Abstract

A levelling device for producing a smooth surface on a sett paving bed is constructed, with a view to easy handling and neat working, so that the rule can lift the excess material with a cutting action by a projecting cutting edge and a rising ramp surface. With a collecting trough and with rollers to support the levelling rule, a transport truck for excess material can be provided at the same time.

Description

Die Erfindung betrifft eine Abziehvorrichtung zum Herstellen eines Feinplanums nach dem Oberbegriff des Anspruchs 1.The invention relates to a pulling device for producing a fine planum according to the preamble of claim 1.

Für das Abziehen eines Planums für Pflasterarbeiten werden typischerweise Abziehbohlen aus Holz oder Metall eingesetzt, in dem diese quer zu sich selbst längs der Oberseite des zuvor verdichteten Planums verschoben werden. Dabei sind zuvor Lehrlatten in das Planum so einzusenken, daß deren Oberkante im Niveau des herzustellenden Feinplanums liegt. Das Arbeiten mit diesen Abziehbohlen ist schon insofern umständlich und beschwerlich, als daß Pflasterbettmaterial wie z.B. Sand aus einer gebückten oder knienden Arbeitsstellung heraus verschoben werden muß.Screed planks made of wood or metal are typically used to remove a formation for paving work, in which they are moved transversely to themselves along the top of the previously compacted formation. Before doing this, the staff should be lowered into the formation so that the top edge is at the level of the fine formation to be produced. Working with these screeds is already cumbersome and burdensome in that plaster bed material such as e.g. Sand has to be moved out of a bent or kneeling working position.

Es sind auch bereits Abziehvorrichtungen entwickelt worden, die mittels Stielen handhabbar und dementsprechend in aufrechter Arbeitsstellung zu verwenden sind.Pullers have also been developed which can be handled by means of handles and can therefore be used in an upright working position.

Schließlich sind bereits Abziehbohlen zum Anbringen an maschinellen Arbeitsgeräten entwickelt worden, die jedoch einen entsprechenden maschinellen Aufwand voraussetzen und überdies durch das Gewicht der Arbeitsgeräte auf dem Planum besondere Probleme mit Verformungen des Untergrundes schaffen.Finally, screeds for attaching to machine tools have already been developed, which however require a corresponding amount of machine work and, moreover, create special problems with deformations of the ground due to the weight of the tools on the level.

In jedem dieser aus der Praxis bekannten Fälle ergeben sich insbesondere Probleme mit dem überschüssigen Material, welches auf das verdichtete Material aufgeschoben wird und von dort fortgeschafft werden muß, so daß sich leicht Bereiche ungleichmäßiger Dichte ergeben. Daraus ergibt sich oft die Notwendigkeit von Nacharbeiten Auch nach der Herausnahme von Lehrlatten aus dem fertiggestellten Planum wird ein Auffüllen und Nachbessern regelmäßig erforderlich.In each of these cases known from practice, problems arise in particular with the excess material which is pushed onto the compacted material and has to be removed from there, so that areas of uneven density easily result. This often results in the need for reworking. Even after the staff have been removed from the finished formation, refilling and reworking are regularly necessary.

Eine Abziehvorrichtung der gattungsbildenden Art, die auch mit einer Fangmulde versehen ist, ergibt sich aus der FR-A 761 296.A pull-off device of the generic type, which is also provided with a trough, results from FR-A 761 296.

Aufgabe der Erfindung ist es, eine Abziehvorrichtung zu schaffen, die leicht handhabbar ist und in einer schnellen Arbeitsweise ein Feinplanum herzustellen erlaubt, welches weitestgehend Nacharbeiten erübrigt.The object of the invention is to provide a pulling device which is easy to handle and which allows a fine planum to be produced in a rapid manner of operation, which largely eliminates reworking.

Gemäß der Erfindung wird diese Aufgabenstellung von einer Abziehvorrichtung nach dem Oberbegriff des Anspruchs 1 ausgehend mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.According to the invention, this task is solved by a pulling device according to the preamble of claim 1 with the characterizing features of claim 1.

Die erfindungsgemäße Abziehvorrichtung schafft eine schneidende oder schälende Abnehmbewegung, der das Material des Pflasterbetts einen erheblich geringeren Widerstand darbietet. Weiterhin wird vorgesehen, daß sich das überschüssige Material nicht vor dem Abziehlineal aufschiebt und von daher zusätzlichen Widerstand bietet, sondern daß es angehoben und in einer Fangmulde aufgenommen wird.The pull-off device according to the invention creates a cutting or peeling removal movement which offers the material of the plaster bed a considerably lower resistance. Furthermore, it is provided that the excess material does not slide on in front of the pull-off ruler and therefore offers additional resistance, but rather that it is raised and received in a catch trough.

