Description

Die Erfindung betrifft eine Gebäudewandkonstruktion nach dem Oberbegriff des Anspruchs 1. DE-A-9107425 U offenbart solch eine Gebäudewandkonstruktion.The invention relates to a building wall construction according to the preamble of claim 1. DE-A-9107425 U discloses such a building wall construction.

Eine den heutigen Anforderungen genügende Gebäudewandkonstruktion erfordert u.a. die thermische Optimierung der Gebäudewand. Zur Reduzierung von Wärmeverlusten in der Gebäudewand werden Wärmedämm-Verbundsysteme eingesetzt. Die Verwendbarkeit von Wärmedämm-Verbundsystemen wird durch bauaufsichtliche Zulassungen geregelt. Ein wesentlicher Bestandteil für die Einhaltung der Qualität und Sicherheit der Wärmedämm-Verbundsysteme ist der Brandschutz.A building wall construction satisfying today's requirements requires, inter alia. the thermal optimization of the building wall. Thermal insulation composite systems are used to reduce heat losses in the building wall. The usability of composite thermal insulation systems is regulated by building inspectorate approvals. An essential element for the maintenance of the quality and safety of the thermal insulation composite systems is the fire protection.

In Wärmedämm-Verbundsystemen wird bevorzugt Polystyrol-Hartschaum in Form von Platten eingesetzt. Dieser Werkstoff ist brennbar und bildet im Brandfall brennende Tropfen aus, die brandausbreitend wirken können. Die Sturzkanten über Fenstern und Türen unterliegen im Falle eines Flammenaustritts aus dem Gebäude besonders hohen Beanspruchungen. Bei Wärmedämm-Verbundsystemen mit einer Dämmschichtdicke > 100 mm kann es hierbei zum Öffnen der Sturzkante und somit zur Brandweiterleitung kommen. Gerade diese Wärmedämm-Verbundsysteme mit einer Dämmschichtstärke > 100 mm werden zunehmend eingesetzt.In thermal insulation composite systems, polystyrene rigid foam in the form of plates is preferably used. This material is flammable and emits burning drops in the event of a fire, which can spread fire. The lintel edges over windows and doors are subject to particularly high stresses in the event of flame escaping from the building. For thermal insulation composite systems with an insulation layer thickness> 100 mm, this can lead to the opening of the lintel edge and thus to fire propagation. Especially these thermal insulation composite systems with an insulation thickness> 100 mm are increasingly used.

Aus diesem Grund ist es üblich, wie zum Beispiel in der Technischen Systeminfo 6 "Wärmedämm-Verbundsysteme zum Thema Brandschutz" des Fachverbandes Wärmedämmsysteme e.V. beschrieben oder wie in den allgemeinen bauaufsichtlichen Zulassungen für Wärmedämm-Verbundsysteme festgelegt, oberhalb der Gebäudeöffnungen einen 200 mm hohen Streifen aus Mineralwolle vollflächig zu verkleben. Der seitliche Überstand muss links und rechts des Sturzes mindestens 300 mm betragen. Im Brandfall treten im Sturzbereich von Gebäudeöffnungen durch die herausschlagenden Flammen die höchsten Temperaturen auf, so dass der Polystyrol-Hartschaum im Sturzbereich schmilzt. Insbesondere bei hohen Dämmstoffdicken (> 100 mm Dicke) besteht dadurch die Gefahr der Brandausweitung, weil sich große Mengen an flüssigem Polystyrol im Sturzbereich ansammeln und nach bestimmter Brandzeit als brennende Flüssigkeit nach außen durchbrechen und sich über die Fassade ergießen. Dabei werden insbesondere auch Bewohner und Rettungsmannschaft gefährdet.For this reason, it is customary, as described for example in the Technical System Info 6 "Thermal insulation composite systems on fire protection" of the Association Thermal insulation systems eV or as specified in the general building inspectorate approvals for thermal insulation composite systems, above the building openings a 200 mm high strip Glue mineral wool over the entire surface. The lateral projection must be left and right of the fall at least 300 mm. In the event of fire, the highest temperatures occur in the lintel area of building openings due to the striking flames, so that the polystyrene hard foam melts in the lintel area. Especially at high insulation thicknesses (> 100 mm thickness) there is a risk of fire expansion, because large amounts of liquid polystyrene accumulate in the lintel area and break after a certain burn time as a burning liquid to the outside and pour over the facade. In particular, residents and rescue teams are endangered.

Auch in das Wärmedämm-Verbundsystem integrierte Rollladenkästen stellen potentielle Gefahrenquellen bezüglich der Branderweiterung dar. Deshalb werden Rollladenkästen vollständig mit Mineralwolle überdämmt. Die Überdeckung der Rollladenkästen muss an beiden Seiten und oben mindestens 50 mm betragen, die seitliche Einbindung der Mineralwolle links und rechts der Gebäudeöffnung muss mindestens 300 mm betragen.Roller shutter boxes integrated into the thermal insulation composite system also represent potential sources of danger with regard to fire expansion. Therefore, roller shutter boxes are completely covered with mineral wool. The overlapping of the roller shutter boxes must be at least 50 mm on both sides and at the top, the lateral integration of the mineral wool on the left and right of the building opening must be at least 300 mm.

