Aus der DE 198 18 769 Al ist ein Isoliersteg bekannt, der aus Kunststoff und einer eingebetteten Metalleinlage besteht. Die Metalleinlage und der Kunststoff weisen Aussparungen auf, die zu einer leiterartigen Struktur des Leitersteges führen. Die Metalleinlage dient zur Verhinderung eines Totalversagens des Isolierstegs im Brandfall. Die Aussparungen in der Metalleinlage haben den Zweck, die Wärmeleitung zu reduzieren.From DE 198 18 769 Al a Isoliersteg is known, which consists of plastic and an embedded metal insert. The metal insert and the plastic have recesses, which lead to a ladder-like structure of the conductor bar. The metal insert serves to prevent a total failure of the insulating strip in case of fire. The recesses in the metal insert have the purpose of reducing the heat conduction.

Die Sprossen bzw. genauer die Ausnehmungen werden danach durch eine Bearbeitung wie eine spanende Bearbeitung (z.B. Fräsen), Schneiden (wie z.B. Laserschneiden, Wasserstrahlschneiden, etc.), Stanzen, usw. hergestellt. Das ausgenommene Material kann recycelt werden.It will specify a composite profile, in particular a metal composite profile, in which the outer profile parts (eg outer shell and inner shell) made of metal, for example, are connected by means of one or more of the insulating webs made of plastic. A relative movement in the longitudinal direction is limited or prevented by the high shear stiffness (character of the rungs in width, thickness, length, number). Advantageously, the insulating bars are first made of a suitable material, for example by extrusion as profile parts with a constant cross-section over the length. The sprouts or more precisely the recesses are then produced by a machining such as a machining (eg milling), cutting (such as laser cutting, water jet cutting, etc.), punching, etc. The reclaimed material can be recycled.
Die Metallprofϊlteile werden fest und damit unverlierbar mit dem Isoliersteg verbunden.The metal profile parts are firmly and thus captively connected to the insulating bar.
Zur Abdeckung der Zwischenräume zwischen den Sprossen können die Isolierstege mit Abdeckprofilen oder Abdeckfolien versehen werden. Die Abdeckprofile oder Abdeckfolien können z.B. angeclipst, angeklebt, anextrudiert, auflaminiert, etc. werden. Es ist auch alternativ oder zusätzlich möglich, die Zwischenräume zwischen den Leitersprossen mit einem Material, das einen niedrigeren Wärmeleitungskoeffizienten als das Material der Sprossen aufweist, auszufüllen. Die Funktion solcher Abdeckprofile etc. ist einerseits der Schutz vor dem Eindringen von Feuchtigkeit, andererseits der Schutz des Innenkerns. Die Abdeckprofile oder Abdeckfolien können vor oder nach der Montage der Türen angebracht werden. Mit den Abdeckprofilen oder Abdeckfolien kann der Feuchtigkeitsschutz sichergestellt werden. Zusätzlich können dekorative Elemente angebracht werden. Z.B. kann das Abdeckelement elektrisch leitfähig ausgeführt werden und damit bei der Pulverlackierung die Farbe der Metallprofile annehmen. Ebenfalls ist eine Bedruckung möglich.To cover the spaces between the rungs, the insulating bars can be provided with cover profiles or cover sheets. The cover profiles or cover sheets may e.g. clipped, glued, extruded, laminated, etc. It is also alternatively or additionally possible to fill the spaces between the ladder rungs with a material having a lower coefficient of thermal conductivity than the material of the rungs. The function of such cover profiles, etc., on the one hand the protection against the ingress of moisture, on the other hand, the protection of the inner core. The cover profiles or cover sheets can be applied before or after the installation of the doors. With the cover profiles or cover films, the moisture protection can be ensured. In addition, decorative elements can be attached. For example, the cover can be made electrically conductive and thus accept the color of the metal profiles in the powder coating. Also a printing is possible.
Ein Vorteil ist, dass die U- Werte (Wärmeleitungseigenschaften) der Isolierstege durch das Anbringen der Abdeckfolien/ Abdeckprofile/Füllungen, insbesondere der Abdeckprofile, nicht übermäßig verschlechtert werden.One advantage is that the U-values (thermal conduction properties) of the insulating bars are not excessively worsened by the attachment of the cover sheets / cover profiles / fillings, in particular the cover profiles.

Bei den in den Fig. 1, 2 gezeigten Isolierstegen verlaufen die Sprossen 23 des leiterartig ausgebildeten Isolierstegkörpers 20 zwischen den durchgehenden Längskanten 21 , 22 quer zur Längsrichtung Z. Diese können aber auch leicht geneigt ( bis ca. 20°) zur Querrichtung verlaufen. Die Sprossen können auch eine gekrümmte Form aufweisen. Vorzugsweise aber nicht notwendigerweise weisen alle Sprossen dieselbe Form auf.In the insulating webs shown in FIGS. 1, 2, the rungs 23 of the ladder-shaped Isolierstegkörpers 20 extend between the continuous longitudinal edges 21, 22 transversely to the longitudinal direction Z. But these can also be slightly inclined (up to about 20 °) to the transverse direction. The sprouts can also have a curved shape. Preferably, but not necessarily, all sprouts have the same shape.
