Diese Aufgabe wird durch ein Schalungssystem mit den Merkmalen des Anspruches 1 gelöst. Diese Aufgabe wird des Weiteren durch ein Verfahren mit den Merkmalen des Anspruches 15 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der zugeordneten abhängigen Ansprüche. Vorteilhafte Weiterbildungen der Erfindung sind ebenfalls in der Beschreibung und in den Zeichnungen offenbart.This object is achieved by a formwork system with the features of claim 1. This object is further achieved by a method having the features of
Erfindungsgemäß sind an dem Schalungselement und/oder an der Stützanordnung wenigstens zwei Drucksensoren vertikal in unterschiedlichen Positionen angeordnet und mit der Steuerung des Schalungssystems verbunden. Die Drucksensoren sind konzipiert, den aufgrund des in die Schalung eingefüllten Betons auf die Schalungselemente einwirkenden Druck an wenigstens zwei unterschiedlichen Höhen des Schalungselements zu messen. Die Steuerung ist konzipiert, die Betonzuführungen individuell in Abhängigkeit von dem Signal der Drucksensoren zu steuern. Auf diese Weise ist es möglich, den an unterschiedlichen Stellen auf das Schalungselement bzw. vorzugsweise mehrere Schalungselemente einwirkenden Betondruck zu erfassen und die Steuerung kann durch die Drucksensoren gemessenen Druckwerte mit Sollwerten vergleichen und die Betonzuführung individuell so ansteuern, dass der Betondruck an den unterschiedlichen Stellen der Schalungselemente gesetzten Vorgaben entspricht. Auf diese Weise kann eine Betonwand, insbesondere ein Betongewölbe mit vorgegebenen homogenen Materialeigenschaften in dem gesamten Wand- oder Gewölbebereich hergestellt werden.According to the invention, at least two pressure sensors are arranged vertically in different positions on the shuttering element and / or on the support arrangement and connected to the control of the shuttering system. The pressure sensors are designed to measure the pressure acting on the shuttering elements due to the concrete poured into the shuttering at at least two different heights of the shuttering element. The control system is designed to control the concrete infeeds individually depending on the signal from the pressure sensors. In this way it is possible to detect the concrete pressure acting at different points on the formwork element or preferably a plurality of formwork elements and the control can compare pressure values measured with nominal values by the pressure sensors and individually control the concrete feed so that the concrete pressure at the different points of the concrete Shuttering elements set specifications. In this way, a concrete wall, in particular a concrete vault with predetermined homogeneous material properties in the entire wall or vault area can be produced.
In einer vorteilhaften Weiterbildung der Erfindung hat die Stützanordnung wenigstens einen hydraulischen Stützträger zur Abstützung des Schalungselements und die Steuerung ist konzipiert, die Kraft des Stützträgers in Abhängigkeit von dem in den Drucksensoren gemessenen Druck zu steuern. Der Druck kann somit nicht nur über die individuelle Betonzuführung, sondern auch über den Abstützdruck mittels der Stützträger einreguliert werden. Zudem müssen die Drucksensoren nicht in der Schalung selbst vorgesehen sein, sondern können an den Kraftaufnahmeelementen der Schalungselemente angeordnet sein, z.B. an den Punkten, an denen die Trägerstruktur statisch das Schalungselement abstützt. Insbesondere, wenn die gesamte Schalung aus mehreren Schalungselementen besteht, wie das beim Tunnelbau üblich ist, ist man so in der Lage über die Abstützpunkte der Schalungselemente den auf die einzelnen Schalungselemente einwirkenden Druck genau zu erfassen und die Betonzuführungen und/oder die Abstützkraft der hydraulischen Stützträgern entsprechend zu steuern bzw. zu regulieren.In an advantageous development of the invention, the support arrangement has at least one hydraulic support carrier for supporting the formwork element and the control is designed to control the force of the support carrier in dependence on the pressure measured in the pressure sensors. The pressure can thus be regulated not only on the individual concrete supply, but also on the Abstützdruck means of the support beams. In addition, the pressure sensors need not be provided in the formwork itself, but may be disposed on the force receiving elements of the formwork elements, e.g. at the points where the support structure statically supports the formwork element. In particular, if the entire formwork consists of several formwork elements, as is customary in tunneling, one is able to accurately detect the pressure acting on the individual formwork elements pressure on the support points of the formwork elements and the concrete feeders and / or the supporting force of the hydraulic support beams to control or regulate accordingly.
