adhesive bonding to the base body and provided with an adhesive layer on another side and intended for adhesive bonding with the first component of the building. The double-sided adhesive foam tape has a base material whose behavior in case of fire in the fire protection class B1 "flame retardant" according to DIN standard 4102-1 or in the fire protection class B2 "normal flammable" according to DIN standard 4102-1. The double-sided adhesive foam tape has a closed-cell foam and a flame retardant.

According to a second embodiment variant, a plastering strip according to the invention for placement on a building transition between a first building component designed as a window or door frame and a second building component, in particular a thermal insulation and / or a plaster layer, comprises a base region; a plastering area intended for plastering into the plaster layer and / or for firm connection with the thermal insulation; a double-sided adhesive foam adhesive tape bonded to one side by adhesive bonding to the base portion and to another side by adhesive bonding to the rendering area; and an additional adhesive tape, in particular made of foam, which is adhesively bonded to the base region by means of one side and which is provided with an adhesive layer on another side and intended for connection to the first component of the building. The base area and / or the plastering area have a base body made of plastic. The double-sided adhesive foam tape has a base material whose behavior in case of fire in the fire protection class B1 "flame retardant" according to DIN standard 4102-1 or in the fire protection class B2 "normal flammable" according to DIN standard 4102-1. The double-sided adhesive foam tape has a closed-cell foam and a flame retardant.

The inventor of the present patent application has found that the main material, ie the material of the body of the plaster strip is crucial for the risk of ignition of a plastering strip in the installed state, because this is so largely covered by the plaster layer, but rather the intermediate layer between the plaster strip and the Window or door frame plays a crucial role for this, since it is arranged in the gap between window or door frame and insulation and / or plaster layer and accessible from the outside of the building and therefore exposed in case of fire a possible fire stress.

According to another, the invention is based knowledge, the main material of the plaster strip is usually made of flame retardant material, in particular made of rigid PVC, however, is just that part of the plaster strip, which is accessible from the outside and in case of fire a flame and thus a fire is exposed, namely the adhesive tape, with which the plaster molding is glued to the window or door frame, made of a material which is easily combustible.

According to a basic idea of the present invention, the behavior of the foam adhesive tape in case of fire is reduced at least to fire protection class B2 "normally flammable" according to DIN standard 4102-1. As a relevant state of DIN standard 4102-1, the edition of May 1998 is considered.

This ensures that the properties and advantages of the plaster molding are kept unchanged and that in particular the simple sticking of the plaster molding to the first building component and the movement absorption of the foam adhesive tape are still retained.

Due to the fact that according to the invention the behavior of the foam adhesive tape in case of fire is reduced to at least fire protection class B2 "normally flammable" according to DIN standard 4102-1, the risk of ignition of the foam adhesive tape is significantly reduced. This also reduces the risk of fire of the plastering strip as a whole.

This is important both for the delivery condition and for the installed condition of the plastering strip, as well as for the installation phase of the plastering strip, because even during the installation phase, a fire with a different fire effect can occur. The fact that according to the invention, the behavior of the entire foam adhesive tape, and not only partially against lateral flames, in case of fire at least on the fire protection class B2 "normal flammable" according to DIN standard 4102-1 is reduced and by reducing the risk of ignition of the plaster bar Overall, the emergence or the spread of a fire can be effectively counteracted during the installation phase.

In the first embodiment, the risk of ignition of the plaster strip is reduced to a minimum, because the components of the plaster strip, which are accessible after installation of the same at the building transition and plastering done from the outside and can be achieved in the event of fire from a flame, namely the foam tape and the underside of the body, both each have a base material whose behavior in case of fire at least in the fire protection class B2 "normal flammable" in the body even mostly in the fire protection class B1 "flame retardant" falls and also because the double-sided adhesive foam tape has a flame retardant ,

Also in the second embodiment, the risk of ignition of the plaster strip is reduced to a minimum, because the components of the plaster strip, which are accessible after installation of the same at the building transition and plastering done from the outside and can be achieved in the event of fire from a flame, namely the outward Sides of the adhesive tape, the base area and the foam adhesive tape and possibly the underside of the Anputzbereichs, each having a base material whose behavior in case of fire at least in the fire protection class B2 "normal flammable", in the body even mostly in the fire protection class B1 "flame retardant" falls and also because the double-sided adhesive foam tape has a flame retardant.

In the plaster moldings according to the invention according to the first and second embodiment, the risk of ignition compared to conventional plaster moldings is thus significantly reduced, without any deterioration of the other properties of the plaster moldings.

It should be noted at this point that, instead of the fire protection classes B1 "flame retardant" and B2 "normally flammable" used in accordance with the invention, the DIN standard 4102-1 also includes the corresponding classes for fire behavior from the European standard EN13501-1 can be used as a reference.

The foam adhesive tape is not a one-sided adhesive tape, but a double-sided adhesive foam tape, which is provided on its opposite sides in each case with an adhesive layer.

