Description

Die Erfindung betrifft einen Entrauchungskanal, insbesondere einen solchen der Feuerwiderstandsklasse L90.The invention relates to a smoke extraction duct, in particular one of the fire resistance class L90.

Entrauchungsanlagen im Allgemeinen sowie Entrauchungskanäle als Teil solcher Entrauchungsanlagen im Speziellen sind aus dem Stand der Technik an sich gut bekannt, weshalb es eines gesonderten druckschriftlichen Nachweises an dieser Stelle nicht bedarf.Smoke extraction systems in general and smoke extraction ducts as part of such smoke extraction systems in particular are well known from the prior art, which is why a separate documentary proof at this point is not required.

Bei Bränden entstehen Rauch und je nach Brandgut darüber hinaus unter Umständen auch giftige Gase. Diese können zum einen lebensbedrohlich sein sowie zum anderen die freie Sicht behindern, weshalb insbesondere Rettungswege von entsprechenden Gasen und/oder Rauch freizuhalten sind. Entrauchungsanlagen dienen dem Abzug von Gasen und/oder Rauch, wobei entsprechende Entrauchungskanäle vorgesehen sind, über die Gase und/oder Rauch vom Brandort ins Freie geleitet werden kann.Fires may produce smoke and, depending on the type of combustible material, may also contain toxic gases. On the one hand, these can be life-threatening and, on the other hand, obstruct the unobstructed view, which is why, in particular, escape routes are to be kept free of corresponding gases and / or smoke. Smoke extraction systems are used for the extraction of gases and / or smoke, with appropriate smoke extraction channels are provided, can be passed through the gases and / or smoke from the fire to the outside.

Aus der DE3013400 A1 ist ein feuerbeständiger Kanal bekannt, welcher die Merkmale der Präambel aufweist. Aus der DE2841651 A1 ist ein ähnlicher Kanal bekannt.From the DE3013400 A1 For example, a fire-resistant channel is known which has the features of the preamble. From the DE2841651 A1 a similar channel is known.

Aus dem Stand der Technik bekannte Entrauchungskanäle haben sich im alltäglichen Praxiseinsatz bewährt. Es besteht gleichwohl Verbesserungsbedarf, insbesondere mit Blick auf einen noch effizienteren Gas- und/oder Rauchabtransport. Es ist deshalb die Aufgabe der Erfindung, einen gegenüber dem Stand der Technik neuartigen Entrauchungskanal vorzuschlagen.From the prior art known smoke control channels have proven themselves in everyday practical use. There is nevertheless room for improvement, especially with regard to even more efficient gas and / or smoke removal. It is therefore the object of the invention to provide a comparison with the prior art novel Entrauchungskanal.

Zu Lösung dieser Aufgabe wird mit der Erfindung vorgeschlagen ein Entrauchungskanal mit einer Innenwandung und einer davon unter Ausbildung eines Spaltraums beabstandeten Außenwandung, wobei die Innenwandung und die Außenwandung jeweils aus Calciumsilikat gebildet sind, und mit einem im Spaltraum angeordneten Traggerüst, das aus Hohlprofilen aus Stahl gebildet ist, sowie mit im Spaltraum angeordneten Streifen aus Calciumsilikat, mit denen die Innenwandung und die Außenwandung mechanisch verbunden sind.To solve this problem, the invention proposes a smoke extraction duct with an inner wall and one of them, forming a gap spaced outer wall, wherein the inner wall and the outer wall are each formed of calcium silicate, and arranged in the gap space supporting framework, which is formed from hollow sections of steel, and arranged in the gap space strips of calcium silicate, with which the inner wall and the outer wall are mechanically connected ,

