Description
Die Erfindung betrifft die Herstellung von hohen, zylindrischen oder prismati schen Türmen mit großen Durchmessern, die Aussteifungen enthalten, um sie gegen Wind- oder Erdbebenlasten zu stabilisieren.The invention relates to the production of high, cylindrical or prismatic turrets with large diameters that contain stiffeners around them to stabilize against wind or earthquake loads.
Es ist bekannt, hohe, hohle Türme aus Stahlbeton, deren Querschnitt über die Höhe konstant ist, mittels Gleitschalungen herzustellen, die kontinuierlich ge zogen werden und die Wände fugenlos erstellen. Bei dünnen Schalen werden die Türme innen ausgesteift, um sie gegen Verformung unter Windlast zu sta bilisieren. Die Aussteifungen werden, technologisch bedingt, nachträglich ein gebaut. Dabei entsteht für den im Bau befindlichen freien Wandabschnitt ein labiler Zustand.It is known high, hollow towers made of reinforced concrete, the cross section of which Height is constant, using slipforms that continuously ge be drawn and create the walls seamlessly. With thin shells the inside of the towers is braced to protect them against deformation under wind loads bilize. For technical reasons, the bracing is added subsequently built. This creates a free wall section under construction unstable condition.
Bei hohen Türmen großen Durchmessers besteht weiterhin die Gefahr der Verformung der Gleitschalung durch exzentrische Lasten und Staudruck, wo durch die betonierte Wand von der Sollgeometrie abweicht, die Spannungs verhältnisse sich unkontrollierbar verändern und die Stabilitätsprobleme dra stisch erhöht werden.With tall towers of large diameter there is still the risk of Deformation of the sliding formwork due to eccentric loads and dynamic pressure, where due to the concrete wall deviates from the target geometry, the tension conditions change uncontrollably and the stability problems dra be increased.
Aus der DE-OS 17 09 306 ist es bekannt, Gleitschalungen mittels radial ange ordneter Träger gegen Formänderungen zu stabilisieren.From DE-OS 17 09 306 it is known to provide sliding formwork by means of radially orderly support to stabilize against changes in shape.
Aufgabe der Erfindung ist es, ein sicheres Verfahren zur formtreuen Herstel lung hoher Türme großen Durchmessers zu ermöglichen, bei gleichzeitiger Stabilitätssicherung im Bauzustand und Vereinfachung der Herstellung der bleibenden Aussteifung.The object of the invention is to provide a safe method for form-true manufacture high towers of large diameter, with simultaneous Ensuring stability in the state of construction and simplifying the manufacture of the permanent bracing.
Die Aufgabe wird durch die im Kennzeichen des Verfahrensanspruchs 1 sowie Vorrichtungsanspruchs 6 angegebenen Merkmale gelöst.The object is achieved by the features specified in the characterizing part of method claim 1 and device claim 6 .
Hierzu schlägt die Erfindung vor, die Gleitschalung, die den Umfang des Tur mes umschließt, mit der späteren Aussteifung des Turmes, i. d. R. einem waa gerechten Speichenrad, lösbar zu verbinden. Die somit mitgleitende Ausstei fung sichert damit bis zur endgültigen Verbindung mit der Wand die freie Schale gegen Beulen. Wenn in dem hohen hohlen Turm (Röhre) mehrere Aussteifungen benötigt werden, so sieht eine bevorzugte Ausführungsform der Erfindung vor, alle Aussteifungen übereinander zu legen, und als Paket von der in die Gleitschalung integrierten obersten Aussteifung an zu heben. Nachdem die Gleitschalung die Sollhöhe der unteren Aussteifung plus die Ge samthöhe der dazwischen liegenden Aussteifungsringe passiert hat, wird das Paket gehoben und der untere als erster Aussteifungsring mit der Wand blei bend befestigt. Die mitgenommenen Zwischenringe werden für den nächsten Hub entkoppelt und verbleiben bis die Gleitschalung die nächste Ausstei fungshöhe passiert hat und der Hubvorgang sich wiederholt.To this end, the invention proposes the sliding formwork covering the scope of the door mes encloses, with the later bracing of the tower, i. d. R. a waa just spoke wheel, releasable to connect. The exit that slides along fung ensures free space until the final connection to the wall Bowl against dents. If in the high hollow tower (tube) several Stiffeners are needed, so a preferred embodiment of the Invention before to put all stiffeners on top of each other, and as a package of the uppermost stiffener integrated in the sliding formwork. After the sliding formwork has reached the target height of the lower bracing plus the Ge has passed the entire height of the stiffening rings in between, it will Package lifted and the lower one as the first stiffening ring with the wall lead bend attached. The intermediate rings that have been taken along are used for the next one Stroke decoupled and remain until the slip form the next exit height has passed and the lifting process is repeated.
