Description

Hohlkammerprofil  Hollow chamber profile
Die Erfindung betrifft ein Hohlkammerprofil, insbesondere Fenster- oder Tür-Hohlkammerprofil, mit mindestens einer Hohlkammer. The invention relates to a hollow chamber profile, in particular window or door hollow chamber profile, with at least one hollow chamber.
Derartige Hohlkammerprofile werden in der Regel mittels eines Extrusionsprozesses aus Kunststoffmaterial, beispielsweise PVC, hergestellt. Aufgrund der großen Abmessungen von Fenster und Türen ist es regelmäßig erforderlich, diese Profile mit einer zusätzlichen Armierung zu versehen. Üblicherweise werden hierzu Metallprofile in das Hohlkammerprofil eingeschoben. Aus der DE 20 2009 006 858 U1 ist ein Hohlprofilelement für einen Tür- oder Fensterrahmen bekannt, in die L-förmige Armierungselemente eingeschoben werden. Die Armierungselemente werden durch das Einbringen eines Dämmschaums im Hohlprofilelement festgelegt. Aus der WO 2009/098069 A1 ist ein Profil für Fenster- oder Türrahmen bekannt, welches ein Armierungselement aus Kunststoff mit Glasfaserverstärkung aufweist. Such hollow chamber profiles are usually produced by means of an extrusion process of plastic material, such as PVC. Due to the large dimensions of windows and doors, it is regularly necessary to provide these profiles with an additional reinforcement. Usually this metal profiles are inserted into the hollow chamber profile. From DE 20 2009 006 858 U1 a hollow profile element for a door or window frame is known, are inserted into the L-shaped reinforcing elements. The reinforcing elements are determined by the introduction of an insulating foam in the hollow profile element. From WO 2009/098069 A1 a profile for window or door frame is known, which has a reinforcing element made of plastic with glass fiber reinforcement.
Zur Befestigung von z.B. Beschlagelementen weisen Fenster- bzw. Tür-Hohlkammerprofile häufig Innenstege auf, in die Schrauben zur Festlegung der Beschläge ein- gedreht werden. Bei komplexer Werkzeugtechnik besteht hierbei häufig das Problem, dass die gewünschten Innensteggeometrien nicht im gewünschten Maße bereitgestellt werden können. For attachment of e.g. Fitting elements window or door hollow chamber profiles often have inner webs, in the screws for fixing the fittings are turned. In the case of complex tool technology, there is often the problem that the desired inner web geometries can not be provided to the desired extent.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Hohlkammerprofil, insbesondere Fenster- oder Tür-Hohlkammerprofil, mit mindestens einer Hohlkammer anzugeben, welches eine hohe mechanische Belastbarkeit aufweist und dabei hinsichtlich seiner Funktionalität nicht eingeschränkt ist. Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass an mindestens einer Innenseite der Hohlkammer ein die Hohlkammer mechanisch verstärkendes Verstärkungsband mit einer profilierten Kontur angeordnet, vorzugsweise befestigt, ist, die dem Verstärkungsband eine zusätzliche Funktion verleiht. Erfindungsgemäß wird also die mechanisch verstärken- de Funktion des Verstärkungsbandes mit einer weiteren Funktion dieses Bandes kombiniert, welche über eine entsprechend profilierte Bandkontur sichergestellt wird. Against this background, the invention has for its object to provide a hollow chamber profile, in particular window or door hollow chamber profile, with at least one hollow chamber, which has a high mechanical strength and is not limited in terms of its functionality. According to the invention the object is achieved in that arranged on at least one inner side of the hollow chamber, a hollow chamber mechanically reinforcing reinforcing tape with a profiled contour, preferably fastened, which gives the reinforcing tape an additional function. According to the invention, therefore, the mechanically amplifying function of the reinforcing band is combined with a further function of this band, which is ensured by means of a correspondingly profiled band contour.
Vorzugsweise ist das Verstärkungsband hierbei derart ausgebildet, dass es einen In this case, the reinforcing band is preferably designed such that it has a
Schraubkanal zur Befestigung mindestens einer Schraube am Hohlkammerprofil bildet. Diese Schraube kann beispielsweise zur Befestigung eines Beschlages am Hohlkammerprofil dienen. Gemäß einer bevorzugten Ausführungsform der Erfindung weist das Verstärkungsband eine sägezahnartige Profilierung auf. Pro Zahn werden hierdurch zwei Schnittebenen mit der Längsachse einer Schraube gebildet, so dass bereits durch die Anordnung von einem oder zwei Zähnen eine sichere Festlegung der Schraube erfolgen kann. Screw channel for mounting at least one screw on the hollow chamber profile forms. This screw can serve for example for fastening a fitting on the hollow chamber profile. According to a preferred embodiment of the invention, the reinforcing strip has a sawtooth-like profiling. For each tooth two cutting planes are formed with the longitudinal axis of a screw, so that even by the arrangement of one or two teeth can be done securely fixing the screw.
