Abstract
Description
Aufgabe der ErfindungObject of the invention
Die Erfindung betrifft eine Vorrichtung zur Abschottung eines Leitungsstrangs, der im Oberbegriff von Patentanspruch 1 genannten Art. Derartige Vorrichtungen dienen dem Abdrücken und Verschliessen von, durch Wände oder Decken hindurchgeführten Rohrleitungen oder Kabelkanälen im Brandfall. Derartige Leitungsstränge bestehen dabei insbesondere aus Kunststoff oder einem anderen, bei erhöhten Temperaturen nachgiebigen oder weichen Material.The Invention relates to a device for partitioning a wiring harness, referred to in the preamble of claim 1. Art. Such devices serve for pushing and closing, through walls or ceilings passed through pipes or cable ducts in case of fire. Such strands exist in particular made of plastic or another, at elevated temperatures compliant or soft material.

der
Im Brandfall kann es nach dem Expandieren des intumeszierenden Elements noch zu Zugkräften und Ausdehnungen an der ggf. teilweise zerstörten Leitung kommen, die die Dichtigkeit der Abschottung beeinträchtigen können.in the Fire may occur after expanding the intumescent element still to tensile forces and expansions of the possibly partially destroyed ducts that affect the tightness of the foreclosure can.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Abschottung von Leitungs- oder Kanalsträngen bereitzustellen, die die genannten Nachteile vermeidet und die ein zuverlässiges Abdrücken bzw. Verschliessen einer im Brandfall nachgiebigen Rohrleitung, wie z. B. einer Kunststoffrohrleitung, ermöglicht.Of the present invention is based on the object, a device provide for the separation of line or channel strands, which avoids the disadvantages mentioned and which is a reliable Pressing or closing a fire in the event of fire Pipe, such. B. a plastic pipe allows.
Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass an dem Gehäuse der Vorrichtung wenigstens ein weiteres intumeszierendes Element angeordnet ist, das bei einer zweiten Initial-Reaktionstemperatur auslösbar ist, wobei die zweite Initial-Reaktionstemperatur höher ist als die erste Initial-Reaktionstemperatur des anderen intumeszierenden Elements. Durch diese Massnahme wird eine weitere Schottung bzw. Nachschäumung im Brandfall erreicht, die Undichtigkeiten durch eine Rohrausdehnung etc. verhindert. Als Initial-Reaktionstemperatur wird dabei die über die Materialzusammensetzung voreingestellte Temperatur verstanden, bei der das Expandieren des intumeszierenden Elements einsetzt. Vorzugsweise sind die intumeszierenden Elemente dabei in dem Gehäuse angeordnet, um eine gute Abstützung nach radial aussen zu gewährleisten, wenn die intumeszierenden Elemente expandieren.According to the invention the object is achieved in that on the housing the device at least one further intumescent element is arranged at a second initial reaction temperature is triggerable, wherein the second initial reaction temperature is higher than the first initial reaction temperature of other intumescent element. This measure becomes one further partitioning or foaming in case of fire is reached, the leaks prevented by a tube expansion, etc. When Initial reaction temperature is the pre-set via the material composition Temperature understood, at which the expansion of the intumescent Elements insert. Preferably, the intumescent elements In this case, arranged in the housing to a good support to ensure radially outward when the intumescent Expand elements.
Vorteilhaft liegt die erste Initial-Reaktionstemperatur in einem Bereich von 100°C bis 200°C, wodurch im Brandfall eine rechtzeitige Abschottung des Leitungsstranges erfolgt.Advantageous the first initial reaction temperature is within a range of 100 ° C to 200 ° C, resulting in a timely fire Partitioning of the wiring is done.
Von Vorteil ist es ferner, wenn die zweite Initial-Reaktionstemperatur in einem Bereich von 160°C bis 350°C liegt. Hierdurch wird bei weiterem ansteigen der Temperatur im Brandfall von wenigstens 60° bis 250°C ein zeitverzögertes weiteres bzw. erneutes Abdichten bzw. Abschotten des Leitungsstranges erreicht.From It is also advantageous if the second initial reaction temperature in a range of 160 ° C to 350 ° C. hereby will continue to rise in case of fire of at least 60 ° to 250 ° C a time-delayed further or re-sealing or Abschotten the cable harness reached.
Günstig ist es auch, wenn in dem Gehäuse ein ringförmiger Aufnahmeraum für die intumeszierenden Elemente vorgesehen ist, wodurch diese wenigstens in axialer Richtung fixiert werden können und gegen ein Herauslösen aus dem Gehäuse im Brandfall gesichert sind.Cheap it is also when in the housing an annular Recording room intended for the intumescent elements is, whereby they are fixed at least in the axial direction can and against being detached from the case secured in case of fire.
Vorteilhaft sind die intumeszierenden Elemente in einer axialen Richtung der Durchführöffnung aufeinanderfolgend angeordnet. Da die grössten Schäden im Schott durch eine Rohrlängendehnung entlang der Rohrachse entstehen, kann durch diese Massnahme die bestmögliche Wiederherstellung der Abschottung erzielt werden.Advantageous are the intumescent elements in an axial direction of the Passage opening arranged successively. Since the largest damage in the bulkhead by a tube elongation arise along the pipe axis, can by this measure the achieved the best possible recovery of foreclosure become.
Der Halt der intumeszierenden Elemente kann noch dadurch verbessert werden, dass in dem ringförmigen Aufnahmeraum eine Trennwand zum Aufteilen des Aufnahmeraums in wenigstens zwei Teilaufnahmeräume angeordnet ist, so dass jedes der intumeszierenden Elemente in einem der Teilaufnahmeräume angeordnet ist.Of the Stop the intumescent elements can still be improved be that in the annular receiving space a partition for dividing the receiving space into at least two partial receiving spaces is arranged so that each of the intumescent elements in one the part receiving spaces is arranged.
Vorteilhaft ist der Aufnahmeraum umfänglich um die Durchführöffnung herum im Gehäuse angeordnet, wodurch ein gleichmässiges Abdrücken der Rohrleitung im Brandfall erzielt wird.Advantageous the receiving space is circumferentially around the passage opening arranged around in the housing, creating a uniform Pressing the pipeline in case of fire is achieved.
In den Zeichnungen ist die Erfindung in zwei Ausführungsbeispielen dargestellt.In In the drawings, the invention in two embodiments shown.
