Description

?erfahren zur Herstellung von Betonbewehrungselementen Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Betonbewehrungselementen, die einer Ealtverfestigung unterzogen werden.Learn about the manufacture of concrete reinforcement elements The invention refers to a method of manufacturing concrete reinforcement elements that be subjected to age hardening.

Es ist bekannt, Betonbewehrungselemente dadurch herzustellen, daß man von einem Knüppel ausgeht, der dann in einer Anzahl von Stichen auf den Durchmesser des Bewehrungsstabes bzw. Bewehrungsdrahtes heruntergewalzt wird.It is known to produce concrete reinforcement elements in that one starts with a billet, which is then cut to the diameter in a number of stitches the reinforcing bar or reinforcing wire is rolled down.

Die Verankerungsrippen werden in den sogenannten Kalibrierstichen angewalzt. Nach dem Walzen findet dann eine Torsion der Stäbe bzw. Drähte statt, was zu einer Ealtverfestigung des Materials führt.The anchoring ribs are made in the so-called calibration stitches rolled. After rolling, the rods or wires are then twisted, which leads to an age hardening of the material.

Die vorliegende Erfindung beschreitet einen grundlegend neuen Weg und geht für die Herstellung der Betonbewehrungselemente von warmgewalztem Flachmaterial, insbesondere Warmbreitband, Bandstahl, Spaltband, Bleche oder dergleichen, aus. Dieses Material ist oft infolge verschiedener Umstände nicht für die Weiterverarbeitung im Ealtwalzwerk geeignet und wird daher abgewertet und für sonstige Zwecke verwendet.The present invention takes a fundamentally new approach and goes for the production of concrete reinforcement elements from hot-rolled flat material, in particular hot wide strip, steel strip, slit strip, sheet metal or the like. This material is often not for further processing due to various circumstances suitable in the Ealtwalzwerk and is therefore devalued and used for other purposes.

Die vorliegende Erfindung löst die vorstehend genannte Aufgabe dadurch, daß ein warmgewalztes Flachmaterial, z.B.The present invention achieves the above-mentioned object by that a hot rolled sheet, e.g.

Warmbreitband, Bandstahl, Spaltband, Bleche oder dergleichen in einer Slitting-Änlage in Streifen zerlegt wird, deren querschnitte quadratisch oder annähernd quadratisch sind und daß anschließend die Streifen durch Verwinden und/ oder Strecken kaltverfestigt werden.Hot wide strip, steel strip, slit strip, sheet metal or the like in one Slitting-Änlage is divided into strips, the cross-sections of which are square or approximately are square and that then the strips by twisting and / or stretching are work-hardened.

Gemäß einer bevorzugten Ausführungsform der Erfindung werden die auf dem warmgewalzten Flachmaterial nebeneinanderliegenden Reihen von Rippen, Riegeln oder dergleichen auf- bzw. eingewalzt, wobei der Abstand der Rippen- oder Riegelreihen kleiner als die Breite der in der Slitting-Anlage hergestellten Streifen ist.According to a preferred embodiment of the invention, the on the hot-rolled flat material adjacent rows of ribs, bars or the like rolled on or rolled in, the distance between the rows of ribs or bars is smaller than the width of the strips produced in the slitting system.

Es hat sich überraschenderweise gezeigt, daß beim Slitten der Streifen die unter Druck stehenden Messer die ganten der Streifen verfestigen, so daß keinerlei Kerbwirkung entsteht. Außerdem weist die Erfindung den Vorteil auf, daß äe nach der Breite des Materials der Walzprozeß für die Verwirklichung des gewünschten Durchmessers der Bewehrungselemente für eine große Anzahl von"Bewehrungselementen gleichzeitig in einer Anlage durchgeführt wird, so daß die Walskosten wesenXich herabgesetzt werden können.It has surprisingly been found that when slitting the strip the pressurized knives solidify the ganten of the strips so that nothing Notch effect arises. In addition, the invention has the advantage that äe after the width of the material of the rolling process for the realization of the desired diameter of reinforcement elements for a large number of "reinforcement elements" at the same time is carried out in a plant, so that the whale costs are significantly reduced can be.

Außerdem kann durch das erfindungsgemäße Verfahren eine wesentlich größere Ausstoßmenge erzielt werden.In addition, by the method according to the invention, an essential larger output can be achieved.

Das erfindungsgemäße Verfahren stellt ein völlig neues Anwendungsgebiet figur Warmmaterial dar. Die Abmessungen der Bewehrungsstäbe werden durch den Walzspalt sowie die Breitenmaße in der Slittinganlage eingestellt.The method according to the invention represents a completely new field of application Figure warm material. The dimensions of the reinforcing bars are determined by the roll gap and the width dimensions are set in the slitting system.

Es hat sich gezeigt, daß das Warmmaterial nach der Kaltverfestigung die technologischen Werte erreicht, die für Bewehrungsmaterial erforderlich sind.It has been shown that the hot material after work hardening reaches the technological values required for reinforcement material.
