The invention relates to a thermal insulation element for the reveal of window openings or door openings on buildings or for use as a completion of a thermal insulation of a building wall, comprising:
  1. (A) a plate-shaped thermal insulation component, in the attached state of the heat-insulating element
    • in the case of the soffit, sitting in front of the soffit,
    • or, in the case of the outer wall of the building wall, in front of the outer wall of the building wall;
  2. (B) a base component at the front end of the thermal insulation element, which is combined with the thermal insulation component
    • and, in the case of the soffit insert, in the attached state of the heat-insulating element, adjacent to a window frame inserted in the window opening or a door frame inserted into the door opening;
  3. (c) wherein the base component is made of plastic and has higher strength than the thermal barrier component;
  4. (d) and a plaster bar attached to the base component
    • and which, in the case of the insert for the soffit, in the installed state of the heat-insulating element, sits at the transition between the window frame or door frame and the base component.

Beim konventionellen Bauen von Gebäuden ist man bei Fensteröffnungen oder Türöffnungen in der Vergangenheit meist so vorgegangen, dass man den Fensterrahmen oder Türrahmen lagerichtig in der betreffenden Öffnung positioniert hat und dort z.B. mit Blechlaschen oder mit durch den Rahmen hindurch gebohrten Dübeln fixiert hat. Dann hat man den Spalt zwischen dem Rahmen und der Laibung mit Polyurethanschaum ausgeschäumt, um so den Rahmen in der Laibung fertig zu befestigen und den Spalt zu dichten. Anschließend wurde die Laibung sowohl außenseitig des Rahmens als auch innenseitig des Rahmens verputzt. In den letzten Jahren hat man vor dem Verputzen außenseitig von dem Rahmen die Laibung z.B. mit Platten aus geschäumtem Polystyrol verkleidet und damit dort eine Wärmedämmung erstellt. Schließlich wurde Putz auf die Wärmedämmung aufgebracht.In the conventional construction of buildings, in window openings or door openings in the past, the procedure has usually been to position the window frame or door frame in the correct position in the opening in question and fix it there with sheet metal tabs or with dowels drilled through the frame. Then, the gap between the frame and the soffit was foamed with polyurethane foam so as to fix the frame in the soffit and seal the gap. Subsequently, the soffit was plastered both on the outside of the frame and on the inside of the frame. In recent years, before the plastering on the outside of the frame, the soffit, for example, clad with sheets of foamed polystyrene and thus created a thermal insulation there. Finally, plaster was applied to the thermal insulation.

Diese Art der Fertigstellung des Gebäudes im Bereich der Fensteröffnungen oder Türöffnungen war nicht optimal. Der erhärtete Polyurethanschaum (sog. Montageschaum) stand normalerweise sowohl außenseitig als auch innenseitig ein Stück über den Fensterrahmen oder Türrahmen hinaus, und der Überstand musste mühsam von Hand mit einem Messer abgeschnitten werden, damit die Wärmedämmung eng anschließend an den Rahmen angebracht werden kann. Wenn hierbei nicht sorgsam gearbeitet wird, steht entweder der Montageschaum an einigen Stellen noch etwa vor, so dass die Wärmedämmung nicht ganz an den Rahmen herangerückt werden kann und dort ein Spalt verbleibt. Oder der Montageschaum hatte an einigen Stellen überhaupt nicht über den Rahmen vorgestanden. In diesem Fall verbleiben kleinere Lufträume zwischen dem Montageschaum und der Wärmedämmung. Der geschilderte Spalt zwischen Wärmedämmung und Rahmen oder die geschilderten Hohlräume zwischen Montageschaum und Wärmedämmung füllen sich bei entsprechenden Witterungsbedingungen mit feuchter Luft, und aus dieser feuchten Luft kann bei entsprechenden Witterungsbedingungen Wasser auskondensieren. Das auskondensierte Wasser ist schädlich für die Lebensdauer des Rahmens und führt zu lokaler Durchfeuchtung des Mauerwerks und/oder der Wärmedämmung; Beides verschlechtert den Wärmedurchgangswiderstand wesentlich.This type of completion of the building in the area of the window openings or door openings was not optimal. The hardened polyurethane foam (so-called mounting foam) was usually both outside and inside a piece beyond the window frame or door frame out, and the supernatant had to be laboriously cut by hand with a knife, so that the heat insulation can be closely attached to the frame afterwards. If this is not done carefully, is either the mounting foam in some places still approximately, so that the heat insulation can not be brought close to the frame and there remains a gap. Or the mounting foam had not protruded over the frame in some places at all. In this case, smaller air spaces remain between the mounting foam and the thermal insulation. The described gap between the thermal insulation and the frame or the described cavities between mounting foam and insulation fill in appropriate weather conditions with humid air, and from this humid air can condense water under appropriate weather conditions. The condensed water is harmful to the life of the frame and leads to local moisture penetration of the masonry and / or thermal insulation; Both significantly deteriorate the heat transfer resistance.