Der Entrauchungskanal nach der Erfindung ist doppelwandig ausgebildet. Er verfügt über eine Innenwandung einerseits und eine Außenwandung andererseits. Dabei sind sowohl die Innenwandung als auch die Außenwandung aus Calciumsilikat gebildet, so dass eine weitestgehende Unempfindlichkeit auch gegenüber heißen Gasen und/oder heißem Rauch gegeben ist, was eine entsprechende Feuerwiderstandsklasse sicherstellt. Bevorzugterweise sind die Innenwandung und die Außenwandung in einer solchen Dicke bemessen, dass die Feuerwiderstandsklasse L90 erreicht ist. Andere Ausgestaltungen sind hier gleichfalls denkbar, das heißt auch solche, zur Einhaltung einer höheren oder einer niedrigeren Feuerwiderstandsklasse.The smoke extraction duct according to the invention is double-walled. He has an inner wall on the one hand and an outer wall on the other. Both the inner wall and the outer wall are formed from calcium silicate, so that a substantial insensitivity to hot gases and / or hot smoke is given, which ensures a corresponding fire resistance class. Preferably, the inner wall and the outer wall are dimensioned in such a thickness that the fire resistance class L90 is reached. Other embodiments are also conceivable here, that is also those for maintaining a higher or a lower fire resistance class.

Die Innenwandung und die Außenwandung sind jeweils bevorzugterweise aus Calciumsilikat-Platten gebildet. Je nach Größe können die Calciumsilikat-Platten aus einzelnen Abschnitten zusammengesetzt sein.The inner wall and the outer wall are each preferably formed of calcium silicate plates. Depending on the size, the calcium silicate plates can be composed of individual sections.

Die Innenwandung und die Außenwandung sind unter Ausbildung eines Spaltraums beabstandet voneinander angeordnet. Im Spaltraum zwischen der Innenwandung einerseits und der Außenwandung andererseits befindet sich ein Traggerüst. Dieses ist aus einzelnen Stahlhohlprofilen gebildet und erbringt die Versteifung des endfertigen Kanals, so dass eine hinreichende Stabilität des Gesamtkanals gegeben ist.The inner wall and the outer wall are spaced apart to form a gap space. In the gap between the inner wall on the one hand and the outer wall on the other hand is a support frame. This is formed from individual hollow steel profiles and provides the stiffening of the final channel, so that a sufficient stability of the entire channel is given.

Die aus Calciumsilikat-Platten gebildeten Wandungen liegen an den Hohlprofilen des Traggerüsts an. Eine im Besonderen ausgestaltete Verbindung zwischen den Calciumsilikat-Platten einerseits und den Hohlprofilen des Traggerüsts andererseits ist nicht vorgesehen.The walls formed of calcium silicate plates abut against the hollow profiles of the support framework. A specially designed connection between the calcium silicate plates on the one hand and the hollow sections of the support frame on the other hand is not provided.

Im Spaltraum zwischen den beiden Wandungen sind neben dem Traggerüst auch Streifen aus Calciumsilikat angeordnet. Mittels dieser Calciumsilikat-Streifen sind die Innenwandung einerseits und die Außenwandung andererseits mechanisch miteinander verbunden. Es ist insofern ein mechanischer Verbund aus doppelwandig angeordneten Calciumsilikat-Platten geschaffen, wobei im Spaltraum zwischen den beiden Platten, das heißt zwischen der innenliegenden Platte einerseits und der außenliegenden Platte andererseits ein Traggerüst aus Stahlhohlprofilen ausgebildet ist, welches der Gesamtstabilität des Entrauchungskanals dient.In the gap between the two walls, strips of calcium silicate are arranged in addition to the support frame. By means of these calcium silicate strips, the inner wall on the one hand and the outer wall on the other hand are mechanically interconnected. It is insofar arranged a mechanical composite of double-walled Calcium silicate plates created, wherein in the gap between the two plates, that is, between the inner plate on the one hand and the outer plate on the other hand, a support frame made of hollow steel profiles is formed, which serves the overall stability of the smoke control.

