Abstract

In order to provide an edge-protecting border which can be easily produced, is not susceptible to thermal changes in length and is of an increased stability, in particular dimensional stability, the invention provides a process for producing an edge-protecting border with an, in particular, plastic angle profile having two legs which are positioned one upon the other and to which there are connected, to form the extension of the same, reinforcement mats, as corner reinforcement for a heat-insulating layer or masonry-wall corner bearing the fair-faced plaster, the reinforcement mats being fixed on the angle profile by heating the latter, and the border strips of the reinforcement mats projecting beyond the outer longitudinal borders of the angle profile. Said process is distinguished in that the extruder angle profile is provided with at least one bead on each of its legs, and the reinforcement mats, in particular reinforcement fabric, are fitted onto the beads, which have been softened by heating.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Kantenschutzrichtwinkels sowie einen Kantenschutzrichtwinkel mit einem insbesondere aus Kunststoff gefertigten Winkelprofil mit zwei aufeinander stehenden Schenkein, mit denen, deren Verlängerung bildend, Bewehrungsmatten verbunden sind, als Eckbewehrung für eine den Sichtputz tragende Mauerecke oder Wärmedämmschicht, wobei die Bewehrungsmatten durch Erhitzen des Winkelprofils an demselben festgelegt sind und die Randstreifen der Bewehrungsmatten über die äußeren Längsränder des Winkelprofils hinausragen.The invention relates to a method for producing an edge protection straightening bracket and an edge protection straightening bracket with an angle profile, in particular made of plastic, with two legs standing one on the other, with which, forming their extension, reinforcement mats are connected as corner reinforcement for a wall corner or thermal insulation layer carrying the plaster, the reinforcement mats are fixed to the same by heating the angle profile and the edge strips of the reinforcement mats protrude beyond the outer longitudinal edges of the angle profile.

Aus der DE-OS 26 41 585 ist ein Verfahren zur Herstellung einer Schutz-Führungsleiste für Mauerecken bekannt. Dabei wird in eine rinnenförmige Form, die der äußeren Körpergestaltung der Schutz-Führungsleiste entspricht, Preßkunststoff eingefüllt. Danach werden Netze an den verlängerten Innenflächen der Form in diese eingelegt und bei dem anschließenden Einfügen eines rechteckigen Stempels in den Kunststoff gedrückt. Durch Preßdruck und eventuelles Erhitzen der Leiste wird diese verfestigt und die Netze unverrückbar darin gehaltert. Nachteilig hieran ist, daß die Bewehrungsmatten eines derart hergestellten Kantenschutzrichtwinkels vollständig in dem Kunststoff des Winkelprofils eingebettet sind. Daher müssen Perforationen, durch die der Spachtelkleber hindurchtreten kann, nachträglich eingestanzt werden, was die Stabilität des Kantenschutzrichtwinkels schwächt. Auch können in der Putzschicht auftretende Kräfte, z.B. aufgrund von witterungs- und/oder tageszeitabhängig auftretenden Erwärmungen bzw. Abkühlungen der Sichtputzschicht, die besonders stark im Eckbereich des Sichtputzes auftreten, nicht über die in den Kunststoff eingebetteten Netze optimal aufgenommen und verteilt werden.From DE-OS 26 41 585 a method for producing a protective guide rail for wall corners is known. Pressed plastic is poured into a channel-like shape that corresponds to the outer body design of the protective guide strip. Then nets are inserted into the extended inner surfaces of the mold and then when a rectangular stamp is inserted into the Plastic pressed. By pressing pressure and possibly heating the bar, it is solidified and the nets immovably held in it. The disadvantage of this is that the reinforcement mats of an edge protection straightening angle produced in this way are completely embedded in the plastic of the angle profile. For this reason, perforations through which the filler adhesive can pass must be subsequently punched in, which weakens the stability of the edge protection straightening angle. Forces occurring in the plaster layer, e.g. due to the weather and / or daytime heating or cooling of the plaster layer, which occur particularly strongly in the corner area of the plaster, cannot be optimally absorbed and distributed via the nets embedded in the plastic.

