Description
Die vorliegende Erfindung betrifft eine Fassade oder ein Lichtdach mit den Merkmalen des Oberbegriffes des Anspruches 1, sowie ein Verfahren zum Herstellen eines Isoliersteges.The present invention relates to a facade or a light roof with the features of the preamble of claim 1, and a method for producing an insulating web.
Die
Es ist daher Aufgabe der vorliegenden Erfindung eine Fassade oder ein Lichtdach zu schaffen, bei dem ein einfach herzustellender Isoliersteg mit hoher Wärmedämmung vorgesehen ist.It is therefore an object of the present invention to provide a facade or a light roof, in which a simple-to-manufacture insulating bar is provided with high thermal insulation.
Diese Aufgabe wird mit einer Fassade oder Lichtdach mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a facade or light roof with the features of claim 1.
Erfindungsgemäß umfasst der Isoliersteg zwei unterschiedliche Materialien und weist einen Teil mit einem härteren und weicheren Material auf. Das Teil aus einem härteren Material bildet dabei mindestens eine Aufnahme aus, in die ein Teil aus weicherem Material mit hoher Wärmedämmung zumindest bereichsweise eingefügt ist. Dadurch kann das weichere Material mit hoher Konturgenauigkeit in die Aufnahme eingefügt werden und kann dementsprechend mit geringeren Toleranzen hergestellt werden. Das Teil aus härterem Material kann über einen Befestigungsabschnitt zudem die Fixierung des Isoliersteges an einer Schraubnut sicher gewährleisten, sodass der Isoliersteg eine hohe Wärmedämmung und einfache Montage ermöglicht.According to the invention, the insulating web comprises two different materials and has a part with a harder and softer material. The part of a harder material forms at least one recording, in which a part made of softer material with high thermal insulation is at least partially inserted. As a result, the softer material with high contour accuracy can be inserted into the receptacle and can therefore be manufactured with lower tolerances. The part made of harder material can also ensure the fixation of the insulating bar on a screw securely on a mounting portion, so that the insulating bar allows high thermal insulation and ease of installation.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist das Teil aus weicherem Material in einer Aufnahme in Form eines offenen oder geschlossenen Hohlraumes in dem Teil aus härterem Material angeordnet. Die Aufnahme an dem härteren Teil kann dabei wannenförmig oder schalenförmig sein und im Querschnitt beispielsweise U-, C- oder O-förmig ausgebildet sein, sodass die Aufnahme das weichere Material zumindest teilweise umgibt, vorzugsweise um mindestens mehr als 180°. Dadurch wird eine stabile Befestigung des weicheren Materials innerhalb der Aufnahme gewährleistet. In der Aufnahme können zudem ein oder mehrere Halteelemente vorgesehen sein, die in die Aufnahme ragen und zur Fixierung des weicheren Materials vorgesehen sind. Als Halteelemente können Stege dienen, die sich dann in das weiche Material verkrallen.According to a preferred embodiment of the invention, the part of softer material is arranged in a receptacle in the form of an open or closed cavity in the part of harder material. The receptacle on the harder part can be trough-shaped or cup-shaped and, for example, U-shaped, C-shaped or O-shaped in cross-section so that the receptacle at least partially surrounds the softer material, preferably by at least more than 180 °. This ensures a stable attachment of the softer material within the receptacle. In addition, one or more retaining elements may be provided in the receptacle, which project into the receptacle and are provided for fixing the softer material. As holding elements webs can serve, which then dig into the soft material.
Vorzugsweise ist das Teil aus weicherem Material in die Aufnahme des Teils aus härterem Material eingeschäumt. Das Einschäumen kann dabei schon während oder nach der Herstellung des Isoliersteges erfolgen, sodass das weichere Material dauerhaft mit dem Teil aus härterem Material verbunden ist. Das Teil aus weicherem Material kann als Profil ausgebildet sein und eine entsprechende Kontur aufweisen, welche in das Teil aus härterem Material eingefügt werden kann.Preferably, the part of softer material is foamed into the receptacle of the part of harder material. The foaming can already take place during or after the production of the insulating web, so that the softer material is permanently connected to the part made of harder material. The part of softer material may be formed as a profile and have a corresponding contour which can be inserted into the part of harder material.
