Description

4040

Die Erfindung bezieht sich auf eine Abziehvorrichtung für Betonoberflächen od. dgl. mit einer Rüttelbohle, die mittels beidseitig angeordneter Fahrgestelle auf Schienen verfahrbar ist, wobei die Oberkanten der Schienen über und parallel zur abzuziehenden Betonlläche od. dgl. liegen.The invention relates to a pulling device for concrete surfaces or the like with a vibrating screed, which can be moved on rails by means of chassis arranged on both sides, the upper edges of the Rails above and parallel to the concrete surface to be removed or the like.

Bei einer bekannten Abziehvorrichtung dieser Art (US-PS 3 224 348) ist die Rüttelbohle über ihre Länge «juerschnittsgleich. Die Unwuchtmotoren sind im mittleren Bereich der Bohle angeordnet. Die beiden freien Enden der Rüttelbohle schwingen in der Eigenfrequenz #es schwingungsfähigen Systems und haben daher erheblich höhere Amplituden als die in erzwungenen Schwingungen bewegte Bohlenmitte. Das hat eine ungleichmäßige Verdichtung der Betondecke über die Länge der Bohle zur Folge.In a known pulling device of this type (US Pat. No. 3,224,348), the vibrating screed is over its length «Same cut. The unbalance motors are in the middle Area of the screed arranged. The two free ends of the vibrating beam vibrate at the natural frequency #es vibratory systems and therefore have considerably higher amplitudes than those in forced Vibrations in the middle of the plank. That has an uneven compaction of the concrete ceiling over the Length of the screed result.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Abziehvorrichtung der eingangs angegebenen Art, die Amplitude der Bohlenschwingung über die Länge der Rüttelbohle gleich zu machen und damit eine gleichmäßige Verdichtung des Betons der Decke zu erzielen.The invention is based on the object, in a pulling device of the type specified at the outset, which To make the amplitude of the screed oscillation equal over the length of the vibrating screed and thus a uniform one To achieve compaction of the concrete of the ceiling.

Diese Aufgabe wird dadurch gelöst, daß die Rüttelbohle beidseitig mit ihre Endschwingungen dämpfenden Anschlußstücken ausgestattet ist.This object is achieved in that the vibrating screed dampens its end vibrations on both sides Is equipped with fittings.

Dadurch wird der Vorteil erreicht, daß mit einfachen Mitteln eine Dämpfung von unerwünschten Schwingungen erreicht wird.This has the advantage that undesired vibrations can be damped with simple means is achieved.

Die Anschlußstücke sind zweckmäßig über Laschen an das Mittelstück der Rüttelbohle angeschraubt, wobei zwischen die Laschen von Anschluß- und Mittelstück jeweils Keile so angeordnet sind, daß die Anschlußstükke im stumpfen Winkel nach unten zeigen. Es können Keile mit verschieden großer Auflagefläche vorgesehen sein.The connecting pieces are expediently screwed onto the middle piece of the vibrating beam via brackets, whereby wedges are arranged between the tabs of the connecting piece and the middle piece so that the connecting pieces Point down at an obtuse angle. Wedges with differently sized contact surfaces can be provided be.

An Stelle durch Keile kann der gegenseitige Abstand der Laschen durch Stellschrauben bestimmt sein.Instead of wedges, the mutual spacing of the tabs can be determined by adjusting screws.

Die Anschlußstücke können verschieden lang und/oder verschieden schwer sein. Am Fahrgestell können zwei hintereinander liegende Rüttelbohlen angebracht sein.The connecting pieces can be of different lengths and / or of different weights. Can on the chassis two vibrating screeds lying one behind the other must be attached.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend an hand der Zeichnung erläutert. Es zeigtAn embodiment of the invention is explained below with reference to the drawing. It shows

F i g. 1 eine perspektivische Ansicht der Abziehvorrichtung undF i g. 1 is a perspective view of the puller and

F i g. 2 eine Seitenansicht eines Bohlenendes.F i g. 2 is a side view of a plank end.

In dieser Zeichnung ist ein Unwuchtmotor 1 mittig an einer Rüttelbohle 2 befestigt. An beiden Enden der Rütteibohle 2 sind nach oben herausragende Laschen 3 angeordnet, ferner an beiden Seiten Augenflansche 4. An die beiden Enden der Rüttelbohle schließen Anschlußstücke 5 an. Jedes Anschlußstück 5 hat an seinen beiden Enden Laschen 6 und 7, ferner an der Rüttelbohle 2 zugekehrten Seite einen Augenflansch 8. Die Lasche 6 ist mittels Bolzen 9 an einem Fahrgestell 10 angeflanscht. An der anderen Seite des Anschlußstücks 5 ist der Augenflansch 8 durch Bolzen 11 mit dem anliegenden Augenflansch 4 der Rüttelbohle 2 verbunden. Die Laschen 7 sind mit den Laschen 3 der Bohle 2 durch Boizen 12 verbunden. Die den Bolzen 11 zugeordneten Muttern sind festgezogen, die Muttern und Gegenmuttern an den Bolzen 12 aber so eingestellt, daß zwischen den Laschen 3 und 7 keilförmiger Raum 13 entsteht. Die Größe des keilförmigen Raums 13 kann durch den Bolzen 14 geändert werden. An die Stelle des Bolzens 14 kann auch ein in den Raum 13 geschobener Keil benutzt werden.In this drawing, an unbalance motor 1 is attached centrally to a vibrating beam 2. At both ends of the Rütteibohle 2 are arranged upwardly protruding tabs 3, furthermore eye flanges 4 on both sides. Connection pieces 5 connect to the two ends of the vibrating screed. Each connector 5 has on his both ends of tabs 6 and 7, and also on the side facing the vibrating screed 2 an eye flange 8. The Bracket 6 is flanged to a chassis 10 by means of bolts 9. On the other side of the connector 5, the eye flange 8 is connected by bolts 11 to the adjacent eye flange 4 of the vibrating beam 2. The tabs 7 are connected to the tabs 3 of the plank 2 by planks 12. The bolts 11 assigned The nuts are tightened, but the nuts and lock nuts on bolts 12 are set so that that between the tabs 3 and 7 wedge-shaped space 13 is formed. The size of the wedge-shaped space 13 can be changed by the bolt 14. Instead of the bolt 14, a space 13 can also be inserted pushed wedge can be used.

Der Raum 13 unterbricht die Bohle 2, dämpft deren Schwingungen stark und verhindert das Flattern der Bohlenenden.The space 13 interrupts the screed 2, dampens its vibrations strongly and prevents the fluttering Plank ends.
