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 aus Aluminium, für Isolierverglasungen sowie ein Verfahren zur Herstellung des Sprossenhohlprofils.The invention relates to a hollow hollow profile made of metal, in particular made of aluminum, for double glazing and a process for the production of the hollow rung profile.

Sprossen in Isolierverglasungen werden zwischen zwei Glasscheiben von z. B. Fenstern angeordnet. Die Sprossen bestehen aus Hohlprofil stangen, die z. B. mittels Kreuzverbindungsstücken zusammengesteckt sind und mit Verbindungsstopfen mit dem Abstandhalterrahmen der Isolierverglasung in Verbindung stehen. Die Sprossen haben entweder die Metall farbe 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 glass from Z. B. windows arranged. The rungs consist of Hollow profile rods, the z. B. by means of cross connectors are plugged together and with connecting plugs with the spacer frame of the double glazing. The rungs either have the metal color or they are with Color coated, the color of the sprouts mostly the color the window frame is adjusted.

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 extruded a hollow profile rod as a closed profile. At this method of manufacture is a relatively thick wall predefined for the hollow section bar because of thin wall thicknesses are not extrudable at a reasonable cost. For one such rung is therefore relatively much material used. A Another disadvantage is that an outer coating of the hollow profile rod is complex because the coating only after the Profiling can be done.

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 is made from a metal strip with a hollow profile rod a butt joint formed, which is then closed by welding becomes.

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 by this method, the Weld seam visible on the surface, which is visually unattractive. A coating can make the weld invisible be made, but the subsequent coating is also complex as in the case of extruded hollow hollow profiles. In addition, the ink consumption is high because the coating Cover the weld seam so that the weld seam is invisible becomes. It is not possible to apply paint before welding because burn the paint around the weld when welding and the hollow profile would become unsightly.

Ferner ist aus der DE 34 00 891 A1 ein rohrfömiger Abstandhalter für Isolierglas bekannt, der aus einem Flachmaterialstreifen hergestellt wird, indem dessen Ränder durch Rollverformen zusammengebogen und miteinander verschweißt werden. Diese Abstandhalter dienen dazu, zwei Glasscheiben auf einem vorbestimmten Abstand zu halten. Sie werden deshalb am Rand der Glasscheiben im Bereich des Fensterrahmens zwischen den Glasscheiben angeordnet und mit diesen verklebt. Die Abstandhalter sind in der Regel mit einem Trocknungsmittel gefüllt. Dieser Abstandhalter kann mit einer von der Rohraußenfläche entfernt und dem Rohrinneren benachbart angeordneten Verschweißung versehen sein. Hierzu werden die einen Längsschlitz bildenden Ränder des Flachmaterialstreifens vor ihrem Verschweißen unter Wahrung von Abstand zwischen ihren Außenkanten aneinander gelegt und nur in dem dem Rohrinneren benachbarten Berührungsbereich mit einem der Außenkanten unberührt lassenden Schweißstreifen außen verschweißt, wonach das Rohr unter Beseitigung des Außenkantenabstandes in seine endgültige Profilform gerollt wird. Der Abstand der Außenkanten voneinander gewährleistet beim Schweißen, daß der entsprechend scharf gebündelte Schweißstrahl keinen Einfluß auf die Außenkanten nehmen soll, was insbesondere bei der Verwendung von mit einem einer Nutzschicht versehenen Flachmaterialstreifen zur Herstellung des Abstandhalters von Vorteil ist. Dieses Verfahren ist jedoch sehr aufwendig, da die Ränder mit dem dem Rohrinneren benachbarten Berührungsbereich exakt aneinander gelegt werden müssen, wobei die an die Ränder angrenzenden Bereiche des Flachmaterialstreifens so weggebogen werden, daß die Außenkanten der Ränder voneinander beabstandet sind.Furthermore, a tubular spacer is known from DE 34 00 891 A1 known for insulating glass, which consists of a flat material strip is produced by rolling the edges together by roll forming and welded together. These spacers serve two panes of glass on a predetermined Keep your distance. You will therefore be on the edge of the glass panes arranged in the area of the window frame between the glass panes and glued to them. The spacers are usually filled with a desiccant. This spacer can with one removed from the outside of the pipe and the inside of the pipe adjacent welding may be provided. For this the edges of the flat material strip forming a longitudinal slot before welding them while maintaining a distance placed between their outer edges and only in that Inside of the tube adjacent contact area with one of the outer edges welding strips left untouched welded on the outside, after which the pipe in eliminating the outer edge distance its final profile shape is rolled. The distance between the outer edges guarantees each other when welding that the corresponding sharply focused welding beam does not affect the Should take outside edges, which is particularly important when using with a flat material strip provided with a wear layer for Manufacturing the spacer is advantageous. This method is however very complex, since the edges with the inside of the pipe adjacent contact area are placed exactly next to each other must, the areas of the flat material strip adjoining the edges be bent away so that the outer edges of the Edges are spaced apart.