Die geschilderten Arbeiten beim konventionellen Fertigstellen des Gebäudes im Bereich von Fensteröffnungen und Türöffnungen sind mühsam und wenig rationell.The described work in the conventional completion of the building in the area of window openings and door openings are tedious and not very efficient.

Mit der Erfindung wird die Aufgabe gelöst, die Fertigstellung der Laibung nach dem Einpositionieren des Fensterrahmens oder des Türrahmens rationeller zu gestalten und dabei ein wärmetechnisch und bauphysikalisch verbessertes Ergebnis zu liefern.With the invention, the problem is solved to make the completion of the soffit after the positioning of the window frame or the door frame rational and thereby to provide a thermally and physically improved physical outcome.

Durch Einsatz des erfindungsgemäßen Wärmedämmelements kann die Arbeitskraft am Bau durch Platzieren eines einzigen vorgefertigten Wärmedämmelements mehrere Arbeitsschritte, die früher beim konventionellen Bauen erforderlich waren, ersetzen. Die Arbeitskraft platziert nur noch das erfindungsgemäße Wärmedämmelement z.B. durch Befestigung an der Laibungsfläche. Dadurch ist Alles für das anschließende Verputzen optimal vorbereitet.By using the thermal insulation element according to the invention, the worker can replace several work steps in the construction by placing a single prefabricated thermal insulation element, which were previously required in conventional construction. The worker only places the thermal insulation element of the invention, for example by attachment to the soffit surface. As a result, everything is optimally prepared for the subsequent plastering.

Ein Wärmedämmelement für die Laibung von Fensteröffnungen oder Türöffnungen an Gebäuden, mit den in Anfangsabsatz der Beschreibung angeführten Merkmale (a), (b), (d), aber nicht mit Merkmal (c), ist aus DE 198 57 383 A1 , Ausführungsform gemäß Fig. 3, bekannt. Bei der dortigen Ausführungsform gemäß Fig. 4 ist zwar eine Faserzementplatte in einer Eckausnehmung einer Styroporplatte eingelegt. Diese Faserzementplatte bildet jedoch nicht einen Stirnende-Basisbestandteil für das gesamte Wärmedämmelement.A thermal insulation element for the reveal of window openings or door openings on buildings, with the features mentioned in the opening paragraph of the description (a), (b), (d), but not with feature (c), is out DE 198 57 383 A1 , Embodiment of FIG. 3, known. In the local embodiment according to FIG. 4, a fiber cement plate is indeed inserted in a corner recess of a styrofoam plate. However, this fiber cement board does not form a front end base component for the entire thermal insulation element.

DE 91 07 425 U1 offenbart einen Rolladensturzkasten, an dem eine Styroporplatte befestigt ist. Am Ende der Styroporplatte ist eine Anputzleiste vorhanden. Der Rolladensturzkasten hat offensichtlich eine höhere Festigkeit als die Styroporplatte, so dass die Verhältnisse umgekehrt wie bei der Erfindung sind. DE 91 07 425 U1 discloses a roller shutter lintel to which a styrofoam plate is attached. At the end of Styrofoam plate is a plastering strip available. The roller shutter box obviously has a higher strength than the polystyrene plate, so that the conditions are reversed as in the invention.

