Abstract

1. A reinforcement rod for load-bearing members, comprising two parallel round rods, which are connected to one another by a bridging wall, having a circular cross section and discrete recesses form through holes.

Description

Die vorliegende Erfindung betrifft einen Bewehrungsstahl gemäss dem Oberbegriff des Patentanspruchs 1, ein Verfah­ren zu dessen Herstellung nach Patentanspruch 9 und eine Vorrichtung zur Durchführung des Verfahrens nach Patentan­spruch 10.The present invention relates to a reinforcing steel according to the preamble of patent claim 1, a method for its production according to patent claim 9 and a device for carrying out the method according to patent claim 10.

Es wurden schon viele Versuche unternommen, um ein günsti­ges Verhältnis zwischen der benötigten Festigkeit von Be­tonarmierungsstäben und dem Gewicht des Eisens zu erhalten. Beispielsweise in der AT-B 318 207 ist angegeben, Beweh­rungsstähle mit kreisförmigem Querschnitt einstückig und unverwunden miteinander zu verbinden, so dass die von zwei oder drei Kreisen begrenzten Querschnittsflächen in einer Breite die mindestens am halben Durchmesser der Kreise ent­spricht miteinander in Verbindung stehen.Many attempts have been made to achieve a favorable relationship between the required strength of concrete reinforcing bars and the weight of the iron. For example, AT-B 318 207 states that reinforcing steels with a circular cross section are connected to one another in one piece and without being twisted, so that the cross-sectional areas delimited by two or three circles are connected to one another in a width that corresponds to at least half the diameter of the circles.

Obwohl damit in zwei oder drei Ebenen ein vergrössertes Widerstandsmoment erzielt werden kann, wächst doch der Eisenquerschnitt und damit das Gewicht erheblich an.Although this is an enlarged one in two or three levels Resistance moment can be achieved, since the iron cross section and thus the weight increases considerably.

In der heutigen Zeit wird besonders grosser Wert auf gün­stige Ausnützung der Rohstoffe gelegt, um bei sparsamstem Materialaufwand grösstmögliche Festigkeiten zu erhalten. Dabei stellt auch die Fertigung einen nicht unwesentlichen Faktor dar, indem auch hier ökonomische Aspekte eine grosse Rolle spielen.Nowadays, great value is placed on the favorable use of raw materials in order to obtain the greatest possible strength while using the least amount of material. Manufacturing is also a significant factor in that economic aspects also play a major role here.

Es ist deshalb eine Aufgabe der Erfindung einen Bewehrungs­stab zu schaffen, bei dem bei kleinerem Stahldurchmesser und damit geringerem Gewicht pro Meter Stablänge höhere Widerstandsmomente erhalten werden.It is therefore an object of the invention to provide a reinforcement bar in which higher resistance moments are obtained with a smaller steel diameter and thus less weight per meter of bar length.

Erfindungsgemäss wird dies mit einem Bewehrungsstab gemäss den Merkmalen im unabhängigen Patentanspruch 1, ein Ver­fahren zur Herstellung eines solchen Bewehrungsstabes ist im Patentanspruch 9 und eine Vorrichtung zur Durchführung des Verfahrens ist im Patentanspruch 10 definiert.According to the invention, this is done with a reinforcement bar according to the features in independent claim 1, a method for producing such a reinforcement bar is defined in claim 9 and a device for carrying out the method is defined in claim 10.

Ausführungsbeispiele der Erfindung werden nachstehend an­hand der Zeichnung erläutert. Es zeigen:

  • Fig. 1 einen Querschnitt durch einen Bewehrungsstab nach der Erfindung,
  • Fig. 2 einen Querschnitt durch eine Anordnung von zwei Bewehrungsstäben mit Stegarmierung,
  • Fig. 3 eine Seitenansicht auf die Anordnung nach Fig. 2, und
  • Fig. 4 einen Querschnitt durch eine Anordnung mit drei Bewehrungsstäben nach Fig. 1.
Embodiments of the invention are explained below with reference to the drawing. Show it:
  • 1 shows a cross section through a reinforcing bar according to the invention,
  • 2 shows a cross section through an arrangement of two reinforcement bars with web reinforcement,
  • Fig. 3 is a side view of the arrangement of FIG. 2, and
  • 4 shows a cross section through an arrangement with three reinforcing bars according to FIG. 1.

Der erfindungsgemässe Bewehrungsstab gemäss Fig. 1 besteht aus zwei parallelen Stahldrähten 1,2, die durch eine Steg­wand 3 einstückig miteinander verbunden sind. Die Steg­wand 3 weist durchgehende Löcher 4 auf, die vorzugsweise äquidistant angeordnet sind.1 consists of two parallel steel wires 1, 2, which are connected in one piece by a web wall 3. The web wall 3 has through holes 4, which are preferably arranged equidistantly.

