Abstract

The flexible joint gap seals are placed between the tubular sections or pipelines or tunnel sections. These seals are held on the flanges at the end of the section by means of clamping brackets. The replaceable gap seal is held by the clamping brackets on the flanges of the tubular section. The edges of the seal are pressed against the flat flange by the bracket clamping arm and by the pressure of the clamping bolt. No bolt holes are drilled either into the tubular section nor into the seal. The seal is readily clamped into position or dismantled simply by releasing the clamping bracket.

Verfahren zur Befestigung von auswechselbaren FugenbändernMethod of fastening interchangeable waterstops

Gegenstand des Hauptpatents ... (Patentanmeldung P 17 59 972.3) ist ein Verfahren zur Befestigung von auswechselbaren Fugenbäiidem, welches dadurch gekennzeichnet ist, dass der dichtende Anpressdruck über Druckschienen durch Klemmplatten erzeugt wird.Subject of the main patent ... (patent application P 17 59 972.3) is a method of fastening interchangeable joint tape, which is characterized in that the sealing contact pressure is generated via pressure rails by clamping plates.

Dieses Verfahren hat den Vorteil, dassThis procedure has the advantage that

1. die Fugenbänder unbeschädigt, d.h. undurchbohrt eingebaut werden.1. the waterstops are undamaged, i.e. installed without being drilled through.

2. Die Druckschienen undurchbohrt eingebaut werden,2. The pressure rails are installed without drilling,

3. Der Ausbau und die Auswechslung des Fugenbands wesentlich vereinfacht und damit beschleunigt wird.3. The expansion and replacement of the joint tape is significantly simplified and thus accelerated.

Die verwendeten Kleinmplatten haben etwa die Form solcher Klemmplatten, die u.a. zur Befestigung von Schienen benutzt werden. Die Befestigung dieser Klemmplatten und der Druck werden mittels Steinschrauben bewerkstelligt, die ausserhalb des Fugenbands und der Druckschienen in die zu verbindenden Betonteile eingelassen sind. ,The small plates used have roughly the shape of such clamping plates, which are used, among other things, for fastening rails. The fastening of these clamping plates and the pressure are by means of Brick screws accomplished, which are embedded outside the joint tape and the pressure rails in the concrete parts to be connected are. ,

Bei der weiteren Ausbildung dieses Verfahrens wurde nun gefunden, dass "sich das Prinzip dieses Verfahrens auch auf die Verbindung von Tübbingen mittels Fugenbändern anwenden lässt, wenn anstelleIn the further development of this process it has now been found that "the principle of this process also applies to the connection of segments using waterstops, if instead

der Klemmplatten Klemmvorrichtungen mit Bügelform verwendet werden.the clamping plates clamping devices with a bow shape can be used.

Gegenstand der Erfindung ist daher ein Verfahren zur Befestigung von auswechselbaren Pugenbändern, bei dem der dichtende Anpressdruck über Druckschienen durch Klemmplattcn erzeugt wird, welches dadurch gekennzeichnet ist, dass anstelle von Klemmplatte!! Klemmvorrichtungen mit Bügelform verwendet werden.The subject of the invention is therefore a method for fastening exchangeable Pugenbands in which the sealing Contact pressure is generated via pressure rails by Klemmplattencn, which is characterized in that instead of Clamp !! Clamping devices with bow shape are used.

Beim Zusammenfügen von Tübbingen zu Rohrleitungen oder Tunnels müssen nach jedem einzelnen oder nach einer Gruppe von Tübbingen dichtende, dauerelastische Verbindungselemente eingebaut werden, wenn sie Berg- oder Bodensenkungen ausgesetzt sind und das Eindringen von Wasser verhindert werden soll. Als Verbindungselemente dienen dauerelastische Fugenbänder. Deren Verbindung mit den Tübbingen erfolgte bisher mittels Schrauben über Druckschienen an den Tübbingschenkeln. Dabei müssen die Löcher für die Schrauben in Druckschiene, Fugenband und Tübbingschenkel genau übereinander liegen. Falls die Schraube nicht durch den Tübbingschenkel durchgeht, sondern darauf angeschweisst ist, muss die Lage der Schraube genau mit der Lage der Löcher in Fugenband und Druckschiene übereinstimmen. Dies ist in der Praxis schwierig zu erreichen. Im Fugenband ändert sich die Lage der Löcher gegenüber den Löchern in den Metallteilen infolge der bei Kunststoffen viel stärkeren Abhängigkeit der Längenausdehnung von der Temperatur. Dies hat bereits in der Vergangenheit in einer Reihe von Fällen dazu geführt, dass die Löcher sich so wenig deckten, dass die Fugenbänder nicht eingebaut werden konnten. Bei geringeren Verschiebungen der Löcher kann das Fugenband beim Einbau so gestaucht werden, dass der das Eindringen von Wasser verhindernde dichte Sitz infrage gestellt wird."When joining segments to form pipelines or tunnels, after each individual segment or after a group of segments Sealing, permanently elastic connecting elements are installed if they are exposed to subsidence or subsidence and the penetration should be prevented by water. Permanently elastic joint tapes serve as connecting elements. Their connection The segments were previously carried out using screws on pressure rails on the segment legs. The holes for the screws in the pressure rail, joint tape and segment leg are exactly on top of each other. If the screw does not go through the Segment leg goes through, but is welded to it, the position of the screw must match the position of the holes in Joint tape and pressure rail match. This is difficult to achieve in practice. The situation changes in the joint tape of the holes compared to the holes in the metal parts due to the much stronger dependence of the linear expansion in plastics on the temperature. This has already caused the holes in a number of cases in the past So little coincided that the waterstops could not be installed. With minor displacements of the holes can The joint tape is compressed during installation in such a way that the tight fit preventing the ingress of water is compromised will."

In der beigefügten Abbildung wird die Befestigung eines auswechselbaren Fugenbands an einem Tübbingschenkel näher erläutert t Das auswechselbare Fugenband (i) wird über die ungelochte Druckschiene (2) durch die bügeiförmige Klemmvorrichtung (3) beim Anziehen der Klemmschraube (k) an den Tübbingschenkel (5) angepresst.The attachment of an exchangeable joint tape to a segment leg is explained in more detail in the attached illustration t The replaceable joint tape (i) is attached to the segment leg (5) via the unperforated pressure rail (2) through the bracket-shaped clamping device (3) when the clamping screw (k) is tightened. pressed on.

Der durch die Klemmschraube bewirkte Anpressdruck, mit dem das Fugenband gehalten wird, muss mindestens der Reissfestigkeit des Fugenbands entsprechen, damit auch bei extremer Verzerrung das Fugenband nicht aus seinem Sitz herausgerissen werden kann.The contact pressure caused by the clamping screw, with which the joint tape is held, must be at least the tensile strength of the joint tape so that the joint tape is not torn out of its seat even in the event of extreme distortion can be.
