Description

Die Erfindung betrifft eine Isolierleiste für thermisch isolierte Rahmen insbesondere für Fassaden-, Tür- und Fensterelemente aus einem zweiteiligen Metallprofil, die zwischen dessen beide Teile zur thermischen Trennung eingefügt ist und mindestens einen Kunststoffsteg aufweist, an den ein Leistenfuß und einen Leistenkopf, die in entsprechende Aufnahmen an den Metallprofilteilen einsetzbar sind, angeformt sind.The invention relates to an insulating strip for thermally insulated Frame especially for facade, door and window elements from one two-part metal profile, which between the two parts for thermal separation is inserted and at least one plastic web has a groin foot and a groin head, which in appropriate receptacles can be used on the metal profile parts, are molded.

Bei der thermischen Isolierung von Fassaden, Türen, Fenstern werden Rahmen eingesetzt, die aus zweiteiligen Metallprofilen zusammengesetzt sind, wobei die Rahmen die Elemente der Fassaden-, Tür- und Fenster als entsprechende Füllungen aufnehmen. Als Metallprofile werden vorzugsweise stranggepresste Profile etwa auch Aluminium eingesetzt, die in die gewünschten Füllungselemente eingesetzt werden. Diese Metallprofile stellen unisoliert "Kältebrücken" dar, über die Wärme unerwünscht abfließt. Um ein solches unerwünschtes Abfließen von Wärme zu unterbinden, werden diese Metallprofile geteilt und zwischen die beiden Teile Kunststoffstege als Isoliereinsätze eingefügt, die diese beiden Teile mechanisch miteinander so verbinden, dass die für den Einsatzfall notwendige mechanische Stabilität des mit der Füllung versehenen Rahmens erreicht wird.In the thermal insulation of facades, doors, windows Frame used, which is composed of two-part metal profiles are, the frames being the elements of the facade, door and Include windows as appropriate fillings. As metal profiles are preferably extruded profiles such as aluminum used, which are inserted into the desired filling elements. These metal profiles represent "cold bridges" without insulation, over which heat flows away undesirably. To such an undesirable To prevent heat from flowing away, these metal profiles are divided and between the two parts plastic webs as insulating inserts inserted these two parts mechanically together connect in such a way that the mechanical Stability of the frame provided with the filling is achieved.

Diese Kunststoffstege unterbrechen den Wärmeabschluss und somit wird die Kältebrücke unterbrochen und der Abfluss von Wärme behindert, Diese Behinderung des Wärmeabflusses - gemessen mit dem Wärmedurchlasskoeffizienten, dem U-Wert (früher K-Wert) - wird dabei wesentlich von dem Wärmedurchlass dieser Kunststoffstege bestimmt. Nach dem Stand der Technik werden thermisch isolierte Profile so ausgebildet, dass der U-Wert möglichst unter 2,0 W/m2 K liegt. Damit lassen sich jedoch die gestiegenen Anforderungen an die Verringerung von Wärmeverlusten nicht mehr realisieren. Um die Wärmeverluste noch weiter herabzusetzen, müsste der Wärmedurchgang durch die Isolierstege noch weiter reduziert werden. Dazu bieten sich nach den Gesetzen der Physik zum einen eine Weg-Verlängerung der Wärmeleitstrecke an, wie zum anderen eine Verringerung ihres Querschnittes. Beide Maßnahmen führen jedoch dazu, dass die Kunststoffstege ihre für die Festigkeit der Rahmen notwendige mechanische Stabilität verlieren.These plastic webs interrupt the heat closure and thus the cold bridge is interrupted and the outflow of heat is hindered. This obstruction of the heat outflow - measured with the heat transfer coefficient, the U-value (formerly K-value) - is essentially determined by the heat transmission of these plastic webs. According to the prior art, thermally insulated profiles are formed in such a way that the U-value is below 2.0 W / m 2 K if possible. However, this means that the increased requirements for reducing heat losses can no longer be met. In order to reduce the heat losses even further, the heat transfer through the insulating webs would have to be reduced even further. According to the laws of physics, there is a way of extending the heat conduction path and reducing its cross-section. However, both measures lead to the fact that the plastic webs lose their mechanical stability necessary for the strength of the frame.