Des weiteren sind Innenwinkel bekannt, auf die Glasfaserbewehrungsgewebe durch einen Schmelzkleber aufgeklebt werden. Auch hier sind die Bewehrungsgewebe über ihre gesamte Anlagefläche mit dem Innenwinkel verbunden. Durch thermische Dimensionsänderung des Kunststoff-Innenwinkels können Spannungen in der Klebeverbindung und dem Bewehrungsgewebe auftreten.Inner angles are also known, onto which glass fiber reinforcement fabrics are glued using a hot-melt adhesive. Here too, the reinforcement mesh is connected to the interior angle over its entire contact surface. Due to thermal dimensional changes of the plastic inner angle, tensions can occur in the adhesive connection and the reinforcement mesh.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Kantenschutzrichtwinkels sowie einen Kantenschutzrichtwinkel zu schaffen, der einfach hergestellt werden kann, gegenüber thermischen Längenänderungen unempfindlich ist und eine erhöhte Stabilität, insbesondere Formstabilität, aufweist.The invention is therefore based on the object of providing a method for producing an edge protection straightening angle and an edge protection straightening angle which can be easily produced, is insensitive to thermal changes in length and has increased stability, in particular dimensional stability.

Erfindungsgemäß wird die genannte Aufgabe bei einem Verfahren der eingangs genannten Art dadurch gelöst, daß das mittels Extrudieren gefertigte Winkelprofil mit mindestens einem Wulst auf jedem seiner Schenkel versehen wird und auf die durch Erhitzen aufgeweichten Wülste die Bewehrungsmatten, insbesondere Bewehrungsgewebe aufgebracht werden. Danach werden sie in die Wülste eingepreßt und die Wülste und die Bewehrungsgewebe miteinander verwalzt. Ein erfindungsgemäßer Kantenschutzrichtwinkel zeichnet sich dadurch aus, daß das Winkelprofil auf jedem seiner Schenkel mindestens einen Wulst aufweist, wobei die Bewehrungsmatten, insbesondere Bewehrungsgewebe, an den Wülsten des Winkelprofils festgelegt, insbesondere befestigt sind. Das Befestigen erfolgt bevorzugt durch Einpressen und Verwalzen.According to the invention, the stated object is achieved in a method of the type mentioned at the outset in that the angle profile produced by extrusion has at least a bead is provided on each of its legs and the reinforcement mats, in particular reinforcement mesh, are applied to the beads softened by heating. Then they are pressed into the beads and the beads and the reinforcement mesh are rolled together. An edge protection straightening angle according to the invention is characterized in that the angle profile has at least one bead on each of its legs, the reinforcement mats, in particular reinforcement mesh, being fixed, in particular fastened, to the beads of the angle profile. The attachment is preferably carried out by pressing and rolling.

Hierdurch wird ein Kantenschutzrichtwinkel geschaffen, bei dem die Bewehrungsgewebe lediglich über die Wülste mit dem Winkelprofil verbunden sind. Das Bewehrungsgewebe wird auf diese Weise zum einen unverrückbar mit dem Winkelprofil verbunden, zum anderen können z.B. durch thermische Längenänderungen auftretende Kräfte auch im Bereich des Winkelprofils aufgenommen und über das Bewehrungsgewebe verteilt werden. Dadurch, daß das Winkelprofil erhitzt wird, ist die Verwendung von Sprühklebern, die vielfach in manuellen Arbeitsgängen auf das Winkelprofil aufgebracht werden, nicht mehr notwendig. Dadurch, daß die Wülste und die Bewehrungsgewebe miteinander verwalzt werden, ist dafür gesorgt, daß beim fertigen Kantenschutzrichtwinkel keine durch die Wülste verursachten Vorsprünge mehr vorhanden sind, wodurch die Dicke des Kantenschutzrichtwinkels vergrößert wäre.This creates an edge protection straightening angle in which the reinforcement fabrics are connected to the angle profile only via the beads. In this way, the reinforcement mesh is immovably connected to the angle profile, on the other hand, e.g. forces occurring due to thermal changes in length can also be absorbed in the area of the angle profile and distributed over the reinforcement mesh. Because the angle profile is heated, the use of spray adhesives, which are often applied to the angle profile in manual operations, is no longer necessary. The fact that the beads and the reinforcement mesh are rolled together ensures that the projections caused by the beads are no longer present in the finished edge protection straightening bracket, which would increase the thickness of the edge protection straightening bracket.

