The distance holders are strips of plaster cardboard plates and/or two layers of plaster cardboard plates and mineral fibre plates adhered together.

Description

Die Erfindung betrifft ein Türblatt einer Feuerschutztür, das einen aus Deckblechen gebildeten Türblattkasten aufweist, in dessen Inneren sich beidseitig einer sich im wesentlichen vollständig zwischen randseitigen Verstärkungen des Türblattes erstreckenden Luftschicht eine Dämmschicht aus Mineralfaserplatten befindet.The invention relates to a door leaf of a fire door, which is formed from cover plates Has door leaf box, in the interior of which one is essentially complete on both sides air layer extending between edge reinforcements of the door leaf Insulation layer made of mineral fiber boards.

Ein derartiges Türblatt ist beispielsweise aus der DE 40 07 733 A1 bekannt. Die Ansichtsseiten dieses Türblatts bestehen aus zwei Deckblechen und die Stirnseiten sind im wesentlichen von einem Rahmen gebildet. Der Rahmen besitzt einen rinnenartigen Querschnitt mit an beiden Oberseiten zweifach abgewinkelten Randstreifen, mit denen er jeweils in angepaßte Nuten in den Stirnseiten der Mineralfaserplatten eingreift. Der Rahmen ist im Inneren zu einem großen Teil mit einem Füllstollen ausgefüllt. Mit dem bekannten Türblatt lassen sich mit Hilfe des Rahmens zwei Mineralfaserplatten beidseitig einer Luftschicht in einem parallelen Abstand zueinander anordnen. Aufgrund des formschlüssigen Ineinandergreifens von Rahmen und Mineralfaserplatten wird in Verbindung mit dem Füllstollen innerhalb des Rahmens eine verbesserte Stabilität der Gesamtkonstruktion erzielt.Such a door leaf is known for example from DE 40 07 733 A1. The view pages this door leaf consist of two cover plates and the front faces are essentially formed by a frame. The frame has a groove-like cross section with both Top sides of double angled edge strips, with which he each fit in grooves engages in the end faces of the mineral fiber boards. The frame is one inside largely filled with a tunnel. With the well-known door leaf can be with the help the frame two mineral fiber plates on both sides of an air layer at a parallel distance arrange to each other. Due to the interlocking interlocking of frames and mineral fiber boards is used in conjunction with the filler tunnel within the frame improved stability of the overall construction.

Als Nachteil des bekannten Türblatts ist es anzusehen, daß die Isolierwirkung der Schichtabfolge Mineralfaserplatte - Luft - Mineralfaserplatte für bestimmte Anforderungen zu gering sein kann. Dies resultiert unter anderem daraus, daß ein Trend zu immer leichteren Mineralfaserplatten besteht, deren Isolierwirkung darunter jedoch häufig leidet.A disadvantage of the known door leaf is that the insulating effect of the layer sequence Mineral fiber board - air - mineral fiber board too low for certain requirements can be. This results among other things from the fact that there is a trend towards ever lighter mineral fiber boards exists, the insulating effect of which, however, often suffers.

Der Erfindung liegt die Aufgabe zugrunde, ein Türblatt einer Feuerschutztür bereitzustellen, bei der die Isolationswirkung erhöht wird, und die sich durch ihre einfache Herstellbarkeit auszeichnet.The invention has for its object to provide a door leaf of a fire door, in which the insulation effect is increased, and which are easy to manufacture distinguished.

Ausgehend von dem Türblatt der eingangs beschriebenen Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß beidseitig der Luftschicht jeweils zwei parallel zueinander verlaufende Dämmschichten aus Mineralfaserplatten und Gipskartonplatten angeordnet sind. Starting from the door leaf of the type described in the introduction, this object is achieved according to the invention solved in that on both sides of the air layer two parallel to each other Insulation layers made of mineral fiber boards and plasterboard are arranged.

