Description

Die Erfindung betrifft einen Rauchschutzabschluß zum rauchdichten Verschließen von Öffnungen in Wänden und/oder Decken, insbesondere für durch Transportschienen verbundene Räume, mit einem parallel zur Wand oder Decke verschiebbaren Schieber.The invention relates to a smoke protection closure for the smoke-tight sealing of openings in walls and / or ceilings, in particular for rooms connected by transport rails, with a slide that can be moved parallel to the wall or ceiling.

Feuerschutzabschlüsse zum Verschließen von Öffnungen in Brandabschnitttrennungen sind allgemein bekannt.Fire barriers for closing openings in fire compartment partitions are generally known.

Bei mit Transportschienen verbundenen Räumen wird dabei entweder ein Stück der Transportschiene aus dem Verschiebeweg eines Schiebers entfernt oder es ist von vornherein eine Lücke im Transportweg vorgesehen, so daß im Brandfalle ein Schieber vor die Offnung geschoben werden kann, wodurch ein feuerdichter Abschluß entsteht. Derartige Feuerschutzabschlüsse müssen nach den bestehenden Vorschriften nicht rauchdicht sein. Es hat sich aber gezeigt, daß der vor dem eigentlichen Feuer entstehende Rauch bzw. während des Brandfalles auftretende Rauch die Brandsituation stark beeinflußt.In the case of rooms connected to transport rails, either a piece of the transport rail is removed from the displacement path of a slide or a gap is provided in the transport route from the outset, so that a slide can be pushed in front of the opening in the event of a fire, resulting in a fire-proof closure. Such fire barriers do not have to be smoke-tight according to the existing regulations. However, it has been shown that the smoke that arises in front of the actual fire or smoke that arises during the fire has a strong influence on the fire situation.

Aus der DE-U 8 118 678 ist ein Brandschutz-Schiebetor bekannt, das ein mittels Laufwagen an einer Laufschiene aufgehängtes und längs der Laufschiene verschiebbares Torblatt aufweist. An der die mit dem Brandschutztor abschließenden Öffnung umgebenden Wand sind umlaufende Winkelprofile befestigt, die mit Dichtwinkeln zusammenwirken und im geschlossenen Zustand des Brandschutzschiebetores eine umlaufende labyrinthdichtungsähnliche Abdichtung gegenüber der Wand bilden.From DE-U 8 118 678 a fire protection sliding door is known which has a door leaf suspended from a running rail by means of carriages and displaceable along the running rail. Circumferential angle profiles are attached to the wall surrounding the opening with the fire protection door, which cooperate with sealing brackets and form a circumferential labyrinth seal-like seal against the wall when the fire protection sliding gate is closed.

Die Dichtwinkel sind mit zusätzlichen, unter Hitzeeinwirkung aufblähbaren Dichtstreifen versehen.The sealing brackets are provided with additional sealing strips that can be inflated under the influence of heat.

Die Dichtstreifen werden durch aufspritzbare Metallprofile abgedeckt.The sealing strips are covered by sprayable metal profiles.

Die DE-U 7 026 108 beschreibt eine feuerhemmende Abschlußtür mit beidseitig an einem Rahmen befestigten Deckplatten und mit einem den Hohlraum zwischen den Deckplatten und dem Rahmen ausfüllenden Plattenmaterial. Der Rahmen besteht dabei aus einem Papiergips, der an seinen Stimflächen mit einem Kunststoffprofil abgedeckt ist, das bei erhöhter Temperatur im Volumen zunimmt.DE-U 7 026 108 describes a fire-retardant end door with cover plates attached to both sides of a frame and with a plate material filling the cavity between the cover plates and the frame. The frame consists of a paper plaster that is covered on its end faces with a plastic profile that increases in volume at elevated temperatures.

Der Erfindung liegt die Aufgabe zugrunde, einen Rauchabschluß gemäß dem Oberbegriff des Hauptanspruchs zu schaffen, der bei einer vereinfachten Konstruktion Öffnungen in Wänden oder Decken bei erhöhter Temperatur rauchdicht verschließt.The invention has for its object to provide a smoke barrier according to the preamble of the main claim, which closes smoke-tight openings in a simplified construction in walls or ceilings at elevated temperature.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Hauptanspruchs in Verbindung mit den Merkmalen des Oberbegriffs gelöst. Erfindungsgemäß ist ein Schieber vorgesehen, der in Gleitführungen geführt ist, wobei jede Gleitführung aus einem Metallprofil und einer Schiebeleiste besteht, die gegeneinander verschiebbar sind. Die Schiebeleiste besteht aus einem Kunststoff, der bei erhöhter Temperatur aufquillt, so daß die Rauchgase, die eine Temperatur von 2000 C und darüber erreichen können, nicht durch die Öffnung treten können. Laut Verordnung ist ein Grenzwert für den Rauchdurchtritt von 10 Norm m3 Rauchgas bei 50 Pa vorgegeben, mit der vorliegenden Erfindung wird dieser Grenzwert weit unterschritten. Gemäß der Erfindung hat somit die Gleitführung zwei Funktionen; sie dient gleichzeitig als Lagerung des Schiebers selbst und als Rauchabdichtung. Besonders vorteilhaft ist weiterhin, daß sich der Kunststoff beim Erkalten wieder zurückbildet, so daß sich der Rauchschutzabschluß nach Temperatursenkung wieder öffnen läßt.This object is achieved according to the invention by the characterizing features of the main claim in conjunction with the features of the preamble. According to the invention, a slide is provided which is guided in slide guides, each slide guide consisting of a metal profile and a slide bar which can be displaced relative to one another. The sliding bar is made of a plastic that swells at an elevated temperature so that the flue gases, which can reach a temperature of 2000 C and above, cannot pass through the opening. According to the ordinance, a limit value for the passage of smoke of 10 standard m3 of flue gas at 50 Pa is specified. According to the invention, the sliding guide thus has two functions; it also serves as a bearing for the slide itself and as a smoke seal. It is also particularly advantageous that the plastic regresses when it cools down, so that the smoke protection cover can be opened again after the temperature has dropped.