Die in die Gleischalung integrierte Aussteifung verbleibt als oberste Randaus steifung und kann für einen Umlaufgang, Flugwarnbefeuerung, Blitzschutz u. ä. genutzt werden.The bracing integrated in the track formwork remains as the top edge stiffness and can be used for one round aisle, flight warning lights, lightning protection u. Ä. be used.
Hohe Türme sind aus Projekten für Auswindkraftwerke bekannt. Der durch Temperaturunterschied erzeugte Naturzug treibt Windturbinen zur Stromer zeugung an.High towers are known from projects for wind power plants. The through Differential temperature generated natural train drives wind turbines to the Stromer generation.
Bekannt sind geplante Türme von 200 bis 1000 m Höhe mit Durchmessern von 50 bis 150 m. Die Wandstärken verjüngen sich von ca 100 cm im unteren Bereich auf 18 cm unterhalb der Krone. Die relativ dünne Schale muß gegen Beulen gesichert werden. Die Aussteifung sollte jedoch den Luftstrom nicht behindern. Die bekannten Lösungen sehen daher Druckringe mit radialen Verspannungen vor. Der Druckring wird als geschweißtes Kastenprofil aus Stahlblechen ausgeführt und nach der Befestigung an der Betonwand ausbe toniert. Ähnlich dem Speichenrad beim Fahrrad werden die Speichen nur auf Zug beabsprucht und haben demzufolge bei Ausführung in Stahl einen gerin gen Querschnitt. Diese Bauweise ist aus der DE 196 21 514 A1 bekannt. Die Erfindung beschränkt sich jedoch nicht nur auf die Herstellung von Auf windkraftwerken sondern läßt sich auch zur Herstellung von Hochhäusern und Silos verwenden. Die mit tragender "Lochfassade" als Röhre berechneten Hochhäuser haben aussteifende Deckenscheiben. Diese können von der obersten, ganz oder auch nur als Trägerrost, zur Formgebung als Lehre wie auch zur Aussteifung in die Gleischalung integrierten Deckenkonstruktion pa ketweise gehoben werden. Für die konstruktive Ausbildung kann das be kannte Liftslab-Verfahren mit herangezogen werden. Planned towers with a diameter of 200 to 1000 m are known from 50 to 150 m. The wall thickness tapers from about 100 cm in the lower Area at 18 cm below the crown. The relatively thin shell must be against Bumps are secured. However, the bracing should not block the airflow hinder. The known solutions therefore see pressure rings with radial Tension before. The pressure ring is made as a welded box profile Executed steel sheets and after fixing them to the concrete wall toned. Similar to the spoked wheel on a bicycle, the spokes only open Stressed train and therefore have a clot when executed in steel cross section. This design is known from DE 196 21 514 A1. However, the invention is not limited to the production of on wind power plants but can also be used to manufacture high-rise buildings and Use silos. The one with the bearing "perforated facade" calculated as a tube Skyscrapers have stiffening ceiling panes. These can be from the uppermost, completely or just as a support grate, for shaping as teaching like pa also integrated in the formwork pa for bracing to be lifted in chains. For constructive training, this can be known liftlab method can also be used.
Ein weiteres Anwendungsgebiete ist der Silobau. Hier kann das Tragwerk des Daches in die Gleitschalung integriert werden. Nachher können vom Dach aus die Zwischendecken gehoben werden.Another area of application is silo construction. Here the structure of the Roof can be integrated into the sliding formwork. Afterwards, from the roof the false ceilings are raised.
