Description
Die Erfindung betrifft eine Anordnung zum Dämmen und Dichten von
Fugen aufweisenden Bauwerksfassaden der im Oberbegriff des Anspruchs
1 angegebenen Art.The invention relates to an arrangement for insulating and sealing
Building facades showing joints in the preamble of the
Eine derartige Anordnung ist aus der FR-A-2 378 152 bekannt. Sie umfaßt einen Mehrschichtenaufbau mit einer gummielastischen Bahn, die mit Kleber mit Verbund auf dem Untergrund aufgeklebt wird. Der Oberflächenaufbau besteht aus einer Spachtelschicht, Gewebelage und Putzschicht und ist auf der Oberfläche der gummielastischen Bahn aufgetragen.Such an arrangement is known from FR-A-2 378 152. she comprises a multilayer structure with a rubber-elastic web, which is glued to the surface with a composite adhesive. The surface structure consists of a filler layer, Fabric layer and plaster layer and is on the surface of the rubber elastic Path applied.
Diese Anordnung ist fugenüberbrückend und verkraftet Fugenverschiebungen bis zu 15 mm. Dies wird durch die direkt auf den Untergrund vollflächig aufgeklebte elastische Folie bewirkt.This arrangement bridges the joints and copes with joint displacements up to 15 mm. This is directly due to the Elastic foil fully adhered to the surface.
Die Anordnung schützt gegen Feuchtigkeit und Hitze, ist aber selbst keine Wärmedämmung, wobei sie allerdings einen zusätzlichen Beitrag zur Wärmedämmung leistet. Nachteilig an der elastischen Anordnung ist die sich durch eine Fugenverschiebung aufbauende Rückstellkraft bzw. Spannung. Diese Spannung führt auf Dauer zum Ablösen der gummielastischen Bahn oder zu einer beschleunigten Alterung des unter Spannung stehenden Materials, so daß dies nur eine zeitlich begrenzte Lösung darstellt.The arrangement protects against moisture and heat, but is no thermal insulation itself, although it does provide an additional one Contributes to thermal insulation. A disadvantage of the elastic The arrangement is that which is built up by a movement of the joint Restoring force or tension. This tension leads to Duration to detach the rubber elastic web or to accelerate Aging of the live material, see above that this is only a temporary solution.
In der FR-A-2 394 651 ist eine Anordnung zur Überbrückung von Fugen oder Rissen beschrieben. Diese Anordnung ist ein Komplexband, d. h. ein Stoffstreifen, unter den ein Plastikband geklebt ist. Das Plastikband kann einen Riß abdecken. Der Stoffstreifen wird in die Deckschicht, den Putz, eingesetzt, um den Putz am Plastikband zu halten.In FR-A-2 394 651 there is an arrangement for bridging Joints or cracks described. This arrangement is a complex band, d. H. a strip of cloth with a plastic tape stuck under it is. The plastic tape can cover a tear. The strip of fabric is used in the top layer, the plaster, to the plaster on To hold plastic tape.
Dieses Komplexband wird auf den Fugenbereich aufgebracht und durch einen biegsamen Belag stabilisiert. Dieses Band dient somit nur der Überbrückung von Fugen bzw. Rissen, wobei bei einer erneuten Fugenverschiebung wiederum Risse in der Riß- bzw. Fugenabdeckung entstehen können.This complex tape is applied to the joint area and stabilized by a flexible covering. This tape thus serves only the bridging of joints or cracks, with one renewed joint displacement again cracks in the crack or Joint cover can arise.
Es besteht ein Bedarf aus Fertigplatten erstellte Bauwerksfassaden zu sanieren, da sie zum großen Teil heutzutage nicht mehr die Erfordernisse an die Wärmedämmung erfüllen. Ein weiteres Problem betrifft den unzureichenden Feuchteschutz. Außerdem erfüllen solche Bauwerksfassaden nicht mehr aktuelle ästhetische Ansprüche.There is a need for prefabricated building facades to renovate as they are no longer in large part today meet the requirements for thermal insulation. Another one The problem concerns insufficient moisture protection. Furthermore such building facades no longer meet current aesthetic requirements Expectations.
