Description

Gebäudewand building wall
Die Erfindung betrifft eine Gebäudewand, insbesondere eine Gebäudeaußen- wand, bestehend aus einer Stützkonstruktion, die zumindest zwei im wesentlichen horizontal ausgerichtete Längsträger und zumindest zwei im wesentlichen vertikal ausgerichtete Querträger aufweist, die in Knotenpunkten miteinander verbunden sind und auf zumindest einer Seite der Längs- und Querträger eine Beplankung aufweist, wobei zwischen den Längs- und Querträgern eine Wär- me- und/oder Schalldämmschicht angeordnet ist.The invention relates to a building wall, in particular a building outer wall, consisting of a support structure which has at least two substantially horizontally oriented longitudinal beams and at least two substantially vertically oriented transverse beams which are connected to one another at nodes and on at least one side of the longitudinal and Cross member has planking, a heat and / or sound insulation layer being arranged between the longitudinal and cross members.
Derartige Gebäudewände sind aus dem Stand der Technik bekannt. In der Regel weisen derartige Gebäudewände eine Stützkonstruktion in Holzbauweise auf. Die Stützkonstruktionen bestehen aus Längs- und Querträgern, wobei in Abhängigkeit der Länge bzw. Höhe der Gebäudewand mehrere Längs- bzw.Building walls of this type are known from the prior art. As a rule, such building walls have a supporting structure in timber construction. The support structures consist of longitudinal and cross beams, with several longitudinal or depending on the length or height of the building wall
Querträger vorgesehen sein können. Im Vergleich zu üblichen Fachwerk- Konstruktionen sind derartige Stützkonstruktionen statisch nicht ausreichend stabil, so dass zumindest eine Beplankung vorgesehen sein muss, die die Stützkonstruktion statisch aussteift. Zwischen den Längs- und/oder Querträgern ist eine Wärme- und/oder Schalldämmschicht vorgesehen. Derartige Wärme- und/oder Schalldämmschichten sind in der Regel nicht geeignet, die statische Stabilität derartiger Gebäudewände zu verbessern, da übliche Wärme- und/oder Schalldämmmaterialien nicht oder nur begrenzt auf Druck bzw. Zug belastbar sind. Da die Regelquerschnitte der Holzkonstruktionen im Bereich von ca. 8 bis 10 cm liegen, ist die zwischen dieser Beplankung angeordneteCross members can be provided. Compared to conventional truss constructions, such support structures are not sufficiently stable statically, so that at least one planking must be provided which stiffens the support structure statically. A heat and / or sound insulation layer is provided between the longitudinal and / or cross members. Such thermal and / or soundproofing layers are generally not suitable for improving the static stability of such building walls, since conventional thermal and / or soundproofing materials are not or only to a limited extent able to withstand pressure or tension. Since the regular cross-sections of the wooden structures are in the range of approx. 8 to 10 cm, the one between these planks is arranged
Wärme- und/oder Schalldämmschicht in der Regel nicht ausreichend, um die erforderlichen Schalldämmwerte bzw. den erforderlichen Warmedurchiasswi- derstand zu erreichen.The heat and / or sound insulation layer is generally not sufficient to achieve the required sound insulation values or the required heat resistance.
Ausgehend von diesem Stand der Technik liegt der Erfindung die A u f g a b e zugrunde, eine gattungsgemässe Gebäudewand hinsichtlich ihrer Feuchteresistenz, Schalldämmwerte sowie Sicherheit gegen Schädlinge und hinsichtlich ih- res Wärmedurchlasswiderstandes zu verbessern und gleichzeitig den konstruktiven Aufbau einer derartigen Gebäudewand hinsichtlich seiner Verarbeitung zu vereinfachen.On the basis of this prior art, the invention is based on the task of providing a building wall of the generic type with regard to its moisture resistance, sound insulation values and security against pests and with regard to its Res improve thermal resistance and at the same time simplify the construction of such a building wall in terms of its processing.
Zur L ö s u n g dieser Aufgabenstellung ist vorgesehen, dass unmittelbar auf der außenseitigen Beplankung eine von einer Wärme- und/oder Schalldämmschicht überdeckte wasserableitende und diffusionsoffene Schicht , insbesondere in Form einer Folie angeordnet ist.To solve this problem, it is provided that a water-draining and diffusion-open layer, in particular in the form of a film, is arranged directly on the outside planking and is covered by a heat and / or sound insulation layer.