Für eine hohe Wärmedämmung erstreckt sich das Teil aus weicherem Material über mindestens 60%, insbesondere mindestens 80 %, der Länge der Stirnseiten der Füllungselemente. Dadurch wird die Wärmedämmung verbessert, da bei vorbekannten Lösungen ein Teil aus weicherem Material sich nur über eine geringe Länge bezogen auf die Länge der Stirnseiten von innen nach außen erstrecken.For a high thermal insulation, the part of softer material extends over at least 60%, in particular at least 80%, of the length of the end faces of the filling elements. As a result, the thermal insulation is improved because in prior art solutions a part of softer material only over one short length based on the length of the end faces extend from the inside out.
Um die Wärmedämmung weiter zu verbessern, weist der Isoliersteg an gegenüberliegenden Seiten jeweils mindestens eine Dichtlippe auf, die sich zu einer Stirnseite der Füllungselemente erstreckt. Vorzugsweise sind mehrere Dichtlippen auf jeder Seite angeordnet, die den Zwischenraum zwischen Isoliersteg und den Stirnseiten in einzelne Kammern unterteilen, die ein unterschiedliches Temperaturniveau besitzen können. Die Dichtlippen bestehen vorzugweise aus dem Teil aus härterem Material, sodass eine positionsgenaue Anordnung der Dichtlippen ermöglicht wird. Es ist auch möglich, dass die Dichtlippen mit Übermaß aus weicherem Material herzustellen, um eine Anlage an der Stirnseite vorzusehen.In order to further improve the thermal insulation, the insulating web has on opposite sides in each case at least one sealing lip, which extends to an end face of the filling elements. Preferably, a plurality of sealing lips are arranged on each side, which divide the space between the insulating web and the end faces into individual chambers, which may have a different temperature level. The sealing lips are preferably made of the part of harder material, so that a positionally accurate arrangement of the sealing lips is made possible. It is also possible that the sealing lips with excess of softer material to produce, to provide an investment on the front page.
Der Wärmedurchgangskoeffizient des weicheren Materials liegt vorzugsweise in einem Bereich zwischen 0,01 bis 0,04 W/mK, insbesondere zwischen 0,02 bis 0,03 W/mK, sodass eine hohe Wärmedämmung erreicht werden kann. Der Wärmedurchgangskoeffizient für das härtere Material des Isoliersteges liegt in einem Bereich von beispielsweise 0,15 W/mK bis 0,3 W/mK. Das härtere Material kann zumindest bereichsweise mit einer reflektierenden Beschichtung überzogen sein, um die Wärmedämmung zu verbessern.The heat transfer coefficient of the softer material is preferably in a range between 0.01 to 0.04 W / mK, in particular between 0.02 to 0.03 W / mK, so that a high thermal insulation can be achieved. The heat transfer coefficient for the harder material of the insulating strip is in a range of, for example, 0.15 W / mK to 0.3 W / mK. The harder material may at least partially be coated with a reflective coating to improve the thermal insulation.
Der Isoliersteg weist vorzugsweise an einer Innenseite einen Befestigungsabschnitt und an einer Außenseite einen Halteabschnitt aus dem härteren Material auf, die beabstandet angeordnet sind und nur über einen Steg aus weicherem Material miteinander verbunden sind. Dadurch wird vermieden, dass sich ein Steg von einer Außenseite des Isoliersteges zu einer Innenseite erstreckt, da der Halteabschnitt an der Außenseite beabstandet von dem Befestigungsabschnitt an der Innenseite angeordnet ist. Dadurch wird die Wärmedämmung besonders hoch und es ist möglich, dass der Befestigungsabschnitt und Halteabschnitt mechanische Funktionen übernehmen, beispielsweise die Vorfixierung der Füllungselemente. Der Abstand zwischen dem Befestigungsabschnitt und dem Halteabschnitt kann in einem Bereich zwischen 0,5 cm bis 3 cm liegen, sodass in diesem Bereich keine Kältebrücke durch einen Materialabschnitt aus härterem Material gebildet ist. An dem Halteabschnitt kann dabei zumindest an einer Seite ein äußerer Steg an eine Außenseite eines Füllungselementes aufliegen, vorzugsweise ist an den gegenüberliegenden Seiten jeweils ein Halteabschnitt vorgesehen, mittels dem die Füllungselemente vorfixiert werden können.The insulating web preferably has on an inner side a mounting portion and on an outer side a holding portion of the harder material, which are arranged at a distance and are connected to each other only via a web of softer material. This prevents a web from extending from an outer side of the insulating strip to an inner side, since the holding section is arranged on the outer side at a distance from the fastening section on the inner side. As a result, the thermal insulation is particularly high and it is possible that the attachment portion and holding portion take over mechanical functions, such as the prefixing of the filling elements. The distance between the attachment portion and the holding portion may be in a range between 0.5 cm to 3 cm, so that in this area no cold bridge is formed by a material portion of harder material. An outer web can rest on an outer side of a filling element on at least one side of the holding section, preferably a holding section is provided on each of the opposite sides, by means of which the filling elements can be prefixed.