Hier setzt die Erfindung ein, der die Aufgabenstellung zugrunde liegt, die bekannten Kunststoffstege für Rahmen derart weiterzubilden, dass sowohl die den Wärmeabfluss bestimmende Weglänge verlängert, wie auch der den Wärmeabfluss bestimmende Querschnitt verringert werden kann, unter Erhalt der mechanischen Stabilität, wobei derartig weitergebildete Kunststoffstege wirtschaftlich und kostengünstig herstell- und einsetzbar sein sollen, und wobei mit ihnen U-Werte unter 2,0 W/m2 K angestrebt werden.This is where the invention comes in, which is based on the task of further developing the known plastic webs for frames in such a way that both the path length determining the heat flow and the cross section determining the heat flow can be reduced, while maintaining the mechanical stability, such further developed plastic webs should be economical and inexpensive to manufacture and use, and with them U-values below 2.0 W / m 2 K are aimed.

Die Lösung dieser Aufgabenstellung wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs definiert: vorteilhafte Weiterbildungen und bevorzugte Ausführungsformen beschreiben die abhängigen Ansprüche.The solution to this problem is the characteristic Features of the independent claim defined: advantageous developments and preferred embodiments describe the dependent ones Expectations.

Um bei verlängerten Isolierstegen mit verringerter Dicke die gewünschte mechanische Stabilität zu erreichen, wird der Isoliersteg mit einem im spitzen Winkel abstehenden Stützsteg versehen, der an den Kopf des Isoliersteges so angeformt ist, dass der Kopf in die Aufnahme an dem zugeordneten Metallprofilteil eingesetzt werden kann. Die Länge dieses so angeformten Stützsteges ist dabei darauf abgestellt, dass sein freies Ende auf einer Innenseite des zugeordneten Metallprofilteils aufliegt. Mit dieser einem "V" entsprechenden Ausbildung des Kunststoffsteges wird eine Versteifung erreicht, die sowohl bei verlängerten Kunststoffstegen wie auch bei Verringerung ihrer Dicke die für die Rahmenstabilität notwendige bzw. gewünschte mechanische Stabilität sicherstellen.In order to achieve the desired length with reduced insulating bars with reduced thickness To achieve mechanical stability, the insulating bridge provided with a support bar that protrudes at an acute angle the head of the insulating web is molded so that the head in the Recording used on the assigned metal profile part can. The length of this shaped support web is on it parked that its free end on an inside of the associated Metal profile part rests. With this corresponding to a "V" Formation of the plastic web stiffening is achieved both with extended plastic webs and with reduction its thickness is the necessary or desired for the frame stability ensure mechanical stability.

Dieses Sicherstellen wird unterstützt, wenn zwischen Isoliersteg und Stützsteg mindestens eine Querabstützung vorgesehen ist. Diese Querabstützung verbindet Kunststoffsteg und Stützsteg im Sinne eines Tragwerks. Diese Querabstützung wird dabei nahe dem fußseitigen Ende des Stützsteges vorgesehen, oder sie ist im Bereich der Mitte angeordnet, wobei hierunter die Lage im Bereich von etwa 35% bis zu etwa 65 % der Länge des Kunststoffsteges zu verstehen ist. Vorteilhaft ist es, wenn zwei Abstützungen vorgesehen sind, eine etwa mittig, die andere etwa im Fußbereich. Diese Ausbildung ergibt eine Querschnittsgeometrie die sich in eine Extrusionsform umsetzen lässt und somit ein wirtschaftliches Herstellen von extrudierten Kunststoffprofilen erlaubt, von denen dann derartige Kunststoffstege abgelängt werden können.This securing is supported if between the insulating bridge and support web at least one transverse support is provided. This Cross support connects plastic web and support web in the sense of one Structure. This cross support is close to the foot side End of the support web provided, or it is in the middle arranged, including the location in the range of about 35% up to about 65% of the length of the plastic web is to be understood. Advantageous if two supports are provided, one approximately in the middle, the other in the foot area. This training results in a Cross-sectional geometry that translate into an extrusion mold leaves and thus an economical manufacture of extruded Plastic profiles allowed, of which then such plastic webs can be cut to length.

Als Kunststoffe für solche extrudierten Kunststoffprofile werden thermoplastische Polymere vorgesehen, beispielsweise thermoplastische Polymerisate wie Polyvinylchlorid o.dgl. oder thermoplastische Polykondensate wie Polyamid o.dgl. Zur Erhöhung der Festigkeit können auch Faserverstärkungen vorgesehen werden, wobei es sich von selbst versteht, dass Kunststoff und Fasern aufeinander abgestimmt werden müssen.As plastics for such extruded plastic profiles thermoplastic polymers provided, for example thermoplastic Polymers such as polyvinyl chloride or the like. or thermoplastic Polycondensates such as polyamide or the like. To increase strength also fiber reinforcements are provided, it being from understands that plastic and fibers are coordinated Need to become.

