Description

Die Erfindung betrifft einen Feuerabschluß der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a fire closure of the type mentioned in the preamble of claim 1.

Durch die DE-GMS 83 13 824 ist ein Feuerschutzabschluß der betreffenden Art bekannt, bei dem der Schieber vollständig aus feuerwiderstandsfähigem Material besteht. Der Schieber ist verhältnismäßig dick, und das Material des Schiebers ist so beschaffen, daß die in Schließrichtung vorn liegende Kante den Konturen der durch den Durchbruch hindurchführenden Fördermittel nur schlecht anpaßbar ist. Zwar ist auch bereits die Verwendung von Material vorgesehen, das bei Hitze aufschäumt und unvermeidliche Zwischenräume zwischen Schieber und Fördermitteln verschließt, jedoch kann dieses Material durch die unvermeidlichen Zwischenräume entweichen. Das für den Schieber verwendete Material ist außerdem spröde, so daß die Gefahr von Beschädigungen der in Schließrichtung vorn liegenden Kante bei häufigem Schließen des Schiebers durch Anstoßen an die r Anschlagkante besteht.From DE-GMS 83 13 824 a fire protection closure of the type in question is known, in which the slide is made entirely of fire-resistant material. The slider is relatively thick, and the material of the slider is such that the edge lying in the front in the closing direction is difficult to adapt to the contours of the conveying means passing through the opening. Although the use of material which foams up in the heat and closes inevitable gaps between slide and conveying means is already provided, this material can escape through the inevitable gaps. The material used for the slide is also brittle, so that there is a risk of damage to the front edge in the closing direction if the slide is closed frequently by bumping against the r stop edge.

Der Erfindung liegt die Aufgabe zugrunde, einen Feuerschutzabschluß der betreffenden Art zu schaffen, der eine gute Abdichtung auch bei komplizierten Formen der durch den Durchbruch in dem Feuerschutzabschluß hindurchführenden Fördermittel, z.B. Förderschienen, ermöglicht, ein Entweichen des bei Hitze aufschäumenden Materials vermeidet, robust bei häufigem Gebrauch und darüber hinaus einfach und billig in der Konstruktion ist.The invention has for its object to provide a fire protection closure of the type in question, which allows a good seal even with complicated shapes of the conveying means leading through the opening in the fire protection closure, for example conveying rails, to prevent the heat-foaming material from escaping, robust with frequent use Use and moreover easy and cheap in the construction is.

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.

Die Erfindung beruht auf dem Grundgedanken, den in Schließrichtung vorn liegenden Bereich des Schiebers nicht wie bisher bis zur Anschlagkante hin aus feuerwiderstandsfähigem Material auszubilden, sondern durch im Abstand zueinander angeordnete Bleche, die im Brandfall für kurze Zeit bereits einen Feuerwiderstand darstellen. Diese Bleche lassen sich in einfacher und vorteilhafter Weise an komplizierte Konturen der durch den Durchbruch hindurchgehenden Fördermittel anpassen. Die hinsichtlich des Feuerwiderstandes langzeitige Abdichtung erfolgt nach dem Grundgedanken der Erfindung vollständig durch Material, das bei Hitze aufschäumt und dann einen Feuerwiderstand bildet. Der von diesem Material abzuschottende Raum ist zwar verhältnismäßig groß, jedoch sorgen die den Aufschäumraum begrenzenden Bleche dafür, daß der Schaum gefangen ist und nicht entweichen kann.The invention is based on the basic idea that the area of the slide located in the front in the closing direction should not be made of fire-resistant material up to the stop edge as before, but by spaced-apart metal sheets which in the event of fire already represent fire resistance for a short time. These sheets can be adapted in a simple and advantageous manner to complicated contours of the conveying means passing through the opening. The long-term sealing with regard to fire resistance takes place completely according to the basic idea of the invention by material which foams when heated and then forms a fire resistance. Although the space to be partitioned off from this material is relatively large, the metal sheets delimiting the foaming space ensure that the foam is trapped and cannot escape.

