Abstract

PCT No. PCT/EP88/01074 Sec. 371 Date Jul. 24, 1990 Sec. 102(e) Date Jul. 24, 1990 PCT Filed Nov. 25, 1988 PCT Pub. No. WO89/04897 PCT Pub. Date Jun. 1, 1989.A protective lath for protection againt dirt and damage during wall plastering and against penetration of moisture at the joint to building components of different material, such as wood, plastics or metal, in particular to window and door frames or rafter ends, on which the plaster abuts; the protective lath is made of hard synthetic resin injected by an extruder into a continuous flow mold and carries a strip for adhering it to such a building component as well as a lateral protective tab which can be broken off by hand via a notch-type incision; a top part also made of hard synthetic resin is pressed onto a bottom part of the protective lath which carries said adhesive strip, with a reinforcing fabric, e.g. of synthetic resin coated silk glass, that extends as far as possible into the plaster layer, being interposed between said parts, and the free end of the top part being resiliently latched in an undercut nose piece of a side wall of the bottom part.

Description

Die Erfindung bezieht sich auf eine Schutzleiste für die Herstellung eines Putzanschlusses beim Mauerputzvorgang an ein Bauteil aus anderem Material. Dieses Bauteil besteht beispielsweise aus Holz, Kunststoff oder Metall Bei diesem Bauteil handelt es sich vorzugsweise um Fensterrahmen, Türrahmen oder Sparrenköpfe.The invention relates to a protective strip for the production of a plaster connection during the wall plastering process to a component made of a different material. This component consists, for example, of wood, plastic or metal. This component is preferably window frames, door frames or rafters.

Traditionell hat man den Mauerputz direkt bis an das Bauteil herangeputzt, was zu erheblicher Verschmutzung des Bauteils geführt hat und nicht zu einer dauerhaften und dichten Verbindung zwischen dem Mauerputz und dem Bauteil geführt hat.Traditionally, the wall plaster has been plastered right up to the component, which has led to considerable contamination of the component and has not led to a permanent and tight connection between the wall plaster and the component.

Aus dem DE-GM-82 25 357 ist eine Schutzleiste aus Metall bekannt, die an das Bauteil angeklebt wird. An der Schutzleiste ist der Rand eines Armierungsgewebes angeklebt, das beim Mauerputzvorgang in die Putzschicht eingebettet wird Dabei wird nach wie vor der Oberputz über die Metallschiene und das darunterliegende Klebeband unmittelbar bis an das Bauteil herangeputzt, wodurch im dortigen Bereich keine feste Verbindung zu dem Bauteil besteht. Damit ist das Problem des aus der Praxis bekannten sog Abrisses ungelöst, da sich die von solchen Bauteilen ausgehenden Erschütterungen direkt auf den Oberputz übertragen Ferner wird das Armierungsgewebe dort seitlich aus der Verbindung zwischen der Metallschiene und dem Klebeband herausgeführt, so daß dessen Einbettung in die je nach Herstellervorschrift unterschiedlich dicke Spachtelmassenschicht nicht genügend variabel durchgeführt werden kann. Außerdem gibt es keinen Schutz gegen Verschmutzung oder Beschädigung des Bauteils.From DE-GM-82 25 357 a protective strip made of metal is known, which is glued to the component. The edge of a reinforcing fabric is glued to the protective strip, which is embedded in the plaster layer during the wall plastering process.As before, the top plaster is plastered over the metal rail and the underlying adhesive tape directly to the component, so that there is no fixed connection to the component in the area . This solves the problem of the so-called demolition known in practice, since the vibrations emanating from such components are transferred directly to the finishing coat. Furthermore, the reinforcing fabric is led out laterally from the connection between the metal rail and the adhesive tape, so that its embedding in each according to the manufacturer's instructions, it is not possible to carry out a sufficiently variable leveling compound layer. In addition, there is no protection against dirt or damage of the component.

