Description

The invention relates to a plaster molding, a finishing rail and a plaster molding.

In the construction of buildings is usually proceeded so that window bars and door frames, which are firmly connected to the building fixed window or door frame, are inserted into the corresponding wall openings of the shell and fastened there. In a later phase, the shell is plastered outside and inside. Here, in particular on the outside of the structure of the connection of the plaster to the window sash or door frame to the critical point, because the plaster abuts the front of the material of the window sash or door sill and there does not form a perfect bond. As the plaster shrinks slightly during drying, since window and door sills are exposed to vibrations, for example by violent slamming of 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 or door frame. Here moisture can then penetrate, which permanently damages the window floor, the door frame or the plaster or the insulation, for example leads to crumbling of the plaster. For this reason, plaster moldings are often provided at the transition between the window or door frame to the plaster, which decouple the window or door frame from the plaster and at the same time provide a seal therebetween. Such a plaster strip is for example from the EP 0 875 641 A2 known.

A similar problem arises in the case of end sections of structural insulations and structural sound insulation. Structures are nowadays more and more provided on their outside with thermal insulation, which consist for example of rigid foam or fiberboard. Thermal insulation on building walls usually has a lower end just above the surface of the soil or a soil attachment approaching the building wall. The lower end of the thermal insulation is a critical area because moisture can penetrate from underneath between the building wall and the thermal insulation and between the thermal insulation and the outer plaster, which can lead to damage up to crumbling plaster. Therefore, in the lower end of the thermal insulation often end rails are used, which are attached with a first leg to the building and on the second leg, the insulation rests with its end face. Because the Outside of such insulation panels is often provided with external plaster, such a finishing rail a reliable plaster finish must be guaranteed to prevent cracks in the plaster and even crumbling of the plaster. Such a termination bar is for example from the DE 195 39 526 A1 known.

A very similar problem arises even with plastered building corners. At building corners plaster corner strips are often applied, which serve to ensure a reliable completion of the plaster layer on the first side of the building corner and a reliable conclusion for the plaster layer on the second side of the building corner and to avoid the crumbling of plaster on the building corner , Such a plaster cornice is for example from the DE 100 38 279 A1 known.

All such plaster strips, finishing rails and plaster corner strips has in common that essential components of them are often made by insulation for insulation reasons by extrusion. These plaster strips, finishing rails and plaster corner strips are usually extruded from hard plastic, especially PVC.

All such plaster strips, finishing rails and plaster corner strips is still common that they are available on the site in fixed lengths and that it will be cut off at the construction site, the required plaster strips, finishing rails and plaster corner strips in the desired length. This creates waste, usually several short pieces that need to be disposed of.

It is therefore an object of the present invention to provide a plaster molding, a finishing rail and a plaster molding, which can be produced environmentally friendly and where waste accumulating on the site can be disposed of environmentally friendly.

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

The fixing area and the plastering area are formed as a common extrusion part or as separate extrusion parts and have a material whose main component is a renewable raw material.

A finishing rail according to the invention for structural heat insulation or building sound insulation comprises an angle rail whose first leg is provided for attachment to the structure and the second leg for abutment against a termination end side of the insulation; and an outer bar attached to the end portion of the second leg of the angle rail and having an outer leg for engagement with the outside of the insulation. The angle rail and the outer bar are formed as a common extrusion or as separate extrusion parts. The angle rail and / or the outer bar have a material whose main component is a renewable raw material.

A trim corner strip according to the invention for arrangement on a vertical or a horizontal building corner, in particular a building corner provided with thermal insulation, comprises a first leg for engagement with the building on the first side of the building corner; and a second leg for engagement with the structure on the second side of the building corner. The first and second legs are formed as a common extrusion or as separate extrusions. The first and / or the second leg comprise a material whose main component is a renewable raw material.

The plaster strip according to the invention ensures a permanently tight transition to a building component. Likewise, the end rail according to the invention ensures a permanent and secure closure for building thermal insulation or structural sound insulation. Likewise, a permanently dimensionally stable corner is ensured by a plaster corner strip according to the invention.

Due to the formation of the fixing area and / or the Anputzbereichs (in the plaster molding), the angle rail and / or the outer strip (at the end rail) and the first and / or second leg (in the plaster corner molding) of a material whose main component a renewable raw material, and thus mainly from renewable raw materials, the resources available in nature can be used, and a considerable amount of petrochemical or similar materials, which are used for the production of such strips / rails made of hard plastic could be replaced by a renewable resource. This protects the resources and guarantees an environmentally friendly production.