Der Basisbestandteil hat eine vergleichsweise höhere Festigkeit und der Wärmedämmbestandteil eine vergleichsweise niedrigere Festigkeit.The basic component has a comparatively higher strength and the thermal insulation component has a comparatively lower strength.

Auf diese Weise gibt der Basisbestandteil dem gesamten Wärmedämmelement eine größere Stabilität, als wenn für das Wärmedämmen der Laibung nur konventionelle Wärmedämmplatten eingesetzt werden. Der besonders wichtige Anschluss an den Rahmen wird durch den Basisbestandteil geleistet, der formstabiler als der Wärmedämmbestandteil ist und eine niedrigere Wärmeleitzahl haben kann. Die Anputzleiste muss nicht mehr in einem separaten Arbeitsgang maßgerecht auf dem Rahmen angebracht werden, sondern wird automatisch durch den Akt der Anbringung des Wärmedämmelements korrekt am Übergang zwischen dem Rahmen und dem Basisbestandteil platziert.In this way, the base component gives the entire thermal insulation element greater stability than when only conventional thermal insulation panels are used for thermal insulation of the soffit. The particularly important connection to the frame is provided by the basic component, which is more stable than the thermal insulation component and can have a lower thermal conductivity. The plasterboard no longer needs to be custom-fitted to the frame in a separate operation, but is automatically placed correctly at the transition between the frame and the base component by the act of attaching the thermal insulation element.

Vorzugsweise weist der Basisbestandteil auf seiner Rückseite (das ist die der dem Zentrum der Fensteröffnung oder Türöffnung zugewandten Vorderseite entgegengesetzte Rückseite) eine Kanalvertiefung auf, die im angebrachten Zustand des Wärmedämmelements zu dem Spalt zwischen dem Fensterrahmen oder Türrahmen und der Laibung offen ist, wobei entlang des Basisbestandteils verteilt mehrere Verbindungskanäle zwischen einer zugänglichen, vorderen Oberfläche des Basisbestandteils und dem Inneren der Kanalvertiefung vorhanden sind.Preferably, the base component has on its rear side (that is, the rear side facing the center of the window opening or door opening front side) a channel recess which is open in the attached state of the heat-insulating element to the gap between the window frame or door frame and the soffit, along the Base component distributed a plurality of connecting channels between an accessible front surface of the base component and the interior of the channel recess are present.

Mit dem so ausgestalteten Wärmedämmelement hat man die Möglichkeit, Kunststoff durch die Verbindungskanäle in die Kanalvertiefung einzubringen und dort so aufschäumen zu lassen, dass dort keine Hohlräume mehr verbleiben. Noch stärker ist die Möglichkeit bevorzugt, den Kunststoff über die Kanalvertiefung auch in den Spalt zwischen dem Rahmen und der Laibung einzubringen und dort aufschäumen zu lassen, wodurch der Rahmen endgültig in der Laibung lagebefestigt wird. Kontrolle der richtigen Einbringung von Kunststoff in diesen Spalt kann von der dem Wärmedämmelement entgegengesetzten Seite des Rahmens her optisch erfolgen. Aber auch die Alternative, den Rahmen zunächst konventionell durch Montageschaum in der Laibung zu befestigen und danach nur die anschließenden Hohlräume mit Kunststoffschaum auszufüllen, der über die Verbindungskanäle eingebracht worden ist, ist möglich. Auf jeden Fall hat man die bisherige Notwendigkeit, den Montageschaum genau zu beschneiden, vermieden.With the heat insulation element designed in this way, it is possible to introduce plastic through the connecting channels into the channel depression and to allow it to foam there so that no cavities remain there. Even more, the possibility is preferred to introduce the plastic through the channel recess in the gap between the frame and the soffit and let it foam there, whereby the frame is finally fixed in position in the soffit. Checking the correct introduction of plastic into this gap can be made optically from the side of the frame opposite the heat-insulating element. But also the alternative, the frame first conventionally by mounting foam in the soffit to fasten and then fill only the subsequent cavities with plastic foam, which has been introduced via the connecting channels, is possible. In any case, you have the previous need to cut the mounting foam exactly avoided.