Durch die in den Unteransprüchen angegebenen Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des Gegenstandes des Hauptanspruchs möglich.Advantageous further developments and improvements of the subject matter of the main claim are possible through the measures specified in the subclaims.

Die Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert. Es zeigen

The invention is illustrated in the drawing and is explained in more detail in the description below. Show it
  • 1 is a view of the smoke protection closure according to the invention,
  • 2 shows a section along the section lines AA according to FIG. 1,
  • Fig. 3 shows a section along the section lines BB of FIG. 1 and
  • Fig. 4 shows a section in an enlarged view through a sliding guide.

Entsprechend den Fig. 1 bis 3 weist der Rauchschutzabschluß einen Rahmen 1 beispielsweise aus Stahlblech auf, der mittels Befestigungswinkeln 2 an der die Öffnung 3 aufweisenden Wand oder Decke 4 befestigt ist. In dem Stahlrahmen ist mittels Gleitführungen 5 ein Schieber 6 geführt, der im normalen Betriebszustand geöffnet ist. Durch die Öffnung 3 hindurch führen Transportschienen, die quer oder senkrecht zur Schließrichtung des Schiebers 6 angeordnet sein können. Bei dem beschriebenen Ausführungsbeispiel ist in den Transportschienen 7 eine Lücke 8 vorgesehen, durch die das Schieberblatt 6 hindurchgreift. Selbstverständlich können die Transport schienen auch derart ausgebildet sein, daß sie im Verschiebeweg des Schiebers 6 ein entfernbares Stück aufweisen, das mit der Bewegung des Schiebers 6 aus seinem Verschiebeweg entfernt wird.1 to 3, the smoke protection cover has a frame 1, for example made of sheet steel, which is fastened by means of fastening angles 2 to the wall or ceiling 4 having the opening 3. A slide 6 is guided in the steel frame by means of slide guides 5 and is open in the normal operating state. Transport rails, which can be arranged transversely or perpendicular to the closing direction of the slide 6, pass through the opening 3. In the described embodiment, a gap 8 is provided in the transport rails 7, through which the slide blade 6 extends. Of course, the transport rails can also be designed such that they have a removable piece in the displacement path of the slide 6, which is removed from its displacement path with the movement of the slide 6.

Zur Bewegung des Schiebers 6 ist eine Antriebseinheit vorgesehen, die einen Antriebsmotor 9, ein Getriebe 10 und eine Rutschkupplung 11 aufweist. Der Motor 9 treibt über das Getriebe 10 und die Kupplung 11 einen Antriebshebei 12 auf, dessen Ende mit einer Ablaufrolle 13 fest verbunden ist, die in einer an dem Schieber 6 befestigten Führungsschiene 15 läuft. Die Offenstellung des Schiebers 6 ist durch die gestrichelten Linien angegeben, wobei die Schwenkbewegung des Antriebshebels 12 durch den gestrichelten Halbkreis dargestellt ist. Zur Abstützung der Antriebseinheit ist eine Stütze 16 vorgesehen.To move the slide 6, a drive unit is provided, which has a drive motor 9, a gear 10 and a slip clutch 11. The motor 9 drives a drive lever 12 via the transmission 10 and the clutch 11, the end of which is firmly connected to a run-off roller 13 which runs in a guide rail 15 fastened to the slide 6. The open position of the slide 6 is indicated by the dashed lines, the pivoting movement of the drive lever 12 being represented by the dashed semicircle. A support 16 is provided to support the drive unit.