Erfindungsgemäß ist bei einer Ausführungsform vorgesehen, daß das Winkelprofil beim Extrudieren mit mindestens einem Wulst auf jedem seiner Schenkel versehen wird und daß die Erhitzung der Wülste nach dem Einstanzen von Löchern auf den Schenkein des Winkelprofils erfolgt, wobei die Löcher über und unter bzw. rechts und links der Wülste eingestanzt werden. Bei einer zweiten Ausführungsform ist erfindungsgemäß vorgesehen, daß das Winkelprofil nach dem Extrudieren mit mindestens einem Wulst auf jedem seiner Schenkel versehen wird. Das Auftragen der Wülste erfolgt durch ein Kunststoffschweißgerät. Um die Wülste und das ausgehärtete Winkelprofil miteinander zu verbinden, wird letzteres vor Auftragen der Wülste erhitzt. Hierdurch wird ein Hindurchtreten von Spachtelmaterial nach außen ermöglicht, wodurch im erhärteten Zustand eine besonders gute Fixierung des Winkelprofils auf der Eckkante der zu bewehrenden Mauer erzielt wird. Da bei der ersten Ausführungsart das Einstanzen der Löcher vor dem Erhitzen der Wülste erfolgt und die Wülste durch diesen Einstanzvorgang nicht beschädigt werden, kann das Bewehrungsgewebe ohne Ausstanzungen formschlüssig am Winkelprofil anhaften, wobei aber gleichzeitig genügend Spachtelkleber durch die Maschen des Bewehrungsgewebes sowie die Löcher hindurchtreten kann. Gleiches gilt auch für die zweite Ausführungsart, da hier ja erst das Lochen und danach das Auftragen der Wülste erfolgt. Da das Bewehrungsgewebe durch ein nachträgliches Lochen des Winkelprofils nicht beschädigt wird, ist auch für eine hohe Stabilität des derart gefertigten Kantenschutzrichtwinkels gesorgt.According to the invention it is provided in one embodiment that the angle profile during extrusion is provided with at least one bead on each of its legs and that the beads are heated after the holes have been punched the legs of the angle profile are made, the holes being punched above and below or to the right and left of the beads. In a second embodiment it is provided according to the invention that after extrusion the angle profile is provided with at least one bead on each of its legs. The beads are applied using a plastic welding device. In order to connect the beads and the hardened angle profile, the latter is heated before the beads are applied. This allows the filler material to pass through to the outside, which in the hardened state achieves particularly good fixation of the angle profile on the corner edge of the wall to be reinforced. Since in the first embodiment the holes are punched before the beads are heated and the beads are not damaged by this punching process, the reinforcement mesh can adhere positively to the angle profile without punching out, but at the same time sufficient filler adhesive can pass through the meshes of the reinforcement mesh and the holes . The same also applies to the second embodiment, since here the holes are punched and then the beads are applied. Since the reinforcement mesh is not damaged by subsequent perforation of the angle profile, the edge protection straightening angle produced in this way is also highly stable.

Weiterbildungen sehen vor, daß jeder der Wülste der ersten Ausführungsart entweder durchgehend oder aber punktuell erhitzt und damit erweicht wird, wobei letzteres für die Stabilität des herzustellenden Kantenschutzrichtwinkels ausreichend ist.Further developments provide that each of the beads of the first embodiment is heated either continuously or selectively and is thus softened, the latter being sufficient for the stability of the edge protection straightening angle to be produced.

Das Erhitzen und Aufweichen der Wülste erfolgt bevorzugt mittels eines Lasers oder eines Kunststoffschweißgerätes.The beads are preferably heated and softened by means of a laser or a plastic welding device.

