Description

The invention relates to a plaster molding for placement on a building corner and a building corner with a plaster strip arranged thereon.

In the construction of buildings usually proceeded so that window bars and door frames, which are fixed to the building connected fixed window or door frame, are inserted into corresponding wall openings of the shell and fastened there. In a later phase, the shell is plastered outside and inside. Here, especially on the outside of the building, the connection of the plaster to the window sash or door frame is a critical point, because the plaster abuts the front of the material of the window sash or door sill and there is no perfect bond. Since the plaster shrinks slightly during drying, since windows and door sills are exposed to vibrations, for example, by violent slamming the windows or doors, and since such building corners are also exposed to high temperature fluctuations, there is a risk that a crack or gap between the plaster and forms the window floor or door sill. Here then moisture can penetrate, which damages the window stock, the door frame or the plaster in the long run, for example leads to crumbling of the plaster.

Therefore, frequently plaster strips are provided at the transition between window or door frame to the plaster, which should decouple the window or door frame from the plaster and at the same time provide a seal between them. Furthermore, a protective film is often attached to the plaster molding during assembly and plastering, which is stretched over the window or door frame and should protect it from damage and dirt. Cleaning strips that allow the sticking of such a protective film, as has been shown, only with a relatively high output producible. In addition, the removal of the protective film together with a correspondingly with to be removed portion of the plastering line often causes problems, especially at cold temperatures that occur regularly on the site, especially in winter. Sometimes the removal is possible only with great effort, in other cases, the corresponding section of the plaster strip breaks off too early. Another problem arises from the risk of injury that occurs during or after removal of the protective film together with the corresponding section of the plaster molding.

It is therefore an object of the present invention to provide a plasterboard, which allows a simple, clean and injury-free removal of the protective tab at all temperatures occurring on a construction site. Such a plaster strip should be able to be produced reliably and with only a small amount of rejects.

This object is achieved by the subject matter of the independent claim, advantageous developments emerge from the dependent claims.

The invention relates to a plaster molding for placement at a transition between a component of a building, in particular a window or door frame or a sill, a beam, a metal connection or a Lisene, and a thermal insulation and / or a plaster layer. This plaster strip comprises a base body with a section intended for embedding in a plaster layer and a strip-shaped protective strip on which a protective film for the building component can be fastened. The strip-shaped protective tab is connected to the base body via a soft connecting bridge, which has a softer plastic material than the material of the base body.

DE 20 2009 013 120 U1 shows a one-piece plaster molding for placement at a junction between a first component of a building, in particular a window or door frame, a window sill, a beam, a metal connection or a Lisene, and a second component of a building, in particular a thermal insulation or a plaster layer, comprising a base portion provided on its rear side with an adhesive strip extending along the plaster molding strip for adhesively bonding the plaster molding strip to the building component; and an at least partially lying next to the base region Anputzbereich which is intended for plastering in a plaster layer, wherein the base region is laterally connected on one side via a flexible connector with the Anputzbereich, wherein the flexible connector is formed such that it is a displacement of the Anputzbereichs Partially moved in a direction away from the first building component and thus ensures that the base area remains stationary and the adhesive strip continues to adhere to the first building component. Furthermore, the DE 20 2009 013 120 U1 a break-off strip for attaching a protective film, which is connected via a material bridge of reduced thickness with the plastering area.

The connecting bridge, which has a softer plastic material than the material of the base body, is also referred to below as a "soft connection bridge".

The material of the connecting bridge is chosen so that it gives the connecting bridge on the one hand enough rigidity, so that the strip-shaped protective flap is held during assembly and plastering against the base body of the plaster strip in position, in particular rests against the building component, and that the strip-shaped Protective tab can be separated easily and independently of the prevailing temperatures at the same time.

A risk of dipping, which results from the fact that the plastic does not tear at the predetermined breaking point, but remain spikes, is avoided by such a soft connecting bridge.

After positioning the plaster molding at a transition between the building component and thermal insulation or plaster layer a protective film is usually attached to the strip-shaped protection tab, in particular glued and stretched over the building component to protect it from dirt and damage during plastering. After the plastering, the protective film is removed, and the strip-shaped protective tab is separated from the base body of the plastering strip by the length of the soft connecting bridge is severed.