Vorzugsweise ist der Übergang zwischen dem Basisbestandteil und dem Wärmedämmbestandteil mit einer Stufe ausgebildet. Dies schafft bessere Bedingungen für die gegenseitige Vereinigung zwischen dem Basisbestandteil und dem Wärmedämmbestandteil.Preferably, the transition between the base component and the thermal insulation component is formed with a step. This creates better conditions for mutual association between the base constituent and the thermal barrier constituent.

Vorzugsweise ist an dem Wärmedämmelement, insbesondere der Anputzleiste des Wärmedämmelements, ein Stück Armierungsgewebe befestigt. Das Armierungsgewebe verbessert die Haftungsbedingungen für den Putz auf dem Wärmedämmelement und stellt dauerhafte Rissfreiheit des Putzes sicher.Preferably, a piece of reinforcing fabric is attached to the heat-insulating element, in particular the plastering strip of the heat-insulating element. The reinforcing fabric improves the adhesion conditions for the plaster on the thermal insulation element and ensures permanent crack-free of the plaster.

Vorzugsweise wird das Wärmedämmelement mit mehreren Wärmedämmbestandteil-Breiten zur Bewältigung unterschiedlicher Laibungsbreiten, gemessen rechtwinklig zur Ebene des Fensterrahmens oder Türrahmens, lieferbar. Dies kann eine eine Lieferung "genau nach Maß" entsprechend der Laibungsbreite, gemessen vom Fensterrahmen oder Türrahmen bis zur Außenseite der Gebäudewand, optional auch einschließlich dortiger Wärmedämmung, sein. Oder es kann eine Lieferung mit größerer als der erforderlichen Breite vorgesehen sein, so dass die Überbreite dann am Bau abgeschnitten wird.Preferably, the thermal insulation element is available with a plurality of thermal barrier component widths to cope with different reveal widths, measured at right angles to the plane of the window frame or door frame. This can be a delivery "made to measure" according to the soffit width, measured from the window frame or door frame to the outside of the building wall, optionally including local thermal insulation. Or it can be provided a delivery with greater than the required width, so that the excess width is then cut in the construction.

Vorzugsweise besteht der Basisbestandteil aus Kunststoff, z.B. extrudiertem massivem Kunststoff. Stärker bevorzugt ist jedoch geschäumter Kunststoff, wobei Polyurethan-Schaumkunststoff (Wärmeleitzahl 0,025) besonders geeignet ist.Preferably, the base component is plastic, e.g. extruded solid plastic. However, foamed plastic is more preferred, with polyurethane foam plastic (thermal conductivity 0.025) being particularly suitable.

Der Wärmedämmbestandteil ist vorzugsweise mit geschäumtem Kunststoff, insbesondere geschäumtem Polystyrol (Wärmeleitzahl 0,04), oder mit Fasermaterial, insbesondere Steinwolle, aufgebaut.The thermal insulation component is preferably constructed with foamed plastic, in particular foamed polystyrene (thermal conductivity 0.04), or with fiber material, in particular rock wool.

Die einzubauenden Wärmedämmelemente müssen naturgemäß eine passende Länge zum Einbau an der linken Rahmenseite oder zum Einbau an der rechten Rahmenseite oder zum Einbau beim oberen, waagerechten Rahmenteil oder - insbesondere bei Fensterrahmen - zum Einbau beim unteren, waagerechten Rahmenteil haben. Auch hier kann man entweder Lieferung nach Maß ab Fabrik vorsehen oder eine Kürzung der Wärmedämmelement-Länge unmittelbar am Einbauort. Für den Übergang zwischen waagerecht und senkrecht kann man entweder auf Gehrung geschnittene Wärmedämmelement-Enden vorsehen oder mit stumpfem, rechtwinkligem Anstoßen arbeiten.The thermal insulation elements to be installed must naturally have a suitable length for installation on the left frame side or for installation on the right frame side or for installation in the upper, horizontal frame part or - especially in window frames - for installation at the lower, horizontal frame part. Again, you can either provide custom delivery from factory or a reduction in the thermal insulation element length immediately on Installation. For the transition between horizontal and vertical you can either provide mitred cut heat insulation ends or work with blunt, right-angled abutment.

