Gelochte Hohlprofile sind bereits bekannt, bei denen die Lochung mittels eines Dorns erfolgt. Diese Art der Herstellung von Lochungen ist jedoch dann nicht mehr möglich, wenn die Profile zu lang sind ( mehrere Meter lang ) oder in den Querschnittsabmessungen zu gering sind. Es ist auch bekannt, Löcher zu bohren, doch lassen sich damit nur runde Lochungen herstellen.Perforated hollow profiles are already known in which the perforation by means of of a mandrel. However, this type of production of perforations is then not more possible if the profiles are too long (several meters long) or in the cross-sectional dimensions are too low. It is also known to drill holes, but this is the only way to do it Make round holes.
Aufgabe der Erfindung ist eine solche Ausbildung eines gelochten Hohlprofils, daß bei beliebiger Länge des Profils beliebige Lochungen erzielbar sind.The object of the invention is such a design of a perforated hollow profile, that with any length of the profile any perforations can be achieved.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß das Hohlprofil aus zwei offenen Teilprofilen besteht, die formschlüssig ineinanderpassen.This object is achieved according to the invention in that the hollow profile consists of two open partial profiles that fit together form-fittingly.
Die offenen Teilprofile können mit einer Lochmatrize in jeder gewünschten Weise gelocht werden. Dies ist bei beliebiger Länge möglich. Sodann kann man in einfacher Weise die Teilprofile zusammenfügen. Die Teilprofile können allein durch federnden Formschluß zusammengehalten werden; es ist auch zusätzlich, die Verwendung von Bindemitteln möglich.The open partial profiles can be made in any desired with a perforated matrix Way to be punched. This is possible with any length. Then you can use simply join the partial profiles together. The partial profiles can go through alone resilient form fit are held together; it is also additionally, the use of binders possible.
Die-Teilprofile können jeweils einen U-förmigen Querschnitt aufweisen, so daß sich jeweils in gegenüberliegenden Seitenflächen des Hohlprofils Stoßkanten ergeben. Diese Stoßkanten legt man vorzugsweise auf die Schmalseiten. In diesem Fall ist jeweils nur eine Lochung der Mittelgurte eines jeden Teilprofil möglich. Wenn eine Lochung in allen vier Seitenwandungen des Hohlprofils gewunscht ist, bildet man ein Teilprofil als U-Schiene aus, das jeweils andere Teilprofil als Mittelgurt mit daran sitzenden Hakenstegen.The partial profiles can each have a U-shaped cross-section, so that abutting edges are in each case in opposite side surfaces of the hollow profile result. These abutting edges are preferably placed on the narrow sides. In this In this case, only one perforation of the central belts of each partial profile is possible. If a perforation is desired in all four side walls of the hollow profile, forms one part profile is selected as a U-rail, the other part profile as a central flange with attached hook bars.
In weiterer Ausbildung betrifft die Erfindung ein Verfahren zur Herstellung eines gelochten Hohlprofils, wonach zwei einander zu dem gewünschten Hohlprofil ergänzende Teilprofile in ihren Wandungen gelocht werden und wonach die Teilprofile längs der Verbindungsnähte zusammengctü.gt werden Die Erfindung ermöglicht die Herstellung gelochter Hohlprofile in beliebigen Längen. Derartige Hohlprofile können als Montageprofile, als Bauprofile, für Möbelteile, Regale oder dgl.In a further development, the invention relates to a method for production a perforated hollow profile, after which two each other to form the desired hollow profile additional partial profiles are perforated in their walls and after which the partial profiles are joined together along the connecting seams. The invention enables production perforated hollow profiles in any length. Such hollow profiles can be used as assembly profiles, as construction profiles, for furniture parts, shelves or the like.

