Description

The present invention relates to a plastering strip for placement at a building transition between a first building component designed as a window or door frame and a second building component, in particular thermal insulation and / or a plaster layer, the use of a reinforcing fabric section in a plastering strip for placement at such a building transition and a building transition with such a plastering strip.

Plaster strips are known in numerous embodiments. Particularly typical embodiments are plastering strips that are attached to a window or door frame and enable the plaster layer to be plastered onto the plastering strip instead of up to the window or door frame. As a result, the thermal insulation and / or the plaster layer is decoupled from the window or door frame, which, in the case of large temperature fluctuations that typically occur, ensures that no damage occurs to the end area of the plaster layer, for example through cracks or crumbling, and that the plaster layer is intact at the end remains, as well as that the transition between window or door frame and thermal insulation and / or plaster layer is permanently and reliably sealed.

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

Tests with such plaster strips have shown that if such plaster strips come into contact with a flame from a Bunsen burner when installed, such plaster strips are ignited after some time.

Although the risk of fire promoting is not too high at this position, because the adjacent components, in particular the plaster layer and / or the window or door frame, which is often made of plastic, cannot be ignited, there is, however, a need to reduce the risk of ignition on the plastering strip side lower it as much as possible.

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

This object is achieved by the subject matter of the independent patent claims. Advantageous further developments result from the dependent claims.

According to a first embodiment, a plaster strip according to the invention for placement at a building transition between a first building component designed as a window or door frame and a second building component, in particular thermal insulation and / or a plaster layer, comprises a base body made of plastic; and a double-sided adhesive foam tape, one side of which is connected to the base body by means of an adhesive connection and which is provided with an adhesive layer on the other side and is intended for adhesive connection to the first component of the building.

The plastering area also has a plastering web that protrudes upward and extends along the plastering strip. On the plastered area there is also provided an upwardly protruding reinforcing fabric section to be embedded in the plaster. The reinforcement fabric section to be embedded in the plaster can be attached to the plaster web. This reinforcement fabric section is designed as a glass fiber fabric, the coating and / or finish of which has a flame retardant.

According to a second embodiment variant, a plaster strip according to the invention for placement at 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 area; a plastering area intended for plastering into the plaster layer and / or for a permanent connection with the thermal insulation; a double-sided adhesive foam tape, one side of which is adhesively bonded to the base area and another side is adhesively bonded to the plastered area; and an additional adhesive tape, in particular made of foam, which is connected to the base area on one side by means of an adhesive connection and which is equipped with an adhesive layer on the other side and is intended for connection to the first component of the building.

The plastering area also has a plastering web that protrudes upward and extends along the plastering strip. On the plastered area there is also provided an upwardly protruding reinforcing fabric section to be embedded in the plaster. The reinforcement fabric section to be embedded in the plaster can be attached to the plaster web. This reinforcement fabric section is designed as a glass fiber fabric, the coating and / or finish of which has a flame retardant.

The present patent application is directed to the independent subject matter of the invention, in which the reinforcing fabric section is designed as a glass fiber fabric, the coating and / or finish of which has a flame retardant.

According to one finding of the inventors, the reinforcing fabric section of conventional plastering strips is often provided with a coating that is inherently easily combustible. So far, no attention has been paid to this, as only the basic material of the plastering strip and its flammability were in focus. Therefore, the inventor has found that by providing the coating and / or the finishing of the reinforcement fabric section of the plastering strip, which is designed as a glass fiber fabric, with a flame retardant, the behavior of the reinforcement fabric section in the event of fire changes to fire protection class B2 "normally inflammable" or to fire protection class B1 " flame retardant ”can be reduced, which has a corresponding effect on the classification of the plaster strip as a whole in precisely 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 a fire with a different fire effect can also arise during the installation phase. Because, according to the invention, the behavior of the reinforcement fabric section in the event of fire is reduced to at least fire protection class B2 "normally flammable" according to DIN standard 4102-1 and by reducing the risk of inflammation of the plastering strip as a whole, a fire can also develop or spread can be effectively counteracted during the installation phase, in which the reinforcement fabric section is partially accessible to a flame over a large area.

The inventor of the present patent application has also determined that the main material, i.e. the material of the base body of the plastering strip, is not decisive for the risk of inflammation of a plastering strip in the installed state, because this is largely covered by the plaster layer, but rather the intermediate layer between the plastering strip and The window or door frame plays a crucial role here, as it is arranged in the gap between the window or door frame and the thermal insulation and / or plaster layer and is accessible from the outside of the building and therefore exposed to possible fire exposure in the event of a fire.