In the plaster strip, the first embodiment variant, the double-sided adhesive foam adhesive tape is adhesively bonded by means of the adhesive layer on one side with the base body, and by means of the adhesive layer on the other side, which in the delivery state usually with a covering, for example a cover Paper strip, is covered, intended for adhesive bonding with the first component of the building.

In the installed state, the plaster strip, first embodiment, by means of this adhesive layer on the other side of the double-sided adhesive foam tape with just this component of the building is adhesively connected.

In the plaster molding, second embodiment variant, the double-sided adhesive foam adhesive tape by means of the adhesive layer on one side adhesive to the base area and by means of the adhesive layer on the other side is adhesively bonded to the Anputzbereich.

The foam adhesive tape of the invention usually according to the first and second embodiment, a closed-cell foam on.

This is a significant difference from conventional single-sided PUR sealing tapes, which are usually of open-cell foam, because they are impregnated with impact rain and impregnation is only possible with open-cell, but not closed-cell foam materials.

A conventional, single-sided adhesive PUR sealing tape provides no bonding and thus no connection with respect to the building component to which it rests, in the diction of independent claim 1, no bonding and thus no connection with the first building component ago.

The fact that the foam adhesive tape has a closed-cell foam in the first and second embodiment variant of the plaster molding according to the invention, it is inherently tight against moisture or water, For example, against the ingress of rain or driving rain or - in the case of horizontal installation of the plaster molding - against stagnant water.

Moisture or water can not get inside the double-sided adhesive foam tape because the cells are closed and do not allow moisture or water to enter.

Thus, the double-sided adhesive foam tape is so to speak waterproof and moisture-tight. No water or moisture is absorbed, as is the case with conventional single-sided open-cell PUR sealing tapes.

The fact that the foam of the double-sided adhesive foam tape is closed-cell, there is also only a very limited expansion possibility and a movement recording, which is usually in the range between 1 mm and 2 mm, which is sufficient for most applications and what an additional distinction from conventional one-sided adhesive and open-cell PUR sealing tapes.

According to a first embodiment of the first embodiment of the plaster strip according to the invention, the base body has a base region made of plastic and a plastering area made of plastic, which is intended for plastering into the plaster layer and / or for firm connection with the thermal insulation.

According to a further embodiment of the first embodiment of the plaster strip according to the invention, the base region and the plastering area are integrally formed. The double-sided adhesive foam adhesive tape is adhesively bonded to one side by adhesive bonding to the base area.

According to a further embodiment of the first embodiment of the plaster strip according to the invention, the base area and the plastering area are formed separately from one another such that a relative movement between the base area and the plastering area is made possible by means of a guide connection, if appropriate after separating a strip-shaped protective strip.

According to an embodiment of the first and the second embodiment of the plaster strip according to the invention, the base area and the plastering area are connected to each other via a flexible material section, which allows a relative movement between the base area and the plastering area.

According to one embodiment of the second embodiment of the plaster strip according to the invention, the base region is formed as a base wall. The plastering area may have a surface area wall section that is parallel to the base wall. The additional adhesive tape may be secured by adhesive bonding to an underside of the base wall. The double-sided adhesive foam adhesive tape may be bonded to one side by adhesive bonding to the top of the base wall and to another side by adhesive bonding to the underside of the rendering area wall portion. The flexible material portion may connect an end portion of the base wall to an end portion of the plastering area wall portion at a position in front of the foam adhesive tape, and allow relative movement between the base portion and the plastering portion.

According to a further embodiment of the second embodiment variant of the plaster strip according to the invention, the plastering area at the front of its plastering area wall section furthermore has a plastering area end section directed in particular obliquely downwards. The grooming area end portion can, seen from the front, cover the flexible material portion.

According to a further embodiment of the second embodiment of the plaster strip according to the invention, the additional adhesive tape also has foam, and the behavior of the additional adhesive tape of foam in case of fire is also at least reduced to the fire protection class B2 "normally flammable" according to DIN standard 4102-1. The additional adhesive tape has all the advantages and embodiments described herein with respect to the double-sided adhesive foam adhesive tape. These are not explained again to avoid repetition.

The following embodiments relate to both the first and the second embodiment of the plaster strip according to the invention.

The plastering area may also have an upwardly projecting, along the plaster strip extending Einputzsteg. At the plastering area can continue to be provided upwardly projecting, to be embedded in the plaster reinforcing fabric section. The reinforcement fabric section to be embedded in the plaster can be fastened to the plasterboard.

The plaster molding strip can furthermore have a strip-like protective tongue which is connected to the base area or to the plastering area via a break-off material bridge of lesser thickness.

According to one embodiment, the closed-cell foam of the double-sided adhesive foam adhesive tape is formed so that the walls between the individual cells are completely closed.

