Definitions
- the invention relates to ventilated facade insulation according to the preamble of claim 1.
- a problem with facade insulation made of plastic foam panels is their behavior in the event of a fire.
- the insulation panels are usually not made of heat-resistant material and, on the other hand, a chimney effect is generated by the ventilation channels, which promotes rapid fire spreading, particularly in the vertical direction.
- the invention also relates to a flame arrester which is suitable for the construction of a facade insulation according to the invention.
- the flame arrester preferably has the shape of a bar that extends horizontally and that has a plurality of passage channels that connect the ventilation channels in the insulation plates of the wall sections located above and below the flame arrester and in which fire protection means are provided, through which the passage channels if an upper limit temperature occurs in the ventilation channels of the relevant wall insulation panel adjacent to the flame arrester, they are largely or completely closed.
- the passage channels in the flame barrier are preferably oriented with the same inclination as the ventilation channels in the plastic foam panels of the facade insulation adjacent to the flame barrier at the top and bottom.
- At least one fire protection plate made of a refractory material which foams up when exposed to heat, which advantageously consists essentially of water-containing sodium silicate reinforced with fibers or wire, is preferably arranged.
- the passage channels in the flame arrester and the properties of the fire protection plate, in particular the temperature at the start of the reaction and the foam volume produced, are coordinated with one another in such a way that the cross-sectional narrowing of the passage channels caused by the foaming of the fire protection plate is at least 80%. It is particularly favorable if the flame arrester also consists of a non-combustible and / or heat-insulating material.
- the following materials have at least one of these properties and are therefore suitable as a material for the flame arrester: asbestos fibers, mineral fiber wool, glass wool, cork, pearlite, foamed water glass, flame-retardant polyurethane or a mixture of at least two of these materials.
- the facade insulation attached to the building G shown in FIG. 1 is essentially constructed as described in EP-A - «. (note 84810196.0) and CH-PS 648 888 already mentioned above. It is composed of individual plastic foam panels P, which are equipped under their surface with a system of continuous vertical, or intersecting and interconnected, ventilation channels K inclined at 45 degrees to the vertical. The usual plaster or abrasion layer is on the plates P.
- the insulating facade is divided between the ground and upper floors of the building by a horizontal, beam-shaped flame arrester F into two sections 1 and 2.
- the flame arrester F which consists of a non-combustible insulating material, has a multiplicity of through channels 3 which connect the ventilation channels K in the plates P above and below the flame arrester F.
- These through-channels 3 are preferably dimensioned approximately the same as the ventilation channels K in the plates P and, furthermore, are preferably also oriented in the same way as these, ie at 45 degrees to the vertical, or also vertically.
- the number and arrangement of the fire protection panels 4 in the through channels 3 is of secondary importance. It is particularly important that the type of fire protection panels 4 and the dimensions sion of the through channels 3 are coordinated so that the cross-sectional area of the individual through channels is reduced by at least 80% in the event of fire. Preferably, the through channels 3 are practically completely blocked (100% reduction).
- the fire protection panels 4 consist, for example, of a water-containing sodium silicate with small amounts of organic additives. They can be mechanically reinforced with glass fibers or wires and coated with epoxy resin.
- a suitable fire protection panel of this type is e.g. offered under the brand name "PALUSOL” by the company BASF, D-6700 Ludwigshafen am Rhein.
- the beam-shaped flame arrester F e.g. flame retardant polyurethane, cork, glass wool, perlite, synthetic resin-bonded glass fiber plates, asbestos fiber plates or molded glass (foamed water glass) can be used as mentioned above.
- the number of flame arresters F in the insulating facade depends on their height. As a rule, there should be a flame arrester between two floors. In special cases, more or less flame arresters can of course also be provided in the entire facade.
- the fire protection plates 4 can be arranged in the through channels 3 in different ways.
- a particularly easy-to-assemble variant is shown in FIGS. 5 and 6.
- all fire protection panels are in the form of two long strips 5 and 6, which extend through the entire flame arrester.
- the fire protection strips 5 and 6 can simply be inserted or inserted lengthways due to the flexibility of the material from which the flame arrester is made.
- cutouts can also be provided for these strips or plates, in particular in the inner wall of the through-channels near the joint between the flame arrester and the foam plates.