According to a further finding, the main material of the plastering strip is usually made of flame-retardant material, in particular from hard PVC, but that part of the plastering strip that is accessible from the outside and is exposed to a flame and thus a fire load in the event of fire, namely the adhesive tape with which the plastering strip is glued to the window or door frame, made of a material that is easily combustible.

According to a further aspect of the present invention, the behavior of the foam adhesive tape in the event of fire is at least “normally flammable” according to fire protection class B2 DIN standard 4102-1 reduced. As a relevant state of DIN standard 4102-1 the May 1998 issue will be viewed.

This ensures that the properties and advantages of the plaster strip are retained unchanged and that, in particular, the simple gluing of the plaster strip to the first building component and the movement absorption of the foam adhesive tape are retained.

Because the behavior of the foam adhesive tape in the event of fire is at least to fire protection class B2 "normally flammable" according to the DIN standard 4102-1 can be reduced, the risk of inflammation of the foam adhesive tape is significantly reduced. This also reduces the overall risk of the plastering strip catching fire.

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 a fire with a different fire effect can also arise during the installation phase. As a result of the fact that the behavior of the entire foam adhesive tape, and not only partially against lateral exposure to flames, in the event of fire is reduced to at least fire protection class B2 "normally flammable" according to DIN standard 4102-1 and by reducing the risk of inflammation of the plastering strip as a whole the development or spread of a fire can also be effectively counteracted during the installation phase.

In the first variant, the risk of inflammation of the plastering strip is reduced to a minimum, because the components of the plastering strip that are accessible from the outside after installation of the same at the building transition and plastering has taken place and can be reached by a flame in the event of fire, namely the foam adhesive tape and the underside of the base body, both each have a base material whose behavior in the event of a fire falls into at least fire protection class B2 "normally flammable", in the case of the base body usually even falls into fire protection class B1 "flame retardant" and because the double-sided adhesive foam tape also has a flame retardant .

In the second variant, too, the risk of inflammation of the plastering strip can be reduced to a minimum if the components of the plastering strip that are accessible from the outside after they have been installed at the building transition and plastering has taken place and can be reached by a flame in the event of a fire, namely those to the outside facing sides of the adhesive tape, the base area and the foam adhesive tape and, if applicable, the underside of the plastered area, all each have a base material whose behavior in the event of fire is at least in fire protection class B2 "normally flammable", in the case of the base body even mostly in fire protection class B1 "hardly inflammable" “And because the double-sided foam tape also contains a flame retardant.

With the plastering strips according to the invention according to the first and second embodiment variants, the risk of inflammation is thus significantly reduced compared to conventional plastering strips, without any deterioration in the other properties of the plastering strips.

At this point, it should be noted that instead of the fire protection classes B1 "hardly inflammable" and B2 "normally inflammable" of DIN standard 4102-1, the corresponding fire behavior classes from European standard EN13501-1 can be used as a reference.

• B; C-s1, d0 B1
• A2; B; C-s2, d0
• A2; B; C-s3, d0
• A2; B; C-s1, d1
• A2; B; C-s1, d2

Fire protection class B1 according to DIN standard 4102-1 corresponds to the following classes of EN standard 13501-1:

• B; C-s1, d0 B1
• A2; B; C-s2, d0
• A2; B; C-s3, d0
• A2; B; C-s1, d1
• A2; B; C-s1, d2

• E-d2

The fire protection class B2 "normally inflammable" of the DIN standard 4102-1 corresponds to the following classes of the EN standard 13501-1:

• D-s1, d0
• D-s2, d0
• D-s3, d0
• D-s1, d2
• D-s2, d2
• D-s3, d2
• E.
• E-d2

The fire protection class B1 "hardly inflammable" means that the flammability must remain limited to the extent specified in DIN 4102-1 in the event of edge or surface exposure with a small flame.

Fire protection class B2 "normally flammable" means that the fire will extinguish itself after the source of the fire has been removed.

With regard to DIN standard 4102-1, the plastering strip according to the invention is to be regarded as external wall cladding in the sense of 6.1.1 b). In a test in which the flames striking from a wall opening are represented as a model, and the resulting exposure, the spread of the fire must not extend significantly outside the primary fire area.

According to 6.1.2.1 of DIN standard 4102-1, plastering strips according to the invention, which are to be regarded as building materials, with the exception of floor coverings, meet the requirements for classification in building material class B1 if they pass the fire shaft test and meet the requirements for building material class B2.

1. a) with edge flaming according to 6.2.5.2 and
2. b) if applicable, in the case of surface exposure to 6.2.5.3

the flame tip reaches the measuring mark before the end of the 20th second.