Dies hat neben der Verringerung der bei der Abziehbewegung aufzubringenden Kräfte den Vorteil, daß das vorverdichtete Grobplanum nicht mit losem Material überdeckt wird und daß beim Fortbringen aufgeschobenen überschüssigen Materials auch verdichtetes Material abgehoben wird. Das hier hinter der Abziehvorrichtung verbleibende Material ist vielmehr von gleichmäßiger Dichte.In addition to reducing the forces to be exerted during the pulling-off movement, this has the advantage that the pre-compacted coarse subgrade is not covered with loose material and that, when excess material pushed on is removed, compacted material is also lifted off. Rather, the material remaining behind the puller is of uniform density.

Vorteilhaft ist auch, das Abziehlineal über Laufrollen abzustützen, die es erleichtern, überschüssiges Material, welches sich in den Fangmulden gesammelt hat, mit der Abziehvorrichtung abzufahren. Die Laufrollen können auch bei der Abziehbewegung für eine Abstützung auf Lehrlatten o. dgl. Nivellierhilfen sorgen.It is also advantageous to support the pull-off ruler with rollers that make it easier to run off excess material that has collected in the catch troughs with the pull-off device. The casters can also provide support on training slats or similar leveling aids during the pull-off movement.

Für die Abstützung auf Lehrlatten wird erfindungsgemäß insbesondere vorgesehen, daß die Laufrollen höhenverstellbar bezüglich des Abziehlineals sind, wobei der Verstellbereich regelmäßig so vorzusehen sein wird, daß die Laufrolle insgesamt oberhalb der Schneidenkante des Abziehlineals liegt. Es können dann Lehrlatten so an der Oberfläche eines Grobplanums angeordnet werden, daß die Schneidenkante unterhalb der Unterkante dieser Lehrlatten verläuft. Desgleichen können Lehrlatten auf einen bereits fertiggestellten Feinplanum-Streifen, auf eine bereits vorhandene Pflasterung o. dgl. aufgelegt werden - die Höhenverstellung erlaubt es, ein Feinplanum auf dem gewünschten Niveau herzustellen. Letzteres gilt auch für den Fall, daß bei der streifenweisen Herstellung eines Feinplanums einerseits ein Grobplanum und andererseits ein bereits fertiges Feinplanum vorliegt oder daß auf der einen Seite Bordsteinkanten als Bezugsniveau und Nivellierhilfe dienen.For the support on training slats it is provided according to the invention in particular that the rollers are height-adjustable with respect to the pull-off ruler, the adjustment area being regularly provided so that the roller is overall above the cutting edge of the pull-off ruler. Teaching staffs can then be arranged on the surface of a rough formation so that the cutting edge runs below the lower edge of these teaching staffs. Likewise, training slats can be placed on an already finished fine planum strip, on an existing paving or the like - the height adjustment allows a fine planum to be produced at the desired level. The latter also applies in the event that a coarse planum is present on the one hand in the production of a fine planum in strips and on the other hand an already finished fine planum is present or that curbs serve as a reference level and leveling aid on the one hand.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel für den Gegenstand der Erfindung näher erläutert ist. In der Zeichnung zeigen:

  • Fig. 1 Draufsicht auf eine Abziehvorrichtung (bei herausgebrochenem mittleren Teil),
  • Fig. 2 Schnitt nach Linie 11-11 in Fig. 1 und
  • Fig. 3 Seitenansicht der Abziehvorrichtung, in gleicher Richtung wie in Fig. 2 gesehen.
Further features and advantages of the invention result from the claims and the following description, in which an exemplary embodiment of the subject matter of the invention is explained in more detail. The drawing shows:
  • 1 top view of a puller (with the central part broken out),
  • Fig. 2 section along line 11-11 in Fig. 1 and
  • Fig. 3 side view of the puller, seen in the same direction as in Fig. 2.