Demzufolge weist die erfindungsgemässe Ausgestaltung einer gattungsgemä- ssen Gebäudewand eine zusätzliche Wärme- und/oder Schalldämmschicht auf, die unter Zwischenlage einer wasserableitenden und diffusionsoffenen Schicht auf der außenseitigen Beplankung angeordnet ist. Diese wasserableitende und diffusionsoffene Schicht, die vorzugsweise als Folie ausgebildet ist, schützt die Stützkonstruktion, d. h. die Längs- und Querträger vor dem Übertritt vonAccordingly, the inventive design of a generic building wall has an additional heat and / or soundproofing layer, which is arranged on the outside planking with the interposition of a water-draining and diffusion-open layer. This water-draining and permeable layer, which is preferably designed as a film, protects the support structure, i. H. the longitudinal and cross members before crossing
Feuchtigkeit und Holzschädlingen. Hierdurch wird zum einen der Vorteil erzielt, dass die hölzerne Stützkonstruktion langlebig ist. Zum anderen besteht der Vorteil, dass auf umfangreiche Imprägnierungsmaßnahmen seitens der hölzernen Stützkonstruktion nach DIN 68800 verzichtet werden kann. Die Anordnung der wasserableitenden und diffusionsoffenen Schicht direkt auf der Beplankung hat den Vorteil, dass die wasserableitende und diffusionsoffene Schicht im wesentlichen vor Beschädigungen, beispielweise bei der Montage der Gebäudewand durch Anker oder dergleichen geschützt ist. Hierdurch entfallen aufwendige Befestigungsmaßnahmen der Folie, bei sonst üblicher Anordnung auf der Oberfläche der zusätzlichen Außendämmung. Ferner kann die wasserableitende und ^iffusionsoffene Schicht bereits werksseitig auf großflächigen Beplankungen vorgesehen sein, so dass bei der Montage αer Gebäudewand lediglich die Stoßbereiche aufeinanderstoßender Beplankungsplatten ergänzend mit einer wasserableitenden und diffusionsoffenen Folie abgedeckt oder überlap- pend abgedichtet werden müssen. Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Schicht eine diffusionsäquivalente Luftschichtdicke SD < 0,5 m, insbesondere < 0,2 m aufweist. Bei diesen Werten wird ein zuverlässiger Schutz der Stützkonstruktion, aber auch der Beplankung, die ebenfalls aus Holzwerkstoffen bestehen kann, erzielt.Moisture and wood pests. On the one hand, this has the advantage that the wooden support structure is durable. On the other hand, there is the advantage that extensive impregnation measures on the part of the wooden support structure according to DIN 68800 can be dispensed with. The arrangement of the water-draining and diffusion-open layer directly on the cladding has the advantage that the water-draining and diffusion-open layer is essentially protected from damage, for example when anchoring the building wall or the like. This eliminates the need for complex fastening measures for the film, with the usual arrangement on the surface of the additional external insulation. Furthermore, the water-draining and open-fusion layer can already be provided in the factory on large-area cladding, so that when installing the building wall, only the joint areas of cladding cladding panels must be additionally covered with a water-draining and diffusion-open film or overlap-sealed. According to a further feature of the invention, it is provided that the layer has a diffusion-equivalent air layer thickness S D <0.5 m, in particular <0.2 m. With these values, reliable protection of the support structure, but also the planking, which can also consist of wood-based materials, is achieved.
Vorzugsweise weist die Stützkonstruktion beidseitig eine Beplankung auf, so dass die erste Wärme- und/oder Schalldämmschicht vollständig in der Gebäudewand eingeschlossen ist. Die Gebäudewand kann hierbei aus einzeln aufzu- stellenden Elementen bestehen, die jeweils eine Stützkonstruktion und zweiThe support structure preferably has planking on both sides, so that the first heat and / or sound insulation layer is completely enclosed in the building wall. The building wall can consist of elements to be set up individually, each with a supporting structure and two
Beplankungen mit dazwischen angeordneter Wärme- und/oder Schalldämmschicht aufweisen. Alternativ kann vorgesehen sein, dass die Gebäudewand baustellenseitig aus ihren Einzelbestandteilen aufgebaut wird. Im Zuge des zunehmenden Fertighausbaus ist allerdings die erstgenannte Ausgestaltung der Gebäudewand von besonderer wirtschaftlicher Bedeutung.Have planking with a heat and / or sound insulation layer arranged in between. Alternatively, it can be provided that the building wall is constructed from its individual components on the construction site. In the course of increasing prefabricated house construction, however, the first-mentioned design of the building wall is of particular economic importance.
