Composite masonrywork profile, comprising a core which consists of wood or another type of nailable material and is enclosed in an angle profile which consists of metal and leaves the core free on two adjacent sides in order to nail struts or the like thereon. The angle profile comprises two legs which extend transversely with respect to one another and, with the adjoining parts, form the outer walls of an internally formed rectangular tube profile and of which parts extending past the rectangular tube profile are designed as flat tubular profiles, the nailable core bearing against the walls, located within the angle profile, of the rectangular tube profile and of the flat tube profiles. <IMAGE>

Description

Die Erfindung betrifft ein zusammengesetztes Mauerprofil, insbesondere ein Mauerprofil, bei dem ein Kern aus Holz oder anderem nagelbarem Material in ein Metallprofil gefaßt ist, das mindestens örtlich den Kern freigibt, um daran Streben zum Vertikalstellen des Metallprofils festzunageln, wobei das Metallprofil als ein Winkelprofil ausgebildet ist, das den Kern an zwei benachbarten Seiten im wesentlichen freiläßt.The invention relates to a composite wall profile, in particular a wall profile, in which a core made of wood or other nailable material is contained in a metal profile, which at least locally releases the core to pin struts for vertical positioning of the metal profile, the metal profile being designed as an angle profile that essentially leaves the core free on two adjacent sides.

Ein derartiges Metallprofil ist aus der niederländischen Patentanmeldung 9100971 bekannt. Obgleich das bekannte Mauerprofil erhebliche Vorteile gegenüber den herkömmlichen Mauerprofilen aus Holz aufweist, hat es sich in der Praxis herausgestellt, daß weitergehende Verbesserungen möglich sind. So kann beim bekannten Mauerprofil trotz des Winkelprofils aus Metall unter dem Einfluß des Arbeitens der Holzteile des Profils noch eine gewisse Neigung zum Sichverwerfen bestehen.Such a metal profile is known from Dutch patent application 9100971. Although the known wall profile has considerable advantages over the conventional wall profiles made of wood, it has been found in practice that further improvements are possible. Thus, in the known wall profile, despite the angular profile made of metal, under the influence of the working of the wooden parts of the profile there can still be a certain tendency to warp.

Die Erfindung bezweckt, ein Mauerprofil mit einer weiter verminderten Neigung zum Sichverwerfen zur Verfügung zu stellen. Mehr im allgemeinen bezweckt die Erfindung, ein robustes und dauerhaftes Mauerprofil zu schaffen, das steifer als das bekannte Mauerprofil ist und verhältnismäßig wenig Holz enthält.The invention aims to provide a wall profile with a further reduced tendency to warp. More generally, the invention aims to provide a sturdy and durable wall profile that is stiffer than the known wall profile and contains relatively little wood.

Dazu wird gemäß der Erfindung ein Mauerprofil der oben beschriebenen Art dadurch gekennzeichnet, daß das Winkelprofil zwei sich quer zueinander erstreckende Schenkel umfaßt, die mit den aneinander anschließenden Teilen die Außenwände eines innen gebildeten rechteckigen Rohrprofils bilden und deren sich am rechteckigen Rohrprofil vorbei erstreckende Teile als flache rohrförmige Profile ausgebildet sind, wobei der nagelbare Kern an den innerhalb des Winkelprofils liegenden Wänden des rechteckigen Rohrprofils und der flachen Rohrprofile anliegt.For this purpose, according to the invention, a wall profile of the type described above is characterized in that the angle profile comprises two legs which extend transversely to one another and which, with the adjoining parts, form the outer walls of an internally formed rectangular tube profile and whose parts which extend past the rectangular tube profile as flat tubular profiles are formed, the nailable core abutting the walls of the rectangular tubular profile and the flat tubular profiles lying within the angular profile.