Ein wesentlicher Bedarf für die Sanierung der in Rede stehenden Bauwerks fassaden betrifft den Bauwerksfugenbereich, der erfahrungsgemäß nicht nur durch Witterungseinflüsse stark beeinträchtigt ist, sondern auch den immer wieder auftretenden Verformungen der Fassadenplatten nicht mehr schadfrei folgen kann. Risse in den Fugendichtungen, Ablösungen, Wassereintritt in die Konstruktion und in die Dämmschicht sind die Folgen.An essential need for the redevelopment of the in question Building facades affects the area of the building joints, which experience has shown not only badly affected by the weather but also the constantly occurring deformations the facade panels can no longer follow without damage. Cracks in the joint seals, detachments, water ingress into the construction and in the insulation layer are the consequences.
Ferner ist es bekannt, Fugen aufweisende Bauwerksfassaden zu sanieren, oder nachträglich zu dämmen mittels einer Dämm-Deckschichtstruktur, sogenannte Vollwärmeschutz-Systemen. Diese herkömmliche Struktur umfaßt eine außenliegende, wasserundurchlässige Deckschicht aus beispielsweise Außenputz, der gegebenenfalls mit einem geeigneten Gewebe armiert ist und eine Dämmschicht, die vorzugsweise aus einer Dämmplatte besteht und mit dem darunter liegenden Plattenmaterial der Fassade fest verbunden, beispielsweise verklebt ist. Bei dieser herkömmlichen Anordnung wird die ursprüngliche Fugenstruktur der Bauwerksfassade auf die Dämmdeckschichtstruktur übertragen. Mit anderen Worten ist die Dämmdeckschichtstruktur an denselben Stellen miteinander verfugt wie die darunter liegende Bauwerksfassade, wobei als Verfugungsmaterial beispielsweise ein elastomeres Material zum Einsatz kommt.It is also known to have building facades with joints renovate or subsequently insulate using an insulation top layer structure, so-called full heat protection systems. This conventional structure includes an external, waterproof top layer made of, for example, external plaster, which is optionally reinforced with a suitable fabric and an insulation layer, which preferably consists of an insulation board and with the underlying plate material of the facade connected, for example glued. With this conventional The arrangement is the original joint structure of the Building facade transferred to the insulation top layer structure. With in other words, the insulation cover layer structure is on the same Jointed together like the one below Building facade, with a elastomeric material is used.
Das Übernehmen der Fugen in die Dämm-Deckschichtstruktur ist aufwendig und bedarf besonderer Sorgfalt bei der Ausführung.The joints are transferred to the insulation top layer structure complex and requires special care during execution.
Diese herkömmliche Dämm-Deckschichtstruktur zur Sanierung von Bauwerksfassaden weist u.a. den Nachteil auf, daß der ursprüngliche, nicht mehr zeitgemäße ästhetische Eindruck einer plattenartig zusammengesetzten Bauwerksfassade auch nach der Sanierung erhalten bleibt. Ein in technischer Hinsicht gravierender Nachteil besteht darin, daß die Fugen in der Dämm-Deckschichtstruktur zumindest auf längere Sicht Dichtigkeitsprobleme verursachen, da die Dichtstoffe auch nach einer derartigen Sanierung der Sonne und der Atmosphäre ausgesetzt sind und zum Verspröden, Reißen und Undichtwerden neigen. Mit anderen Worten ist die herkömmliche Dämm-Deckschichtstruktur nicht dauerhaft feuchtigkeitsdicht und bedarf damit binnen absehbarer Zeit einer Nachbesserung.This conventional insulation top layer structure for the renovation of Building facades shows the disadvantage that the original, outdated aesthetic impression of a plate-like composite building facade even after renovation preserved. A technically serious one The disadvantage is that the joints in the insulation top layer structure at least in the long run tightness problems cause, as the sealants even after such Renovation of the sun and the atmosphere are exposed to and Embrittlement, tearing and leakage tend. In other words the conventional insulation top layer structure is not permanent moisture-proof and will therefore need one within the foreseeable future Rectification.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Anordnung zum Dämmen von Fugen aufweisenden Bauwerksfassaden der eingangs genannten Art zu schaffen, die neben einer guten Wärmedämmung auch langfristig eine sichere Dichtungsfunktion gewährleistet und einen annehmbaren ästhetischen Eindruck vermittelt.The object of the present invention is a Arrangement for insulating joints of building facades to create the kind mentioned above, in addition to a good Thermal insulation also provides a reliable sealing function in the long term guaranteed and an acceptable aesthetic impression mediated.