Das nach den Prinzipien der Erfindung ausgebildete Wärmedämmelement kann nicht nur bei der Laibung von Fensteröffnungen oder Türöffnungen eingesetzt werden, sondern auch als Abschluss an einem Endbereich der Wärmedämmung einer Gebäudewand, vorzugsweise als sog. unterer Sockelabschluss. Konkret ist somit ein weiterer Aspekt der Erfindung die Verwendung eines Wärmedämmelements, welches einen Basisbestandteil mit vergleichsweise höherer Festigkeit und, damit vereinigt, einen plattenförmigen Wärmedämmbestandteil mit vergleichsweise niedrigerer Festigkeit aufweist, als Abschluss einer Wärmedämmung einer Gebäudewand. Auch hier hat man Vorteile des rationalen Arbeitens mit einem vorgefertigten Wärmedämmelement. Der Basisbestandteil erbringt bessere Unempfindlichkeit gegen Beschädigungen gerade im kritischen unteren Endbereich der Wärmedämmung.The thermal insulation element formed according to the principles of the invention can be used not only in the reveal of window openings or door openings, but also as an end to an end portion of the thermal insulation of a building wall, preferably as a so-called. Lower base termination. Specifically, therefore, another aspect of the invention is the use of a heat-insulating element which has a base component with comparatively higher strength and, combined with it, a plate-shaped thermal insulation component with comparatively lower strength, as the conclusion of a thermal insulation of a building wall. Here, too, one has advantages of rational working with a prefabricated thermal insulation element. The basic component provides better insensitivity to damage, especially in the critical lower end of the thermal insulation.

Eine Anputzleiste ist nicht zwingend erforderlich, aber durchaus bevorzugt. Auch hier kann an dem Wärmedämmelement ein Stück Armierungsgewebe befestigt sein, weil ja in der Regel Putz auf die Außenseite der Gebäudewand-Wärmedämmung aufzubringen ist. Die Anputzleiste kann mit Tropfkante ausgebildet sein.A plaster molding is not mandatory, but quite preferable. Again, a piece of reinforcing fabric may be attached to the thermal insulation element, because yes, plaster is usually applied to the outside of the building wall insulation. The plaster strip can be formed with drip edge.

Die Erfindung und bevorzugte Ausgestaltungen der Erfindung werden nachfolgend von zeichnerisch dargestellten Ausführungsbeispielen noch näher erläutert. Es zeigt:

  • Fig. 1 ein Wärmedämmelement, angebracht an einer Laibungsfläche, im Horizontalschnitt;

  • Fig. 2 a thermal insulation element attached to the outer surface of a building wall, in vertical section.

Bei dem Ausführungsbeispiel gemäß Fig. 1 ist ein horizontal geschnittenes Mauerwerk 2 zu sehen mit einer Laibung bzw. Laibungsfläche 4, die in Fig. 1 nach links zum Inneren einer Fensteröffnung 6 oder Türöffnung weist. Mit dem Pfeil A ist die Richtung zur Außenseite des Gebäudes bezeichnet und mit dem Pfeil I die Richtung zur Innenseite des Gebäudes. In der Fensteröffnung 6 ist ein Fensterrahmen 8 positioniert, wobei der Fensterrahmen aus Metall oder Kunststoff oder Holz bestehen kann. Die Ebene des Fensterrahmens 8 ist von links nach rechts in Fig. 1, rechtwinklig zur Laibungsfläche 4.In the embodiment according to Fig. 1 is a horizontally cut masonry 2 to see with a soffit or soffit 4, the in Fig. 1 to the left to the interior of a window opening 6 or door opening points. The arrow A indicates the direction to the outside of the building and the arrow I the direction to the inside of the building. In the window opening 6, a window frame 8 is positioned, wherein the window frame may be made of metal or plastic or wood. The plane of the window frame 8 is from left to right in FIG Fig. 1 at right angles to the soffit surface 4.