Aus dem DE-GM 86 11 867 ist eine Schutzleiste aus Kunststoff bekannt, die aufgrund ihrer Gestalt und Breite einen Schutz gegen Verschmutzung oder Beschädigung des Bauteils bietet. Diese Schutzleiste weist jedoch kein Armierungsgewebe auf.A protective strip made of plastic is known from DE-GM 86 11 867, which, due to its shape and width, offers protection against soiling or damage to the component. However, this protective strip has no reinforcement fabric.

Gegenstand der Erfindung ist eine Schutzleiste für die Herstellung eines Putzanschlusses an ein Bauteil aus anderem Material, insbesondere an einen Fenster- oder Türrahmen, mit folgenden Merkmalen:

  • a) die Schutzleiste weist ein Unterteil aus Kunststoff und ein Oberteil aus Kunststoff auf;
  • b)das Unterteil ist mit einem Klebeband zum Ankleben an das Bauteil versehen;
  • c) zwischen dem Unterteil und dem Oberteil ist ein Armierungsgewebe zur Einbettung in den anschließenden Putz festgeklemmt;
  • d) das Unterteil ist mit dem Oberteil formschlüssig federnd verrastet;
  • e) die Schutzleiste weist eine seitliche Schutzlasche zum Schützen des Bauteils auf, die über einen Kerbeinschnitt von Hand abbrechbar ist.
The invention relates to a protective strip for the production of a plaster connection to a component made of a different material, in particular to a window or door frame, with the following features:
  • a) the protective strip has a lower part made of plastic and an upper part made of plastic;
  • b) the lower part is provided with an adhesive tape for sticking to the component;
  • c) a reinforcing fabric for embedding in the subsequent plaster is clamped between the lower part and the upper part;
  • d) the lower part is positively locked with the upper part;
  • e) the protective strip has a lateral protective flap for protecting the component, which can be broken off by hand via a notch cut.

Bei der erfindungsgemäßen Schutzleiste ist jeglicher Kontakt von Putzmaterialien mit dem anderen Bauteil unterbunden. Die von diesem Bauteil ausgehenden Erschütterungen werden sicher von dem Putzauftrag ferngehalten und können sich nicht dorthin übertragen. Nach Abschluß des Mauerputzvorgangs bildet der dann noch einzig sichtbare Kunstharz der Schutzleiste, die Abziehkante, eine saubere Begrenzung des Leibungsputzes, die auch späterhin eine leichte und bessere Pflege der Fenster- oder Türrahmen ermöglicht.In the protective strip according to the invention, any contact of cleaning materials with the other component is prevented. The vibrations emanating from this component are safely kept away from the plaster application and cannot be transferred there. After completing the wall plastering process, the only visible synthetic resin of the protective strip, the peeling edge, forms a clean boundary of the reveal plaster, which also later allows easy and better maintenance of the window or door frames.

Besonders günstig läßt sich die erfindungsgemäße Schutzleiste einsetzen, wenn die an das Bauteil anschließende Wand mit einem mineralischen oder organischen Vollwärmeschutzsystem versehen ist. Bei diesen Systemen ist häufig das Armierungsgewebe wünschenswert, um die Verankerung der Putzschicht auf der Wärmeisolationsschicht sicherzustellen. Im Bereich des Anschlusses der Putzschicht an das andere Bauteil ist das Eindringen von Feuchtigkeit ausgeschlossen. Das Unterteil und das Oberteil der Schutzleiste sind vorzugsweise aus hartem Kunstharz über einen Extruder in eine Durchlaufform gespritzt. Die Schutzlasche hat vorzugsweise ein T-förmiges Profil. Das Armierungsgewebe besteht vorzugsweise aus kunstharzummanteltem Seidenglas. Auf der Schutzlasche ist vorzugsweise auf der dem Bauteil abgewandten Seite ein Klebeband vorgesehen, so daß dort eine Schutzfolie für die Fensteröffnung oder die Türöffnung aufgeklebt werden kann. Das Armierungsgewebe bewirkt, daß der Putz beim Schwinden weder in seinem Inneren noch zur Schutzleiste hin Risse bekommt und undicht wird.The protective strip according to the invention can be used particularly inexpensively if the wall adjoining the component is provided with a mineral or organic full heat protection system. In these systems, the reinforcement fabric is often desirable in order to ensure that the plaster layer is anchored on the heat insulation layer. The penetration of moisture is excluded in the area of the connection of the plaster layer to the other component. The lower part and the upper part of the protective strip are preferably injection molded from hard synthetic resin into a continuous mold via an extruder. The protective tab preferably has a T-shaped profile. The reinforcement fabric is preferably made of synthetic resin-coated silk glass. An adhesive tape is preferably provided on the protective tab on the side facing away from the component, so that a protective film for the window opening or the door opening can be glued there. The reinforcing fabric ensures that the plaster does not crack or leak when it is shrinking, neither inside nor towards the protective strip.