Die Längsränder oder -kanten 21, 22 sind zur (in Längsrichtung z) schubfesten Verbindung mit Profilteilen 31, 32 (siehe Fig. 3) des Verbundprofils angepasst. In der gezeigten Ausführungsform sind die Längsränder oder -kanten 21, 22 als Einrollköpfe 25 oder Einrollvorsprünge ausgebildet für ein Einrollen in Nuten der Profilteile 31, 32, die jeweils von einem Einrollhammer 33 und gegenüberliegendem Wandabschnitt 34 gebildet werden. Andere Verbindungsarten wie Kleben etc. sind auch möglich.The longitudinal edges or edges 21, 22 are adapted to (in the longitudinal direction z) shear-resistant connection with profile parts 31, 32 (see FIG. 3) of the composite profile. In the embodiment shown, the longitudinal edges or edges 21, 22 are formed as curling heads 25 or curl projections for curling in grooves of the profile parts 31, 32, which are each formed by a rolling hammer 33 and opposite wall portion 34. Other types of connections such as gluing, etc. are also possible.
In einer Draufsicht weisen die Sprossen 23 eine Breite b in Längsrichtung z, die abhängig von der geforderten Querzugfestigkeit und der geforderten Quersteifigkeit und dem verwendeten Material gewählt wird und im Bereich von 0,5 bis 10mm, vorzugsweise, lmm bis 5mm, noch bevorzugter lmm bis 3mm liegt, auf. In einem Querschnitt senkrecht zur Längsrichtung weisen die Sprossen eine Höhe (Dicke) h (in Richtung y) auf, die abhängig von der geforderten Querzugfestigkeit und der geforderten Quersteifigkeit und dem verwendeten Material gewählt wird und im Bereich von 0,5mm bis 10mm, vorzugsweise, 0,5mm bis 5mm, noch bevorzugter 0,7mm bis 2mm liegt. Die Sprossen 23 sind in Längsrichtung z mit regelmäßigen Abständen d zwischen sich angeordnet, welche Abstände im Bereich von lmm bis 100mm, vorzugsweise lmm bis 50mm, noch bevorzugter lmm bis 5mm, und noch bevorzugter 1 bis 3 mm liegen. Natürlich sind auch andere Breiten, Dicken, Längen, und Abstände abhängig von den Anforderungen möglich.In a plan view, the rungs 23 have a width b in the longitudinal direction z, which is selected depending on the required transverse tensile strength and the required transverse rigidity and the material used and in the range of 0.5 to 10mm, preferably, lmm to 5mm, more preferably lmm to 3mm is up. In a cross-section perpendicular to the longitudinal direction, the rungs have a height (thickness) h (in the direction y) which is selected depending on the required transverse tensile strength and the required transverse rigidity and the material used and in the range of 0.5 mm to 10 mm, preferably 0.5mm to 5mm, more preferably 0.7mm to 2mm. The rungs 23 are arranged in the longitudinal direction z at regular intervals d between them, which distances are in the range of lmm to 100mm, preferably lmm to 50mm, more preferably lmm to 5mm, and more preferably 1 to 3mm. Of course, other widths, thicknesses, lengths, and distances are possible depending on the requirements.
Erste Prüfergebnisse wurden von leiterartigen Isolierstegen mit Sprossen erhalten, die in der Draufsicht in Längsrichtung des Isolierstegs bei einer ersten Ausführung eine Breite b von lmm und bei einer zweiten Ausführung von 3 mm aufwiesen und in der Längsrichtung des Isolierstegs jeweils regelmäßige Abstände d von ca. 3mm aufwiesen. Die Sprossen hatten in der Draufsicht in der Richtung quer zur Längsrichtung des Isolierstegs eine Länge c von ca. 14mm lang bei einer Gesamtabmessung a des Isolierstegs in dieser Richtung von ca. 23mm. Die Isolierstege zeigten Werte für die Querzugfestigkeit (Zug in der Richtung des Verbindens der mittels des Isolierstegs verbundenen Profilteile, also in Fig. 1 , 2 in Richtung x), die für beide Sprossenbreiten höher als für vergleichbare Profile nach DE 199 56 415 C1 waren, und für die Schubfestigkeit (gegenüber Verschieben der mittels des Isolierstegs verbundenen Profilteile in Längsrichtung z der Profilteile, also in Fig. 1 , 2 in der Längsrichtung Z), die einfach durch Wahl der Sprossenbreite auf Werte unter oder über den Werten für vergleichbare Profile nach DE 199 56415 Cl eingestellt werden konnten, so dass das Maß der Längsverschieb- barkeit bei sehr hoher Querzugfestigkeit einfach konfektionierbar ist. Diese Stege waren darauf ausgelegt, eine Längsverschieblichkeit zu gewährleisten, damit das sogenannte Bimetallproblem gemindert wird.First test results were obtained from ladder-type insulating bars with rungs, which in the plan view in the longitudinal direction of the insulating web in a first embodiment, a width b of lmm and in a second embodiment of 3 mm and in the longitudinal direction of the insulating each regular intervals d of about 3mm exhibited. The rungs had in plan view in the direction transverse to the longitudinal direction of the Isolierstegs a length c of about 14mm long with a total dimension a of the insulating bar in this direction of about 23mm. The Isolierstege showed values for the transverse tensile strength (train in the direction of connecting the connected by means of the insulating web profile parts, ie in Fig. 1, 2 in the direction x), which were higher for both rung widths than for comparable profiles according to DE 199 56 415 C1, and for the shear strength (relative to displacement of the profile webs connected by means of the insulating web in the longitudinal direction z of the profile parts, ie in Fig. 1, 2 in the longitudinal direction Z), simply by selecting the rung width to values below or above the values for comparable profiles according to DE 199 56415 Cl, so that the degree of longitudinal displacement can be easily assembled with very high transverse tensile strength. These webs were designed to ensure a longitudinal displacement, so that the so-called bimetallic problem is reduced.