Das thermisch isolierte Profil wird von einer Außenschale 1 und einer Innenschale 5 gebildet, die mittels einer zwischengefügten Isolierleiste 10 zusammengehalten werden. Die Außenschale 1 wird dabei von einem Außenflansch 2 und einem Innenflansch 3 gebildet, die durch Querstege 2.1 fest miteinander verbunden sind. Dabei ist die Außenschale 1 zur Außenseite oder zur Fassade hin gerichtet. In gleicher Weise ist die Innenschale 5 aufgebaut: Sie besteht aus einem Außenflansch 6, einem Innenflansch 7 sowie diese beiden Flansche verbindende Querstege 6.1. Diese Außenschale ist zur Innenseite hin gerichtet. Außenschale 1 und Innenschale 5 sind miteinander durch eingesetzte Isolierleiste 10 nach dem Stand der Technik mit dem Kunststoffsteg 11 verbunden. Derartige Isolierleisten 10 mit ihrem längsverlaufenden Kunststoffsteg 11 werden durch Extrusion eines thermoplastischen Kunststoffes hergestellt, wobei sowohl der Leistenfuß 12 wie auch der Leistenkopf 14 bei der Extrusion des Kunststoffsteges 11 in bekannter Weise an diesen angeformt werden. Um die notwendige Festigkeit zu erreichen, weisen die Isolierleisten 10 nach dem Stand der Technik eine (relativ) große Dicke und somit einen (verhältnismäßig) großen Querschnitt auf. Damit wird dem (unerwünschten) Wärmedurchgang Vorschub geleistet.The thermally insulated profile is made of an outer shell 1 and one Inner shell 5 formed by means of an interposed insulating strip 10 are held together. The outer shell 1 is formed by an outer flange 2 and an inner flange 3, the are firmly connected to each other by crossbars 2.1. Here is the Outer shell 1 directed towards the outside or towards the facade. In the inner shell 5 is constructed in the same way: it consists of a Outer flange 6, an inner flange 7 and these two flanges connecting crossbars 6.1. This outer shell is on the inside directed towards. Outer shell 1 and inner shell 5 are together by using insulating strip 10 according to the prior art connected to the plastic web 11. Such insulating strips 10 with their longitudinal plastic web 11 are made by extrusion made of a thermoplastic, both the Last foot 12 as well as the last head 14 in the extrusion of the Plastic web 11 can be molded onto them in a known manner. To achieve the necessary strength, the insulating strips have 10 according to the prior art a (relatively) large thickness and thus a (relatively) large cross-section. So that will the (undesirable) heat transfer.

Die einander zugewandten Seiten der Innenflansche 3 und 7 sind mit einander zugekehrten Aufnahmen 4 und 8 versehen, von denen die eine den Leistenfuß 12 und die andere den Leistenkopf 14 formschlüssig so aufnimmt, dass die beiden Schalen 1 und 5 im von Kunststoffsteg 11 gegebenen Abstand aneinander fixiert sind. Dabei sind diese Außen- und Innenschalen 1 und 5 stranggepresste Metallprofile, vorzugsweise Aluminiumprofile, die so ohne weiteres mit der längsverlaufenden Aufnahme 4 für den Leistenfuß 12 und der dazu korrespondierenden, ebenfalls längsverlaufenden Aufnahme 9 für den Leistenkopf 14 versehen sind.The mutually facing sides of the inner flanges 3 and 7 are with facing recordings 4 and 8, one of which the inguinal foot 12 and the other the form of the inguinal head 14 so that the two shells 1 and 5 in the plastic web 11 given distance are fixed to each other. These are external and inner shells 1 and 5 extruded metal profiles, preferably Aluminum profiles that easily match the longitudinal Recording 4 for the last foot 12 and the corresponding, also longitudinal recording 9 for the inguinal head 14 are provided.