Anspruch 2 beschreibt ein erstes Ausführungsbeispiel, bei dem die Einraststelle dem Mauerwerk zugewandt ist und das andere Ende des ebenfalls aus hartem Kunstharz bestehenden Oberteils unter Zwischenlage des Armierungsgewebes in eine hinterschnittene Seitenwand des Unterteils eingreift.Claim 2 describes a first embodiment in which the latching point faces the masonry and the other end of the upper part, which is also made of hard synthetic resin, engages in an undercut side wall of the lower part with the interposition of the reinforcing fabric.

Nach Anspruch 3 fluchten dabei die der Putzschicht zugewandten Oberflächen von Ober- und Unterteil im angedrückten und eingerasteten Zustand wenigstens näherungsweise. Zum Erleichtern des Einrastens ist nach Anspruch 4 das Nasenstück etwa halbkreisförmig abgerundet und das dazugehörige Ende des Oberteils oben entsprechend eingeschnitten Anspruch 5 beschreibt ein zweites Ausführungsbeispiel, nach dem das Oberteil in das Unterteil von etwa gleicher Wandstärke übergeht, das über ein Verbindungsstück von verminderte Wandstärke umklappt und unter Zwischenlage des Armierungsgewebes angedrückt wird und mit einem freien Ende in das hinterschnittene Nasenstück der dem Mauerwerk abgewandten Seitenwand federnd einrastet.According to claim 3, the surfaces of the upper and lower parts facing the plaster layer are at least approximately aligned in the pressed and latched state. To facilitate snapping, the nose piece is rounded approximately semicircularly according to claim 4 and the corresponding end of the upper part is cut accordingly at the top Claim 5 describes a second embodiment, according to which the upper part merges into the lower part of approximately the same wall thickness, which folds over a connecting piece of reduced wall thickness and is pressed in with the interposition of the reinforcing fabric and resiliently with a free end in the undercut nose piece of the side wall facing away from the masonry snaps into place.

Die Ansprüche 6 und 7 geben für beide Ausführungsbeispiele an, auf welche Weise das Oberteil unter Zwischenlage des Armierungsgewebes an das Unterteil vorteilhaft angedrückt wird.For both exemplary embodiments, claims 6 and 7 indicate the manner in which the upper part is advantageously pressed onto the lower part with the reinforcing fabric being interposed.

Die im Anspruch 8 angeführte Faserplatte, die nach Anspruch 9 zusammen mit dem herausragenden Teil des Armierungsgewebes in eine Spachtelmassenschicht eingebettet ist, hat Wärmedämmungsfunktion.The fibreboard mentioned in claim 8, which according to claim 9 is embedded together with the protruding part of the reinforcing fabric in a filler layer, has a heat insulation function.

