Die FR 2 958 873 A1 offenbart eine transportable Schalungsvorrichtung zur Herstellung von Beton-Fertigteilen mit einer Mittelschalung auf einem auf den Boden abstellbaren Grundgerüst und einer Außenschalung, die auf quer verlaufenden Schienen auf dem Grundgerüst verfahrbar ist.The FR 2 958 873 A1 discloses a transportable formwork device for the production of precast concrete parts with a central formwork on a floor-levelable skeleton and an outer formwork, which is movable on transverse rails on the skeleton.

Eine Schalungsvorrichtung, gemäß dem Oberbegriff des Anspruchs 1, wird in der DE 10 2007 019 383 A1 beschrieben, die auf einem Grundträger eine Innenschalung und eine Außenschalung aufweist, wobei die Innenschalung auf einem Rollensystem auf dem Grundträger gelagert und relativ zur Außenschalung verschoben werden kann. Der Erfindung liegt die Aufgabe zugrunde, mit einfachen Maßnahmen eine flexibel einsetzbare Schalungsvorrichtung zur Herstellung von Beton-Fertigteilen zu schaffen.A formwork device according to the preamble of claim 1, is in the DE 10 2007 019 383 A1 described, which has an inner formwork and an outer formwork on a base support, wherein the inner formwork can be mounted on a roller system on the base support and moved relative to the outer formwork. The invention has for its object to provide with simple measures a flexible formwork device for the production of precast concrete parts.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This object is achieved with the features of claim 1. The dependent claims indicate expedient developments.

Die erfindungsgemäße Schalungsvorrichtung zur Herstellung von Beton-Fertigteilen ist transportabel ausgeführt und weist mindestens eine vertikale Mittelschalung auf, die fest auf einem fahrbaren Auflieger angeordnet ist. Des Weiteren umfasst die Schalungsvorrichtung mindestens eine vertikale Außenschalung, die auf Schienen auf einer verstellbaren Arbeitsplattform verfahrbar ist, wobei die Arbeitsplattform in montierter Position an den Auflieger angrenzt und ggf. mit diesem verbunden ist, welcher Träger der Mittelschalung ist. Die Arbeitsplattform ist separat vom Auflieger ausgebildet. Die Schalungen stehen vertikal und begrenzen dementsprechend einen vertikalen Aufnahmeraum zur Aufnahme von Beton.The formwork device according to the invention for the production of precast concrete parts is designed to be transportable and has at least one vertical middle formwork, which is fixedly mounted on a mobile semi-trailer. Furthermore, the formwork device comprises at least one vertical outer formwork, which can be moved on rails on an adjustable work platform, wherein the work platform in the mounted position adjacent to the trailer and possibly connected to this, which is carrier of the central formwork. The working platform is designed separately from the semi-trailer. The formwork is vertical and accordingly limits a vertical receiving space for receiving concrete.

Die vertikalen Schalungen bilden Schalwände bzw. -tafeln und begrenzen in Querrichtung den zwischenliegenden Beton-Aufnahmeraum, welcher zusätzlich am Boden von einer horizontalen Bodenschalung und an den beiden Stirnseiten von jeweils einer Stirnschalung begrenzt ist. Die Bodenschalung und die Stirnschalungen hängen an einer vertikalen Schalung und können in der Höhe (Bodenschalung) bzw. in Längsrichtung (Stirnschalungen) zur Einstellung der Größe des Beton-Aufnahmeraums verstellt werden.The vertical formwork forms formwork panels or panels and bounds in the transverse direction the intermediate concrete receiving space, which is additionally delimited at the bottom by a horizontal bottom formwork and at the two end faces of one end formwork each. The bottom formwork and the front formwork hang on a vertical formwork and can be adjusted in height (bottom formwork) or in the longitudinal direction (end formwork) to adjust the size of the concrete receiving space.