Zur Ausbildung eines Entrauchungskanals nach der Erfindung wird in einem ersten Schritt zunächst eine Calciumsilikat-Platte mit Calciumsilikat-Streifen ausgerüstet. Auf die so vorbereitete Calciumsilikat-Platte ist sodann ein aus Stahlhohlprofilen gebildetes Traggerüst zu legen. In einem weiteren Schritt ist auf das Traggerüst eine zweite Calciumsilikat-Platte zu legen, die mit den zwischen der ersten und der zweiten Platte angeordneten Calciumsilikat-Streifen zu verbinden ist. Es entsteht so ein sandwichartiger Aufbau aus einer ersten und einer zweiten Calciumsilikat-Platte, die über dazwischen angeordnete Calciumsilikat-Streifen miteinander verbunden sind. Das ebenfalls zwischen den beiden Calciumsilikat-Platten ausgebildete Traggerüst sorgt für die gewünschte Stabilität.To form a smoke extraction duct according to the invention, a calcium silicate plate is firstly equipped with calcium silicate strips in a first step. On the thus prepared calcium silicate plate then a support frame formed from hollow steel profiles is to be laid. In a further step, a second calcium silicate plate is to be placed on the support frame, which plate is to be connected to the calcium silicate strips arranged between the first and the second plate. The result is a sandwich-like structure of a first and a second calcium silicate plate, which are interconnected via interposed calcium silicate strips. The support frame also formed between the two calcium silicate plates provides the desired stability.

Ein in vorbeschriebener Weise ausgebildeter Sandwich-Verbund dient als Seitenwand für einen in erfindungsgemäßer Weise ausgebildeten Entrauchungskanal. Bei einer im Querschnitt rechteckförmigen Ausgestaltung des Entrauchungskanals kommen vier solcher Seitenwände zum Einsatz, die entlang ihrer Stoßkanten miteinander verbunden sind.A sandwich composite formed in the manner described above serves as a side wall for a smoke extraction duct formed in accordance with the invention. In a cross-sectionally rectangular configuration of the smoke extraction duct four such side walls are used, which are interconnected along their abutting edges.

Die mechanische Verbindung, insbesondere die mechanische Verbindung zwischen Innenwandung und/oder Außenwandung mit den dazwischen angeordneten Calciumsilikat-Streifen erfolgt durch Verklammerung. Eine solche Verbindung hat sich als ausfallsicher erwiesen und gestattet eine einfach durchzuführende Montage, insbesondere bei Einsatz von Klammerschussgeräten.The mechanical connection, in particular the mechanical connection between the inner wall and / or outer wall with the calcium silicate strips arranged therebetween, takes place by clamping. Such a connection has proven to be fail-safe and allows easy to carry out assembly, especially when using Klammerschussgeräten.

Das Traggerüst ist aus einzelnen Profilsegmenten gebildet, wobei es bevorzugt ist, dass die Profilsegmente in Kanallängsrichtung hintereinander angeordnet sind. Um eine hinreichende Stabilität des endfertig ausgebildeten Entrauchungskanals zu gewährleisten, ist es gemäß eines weiteren Merkmals der Erfindung vorgesehen, dass zwei benachbarte Profilsegmente einen Maximalabstand von 600 mm aufweisen. Je nach Größe des lichten Kanaldurchmessers müssen zur Erzielung der geforderten Stabilität auch andere Maximalabstände eingehalten werden, beispielsweise von 500 mm, 400 mm oder 300 mm. Von erfindungswesentlicher Bedeutung ist indes, dass unter Berücksichtigung des lichten Kanaldurchmessers ein solcher Abstand zwischen den einzelnen Profilsegmenten des Traggerüsts gewählt wird, der die geforderte Gesamtstabilität des endfertig ausgebildeten Entrauchungskanals erbringt.The support frame is formed from individual profile segments, wherein it is preferred that the profile segments are arranged one behind the other in the channel longitudinal direction. In order to ensure a sufficient stability of the smoke evacuation duct designed to be finished, according to a further feature of the invention it is provided that two adjacent profile segments have a maximum distance of 600 mm. Depending on the size of the clear channel diameter other maximum distances must be maintained to achieve the required stability, for example, of 500 mm, 400 mm or 300 mm. Of essential importance to the invention, however, is that, taking into account the clear channel diameter such a distance between the individual profile segments of the framework is selected, which provides the required overall stability of the finished smoke evacuation channel.

