Description
Abdichtung an schwebenden Bühnen Die zum Ausbauen von Schächten verwandte schwebende Bühne erfordert eine Abdichtung des zwischen dieser und der Schachtwand verbleibenden freien Raumes, insbesondere bei gleichzeitigem Abteufen und Ausbauen, um eine Gefährdung der auf der Schachtsohle .arbeitenden Leute durch herabfallende Gegenstände sowie Steinfall auszuschließen.Sealing on floating platforms The one used to build manholes floating stage requires a seal between this and the shaft wall remaining free space, especially with simultaneous sinking and expansion, to endanger the people working on the bottom of the shaft from falling Exclude objects and falling stones.
Die zu diesem Zweck bisher überwiegend angewandten sog. Segmentbretter, die bis@dicht an die Schichtwandung vorgeschoben werden, sind umständlich zu handhaben, hinderlich beim Verfahren der Bühne und dichten den freien Raum nur unzureichend ab.The so-called segment boards, which have so far mainly been used for this purpose, which are pushed forward to @ close to the layer wall are awkward to handle, obstructive when moving the stage and insufficiently seal the free space away.
Die Abdichtung durch einen kegel.stumpfförmigen, gegen die Schachtwandung spannbaren Blechring ist zwar einfacher durchzuführen, aber mit Nachteilen beim Verfahren der Bühne behaftet. Dies fällt um so mehr ins Gewicht, als die Schwehebühnei lyeim Mauern in relativ kurzen Absätzen, einige Male täglich, höher gefahren werden muß.The sealing by a conical, frustoconical, against the shaft wall tensionable sheet metal ring is easier to carry out, but with disadvantages Procedure tainted by the stage. This is all the more important as the silent boom lyeim walls in relatively short steps, a few times a day, are raised higher got to.
Die Verwendung .eines aufblasbaren Schlauches zum Abdichten von Türen, Lukendeckel.n u. dgl. .ist bekannt.The use of an inflatable tube to seal doors, Hatch covers and the like are known.
Die Nachteile der vorb.ezeichneten Einrichtungen werden durch die Erfindung beseitigt. Die zumeist aus einer Eisenkonstruktion bestehende, mit einem starken Bohlenbelag abgedeckte schwebende Bühne wird gewöhnlich außen durch einen gebogenen U-Eisenrahmen begrenzt. Zwischen diesem und dem Schachtmauerwerk verbleibt ein freier Raum von etwa 7o bis i oo mm. Zu dessen Abdichtung wird an den U-Eisenrahmen ein Schlauch aus weichem Gummi oder ähnlichen Stoffen mit auf dem Bohlenbelag durch Schrauben o. dgl. befestigten Hanf- oder Lederschlaufen angehängt (Fig. i).The disadvantages of the above mentioned facilities are caused by the Invention eliminated. The mostly made of an iron structure, with a Floating stage covered with thick planking is usually outside by a curved U-iron frame limited. Remains between this and the shaft masonry a free space of about 70 to 100 mm. The U-iron frame is used to seal it a hose made of soft rubber or similar material on the plank covering Screws or the like attached to attached hemp or leather loops (Fig. I).
Dieser Sehlauch ist durch einen Segeltuch-oder Hanfüberzug vor Zerstörung zu schützen. Nach Festlegen der schwebenden Bühne an der vorgesehenen Arbeitsstelle wird der Schlauch durch die im Schacht vorhandene Preßluft aufgeblasen und der freie Raum zwischen Bühne und Mauerwerk hierdurch vollständig dicht abgeschlossen (Fig. 2).This eye tube is protected from destruction by a canvas or hemp cover to protect. After fixing the floating stage at the intended work site the hose is inflated by the compressed air present in the shaft and the free This means that the space between the stage and the masonry is completely sealed off (Fig. 2).
Auf diese Weise läßt sich ein durch herabfallende Gegenstände sowie Steinfall ungefährdetes Arbeiten auf der Schachtsohle ermöglichen.In this way you can avoid falling objects as well Stone falls enable safe working on the shaft floor.