Die Schalungsvorrichtung ist vollständig transportabel ausgebildet und kann in Einzelteilen zum Einsatzort transportiert werden. Die Transportfähigkeit wird zum einen durch die Mittelschalung auf dem fahrbaren Auflieger gewährleistet und zum andern durch die separate Ausführung der Arbeitsplattform, welche Träger der Schienen ist, auf denen die Außenschalung verfahrbar ist. Aus den Einzelbestandteilen kann die Schalungsvorrichtung vor Ort zusammengesetzt werden, so dass man mit geringem Aufwand an beliebigen Einsatzorten in kurzer Zeit eine Schalungsvorrichtung zur Erzeugung von Beton-Fertigteilen aufstellen kann. Die Transportfähigkeit ist hierbei trotz des hohen Gewichtes der Schalungen gewährleistet. Die Mittelschalung ist fest auf dem Auflieger angeordnet und wird gemeinsam mit diesem transportiert. Gegebenenfalls können auf dem Auflieger zusätzlich eine oder mehrere weitere Schalungen transportiert werden, welche im montierten Zustand als verfahrbare Schalung auf der Arbeitsplattform angeordnet sind. Die Arbeitsplattform mit den darauf angeordneten Schienen für die Verfahrbarkeit der Schalungen kann ihrerseits aus Einzelbestandteilen zusammengesetzt werden, die in einfacher Weise transportiert werden können. Möglich ist es aber auch, die Arbeitsplattform als Ganzes transportabel auszubilden, beispielsweise dadurch, dass auch die Arbeitsplattform als fahrbarer Auflieger ausgeführt ist.The formwork device is designed to be completely transportable and can be transported in parts to the place of use. The transportability is ensured on the one hand by the middle formwork on the mobile semi-trailer and on the other hand by the separate execution of the working platform, which is the carrier of the rails on which the outer formwork is movable. From the individual components, the formwork device can be assembled on site, so that you can set up a formwork device for the production of precast concrete parts with little effort at any location in a short time. The transportability is ensured here despite the high weight of the formwork. The middle formwork is fixed on the trailer and transported together with it. Optionally, one or more further formworks can additionally be transported on the semi-trailer, which are arranged in the assembled state as movable formwork on the work platform. The work platform with the rails arranged thereon for the movability of the formwork can in turn be composed of individual components which can be transported in a simple manner. But it is also possible to make the work platform as a whole portable, for example, the fact that the work platform is designed as a mobile semi-trailer.

Die Arbeitsplattform kann verstellbar ausgebildet sein, insbesondere höheneinstellbar, um am Aufstellungsort Höhenunterschiede zum Auflieger ausgleichen zu können und insbesondere die Schienen in eine horizontale Position sowie in eine vorbestimmte Höhe zum Auflieger zu bringen. Die Einstellbarkeit in der Höhe wird über eine Höheneinstelleinrichtung gewährleistet, welche beispielsweise als eine Mehrzahl von in der Höhe einstellbaren Füßen an der Unterseite der Arbeitsplattform ausgeführt ist.The work platform can be designed to be adjustable, in particular adjustable in height, in order to be able to compensate differences in height to the trailer at the site and in particular to bring the rails in a horizontal position and in a predetermined height to the trailer. The adjustability in height is ensured by a height adjustment, which is designed for example as a plurality of adjustable height feet on the underside of the work platform.

Gemäß einer zweckmäßigen Ausführung sind zu beiden Seiten des die Mittelschalung tragenden Aufliegers Arbeitsplattformen andockbar, die jeweils Schienen aufweisen, auf denen mindestens eine Schalung verfahrbar ist. Dies ermöglicht es, beide Seiten der Mittelschalung für die Herstellung von Beton-Fertigteilen zu nutzen. Hierbei kann es zweckmäßig sein, auf dem Auflieger zwei parallel angeordnete Mittelschalungen vorzusehen, die jeweils einer Schalung auf der links und rechts angedockten Arbeitsplattform zugeordnet sind.According to an expedient embodiment, working platforms can be docked on both sides of the semi-formwork-bearing semitrailer, each having rails on which at least one formwork can be moved. This makes it possible to use both sides of the middle formwork for the production of precast concrete parts. It may be expedient to provide on the trailer two parallel arranged central formwork, each associated with a formwork on the left and right docked work platform.

In den Auflieger können quer zur Mittelschalung Schienenabschnitte integriert sein, die sich bis zum seitlichen Rand des Aufliegers erstrecken und in der montierten Position mit den Schienen in der Arbeitsplattform fluchten. Der Schienenweg erstreckt sich in dieser Ausführung somit nicht nur entlang der Arbeitsplattform, sondern zusätzlich auch noch im Seitenbereich des Aufliegers bis in die Nähe der Mittelschalung, so dass die auf der Arbeitsplattform verfahrbare Schalung bis auf den Auflieger verstellt werden kann. Dies ermöglicht es, auch verhältnismäßig dünnwandige Beton-Fertigteile herzustellen.In the semitrailer rail sections can be integrated, which extend to the lateral edge of the trailer and aligned in the mounted position with the rails in the working platform. The rail extends in this embodiment not only along the working platform, but also in the side area of the trailer to near the middle formwork, so that the movable on the working platform formwork can be adjusted to the semi-trailer. This makes it possible to produce relatively thin-walled precast concrete parts.

Auf der Arbeitsplattform können gegebenenfalls mehrere Schalungen angeordnet sein, von denen die dem Auflieger abgewandte Schalung eine Außenschalung bildet und die zwischen der Außenschalung und der Arbeitsplattform angeordnete Schalung eine Zwischenschalung. Gegebenenfalls sind mehrere Zwischenschalungen vorgesehen, wobei jeweils zwischen zwei benachbarten Schalungen Betonaufnahmeräume für die Herstellung von Beton-Fertigteilen gebildet sind. Sämtliche Schalungen auf der Arbeitsplattform sind auf den Schienen verfahrbar.On the work platform may optionally be arranged a plurality of formwork, of which the semitrailer facing away form an outer formwork and arranged between the outer formwork and the work platform formwork an intermediate formwork. Optionally, a plurality of intermediate formworks are provided, wherein in each case between two adjacent formworks concrete receiving spaces for the production of precast concrete parts are formed. All formwork on the work platform can be moved on the rails.

