Vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Betonkörpern, wie Säulen u. dgl., welche hohe axiale Druckfestigkeit besitzen sollen. Das Verfahren besteht darin, daß in den vollen Betonkörper außerhalb des Kerns eine Metallspirale eingelegt wird, so daß dieselbe konaxial zum Betonkörper gerichtet ist und die Windungen entsprechend nahe aneinander liegen.The present invention relates to a method for producing concrete bodies, such as columns and the like, which should have high axial compressive strength. The procedure consists in that a metal spiral is inserted into the full concrete body outside the core, so that the same is directed conaxially to the concrete body and the turns accordingly lie close to each other.
ίο Durch dieses Verfahren ist es möglich, Betonsäulen o. dgl. herzustellen, welche eine erheblich größere Druckfestigkeit besitzen als die nach den bisher bekannten Verfahren hergestellten, die beispielsweise mit am Umfange eingelegten, längslaufenden Zugstangen ausgerüstet würden, die in größerem Abstand durch Ringe o.dgl. verbunden werden mußten, um ein Ausbauchen der Zugstangen zu verhüten. ίο By this method, it is possible to produce concrete columns o. The like. Which one have significantly greater compressive strength than those produced by the previously known processes, which, for example, are equipped with longitudinal tie rods inserted on the circumference would that at a greater distance by rings or the like. had to be connected to prevent the tie rods from bulging.
Der Betonkörper muß nach vorliegender Erfindung in massiven Stücken ausgeführt werden, ohne bedeutende Hohlräume im Innern, da er sonst in diese ausweichen würde. Aus diesem Grunde sind von vornherein die bisher bekannten Rohre mit Umwicklung von Metallspiralen als Säulen o. dgl. ungeeignet.According to the present invention, the concrete body must be made in solid pieces without significant cavities inside, otherwise it will move into them would. For this reason, the previously known tubes are wrapped around from the outset of metal spirals as columns or the like. Unsuitable.
Ferner muß die Metallspirale ganz um den Beton herumgeführt werden; daß die Spirale aber außen auch mit Beton bekleidet ist, ist nicht unbedingt erforderlich, sondern bezweckt hauptsächlich nur, das Metall vor dem Einfluß der Luft zu schützen.Furthermore, the metal spiral must be guided all the way around the concrete; that the spiral but the outside is also clad with concrete, is not absolutely necessary, but intended mainly just to protect the metal from the influence of the air.
Die Wirkung der Metallspirale wird noch dadurch erhöht, daß man zu Draht gezogene Metallfäden verwendet, welche eine größere Festigkeit als gewalztes Metall haben.The effect of the metal spiral is increased by the fact that it is drawn into a wire Metal threads are used, which have a greater strength than rolled metal.