In Fig. 4 ist in vergrößerter Ansicht ein Schnitt durch die Gleitführung 5 dargestellt, die den Schieber 6 entsprechend Fig. 1 oben und unten führen. Die Gleitführung besteht aus einem ersten Metallprofil 17, das U-förmig ausgebildet ist und das mit den Befestigungswinkeln 2 verbunden ist. An dem ersten Metallprofil 17 ist über Schrauben längs des Rahmens 1 ein zweites, im Querschnitt C-förmiges Metallprofil 19 befestigt. Der Schieber 6 ist ebenfalls über Schrauben 20 am oberen und unteren Ende mit einer Schiebeleiste 21 verbunden, die an das Profil des zweiten Metallprofils 19 angepaßt ist, das heißt sie hat einen im wesentlichen rechteckigen Querschnitt und ist mit seitlichen Einschnitten versehen, in die die Schenkel 22 des C-Profils eingreifen und die Schiebeleiste führen. Die Schiebeleiste ist in dem Metallprofil 19 frei verschiebbar, wobei trotzdem der Schieber 6 sicher gelagert ist.In Fig. 4 is an enlarged view of a section through the sliding guide 5, which guide the slide 6 according to Fig. 1 above and below. The sliding guide consists of a first metal profile 17 which is U-shaped and which is connected to the mounting brackets 2. On the first metal profile 17 is along the screws Frame 1 attached a second, in cross-section C-shaped metal profile 19. The slider 6 is also connected by screws 20 at the upper and lower ends to a sliding bar 21 which is adapted to the profile of the second metal profile 19, that is to say it has a substantially rectangular cross section and is provided with lateral incisions into which the legs Intervene 22 of the C-profile and guide the sliding bar. The sliding bar is freely displaceable in the metal profile 19, the slider 6 nevertheless being securely mounted.

Die Schiebeleiste 21 besteht aus einem Kunststoff, zum Beispiel einem Niederdruckpolyäthylen, das die Eigenschaft hat, bei erhöhter Temperatur aufzuquellen. Treten aufgrund eines schwelendes Brandes oder dergleichen erhöhte Temperaturen auf, so dehnt sich der Kunststoff aus, so daß der durch Abrieb gebildete und zur ungehinderten Verschiebbarkeit notwendige Raum zwischen Metallprofil 19 und Schiebeleiste 21 ausgefüllt wird. Somit wird die Gleitführung 5 abgedichtet, so daß kein Rauch zwischen Schieber 6 und Gleitführung 5 hindurchgelangen kann. Wenn die Temperaturen sinken, bildet sich der Kunststoff der Schiebeleiste 21 zurück, so daß der Schieber 6 wieder geöffnet werden kann.The slide bar 21 is made of a plastic, for example a low-pressure polyethylene, which has the property of swelling at an elevated temperature. If increased temperatures occur due to a smoldering fire or the like, the plastic expands so that the space formed by abrasion and necessary for unimpeded displaceability is filled between the metal profile 19 and the sliding strip 21. Thus, the slide guide 5 is sealed so that no smoke can get between the slide 6 and slide guide 5. When the temperatures drop, the plastic of the slide bar 21 reforms so that the slide 6 can be opened again.

Auch seitlich ist, wie in Fig. 2 gezeigt ist, der Schieber 6 abgedichtet,und zwar durch Gummileisten 23, 24, die einerseits links von der Öffnung an einem Vierkantrohr 25 befestigt und andererseits rechts von der Öffnung 3 mittels einer Leiste 26 und den Befestigungswinkeln 2 befestigt sind. Der Schieber 6 stößt in geschlossenem Zustand rechts auf die Dichtung 24 und umgreift links die Dichtung 23, wie durch den leichten Winkel des Schiebers 6 angedeutet ist.Also on the side, as shown in Fig. 2, the slide 6 is sealed, namely by rubber strips 23, 24, which are attached on the one hand to the left of the opening on a square tube 25 and on the other hand to the right of the opening 3 by means of a strip 26 and the fastening angles 2 are attached. In the closed state, the slide 6 strikes the seal 24 on the right and engages around the seal 23 on the left, as indicated by the slight angle of the slide 6.

Im Falle eines Brandes werden erhöhte Temperaturen und/oder der auftretende Rauch von einer als Temperatursensor oder Rauchmelder oder dergleichen ausgebildeten Sensoreinheit erfaßt und ein Signal wird an die Antriebseinheit abgegeben, die ein Schließen des Schiebers bewirkt. Die Schiebeleiter 21 quillt aufgrund erhöhter Temperaturen auf und dichtet den Schieber 6 ab, so daß kein Rauch mehr durch den Rauchschutzabschluß treten kann. Nach Abkühlung, sei es aufgrund der Beendigung des Brandes oder durch gezielte Löscharbeit mit einem kalten Medium, läßt sich der Schieber über die Antriebseinheit oder per Hand wieder öffnen. Dies war bisher ohne Gewalteinwirkung nicht möglich, so daß durch die Erfindung ein wichtiger Beitrag zu den Rettungsarbeiten der Feuerwehr geleistet wird.In the event of a fire, elevated temperatures and / or the smoke occurring are detected by a sensor unit designed as a temperature sensor or smoke detector or the like, and a signal is sent to the drive unit, which causes the slide to close. The sliding ladder 21 swells due to elevated temperatures and seals the slide 6, so that no more smoke can pass through the smoke protection cover. After cooling down, be it due to the end of the fire or through targeted extinguishing with a cold medium, the slide can be opened again using the drive unit or by hand. This was previously not possible without the use of force, so that the invention makes an important contribution to the rescue work of the fire service.