Der Wechsel von der Wärmedämmplatte aus Polystyrol-Hartschaum oder einem anderen brennbaren Material auf die Mineralwolleschicht erfordert einen relativ hohen Aufwand bei der Bauausführung. Mineralwolleschichten besitzen darüber hinaus andere bauphysikalische Eigenschaften als Polystyrol-Hartschaum, so dass es zu Abzeichnungen im Oberputz und auch zu Rissbildungen an den Ecken der Gebäudeöffnungen kommen kann und damit die Haltbarkeit der Putzschichten beeinträchtigt werden kann .The change of the thermal insulation board made of polystyrene foam or other combustible material on the mineral wool layer requires a relatively high effort in the construction. Mineral wool layers also have other physical properties than polystyrene hard foam, so that it can lead to signs in the top coat and also to cracks at the corners of the building openings and thus the durability of the plaster layers can be affected.

Wenn im folgenden von Wärmedämmplatten die Rede ist, versteht es sich, dass es sich bei einer Wärmedämmplatte jeweils um eine einzelne einschichtige Wärmedämmplatte oder-matte oder um eine aus mehreren übereinander gelagerten Wärmedämmplatten oder-matten zusammengesetzte mehrlagige oder mehrschichtige Wärmedämmplatte oder Wärmedämmmatte handelt. Die Wärmedämmplatten können aus organischem Schaumstoffmaterial, z.B. Polystyrol, oder anderen Kunststoffen oder anderen Stoffen wie Holzfasern oder ähnlichen Materialien, z.B. auch aus Verbundmaterial bestehen.According to the invention this object is achieved with a building wall construction according to claim 1.

Vorzugsweise besteht die Panzerschicht aus mindestens zwei Komponenten. Eine Gewebeschicht, vorzugsweise Glasfasergewebe, ist in eine Schicht aus mineralischen Armierungsmitteln, beispielsweise ein mineralischer Klebemörtel, integriert, so dass sich nach dem Aushärten des Klebemörtels eine feuerhemmende formstabile Panzerschicht ausbildet. Vorteilhafterweise kann zusätzlich eine Metallfolie, ein Metallgewebe oder ein Metallgitter oder eine perforierte oder nicht perforierte Metallplatte oder eine Platte aus nicht brennbarem Material, z.B. Bauplatte, vorzugsweise Faserzementplatte oder Gipsplatte, in die Panzerschicht integriert werden.Preferably, the armor layer consists of at least two components. A fabric layer, preferably glass fiber fabric, is integrated in a layer of mineral reinforcing agents, for example a mineral adhesive mortar, so that after hardening of the adhesive mortar, a fire-retardant rigid armor layer is formed.

Vorzugsweise weist die Wärmedämmplatte an der Frontseite und/oder an der unteren Stirnseite eine Panzerschicht auf, die als Teil einer die Rückseite der Wärmedämmplatte mit der Frontseite des Rollladenkastens und der Vorderseite des Sturzes verbindenden Panzerschicht ausgebildet ist. Das heißt, die Panzerschicht umgreift mindestens eine Kante der Wärmedämmplatte und ist dort als Panzerwinkelschicht ausgebildet.In embodiments with arranged at the bottom of the lintel roller shutter box is provided that the bottom of the lintel preferably arranged flush with the front of the lintel roller shutter box is overlapped by one or more the lintel cross-thermal insulation panels. The heat-insulating panel preferably has an armor layer on the front side and / or on the lower front side, which is formed as part of an armor layer connecting the rear side of the thermal insulation panel to the front side of the roller shutter box and the front of the lintel. That is, the armor layer surrounds at least one edge of the thermal insulation board and is formed there as a tank angle layer.

Bei Ausführungen mit an der Vorderseite des Sturzes angeordnetem Rollladenkasten ist vorgesehen, dass der an der Vorderseite des Sturzes angeordnete Rollladenkasten an seiner Frontseite und an seiner Oberseite von einer oder mehreren Wärmedämmplatten übergriffen ist, vorzugsweise jeweils unter Zwischenschaltung einer Panzerschicht, die als Teil einer mindestens eine Kante der Wärmedämmplatte oder eine Kante des Rollladenkastens umgreifende Panzerwinkelschicht ausgebildet ist.In embodiments with arranged at the front of the lintel roller shutter box is provided that arranged at the front of the lintel Roller shutter box is overlapped on its front side and at its top of one or more thermal insulation panels, preferably each with the interposition of an armor layer, which is formed as part of at least one edge of the thermal insulation board or an edge of the shutter box encompassing armored angle layer.

Vorteilhafterweise sind die Panzerschichten als ohne Unterbrechung durchgehende Schichten ausgebildet, vorzugsweise die unteren Kanten der Wärmedämmplatte bzw. Wärmedämmplatten U-förmig oder mäanderförmig umgreifend und die nicht am Sturz anliegenden Bereiche des Rollladenkastens übergreifend.Advantageously, the armor layers are formed as uninterrupted continuous layers, preferably the lower edges of the thermal insulation board or thermal insulation boards U-shaped or meandering embracing and not adjacent to the fall areas of the shutter box cross.

