KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft Hohlträger und ähnliche Hohlkörper aus Metall, die sich dadurch auszeichnen, daß ihre Tragfähigkeit, bezogen auf ihr Eigengewicht, die bish,er bekannten gleichartigen Erzeugnisse wesentlich übertrifft. Die Erfindung besteht darin, daß die Hohlkörper aus Blechen oder Bändern derart zusammengesetzt werden, daß aus der einen von zwei aneinander stoßenden. Kanten ausgeschnittene Lappen durch Löcher an dftr anderen Kante gesteckt und ohne Umbiegung vernietet werden.The invention relates to hollow beams and the like Hollow bodies made of metal, which are characterized in that their load-bearing capacity, related on their own weight, which is significantly higher than known products of the same type. The invention consists in that the hollow body is composed of sheet metal or strips in this way become that from the one of two abutting one another. Edges cut out Flap through holes on the other The edge can be inserted and riveted without bending.
Diese Art der Kantenverbindung ist zwar an und für sich bekannt. Sie ist aber auf die Aufgäbe, Bauteile von großen Abmessungen herzustellen, für deren Verwendungsfähigkeit das Verhältnis ihrer Tragfähigkeit zu ihrem Eigengewicht in Betracht kommt, bisher nicht angewendet worden. Diese Übertragung ergibt aber aus folgenden Gründen einen erheblichen Fortschritt.This type of edge connection is known per se. But she is on the surrender, To manufacture components of large dimensions, for their usability the Ratio of their load-bearing capacity to their own weight comes into consideration, so far not applied been. However, this transfer results in a significant one for the following reasons Progress.
Nur wenige einfache Querschnittsformen lassen sich unmittelbar durch Auswalzen erzeugen, und man ist daher schon seit längerer Zeit dazu übergegangen', in allen Fällen, wo . größte Tragfähigkeit bei kleinstem Eigengewicht verlangt wird, solche Bauteile aus einzelnen Blechstreifen oder Bändern zusammenzusetzen.Only a few simple cross-sectional shapes can be produced directly by rolling, and it has therefore been used for a long time ', in all cases where . The greatest load capacity with the smallest dead weight is required, such components from individual Assemble sheet metal strips or bands.
■Nach den bisher gebräuchlichen Verfahren setzen aber derartige Kantenverbindungen stets voraus, daß die Kante scharf winklig umgebogen wurde, um die erforderliche Fläche für eine Nietverbindung zu erzielen. Durch diese Art der Kantenverbindung war daher die Auswahl des Baustoffs beschränkt, da gerade solche Baustoffe, welche die größte bisher bekannte Zugfestigkeit zeigen, wie beispielsweise Federstahl, einige Aluminiumlegierungen, wie Duraluminium u. dgl., so spröde sind, daß scharfe Biegungen von Blechen aus solchen Baustoffen nicht gelingen, ohne daß an der Biegungsstelle Brüche oder mindestens Gefahrstellen auftreten, welche die. Brauchbarkeit der daraus hergestellten Erzeugnisse in Frage stellen.■ However, according to the methods commonly used up to now, such edge connections always set assume that the edge has been bent at a sharp angle to provide the required area for a To achieve riveted connection. With this type of edge connection, the choice was made of the building material is limited, as it is precisely those building materials that are the largest known to date Show tensile strength, such as spring steel, some aluminum alloys, such as Duralumin and the like are so brittle that sharp bends in sheet metal from them Building materials do not succeed without fractures or at least dangerous points occurring at the bending point, which the. Usefulness of the products made from it.
Mit Hilfe der gekennzeichneten Kantenverbindung durch Vernietung von Lappen, die durch Schlitze gesteckt werden, gelingt es dagegen, aus Materialien höchster Zugfestigkeit, die wegen ihrer großen Sprödigkeit auf keine andere bisher bekannte Weise zu solchen Erzeugnissen verarbeitet werden konnten, Hohlträger und andere Hohlkörper von günstigen Querschnittsformen ohne Schwierigkeit herzustellen und dadurch die Verhältnisse von Tragfähigkeit zum Gewicht zu erreichen, die nach der Rechnung diesen an sich bekannten und erstrebten, aber bisher aus gleich zugfestem Material nicht herstellbaren Formen zukommen sollen.With the help of the marked edge connection by riveting tabs, which are inserted through slots, on the other hand, are made from materials of the highest tensile strength, which because of their great brittleness in no other previously known way to such Products could be processed, hollow beams and other hollow bodies of cheap Making cross-sectional shapes without difficulty and thus the ratios of load-bearing capacity to achieve the weight, which according to the calculation these known and strived for, but so far from the same tensile strength Material should come to forms that cannot be manufactured.
