Definitions
- the invention relates to a fire protection door made of a box-shaped door leaf including mineral fiber panels.
- the view sides of the door leaf are formed by two cover plates.
- the end faces of the door leaf are formed by angled edge strips of the cover plates and a frame.
- the frame bridges a gap between the edge edges of the cover plates and is formed from a profile.
- the longitudinal edge strips of the profile which has an open groove, are angled.
- a bar foaming under the influence of heat is arranged.
- Such a fire door is known from DE-PS 34 23 550.
- the space between the cover sheets forming the visible sides of the door leaf and the surrounding frame forming the end faces of the door leaf is filled with mineral fibers. Because these are said to contain organic binders, there are fears that the organic binders will decompose at high temperatures and, as a result, flammable, explosive flue gas will develop and accumulate.
- the known fire protection door to form the end faces of the door leaf by means of a frame provided with openings, the frame being to consist of a profile which has a dovetail-shaped groove which is open to the outside.
- the openings in the frame should be arranged in the form of elongated holes in the base of the groove.
- a cover strip with two legs should reach behind the dovetail-shaped groove, the cover strip being to be filled with a non-flammable material that foams up in the heat.
- the weight saving of the door described above is negligibly small compared to conventional doors, since this results at best from the material punched out of the profile to form the elongated holes.
- the elongated holes themselves can prevent smoke gas accumulation within the door leaf. However, if flammable flue gas escapes from the door leaf, this increases the risk of spreading the fire to neighboring rooms. If, on the other hand, the cover strip filled with material that foams up when it is hot, the gap between the door leaf and the frame succeeds to seal, the elongated holes in the profile that forms the front frame of the door leaf are ineffective as a result, since the flue gas cannot escape.
- the invention has for its object to propose a fire door of the type described above using mineral fiber panels to be arranged in the door leaf box, the ignition of a fire being made difficult from one door leaf side to the other, which is extremely favored in the known fire door that the frame profile above wide edge areas of the cover plates are connected to these.
- two mineral fiber boards can be arranged parallel to one another with the aid of the frame, which distance corresponds to the width of the profile part from which the groove open to the outside is formed.
- the angled longitudinal edge strips of the profile engage positively in the front groove of the mineral fiber plates and fix them in the intended position without the frame covering the mineral fiber plates over the full width of the end face and a longitudinal edge strip having to lay on the outer side surfaces of the mineral fiber plates, whereby the heat-transferring contact area between the frame and the cover plates of the door leaf would be increased and, in addition, the mineral fiber plates would have to be arranged at a distance from the cover plates according to the thickness of the angled longitudinal edge strips.
- the frame and the mineral fiber boards can be prefabricated into a compact, stable unit that fills the interior of the door leaf box in a form-fitting manner, whereupon the cover plates have to be fitted snugly on both sides of the unit and their angled edge strips with the frame, for example, by Gluing or spot welding are to be connected.
- the frame can be advantageous to form the groove in the frame profile relatively deep, which has the further advantage that the filler tunnels arranged in the groove in addition to the foaming bar under heat can receive a relatively large cross-section.
- the frame can be stiffened particularly effectively and thereby receives a large bending moment even if the material of the profile from which the frame is formed is relatively thin-walled.
- the cross-section of the groove of the profile and the sum of the cross-sections of the bar and the filler block made of plaster are matched to one another such that the bar and the filler block completely fill the groove of the frame.
- the bar With regard to the arrangement of the bar and the filling tunnel to one another, it can be advantageous for the bar to cover the filling tunnel or else the filling tunnel to the outside.
- the foaming strip under the heat will partially push the filler tunnel out of the groove against the frame, so that in any case an effective seal in the gap area between the front face of the door leaf and the opposite surfaces of the frame is achieved.
- the bar and the filler tunnel are each covered with a PVC film. It can also be advantageous to cover the bar and the filler tunnel with a common PVC film.
- a separate arrangement of the bar and the filling gallery is advantageously possible according to a further embodiment of the invention in that two channels are formed from the PVC film, wherein the bar is arranged in one channel and the filling gallery is arranged in the other channel.