According to one finding by the inventor, renewable raw materials can be extruded with the addition of at least one further component which ensures cohesion and, after extrusion, are well suited to the requirements of the plaster molding according to the invention, the finishing rail according to the invention or the plaster molding of the type described above.

While the plaster strip according to the invention, the inventive finishing rail and the plaster corner molding according to the invention, which in the installed state only slightly come into contact with water in the installed state permanently dimensionally stable and can fulfill their function, the disposal is significantly simplified due to the main component of a renewable resource , Therefore, on the construction site resulting waste from such strips / rails, usually several short pieces, can be disposed of more easily and decomposes after a manageable period in the ground, which makes the bar / rail according to the invention also in terms of waste disposal significantly more environmentally friendly.

As an alternative to the disposal of such waste, they can also be fully recycled and used for the production, in particular extrusion of new plaster moldings, finishing rails and plaster corner moldings.

The weight or volume fraction of such mostly quite short waste strips / rail pieces is relatively small relative to the total amount of strips / rails used.

In general, all conceivable designs of such plaster strips, such cover rails and such plaster corner strips comprising the material of the invention, the main component of which is a renewable raw material of the plaster strip according to the invention, of the invention and.

According to a first embodiment of the plaster molding according to the invention, the fixing area and the plastering area are integrally formed. In this case, both the fixing area and the grooming area comprise a material whose main constituent is a renewable raw material. Such a plaster molding seals the building transition reliably and is relatively simple.

According to a further embodiment of the plastering strip according to the invention, the fixing region has an adhesive strip for attachment to the first building component. By means of such an adhesive strip, the plaster strip is reliably connected with its fixing area with the building component.

The term "adhesive strip" also includes a strip of adhesive applied. The design can be such that the adhesive strip, which adjoins the remaining plaster strip on one side and can be adhered to the first building component on the other side, already constitutes the fixing region as such. It is emphasized, however, that there are alternative ways of forming the fixing area, in particular screwing the plaster molding on one of the two building parts or pinching in a gap between the first component of the building and the thermal insulation or fixing or fixing to the insulation.

According to a further embodiment of the plaster molding according to the invention, the plastering area is provided with a groove profile for improved adhesion to the plaster. Through such groove profiling, the surface of the plastering area, with which the plaster enters into a bond increases, and thus improves the adhesion.

In a further embodiment of the plastering strip according to the invention, a reinforcement fabric section is attached to the plastering area, which is intended for plastering. The Armierungsgewebeabschnitt can be formed for example in the form of a coated with alkali-resistant material fiberglass mesh. After applying the plaster, the Armierungsgewebeabschnitt is below the plaster surface, in most cases, he is in turn attached by means of filler to the ground. The reinforcing fabric section improves the adhesion of the plaster to the substrate and ensures the permanent crack-free of the plaster.

According to a further embodiment of the plaster strip according to the invention, a detachable or breakable strip-shaped protective strip is provided. At this protective tab on which an adhesive strip can also be provided, a film can be attached, which spans the window frame and the window or the door frame and the door, or the like, and protects against dirt and damage during the plastering. After the plastering is done, this protective tab is removed or disposed of by separating or canceling the rest of the cleaning strip, which is when the Protective tab also has a material whose main ingredient is a renewable resource, especially environmentally friendly.

According to a further embodiment of the plastering strip according to the invention, the fixing area and the plastering area are formed separately from one another in such a way that a relative movement between the fixing area and the plastering area is made possible by separating a strip-shaped protective strip by means of a guide connection. In this case, the cleaning strip is formed in two parts, with one part being formed by the fixing area and the other part by the plastering area. By such a relative mobility between Festlegungs- and Anputzbereich material movements, for example as a result of temperature fluctuations or dwindling between the fixedly connected to the first building component fixing area and the permanently connected to the plaster layer Anputzbereich can be easily and reliably compensated by a relative movement of the Anputzbereichs to Fixing area allows. At the same time, the sealing function of the plaster molding is maintained without damaging the plaster or the plaster.

According to a further embodiment of the plaster strip according to the invention, the fixing and the plastering area are connected to one another via a flexible material section, which is also referred to as a loop, which permits relative movement between the fixing area and the plastering area. Also in this embodiment, the grout bar material movements, for example due to temperature fluctuations between the first and the second building component compensate, by a movement, such as an elongation of the flexible material portion. At the same time the sealing function of the plaster molding is maintained without the plaster being damaged.

According to a further embodiment of the plasterboard according to the invention this has an expansion strip which is designed so that it - possibly after releasing a Einperrbereichs - expands in the direction of one of the two building components towards and applies it, so as a seal between the two To ensure components.