- the fire protection panels are in a thin film e.g. made of aluminum, which is a good heat conductor and does not prevent the fire protection material from swelling when the critical temperature is reached.
- the insulation material of the facade insulation can have both heat and sound insulation.
- FIG. 7 and 8 of the flame arrestor according to the invention consists of two beam halves F1 and F2, F1 is so taken care of F2 that the passage channels 7 and 8 therein are freely connected to each other via an opening 11a in the parting line 11 are.
- the channel 7 leads in the upper half of the bar F1 in front of the common opening lla closer to the front wall A of the facade and is through its upper opening 7a with the ventilation channel K1 inclined at 45 ° of the upper facade area 1 in free connection. A parallel to this channel K1 'is also shown.
- the passage channel 8 is in the lower half of the beam F2 through its lower opening 8a with the ventilation channel K2 in the lower facade area 2 in free connection.
- Another channel K2 ' is shown parallel to the channel K2 inclined at 45 °.
- this transverse long channel 12 has recesses or grooves 12a and 12b, in which fire protection strips 9 and 10 are inserted.
- Each of these strips consists of a core 9a, 10a and an envelope 9b, 10b made of aluminum foil which is so loose that it does not hinder expansion of the core by foaming or swelling when the temperature e.g. in the channels K2, K2 ', etc. and in the subsequent section of the passage channel 8 reaches a critical limit at which foaming or the like.
- the fire protection strips 9 and 10 occur.

Abstract
Die Fassade ist aus Kunststoffschaumplatten (P) zusammengesetzt, welche unter der Oberfläche mit unter 45 Grad zur Vertikalen oder mit vertikal verlaufenden Belüftungskanälen (K) versehen sind. Die Fassade ist über ihre Höhe in Abschnitte unterteilt, wobei zwischen je zwei Abschnitten eine Flammensperre (F) vorgesehen ist. Die balkenförmige Flammensperre besteht aus einem nicht brennbaren Isolierstoff und besitzt eine Reihe von Durchgangskanälen (3) zur Verbindung der Beluftungskanäle in den angrenzenden Isolierschaumplatten. In den Durchgangskanälen befinden sich Brandschutzplatten (4) aus einem Material, da bei Hitzeeinwirkung aufschäumt, die Durchgangskanäle verschließt und dadurch die Brandausbreitung unterbindet.The facade is composed of plastic foam panels (P), which are provided under the surface with less than 45 degrees to the vertical or with vertical ventilation channels (K). The height of the facade is divided into sections, with a flame arrester (F) being provided between two sections. The bar-shaped flame arrester consists of a non-combustible insulating material and has a series of through-channels (3) for connecting the ventilation channels in the adjacent insulating foam panels. Fire protection panels (4) made of one material are located in the through ducts, as foaming when exposed to heat, closes the through ducts and thus prevents the spread of fire.
Description
Die Erfindung betrifft eine hinterlüftete Fassadenisolation gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to ventilated facade insulation according to the preamble of
Zur thermischen Isolierung von Gebäuden werden deren Fassaden vielfach mit Isolationen aus Kunststoffschaumplatten eingekleidet, welche unter der Oberfläche mit einem System von Belüftungskanälen versehen sind. Ein typisches Beispiel für eine solche hinterlüftete Fassade ist u.a. in der EP-A-........ (Anmeldung 84810196.0) und der CH-PS 648 888 beschrieben.For the thermal insulation of buildings, their facades are often clad with insulation made of plastic foam panels, which are provided with a system of ventilation channels underneath the surface. A typical example of such a ventilated facade is in EP-A -........ (application 84810196.0) and CH-PS 648 888.
Ein Problem bei Fassadenisolationen aus Kunststoffschaumplatten besteht in deren Verhalten im Brandfall. Einerseits bestehen die Isolationsplatten gewöhnlich nicht aus hitzefestem Material und andererseits wird durch die Belüftungskanäle eine Kaminwirkung erzeugt, welche eine rasche Brandausbreitung insbesondere in vertikaler Richtung begünstigt.A problem with facade insulation made of plastic foam panels is their behavior in the event of a fire. On the one hand, the insulation panels are usually not made of heat-resistant material and, on the other hand, a chimney effect is generated by the ventilation channels, which promotes rapid fire spreading, particularly in the vertical direction.