Die in der Zeichnung insgesamt mit 1 bezeichnete Abziehvorrichtung umfaßt ein Abziehlineal 2, das typischerweise über mehrere Meter hinweg langgestreckt ist und dessen mittlerer Teil nur aus Gründen der Darstellung herausgebrochen gezeigt ist. Das Abziehlineal wird an seinen beiden seitlichen Stirnenden jeweils über eine Auflagervorrichtung 3 bzw. 4 abgestützt, die hinterseitig eine Laufrolle 5 bzw. 6 aufweist, die in einem sich in einer vorweigend horizontalen Ebene erstreckenden Rahmen 7 bzw. 8 gelagert ist, welcher vorderseitig eine Abtastkante 9 bzw. 10 ausbildet. Die Auflagervorrichtungen 3 und 4 sind jeweils über eine vorwiegend vertikal gerichtete Säule 11,12 mit einer Spindel 13, 14 und einer oberseitigen Handkurbel 15,16 für die Spindel höhenverstellbar mit dem Abziehlineal 2 verbunden. Die Führungsarme 7,8 sind weiterhin über Lenker 17,18 mit endseitigen Griffen 19,20 verbunden, die eine Handhabung der Vorrichtung in aufrechter Haltung ermöglichen.The pull-off device, designated overall by 1 in the drawing, comprises a pull-off ruler 2, which is typically elongated over several meters and the middle part of which is shown broken out only for the sake of illustration. The pull-off ruler is supported at both of its lateral ends by a support device 3 or 4, which has a roller 5 or 6 on the rear, which is mounted in a frame 7 or 8, which extends in a largely horizontal plane and which has a scanning edge on the front 9 or 10 trains. The support devices 3 and 4 are each connected via a predominantly vertically oriented column 11, 12 to a spindle 13, 14 and a top-mounted hand crank 15, 16 for the spindle with the pull-off ruler 2. The guide arms 7, 8 are also connected via links 17, 18 to end handles 19, 20, which enable the device to be handled in an upright position.

Die Abziehvorrichtung kann nun ähnlich einer herkömmlichen Abziehbohle über Leerlatten 21,22 bewegt werden, um bei Bewegung in Richtung eines Pfeils 23 aus einem Grobplanum 24 vor der Abziehvorrichtung ein Feinplanum 25 hinter dieser zu bilden. Allerdings ist es dabei nicht mehr erforderlich, daß die Leerlatten oder sonstige Nivellierhilfen bis unter das gewünschte Niveau des Feinplanums eingesenkt werden, vielmehr ermöglicht die hochgelegene Anordnung der Rollen 5,6 und insbesondere der Tastkanten 7,8 auch die Verwendung von höherliegenden Bezugskanten. Dementsprechend können auch die Ränder bereits verlegter Pflasterungen, parallellaufende Bortsteinkanten u. dgl. verwandt werden. Aus Fig. 2 und 3 ist u.a. der Höhenversatz zwischen der Oberkante des Feinplanums und der Oberkante der Leerlatte 21 bzw. 22 ersichtlich, wobei letztere nicht in gleicher Höhe zu liegen brauchen, vielmehr sind - insbesondere bei verschiedenen Nivellierhilfen - auch zueinander versetzte Bezugshöhen verwendbar.The pulling device can now be moved in a manner similar to a conventional screed over empty slats 21, 22, in order to move out of a coarse flat surface 24 before pulling off when moving in the direction of an arrow 23 device to form a fine planum 25 behind this. However, it is no longer necessary for the empty slats or other leveling aids to be sunk below the desired level of the fine planum. Rather, the elevated arrangement of the rollers 5, 6 and in particular the tracing edges 7, 8 also enable the use of higher reference edges. Correspondingly, the edges of pavements that have already been laid, parallel curbs and the like. Like. Be used. From Fig. 2 and 3, among other things, the height offset between the upper edge of the fine planum and the upper edge of the empty crossbar 21 or 22 can be seen, the latter need not be at the same height, but - especially with different leveling aids - offset reference heights can also be used.

Bei der Arbeit liegt sowohl die Abtastkante 9 bzw. 10 wie auch die Rolle 5 bzw. 6 der Auflagervorrichtungen 3,4 auf der zugehörigen Leerlatte 21 bzs. 22 auf, wobei die Abtastkante 9 bzw. 10 für die Höheneinstellung maßgeblich ist, da sie dem tiefstgelegenen Bereich des Abziehlineals benachbart ist. Die Abtastkante führt bei dem dargestellten Ausführungsbeispiel eine schleifende Bewegung aus, was gegenüber der ersatzweise möglichen rollenden Bewegung den Vorteil hat, daß von der Leerlatte 21 bzw. 22 aufliegender Sand o. dgl. Pflasterbettmaterial abgestreift wird. Es versteht sich, daß eine beidseitige Zweipunktauflagerung mit Abziehlineal und Rolle auch durch eine Einpunktauflagerung, sei sie schleifend oder rollend, ersetzt werden kann, sofern diese im wesentlichen lotrecht zum tiefstliegenden Bereichs des Abziehlineals angeordnet ist. Gewisse Änderungen im Anstellwinkel wirken sich dann nicht nennenswert auf das Niveau des Feinplanums aus.At work, both the scanning edge 9 and 10 as well as the roller 5 and 6 of the support devices 3, 4 lie on the associated empty batten 21 or. 22, wherein the scanning edge 9 or 10 is decisive for the height adjustment, since it is adjacent to the lowest area of the ruler. In the exemplary embodiment shown, the scanning edge carries out a grinding movement, which has the advantage over the rolling movement which is possible as an alternative that sand or similar material lying on the bed of the empty slat 21 or 22 is stripped off. It goes without saying that a bilateral two-point support with a ruler and roller can also be replaced by a one-point support, be it grinding or rolling, provided that this is arranged essentially perpendicular to the lowest area of the ruler. Certain changes in the angle of attack then have no significant effect on the level of the fine planum.