Gemäß einer weiteren Ausgestaltung der Erfindung weist der Befestigungsabschnitt zwei Schenkel auf, die klemmend an der Schraubnut fixiert sind. Die beiden Schenkel können die Schraubnut dabei U-förmig umgreifen, sodass auch die Schraubnut durch die Schenkel überdeckt wird und somit geschützt angeordnet ist.According to a further embodiment of the invention, the attachment portion has two legs, which are fixed in a clamping manner on the screw groove. The two legs can surround the screw groove while U-shaped, so that the Schraubnut is covered by the legs and thus is arranged protected.
An der Außenseite des Isoliersteges kann der Halteabschnitt vorzugsweise eine V-Einbuchtung aufweisen. Dadurch kann die Einbuchtung als Zentrierhilfe zum Eindringen von Befestigungsschrauben dienen, die der Schraubnut zur Fixierung der Halteleiste eingedreht werden. Durch eine zusätzliche Materialverstärkung im Bereich der Einbuchtung oder statt der Einbuchtung kann die Halteleiste auch mit einer Schraube an der Außenseite des Isoliersteges befestigt werden. Hierdurch wird eine Wärmebrücke von der Halteleiste zur Schraubnut durch eine durchgehende Schraube vermieden.On the outside of the insulating web, the holding portion may preferably have a V-indentation. As a result, the indentation can serve as a centering aid for the penetration of fastening screws, which are screwed into the screw groove for fixing the retaining strip. By an additional material reinforcement in the region of the indentation or instead of the indentation, the retaining strip can also be fastened with a screw on the outside of the insulating strip. As a result, a thermal bridge is avoided by the retaining strip for Schraubnut by a continuous screw.
Bei einem erfindungsgemäßen Verfahren zum Herstellen eines Isoliersteges wird in eine im Wesentlichen schlauchförmige Aufnahme an einem Teil aus härterem Material ein Teil aus weicherem Material mit hoher Wärmedämmung eingebracht, vorzugsweise eingeschäumt. Dabei kann nach dem Einbringen des Materials mit hoher Wärmedämmung das Teil aus härterem Material in einem Bereich der schlauchförmigen Aufnahme zumindest teilweise wieder entfernt werden, beispielsweise kann ein schmaler Streifen des härteren Materials entfernt werden, damit ein äußerer Halteabschnitt und ein innerer Befestigungsabschnitt beabstandet von einander angeordnet sind. Das Abtrennen eines solchen Streifens kann durch Perforation erleichtert werden, die in dem Teil aus härterem Material eingebracht sind, damit dann nach dem Einbringen des Materials mit hoher Wärmedämmung ein Abziehen des Streifens erfolgen kann.In a method according to the invention for producing an insulating web, a part made of a softer material with high thermal insulation is introduced, preferably foamed, into a substantially tubular receptacle on a part made of harder material. In this case, after the introduction of the material with high thermal insulation, the part made of harder material in a region of the tubular receptacle can be at least partially removed, for example, a narrow strip of the harder material can be removed so that an outer holding portion and an inner mounting portion spaced from each other are. The separation of such a strip can be facilitated by perforation, which are introduced in the part of harder material, so that then after the introduction of the material with high thermal insulation, a stripping of the strip can take place.