In einer beispielweisen Ausführungsform sind die Stahl­drähte 1,2 kreisrund und haben den gleichen Durchmesser d. Die beiden Drähte 1,2 sind um einen Abstand gleich d von­einander distanziert und die Stegwand 3 hat eine Dicke von d/2, wie auch in Fig. 1 angegeben ist.In an exemplary embodiment, the steel wires 1, 2 are circular and have the same diameter d. The two wires 1, 2 are spaced apart from one another by a distance equal to d and the web wall 3 has a thickness of d / 2, as is also indicated in FIG. 1.

Im Vergleich zu einem einfachen Draht aus Bewehrungsstahl mit einem Durchmesser von 4 cm, der ein Widerstandsmoment von 6,3 cm³ und ein Metergewicht von 9,9 kg/m hat, hat ein Bewehrungsstab gemäss Fig. 1 bei einem fünfmal grösse­ren Widerstandsmoment, nämlich 31,5 cm³ nur einen Betrag von 3,03 cm für d und daher ein Metergewicht von 14,9 kg/m. Dieser Vergleich zeigt, dass mit grösserem Widerstands­moment eine Einsparung von etwa 50% erzielt werden kann.Compared to a simple wire made of reinforcing steel with a diameter of 4 cm, which has a section modulus of 6.3 cm³ and a meter weight of 9.9 kg / m, a reinforcing bar according to FIG. 1 has a section modulus five times larger, namely 31.5 cm³, only 3 , 03 cm for d and therefore a meter weight of 14.9 kg / m. This comparison shows that with a larger section modulus a saving of about 50% can be achieved.

Besonders vorteilhafte Verwendungen sind somit Konstruktio­nen, bei denen eine hohe Festigkeit verlangt ist. Solche Konstruktionen sind beispielsweise die Träger in Hohlraum­bauten, die nach dem Ausbrechen des Gesteins eingebaut wer­den und eine Stütze für das ausgebrochene Gewölbe bilden, bis die Bewehrung mit Spritzbeton eingehüllt ist.Particularly advantageous uses are therefore constructions in which high strength is required. Such constructions are, for example, the girders in cavity structures, which are installed after the rock has broken out and form a support for the excavated vault until the reinforcement is covered with shotcrete.

Ein Beispiel für eine Armierung senkrecht zu Bewehrungs­stäben nach Fig. 1 ist in den Fig. 2 und 3 dargestellt. Es werden zwei Bewehrungsstäbe 10,20 flach nebeneinander angeordnet und zwischen diesen beiden Bewehrugnsstäben 10, 20 wird ein mäanderförmig gebogener Draht 30 mit kleinerem Durchmesser als d eingeschweisst.An example of a reinforcement perpendicular to reinforcing bars according to FIG. 1 is shown in FIGS. 2 and 3. Two reinforcing bars 10, 20 are arranged flat next to one another and a wire 30 with a smaller diameter than d is welded in between these two reinforcing bars 10, 20.

Eine weitere Variante ist in Fig. 4 dargestellt, bei der anstelle des mäanderförmigen Drahtes 30 in Fig. 3 ein wei­terer Bewehrungsstab 40 senkrecht auf die Ebene in der die Stegwände 3 der beiden Bewehrungsstäbe 10,20 liegen, zwi­schen diesen angeschweisst wird. Eine solche Anordnung könnte in gewissen Fällen direkt als Gurtträger verwendet werden.Another variant is shown in Fig. 4, in which instead of the meandering wire 30 in Fig. 3, another reinforcing bar 40 perpendicular to the plane in the Web walls 3 of the two reinforcement bars 10, 20 lie between which welding is carried out. Such an arrangement could in certain cases be used directly as a belt carrier.

Eine weitere, nicht dargestellte Variante wäre auch denk­bar, wenn der Bewehrungsstab 40 in Art von Fig. 3 oben an den mäanderförmigen Draht 30 angeschweisst würde. Dagegen könnte es auch für gewisse Fälle von Vorteil sein, wenn am freien Bogenteil des mäanderförmigen Drahtes 30 nur ein einfacher gerader Bewehrungsstab mit kreisförmigem Querschnitt angeordnet wäre.A further variant, not shown, would also be conceivable if the reinforcement bar 40 were welded to the meandering wire 30 at the top in the manner of FIG. 3. In contrast, it could also be advantageous in certain cases if only a simple straight reinforcement bar with a circular cross-section were arranged on the free arch part of the meandering wire 30.

Für die Herstellung solcher Bewehrungsstäbe gemäss Fig. 1 werden die Löcher in der Stegwand 3 gleichzeitig mit dem Warmwalzvorgang gestanzt. Diese Stanzung kann von der ei­nen Seite aus über einem Gegenhalter durchgeführt werden oder es können Walzen mit sich gegenüberstehenden Nocken vorgesehen sein, um Vertiefungen einzuprägen, so dass eine Membranwand bestehen bleibt, die dann anschliessend noch herausgeschlagen werden kann. Das Herausschlagen geschieht jedoch in demselben Arbeitsgang wie das Walzen.1, the holes in the web wall 3 are punched simultaneously with the hot rolling process. This punching can be carried out from one side via a counterholder or rollers with opposing cams can be provided in order to impress depressions so that a membrane wall remains which can then be knocked out. However, knocking out takes place in the same operation as rolling.