Auf diese Weise wird eine gezielte Aufweichung lediglich der Wülste ermöglicht. Auch ein gezieltes punktuelles Erhitzen der Wülste ist bei der Verwendung eines Lasers auf einfache Weise möglich, da hierdurch eine gezielte Oberflächen-Erwärmung durchgeführt werden kann. Das Verfahren ist aber nicht auf die Verwendung eines Lasers oder eines Kunststoffschweißgerätes beschränkt. Es kann jede geeignete Art von Heizquelle zur gezielten Oberflächen-Erwärmung herangezogen werden.In this way, a targeted softening of only the beads is made possible. Targeted, selective heating of the beads is also possible in a simple manner when using a laser, since this enables targeted surface heating. However, the method is not limited to the use of a laser or a plastic welding device. Any suitable type of heating source can be used for targeted surface heating.

Weiterbildungen des erfindungsgemäßen Kantenschutzrichtwinkels sehen vor, daß die Wülste geradlinig, im wesentlichen parallel zu den Längsrändern des jeweiligen Schenkels auf den jeweiligen Schenkeln angeordnet sind. Die Wülste können auch eine wellenförmige bzw. zickzackförmige Ausbildung auf den jeweiligen Schenkeln aufweisen. Die Löcher sind dabei ober- und unterhalb bzw. rechts und links der Wülste angeordnet. Auf diese Weise wird eine optimale Ausnutzung der durch das Winkelprofil zur Verfügung stehenden Anlagefläche und Verbindungsfläche für die Bewehrungsgewebe sowie die Einstanzungen ermöglicht. Die durch die Perforation bedingte Schwächung des Kantenschutzrichtwinkels bleibt minimal. Die Bewehrungsgewebe können optimal am Winkelprofil festgelegt werden, es verbleibt aber genügend Raum, um die auftretenden Kräfte über die Bewehrungsgewebe zu verteilen.Further developments of the edge protection straightening angle according to the invention provide that the beads are arranged in a straight line, essentially parallel to the longitudinal edges of the respective leg on the respective legs. The beads can also have an undulating or zigzag-shaped design on the respective legs. The holes are arranged above and below or on the right and left of the beads. In this way, an optimal utilization of the contact surface and connection surface available for the reinforcement mesh as well as the punchings is made possible by the angle profile. The weakening of the edge protection straightening angle caused by the perforation remains minimal. The reinforcement mesh can be optimally fixed on the angle profile, but there is enough space to distribute the forces that occur over the reinforcement mesh.

Während die durch die aufeinander stehenden Schenkel des Winkelprofils gebildete Winkelspitze glatt ausgebildet sein kann, ist in bevorzugter Weiterbildung vorgesehen, daß sie mit einem Vorsprung versehen ist. Ein derartiger Vorsprung eignet sich als Abzugskante für die auf den Kantenschutzrichtwinkel sowie die Bewehrungsmatten aufzubringende Putzschicht. Bei der erfindungsgemäßen Ausbildung mit einer Abzugskante wird verhindert, daß an den Eckkanten der zu bewehrenden Mauer bzw. Wärmedämmschicht nach Auftragen des Sichtputzes dieser an den Kanten übersteht.While the angular tip formed by the legs of the angular profile standing on top of one another can be smooth, in a preferred development it is provided that it is provided with a projection. Such a projection is suitable as a pull-off edge for the plaster layer to be applied to the edge protection straightening angle and the reinforcement mats. In the training according to the invention With a pull-off edge it is prevented that on the corner edges of the wall or thermal insulation layer to be reinforced after application of the visual plaster it protrudes on the edges.

