Abstract
Description
Die nachfolgend beschriebene Erfindung betrifft eine Schalung zur Herstellung von Tübbingen aus Beton oder Stahlbeton, insbesondere eine Schalung, an der zumindest ein umlaufender Dichtungsrahmen aus einem elastomeren Werkstoff lagegenau festlegbar ist. Der Dichtungsrahmen wird bei dem anschließenden Betoniervorgang formschlüssig in den Beton einbettet.The invention described below relates to a formwork for the production of Tubbing made of concrete or reinforced concrete, in particular a formwork on the at least an encircling sealing frame made of an elastomeric material is determinable. The sealing frame becomes during the subsequent concreting process embedded in the concrete in a form-fitting manner.
Die Herstellung von Tunnelröhren aus Tübbingen ist eine seit langer Zeit bewährte Bauweise, darin eingeschlossen die druckwasserdichte Ausbildung der Längs- und Querfugen mit Hilfe von elastomeren Kompressionsdichtungsbändem oder -rahmen. Sie werden vor der Montage auf die Flanken der Tübbinge aufgeklebt oder bereits beim Betonieren in den Beton eingebettet. Ein erhebliches Problem ist bisher die lagestabile Befestigung der Dichtungsbänder oder Rahmen an der Schalung. Die punktweise Festlegung ist sehr kostenintensiv und von unbefriedigendem Erfolg.Es kann zur Girlandenbildung und zum Hinterlaufen der Dichtungsbänder mit Betonschlempe kommen. Nach dem Ausschalen und Säubem stellt man häufig Abweichungen von der Sollage und insbesondere Unebenheiten fest. Bei der Montage können unregelmäßige und ungenügende Kompressionen und als deren Folge Undichtigkeiten entstehen, vor allem dann, wenn entsprechende Fehler auch an den angrenzenden Tübbingen bzw. den dort einbetonierten Dichtungsbändem bzw. - rahmen vorhanden sind.The production of tunnel tubes from Tübbingen has proven itself for a long time Construction, including the pressure-water-tight design of the longitudinal and Transverse joints by means of elastomeric compression sealing bands or frames. They are glued on the flanks of the segments before assembly or already embedded in concrete during concreting. A significant problem so far is the stable mounting of sealing strips or frames on the formwork. The pointwise fixing is very costly and of unsatisfactory success Can be used to garland and to run behind the sealing tapes with concrete vat come. After stripping and Säubem is often deviations determined by the Sollage and in particular bumps. During installation can cause irregular and insufficient compression and as a result Leaks arise, especially if corresponding errors also in the adjoining tubbings or the sealing tapes or concretes embedded in them frame are present.
Die Dichtrahmen eines Tübbings aus Beton bestehen vielfach aus vier zusammengesetzten, im Strangpreßverfahren hergestellten Dichtprofilen, wobei die vier Rahmenecken vorzugsweise nach dem Injection-Molding-Verfahren hergestellt werden (EP-B-0 578 797). Besonders wirksam hinsichtlich ihrer Dichtfunktion sind Dichtprofile, die in Längsrichtung parallel verlaufende Kanäle besitzen (DE-C-35 02 620, EP-B-0 441 250). Infolge des Zusammenpressens der aneinanderstoßenden Tunnel-Segmente unter Verringerung des Abstandes der Quer- und Längsfugen entfaltet dann der Dichtrahmen aus elastomerem Werkstoff unter der Wechselwirkung von Kraft und Reaktionskraft seine Dichtleistung. Derartige Kompressionsdichtungen haben sich bei zahlreichen Tunnelprojekten bewährt.The sealing frames of a tubbings made of concrete often consist of four assembled, extruded sealing profiles, wherein the four Rahmenecken preferably prepared by the injection molding process (EP-B-0 578 797). Particularly effective in terms of their sealing function Sealing profiles which have longitudinally parallel channels (DE-C-35 02 620, EP-B-0 441 250). As a result of compressing the abutting Tunnel segments reducing the distance between the transverse and longitudinal joints unfolds then the sealing frame of elastomeric material under the interaction of power and reaction force its sealing performance. Such compression seals have proven themselves in numerous tunnel projects.