Die Teilprofile 2 und 3 haben einen U-förmigen Querschnitt und endigen jeweils in Seitenstege-4 bzw. 6. Die Seitenstege 4 des Teilprofils 2 weisen im Endbereich eine Ansatzkante 5 auf. An dem gegenüberliegenden Teilprofil 3 sitzen an den Seitenstegen 6 Hakenstege die paarig zu der jeweiligen Ansatzkante 5 ausgebildet sind.Fig. 2 shows the profile cross-section, according to which the hollow profile 1 consists of two Partial profiles 2 and 3 exist. The partial profiles 2 and 3 have a U-shaped cross section and each end in side bars 4 and 6, respectively. The side bars 4 of the partial profile 2 have a shoulder 5 in the end area. On the opposite partial profile 3 sit on the side bars 6 hook bars in pairs to the respective approach edge 5 are formed.
Die Länge der Hakenstege 7 ist so bemessen, daß gegenüber der Breitseite des Teilprofils 2 ein Spalt 8 freibleibt. Fig. 1 zeigt die Ansicht des Hohlprofils, wo innerhalb des Teilprofils 3 Lochungen 9 mit beliebigem Umriß ausgeschnitten sind. Die Lochungen 9 können einerseits nur in einem Teilprofil oder andererseits in beiden Teilprofilen angeordnet sein, insbesondere kann man in beiden Teilprofilen miteinander fluchtende Lochungen vorsehen.The length of the hook webs 7 is dimensioned so that opposite the broad side of the partial profile 2 a gap 8 remains free. Fig. 1 shows the view of the hollow profile, where within the partial profile 3 holes 9 are cut out with any contour. The perforations 9 can on the one hand only in a partial profile or on the other hand in both Partial profiles be arranged, in particular one can in both partial profiles with each other Provide aligned holes.
Fig. 2 zeigt einen Profilquerschnitt, wo beide Teilprofile 2 und 3 im wesentlichen U-förmig gestaltet sind, so daß sich etwa in der Mitte der Seitenwandungen eine Stoßkante ergibt.Fig. 2 shows a profile cross-section where both partial profiles 2 and 3 are designed essentially U-shaped, so that there are approximately in the middle of the side walls results in an abutting edge.
Diese Profilform ist für ein Hohlprofil geeignet, wo lediglich in den Breitseiten des Profils Lochungen erforderlich sind.This profile shape is suitable for a hollow profile where only in perforations are required on the broad sides of the profile.
Wenn in allen vier Seitenwandungen des Hohlprofils Lochungen PeMlnscbtt werden, wählt man eine Profilform nach Fig. 3.If perforations are made in all four side walls of the hollow profile a profile shape according to FIG. 3 is selected.
Das Teilprofil 2' weist Seitenstege 4' auf, die über die gesamte Breite der betreffenden Seitenwandungen reichen und in Ansatzkanten 5 endigen. Das zugehörige Teilprofil 3 besteht ~ im wesentlichen aus einem ebenen Abschlußgurt für eine Breit-), seite, an welchem Hakenstege 7' sitzen, die hinter die Ansatzkanten 5 der Seitenstege 4' greifen. Fig. 3 zeigt die Teilprofile in voneinander getrenntem Zustand. Bei dem Teilprofil 2' ist eine Lochung in allen drei Seitenwandungen möglich.The partial profile 2 'has side webs 4' over the entire width the side walls in question and end in 5 approach edges. The associated Partial profile 3 consists essentially of a flat end belt for a wide), side on which hook webs 7 'sit behind the edge 5 of the side webs 4 'grab. Fig. 3 shows the partial profiles in a separated state. at the partial profile 2 'a perforation in all three side walls is possible.
Ebenso kann der Gurt des Teilprofils 3' gelocht werden.- Das Zusanunensetzen der Teilprofile erfolgt in der oben beschriebenen Weise, so daß man ein Hohlprofil erhält, das Lochungen in-allen vier Seitenwandungen aufweist.The belt of the partial profile 3 'can also be perforated the partial profile is carried out in the manner described above, so that a hollow profile receives, which has holes in all four side walls.
Ein solches Hohlprofil eignet sich besonders als Kanal zur Verlegung von Leitungen. Es ist eine Unterputz- oder Unterflurverlegung des Teilprofils 2' möglich, worauf nach Einfügen der Leitungen das Teilprofil 3' deckelartig aufgesetzt wird.