Zweckmäßigerweise wird das Verstärkungsband bei der Extrusion des Hohlkammerprofils in die Hohlkammer eingebracht. Die Profilierung des Verstärkungsbandes kann hierbei direkt im Extrusionswerkzeug erfolgen, in dem beispielsweise das unprofilierte Verstärkungsband vorgewärmt in den Extrusionskopf einläuft und dort umgeformt wird. Die Aushärtung des Verstärkungsbandes erfolgt dann zweckmäßigerweise erst in der Kühlstrecke. Alternativ kann die Profilierung des Verstärkungsbandes auch durch dem Extrusionsvorgang vorgeschaltete Einrichtungen bzw. separat vor der Extrusion erfolgen, beispielsweise durch Rollensätze. In diesem Fall kann das Verstärkungsband in bereits profilierter Form in das Extrusionswerkzeug einlaufen. Conveniently, the reinforcing strip is introduced in the extrusion of the hollow chamber profile in the hollow chamber. The profiling of the reinforcing tape can in this case be carried out directly in the extrusion tool, in which, for example, the unprofiled reinforcing tape preheated enters the extrusion head and is formed there. The curing of the reinforcing strip is then expediently only in the cooling section. Alternatively, the profiling of the reinforcing strip can also take place by means of devices preceding the extrusion process or separately before the extrusion, for example by roller sets. In this case, the reinforcing strip can enter the extrusion tool in already profiled form.
Zweckmäßigerweise weist das Verstärkungsband eine Beschichtung auf, die eine sichere Anhaftung des Verstärkungsbandes an der Hohlkammerwandung gewährleistet. So kann beispielsweise die Beschichtung aus einem Material bestehen, welches mit dem Material der Hohlkammerwandung, beispielsweise PVC, verklebt. Conveniently, the reinforcing tape has a coating which ensures a secure adhesion of the reinforcing strip to the hollow chamber wall. For example, the coating may consist of a material which adheres to the material of the hollow chamber wall, for example PVC.
Das Verstärkungsband selbst kann aus Metall oder Kunststoff bestehen, insbesondere einem Organoblech. Organobleche sind plattenförmige, thermoplastische Prepregs, die eine Faserverstärkung enthalten. Die Faserverstärkung kann beispielsweise aus Endlosfasern bestehen, welche unidirektional ausgerichtet oder aber auch als Gewebe ausgebildet sein können. Alternativ ist auch der Einsatz von einem duroplastischem Prepregs als Verstärkungsband möglich. The reinforcing tape itself may be made of metal or plastic, in particular an organic sheet. Organic sheets are plate-shaped, thermoplastic prepregs containing a fiber reinforcement. The fiber reinforcement may for example consist of continuous fibers, which are unidirectionally aligned or else designed as a fabric can. Alternatively, the use of a thermosetting prepreg as a reinforcing tape is possible.
Die Matrix des Hohlkammerprofils kann bereichsweise oder vollständig aus faserverstärk- tem Kunststoff bestehen. Als Verstärkungsfasern können Mineral- und / oder Karbon- und / oder Aramid- und / oder Basaltfasern verwendet werden. Ganz allgemein können die genannten Verstärkungsfasern auch zur mechanischen Verstärkung des erfindungsgemäßen Verstärkungsbandes eingesetzt werden, in dem sie beispielsweise in eine entsprechende Kunststoff-Matrix des Verstärkungsbandes integriert werden. The matrix of the hollow chamber profile may consist of regions or completely of fiber-reinforced plastic. As reinforcing fibers, mineral and / or carbon and / or aramid and / or basalt fibers can be used. In general, the stated reinforcing fibers can also be used for mechanical reinforcement of the reinforcing tape according to the invention, in which they are integrated, for example, in a corresponding plastic matrix of the reinforcing tape.