- a further embodiment of the invention provides that projections or depressions are provided in soffits in the groove of the frame, which correspond to depressions or projections of the PVC film.
- This configuration allows the bar and the filler studs to be held in a simple manner within the groove of the frame, for which it is sufficient that the PVC-coated ledge and the filler stud with a slight elastic deformation of the PVC casing and / or the soffits of the groove of the Frame are pressed into the groove, whereupon the projections snap into corresponding recesses and thus fixation is accomplished.
- the profile can be composed of two profile parts with a Z-shaped cross section, between the parts of which form the bottom of the groove, an insulating strip is arranged overlapping legs.

Abstract
Description
Die Erfindung betrifft eine Feuerschutztür aus einem kastenförmigen, Mineralfaserplatten einschließenden Türblatt. Die Ansichtsseiten des Türblatts sind durch zwei Deckbleche gebildet. Die Stirnseiten des Türblatts sind durch abgewinkelte Randstreifen der Deckbleche sowie einen Rahmen gebildet. Der Rahmen überbrückt einen Spalt zwischen den Randkanten der Deckbleche und ist aus einem Profil gebildet. In Türblattebene sind Längsrandstreifen des mit einer nach außen offenen Nut versehen Profils abgewinkelt. In der Nut ist eine unter Hitzeeinwirkung aufschäumende Leiste angeordnet.The invention relates to a fire protection door made of a box-shaped door leaf including mineral fiber panels. The view sides of the door leaf are formed by two cover plates. The end faces of the door leaf are formed by angled edge strips of the cover plates and a frame. The frame bridges a gap between the edge edges of the cover plates and is formed from a profile. In the door leaf level, the longitudinal edge strips of the profile, which has an open groove, are angled. In the groove, a bar foaming under the influence of heat is arranged.
Eine derartige Feuerschutztür ist aus der DE-PS 34 23 550 bekannt. Dabei ist der Raum zwischen den die Ansichtsseiten des Türblatts bildenden Deckblechen und dem umlaufenden, die Stirnseiten des Türblatts bildenden Rahmen mit Mineralfasern ausgefüllt. Weil diese organische Bindemittel enthalten sollen, wird befürchtet, daß bei hoher Temperatur ein Zerfall der organischen Bindemittel eintritt und sich infolgedessen brennbares, explosives Rauchgas entwickelt und ansammelt.Such a fire door is known from DE-PS 34 23 550. The space between the cover sheets forming the visible sides of the door leaf and the surrounding frame forming the end faces of the door leaf is filled with mineral fibers. Because these are said to contain organic binders, there are fears that the organic binders will decompose at high temperatures and, as a result, flammable, explosive flue gas will develop and accumulate.
Auch schwere Türen dieser Bauart sollen den Nachteil aufweisen, den Bereich des Spalts zwischen Türblatt und Zarge nicht hinreichend zuverlässig abzudichten und den Austritt eines explosiven Rauchgases in diesem Bereich nicht zu verhindern. Mit der bekannten Tür soll daher die Aufgabe gelöst werden, zu einer einfach herstellbaren und leichten Tür zu gelangen, die im übrigen zugleich und ohne weitere Maßnahmen im Bereich der Zarge hinreichend zuverlässig feuerhemmend ausgebildet ist.Even heavy doors of this type are said to have the disadvantage of not sealing the area between the door leaf and frame with sufficient reliability and of not preventing the escape of explosive flue gas in this area. With the known door, the task is therefore to be solved to one easy to manufacture and lightweight door to get, which is designed at the same time and without further measures in the frame sufficiently reliable fire retardant.
