Description
<Desc/Clms Page number 1>
Verfahren zur Erzeugung von Streckmetallrohren.
Vorliegende Erfindung hat ein Verfahren zur Erzeugung von Streckmetallrohren zum Gegenstande, welche hauptsächlich zur Armierung von Betonröhren bestimmt sind.
Das Wesen der Erfindung besteht darin, dass ein nahtloses Rohr mit Längsschlitzen versehen und hierauf aufgeweitet wird, beispielsweise durch Dorne.
Zwecks Anfertigung des Streckmetallrohres wird ein nahtloses Metallrohr mit gegeneinander versetzten Längsschlitzen in der bei Anfertigung von Streckmetall aus ebenen Blechen üblichen Weise versehen, wodurch-zwischen den Schlitzen miteinander zusammenhängende Streifen entstehen. Dieses nahtlose Rohr wird nun ausgeweitet) beispielsweise durch Dorne, wodurch unter Verkürzung des Rohres die Streifen schräg gestellt und gleichzeitig so verdreht werden, dass sie sich samt den Knotenstellen senkrecht zum Rohrumfang stellen, während sich die Schlitze zu im wesentlichen sechseckigen Öffnungen erweitern.
Dieses Streckmetallrohr kann schliesslich in irgendeiner geeigneten bekannten Weise in einen Betonmantel eingebettet werden. Nach dem Abbinden besitzt das Rohr, weil die Armierung nahtlos ist, eine hohe Festigkeit bei geringem Gewicht.

Process for the production of expanded metal tubes.
The subject of the present invention is a method for producing expanded metal pipes, which are mainly intended for reinforcing concrete pipes.
The essence of the invention is that a seamless tube is provided with longitudinal slots and then expanded, for example by means of mandrels.
For the production of the expanded metal tube, a seamless metal tube is provided with mutually offset longitudinal slots in the manner customary in the manufacture of expanded metal from flat metal sheets, whereby strips connected to one another are created between the slots. This seamless tube is now expanded), for example by means of mandrels, whereby the strips are inclined while shortening the tube and at the same time twisted so that they are perpendicular to the pipe circumference together with the nodes, while the slots widen to essentially hexagonal openings.
This expanded metal tube can finally be embedded in a concrete casing in any suitable known manner. After setting, the pipe has a high strength and low weight because the reinforcement is seamless.