Fig. 4 zeigt eine dritte Ausführungsform eines Isolierstegs mit mäanderförmigen Sprossen der leiterartigen Struktur in einer Fig. 1 a) entsprechenden Ansicht.Fig. 4 shows a third embodiment of an insulating web with meandering rungs of the ladder-like structure in a Fig. 1 a) corresponding view.
Bei der in Fig. 5 gezeigten vierten Ausführungsform eines Isolierstegs ist zur Abdeckung der Zwischenräume zwischen den Sprossen ein anextrudierter Deckel (Abdeckprofil) 40 vorgesehen, in einer Fig. 1 c) entsprechenden Ansicht. Das Abdeckprofil ist einstückig mit dem Steg ausgebildet. Das Abdeckprofil ist in einem Querschnitt senkrecht zur Längsrichtung z gesehen als ein Deckel an einer Seite der Sprossen (in x-Richtung gesehen) anextrudiert und sein freies Ende (Rand) ist auf der anderen Seite der Sprossen (in x-Richtung gesehen) angeclipst. Die Clipsverbindung ist so ausgebildet, dass das Einclipsen in Höhenrichtung (y-Richtung) erfolgt. In einer alternativen Ausfuhrungsform, die in Fig. 6 gezeigt ist, ist die Clipsverbindung anderes gestaltet, so dass schräg zur Höhenrichtung (y-Richtung) eingeclipst wird und eine Zugkraft in Querrichtung (x-Richtung) hält den Clip im Eingriff.In the fourth embodiment of an insulating web shown in FIG. 5, an anextruded cover (cover profile) 40 is provided to cover the spaces between the rungs, in a view corresponding to FIG. 1 c). The cover is formed integrally with the web. The cover profile is viewed in a cross section perpendicular to the longitudinal direction z as a lid on one side of the rungs (seen in the x direction) and its free end (edge) is clipped on the other side of the rungs (seen in the x direction). The clip connection is designed so that the clipping takes place in the vertical direction (y-direction). In an alternative embodiment shown in FIG. 6, the clip connection is configured differently so that it is clipped obliquely to the height direction (y direction) and a traction force in the transverse direction (x direction) engages the clip.
Bei der in Fig. 7 gezeigten fünften Ausführungsform ist der Isolierstegkörper 20 auf den Sprossen 23 mit Clipsköpfen (männlichen Clipsteilen) 28 versehen. Diese sind so angeordnet, dass in Höhenrichtung y auf einer Seite ein Clipskopf 28 und auf der anderen Seite zwei Clipsköpfe 28 angeordnet sind. Dabei ist der einzelne Clipskopf 28 in Querrichtung x mittig auf der Sprosse angeordnet, während die beiden anderen Clipsköpfe auf der anderen Seite mit identischem Abstand von der Mitte angeordnet sind.In the fifth embodiment shown in Fig. 7, the Isolierstegkörper 20 on the rungs 23 with clip heads (male clip parts) 28 is provided. These are arranged so that in the vertical direction y on one side of a clip head 28 and on the other side two clip heads 28 are arranged. In this case, the single clip head 28 is arranged in the transverse direction x centered on the rung, while the other two clip heads are arranged on the other side with an identical distance from the center.
Die Clipsköpfe stehen jeweils um eine Höhe h3 gegenüber der übrigen Oberfläche der Sprossen 23 des Isolierstegkörpers 20 vor. Die Summe aus der Dicke hi in Höhenrichtung y und zweimal dem Überstand h3 ist bevorzugt identisch zu der Dicke der Einrollköpfe 25 in Höhenrichtung y.The clip heads are in each case by a height h 3 with respect to the remaining surface of the rungs 23 of the Isolierstegkörpers 20 before. The sum of the thickness hi in the height direction Y and two times the projection h 3 is preferably identical to the thickness of Einrollköpfe 25 in height direction y.
