Abstract

The press head (6) is provided with a vibration producing unit which rotates with the head at a predetermined speed. The vibrations in their amplitude and frequency are stagelessly regulatable. The vibration unit is fitted radially to the drive shaft (2) of the roller head. According to the hardness of the vibration element (9) a part or all of the vibrations can be transmitted to the press rollers (3) of the press head (6). ADVANTAGE - Unites the advantages of a roller head with those of vibrating compacting.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Betonrohren nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for producing concrete pipes according to the preamble of claim 1.

Die bekannten Maschinen zur Herstellung von bewehrten Betonrohren mit Rollenköpfe z. B. aus der DE 27 38 944 bzw. DE 35 30 953 bestehen aus einer senkrecht stehenden Rohrform und einem oder mehreren um die gemeinsame Längsachse rotierenden Rollenköpfen. Diese Rollenköpfe bestehen aus zwei ihren Aufgaben entsprechend unterschiedlichen Teilen. Der obere Teil ist als über eine Welle angetriebener Teller ausgelegt, auf dessen Oberseite drehbar gelagerte Preßrollen das zugeführte Material an die äußere Rohrform pressen. Ein Glättzylinder mit oder ohne einem zweiten Satz aufgebauter Preßrollen legt als zweites Element den genauen Innendurchmesser des entstehenden Rohres fest und bestimmt die Oberflächenqualität der Rohrinnenseite.The well-known machines for the production of reinforced concrete pipes with roller heads z. B. from DE 27 38 944 and DE 35 30 953 consist of a vertical tube shape and an or several roller heads rotating around the common longitudinal axis. These roller heads consist of two according to their tasks different parts. The upper part is as over a wave driven plate designed, on the top rotatably mounted Press rollers press the supplied material onto the outer tube shape. A smoothing cylinder with or without a second set built up Press rollers are the second element, the exact inner diameter of the resulting pipe and determines the surface quality the inside of the pipe.

Dabei ist es im Sinne einer effektiven Produktion nötig, den Rollenkopf sehr schnell umlaufen zu lassen und auch in kurzer Zeit über die gesamte Länge des Rohres hinwegzubewegen. It is necessary in the sense of effective production, the roller head to circulate very quickly and in a short time over the to move the entire length of the pipe.  

Bei den bisher gebräuchlichen Verfahren besteht dabei immer die Gefahr, daß keine einwandfreie Haftung zwischen Bewehrung und Beton erreicht wird, oder daß Bewehrungsschatten aufgrund von Verwindungen der Bewehrung während der Produktion entstehen. Außerdem entspricht die Oberfläche des Rohres innen und außen nicht immer der geforderten Güte.With the previously used methods, there is always the Risk of no perfect liability between reinforcement and Concrete is reached, or that reinforcement shadows due to The reinforcement is twisted during production. In addition, the surface of the pipe corresponds to the inside and outside not always of the required quality.

Aufgrund dieser Nachteile wird in modernen Verfahren noch zusätzlich durch Vibration verdichtet.Because of these disadvantages, modern processes also add compacted by vibration.

Dabei finden Verfahren Anwendung, deren Innendurchmesser durch einen Kern, der sich über die Gesamtlange des Rohres erstreckt, vorgegeben ist. Nach der Fertigstellung des Rohrs wird entweder der gesamte Kern in Schwingungen versetzt, siehe DE 22 16 648, oder aber die gesamte Schalung mit Kern über die Trägerplatte in Schwingungen versetzt, DE 31 15 181.Processes are used whose inner diameter is defined by a core that extends the entire length of the tube, is specified. After the pipe is finished, either entire core vibrated, see DE 22 16 648, or but the entire formwork with core over the carrier plate in Vibrations offset, DE 31 15 181.

Bei all diesen Verfahren besteht die Gefahr der Überrüttlung des Beton, wodurch sich im Rohr Rüttelnester bilden und Entmischungen stattfinden können. In der DE 40 22 089 wird ein Verfahren geschildert, in dem der Kern durch partielles Ansprechen verschiedener Rüttlereinheiten nicht mehr zentral in Schwingungen versetzt wird, um eben eine Überrüttlung zu vermeiden. Ein solches Verfahren ist in der Ausführung sehr komplex und der Aufbau des Kerns mit Rüttler sehr aufwendig.With all of these methods, there is a risk of overwhelming the Concrete, which causes vibrating nests and segregation in the pipe can take place. DE 40 22 089 describes a method described in which the core by partial response different vibrator units no longer vibrate centrally is moved to avoid overcrowding. Such one The procedure is very complex to implement and the structure of the Kerns with vibrator very expensive.

Die Erfindung betrifft eine Vibrationseinheit, die es ermöglicht sowohl die Fertigungsvorteile des Rollenkopfs mit denen des vibrierenden Verdichtens zu vereinen.The invention relates to a vibration unit that enables both the manufacturing advantages of the roller head with those of the vibrating one Unite compacted.

Fig. 1 zeigt einen konventionellen Doppelrollenkopf. Fig. 1 shows a conventional double roller head.

Der Verteilerkopf 1 wird über eine Welle 2 angetrieben. Durch den Reibungskontakt mit dem Betonmaterial werden die auf dem Verteilerkopf sitzenden Rollen 3 in eine gegenläufige Umdrehung versetzt.The distributor head 1 is driven via a shaft 2 . Due to the frictional contact with the concrete material, the rollers 3 seated on the distributor head are rotated in opposite directions.

Über eine zweite Welle 4 erhält der Preßkopf 6 ein zum Verteilerkopf 1 gegenläufiges Drehmoment. Der Preßkopf wird vom Glätteil 7 ummantelt, der für einen maßgenauen und glatten Innendurchmesser sorgt.Via a second shaft 4 , the press head 6 receives a torque opposing to the distributor head 1 . The press head is encased by the smoothing part 7 , which ensures a dimensionally accurate and smooth inner diameter.

Um jetzt eine optimale Verdichtung zu erreichen, wird in den Preßkopf ein oder mehrere Vibratoren 8 eingebaut, die mit dem Preßkopf selbst rotieren. Ein oder mehrere Schwingelemente 9 erlauben es, daß nach Einschalten des fest mit dem Glätteil 7 verbundenen Vibrators 8 dieses frei schwingen kann. Vorzugsweise ist die Schwingungseinrichtung radial zur Antriebswelle des Rollenkopfes und die Frequenz und Amplitude des Vibrators stufenlos wählbar. Diese Kombination zweier Verfahren erlaubt eine schnelle Produktion von äußerst hochwertigen Rohren.In order to achieve optimal compression, one or more vibrators 8 are installed in the press head, which vibrate with the press head itself. One or more vibrating elements 9 allow the vibrator 8, which is firmly connected to the smoothing part 7 , to vibrate freely after switching on. The vibration device is preferably continuously variable radially to the drive shaft of the roller head and the frequency and amplitude of the vibrator. This combination of two processes enables the rapid production of extremely high-quality pipes.
