Description

Hohlstab mit dreieckigem Querschnitt Es sind Masten bekannt, die aus einem oder mehreren Blechstreifen geformte Hohlstäbe von dreieckigem Querschnitt bilden. Zur Verstärkung sind bei diesen bekannten Hohlstäben an jeder Dreieckseite faltenartige Umbiegungen gebildet. Die Festigkeit solcher aus Blechstreifen geformter Hohlstäbe von dreieckigem Querschnitt zu erhöhen und sie für vielseitige Zwecke als Bauelemente verwendbar zu machen, ist der Zweck der Erfindung. Dieser ist dadurch erreicht, daß der aus einem oder mehreren Blechstreifen geformte Hohlstab von dreieckigem Querschnitt mindestens an einer seiner Längskanten, vorzugsweise an der Verbindungskante der Blechstreifenränder, in an sich bekannter Weise durch Umbiegungen oder Falzungen verstärkt ist.Hollow bar with triangular cross-section There are known masts from one or more sheet metal strips formed hollow rods of triangular cross-section form. For reinforcement, these are known hollow bars on each side of the triangle fold-like bends formed. The strength of those formed from sheet metal strips Increase hollow bars of triangular cross-section and use them for versatile purposes The purpose of the invention is to make it usable as structural elements. This is through it achieved that the hollow rod formed from one or more sheet metal strips of triangular Cross-section at least on one of its longitudinal edges, preferably on the connecting edge the sheet metal strip edges, in a known manner by bending or folding is reinforced.

Infolgedessen liegen die Verstärkungen an einer statisch günstigeren Stelle als bei den obenerwähnten bekannten Masten und es ergeben sich glatte Stabflächen, so daß mehrere Hohlstäbe, z. B. für Türpfosten und -rahmen, dicht aneinandergelegt schräge Fugen zur Frontfläche bilden und sich bündeln lassen. Solche Stäbe eignen sich insbesondere für Zeltgerüste, weil scharfe Kanten, an denen sich die Zeltbahn durchscheuern könnte, vermieden werden können.As a result, the reinforcements are statically more favorable Place than with the above-mentioned known masts and there are smooth rod surfaces, so that several hollow rods, for. B. for door posts and frames, placed close together Form inclined joints to the front surface and allow them to be bundled. Such bars are suitable Particularly suitable for tent frames because of the sharp edges on which the tent sheet is attached chafing through can be avoided.

Weitere Einzelheiten und Vorteile der Erfindung sind hierunter an Hand der Zeichnung beschrieben. Fig. 1 bis 6 zeigen verschiedene Ausführungsbeispiele der Querschnittsgestaltung des neuen Hohlstabes und Fig. 7 und 8 eine Anwendung; Fig.9 zeigt zwei aneinanderliegende Hohlstäbe nach der Erfindung.Further details and advantages of the invention can be found below Hand outlined drawing. FIGS. 1 to 6 show different exemplary embodiments the cross-sectional design of the new hollow rod and FIGS. 7 and 8 an application; 9 shows two adjacent hollow rods according to the invention.

Aus einem Blechstreifen oder aus einem anderen dünnen Material ist erfindungsgemäß ein Hohlstab 1 von dreiecksförmigem Querschnitt geformt, der an einer seiner Längskanten, und zwar, wie Fig. 1 zeigt, an der Verbindungskante der Blechränder 2 und 3, durch Umbiegen dieser Ränder und durch Hinzufügen eines Falzstreifens 4 in an sich bekannter Weise verstärkt ist. According to the invention, a hollow rod 1 of triangular cross-section is formed from a sheet metal strip or from another thin material, which at one of its longitudinal edges, namely, as shown in FIG a folded strip 4 is reinforced in a known manner.

Diese Verstärkung liegt im Vergleich zu den eingangs erwähnten bekannten Hohlstäben von dreieckigem Querschnitt an einer statisch erheblich günstigeren Stelle. Zugleich aber bietet sie eine erwünschte Möglichkeit, mit dem Stab irgendwelche Bauteile in an sich bekannter Weise niet- und schraubenlos durch Keile und/oder Klauen zu verbinden, wie das in den Fig. 7 und 8 für die Befestigung eines Maschendrahtzaunes mittels eines längs des Zaunes laufenden Spannbandes 5 gezeigt ist. Es genügen in diesem Fall einfach ein paar über die Winkelränder der Umbiegungen 2 und 3 gebogene Klauenbügel 6 und 7, in die ein das Band 5 am Hohlstab 1 festklemmender Rundkeil 8 eingetrieben ist.In comparison to the known hollow rods of triangular cross-section mentioned at the beginning, this reinforcement is at a statically considerably more favorable location. At the same time, however, it offers a desirable possibility of connecting any components to the rod in a manner known per se without rivets or screws by means of wedges and / or claws, as is shown in FIGS running strap 5 is shown. In this case, a couple of claw brackets 6 and 7 bent over the angular edges of the bends 2 and 3, into which a round wedge 8 clamping the band 5 on the hollow bar 1, is sufficient.