Häufig genügt es, wenn jeder Tübbing einen einzigen Dichtrahmen aufweist. Unter besonderen Umständen kann es jedoch erforderlich werden, die Segmente mit einem Doppeldichträhmen zu versehen, insbesondere in Verbindung mit einem in einer Querfuge einsitzenden Dichtungsquerprofil, das der Außenkontur der beiden parallel verlaufenden Dichtrahmen angepaßt ist (EP-B-0 337 177).Often it is sufficient if each tubbing has a single sealing frame. Under However, in certain circumstances it may be necessary to use a segment To provide double cable crimping, especially in conjunction with a in a Transverse joint sewn sealing transverse profile, which is the outer contour of the two parallel extending sealing frame is adapted (EP-B-0 337 177).
Bislang werden die Stoßflanken von Tübbingen aus Beton bzw. Stahlbeton überwiegend mit umlaufenden Nuten ausgebildet, in die dann der Dichtrahmen eingebracht wird, und zwar unter Verwendung von Hilfsmitteln zur Befestigung, z. B. Verdünner oder Kleber.So far, the butt edges of Tübbingen are made of concrete or reinforced concrete formed predominantly with circumferential grooves, in which then the sealing frame is introduced, using attachment means, for. B. Thinner or glue.
In der DE-A-39 34 198 ist nun erstmalig vorgeschlagen worden, Dichtrahmen mit
Verankerungsfüßen auszustatten, und zwar unter Verwendung einer
Vakuumeinrichtung als Hilfswerkzeug bei der Verschalung unter gleichzeitiger
Verankerung des Dichtrahmens im Tunnel-Segment aus Beton. Durch diese
Verankerung entfällt
Erhebliche technische Schwierigkeiten bei der Befestigung von Dichtungsrahmen an der Tübbingschalung haben jedoch dazu geführt, daß bislang die oben beschriebene klassische Bauweise bevorzugt wird. Vor allem fehlt bisher eine ausführbare Anweisung für die Ausbildung der Vakuumeinrichtung.Substantial technical difficulties in the attachment of sealing frame However, the tubbing formwork have meant that so far the above-described classic construction is preferred. Above all, an executable is missing so far Instruction for the formation of the vacuum device.
Aufgabe der Erfindung ist es daher, eine Vakuumeinrichtung zur Herstellung einer gattungsgemäßen Dichtanordnung bereitzustellen, die ein sicheres Einlegen des Dichtprofiles bzw. des Dichtrahmens im Rahmen der Formgebung des Bauteiles bzw. Tübbings gewährleistet, verbunden mit einer wirksamen Verankerung in dem Beton. Dabei muß ferner gewährleistet sein, daß bei der Formgebung nicht die Dichtleistung des Elastomerprofiles beeinträchtigt wird. The object of the invention is therefore to provide a vacuum device for producing a To provide generic sealing arrangement, the safe insertion of the Sealing profiles or of the sealing frame in the context of the design of the component or Tubbing ensures, combined with an effective anchoring in the concrete. It must also be ensured that in the shaping not the sealing performance the elastomer profile is impaired.
Gelöst wird die Aufgabe gemäß Kennzeichen des Patentanspruches 1 durch eine Vakuumeinrichtung, die folgende Teile umfaßt, nämlich
- eine Aufnahmenut für das Dichtprofil bzw, den Dichtrahmen, wobei die Aufnahmenut mit wenigstens einer integrierten Vakuumnut ausgestattet ist, die parallel zur Aufnahmenut verläuft;
- wenigstens eine, zumeist jedoch mehrere im Abstand angeordnete Vakuumbohrung/en, die mit der Vakuumnut in Verbindung steht/stehen;
- eine Verteilerleitung, die bei der Verankerung eines Dichtrahmens insbesondere als Ringleitung ausgebildet ist;
- eine Anschlußleitung, die die Verteiler- bzw. Ringleitung mit der Vakuumbohrung verbindet; sowie
- eine mit der Verteiler- bzw. Ringleitung verbundene Hauptleitung, die zum Vakuumaggregat führt.
- a receiving groove for the sealing profile or, the sealing frame, wherein the receiving groove is equipped with at least one integrated vacuum groove which is parallel to the receiving groove;
- at least one, but generally a plurality of spaced vacuum bores communicating with the vacuum groove;
- a distribution line, which is formed in particular during the anchoring of a sealing frame as a loop line;
- a lead connecting the manifold to the vacuum bore; such as
- a main line connected to the manifold or loop leading to the vacuum unit.