Bei der fünften Ausführungsform ist ein Deckel (Abdeckprofil) 40 so ausgebildet, dass er an einer Seite drei Clipsaufnahmen (weibliche Clipsteile) 48 aufweist, von denen die beiden äußeren denselben Abstand wie die zwei auf einer Seite des Isolierstegkörpers 20 befindlichen Clipsköpfe 28 aufweisen und die dritte Clipsaufnahme mittig zwischen diesen angeordnet ist. Wie sich aus der Fig. 7 ohne weiteres ergibt, können derart Deckel auf beiden Seiten des Isolierstegkörpers 20 angeclipst werden, ohne dass unterschiedlich ausgebildete Deckel notwendig sind. Der Isolierstegkörper 20 weist über eine Breite ai in Querrichtung x eine im wesentlichen konstante Dicke hi auf. Die Breite a2 des Deckels 40 in Querrichtung x ist kleiner oder gleich dieser Breite ai des Isolierstegkörpers 20.In the fifth embodiment, a cover (cover profile) 40 is formed so that it has on one side three clip receptacles (female clip parts) 48, of which the two outer have the same distance as the two located on one side of Isolierstegkörpers 20 clip heads 28 and the third clip recording is arranged centrally between them. As can readily be seen from FIG. 7, such covers can be clipped on both sides of the insulating body 20 without the need for differently designed lids. The Isolierstegkörper 20 has over a width ai in the transverse direction x to a substantially constant thickness hi. The width a 2 of the cover 40 in the transverse direction x is less than or equal to this width ai of the Isolierstegkörpers 20th
Der Deckel weist an seinen in Längsrichtung Z verlaufenden Rändern in der Querrichtung x ausgebildete Anlagelippen 42 auf. Die Clipsaufnahmen (weiblichen Clipsteile) 48 weisen einen Abstand I14 von dem Boden der Clipsaufnahme in Höhenrichtung y zu dem äußersten Punkt der Clipsaufnahme auf, der kleiner als die Höhe h3 der Clipsköpfe 28 ist. Die Lippen 42 enden in Höhenrichtung y auf dem Höhenniveau der Clipsaufnahmen 48 oder etwas höher (siehe auch Fig. 7 c)). Als Material für den Isoliersteg wird vorteilhafterweise Kunststoff mit einem E-Modulwert größer 2000 N/mm2 verwendet. Geeignete Kunststoffe sind Polyamid, Polyester oder Polypropylen, zum Beispiel PA66.The cover has contact lips 42 formed on its edges running in the longitudinal direction Z in the transverse direction x. The clip receptacles (female clip parts) 48 have a distance I1 4 from the bottom of the clip receptacle in the height direction y to the outermost point of the clip receptacle, which is smaller than the height h 3 of the clip heads 28. The lips 42 end in the height direction y at the height level of the clip receptacles 48 or slightly higher (see also Fig. 7 c)). As a material for the insulating web advantageously plastic with an E-modulus greater than 2000 N / mm 2 is used. Suitable plastics are polyamide, polyester or polypropylene, for example PA66.
Die Dicke 1I1 der Isolierstegkörper aller Ausführungsformen liegt im Bereich von 1 mm bis 50 mm, vorzugsweise 1 mm bis 10 mm, noch bevorzugter 1 mm bis 2 mm, noch bevorzugter 1,4 bis 1,8 mm. Die Dicke h2 der Deckel ist bevorzugt kleiner oder gleich der Dicke des zugehörigen Isolierstegkörpers.The thickness 1I 1 of the insulating bridge bodies of all embodiments is in the range of 1 mm to 50 mm, preferably 1 mm to 10 mm, more preferably 1 mm to 2 mm, more preferably 1.4 to 1.8 mm. The thickness h 2 of the cover is preferably less than or equal to the thickness of the associated Isolierstegkörpers.
Die in den Fig. 5 und 6 gezeigte Ausführungsform ist für kleinere Werte von a im Bereich von 8 bis 20 mm, beispielsweise 14 mm gut geeignet. Die Dicke hi beträgt dann bevorzugt zum Beispiel 1 ,4 mm. Die Ausführungsform gemäß Fig. 7 ist für Werte von a im Bereich von 20 bis 40 mm, z.B. 32 mm, gut geeignet. In diesem Fall liegt die bevorzugte Dicke hi im Bereich von 1,5 bis 1,8 mm. Für die angegebenen Breiten und Materialstärken wird als Material PA66 bevorzugt.The embodiment shown in Figures 5 and 6 is well suited for smaller values of a in the range of 8 to 20 mm, for example 14 mm. The thickness hi is then preferably, for example, 1.4 mm. The embodiment of Fig. 7 is for values of a in the range of 20 to 40 mm, e.g. 32 mm, well suited. In this case, the preferred thickness hi is in the range of 1.5 to 1.8 mm. For the indicated widths and material thicknesses PA66 is preferred as the material.
Da die Isolierstegkörper aus Kunststoff bestehen, weisen keine Metalleinlage auf, d.h. sie sind ohne Metalleinlage ausgebildet.Since the Isolierstegkörper consist of plastic, have no metal insert, i. they are formed without metal insert.
