Description
Aus mehreren Teilen zusammengesetzter, in senkrechter Richtung verstellbarer Arbeitsbalken für Betonstraßenfertiger Die Erfindung betrifft eine Vorrichtung zur maschinellen Dichtung von Beton oder ähnlichen Stoffen für die Herstellung von Straßendecken. Diesem Zweck dienende Maschinen sind in verschiedener Ausführung bekannt geworden. Zum Dichten des Betons werden dabei ein oder mehrere Arbeitsbalken benutzt, deren Arbeitsgang durch Anschlagen an die seitlich als Schalung dienenden Formschienen, durch welche die Höhe der Deckenschicht bestimmt ist, begrenzt wird. Der Wirkungsbereich dieser aus einem Stück bestehenden Arbeitsbohlen ist aber beschränkt, da das Stampfen von Unterschichten, insbesondere bei Anordnung von Eiseneinlagen, nicht möglich ist, da derartige Arbeitsbohlen nur in der Höhe der fertigen Straßendecke arbeiten können. Die Dichtung der Unterschicht muß in einem solchen Falle von Hand oder mit Preßluftstampfern bewirkt werden, was umständlich, zeitraubend und daher unwirtschaftlich ist.Assembled from several parts, adjustable in the vertical direction Working beams for concrete pavers The invention relates to a device for mechanical sealing of concrete or similar materials for the production of road surfaces. Machines serving this purpose have become known in various designs. One or more working beams are used to seal the concrete Work step by attaching to the side rails serving as formwork, by which the height of the ceiling layer is determined, is limited. The scope However, this one-piece work board is limited because of the tamping of sub-layers, especially with the arrangement of iron inlays, not possible is because such work piles only work at the height of the finished road surface can. The sealing of the lower layer must in such a case by hand or with Pneumatic rammers are effected, which is cumbersome, time-consuming and therefore uneconomical is.
Andererseits sind Betonstraßenfertiger bekannt, bei denen die.ganze Arbeitsbühne, an welcher die Arbeitsgeräte hängen, durch Schraubenspindeln in der Höhenlage verstellbar ist. Eine derartige Einrichtung hat den Nachteil, daß mit ihr die Schaffung einer genauen, gleichmäßigen Deckenoberfläche in der vorgeschriebenen Weise erschwert wird, da ein Anschlag für den Arbeitsbalken nicht vorbanden ist.On the other hand, concrete pavers are known in which the whole Working platform, on which the work equipment hang, through screw spindles in the Height is adjustable. Such a device has the disadvantage that with her creating an accurate, uniform ceiling surface in the prescribed Way is made more difficult because a stop for the working beam is not available.
Durch die Erfindung sollen die den bisher bekannten Einrichtungen anhaftenden Nachteile vermieden werden. Sie besteht darin, daß die Arbeitsbalken, abgesehen von ihren, die seitlich angeordneten Formschienen in ihrer tiefsten Stellung als Anschlag benutzenden Endstücke in der Höhenlage verstellbar sind und stellt eine Vereinigung von zwei an sich bekannten Merkmalen dar, nämlich Benutzung der Formschienen als Begrenzung des tiefsten Ganges der Arbeitsbalken und Verstellbarkeit der Arbeitsbalken in der Senkrechten. Dadurch soll eine genaue Anpassung der Arbeitsbalken an verschiedene Höhenlagen der Unterbetonschicht ermöglicht werden.The invention is intended to provide the previously known devices inherent disadvantages are avoided. It consists in that the working beams, apart from her, the laterally arranged mold rails in their lowest position as a stop using end pieces are adjustable in height and provides represents a union of two known features, namely use of the Shaped rails to limit the deepest aisle of the working beams and adjustability the working bar in the vertical. This is intended to allow precise adjustment of the working beams at different heights of the sub-concrete layer.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt.An embodiment of the subject matter of the invention is shown in the drawing shown.
Es bedeuten hierin rzl und a: die seitlich vorgesehenen Straßenformschienen. b1 und b, sind die Endstücke, während c das Mittelstück des mehrteiligen Arbeitsbalkens bildet, das in bezug auf die Endstücke in der Höhenlage beliebig verstellbar ist. Die Höhenverstellbarkeit dieses Mittelteiles erfolgt durch die Spindeln e, und e._, die diesen gegen die Endstücke a, und a. mit Hilfe der das Muttergewinde enthaltenden Bügel d, und d, verschieben.Here, rzl and a mean: the road form rails provided on the side. b1 and b are the end pieces, while c is the middle piece of the multi-part work beam forms, which is adjustable in height with respect to the end pieces. The height adjustment of this middle part is done by the spindles e, and e._, which these against the end pieces a, and a. with the help of the nut thread containing Move bracket d and d.
Die Arbeitsweise des Betonstraßenfertigers und insbesondere des Arbeitsbalken ist hierbei so, daß zunächst mit heruntergelassenem Mittelstück c die Betonunterschicht bearbeitet wird. Nachdem dann gegebenenfalls die Eiseneinlage gelegt ist und das Mittelstück des Arbeitsbalkens in die Höhe der Straßenoberfläche gehoben ist, wird die Betondecke in der üblichen Weise fertiggestellt.How the concrete paver works and especially the working beam is here such that initially with the center piece c lowered, the concrete sub-layer is processed. After then, if necessary, the iron insert is placed and that The middle section of the working beam is raised to the level of the road surface the concrete ceiling finished in the usual way.
