Description
Die Erfindung betrifft einen Bewehrungsstab oder -draht für Beton mit winklig zu seiner Achse mittels parallel zueinander verlaufender Rippen gebildeten Rillen, in denen aufeinanderfolgend Verbindungsrippen in Stabumfangsrichtung zueinander versetzt angeordnet sind.The invention relates to a reinforcing bar or wire for concrete with an angle to its axis by means Grooves formed by mutually parallel ribs, in which successively connecting ribs are arranged offset from one another in the circumferential direction of the rod.
Derartige Bewehrungsstäbe mit umlaufenden Rippen und Zwischenrippen sind durch die CH-PS 3 78 019 bekanntgeworden; dabei kann das gesamte Rippensystem zur Längsachse auch in einem Winkel angeordnet sein. Bei diesem Rippensystem ist die optimale Haftung im Beton dadurch beeinträchtigt, daß die Zwischenrippen durchweg parallel verlauf en.Such reinforcing bars with circumferential ribs and intermediate ribs are covered by CH-PS 3 78 019 known; The entire rib system can also be arranged at an angle to the longitudinal axis be. In this rib system, the optimal adhesion in the concrete is impaired by the fact that the intermediate ribs run parallel throughout.
Der Erfindung liegt die Aufgabe zugrunde, einen Bewehrungsstab zu schaffen, dessen Gleitwiderstand im
Beton groß ist
Ausgehend von einem Bewehrungsstab oder Bewehrungsdraht der eingangs genannten Art, wird die
Aufgabe dadurch gelöst, daß jeweils benachbarte Verbindungsrippen zueinander divergieren. Dadurch
werden trapezähnliche Vertiefungen am Stab geschaffen, und durch die wechselnde Rippenrichtung ist auch
bei starker Torsionsbeanspruchung ein hoher Gleitwiderstand gewährleistetThe invention is based on the object of creating a reinforcing bar whose sliding resistance in concrete is high
Starting from a reinforcing bar or reinforcing wire of the type mentioned at the outset, the object is achieved in that adjacent connecting ribs diverge from one another. This creates trapezoid-like depressions on the rod, and the changing direction of the ribs ensures a high level of sliding resistance, even under high torsional loads
Erfindungsgemäß können die Verbindungsrippen einen gleichen oder ungleichen Abstand zueinander aufweisen bzw. es können stets zwei Verbindungsrippen dichter nebeneinander angeordnet sein, ohne daß dadurch die Haftung im Beton ungünstig beeinflußt wird.According to the invention, the connecting ribs can have the same or different spacing from one another have or it can always be arranged two connecting ribs closer to one another without thereby the adhesion in the concrete is adversely affected.
Nach einem weiteren Merkmal kann die Breite der Verbindungsrippen gleich der Breite der zwischen zwei benachbarten Rillen angeordneten, winklig zur Stabachse verlaufenden parallelen Rippen sein, ohne daß die Hafteigenschaften beeinträchtigt sind; diese Ausführungsform hat den Vorteil eines gleichmäßigeren Materialgefüges an der Staboberfläche.According to a further feature, the width of the connecting ribs can be equal to the width of the between two be arranged adjacent grooves, at an angle to the rod axis extending parallel ribs without the Adhesive properties are impaired; this embodiment has the advantage of being more uniform Material structure on the rod surface.
Dazu trägt auch bei, wenn nach einer weiteren Ausführungsform die Höhe der Verbindungsrippen gleich der Rillentiefe istThis also contributes if, according to a further embodiment, the height of the connecting ribs is equal to the groove depth
Nachfolgend ist die Erfindung anhand der Zeichnung, in der ein Stab in Ansicht dargestellt ist, näher erläutert Am Bewehrungsstab bzw. Bewehrungsdraht 1 sind mit Ziffer 2 die Rillen bezeichnet, die zwischen den winklig zur Stabachse verlaufenden parallelen Rippen 3 gebildet sind.The invention is explained in more detail below with reference to the drawing, in which a rod is shown in perspective On the reinforcing bar or reinforcing wire 1, the number 2 denotes the grooves that between the parallel ribs 3 extending at an angle to the rod axis are formed.
In den Rillen 2 sind die Verbindungsrippen 4, 5 angeordnet, die zueinander divergieren.In the grooves 2, the connecting ribs 4, 5 are arranged, which diverge from one another.