This separation can be done in any way, in particular, the strip-shaped protection tab can be manually removed from the base body of the plaster strip, which can be simplified by scribing or cutting the connecting bridge at the end of the plaster strip. Also, the connecting bridge by a cutting tool, for example a cutter knife are severed lengthwise to separate the strip-shaped protective tab from the base body.

When cutting through the soft material bridge, the soft connecting bridge section remaining on the base body forms a soft edge and thus a soft end of the plastering strip. This reduces the risk of injury to a minimum.

Sharp and jagged edge courses, which can occur when providing a connecting bridge as break-off material bridge from the same base material of the plaster strip, as well as the resulting injury risks are reliably avoided.

Furthermore, a uniform course of the base body-side end results with the connecting bridge section remaining thereon.

By providing the soft connection bridge, the plaster strip can be divided easily and reliably after installation, in which case the removal of the strip-shaped protective strip from the base body is understood here as meaning parts.

Characterized in that the severability of the soft connection bridge is ensured by a corresponding soft plastic material of the soft connection bridge, which differs from the hard material of the base body, and the material properties of the soft connection bridge in the temperature range usually occurring on construction sites from a few degrees below 0 ° C to about 30 ° C are substantially constant, a simple severability can be ensured under all temperature conditions occurring. Problems that result in the formation of the material bridge as break-off material bridge, which is made of the same material as the rest of the grout, such as too early unintentional breaking off of the protective tab, For example, when too thin training Abbrechmaterialbrücke, too laborious breaking the material bridge, for example, in too thick trained material bridge or at low temperatures, especially in winter, can be reliably avoided.

Furthermore, a screed strip according to the present invention can be produced more safely and with less rejection than screed strips with break-off material bridges made of the same material as the rest of the scraper bar, which often causes the problem that the break-off material bridge is made too thin and the Protection tab falls too easy or the material bridge is too thick and the protective flap accordingly sits too firmly on the base body turn.

The inventors have further found that as a base material for the base body and / or the protective tab of the plaster molding according to the invention also cheaper and less valuable plastics, such as. Regenerat, ie recycled plastic, or plastic with Regeneratanteil are suitable for conventional plaster molds rarely used come because after cutting the break-off material bridge of lower-value plastic such specks or spikes remain on the base body of the plastering strip. Due to the soft connection bridge, even with the use of cheaper and less valuable plastics for the base body and / or the protective tab, such stipples or points can be avoided. Such a cleaning strip according to the invention also offers a cost advantage.

The softness of the soft connection bridge can be adjusted in the production of the Shore hardness.

Unlike break-off material bridges, which are made of the same material or have the same strength as the rest of the plasterboard, can be in a soft connecting bridge uneven end curves of the base body Easily correct the plaster molding by simply peeling off or cutting off protruding edge areas made of soft connecting bridge material.

If both the base body and the strip-shaped protective tab are made of the same hard plastic material, then the plastic material of the connecting bridge is softer than these two components of the plaster bar.

A plaster strip according to the invention can be fixed to the building corner in any manner, for example. The plaster strip can be fixed to the building component, in particular glued, the plaster strip can also be fixed in position in a gap between thermal insulation and building component or attached to the insulation , All these possibilities can be used in the plasterboard according to the invention.

According to a first embodiment of the invention, the base body also has a portion attachable to the building component to secure the plaster molding to the building component.

According to a further embodiment of the invention, the connecting bridge has a thermoplastic elastomer TPE. This material is particularly suitable for the soft connection bridge because it provides sufficient rigidity to hold the strip-shaped protection tab in place during installation and plastering, and at the same time, the connection bridge can be easily severed to secure the strip-shaped protection tab from the base body of the plaster strip remove. These material properties and advantages are given in TPE over the entire temperature range occurring.

TPE also has the additional advantage that this material is UV-resistant, so there is no impairment of the material even in strong sunlight. This is even more important because of the edge of the base body remaining portion of the severed connecting bridge is often exposed to sunlight.

Other suitable materials for the connecting bridge are soft PVC and polyurethane.

According to a further embodiment of the invention, the base body and / or the strip-shaped protective tab on a rigid PVC. This material has proven itself for plaster moldings.

A plaster strip according to the invention can be made particularly reliable by extrusion.

According to a further embodiment of the invention, the connecting bridge is produced together with the base body and with the strip-shaped protective tab by coextrusion. Thus, the plastering strip according to the invention can be produced with the soft material bridge safely and with little waste.

