Die dargestellte Einbaubohle umfaßt eine Grundbohle 1 vorbestimmter Breite, die an einem Straßenfertiger angeordnet und mit zwei mittleren ste­henden Wangen 2 verbunden ist, deren Hauptebenen sich in Fahrtrichtung des Straßenfertigers erstrecken. Auf jeder Seite der mittleren Wangen2 ist ein sich seitlich nach außen erstreckender Ausfahrzylinder 3 vorgesehen, diese sind mit nicht dargestellten Druckmittelleitungen zu deren Ein- bzw. Ausfahren verbun­ den. Die beiden Ausfahrzylinder 3 dienen zum Ausfahren von Ausfahrbohlen 4, die in eingefahrenem Zustand hinter der Grundbohle 1 angeordnet sind und die halbe Breite der Grundbohle 1 besitzen.The screed shown comprises a basic screed 1 of a predetermined width, which is arranged on a paver and is connected to two central upright cheeks 2, the main planes of which extend in the direction of travel of the paver. On each side of the middle cheeks 2 there is an extension cylinder 3 which extends laterally outwards and is connected to pressure medium lines (not shown) for their entry and exit the. The two extension cylinders 3 are used to extend extension screeds 4, which are arranged behind the base screed 1 in the retracted state and have half the width of the base screed 1.

Die Ausfahrbohlen 4 sind jeweils mit einer äußeren verschiebbaren Wange 5, an der der jeweilige Ausfahrzylinder 3 angreift, und mit einer inneren verschiebbaren Wange 6 versehen. Die äußere Wange 5 ist über wenigstens eine Führungsstange 7 mit der inneren Wange 6 verbunden. Die Wange 6 nimmt eine La­gerbuchse 8 auf, die den Ausfahrzylinder 3 im Bereich seines Außenrohrs 3′ umgreift, verschiebbar aufnimmt und führt. Der Ausfahrzylinder 3 ist am au­ßenseitigen Ende seines Außensrohrs 3′ über einen Flansch 3˝ mit einem Ver­schiebebock 9 fest verbunden, der seinerseits zwei miteinander verbundene, zur Wange 2 parallele Platten 10 umfassen kann und ist mit Führungsbuchsen 11 für die Führungsstange(n) 7 versehen. Der Flansch 3˝ fluchtet bei eingefahrener Ausfahrbohle 4 mit der Außenkante der Grundbohle 1.The extending screeds 4 are each provided with an outer displaceable cheek 5, on which the respective extending cylinder 3 engages, and with an inner displaceable cheek 6. The outer cheek 5 is connected to the inner cheek 6 via at least one guide rod 7. The cheek 6 receives a bearing bush 8, which engages around the extension cylinder 3 in the region of its outer tube 3, slidably receives and guides. The extension cylinder 3 is fixedly connected at the outside end of its outer tube 3 'via a flange 3' with a sliding block 9, which in turn can comprise two plates 10 connected to one another and parallel to the cheek 2 and is provided with guide bushings 11 for the guide rod (s) 7 . The flange 3˝ is aligned with the extended screed 4 with the outer edge of the base screed 1.

Die jeweilige Seitenwange 12 der Grundbohle 1 trägt eine Führung 13, die sich im Bereich über der Grundbohle 1 mindestens über die Breite des Ver­schiebebocks 9 erstreckt und nach außen mindestens um die Breite des Ver­schiebebocks 9 plus die zum Ausfahren der Ausfahrbohle 4 um die halbe Breite der Grundbohle notwendige Strecke ragt. Der Verschiebebock 9 ist längs der Führung 13 mittels eines Zylinders 14 verschiebbar, der zwischen der Wange 2 und dem Verschiebebock 9 wirkt. Die Führung 13 besitzt im dargestellten Aus­führungsbeispiel zwei sich parallel zur Ausfahrrichtung der Ausfahrbohle 4 erstreckende Leisten 15 mit einander zugewandten seitlichen Führungsnuten 16, wobei die Führung 13 eine Führungsplatte 17 an der Unterseite des Verschiebe­bocks 9 aufnimmt, die seitlich entsprechend den Führungsnuten 16 profiliert ist. Der Verschiebebock 9 bzw. seine Führungsplatte 17 (oder mit entsprechen­dem Abstand zueinander angeordnete Führungsleisten) ist ausreichend breit, damit eine gute Führung beim Verstellen des Verschiebebocks 9 gewährleistet wird.The respective side cheek 12 of the base screed 1 carries a guide 13, which extends in the area above the base screed 1 at least over the width of the sliding block 9 and outwards at least by the width of the sliding block 9 plus that for extending the extending screed 4 by half the width of the Basic screed the necessary route protrudes. The sliding block 9 can be moved along the guide 13 by means of a cylinder 14 which acts between the cheek 2 and the sliding block 9. In the exemplary embodiment shown, the guide 13 has two strips 15, which extend parallel to the extension direction of the extension screed 4, with mutually facing lateral guide grooves 16, the guide 13 receiving a guide plate 17 on the underside of the sliding block 9, which is profiled laterally in accordance with the guide grooves 16. The sliding block 9 or its guide plate 17 (or guide strips arranged at a corresponding distance from one another) is sufficiently wide to ensure good guidance when adjusting the sliding block 9.

Der Ausfahrzylinder 3 fährt die Ausfahrbohle 4 gegenüber dem Verschie­bebock 9 um einen vorbestimmten Hub H seitwärts bezüglich des Straßenfertigers aus, wodurch die innere Wange 6 in die Nähe der Innenseite des Verschiebebocks 9 gelangt. Der Verschiebebock 9 - und mit diesem die Ausfahrbohle 4 und der Ausfahrzylinder 3 - wird durch den Zylinder 14 in der Führung 13 seitwärts nach außen geschoben, so daß die Ausfahrbohlen 4 um die halbe Breite der Grundbohle 1 ausgefahren werden können, so daß die Ausfahrbohlen 4 die Grund­bohle 1 in ihrer Breite verdoppeln können. Gegebenenfalls können auch An­ schläge zur Begrenzung des Verschiebeweges des Verschiebebocks (9) vorgesehen sein.The extension cylinder 3 extends the extension screed 4 sideways relative to the paving block 9 with respect to the paver, as a result of which the inner cheek 6 comes close to the inside of the panning block 9. The sliding block 9 - and with this the extending screed 4 and the extending cylinder 3 - is pushed sideways outwards by the cylinder 14 in the guide 13, so that the extending screeds 4 can be extended by half the width of the basic screed 1, so that the extending screeds 4 can double the basic screed 1 in width. If necessary, To Blows to limit the displacement of the trestle (9) may be provided.

Die Achsen des Ausfahrzylinders 3 und der Führungsstange(n) 7 können zweckmäßigerweise zur Erzielung einer größeren Stabilität und Steifigkeit in vertikaler Richtung zueinander versetzt sein.The axes of the extension cylinder 3 and the guide rod (s) 7 can expediently be offset from one another in the vertical direction in order to achieve greater stability and rigidity.

Die Zylinder 3, 14 können eine Folgeschaltung zum aufeinanderfolgenden Auseinander- bzw. Einfahren aufweisen, jedoch kann darauf auch verzichtet werden. Dann fährt der Zylinder mit der geringsten Widerstandsmoment zuerst ein bzw. aus.The cylinders 3, 14 can have a sequential circuit for successive opening and closing, but this can also be dispensed with. Then the cylinder with the lowest section modulus first moves in or out.