Aus der DE 29 18 581 A1 geht auch ein Abstandhalter für Mehrscheibenisolierverglasungen hervor. Dieser Abstandhalter weist ein Metallprofil mit einer Längsrille auf. Das sich in einem Fensterrahmen zwischen zwei Glasscheiben befindliche Metallprofil ist mit Trockenmittel ausgefüllt. Dieser Abstandhalter ist aus einem Metallstreifen hergestellt, dessen Ränder zur Ausbildung der Längsrille nach innen gefaltet sind, so daß Randstege des Metallstreifens die V-förmige Rille begrenzen. Diese Randstege berühren sich im Bereich des Rillenbodens elastisch federnd, so daß sie ein Austreten des Trockenmittels sicher verhindern und zugleich den notwendigen Gasaustausch ermöglichen.DE 29 18 581 A1 also describes a spacer for multi-pane insulating glazing forth. This spacer has one Metal profile with a longitudinal groove. That all in one Window frame between two glass panes located metal profile is filled with desiccant. This spacer is off made of a metal strip, the edges of which form the Longitudinal groove are folded inwards so that edge webs of the Metal strip limit the V-shaped groove. These bridges touch resiliently in the area of the groove bottom, so that they safely prevent leakage of the desiccant and at the same time enable the necessary gas exchange.

Aus der GB 281 773 A ist ein weiterer Abstandhalter bekannt, der aus dünnem Stahlblech hergestellt wird. Ferner ist in der DE 32 03 808 A1 ein weiterer im Querschnitt rechteckiger Abstandhalter beschrieben, der aus einem dünnen Blechstreifen hergestellt ist, wobei die Ränder des Blechstreifens sich überdeckend miteinander verklebt sind.Another spacer is known from GB 281 773 A. is made of thin sheet steel. Furthermore, DE 32 03 808 A1 another spacer with a rectangular cross section described, which is made of a thin strip of sheet metal, the edges of the sheet metal strip overlapping one another are glued.

Aus der DE 35 13 382 A1 geht ein Tragprofil für Montageeinrichtung, Stützkonstruktionen und Transportbänder hervor, das einen im wesentlichen rechteckigen oder quadratischen Profilquerschnitt aufweist, wobei hinterschnittene Längsnuten an gegenüberliegenden Profillängsseiten zur Aufnahme von Verbindungsmitteln, wie Befestigungsschrauben, Halteteilen oder ähnlichen Verbindungselementen, eingebracht sind. DE 35 13 382 A1 describes a support profile for the assembly device, Support structures and conveyor belts emerge, the one in essential rectangular or square profile cross section has, with undercut longitudinal grooves on opposite Longitudinal profile sides for receiving fasteners, such as Fastening screws, holding parts or similar Fasteners are introduced.

Am Boden einer der Längsnuten ist eine Längsschweißnaht angeordnet, mit der das Tragprofil aus einem mehrfach abgekanteten Blechstreifen zusammengehalten wird. Dieses Tragprofil dient zur mechanischen Stützung der Montageeinrichtungen, Stützkonstruktionen und Transportbänder, so daß es im Vergleich zu einem Sprossenhohlprofil für Isolierverglasungen wesentlich stärker und größer dimensioniert sein muß. Die Längsnuten, die zur Aufnahme von Verbindungsmitteln dienen, sind dementsprechend breit ausgeführt, damit die Verbindungsmittel in die Nut eingeführt werden können.A longitudinal weld is arranged on the bottom of one of the longitudinal grooves, with which the support profile from a multiple folded Metal strip is held together. This support profile is used for mechanical support of the assembly facilities, support structures and conveyor belts so that it is compared to one Hollow rung profile for insulating glazing much stronger and must be larger. The longitudinal grooves that are used for receiving of lanyards are accordingly wide executed so that the connecting means are inserted into the groove can be.

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, in a simple manner, metal-colored as well colored coated hollow hollow profiles with weld seam create where the weld seam is not distracting and the are relatively resistant to bending and torsion despite the small wall thickness. In addition, a simple and economical process for Manufacture of this hollow hollow profile can 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 7 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Unteransprüchen angegeben.This task is carried out with regard to the hollow hollow profile Features of claim 1 and regarding the manufacture of this Rung hollow profile solved by the features of claim 7. Advantageous developments of the invention are in the dependent Subclaims specified.

