Description
Aus dünnwandigem Material geformter Hohlstab für Baukonstruktionen oder dgl. Gegenstand der vorliegenden Erfindung bildet ein Hohlstab aus dünnwandigem Material z. B. Blech, der für vielseitige Zwecke als Bauelement verwend bar ist und der sich durch leichtes Gewicht bei ver- hältnismässig sehr hoher Festigkeit auszeichnet.
Erfindungsgemäss ist aus einem oder mehr als einem Streifen aus dünnwandigem Material, z. B. Blech, ein Hohlstab von dreieckigem Querschnitt ge bildet, der an einer seiner Längskanten, z. B. an der Verbindungskante der Streifenränder, durch Umbie gungen oder Falzungen verstärkt ist.
Solche Stäbe lassen sich vielseitig verwenden. So können mehrere Hohlstäbe z. B. für Türpfosten und -rahmen, dicht aneinandergelegt schräge Fugen zur Frontfläche bilden und sich bündeln lassen. Solche Stäbe eignen sich bei entsprechender Ausbildung ins besondere für Zeltgerüste, weil scharfe Kanten, an denen sich die Zeltbahn durchscheuern könnte, ver mieden werden können.
Weitere Einzelheiten und Vorteile sind hierunter anhand der Zeichnung beschrieben.
Die Fig. 1 bis 6 zeigen verschiedene Ausfüh rungsbeispiele der Querschnittsgestaltung des neuen Hohlstabes und die Fig. 7 und 8 eine Anwendung.
Fig. 9 zeigt zwei aneinanderliegende Hohlstäbe. Aus einem Streifen aus einem dünnwandigen Material, z. B. Blech, ist ein Hohlstab 1 von dreiecks- förmigem Querschnitt geformt, der an einer oder mehr als einer seiner Längskanten, und zwar, wie Fig. 1 zeigt, an der Verbindungskante der Blechrän der 2 und 3, durch Umbiegen dieser Ränder und durch Hinzufügen eines Falzstreifens 4 verstärkt ist. Diese Verstärkung liegt an der statisch günstigsten Stelle.
Zugleich aber bietet sie eine erwünschte Mög lichkeit, 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 Maschendraht zaunes mittels eines längs des Zaunes laufenden Spannbandes 5 gezeigt ist.
Es genügen in diesem Falle einfach ein paar über die Winkelränder der Umbiegungen 2 und 3 gebo gene Klauenbügel 6 und 7, in die ein das Band 5 am Hohlstab 1 festklemmender Rundkeil 8 eingetrieben ist.
Anstelle eines winkelförmigen Falzstreifens 4 ge- mäss Fig. 1 kann man gemäss Fig. 2 einen flachen Falzstreifen 11 zur weiteren Verstärkung der entspre chend 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 Stab kanten durch Umbiegungen 15 und 16 Verstärkun gen bilden. Auch die Stabflächen lassen sich, wie das an sich bekannt ist, durch Verformungen 17 verstei fen, vgl. Fig. 4.
Wie die Fig. 5 und 6 erkennen lassen, sind Stahl drähte oder -seile 18 von hoher Festigkeit in entspre chende Einschnürungen der Kanten des Hohlstabes eingefalzt oder mittels der Dreieckform des Stabquer- schnittes entsprechenden Spannblechen oder -kör- pern 20 in den Stabkanten eingeklemmt. Solche Ver stärkungen,
wie auch das Einlegen einer Verstär kungseinlage 18 mittels eines Verbindungsstreifens 4a sind an sich bekannt.
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 Zwecke der Herstellung von Bauelementen vielfacher Festigkeit. Anstatt durch Ineinanderbiegen (Falzen) lassen sich die Blechstreifenränder 2, 3 bzw. 9, 10 bzw. 12, 14 an den Kanten des Stabes 1 durch Schweissen mit einander unmittelbar bzw. unter Vermittlung eines Verbindungsstreifens vereinigen und verstärken.
Im Bedarfsfalle 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 Schwin gungen der Stabwände dämpfen.
Formed from thin-walled material hollow rod for building structures or the like. The subject of the present invention forms a hollow rod made of thin-walled material z. B. sheet metal, which can be used as a component for a variety of purposes and which is characterized by its light weight and relatively high strength.
According to the invention is made of one or more than one strip of thin-walled material, for. B. sheet metal, a hollow bar of triangular cross-section ge forms, which at one of its longitudinal edges, z. B. at the connecting edge of the strip edges, by Umbie conditions or folds is reinforced.
Such bars can be used in many ways. So several hollow rods z. B. for door posts and frames, close together to form inclined joints to the front surface and can be bundled. With appropriate training, such rods are particularly suitable for tent frames because sharp edges on which the tent sheet could rub through can be avoided.
Further details and advantages are described below using the drawing.
1 to 6 show various Ausfüh approximately examples of the cross-sectional design of the new hollow rod and FIGS. 7 and 8 an application.
Fig. 9 shows two adjacent hollow rods. From a strip of thin-walled material, e.g. B. sheet metal, a hollow bar 1 is formed of triangular cross-section, which at one or more than one of its longitudinal edges, namely, as Fig. 1 shows, at the connecting edge of the Blechrän the 2 and 3, by bending these edges and through Adding a folding strip 4 is reinforced. This reinforcement is at the statically most favorable point.
At the same time, however, it offers a desired possi bility to connect any components in a known manner without rivets and screws by wedges and / or claws, as shown in FIGS. 7 and 8 for the attachment of a wire mesh fence by means of a longitudinal of the fence running tension band 5 is shown.
In this case, a couple of bent over the angular edges of the bends 2 and 3 are sufficient claw brackets 6 and 7, into which a round wedge 8 clamping the band 5 on the hollow bar 1 is driven.
Instead of an angular folding strip 4 according to FIG. 1, a flat folding strip 11 can be used according to FIG according to FIGS. 3 and 4 form.
Except at the connecting edge of the sheet metal strip edges you can also, for which Fig. 3 gives an example, on the other two rod edges by bends 15 and 16 form reinforcements. As is known per se, the rod surfaces can also be stiffened by deformations 17, cf. Fig. 4.
As can be seen in FIGS. 5 and 6, steel wires or ropes 18 of high strength are crimped into corresponding constrictions in the edges of the hollow bar or clamped into the bar edges by means of the triangular shape of the bar cross-section corresponding clamping plates or bodies 20. Such reinforcements
as well as the insertion of a reinforcement insert 18 by means of a connecting strip 4a are known per se.
The new hollow rods 1 can, with their smooth walls, form door posts and gate or door frames, as shown in FIG. 9. But 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 12, 14 at the edges of the rod 1 can be combined and reinforced by welding with one another directly or by means of a connecting strip.
If necessary, the hollow bar 1, as is known per se, can be filled with substances that increase its compressive strength and buckling strength, such as concrete or with substances such as foam, etc., which thermally insulate, or fill it with sand, gravel or pumice, the acoustic Schwin dampen the bar walls.