In einer technisch einfachen Ausführungsform ist der Drucksensor an dem Verbindungspunkt zwischen dem Stützträgern und dem Schalungselement und/oder der Stützanordnung angeordnet. Eine derartige Anordnung ist leicht zu realisieren, z.B. durch an sich bekannte Kraftaufnehmer.In a technically simple embodiment, the pressure sensor is arranged at the connection point between the support beams and the formwork element and / or the support arrangement. Such an arrangement is easy to implement, e.g. by per se known force transducer.
Vorzugsweise sind mehrere, insbesondere eine Vielzahl von Drucksensoren flächig verteilt über das Schalungselement angeordnet. Vorzugsweise sind die Drucksensoren gleichmäßig über die gesamte Fläche der Wand und damit über die Fläche der Schalungselemente angeordnet, wenn mehrere verwendet werden. Auf diese Weise kann eine sehr gute Druckverteilung des Betons auf die Schalung erfasst und evtl. nachreguliert werden.Preferably, several, in particular a plurality of pressure sensors distributed over the formwork element arranged. Preferably, the pressure sensors are arranged uniformly over the entire surface of the wall and thus over the surface of the formwork elements, if several are used. In this way, a very good pressure distribution of the concrete on the formwork can be detected and possibly readjusted.
Vorzugsweise enthält das Schalungssystem wenigstens eine Rütteleinrichtung und die Steuerung ist konzipiert, die Rütteleinrichtung in Abhängigkeit von dem in den Drucksensoren gemessenen Druck zu steuern. Auf diese Weise kann in Bereichen, in welchen der auf die Schalung einwirkende Betondruck zu niedrig ist, durch nachrüttelt des Betons in den Bereichen erzielt werden, dass der Betondruck zunimmt. Die Rütteleinrichtung kann z.B. in Verbindung mit den Schalungselementen angeordnet sein. Es können jedoch auch Außenrüttler in Verbindung mit den Betonzuführungen vorgesehen werden, die Einfluss auf die Viskosität des zugeführten Betons nehmen.Preferably, the formwork system includes at least one vibrator, and the controller is designed to control the vibrator as a function of the pressure measured in the pressure sensors. In this way, in areas where the concrete pressure acting on the formwork is too low, shake-ups of the concrete in the areas can be achieved so that the concrete pressure increases. The vibrating device can be arranged, for example, in connection with the formwork elements. However, external vibrators can also be provided in connection with the concrete feeders, which influence the viscosity of the supplied concrete.
Vorzugsweise sind mehrere Rütteleinrichtungen an unterschiedlichen Stellen des Schalungselements angeordnet und die Steuerung ist konzipiert, die Rütteleinrichtung individuell in Abhängigkeit von den Signalen der Drucksensoren zu steuern. Auf diese Weise kann ein vorgegebenes Druckprofil des Betons auf die Schalungselemente erreicht werden, das zu gewünschten homogenen Festigkeitseigenschaften der erstellten Betonwand über die Fläche führt. Vorzugsweise sind die Rütteleinrichtungen flächig gleichmäßig über die Schalungselemente verteilt angeordnet. Auf diese Weise kann über die Fläche der Schalung eine gleichmäßige Verdichtung erzielt werden.Preferably, a plurality of vibrators are arranged at different locations of the formwork element and the controller is designed to control the vibrator individually as a function of the signals of the pressure sensors. In this way, a predetermined pressure profile of the concrete can be achieved on the formwork elements, which leads to desired homogeneous strength properties of the created concrete wall over the surface. Preferably, the vibrators are arranged evenly distributed over the formwork elements. In this way, a uniform compression can be achieved over the surface of the formwork.