Im folgenden wird die Erfindung unter Hinweis auf die beigefügte Zeichnung eines Ausführungsbeispiels näher beschrieben werden. Es zeigen:

  • Figur 1 schematisch und perspektivisch ein Beispiel eines Mauerprofils gemäß der Erfindung;
  • Figur 2 schematisch einen Schnitt über die Linie II-II in Figur 1; und
  • Figur 3 einen ähnlichen Schnitt wie Figur 2 einer Variante des Mauerprofils nach Figur 1.
The invention will be described in more detail below with reference to the attached drawing of an exemplary embodiment. Show it:
  • Figure 1 shows schematically and in perspective an example of a wall profile according to the invention;
  • Figure 2 shows schematically a section along the line II-II in Figure 1; and
  • 3 shows a section similar to FIG. 2 of a variant of the wall profile according to FIG. 1.

Figur 1 zeigt perspektivisch ein Beispiel eines Mauerprofils gemäß der Erfindung. Das gezeigte Mauerprofil ist im wesentlichen aus einem extrudierten Winkelprofil 1 aus Metall, oft Aluminium, und einem Holzkern 2 zusammengesetzt. In der dargestellten Ausführungsform ist der Kern aus zwei Holzlatten 3 und 4 zusammengesetzt, die, wie mit Schraffierungen angegeben, vorzugsweise mit der Holzfaser entgegengesetzt angeordnet sind, um die Gefahr des Sichverwerfens auf ein Mindestmaß zu beschränken. Die Latten 3 und 4 sind miteinander verbunden, z.B. durch Nieten 5, durch Schrauben oder durch Nageln oder auf eine andere geeignete Weise. Über die Länge des Mauerprofils gesehen, ist in diesem Beispiel der Holzkern aus einem Mittelabschnitt 6, der sich über den größten Teil der Länge des Winkelprofils 1 erstreckt, und zwei Endabschnitten 7, die im gezeigten Ausführungsbeispiel an beiden Seiten aus dem Profil 1 herausragen, zusammengesetzt. Falls gewünscht, kann der Mittelabschnitt aus einer Anzahl aufeinander angeordneter Teile gebildet sein. Der Mittelabschnitt kann jedoch auch ein Ganzes mit einem oder beiden Endabschnitten bilden. Auch ist es nicht strikt notwendig, daß der Holzkern sich bis an den beiden Enden des Winkelprofils aus Metall vorbei erstreckt.Figure 1 shows in perspective an example of a wall profile according to the invention. The wall profile shown is essentially composed of an extruded angle profile 1 made of metal, often aluminum, and a wooden core 2. In the embodiment shown, the core is composed of two wooden slats 3 and 4, which, as indicated by hatching, are preferably arranged opposite to the wood fiber in order to minimize the risk of warping. Slats 3 and 4 are joined together, e.g. by rivets 5, by screws or by nailing or in some other suitable way. Seen over the length of the wall profile, in this example the wood core is composed of a central section 6, which extends over most of the length of the angle profile 1, and two end sections 7, which protrude from the profile 1 on both sides in the exemplary embodiment shown . If desired, the central section can be formed from a number of parts arranged one on top of the other. However, the middle section can also form a whole with one or both end sections. It is also not strictly necessary for the wood core to extend past the two ends of the metal angle section.

Das Winkelprofil 1 umfaßt zwei als flaches Rohrprofil ausgebildete Schenkel 8 und 9, die an ein inneres Rohrprofil 10 anschließen. Wie deutlich aus Figur 2 hervorgeht, schließt das Innenrohr 10 unter Bildung von Anliegeflächen 11,12 für die Latten 3 und 4 an jeden der Schenkel 8 und 9 an.The angle profile 1 comprises two legs 8 and 9 designed as a flat tube profile, which connect to an inner tube profile 10. As is clear from FIG. 2, the inner tube 10 connects to each of the legs 8 and 9, forming contact surfaces 11, 12 for the slats 3 and 4.