Ein Wärmedämmelement 10 ist an der Laibungsfläche 4 befestigt, z.B. durch nicht eingezeichnete Bolzen mit flächengroßen Scheiben auf der in Fig. 1 linken Seite des Wärmedämmelements 10 oder durch Klebemörtel. Das Wärmedämmelement 10 hat als Hauptbestandteile einen Basisbestandteil 12, einen Wärmedämmbestandteil 14 und eine Anputzleiste 16 mit einem Stück Armierungsgewebe 18.A thermal insulation element 10 is attached to the soffit surface 4, for example by not drawn bolts with area-sized slices on the in Fig. 1 left side of the thermal insulation element 10 or by adhesive mortar. The thermal insulation element 10 has as main components a base component 12, a thermal insulation component 14 and a plastering strip 16 with a piece of reinforcement fabric 18th

Der Basisbestandteil 12 hat im gezeichneten Horizontalschnitt gleichsam einen mehrfach abgewinkelten Verlauf. Oben in Fig. 1 verläuft er parallel zur Laibungsfläche 4, dann folgt ein rechtwinkliges Abknicken zum Zentrum der Fensteröffnung 6 hin, dann folgt wiederum ein rechtwinkliges Abknicken zu einem Verlauf parallel zur Laibungsfläche 4 und mit Abstand zu dieser, und schließlich folgt ein rechtwinkliges Abknicken zu einem Verlauf auf die Laibungsfläche 4 zu, aber endend ein Stück vor der Laibungsfläche 4. Durch diese Querschnittsform ist im in Fig. 1 oberen Bereich des Basisbestandteils 12 eine Stufe 20 gebildet und im in Fig. 1 unteren Bereich des Basisbestandteils eine Kanalvertiefung 22.The base component 12 has in the drawn horizontal section as it were a multiple angled course. Top in Fig. 1 it runs parallel to the soffit surface 4, then follows a right-angled bending toward the center of the window opening 6, then again followed by a right-angled bend to a course parallel to the soffit 4 and at a distance from this, and finally follows a right-angled bending to a course on the soffit area 4 to, but ending a piece in front of the soffit 4. By this cross-sectional shape is in the in Fig. 1 upper portion of the base component 12 a Level 20 is formed and im in Fig. 1 lower portion of the base component a channel depression 22nd

Der Wärmedämmbestandteil 14 ist mit dem Basisbestandteil 12 vereinigt, z.B. durch Anschäumen. Zur Verbesserung des Zusammenhalts können an der Verbindungsfläche 24 in dem Basisbestandteil Vertiefungen 26 vorgesehen sein, in welche das Material des Wärmedämmbestandteils 14 nach Art von Verankerungszapfen eintritt. Insgesamt erstreckt sich der Wärmedämmbestandteil 14 plattenförmig von unten nach oben in Fig. 1 entlang der Laibung 4. Die bei Blickrichtung von links nach rechts in Fig. 1 sichtbare Breite des Wärmedämmbestandteils 14 ist so groß, dass der gesamte Teil der Laibungsbreite zwischen dem Fensterrahmen 8 und der Außenoberfläche des Mauerwerks (oben in Fig. 1, aber nicht gesondert eingezeichnet) von dem Wärmedämmelement 10 überdeckt ist.The thermal insulation component 14 is combined with the base component 12, for example by foaming. In order to improve the cohesion, recesses 26 may be provided on the connection surface 24 in the base component, into which the material of the thermal insulation component 14 enters in the manner of anchoring pins. Overall, the thermal insulation component 14 extends plate-shaped from bottom to top in Fig. 1 along the soffit 4. The viewed from left to right in Fig. 1 visible width of the thermal insulation component 14 is so large that the entire part of the soffit width between the window frame 8 and the outer surface of the masonry (above in Fig. 1 but not shown separately) is covered by the thermal insulation element 10.