Die als Panzerwinkelschicht ausgebildeten Abschnitte der Panzerschicht weisen mindestens zwei rechtwinklig zueinander angeordnete Schenkel auf. In einem Eckbereich weist die Panzerwinkelschicht drei rechtwinklig zueinander angeordnete Schenkel auf.The armor layer sections formed as an armor angle layer have at least two legs arranged at right angles to each other. In a corner region, the armor angle layer has three legs arranged at right angles to one another.

Vorteilhafterweise kann die Gewebeschicht als Gewebestreifen ausgebildet sein, die sich dem Kantenprofil der Wärmedämmplatte bzw. des Rollladenkastens winkelig anschmiegen als sog. Winkel oder Gewebewinkel. Sie können beispielsweise zur Ausbildung von Eckwinkeln mit Einschnitten ausgebildet sein, die in der Längsachse oder parallel zur Längsachse des Gewebestreifens angeordnet sind. Auf diese Weise können sie als eine Ecke umgebende Eckwinkel ausgebildet sein, wobei jeweils zwei der drei Schenkel einen Winkel von 90° bilden, oder als Eckwinkel mit einem Schenkel, der zu einem anderen der drei Schenkel einen Winkel von - 90° bzw. von 270° einschließt. Auf diese Weise können beliebig zueinander winklig angeordnete Flächen mit solchen Gewebewinkeln unter Ausbildung einer geschlossenen Panzerwinkelschicht überdeckt sein.Advantageously, the fabric layer can be formed as a fabric strip, which conform to the edge profile of the thermal insulation board or the roller shutter box angled as so-called. Angle or fabric angle. They may be formed, for example, for the formation of corner angles with cuts, which are arranged in the longitudinal axis or parallel to the longitudinal axis of the fabric strip. In this way, they can be formed as a corner surrounding corner angle, wherein each two of the three legs form an angle of 90 °, or as a corner angle with a leg, to another of the three legs at an angle of - 90 ° or 270 ° includes. In this way, any surfaces arranged at an angle to one another can be covered with such fabric angles to form a closed armored angular layer.

Es kann von Vorteil sein, dass die im Winkel verlegten Gewebestreifen als vorgefertigte Winkel ausgebildet sind, beispielsweise als steife Gewebe-Winkel oder als dünne, vorteilhafterweise perforierte Metall-Winkel bzw. Metallfolien-Winkel, Metallgewebe-Winkel oder Metallgitter-Winkel oder Winkel aus perforierten oder nicht perforierten Platten aus nicht brennbarem Material, z.B.

Vorteilhafterweise sind die in der Schicht aus mineralischen Armierungsmitteln, beispielsweise mineralischer Klebemörtel, eingebetteten Winkel so angeordnet, dass sich zwei Schenkel von zwei Winkeln flächig überlappen. Auf diese Weise ist die Panzerschicht in allen Bereichen mit annähernd gleicher hoher Bruch- und Brandfestigkeit ausgebildet und lediglich kleine Randbereiche der Panzerschicht sind nur aus mineralischen Armierungsmitteln verminderter Festigkeit ausgebildet.Advantageously, the embedded in the layer of mineral reinforcing agents, such as mineral adhesive mortar, angles are arranged so that two legs overlap two areas of two angles. In this way, the armor layer is formed in all areas with approximately the same high resistance to breakage and fire and only small edge areas of the armor layer are formed only of mineral reinforcing agents reduced strength.

Es ist weiter vorgesehen, dass die Wärmedämmplatten an ihrer Außenseite, vorzugsweise an ihrer Frontseite und/oder an ihrer unteren Stirnseite eine Oberputzschicht aufweisen, vorzugsweise auf der Armierungsschicht aufgebracht. Dabei ist es von Vorteil, dass die Armierungsschicht ein guter Haftgrund für die Oberputzschicht ist und stabile Kanten ausbildet, so dass die verputzte Gebäudewand einen optisch guten Eindruck vermittelt.It is further provided that the heat-insulating panels have on their outer side, preferably on their front side and / or on their lower end face an outer plaster layer, preferably applied to the reinforcing layer. It is advantageous that the reinforcing layer is a good primer for the top coat and stable edges forms, so that the plastered building wall gives a visually good impression.