Um diesen den Wärmedurchgang beeinflussenden Querschnitt zu verkleinern wird die Isolierleiste 15 nach der Erfindung als Tragwerk ausgebildet. Dazu ist an den Leistenkopf 18 eine im spitzen Winkel abstehender Stützschenkel 20 angeformt, dessen freies Ende auf der Innenseite des Innenflansches 7 der Innenschale 5 aufsteht, wenn der Leistenkopf 18 in die Aufnahme 4 auf der Innenseite des Innenflansches 3 der Außenschale 1 eingesetzt ist. Dabei steht das freie Ende 21 des Stützschenkels 20 auf der Innenseite des Innenflansches 7 der Innenschale 5 neben der Aufnahme für den Leistenfuß auf. Es versteht sich dabei von selbst, dass die Umkehrung, so dass das freie Ende 21 des Stützschenkels 20 auf der Innenseite des Innenflansches 3 der Außenschale 1 aufsteht, den gleichen Effekt bewirkt. Derartig ausgebildete Isolierleisten 15 lassen sich in gleicher Weise herstellen, wie die Isolierleisten 10 nach dem Stand der Technik: Diese Isolierleisten 15 mit ihrem längsverlaufenden Kunststoffsteg 16 werden durch Extrusion eines thermoplastischen Kunststoffes hergestellt, wobei sowohl der Leistenfuß 17 wie auch der Leistenkopf 18 sowie auch der Stützschenkel 20 und ggf. die Stabilisierungsstege 22 bei der Extrusion des Kunststoffsteges 16 in bekannter Weise an diesen angeformt werden.In order to reduce this cross-section influencing the heat transfer is the insulating strip 15 according to the invention as a structure educated. For this purpose, there is an acute angle to the ledge head 18 protruding support leg 20 formed, the free end on the Inside of the inner flange 7 of the inner shell 5 stands up when the inguinal head 18 in the receptacle 4 on the inside of the inner flange 3 of the outer shell 1 is inserted. The free one stands there End 21 of the support leg 20 on the inside of the inner flange 7 of the inner shell 5 next to the socket for the groin foot. It it goes without saying that the reversal, so that free end 21 of the support leg 20 on the inside of the inner flange 3 of the outer shell 1 stands up, has the same effect. Insulating strips 15 designed in this way can be made in the same Manufacture how the insulating strips 10 according to the state of the Technology: These insulating strips 15 with their longitudinal plastic web 16 are made by extrusion of a thermoplastic manufactured, both the last foot 17 and the Groin head 18 and also the support leg 20 and possibly the stabilizing webs 22 in the extrusion of the plastic web 16 in known Be molded on this way.

Durch diese Abstützung kann der gesamte dem Wärmeabfluss zur Verfügung stehende Querschnitt so verringert werden, dass mit einem solchen Profil ein Wärmedurchflusskoeffizient von unter 2.0 erreicht wird. Um diese Abstützung zu stabilisieren, ist es vorteilhaft, wenn zwischen dem Kunststoffsteg 16 und dem Stützschenkel 20 zumindest ein Stabilisierungssteg 22 angeordnet ist, der vorteilhaft auf dem Kunststoffsteg 16 rechtwinklig aufsteht. Vorteilhaft werden mehrere solcher Stabilisierungsstege 22 vorgesehen.This support allows the entire heat flow to be available standing cross section can be reduced so that with a such a profile has a heat flow coefficient of less than 2.0 becomes. In order to stabilize this support, it is advantageous if between the plastic web 16 and the support leg 20 at least one stabilizing web 22 is arranged, which is advantageous stands on the plastic web 16 at right angles. Advantageous several such stabilizing webs 22 are provided.

Da die Isolierleiste 15 wie die Isolierleiste 10 extrudierte Kunststoffprofile sind, lassen sich sowohl die Stützschenkel 20 wie auch die Stabilisierungsstege 22 in einfacher Weise im Zuge der Extrusion anformen, so dass auch die Isolierleiste 15 in einfacher Weise und kostengünstig herstellbar ist. Da der Stützschenkel 20 frei auf der Innenseite des Innenflansches 7 der Innenschale 5 aufsteht, bedarf es keiner weiteren Aufnahmen, so dass auch die Montage solcher Isolierleisten 15 einfach und kostengünstig bewerkstelligt werden kann.Since the insulating strip 15 as the insulating strip 10 extruded plastic profiles are, both the support legs 20 and the stabilizing webs 22 in a simple manner in the course of the extrusion form, so that the insulating strip 15 in a simple manner and is inexpensive to manufacture. Since the support leg 20 is free the inside of the inner flange 7 of the inner shell 5 stands up there are no further recordings, so that the assembly of such Insulating strips 15 can be accomplished easily and inexpensively can.