Die Anputzleiste 16 ist im linken unteren Eckbereich des Basisbestandteils 12 an diesem angeklebt. Unten in Fig. 1 hat die Anputzleiste 16 ein SchaumstoffKlebeband 28. Bei der Anbringung des Wärmedämmelements 10 wird dieses so weit in Richtung Fensterrahmen 8 geschoben, dass das Schaumstoff-Klebeband 28 in Klebekontakt mit dem Fensterrahmen 8 kommt. An der Anputzleiste 16 ist das Stück Armierungsgewebe 18 durch Ultraschallschweißung befestigt; es erstreckt sich entlang der in Fig. 1 nach links gewandten Vorderfläche des Wärmedämmelements 10. Außerdem weist die Anputzleiste 16 eine Schutzlasche 30, auf der eine Schutzfolie klebend befestigt werden kann, auf. Nach Beendigung der Putzarbeiten wird die Schutzlasche 30 durch Abknicken von der Anputzleiste 16 abgebrochen und mit der Schutzfolie entsorgt.The plaster strip 16 is glued to the left lower corner region of the base component 12 at this. Down in Fig. 1 when the heat-insulating element 10, this is pushed so far in the direction of the window frame 8 that the foam adhesive tape 28 comes into adhesive contact with the window frame 8. On the plaster molding 16, the piece reinforcing fabric 18 is attached by ultrasonic welding; it stretches along in Fig. 1 In addition, the plaster bar 16 has a protective tab 30 on which a protective film can be adhesively attached, on. After completion of the cleaning work, the protective tab 30 is broken off by kinking of the plaster bar 16 and disposed of with the protective film.

Es wird betont, dass ohne Weiteres auch andere Arten von Anputzleisten alternativ vorgesehen sein können.It is emphasized that other types of cleaning strips can be provided as an alternative without any problem.

In Fig. 1 erkennt man auch einen von mehreren Verbindungskanälen 30, welche über die (in Fig. 1 rechtwinklig zur Zeichnungsebene verlaufende) Länge des Wärmedämmelements 10 verteilt vorgesehen sind. Nachdem das Wärmedämmelement 10 an der Laibung 4 angebracht worden ist, kann durch die Verbindungskanäle 30 Kunststoff in die Kanalvertiefung 22 und von dort weiter in einen Spalt 32 zwischen dem Fensterrahmen 8 und der Laibungsfläche 4 eingebracht werden. Beim anschließenden Aufschäumen füllt der Kunststoff die genannten Räume vollständig aus, wobei sich Kunststoffschaum noch in den Spaltraum neben das Schaumstoffklebeband ausbreitet.In Fig. 1 one recognizes one of several connecting channels 30, which over the (in Fig. 1 perpendicular to the plane of the drawing extending) length of the heat-insulating element 10 are provided distributed. After the heat-insulating element 10 has been attached to the soffit 4, can through the Connecting channels 30 plastic in the channel recess 22 and from there into a gap 32 between the window frame 8 and the soffit 4 are introduced. During the subsequent foaming, the plastic completely fills said spaces, with plastic foam still spreading in the gap next to the foam adhesive tape.

Beim Ausführungsbeispiel gemäß Fig. 2 besitzt Wärmedämmelement 10 ebenfalls als Hauptbestandteile den Basisbestandteil 12, den Wärmedämmbestandteil 14 und die Anputzleiste 16. Der Basisbestandteil 12 ist L-förmig, aber nach wie vor mit einer Stufe 20 ausgebildet. Die Anputzleiste 16 weist eine Tropfkante 34 auf.According to the embodiment Fig. 2 Heat insulating element 10 also has as main components the base component 12, the thermal insulation component 14 and the plaster molding 16. The base component 12 is L-shaped, but still formed with a step 20. The plaster strip 16 has a drip edge 34.

Es wird betont, dass das Laibungs-Wärmedämmelement nicht nur für den äußeren Laibungsbereich zwischen dem Fensterrahmen 8 oder Türrahmen und der Außenoberfläche der Gebäudewand eingesetzt werden kann (wie in Fig. 1 gezeichnet), sondern wahlweise auch für den inneren Teil der Laibung auf der Innenseite des Fensterrahmens 8 oder Türrahmens.It is emphasized that the soffit heat-insulating element can not only be used for the outer soffit area between the window frame 8 or door frame and the outer surface of the building wall (as in FIG Fig. 1 drawn), but optionally also for the inner part of the soffit on the inside of the window frame 8 or door frame.