Fig. 1 zeigt eine Gebäudewand 14 mit einer Fensteröffnung 12 mit einem Sturz 10 mit an der Unterseite des Sturzes 10 untergehängtem Rollladenkasten 20. Der Rollladenkasten 20, beispielsweise aus Holz oder Kunststoff ausgebildet, ist mit seiner Oberseite auf der Unterseite des Sturzes 10 mit nicht dargestellten Montageelementen befestigt und liegt mit seinen seitlichen Begrenzungsflächen an der senkrechten Laibungswand der Rohbauöffnung des Fensters 22 an, wie näher in Fig. 9 dargestellt. Die Vorderseite des Sturzes 10 und die Frontseite des Rollladenkastens 20 bilden dabei eine Ebene.Fig. 1 shows a building wall 14 with a window opening 12 with a lintel 10 with the underside of the lintel 10 untergehängtem roller shutter box 20. The shutter box 20, for example made of wood or plastic, with its upper side on the underside of the lintel 10 with not shown Fastened mounting elements and is located with its lateral boundary surfaces on the vertical reveal wall of the shell opening of the window 22, as shown in more detail in Fig. 9. The front of the lintel 10 and the front of the roller shutter box 20 form a plane.

Die Gebäudewand 14 ist mit quaderförmigen Wärmedämmplatten 30 mit verhältnismäßig großer Wandstärke beschichtet. Die Wärmedämmplatten 30 sind aus Polystyrol-Hartschaum ausgebildet. Die verhältnismäßig große Wandstärke, beispielsweise etwa 300 mm, ist für eine hochwertige Wärmedämmung der Gebäudewand 14 erforderlich. Die Wärmedämmplatten 30 sind mit Klebemörtel 32 auf der Außenfläche der Gebäudewand 14 befestigt. Die Vorderseite des Sturzes 10 und die Frontseite des Rollladenkastens 20 sind mit der Wärmedämmplatte 30 gemeinsam überdeckt, die an der der Vorderfläche des Sturzes 10 zugewandten Rückseite mit einer Schicht aus Klebemörtel 32 versehen ist.The building wall 14 is coated with cuboid thermal insulation panels 30 with a relatively large wall thickness. The thermal insulation panels 30 are formed of polystyrene foam. The relatively large wall thickness, for example about 300 mm, is required for a high-quality thermal insulation of the building wall 14. The thermal insulation panels 30 are secured with adhesive mortar 32 on the outer surface of the building wall 14. The front side of the lintel 10 and the front side of the roller shutter box 20 are jointly covered with the thermal insulation panel 30, which is provided on the front surface of the lintel 10 facing rear with a layer of adhesive mortar 32.

Die untere Stirnseite der Wärmedämmplatte 30 wird von einer Panzerschicht 36 U-förmig umgriffen. Diese Panzerschicht 36 besteht aus drei U-förmig zueinander angeordneten Schenkeln und umgreift mit zwei benachbarten Schenkeln jeweils eine Kante der Wärmedämmplatte 30. Sie bildet somit eine winklige, d.h. im Querschnitt L-förmige Panzerschicht, auch Panzerwinkelschicht 36' genannt, jeweils eine an der frontseitigen unteren horizontalen Stirnkante der Wärmedämm-Platte und eine an der hinteren dem Rollladenkasten zugewandten unteren horizontalen Stirnkante der Wärmedämmplatte. Die Panzerschicht bzw. die Panzerwinkelschicht 36' ist jeweils mehrschichtig aufgebaut. Sie besteht aus einer Gewebeschicht, im allgemeinen als winkelförmige Gewebeschicht, ein sogenannter Gewebewinkel 38 ausgebildet, aus Glasfasergewebe, Metallgewebe, Metallgitter oder Metallfolie, eingebettet in eine Schicht aus mineralischem Klebemörtel 40. (s. Fig. 2). Diese Gewebeschicht 38 und Klebemörtelschicht 40 sind in der Konfiguration als Panzerwinkelschicht 36' jeweils winklig, d.h. die Kante der Wärmedämmplatte umgreifend ausgebildet. Die horizontalen Schenkel der beiden Panzerwinkelschichten 36' bilden einen Überlappungsbereich, in welchem die horizontalen Gewebewinkelschenkel 38 überlappen und die horizontalen Schenkel der Klebemörtelschicht 40 ineinander übergehen. Die unteren Stirnflächen des Rollladenkastens 20 sind beiderseits der Rollladenaustrittsöffnung durch Schienen 20a überdeckt, beispielsweise aus Metall oder Kunststoff ausgebildet. Dadurch, dass die unteren Stirnfläche der Wärmedämmplatte 30 vollständig durch die Panzerschicht 36 untergriffen wird, indem die Panzerschicht 36 als eine die Wärmedämmplatte 30 an der Unterseite umgreifende U-förmige Wanne ausgebildet ist, wirkt die nicht entflammbare Panzerschicht 36 als Brandbarriere und verhindert im Brandfall das Heruntertropfen brennender Polystyroltropfen. Auf diese Weise wird im Bereich des Sturzes 10 die Brandausbreitung auf tiefer liegende Abschnitte der Gebäudewand 14 bzw. auf die Wärmedämmplatten 30 verhindert.The lower end face of the thermal insulation panel 30 is surrounded by an armor layer 36 U-shaped. This armor layer 36 consists of three legs arranged in a U-shape relative to one another and, with two adjacent legs, respectively surrounds one edge of the heat-insulating panel 30. It thus forms an angled, ie. in cross-section L-shaped armor layer, also called armor angle layer 36 ', one at the front lower horizontal end edge of the thermal insulation panel and one at the rear of the shutter box facing lower horizontal end edge of the thermal insulation board. The armor layer or the armor angle layer 36 'is in each case of multilayer construction. It consists of a fabric layer, generally formed as an angular fabric layer, a so-called fabric angle 38, made of glass fiber fabric, metal mesh, metal mesh or metal foil, embedded in a layer of mineral adhesive mortar 40th (see Fig. 2). This fabric layer 38 and adhesive mortar layer 40, in the configuration as armor angle layer 36 ', are each angled, i. E. the edge of the thermal insulation board formed encompassing. The horizontal legs of the two armor angle layers 36 'form an overlap region in which the horizontal fabric angle legs 38 overlap and the horizontal legs of the adhesive mortar layer 40 merge into one another. The lower end faces of the roller shutter box 20 are covered on both sides of the roller shutter outlet opening by rails 20a, formed for example of metal or plastic. Characterized in that the lower end face of the thermal insulation board 30 is completely attacked by the armor layer 36 by the armor layer 36 is formed as a heat-insulating panel 30 at the bottom embracing U-shaped tub, the non-flammable armor layer 36 acts as a fire barrier and prevents fire in the case Dropping of burning polystyrene drops. In this way, in the region of the lintel 10, the spread of fire to deeper sections of the building wall 14 or to the thermal insulation panels 30 is prevented.