In einer vorteilhaften Weiterbildung der Erfindung ist die Steuerung konzipiert, die Betonpumpe in Abhängigkeit von den Signalen der Drucksensoren zu steuern. So können z.B. für unterschiedliche Betonzuführungen unterschiedliche Betonpumpen vorgesehen sein und über den Förderdruck der Betonpumpe kann Einfluss genommen werden auf den Druck, den der Beton auf das Schalungselement ausübt.In an advantageous embodiment of the invention, the controller is designed to control the concrete pump in response to the signals of the pressure sensors. Thus, e.g. Different concrete pumps can be provided for different concrete feeds and the delivery pressure of the concrete pump can be influenced by the pressure exerted by the concrete on the formwork element.
Vorzugsweise ist die wenigstens eine Betonpumpe über wenigstens eine Verteilereinrichtung mit mehreren Betonzuführungen verbunden. Die Steuerung ist in diesem Fall dazu konzipiert, die Verteilereinrichtung in Abhängigkeit von den Signalen der Drucksensoren zu steuern, um auf diese Weise ein homogenes, vorgegebenes Druckprofil und damit gewünschte Materialeigenschaften der erstellten Betonwand zu erzielen.Preferably, the at least one concrete pump is connected via at least one distributor device with a plurality of concrete feeders. In this case, the controller is designed to control the distributor device as a function of the signals from the pressure sensors in order to achieve a homogeneous, predetermined pressure profile and thus desired material properties of the concrete wall created.
Vorzugsweise weist die Steuerung einen Bildschirm zur Darstellung der Schalungselemente und der dort gemessenen Druckwerte auf. Auf diese Weise kann ein Operator sehen, welche Druckwerte an unterschiedlichen Teilen der Schalungselemente aufgenommen wurden und kann sogleich erfassen, ob der Beton in vorgegebener Weise dem Raum hinter den Schalungselementen zugeführt worden ist. Dies ist z.B. bei der Erstellung eines Tunnelgewölbes äußerst wichtig, da sichergestellt werden muss, dass der Beton an allen Stellen jenseits der Schalungselemente durchgängig den Zwischenraum zwischen einer Tunnelwand und den Schalungselementen ausfüllt und damit in der Lage ist, den geforderten Festigkeitseigenschaften des Tunnelgewölbes zu genügen.Preferably, the controller has a screen for displaying the formwork elements and the pressure values measured there. In this way, an operator can see which pressure values have been recorded on different parts of the formwork elements and can immediately detect whether the concrete has been supplied in a predetermined manner to the space behind the formwork elements. This is e.g. In the construction of a tunnel vault is extremely important because it must be ensured that the concrete at all points beyond the formwork elements consistently fills the gap between a tunnel wall and the formwork elements and thus is able to meet the required strength properties of the tunnel arch.
In einer vorteilhaften Weiterbildung des erfindungsgemäßen Schalungssystems hat dieses zumindest vier Schalungselemente, die durch wenigstens vier Stützträger gegen die Stützanordnung abgestützt sind. Eine derartige Anordnung ist somit für ein Tunnelgewölbe sinnvoll, wobei die vier Schalungselemente mehr oder weniger den oberen Halbkreis des Tunnelgewölbes bilden. Vorzugsweise sind hierfür die vier Schalungselemente gewölbt und bilden eine Gewölbefläche für ein Tunnelgewölbe.In an advantageous development of the formwork system according to the invention this has at least four formwork elements, which are supported by at least four support beams against the support assembly. Such an arrangement is thus useful for a tunnel vault, the four formwork elements more or less the form the upper semicircle of the tunnel arch. Preferably, the four formwork elements are curved for this purpose and form a vaulted area for a tunnel arch.