Aus optischen Gründen und zum Schutz gegen Witterungseinflüsse und Beschädigungen kann vor der außenseitigen Beplankung eine Außenschale, insbesondere in Form eines Mauerwerks angeordnet sein. Dieses Mauerwerk kann beispielsweise mit einer äußeren Putzschicht versehen sein. Demzufolge ist die auf der wasserableitenden und diffusionsoffenen Schicht angeordnete Wärme- und/oder Schalldämmschicht von der Außenschale abgedeckt. Die Außenschale kann im Abstand von der Wärme- und/oder Schalldämmschicht angeordnet sein, um einen Luftspalt zu bilden, über den Feuchtigkeit abgeführt werden kann. Der Abstand zwischen der Außenschale und der Wärme- und/oder SchaNr'ämmsπhicht beträgt weniger als 10 cm insbesondere weniger als 6 cm und weist eine Größe von zumindest 2 cm auf. Vorzugsweise ist der Abstand zwischen der Außenschale und der Wärme- und/oder Schalldämmschicht somit zwischen 2 und 6 cm groß. Die Verbindung der Außenschale mit der außenseitigen Beplankung erfolgt über Distanzelemente, die mit der außenseitigen Beplankung verbunden sind und die Wärme- und/oder Schalldämmschicht durchgreifen. Hierbei hat es sich als vorteilhaft erwiesen, die wasserableitende und diffusionsoffene Schicht direkt auf der Beplankung zu befestigen. Insbesondere ist ein Verkleben dieser Schicht auf der Beplankung vorteilhaft. Die Verklebung kann sowohl voll- als auch teilflächig erfolgen und werksseitig durchgeführt werden. Hierdurch wird eine Beschädigung dieser wasserableitenden und diffusionsoffenen Schicht während des üblichen Auf- mauerns der Außenschale und deren Verankerung auf der Dämmschicht bzw. auf der Beplankung, beispielsweise durch durchzuführende Anker, aber auch insbesondere bei der Korrektur der zutreffenden Anordnung der wasserableitenden und diffusionsoffenen Schicht verhindert. Ferner lässt sich durch die konstruktive Ausgestaltung der erfindungsgemäßen Gebäudewand ein schnellerer Baufortschritt erzielen, was die Wirtschaftlichkeit einer derartigen Gebäudewand gegenüber dem Stand der Technik wesentlich verbessert.For visual reasons and to protect against weather influences and damage, an outer shell, in particular in the form of masonry, can be arranged in front of the outside planking. This masonry can be provided with an outer layer of plaster, for example. Accordingly, the heat and / or soundproofing layer arranged on the water-draining and diffusion-open layer is covered by the outer shell. The outer shell can be arranged at a distance from the heat and / or sound insulation layer in order to form an air gap through which moisture can be removed. The distance between the outer shell and the heat and / or heat insulation layer is less than 10 cm, in particular less than 6 cm, and has a size of at least 2 cm. The distance between the outer shell and the heat and / or sound insulation layer is thus preferably between 2 and 6 cm. The outer shell is connected to the outside planking by means of spacer elements which are connected to the outside planking and penetrate the heat and / or sound insulation layer. It has proven to be advantageous here water-draining and vapor-permeable layer to be attached directly to the planking. In particular, it is advantageous to glue this layer to the planking. The gluing can take place over the full or partial area and can be carried out in the factory. This prevents damage to this water-draining and diffusion-open layer during the usual bricking up of the outer shell and its anchoring on the insulation layer or on the planking, for example by anchors to be carried out, but also in particular when correcting the correct arrangement of the water-draining and diffusion-open layer. Furthermore, the constructional design of the building wall according to the invention enables faster construction progress, which significantly improves the economy of such a building wall compared to the prior art.
Die Beplankung besteht aus statisch wirksamen Elementen. Insbesondere sind hierzu Vollhölzer, Holzwerkstoffe in Form von kunstharz- oder zementgebundenen Spanplatten, Platten aus Porenleichtbeton, Gipskarton und/oder Gipsfaserplatten geeignet. Als Wärme- und/oder Schalldämmschicht sind Mineralfaserprodukte, insbesondere Steinwolleprodukte vorgesehen.The planking consists of statically effective elements. Solid wood, wood-based materials in the form of resin-bonded or cement-bonded chipboard, panels made of lightweight porous concrete, plasterboard and / or gypsum fibreboard are particularly suitable for this purpose. Mineral fiber products, in particular rock wool products, are provided as the heat and / or sound insulation layer.