Die Wärmedämmplatte 30 weist an ihrer Frontseite und unteren Stirnseite eine Armierungsschicht 42 mit Armierungsgewebe 42a und eine Oberputzschicht 44 auf. Dabei schließt die Armierungsschicht 42 an die Panzerschicht 36 nahtlos an, wobei das Armierungsgewebe 42a auch in der Panzerschicht 36 die Gewebewinkel 38 überdeckend angeordnet ist (s. Fig. 2). Die Oberputzschicht 44 ist auch auf die untere Stirnseite der Wärmedämmplatte 30 und die Fensterlaibung aufgebracht, so dass die von außen optisch sichtbaren Bereiche der Panzerschicht 36 von der Oberputzschicht 44 überdeckt sind.The thermal insulation panel 30 has on its front side and lower end side a reinforcing layer 42 with reinforcement fabric 42a and a topcoat layer 44. In this case, the reinforcing layer 42 connects seamlessly to the armor layer 36, the reinforcing fabric 42a also being arranged in the armor layer 36 so as to cover the fabric angles 38 (see FIG. 2). The topcoat layer 44 is also on the the lower end face of the thermal insulation panel 30 and the window reveal applied, so that the externally visually visible areas of the armor layer 36 are covered by the top coat layer 44.

Fig. 3 zeigt ein weiteres Ausführungsbeispiel. Der Rollladenkasten 20 mit Schienen 20a, die seine unteren Stirnseiten überdecken, ist außen vor dem Sturz 10 angeordnet. Die Rückwand des Rollladenkastens 20 ist dabei auf der Vorderseite des Sturzes 10 durch nicht dargestellte Montageelemente befestigt. Die Wärmedämmplatte 30 ist im unteren Bereich, wo sich der Rollladenkasten 20 befindet, um das Maß der Tiefe des Rollladenkastens und der Stärke der Panzerschicht 36 ausgespart und überdeckt mit ihrem frontseitigen Abschnitt 30' die Frontseite des Rollladenkastens 20. Auf diese Weise wirkt die aus Wärmedämmplatten 30 gebildete Wärmedämmschicht der Gebäudewand 14 im Bereich des Sturzes 10 optisch so wie die in Fig. 1 dargestellte Wärmedämmschicht, gebildet aus der Wärmedämmplatte 30. Die Panzerschicht 36 umgreift den Abschnitt 30' der Wärmedämmplatte 30, die vordere Unterkante, die Frontseite und die Oberseite des Rollladenkastens 20 und die an den Abschnitt 30' angrenzende Unterseite sowie die untere Hinterkante der Wärmedämmplatte 30. Auf diese Weise bildet die Panzerschicht 36 einen im Querschnitt mäanderförmigen Trog, der die Unterstirnseite der Wärmedämmplatte 30 vollständig umgreift. Die Panzerschicht 36 ist aus im Querschnitt L-förmigen Panzerwinkelschichten 36' zusammengesetzt. Im dargestellten Fall handelt es sich um vier Panzerwinkelschichten 36'. Die erste Panzerwinkelschicht 36' umgreift die untere vordere Stirnkante der Wärmedämmplatte, die zweite Panzerwinkelschicht 36' umgreift die hintere dem Rollladenkasten zugewandte untere Stirnkante der Wärmedämmplatte 30. Die dritte Panzerwinkelschicht 36' umgreift die obere horizontale Kante des Rollladenkastens 20 und die vierte Panzerwinkelschicht 36' umgreift die hintere der Wand angrenzende horizontale Kante der Wärmedämmplatte 30. Die Panzerwinkelschicht 36', jeweils im Querschnitt L-förmig, weist mehrere in Klebemörtel eingebettete Gewebewinkel auf, wie in Fig. 5 bis 8 im Einzelnen dargestellt. Wie in Figur 3 zu erkennen ist, grenzt an den auf der Gebäudewand 14 angeordneten hinteren streifenförmig senkrechten Abschnitt der Panzerwinkelschicht 36' nahtlos die Unterkante der Klebemörtelschicht 32 an, mit der die Wärmedämmplatte 30 mit ihrer Rückseite auf der Vorderseite der Gebäudewand 14 befestigt ist.Fig. 3 shows another embodiment. The roller shutter box 20 with rails 20 a, which cover its lower end faces, is arranged outside the lintel 10. The rear wall of the roller shutter box 20 is fastened on the front side of the lintel 10 by mounting elements, not shown. The thermal insulation panel 30 is recessed at the bottom of where the shutter box 20 is to the extent of the depth of the shutter box and the thickness of the armor layer 36 and covered with its front portion 30 ', the front side of the roller shutter box 20. In this way, the acts of thermal insulation panels 30 formed thermal barrier layer of the building wall 14 in the area of the lintel 10 visually as the thermal barrier coating shown in