Aufgrund der hervorragenden Isolationseigenschaften von Gipskartonplatten kann der Wärmedurchtrittswiderstand bei der erfindungsgemäßen Tür gegenüber einer Tür, die rein mit Mineralfaserplatten als Isolationsmaterial ausgestattet ist, deutlich gesteigert werden. Die besondere Isolations- bzw. Kühlwirkung der Gipskartonplatten liegt darin begründet, daß in der Kristallstruktur des Gipses eine große Menge Wasser eingelagert ist, das infolge Hitzebelastung als kühlender Wasserdampf abgegeben wird. Diese Wasserdampfabgabe macht sich selbst bei mehr als 90 Minuten dauernden Hitzebeaufschlagungen noch sehr positiv bemerkbar. Da das Türblatt gemäß der Erfindung in der Mitte eine Luftschicht aufweist und des weiteren neben den Gipskartonplatten auch noch Mineralfaserplatten besitzt, kann sein Gewicht - insbesondere im Vergleich mit einem vollständig mit Gips ausgefüllten Türblatt - sehr niedrig gehalten werden.Due to the excellent insulation properties of gypsum plasterboard, the thermal resistance can in the door according to the invention opposite a door that purely with Mineral fiber boards equipped as insulation material can be increased significantly. The special one Insulation or cooling effect of the plasterboard is due to the fact that in the The crystal structure of the gypsum contains a large amount of water due to heat is released as cooling water vapor. This release of water vapor does away still very positively noticeable even with heat exposure lasting more than 90 minutes. Since the door leaf according to the invention has an air layer in the middle and further In addition to the gypsum plasterboard, it also has mineral fiber boards, its weight can - especially low compared to a door leaf completely filled with plaster being held.

Die in der Mitte des Türblatts befindliche Luftschicht hat des weiteren den positiven Effekt, daß sich darin brennbare Gase, die beispielsweise aus der Zersetzung der bei der Herstellung der Mineralfaserplatten verwendeten organischen Bindemittel herrühren, ansammeln können, wodurch ein unkontrollierter Gasaustritt verhindert wird. Die mittlere Luftschicht wirkt somit nach Art eines ausgleichenden Gaspuffers.The air layer in the middle of the door leaf also has the positive effect that there are flammable gases, for example from the decomposition of the in the manufacture the mineral binders used organic binder originate, can accumulate, which prevents uncontrolled gas leakage. The middle layer of air works in the manner of a balancing gas buffer.

Eine besonders vorteilhafte Ausgestaltung des Türblatts besteht darin, daß beidseitig an die Luftschicht eine Gipskartonplatte anschließt. Auf diese Weise wird aufgrund des Wasserdampfaustritts aus der Gipskartonplatte in die Luftschicht eine spürbare Kühlung der sich unter Umständen darin ansammelnden brennbaren Gase erreicht. Ein Entzünden dieser Gase, das einen sehr unerwünschten Temperaturanstieg zur Folge hätte, kann daher vermieden werden. Auf diese Weise ergibt sich ein symmetrischer Aufbau des Türblatts, bei dem die Schichten Deckblech - Mineralfaserplatte - Gipskartonplatte - Luft - Gipskartonplatte - Mineralfaserplatte - Deckblech aufeinanderfolgen.A particularly advantageous embodiment of the door leaf is that on both sides of the Air layer connects a plasterboard. This way, due to the water vapor leakage from the plasterboard into the air layer a noticeable cooling of the under Under certain circumstances, the combustible gases accumulated therein. Igniting these gases, the a very undesirable rise in temperature could therefore be avoided. This results in a symmetrical structure of the door leaf, in which the layers Cover plate - mineral fiber board - gypsum board - air - gypsum board - mineral fiber board - Follow the cover plate in succession.