Es ist Bedingung für die Erreichung dieses Erfolges, daß das Material nur in solchen Stücken verarbeitet wird, die sich aus den einfachsten Formen ohne erhebliche Biegungen bilden lassen. Vorzugsweise, wenn, nicht ausschließlich, kommt 1 die Form von Blechen und flachen Bändern in Betracht. Doppel-T-Träger mit zwei oder mehr Stegen, U-förmige Rohre und ähnliche Erzeugnisse, die sich beispielsweise durch Walzen überhaupt nicht herstellen lassen, aber auch Bauformen, die durch Walzen zu erhalten wären, wie Doppel-T-Träger mit einfachemIn order to achieve this success, the material must only be used in pieces that can be formed from the simplest forms without significant bends. Preferably, if not exclusively, is 1, the shape of metal sheets and flat ribbons into consideration. Double-T-beams with two or more webs, U-shaped tubes and similar products that cannot be produced at all by rolling, for example, but also designs that could be obtained by rolling, such as double-T-beams with simple
Steg, können aus den genannten ,Materialien gebildet werden, ohne daß dessen Ränder zu
Flanschen umgebogen, . zu Wulsten verdickt oder sonst deformiert werden.
In der Zeichnung istWeb can be formed from the materials mentioned without the edges of which are bent into flanges,. be thickened into beads or otherwise deformed.
In the drawing is

Fig. 2 ist eine Ansicht eines zweiten flachen ίο Blechstreifens C, an dessen Rand den Lappen B entsprechende Schlitze oder Löcher D vorgesehen sind.2 is a view of a second flat sheet metal strip C, on the edge of which slots or holes D corresponding to the tabs B are provided.
Fig. 3 ist ein Querschnitt eines Hohlbalkens, der dadurch gebildet ist, daß die Lappen B von zwei Bändern A durch die Löcher D von zwei Bändern C gesteckt und vernietet sind.Fig. 3 is a cross-section of a hollow beam which is formed in that the tabs B of two tapes A are inserted through the holes D of two tapes C and riveted.
Fig. 4 ist ein. Querschnitt eines Hohlträgers,Fig. 4 is a. Cross section of a hollow beam,
der dadurch gebildet ist, daß ein Band A nach Fig. 1 halbkreisförmig umgebogen ist und daß dessen Lappen B durch die Löcher D eines Bandes C gesteckt und vernietet sind.which is formed in that a band A according to FIG. 1 is bent over in a semicircle and that its tabs B are inserted through the holes D of a band C and riveted.
Fig. 5 ist ein Querschnitt eines Hohlbalkens, der dadurch gebildet ist, daß sowohl ein nach Fig. ι vorbereitetes Band A wie ein nach Fig. 2 vorbereitetes Band C beide bis zu einem rechten Winkel umgebogen sind, und daß dann die Lappen B des Bandes A durch die Löcher D des Bandes C hindurchgesteckt und vernietet sind.Fig. 5 is a cross-section of a hollow beam, which is formed in that both a band A prepared according to FIG. 1 and a band C prepared according to FIG. 2 are both bent to a right angle, and then the tabs B of the band A through the holes D of the band C and riveted.
Fig. 6 ist eine Ansicht eines zur Herstellung der Kantenverbindung in der gekennzeichneten Weise besonders geeigneten Lappens B in vergrößertem Maßstabe. Diese Figur veranschaulicht die Einzelheiten der Ausführung der Kantenverbindung gemäß der Erfindung. Um die Deformierung des Materials bei der Herstellung der Vernietung auf ein Mindestmaß zu beschränken, wird die Außenkante E der Lappen B hohl gestaltet, und je nach dem verwendeten Material werden die Abmessungen der Höhe A1 an den Enden des Lappens und der Höhe A2 in seiner Mitte gewählt. Versuche haben ergeben, daß bei besonders sprödem Material, wie z. B. Federstahl, A1 im Verhältnis zu A2 groß sein muß, während bei leichter fließendem Material der Unterschied kleiner zu wählen ist. 6 is a view of a tab B which is particularly suitable for producing the edge connection in the manner indicated, on an enlarged scale. This figure illustrates the details of the execution of the edge connection according to the invention. In order to minimize the deformation of the material when making the riveting, the outer edge E of the tabs B is made hollow, and depending on the material used, the dimensions of the height A 1 at the ends of the tab and the height A 2 in chosen its midst. Tests have shown that with particularly brittle material such. B. spring steel, A 1 must be large in relation to A 2 , while the difference is to be selected smaller for easier flowing material.
