KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist ein neues Verfahren zur Herstellung nietloser Gitterträger für Bauzwecke, und zwar insbesondere zur Verwendung im Eisenbetonbau.The invention relates to a new method for producing rivetless lattice girders for building purposes, in particular for use in reinforced concrete construction.
Das Wesen dieses neuen Verfahrens besteht darin, daß die verstärkten oder flanschartig ausgebildeten Gurte eines Profileisens mit Längsbohrungen und das Profileisen von beiden Gurten her mit abwechselnd angeordneten, bisThe essence of this new process is that the reinforced or flange-like trained belts of a profile iron with longitudinal holes and the profile iron of both Straps alternately arranged up to
ίο nahezu an den gegenüberliegenden Gurt reichenden Quereinschnitten versehen wird, dann durch Langziehen des eingeschnittenen Profileisens ein zickzackförmig verlaufender Metallstreifen mit verstärkten Ecken und in diesen befindlichen Bohrungen gebildet wird und in letztere die die Gurte bildenden Stäbe eingezogen werden.ίο almost reaching the opposite belt Cross cuts is provided, then by pulling the cut profile iron a zigzag metal strip with reinforced corners and in these located holes is formed and drawn into the latter the bars forming the straps will.
Das Verfahren ermöglicht Gitterträger mit T-, X-, U-, V- oder anderem Querschnitt herzustellen. Außerdem kann das Widerstandsmoment des Trägers durch Einziehen einer mehr oder minder großen Zahl von Längsstäben in die Metallstreifen den jeweiligen Verhältnissen angepaßt werden.The process enables lattice girders to be produced with T, X, U, V or other cross-sections. In addition, the section modulus of the girder can be adjusted by pulling in a more or less large number of longitudinal rods can be adapted to the respective conditions in the metal strips.

Fig. 3 eine Ansicht des zur Bildung des Gitterwerkes dienenden, mit Einschnitten versehenen Profileisens. 3 shows a view of the profiled iron provided with incisions and used to form the latticework.
Fig. 4 zeigt den Querschnitt eines aus den in der Fig. 1 dargestellten Elementen zusammengesetzten Gitterträgers und die Fig. 5 bis 13 einige weitere unter Benutzung verschiedener Profileisen nach dem neuen Verfahren gebildete Ausführungsformen von Gitterträgern.FIG. 4 shows the cross section of an assembled from the elements shown in FIG Lattice girder and FIGS. 5 to 13 some more using different ones Profile iron according to the new method formed embodiments of lattice girders.
Bei der in den Fig. 1 bis 3 veranschaulichten Ausführungsform ist der Gitterträger aus den beiden Rundeisen α und einem mit verstärkten Rändern versehenen Profileisenstück c gebildet. Dabei wird zunächst das Profileisenstück c mit je einer Längsbohrung d in jedem Gurt (Fig. 2) und von beiden Gurten her mit abwechselnd bis nahe an den gegenüberliegenden Gurt reichenden Quereinschnitten f versehen. Dann wird das so eingeschnittene Profileisen zweckmäßig nach Einführung des einen Rundstabes α so in die Länge gezogen, daß die zwischen den Einschnitten liegenden Stegteile c einen zickzackförmig verlaufenden Metallstreifen bilden. Durch die durchbohrten, verstärkten Ecken b dieses Streifens werden alsdann die Rundstäbe α bzw. der zweite Rundstab α eingezogen, wodurch die in Fig. 1 dargestellte einfache Form des Trägers entsteht.In the embodiment illustrated in FIGS. 1 to 3, the lattice girder is formed from the two round bars α and a profile iron piece c provided with reinforced edges. First, the profile iron piece c is provided with a longitudinal bore d in each belt (FIG. 2) and from both belts with transverse incisions f alternately reaching up to close to the opposite belt. Then the profile iron cut in this way is expediently drawn in length after the introduction of a round bar α so that the web parts c lying between the incisions form a zigzag metal strip. The round rods α and the second round rod α are then drawn in through the perforated, reinforced corners b of this strip, which results in the simple shape of the carrier shown in FIG. 1.
In der angegebenen Weise können auch durch die Verbindung mehrerer Rundstäbe a mittels solcher Zickzackstreifen Gitterträger von dreieckigem, mehreckigem oder anderem Querschnitt hergestellt werden; der aus der Fig. 4 ersichtliche ist namentlich für Säulen geeignet.In the manner indicated, lattice girders of triangular, polygonal or other cross-section can also be produced by connecting several round bars a by means of such zigzag strips; that shown in FIG. 4 is particularly suitable for columns.
Nach den Fig. 5 und 6 ist zur HerstellungAccording to FIGS. 5 and 6 is for production
des den Diagonalenzug bildenden Metallstreifens ein Profileisen von T- bzw. I-förmigem Querschnitt benutzt, und die daraus hergestellten Gitterträger sind in den Fig. io und ii in perspektivischer Ansicht dargestellt.of the metal strip forming the diagonal train is a profile iron with a T- or I-shaped cross-section used, and the lattice girders made therefrom are shown in Figs. io and ii in shown in perspective view.
Das in den Fig. 7 und 8 dargestellte Profil dient zur Herstellung von Gitterträgern von V-förmigem Querschnitt (vgl. Fig. 12), indem zwei nach entgegengesetzten Richtungen schräg gestellte Eisen (Fig. 7 und 8) zu einem Träger mit gemeinsamem Obergurt zusammengesetzt werden. In Fig. 9 ist schließlich noch ein Profil dargestellt, welches zur Herstellung von Gitterträgern mit U-förmigem Querschnitt nach Fig. 13 dient.The profile shown in Figs. 7 and 8 is used for the production of lattice girders of V-shaped cross-section (see. Fig. 12) by placing two inclined in opposite directions Asked iron (Fig. 7 and 8) assembled into a carrier with a common upper belt will. Finally, FIG. 9 shows a profile which is used for the production of Lattice girders with a U-shaped cross section according to FIG. 13 are used.