According to a first embodiment of the end rail according to the invention the outer strip is glued to the angle rail or attached to the angle rail. Both types of connection can be z. B. perform easily at the site and result in a lasting, even in adverse weather conditions stable connection.

According to a further embodiment of the inventive end rail, the outer bar has a closure end-side leg, which is provided for abutment against a closure end face of the insulation. With such a front-end leg, the outer bar can be attached to the insulation easily and accurately positioned.

According to a further embodiment of the invention, the angle rail and the outer strip are connected to one another by means of an adhesive strip, in particular by means of an adhesive strip provided between the second leg of the angle rail and the end-face leg of the outer strip. This adhesive tape, which also includes a quantity of adhesive applied, reliably and permanently bonds the angle rail and the outer panel, providing a good seal therebetween.

According to a further embodiment of the closure rail according to the invention a Armierungsgewebeabschnitt for applied to the insulation plaster is attached to the outer bar, which is intended for plastering. The Armierungsgewebeabschnitt can be formed for example in the form of a coated with alkali-resistant material fiberglass mesh. After applying the plaster, the Armierungsgewebeabschnitt is below the plaster surface, in most cases, he is in turn attached by means of filler to the ground. The reinforcing fabric section improves the adhesion of the plaster to the substrate and ensures the permanent crack-free of the plaster.

According to a further embodiment of the invention, the outer rail has a further leg, which forms a drip nose for water. This further leg can protrude, for example, in the installation situation at the lower end of the insulation down and reduce the proportion of water that passes from the outside in the direction of thermal insulation and towards the building. This keeps the angle rail drier and also prevents, in the case that the outer bar is glued to the angle rail, that too much water gets to the adhesive strip.

In accordance with a further embodiment of the closure rail according to the invention, a flexible transitional area is provided between the outer leg and the closing end-side leg of the outer bar. This can be a change in position between the Allow outer leg and the final front-side leg in a certain angular range, so that the end rail according to the invention can be used for different installation situations.

According to a further embodiment of the end rail according to the invention, the transition region has an insertion region in the transverse direction for a plug connector. Thus, a connector can be transversely inserted into the transition region, and the terminus can be connected and aligned with a transversely disposed terminus. In the adjacently arranged end rail is then preferably also provided a plug-in area in the transverse direction, in which the connector can be inserted. Thus, a fixation of the two adjacent end rails can be ensured.

According to a further embodiment of the end rail according to the invention, the second leg of the angle rail forms a step-shaped profile, which is arranged in particular in its outer end region. In particular, the outer end region may be at a height level below the height level of the remaining portion of the second leg of the angle rail. On the outer end portion of the second leg, the outer bar is often glued or plugged. It can thus be achieved that the upper side of the second leg of the angle rail and the upper side of the end front side leg of the outer strip are at the same height level, which allows a favorable connection to the heat insulation arranged above it.

According to a first embodiment of the trim strip according to the invention, a plastering area is formed by at least one of the legs. This facilitates the plastering of the plaster molding.

According to a further embodiment of the trim strip according to the invention a reinforcing fabric section is fixed in at least one of the legs, in particular in both legs, on the side facing away from the plant side, which is intended for plastering. The Armierungsgewebeabschnitt can be formed for example in the form of a coated with alkali-resistant material fiberglass mesh. After applying the plaster, the Armierungsgewebeabschnitt is below the plaster surface, in most cases, he is in turn attached by means of filler to the ground. The reinforcing fabric section improves the adhesion of the plaster to the substrate and ensures the permanent crack-free of the plaster.

According to a further embodiment of the trim strip according to the invention a particularly flexible transition region between the first and the second leg is provided. This can allow a change in position between the two legs in a certain angular range, so that the plaster corner strip according to the invention can be used for different installation situations.

According to a further embodiment of the trim strip according to the invention, the transition region is provided with a groove-like profiling at least on the side facing a leg to be armed. By such a channel profiling, the surface of the leg, with which the plaster enters into a bond increases, and thus improves the adhesion.

According to a further embodiment of the plaster molding according to the invention, the transition region has an insertion region in the transverse direction for a connector. Thus, a connector can be inserted in the transverse direction in the transition area, and the plaster molding can be connected to an adjacent, or above / below arranged plaster corner molding. In the adjacently arranged plaster corner strip is then preferably also provided an insertion in the transverse direction, in which the connector can be inserted. Thus, a fixation of the two adjacent plaster corner strips can be ensured.

The first plaster strip 2, the second plaster strip 26, the end rail 68 and the plaster corner strip 96 are described below representative of any plaster strips, finishing rails and plaster corner strips, in which at least one main area has been made by extrusion from a material whose Main component is a renewable raw material, and thus represents an extrusion of a material whose main component is a renewable raw material. The extrusions are inexpensive to manufacture and are characterized by a consistent over their entire length profile cross-section.