Gelöst wird diese Aufgabe durch eine Anordnung zum Dämmen und
Dichten von Bauwerksfugen mit den Merkmalen des Anspruchs 1.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen
angegeben.This task is solved by an arrangement for insulation and
Sealing structural joints with the features of
Durch einen schubweichen Entkopplungsbereich der Dämmschicht von vorbestimmter Breite im Bereich der Bauwerksfugen wird eine fugenfreie Dämm-Deckschichtstruktur vorgesehen, die mangels Fugenbereiche nahezu ideal feuchtigkeitsdicht ist und damit eine dauerhafte Sanierung von Fugen aufweisenden Bauwerksfassaden gewährleistet. Ein weiterer Vorteil der erfindungsgemäßen fugenfreien Dämm-Deckschichtstruktur besteht in der positiven ästhetischen Wirkung der damit sanierten Bauwerksfassade.Through a flexible decoupling area of the insulation layer from a predetermined width in the area of the structural joints is one joint-free insulation top layer structure provided, the lack Joint areas is almost ideally moisture-proof and therefore a permanent renovation of building facades with joints guaranteed. Another advantage of the joint-free according to the invention Insulation top layer structure consists in the positive aesthetic Effect of the building facade thus renovated.
Wie eingangs angesprochen, besteht ein grundlegendes Problem bei der Sanierung von Fugen aufweisenden Bauwerksfassaden in den Fugenbereichen, da die Bauwerksfassaden in diesen Bereichen "arbeiten", d.h. sich immer wieder bewegen. Während die dabei auftretenden Verformungen bei den Fugen aufweisenden Bauwerksfassaden das Fugenmaterial selbst langfristig zerstören oder abreißen lassen, ist es erforderlich, bei der erfindungsgemäß fugenlos ausgeführten Dämm-Deckschichtstruktur Maßnahmen zu ergreifen, damit die Verformungen des Untergrundes die fugenlose Dämm-Deckschichtstruktur nicht beschädigen. Würden derartige Maßnahmen nicht getroffen, so ist damit zu rechnen, daß aufgrund von Untergrund-Verformungen in der Deckschicht Risse ausgebildet werden, so daß dann die Dichtungsfunktion der fugenfreien Dämm-Deckschichtstruktur nicht mehr gewährleistet ist. Eine solche sichere Dichtungsfunktion ist aber für die Wärmedämmung und darüber hinaus, insbesondere für spezielle Untergründe mit unzureichender Feuchtebeständigkeit unbedingt erforderlich, wie Betone, die durch Alkalisilikat- und Ettringit-Reaktion gefährdet sind. Durch den schubweichen Entkopplungsbereich der Dämmschicht werden im Bereich der Bauwerksfugen auftretende Verformungen ohne Beschädigung von der Dämm-Deckschichtstruktur aufgenommen. Beschädigungsgefährdet ist insbesondere die grundsätzlich relativ dünn ausgebildete Deckschicht der Struktur, der auch die Dichtungsfunktion zukommt.As mentioned at the beginning, there is a fundamental problem with the renovation of building facades with joints in the Joint areas, since the building facades in these areas "work", i.e. keep moving. While they are there deformations occurring in the building facades with joints destroy the joint material itself in the long term or can tear off, it is necessary in the invention jointly executed insulation cover layer structure seize so that the deformations of the subsurface the seamless Do not damage the insulation cover layer structure. Would such Measures not taken, it can be expected that due to cracks are formed in the surface layer due to substrate deformations so that the sealing function of the joint-free insulation cover layer structure is no longer guaranteed. Such safe sealing function is for thermal insulation and in addition, especially for special substrates with insufficient moisture resistance absolutely necessary, such as Concrete endangered by alkali silicate and ettringite reaction are. Due to the flexible decoupling area of the insulation layer deformations occurring in the area of structural joints without Damage absorbed by the insulation top layer structure. In particular, the risk of damage is basically relative thinly formed top layer of the structure, which also the sealing function comes to.
Durch die erfindungsgemäße Dämm-Deckschichtstruktur werden Verformungsspitzen von der Außenhaut und der Deckschicht abgehalten oder auf ein ungefährliches Maß verteilt. Zusätzlich kann die Außenhaut der Struktur selbst derart elastisch gebildet werden, daß diese auch partiell erhöhten Verformungen zu widerstehen vermag, ohne daß es zu einer Rißausbildung kommt.The insulation top layer structure according to the invention causes deformation peaks kept from the outer skin and the top layer or distributed to a non-dangerous level. In addition, the Outer skin of the structure itself is formed so elastically, that they can withstand even partially increased deformations is able to develop without crack formation.
