Abstract

In the profile member (1, 2), in which the insulating zone is formed by plastics strips (3, 4) or blocks, thin-walled plastics profile members (8) are inserted into the air chambers (10) produced between the metal profile members (1, 2) in order to divide the air chambers (10) into subchambers so as thereby to increase the thermal insulation. <IMAGE>

Description

Die Erfindung betrifft ein wärmegedämmtes Profil aus Metall, insbesondere Aluminium, bei dem die Dämmzone durch Leisten oder Klötze aus Kunststoff gebildet wird.The invention relates to a thermally insulated profile made of metal, in particular aluminum, in which the insulation zone is formed by strips or blocks of plastic.

Es ist bekannt, bei Metallfenstern zur Vermeidung der Kältebrücke das innere und äußere Metallprofil durch Kunststoffe zu distanzieren. Der Kunststoff kann dabei in Form von durchlaufenden Leisten, Schaumbrücken oder durch willkürlich einsetzbare Kunststoffklötze erfolgen, die in Abständen entsprechend den statischen Erfordernissen angeordnet werden. Im ersteren und letzteren Fall ergeben sich dabei Luftzwischenräume, deren Wärmedämmung durch innere Zirkulation verschlechtert wird und daher bei größeren Zwischenräumen keine wesentlich bessere Wärmedämmung bringen.It is known in metal windows to avoid the cold bridge by spacing the inner and outer metal profile with plastics. The plastic can be made in the form of continuous strips, foam bridges or by arbitrarily usable plastic blocks, which are arranged at intervals according to the static requirements. In the former and the latter case there are air gaps, the thermal insulation of which is impaired by internal circulation and therefore do not bring much better thermal insulation for larger gaps.

Dies wird erfindungsgemäß dadurch verhindert, daß in die Luftkammer zur Erhöhung der Wärmedämmung ein dünnwandiges Kunststoffprofil eingesetzt ist, welches die Luftkammer in zwei oder mehrere Teilkammern aufteilt.This is prevented according to the invention in that a thin-walled plastic profile is inserted into the air chamber to increase the thermal insulation, which is the air chamber divided into two or more compartments.

Durch diese Unterteilung der Luftkammer beschränkt sich die Zirkulation jeweils auf eine Teilkammer und der Wärmefluß muß damit mehrere Zwischenwände überwinden.Due to this subdivision of the air chamber, the circulation is limited to one sub-chamber and the heat flow must overcome several partition walls.

Der Gegenstand der Erfindung ist in der Zeichnung beispielsweise dargestellt. Es zeigen:

  • Fig. 1 einen Querschnitt eines Verbundprofiles, das mittels durchlaufender Kunststoffstege verbunden ist,
  • Fig. 2 einen Querschnitt eines Verbundprofiles, das durch Distanzklötze verbunden ist,
  • Fig. 3 dasselbe Profil mit zwischen den Distanzklötzen eingelegtem Kunststoffprofil,
  • Fig. 4, 5, 6, 7, 8 und 9 verschiedene Querschnittsformen der dünnwandigen Kunststoffprofile.
The object of the invention is shown for example in the drawing. Show it:
  • 1 shows a cross section of a composite profile which is connected by means of continuous plastic webs,
  • 2 shows a cross section of a composite profile which is connected by spacer blocks,
  • 3 shows the same profile with a plastic profile inserted between the spacer blocks,
  • 4, 5, 6, 7, 8 and 9 different cross-sectional shapes of the thin-walled plastic profiles.

Wie man aus der Zeichnung erkennen kann, werden zwei Leichtmetallprofile 1 und 2 mittels durchlaufender Kunststoffleisten 3 und 4 verbunden, welche mit ihren verdickten Enden in hinterschnittenen oder zusammengebogenen Nuten der Leichtmetallprofile 1 und 2 gehalten sind, so daß eine form- und kraftschlüssige Verbindung gegeben ist, die allen festigkeitstechnischen Anforderungen genügt. In die zwischen den Leisten 3 und 4 gebildete Luftkammer 10 wird ein dünnwandiges, im Querschnitt etwa H-förniges Profil 8 aus Kunststoff eingeschoben, welches diese Luftkammer in mindestens vier Kammern unterteilt, wodurch eine Zirkulation zwischen diesen Kammern verhindert wird. Gemäß den Figuren 2 und 3 erfolgt das Einlegen des dünnwandigen Kunststoffprofiles 8 in die Zwischenräume zwischen den Distanzhlötzen 5 und den Abdeckleisten 6 und 7, die ebenfalls aus wärmedämmendem Material bestehen. Das wärmedämmende Kunststoffprofil 8 besteht aus dünnem elastischen Werkstoff, so daß es mit den Enden seiner Schenkel 9 an den Leichtmetallprofilen 1 und 2 unter elastischer Spannung anliegt und damit eine gewisse Abdichtung der einzelnen Luftkammern bewirkt. Das Kunststoffprofil kann daher auch als Strangpreßprofil in großen Längen hergestellt und für Transportzwecke eingerollt oder geknickt werden, da es unter Umständen auch noch auf der Baustelle abgelängt und eingesetzt werden kann. Es ist nicht auf die H-förmige Ausführungsform beschränkt, sondern kann gemäß der Fig. 4 auch mit drei Flanschen, gemäß Fig. 5 als X-Profil, gemäß den Fig. 6 und 7 als Netzprofil, nach Fig. 8 mit drei Flanschen als stehendes Profil und Fig. 9 als Zickzack- oder Wellprofil ausgebildet sein. Zur Verbesserung der Wärmedämmung kann es auch mit Aluminium oder dergleichen reflektierend oberflächenbeschichtet sein, um Wärmeverluste durch Strahlung zu vermeiden. Da die Profile parallel zur Profillängsachse eingelegt sind, können die Kanäle beim Eloxiervorgang leicht durchgespült werden.As can be seen from the drawing, two light metal profiles 1 and 2 are connected by means of continuous plastic strips 3 and 4, which are held with their thickened ends in undercut or bent grooves of the light metal profiles 1 and 2, so that there is a positive and non-positive connection that meets all strength requirements. In the air chamber 10 formed between the strips 3 and 4 is inserted a thin-walled, approximately H-shaped profile 8 made of plastic, which divides this air chamber into at least four chambers, thereby preventing circulation between these chambers. According to Figures 2 and 3, the insertion of the thin-walled plastic profile 8 in the spaces between the spacer 5 and the cover strips 6 and 7, which also consist of heat-insulating material. The insulating plastic profile 8 is made of thin elastic material, so that it ends his leg 9 rests on the light metal profiles 1 and 2 under elastic tension and thus causes a certain sealing of the individual air chambers. The plastic profile can therefore also be manufactured as an extruded profile in large lengths and rolled or folded for transport purposes, since under certain circumstances it can also be cut to length and used on the construction site. It is not limited to the H-shaped embodiment, but can, according to FIG. 4, also with three flanges, according to FIG. 5 as an X profile, according to FIGS. 6 and 7 as a net profile, according to FIG. 8 with three flanges as standing profile and Fig. 9 can be designed as a zigzag or corrugated profile. To improve the thermal insulation, it can also have a reflective surface coating with aluminum or the like in order to avoid heat losses due to radiation. Since the profiles are inserted parallel to the longitudinal axis of the profile, the channels can be easily rinsed out during the anodizing process.