Zur Lösung dieser Aufgabe wird für die bekannte Feuerschutztür vorgeschlagen, die Stirnflächen des Türblatts durch einen mit Durchbrüchen versehenen Rahmen zu bilden, wobei der Rahmen aus einem Profil bestehen soll, das eine nach außen offene, schwalbenschwanzförmige Nut aufweist. Die Durchbrechungen im Rahmen sollen in Form von Langlöchern im Nutengrund angeordnet sein. Weiterhin soll eine Abdeckleiste mit zwei Schenkeln die schwalbenschwanzförmige Nut hintergreifen, wobei die Abdeckleiste mit einem bei Hitze aufschäumenden, nicht brennbaren Material gefüllt sein soll.To solve this problem, it is proposed for the known fire protection door to form the end faces of the door leaf by means of a frame provided with openings, the frame being to consist of a profile which has a dovetail-shaped groove which is open to the outside. The openings in the frame should be arranged in the form of elongated holes in the base of the groove. Furthermore, a cover strip with two legs should reach behind the dovetail-shaped groove, the cover strip being to be filled with a non-flammable material that foams up in the heat.
Die Gewichtsersparnis der vorstehend beschriebenen Tür ist gegenüber konventionellen Türen vernachlässigbar klein, da diese sich allenfalls aus dem zur Bildung der Langlöcher aus dem Profil ausgestanzten Material ergibt. Die Langlöcher selbst können zwar an sich eine Rauchgasansammlung innerhalb des Türblatts vermeiden. Tritt aber brennbares Rauchgas aus dem Türblatt aus, wird dadurch die Gefahr, den Brand auf Nachbarräume zu übertragen, begünstigt. Gelingt es dagegen, durch die mit bei Hitze aufschäumendem Material gefüllte Abdeckleiste den Spalt zwischen dem Türblatt und der Zarge abzudichten, sind die Langlöcher in dem Profil, das den stirnseitigen Rahmen des Türblatts bildet, im Ergebnis wirkungslos, da das Rauchgas nicht entweichen kann. In der Praxis ist man daher genötigt, als Füllstoff für den Türblattkasten Mineralfaserplatten einzusetzen, welche keine nennenswerten organischen Beimengungen enthalten, die im Brandfall brennbare, explosive Rauchgase freisetzen. Solche Mineralfaserplatten verfügen jedoch nur über eine geringe Stabilität und lassen sich nicht ohne weiteres innerhalb des Türblattkastens fixieren, was aber insbesondere dann erforderlich ist, wenn der Kasteninnenraum nicht völlig mit Mineralfasermaterial ausgefüllt ist.The weight saving of the door described above is negligibly small compared to conventional doors, since this results at best from the material punched out of the profile to form the elongated holes. The elongated holes themselves can prevent smoke gas accumulation within the door leaf. However, if flammable flue gas escapes from the door leaf, this increases the risk of spreading the fire to neighboring rooms. If, on the other hand, the cover strip filled with material that foams up when it is hot, the gap between the door leaf and the frame succeeds to seal, the elongated holes in the profile that forms the front frame of the door leaf are ineffective as a result, since the flue gas cannot escape. In practice, it is therefore necessary to use mineral fiberboard as a filler for the door leaf box, which does not contain any noteworthy organic admixtures that release flammable, explosive smoke gases in the event of a fire. However, such mineral fiber boards have only a low stability and cannot be fixed easily inside the door leaf box, which is particularly necessary if the box interior is not completely filled with mineral fiber material.
Der Erfindung liegt die Aufgabe zugrunde, eine Feuerschutztür der eingangs beschriebenen Art unter Verwendung von im Türblattkasten anzuordnenden Mineralfaserplatten vorzuschlagen, wobei das Durchzünden eines Brandes von einer Türblattseite zur anderen erschwert wird, was bei der bekannten Feuerschutztür dadurch außerordentlich begünstigt ist, daß dabei das Rahmenprofil über breite Randbereiche der Deckbleche mit diesen verbunden ist.The invention has for its object to propose a fire door of the type described above using mineral fiber panels to be arranged in the door leaf box, the ignition of a fire being made difficult from one door leaf side to the other, which is extremely favored in the known fire door that the frame profile above wide edge areas of the cover plates are connected to these.