Das Metallprofil 1 hat im gezeigten Beispiel zwei Schenkel 13,14, die einen Winkel von 90° miteinander einschließen und deren aneinander anschließende Teile zugleich die Außenwände des inneren, in diesem Beispiel viereckigen, jedoch im allgemeinen rechteckigen Rohrprofils 10 bilden. Das Rohrprofil wird durch die Wände 11,12 ergänzt, die Anliegeflächen für die Latten 3 und 4 bilden.In the example shown, the metal profile 1 has two legs 13, 14, which enclose an angle of 90 ° with one another and whose adjoining parts at the same time the outer walls of the inner, in this example square, however, generally form rectangular tubular section 10. The tube profile is supplemented by the walls 11, 12, which form contact surfaces for the slats 3 and 4.

Die sich am Rohrprofil vorbei erstreckenden Teile der Schenkel 13,14 bilden zugleich Außenwände der flachen rohrförmigen Profile 8 und 9, die ebenfalls vorzugsweise einen rechteckigen Querschnitt aufweisen.The parts of the legs 13, 14 extending past the tubular profile also form outer walls of the flat tubular profiles 8 and 9, which likewise preferably have a rectangular cross section.

Die Latte 4 paßt genau in den durch die Innenwand 15 des rohrförmigen Schenkels 8 und die Anliegefläche 11 bestimmten Raum. Dabei liegt die eine Außenfläche der Latte 4 in einer Ebene mit der Stirnfläche 16 des rohrförmigen Schenkels 8 und die andere Außenfläche in einer Ebene mit der Stirnfläche 17 des anderen rohrförmigen Schenkels 9.The slat 4 fits exactly into the space defined by the inner wall 15 of the tubular leg 8 and the contact surface 11. One outer surface of the slat 4 lies in one plane with the end surface 16 of the tubular leg 8 and the other outer surface lies in one plane with the end surface 17 of the other tubular leg 9.

Die Latte 3 ist im Schnitt kleiner als die Latte 4 und paßt genau in den Raum, der durch die Innenfläche der Latte 4, die Anliegefläche 12 und die Innenwand 18 des rohrförmigen Schenkels 9 eingeschlossen wird.The crossbar 3 is smaller than the crossbar 4 and fits exactly into the space enclosed by the inner surface of the crossbar 4, the contact surface 12 and the inner wall 18 of the tubular leg 9.

Auf die beschriebene Weise kann ein im Schnitt rechteckiges, in diesem Beispiel viereckiges, zusammengesetztes Profil erhalten werden, das durch die verwendeten integrierten Rohrprofile 8, 9 und 10 sehr steif ist und relativ wenig Holz enthält. Die Gefahr des Sichverwerfens ist daher stark vermindert.In the manner described, a rectangular, in this example quadrangular, composite profile can be obtained, which is very stiff due to the integrated tubular profiles 8, 9 and 10 and contains relatively little wood. The risk of warping is therefore greatly reduced.

Die Latten können mit Schrauben oder dergleichen an den Schenkeln 8,9 befestigt werden. Die Schrauben können mit den Köpfen versenkt in einer Öffnung in der Außenwand der rohrförmigen Schenkel liegen, wobei der Schacht über eine entsprechende Bohrung in der Innenwand in die betreffende Latte geschraubt ist, wie in Figur 2 bei 19 gezeigt. Als Alternative kann die Öffnung in der Außenwand der rohrförmigen Schenkel 8,9 so groß sein, daß der Kopf ganz passieren kann und gegen die Innenwand zu ruhen kommt, wie bei 20 gezeigt.The slats can be attached to the legs 8, 9 with screws or the like. The screws can be countersunk with the heads in an opening in the outer wall of the tubular legs, the shaft being screwed into the relevant slat via a corresponding hole in the inner wall, as shown in FIG. 2 at 19. As an alternative, the opening in the outer wall of the tubular legs 8, 9 can be so large that the head can pass completely and come to rest against the inner wall, as shown at 20.