Weitere Vorteile und Merkmale ergeben sich aus den Ansprüchen sowie aus der nachfolgenden Beschreibung, in der Ausführungsbeispiele des durch das erfindungsgemäße Verfahren hergestellten Kantenschutzrichtwinkels unter Bezugnahme auf die Zeichnungen im einzelnen erläutert sind. Dabei zeigt:

In Figur 1 ist ein Winkelprofil 2 eines in Figur 6 und 7 dargestellten Kantenschutzrichtwinkels 1 dargestellt. Das Winkelprofil 2 ist aus einem Kunststoff, z.B. PVC oder PP, gefertigt. Es weist zwei Schenkel 3, 4 auf, die rechtwinklig zueinander verlaufend eine Winkelspitze 5 ausbilden. In jeden Schenkel 3, 4 des Winkelprofils 2 sind jeweils Löcher 6 eingestanzt, zwischen denen in dem in Figur 1 dargestellten Ausführungsbeispiel geradlinig verlaufende Wülste 7 ausgebildet sind. Dabei kann ein Schenkel 4 entweder mit nur einem Wulst 7 oder aber ein Schenkel 3 mit zwei Wülsten 7 versehen sein. Die Wülste weisen eine Dicke zwischen 0,01 mm und 5 mm auf.FIG. 1 shows an angle profile 2 of an edge protection straightening angle 1 shown in FIGS. 6 and 7. The angle profile 2 is made of a plastic, e.g. PVC or PP, manufactured. It has two legs 3, 4, which form an angular tip 5 extending at right angles to one another. Holes 6 are punched into each leg 3, 4 of the angle profile 2, between which straight beads 7 are formed in the exemplary embodiment shown in FIG. A leg 4 can either be provided with only one bead 7 or a leg 3 with two beads 7. The beads have a thickness between 0.01 mm and 5 mm.

Im in Figur 2 dargestellten Ausführungsbeispiel sind die Schenkel 3, 4 des Winkelprofils 2 mit jeweils wellenförmig verlaufenden Wülsten 8 versehen. Auch hier sind die Löcher 6 rechts und links der Wülste 8 angeordnet.In the embodiment shown in Figure 2, the legs 3, 4 of the angle profile 2 are each provided with undulating beads 8. Here, too, the holes 6 are arranged on the right and left of the beads 8.

In Figur 3 ist lediglich ein wellenförmig verlaufender Wulst 8 des Winkelprofils 2 aus Figur 2 dargestellt. Der Wulst 8 ist dabei, wie aus der Zeichnung ersichtlich ist, lediglich punktuell (schraffiert gezeichnet und mit Bezugszeichen 9 versehen) erhitzt und aufgeweicht. Auf diese Weise ist ein an dem Wulst 8 zu befestigendes Bewehrungsgewebe ungleichmäßig oder gleichmäßig über den Schenkel 4 verteilt über diesen Wulst 8 mit dem Winkelprofil 2 verbindbar.In Figure 3, only a wavy bead 8 of the angle profile 2 from Figure 2 is shown. The bead 8 is, as can be seen from the drawing, only heated and softened at certain points (hatched and provided with reference number 9). In this way, a reinforcement fabric to be fastened to the bead 8 can be connected to the angle profile 2 in an uneven or uniform manner distributed over the leg 4 via this bead 8.

In Figur 4 ist das Winkelprofil mit glatt ausgebildeter Winkelspitze 5 dargestellt. In Figur 5 weist das Winkelprofil 2 einen Vorsprung 10 an der Winkelspitze auf. Die durch den Vorsprung 10 gebildete Auswölbung an der Winkelspitze ist als Abzugskante beim Aufbringen der Putzschicht dienlich. Es wird für einen geradlinigen Verlauf der Sichtputzkante gesorgt, da der Sichtputz an der Winkelspitze nach Aufbringen desselben nicht den jeweiligen Schenkel 3 oder 4 des Winkelprofils 2 überragt.FIG. 4 shows the angle profile with a smoothly formed angle tip 5. In Figure 5, the angle profile 2 has a projection 10 at the angle tip. The bulge formed by the projection 10 at the angle tip is useful as a pull-off edge when applying the plaster layer. A straight line of the exposed plaster edge is ensured since the exposed plaster at the angled tip does not protrude beyond the respective leg 3 or 4 of the angled profile 2 after it has been applied.