Zur Lösung dieser Aufgabe wird von einer Feuerschutztür der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welche erfindungsgemäß die im kennzeichnenden Teil desselben angegebenen Merkmale aufweist.To achieve this object, a fire protection door of the generic type mentioned in the preamble of
Durch die erfindungsgemäße Ausbildung lassen sich mit Hilfe des Rahmens zwei Mineralfaserplatten in einem Abstand parallel voneinander anordnen, welcher der Breite des Profilteils entspricht, aus dem die nach außen offene Nut gebildet ist. Die abgewinkelten Längsrandstreifen des Profils greifen formschlüssig in die stirnseitige Nut der Mineralfaserplatten ein und fixieren diese in der vorgesehenen Position, ohne daß der Rahmen dazu die Mineralfaserplatten über die volle Breite der Stirnseite abdeckt und sich ein Längsrandstreifen auf die außen gelegenen Seitenflächen der Mineralfaserplatten auflegen muß, wodurch die hitzeübertragende Kontaktfläche zwischen dem Rahmen und den Deckblechen des Türblatts vergrößert würde und zudem die Mineralfaserplatten entsprechend der Stärke der abgewinkelten Längsrandstreifen in einem Abstand von den Deckblechen angeordnet werden müßten. Statt dessen lassen sich aufgrund der erfindungsgemäßen Anordnung der Rahmen und die Mineralfaserplatten zu einer kompakten, stabilen und den Innenraum des Türblattkastens formschlüssig ausfüllenden Baueinheit vorfertigen, worauf lediglich noch zu beiden Seiten der Baueinheit die Deckbleche satt anliegend aufzusetzen und deren abgewinkelte Randstreifen mit dem Rahmen beispielsweise durch Kleben oder Punktschweißen zu verbinden sind.By means of the design according to the invention, two mineral fiber boards can be arranged parallel to one another with the aid of the frame, which distance corresponds to the width of the profile part from which the groove open to the outside is formed. The angled longitudinal edge strips of the profile engage positively in the front groove of the mineral fiber plates and fix them in the intended position without the frame covering the mineral fiber plates over the full width of the end face and a longitudinal edge strip having to lay on the outer side surfaces of the mineral fiber plates, whereby the heat-transferring contact area between the frame and the cover plates of the door leaf would be increased and, in addition, the mineral fiber plates would have to be arranged at a distance from the cover plates according to the thickness of the angled longitudinal edge strips. Instead, due to the arrangement according to the invention, the frame and the mineral fiber boards can be prefabricated into a compact, stable unit that fills the interior of the door leaf box in a form-fitting manner, whereupon the cover plates have to be fitted snugly on both sides of the unit and their angled edge strips with the frame, for example, by Gluing or spot welding are to be connected.
Um für die durch den Rahmen gebildete unvermeidbare Wärmeübertragungsbrücke einen möglichst langen Wärmeübertragungsweg zu schaffen, kann es vorteilhaft sein, die Nut im Rahmenprofil verhältnismäßig tief auszubilden, was den weiteren Vorteil hat, daß der zusätzlich zu der unter Hitzeeinwirkung aufschäumenden Leiste in der Nut angeordnete Füllstollen aus nicht brennbarem Material einen verhältnismäßig großen Querschnitt erhalten kann. Durch einen solchen Füllstollen läßt sich der Rahmen besonders wirksam aussteifen und erhält dadurch selbst dann ein großes Biegewiderstandsmoment, wenn das Material des Profils, aus dem der Rahmen gebildet ist, verhältnismäßig dünnwandig ist.To make the longest possible for the inevitable heat transfer bridge formed by the frame To create heat transfer path, it can be advantageous to form the groove in the frame profile relatively deep, which has the further advantage that the filler tunnels arranged in the groove in addition to the foaming bar under heat can receive a relatively large cross-section. With such a filler tunnel, the frame can be stiffened particularly effectively and thereby receives a large bending moment even if the material of the profile from which the frame is formed is relatively thin-walled.
Vorzugsweise sind der Querschnitt der Nut des Profils und die Summe der Querschnitte der Leiste und des aus Gips hergestellten Füllstollens so aufeinander abgestimmt, daß die Leiste und der Füllstollen die Nut des Rahmens gänzlich ausfüllen.Preferably, the cross-section of the groove of the profile and the sum of the cross-sections of the bar and the filler block made of plaster are matched to one another such that the bar and the filler block completely fill the groove of the frame.
