Abstract

Curtain wall with a high degree of heat insulation, requirements of a structural and architectonic nature being fulfilled in a largely cost-saving manner, characterised in that the relatively soft material of the heat-insulating shell can assume, in addition to heat insulation, the function of the substructure for the shell exposed to weathering in that force transfer is distributed over larger surface areas in conjunction with the design of the shell exposed to weathering, heat-insulating shell and facade-securing means.

Description

Vorhangfassade mit Hochwärmedämmung Curtain wall with high thermal insulation

Die Erfindung ufaßt ein Baukastensystem zur Herstellung einer Vorhangfassade mit optimalem Wetterschutz, Rißfreiheit, einer Hochwärmedämmung, geringem Gewicht, einfachem Aufbau, verbunden mit einem minimalisierten Montageau.fwand, geeignet für Alt- und Neubauten. The invention ufasst a modular system for the production of a curtain wall with optimal weather protection, freedom from cracks, high thermal insulation, low weight, simple construction, combined with a minimalized mounting wall for old and new buildings.

Die Anforderungen an eine Fassade sind sehr vielfältig. The requirements for a facade are very diverse.

Daraus ergab sich, daß man gezwungen war - innerhalb des Bekannten - Nachteile in Kauf zu nehmen. U. a. seien hier genannt Hohes Gewicht, komplizierter Aufbau, aufwendige Montage, hohe Kosten oder Kompromisse in bezug zu den gewunschten Eigenschaften.The result was that one was forced - within the known - Disadvantages to be accepted. I.a. are mentioned here High weight, more complicated Construction, complex assembly, high costs or compromises in relation to the desired Properties.

Die wichtigsten Anforderungen an eine Fassade sind unter anderen Wasserundurchlässigkeit von außen nach innen. The most important requirements for a facade are among others Water impermeability from the outside in.

Dampfdurchlässigeit von innen nach außen. Vapor permeability from the inside to the outside.

Lange Lebensdauer geringer Wartungsaufwand. Long service life low maintenance.

Gute architektonische Gestaltungsmöglichkeiten. Good architectural design options.

Gute Anpassung an vorbestimmte Höhen und Längen. Good adaptation to predetermined heights and lengths.

Eine gute Wärmedämmung. Good thermal insulation.

Das Ziel, diesen vielfältigen Anforderungen gerecht zu werden, führte zur Aufteilung in Wetterschale und Dämmschale, welche mit der tragenden oder abstützenden Wand zu verbinden waren, d.h. zu mehrschaligen Konstruktionen. The goal of meeting these diverse requirements led for division into a weather shell and an insulating shell, which are connected to the load-bearing or supporting To be connected to the wall, i.e. to form multi-layered structures.

Da optimale Wasserabweisung und Schutz vor Witterungseinflüssen Dampfundurchlässigkeit zur Folge hat, mußte die Wetterschale hinterlüftet werden, d.h. zwischen ärmedämmschale und Wetterschale amide ein belüfteter Luftraum erforderlich. Dies bedingt eine zusätzliche Konstruktion, nur um die Wetterschale in dieser Lage zu fixieren, oder man ist bereit, deshalb auf eine Dampfdurchlässigkeit ganz zu verzichten, ist dann je«uoch gezi'.unger'., ZUsatzlich eine verläßliche Dampfsperre an der Wandinnenseite herzustellen. As optimal water repellency and protection against the effects of the weather, vapor impermeability As a result, the weather shell had to be ventilated from behind, i.e. between the insulating shell and weather shell amide a ventilated air space is required. This requires an additional Construction, just to fix the weather shell in this position, or you are ready therefore towards a vapor permeability renounce is then je "uoch'.unger"., In addition, a reliable vapor barrier on the inside of the wall to manufacture.

Eine aus kleinformatigen Teilen hergestellte Wetterschale erfordert entweder eine bestimmte eigene Standfestigkeit oder eine aufwendige Unterkonstruktion. Die Wärmedämmachale muß in jedem Fall mehr oder weniger oft störend durchbrochen werden. A weather shell made from small-sized parts requires either a certain stability of your own or an elaborate substructure. The thermal insulation roof has to be broken through more or less often in a disruptive manner will.

Großformatige Wetterschalenteile schränken die architektonischen Gestaltungsmöglichkeiten stark ein, die Längen-bzw. Höhenanpassung wird problematisch und die unterschiedlichen Wärmeausdehnungskoeffizienten erfordern zunehmend besondere Maßnahmen. Large-format weather shell parts limit the architectural Design options strongly, the length or. Height adjustment becomes problematic and the different coefficients of thermal expansion require increasingly special ones Measures.