Aus Fig. 2 ist die vorteilhafte Form des Abziehlineals ersichtlich, welches insbesondere aus Gewichtsgründen aus einem abgekanteten Blech gefertigt ist. Bei Bewegung in Richtung des Pfeils 23 wird der Eingriff des Abziehlineals 2 zunächst durch eine Schneidenkante 26 gebildet, hinter der das Blech schräg ansteigend eine Aufgleitfläche 27 darbietet. Damit ist es möglich, den Sand oder sonstiges Pflasterbettmaterial oberhalb der Niveaulinie abzuheben, ohne daß das Material verschoben oder vorgewälzt wird. Zur Aufnahme des abgehobenen Materials wird hinter der Aufgleitfläche 27 eine Auffangmulde 28 gebildet, die rückseitig durch einen steil angestellten Rückenschild 29 begrenzt ist. Damit kann das Material aufgenommen werden und fällt nicht auf das frisch gefertigte Feinplanum zurück.The advantageous shape of the pull-off ruler can be seen from FIG. 2, which is made from a bent sheet metal in particular for reasons of weight. When moving in the direction of arrow 23, the engagement of the pull-off ruler 2 is initially formed by a cutting edge 26, behind which the sheet metal presents a sliding surface 27 rising obliquely. This makes it possible to lift the sand or other paving bed material above the level line without the material being shifted or rolled over. A receiving trough 28 is formed behind the sliding surface 27 to receive the material that is lifted off, which is delimited on the back by a steeply positioned back plate 29. This means that the material can be picked up and does not fall back on the freshly made fine planum.

Sobald die Mulde gefüllt ist, kann die Abziehvorrichtung 1 insgesamt als Karre verwandt und auf den Laufrollen 5,6 verfahren werden, um das überschüssige Pflasterbettmaterial abzutransportieren.As soon as the trough is filled, the pulling device 1 can be used as a cart as a whole and can be moved on the rollers 5, 6 in order to remove the excess plaster bed material.

Die so geschaffene Abziehvorrichtung ist insgesamt relativ leicht auszubilden, zumal die in der Zeichnung aus Darstellungsgründen weggebrochenen Mittelbereiche des Abziehlineals 2 den größten Teil der Abmessungen bestimmen. Eine solche von Hand zu bedienende Vorrichtung hat sich als vorteilhaft herausgestellt, da sie ein leichtes und sauberes Arbeiten ermöglicht, so daß sich der Einsatz maschineller Planierhilfen, die vom Aufwand und vom Eigengewicht her besondere Probleme schaffen, entbehrlich ist.The pull-off device created in this way is relatively easy to design overall, especially since the central regions of the pull-off ruler 2 which have broken away in the drawing for the sake of illustration determine the majority of the dimensions. Such a hand-operated device has been found to be advantageous because it enables easy and clean work, so that the use of mechanical leveling aids, which create special problems in terms of effort and weight, is unnecessary.

Das Abziehlineal kann der Länge nach unterteilt sein, wobei die Profilform eine flächige, formstabile Verbindung erleichtert. Damit ist auch die Möglichkeit geschaffen, die unterteilten Formbleche weiter zusammenzuschieben oder auseinanderzuziehen, um unterschiedliche Breiten herzustellen. Eine bevorzugte Ausführungsform sieht eine Dreiteilung der Bleche vor, so daß eine symmetrische Aus bildung mit einem Mittelteil und zwei zu diesen symmetrisch angeordneten Seitenteilen für das Abziehlineal 18 entsteht. Die Verbindung kann durch übliche Verschraubungen oder sonstige Klemmeinrichtungen geschaffen werden. Es ist aber auch möglich, hinter dem Rückenschild Verstrebungen zu einer Spindel-oder Zugseilverstellung anzubringen.The pull-off ruler can be divided lengthways, the profile shape facilitating a flat, dimensionally stable connection. This also creates the possibility of pushing the divided shaped sheets further apart or pulling them apart in order to produce different widths. A preferred embodiment provides a three-way division of the sheets, so that a symmetrical formation with a central part and two symmetrical side parts for the pull-out ruler 18 is formed. The connection can be created by conventional screw connections or other clamping devices. However, it is also possible to attach struts to a spindle or traction cable adjustment behind the back plate.