Die Erfindung weiter ausgestaltend, ist vorgesehen, daß die Gipskartonplatten mit den Mineralfaserplatten verklebt sind. Auf diese Weise wird eine Sandwichplatte erzielt, durch die sich die Herstellung des erfindungsgemäßen Türblatts weiter vereinfachen läßt. Besonders vorteilhaft ist es in diesem Zusammenhang, wenn das für die jeweiligen Türblattabmessungen benötigte Sandwichelement bereits aus großflächigem Sandwichmaterial der vorbeschriebenen Art ausgeschnitten werden kann.Developing the invention further, it is provided that the plasterboard with the mineral fiber boards are glued. In this way, a sandwich plate is obtained through which can further simplify the manufacture of the door panel according to the invention. Particularly advantageous it is in this context if that required for the respective door leaf dimensions Sandwich element already made of large-area sandwich material of the type described above can be cut out.

In Anbetracht der vergleichsweise dünnwandigen Deckbleche ist eine Stabilitätserhöhung des Türblatts - insbesondere bei Druckbelastung auf die Ansichtsflächen - zu erzielen, wenn die an ein ansichtsseitiges Deckblech angrenzende Dämmschicht mit diesem verklebt ist.In view of the comparatively thin-walled cover plates, the stability of the Door leaf - especially when pressure is exerted on the visible surfaces - when the an insulation layer adjacent to a face-side cover plate is glued to it.

Der oberste Bereich eines Türblatts ist zum einen aufgrund der physikalisch bedingten dort herrschenden höchsten Temperaturen und zum anderen aufgrund des dort von einer Ansichtsseite zur anderen Ansichtsseite durchgehenden stirnseitigen Deckblechs der bei einer Brandschutzprüfung kritischste Bereich. Um die dort auftretenden Temperaturen zu reduzieren, wird nach der Erfindung vorgeschlagen, das Türblatt unterhalb der oberen Stirnseite mit einem Verstärkungsprofil in Form eines Gipsstollens zu versehen. Hierdurch kann sowohl die Temperaturbelastung aufgrund der bereits zuvor beschriebenen hervorragenden Kühlwirkung des Gipses gesenkt als auch ein sehr schädlicher Verzug des Türblatts in diesem Bereich verhindert werden.The uppermost area of a door leaf is there, on the one hand, due to the physical condition prevailing highest temperatures and on the other hand due to the view from there to the other side of the front faceplate of the during a fire protection test most critical area. To reduce the temperatures occurring there, proposed according to the invention, the door leaf below the upper end face with a To provide reinforcement profile in the form of a plaster tunnel. As a result, both the temperature load due to the excellent cooling effect of the Lowered plaster as well as preventing a very harmful distortion of the door leaf in this area become.

Wenn der Gipsstollen im Querschnitt T-förmig ist und mit einem freien Schenkel in die Luftschicht hineinragt, deren Dicke mit der Dicke des Schenkels übereinstimmt, dient dieser Gipsstollen gleichzeitig als Abstandshalter bzw.

Figure 00030001
Support "for the sandwich panels made of plasterboard and mineral fiber panels adjoining these on both sides, which results in advantages in production.

Ferner wird vorgeschlagen, daß die Breite einer sich von der unteren Stirnseite in die Luftschicht erstreckenden Nut zur Aufnahme einer Dichtungsvorrichtung in ihrer Breite mit der Dicke der Luftschicht übereinstimmt. Auch hierdurch lassen sich die Herstellungsschritte vereinfachen, da die Sandwichplatten beidseitig des die Nut bildenden Blechs eingeschoben werden können. It is also proposed that the width of one of the lower end face in the air layer extending groove for receiving a sealing device in its width with the Thickness of the air layer matches. This also simplifies the manufacturing steps, since the sandwich panels are inserted on both sides of the sheet forming the groove can.

Wenn außerdem die Dicke des Schloßkastens mit der Dicke der Luftschicht übereinstimmt, sind für den Schloßkasten keine Ausschnitte in den Sandwichplatten erforderlich. Diese erstrecken sich vielmehr durchgängig von beispielsweise dem oberen Gipsstollen bis zur unteren Stirnseite der Tür.In addition, if the thickness of the lock case matches the thickness of the air layer, no cutouts in the sandwich panels are required for the lock case. This Rather, they extend continuously from, for example, the upper gypsum gallery to the lower one Front of the door.