An Stelle eines winkelförmigen Falzstreifens 4 gemäß Fig. 1 kann man gemäß Fig.2 einen flachen Falzstreifen 11 zur weiteren Verstärkung der entsprechend abgebogenen Blechstreifenränder 9 und 10 verwenden oder man kann ganz ohne Falzstreifen eine Verstärkung aus den Blechstreifenrändern durch entsprechende Umbiegungen 12 oder 14 gemäß den Fig. 3 und 4 bilden. Außer an der Verbindungskante der Blechstreifenränder kann man auch, wofür die Fig. 3 ein Beispiel gibt, an den anderen beiden Stabkanten durch Umbiegungen 15 und 16 Verstärkungen bilden. Auch die Stabflächen lassen sich, wie das an sich bekannt ist, durch Verformungen 17 versteifen (vgl. Fig.4).Instead of an angular Falzstreifens 4 of FIG. 1 can be in accordance with Figure 2 a flat fold strip 11 9 and 10 used for further amplification of the correspondingly bent sheet metal strip edges or one can quite a reinforcement without fold strip from the sheet metal strip edges by respective bends 12 or 14 in accordance with the Figs. 3 and 4 form. In addition to the connection edge of the sheet metal strip edges, it is also possible, for which FIG. 3 gives an example, to form reinforcements on the other two bar edges by means of bends 15 and 16. As is known per se, the rod surfaces can also be stiffened by deformations 17 (see FIG. 4).

Wie die Fig. 5 und 6 erkennen lassen, sind Stahldrähte oder -seile 18 von hoher Festigkeit in entsprechende Einschnürungen der Kanten des Hohlstabes eingefalzt oder mittels der Dreiecksform des Stabquerschnittes entsprechenden Spannblechen oder -körpern 20 in den Stabkanten eingeklemmt. Solche Verstärkungen, wie auch das Einlegen einer Verstärkungseinlage 18 mittels eines Verbindungsstreifens 4a sind an sich bekannt.As can be seen in FIGS. 5 and 6, steel wires or ropes are used 18 of high strength in corresponding constrictions of the edges of the hollow rod folded in or by means of the triangular shape of the rod cross-section corresponding clamping plates or bodies 20 clamped in the rod edges. Such reinforcements, as well as that Insertion of a reinforcement insert 18 by means of a connecting strip 4a known per se.

Die neuen Hohlstäbe 1 können mit ihren glatten Wänden falzartig aneinanderliegende Türpfosten und Tor- oder Türrahmen bilden, wie Fig. 9 andeutet. Sie lassen sich aber auch wiederum mit ihren glatten Wänden aneinanderliegend bündeln zum Zweck der Herstellung von Bauelementen vielfacher Festigkeit. Anstatt durch Ineinanderbiegen (Falzen) lassen sich die Blechstreifenränder 2, 3 bzw. 9, 10 bzw. 11-, 14 an den Kanten des Stabes 1 durch Schweißen miteinander ummittelbar bzw. unter Vermittlung eines Verbindungsstreifens vereinigen und verstärken.The new hollow rods 1 can, with their smooth walls, form door posts and gate or door frames, as shown in FIG. 9. However, they can also be bundled together with their smooth walls for the purpose of producing components with multiple strengths. Instead of bending into one another (folding), the sheet metal strip edges 2, 3 or 9, 10 or 11-, 14 at the edges of the rod 1 can be joined together and reinforced by welding or by means of a connecting strip.

Im Bedarfsfall kann man den Hohlstab 1, wie an sich bekannt ist, mit seine Druck- und Knickfestigkeit erhöhenden Stoffen wie Beton oder mit Stoffen wie Schaumstoff usw., die thermisch isolieren, oder mit Sand, Kies oder Bims füllen, die akustische Schwingungen der Stabwände dämpfen.If necessary, the hollow rod 1, as is known per se, can be filled with materials such as concrete or with materials such as foam, etc., which increase its compressive strength and buckling strength, which thermally insulate, or fill the acoustic vibrations of the rod walls with sand, gravel or pumice dampen.
