Description

Die Erfindung betrifft einen Feuerabschluß für einen Deckendurchbruch der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a fire barrier for a ceiling opening of the type mentioned in the preamble of claim 1.

Bei einer Paternosterförderanlage bereitet die Herstellung eines Feuerabschlusses für einen Deckendurchbruch besondere Schwierigkeiten, weil die meistens als Zugmittel verwendeten Ketten mit den daran befindlichen Förderelementen wie Tragarmen und dergleichen im Brandfalle nicht einfach aufgetrennt werden können, um so den Deckendurchbruch, durch den die Paternosterförderanlage verläuft, ohne Schwierigkeiten schließen zu können.In the case of a paternoster conveyor system, the manufacture of a fire closure for a ceiling breakthrough is particularly difficult because the chains mostly used as traction means with the conveyor elements attached to them, such as support arms and the like, cannot simply be broken in the event of a fire, in order to avoid the ceiling breakthrough through which the paternoster conveyor system runs To be able to close difficulties.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Feuerabschluß der betreffenden Art zu schaffen, der einfach und sicher im Aufbau und ohne Unterbrechung einer Paternosterförderaniage im Brandfalle in der Lage ist, einen Deckendurchbruch, durch den die Paternosterförderaniage verläuft, sicher zu schließen.The invention is therefore based on the object to provide a fire closure of the type in question, which is simple and safe in the construction and without interruption of a paternoster conveyor system in the event of fire in a position to safely close a ceiling opening through which the paternoster conveyor system runs.

Die der Erfindung zugrundeliegende Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebene Lehre gelöst.The object on which the invention is based is achieved by the teaching specified in the characterizing part of claim 1.

Nach dieser Lehre ist der den Deckendurchbruch verschließende Schieber so gestaltet, daß er im geschlossenen Zustand die Zugmittel, z. B. Ketten, der Paternosterförderanlage umschließt, so daß es nicht erforderlich ist, komplizierte mehrteilige Schieber einzusetzen.According to this teaching, the slider closing the ceiling opening is designed in such a way that, when closed, the traction means, e.g. B. chains, the paternoster conveyor encloses so that it is not necessary to use complicated multi-part slide.

Gemäß der Lehre des Anspruchs 2 ist eine Blende aus feuerwiderstandsfähigem Material vorgesehen, die den Zweck hat, alle die Teile des Deckendurchbruchs im Brandfalle ständig geschlossen zu halten, die bereits beim Betrieb geschlossen sein können. Der den Deckendurchbruch verschließende Schieber kann sich somit im Brandfalle bündig gegen diese Blende legen, so daß eine gute Abdichtung erzielt ist. Besonders zweckmäßig ist es dabei, daß die Blende aus feuerwiderstandsfähigem Material Teile, insbesondere Fortsätze aufweist, die bei geschlossenem Schieber in die Schlitze in dem Schieber eingreifen. Diese Teile oder Fortsätze der Blende können sich z. B. in den Raum zwischen den Trums der Kette der Paternosterförderanlage erstrecken, so daß im Brandfalle bei geschlossenem Schieber auch diese Bereiche völlig geschlossen sind und zwischen Schieber und Blende nur geringe Durchtritte für die Ketten verbleiben, die natürlich durch die Ketten weitgehend geschlossen sind.According to the teaching of claim 2, a panel made of fire-resistant material is provided, which has the purpose to keep all the parts of the ceiling opening in the event of a fire, which may already be closed during operation. In the event of a fire, the slider closing the ceiling opening can lay flush against this panel, so that a good seal is achieved. It is particularly expedient that the screen made of fire-resistant material has parts, in particular extensions, which engage in the slots in the slide when the slide is closed. These parts or extensions of the aperture can, for. B. extend into the space between the strands of the chain of the paternoster conveyor system, so that in the event of fire when the slide is closed, these areas are completely closed and only small passages for the chains remain between the slide and the screen, which of course are largely closed by the chains.

In jedem Fall ist es gemäß einer Weiterbildung der Erfindung zweckmäßig, daß die Ränder der Schlitze in dem Schieber und/oder der Fortsätze der Blende Dichtungsbürsten und/oder Streifen aus einem Material aufweisen, das bei Hitze aufschäumt. Hierdurch wird im Brandfalle der Zwischenbereich zwischen Schieber und Blende im geschlossenen Zustand abgedichtet, so daß auch kein Rauch hindurchströmen kann.In any case, it is expedient according to a development of the invention that the edges of the slots in the slide and / or the extensions of the panel have sealing brushes and / or strips made of a material that foams when heated. As a result, in the event of a fire, the intermediate area between the slide and the cover is sealed in the closed state, so that no smoke can flow through it.

Anhand der Zeichnung soll die Erfindung an einem Ausführungsbeispiel näher erläutert werden.

  • Fig. 1 ist eine Draufsicht auf einen Feuerabschluß für einen Deckendurchbruch einer Paternosterförderanlage mit Teilen derselben,
  • Fig. 2 ist ein Vertikalschnitt durch Fig. 1.
The invention will be explained in more detail using an exemplary embodiment with reference to the drawing.
  • 1 is a plan view of a fire barrier for a ceiling breakthrough of a paternoster conveyor system with parts thereof,
  • FIG. 2 is a vertical section through FIG. 1.