According to another embodiment, the closed-cell foam of the double-sided adhesive foam adhesive tape has a density which is in the range> 20 kg / m ³ and <100 kg / m ³ . By comparison, expanding open-cell, single-sided adhesive PUR sealing tapes have a density between 180 and 540 kg / m ³ when installed in the compressed state. Thus, in this embodiment, the density of the double-sided adhesive foam adhesive tape according to the invention is significantly reduced in contrast.

According to another embodiment of the present invention, this density range for the foam material of the double-sided adhesive foam adhesive tape refers to the installed state of the plaster molding.

According to a further embodiment, the double-sided adhesive foam adhesive tape has a material thickness / thickness which is in the range> 2 mm and <10 mm, and a movement absorption capacity of at least 1 mm in the material thickness direction.

According to a further embodiment, the double-sided adhesive foam adhesive tape has a width which is in the range> 6 mm and <20 mm.

The inventor of the present patent application has found that a double-sided adhesive foam tape whose density falls within the claimed range and which has a material thickness that falls within the claimed range represents an optimum compromise between good fire performance and good movement absorption.

The inventor has further found that the thicker and denser the foam tape is, the better the fire performance is formed, and on the other hand, it does not make sense for the foam adhesive tape to be too dense for the use of a foam adhesive tape in a render Select foam material, since then the movement is too low, because a foam tape with dense foam material only an insufficient movement absorption holds.

The foam material for the double-sided adhesive foam tape is therefore ideally foamed so much that the requirements for the movement absorption are met, but at the same time not so strong foamed, so it still falls at least in the fire protection class B2 "normal flammable".

The inventor has further found that a minimum thickness of 2 mm and a minimum width of 6 mm are advantageous for the double-sided adhesive foam adhesive tape. At the top, the thickness of the double-sided adhesive foam tape should not exceed 10 mm and the width thereof should not exceed 20 mm.

According to a further embodiment, the base material of the double-sided adhesive foam adhesive tape comprises polyolefins, in particular polyethylene or polyols.

According to a further embodiment, the double-sided adhesive foam adhesive tape is designed as a non-expanding foam.

Expanding foam adhesive tapes are usually held in delivery condition by a locking means in a compressed state. This locking means is released during installation of the plaster molding. Subsequently, the foam adhesive tape expands and then has a thickness / material thickness, which is usually a multiple of the thickness / material thickness in the delivery condition.

In the case of the double-sided adhesive foam adhesive tape according to the invention, on the other hand, the thickness / material thickness in the delivery state essentially corresponds to the thickness / material thickness in the installed state. A difference usually only results from the movement absorption, for example by a reduction in the distance between the first and second building component.

The behavior of the double-sided adhesive foam tape in case of fire can be reduced to the fire protection class B1 "flame retardant" according to DIN standard 4102-1.

According to a further embodiment, the plastering area further comprises an upwardly projecting, along the plaster strip extending Einputzsteg on which an upwardly projecting, to be embedded in the plaster Armierungsgewebe section is provided. This reinforcement fabric section is designed in particular as a glass fiber fabric whose coating and / or finish has a flame retardant.

According to a further knowledge of the inventors, the reinforcing fabric section of conventional plaster moldings is often provided with a coating which is also inherently highly flammable. This has not been respected so far, since only the basic material of the plasterboard and its flammability were in focus. Therefore, the inventor has found that by providing the coating and / or the finish of the formed as a glass fiber fabric reinforcing fabric portion of the grout with a flame retardant and the behavior of the reinforcing fabric section in case of fire to the fire protection class B2 "normal flammable" or the fire protection class B1 "flame retardant" can be reduced, which has a corresponding effect on the classification of the plaster bar overall in just this fire protection class.

This is important both for the delivery condition and for the installed condition of the plastering strip, as well as for the installation phase of the plastering strip, because even during the installation phase, a fire with a different fire effect can occur. Due to the fact that according to the invention the behavior of the reinforcing fabric section in case of fire is reduced to at least the fire protection class B2 "normally flammable" according to the DIN standard 4102-1 and by the reduction of the risk of fire of the plastering strip as a whole, the emergence or spread of a fire also during the installation phase, in which the Armierungsgewebe section is partially accessible over a large area for a flame, effectively counteracted.

The flame retardant of the foam adhesive tape can reduce the behavior of the foam adhesive tape in case of fire to fire protection class B2 "normally flammable" or to fire protection class B1 "flame retardant" according to DIN standard 4102-1.

When reference is made below to flame retardant (s), it is to be understood that these are both the flame retardant (s) provided on the double-sided adhesive foam tape and the flame retardant (s) with which it is used the coating and / or the Finishing of optionally existing, designed as a glass fiber fabric Armierungsgewebe section can be provided.

The flame retardant may be formed as a halogenated flame retardant, a nitrogen-based flame retardant, an organophosphorus flame retardant, or an inorganic flame retardant.

The flame retardant may be formed as an additive flame retardant, which is introduced as an additive in the base material of the foam adhesive tape, in particular in the polyethylene base material of the foam adhesive tape, in particular in its pores.

