Description

Zusammengesetzte Holzträger, bestehend aus einer Stegbohle ünd mit derselben verbundenen seitlichen Rippen, welche von, den Auflagern, der Druckzone folgend, schräg nach oben verlaufen und dort in waagerechte Spannriegel übergehen, sind bekannt.Composite wooden beams, consisting of a web plank and with the same connected lateral ribs, which of, the supports, the pressure zone following, run diagonally upwards and merge there into horizontal clamping bars, are known.

Die Erfindung besteht demgegenüber darin, daß die Rippen, mit der Stegbohle verleimt sind und daß "zwischen den oberen Enden der Rippen und den 'waagerechtem: Spannriegeln Schlußkeile eingetrieben "sind.The invention consists in the fact that the ribs with the Web planks are glued and that "between the upper ends of the ribs and the 'horizontal: Tension bolts locking wedges are driven in ".

Durch 'diese beiden Malnahmen werden dem erfindungsgemäßen 'Holzträger besonders günstige statische 'Eigenschaften verliehen. Der Verbund zwischen den Stegbohlen und den Holzrippen ist infolge der Verleimung sperrholzartig; die eingetriebenen Keile verspannen die Riegel und Holzrippen gegeneinander.By 'these two measures the' wooden support according to the invention given particularly favorable static 'properties. The network between the Bridge planks and the wooden ribs are plywood-like as a result of the gluing; the driven Wedges brace the bars and wooden ribs against each other.

In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar in Fig. i in Ansicht mit teilweisem Schnitt, in Fig. 2 im Grundriß, in Fig. 3 im Schnitt nach der Linie A-B und in Fig. q. im Schnitt nach der Linie C-D.In the drawing is an embodiment of the subject matter of the invention shown, namely in Fig. i in a view with partial section, in Fig. 2 in Plan view, in Fig. 3 in section along the line A-B and in Fig. Q. on average after the line C-D.

Eine hochkant gestellte Stegbohle e wird durch beidseitig angebrachte Holzrippen f verstärkt. Diese verlaufen von den Auflagerna, der Druckzone folgend, schräg nach oben, wo sie durch horizontale Spannriegel g und eingetriebene Schlußkeile h gegenseitig versteift werden. Die- Holzrippen f sind mit der Stegbohlee verleimt und vernagelt, ferner mittels durchgetriebener Randbolzen i mit ihr verankert. Durch die VeTleimung der schrägen Hblzrippen mit der Stegbahle entsteht ein festes Gefüge, weil die Längsfasern. der Konstruktionsteile einander überschneiden. Dadurch wird auch einer Rißbildung ,entgegengewirkt. Da die Hölzer schwachen Querschnitt besitzen, ergibt sich ein rascheres Austrocknen derselben.An edgewise plank e is attached on both sides Reinforced wooden ribs f. These run from the Auflagerna, following the pressure zone, obliquely upwards, where they are supported by horizontal clamping bolts g and driven end wedges h are mutually stiffened. The wooden ribs f are glued to the bridge board and nailed, further anchored to it by means of driven edge bolts i. By the gluing of the inclined wooden ribs with the web awl creates a solid structure, because the longitudinal fibers. of the construction parts overlap. This will also counteracts cracking. Since the timbers have a weak cross-section, the result is a more rapid drying out of the same.
