Abstract

The hollow profiled metal bar, esp. made of aluminium is for use in double-glazing, and has a lengthwise weld seam (12a). The seam is formed in a retracted portion of the profile, where it is concealed. There can also be a second retracted portion (8b) on the opposite side of the bar, and which is a mirror image of the first one (8). The bar can have two parallel sidewalls (6), and two other walls (7) at right angles to them with the retracted portions form ed in them and running centrally in the lengthwise direction.

Description

Die Erfindung betrifft ein Sprossenhohlprofil aus Metall, insbesondere als Aluminium, für Isolierverglasungen sowie ein Verfahren zur Herstellung des Sprossenhohlprofils.The invention relates to a hollow hollow profile made of metal, in particular as aluminum, for insulating glazing and to a method for producing the hollow hollow profile.

Sprossen in Isolierverglasungen werden zwischen zwei Glasscheiben von z. B. Fenstern angeordnet. Die Sprossen bestehen aus Hohlprofilstangen, die z. B. mittels Kreuzverbindungsstücken, zusammengesteckt sind und mit Verbindungsstopfen mit dem Abstandhalterrahmen der Isolierverglasung in Verbindung stehen. Die Sprossen haben entweder die Metallfarbe oder sie sind mit Farbe beschichtet, wobei die Farbe der Sprossen meist der Farbe der Fensterrahmen angepaßt ist.Rungs in double glazing are between two panes of e.g. B. windows arranged. The rungs consist of hollow profile rods, the z. B. are plugged together by cross connectors and are connected with plugs to the spacer frame of the double glazing. The rungs either have the metal color or they are coated with paint, whereby the color of the rungs is usually matched to the color of the window frame.

Bei einem bekannten Verfahren zur Herstellung einer Sprosse wird eine Hohlprofilstange als geschlossenes Profil extrudiert. Bei dieser Herstellungsweise ist eine verhältnismäßig dicke Wandung für die Hohlprofilstange vorgegeben, weil dünne Wandstärken mit einem vertretbaren Aufwand nicht extrudierbar sind. Für eine solche Sprosse wird somit relativ viel Material verbraucht. Ein weiterer Nachteil ist, daß eine äußere Beschichtung der Hohlprofilstange aufwendig ist, weil die Beschichtung erst nach der Profilierung erfolgen kann.In a known method for producing a rung, a hollow profile rod is extruded as a closed profile. In this production method, a relatively thick wall is specified for the hollow profile rod, because thin wall thicknesses cannot be extruded with a reasonable effort. A relatively large amount of material is thus used for such a rung. Another disadvantage is that an outer coating of the hollow profile rod is complex because the coating can only be done after profiling.

Bei einem anderen bekannten Verfahren zur Herstellung einer Sprosse wird aus einem Metallband eine Hohlprofilstange mit einer Stoßfuge geformt, die dann durch Verschweißung geschlossen wird.In another known method for producing a rung, a hollow profile rod with a butt joint is formed from a metal strip, which is then closed by welding.

Bei einer nach diesem Verfahren hergestellten Sprosse ist die Schweißnaht an der Oberfläche sichtbar, was optisch unschön ist. Durch eine Beschichtung kann zwar die Schweißnaht unsichtbar gemacht werden, das nachträgliche Beschichten ist aber ebenso aufwendig wie im Falle der extrudierten Sprossenhohlprofile. Außerdem ist der Farbverbrauch hoch, weil die Beschichtung die Schweißnaht so abdecken muß, daß die Schweißnaht unsichtbar wird. Ein Farbauftrag vor dem Schweißen ist nicht möglich, weil beim Schweißen die Farbe im Bereich der Schweißnaht verbrennen und das Hohlprofil unansehlich würde.In the case of a rung produced using this method, the weld seam is visible on the surface, which is optically unsightly. A coating can make the weld invisible, but subsequent coating is just as complex as in the case of extruded hollow hollow profiles. The ink consumption is also high because the coating has to cover the weld seam in such a way that the weld seam becomes invisible. It is not possible to apply paint before welding because during welding the paint burns in the area of the weld seam and the hollow profile would become unsightly.

Aufgabe der Erfindung ist, auf einfache Weise metallfarbene sowie farbig beschichtete Sprossenhohlprofile mit Schweißnaht zu schaffen, bei denen die Schweißnaht nicht störend wirkt und die trotz geringer Wandstärke relativ biege- und torsionssteif sind. Außerdem soll ein einfaches und wirtschaftliches Verfahren zur Herstellung dieses Sprossenhohlprofils angegeben werden.The object of the invention is to provide in a simple manner metal-colored and color-coated hollow rung profiles with a weld seam, in which the weld seam does not have a disruptive effect and which, despite the small wall thickness, are relatively resistant to bending and torsion. In addition, a simple and economical method for producing this hollow rung profile is to be specified.

