Description
Verfahren zum Walzen T-förmiger Spundwandbohlen Das Walzen von T-förmigen Stahlspundbohlen mit klauenartigen Schloßteilen an den Flanschenenden in. einer Hitze stieß bisher auf Schwierigkeiten. Es war also nicht möglich, die bei der späteren Herstellung von verschiedenen Spundwandgrundrißformen auf Zug beanspruchten Schloßteile in einer Hitze fertig auszuwalzen. Solche Teile wurden nach dem Walzen umgebogen. Ein scharfes nachträgliches Umformen ist sehr gefährlich, da hierbei die Schloßteile leicht einreißen. Die Schloßverbindungen der einzelnen Bohlen werden durch das Einreißen stark geschwächt, und der Zusammenhalt, die Standfestigkeit sowie die Wasserdichtigkeit einer aus solchen Bohlen hergestellten Spundwand ist gefährdet. Auch sprangen die artgewalzten Schloßverbindungen von bisher im Handel befindlichen gewalzten T-förmigen Stahlspundbohlen vor die Spundwandflucht, so daß die Schloßteile immer starken Beschädigungen ausgesetzt waren bzw. solche verursachten. Die Herstellung einer vollkommen glatten Spundwand mit artgewalzten klauenartigen Schloßteilen war bisher nicht ausführbar.Method of rolling T-shaped sheet piles The rolling of T-shaped Steel sheet piles with claw-like lock parts at the flange ends in one Heat has encountered difficulties so far. So it was not possible for the later one Manufacture of various sheet pile wall plan shapes subject to tension lock parts finish rolling in a heat. Such parts were bent over after rolling. A sharp subsequent reshaping is very dangerous, as this would damage the lock parts tear easily. The lock connections of the individual planks are torn severely weakened, and the cohesion, stability and waterproofness a sheet pile wall made from such planks is at risk. They jumped too type-rolled interlock connections from previously commercially available rolled T-shaped ones Steel sheet piles in front of the sheet pile wall, so that the lock parts are always heavily damaged were exposed or caused such. Making a perfectly smooth Sheet pile wall with type-rolled claw-like interlock parts was previously not feasible.
Diese Nachteile werden durch das neue Walzverfahren vermieden. Die neue T-förmige Stahlspundbohle wird in einer Hitze in einem kelchförmigen Querschnitt gewalzt. Alle auf Zug beanspruchten Schloßteile 3 befinden sich im Urwalzzustand, sind also in der gleichen Hitze geformt worden. Die Schloßteile z erhalten schlanke Abmessungen und werden beim Walzen in derselben Hitze, in der der kelchförmige Querschnitt gewalzt wird, in flachem Bogen umgelegt, damit sich die Dehnungen oder Quetschungen des Baustoffes auf die ganze Länge der Nase auswirken können, so daß ein Einreißen des Baustoffes nicht erfolgt. Nach dem Umlegen der Schloßteile a werden die Flanschen gestreckt oder zurückgebogen, so daß die Schloßverbindungen hinter der Flanschenfront liegen. Es ist hierbei gleichgültig, wie weit die Flanschen zurückgebogen werden. Aus den Spundbohlen mit gestreckten oder gekrümmten Flanschen lassen sich verschiedenartig gestaltete Spundwandgrundrißformen zusammenstellen, die entweder vollkommen glatte Innen- oder Außenflächen haben.These disadvantages are avoided by the new rolling process. the new T-shaped steel sheet pile is in a heat in a goblet-shaped cross-section rolled. All lock parts 3 stressed in tension are in the original rolling condition, so were formed in the same heat. The lock parts z get slim Dimensions and are rolled in the same heat as the cup-shaped cross-section is rolled, folded in a flat arc, so that the stretching or bruising of the building material can affect the entire length of the nose, so that it tears of the building material does not take place. After turning over the lock parts a, the flanges stretched or bent back so that the lock connections are behind the flange front lie. It does not matter how far the flanges are bent back. The sheet piles with straight or curved flanges can be used in various ways Put together designed sheet pile wall plan shapes that are either completely smooth Have interior or exterior surfaces.