Diese Nachteile werden durch die Erfindung beseitigt, derzufolge der relativ weiche Werkstoff der Wärmedämmschale zusätzlich zur Wärmedämmung die Funktion der Unterkonstruktion für die Wetterschale dadurch übernehmen kann, daß die Kräfteübertragung auf größere Flächen im Zusammenspiel mit der konstfuktiven Ausbildung von Wetterschale und Fassadenhalterung verteilt wird und gleichzeitig die Formgebung der Systemteile bauphysikalische, architektonische, wirtschaftliche und Montageanforderungen weitgehend berücksichtigt. These drawbacks are eliminated by the invention, as a result the relatively soft material of the thermal insulation shell in addition to the thermal insulation Can take over the function of the substructure for the weather shell that the transfer of forces to larger areas in interaction with the constructive Training of weather shell and facade bracket is distributed and at the same time the shaping of the system parts in terms of building physics, architecture and economy and assembly requirements are largely taken into account.

Die Erfindung wird im folgenden an Hand der Zeichnung in der Reihenfolge der Ivlontage näher beschrieben, wodurch gleichzeitig das Zusammenspiel der Einzelelemente im System erkennbar wird. The invention is explained below with reference to the drawing in the order of the Ivlontage described in more detail, whereby at the same time the interaction of the individual elements becomes recognizable in the system.

Auf der vorhandenen tragenden Außenwand - eine besondere Vorbehandlung ist nicht erforderlich - wird das Ealterungsprofil 1 aus einem harten korrosionsfesten bzw. -geschützten Material waagerecht und durchlaufend durch Anschrauben, Anschießen usw. kontrollierbar befestigt. Der nur am Anfang erforderliche untere Abschlußteil 2 ist gleichzeitig als Sturzausbildung verwendbar. On the existing load-bearing outer wall - a special pretreatment is not required - the aging profile 1 is made of a hard, corrosion-resistant one or -protected material horizontally and continuously by screwing and shooting etc. controllably attached. The lower final part, which is only required at the beginning 2 can also be used as lintel training.

Die Montage der Wärmedämmelemente 3 ge8chieht durch einfaches Aufstecken mit den breiten Auflager- und Berührungs flächen 4 in das Halterunesprofil 1 hinein. Die Fixierung des zweiten Halterungsprofils 1 bei (a) erfolgt durch einfaches Auflegen und die Befestigung dieses Profils mit der tragenden Wand kann hergestellt werden. The installation of the thermal insulation elements 3 is done by simply pushing them on with the wide support and contact surfaces 4 in the Halterunesprofil 1 into it. The second mounting profile 1 is fixed at (a) by simply placing it on top and the attachment of this profile to the load-bearing wall can be made.

u:'cn die Wulst und @utensausbildung bei 5 erfolgt so eine iontagesicllerung f-r die erste Reihe der Wärmedämmelemente. u: 'cn the bead and buttock formation at 5, a day-to-day training takes place for the first row of thermal insulation elements.

Now the second row of heat detectors is attached. This series secures the previous one through the clamp effect at 6 finally and off automatically.

Die Anpassung an vorgegebene Bauwerks abmessungen erfolgt durch Verwendung von Wärmedämmelementen 3, welche Teilstücken der Grundgröße entsprechen. Durch Halb- und Fünfachtelelemente wird bereits eine weitgehende Anpassung erzielt ohne die mögliche Teilung bei der Montage. The adaptation to the given building dimensions takes place through use of thermal insulation elements 3, which parts correspond to the basic size. By half and five-eighth elements, an extensive adjustment is already achieved without the possible division during assembly.

The shape of the angled bubble 18 on the plates 11 is designed so that the rain tightness of the horizontal joint is secured and the gap 19 between the iTase 18 and the plate 11 in connection with the openings 20 in the connecting strips 14 fixed by the knobs 10 between the plates 11 and the thermal insulation element 3 further air space 21 influenced so that a discharge of the vapor pressure is ensured is, but the thermal insulation effect is retained.

Die Form der Nase 18, die Anordnung der Öffnungen 20 und der Klemmleisten 14 bewirkt darüberhinaus, daß evtl. The shape of the nose 18, the arrangement of the openings 20 and the clamping strips 14 also has the effect that possibly

sich bildendes Kondenswasser an der Platteninnenseite 11 nach außen abgeleitet wird.condensation water that forms on the inside of the plate 11 to the outside is derived.

Die gesamte Formgebung der Systemteile ist so abgestimmt, daß durch Mehrfachwirkungen wirtschaftlich Anforderungen aus bauphysikalischer und architektonischer Sicht sowie seitens der Montage weitgehend berücksichtigt werden, was bei der Anspruchsformulierung zum Ausdruck kommt. The entire design of the system parts is coordinated so that through Multiple effects economic requirements from building physics and architectural View as well as on the part of the assembly are largely taken into account, which is when formulating the claim is expressed.