According to a further embodiment of the invention, the material thickness in the region of the connecting bridge is lower than in the adjacent end pieces of the base body and the strip-shaped protective tab. By such a slightly reduced material thickness of the connecting bridge this can still hold the required rigidity to keep the strip-shaped protective tab during assembly and plastering in position. A connecting bridge with such reduced material thickness can be cut particularly easily to separate the strip-shaped protective tab.

According to a further embodiment of the invention, the material thickness of the soft connecting bridge in the central portion thereof is smaller than at the end portions thereof, with which the connecting bridge adjoins the end pieces of the base body and the strip-shaped protective tab. Especially the connecting bridge tapers towards its central portion and / or has a concave / convex cross-sectional profile. By this embodiment of the invention, a predetermined separation point is created by the middle portion of the soft connection bridge, in which the material thickness is the lowest, so that when separating the connecting bridge this is separated along this predetermined separation point, which brings a particularly favorable and uniform base body side Anputzleistenendverlauf with it.

According to a further embodiment of the invention, that portion of the base body which can be fastened to the building component is formed as a base wall.

According to a further embodiment of the invention, that portion of the base body which is intended for embedding in a Putzschnicht formed as a protruding Einputzschenkel with Putzabschlussseite.

According to a further embodiment of the invention, the Einputzschenkel has a stepped course.

According to a further embodiment of the invention, the base wall and the protruding Einputzschenkel with Putzabschlusseite, after separating the strip-shaped protection tab along the connecting bridge, against each other slidably formed to accommodate movements between building component and thermal insulation or plaster layer and compensate.

According to a further embodiment of the invention, the base wall and the protruding Einputzschenkel are in guide connection with each other, which allows a relative movement of the base wall to the protruding Einputzschenkel.

Such a guide connection may be designed in the manner of a bayonet, that is, as an extension provided on the base wall side, which protrudes into a receiving space on the plaster side or as an extension provided on the side of the plaster leg which protrudes into a base wall side receiving space.

Likewise, the base wall and the protruding Einputzschenkel by a so-called loop, so be connected by a flexible material area with each other, which ensures a relative movement of the base wall to the protruding Einputzschenkel.

In a plaster molding with a base wall and displaceably arranged protruding Einputzschenkel the soft connection bridge as the first connection strip between the strip-shaped protection flap and the base wall, in particular one end of the base wall, and / or as a second connection strip between the strip-shaped protection tab and the protruding Einputzschenkel with plaster finish side, in particular with the end of Putzabschlussseite be formed. It can therefore be provided only connecting strip which connects the strip-shaped protective flap with the base wall or with the protruding Einputzschenkel. Alternatively, two connecting strips may also be provided, of which the first connecting strip connects the protective flap to the base wall and the second connecting strip connects the protective flap to the protruding plastering leg.

According to a further embodiment of the invention, the base body for attachment to the surface of the building component via an adhesive tape or an adhesive strip.

According to a further embodiment of the invention, the base body for fixing to the surface of the building component via an expansion belt with delayed expansion, which seals against the surface of the building component and compensates for movement between the building component and thermal insulation or plaster layer.

According to a further embodiment of the invention, a protective lip is arranged in addition to the adhesive strip and / or the expansion band, in particular outside of the adhesive strip and / or the expansion band, which is made of a soft flexible material and which rests in the mounted state of the plaster strip on the building component and protects the adhesive strip and / or the expansion band from dirt and / or moisture and / or UV radiation. If this protective lip is also designed such that it is also impact-proof, it can also be called a sealing lip.

According to a further embodiment of the invention, the projecting Einputzschenkel is provided with Putzabschlussseite with a groove profiling for improved adhesion to the plaster.

According to a further embodiment of the invention, a Armierungsgewebeabschnitt is fixed to the protruding Einputzschenkel, which is embedded in the plaster.

The invention also relates to a building corner with a plaster molding of the type described above. The plaster molding is fixed to a portion of the base body to the building component, is connected to another portion of the base body to the insulation and is embedded with this further section in a plaster layer , In the assembled state of this building corner a protective film is fixed to the strip-shaped protective flap. This protective film spans at least a part of the building component, which is to be protected during assembly and / or during plastering from dirt and damage.