Fig. 1, formed from the thermal insulation board 30. The armor layer 36 surrounds the portion 30 'of the thermal insulation board 30, the front lower edge, the front and the top of the Roller shutter box 20 and the underside adjacent to the portion 30 'and the lower trailing edge of the thermal insulation panel 30. In this way, the armor layer 36 forms a meandering in cross section trough, which completely surrounds the lower end face of the thermal insulation panel 30. The armor layer 36 is composed of cross-sectionally L-shaped armor angle layers 36 '. In the case shown, there are four armored angle layers 36 '. The first armor angle layer 36 'surrounds the lower front end edge of the thermal insulation panel, the second armor angle layer 36' surrounds the rear lower edge of the thermal insulation panel 30 facing the shutter box. The third armor angle layer 36 'engages around the upper horizontal edge of the shutter box 20 and the fourth armor angle layer 36' surrounds The armor angle layer 36 ', each in cross-section L-shaped, has several embedded in adhesive mortar fabric angle, as shown in detail in Fig. 5 to 8. As can be seen in Figure 3, adjoins the arranged on the building wall 14 rear strip-shaped vertical portion of the armor angle layer 36 'seamlessly Lower edge of the adhesive mortar layer 32, with which the heat insulating plate 30 is fixed with its back on the front of the building wall 14.

Die Wärmedämmplatte 30 weist an ihrer Frontseite die Armierungsschicht 42, die dort die Panzerschicht 36 fortsetzt, und die Oberputzschicht 44 auf, wobei das Armierungsgewebe 42a auch in der Panzerschicht 36 die Gewebewinkel 38 überdeckend angeordnet ist. Die Armierungsschicht 42 und die Oberputzschicht 44 sind auch auf die untere Stirnseite der Wärmedämmplatte 30 und die Fensterlaibung aufgebracht, so dass die von außen optisch sichtbaren Bereiche der Panzerschicht 36 von der Oberputzschicht 44 überdeckt sind (s. Fig. 3).The thermal insulation panel 30 has on its front side the reinforcing layer 42, which continues there the armor layer 36, and the topcoat layer 44, wherein the reinforcing fabric 42a is arranged in the armor layer 36, the fabric angle 38 overlapping. The reinforcing layer 42 and the outer plaster layer 44 are also applied to the lower end face of the thermal insulation panel 30 and the window reveal, so that the externally visually visible areas of the armor layer 36 are covered by the outer layer 44 (see Fig. 3).

Fig. 4 zeigt eine Variante des in Fig. 3 dargestellten Ausführungsbeispiels. Dabei liegen die Vorderseite der Wärmedämmplatte 30 und die Vorderseite des Rollladenkastens 20 in einer Ebene. Die unteren Stirnseiten des Rollladenkastens sind beiderseits der Rollladenaustrittsöffnung mit Schienen 20a überdeckt. Die Panzerschicht 36 umgreift den unteren Abschnitt der Wärmedämmplatte 30 U-förmig. Die Panzerschicht 36 ist wiederum aus im Querschnitt L-förmigen Panzerwinkelschichten 36' zusammengesetzt. Die eine Panzerwinkelschicht 36' umgreift die untere vordere Stirnkante der Wärmedämmplatte, die andere Panzerwinkelschicht 36' umgreift die hintere der Gebäudewand 14 zugewandte untere Stirnkante der Wärmedämmplatte 30. Die Panzerschicht 36 weist mehrere in Klebemörtel eingebettete winkelförmige Gewebeschichten auf, wie in Fig. 5 bis 8 im Einzelnen dargestellt.Fig. 4 shows a variant of the embodiment shown in Fig. 3. In this case, the front of the thermal insulation panel 30 and the front of the shutter box 20 lie in a plane. The lower end faces of the roller shutter box are covered on both sides of the roller shutter outlet opening with rails 20a. The armor layer 36 surrounds the lower portion of the thermal insulation panel 30 U-shaped. The armor layer 36 is in turn composed of cross-sectionally L-shaped armor angle layers 36 '. The one armor angle layer 36 'surrounds the lower front end edge of the thermal insulation panel, the other armor angle layer 36' surrounds the rear of the building wall 14 facing lower end edge of the thermal insulation board 30. The armor layer 36 has a plurality embedded in adhesive mortar angular tissue layers, as in Fig. 5 to 8 shown in detail.