Da eine Tunnelschalung in der Regel sehr lang ist, hat das erfindungsgemäße Schalungssystem vorzugsweise mehrere horizontal hintereinander angeordnete Stützanordnungen mit eigenen Schalungselementen. Die Steuerung ist dann konzipiert, die Druckbeaufschlagung der Schalungselemente der einzelnen Stützanordnungen individuell in Abhängigkeit von den Druckwerten der Drucksensoren zu steuern. Auf diese Weise kann eine homogene Tunnelschalung über eine größere Länge in einem Vorgang hergestellt werden, wobei über die Fläche eine sehr gute Homogenität der Betonwand erzielt wird.Since a tunnel formwork is usually very long, the formwork system according to the invention preferably has a plurality of horizontally arranged one behind the other support arrangements with their own formwork elements. The controller is then designed to control the pressurization of the formwork elements of the individual support arrangements individually as a function of the pressure values of the pressure sensors. In this way, a homogeneous tunnel formwork over a greater length can be produced in one operation, over the area a very good homogeneity of the concrete wall is achieved.
In einem erfindungsgemäßen Verfahren, das das erfindungsgemäße Schalungssystem nutzt, wird eine Betonwand errichtet, in der mittels Drucksensoren der auf das Schalungselement wirkende Druck an unterschiedlichen Stellen ermittelt wird und die wenigstens eine Betonpumpe und/oder die Betonzuführung in Abhängigkeit von den Signalen der Drucksensoren gesteuert wird bzw. werden. Auf diese Weise kann durch die individuelle Steuerung der Betonzuführung bzw. der Betonpumpe(n) dafür Sorge getragen werden, dass ein gleichmäßiges Druckprofil oder ein vorgegebenes Druckprofil über die Fläche der Schalungselemente erzielt wird, was Tunnelgewölbe mit geforderten Festigkeitseigenschaften mit sich bringt.In a method according to the invention which uses the formwork system according to the invention, a concrete wall is constructed in which the pressure acting on the formwork element pressure is determined at different locations by means of pressure sensors and the at least one concrete pump and / or the concrete feed is controlled in response to the signals of the pressure sensors or be. In this way, care can be taken by the individual control of the concrete feed or the concrete pump (s) that a uniform pressure profile or a predetermined pressure profile over the surface of the formwork elements is achieved, which brings tunnel vault with required strength properties with it.
Durch die Signale der Drucksensoren lassen sich auch Rütteleinrichtungen bzw. Verteilereinrichtungen zwischen den Betonzuführungen ansteuern, um so die Betonzuführung zu den individuellen Stellen zwischen einer Tunnelwand und den Schalungselementen möglichst gleichmäßig und homogen zu füllen.By the signals of the pressure sensors and vibrators or distribution devices can be controlled between the concrete feeders so as to fill the concrete supply to the individual points between a tunnel wall and the formwork elements as evenly and homogeneously.
Neben den Signalen der Drucksensoren können auch die Signale anderer Sensoren wie z.B. Temperatursensoren, optischer Sensoren oder chemischer Sensoren für die Steuerung der Stützanordnung, der individuellen Betonzuführungen und der Rütteleinrichtungen verwendet werden.In addition to the signals of the pressure sensors, the signals of other sensors such as e.g. Temperature sensors, optical sensors or chemical sensors for the control of the support assembly, the individual concrete feeders and the vibrators are used.
