Description

Bewehrter Holzbalken Es ist bekannt, Holzbalken durch in Nuten der Außenseiten eingekittete Eiseneinlagen zu bewehren, um ihre Tragfähigkeit zu erhöhen.Reinforced wooden beams It is known to put wooden beams through in grooves of the Reinforcing iron inlays cemented on the outside in order to increase their load-bearing capacity.

Nach der Erfindung werden die tragenden Stoffe (Holz und Eisen) mittels eines geeigneten, ein Arbeiten des Holzes zulassenden Kittes fest verbunden. Die Nuten besitzen einen größeren Querschnitt als die einzulegenden Eisen, um eine starke Kittumhüllung der letzten zu ermöglichen, so daß durch die ausgleichende Wirkung der Kittfuge ein Verbund von großer Sicherheit und hoher Lebensdauer erzielt wird.According to the invention, the load-bearing materials (wood and iron) are means a suitable putty that allows the wood to work. the Grooves have a larger cross-section than the iron to be inserted in order to be strong Allow putty coating of the last, so that through the balancing effect the putty joint a bond of great security and a long service life is achieved.

Bei der Herstellung dieses Balkens werden in die Zug- und Druckzonen des Holzes Nuten parallel zur Faser eingefräst und in diese Eisenstäbe eingekittet, welche die im Holzbalken auftretenden Längskräfte anteilig nach Maßgabe des Elastizitätsverhältnisses aufnehmen. Die Kittschicht besteht aus einem am Holz und Eisen festhaftenden Material, dessen Elastizitätsmaß etwas über dem des Holzes liegt und dessen Wärmedehnungszahl sich zwischen denen von Holz und Eisen bewegt.When making this beam, the tension and compression zones are used the wood grooves are milled parallel to the grain and cemented into these iron bars, which the longitudinal forces occurring in the wooden beam proportionally according to the elasticity ratio take up. The putty layer consists of a material adhering to wood and iron, whose degree of elasticity is slightly higher than that of wood and its coefficient of thermal expansion moves between those of wood and iron.

In der Zeichnung zeigt Abb. z die Ausführungsform eines armierten Holzbalkens, während die Abb. a und 3 weitere Ausführungsformen von Stützen erkennen lassen. Abb. 4 gibt eine Einbettung der Eisen in Holz wieder.In the drawing, Fig. Z shows the embodiment of a reinforced Wooden beam, while Figs. A and 3 recognize further embodiments of supports permit. Fig. 4 shows an embedding of the iron in wood.

Die Rundeisen z sind mit dem Holzbalken r durch die in die Nuten 3 eingefüllte elastische Kittmasse 4 fest verbunden. Durch die Anordnung einer starken Kittfuge sowie durch die Wahl eines Kittstoffes von vorbeschriebenen Eigenschaften wird erreicht, daß die Dehnungsunterschiede zwischen Holz und Eisen nur mittelbar zur Auswirkung kommen, daß ferner durch die ausgleichende Wirkung der Kittfuge die Haftflächen geringer beansprucht und demzufolge die Sicherheit und Dauer der Verbundwirkung wesentlich erhöht werden.The round iron z are with the wooden beam r through the in the grooves 3 filled elastic cement compound 4 firmly connected. By arranging a strong Putty joint as well as by choosing a putty substance with the properties described above it is achieved that the expansion differences between wood and iron are only indirect come to the effect that furthermore by the compensating effect of the putty joint the Adhesive surfaces less stressed and consequently the security and duration of the bond effect can be increased significantly.