Die Wärmedämmplatte 30 weist an ihrer Frontseite die Armierungsschicht 42, die dort die Panzerschicht 36 fortsetzt, und die Oberputzschicht 44 auf, wobei das Armierungsgewebe 42a auch in der Panzerschicht 36 die Gewebewinkel 38 überdeckend angeordnet ist. Die Vorderseite des Rollladenkastens 20 ist ebenfalls mit der Armierungsschicht 42 und der Oberputzschicht 44 versehen.The thermal insulation panel 30 has on its front side the reinforcing layer 42, which continues there the armor layer 36, and the topcoat layer 44, wherein the reinforcing fabric 42a is arranged in the armor layer 36, the fabric angle 38 overlapping. The front of the roller shutter box 20 is also provided with the reinforcing layer 42 and the top coat layer 44.

Fig. 5 bis 8 zeigen schematisch am Beispiel eines auf der Gebäudewand 14 über einer Fensteröffnung 12 angeordneten Rollladenkastens 20 den schichtweisen Aufbau der im Querschnitt L-förmigen Panzerwinkelschicht 36' aus Fig. 2. Diese besteht, wie in Fig. 2 dargestellt, aus in mineralischem Klebermörtel 40 eingebetteten Gewebewinkeln 38. In den Figuren 5 bis 8 sind sukzessive aufgebrachte Gewebewinkel als 38a, 38b, 38c und 38d gezeigt. Die oben liegenden Gewebewinkel sind jeweils kreuzschraffiert gekennzeichnet, darunter liegende Gewebewinkel aus vorherigen Figuren grau hinterlegt.5 to 8 show schematically by way of example a roller shutter box 20 arranged on the building wall 14 above a window opening 12, the layered structure of the L-shaped tank angle layer 36 'of FIG consists, as shown in Fig. 2, of embedded in mineral adhesive mortar 40 fabric angles 38. In Figures 5 to 8 successively applied fabric angles are shown as 38a, 38b, 38c and 38d. The uppermost fabric angles are each marked cross-hatched, underlying fabric angles from previous figures are highlighted in gray.

Fig. 5 zeigt einen Gewebewinkel 38a, dessen einer Schenkel einen streifenförmigen Abschnitt der oberhalb des Rollladenkastens 20 angrenzenden Gebäudewand 14 überdeckt und dessen anderer Schenkel die Oberseite und den oberen Abschnitt der Stirnseiten des Rollladenkastens 20 überdeckt. Seine Längenabmessung ist deshalb größer als die Breite des Rollladenkastens 20, so dass überstehende Abschnitte verbleiben, welche die oberen Kanten der linken und der nicht dargestellten rechten Stirnseite des Rollladenkastens umgreifen, beispielsweise um 9 cm. Die Längenabmessung des Gewebewinkels 38a, der an beiden Endabschnitten längs seiner Winkelkante um etwa 9 cm eingeschnitten ist, ist in diesem Beispiel deshalb um etwa 18 cm größer als die Breite des Rollladenkastens 20.5 shows a fabric angle 38a, one leg of which covers a strip-shaped section of the building wall 14 adjoining above the roller shutter box 20 and the other leg of which covers the upper side and the upper section of the front sides of the roller shutter box 20. Its length dimension is therefore greater than the width of the roller shutter box 20, so that projecting portions remain surrounding the upper edges of the left and the unillustrated right front side of the shutter box, for example by 9 cm. The length dimension of the fabric angle 38a, which is cut at both end portions along its angular edge by about 9 cm, is in this example therefore about 18 cm larger than the width of the roller shutter box 20th

Fig. 6 zeigt in der Darstellung grau hinterlegt den Gewebewinkel 38a aus Fig. 5 und ausgezeichnet einen wannenförmigen Gewebewinkel 38b, der die Frontseite des Rollladenkastens 20, streifenförmige Abschnitte seiner linken und rechten Stirnseite und seiner Oberseite umgreift. Auf diese Weise überdeckt der Gewebewinkel 38b Abschnitte des Gewebewinkels 38a. Der Gewebewinkel 38b umgreift die Oberseite des Rollladenkastens 20 im dargestellten Beispiel um etwa 9 cm und die linke und rechte Stirnseite um etwa 10 cm. Der Gewebewinkel 38b bildet folglich zwei Eckwinkel aus, welche die vorderen oberen Ecken des Rollladenkastens 20 umgreifen.Fig. 6 shows in gray shaded representation the fabric angle 38a of Fig. 5 and excellent a trough-shaped fabric angle 38b, which surrounds the front side of the shutter box 20, strip-shaped portions of its left and right front side and its top. In this way, the fabric angle 38b covers portions of the fabric angle 38a. The fabric angle 38b surrounds the top of the roller shutter box 20 in the example shown by about 9 cm and the left and right front side by about 10 cm. The fabric angle 38b thus forms two corner angles which embrace the front upper corners of the roller shutter box 20.