Durch die Erfindung können somit die Eigenschaften des in die Schalung eingefüllten Betons festgestellt, ausgewertet und für die Steuerung der Betonzuführungen, Stützanordnung und Rütteleinrichtungen genutzt werden. Zur besseren Bedienung hat die Steuerung vorzugsweise einen Bildschirm, der das Schalungssystem flächig darstellt, als auch eine Betonfüllanzeige für die unterschiedlichen Bereiche der Schalungselemente. Die gemessenen Kräfte werden vorzugsweise über eine Software ausgewertet und digital sowie visuell angezeigt. Vorzugsweise hat die Steuerung eine Schnittstelle zur Ansteuerung weiterer Komponenten, wie z.B. eine Rütteleinrichtung, als auch zum Aufspielen der Daten auf externe Datenträger bzw. auf einen zusätzlichen PC. Aufgrund der erfassten Signale der Drucksensoren kann die Verdichtungssteuerung jenseits der Schalungselemente automatisch erfolgen.By means of the invention, the properties of the concrete filled into the formwork can thus be ascertained, evaluated and utilized for the control of the concrete feeders, support arrangement and vibrating devices. For better operation, the controller preferably has a screen, which represents the formwork system area, as well as a Betonfüllanzeige for the different areas of the formwork elements. The measured forces are preferably via software evaluated and displayed digitally and visually. Preferably, the controller has an interface for controlling other components, such as a vibrator, as well as for loading the data on external media or on an additional PC. Due to the detected signals of the pressure sensors, the compression control can take place automatically beyond the formwork elements.
Man hat durch die Erfindung eine Gegenkontrolle zur statischen Berechnung des Schalungsprozesses. Die Sicherheit für das Schalungssystem als auch für die Personen, die das Schalungssystem bedienen wird beträchtlich erhöht. Es werden homogenere und bessere Tunnelwände erzielt, wodurch die Abläufe beim Betonieren optimiert werden. Durch die Erfindung wird die Erstellung von Normen konformen Betonwänden und Gewölben erreicht. Die Ausgänge der Steuerung können auch für Sicherheitssysteme genutzt werden, wenn Spannungsüberhöhung oder Drucküberhöhungen an einzelnen Stellen der Schalungselemente erfasst werden sollten. Die Erfindung trägt zur Qualitätssicherung des Bauwerks bei.By means of the invention, a counter-check is made to the static calculation of the shuttering process. The safety for the formwork system as well as for the persons who operate the formwork system is considerably increased. Homogeneous and better tunnel walls are achieved, which optimizes concreting processes. The invention achieves the creation of standards compliant concrete walls and vaults. The outputs of the controller can also be used for safety systems, if voltage overshoots or pressure peaks at individual points of the formwork elements should be detected. The invention contributes to the quality assurance of the building.
Ein wesentlicher Aspekt der Erfindung besteht darin, dass über die gezielte Steuerung der Betonpumpe und/oder der Betonzuführung und/oder der wenigstens einen Rütteleinrichtung die Verdichtungsprozesse des Betons jenseits der Schalungselemente gezielt und individuell gesteuert werden können, um somit gewünschte Materialeigenschaften der fertigen Betonwand bzw. des fertigen Betongewölbes zu erzielen.An essential aspect of the invention is that on the targeted control of the concrete pump and / or the concrete supply and / or the at least one vibrating the compression processes of the concrete beyond the formwork elements can be controlled specifically and individually, thus desired material properties of the finished concrete wall or achieve the finished concrete vault.
Es ist für den Fachmann offensichtlich, dass die einzelnen Komponenten der Erfindung einfach oder mehrfach vorgesehen werden können bzw. diese können auch als integrierte Einheit oder verteilt an mehreren Stellen ausgebildet sein. Die Steuerung kann mehrere Rechner umfassen, die über die Länge des Tunnels verteilt sind. Ebenso weist üblicherweise ein Tunnelschalungssystem eine Vielzahl von Schalungselementen auf, z.B. vier Schalungselemente über dem Gewölbesektor verteilt und drei bis sechs Stützanordnungen hintereinander mit jeweils vier Schalungselementen, so dass insgesamt die Anlage vorzugsweise zwischen zehn und fünfzig Schalungselemente aufweist.It is obvious to a person skilled in the art that the individual components of the invention can be provided simply or multiply, or they can also be designed as an integrated unit or distributed at several locations. The controller may include multiple computers distributed throughout the length of the tunnel. Similarly, a tunnel formwork system usually has a plurality of formwork elements, e.g. four formwork elements distributed over the vault sector and three to six support assemblies in a row, each with four formwork elements, so that in total the system preferably has between ten and fifty formwork elements.
