Description

Die Neuerungen betreffen thermisch getrennte Vebundprofile für Konstruktionen von Klimageräten und Klimazentralen.The innovations concern thermally separated composite profiles for the construction of air conditioning units and air conditioning centers.

Da Metalle sehr gute Wärmeleiter sind, ist es zur Vermeidung von Energieverlusten von großer Wichtigkeit, die sogenannte Kältebrücke bei den Rahmenprofilen für Klimageräte usw. deren Profile aus Metall bestehen, diese thermisch zu trennen. Diese bestehen in der Regel aus zwei Metallprofilen, die durch einen dazwischen liegenden Kunststoff oder einem Gummi mit guten Wärmeisoliereigenschaften voneinander getrennt und zueinander mechanisch verbunden sind.Since metals are very good conductors of heat, it is very important to avoid energy losses by thermally separating the so-called cold bridge in the frame profiles for air conditioning units, etc. whose profiles are made of metal. These usually consist of two metal profiles that are separated from each other by a plastic or rubber with good thermal insulation properties in between and are mechanically connected to each other.

Eine ähnliche Verbindung ist aus der P 28 42 333.8 bekannt, die aus zwei Aluminiumprofilen besteht, die durch zwei profilierte Isolierleisten miteinander mechanisch verbunden werden.A similar connection is known from P 28 42 333.8, which consists of two aluminium profiles that are mechanically connected to each other by two profiled insulating strips.

Eine weitere Verbindung ist aus der GM 75 15 089 bekannt, die ebenfalls aus zwei Aluminiumprofilen besteht und auch durch zwei profilierte Isolierleisten miteinander verbunden werden.Another connection is known from GM 75 15 089, which also consists of two aluminum profiles and is also connected to each other by two profiled insulating strips.

Da die vorgenannten Verbindungen mit der Neuerung nur den Charakter der thermischen Trennung gemeinsam haben und sich ansonsten von den Materialien, den Zusammenbau und dem Einsatzgebiet erheblich unterscheiden, wird eine Gegenüberstellung nicht weiterbehandelt.Since the above-mentioned connections only have the character of thermal separation in common with the innovation and otherwise differ considerably in terms of materials, assembly and area of application, a comparison will not be discussed further.

Eines mit der Neuerung zu vergleichendes Verbundprofil ist beispielsweise aus der G 83 08 856.3 bekannt.A composite profile comparable with the new version is known, for example, from G 83 08 856.3.

Ein Nachteil dieser Ausführung eines Verbundprofiles ist, daß es aus zuvielen Profilteilen, einem Träger- einem Deckprofil und den Kunststoffisolierleisten besteht.A disadvantage of this design of a composite profile is that it consists of too many profile parts, a carrier profile, a cover profile and the plastic insulation strips.

Ein weiterer Nachteil ist, daß die einzelnen Profilteile miteinander keine Verankerung aufweisen und somit keine kraftschlüssige Verbindung gewährleistet, keine geschlossene Einheit bilden und auf Zugbelastung nur bedingt beansprucht werden können.A further disadvantage is that the individual profile parts are not anchored to one another and therefore do not guarantee a force-locking connection, do not form a closed unit and can only be subjected to tensile loads to a limited extent.

Außerdem ist es ein Nachteil, um der Festigkeit gerecht zu werden, müssen die Kunststoffteile eine aus kostengründen nicht zuvertretende Dimensionierung annehmen.Another disadvantage is that in order to meet the required strength, the plastic parts must be dimensioned in a way that is not justifiable for cost reasons.

Ein weiterer Nachteil ist der Zusammenbau des Verbundprofiles von vier Profilteilen, 1 Träger - 1 Deckprofil und 2 Kunststoffprofilen, montageunfreundlich durch zusammenschieben, kostenintensiv.Another disadvantage is the assembly of the composite profile from four profile parts, 1 support - 1 cover profile and 2 plastic profiles, difficult to assemble by pushing them together, costly.

Aus der DE - GM 75 15 089 ist ein anderes Verbundprofil aus Aluminium strangepresstem Profil thermisch getrennt bekannt.Another composite profile made of thermally separated extruded aluminum is known from DE - GM 75 15 089.