With regard to the samples and the pretreatment, see 6.2.3, with regard to the test equipment to 6.2.4, with regard to the test to 6.2.5, and with regard to the test for burning debris (dripping) to 6.2.6 and with regard to the test certificate to 6.2.7 refer to DIN standard 4102-1.

The foam adhesive tape is not a single-sided adhesive tape, but a double-sided adhesive foam adhesive tape, which is equipped with an adhesive layer on each of its opposite sides.

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

In the installed state, the plastering strip, first variant, is adhesively connected to this component of the building by means of this adhesive layer on the other side of the double-sided adhesive foam tape.

In the plastering strip, second variant, the double-sided adhesive foam tape is adhesively connected to the base area by means of the adhesive layer on one side and to the plastering area by means of the adhesive layer on the other side.

According to the first and second variant embodiments, the foam adhesive tape according to the invention usually has a closed-cell foam.

This represents a significant difference to conventional one-sided adhesive PUR sealing tapes, which usually have an open-cell foam because they are impregnated for driving rain and such an impregnation is only possible with open-cell, but not with closed-cell foam materials.

A conventional, one-sided adhesive PUR sealing tape does not bond and thus does not create a connection to the building component to which it is attached, in the diction of independent claim 1, no bond and therefore no connection to the first building component.

Because the foam adhesive tape in the first and second variant of the plastering strip according to the invention has a closed-cell foam, it is inherently impervious to moisture or water, for example against rain or driving rain or - in the case of a horizontal installation of the plastering strip - against standing Water.

Moisture or water cannot get into the interior of 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, water- and moisture-tight. No water or moisture is absorbed, as is the case with conventional, single-sided, open-cell PUR sealing tapes.

Because the foam of the double-sided adhesive foam tape is closed-cell, there is only a very limited possibility of expansion and movement absorption, which is usually in the range between 1 mm and 2 mm, which is sufficient for most applications and which is an additional demarcation from conventional ones represents single-sided adhesive and open-cell PUR sealing tapes.

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

According to a further embodiment of the first variant of the plastering strip according to the invention, the base area and the plastering area are designed in one piece. One side of the double-sided adhesive foam tape is adhesively connected to the base area by means of an adhesive bond.

According to a further embodiment of the first variant of the plastering strip according to the invention, the base area and the plastering area are designed separately from one another, that - if necessary after severing a strip-shaped protective flap - a relative movement between the base area and plastered area is made possible by means of a guide connection.

According to one embodiment of the first and second variant of the plastering strip according to the invention, the base area and the plastering area are connected to one another 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 variant of the plaster strip according to the invention, the base area is designed as a base wall. The plastering area can have a plastering area wall section which is arranged parallel to the base wall. The additional adhesive tape can be attached to an underside of the base wall by means of an adhesive connection. The double-sided adhesive foam tape can be connected with one side by means of an adhesive connection to the top of the base wall and with another side by means of an adhesive connection to the underside of the plastering area wall section. The flexible material section can connect an end section of the base wall to an end section of the plastering area wall section at a position in front of the foam adhesive tape, and allow a relative movement between the base area and plastering area.

According to a further embodiment of the second embodiment variant of the plastering strip according to the invention, the plastering area furthermore has a plastering area end section, in particular an inclined downwardly directed plastering area end section, on the front of its plastering area wall section. When viewed from the front, the plastering area end section can cover the flexible material section.

According to a further embodiment of the second variant of the plaster strip according to the invention, the additional adhesive tape also has foam, and the behavior of the additional adhesive tape made of foam in the event of fire is also reduced to at least the fire protection class B2 "normally inflammable" according to DIN standard 4102-1. All the advantages and embodiments that have been described here with reference to the double-sided adhesive foam adhesive tape apply to the additional adhesive tape. These are not explained again to avoid repetition.

The following embodiments relate to both the first and the second variant of the plastering strip according to the invention.

The plastering strip can furthermore have a strip-shaped protective flap 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 tape is designed so that the walls between the individual cells are completely closed.

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

According to a further embodiment of the present invention, this density range for the foam material of the double-sided adhesive foam tape relates to the installed state of the plaster strip.

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

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, the density of which falls within the claimed range and a material thickness that falls within the claimed range, represents an optimal compromise between good fire behavior and good movement absorption.

The inventor has also found that the thicker and denser the foam adhesive tape, the better the fire behavior, and that, on the other hand, when using a foam adhesive tape in a plaster strip, it is not advisable to use a foam adhesive tape that is too dense Foam material should be selected, since the absorption of movement is then too low, because a foam adhesive tape with dense foam material only has insufficient absorption of movement.

