Description

GEBRAUCHSMUSTER-ANMELDUNG SPANNBAND Seit längerer Zeit verbindet man Gummimuffen mit Stahlrohren mit Hilfe sogenannter Spannbänder mit bekannten Spannschlössern. Diese Bänder bestehen aus Metall, meistens aus Stahlblech. Mit Hilfe der Schlösser zieht man die Bänder so an, daß der Gummi so stark gepresst wird, daß er sich eng um das Metallrohr schließt.UTILITY MODEL REGISTRATION TIE BAND People have been connecting for a long time Rubber sleeves with steel pipes using so-called tightening straps with known turnbuckles. These bands are made of metal, mostly sheet steel. With the help of the locks tighten the bands in such a way that the rubber is pressed so hard that it becomes tight closes around the metal tube.

Die Metallbänder, wie sie üblicherweise verwendet werden, haben einen erheblichen Nachteil, insbesondere bei Leitungen, durch die abwechselnd heiße und kalte Flüssigkeiten geführt werden. Bei solchen Leitungen tritt an dem Gummi der Muffen verhältnismäßig bald eine gewisse"Ermüdung"auf, der Gummi verliert seine reversible Dehnung, und die Leitung wird infolgedessen undicht, insbesondere dann, wenn die Flüssigkeit auf Raumtemperatur zurückgeht. Es wurde nun gefunden, daß bei Verwendung von gereckten Nylon-Bändern, die eine Festigkeit von 25 kg/mm2 besitzen, diese störenden Erscheinungen nicht auftreten. Diese Nylon-Bänder besitzen nahezu den gleichen Ausdehnungskoeffizienten wie der Gummi der Muffen. Die Spannbänder aus Nylon geben auf Grund ihres hohen Elastizitätsmoduls auch hohen Temperaturveränderungen nach, so daß auch bei größeren Rohrleitungen kein Undichtwerden mehr auftritt.The metal bands as commonly used have a significant disadvantage, especially with lines, through which alternately hot and cold liquids are conducted. With such lines occurs on the rubber Sleeves get a certain "fatigue" relatively soon, the rubber loses its reversible expansion, and the line will leak as a result, especially when when the liquid returns to room temperature. It has now been found that at use of stretched nylon tapes with a strength of 25 kg/mm2, these disturbing phenomena do not occur. These nylon bands possess nearly the same coefficient of expansion as the rubber of the sleeves. The straps due to their high modulus of elasticity, nylon also withstand high temperature changes after, so that no more leakage occurs, even with larger pipelines.
