Abstract
Auf die beschädigte Bewehrung wird unter Zwischenschaltung einer ausgleichenden Mörtelschicht ein vorgefertigter, mehrteiliger Spannring mittels eines oder mehrerer innerhalb seines Querschnitts in Spannkanälen angeordneter Spannglieder mit nachträglichem Verbund aufgespannt. Der Spannring kann in den dabei offen bleibenden Fugen zwischen seinen Ringabschnitten in Umfangsrichtung keine Druckkräfte aufnehmen, so daß die Kraft der Spannglieder voll in die Behälterwand eingeleitet wird. Nach dem Spannen werden erst die Spannkanäle verpreßt, bevor die Stoßfugen zwischen den Ringabschnitten verfüllt werden.A prefabricated, multi-part clamping ring is stretched onto the damaged reinforcement with the interposition of a leveling layer of mortar by means of one or more tendons with a subsequent bond that are arranged in clamping channels within its cross-section. The clamping ring cannot absorb any compressive forces in the circumferential direction in the joints that remain open between its ring sections, so that the force of the clamping members is fully introduced into the container wall. After clamping, the clamping channels are first pressed before the butt joints between the ring sections are filled.
Description
Die Erfindung betrifft ein Verfahren zur Sanierung von runden Behältern zur Lagerung von Flüssigkeiten od. dgl., deren durch Umwickeln hergestellte Spannbewehrung beschädigt ist, wobei an der Außenfläche der Behälterwand neue ringförmige Spannglieder angebracht werden. Die Erfindung bezieht sich außerdem auf eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for the rehabilitation of round containers for storing liquids Od. The like. The tensioned reinforcement produced by wrapping is damaged, with the outer surface of the New annular tendons are attached to the container wall. The invention also relates to a device for carrying out the method.
Bei einem Verfahren der gattungsgemäßen Art (vgl. die Zeitschrift »Bauplanung-Bautechnik«, 1968, Heft 4, Seite 186 bis 189) werden als Spannglicdcr horizontale Kabelringe verwendet, die jeweils aus drei Abschnitten bestehen, von denen jeder über ein Drittel des Behälterumfanges verläuft Die in Abständen von 500 mm mit Rundeisen 12 mm 0 unterlegten Kabelringe liegen nach dem Spannen ungeschützt frei. Sie werden dann mit einem in mehreren Schichten aufgetragenen, 40 mm starken Torkretputz geschützt.In a method of the generic type (cf. the magazine "Bauplanung-Bautechnik", 1968, issue 4, Pages 186 to 189) are used as tension members for horizontal cable rings, each made up of three sections exist, each of which runs over a third of the circumference of the container at intervals of 500 mm with Round iron 12 mm 0 underlaid cable rings are exposed unprotected after tensioning. You will then Protected with a 40 mm thick Torkret plaster applied in several layers.
Der den Behälter als starre Schale umfassende Schuizputzauftrag unterliegt ständig wechselnden BeIastungen durch das Füllen und Entleeren des Behälters sowie durch die Witterung und Sonneneinstrahlung. Das kann zu Rißbildung und zum Abplatzen des Torkretputzes führen. Dort eindringendes Wasser bewirkt wiederum ein Korrodieren der Spannglieder und damit deren Versagen bis zum Bruch.The protective plaster application encompassing the container as a rigid shell is subject to constantly changing loads by filling and emptying the container as well as by the weather and solar radiation. This can lead to the formation of cracks and the peeling of the Torkret plaster. Water penetrates there again corroding of the tendons and thus their failure to the point of rupture.
Es ist die Aufgabe der Erfindung, ein Verfahren bzw. eine Vorrichtung zu schaffen, mit dem bzw. der die beschädigte, umwickelte Spannbewehrung derart ergänzt werden kann, daß danach der Behälter wieder dauerhaft voll gebrauchsfähig ist.It is the object of the invention to provide a method and a device with which the damaged, wrapped prestressed reinforcement can be supplemented in such a way that the container is then permanently again is fully usable.
Die Lösung dieser Aufgabe wird in verfahrensmäßiger Hinsicht mit den im kennzeichnenden Teil des Hauptanspruchs aufgezeigten Maßnahmen gelöst. Vorrichtungsmäßig werden zur Durchführung des Verfahrens die im Kennzeichen des Anspruchs 3 aufgeführten Merkmale vorgeschlagen. Vorteilhafte Ausgestaltungen derErfindungsindGegenstandder Ansprüche 2.4und5.The solution to this problem is procedurally with the in the characterizing part of Main claim identified measures resolved. The device is used to carry out the process the features listed in the characterizing part of claim 3 proposed. Advantageous configurations the invention is the subject of claims 2.4 and 5.
Die erfindungsgemäße Lösung der Aufgabe erbringt den Vorteil, daß als Ersatz für die an der Behälterwand verbleibende, aber infolge Korrosion oder Brand ausgefallene umwickelte Spannbewehrung mit jedem der aus mehreren Ringabschnitten bestehenden Fertigteilringe und der zugehörigen Spannglieder eine neue, den Behälter umspannende Ringkraft aufgebracht werden kann. Dabei werden die einzelnen Ringabschnitte in Umfangsrichtung nicht auf Druck belastet. Die erfindungsgemäß innerhalb von Spannkanälen in den mehrleiligen Fertigteilringen verlegten und mit Auspreßmörtel umgebenen Spannglieder sind dort gegen Korrosion, mechanische Angriffe und den direkten Angriff von offenem Feuer geschützt. Nachstehend ist die Erfindung anhand der Zeichnung beispielhaft näher erläutert. Es zeigtThe inventive solution to the problem has the advantage that as a replacement for the on the container wall remaining wrapped prestressing reinforcement with each of the from, but failed as a result of corrosion or fire several ring sections existing precast rings and the associated tendons create a new one, the container encompassing ring force can be applied. The individual ring sections are in Circumferential direction not loaded by pressure. According to the invention within clamping channels in the multi-line Tendons laid with precast rings and surrounded with grout are there against corrosion, mechanical attacks and direct attack from naked flames. The following is the invention explained in more detail by way of example with reference to the drawing. It shows