Die Erfindung betrifft insbesondere Hohlkammerprofile, bei denen die mit dem erfindungsgemäßen Verstärkungsband versehene Hohlkammer einen ansonsten freien Querschnitt, insbesondere einen nicht ausgeschäumten Querschnitt, aufweist. Im Rahmen der Erfindung liegt es aber auch, dass die entsprechende Hohlkammer mit Schaummaterial ausge- schäumt ist. Das Schaummaterial kann hierbei aus einem organischen Material mit niedriger Wärmeleitfähigkeit, insbesondere Polystyrol, Polyvinylchlorid, Polyethylen, Polyurethan oder Mischungen zweier oder mehr der genannten Materialien, bestehen. Alternativ ist jedoch auch die Ausschäumung mit einem anorganischen Material denkbar. Generell kann das Schaummaterial auch als Profil in das Hohlkammerprofil eingeschoben werden. In particular, the invention relates to hollow chamber profiles in which the hollow chamber provided with the reinforcing strip according to the invention has an otherwise free cross-section, in particular a non-foam-filled cross section. In the context of the invention, however, it is also the case that the corresponding hollow chamber is foamed with foam material. The foam material may in this case consist of an organic material with low thermal conductivity, in particular polystyrene, polyvinyl chloride, polyethylene, polyurethane or mixtures of two or more of the materials mentioned. Alternatively, however, the foaming with an inorganic material is conceivable. In general, the foam material can also be inserted as a profile in the hollow chamber profile.
Durch die erfindungsgemäße profilierte Gestalt des Verstärkungsbandes kann die Due to the profiled shape of the reinforcing strip according to the invention, the
Querschnittsgeometrie des Hohlkammerprofils vereinfacht werden, da nunmehr keine entsprechenden Stege zur Schraubkanalbildung mehr vorgesehen werden müssen. Hierdurch vereinfacht sich auch der ggf. vorzunehmende Ausschäumprozess. Cross-sectional geometry of the hollow chamber profile can be simplified because now no corresponding webs have to be provided for Schraubkanalbildung more. This also simplifies the possibly necessary foaming process.

Zur Herstellung des Hohl- kammerprofils 1 wird Polyvinylchlorid verwendet, welches bei Bedarf bereichsweise oder vollständig aus faserverstärkt ausgebildet ist. Wie der Fig. 1 zu entnehmen ist, ist an bei einander gegenüberliegenden Innenseiten der Hohlkammer 2 jeweils ein die Hohlkammer 2 mechanisch verstärkendes Verstärkungsband 3 mit einer profilierten Kontur angeordnet. Die profilierte Kontur verleiht den Verstärkungsbändern 3 eine zusätzliche Funktion. Vorliegend sind die Verstärkungsbänder 3 derart ausgebildet, dass sie jeweils einen Schraubkanal zur Befestigung einer (nicht dargestellten) Schraube am Hohlkammerprofil 1 (angedeutet durch strichpunktierte Linien x) bilden. Die Verstärkungsbänder 3 weisen hierzu jeweils eine sägezahnartige Profilierung auf. Pro Zahn 4 werden hierdurch zwei Schnittebenen mit der Schraubachse x gebildet. Entsprechend liegen bereits durch das Vorsehen von zwei Zähnen 4 vier Schnittebenen mit der Schraubachse x vor, so dass beim Eindrehen der Schraube eine sichere Verankerung derselben am Hohlkammerprofil 1 erfolgt. Die Zahnspitzen sind unter Bildung von Zwischenstücken 5 abgeflacht ausgebildet. Ferner sind die Zähne 4 jeweils durch einen Zwischenabschnitt 6 voneinander beabstandet. Fig. 1 shows a hollow chamber profile 1, which serves for the production of window or door frame. The hollow chamber profile 1 has a plurality of hollow chambers 2, 2 'and is produced by means of an extrusion process of plastic. For the production of the hollow Chamber profile 1 polyvinyl chloride is used, which is designed as needed or partially made of fiber reinforced. As can be seen in FIG. 1, a reinforcing band 3 mechanically reinforcing the hollow chamber 2 is arranged with a profiled contour on mutually opposite inner sides of the hollow chamber 2. The profiled contour gives the reinforcing bands 3 an additional function. In the present case, the reinforcing bands 3 are designed such that they each form a screw channel for fastening a screw (not shown) on the hollow chamber profile 1 (indicated by dot-dash lines x). For this purpose, the reinforcing bands 3 each have a sawtooth-like profiling. For each tooth 4, two cutting planes are thus formed with the screw axis x. Correspondingly, four sectional planes with the screw axis x are already present through the provision of two teeth 4, so that a secure anchoring thereof to the hollow chamber profile 1 takes place when the screw is screwed in. The tooth tips are flattened to form intermediate pieces 5. Further, the teeth 4 are spaced from each other by an intermediate portion 6.
