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.