Durch die Erfindung soll nun dieses Problem gelöst werden, d.h., es soll eine hinterlüftete Fassadenisolation geschaffen werden, bei der eine Brandausbreitung weitestgehend unterbunden ist.This problem is now to be solved by the invention, i.e. a ventilated facade insulation is to be created in which fire spread is largely prevented.
Die erfindungsgemäße Fassadenisolation, die diesen Anforderungen gerecht wird, ist im Patentanspruch 1 beschrieben. Bevorzugte Ausführungsformen ergeben sich aus den abhängigen Ansprüchen.The facade insulation according to the invention, which meets these requirements, is described in
Die Erfindung betrifft auch gemäß einem weiteren Aspekt eine Flammensperre, die für den Aufbau einer erfindungsgemäßen Fassadenisolation geeignet st. Die Flammensperre hat dabei vorzugsweise die Gestalt eines Balkens, der sich horizontal erstreckt und der eine Vielzahl von Durchgangskanälen aufweist, welche die Belüftungskanäle in den Isolationsplatten der sich oberhalb und unterhalb der Flammensperre befindlichen Wandabschnitte miteinander verbinden und in welchen Brandschutzmittel vorgesehen sind, durch die die Durchgangskanäle bei Auftreten einer oberen Grenztemperatur in den an die Flammensperre angrenzenden Belüftungskanälen der betreffenden Wandisolationsplatte weitgehend bis vollständig verschlossen werden. Die Durchgangskanäle in der Flammensperre sind vorzugsweise mit der gleich Neigung verlaufend orientiert wie die Beluftungskanäle in den oben und unten an die Flammensperre angrenzenden Kunststoffschaumplatten der Fassadenisolation.According to a further aspect, the invention also relates to a flame arrester which is suitable for the construction of a facade insulation according to the invention. The flame arrester preferably has the shape of a bar that extends horizontally and that has a plurality of passage channels that connect the ventilation channels in the insulation plates of the wall sections located above and below the flame arrester and in which fire protection means are provided, through which the passage channels if an upper limit temperature occurs in the ventilation channels of the relevant wall insulation panel adjacent to the flame arrester, they are largely or completely closed. The passage channels in the flame barrier are preferably oriented with the same inclination as the ventilation channels in the plastic foam panels of the facade insulation adjacent to the flame barrier at the top and bottom.
In den Durchgangskanälen der Flammensperre ist vorzugsweise wenigstens eine Brandschutzplatte aus einem feuerfesten, bei Hitzeeinwirkung aufschäumenden Material, das vorteilhaft im wesentlichen aus mit Fasern oder Draht verstärktem wasserhaltigem Natriumsilikat besteht, angeordnet. Die Durchgangskanäle in der Flammensperre und die Eigenschaften der Brandschutzplatte,insbesondere Temperatur des Reaktionsbeginns und erzeugtes Schaumvolumen,sind so aufeinander abgestimmt, daß die durch das Aufschäumen der Brandschutzplatte verursachte Querschnittsverengung der Durchgangskanäle mindestens 80 % beträgt. Besonders günstig ist es, wenn auch die Flammensperre aus einem nichtbrennbaren und/oder wärmeisolierenden Material besteht. Die folgenden Materialien besitzen mindestens eine dieser Eigenschaften und eignen sich daher als Material für die Flammensperre: Asbestfasern, mineralische Faserwolle, Glaswolle, Kork, Perlit, geschäumtes Wasserglas, schwerentflammbares Polyurethan oder eine Mischung aus mindestens je zwei dieser Materialien.In the passage channels of the flame arrester, at least one fire protection plate made of a refractory material which foams up when exposed to heat, which advantageously consists essentially of water-containing sodium silicate reinforced with fibers or wire, is preferably arranged. The passage channels in the flame arrester and the properties of the fire protection plate, in particular the temperature at the start of the reaction and the foam volume produced, are coordinated with one another in such a way that the cross-sectional narrowing of the passage channels caused by the foaming of the fire protection plate is at least 80%. It is particularly favorable if the flame arrester also consists of a non-combustible and / or heat-insulating material. The following materials have at least one of these properties and are therefore suitable as a material for the flame arrester: asbestos fibers, mineral fiber wool, glass wool, cork, pearlite, foamed water glass, flame-retardant polyurethane or a mixture of at least two of these materials.

