Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand der Erfindung bezieht sich auf einen eisernen Gitterträger, welcher insbesondere zur Verwendung im Eisenbetonbau dienen soll und aus zwei getrennten, je durch einen Gurt und aus ihm herausgeschnittenen und abgebogenen Streben gebildeten Teile,^ zusammengesetzt ist.The invention relates to an iron lattice girder, which in particular to be used in reinforced concrete construction and of two separate ones, each by one Belt and parts formed from it cut out and bent struts, ^ assembled is.

Die Erfindung besteht darin, daß die freien Enden der Streben durch Schlitze in denThe invention consists in that the free ends of the struts through slots in the

ίο stehengebliebenen Querstegen der gegenüberliegenden Gurte gesteckt und auf die Querstege niedergebogen sind. Dadurch wird eine besonders einfache Herstellung der Träger ermöglicht. ίο the remaining crossbars of the opposite one Belts are inserted and bent down onto the crossbars. This enables a particularly simple production of the carrier.

Auf den Zeichnungen ist der Erfindungsgegenstand in mehreren Ausführungsbeispielen dargestellt. The subject matter of the invention is shown in several exemplary embodiments in the drawings.

Bei den in den Fig. 1 und 2 dargestellten Beispielen bestehen die beiden Gurte des Trägers je aus einem mehr oder weniger breiten, flachen Profileisen α, und die Streben b sind von abwechselnd aus beiden Gurten herausgeschnittenen und abgebogenen Zungen gebildet, deren freie Enden, wie aus Fig. 7 ersichtlieh ist, durch Schlitze in den stehengebliebenen Stegen c des gegenüberliegenden Gurtes hindurchgesteckt und dann auf diesen niedergebogen sind. Dadurch ist eine einfache Verbindung der beiden Teile des Gitterträgers erzielt.In the examples shown in Figs. 1 and 2, the two straps of the support each consist of a more or less wide, flat profile iron α, and the struts b are formed by alternately cut and bent tongues from both straps, the free ends of which, such as from Fig. 7 can be seen, inserted through slots in the remaining webs c of the opposite belt and then bent down on this. This achieves a simple connection between the two parts of the lattice girder.

Bei der in Fig. 3 dargestellten Ausführungsform ist der Träger aus einem flachen Profileisen hergestellt, welches außen mit einer längslaufenden Vertiefung d von der Breite der Streben versehen ist, und aus diesem schwächeren Teil sind die Streben in der beschriebenen Weise ausgeschnitten und herausgebogen.In the embodiment shown in Fig. 3, the carrier is made of a flat profile iron, which is externally provided with a longitudinal recess d of the width of the struts, and from this weaker part the struts are cut out and bent out in the manner described.

Die Verbindung der Streben b mit den zwischen den Ausschnitten der Gurte stehengebliebenen Stegen c ist, wie aus Fig. 6 ersichtlich, in der Weise gebildet, daß die freien Enden der Streben durch Schlitze der Stege c hindurchgesteckt und umgebogen sind; wegen der zurückliegenden Anordnung der Stege c stehen diese Enden hier, im Gegensatz zu den in Fig. i, 2 und 7 dargestellten Ausführungsformen, nicht aus dem Profil des Trägers hervor. Durch die Anordnung der längslaufenden Vertiefungen wird außerdem der Vorteil erreicht, daß die Gurte beliebig stark gemacht werden können, ohne daß dadurch die BiI-dung der Streben erschwert und diese zu dick werden; zugleich wird eine günstige Materialverteilung erreicht.The connection of the struts b with the webs c which have remained between the cutouts of the belts is, as can be seen from FIG. 6, formed in such a way that the free ends of the struts are pushed through slots in the webs c and bent over; Because of the rearward arrangement of the webs c, these ends, in contrast to the embodiments shown in FIGS. 1, 2 and 7, do not protrude from the profile of the carrier. The arrangement of the longitudinal depressions also has the advantage that the belts can be made as strong as desired without making the formation of the struts difficult and making them too thick; at the same time, a favorable material distribution is achieved.

Die Fig. 4 und 5 zeigen zwei Ausführungsformen für schwerere Träger mit den zu ihrer Herstellung verwendeten Profileisen, wobei mehrere Reihen von Verstrebungen nebeneinander angeordnet und entsprechend viele längslaufende Vertiefungen angebracht sind. Der in Fig. 4 veranschaulichte Träger ist in Fig. 8 im Schaubild besonders dargestellt.4 and 5 show two embodiments for heavier carriers with the to their Production used profile iron, with several rows of struts side by side arranged and a corresponding number of longitudinal depressions are attached. Of the The carrier illustrated in FIG. 4 is shown particularly in the diagram in FIG. 8.