Ein Profilsegment besteht aus einzelnen Hohlprofilen aus Stahl, die bevorzugterweise miteinander verschweißt sind. Dabei ist ein Profilsegment vorzugsweise ringartig ausgebildet, verfügt also über mehrere kanalumfangsseitig umlaufend angeordnete Hohlprofile. Bei einer rechteckförmigen Querschnittsausgestaltung besteht ein Profilsegment aus insgesamt vier Hohlprofilen, die zu einem rechteckförmigen Rahmen miteinander verschweißt sind. Ein solcher Rahmen stellt das Profilsegment dar, wobei mehrerer solcher Rahmen in Kanallängsrichtung hintereinander angeordnet das Traggerüst nach der Erfindung ergeben.A profile segment consists of individual hollow sections made of steel, which are preferably welded together. In this case, a profile segment is preferably formed ring-like, thus has a plurality of circumferentially circumferentially arranged peripheral hollow profiles. In a rectangular cross-sectional configuration, a profile segment consists of four hollow sections, which are welded together to form a rectangular frame. Such a frame represents the profile segment, wherein a plurality of such frames arranged in the channel longitudinal direction one behind the other, the support frame according to the invention.

Zur Verbindung von Innenwandung und Außenwandung unter Zwischenordnung des Traggerüsts ist es gemäß einem weiteren Merkmal der Erfindung vorgesehen, dass die Calciumsilikat-Streifen parallel zu den Profilsegmenten ausgebildet quer zur Kanallängserstreckung ausgerichtet sind. Dabei ist bevorzugterweise jedem Profilsegment, noch mehr bevorzugt jedem Hohlprofil eines jeden Profilsegments ein Calciumsilikat-Streifen direkt nebengeordnet. Eine Verschiebebewegung, das heißt eine Relativbewegung zwischen den Calciumsilikat-Platten einerseits und dem Traggerüst andererseits ist insbesondere bei einer solchen Konstruktion nicht möglich.To connect the inner wall and outer wall with the interposition of the support frame, it is provided according to a further feature of the invention that the calcium silicate strips are aligned parallel to the profile segments formed transversely to the channel longitudinal extent. In this case, preferably each profile segment, more preferably each hollow profile of each profile segment is directly adjacent to a calcium silicate strip. A displacement movement, that is, a relative movement between the calcium silicate plates on the one hand and the support frame on the other hand is not possible in particular in such a construction.

Der Spaltraum zwischen der Innenwandung einerseits und der Außenwandung andererseits ist im Übrigen mit Mineralwolle aufgefüllt. In Kombination mit dem Calciumsilikat-Platten wird so die erwünschte Feuerwiderstandsklasse L30, L60, L90 oder L180 erreicht. Dabei darf ein erfindungsgemäßer Kanal mit einem Betriebsdruck von +500 bar bis -1.500 bar betrieben werden und ist mit einer Höchsttemperatur von 300°C geprüft.The gap between the inner wall on the one hand and the outer wall on the other hand is otherwise filled with mineral wool. In combination with the calcium silicate boards, the desired fire resistance class L30, L60, L90 or L180 is achieved. In this case, a channel according to the invention may be operated with an operating pressure of +500 bar to -1,500 bar and is tested with a maximum temperature of 300 ° C.

Der Entrauchungskanal 1 verfügt über insgesamt vier Seitenwände 10, 11, 12 und 13, wie sich insbesondere aus der Darstellung nach Fig. 2 ergibt. Diese Seitenwände 10, 11, 12 und 13 sind zur Ausbildung des Entrauchungskanals 1 miteinander verbunden. Der Entrauchungskanal 1 verfügt über eine im Querschnitt insgesamt rechteckförmige Ausgestaltung, wie sich ebenfalls im Besonderen aus der Darstellung nach Fig. 2 ergibt.The smoke extraction duct 1 has a total of four side walls 10, 11, 12 and 13, as can be seen in particular from the illustration Fig. 2 results.

Diese Hohlprofile 5 sind Teil eines Traggerüsts 15, wobei das Traggerüst 15 aus einzelnen Profilsegmenten 14 gebildet ist, die in Kanallängsrichtung 6 hintereinander angeordnet sind. Dabei ist ein jedes Profilsegment 14 aus vier Hohlprofilen 5 gebildet, die miteinander verschweißt sind.

