Bewehrungseinlage für Eisenbetonbauten.
EMI1.1
<Desc/Clms Page number 2>
Bei einer solchen Ausbildung eines verwundenen als Bewehrung dienenden Einzelstabes zeigt sich, dass das Haftvermögen des Stabes im Beton ebenso gross ist wie bei zwei miteinander verwundenen Rundeisen bekannter Bauart. Ausserdem kann bei diesem neuen Bewehrungseisen die Vergütung durch die Verwindung ebenso weit getrieben werden wie bei den bekannten, aus zwei Rundeisen bestehenden Bewehrungseinlagen, nachdem bei der Verwindung die Vergütung abhängig ist von der Reckung und diese wieder abhängig ist vom Abstand des Massenteilchens von der Verwindungsachse.
Bei dem Eisen gemäss der Erfindung ist es von besonderem Vorteil, dass man die üblichen Querschnitts-und Bemessungstafeln ohne weiteres verwenden kann, nachdem die Abmessungen des Bewehrungseisens gemäss der Erfindung im wesentlichen gleich den Abmessungen der bekannten, aus zwei miteinander verwundenen Rundeisen bestehenden Bewehrungseisen sind. Ein weiterer Vorteil bei Verwendung v. on Bewehrungseisen gemäss der Erfindung ergibt sich daraus, dass man durch die
EMI2.1
einer aus zwei miteinander verwundenen Rundeisen bestehenden Bewehrungseinlage nicht ersetzen konnte, da sonst der Durchmesser dieser Einzelrundstäbe zu klein gewesen wäre.

Reinforcement insert for reinforced concrete structures.
EMI1.1
<Desc / Clms Page number 2>
In the case of such a design of a twisted single bar serving as reinforcement, it is found that the adhesive strength of the bar in the concrete is just as great as with two twisted round bars of known design. In addition, with this new reinforcing iron, the compensation can be driven just as far through the twisting as with the known reinforcement inserts consisting of two round bars, since the compensation for the twisting depends on the stretching and this again depends on the distance of the mass particle from the torsion axis.
With the iron according to the invention, it is particularly advantageous that the usual cross-sectional and dimensioning tables can be used without further ado, since the dimensions of the reinforcing iron according to the invention are essentially the same as the dimensions of the known reinforcing iron consisting of two round bars twisted together. Another advantage of using v. on reinforcing iron according to the invention results from the fact that one through the
EMI2.1
could not replace a reinforcement insert consisting of two round bars twisted together, since otherwise the diameter of these individual round bars would have been too small.