Fig. 1 and 2 show the plaster strips 2 and 26 respectively in the delivery state, in which the strip-shaped protective strap has not yet been separated.

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

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

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

The fixing area 4, the plastering area 10 and the strip-shaped protection strip 22 have been jointly produced by extrusion from a material whose main constituent is a renewable raw material, which will be described in more detail below.

The fixing area 4 is presently of a in Fig. 1 horizontally extending base wall 6 and an adhesive strip 8 fixed thereto, which is intended for attachment to a first building component, such as a window or door frame. The first building component, on which the adhesive strip 8 is applied, can also be designed as a window sill, as a beam, as a metal connection, or as a lisse.

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

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

The Armierungsgewebeabschnitt 18 is presently connected to the Wegragschenkel 12 by means of a compound, which is exemplified here as Ultraschallverschweißung 20, respectively.

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

On the construction site, the plastering strip 2 is first cut to the appropriate length predetermined by the dimensions of the window or door opening and then attached to the transition between the window / door frame and thermal insulation by placing the plastering strip 2 with its fixing region 4 in the gap between window and door frames. or door frame and insulation is inserted so that the plaster strip 2 rests with the top of its base wall 6 on the gap-side front side of the insulation, rests with the back of her Wegragschenkels 12 on the outside of the insulation and the adhesive strip 8 on the surface of the window or door frame is glued.

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

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

As an alternative to providing an adhesive strip 8, the element 8 can also be designed as an expansion strip with a certain expansion and shrinkability, without the need for gluing on its side facing the window or door frame. In this case, an insertion and, as it were, a bracing in the gap or attachment to the insulation takes place. As a result, distance changes between the bottom of the base wall 6 and the surface of the window or door frame can also be compensated within certain limits, which ensures a good seal under changing conditions.

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

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

Unlike the integrally formed first plaster strip 2, the second plaster strip 26 is now formed in two parts, with a Festlegungsbereich 28 and a displaceable for this purpose grooming area 40th

The fixing region 28 comprises a base wall 30 with an adhesive strip 32 attached to its underside, which sealingly bears against the window or door frame with its underside in the mounted state of the plastering strip 26 and is optionally adhesively bonded thereto.

If it is an expansion strip 32 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 30 and the surface of the window or door frame within certain limits.

At the right outside end of the base wall 38, a protective lip 34 extends downwards. This protective lip may be formed of a softer flexible plastic material and thus have a certain flexibility. Such a flexible protective lip 34 applies in the installed state of the second plaster strip 26 to the surface of the window or door frame, namely at a position outside of the adhesive strip 32 and thus reliably prevents moisture can reach the adhesive strip 32. The protective lip 34 can be coextruded, in particular together with the base wall 30 and the guide extension 36, which will be explained in more detail below, with the plastering area 40 and the strip-shaped protective strip 60.

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

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

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

If one imagines that the break-off material bridge or bridging material bridges 62 of the fixing region 28 and the displaceable plastering area 40 are severed to form the strip-like protective tongue 60, the grooming area 40 can be displaced relative to the fixing area 28, up to a maximum displacement position, in which the guide projections 44 abut against the end head 38. As a result, movements between thermal insulation / plaster layer and window / door frame can be compensated in a particularly advantageous manner.

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

On the outer plaster side 52 of the Wegragschenkels 46 is an in Fig. 2 attached to the front extending Armierungsgewebeabschnitt 64, by means of an ultrasonic welding 66 shown here as an example.

When installing the second plaster strip 26 no gap between thermal insulation and window / door frame must be present.
On the construction site, first the plaster strip 26 is cut to the appropriate, predetermined by the dimensions of the window or door opening length and then attached to the transition between window / door frame and insulation by applying the heat insulation plant side 48 to the insulation and with the adhesive strip 32 applied to the window / door frame and glued. Thereafter, the protective film is stretched over the window or door frame and fixed to the adhesive layer of the strip-shaped protective flap 60. Then, the plastering of the plastering area 40, optionally after previously done applying putty behind the Armierungsgewebeabschnitt 64. This filler can in particular fill the gap between the outside of the insulation and Armierungsgewebeabschnitt 64. At the Cleaning the plaster layer extends either over the entire, provided with channel profiling 58 area of the plastering area 40 or, if filler has been applied, on the outer plaster sides 52, 54 and the cleaning end side 56 to Putzendkante defined by the end of Putzendseite 56 is.

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

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

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

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

In the Fig. 3 shown end rail 68 includes an angle rail 70 and an outer strip 80 connected thereto.