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

The inventor has also found that a minimum thickness of 2 mm and a minimum width of 6 mm are advantageous for the double-sided adhesive foam tape. Towards the top, the thickness of the double-sided adhesive foam tape should not exceed 10 mm and the width of the same 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 tape is designed as a non-expanding foam.

Expanding foam adhesive tapes are usually held in a compressed state in the delivery state by means of a locking means. This means of locking is released when the plastering strip is installed. The foam adhesive tape then expands and then has a thickness / material strength that is usually a multiple of the thickness / material strength in the delivery state.

In the case of the double-sided adhesive foam tape according to the invention, however, the thickness / material thickness in the delivery state essentially corresponds to the thickness / material thickness in the installed state. A difference usually only arises from the absorption of movement, for example by reducing the distance between the first and second building components.

The behavior of the double-sided adhesive foam tape in the event of fire can be attributed to fire protection class B1 "hardly inflammable" according to the DIN standard 4102-1 be reduced.

The flame retardant of the foam adhesive tape can change the behavior of the foam adhesive tape in the event of a fire to fire protection class B2 “normally flammable” or to fire protection class B1 “hardly inflammable” according to the DIN standard 4102-1 to reduce.

If flame retardant (s) are mentioned below, it is to be understood that these are both the flame retardant (s) with which the double-sided adhesive foam tape can optionally be provided, and the flame retardant (s), with which the coating and / or the finish of the reinforcement fabric section designed as a glass fiber fabric is provided.

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

The flame retardant can be designed as an additive flame retardant which is incorporated as an additive into the base material of the coating and / or finish of the reinforcing fabric section.

The flame retardant can be designed as a halogenated flame retardant which is selected from the group of TCPP, TDCP, TBBA, TBBPA, chlorinated paraffins and polyolefins.

The flame retardant can be designed as a non-halogenated flame retardant which is selected from the group of RDP, BDP, aluminum hydroxide, magnesium hydroxide and trialkylphosphates.

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

The invention also relates to the use of a reinforcement fabric section in a plastering strip according to the first variant for placement at 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 , which has a base body made of plastic, to reduce the behavior of the reinforcement fabric section in the event of fire to fire protection class B2 "normally flammable" according to the DIN standard 4102-1: 1998 or to fire protection class B1 “hardly inflammable according to DIN standard 4102-1: 1998 ; The double-sided adhesive foam tape is connected to the base body on one side by means of an adhesive connection and is equipped with an adhesive layer on the other side and is intended for adhesive connection to the first component of the building; wherein the reinforcement fabric section is designed as a glass fiber fabric, the coating and / or finish of which has a flame retardant.

The first plastering strip 2 , the second plastering strip 26th , and the third plastering strip 68 are described below as representative of any plastering strips, they are characterized by an over the entire length of a constant profile cross-section. The base area 4th , the plastering area 10 and the strip-shaped protective flap 22nd the first plastering strip 2 , the base area 28 (without foam tape 32 ), the sliding front area 40 and the strip-shaped protective flap 60 the second plastering strip 26th , as well as the base area 70 (without foam tape 74 and 76 ), the plastering area 72 and the strip-shaped protective flap 86 the third plastering strip 68 are inexpensive to manufacture by extrusion and form extrusion parts.

The 1 , 2 and 3 show the plastering strips 2 , 26th and 68 in the delivery condition, with the strip-shaped protective flap 22nd , 60 or. 86 has not yet been severed.

In the 1 first plastering strip shown as an example 2 includes a base area 4th and a plastering area 10 with a reinforcement fabric section 18th and a strip-shaped protective flap 22nd .

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

The strip-shaped protective flap 22nd is by means of a break-off material bridge 24 with a cleaning end side 14th of the plastered area 10 connected. The strip-shaped protective flap 22nd still has a spacer bar that is used when the plastering strip is installed 2 can rest on the outside of a first building component.

The base area 4th , the plastering area 10 and the strip-shaped protective flap 22nd have been produced together by extrusion.

The base area 4th is present by an in 1 horizontally running base wall 6th and a double-sided adhesive foam tape attached to it 8th formed, which is 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 from the outside of the Wegrag leg 12 , from the cleaning end side facing away from the window or door frame 14th and from the reinforcement fabric section 18th educated.

The first plaster strip is on the underside 2 a stepped course, the underside of the cleaning end side 14th based on the installation situation, is closer to the window / door frame than the underside of the base wall 6th .

The reinforcement mesh section 18th is present with the way leg 12 by means of a welded connection 20th connected.

The cleaning end side facing away from the window or door frame 14th and the surface of the path leg facing from the thermal insulation in the direction of the opposite window or door frame side 12 are with a channel profile 16 to improve the adhesion of the plaster.

