Abstract

A double fire protection is achieved, the cable also giving fire protection from the outside, such that the insulating layer formation is activated by the external heating and the foam insulation surrounds the individual conductors. By the extension of the cable by several metres, many small wall compartments are saved. USE/ADVANTAGE - Double fire protection for cables, i.e., external heating and internal heating from overloading. Does not need housing in protective ducting. (3pp Dwg.No.0/1 Poor quality original)

Description

Stand der TechnikState of the art

Es ist bekannt, daß Kabel durch Fiebersilikatplatten gegen Brand­ einwirkung geschützt werden (siehe Format Feuerschutz Katalog, Seite 63 Elektroanlagen). Für die Abschottung von Kabeldurchführungen sind ferner stahlblech-umhüllte Kabelboxen mit auf schaumbaren Platten, welche im Brandfall den Hohlraum durch Zuschäumen verschließen, bekannt (siehe Prüfbericht des Instituts für Bautechnik, Berlin, Zul.-Nr. 2-19.15-202).It is known that cables through febrile silicate plates against fire be protected (see format fire protection catalog, Page 63 electrical systems). For the sealing of cable entries are also steel sheet-encased cable boxes with foamable Panels that close the cavity by foaming in the event of a fire, known (see test report of the Institut für Bautechnik, Berlin, Permit no. 2-19.15-202).

Der Erfindungsgedanke istThe idea of the invention is

  • - für Notstrom-Kabel einen selbständigen Kabelkanal in beliebiger Länge und Querschnitt mit verschiedenen Formstücken zu erstellen, der bei einer Brandeinwirkung von innen, z. B. der Kabelüberlastung und Erhitzung eines einzelnen Kabels, die Funktionsfähigkeit der anderen Kabel trotz des Zuschäumens der Hohlräume erhält,- For emergency power cables, an independent cable channel in any Create length and cross section with different fittings, the in the event of fire from the inside, e.g. B. the cable overload and heating a single cable, the operability of the receives other cables despite the foaming of the cavities,
  • - ein doppelter Brandschutz dadurch gegeben ist, daß der Kanal als solcher Brandschutz von außen bietet und bei einer Brandeinwirkung von außen sich erhitzt und dadurch innen, bedingt durch die Erhitzung und infolge dessen der Auslösung des Aufschäumens für jedes ein­ zelne Kabel zusätzlich schutzbringend wirkt.- A double fire protection is given in that the channel as offers such fire protection from the outside and in the event of fire heats up on the outside and therefore on the inside, due to the heating and consequently triggering the foaming for each one individual cables also have a protective effect.

Weiterer Erfindungsgedanke ist,
durch den Aufbau des Kabelkanals in fugenversetztes Arbeiten wie bisher unnötig zu machen, auch bei den Formstücken.Another idea of the invention is
by the construction of the cable duct in joint-staggered work as before, even with the fittings.

Mit dieser Erfindung kann man auf einmal sämtliche Probleme, die im Kabelbrandschutz auftreten, lösen, sowohl den Funktionserhalt der Kabel bei einer Erhitzung von innen oder außen, als auch das Problem der Abschottung bei Brandwanddurchbrüchen. With this invention one can solve all the problems at once occur in the cable fire protection, solve both the function maintenance the cable when heated from the inside or outside, as well Foreclosure problem in case of fire wall breakthroughs.  

Beschreibung der ZeichnungDescription of the drawing

Im Kabelkanal befinden sich z. B. drei Notstromkabel.In the cable duct are z. B. three emergency power cables.

2 zeigt ein überhitztes Kabel, welches von dämmschichtbildendem Material 4 im Bereich 3 umschäumt ist.FIG. 2 shows an overheated cable, which is foamed by insulating material 4 in area 3 .

Funktionsfähig gebliebene Kabel sind in 5 dargestellt.Functional residual cables are shown in Fig.5.

1. Brandschutz für Notstrom-Kabelkanäle, dadurch gekennzeichnet, daß bei einer Erhitzung eines einzelnen Kabels das dämmschichtbildende Material dieses Kabel alleine um­ schäumt, wobei die Funktion der anderen Kabel erhalten bleibt.1. Fire protection for emergency power cable ducts, characterized in that when a single cable is heated, the insulating layer-forming material foams this cable alone, with the function of the other cables being retained. 2. Brandschutz für Notstrom-Kabelkanäle, dadurch gekennzeichnet, daß ein doppelter Brandschutz dadurch ge­ geben ist, daß der Kanal als solcher Brandschutz von außen bietet und bei Brandeinwirkung von außen sich erhitzt und infolge dessen innen der weitere Brandschutz durch Auslösung des Aufschäumens des dämmschichtbildenden Materials für jedes einzelne Kabel zusätz­ lich schutzbringend wirkt.2. Fire protection for emergency power cable ducts, characterized in that a double fire protection ge is that the channel as such provides fire protection from the outside and in the event of fire from the outside heats up and as a result inside the further fire protection by triggering the foaming of the additional insulating material for each individual cable has a protective effect. 3. Brandschutz für Notstrom-Kabelkanäle, dadurch gekennzeichnet, daß durch die Verlängerung des Kabelkanals auf mehrere Meter viele kleine Wandabschottungen erspart werden.3. Fire protection for emergency power cable ducts, characterized in that by the extension of the cable duct many small wall partitions can be saved on several meters.