Die an dem in Fig. 1 dargestellten Gebäude G angebrachte Fassadenisolation ist im wesentlichen so aufgebaut, wie in der vorstehend schon angeführten EP-A-....... (Anm. 84810196.0) und der CH-PS 648 888 beschrieben. Sie ist aus einzelnen Kunststoffschaumplatten P zusammengesetzt, welche unter ihrer Oberfläche mit einem System von durchgehenden vertikal verlaufenden, oder sich kreuzenden und untereinander verbundenen,unter 45 Grad zur Vertikalen geneigt verlaufenden Belüftungskanälen K ausgestattet sind. Auf den Platten P befindet sich die übliche Putz- oder Abriebschicht.The facade insulation attached to the building G shown in FIG. 1 is essentially constructed as described in EP-A -....... (note 84810196.0) and CH-PS 648 888 already mentioned above. It is composed of individual plastic foam panels P, which are equipped under their surface with a system of continuous vertical, or intersecting and interconnected, ventilation channels K inclined at 45 degrees to the vertical. The usual plaster or abrasion layer is on the plates P.
Die Isolierfassade ist zwischen Erd- und Obergeschoß des Gebäudes durch eine horizontale, balkenförmige Flammensperre F in zwei Abschnitte 1 und 2 unterteilt. Die Flammensperre F, welche aus einem nicht-brennbaren Isoliermaterial besteht, besitzt eine Vielzahl von Durchgangskanälen 3, welche die Belüftungskanäle K in den Platten P oberhalb und unterhalb der Flammensperre F verbinden. Diese Durchgangskanäle 3 sind vorzugsweise etwa gleich dimensioniert wie die Belüftungskanäle K in den Platten P und ferner vorzugsweise auch gleich gerichtet wie diese, also unter 45 Grad zur Vertikalen, oder auch vertikal.The insulating facade is divided between the ground and upper floors of the building by a horizontal, beam-shaped flame arrester F into two
In den Durchgangskanälen 3 sind je zwei dünne Brandschutzplatten 4 aus einem feuerfesten, unter Hitzeeinwirkung aufschäumenden Material angeordnet. Im Brandfall schäumen diese Brandschutzplatten 4 auf und verschließen dadurch, wie Fig. 4 zeigt, die Durchgangskanäle 3 in der Flammensperre F. Dadurch wird die sonst bei Bränden in den Belüftungskanälen auftretende Kaminwirkung unterbrochen und der Brandherd eingedämmt.In the
Die Anzahl und Anordnung der Brandschutzplatten 4 in den Durchgangskanälen 3 ist zweitrangig. Wichtig ist vor allem, daß die Art der Brandschutzplatten 4 und die Dimen sion der Durchgangskanäle 3 so aufeinander abgestimmt sind, daß im Brandfall die Querschnittsfläche der einzelnen Durchgangskanäle um wenigstens 80% reduziert wird. Vorzugsweise werden die Durchgangskanäle 3 praktisch vollständig verstopft (Reduktion um 100%).The number and arrangement of the
Die Brandschutzplatten 4 bestehen beispielsweise aus einem wasserhaltigen Natriumsilikat mit geringen Mengen organischer Zusätze. Sie können mit Glasfasern oder Drähten mechanisch verstärkt und mit Epoxiharz beschichtet sein. Eine geeignete Brandschutzplatte dieser Art wird z.B. unter der Markenbezeichnung "PALUSOL" von der Firma BASF, D-6700 Ludwigshafen am Rhein, angeboten.The
Als Material für die balkenförmige Flammensperre F können z.B. schwer entflammbares Polyurethan, Kork, Glaswolle, Perlit, kunstharzgebundene Glasfaserplatten, Asbestfaserplatten oder Formglas (geschäumtes Wasserglas) wie oben erwähnt verwendet werden.As a material for the beam-shaped flame arrester F, e.g. flame retardant polyurethane, cork, glass wool, perlite, synthetic resin-bonded glass fiber plates, asbestos fiber plates or molded glass (foamed water glass) can be used as mentioned above.
Die Anzahl der Flammensperren F in der Isolierfassade richtet sich nach deren Höhe. In der Regel sollte sich jeweils zwischen zwei Geschoßen eine Flammensperre befinden. In besonderen Fällen können natürlich auch in der ganzen Fassade mehr oder weniger Flammensperren vorgesehen sein.The number of flame arresters F in the insulating facade depends on their height. As a rule, there should be a flame arrester between two floors. In special cases, more or less flame arresters can of course also be provided in the entire facade.