The flame retardant may be a halogenated flame retardant selected from the group of TCPP, TDCP, TBBA, TBBPA, chloroparaffins and polyolefins.

The flame retardant may be formed as a non-halogenated flame retardant selected from the group consisting of RDP, BDP, aluminum hydroxide, magnesium hydroxide and trialkyl phosphate.

The flame retardant may be in the form of phosphoramidates or as a polymer FR, HBCD or DOPO (9,10-dihydro-10-oxa-phosphaphenatrenoxoid).

The invention also relates to the use of a double-sided adhesive foam adhesive tape in a plaster molding according to the first embodiment for placement on a building transition between a designed as a window or door frame first building component and a second building component, in particular a thermal insulation and / or a Putzschicht, which has a plastic body, to reduce the behavior of the foam adhesive tape in case of fire to the fire protection class B2 "normal flammable" according to DIN standard 4102-1: 1998 or to the fire protection class B1 "flame retardant according to DIN standard 4102- 1: 1998; wherein the double-sided adhesive foam adhesive tape is adhesively bonded to the base body on one side and provided with an adhesive layer on the other side and for adhesive bonding to the first building component; the double-sided adhesive foam adhesive tape Grundma In case of fire, its behavior in fire protection class B1 "flame retardant" in accordance with DIN standard 4102-1 or in fire protection class B2 "normal Flammable "according to DIN standard 4102-1 falls; wherein the double-sided adhesive foam tape has a closed-cell foam and a flame retardant.

The first plaster strip 2, the second plaster strip 26, and the third plaster strip 68 are described below as representative of any plaster strips, they are characterized by a constant over their entire length profile cross-section. The base area 4, the plastering area 10 and the strip-shaped protective strip 22 of the first plastering strip 2, the base area 28 (without foam adhesive tape 32), the displaceable front area 40 and the strip-shaped protective strip 60 of the second plastering strip 26, and the base area 70 (without foam tape). Adhesive tape 74 and 76), the plastering area 72 and the strip-shaped protective strip 86 of the third plaster strip 68 can be produced inexpensively by extrusion and form extruded parts.

The FIGS. 1 . 2 and 3 show the plaster strips 2, 26 and 68 respectively in the delivery state, in which the strip-shaped protective flap 22, 60 and 86 has not yet been separated.

In the Fig. 1 The first plastering strip 2 illustrated by way of example comprises a base region 4 and a plastering area 10 with a reinforcement fabric section 18 and a strip-like protective strip 22.

The base region 4 and the plastering area 10 are integrally formed with each other, so that the present plaster strip 2 can also be referred to as a one-piece plaster strip 2.

The strip-shaped protective tab 22 is connected by means of a break-off material bridge 24 with a cleaning end side 14 of the plastering area 10. The strip-shaped protective flap 22 still has a spacer web which, in the assembled state of the plastering strip 2, can rest on the outside of a first building component.

The base region 4, the plastering area 10 and the strip-shaped protective strip 22 have been produced jointly by way of extrusion.

The base region 4 is in this case of a in Fig. 1 horizontally extending base wall 6 and a fixed thereto, double-sided adhesive foam tape 8, which will be described in more detail below and which is intended for attachment to a first building component, namely a window or door frame.

The plastering area 12 is formed by the outside of the leg support 12, by the cleaning end side 14 directed away from the window or door frame, and by the reinforcing fabric section 18.

At the bottom, the first plaster strip 2 has a stepped course, the underside of the plaster end 14 is based on the installation situation, closer to the window / door frame as the bottom of the base wall. 6

The reinforcement fabric portion 18 is presently connected to the Wegragschenkel 12 by means of a welded joint 20.

The cleaning end side 14 directed away from the window or door frame and the surface of the support leg 12 directed by the thermal insulation in the direction of the opposite window or door frame side are provided with a channel profiling 16 for improving the adhesion of the plaster.

On the construction site, the plaster strip 2 is first cut to the appropriate length predetermined by the dimensions of the window or door opening and then attached to the transition between the window / door frame and thermal insulation by the plaster strip 2 with its base region 4 being inserted into the gap between window and door frames. or door frame and insulation is inserted so that the plaster strip 2 rests with the top of its base wall 6 on the gap-side end of the insulation, rests with the back of their Wegragschenkels 12 on the outside of the insulation and with the double-sided adhesive foam tape 8 on the surface of the Window or door frame is glued.

After overstretching the window with window frame or the door with door frame with a film which is attached to the strip-shaped protective flap 22, in particular glued, the plastering takes place. In this case, if necessary, after prior application of a filler behind the reinforcing fabric section 18, a reinforcing fabric section 18 and the plastering area 10 applied to a plaster removal edge plaster layer applied, which is essentially formed by the end of Putzendseite 14, to which the strip-shaped protective flap 22 connects. The strip-shaped protective flap 22 is broken off after the plastering and removed.