In Fig. 8 a) ist in einer Draufsicht senkrecht zur Längsrichtung eine im Hinblick auf Schubfestigkeit definierte Ausführungsform dargestellt. Der Isoliersteg weist eine Breite a in x- Richtung im Bereich 10mm < a < 100mm auf. Der Isoliersteg weist in Höhenrichtung (Dickenrichtung) y durch das Material des Stegs hindurchgehende Ausnehmungen 24 auf. Die Form der Ausnehmungen ist in der Draufsicht im Wesentlichen dreieckförmig, mit Ecken mit einer Innenrundung mit einem Radius R. Die Höhe der Dreiecke in Querrichtung x ist c. Die Dreiecke sind alternierend angeordnet. Dies bedeutet, in der Draufsicht in Fig. 8 a) ist jeweils eine Längsseite eines Dreiecks abwechselnd parallel nahe an der linken Seite, dann an der rechten Seite, dann wieder an der linken Seite, usw. angeordnet. Daraus folgt, dass auch die Spitzen alternierend angeordnet sind. Zwischen den Dreiecken befinden sich Sprossen 23, die eine Breite b senkrecht zu den sie begrenzenden Seiten der Dreiecke aufweisen. Die Dreiecke sind um ein Maß e von den jeweiligen Außenkanten in Querrichtung x entfernt. Daraus ergibt sich, dass a = c + 2e. Der Isoliersteg weist in Höhenrichtung y eine Höhe (Dicke) h über seine gesamte Breite, ausgenommen die Einrollköpfe 25 auf. Die Werte sind dabei wie folgt ge- wählt. Für Isolierstege mit a < 22mm liegt c im Bereich von 7 bis 10, bevorzugt 8mm. Der Radius R ist < 2mm, bevorzugt < lmm, noch bevorzugter 0,5mm. Der Radius dient dazu, eine Kerbwirkung und auch die Bildung einer Art von Biegegelenk zu vermeiden. Die Breite b der Sprossen beträgt 1 bis 3 mm, bevorzugt 2mm.In Fig. 8 a) a defined in terms of shear strength embodiment is shown in a plan view perpendicular to the longitudinal direction. The insulating web has a width a in the x direction in the range 10 mm <a <100 mm. The insulating web has in the height direction (thickness direction) y through the material of the web passing through recesses 24. The shape of the recesses is substantially triangular in plan view, with corners having an inner radius of radius R. The height of the triangles in the transverse direction x is c. The triangles are arranged alternately. That is, in the plan view in Fig. 8 (a), one longitudinal side of a triangle is alternately arranged in parallel near the left side, then on the right side, then again on the left side, and so forth. It follows that the tips are arranged alternately. Between the triangles are rungs 23 which have a width b perpendicular to the sides of the triangles delimiting them. The triangles are removed by a distance e from the respective outer edges in the transverse direction x. It follows that a = c + 2e. The insulating web has in height direction y a height (thickness) h over its entire width, except for the curling heads 25 on. The values are as follows: chooses. For Isolierstege with a <22mm c is in the range of 7 to 10, preferably 8mm. The radius R is <2mm, preferably <1mm, more preferably 0.5mm. The radius serves to avoid a notch effect and also the formation of a kind of bending joint. The width b of the rungs is 1 to 3 mm, preferably 2mm.
Für Stege mit a > 22mm liegt c im Bereich von 8 bis 18mm, bevorzugt 12mm. Die Höhe h in Höhenrichtung y beträgt 1,2 bis 2,4mm, bevorzugt 1,8mm. Der Steg ist aus PA66GF25 ausgebildet.For webs with a> 22mm c is in the range of 8 to 18mm, preferably 12mm. The height h in the vertical direction y is 1.2 to 2.4 mm, preferably 1.8 mm. The bridge is made of PA66GF25.
Fig. 8 c) zeigt eine Modifikation der sechsten Ausführungsform im Querschnitt, bei der der Verlauf des Steges zwischen den beiden Einrollköpfen nicht geradlinig, wie in Fig. 8 b) ist.Fig. 8 c) shows a modification of the sixth embodiment in cross section, in which the course of the web between the two curl heads is not rectilinear, as in Fig. 8 b).
Fig. 8 d) zeigt eine siebente Ausführungsform. Die siebente Ausfuhrungsform unterscheidet sich von der sechsten Ausführungsform dadurch, dass die Ausnehmungen nicht im Wesentlichen dreieckig, sondern im Wesentlichen rechteckig sind. Der Querschnitt senkrecht zur Längsrichtung kann wie in den Fig. 8 b) oder c) gezeigt sein. Die Maßangaben für a, b, c, e oder R zur sechsten Ausführungsform gelten auch für die siebente Ausführungsform. Das Maß d, d.h. die Ausdehnung der Ausnehmungen in Längsrichtung z liegt im Bereich von 3 bis 8mm, bevorzugt 5mm. Dieses Maß d gilt auch für die bevorzugte maximale Ausdehnung der dreieckigen Ausnehmungen in der sechsten Ausführungsform, auch wenn das Maß d in Fig. 8 a) nicht gezeigt ist.Fig. 8d) shows a seventh embodiment. The seventh embodiment differs from the sixth embodiment in that the recesses are not substantially triangular, but substantially rectangular. The cross section perpendicular to the longitudinal direction can be shown as in FIGS. 8 b) or c). The dimensions for a, b, c, e or R to the sixth embodiment also apply to the seventh embodiment. The dimension d, i. the extent of the recesses in the longitudinal direction z is in the range of 3 to 8 mm, preferably 5 mm. This dimension d also applies to the preferred maximum extent of the triangular recesses in the sixth embodiment, even if the dimension d in FIG. 8 a) is not shown.