Fig. 7 zeigt in der Darstellung grau hinterlegt die Gewebewinkel 38a, 38b aus den Fig. 5 und 6 und ausgezeichnet einen Gewebewinkel 38c, der mit einem Schenkel einen Streifen der Oberseite und die linke Stirnseite des Rollladenkastens 20 überdeckt und mit dem anderen Schenkel einen diesem Abschnitt des Rollladenkastens benachbarten Abschnitt der Gebäudewand 14 überdeckt. Der Gewebewinkel 38c ist deshalb an beiden Endabschnitten längs seiner Winkelkante etwa 10 cm eingeschnitten und die Längenabmessung ist etwa 20 cm größer als die Höhe des Rollladenkastens 20. Auf diese Weise werden ein überstehender oberer Abschnitt, der die Oberseite des Rollladenkastens 20 um beispielsweise 10 cm umgreift und ein überstehender unterer Abschnitt, der nicht benötigt und deshalb abgetrennt ist, istgebildet.
Ein spiegelbildlich zum Gewebewinkel 38c ausgebildeter, in der Teilschnittdarstellung nicht abgebildeter Gewebewinkel überdeckt die ebenfalls nicht dargestellte rechte Stirnseite, Abschnitte der Oberseite des Rollladenkastens 20 sowie einen benachbarten Abschnitt der Gebäudewand 14 in analoger Weise.Fig. 7 shows in gray gray depicts the fabric angle 38a, 38b of Figs. 5 and 6 and excellent tissue angle 38c, which covered with a leg strip of the top and the left end of the shutter box 20 and the other leg a this Covered section of the roller shutter box adjacent portion of the building wall 14. The fabric angle 38c is therefore at both end portions along its angular edge 10 cm and the length dimension is about 20 cm greater than the height of the roller shutter box 20. In this way, a projecting upper portion, which surrounds the top of the shutter box 20 by, for example, 10 cm and a protruding lower portion, which is not needed and therefore is separated, is formed.
A mirror image of the fabric angle 38c trained, not shown in the partial sectional view fabric angle covers the right side also not shown, sections of the top of the shutter box 20 and an adjacent portion of the building wall 14 in an analogous manner.

Die Gewebewinkel 38c überdecken Abschnitte der Gewebewinkel 38a und 38b.The fabric angles 38c cover portions of the fabric angles 38a and 38b.

Fig. 8 zeigt grau hinterlegt die Gewebewinkel 38a, 38b, 38c aus den Fig. 5 bis 7 und einen ausgezeichneten Gewebewinkel 38d, der mit einem Schenkel den Gewebewinkel 38b im unteren Abschnitt der Frontseite des Rollladenkastens 20 überdeckt. Der andere Schenkel des Gewebewinkels 38d ragt nach vorn und überdeckt die Unterseite des Abschnitts 30' der nicht dargestellten frontseitigen Wärmedämmplatte 30 (s. Fig. 3). Die Längenabmessung des Gewebewinkels 38d ist gleich der horizontalen Längenabmessung des Rollladenkastens 20.FIG. 8 shows, in a gray background, the fabric angles 38a, 38b, 38c from FIGS. 5 to 7 and an excellent fabric angle 38d, which covers the fabric angle 38b in the lower section of the front side of the roller shutter box 20 with one leg. The other leg of the fabric angle 38d protrudes forward and covers the underside of the portion 30 'of the front thermal insulation panel 30, not shown (see Fig. 3). The length dimension of the fabric angle 38 d is equal to the horizontal length dimension of the roller shutter box 20.

Dabei sind in der Panzerwinkelschicht 36' mindestens zwei Schenkel von zwei Gewebewinkeln einander überlappend angeordnet, so dass die Gewebewinkel eine geschlossene Gewebeschicht bilden, die von mineralischem Klebemörtel durchsetzt ist. Auf diese Weise sind die unteren Stirnseiten inklusiv der unteren Kanten der in den Figuren 5 bis 8 nicht dargestellten Wärmedämmplatte 30 und des Rollladenkastens 20 vollständig mit Panzerwinkelschichten überdeckt, wobei die Eckbereiche von Panzereckwinkelschichten umgriffen sind.5 to 8 show by way of example the layered structure of the illustrated in Fig. 2 in cross-section L-shaped armor angle layer 36 'of fabric angles 38a, 38b, 38c, 38d, which are embedded in non-illustrated mineral adhesive mortar. At least two legs of two fabric angles are arranged overlapping each other in the armor angle layer 36 ', so that the fabric angles form a closed fabric layer which is penetrated by mineral adhesive mortar. In this way, the lower end faces, including the lower edges of the heat insulation board 30 and the shutter box 20, not shown in FIGS. 5 to 8, are completely covered with armor angle layers, the corner areas being encompassed by armored corner layers.