The double-sided adhesive foam tape 8 may have a certain expansion and compression ability to compensate for changes in the distance between the bottom of the base wall 6 and the surface of the window or door frame within certain limits, which ensures a good seal under changing conditions.

In the Fig. 2 by way of example, second plastering strip 26, like the first plastering strip 2, has a base region 28 which can be fastened to a section on a first building component, in particular a window or door frame, via a plastering area 40, which in the present case is designed as a displaceable front region 40. to which a reinforcing fabric portion 64 is attached and which is intended for embedding in a plaster layer together with the reinforcing fabric portion 64, as well as a strip-shaped protective tab 26th

In the strip-shaped protective tab 60, the adhesive layer applied on the outside is now recognizable, it is connected via a break-off material bridge 62 both to the base region 28 and to the plastering area 40, otherwise it is in alignment with the strip-shaped protective flap 22 Fig. 1 and will not be explained again below.

Unlike the integrally formed first plastering strip 2, the second plastering strip 26 is now formed in two parts, with a base region 28 and a movable plastering area 40.

The base region 28 comprises a base wall 30 with a foam adhesive tape 32 attached to its underside, which will be described in more detail below and which, with its underside in the assembled state of the plastering strip 26, sealingly bears against the window or door frame and is glued thereto.

At the right outer end of the base wall 38, a protective lip, not shown here, may extend downwards, which may be formed of a softer flexible plastic material and thus may have a certain flexibility. Such a flexible protective lip may rest against the surface of the window or door frame when the second plaster molding 26 is installed, at a position outside the double-sided adhesive foam tape 32, and thus reliably prevents moisture from being spread to the double-sided adhesive foam tape 32 can get. The protective lip can in particular together with the base wall 30 and the following even closer explained guide extension 36, are co-extruded with the plastering area 40 and the strip-shaped protection tab 60.

A guide extension 36 protrudes upward from the base wall 30 and is formed integrally therewith. This guide extension 36 comprises an uppermost widened end head 38 arranged at the top, an extension wall area of lesser wall thickness underneath and a continuation wall area of further reduced wall thickness forming the connection to the base wall 30.

The displaceable plastering area 40 is divided into an uppermost arranged Wegragschenkel 36, an adjoining receiving space 42 with the inside thermal insulation plant side 48 and outer plaster side 54, wherein the Wegragschenkel 46 has an inner plaster side 50 and an outer plaster side 54, and in one at the bottom outer end of the receiving space 42 attaching and outwardly extending Putzendseite 56th

The receiving space 42 is dimensioned such that the front end of the end head 38 with completely in the receiving space 42 Führungsfortsatz 36 and thus upon contact of the rear end surface of the side walls of the receiving space 42 at the front of the base wall 30 at a small distance from the upper wall of the receiving space 42nd is positioned. At the lower end of the inner sides of the receiving space 42, opposite guide projections 44 abut each other and extend so far inwardly, with respect to the symmetry axis of the receiving space 42, that they receive and guide the guide projection 36 therebetween. In the illustrated position of the guide extension 36, the guide projections 44 engage in the lowermost region of the guide extension 36 with reduced wall thickness and hold this guide extension 36 and thus the entire base region 36 with respect to the displaceable plastering area 40 in the minimum displacement position. The guide projections 44 can consist of a plastic material which is softer than the material of the displaceable plastering area 40.

If one imagines that the break-off material bridge or the break-off material bridges 62 of the base region 28 and of the displaceable plastering region 40 are severed to form the strip-shaped protective flap 60, the brushing region 40 can be displaced relative to the base region 28, up to a maximum Displacement position in which the guide projections 44 abut the end head 38. This allows movements between thermal insulation / plaster layer and window / door frames are compensated in a particularly advantageous manner.

From a central region of the upper wall of the receiving space 42, the upper Wegragschenkel 46 extends upward. The inner plaster side 50 and the outer plaster side 52 of the Wagragschenkels 46, the outer plaster side 54 of the outer wall of the receiving space 42 and the Putzendseite 56 are provided with cleaning grooves 58 to increase the surface to which the plaster adheres, and thus a better To create connection with the plaster. This channel profiling 58 may, as in Fig. 2 can also extend over the front wall of the receiving space 42.

On the outer plaster side 52 of the Wegragschenkels 46 is an in Fig. 2 attached to the forwardly extending Armierungsgewebe section 64, by means of a welded joint 66th

When installing the second plaster strip 26 no gap between thermal insulation and window / door frame must be present.

On the construction site, first the plaster strip 26 is cut to the appropriate, predetermined by the dimensions of the window or door opening length and then attached to the transition between window / door frame and insulation by applying the heat insulation plant side 48 to the insulation and with applied to the double-sided adhesive foam tape 32 to the window / door frame and glued. Thereafter, the protective film is stretched over the window or door frame and fixed to the adhesive layer of the strip-shaped protective flap 60. This is followed by the plastering of the plastering area 40, optionally after previously applied putty past the reinforcing fabric section 64. This putty can fill in particular the space between the outside of the thermal insulation and the reinforcing fabric section 64. When brushing the plaster layer extends either over the entire, provided with channel profiling 58 area of the plastering area 40 or, if filler has been applied, on the outer plaster sides 52, 54 and the cleaning end 56 to Putzendkante, through the end of Putzendseite 56th is defined.