Dieser Sachzusammenhang ergibt sich insbesondere aus der Darstellung nach Fig. 1.As shown Fig. 3 can be further removed, 10 to 13 hollow sections 5 are arranged in the gap 4 of each side wall, which are formed in the embodiment shown as Hohlvierkantrohr steel. These hollow sections 5 are part of a support frame 15, wherein the support frame 15 is formed from individual profile segments 14, which are arranged in the channel longitudinal direction 6 in a row. In this case, each profile segment 14 is formed from four hollow profiles 5, which are welded together. In this case, each profile segment 14 is like a ring-like frame, that is, the hollow sections 5 of each profile segment 14 are circumferentially formed on the circumference of the channel. This factual context arises in particular from the presentation below Fig. 1 ,

Zur Verbindung von Innenwandung 2 und Außenwandung 3 dienen ebenfalls im Spaltraum 4 zwischen einer Innenwandung 2 und einer Außenwandung 3 angeordnete Calciumsilikat-Streifen 7. Mit diesen Calciumsilikat-Streifen 7 sind die Innenwandung 2 und die Außenwandung 3 mechanisch verbunden, vorzugsweise durch Verklammerung. Dabei ist jedem Hohlprofil 5 des Traggerüsts 15 ein Calciumsilikat-Streifen 7 direkt nebengeordnet, wie sich aus der Darstellung nach Fig. 3 ergibt.To connect the inner wall 2 and the outer wall 3 are also in the gap 4 between an inner wall 2 and an outer wall 3 arranged calcium silicate strips 7.

An inner wall 2 and an outer wall 3 are provided, which are mechanically connected to one another via calcium silicate strips 7 arranged therebetween, in particular by clamping. An arranged in the gap between the inner wall 2 and outer wall 3 support frame 15 serves to achieve a sufficient stability of the finished smoke evacuation channel. 1

Die die Innenwandung 2 beziehungsweise die die Außenwandung 3 bildenden Calciumsilikat-Platten können aus einzelnen Abschnitten 9 gebildet sein. Diese sind bevorzugterweise nicht direkt miteinander verbunden, sondern stützen sich jeweils über entsprechende Calciumsilikat-Streifen 7 ab, mit denen sie mechanisch gekoppelt sind.The inner wall 2 and the outer wall 3 forming calcium silicate plates may be formed of individual sections 9. These are preferably not directly connected to each other, but are each supported via corresponding calcium silicate strips 7, with which they are mechanically coupled.

Zur Erzielung einer Mindeststabilität ist vorgesehen, dass der Abstand A (vgl. Fig. 3) zwischen zwei benachbarten Hohlprofilen 5 zweier benachbarter Profilsegmente 14 maximal 600 mm beträgt. Je nach zu erwartender Belastung können auch andere Abstandswerte vorgesehen sein. Der Maximalabstand von 600 mm gilt für einen Entrauchungskanal 1 der Feuerwiderstandsklasse L90 mit einem lichten Durchströmungsquerschnitt von a = 3.200 mm x b = 2.500 mm. Ein solcher Kanal kann bei einem Betriebsdruck von +500 bar bis -1.500 bar und bis zu einer Temperatur von 300°C betrieben werden.To achieve a minimum stability is provided that the distance A (see. Fig. 3 ) between two adjacent hollow profiles 5 of two adjacent profile segments 14 is a maximum of 600 mm. Depending on the expected load, other distance values may also be provided. The maximum distance of 600 mm applies to a smoke extraction duct 1 of fire resistance class L90 with a clear flow cross-section of a = 3,200 mm xb = 2,500 mm. Such a duct can be operated at an operating pressure of +500 bar to -1,500 bar and up to a temperature of 300 ° C.

Mit dem erfindungsgemäßen Entrauchungskanal 1 wird insgesamt eine Kanalkonstruktion geschaffen, die es gestattet, bei Einhaltung der Stabilitätsvoraussetzungen und Erfüllung der Anforderungen an die Feuerwiderstandsklasse L90 einen im Vergleich zum Stand der Technik erheblich vergrößerten Kanalquerschnitt zu gestattet. So ist das aus dem Stand der Technik bekannte lichte Maß von 2.425 mm x 1.000 mm auf 3.200 mm x 2.500 mm gesteigert.With the smoke extraction duct 1 according to the invention a total of a channel construction is created, which allows, in compliance with the stability requirements and compliance with the requirements of the fire resistance class L90 a considerably larger compared to the prior art channel cross-section. Thus, the known from the prior art clear dimension of 2,425 mm x 1,000 mm is increased to 3,200 mm x 2,500 mm.