Vorteilhafterweise beträgt die Dicke der Gipskartonplatten zwischen 70 % und 80 % der Dicke der Mineralfaserplatten. Mit vergleichsweise geringer Dicke der Gipskartonplatten wird bereits die erwünschte deutliche Verbesserung der Isoliereigenschaften erzielt. Der vergleichsweise geringe Gipsanteil erlaubt ein niedriges Gewicht des Türblatts.Advantageously, the thickness of the plasterboard is between 70% and 80% of the thickness of mineral fiber boards. With a comparatively small thickness of plasterboard already achieved the desired significant improvement in the insulating properties. The comparative low percentage of gypsum allows a low weight of the door leaf.

Eine Weiterbildung der Erfindung besteht darin, daß zwischen gegenüberliegenden und durch die Luftschicht getrennten Dämmschichten an diesen anliegende Abstandshalter angeordnet sind, wodurch über die gesamte Fläche des Türblatts eine definierte Positionierung der Dämmschichten zueinander gewährleistet wird.A further development of the invention is that between opposite and through the air layer separated insulation layers arranged on these spacers are, whereby a defined positioning of the Insulation layers to each other is guaranteed.

Wenn die Abstandshalter Streifen von Gipskartonplatten und/oder von zwei miteinander verklebten Schichten aus Gipskartonplatten und Mineralfaserplatten sind, lassen sich diese sinnvollerweise aus Abfallstücken beim Zuschnitt der den jeweiligen Türblattabmaßen angepaßten Sandwichelemente herstellen.If the spacers strips of plasterboard and / or two stuck together Layers of gypsum plasterboard and mineral fiber boards, these can be usefully from pieces of waste when cutting the appropriate to the respective door leaf dimensions Make sandwich elements.

Schließlich wird zur weiteren Stabilitätserhöhung des Türblatts noch vorgeschlagen, auf beiden vertikalen Stirnseiten des Türblattkastens in dessen Inneren zwei an die Stirnseiten angrenzende und parallel zu diesen verlaufende Verstärkungsprofile aus gefalztem Stahlblech anzuordnen.Finally, it is proposed to further increase the stability of the door leaf, on both vertical end faces of the door leaf box inside two adjoining the end faces and reinforcing profiles made of folded sheet steel running parallel to these to arrange.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels eines Türblatts, das in der Zeichnung dargestellt ist, näher erläutert. Es zeigt:

Eine in den Figuren 1 und 2 dargestellte Feuerschutztür 1 besteht aus einem Türblatt 2, das in der üblichen Weise über Bänder 3 und Angeln 4 drehbar in einer aus Stahlblech hergestellten Eckzarge 5 gelagert ist. Mit dem Türblatt ist eine Öffnung 6 verschließbar, die unten durch einen Fußbodenbelag 7, oben durch einen Türsturz 8 und jeweils seitlich durch Wandabschnitte 9 begrenzt wird. Die Eckzarge 5 ist in bekannter Weise fest mit den Wandabschnitten 9 und dem Türsturz 8 verbunden.A fire protection door 1 shown in Figures 1 and 2 consists of a door leaf 2, which in the usual way over bands 3 and 4 hinges in a made of sheet steel Corner frame 5 is stored. With the door leaf, an opening 6 can be closed, through the bottom a floor covering 7, above through a lintel 8 and laterally through wall sections 9 is limited. The corner frame 5 is fixed in a known manner with the wall sections 9 and the lintel 8 connected.

