Abstract
Bei einer Lastverteilungsplatte soll eine Lösung geschaffen werden, die da vorzeitige Aufbringen auf die Tübbinge ermöglicht, ohne das die Witterungseinflüsse ein vorzeitiges Aufbringen unmöglich machen.Dies wird dadurch erreicht dass die blaue Gitterfolie ② auf die Holzfaserplatte ① umweltfreundlich geklebt wird. Auf der Rückseite werden ebenfalls umweltfreundlich zwei doppelseitige Klebestreifen ③ mit Gittergelege aufgebracht, siehe anliegende Zeichnung.In a load distribution plate, a solution is to be created, which allows because of premature application to the tubbings, without the weather conditions make premature application impossible.This is achieved by the blue grid film ② is adhered to the wood fiber board ① environmentally friendly. On the back side, two double-sided adhesive strips ③ are also applied in an environmentally-friendly manner with a grid of scrim, see attached drawing.
Description
Nach dem Vortrieb eines Tunnels mit einer Tunnelbohrmaschine (TBM) werden Tübbinge zu einer Röhre zusammengesetzt. Um den Pressdruck zwischen den Tübbingen zu mindern, werden Lastverteilungsplatten zwischen den Tübbingen angeordnet.After tunneling with a tunnel boring machine (TBM), segments are assembled into a tube. In order to reduce the pressure between the segments, load distribution plates are placed between the segments.
Eine solche Lastverteilungsplatte besteht aus einer 3 mm dicken, rechteckigen Holzfaserplatte, mit oder ohne Bohrungen.Such a load distribution plate consists of a 3 mm thick, rectangular wood fiber board, with or without holes.
Die Druckschrift
Tübbinge werden meist in großen Tübbinglagern unter freiem Himmel gelagert. Damit sind diese häufig für einen längeren Zeitraum der Witterung ausgesetzt. Holzfaserplatten quellen nach Feuchtigkeitsaufnahme durch wechselhafte Witterungsverhältnisse und verformen sich dadurch. Da der maximale Abstand zwischen den Tübbingen festgelegt ist, müssen verformte Lastverteilungsplatten aufwendig händisch ausgetauscht werden.Tübbinge are usually stored in large tubbing camps under the open sky. So they are often exposed to the weather for a long period of time. Wood fiber boards swell after moisture absorption by changeable weather conditions and deform thereby. Since the maximum distance between the segments is fixed, deformed load distribution plates must be exchanged by hand.
Die Aufgabe des Erfindungsgegenstandes ist es, das aufwendige händische Austauschen von gequollenen Lastverteilungsplatten zu unterbinden und dadurch die Arbeitsgeschwindigkeit zu erhöhen.The object of the subject invention is to prevent the costly manual replacement of swollen load distribution plates and thereby increase the operating speed.
Dies wird erreicht durch die Verwendung einer Holzfaserplatte mit den Merkmalen nach Anspruch 1.This is achieved by the use of a fiberboard with the features of claim 1.
Die rechteckige Holzfaserplatte wird dazu auf der einen Seite mit blauer Gitterfolie sowie auf der anderen Seite mit Selbstklebestreifen versehen. Sie eignet sich als Lastverteilungsplatte für Tübbinge.The rectangular fibreboard is provided on one side with blue mesh and on the other side with self-adhesive strips. It is suitable as a load distribution plate for segments.
Sowohl die Gitterfolie als auch die Selbstklebestreifen werden in umweltfreundlicher Weise ohne Flüssigkleber auf die Holzfaserplatte aufgebracht. Durch die Verwendung von doppelseitigen Klebestreifen ist auch die Verwendung von Schutzkleidung beim Anbringen der Lastverteilungsplatten an den Tübbingen nicht mehr nötig.Both the grid film and the self-adhesive strips are applied in an environmentally friendly manner without liquid adhesive on the wood fiber board. Through the use of double-sided adhesive strips, the use of protective clothing when attaching the load distribution plates to the segments is no longer necessary.
Eine weitere Ausgestaltung der Lastverteilungsplatte sieht vor, dass diese als Segmentbogen mit bereits eingebrachten Bohrungen gefertigt wird.Another embodiment of the load distribution plate provides that this is made as a segmental arc with holes already introduced.
