Description

Verfahren zum Aufspritzen von Mörtel o. dgl. Es ist bekannt, der Luft in Spritzgeräten für Mörtel o. dgl. durch schraubenlinig gewundene Kanäle eine Wirbelbewegung zu erteilen, um eine gute Vermischung des Wassers und des trocknen Baustoffs zu erzielen. Das fertige Gemisch tritt dann im wesentlichen in der Achsrichtung aus der Düse aus.Method for spraying mortar o. The like. It is known, the air In spraying devices for mortar or the like, a vortex movement through helically wound channels to allow a good mixing of the water and the dry building material achieve. The finished mixture then emerges essentially in the axial direction the nozzle off.

Die Erfindung will nun den Übelstand vermeiden, daß eine verhältnismäßig große Mörtelmenge beim Auftreffen auf die zu verputzende Fläche abprallt und hierbei verlorengeht. Dies wird dadurch erreicht, daß das Gemisch, das unter Wirbelung der Luft hergestellt wird, bis zum Auftreffen auf die zu verputzende Fläche in wirbelnder Bewegung gehalten wird. Infolgedessen prallen die Mörtelteilchen nicht einfach von dem Untergrund ab, sondern gleiten im Augenblick des Ruftreffens infolge der ihnen erteilten drehenden Bewegung auf oder in dem noch weichen Untergrund weiter, und zwar dahin, wo sie den geringsten Widerstand finden. Dies sind aber die noch lockeren und porigen Stellen des Putzes, die infolgedessen verdichtet werden.The invention now wants to avoid the disadvantage that a relatively large amount of mortar ricochets off when it hits the surface to be plastered and thereby get lost. This is achieved by the fact that the mixture, which swirls the Air is produced until it hits the surface to be plastered in swirling Movement is kept. As a result, the mortar particles do not simply bounce off the subsoil, but slide at the moment of the call as a result of them given rotating movement on or in the still soft ground, and to where they find the least resistance. But these are the more relaxed ones and porous areas of the plaster, which are compacted as a result.

In der Zeichnung ist eine Vorrichtung zur Ausführung des Verfahrens in einer Ausführung dargestellt.In the drawing is an apparatus for carrying out the method shown in one embodiment.

Abb. i ist ein Langschnitt, und Abb. 2 und 3 sind Querschnitte durch die Spritzdüse.Fig. I is a long section, and Figs. 2 and 3 are cross sections through the spray nozzle.

Die Mischdüse besteht aus dem kegelig sich verjüngenden Gehäuse i, das mit dralligen Zügen 2 versehen ist. Die Zuführung des Druckmittels (Luft, Wasser o. dgl.) erfolgt durch ein Rohr 3, das innerhalb des Gehäuses i schraubenlinig gebogen ist und das auf der inneren Seite Austrittsöffnungen 4. hat, die nicht strahlig nach der Achse zu gerichtet, sondern einseitig schräg angeordnet sind. Infolgedessen entsteht eine Drehkraft, die den aus dem Rohr 5 kommenden Mörtelstrom in drehende wirbelnde Bewegung versetzt. Diese Bewegung wird durch' den Drall 2 verstärkt, sie wird bis zum Austritt aus der Düse fortgesetzt, so daß das Gemisch diese Drehbewegung auch noch beim Auftreffen auf die zu verputzende Fläche hat.The mixing nozzle consists of the conically tapering housing i, which is provided with twisted trains 2. The supply of the pressure medium (air, water o. The like.) takes place through a tube 3, which is bent helically inside the housing i and that has outlet openings on the inner side that are not radiant directed towards the axis, but are arranged obliquely on one side. Consequently a turning force arises, which turns the mortar flow coming from the pipe 5 into turning whirling movement offset. This movement is reinforced by the twist 2, they is continued until it emerges from the nozzle, so that the mixture does this rotary movement even when it hits the surface to be plastered.

Auch bei Mörtelschleuderern, bei denen das fertige Gemisch dem Strahlrohr zugeführt wird, kann das -neue Verfahren verwendet werden. In diesem Falle wird durch das Rohr 3 Druckluft statt Wasser zugeführt, und es wird zweckmäßig diesem Gemisch in dem Rohr 5 durch eine Schnecke o. dgl. eine DrehbewegLing erteilt.Even with mortar extractors, where the finished mixture passes through the nozzle is supplied, the -new method can be used. In this case it will fed through the pipe 3 compressed air instead of water, and it is expedient this Mixture in the tube 5 by a screw or the like. A rotary movement is granted.