Das Türblatt 2 wird zu beiden Ansichtsseiten, beiden seitlichen Stirnseiten sowie zum Teil auch zu der oberen und unteren Ansichtsseite von zwei Deckblechen 10 und 11 begrenzt. Randstreifen 12, 13 und 14 des Deckblechs 11 sind - zum Teil zweifach - abgewinkelt und stoßen mit der zweiten Abwinklung gegen Randstreifen 15 und 16 des Deckblechs 10, wobei die Randstreifen 15 und 16 um die Randstreifen 12 und 14 in deren Endbereiche herumgeschlagen sind und somit für einen Zusammenhalt des Türblattkastens sorgen.The door leaf 2 is on both sides, both side faces and in part also limited to the top and bottom view side by two cover plates 10 and 11. Edge strips 12, 13 and 14 of the cover plate 11 are - in part twice - angled and encounter with the second bend against edge strips 15 and 16 of the cover plate 10, wherein the edge strips 15 and 16 around the edge strips 12 and 14 in their end regions are knocked around and thus ensure that the door leaf box is held together.

Im Inneren des Türblatts 2 befindet sich beidseitig einer mittleren Luftschicht 17 jeweils ein Sandwichelement 18, das durch Verklebung einer Mineralfaserplatte 19 mit einer Gipskartonplatte 20 gebildet ist. Beide Sandwichelemente 18 sind mit den Innenseiten der jeweils angrenzenden Deckbleche 10 und 11 verklebt. Die Dicke der Gipskartonplatte 20 beträgt ca. 76 % der Dicke der Mineralfaserplatte 19. Die Dicke der Luftschicht 17 entspricht der Dicke des aus Mineralfaserplatte 19 und Gipskartonplatte 20 gebildeten Sandwichelements 18.In the interior of the door leaf 2 there is a middle air layer 17 on both sides Sandwich element 18, which by gluing a mineral fiber board 19 with a plasterboard 20 is formed. Both sandwich elements 18 are adjacent to the inside of each Cover plates 10 and 11 glued. The thickness of the plasterboard 20 is approximately 76% of the thickness of the mineral fiber plate 19. The thickness of the air layer 17 corresponds to the thickness of the sandwich element 18 formed from mineral fiber plate 19 and plasterboard plate 20.

Im oberen Bereich des Türblatts 2 verläuft im wesentlichen über die gesamte Breite des Türblatts 2 ein Gipsstollen 21, der sich vollständig zwischen den beiden Deckblechen 10 und 11 erstreckt und mit diesen verklebt ist. Der Gipsstollen 21 bewirkt zum einen eine Stabilitätserhöhung in diesem durch Verzug gefährdeten Türblattbereich und zum anderen werden die Temperaturen in diesem kritischen Bereich durch den aus dem Gips austretenden Wasserdampf spürbar gesenkt. In the upper area of the door leaf 2 extends essentially over the entire width of the door leaf 2 a gypsum gallery 21 which is completely between the two cover plates 10 and 11 extends and is glued to them. The gypsum gallery 21 on the one hand increases the stability in this door leaf area, which is at risk of warping, and on the other hand, the Temperatures in this critical area due to the water vapor escaping from the plaster noticeably lowered.

Der Gipsstollen 21 besitzt im Querschnitt die Form eines T und ist aus sechs Schichten von Gipskartonplatten aufgebaut. Die beiden mittleren Schichten besitzen eine größere Breite als die an die Sandwichelemente 18 anstoßenden beiden äußeren Schichten und ragen daher nach Art einer Feder 22 in die Luftschicht 17. Auf diese Weise wirkt die Feder 22 als Abstandshalter für den oberen Endbereich der Sandwichelemente 18. Im übrigen wird durch die Verzahnung des Gipsstollens 21 mit den gegenüberliegenden Sandwichelementen 18 eine weitere Stabilitätserhöhung erreicht.The gypsum gallery 21 has the shape of a T in cross section and is composed of six layers of Plasterboard assembled. The two middle layers are wider than the two outer layers abutting the sandwich elements 18 and therefore protrude Kind of a spring 22 in the air layer 17. In this way, the spring 22 acts as a spacer for the upper end region of the sandwich elements 18. Otherwise, the toothing of the gypsum gallery 21 with the opposite sandwich elements 18 another Increased stability achieved.