Der Auflieger kann, gemäß einer weiteren zweckmäßigen Ausführung, Träger eines Hydraulikaggregats sein, der mindestens einen Hydraulikzylinder beaufschlagt, welcher mit einer Schalung auf der Arbeitsplattform koppelbar ist. Über den Hydraulikzylinder kann die Schale auf der Arbeitsplattform mit einer Zugkraft in Richtung des Aufliegers beaufschlagt werden. Hierdurch wird ein Gegendruck erzeugt, welcher dem von dem eingefüllten Beton ausgeübten Druck entgegenwirkt und die Schalungen in Position hält. Über den Hydraulikzylinder wird insbesondere die Außenschalung gehalten, wobei die Zwischenschalungen aufgrund ihrer Position zwischen der Mittelschalung und der Außenschalung ebenfalls mit einer Haltekraft beaufschlagt werden. Der Hydraulikzylinder kann unmittelbar an der Mittelschalung oder über eine Haltevorrichtung unmittelbar auf dem Auflieger befestigt sein.The semi-trailer may, according to a further expedient embodiment, be carriers of a hydraulic unit which acts on at least one hydraulic cylinder, which can be coupled to a formwork on the working platform. About the hydraulic cylinder, the shell can be acted upon on the work platform with a pulling force in the direction of the trailer. As a result, a back pressure is generated, which counteracts the pressure exerted by the filled concrete pressure and holds the formwork in position. In particular, the outer formwork is held via the hydraulic cylinder, wherein the intermediate formworks are also subjected to a holding force due to their position between the middle formwork and the outer formwork. The hydraulic cylinder can be fastened directly to the middle formwork or via a holding device directly on the semitrailer.

Gemäß einer weiteren zweckmäßigen Ausführung ist in mindestens eine Schalung eine Heizeinrichtung integriert. Die Heizeinrichtung kann in die Mittelschalung und/oder in eine oder mehrere Schalungen auf der Arbeitsplattform integriert sein. Die Heizeinrichtung ermöglicht, bei einer entsprechenden Temperatur des Heizmediums, welches durch die Schalung geführt wird, gegebenenfalls auch ein Kühlen, so dass sowohl ein Einsatz an Orten mit tiefer Temperatur als auch an Orten mit hoher Temperatur möglich ist.According to a further expedient embodiment, a heating device is integrated in at least one formwork. The heating device can be integrated in the middle formwork and / or in one or more formworks on the work platform. The heater allows, at a corresponding temperature of the heating medium, which is passed through the formwork, optionally also a cooling, so that both a use in places with low temperature and in places with high temperature is possible.

Des Weiteren kann es zweckmäßig sein, zumindest in eine Schalung auf dem Auflieger eine Vibrationseinrichtung (Rüttler) zu integrieren, um eine Verdichtung des eingefüllten Betons zu erreichen.Furthermore, it may be expedient, at least in a formwork on the trailer to integrate a vibration device (vibrator) to achieve a compression of the filled concrete.

Zumindest eine Schalung auf der Arbeitsplattform, vorteilhafterweise die Außenschalung, kann elektromotorisch angetrieben sein, so dass die Verstellbewegung der Schalung auf den Schienen der Arbeitsplattform mithilfe eines Elektromotors möglich ist. Gegebenenfalls ist auch eine oder sind mehrere Zwischenschalungen auf der Arbeitsplattform elektromotorisch antreibbar. Grundsätzlich möglich ist aber auch eine Verstellbewegung der Außenschalung und/oder der Zwischenschalung auf der Arbeitsplattform auf den Schienen ohne Elektromotor.At least one formwork on the work platform, advantageously the outer formwork, can be driven by an electric motor, so that the adjustment movement of the formwork on the rails of the work platform by means of an electric motor is possible. Optionally, one or more intermediate formwork on the work platform can be driven by an electric motor. In principle, however, is also an adjustment of the outer formwork and / or the intermediate formwork on the work platform on the rails without electric motor.

Gemäß einer weiteren zweckmäßigen Ausführung weist die Schalungsvorrichtung ein Hebezeug auf, beispielsweise einen Portalkran, über den insbesondere eine Betonverfüllvorrichtung bewegbar ist, beispielsweise ein Betonierkübel oder ein Betonverteiler. Das Hebezeug ist bevorzugt ebenso wie die Arbeitsplattform separat vom Auflieger und auch separat von der Arbeitsplattform ausgebildet und wird vor Ort an der Schalungsvorrichtung montiert bzw. zu dieser verfahren. Dies erlaubt einen separaten Transport des Hebezeugs.