First of all, the plastering strip is installed on site 2 cut to the appropriate length given by the dimensions of the window or door opening and then attached to the transition between window / door frame and thermal insulation by the plastering strip 2 with their base area 4th is inserted into the gap between the window or door frame and the thermal insulation, so that the plastering strip 2 with the top of their base wall 6th rests against the gap-side face of the thermal insulation, with the back of its Wegrag leg 12 on the outside of the thermal insulation and with the double-sided adhesive foam tape 8th is glued to the surface of the window or door frame.

After covering the window with the window frame or the door with the door frame with a film, which is attached to the strip-shaped protective flap 22nd is attached, especially glued, plastering takes place. In this case, if necessary after prior application of a filler behind the reinforcement fabric section 18th one the reinforcement fabric section 18th and the plastering area 10 Plaster layer embedding up to a plaster removal edge applied, which essentially goes through the end of the plaster end side 14th is formed to which the strip-shaped protective flap 22nd connects. The strip-shaped protective flap 22nd is broken off and removed after plastering.

The double-sided adhesive foam tape 8th may have some expansion and compression capability to accommodate changes in spacing between the underside of the base wall 6th and to level the surface of the window or door frame within certain limits, which ensures a good seal in changing conditions.

In the 2 second plastering strip shown as an example 26th has like the first plastering strip 2 over a base area 28 , which can be fastened with a section on a first building component, in particular a window or door frame, via a plastered area 40 , the present as a movable front area 40 is formed on which a reinforcement fabric section 64 is attached and together with the reinforcement fabric section 64 is intended for embedding in a layer of plaster, as well as a strip-shaped protective flap 26th .

With the strip-shaped protective flap 60 the adhesive layer applied to the outside can now be seen, it is over a break-off material bridge 62 both with the base area 28 as well as with the plastering area 40 connected, otherwise it agrees with the strip-shaped protective flap 22nd out 1 and will not be explained again in the following.

Unlike the one-piece first plastering strip 2 is the second plastering strip 26th now designed in two parts, with a base area 28 and a sliding plastering area 40 .

The base area 28 includes a base wall 30th with a foam adhesive tape attached to the underside 32 , which is described in more detail below and the one with its underside in the mounted state of the plastering strip 26th rests sealingly on the window or door frame and is glued to it.

At the far right end of the base wall 38 For example, a protective lip, not shown here, can extend downward, which lip can be formed from a softer, flexible plastic material and can thus have a certain flexibility. Such a flexible protective lip can be in the installed state of the second plaster strip 26th Apply to the surface of the window or door frame in a position outside of the double-sided adhesive foam tape 32 and thus reliably prevents moisture from getting to the double-sided adhesive foam tape 32 can arrive. The protective lip can in particular together with the base wall 30th and the guide extension explained in more detail below 36 , with the plastering area 40 and the strip-shaped protective flap 60 be coextruded.

A guide extension 36 protrudes upward from the base wall 30th away and is formed integrally with this. This guide extension 36 comprises a widened end head arranged at the top 38 , an underlying extension wall area of smaller wall thickness and a connection to the base wall 30th forming extension wall area of further reduced wall thickness.

The movable plastering area 40 is subdivided into a path leg arranged at the top 36 , a recording room behind it 42 with internal thermal insulation system side 48 and outer plaster side 54 , with the leg leg 46 an inner plaster side 50 and an outer plaster side 54 has, and in one at the lower outer end of the receiving space 42 attached and outwardly running cleaning end side 56 .

The recording room 42 is sized so that the front end of the end head 38 when completely in the recording room 42 located guide process 36 and accordingly when the rear end face of the side walls of the receiving space is abutted 42 at the front of the base wall 30th at a short distance from the upper wall of the recording room 42 is positioned. At the lower end of the inside of the recording room 42 set opposing guide projections 44 and extend so far inside, based on the symmetry axis of the receiving space 42 that they are the guide process 36 pick up and lead in between. In the position of the guide extension shown 36 take hold of the leading edge 44 in the lowest area of the guide process 36 with reduced wall thickness and keep this guide extension 36 and thus the entire base area 36 regarding the movable plastered area 40 in the minimum shift position. The leadership lead 44 can be made from a plastering area that can be displaced in relation to the material 40 made of softer plastic material.

If one imagines that the break-off material bridge or the break-off material bridge 62 of the base area 28 and the movable plastering area 40 to the strip-shaped protective flap 60 can be cut through, the plastered area 40 compared to the base area 28 be moved, up to a maximum displacement position at which the guide projections 44 to the end head 38 attacks. This allows movements between the thermal insulation / plaster layer and the window / door frame to be compensated in a particularly advantageous manner.