After the plastering has taken place, the strip-shaped protective strip 60 can be removed by severing the break-off material bridges 62, for example by hand, optionally cutting the ends.

By severing the break-off material bridge 62, which has previously held together the base region 28 and the displaceable plastering area 40 via the strip-shaped protective strip 60, the displaceable plastering area 40 is now decoupled from the base region 28 and can pass through the construction with guide extension 36, end cap 38, and receiving space 42 with guide projections 44 move relative to the base wall 30, and thus compensate for movements between thermal insulation and plaster layer and window / door frame.

The second plastering strip 26 is a two-part plastering strip described by way of example in which two regions 28 and 40 can be displaced relative to one another in order to be able to compensate for movements between thermal insulation / plaster layer and window / door frame.

The invention also covers other two-part plaster moldings, in particular also two-part plaster moldings which are at least partially inserted into a gap between the thermal insulation and the window / door frame.

In this case, screed strips, in which the base region 28 and the plastering area 40 are connected to each other, for example by means of a flexible material region, a so-called loop, considered as one-piece plaster moldings. Plaster strips in which the base area 28 and the plastering area 40 are not connected to each other, however, are considered as two-piece plaster strips.

In the Fig. 3 by way of example, third plaster strip 68 comprises a base region 70, a plastering region 78 with a reinforcing fabric section 90 and a strip-shaped protective strip 86.

The base portion 70 is formed in the form of a base wall. The plastering area 72 comprises a plastering area wall section 78 which is arranged parallel to the base wall of the base area 70 and approximately the same width as this, a building exterior side plaster end portion 82 which attaches to the inside of the plaster area wall portion 78 and the down, Thus, in the direction of the window or door frame is bent, and one of the Anputzbereich wall section upwardly projecting Wegragschenkel 80th

The base area 70 and the plastering area 78 are formed separately from each other. It is thus a two-part plaster molding strip in which the base region 70 and the plastering region 72 can be displaced relative to each other in order to move between heat insulation / plaster layer and window / door frame to compensate.

The strip-shaped protective flap 86 is in turn connected by means of a break-off material bridge 88 with the cleaning end side section 82. The strip-shaped protective tab 86 may in turn have a spacer web, not shown here, which may abut in the assembled state of the plaster strip 68 on the outside of the window or door frame.

The base area 70, the plastering area 72 and the strip-shaped protective strip 86 have been produced jointly by way of extrusion.

The plastering area 72 comprises the fixing side located on the left of the projection leg 80 and the plastering surface located on the right of the projection leg 80.

The stipulation page is thereby in particular of the in Fig. 3 left side of the Wegragschenkel 80 and from the in Fig. 3 formed top of the left of the Wagragschenkel 80 located portion of the plastering area wall portion 78. It is easy to imagine that a thermal insulation is applied to the corner angle thus formed.

The plaster side is from the in Fig. 3 the outside of the Wegragschenkels 80, from the window or door frame directed away from the cleaning end face 84, including the right, ie located outside the Wagragschenkels 80 portion of the Anputzbereich- wall portion 78 formed.

Like in the Fig. 1 Thus, even with the third plaster strip 68, in turn, a reinforcing fabric section 90 is fastened by means of a welded connection 92 to the projection leg 80, in particular on the outside thereof. The extension direction of the reinforcement fabric portion 90 is parallel to the extension direction of the Wegragschenkels 80th

The projection leg 80 is arranged at a width position to the right of the center of the plastering area wall section 78, in particular approximately to two-thirds of the width of the plastering area wall section 78.

The base wall of the base portion 70 and the plaster area wall portion 78 of the plaster area 72 are formed by a double-sided adhesive foam tape 74 connected. This is glued in particular with its lower adhesive side with the upper side of the base wall of the base region 70 and with its upper side with the underside of the plastering area wall section 78.

The thickness of the foam adhesive tape 74, ie in the plane in Fig. 3 up or down, is significantly thicker than the thickness of the base wall 70 and the Anputzbereich wall portion 78. It corresponds approximately to the distance at which the downwardly bent plaster end side portion 82 down over the bottom of the wall area plaster portion 78 is and is possibly even slightly larger than this distance formed.