Der schubweiche Bereich erstreckt sich vorteilhafterweise beidseits jeder Bauwerksfuge über einen vorbestimmten Bereich. Außerhalb dieses Bereichs kann die Dämmschicht der Struktur in herkömmlicher Weise fest mit dem Untergrund verbunden sein.The thrust-soft area advantageously extends on both sides each building joint over a predetermined area. Outside the insulation layer of the structure in this area conventionally be firmly connected to the ground.
Der schubweiche Verbundbereich ist vorteilhafterweise realisiert
als eine weiche Klebstoffschicht. Alternativ hierzu kann eine
dauerplastische Klebstoffschicht vorgesehen sein oder ein
schubweicher Verbundmörtel, durch welchen die Dämmschicht mit dem
Untergrund, also der Bauwerksfassade verbunden ist.
Schließlich kommt als schubweicher Verbundbereich auch eine
Elastomerschicht in Betracht. Gegebenenfalls ist der schubweiche
Verbundbereich faserbewehrt. The shear-soft composite area is advantageously implemented as a soft adhesive layer. Alternatively, a permanently plastic adhesive layer can be provided or a shear-soft composite mortar, through which the insulation layer is connected to the substrate, that is to say the building facade.
Finally, an elastomer layer can also be considered as a shear-soft composite area. The shear-soft composite area may be fiber-reinforced.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung
ist vorgesehen, die Dämmschicht mehrlagig auszubilden und die
einzelnen Lagen im Bereich der Bauwerksfugen mit schubweichen
Verbindungszonen vorzusehen, wobei als schubweiches Material das
vorstehend genannte Material, also beispielsweise eine
dauerplastische Klebstoffschicht, in Betracht kommt.
Die Maßnahmen zur gleichmäßigen Verteilung der Untergrund-Verformungen
können auch darin bestehen, daß innerhalb der
Dämmschicht Entkopplungsbereiche vorgesehen sind, die als
verbundfreie Zonen oder als schubweiche Zonen im Bereich der
Bauwerksfugen ausgebildet sind.According to a further preferred embodiment of the invention, it is provided that the insulation layer has a multilayer structure and that the individual layers in the area of the structural joints have flexible connection zones, the material mentioned above, for example a permanently plastic adhesive layer, being considered as flexible material.
The measures for uniform distribution of the substrate deformations can also consist in providing decoupling areas within the insulation layer, which are designed as bondless zones or as shear-soft zones in the area of the structural joints.
Wie bereits vorstehend erwähnt, können die Maßnahmen zur zerstörungsfreien Aufnahme der Untergrundverformungen durch die erfindungsgemäße Dämm-Deckschichtstruktur auch in deren Außenhaut, also in der Deckschicht selbst, vorgesehen sein. Bevorzugt ist dabei die Verwendung eines besonders dehnfähigen Deckschichtabschnitts im Bereich der Bauwerksfugen. In Betracht kommt dabei beispielsweise ein elastomeres Material, das gegebenenfalls faser- oder mattenbewehrt ist.As already mentioned above, the measures for non-destructive absorption of the substrate deformation by the insulation top layer structure according to the invention also in the outer skin thereof, that is, be provided in the cover layer itself. Prefers is the use of a particularly stretchable cover layer section in the area of structural joints. This comes into consideration for example an elastomeric material, which if necessary is fiber or mat reinforced.
Schließlich können in besonders kritischen Strukturen die vorstehend genannten Maßnahmen mit Bezug auf die Deckschicht und die Dämmschicht der Dämm-Deckschichtstruktur auch in vorteilhafter Weise miteinander kombiniert sein.Finally, in particularly critical structures measures mentioned above with regard to the top layer and the insulation layer of the insulation top layer structure also advantageous Wise combined with each other.

Als Material für den besonders dehnfähigen Bereich 8 kommt z.B. ein Elastomer in Betracht.In Fig. 3, the outer skin or the outer layer is the insulating cover layer structure formed 8 1 elastically, at least in a portion of the total width l o opposite to the Bauwerksfuge 4. This area 8 is specially adapted stretchable and preferably mat or fiber-reinforced. An elastomer, for example, can be considered as the material for the particularly stretchable region 8.
In Fig. 3 ist die unter der Außenhaut 8 liegende Dämmschicht oder
Dämmplatte 3 fest mit dem Betonuntergrund 5 verklebt, und zwar
auch im kritischen Bereich der Bauwerksfuge. Alternativ hierzu
kann die Dämmplatte in diesem kritischen Bereich gegenüber dem
Betonuntergrund 5 verbundweich an den Untergrund 5 angekoppelt
sein. Schließlich kann in Fig. 4 anstelle der einzigen Dämmplatte