Besondere Putzarten, insbesonder solcher mineralischer Art, erfordern eine breite Auflagefläche an der dem Mauerwerk abgewandten Seitenwand; zur Ersparnis von teurem Kunstharzwerkstoff und somit auch zur Schonung von Rohstoffen, wird dann nach Anspruch 10 eine inne Aussparung vorgesehen.Special types of plaster, in particular of such a mineral type, require a wide contact surface on the side wall facing away from the masonry; To save expensive synthetic resin material and thus also to protect raw materials, an internal recess is then provided according to claim 10.

Nach Anspruch 11 dient die Außenseite der dem Mauerwerk abgewandten Seitenwand der Schutzleiste in bekannter Weise als Abziehkante für den Oberputz; diese Außenseite ist zugleich Begrenzungsschutz beim Säubern der Fenster- und Türrahmen.According to claim 11, the outside of the masonry side wall of the protective strip is used in a known manner as a peeling edge for the finishing coat; this outside is at the same time limiting protection when cleaning the window and door frames.

Nach Anspruch 12 soll die Vorderseite der dem Mauerwerk abgewandten Außenwand mit Dreiecks-Höckern ausgebildet sein. Diese Außenwand ist der Bewitterung ausgesetzt und an deren Vorderseite schließt der Putz an. Durch die Dreiecks-Höcker wird eine Verzahnung mit dem Putz herbeigeführt.According to claim 12, the front of the masonry facing outer wall should be formed with triangular bumps. This outer wall is exposed to weathering and the plaster connects to the front. The triangular humps are used to interlock with the plaster.

Nach Anspruch 13 soll die Schutzlasche einen nach innen gerichteten Steg von solcher Höhe tragen, welche der Stärke des weichen Klebebandes entspricht, damit Schutzleiste und Schutzlasche in einer Ebene liegen, wenn die Schutzfolie angebracht wird.According to claim 13, the protective tab should carry an inwardly directed web of a height which corresponds to the thickness of the soft adhesive tape, so that the protective strip and protective tab lie in one plane when the protective film is attached.

Die in den Ansprüchen 14 bis 16 angeführten Merkmale bezüglich des zum Befestigen der Schutzleiste dienenden weichen Bands sollen davor schützen, daß sich diese durch die permanent auftretenden Erschütterugen vom Putz löst.The features cited in claims 14 to 16 with regard to the soft strip used to fasten the protective strip are intended to protect it from being detached from the plaster by the constantly occurring vibrations.

Die Erfindung wird anhand einer Querschnittszeichnung mit zwei Ausführungsbeispielen näher erläutert; dabei zeigt

  • Figur 1 - die zu schützende Vorrichtung mit dem in dem Unterteil eingedrückten Oberteil,
  • Figur 2 - mit einem über das Unterteil umgeklappten Oberteil und zwar jeweils mit breiter Auflagefläche für die Faserplatte und den Putz, mit der in diesem Teil inneren Aussparung,
  • Figur 2a - dagegen mit schmaler Auflagefläche für den Putz und ohne die innere Aussparung
The invention is explained in more detail using a cross-sectional drawing with two exemplary embodiments; shows
  • Figure 1 - the device to be protected with the upper part pressed into the lower part,
  • Figure 2 - with an upper part folded over the lower part, each with a wide contact surface for the fiberboard and the plaster, with the inner recess in this part,
  • Figure 2a - on the other hand with a narrow support surface for the plaster and without the inner recess