Fig. 8 e) zeigt eine achte Ausführungsform. Die achte Ausführungsform unterscheidet sich von der sechsten und siebenten Ausfuhrungsform dadurch, dass die Ausnehmungen kreisförmig mit einem Durchmesser mit dem Maß c sind. Fig. 8 f) zeigt eine neunte Ausführungsform, die sich von der sechsten und siebenten Ausführungsform dadurch unterscheidet, dass die Ausnehmungen sechseckig sind. Die übrigen Angaben zu der sechsten und siebenten Ausführungsform gelten, soweit anwendbar, auch für die achte und neunte Ausführungsform.Fig. 8 e) shows an eighth embodiment. The eighth embodiment differs from the sixth and seventh embodiments in that the recesses are circular with a diameter of dimension c. Fig. 8 (f) shows a ninth embodiment which differs from the sixth and seventh embodiments in that the recesses are hexagonal. The remaining details of the sixth and seventh embodiments apply, as applicable, also for the eighth and ninth embodiments.
Fig. 9 zeigt in a) in der Draufsicht senkrecht zur Längsrichtung und in b) im Querschnitt zur Längsrichtung einen Isoliersteg mit einer sogenannten Package-Konstruktion. Diese Package- Konstruktion ist dazu gedacht, in ein Verbundprofil, wie es beispielhaft in Fig. 7 c) im Querschnitt gezeigt ist, eingebaut zu werden. Die vier Einrollköpfe 25 werden dabei in die entspre- chenden vier Aufnahmen eingerollt, wie es aus dem Vergleich mit der Fig. 7 ohne weiteres ersichtlich ist. Das in Fig. 9 b) obere Isolierstegteil 20a wird dabei in Fig. 7 c) oben und das in Fig. 9 b) untere Isolierstegteil 20b wird dabei in Fig. 7 c) unten eingerollt. Die beiden Isolierstegteile sind durch ein angeclipstes Verbindungsstück 20c so verbunden, dass einerseits eine Abschirmung gegen Konvektion und Strahlung zwischen Innen- und Außenseite des Verbundprofils erzielt wird, und dass andererseits mehrere Hohlkammern 2Od gebildet werden. Die Hohlkammern 2Od sind dabei durch eine Diagonalstrebe 2Oe des Verbindungsteils 20c in Höhenrichtung y unterteilt. Wie in Fig. 9 a) gut zu erkennen ist, können Ausnehmungen 24 mit einer Breite in Querrichtung x und in einer Längsausdehnung d in Längsrichtung z einen oder mehreren Isolierstegteile 20a, 20b und/oder dem Verbindungsteil 20c ausgebildet sein. Die in Fig. 9 d) gezeigten Isolierstegteile 20a und 20b weisen jeweils noch nach außen gerichtete Vorsprünge 2Of, die Aufnahmen für Gummidichtungen und/oder Beschlagsteile bilden können. Diese sind kein wesentlicher Bestandteil der gezeigten Ausführungsform. Die Zahl der Ausnehmungen und die Breite und Länge der Ausnehmungen ist nicht auf die in Fig. 9 a) gezeigte Anordnung beschränkt.Fig. 9 shows in a) in plan view perpendicular to the longitudinal direction and in b) in cross section to the longitudinal direction of an insulating web with a so-called package construction. This package construction is intended to be installed in a composite profile, as shown by way of example in Fig. 7 c) in cross-section. The four roll-in heads 25 are placed in the corresponding four shots curled, as it is readily apparent from the comparison with FIG. 7. The upper insulating web part 20a in FIG. 9b) is rolled up in FIG. 7c) and the lower insulating web part 20b in FIG. 9b is rolled down in FIG. 7c). The two Isolierstegteile are connected by a clipped connection piece 20c so that on the one hand a shield against convection and radiation between the inside and outside of the composite profile is achieved, and that on the other hand, a plurality of hollow chambers 2Od are formed. The hollow chambers 2Od are divided by a diagonal brace 2Oe of the connecting part 20c in the vertical direction y. As can be clearly seen in FIG. 9 a), recesses 24 having a width in the transverse direction x and in a longitudinal extent d in the longitudinal direction z can be formed one or more insulating web parts 20a, 20b and / or the connecting part 20c. The Isolierstegteile 20a and 20b shown in Fig. 9 d) each have still outwardly directed projections 2Of, which can form receptacles for rubber seals and / or fitting parts. These are not an essential part of the embodiment shown. The number of recesses and the width and length of the recesses is not limited to the arrangement shown in Fig. 9 a).