Im folgenden werden die wesentlichen zweckmäßigen Konstruktionsmerkmale der erfindungsgemäßen Vakuumeinrichtung nach den Patentansprüchen 2 bis 13 genannt, wobei eine ausführliche Darlegung im Rahmen der Figurenbeschreibungen erfolgt.
- Es sind zwei parallele Vakuumnuten vorhanden, die außerhalb des Bereiches der Vakuumbohrung durch eine Abstützung für den Rücken des Dichtprofiles bzw. des Dichtrahmens getrennt sind. Dabei sind die beiden Vakuumnuten spiegelsymmetrisch zur Mittelebene der Vakuumbohrung angeordnet.
- Die Vakuumnut ist in Längsrichtung segmentiert, und zwar unter Bildung von Vakuumzonen. Innerhalb jedes Segmentes sind ferner wenigstens zwei, insbesondere wenigstens drei Vakuumbohrungen vorhanden.
- Die Anschlußleitung ist flexibel, insbesondere unter Verwendung flexibler Schläuche aus Kunststoff, Gummi oder Metall.
- Die Verteiler- bzw. Ringleitung ist mit einer T-förmigen Abzweigung versehen, wobei die Abschlußleitung das Abzweigstück mit der Vakuumbohrung verbindet.
- Die Anschlußleitung ist mit einem Ventil zwecks Regulierung des Vakuumvorganges, beispielsweise in Form eines Kugelhahnes, ausgestattet. Diese konstruktive Variante wird dabei insbesondere in Verbindung mit der Segmentierung der Vakuumnut herangezogen, und zwar unter dem Gesichtspunkt separat schaltbarer Vakuumzonen.
- Die Anschlußleitung ist ein Leitungssystem. Diese konstruktive Variante wird dabei ebenfalls insbesondere in Verbindung mit der Segmentierung der Vakuumnut angewandt. Hiernach besteht das Leitungssystem aus einer Hauptanschlußleitung, in die das oben beschriebene Ventil eingebaut ist, sowie aus mehreren Nebenanschlußleitungen, die sich zwischen dem Ventil und den Vakuumbohrungen befinden, wobei jeweils eine Nebenanschlußleitung mit einer Vakuumbohrung in Verbindung steht.
- Die Aufnahmenut für das Dichtprofil bzw. den Dichtrahmen ist beidseitig in Längsrichtung mit einer Einkerbung ausgestattet, und zwar für die Aufnahme von Haltenasen als Teil des Dichtprofiles bzw. Dichtrahmens, wobei die Haltenasen insbesondere außerhalb des Bereiches der Rahmenecken vorhanden sind.
- Die Vakuumnut ist so gestaltet, daß im Bereich der Rahmenecken kein Vakuum vorhanden ist. In Verbindung mit dieser konstruktiven Variante sollten dann jedoch die beiden zumeist schrägen Flanken der Aufnahmenut mit je einer Dichtlippe abgeschlossen sein, wobei die Dichtlippen ein Teil des Dichtprofiles bzw. Dichtrahmens sind und dabei vorzugsweise ausschließlich im Bereich der Rahmenecken vorhanden sind.
- There are two parallel vacuum grooves, which are separated outside the region of the vacuum bore by a support for the back of the sealing profile or the sealing frame. The two vacuum grooves are arranged mirror-symmetrically to the median plane of the vacuum bore.
- The vacuum groove is segmented longitudinally to form vacuum zones. Within each segment, there are at least two, in particular at least three, vacuum bores.
- The connection line is flexible, in particular using flexible hoses made of plastic, rubber or metal.
- The manifold is provided with a T-shaped branch, the termination line connecting the branch piece to the vacuum bore.
- The connection line is equipped with a valve for the purpose of regulating the vacuum process, for example in the form of a ball valve. This structural variant is used in particular in connection with the segmentation of the vacuum groove, specifically from the point of view of separately switchable vacuum zones.
- The connection line is a line system. This structural variant is also used in particular in connection with the segmentation of the vacuum groove. Thereafter, the conduit system consists of a main connection line, in which the valve described above is installed, as well as a plurality of auxiliary connection lines, which are located between the valve and the vacuum holes, wherein each auxiliary line is in communication with a vacuum bore.