Nach Figur 1 ist eine Schutzleiste (1) aus hartem Kunstharz mittels eines gleich breiten und langen Bands (2) mit beidseitiger Klebeschicht (2a) aus geschäumten, also weichem Kunstharz an einem Fensteroder Türrahmen (3) befestigt und zusammen mit diesem mit seitlichem Abstand A, der mit Kontaktschaum oder Isolierwolle (10) ausgefüllt ist, im Mauerwerk (5) gelagert. Dichtheit des Mauerputzes gegen von außen her ankommende Feuchtigkeit wird dadurch erreicht, daß an das jenes Klebeband tragende Unterteil (1d) der Schutzleiste (1) unter Zwischenlage eines bin in die Putzschicht (6, 6a) hineinreichenden Armierungsgewebes (8) aus kunstharzummanteltem Seidenglas ein ebenfalls aus hartem Kunstharz bestehendes Oberteil (1b) angedrückt ist, das mit einem Ende (1b′) in ein hinterschnittenes Nasenstück (1a˝) von Halbkreisform der dem Mauerwerk zugewandten Seitenwand (1a) des Unterteils (1d) federnd eingerastet ist. Das andere Ende (1b˝) des Oberteils greift unter Zwischenlage des von hier aus in die Putzschicht eindringenden Armierungsgewebes in eine hinterschnittene Seitenwand (1c) des Unterteils ein. In diesem angedrückten und eingerastetem Zustand fluchten die der Putzschicht zugewandten Oberflächen von Ober- und Unterteil (1b, 1d). Das eingerastete Ende des Oberteils (1b′) ist entsprechend dem halbkreisförmigen Nasenstück (1a˝) oben abgerundet und nach innen zu abgeschrägt.According to Figure 1, a protective strip (1) made of hard synthetic resin is attached to a window or door frame (3) by means of an equally wide and long tape (2) with an adhesive layer (2a) made of foamed, that is, soft synthetic resin, and together with this at a lateral distance A , which is filled with contact foam or insulating wool (10), stored in the masonry (5). Tightness of the wall plaster against moisture arriving from the outside is achieved by the fact that on the lower part (1d) of the protective strip (1) carrying the adhesive tape, a reinforcing fabric (8) made of synthetic resin-coated silk glass extends into the plaster layer (6, 6a) made of hard synthetic resin upper part (1b) is pressed, which is resiliently engaged with one end (1b ') in an undercut nose piece (1a˝) of semicircular shape of the side wall (1a) facing the masonry (1d) of the lower part (1d). The other end (1b˝) of the upper part engages in an undercut side wall (1c) of the lower part with the reinforcement fabric penetrating from here into the plaster layer. In this pressed and locked state, the surfaces of the upper and lower part (1b, 1d) facing the plaster layer are aligned. The latched end of the upper part (1b ') is rounded off according to the semicircular nose piece (1a˝) and beveled inwards.

An die Oberfläche des Oberteils (1b), die vorzugsweise glatt ist, aber auch aufgerauht oder gerillt sein kann, stößt eine am Mauerwerk (5) angeklebte wärmedämmende Faserplatte (9) an, die zusammen mit dem herausragenden Teil des Armierungsgewebes (8) in eine Spachtelmassenschicht (6a) eingebettet ist. Eine innere Aussparung (1e) ist von der dem Mauerwerk (5) abgewandten Seitenwand (1c) vorgesehen, deren Außenkante (1a′) in bekannter Weise als Abziehkante für den Oberputz dient.On the surface of the upper part (1b), which is preferably smooth, but can also be roughened or grooved, abuts a heat-insulating fiberboard (9) glued to the masonry (5), which together with the protruding part of the reinforcing fabric (8) Filler layer (6a) is embedded. An inner recess (1e) is provided in the side wall (1c) facing away from the masonry (5), whose outer edge (1a ') serves in a known manner as a peeling edge for the finishing coat.

Die Schutzleiste (1) trägt eine über einen Kerbeinschnitt (4a) von Hand leicht abbrechbare Schutzlasche (4), die teilweise über die Breite des Fensteroder Türrahmens (3) reicht; ferner trägt sie einen dorthin weisenden Steg (4a), dessen Höhe der stärke des Klebands (2) entspricht. Durch den Steg (4a) liegt die Schutzlasche (4) parallel zu dem darunterliegenden Bauteil (3), sodaß mit der Schutzleiste (1) der gegenüberliegenden Leibungsseite Höhengleichheit besteht, und die auf das Adhäsiv-Klebeband (4b) anzudrückende Schutzfolie (7) in einer Ebene über den Bauteilen (3) liegt.The protective strip (1) carries a protective flap (4) which can be easily broken off by hand via a notch cut (4a) and which partially extends over the width of the window or door frame (3); it also carries a web (4a) pointing there, the height of which corresponds to the thickness of the adhesive (2). Through the web (4a), the protective flap (4) is parallel to the component (3) underneath, so that the protective strip (1) on the opposite reveal side is level and the protective film (7) to be pressed onto the adhesive tape (4b) one level above the components (3).

