Description
Die Erfindung betrifft einen Deckenfertiger nach dem Oberbegriff
des Anspruchs 1.The invention relates to a paver according to the preamble
of
Beim Bau von zweispurigen Straßen stellt im allgemeinen das Querprofil in geraden Straßenabschnitten ein horizontal liegendes Dachprofil dar. Beginnt jedoch eine Kurve, soll die Lage des Dachprofils kontinuierlich aus der Horizontalen in eine Neigung und das Dachprofil selbst in eine - entsprechend geneigte - Gerade übergehen. Bei Verwendung eines Deckenfertigers mit einer Einbaubohle zum schwimmenden Einbau der entsprechenden Schichten, wobei die Einbaubohle aus zwei quer zur Einbaurichtung gegeneinander verstellbaren Hälften besteht, wird eine möglichst stufenlose Neigungsänderung dadurch erhalten, daß die Verstellung der Bohlenquerneigung und auch die Verstellung des Dachprofils in kleinen Teilverstellungen, die gleichmäßig auf die Übergangsstrecke verteilt werden, möglichst zeitgleich vorgenommen werden.In general, when building two-lane roads Cross profile in straight road sections a horizontally lying roof profile However, if a curve begins, the position of the roof profile should continuously from the horizontal to a slope and the roof profile even transition into a - correspondingly inclined - straight line. Using a paver with a screed for floating paving of the corresponding layers, the screed consisting of two transverse to Installation direction against each other adjustable halves, is a Get the most infinitely variable change in inclination by adjusting the screed bank and also the adjustment of the roof profile in small partial adjustments that are evenly distributed over the transition section be done at the same time as possible.
Die Querneigungsänderung kann bei den Deckenfertigern wie in DE-A-28 38 123 manuell durch entsprechende Höhenverstellung der Bohlenhälften vorgenommen werden. Auch sind Bohlen mit elektronischer Nivellierautomatik bekannt, bei denen die Einstellung der Querneigung der Einbaubohle mittels eines Neigungsreglers vorgenommen wird. - Die Dachprofilneigung wird mittels Schlüssel oder Knarre manuell vorgenommen. - Dementsprechend ist ein gleichzeitiges Variieren von Querneigung und Dachprofilneigung zum Erreichen eines kontinuierlichen Übergangs zwischen gerader Strecke und Kurve problematisch, zumal Ermittlungs- und Einstellfehler bei der Umsetzung des Sollwertes auftreten können, die zu nicht optimal verlegten Schichten im ohnehin für den Verkehr kritischen Kurvenbereichen führen.The change in cross slope can be done manually in the paver finisher as in DE-A-28 38 123 by adjusting the height of the screed halves accordingly. Screeds with electronic automatic leveling are also known which the setting of the transverse slope of the screed by means of a tilt controller is made. - The roof profile slope is determined by Key or ratchet made manually. - Accordingly, is a simultaneous variation of cross slope and roof profile slope to achieve a continuous transition between straight line and Curve problematic, especially as errors in determination and setting during implementation of the setpoint can occur that are not optimally routed Layers in curve areas that are critical for traffic anyway.
Aufgabe der Erfindung ist es, einen Deckenfertiger nach dem
Oberbegriff des Anspruchs 1 zu schaffen, der eine optimale Verstellung
der Bohlenquerneigung und des Dachprofils im Übergangsbereich von einem
geraden Straßenabschnitt in eine Kurve ermöglicht.The object of the invention is to provide a paver after
Preamble of
Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des
Anspruchs 1 dadurch gelöst, daß die Dachprofilneigung über einen elektrischen
oder elektrohydraulischen Antrieb verstellbar und eine Steuerung
mit Eingängen, die mit einem Sensor für die Querneigung und einem
Sensor für die Dachprofilneigung verbunden sind, vorgesehen ist, wobei
die Steuerung die Dachprofilneigung entsprechend dem vorgebenen Wert der

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention are as follows Description and the dependent claims.
In der beigefügten Abbildung ist schematisch eine Einbaubohle dargestellt, die quer zur Einbaurichtung aus zwei Hälften besteht, die gegeneinander verschwenkbar sind, so daß ein Dachprofil mit vorbestimmter Neigung einstellbar ist. In der in der Abbildung dargestellten Ausgangsstellung ist ein Dachprofil mit einer Neigung von 2% nach jeder Seite vorgesehen. Mit einer derartigen Position der Einbaubohle werden die geraden Abschnitte einer Straße oder Fahrbahn eingebaut.In the attached figure, a screed is shown schematically shown, which consists of two halves transverse to the direction of installation are pivotable against each other, so that a roof profile with a predetermined Inclination is adjustable. In the starting position shown in the figure is a roof profile with a slope of 2% after each Page provided. With such a position the screed will be the straight sections of a road or lane are installed.
Außerdem ist die Einbaubohle insgesamt nach rechts oder links zur Erzielung einer bestimmten Querneigung verschwenkbar.In addition, the screed is to the right or left pivotable to achieve a certain bank.