From a central area of the upper wall of the recording room 42 the upper leg extends 46 up. The inside plaster side 50 and the outer plaster side 52 of the path leg 46 , the outer plaster side 54 the outer wall of the recording room 42 and the cleaning end side 56 are with grooves 58 provided in order to enlarge the surface to which the plaster adheres and thus create a better connection with the plaster. This gutter profiling 58 can, as in 2 can also be seen on the front wall of the recording room 42 extend.

On the outer plaster side 52 of the path leg 46 is an in 2 reinforcing fabric section extending forward 64 attached, by means of a welded connection 66 .

When installing the second plastering strip 26th there does not have to be a gap between the thermal insulation and the window / door frame.

First of all, the plastering strip is installed on the construction site 26th cut to the appropriate length given by the dimensions of the window or door opening and then attached to the transition between window / door frame and thermal insulation by using the thermal insulation system side 48 applied to the thermal insulation and with the double-sided adhesive foam tape 32 applied to the window / door frame and glued. Then the protective film is stretched over the window or door frame and on the adhesive layer of the strip-shaped protective flap 60 fixed. Then the plastered area is plastered 40 , if necessary after previously applying filler behind the reinforcement fabric section 64 . This filler can in particular form the space between the outside of the thermal insulation and the reinforcement fabric section 64 to complete. When cleaning, the plaster layer extends either over the entire, with channel profiling 58 provided area of the plastered area 40 or, if filler has been applied, over the outer plaster sides 52 , 54 and over the cleaning end side 56 up to the cleaning end edge, which passes through the end of the cleaning end side 56 is defined.

After the plastering has taken place, the strip-shaped protective flap 60 removed by the break-off material bridges 62 severed, for example pulled off by hand, optionally with cutting the ends.

By cutting through the break-off material bridge 62 over the strip-shaped protective flap 60 before that the base area 28 and the movable plastering area 40 held together is the sliding plastered area 40 now from the base area 28 decoupled and can be separated by the construction with a guide extension 36 , End head 38 , and recording room 42 with leading edge 44 opposite the base wall 30th move, and thus compensate for movements between the thermal insulation and plaster layer as well as window / door frames.

With the second plaster strip 26th it is a two-part plastering strip, described as an example, in which two areas 28 and 40 can be moved against each other in order to compensate for movements between the thermal insulation / plaster layer and the window / door frame.

Other two-part plaster strips are also covered by the invention, in particular also two-part plaster strips that are at least partially inserted into a gap between the thermal insulation and the window / door frame.

This will be plastering strips, where the base area 28 and the plastering area 40 are connected to one another, for example by means of a flexible material area, a so-called loop, are viewed as one-piece plaster strips. Plastering strips where the base area 28 and the plastering area 40 are not connected to each other, however, are viewed as two-part plaster strips.

In the 3 third plastering strip shown as an example 68 includes a base area 70 , a plastering area 78 with a reinforcement fabric section 90 and a strip-shaped protective flap 86 .

The base area 70 is designed in the form of a base wall. The plastering area 72 comprises a plastering area wall section 78 that is parallel to the base wall of the base region 70 arranged and about the same width as this, a building outside Putzendeiten section 82 on the inside of the plastered area wall section 78 attaches and which is kinked downwards, so in the direction of the window or door frame, and one of the plastering area wall section protruding upward leg leg 80 .

The base area 70 and the plastering area 78 are formed separately from each other. It is therefore a two-part plaster strip in which the base area 70 and the plastering area 72 can be shifted against each other in order to compensate for movements between the thermal insulation / plaster layer and window / door frame.

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

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

The plastering area 72 includes the left of the path leg 80 located fixing side and the one to the right of the Wegrag leg 80 located plaster side.

The specification page is in particular used by the in 3 left back of the Wegrag leg 80 and from the in 3 upper side of the left of the path leg 80 located section of the plastering area Wall section 78 educated. One can easily imagine that thermal insulation is applied to the corner bracket formed in this way.

The plaster side is taken from the in 3 right outside of the Wegrag leg 80 , from the plaster end face facing away from the window or door frame 84 , including the one on the right, i.e. outside the Wegrag leg 80 located section of the plastering area wall section 78 educated.

Like in the 1 , so is the third plaster strip 68 again a reinforcement fabric section 90 by means of a welded connection 92 on the leg of the path 80 especially attached to the outside. The direction in which the reinforcement fabric section extends 90 lies parallel to the extension direction of the Wegrag leg 80 .

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

The base wall of the base area 70 and the plastering area wall section 78 of the plastered area 72 are by means of a double-sided adhesive foam tape 74 connected with each other. This is in particular with its lower adhesive side with the upper side of the base wall of the base area 70 and with its top to the bottom of the plastering area wall section 78 glued.