Da die erfindungsgemäßen Bleche verhältnismäßig dünn sein können, ist es sogar möglich, gemäß einer Weiterbildung der Erfindung die Fördermittel durch einen engen Spalt zu unterbrechen, der den Förderbetrieb nicht hindert, jedoch das Eintreten der Bleche ermöglicht. Auf diese Weise ist es überhaupt nicht mehr erforderlich, die Vorderkanten der Bleche den Konturen der Fördermittel, z.B. Förderschienen, anzupassen, sie können z.B. immer eine gerade Vorderkante haben, die den Raum zwischen den Blechen in hohem Maße abdichtet und damit ein Entweichen von Material, das bei Hitze aufschäumt, weitgehend vermeidet.Since the sheets according to the invention can be relatively thin, it is even possible, according to a further development of the invention, to interrupt the conveying means by means of a narrow gap which does not hinder the conveying operation, but which enables the sheets to enter. In this way, it is no longer necessary at all to align the front edges of the sheets with the contours of the conveying means, e.g. Conveyor rails, to adapt, e.g. Always have a straight front edge that seals the space between the sheets to a large extent and thus largely prevents the escape of material that foams up when heated.

Die Weiterbildung der Erfindung gemäß Anspruch 5 sieht zusätzliches Material im Bereich der Anschlagkante des Durchbruchs in dem Gehäuse für den Schieber vor, so daß bei Hitze aufschäumendes Material von zwei Seiten her den Raum zwischen den erfindungsgemäßen Blechen ausfüllt.The development of the invention according to claim 5 provides additional material in the region of the stop edge of the opening in the housing for the slide, so that when material foams in heat fills the space between the sheets according to the invention from two sides.

Der in den Fig. 1 bis 3 dargestellte Feuerschutzabschluß weist ein Gehäuse 1 auf, das, wie in den Fig. 2 und 3 dargestellt, an einer Wand 2 im Bereich eines Wanddurchbruchs 3 angebracht ist, derart, daß ein Durchbruch 4 in dem Gehäuse 1 mit dem Wanddurchbruch fluchtet.The fire protection closure shown in FIGS. 1 to 3 has a housing 1 which, as shown in FIGS. 2 and 3, is attached to a wall 2 in the region of a wall opening 3 in such a way that an opening 4 in the housing 1 aligned with the wall opening.

In dem Gehäuse 1 befindet sich ein Schieber 5, der in dem Gehäuse 1 geführt ist. Im geöffneten Zustand, der in der Zeichnung nicht gezeigt ist, hängt der Schieber 5 mit einer Eisenplatte 6 an einem Magneten 7. Im Brandfall wird diese Verbindung gelöst, so daß der Schieber 5 sich herunterbewegt und den Durchbruch 4 und damit auch den Wanddurchbruch 3 schließt. Zur allgemeinen Betätigung des Schiebers 5 ist ein Antriebsmotor 8 vorgesehen, der über ein Gestänge 9 eine Betätigung des Schiebers 5 gestattet.In the housing 1 there is a slide 5 which is guided in the housing 1. In the open state, which is not shown in the drawing, the slide 5 hangs with an iron plate 6 on a magnet 7. In the event of fire, this connection is released, so that the slide 5 moves down and the opening 4 and thus also the wall opening 3 closes . For general actuation of the slide 5, a drive motor 8 is provided, which allows the slide 5 to be actuated via a linkage 9.

Durch den Wanddurchbruch 3 und den Durchbruch 4 führen Förderschienen 10 und 11 der Förderanlage. WieThrough the wall opening 3 and the opening 4, conveyor rails 10 and 11 of the conveyor system. How

Wie aus der Fig. 4 zu ersehen ist, die eine vergrößerte Einzelheit aus dem unteren Bereich der Fig. 2 zeigt, befinden sich auf den Außenflächen des Schiebers 5 Bleche 12 und 13, die die gesamten Außenflächen des Schiebers 5 überdecken und über eine Unterkante 14 nach unten vorstehen und mit unteren Rändern gegen eine Anschlagkante 15 anstoßen, so daß in dem gezeigten geschlossenen Zustand des Feuerschutzabschlusses ein geschlossener Raum zwischen den Blechen 12 und 13 sowie der Unterkante 14 des Schiebers 5 und der Oberkante 15 des Gehäuses 1 gebildet ist. In diesem Raum befindet sich unmittelbar unter der unteren Kante 14 des Schiebers 5 Masse 16 aus einem Material, das bei Hitze aufschäumt. Außerdem befindet sich entsprechend bei Hitze aufschäumende Masse 17 auf der Anschlagkante 15 im Bereich zwischen den Blechen 12 und 13.As can be seen from FIG. 4, which shows an enlarged detail from the lower area of FIG. 2, there are 5 plates 12 and 13 on the outer surfaces of the slide, which cover the entire outer surfaces of the slide 5 and over a lower edge 14 protrude downwards and abut with a lower edge against a stop edge 15, so that in the closed state of the fire protection closure shown, a closed space is formed between the sheets 12 and 13 and the lower edge 14 of the slide 5 and the upper edge 15 of the housing 1. In this room, mass 16 is located directly below the lower edge 14 of the slide 5 made of a material that foams when hot. In addition, there is correspondingly foaming mass 17 in the heat on the stop edge 15 in the area between the sheets 12 and 13.