Diese Aufgabe wird hinsichtlich des Sprossenhohlprofils durch die Merkmale des Anspruchs 1 und hinsichtlich der Herstellung dieses Sprossenhohlprofils durch die Merkmale des Anspruchs 8 gelöst. Vorteilahfte Weiterbildungen der Erfindung sind in den abhängigen Unteransprüchen angegeben.This object is achieved with regard to the hollow hollow profile by the features of claim 1 and with regard to the production of this hollow hollow profile by the features of claim 8. Advantageous developments of the invention are specified in the dependent subclaims.

Nachfolgend ist die Erfindung anhand der Zeichnungen näher erläutert; es zeigen:

The invention is explained in more detail below with reference to the drawings; show it:
Fig. 1
schematically a window with double glazing in the front view,
Fig. 2
a section along the line II-II in Fig. 1 in an enlarged view.

In der Fig. 1 ist ein Fenster 1 mit Isolierverglasung dargestellt. Die Erfindung betrifft jedoch nicht nur Sprossen für Sprossenfenster mit einer Isolierverglasung, sondern auch Sprossen für Isolierverglasungen schlechthin.In Fig. 1, a window 1 is shown with double glazing. However, the invention relates not only to rungs for lattice windows with insulating glazing, but also to rungs for insulating glazing par excellence.

Ein Fenster 1 mit einer Isolierverglasung weist im allgemeinen einen Fensterrahmen 2, wenigstens zwei auf Abstand angeordnete, im Fensterrahmen 2 gelagerte Glasscheiben 3 und einen die Glasscheiben 3 auf Abstand haltenden, mit Trockenmittel gefüllten Abstandhalterahmen 4 auf. Im Zwischenraum zwischen den Glasscheiben 3 sind Sprossen 5 angeordnet. Die Sprossen 5 bestehen aus Hohlprofilstangen aus Metall mit einer Längsschweißnaht 12a, die zu einem Kreuzungsgebilde zusammengesetzt sind. An den Kreuzungssstellen sind die Sprossen 5 in an sich bekannter Weise mit Kreuzverbindungsstücken zusammengesetzt (nicht dargestellt). Verbindungsstopfen übernehmen in an sich bekannter Weise die Lagerung der Sprossen 5 am Abstandhalterrahmen 4.A window 1 with insulating glazing generally has a window frame 2, at least two glass panes 3 arranged at a distance and stored in the window frame 2, and a spacer frame 4 which holds the glass panes 3 at a distance and is filled with desiccant. Rungs 5 are arranged in the space between the glass panes 3. The rungs 5 consist of hollow profile bars made of metal with a longitudinal weld 12a, which are assembled to form an intersection. At the crossing points, the rungs 5 are assembled in a manner known per se with cross connecting pieces (not shown). Connection plugs take over the mounting of the rungs 5 on the spacer frame 4 in a manner known per se.

Sprossen 5 können unterschiedliche Hohlprofilquerschnittsformen aufweisen. Dargestellt ist ein gängiges Profil, das parallel zu den Glasscheiben 3 angeordnete Seitenwandungen 6 und quer zu den Seitenwandungen 6 verlaufende Stirnwandungen 7 aufweist. Die Stirnwandungen 7 sind schmaler als die Seitenwandungen 6, weshalb ein vorzugsweise hohlkehlenförmiger Übergangsbereich 6a zwischen den Wandungen 6 und 7 vorgesehen ist.Rungs 5 can have different hollow profile cross-sectional shapes. A common profile is shown which has side walls 6 arranged parallel to the glass panes 3 and end walls 7 running transversely to the side walls 6. The end walls 7 are narrower than the side walls 6, which is why a preferably fillet-shaped transition region 6a is provided between the walls 6 and 7.

Wesentlich ist, daß in beiden Stirnwandungen 7, zweckmäßigerweise in deren Längsmitte, eine längsverlaufende Profileinziehung 8, 8b bzw. rillenförmige Einbuchtungen 9, 9a einprofiliert ist.It is essential that a longitudinal profile indentation 8, 8b or groove-shaped indentations 9, 9a is profiled in both end walls 7, expediently in the longitudinal center thereof.

