Description

Nach dem Hauptpatent 876 230 wird der Deckel für Propeller- oder Kaplantu.rbinen großer Leistung als geschweißte kegelstumpfschalenförmige Tragkonstruktion ausgebildet, derart, daß die Kräfte aus der Belastung des Deckels ausschließlich durch eine oder mehrere durch starke Verbinsdungsringe miteinander verbundene Schalen auf den Auflagerflansch übertragen werden. Durch eine solche Ausbildung wird die rotationssymmetrisch auf den Deckel eingeleitete Belastung bei geringem Materialaufwand sicher und mit geringer Durchbiegung des Deckels über den für die Wasserführung erforderlichen Spalt hinweg auf den Stützschaufelring und über die Stützschaufeln auf das Fundament weitergeleitet. In gleicher Weise können auch zu ähnlichen Aufgaben dienende Tragringe (Getriebetragringe, Schachtringe od. dgl.) ausgebildet werden.According to the main patent 876 230 , the cover for propeller or Kaplantu.rbinen is designed as a welded frustoconical shell-shaped support structure, so that the forces from the load on the cover are transmitted to the support flange exclusively through one or more shells connected to one another by strong connecting rings. With such a design, the load applied to the cover in a rotationally symmetrical manner is transmitted safely and with little deflection of the cover over the gap required for the water flow to the support blade ring and via the support blades to the foundation with little material expenditure. In the same way, support rings (gear support rings, manhole rings or the like) serving for similar tasks can also be formed.

Gemäß der Zusatzerfindung wird vorgeschlagen, den zur Aufnahme von Ringspannungen dienenden und gleichzeitig den Auflagerflansch bildenden starken Ring am äußersten Rand der Kegelstumpfschale in Verbundbauweise aus Stahl und Beton herzustellen. Die bei der Belastung eintretende Deformation solcher nach dem Hauptpatent ausgebildeten Turbinendeckel bzw. Tragringe ist zumeist für die zu wählenden Abmessungen maßgebend, während die auftretenden Spannungen nur sehr gering sind. Den größten Einfluß auf die Senkung des Tragringes hat nun der Flansch am größten Durchmesser, da dessen Nachgiebigkeit bzw. Durchmesserverkleinerung den größten Teil der gesamten Senkung bedingt. Will man daher eine möglichst kleine Durchsenkung erhalten, so muß der äußere Flansch besonders stark ausgeführt werden. Dies bereitet bei geschweißten Ausführungen unter Umständen gewisse Schwierigkeiten, weil dort OOuerschnitte sehr verschiedener Stärke miteinander zu verbinden sind.According to the additional invention, it is proposed to accommodate the Ring tensions serving and at the same time the support flange forming strong Ring on the outermost edge of the truncated cone shell in composite construction made of steel and concrete to manufacture. The deformation occurring during loading such according to the main patent trained turbine cover or support rings is mostly for the dimensions to be selected decisive, while the stresses that occur are only very low. The biggest The flange at the largest diameter now has an influence on the lowering of the support ring, since its resilience or reduction in diameter accounts for the greater part of the entire Reduction conditional. If you want to get the smallest possible depression, so the outer flange must be made particularly strong. This prepares for welded Executions may have certain difficulties, because there are a lot of cuts of different strengths are to be connected with each other.

Durch die vorgeschlagene Verbundbauweise in Stahl und Beton, bei der der Kegelstumpfmantel am äußeren Rand mit einigen angeschweißten Schubbewehrungen versehen und mit Beton ausgegossen wird, kann unter wesentlicher Verringerung der Herstellungskosten eine große Steifigkeit des äußeren Flansches und damit auch der tragenden Kegelschale erzielt werden.Due to the proposed composite construction in steel and concrete, in which the outer edge of the truncated cone with some welded shear reinforcements provided and poured with concrete can significantly reduce the Manufacturing costs a great rigidity of the outer flange and thus also the bearing cone shell can be achieved.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt. Die Abbildung zeigt schematisch einen Turbinendeckel, der in Richtung des eingezeichneten Pfeiles r am inneren Ring :2 rotationssymmetrisch belastet ist. Diese Belastung wird über die Kegelstumpfschale 3 auf den äußeren Ring übertragen. Dieser besteht aus dem Auflagerflansch q. und dem durch die Zylinderbleche 5, 6 und 7 und die weitere Kegelstumpfschale 8 gebildeten Kasten g. Die Betonfüllung ist durch besondere als Schubbewehrung dienende Zuganker io und Ringstäbe ii gesichert.The invention is shown in the drawing in an exemplary embodiment. The figure shows schematically a turbine cover, which is in the direction of the drawn Arrow r on the inner ring: 2 is loaded rotationally symmetrical. This burden is transferred to the outer ring via the truncated cone shell 3. This exists from the support flange q. and through the cylinder sheets 5, 6 and 7 and the other Truncated cone shell 8 formed box g. The concrete filling is by special than Shear reinforcement serving tie rods io and ring bars ii secured.