Die in Fig. 10 gezeigte Ausführungsform mit Modifikationen zeigt ein sogenanntes Hohl- kammerprofü. Bei einem solchen Hohlkammerpro fil befindet sich in Querrichtung x zwischen den Einrollvorsprüngen 25 Hohlkammern. In Fig. 10 d) ist der Querschnitt eines herkömmlichen Hohlkammerprofils gezeigt. Wie sich aus dem Vergleich mit dem Querschnitt der elften Ausführungsform in Fig. 10 b) ohne weiteres ergibt, besteht der Unterschied im Wesentlichen darin, dass in der mittleren Hohlkammer zwischen den Sprossen 23 die Wand entfernt ist, also Ausnehmungen 24 ausgebildet sind. Die Ausnehmungen weisen eine Breite g in Querrichtung x und eine Längsausdehnung d in Längsrichtung z auf. Insbesondere für Hohlkammerprofile mit einer Breite a von > 25mm können die Angaben zu c) der sechsten bis neunten Ausführungsform auch für g) verwendet werden. Bei den Modifikationen in Fig. 10 c) ist nur auf einer Seite der Hohlkammern eine Ausnehmung 24 ausgebildet. Entsprechend der Modifikationen, die in Fig. 10 e) und f) gezeigt wird, wird der Teil des Hohlkammerprofils, in dem eine oder mehrere Ausnehmungen 24 ausgebildet sind, mit einem Schaum als Füllmaterial gefüllt. Dieser Schaum ist bevorzugt ein pur-Schaum, der einen niedrigeren Wärmeleitungskoeffizienten als das zur Ausbildung des Isolierstegkörpers ausgebildete Material aufweist. Die Fig. I I a) bis f) zeigen Modifikationen der sechsten bis neunten Ausfuhrungsform in Ansichten mit gleicher Nummerierung a) bis f), bei denen jeweils ein Vorsprung 28 ausgebildet ist, der im Wesentlichen in Höhenrichtung y von dem Isolierstegkörper ausgehend vorsteht. Dieser Vorsprung 28 dient vornämlich zur Behinderung von Konvektion und Strahlung. Die Höhe des Vorsprungs 8 in Höhenrichtung y wird entsprechend gewählt. In Fig. 7 c) ist unten gestrichelt der Einbau eines Isolierstegs mit einem solchen Vorsprung 28 angedeutet. Wenn der in Fig. 7 c) obere Isoliersteg einen oder mehrere entsprechende Vorsprünge 28 aufweist, die in Querrichtung x gesehen mit dem unteren Vorsprung 28 überlappen, dann ist eine besonders effektive Behinderung der Konvektion und Strahlung erreicht. Die Fig. 12 b), c) und d) zeigen Modifikationen von Isolierstegen mit zwei solchen Vorsprüngen 28.The embodiment shown in FIG. 10 with modifications shows a so-called hollow chamber profile. In such a Hohlkammerpro fil is in the transverse direction x between the Einrollvorsprüngen 25 hollow chambers. In Fig. 10d), the cross section of a conventional hollow chamber profile is shown. As is apparent from the comparison with the cross section of the eleventh embodiment in Fig. 10 b) readily, the difference is essentially that in the middle hollow chamber between the rungs 23, the wall is removed, so recesses 24 are formed. The recesses have a width g in the transverse direction x and a longitudinal extent d in the longitudinal direction z. In particular, for hollow chamber profiles with a width a of> 25mm, the information on c) of the sixth to ninth embodiment can also be used for g). In the modifications in Fig. 10 c), a recess 24 is formed only on one side of the hollow chambers. According to the modifications shown in Figs. 10 (e) and (f), the part of the hollow chamber profile in which one or more recesses 24 are formed is filled with a foam as filler. This foam is preferably a pure foam, which has a lower coefficient of thermal conductivity than the material formed to form the Isolierstegkörpers. Fig. II a) to f) show modifications of the sixth to ninth embodiment in views with the same numbering a) to f), in each of which a projection 28 is formed, which protrudes substantially in the vertical direction y starting from the Isolierstegkörper. Namely, this projection 28 serves to hinder convection and radiation. The height of the projection 8 in the height direction y is selected accordingly. In Fig. 7 c) dashed lines the installation of an insulating bar with such a projection 28 is indicated. If the upper insulating web in Fig. 7 c) has one or more corresponding projections 28 which overlap with the lower projection 28 in the transverse direction x, then a particularly effective obstruction of the convection and radiation is achieved. FIGS. 12 b), c) and d) show modifications of insulating bars with two such projections 28.
Alle der in den Fig. 8 bis 12 gezeigten Ausführungsformen sind bevorzugt mit anextrudierten Deckeln der in Fig. 5, 6 gezeigten Art oder noch bevorzugter mit Clipsvorsprüngen und/oder Clipsaufnahmen der in Fig. 7 gezeigten Art vorgesehen. Alternativ ist es auch möglich, Folien zur Abdeckung der Ausnehmungen vorzusehen oder ein Ausschäumen mit einem Material geringerer Wärmeleitfähigkeit als das Material der Isolierstegkörper vorzunehmen. Bevorzugt sind dabei die wenigstens teilweise oder ganz angeclipsten Deckel oder ggf. Folien.All of the embodiments shown in FIGS. 8 to 12 are preferably provided with anextruded lids of the type shown in FIGS. 5, 6 or more preferably with clip projections and / or clip receivers of the type shown in FIG. Alternatively, it is also possible to provide foils to cover the recesses or to perform a foaming with a material of lower thermal conductivity than the material of the Isolierstegkörper. Preference is given to the at least partially or completely clipped lid or possibly films.