The invention also relates to a building corner with a plaster molding of the type described above, which is fixed to a portion of the base body to the building component and which bears with a further portion of the base body to the insulation and is embedded with this further portion in a plaster layer. In this building corner in the finished state, the strip-shaped protective tab is separated by cutting the soft connecting bridge of the base body of the plaster molding, so that the connecting bridge portion forms the end of the base body of the plaster molding with a soft end edge.

For these building corners, there are the same advantages and refinements that have been described above with respect to the plaster molding and are not repeated here again.

The connection bridge can also be referred to as a connection strip.

The invention is explained in more detail by means of embodiments with reference to the accompanying figures.

• FIG. 1 shows a side view of a first grout rail in the delivery condition; and
• FIG. 2 shows a side view of a second grout bar in the delivery state.

In both figures, the longitudinal extension of the plastering strip runs in a direction perpendicular to the plane of the drawing.

FIG. 1 shows a side view of a first grout 2 in the delivery state.

The plaster strip 2 comprises a base body 4 with an adhesive strip 24 fixed thereto for attachment to a component of a building and with a reinforcing fabric section 22 attached thereto, which is embedded in a plaster layer, and a strip-shaped protective strip 26, which is integrally connected to the base body 4. The adhesive strip 24 may be a PE sealing strip.

In principle, plaster strips can be fixed to a building corner in various ways.

In the embodiments explained with reference to the figures, the plaster strip is fixed to the building component, in particular adhesively bonded to the adhesive strip 24 or 46.

Alternatively, the screed can also be fixed in position in a gap between the thermal insulation and building component or attached to the thermal insulation. This is often a PE-sealing tape or an expansion belt of precompressed foam is used, which creates a sealing against the building component and is able to compensate for changes in the gap width.

The building component, on which the adhesive strip 24 rests, can be configured as a window / door frame, as a window sill, as a beam, as a metal connection or as a lisse.

The base body 4 of the first grout 2 comprises an in FIG. 1 horizontally shown base wall 6 with a fixed to the underside of adhesive strip 24, in the mounted state of the plaster strip 2 with its in FIG. 1 and abuts against the surface of the building component downwardly facing surface and creates a seal against it and, if necessary, additionally bonded to the surface of the building component.

If the element 24 is an expansion strip 24 with some expandability and shrinkability, spacing changes between the underside of the base wall 6 and the surface of the building component can be accommodated within certain limits, providing a good seal under changing conditions guaranteed.

Furthermore, the base body 4 has an approximately perpendicularly projecting from the base wall 6 Wegragschenkel 10. In the present embodiment, the Wegragschenkel 10 is in a right, so outside the middle of the base wall 6 located area and has a in FIG. 1 to the left, so inward-facing thermal insulation plant side 12, with the plasterboard 2 can be placed on a thermal insulation or a plaster layer, and a in FIG. 1 to the right, so facing outward plaster side 14, which is plastered. The outwardly facing plaster side 14 of the Wegragschenkels 10 and the top of the outside of the Wegragschenkel located portion of the base wall 6 are provided with a groove profiling 18 to increase the surface, which comes into contact with the applied plaster layer, and thus the adhesion of the To improve plaster layer on the plaster molding 2. The outside of the Wegragschenkel 10 located portion of the base wall 6 is also referred to as Putzendseite 16, because the applied plaster ends here. The outer end edge of the base wall 6 and thus the cleaning end side 16 accordingly forms a Putzendkante for the applied plaster layer.

The left, so located within the Wegragschenkels 10 section of the base wall 6 and the underlying portion of the adhesive strip 24 are pushed during assembly of the plaster strip in a gap between thermal insulation or existing plaster layer and building component and fill this gap.

Accordingly, the upper side of the section of the base wall 6 situated within the leg 10 can also be referred to as the thermal insulation system side 8, in particular as the gap-side thermal insulation system side 8.

In the FIG. 1 inwardly directed surface of the Wegragschenkels 10 may also be referred to as surface-side thermal insulation plant side 12.

Approximately in the middle of the thermal insulation plant side 12 is an ultrasonic welding 20, by means of which the in FIG. 1 vertically upwardly extending Armierungsgewebeabschnitt 22 is attached to the base body 4.

At the in FIG. 1 right, outer end of the base wall 6 is followed by a strip-shaped protective tab 26. The front of the protective tab 26 is flat and carries there an adhesive layer 28. On the adhesive layer 28 may be an in FIG. 1 Not shown protective film are glued, extending from the plaster strip 2 in FIG. 1 to the right, that extends to the outside.