Der in den Fig. 1 und 2 gezeigte Feuerabschluß weist ein Gehäuse 1 auf, das im wesentlichen kastenförmig ist und einen Durchbruch 2 aufweist, durch die sich zur Verdeutlichung der Verwendung des Feuerabschlusses in der Zeichnung gezeigte drei Förderstrecken einer Paternosterförderanlage erstrecken. Die Förderstrecken sind jeweils gleich aufgebaut und weisen Holme 3 und 4 sowie Ketten 5 und 6 auf, an denen querverlaufende Tragarme 7 befestigt sind und die sich jeweils auf gleicher Höhe befinden, so daß sie zwischen sich eine hier beispielsweise als Fördergut gezeichnete Blechtafel 8 tragen können.The fire closure shown in FIGS. 1 and 2 has a housing 1 which is essentially box-shaped and has an opening 2, through which three conveying lines of a paternoster conveyor system extend to illustrate the use of the fire closure in the drawing. The conveyor lines are each constructed identically and have spars 3 and 4 and chains 5 and 6, on which transverse support arms 7 are attached and which are each at the same height, so that they can carry a sheet 8 drawn here, for example, as a material to be conveyed .

In dem Gehäuse 1 ist ein Schieber 9 angeordnet, der an seinen Längskanten 10 und 11 jeweils Rollen 12 und 13 aufweist, die auf Führungsschienen 14 und 15 laufen, so daß der Schieber aus der in der Zeichnung gezeigten Offenstellung nach links in eine geschlossene Stellung bewegbar ist. Diese Bewegung erfolgt im Brandfalle mittels Seilen 16 und 17, die seitlich an den Längskanten des Schiebers 9 angreifen und auf Rollen 18 und 19 geführt sind, die durch in der Zeichnung nicht gezeigte Federn in Aufwickelrichtung vorgespannt sind. Außerdem ist als Verriegelungsmittel ein Haltemagnet 20 vorgesehen, der den Schieber 9 entgegen der Kraft der Seile 16 und 17 bzw. der Federn in den Rollen 18 und 19 geöffnet hält und im Brandfalle so betätigt wird, daß der Schieber freigegeben und in Schließstellung gezogen werden kann.In the housing 1, a slide 9 is arranged, which on its longitudinal edges 10 and 11 each have rollers 12 and 13 which run on guide rails 14 and 15, so that the slide can be moved from the open position shown in the drawing to the left into a closed position is. In the event of a fire, this movement takes place by means of ropes 16 and 17 which engage laterally on the longitudinal edges of the slide 9 and are guided on rollers 18 and 19 which are biased in the winding direction by springs, not shown in the drawing. In addition, a holding magnet 20 is provided as a locking means, which keeps the slide 9 open against the force of the cables 16 and 17 or the springs in the rollers 18 and 19 and is actuated in the event of fire so that the slide can be released and pulled into the closed position .

In dem Schieber 9 befinden sich Sackschlitze 21 und 22, deren Breite etwa der Breite der Holme 3 entspricht, so daß die Ränder der Schlitze 21 und 22 in Schließlage des Schiebers 9 die Holme 3 und 4 umgreifen.In the slider 9 there are pocket slots 21 and 22, the width of which corresponds approximately to the width of the bars 3, so that the edges of the slots 21 and 22 encompass the bars 3 and 4 in the closed position of the slide 9.

Gegenüber dem Schieber 9 ist eine Blende 23 angeordnet, die ebenso wie der Schieber 9 aus feuerwiderstandsfähigem Material besteht und deren vordere Kante 24 komplementär zu einer vorderen Kante 25 des Schiebers 9 ausgebildet ist, so daß ein dichter Abschluß erzielt wird. Es ist zu erkennen, daß ein mittleres Teil 26 des Schiebers länger ist als die äußeren Teile 27 und 28. Entsprechend erstrecken sich äußere Teile 29 und 30 der Kante 24 der Blende 23 weiter nach vorn, sie stoßen bündig gegen die Holme 4 der in der Fig. 1 oben und unten gezeigten Förderstrecken, so daß kein freier Zwischenraum verbleibt. Gleichzeitig erstrecken sich Teile 31 und 32 der Blende 23 zwischen den Holmen 3 und 4, so daß auch dieser Raum, der von dem Schieber 9 nicht geschlossen werden kann, im Brandfalle völlig geschlossen ist.Opposite the slide 9, a diaphragm 23 is arranged which, like the slide 9, is made of fire-resistant material and whose front edge 24 is complementary to a front edge 25 of the slide 9, so that a tight seal is achieved. It can be seen that a central part 26 of the slider is longer than the outer parts 27 and 28. Accordingly, outer parts 29 and 30 of the edge 24 of the panel 23 extend further forward, they abut the spars 4 of the in the Fig. 1 shown above and below conveyor lines, so that no free space remains. At the same time, parts 31 and 32 of the panel 23 extend between the bars 3 and 4, so that this space, which cannot be closed by the slide 9, is completely closed in the event of a fire.

Die Ränder der Schlitze 21 und 22 sind mit durch gestrichelte Linien angedeuteten Streifen 33 und 34 aus einem Material belegt, das im Brandfalle aufschäumt und so die unvermeidlichen Schließspalte zwischen Blende und Schieber dicht verschließt. Im Bereich der in der Fig. 1 links gezeigten Förderstrecke der Paternosterförderanlage erstreckt sich ein Teil 35 der Blende 23 zwischen den Holmen 3 und 4, und außerdem sind Streifen 36 und 37 aus einem Material, das im Brandfalle aufschäumt, hinter den Holen 3 und 4 angeordnet, so daß auch dieser Bereich feuer-und rauchdicht abgeschlossen ist.The edges of the slots 21 and 22 are with stripes indicated by dashed lines 33 and 34 made of a material that foams up in the event of a fire and thus tightly seals the inevitable closing gaps between the panel and slide. In the area of the conveyor section of the paternoster conveyor system shown on the left in FIG. 1, part 35 of the panel 23 extends between the bars 3 and 4, and strips 36 and 37 made of a material that foams up in the event of fire are behind the bars 3 and 4 arranged so that this area is also fire and smoke-tight.