Als Material für die Isolierstegkörper kommen Hart-PVC, PA, PET, PPT, PA/PPE, ASA, PA66 in Frage, und bevorzugt wird PA66GF25. Als Schäume kommen Schäume aus Duroplasten wie PU mit entsprechender Dichte in Frage, bevorzugt Schäume niedriger Dichte (0,01 bis 0,3 kg/1).As the material for the Isolierstegkörper come hard PVC, PA, PET, PPT, PA / PPE, ASA, PA66 in question, and PA66GF25 is preferred. Suitable foams are foams made of thermosetting plastics such as PU with the appropriate density, preferably foams of low density (0.01 to 0.3 kg / l).
Frühere Anwendungen von leiterartigen Profilen zielten darauf ab, eine niedrige Schubfestigkeit (hohe Längsbeweglichkeit) zu erzielen. In einer anderen Anwendung wurden Ausnehmungen nur vorgesehen, um bei einer bekanntermaßen sehr stark leitenden Metalleinlage die Wärmeleitung zu verringern.Earlier applications of ladder-type profiles aimed to achieve low shear strength (high longitudinal mobility). In another application, recesses have been provided only to reduce heat conduction in a known highly conductive metal insert.
Bei den bevorzugten Ausführungsformen mit teilweise anextrudierten und auf der anderen Seite angeclipsten, bei den besonders bevorzugten Ausführungsformen mit vollständig angeclipsten Deckeln, und auch bei den Ausführungsformen mit angeklebten oder auflaminierten Folien, jeweils zur Abdeckung der Ausnehmungen, hat sich insbesondere für die ganz oder teilweise angeclipsten Deckel überraschender Weise herausgestellt, dass diese die sogenann- ten U- Werte, d.h. die Wärmetrennungseigenschaften der Isolierstege gegenüber nicht abgedeckten Versionen nur unwesentlich beeinflussen. So haben Versuche mit einem massiven Steg mit einem Querschnitt der in Fig. 8 b) gezeigten Art, d.h. einem Steg ohne Ausnehmungen, der eine Breite von 25mm und eine Höhe h von 1 ,8mm und als Material PA26GF25 aufwies, einen U- Wert (W/m2K) von 2,4 ergeben.In the preferred embodiments with partially extruded and clipped on the other side, in the most preferred embodiments with fully clipped lids, and also in the embodiments with glued or laminated foils, each for covering the recesses, has been clipped in particular for the wholly or partially Cover surprisingly found that these are the so-called ten U values, ie the heat separation properties of the insulating bars against uncovered versions affect only slightly. Thus, experiments with a solid web having a cross-section of the type shown in Fig. 8b), ie a web with no recesses, having a width of 25mm and a height h of 1, 8mm and material PA26GF25, have a U-value ( W / m 2 K) of 2.4.
Ein Isoliersteg der in Fig. 8 d) gezeigten Art mit c = 8mm und d = 5mm und b = 2mm ergab ohne Abdeckung einen U-Wert 2,15 WAn2K. Ein entsprechender Steg mit gemäß Fig. 7 an- geclipsten Deckeln hatte einen U-Wert von 2,25 W/m2K. Die Messungen wurden in einer sogenannten „Hot-Box" durchgeführt, wobei als Ausgangssystem ein System mit 25mm breiten, flachen Isolierstegen eingesetzt wurde, die im Rahmen des Versuchs nicht getauscht wurden. In der Realität sollten die Verbesserungen der U- Werte daher noch besser sein.An insulating bar of the type shown in FIG. 8 d) with c = 8 mm and d = 5 mm and b = 2 mm gave a U value of 2.15 mm 2 K. Without cover, it had a corresponding bar with lids clipped in according to FIG a U-value of 2.25 W / m 2 K. The measurements were carried out in a so-called "hot box", with a system with 25mm wide, flat insulating bars was used as the starting system, which were not exchanged in the experiment. In reality, the improvements in U-values should be even better.
Auch wenn der Grund dieses Effektes nicht ganz klar ist, so liegt er doch vermutlich in der Ausgestaltung der Clipsanschlüsse und damit des stark behinderten Wärmeübertragungsweges durch den Deckel.Although the reason of this effect is not very clear, it probably lies in the design of the clip connections and thus the strongly impeded heat transfer path through the lid.
Für die in den Fig. 9, 10 gezeigten Ausführungsformen mit Hohlkammern, die bereits für Systeme mit sehr guten Isolierungseigenschaften eingesetzt werden, können diese Eigenschaften weiter verbessert werden. Das Verwenden von Konvektions- und/oder Strahlungsabschir- mungsvorsprüngen 28 erhöht die Wirkung ebenfalls.For the embodiments shown in FIGS. 9, 10 with hollow chambers, which are already used for systems with very good insulation properties, these properties can be further improved. The use of convection and / or radiation shielding projections 28 also increases the effect.