Die Profileinziehungen 8, 8b sind gleichgeformt und spiegelbildlich zueinander angeordnet. Die Tiefe jeder Rille 9, 9a beträgt z. B. 1/8 bis 1/10 der Höhe des Profils (Abstand zwischen den Stirnwandungen 7). Die Breite der Rille 9, 9a soll möglichst gering sein, jedoch in jedem Fall so gering, daß der Rillenboden von außen unsichtbar bleibt. Vorzugsweise liegen die Seitenwandungen 8a der Rillen 9, 9a aneinander.The profile indentations 8, 8b have the same shape and are arranged in mirror image to one another. The depth of each groove 9, 9a is z. B. 1/8 to 1/10 of the height of the profile (distance between the end walls 7). The width of the groove 9, 9a should be as small as possible, but in any case so small that the bottom of the groove remains invisible from the outside. The side walls 8a of the grooves 9, 9a preferably lie against one another.

Die Sprossen 5 werden jeweils in der erforderlichen Länge von Hohlprofilstangen 11 abgelängt. Die Hohlprofilstangen 11 sind aus einem relativ dünnen Metallband, z. B. aus Aluminium geformt, wobei die Längskanten 12 des Metallbandes aufeinanderzu gebogen werden, so daß ein geschlossenes Rohr 11a geformt wird. Die Stoßkanten bzw. Längskanten 12 werden miteinander verschweißt, so daß eine Schweißnaht 12a entsteht. Die sich anschließende Profilierung erzeugt die Rillung 9, 9a derart, daß die Schweißnaht 12a in den Innenraum 5a des Profils verdrängt und unsichtbar wird. Damit die Sprosse 5 gleichförmig aussieht, ist nach einer zweckmäßigen Ausführungsform der Erfindung vorgesehen, daß der der Rille 9 mit der Schweißnaht 12 gegenüberliegende Bereich des Rohres 11a in gleicher Weise gerillt wird und die Rillung 9a enthält.The rungs 5 are cut to the required length by hollow profile rods 11. The hollow profile rods 11 are made of a relatively thin metal strip, e.g. B. formed of aluminum, wherein the longitudinal edges 12 of the metal strip are bent towards each other, so that a closed tube 11a is formed. The butt edges or longitudinal edges 12 are welded together, so that a weld seam 12a is formed. The subsequent profiling produces the grooves 9, 9a in such a way that the weld seam 12a is displaced into the interior 5a of the profile and becomes invisible. So that the rung 5 looks uniform, it is provided according to an expedient embodiment of the invention that the area of the tube 11a opposite the groove 9 with the weld seam 12 is grooved in the same way and contains the grooving 9a.

Die Sprosse 5 besteht - wie bereits erwähnt - vorzugsweise aus Aluminium. Die Wandstärke der Sprosse beträgt insbesondere etwa 0,4 bis 0,6 mm. Die Außenmantelfläche der Sprosse trägt vorzugsweise eine Farbschicht 6c oder ist eloxiert.As already mentioned, the rung 5 is preferably made of aluminum. The wall thickness of the rung is in particular about 0.4 to 0.6 mm. The outer lateral surface of the rung preferably carries a color layer 6c or is anodized.

Ein besonders einfaches Verfahren zur Herstellung einer Hohlprofilstange 11 ergibt sich aus Fig. 3. Ausgangsmaterial ist ein relativ breites Metallband 13, das von einem Breitbandcoil 14 abgezogen wird. Das Metallband 13 besteht z. B. aus Aluminium und trägt auf der Außenseite 13a eine relativ dünne Farbschicht 6c.A particularly simple method for producing a hollow profile rod 11 results from FIG. 3. The starting material is a relatively wide metal strip 13, which is pulled off from a broadband coil 14. The metal strip 13 consists, for. B. made of aluminum and carries a relatively thin layer of paint 6c on the outside 13a.

Das Metallband 13 wird während des Abziehens zunächst in mehrere Streifen 15 längsgeschnitten, aus denen vorzugsweise jeweils gleichzeitig Hohlprofilstangen 11 z. B. durch Rollverformung und/oder Prägung geformt werden. Die Streifen 15 können aber auch aufgerollt und später weiterverarbeitet werden. Die Hohlprofile 11, die aus den Streifen 15 geformt werden, können gleiche oder unterschiedliche Querschnittsformen aufweisen. Ebenso können die Streifen 15 gleich breit oder unterschiedlich breit sein.The metal strip 13 is first cut longitudinally into a plurality of strips 15 during the pulling process, from which preferably hollow profile rods 11 are z. B. formed by roll deformation and / or embossing. The strips 15 can also be rolled up and further processed later. The hollow profiles 11 which are formed from the strips 15 can have the same or different cross-sectional shapes. Likewise, the strips 15 can be the same width or different widths.