Die Brandschutzplatten 4 können in den Durchgangskanälen 3 auf verschiedene Weise angeordnet sein. Eine besonders montagegünstige Variante ist in Figuren 5 und 6 dargestellt. Hier liegen sämtliche Brandschutzplatten in Form von zwei langen Streifen 5 und 6 vor, die sich durch die gesamte Flammensperre erstrecken. Die Brandschutzstreifen 5 und 6 können dabei aufgrund der Nachgiebigkeit des Materials, aus dem die Flammensperre besteht, einfach der Länge nach in dieses eingesteckt oder eingelegt werden.The
Selbstverständlich können für diese Streifen oder Platten auch Aussparungen insbesondere in der Innenwand der Durchgangskanäle nahe der Trennfuge zwischen Flammensperre und Schaumstoffplatten vorgesehen werden.Of course, cutouts can also be provided for these strips or plates, in particular in the inner wall of the through-channels near the joint between the flame arrester and the foam plates.
Vorzugsweise sind die Brandschutzplatten in eine dünne Folie, z.B. aus Aluminium eingehüllt, das gut wärmeleitend ist und ein Quellen des Brandschutzmaterials bei Erreichen der kritischen Temperatur nicht behindert.Preferably the fire protection panels are in a thin film e.g. made of aluminum, which is a good heat conductor and does not prevent the fire protection material from swelling when the critical temperature is reached.
Das Isoliermaterial der Fassadenisolätion kann sowohl wärme- als auch schalldämmend wirken.The insulation material of the facade insulation can have both heat and sound insulation.
Die in den Figuren 7 und 8 gezeigte Ausführungsform der Flammensperre nach der Erfindung besteht aus zwei Balkenhälften F₁ und F₂, wobei F₁ so auf F₂ aufgepaßt ist, daß die in ihnen befindlichen Durchlaßkanäle 7 und 8 miteinander über eine Öffnung lla in der Trennfuge 11 frei verbunden sind.The embodiment shown in Figures 7 and 8 of the flame arrestor according to the invention consists of two beam halves F₁ and F₂, F₁ is so taken care of F₂ that the
Der Kanal 7 führt in der oberen Balkenhälfte F₁ vor der gemeinsamen Öffnung lla näher an die Frontwand A der Fassade heran und steht durch seine obere Öffnung 7a mit dem unter 45° geneigten Belüftungskanal K₁ des oberen Fassadenbereichs 1 in Freier Verbindung. Ein zu diesem parallel verlaufender Kanal K₁' ist gleichfalls gezeigt.The
In gleicher Weise steht der Durchlaßkanal 8 in der unteren Balkenhälfte F₂ durch seine untere Öffnung 8a mit dem Belüftungskanal K₂ im unteren Fassadenbereich 2 in freier Verbindung. Parallel zum unter 45° geneigten Kanal K₂ ist noch ein weiterer Kanal K₂' gezeigt.In the same way, the
Durch den der Trennfuge 11 benachbarten Endbereich des Kanals 8 und den entsprechenden Bereichen der mit ihm parallelen Durchlaßkanäle der unteren Balkenhälfte F₂ erstreckt sich quer hindurch ein langer Kanal 12, der parallel mit der Fassadenfront A verläuft und dessen Bodenfläche mit 13 bezeichnet ist. In der linken und der rechten Seitenwand weist dieser querverlaufende lange Kanal 12 Ausnehmungen oder Nuten 12a bzw. 12b auf, in die Brandschutzstreifen 9 und 10 eingelegt sind. Jeder dieser Streifen besteht aus einem Kern 9a, lOa und einer Umhüllung 9b, lOb aus Aluminiumfolie, die so lose ist, daß sie ein Expandieren des Kerns durch Schäumen oder Quellen nicht behindert, wenn die Temperatur z.B. in den Kanälen K₂, K₂', usw. und im anschließenden Abschnitt des Durchlaßkanals 8 eine kritische Grenze erreicht, bei der ein Auschäumen oder dergl. der Brandschutzstreifen 9 und 10 eintritt.Through the