- The receiving groove for the sealing profile or the sealing frame is provided on both sides in the longitudinal direction with a notch, specifically for the reception of retaining lugs as part of the sealing profile or sealing frame, wherein the retaining lugs are present in particular outside the region of the frame corners.
- The vacuum groove is designed so that there is no vacuum in the area of the frame corners. In conjunction with this constructive variant, however, then the two mostly oblique flanks of the receiving groove should be completed with a respective sealing lip, wherein the sealing lips are part of the sealing profile or sealing frame and are preferably present only in the frame corners.

Im Bereich 6 der Aufnahmenut 2 sind die Vakuumnuten 3, 3' in Längsrichtung
unterbrochen, und zwar unter Bildung von Vakuumzonen u, v, w, wobei hier innerhalb
der Vakuumzone v drei Vakuumbohrungen 4, 4', 4" vorhanden sind.In the
Die Fig. 2 veranschaulicht nochmals das Zusammenwirken von Aufnahmenut 1,
Vakuumnuten 3, 3' und Vakuumbohrung 4, wobei die beiden Vakuumnuten
spiegelsymmetrisch zur Mittelebene X der Vakuumbohrung angeordnet sind. Die
Aufnahmenut ist dabei im Bereich der Flanken 2 beidseitig in Längsrichtung mit einer
Einkerbung 7 versehen, deren Bedeutung in Verbindung mit der Fig. 3b noch näher
erläutert wird.2 again illustrates the interaction of receiving
Die Fig. 3a und 3b zeigen nochmals das Formwerkzeug I gemäß Fig. 1 und 2.
Zunächst wird das Dichtprofil 8 mit den beiden Verankerungsfüßen 9 in die
Aufnahmenut 1 eingesetzt. Durch die Verankerung der beiden Haltenasen 10 in den
Einkerbungen 7 erfolgt eine Vorfixierung des Dichtprofiles. Die endgültige Fixierung
wird dann mittels Vakuum hergestellt.FIGS. 3a and 3b again show the mold I according to FIGS. 1 and 2. First, the sealing
Nach der endgültigen Fixierung des Dichtprofiles 8 erfolgt der Vorgang des
Betonierens, wobei das Vakuum erst nach Beendigung des Betonier- und
Rüttelvorganges abgeschaltet wird, um eine unerwünschte Verlagerung des
Dichtprofiles in der Schalung zu vermeiden.After the final fixation of the sealing
Die Fig. 3c zeigt nun das im Bauteil 11 bzw. Tunnel-Segment (Tübbing) verankerte
Dichtprofil 8. FIG. 3c now shows the sealing
Die Fig. 4 veranschaulicht nun eine schematische Darstellung der Tübbingschalung, umfassend das umlaufende Formwerkzeug I, in der der Dichtrahmen 8' einsitzt, sowie das Formwerkzeug II, in das bei der Herstellung von Stahlbeton-Tübbingen ein Bewehrungkorb eingelegt ist.4 now illustrates a schematic representation of the tubbing formwork, comprising the encircling mold I , in which the sealing frame 8 'is seated, and the mold II , in which a reinforcing cage is inserted in the production of reinforced concrete tubbing.
