Description
Zur Verankerung der Bewehrüngsstäbe im Stahlbetonbau werden bislang die Enden zu einem halbkreisförmigen Haken umgebogen, dessen lichter Krümmungsdurchmesser nach den Bestimmungen für die Ausführung von. Bauwerken aus Stahlbeton bei Betonstahl I mindestens gleich dem 2,5fachen, bei Betonstahl Il. und III mindestens gleich dien 5fachen Stahldurchmesser ist. An Stelle dieser Haken sollen nach der Erfindung die Bewehrungsstäbe des Betons am Ende Verdickungen erhalten, welche ein Durchziehen. der Stabenden bei Belastung verhindern. Soweit die Stäbe mit gestauchten Enden der Oberfläche des Betons zu nahe kommen und hierdurch dien Beton heraussprengen könnten, werden. sie auf der Baustelle unter geringem Winkel in dien Betonkörper hineingebogen.For anchoring the reinforcement bars in the reinforced concrete structure the ends bent over to form a semicircular hook, the clear diameter of which is of curvature according to the provisions for the execution of. Structures made of reinforced concrete for reinforcing steel I at least equal to 2.5 times, for reinforcing steel Il. and III at least equal is 5 times the steel diameter. Instead of these hooks, according to the invention the reinforcing bars of the concrete at the end receive thickenings that allow pulling through. of the rod ends under load. As far as the bars with compressed ends of the The surface of the concrete come too close and the concrete could burst out, will. they bent into the concrete body at a small angle on the construction site.
In der Zeichnung ist der Gegenstand der Erfindung in zwei Ausführungsbeispielen dargestellt. Abb. i stellt einen in Beton b eingelegten Rundstab a dar, der unter dem Winkel d abgebogen und mit einer nietkopfartigen Verdickung c seines Endes versehen ist. Abb. 2 zeigt in derselben Anordnung eignen Bewehrungsstab a mit keulenartiger Endverdickung e.In the drawing, the subject matter of the invention is shown in two exemplary embodiments. Fig. I shows a round rod a inserted in concrete b , which is bent at the angle d and provided with a rivet-head-like thickening c at its end. Fig. 2 shows in the same arrangement its own reinforcing bar a with a club-like end thickening e.
Der Vorteil der Verdickung ist einmal in der Ersparnis an Stahl zu erblicken (für Haken werden etwa 5 % der gesamten Bewehrung benötigt), zum anderen in der Verringerung der Facharbeiterlohnstunden auf der Baustelde. Auch können die Stabenden in dünnen Betonteilen gut verankert werden, während dieUnterbringung des Hakens mit dem vorgeschriebenen Krümmungshalbmesser oft Schwierigkeiten bereitet. Schließlich wird da, wo kein Haken gewünscht wird, z. B. bei Baustahlgewebe, die Haftungslänge verringert und somit auch in diesem Falle an Stahl gespart. Die Ausführung der Verdickung kann bereits im Stahlwerk (Kalt- oder Warmstauchung) erfolgen, so daß Rundstahl für Stahdbetonbauwerke grundsätzlich mit verdickten Stabenden geliefert werden könnte. Es steht aber auch nichts im Wege, Maschinen zu verwenden, die an Ort und' Stelle die Verdickung der Stabenden, etwa durch Pressen, vornehmen.The advantage of the thickening is the saving on steel too (about 5% of the total reinforcement is required for hooks), on the other hand in the reduction of skilled worker hours on the construction site. They can also Rod ends are well anchored in thin concrete parts while the Hook with the prescribed radius of curvature often causes difficulties. Finally, where no hook is desired, e.g. B. in structural steel mesh that Reduced adhesion length and thus also saved steel in this case. Execution the thickening can already take place in the steelworks (cold or hot upsetting), see above that round steel for reinforced concrete structures is always supplied with thickened rod ends could be. But nothing stands in the way of using machines that are on Make the thickening of the rod ends, for example by pressing.