Figur 3 zeigt eine Abwandlung von Figur 2, wobei die Stirnwände 16,17 der rohrförmigen Schenkel sich einwärts als kurze Flansche 21,22 fortsetzen, die die Latten festhalten. Im gezeigten Beispiel liegen die Flansche in Falzen in den Latten.FIG. 3 shows a modification of FIG. 2, the end walls 16, 17 of the tubular legs continuing inwards as short flanges 21, 22 that hold the slats in place. In the example shown, the flanges are folded in the slats.

In der Zeichnung sind weiter noch schematisch Streben 23,24 angegeben, mit denen das Metallprofil 1 vertikal gestellt werden kann.In the drawing, struts 23, 24 are also shown schematically, with which the metal profile 1 can be placed vertically.

Zum Hochmauern einer (weiter nicht dargestellten) Wand werden zwei Mauerprofile der in Figur 1 gezeigten Art vertikal gestellt durch Streben 23 und 24, die an jeder gewünschten Stelle der aus Holz bestehenden Seitenflächen des Metallprofils 1 mit Hilfe von Nägeln oder dergleichen befestigt werden können. Mittels eines schräg eingeschlagenen Nagels im unteren Endabschnitt 7 kann dabei, falls gewünscht, das Mauerprofil 1 an einem Boden befestigt werden. Anschließend kann die Wand oder dergleichen gemauert werden.To wall up a wall (not shown further), two wall profiles of the type shown in FIG. 1 are placed vertically by struts 23 and 24, which can be fastened at any desired location on the wooden side faces of the metal profile 1 with the aid of nails or the like. By means of an obliquely driven nail in the lower end section 7, the wall profile 1 can, if desired, be fastened to a floor. The wall or the like can then be bricked up.

Zum Festnageln der Streben 23 und 24 kann jeweils eine andere Stelle ausgesucht werden, so daß eine feste Nagelverbindung erhalten wird. Wenn das untere Ende des Endabschnittes 7 durch häufiges schräges Einschlagen von Nägeln von Nagellöchern durchsiebt ist und ein nächster Nagel zu wenig Halt hat, kann der Endabschnitt etwas hinausgeschoben werden und kann anschließend das unbrauchbare Ende abgesägt werden. Der Zwischenraum, der hierdurch zwischen dem Endabschnitt und dem Mittelabschnitt entsteht, braucht in der Praxis nicht störend zu sein. Weiter können die Endabschnitte gegebenenfalls, nachdem sie schon ein oder mehrere Male abgesägt und hinausgeschoben worden sind, ganz durch neue Teile ersetzt werden.A different location can be selected for nailing the struts 23 and 24 so that a firm nail connection is obtained. If the lower end of the end section 7 is sifted through by frequent oblique hammering in of nails by nail holes and a next nail has too little hold, the end section can be pushed out a little and then the unusable end can be sawed off. The space that arises between the end section and the middle section does not have to be disruptive in practice. Furthermore, the end sections, if necessary after they have been sawed off and pushed out one or more times, can be completely replaced by new parts.

Es ist klar, daß die Erfindung nicht auf die dargestellte Ausführungsform beschränkt ist, sondern daß Änderungen im Rahmen der Ansprüche möglich sind. So kann jeder Abschnitt des Kernes aus einem Stück statt aus zwei Latten gebildet sein. Auch kann der Kern aus einem anderen nagelbaren Material als Holz hergestellt sein und können verschiedene Befestigungsmethoden verwendet werden, um zusammensetzende Teile der Kernabschnitte miteinander und diese Abschnitte mit dem Winkelprofil zu verbinden.It is clear that the invention is not limited to the illustrated embodiment, but that changes are possible within the scope of the claims. Each section of the core can thus be formed from one piece instead of two slats. The core can also be made of a nailable material other than wood and different fastening methods can be used to connect together the parts of the core sections and to connect these sections to the angle profile.