Wie aus den Figuren 6 und 7 ersichtlich ist, ist beim erfindungsgemäßen Kantenschutzrichtwinkel 1 an der Außenseite des Winkelprofils 2 ein Bewehrungsgewebe 11 befestigt. Das Bewehrungsgewebe 11 ist dabei unmittelbar am Winkelprofil 2 anliegend angeordnet und mittels des erfindungsgemäßen Verfahrens über die hier nicht dargestellten Wülste an dem Winkelprofil 2 festgelegt. Das an der Außenseite des Winkelprofils 2 angeordnete Bewehrungsgewebe 11 ragt mit seinen Randstreifen 12 über die äußeren Längskanten 13, 14 des aus Kunststoff bestehenden Winkelprofils 2 hinaus. Wie außerdem aus den Figuren 6 und 7 ersichtlich ist, ist der aus Bewehrungsgewebe 11 und Winkelprofil 2 gebildete Kantenschutzrichtwinkel 1 nicht durchgehend mit Löchern 6 versehen. Vielmehr werden diese Löcher 6 an der Außenseite des Winkelprofils 2 von den sich kreuzenden Schuß- und Kettfäden 15, 16 überdeckt. Dabei verbleibt genügend lichter Raum für das Hindurchtreten der Spachtelmasse. Über die über die Längskanten 13, 14 hinausragenden Randstreifen 12 ist der Kantenschutzrichtwinkel 1 mit zur Bewehrung einer Spachtelmaterialschicht dienenden Glasfaser-GFK-Gewebematten verbindbar.As can be seen from FIGS. 6 and 7, in the edge protection straightening bracket 1 according to the invention, a reinforcement mesh 11 is attached to the outside of the angle section 2. The reinforcement mesh 11 is arranged directly adjacent to the angle profile 2 and is fixed to the angle profile 2 by means of the method according to the invention via the beads not shown here. The reinforcement fabric 11 arranged on the outside of the angle profile 2 projects with its edge strips 12 beyond the outer longitudinal edges 13, 14 of the angle profile 2 made of plastic. As can also be seen from FIGS. 6 and 7, the edge protection straightening angle 1 formed from reinforcement mesh 11 and angle profile 2 is not provided with holes 6 throughout. Rather, these holes 6 on the outside of the angle profile 2 are covered by the crossing weft and warp threads 15, 16. This leaves enough clear space for the filler to pass through. Via the edge strips 12 projecting beyond the longitudinal edges 13, 14, the edge protection straightening angle 1 can be connected to glass fiber-GFK fabric mats used to reinforce a filler material layer.

Die Herstellung des beschriebenen Kantenschutzrichtwinkels 1 erfolgt folgendermaßen:The described edge protection straightening angle 1 is produced as follows:

Zunächst wird mittels eines Extruders ein Winkelprofil aus Kunststoff, z.B. PVC oder PP, hergestellt und dabei bei der ersten Ausführungsart mit zumindest einem 0,01-5,0 mm dicken Wulst auf jedem Schenkel des Winkelprofils versehen. Nach dem Extrudieren werden auf den Schenkeln jeweils über und unter bzw. rechts und links neben den Wülsten Löcher eingestanzt. Diese Löcher sind vorgesehen, damit im Bereich des Winkelprofils Öffnungen vorhanden sind, durch die beim Aufbringen auf Wärmedämmplatten Spachtelkleber hindurchtreten kann, der sich dann mit den Wärmedämmplatten verbindet. Nach dem Ausstanzen der Löcher werden die auf den Schenkeln befindlichen Wülste durch einen Laserstrahl entweder auf ihrer ganzen Länge oder aber punktuell erwärmt und damit aufgeweicht. Das Aufweichen kann auch mittels eines Kunststoffschweißgerätes erfolgen. Unmittelbar im Anschluß hieran wird das Bewehrungsgewebe aufgebracht, in den nunmehr durch die Oberflächenerwärmung aufgeweichten Wulst eingepreßt und hiermit verwalzt. Das Erhitzen der Wülste kann auch durch jede für die punktuelle Oberflächenerwärmung geeignete Art von Heizquelle erfolgen.First an angle profile made of plastic, e.g. PVC or PP, manufactured and provided in the first embodiment with at least one 0.01-5.0 mm thick bead on each leg of the angle profile. After extrusion, holes are punched on the legs above and below or to the right and left of the beads. These holes are provided so that there are openings in the area of the angle profile through which, when applied to thermal insulation boards, filler adhesive can pass through, which then connects to the thermal insulation boards. After the holes have been punched out, the beads on the legs are heated by a laser beam either over their entire length or selectively and thus softened. The softening can also be done by means of a plastic welding device. Immediately afterwards, the reinforcement fabric is applied, pressed into the bead, which has now been softened by the surface heating, and rolled with it. The beads can also be heated by any type of heating source that is suitable for selective surface heating.