Schließlich ist nach einem weiteren Merkmal der Erfindung vorgesehen, dass zwischen der innenseitigen, vornehmlich der raumseitigen Beplankung und der Stützkonstruktion eine windsperrende und insbesondere dampfbremsende Schicht in Form einer Folie, Pappe und/oder eines Papiers angeordnet ist. Diese dampfbremsende Schicht verhindert das Ein- und Ausströmen von Luft durch die Wandkonstruktion und somit Energieverlust sowie Tauwasser-Finally, it is provided according to a further feature of the invention that a wind-blocking and in particular vapor-retarding layer in the form of a film, cardboard and / or paper is arranged between the inside planking, primarily the room-side planking, and the support structure. This vapor retardant layer prevents air from flowing in and out through the wall construction and thus energy loss and condensation

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, in der eine bevorzugte Ausführungsform einer erfindungsgemäßen Gebäudewand dargestellt ist. Die Gebäudewand besteht aus einer Stützkonstruktion 1 , die nicht näher dargestellte, vertikal verlaufende Querträger sowie mit den Querträgern an Knotenpunkten verbundene, horizontal ausgerichtete Längsträger 2 aus Holz aufweist. Zwischen den Längsträgern 2 ist eine Wärme- und Schalldämmschicht 3 aus Steinwolle angeordnet, die den Raum zwischen den Längsträgern 2 und den flankierenden Querträgern ausfüllt.Further features and advantages of the invention result from the following description of the associated drawing, in which a preferred embodiment of a building wall according to the invention is shown. The building wall consists of a support structure 1, which has vertical cross members (not shown in detail) and horizontally oriented wooden longitudinal members 2 connected to the cross members at nodes. Between the side members 2, a heat and sound insulation layer 3 made of rock wool is arranged, which fills the space between the side members 2 and the flanking cross members.
Die Stützkonstruktion 1 ist beidseitig mit einer Beplankung aus Holzplatten voll- flächig abgedeckt. Die Beplankung besteht aus einer inneren Beplankung 4 und einer äußeren Beplankung 5, wobei die äußere Beplankung 5 direkt auf den Längsträgern 2 und den nicht näher dargestellten Querträgern der Stützkonstruktion 1 aufgebracht ist, während die innere Beplankung 4 unter Zwischenlage einer windsperrenden und dampfbremsenden Schicht 6, bestehend aus einer Folie auf den Längsträgern 2 und den nicht näher dargestellten Querträgern der Stützkonstruktion 1 befestigt ist.The support structure 1 is covered on both sides with a covering made of wooden panels. The planking consists of an inner planking 4 and an outer planking 5, the outer planking 5 being applied directly to the longitudinal beams 2 and the cross beams of the supporting structure 1, which are not shown in detail, while the inner planking 4 with the interposition of a wind-blocking and vapor-blocking layer 6, consisting of a film is attached to the longitudinal beams 2 and the cross beams, not shown, of the support structure 1.
Die Stützkonstruktion 1 bildet zusammen mit der inneren und der äußeren Beplankung 4 bzw. 5 eine statisch stabile Gebäudewand.The support structure 1 forms, together with the inner and outer cladding 4 and 5, a statically stable building wall.
Direkt auf die äußere Beplankung 5 ist eine wasserableitende und diffusionsoffene Schicht 7 mit einer diffusionsäquivalenten Luftschichtdicke SD von 0,15 m aufgebracht. Diese wasserableitende und diffusionsoffene Schicht 7 ist auf die äußere Beplankung 5 befestigt bzw. aufgeklebt, wobei die Klebeschicht teilflächig ausgebildet ist. Als wasserableitende und diffusionsoffene Schicht 7 ist eine Kunststofffolie vorgesehen.A water-draining and diffusion-open layer 7 with a diffusion-equivalent air layer thickness S D of 0.15 m is applied directly to the outer planking 5. This water-draining and diffusion-open layer 7 is attached or glued to the outer planking 5, the adhesive layer being partially formed. A plastic film is provided as the water-draining and permeable layer 7.
Auf die wasserableitende und diffusionsoffene Schicht isi wiederum eine Wärme- und Schalldämmschicht 8 in Form von Steinwolleplatten aufgebracht. Die Steinwolleplatten können auf die wasserableitende und diffusionsoffene Schicht 7 aufgeklebt oder in anderer Weise befestigt sein. Beispielsweise können hierzu auch Profilelemente vorgesehen sein, die mit der äußeren Beplankung 5 verschraubt und in die Steinwolleplatten eingreifend ausgebildet sind. Die Wärme- und Schalldämmschicht 8 wird von einer Vielzahl von Distanzelementen 9 durchgriffen, welche eine Außenschale in Form eines Mauerwerkes mit der äußeren Beplankung 5 verbinden. In turn, a heat and sound insulation layer 8 in the form of stone wool panels is applied to the water-draining and permeable layer. The rock wool panels can be glued to the water-draining and permeable layer 7 or attached in some other way. For example, profile elements can also be provided for this purpose, which are screwed to the outer planking 5 and are designed to engage in the rock wool panels. The heat and sound insulation layer 8 is penetrated by a large number of spacer elements 9, which connect an outer shell in the form of masonry to the outer paneling 5.