The thickness of the foam tape 74 , i.e. in the drawing plane in 3 seen up or down, is clearly thicker than the thickness of the base wall 70 or the plastered area wall section 78 . It corresponds roughly to the distance with which the downwardly bent cleaning end section 82 down over the underside of the plaster area wall section 78 stands and is possibly even formed somewhat larger than this distance.

The width of the foam tape 74 , in the drawing plane in 3 seen to the left or right, is dimensioned somewhat narrower than the total width of the base wall of the base area 70 . In the present exemplary embodiment, the width of the double-sided adhesive foam adhesive tape corresponds 74 about one-half to two-thirds the width of the base wall of the base region 70 .

The double-sided adhesive foam tape 74 can in turn have a certain ability to expand and compress to allow for changes in the distance between the window or door frame, in particular between the base wall of the base area that is glued to it 70 and the thermal insulation with plaster layer, in particular the plaster area wall section connected to it by applying the plaster layer 78 to compensate within certain limits, which ensures a good seal in changing conditions. Due to the thickness and width of the double-sided adhesive foam tape 74 It is possible to record movement between the window / door frame on the one hand and the thermal insulation and / or plaster layer on the other, both in the direction of the gap depth and in the direction of the gap width.

On the underside of the base wall of the base area is an additional adhesive strip 76 intended. This is in particular with its upper side on the lower side of the base wall of the base area 70 glued. On its underside, this adhesive tape is intended to be glued to the window or door frame. The additional tape can be used for this 76 in particular be provided with a covering means not shown here, in particular a paper strip, which is applied before the plastering strip is installed 68 and before gluing the additional adhesive tape 76 can be removed on the outside of the window or door frame.

Furthermore are the basic area 70 and the plastering area 72 , especially the base wall of the base area 70 and the plastering area wall section 78 at a position in front of the double-sided adhesive foam tape 74 by means of a flexible section of material 94 connected to each other, which has a relative movement between base area 70 and plastering area 72 allowed. This flexible section of material 94 sets in particular on the front end of the base wall, in particular on an upper side of the front end of the base wall and on the front end of the underside of the plastering area wall section 78 and is made of the same material, especially hard plastic, for example PVC, as the base wall and the plastered area 72 produced and thus extruded. Alternatively, the flexible material section 94 a softer plastic material than the base wall and plaster area 72 on, in particular a thermoplastic elastomer plastic material or TPE and is with the base wall and the plastered area 72 been coextruded.

The third plastering strip can be used as an option 68 via a flexible section of material 94 feature. As in 3 can be seen, the flexible material section 94 in the in 3 the delivery status of the third plaster strip shown 68 has a curved shape and is designed as a narrow, curved strip of material, which is why the flexible material section 94 can also be referred to as a loop. If you imagine that the base wall 70 and the plastering area wall section 78 in the installed state of the third plaster strip 68 due to a temperature fluctuation at the building junction move away from each other and the double-sided adhesive foam tape 74 possibly from the base wall or the plastered area wall section 78 releases, then the flexible section of material stretches 94 , the connection of the same between the base wall of the base region 70 and plastering area wall section 78 preserved. The flexible material section 94 thus has a greater stretch reserve than the double-sided adhesive foam tape 74 and also takes care of the increased spacing between the base wall of the base area 70 and plastering area wall section 78 for a seal in between.

First of all, the plastering strip is installed on the construction site 68 cut to the appropriate length given by the dimensions of the window or door opening and is then attached to the building transition between window or door frame and thermal insulation by the plastering strip 68 so inserted into the gap between the window or door frame and the thermal insulation or glued in front of the thermal insulation that the thermal insulation is with its front on the back of the path leg 80 is applied. In this case, the thermal insulation lies with its gap-side end face on the top of the plastered area wall section 78 at. After, if necessary, the covering means of the additional adhesive tape beforehand 76 has been removed, the plaster strip becomes 68 with the bottom of the additional tape 76 glued to the front surface of the window or door frame.

After covering the window with the window frame or the door with the door frame with a film attached to the protective flap 22nd is attached, especially glued, plastering takes place. In this case, if necessary after prior application of a filler behind the reinforcement fabric section 90 , one the reinforcement fabric section 90 and the plastering area up to the plastering edge that passes through the front end of the plastering end side 82 is formed, sufficient and the plastered area 72 from the leg of the path 80 Plaster layer embedding up to this plaster removal edge is applied. This layer of plaster thus covers from the outside, i.e. in 3 Seen from the right, the plastered area is completely visible 72 . The strip-shaped protective flap 86 is broken off and removed after plastering.