The width of the foam adhesive tape 74, in the drawing plane in Fig. 3 Seen to the left or right, is slightly narrower than the total width of the base wall of the base portion 70. In the present embodiment, the width of the double-sided adhesive foam tape 74 corresponds to about half to two-thirds of the width of the base wall of the base portion 70th

The double-sided adhesive foam adhesive tape 74 may in turn have a certain expansion and compression ability to change the distance between the window or door frame, in particular between the bonded base wall of the base portion 70 and the thermal insulation with plaster layer, in particular the so connected by applying the plaster layer Anputzbereich- Balancing wall portion 78 within certain limits, which ensures a good seal under changing conditions. Due to the thickness and width of the double-sided adhesive foam adhesive tape 74 is a movement between window / door frame on the one hand and thermal insulation and / or plaster layer on the other hand, both in the direction of gap depth and in the direction gap width possible.

On the underside of the base wall of the base region, an additional adhesive strip 76 is provided. This is glued in particular with its upper side on the underside of the base wall of the base region 70. On its underside, this adhesive tape is intended for bonding to the window or door frame. For this purpose, the additional adhesive tape 76 may in particular be provided with a covering means, not shown here, in particular a paper strip which can be removed before mounting the plastering strip 68 and before bonding the additional adhesive tape 76 to the outside of the window or door frame.

Furthermore, the base area 70 and the plastering area 72, in particular the base wall of the base area 70 and the plaster area wall section 78, are interconnected at a position in front of the double-sided adhesive foam adhesive tape 74 by means of a flexible material section 94 which effects a relative movement between the base area 70 and the plastering area 72 allowed. This flexible material portion 94 starts in particular at the front end of the base wall, in particular at an upper side of the front end of the base wall and at the front end of the underside of the plastering area wall portion 78 and is made of the same material, in particular hard plastic, for example PVC, how the base wall and the plastering area 72 were made and thus extruded. Alternatively, the flexible material portion 94 has a softer plastic material than the base wall and the plaster area 72, in particular a thermoplastic elastomer plastic material or TPE, and has been coextruded with the base wall and the plaster area 72.

Optionally, the third plaster bar 68 may have a flexible material portion 94. As in Fig. 3 can be seen, the flexible material portion 94 in the in Fig. 3 illustrated delivery state of the third plaster bar 68 has a curved shape and is designed as a narrow, curved strip of material, which is why the flexible material portion 94 may also be referred to as a loop. If one imagines that the base wall 70 and the wall-wall portion 78 in the installed state of the third plaster bar 68 due to a temperature variation on the building transition away move away and the double-sided adhesive foam tape 74 thereby possibly of the base wall or the Anputzbereich Wall section 78 releases, then extends the flexible material portion 94, wherein the connection thereof between the base wall of the base portion 70 and wall region wall portion 78 is maintained. The flexible material portion 94 thus has a greater expansion reserve than the double-sided adhesive foam adhesive tape 74 and ensures even with increased distances between the base wall of the base portion 70 and wall area plaster portion 78 for sealing therebetween.

On the construction site, first the screed 68 is cut to the appropriate, predetermined by the dimensions of the window or door opening length and is then attached to the building transition between window or door frame and insulation by the grout 68 so in the gap between windows or door frame and insulation inserted or glued in front of the insulation, that the thermal insulation with its front on the back of Wegragschenkels 80 rests. The thermal insulation lies with her gap-side end face on the upper side of the plaster area wall portion 78 at. After optionally before the covering of the additional adhesive tape 76 has been removed, the plaster strip 68 is adhered to the underside of the additional adhesive tape 76 on the front surface of the window or door frame.

After overstretching the window with window frame or the door with door frame with a film which is attached to the protective flap 22, in particular glued, the plastering takes place. In this case, optionally after prior application of a putty behind the reinforcing fabric portion 90, a Armierungsgewebe section 90 and the plastering area up to the plaster removal edge, which is formed by the front end of the Putzendseite 82, reaching out and the Anputzbereich 72 of the Wegragschenkel 80 applied to this plaster removal edge embedding plaster layer. This plaster layer thus covers from the outside, ie in Fig. 3 Seen completely from the right, the plastering area 72 is completely broken off. The strip-shaped protective strip 86 is broken off and removed after the plastering has taken place.

According to the invention have the double-sided adhesive foam tape 8 of the first grout 2, the double-sided adhesive foam tape 32 of the second grout 26 and the double-sided adhesive foam tape 74 and optionally the additional adhesive tape 76 of the third grout 68, which also have foam as a material may, in general, have - in contrast to conventional foam adhesive tapes - a behavior in case of fire, which is at least reduced to the fire protection class B2 "normal flammable" according to DIN standard 4102-1 and in particular in the fire protection class B2 "normal flammable "or in the fire protection class B1" flame retardant "according to DIN standard 4102-1 falls, and that they have a closed-cell foam and a flame retardant.

In order to achieve this fire classification, the base material of the double-sided adhesive foam tape 8, 32, 74 and optionally 76 PVC, polystyrene PS, polypropylene PP or polyolefins, especially polyethylene or polyols, whose behavior in case of fire in the fire protection class B3 "flammable" according to DIN standard 4102-1 falls, and the double-sided adhesive foam tape 8, 32, 74 and optional 76 is also provided with a flame retardant.