Nach Beendigung des Mauerputzvorgangs wird die Schutzfolie (7) abgezogen, und die Schutzlasche (4) wird am Kerbeinschnitt (4a) von Hand abgebrochen oder abgezogen.After the masonry cleaning process has been completed, the protective film (7) is pulled off, and the protective flap (4) is broken off or pulled off by hand at the notch cut (4a).

Nach Figur 2 wird die Dichtheit des Mauerputzes dadurch erreicht, daß das jenes Klebeband (2) tragende Unterteil (1d) der Schutzleiste (1) in ein Oberteil (1b) von etwa gleicher Wandstärkz übergeht, das über ein Verbindungsstück (1c) von verminderter Wandstärke S umgeklappt und unter Zwischenlage des von hier aus in die Putzschicht eindringenden Armierungsgewebes (8) an jenes Oberteil angedrückt und mit einem freien Ende (1b′) in ein hinterschnittenes Nasenstück (1a˝) der dem Mauerwerk (5) abgewandten Seitenwand (1a) eingerastet ist. Dabei wird das nach innen zu abgeschrägte freie Ende (1b′) dieses Oberteils über das zur Putzschicht (6, 6a) hin abgerundete Nasenstück gedrückt.According to Figure 2, the tightness of the plaster is achieved in that the adhesive tape (2) carrying the lower part (1d) of the protective strip (1) merges into an upper part (1b) of approximately the same wall thickness, which is of reduced wall thickness via a connecting piece (1c) S folded down and with the interposition of the reinforcing fabric (8) penetrating into the plaster layer from here pressed onto that upper part and locked with a free end (1b ') into an undercut nose piece (1a˝) of the side wall (1a) facing away from the masonry (5) is. The inward tapered free end (1b ') of this upper part is pressed over the nose piece rounded towards the plaster layer (6, 6a).

Auch hier stößt an die Oberfläche des Oberteils (1b) eine am Mauerwerk (5) angeklebte wärmedämmende Faserplatte (9) an, die zusammen mit dem herausragenden Teil des Armierungsgewebes (8) in eine Spachtelmassenschicht (6a) eingebettet ist. Eine innere Aussparung (1e) ist in der dem Mauerwerk abgewandten Seitenwand (1a) vorgesehen, deren Außenseite (1a) in bekannter Weise als Abziehkante für den Oberputz dient und deren Vorderkante mit den Dreiecks-Höckern (1f) mit dem Putz eine Verzahnung bilden.Here too, the surface of the upper part (1b) abuts a heat-insulating fiberboard (9) glued to the masonry (5), which is embedded in a filler layer (6a) together with the protruding part of the reinforcing fabric (8). An inner recess (1e) is provided in the side wall (1a) facing away from the masonry, the outside (1a) of which, in a known manner, serves as a peeling edge for the top plaster and the front edge of which forms a toothing with the triangular cusps (1f) with the plaster.

Figur 2a unterscheidet sich nur dadurch, daß die Auflagefläche der Seitenwand (1a) für den Putz (6) so schmal ist, daß eine innere Aussparung eventuell entbehrlich ist.Figure 2a differs only in that the contact surface of the side wall (1a) for the plaster (6) is so narrow that an internal recess may be unnecessary.

Bei Figur 2 und 2a ist die Schutzlasche (4) wie bei Figur 1 ausgebildet.In Figures 2 and 2a, the protective tab (4) is designed as in Figure 1.