If you now imagine a window sill, on the surface of each on the left, on the right and on the upper side of a plaster bar is glued, then it is clear that the protective film covers the entire opening between the three plaster strips and in this way the window stock protects against dirt and damage when applying the plaster. On the lower side, where the windowsill is positioned, there is no further plastering strip.

On its rear side, the protective strap 26 has a spacer web projecting substantially at right angles to the rear. The spacer bar is so high that the protective tab 26 is supported on the back of the spacer bar on the building component such that the front of the protective tab 26 is substantially parallel to the front of the building component. The base body 4 is connected to the strip-shaped protective tab 26 connected by means of a strip-shaped connecting bridge 30 made of a softer material against the harder plastic material of the base body 4 and / or the strip-shaped protective tab 26.

In the present embodiment, the connecting bridge is designed as a TPE connecting bridge 30, ie connecting bridge of a thermoplastic elastomer, and both the base body 4 with base wall 6 and Wegragschenkel 10 and the strip-shaped protective tab 26 are made of a hard plastic, in particular of a rigid PVC produced. As an alternative to the formation of the connecting bridge 30 made of a thermoplastic elastomer, this can also have a soft PVC or a polyurethane.

The base body 4 with the base wall 6 and with Wegragschenkel 10 and the strip-shaped protective tab 26 can be advantageously prepared by extrusion, the TPE connecting bridge 30 is prepared by coextrusion. This ensures reliable and fast production of the plaster molding.

Extrusion can reduce rejects, and the TPE connection bridge can be manufactured reliably with consistent material thickness, so that the properties required on site, namely sufficient rigidity with good severability regardless of the prevailing temperatures, are always given. This is a great advantage over Abbrech-material bridges with very low wall thickness at which manufacturing tolerance-related wall thickness deviations from the target wall thickness often to reject already in production, for example by accidental breaking off of protective straps due to too thin made break-material bridges, or lack of processability lead to the construction site, for example, too early breaking the protective tab in too thin break-bridge material or too much effort and ugly and one Risk of injury forming break-off material edges if the break-off material bridge is too thick.

After the extrusion, only the adhesive strip 24 must be applied to the underside of the base wall 6, the reinforcing fabric section 22 attached by means of ultrasonic welding 20 to the Wegragschenkel 10 and the strip-shaped protective tab 26 are provided with the adhesive layer.

On the one hand, the TPE connecting bridge 30 provides enough stability for the strip-shaped protective strip 26 to abut against the building component, not shown here, at a transition between the building component and the thermal insulation / plaster layer, even if the adhesive film is attached to the adhesive layer 28 and spans the building component.

On the other hand, the TPE connection bridge 30 is so soft that it can be severed in a simple manner to separate the strip-shaped protective tab from the base body 4 after completion of the cleaning work.

This severing can take place by pulling off the strip-shaped protective strip while simultaneously cutting through the TPE connecting bridge 30 along the longitudinal extension of the plastering strip 2, possibly supported by the cutting of the TPE connecting bridge 30 at an end region of the plastering strip. After severing the TPE connection bridge 30, a material strip of soft TPE material located at the outer end of the base wall 6 or the plaster end side 16 remains on the base body 4, so that no sharp edge can arise at this point, which ensures a favorable appearance and prevents injuries.

As in FIG. 1 can be clearly seen, the material thickness in the middle region of the TPE connection bridge 30 is less than at the end regions with which the TPE connection bridge 30 at the outer end of the base wall 6 and Putzendseite 16 and connects at the inner end of the strip-shaped protection tab 26. As a result, an even more improved severability of the TPE connection bridge 30 is made possible, and a particularly uniform edge profile results after severing the TPE connection bridge 30, since such a TPE connection bridge 30 is advantageously separated along its center region with reduced material thickness, which also increases contributes a particularly advantageous appearance. By providing such a TPE connection bridge 30, a separation of the strip-shaped protection tab 26 can be achieved with little effort independently of the temperature prevailing at the construction site. An unintentional, too early separation of the protective strap 26 is avoided as well as an excessively high force to separate the protective strap 26, as often occurs in thick Abrechmaterialbrücken and is further increased by prevailing at the site cold temperatures.

Likewise, the TPE connection bridge 30 can also be severed by a cutting tool, for example a cutter knife, after the plastering has taken place in order to separate the strip-shaped protective tab 26.