Die Menge der Massen 16 und 17 ist so bemessen, daß im Brandfall der gesamte Innenraum zwischen den Blechen 12 und 13 mit aufgeschäumter und feuerhemmender Masse gefüllt ist.The amount of the masses 16 and 17 is such that in the event of a fire the entire interior between the sheets 12 and 13 is filled with foamed and fire-retardant mass.

Das Gehäuse 1 und der Schieber 5 sind aus Platten 18, 19 und 20 sowie 21 und 22 aufgebaut, die durch Blechprofile 23 und 24 miteinander verbunden sind.The housing 1 and the slide 5 are constructed from plates 18, 19 and 20 and 21 and 22, which are connected to one another by sheet metal profiles 23 and 24.

Fig. 4 zeigt deutlich, daß die Förderschiene 11 durch schmale Schlitze 25 und 26 unterbrochen ist, durch die sich die Bleche 12 und 13 hindurcherstrecken. Die Förderschiene 11 beeinträchtigt also nicht die Abschottung im Brandfall und insbesondere nicht die Abdichtung des Innenraumes zwischen den Blechen 12 und 13. Andererseits stören die schmalen Schlitze 25 und 26 nicht die Funktion der Förderschiene 11.Fig. 4 clearly shows that the conveyor rail 11 is interrupted by narrow slots 25 and 26 through which the sheets 12 and 13 extend. The conveyor rail 11 therefore does not impair the partitioning in the event of a fire and in particular does not affect the sealing of the interior between the sheets 12 and 13. On the other hand, the narrow slots 25 and 26 do not interfere with the function of the conveyor rail 11.

Fig. 5 zeigt eine Abwandlung des Details gemäß Fig. 4, wobei der Schnitt senkrecht zu der Darstellung in Fig. 4 verläuft. Sich entsprechende Teile sind mit gleichen Bezugszeichen versehen. Zwischen den Rändern des Durchbruchs in der Wand 2 verlaufen Förderschienen 27 und 28, die durch ein gemeinsames Teil 29 miteinander verbunden sind. Auf diesem Teil 29 befinden sich eine Zahnstange 30 sowie Stromschienen 31. An den Seiten befinden sich Führungsschienen 32 und 33. Außerdem sind Förderschienen 34 und 35 vorgesehen. Die abschottenden Bleche 12 und 13 wie in Fig. 4 sind in dieser Darstellung nicht zu erkennen.FIG. 5 shows a modification of the detail according to FIG. 4, the section running perpendicular to the illustration in FIG. 4. Corresponding parts are provided with the same reference symbols. Conveyor rails 27 and 28 run between the edges of the opening in the wall 2 and are connected to one another by a common part 29. On this part 29 there are a rack 30 and busbars 31. On the sides there are guide rails 32 and 33. In addition, conveyor rails 34 and 35 are provided. The partitioning plates 12 and 13 as in FIG. 4 cannot be seen in this illustration.

Die bei Hitze aufschäumenden Massen sind in aufgeschäumtem Zustand gezeigt. Dabei ist zu erkennen, daß im seitlichen Bereich zwischen den Förderschienen 27 und 34 bzw. 28 und 35 zusätzliche Massen 36 bis 39 vorgesehen sind, die für eine gute Ausfüllung des Abschottungsraumes sorgen. Die Bleche 12 und 13 erstrecken sich durch Schlitze in den Förderschienen 34 und 35, so daß der Gesamtraum abgedichtet ist und kein aufschäumendes Material austreten kann.The masses foaming in the heat are shown in the foamed state. It can be seen that additional masses 36 to 39 are provided in the lateral area between the conveyor rails 27 and 34 or 28 and 35, which ensure good filling of the partitioning space. The sheets 12 and 13 extend through slots in the conveyor rails 34 and 35, so that the entire space is sealed and no foaming material can escape.