Auch ist es nicht strikt notwendig, daß die Endabschnitte sich bis am Metallprofil vorbei erstrecken, da die gemäß der Erindung verwendete Form des Metallprofils an sich schon eine erheblich verbesserte Nagelbarkeit an den Enden verschafft, auch ohne daß die Endabschnitte sich bis außerhalb des Metallprofils erstrecken.It is also not strictly necessary for the end sections to extend past the metal profile, since the shape of the metal profile used according to the invention is appropriate already significantly improved nailability at the ends, even without the end sections extending outside the metal profile.

Als zusätzlicher Vorteil eines Mauerprofils gemäß der Erfindung kann noch genannt werden, daß gegenüber den bekannten Metallprofilen, die mit einer praktisch ganz geschlossenen Aluminiumhülse versehen sind, relativ wenig Aluminium und relativ wenig Holz notwendig sind.As an additional advantage of a wall profile according to the invention can be mentioned that compared to the known metal profiles, which are provided with a practically completely closed aluminum sleeve, relatively little aluminum and relatively little wood are necessary.

Statt Holz können, falls gewünscht, aus anderem nagelbarem Material, z.B. aus (wiederverwendetem) nagelbarem Kunststoff, hergestellte Latten und/oder Klötze verwendet werden.Instead of wood, if desired, from other nailable material, e.g. made of (re-used) nailable plastic, slats and / or blocks.

Eine oder mehrere der Anliegeflächen 11,12,15,18 können, falls gewünscht, eine geriffelte oder gerillte Oberfläche aufweisen.One or more of the contact surfaces 11, 12, 15, 18 can, if desired, have a corrugated or grooved surface.

Um die sich bis außerhalb des Metallprofils erstreckenden Endabschnitte, wenn sie wenigstens verwendet werden, rundum nagelbar sein zu lassen, können diese als massive (ersetzbare), gegebenenfalls aus verschiedenen Teilen zusammengesetzte, aus Holz oder aus nagelbarem wiederverwendetem Kunststoff oder dergleichen hergestellte Klötze ausgebildet sein, die, soweit sie in das Metallprofil hineinragen, eingesägt und/oder ausgekerbt sind, um den Rohren 8,9,10 Raum zu bieten oder gerade, soweit sie sich außerhalb des Metallprofils erstrecken, mit Hilfe eines oder mehrerer Ausfüllteile verdickt sind, so daß der sich außerhalb des Metallprofils erstreckende Teil rundum gut erreichbar ist. Dieser Teil kann mit Vorteil dieselbe Außenform haben wie das übrige Metallprofil.In order to allow the end sections, which extend to outside the metal profile, if they are at least used, to be nailable all around, they can be designed as solid (replaceable) blocks, optionally composed of different parts, made of wood or of nailable re-used plastic or the like, which, insofar as they protrude into the metal profile, are sawn and / or notched in order to provide space for the pipes 8, 9, 10 or straight, as far as they extend outside the metal profile, are thickened with the aid of one or more filler parts, so that the part extending outside the metal profile is easily accessible all around. This part can advantageously have the same outer shape as the rest of the metal profile.

Auch könnten zur weiteren Erhöhung der Steifigkeit des Metallprofils noch zusätzliche Wände in den Rohren 8, 9 oder 10 angeordnet sein. Es kann dabei an diagonale Wände gedacht werden. Das Profil bleibt dann noch immer extrudierbar.Additional walls could also be arranged in the pipes 8, 9 or 10 to further increase the rigidity of the metal profile. You can think of diagonal walls. The profile then still remains extrudable.

Das Sichverwerfen des Holzes kann weiter durch Anwendung eines oder mehrerer von außen unsichtbaren Sägeschnitte quer zu den Fasern der Latten vermindert werden, wie in Figur 3 beispielsweise bei 25 gezeigt.The warping of the wood can be further reduced by using one or more externally invisible saw cuts across the fibers of the slats, as shown for example at 25 in FIG.

Derartige Abwandlungen werden erachtet, den Rahmen der Ansprüche nicht zu übersteigen.Such modifications are considered not to exceed the scope of the claims.