Das Türblatt 2 ist an seiner unteren Stirnseite 23 mit einer rechteckförmigen Nut zur Aufnahme einer bekannten Rauchschutzdichtung versehen, die aus Übersichtlichkeitsgründen nicht dargestellt ist. Die Nut 24 wird von einem entsprechend abgewinkelten und mit den Deckblechen 10 und 11 verschweißten Blechprofil 25 gebildet. Zwischen dem Blechprofil 25 und den Innenseiten der Deckbleche 10 und 11 sind Taschen gebildet, die der Dicke der Sandwichelemente 18 entsprechen, so daß diese ohne Unterbrechung von dem Gipsstollen 21 bis zur unteren Stirnseite 23 des Türblatts 2 durchlaufen können. Oberhalb des Blechprofils 25 befindet sich ein aus zwei Schichten von Gipskartonplatten in entsprechender Dicke zusammengesetzter Abstandshalter 26.The door leaf 2 is on its lower end face 23 with a rectangular groove for receiving a known smoke protection seal, which is not for reasons of clarity is shown. The groove 24 is angled accordingly and with the cover plates 10 and 11 welded sheet metal profile 25 is formed. Between the sheet profile 25 and Inside the cover plates 10 and 11 pockets are formed, the thickness of the sandwich elements 18 correspond so that these without interruption from the plaster gallery 21 to the lower End face 23 of the door panel 2 can pass through. Is located above the sheet profile 25 is composed of two layers of plasterboard in the appropriate thickness Spacers 26.

Ein ähnlicher Abstandshalter 27 befindet sich auch an der Bandseite des Türblatts 2. Auf der Schloßseite des Türblatts 2 ist ebenfalls ein derartiger Abstandshalter vorhanden. Dieser ist jedoch aufgrund der Unterbrechung durch den Schloßkasten 28 zweigeteilt und aufgrund der Schnittebene in Figur 2 nicht sichtbar. Der Schloßkasten 28 weist dieselbe Breite wie die Luftschicht 17 bzw. die Abstandshalter 26 und 27 auf, so daß die Sandwichelemente 18 unmittelbar an die Außenseiten des Schloßkastens 28 angrenzen und in diesem Bereich nicht ausgeschnitten werden müssen. Aufgrund der fugenlosen Verlegung der Sandwichelemente 18 wird eine besonders große Dichtigkeit erzielt, die einen Gasaustritt durch die Sandwichelemente 18 verhindert. A similar spacer 27 is also on the hinge side of the door leaf 2. On the Such a spacer is also provided on the lock side of the door leaf 2. This is however, divided into two due to the interruption by the lock case 28 and due to the Section plane not visible in Figure 2. The lock case 28 has the same width as that Air layer 17 or the spacers 26 and 27, so that the sandwich elements 18 immediately adjoin the outside of the lock case 28 and not in this area need to be cut out. Due to the seamless laying of the sandwich elements 18 a particularly high level of tightness is achieved, which causes gas to escape through the sandwich elements 18 prevented.

Je nach Größe des Türblatts 2 befinden sich über dessen Höhe verteilt noch ein oder mehrere schmale Abstandshalter 29, die ebenfalls aus Streifen von Gipskartonplatten zusammengesetzt sind. Alternativ ist auch die Verwendung von Streifen von Mineralfaserplatten möglich oder einer Kombination der beiden letztgenannten Materialien.Depending on the size of the door leaf 2 there are still one or more distributed over its height narrow spacers 29, which are also composed of strips of plasterboard are. Alternatively, the use of strips of mineral fiber boards is possible or a combination of the latter two materials.

Zur weiteren Erhöhung der Stabilität des Türblatts 2 ist dieses an beiden gegenüberliegenden Längsseiten innen an den Randstreifen 14 des Deckblechs 11 mit jeweils einem sich in Längsrichtung des Türblatts 2 erstreckenden Verstärkungsprofil 30 aus mehrfach gefalztem Stahlblech verschweißt.To further increase the stability of the door leaf 2, this is on both opposite Long sides inside on the edge strips 14 of the cover plate 11, each with a lengthwise direction of the door leaf 2 extending reinforcing profile 30 made of multi-folded steel sheet welded.