Die Verstärkungsbänder 3 weisen eine (nicht dargestellte) Beschichtung auf, die eine sichere Anhaftung der Bänder 3 an der Hohlkammerwandung gewährleistet. Die Beschichtung besteht aus einem mit PVC verklebenden Material. Die Verstärkungsbänder 3 wurden während des Extrusionsprozesses des Hohlkammerprofils 1 in die Hohlkammer 2 einge- bracht, indem die entsprechenden Bänder 3 in das Extrusionswerkzeug einlaufen. Die mit den Verstärkungsbändern 3 versehene Hohlkammer in Fig. 1 weist einen ansonsten freien Querschnitt ohne Ausschäumung auf. The reinforcing bands 3 have a coating (not shown), which ensures a secure adhesion of the bands 3 to the hollow chamber wall. The coating consists of a PVC-bonded material. The reinforcing bands 3 were introduced into the hollow chamber 2 during the extrusion process of the hollow-chamber profile 1 by running the corresponding bands 3 into the extrusion tool. The provided with the reinforcing bands 3 hollow chamber in Fig. 1 has an otherwise free cross section without foaming.
Beim Ausführungsbeispiel gemäß Fig. 2 ist hingegen die entsprechende Hohlkammer 2 zusätzlich mit Schaummaterial 7 ausgeschäumt. Dieses Schaummaterial 7 besteht aus einem organischen Material mit niedriger Wärmeleitfähigkeit, im Ausführungsbeispiel Polyurethan. Die von den Zähnen 4 gemeinsam mit der Hohlkammerwandung gebildeten Hohlräume 8 sind frei von Schaummaterial 7. Darüber hinaus ist in Fig. 2 erkennbar, dass dort eine weitere Kammer 2' des Hohlkammerprofils 1 mit einer Ausschäumung versehen worden ist. Diese Hohlkammer 2' ist ebenfalls mit einem Verstärkungsband 3' versehen, welches jedoch keine Profilierung aufweist. Beim Ausschäum prozess dienen die Verstärkungsbänder 3, 3' nicht nur zur Armierung des hergestellten Profils 1 , sondern verhindern auch eine Deformation des Hohlkammerprofiles 1 während des Ausschäumprozesses, bei dem aufgrund der Expansion des Schaummaterials 7 sehr große Kräfte entstehen können. Im Ausführungsbeispiel gemäß Fig. 3 weist die Hohlkammerwandung eine Unterbrechung 9 zur Aufnahme des Verstärkungsbandes 3 auf. Wie dem vergrößerten Ausschnitt in Fig. 3 zu entnehmen ist, hintergreift das Verstärkungsband 3 die Unterbrechung 9. Das Verstärkungsband 3 ist hier symmetrisch ausgebildet und weist entsprechend zwei sägezahnartige Profilierungen auf. Alternativ kann jedoch auch ein asymmetrisches Verstärkungsband 3 - wie z.B. in Fig. 3 rechts dargestellt - in der Unterbrechung 9 aufgenommen sein. In the embodiment of FIG. 2, however, the corresponding hollow chamber 2 is additionally foamed with foam material 7. This foam material 7 consists of an organic material with low thermal conductivity, in the embodiment polyurethane. The cavities 8 formed by the teeth 4 together with the hollow chamber wall are free of foam material 7. In addition, it can be seen in Fig. 2 that there is a further chamber 2 'of the hollow chamber profile 1 has been provided with a foaming. This hollow chamber 2 'is also provided with a reinforcing strip 3', which, however, has no profiling. During the foaming process, the reinforcing bands 3, 3 'not only serve to reinforce the manufactured profile 1, but also prevent deformation of the hollow chamber profile 1 during the foaming process, in which due to the expansion of the foam material 7 very large forces can arise. In the embodiment according to FIG. 3, the hollow chamber wall has an interruption 9 for receiving the reinforcing strip 3. As can be seen from the enlarged detail in FIG. 3, the reinforcing strip 3 engages behind the interruption 9. The reinforcing strip 3 is designed symmetrically here and accordingly has two sawtooth-like profilings. Alternatively, however, an asymmetric reinforcing band 3 -as shown for example in FIG. 3 on the right-can also be accommodated in the interruption 9.