Bei der zweiten Ausführungsart wird mittels eines Extruders lediglich das Winkelprofil ohne Wülste aus Kunststoff, z.B. PVC oder PP, hergestellt. Nach dem Aushärten des Winkelprofils erfolgt das Einstanzen der Löcher. Danach wird die Oberfläche der Winkelprofilaußenseiten durch ein einem Kunststoffschweißgerät vorgeschaltetes Erhitzungsgerät aufgeweicht. Die Wülste werden dann durch das Kunststoffschweißgerät zwischen den eingestanzten Löchern aufgetragen und verbinden sich mit der erwärmten Winkelprofilaußenseite. Unmittelbar daran erfolgt das Aufbringen der Bewehrungsgewebe entsprechend der ersten Ausführungsart.In the second embodiment, only the angle profile without beads made of plastic, for example PVC or PP, is produced using an extruder. After the angle profile has hardened, the holes are punched. The surface of the outside of the angle profile is then softened by a heating device connected upstream of a plastic welding device. The beads are then punched between the plastic welding machine Holes are applied and connect to the heated angle profile outside. Immediately afterwards, the reinforcement mesh is applied in accordance with the first embodiment.

Ein mittels dieser Verfahren gefertigter Kantenschutzrichtwinkel dient bevorzugt als Träger für die auf das Vollwärmeschutzsystem aufgebrachte Außenputzschicht, so daß diese zuverlässig auf den Außenwänden bzw. einem aufgebrachten Wärmedämmantel haftet. Die Eckkanten der auf die Außenwände aufgebrachten Wärmedämmplatten, deren Anordnung auch die Eckkante des Sichtputzes bestimmt ist, sind durch den Kantenschutzrichtwinkel vor Beschädigung geschützt, sobald der Spachtelkleber und der Sichtputz aufgebracht sind. Auch dann, wenn es beim Transport oder der Verarbeitung der Wärmedämmplatten etc. zu Beschädigungen der Eckkante gekommen ist, wird durch das Anbringen des durch das erfindungsgemäße Verfahren hergestellten erfindungsgemäßen Kantenschutzrichtwinkels ein geradliniger Verlauf der Sichtputzschichtkante gewährleistet.An edge protection straightening bracket produced by means of this method preferably serves as a carrier for the outer plaster layer applied to the full heat protection system, so that it adheres reliably to the outer walls or to an applied thermal insulation jacket. The corner edges of the thermal insulation panels applied to the outer walls, the arrangement of which also determines the corner edge of the exposed plaster, are protected from damage by the protective edge angle as soon as the filler adhesive and the exposed plaster are applied. Even if there is damage to the corner edge during transport or processing of the thermal insulation boards, the application of the edge protection straightening angle according to the invention produced by the method according to the invention ensures a straight course of the visible plaster layer edge.

Ein derartig gefertigter Kantenschutzrichtwinkel ist aber nicht nur als Träger für die Außenputzschicht, sondern auch als ein solcher für die Innenputzschicht bezüglich der Sichtkante verwendbar.Such an edge protection straightening angle can be used not only as a carrier for the outer plaster layer, but also as such for the inner plaster layer with respect to the visible edge.