Die Aufteilung des Metallbandes 13 in mehrere Streifen 15 durch längsverlaufende Einschnitte 16 erfolgt an einer Bearbeitungsstation A, die das Metallband 13 beim Abziehen durchläuft. In Abzugsrichtung befindet sich hinter der Bearbeitungsstation A eine Bearbeitungsstation B mit Formgebungswerkzeugen (nicht dargestellt), in denen der Streifen 15 zu einem z. B. im Querschnitt kreisrunden Rohr 11a mit aneinanderstoßenden Längskanten 12 geformt wird. Die Farbschicht 6c befindet sich dabei auf der Außenmantelfäche des Rohres. An einer der Bearbeitungsstation B nachgeordneten Bearbeitungsstation C mit einer Schweißvorrichtung werden die Längskanten 12 zur Schweißnaht 12a verschweißt, vorzugsweise laserverschweißt. Hinter der Bearbeitungsstation C befindet sich eine Bearbeitungsstation D mit Formwerkzeugen (nicht dargestellt), mit denen die Profileinziehungen 8, 8b eingeformt werden und gleichzeitig oder nachfolgend auch die Profilierungen der Seitenwandungen 6, 6a und Stirnwandungen 7 geformt werden können.The division of the metal strip 13 into a plurality of strips 15 by longitudinal cuts 16 takes place at a processing station A which the metal strip 13 passes through when it is pulled off. In the take-off direction, there is a processing station B with shaping tools (not shown) behind the processing station A, in which the strip 15 forms a z. B. is formed in cross-section circular tube 11 a with abutting longitudinal edges 12. The color layer 6c is located on the outer surface of the tube. At a processing station C downstream of the processing station B with a welding device, the longitudinal edges 12 are welded to the weld seam 12a, preferably by laser welding. Behind the processing station C there is a processing station D with molding tools (not shown) with which the profile indentations 8, 8b are formed and, at the same time or subsequently, the profiles of the side walls 6, 6a and end walls 7 can also be formed.

Beim Schweißen verbrennt im Bereich der Schweißnaht 12a Farbe. Durch die erfindungsgemäße Profileinziehung im Bereich der Schweißnaht werden die Schweißnaht selbst sowie die durch die Hitze beim Schweißen beeinträchtigten Farbbereiche in der Rille 9 versteckt, so daß sie von außen unsichtbar bleiben. Durch diese ungewöhnliche Maßnahme wird erreicht, daß aus einem beschichteten Metallband geformte und geschweißte Hohlprofile als Sprossen verwendet werden können, ohne daß die Schweißnaht und die zum Teil verbrannten Farbbereiche optisch stören. Aber auch bei Verwendung unbeschichteter Metallbänder können Sprossen geformt werden, deren Schweißnaht versteckt ist und nicht optisch störend wirkt.During welding, paint burns in the area of the weld 12a. Due to the profile retraction according to the invention in the area of the weld seam, the weld seam itself and the color areas affected by the heat during welding are hidden in the groove 9, so that they remain invisible from the outside. This unusual measure ensures that hollow profiles formed and welded from a coated metal strip can be used as rungs without the weld seam and the partially burned color areas visually disturbing. But even when using uncoated metal strips, rungs can be formed, the weld seam of which is hidden and does not have a visual effect.

Die kontinuierlich hergestellten Hohlprofilstangen 11 werden auf geeignete Handelslängen abgelängt und stehen als Zwischenprodukt dem Hersteller von Isolierverglasungen zur Verfügung. Der Hersteller längt die Sprossen 5 von der Hohlprofilstange 11 ab und bildet die gewünschten Sprossenkonfigurationen für eine Isolierverglasung.The continuously produced hollow profile rods 11 are cut to suitable commercial lengths and are available to the manufacturer of insulating glazing as an intermediate product. The manufacturer cuts the rungs 5 from the hollow profile rod 11 and forms the desired rung configurations for double glazing.

Die Erfindung lehrt somit, zumindest eine Profileinziehung zur Unsichtbarmachung einer Schweißnaht vorzusehen und schlägt aus optischen Gründen vor, zumindest eine weitere Profileinziehung spiegelbildlich zur Profileinziehung mit der Schweißnahnt anzuordnen. Dabei muß die Schweißnaht nicht an einer Stirnseite angeordnet sein. Sie kann vielmehr z. B. auch an einer Seitenwandung liegen, wenn die optischen Anforderungen an das Sprossenprofil dies zulassen.The invention thus teaches to provide at least one profile indentation for making a weld seam invisible and, for optical reasons, proposes to arrange at least one further profile indentation in mirror image for the profile indentation with the weld seam. The weld seam does not have to be arranged on one end face. Rather, it can e.g. B. are also on a side wall if the visual requirements for the rung profile allow this.