Diese Verbundprofile unterscheiden sich insofern von der Neuerung, daß sie wie G 83 08 856.3 aus mehreren Profilteilen zusammen montiert werde müßen und somit montageunfreundlich und kostenintensiv sind.These composite profiles differ from the new version in that, like G 83 08 856.3, they have to be assembled from several profile parts and are therefore difficult to assemble and costly.

Ein weiterer Nachteil gegenüber der Neuerung ist, auf Grund des eingesetzten Materials, bei gleichem Querschnitt die erreichbaren geringeren statischen Werte.A further disadvantage compared to the innovation is the lower static values that can be achieved with the same cross-section due to the material used.

Aufgabe ist es die Neuerung so zu beschaffen, daß die Verbundprofile thermisch getrennt, einfach und kostengünstig herstellbar, witterungsbeständig und den statischen Ansprüchen gerecht werden.The task is to create the innovation in such a way that the composite profiles are thermally separated, easy and cost-effective to manufacture, weather-resistant and meet the static requirements.

Gelöst werden die gestellten Aufgaben mit den Merkmalen des Schutzanspruches 1. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.The tasks set are solved with the features of the protection claim 1. Advantageous further developments are specified in the subclaims.

Die Neuerungen werden anhand der nachfolgenden Zeichnungen näher erläutert.The innovations are explained in more detail using the following drawings.

Mit Fig. 1 ist das Verbundprofil als Eckpfosten dargestellt, das aus zwei bandbeschichteten Profilen 1+2 und zwei Kunststoff prof ilen 5 hergestellt ist. Die Bandbeschichtung DX 51 DZ 275 NA-C gewährleistet gegen Witterungseinflüsse innen und außen einen Schutz. Unter Verwendung von Haftmitteln kann eine Farbgestaltung mit herkömmlichen Mitteln aufgebracht werden. Beide Profile werden aus Spaltband im kaltwalzverfahren hergestellt. Das Eckprofil 1,2 + 5 ist ein in sich geschlossenes Hohlprofil und weist ein hohes Widerstandsmoment auf. Im Dachbereich wird das Profil auf Durchbiegung und ansonsten auf Druck belastet.Fig. 1 shows the composite profile as a corner post, which is made from two strip-coated profiles 1+2 and two plastic profiles 5. The strip coating DX 51 DZ 275 NA-C ensures protection against the effects of the weather inside and out. By using adhesives, a color design can be applied using conventional means. Both profiles are made from slit strip using the cold rolling process. The corner profile 1,2 + 5 is a self-contained hollow profile and has a high section modulus. In the roof area, the profile is subjected to deflection and otherwise to pressure.

Mit Fig. 2 ist das Verbundprofil als Mittelpfosten dargestellt, das ebenfalls aus zwei bandbeschichteten Profilen 3 + 4 und zwei Kuststoff prof ilen 5 hergestellt ist. Die Bandbeschichtung und die Farbgestaltung ist auch wie beim Eckprofil gewährleistet.Fig. 2 shows the composite profile as a center post, which is also made from two strip-coated profiles 3 + 4 and two plastic profiles 5. The strip coating and the color design are also guaranteed as with the corner profile.

Ebenso wie beim Eckprofil bilden die Profile 3,4 und 5 ein in sich geschlossenes Hohlprofil und weist ebenfalls ein hohes Widestandsmoment auf. Die Lastbeanspruchung verhält sich wie beim Eckprofil.As with the corner profile, profiles 3, 4 and 5 form a self-contained hollow profile and also have a high section moment. The load stress behaves in the same way as with the corner profile.

Mit Fig. 3 ist ein Klimagerät mit den Verbundprofilen als Schemaskizze,dargestellt. Fig. 3 shows an air conditioning unit with the composite profiles as a schematic sketch.

Mit den beiden neuen Verbundprofilen ist ein witterungsbeständiges, einfach herstellbares, thermisch getrenntes Profilsystem aus Stahl entstanden, das sich durch eine hohe Steifigkeit auszeichnet und sich durch schweißen oder durch Steckverbinder verbinden läßt.The two new composite profiles create a weather-resistant, easy-to-manufacture, thermally separated profile system made of steel that is characterized by high rigidity and can be connected by welding or using connectors.