The angle rail 70 has a first leg 72, which is provided for engagement with a building, not shown here, for example, on a wall, and which can be attached thereto, for example, by bolted bolts or screws, and a second, substantially horizontally extending Leg 74, which attaches to the underside of the first leg 72, from there continues horizontally outwards and at its end remote from the wall has a step 76 down.

The outer strip 80 furthermore has a substantially horizontally extending end-side limb 82 and an upwardly projecting outer limb 84 connected therewith via a transition region 76. The end-side limb 82 is above the step 76 of the second limb 74 of the angle rail 70 arranged and adhered by means of a foam adhesive tape or compressed sealing tape 78 on the recessed down Stufenendbereich 76. In this case, the top of the second leg 74 (except for the portion of the step 76) and the top of the end face leg 82 in the present example form a plane.

On the outside of the outer leg 84, a reinforcing fabric portion 92 is connected by means of suitable fasteners, which in the present case are designed as ultrasonic welds 94.

The transition region 86 between the end-side leg 82 and outer leg 84 is rounded in the present embodiment and describes approximately a half or two-thirds circle with an opening obliquely inwardly above, so that here in the transverse direction a plug-in area is formed for a connector. At the obliquely downwards inwardly and obliquely upwardly outward outer wall regions, a groove profiling 104 is formed in each case, and the right outer wall region of the transitional region 86 forms a plaster removal edge or a cleaning end side.

Further, a drip lip 90 is provided which extends obliquely inwardly from the right lower end portion of the transition portion 86 downward. Such a drip lip lip 90 ensures that the underside of the angle rail 70 remains dry and that the proportion of water that can reach the adhesive strip 78 is minimized.

When using the end rail 68, one normally operates such that, optionally after cutting the end rail 68 to the appropriate predetermined length, first the angle rail 70 is secured to the building wall, usually a plurality of angle rails 70 are fastened one after the other along the length of the wall can be used, wherein at the transitions with overlap can be worked or where at the junctions connectors which engage in the transition regions 86, each connecting two adjacent end rails 68 together.

Then, the outer panel 80 is glued, usually several, one after the other along the length of the angle rails 70. Then the thermal insulation is introduced, in such a way that they lie with their building side against the first limb 72 and above against the wall and that they rest with their underside on the second limb 74 of the angle rail 70 and the end face limb 82. When introducing and placing the insulation of the outer leg 74 can be pivoted together with Armierungsgewebeabschnitt 92 to the outside. The insulation is fixed in the usual way on the wall.

Now the Armierungsgewebeabschnitt 92 is attached from the outside with putty on the outside of the thermal insulation. It is understood that further reinforcing fabric, which is not shown, overlaps the reinforcing fabric section 92 at the top and is likewise fastened to the insulation. After the putty has tightened or hardened, a plaster layer is applied on the outside. Here, the in Fig. 3 the outermost transition region portion 86 serve as a trigger edge.

On the underside of the first leg 98, by means of suitable connections, which are shown here by way of example as ultrasonic weldings 112, a first reinforcement fabric section 110 is attached, which runs in the direction of the first leg 98 to the left. Likewise, on the outside of the second leg 100, a second reinforcement fabric portion 114 is attached by means of suitable connections, which are exemplified herein as ultrasonic welds 116. This second Armierungsgewebeabschnitt 114 extends in the direction of the second leg 100 upwards.

The outer wall region of the transitional region 102 pointing to the lower left and pointing to the upper right is in each case provided with a channel profiling 104 for improving the adhesion of the plaster.

The lowermost wall portion of the transition region 102 forms a first plaster removal edge 106, and the rightmost wall portion of the transition region 102 forms a second drainage edge 108. By bending the legs 98 and 100 toward one another, the trim molding 96 can approach virtually any required angle be set in a corner.

When plastering building corners, the procedure is as follows. First, the trim cornice 96, applied in practice a plurality of adjacent or stacked plaster corner strips 96 to the building corner and connected in the usual way with the building, for example by the shooting of bolts. Here you can work with overlap, or it can be connected together by connectors or spigot, which are inserted into the transition regions 102 of the adjacent plaster corner strips 96 adjacent plaster facing corners. Then the Armierungsgewebeabschnitte 102 are attached from the outside with putty on the building walls on both sides of the building corner, and then further not shown Armierungsgewebeabschnitte can be attached and also secured with putty on the building wall. Now the plaster is applied to both sides of the building corner from the outside on both walls, wherein the plaster removal edges 106 and 108 can specify here the thickness of the applied plaster layer. After hardening the plaster layer, the building corner is plastered ready.