Beispielsweise können die Profileinziehungen im Querschnitt U- oder V-förmige Rillen sein, wobei die Schweißnaht optisch ebenfalls nicht störend sich im Bereich des Bodens einer der Rillen befindet.For example, the profile indentations in cross section U- or V-shaped grooves, the weld seam also optically there is no disturbance in the area of the bottom of one of the grooves.

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 not only relates to sprouts for Rung windows with double glazing, but also 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 double glazing points in general a window frame 2, at least two spaced apart, in the window frame 2 glass panes 3 and one the glass panes 3 keep a distance, filled with desiccant Spacer frame 4 on. In the space between the glass panes 3 rungs 5 are arranged. The rungs 5 exist made of metal hollow profile rods with a longitudinal weld 12a, which are put together to form an intersection. At the crossing points are the rungs 5 in a manner known per se Cross connectors assembled (not shown). Connection plugs take over in a manner known per se Storage of the rungs 5 on the spacer frame 4.

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 exhibit. A common profile is shown that runs parallel to the glass panels 3 arranged side walls 6 and transverse to the Has side walls 6 extending end walls 7. 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 in deren Längsmitte eine längsverlaufende Profileinziehung 8, 8b bzw. rillenförmige Einbuchtungen 9, 9a einprofiliert ist.It is essential that in both end walls 7th in the middle of the longitudinal profile drawing 8, 8b or groove-shaped indentations 9, 9a is profiled.

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 mirror images arranged to each other. The depth of each groove is 9, 9a e.g. 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 possible be small, but in any case so small that the groove bottom remains invisible from the outside. The side walls are preferably located 8a of the grooves 9, 9a together.

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 aufeinander zu 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 lla in gleicher Weise gerillt wird und die Rillung 9a enthält.The rungs 5 are each in the required length of Hollow section rods 11 cut to length. The hollow profile rods 11 are from a relatively thin metal band, e.g. B. molded from aluminum, the longitudinal edges 12 of the metal strip towards each other are bent 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 one Profiling produces the grooves 9, 9a in such a way that the weld 12a is displaced into the interior 5a of the profile and becomes invisible. So that the rung 5 looks uniform, is provided according to an expedient embodiment of the invention, that the groove 9 with the weld 12 opposite Area of the tube lla is grooved in the same way and the groove 9a contains.

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 preferably consists of Aluminum. The wall thickness of the rung is in particular approximately 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 process for producing a hollow profile rod 11 results from Fig. 3. Starting material is a relatively wide metal strip 13, the 14 by a broadband coil is subtracted. The metal strip 13 consists, for. B. made of aluminum and has a relatively thin layer of paint on the outside 13a 6c.

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 initially divided into several during the removal Strips 15 cut longitudinally, preferably from each at the same time hollow profile rods 11 z. B. by roll deformation and / or shaped. The strips 15 can also rolled up and processed later. The hollow profiles 11 formed from strips 15 may be the same or have different cross-sectional shapes. As well the strips 15 can be the same width or different widths be.

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 lla 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 several strips 15 through longitudinal cuts 16 are made at a processing station A, which passes through the metal strip 13 when pulled off. In The take-off direction is behind processing station A a processing station B with shaping tools (not shown), in which the strip 15 to a z. B. in cross section circular tube lla with abutting longitudinal edges 12 is formed. The color layer 6c is located on the Outer jacket surface of the pipe. At one of the processing stations B downstream processing station C with a welding device the longitudinal edges 12 are welded to the weld 12a, preferably laser welded. Behind the processing station C there is a processing station D with molds (not shown) with which the profile indentations 8, 8b be molded and at the same time or subsequently also Profiling of the side walls 6, 6a and end walls 7 can be shaped.

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. Through the profile retraction according to the invention in the area of Weld seam are the weld seam itself as well as by the Heat from welding affected color areas in the groove 9 hidden so that they remain invisible from the outside. By This unusual measure is achieved from a coated Metal band shaped and welded hollow profiles as Rungs can be used without the weld and optically disturb the partially burned color areas. But also If uncoated metal strips are used, sprouts can appear be formed, the weld seam is hidden and not optically is disturbing.

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 on suitable trade lengths cut to length and are an intermediate product to the manufacturer of double glazing. 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, eine Profileinziehung zur Unsichtbarmachung einer Schweißnaht vorzusehen und schlägt aus optischen Gründen vor, zumindest eine weitere Profileinziehung spiegelbildlich zur Profileinziehung mit der Schweißnaht anzuordnen.The invention thus teaches a profile retraction Providing invisibility of a weld seam and knocks out optical reasons, at least one more profile retraction to be arranged in mirror image to the profile retraction with the weld seam.