The above with reference to FIG. 1 described plaster molding 2 is representative of a variety of differently constructed one-piece plaster moldings described by way of example.

Also included in the present invention are one-piece plaster moldings with a so-called loop solution, that is to say a flexible material section which connects a base region to a displaceable region.

FIG. 2 shows a side view of a second grout 32 in the delivery state.

As with the first plaster strip 2, the second plaster strip 32 also has a base body, which can be fastened with a section to the building component and is provided with a further section for embedding in a plaster layer, and a strip-like protective strip 26, which is provided with connected to the base body.

The strip-shaped protective strip 26 with the adhesive layer 28 of the second plastering strip 32 coincides with the strip-shaped protective strip 26 with the adhesive layer 28 of the first plastering strip 2 and will not be explained again below.

In contrast to the first plaster molding 2, in which the base body 4 is integrally formed, the base body of the second plaster molding 32 is divided into a base region 34 and a front region 36 which can be displaced relative to the base region 34 in the direction of changing the base region 34 to the front region 36.

The base region 34 comprises a base wall 38 with an adhesive strip 46 attached to its underside, which sealingly bears against the surface of the building component with its underside in the installed state of the plastering strip 32 and possibly is adhesively bonded thereto.

If it is an expansion strip 46 of a flexible material, so this can be compressed and expand again so as to compensate for changes in distance between the bottom of the base wall 38 and the surface of the building component within certain limits.

At the right outside end of the base wall 38, a protective lip 44 extends downwards. This protective lip 44 is formed, in particular, from softer flexible plastic material than the hard plastic material of the base region 34 and thus has a certain flexibility. Such a flexible Protective lip 44 applies in the installed state of the second grout 32 to the surface of the building component at a position outside of the adhesive strip 46 and thus reliably prevents moisture from reaching the adhesive strip 46.

The protective lip 44 can be coextruded, in particular, together with the base wall 38 and the guide extension 40 explained in more detail below, with the front region 36 and the strip-like protective strip 26 and the TPE connection bridges 64 and 66 explained below.

A guide extension 40 protrudes upward from the base wall 38 and is integrally formed therewith. This guide extension 40 comprises an uppermost widened end head 42, an underlying extension wall region of lesser wall thickness and a connection to the base wall 38 forming extension wall region of further reduced wall thickness.

The displaceable front portion 36 is divided into a Wegragschenkel 48 with stepped course, which is formed by a rear receiving space 60 with an inner heat insulation plant side 50 and outer plaster side 55 and with a front Wegragschenkelabschnitt with inner plaster side 52 and outer plaster side 54, and in a at the lower outer end of the outer plaster side 55 attaching and outwardly extending Putzendseite 56th

The receiving space 60 is dimensioned so that the front end of the end head 42 with completely in the receiving space 60 located Führungsfortsatz 42 and thus upon contact of the rear end surface of the side walls 50 and 55 of the receiving space at the front of the base wall 38 at a small distance to the upper wall the receiving space 60 is positioned.

At the lower end of the inner sides of the receiving space 60, opposite guide projections 62 abut and extend so far inside, with respect to the symmetry axis of the receiving space 60, that they receive and guide the guide extension 40 therebetween. In the in FIG. 2 In the position of the guide extension 40 shown, the guide projections 62 engage the lowermost region of the reduced-wall guide extension 40 and hold this guide extension 40 and thus the entire base section 34 with respect to the displaceable front section 36 in the minimal displaced position. The guide projections 62 may consist of a plastic material which is softer than the material of the displaceable front region 36.

If one imagines that the TPE connection bridges 64 and 66, which will be described in more detail below, are severed, the front region 36 can be displaced relative to the base region 34, up to a maximum displacement position at which the guide projections 62 on the end head 42 strike. As a result, movements between thermal insulation / plaster layer and building component can be compensated in a particularly advantageous manner.

From a central region of the upper wall of the receiving space 60, the upper Wegragschenabschnitt extends upwards. The inner plaster side 52 and the outer plaster side 54 of the upper Wagragschenkelabschnitts, the outer plaster side 55 of the outer wall of the receiving area 60 and the Putzendseite 56 are provided with a channel profiling 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 of the front wall of the receiving space 60.

On the outer plaster side 54 of the Wegragschenkels 48 is an in FIG. 2 attached to the front extending reinforcing fabric portion 22, by means of an ultrasonic welding 20 shown here as an example.