The double-sided adhesive foam tape 8th the first plastering strip 2 , the double-sided adhesive foam tape 32 the second plastering strip 26th and the double-sided adhesive foam tape 74 and optionally the additional adhesive tape 76 the third plastering strip 68 , which can also have foam as a material, can have in common that - in contrast to conventional foam adhesive tapes - they behave in the event of fire that at least corresponds to fire protection class B2 "normally flammable" according to the DIN standard 4102-1 is reduced and in particular to fire protection class B2 “normally flammable” or to fire protection class B1 “hardly inflammable” according to the DIN standard 4102-1 falls, and that they have a closed cell foam and a flame retardant.

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

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

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

The flame retardant can be designed as a halogenated flame retardant which is selected from the group of TCPP, TDCP, TBBA, TBBPA, chlorinated paraffins and polyolefins.

The flame retardant can be designed as a non-halogenated flame retardant which is selected from the group of RDP, BDP, aluminum hydroxide, magnesium hydroxide and trialkylphosphates. In particular, it can be aluminum hydroxide.

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

The closed-cell foam of the double-sided adhesive foam tape 8th , 32 , 74 and optional 76 can have a density in the range> 20 kg / m ³ and <100 kg / m ³ .

The closed-cell foam of the double-sided adhesive foam tape 8th , 32 , 74 and optional 76 can have a material thickness in the range> 2 mm and <10 mm, and a movement absorption capacity of at least 1 mm in the direction of the material thickness.

The closed-cell foam of the double-sided adhesive foam tape 8th , 32 , 74 and optional 76 can have a width in the range> 6 mm and <20 mm.

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

If you look at the plastering strip 2 , 26th and 68 in the installed state at the building transition between the window or door frame and thermal insulation, so is the first plaster strip 2 the base body viewed from the outside completely up to the plaster removal edge on the plaster end side 14th covered by the plaster layer. With the second plaster strip 26th is the movable front area / plastering area 40 completely from a plaster layer that extends to the plaster removal edge on the plaster end side 56 sufficient, covered. On the third plaster strip 68 is the plastering area 72 up to a plaster removal edge at the end of the plaster end side 84 completely covered by a layer of plaster.

If you now imagine that the building transition is exposed to a flame from the outside, this flame only reaches the area of the respective plaster strip that is not covered by the plaster layer 2 , 26th and 68 .

This will be the first plastering strip 2 formed by the lower area of the double-sided adhesive foam tape 8th lying body of the plastering strip 2 as well as from the outside of the double-sided adhesive foam tape 8th .

For the second plaster strip, this is the outside of the base wall 30th who have favourited the outside of the foam tape 32 , and part of the underside of the plastered area 40 .

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

The parts of the plastering strip 2 , 26th and 68 that are made of hard plastic usually have a behavior in the event of fire, which corresponds to the fire protection classification B1 "hardly inflammable" or B2 "normally inflammable".

At the first plastering strip 2 this is the main body of the bar with base wall 4th , Throw-away leg 12 and cleaning end side 14th . With the second plaster strip 26th is this the base wall 30th with guide process 36 and the sliding front area / plastering area 40 . On the third plaster strip 68 this is the base wall of the base area 70 and the plastering area 72 with plastered area wall section 78 , with detachable leg 80 and with cleaning end 82 .

In conventional plastering strips, the adhesive tapes are made of easily inflammable polyethylene material, and in the event of a fire, a flame can reach them, as can be easily imagined from the installation situations explained above.

Therefore, the behavior in the event of fire or the fire protection classification of the double-sided adhesive foam tape 8th the first plastering strip 2 , the double-sided adhesive foam tape 32 the second plastering strip 26th and the double-sided adhesive foam tape 74 and optionally the additional adhesive tape 76 , which can also have foam, the third plaster strip 68 be reduced to fire protection class B2 “normally flammable” or B1 “hardly flammable”, as explained above.

The reinforcement mesh section 18th , 64 , 90 the plastering strips 2 , 26th , 68 is designed as a glass fiber fabric, which has a coating and / or finish, and this can also be provided with a flame retardant of the type described here in order for the reinforcement fabric section 18th , 64 , 90 the plastering strips 2 , 26th , 68 and thus for the entire plastering strip 2 , 26th , 68 to achieve the fire protection classification of fire protection class B2 “normally flammable” or fire protection class B1 “hardly inflammable” according to DIN standard 4102-1.

This ensures the behavior of the entire plastering strip in the event of fire 2 , 26th , 68 reduced to fire protection class B2 “normally flammable” or B1 “hardly flammable” according to DIN standard 4102-1. This means that there is also optimal fire protection at the building transition.