Bezüglich der Anordnung der Leiste und des Füllstollens zueinander kann es vorteilhaft sein, daß die Leiste den Füllstollen oder aber auch der Füllstollen die Leiste nach außen abdeckt. Bei der letztgenannten Anordnung wird die unter Hitzeeinwirkung aufschäumende Leiste den Füllstollen teilweise aus der Nut heraus gegen die Zarge drängen, so daß in jedem Falle eine wirksame Abdichtung im Spaltbereich zwischen der Stirnseite des Türblatts und den diesen gegenüberliegenden Flächen der Zarge zustande kommt.With regard to the arrangement of the bar and the filling tunnel to one another, it can be advantageous for the bar to cover the filling tunnel or else the filling tunnel to the outside. In the latter arrangement, the foaming strip under the heat will partially push the filler tunnel out of the groove against the frame, so that in any case an effective seal in the gap area between the front face of the door leaf and the opposite surfaces of the frame is achieved.
Nach einer weiteren Ausgestaltung der Erfindung sind die Leiste und der Füllstollen mit je einer PVC-Folie ummantelt. Es kann ebenso vorteilhaft sein, durch eine gemeinsame PVC-Folie die Leiste und den Füllstollen zu ummanteln.According to a further embodiment of the invention, the bar and the filler tunnel are each covered with a PVC film. It can also be advantageous to cover the bar and the filler tunnel with a common PVC film.
Eine getrennte Anordnung der Leiste und des Füllstollens ist nach einer weiteren Ausgestaltung der Erfindung in vorteilhafter Weise dadurch möglich, daß aus der PVC-Folie zwei Kanäle gebildet sind, worin in einem Kanal die Leiste und in dem anderen Kanal der Füllstollen angeordnet ist.A separate arrangement of the bar and the filling gallery is advantageously possible according to a further embodiment of the invention in that two channels are formed from the PVC film, wherein the bar is arranged in one channel and the filling gallery is arranged in the other channel.
Eine weitere Ausgestaltung der Erfindung sieht vor, daß in Laibungen der Nut des Rahmens Vorsprünge oder Vertiefungen vorgesehen sind, welche mit Vertiefungen bzw. Vorsprüngen der PVC-Folie korrespondieren.A further embodiment of the invention provides that projections or depressions are provided in soffits in the groove of the frame, which correspond to depressions or projections of the PVC film.
Durch diese Ausgestaltung lassen sich die Leiste und der Füllstollen in einfacher Weise innerhalb der Nut des Rahmens halten, wozu es ausreicht, daß die PVC-ummantelte Leiste und der Füllstollen unter einer geringfügigen elastischen Verformung der PVC-Ummantelung und/oder der Laibungen der Nut des Rahmens in die Nut eingepreßt werden, worauf die Vorsprünge in entsprechende Vertiefungen einrasten und somit eine Fixierung bewerkstelligt wird.This configuration allows the bar and the filler studs to be held in a simple manner within the groove of the frame, for which it is sufficient that the PVC-coated ledge and the filler stud with a slight elastic deformation of the PVC casing and / or the soffits of the groove of the Frame are pressed into the groove, whereupon the projections snap into corresponding recesses and thus fixation is accomplished.
Um hochwirksam die Übertragung der Hitze von einer Türblattseite zur anderen zu verhindern, können entweder zwischen den Teile der Stirnseiten des Türblatts bildenden Randstreifen der Deckbleche und den diesen gegenüberliegenden Streifen des den Rahmen bildenden Profils Isolierstreifen angeordnet sein und/oder kann das Profil aus zwei im Querschnitt Z-förmigen Profilteilen zusammengesetzt sein, zwischen dessen den Boden der Nut bildenden, sich überlappenden Schenkeln ein Isolierstreifen angeordnet ist.To highly effectively prevent the transfer of heat from one side of the door leaf to the other either between the parts of the end faces of the door leaf forming the edge strips of the cover plates and the strips of the insulating strip forming the frame opposite them, and / or the profile can be composed of two profile parts with a Z-shaped cross section, between the parts of which form the bottom of the groove, an insulating strip is arranged overlapping legs.