The flame retardant may be formed as a halogenated flame retardant, a nitrogen-based flame retardant, an organophosphorus flame retardant, or an inorganic flame retardant.

The flame retardant may be formed as an additive flame retardant, which is introduced as an additive in the base material of the foam adhesive tape, in particular in the polyethylene base material of the foam adhesive tape, in particular in its pores.

The flame retardant may be a halogenated flame retardant selected from the group of TCPP, TDCP, TBBA, TBBPA, chloroparaffins and polyolefins.

The flame retardant may be formed as a non-halogenated flame retardant selected from the group consisting of RDP, BDP, aluminum hydroxide, magnesium hydroxide and trialkyl phosphate. It may in particular be aluminum hydroxide.

The flame retardant may be in the form of phosphoramidates or as a polymer FR, HBCD or DOPO (9,10-dihydro-10-oxa-phosphaphenatrenoxoid).

The closed-cell foam of the double-sided adhesive foam adhesive tape 8, 32, 74 and optionally 76 has a density which is in the range> 20 kg / m ³ and <100 kg / m ³ .

The closed-cell foam of the double-sided adhesive foam adhesive tape 8, 32, 74 and optionally 76 has a material thickness / thickness which is in the range> 2 mm and <10 mm, and a movement absorption capacity of at least 1 mm in material thickness direction.

The closed-cell foam of the double-sided adhesive foam adhesive tape 8, 32, 74 and optionally 76 has a width which is in the range> 6 mm and <20 mm.

The flame retardant can be added during the foaming process of the base material of the foam adhesive tape 8, 32, 74, optionally 76, and thus introduced into the base material and in particular in its pores.

If one imagines the plaster strip 2, 26 and 68 in the installed state at the building transition between window or door frame and insulation, it is, seen in the first plaster molding 2 of the main body from the outside complete covered up to the plaster removal edge on the cleaning end 14 of the plaster layer. In the case of the second plastering strip 26, the displaceable front region / plastering area 40 is completely covered by a plaster layer which reaches up to the plaster removal edge on the plaster end side 56. In the third plaster strip 68, the plastering area 72 is completely covered by a plaster layer up to a plaster removal edge at the end of the plaster end 84.

If one now imagines that the building transition from the outside is exposed to a flame, so this flame reaches only the not covered by the plaster layer area of the respective plaster molding 2, 26 and 68th

This is formed in the first plaster molding 2 of the lower portion of the lying in front of the double-sided adhesive foam tape 8 main body of the plaster strip 2 and from the outside of the double-sided adhesive foam tape. 8

In the second grout, this is the outside of the base wall 30, the outside of the foam adhesive tape 32, and a part of the underside of the grooming area 40.

In the case of the third plastering strip 68, this is the underside of the area of the underside of the plastering area 72 located in front of the double-sided adhesive foam adhesive tape 74 or the flexible material section 94, the flexible material section 94 or the outside of the double-sided adhesive foam adhesive tape 74 outer portion of the base wall of the base portion 70 and the outer portion of the additional adhesive tape 76.

The parts of the plaster molding 2, 26 and 68, which are made of hard plastic, usually have a behavior in case of fire, which corresponds to the fire protection classification B1 "flame retardant" or B2 "normal flammable".

In the case of the first plastering strip 2, this is the main body of the strip with the base wall 4, stand legs 12 and plaster end side 14. In the case of the second plaster strip 26, this is the base wall 30 with guide extension 36 and the displaceable front area / plastering area 40. In the case of the third plaster strip 68, this is the Base wall of the base portion 70 and the plastering area 72 with plastering area wall section 78, with Wegragschenkel 80 and Putzendseite 82nd

In conventional plaster moldings, the adhesive tapes are made of highly flammable polyethylene material, and in the event of fire, a flame can reach them, as can easily be imagined from the above-described installation situations.

Therefore, the behavior in case of fire or the fire classification of the double-sided adhesive foam tape 8 of the first grout 2, the double-sided adhesive foam tape 32 of the second grout 26 and the double-sided adhesive foam tape 74 and optionally the additional adhesive tape 76, the may also have foam, the third grout 68 reduced to the fire protection class B2 "normal flammable" or B1 "flame retardant", as explained above.

In addition, the reinforcing fabric portion 18, 64, 90 of the Anputzleisten 2, 26, 68 may be formed as a glass fiber fabric having a coating and / or finish, and this may also be provided with a flame retardant of the type described here, also for the Reinforcing fabric section 18, 64, 90 of the plaster strips 2, 26, 68 and thus for the entire plaster molding 2, 26, 68, the fire protection classification of fire protection class B2 "normal flammable" or the fire protection class B1 "flame retardant" according to DIN standard 4102- 1 to reach.

Thus, the behavior in case of fire of the entire plastering strip 2, 26, 68 on the fire protection class B2 "normal flammable" or B1 "flame retardant" according to DIN standard 4102-1 is reduced. Thus, an optimal fire protection is also given at the building transition.