The connecting bridge between the base body 34, 36 and the strip-shaped protective tab 26 is in the second grout 32 as a first TPE connecting bridge 64 between the outer end of the base wall 38 and the lower portion of the inner end of the strip-shaped protection tab 26 and as a second connecting bridge 66 between the outer end of the Putzendseite 56 and the upper portion of the inner end of the strip-shaped protective tab 26 is formed. These TPE connection bridges 64 and 66 may also be referred to as connection strips.

Like the TPE connection bridge 30, the TPE connection bridges 64 and 66 are also made of a plastic material that is softer than the material of the base region 34, the displaceable front region 36 and / or the strip-like protection flap 26, on the one hand providing sufficient stability for the strip-like protection flap 26 and On the other hand, a simple and secure separability of the connecting bridges 64 and 66 and thus to ensure a simple and safe removal of the strip-shaped protective tab 26.

For this purpose, the connecting bridges 64 and 66 are in particular made of a TPE, ie a thermoplastic elastomer, which offers these properties.

A particularly suitable production method for the second grout 32 is the coextrusion manufacturing process. Here, the base portion 34 except for the protective lip 44 and the adhesive strip 46 to be attached later, the sliding front portion 36 except for the guide projections 62 and the reinforcing fabric portion 22 to be attached later and the strip-like protective sheet 26 may be made of a relatively hard plastic material except for the adhesive layer 28 to be attached later in particular, are extruded from hard PVC, and at the same time, the protective lip 44, the guide projections 62 and the connecting bridges 64 and 66 may be made of one or more softer ones Plastic materials are coextruded. Preferably, the protective lip 44, the guide projections 62 and the connecting bridges 64 and 66 may be coextruded from a common softer plastic material, in particular from a thermoplastic elastomer TPE.

The advantages of forming the connecting bridges 64 and 66 from a softer plastic material correspond to the advantages given above with respect to the first plastering strip 2. In a nutshell, the plaster molding can be produced with such connecting bridges 64 and 66 safely and with less waste, and the strip-shaped protective flap 26 can be separated easier and safer, especially in cold temperatures.

The result is a soft outer edge for the cleaning end 56 and the base wall 38, which both avoids injuries and improves the appearance.

In addition, the connecting bridges 64 and 66 may have a thinner material thickness in their middle in order to ensure a predetermined separation point and a uniform edge course there.

As an alternative to the formation of two connecting bridges 64 and 66, only one connecting bridge can be provided, either between the outer end of the base wall 38 and the inner end of the strip-shaped protective strip 26 or between the outer end of the Putzendseite 56 and the inner end of the strip-shaped protective flap 26th ,

When installing the second grout 32, no gap must be present. The plaster molding strip 32 is applied to the heat insulation and with the adhesive strip 46 to the building component with the thermal insulation plant side 50 and glued. Thereafter, the protective film is stretched over the building component and fixed to the adhesive layer 28. Then the plastering takes place Front region 36. In this case, the plaster layer extends over the entire provided with gutter profiling 58 area of the movable front portion 36, so on inner plaster side 52 and outer plaster side 54 of the front Wegragschenkelabschnitts, over the front and outer wall of the receiving area 60 and the Putzendseite 56 to Putzendkante, which is defined by the end of Putzendseite 56. In addition, the cleaning material also penetrates the reinforcing fabric section 22.

After the plastering done, the TPE connection bridges 64 and 66 are separated, for example, pulled off by hand, if necessary by cutting the ends of the connecting bridges 64 and 66. Thus, the strip-shaped protection tab 26 can be easily separated.

By severing the connecting bridges 64 and 66, which have previously held together the base region 34 and the displaceable front region 36 via the strip-like protective flap 26, the displaceable front region 36 is now decoupled from the base region 34 and can be replaced by the construction with guide extension 40, end cap Move 42 and receiving space 60 with guide projections 62 relative to the base wall 38 and thus compensate for movements between thermal insulation and plaster layer and building component.

The second plastering strip 32 is a two-part plastering strip described by way of example in which two regions 34 and 36 can be displaced relative to one another in order to compensate for movements between the thermal insulation / plaster layer and the building component.

Other two-part plaster moldings are also covered by the invention, in particular two-part plaster moldings which are at least partially inserted into a gap between the thermal insulation and the building component.