Die Vakuumeinrichtung als integriertes Teil des Formwerkzeuges I ist mit einer
Ringleitung 12 versehen, die über eine Hauptleitung 13 mit dem Vakuumaggregat 14
verbunden ist, das zur Erzeugung eines 100 %-igen Vakuums mit einem
unterdruckstabilen Tank (Volumen etwa 0,5 m3) ausgestattet ist.The vacuum device as an integrated part of the molding tool I is provided with a
Die Ringleitung 12 ist mit einer T-förmigen Abzweigung versehen, wobei die flexible
Anschlußleitung 16 - hier als Leitungssystem ausgebildet - jeweils mit vier
Vakuumbohrungen verbunden ist. Die beiden Vakuumnuten sind gemäß Fig. 1
segmentiert, und zwar unter Bildung von beispielsweise insgesamt vierzehn
Vakuumzonen u, v, w. The
Das Leitungssystem 16 besteht aus einer Hauptanschlußleitung 16', in die das Ventil
17 in Form eines Kugelhahnes eingebaut ist, sowie aus vier Nebenanschlußleitungen
16", die sich zwischen dem Ventil und den Vakuumbohrungen befinden, wobei jeweils
eine Nebenanschlußleitung mit einer Vakuumbohrung in Verbindung steht.The
Im Hintergrund dieses Anordnungsprinzipes sind die Vakuumzonen u, v, w separat
schaltbar. Eine vorteilhafte Reihenschaltung besteht darin, zunächst die Vakuumzonen
w, die der Rahmenecke 8" am nächsten liegen, durch Öffnen der
entsprechenden Ventile mit Vakuum zu beaufschlagen, womit die endgültige Fixierung
im Rahmeneckenbereich gegeben ist. Danach werden die Rahmenmittelteile durch
Öffnung der entsprechenden Ventile mit Vakuum (Vakuumzonen u, v) beaufschlagt,
bis dann der gesamte Dichtrahmen 8' endgültig fixiert ist.In the background of this arrangement principle, the vacuum zones u, v, w are separately switchable. An advantageous series connection consists in initially applying vacuum to the vacuum zones w closest to the
Die Vakuumnut ist ferner so gestaltet, daß im unmittelbaren Bereich der Rahmenecke
8' kein Vakuum vorhanden ist. Der Grund in dieser Maßnahme ist darin sehen, daß die
Rahmenecke 8" herstellungsbedingt häufig nicht exakt in der Aufnahmenut einliegt, so
daß unter Vakuum Betonschlämme in den Bereich der Nutflanken 2 (Fig. 1, 2)
eindringen kann. Daher ist für den Bereich der Rahmenecke 8" eine modifizierte
Lösung gefunden worden, die nun im folgenden vorgestellt wird.The vacuum groove is further designed so that in the immediate area of the frame corner 8 ' no vacuum is present. The reason for this measure is that the
Die Fig. 5 zeigt den kompletten Dichtrahmen 8', der aus vier zusammengesetzten
strangförmigen Dichtprofilen 8 sowie aus vier Rahmenecken 8" besteht.5 shows the complete sealing frame 8 ' , which consists of four composite strand-shaped
Während das Dichtprofil 8 gemäß Fig. 6, das bereits in Verbindung mit der
Figurenbeschreibung 3a, 3b und 3c vorgestellt wurde, mit Haltenasen 10 versehen ist,
weist die Rahmenecke 8" anstelle Haltenasen zwei Dichtlippen 18 auf. Auf diese
Weise werden die Flanken 2 der Aufnahmenut 1 (Fig. 1, 2, 3a, 3b) abgeschlossen.
Diese Dichtlippen reduzieren einerseits die Luftverluste und anderseits stellen sie eine
wirksame Sperre gegen Eindringen von Betonschlämpe im Bereich der Rahmenecke
dar.While the sealing
Auch wenn der erfindungsgemäßen Vakuumeinrichtung im Rahmen des Tunnelbaues eine herausragende Bedeutung zukommt, so läßt sich dieses Prinzip auch bei der Herstellung anderer Dichtanordnungen verwirklichen, beispielsweise beim Abdichten von Muffenrohren beim Kanalbau (DE-C-35 07 909, EP-B-0 449 082). Dabei ist hier das Dichtprofil als ringförmiger Dichtrahmen (Dichtring) ausgebildet.Even if the vacuum device according to the invention in the context of tunneling plays a prominent role, so this principle can be in the Manufacture other sealing arrangements realize, for example, when sealing of socket pipes in sewer construction (DE-C-35 07 909, EP-B-0 449 082). It is here the sealing profile as an annular sealing frame (sealing ring) is formed.
Ferner ist die erfindungsgemäße Vakuumeinrichtung nicht nur auf die Herstellung von Dichtanordnungen beschränkt, bei denen das Bauteil aus Beton oder Stahlbeton besteht, sondern auch zur Herstellung von Kunststoffrohren, beispielsweise von GFK-Rohren, mit verankertem Dichtring geeignet.Furthermore, the vacuum device according to the invention is not limited to the production of Limited sealing arrangements in which the component of concrete or reinforced concrete exists, but also for the production of plastic pipes, for example of GRP pipes, with anchored sealing ring suitable.
