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 mindestens teilweise durch abgewinkelte Randstreifen der Deckbleche gebildet. Das Türblatt enthält einen Rahmen, der aus einem Profil gebildet ist. In Türblattebene sind Längsrandstreifen des mit einer zu den Stirnseiten des Türblattes hin offenen Nut versehen Profils abgewinkelt.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 at least partially formed by angled edge strips of the cover plates. The door leaf contains a frame which is formed from a profile. In the door leaf level, longitudinal edge strips of the profile provided with a groove open towards the front sides of the door leaf are angled.
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 to be solved to achieve an easy to manufacture and lightweight door, which, moreover, is sufficiently reliable fire-retardant at the same time and without further measures in the area of the frame.
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, it is possible to seal the gap between the door leaf and the frame through the cover strip filled with heat-foaming material, the elongated holes in the profile are that forms the front frame of the door leaf, 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 die Feuerschutztür sich durch eine besonders hohe Stabilität auszeichnet, ohne dadurch ein großes Gewicht zu erhalten.The invention has for its object to propose a fire protection door of the type described above using mineral fiber panels to be arranged in the door leaf box, the fire protection door being characterized by a particularly high stability without being heavy.
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.With the design according to the invention, two mineral fiber boards can be combined in one with the help of the frame Arrange the distance parallel to each other, which 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 Glue or spot welding are to be connected.
Nach einer Ausgestaltung der Erfindung läßt sich die Biegesteifigkeit des Rahmens und damit die Stabilität des Türblattes insgesamt noch dadurch steigern, daß das den Rahmen bildende Profil mindestens in seinem die Nut begrenzenden Bereich mit sich in Profillängsrichtung erstreckenden Versteifungssicken versehen ist.According to an embodiment of the invention, the bending stiffness of the frame and thus the stability of the door leaf can be increased overall in that the profile forming the frame is at least in its the area delimiting the groove is provided with stiffening beads extending in the longitudinal direction of the profile.
Nach einer weiteren Ausgestaltung der Erfindung ist zur versenkten Anordnung des Stulpes eines Schloßkastens der Öffnungsquerschnitt der Nut auf beiden Laibungsseiten mit treppenförmigen Erweiterungen versehen.According to a further embodiment of the invention, for the recessed arrangement of the faceplate of a lock case, the opening cross section of the groove is provided with step-like extensions on both reveal sides.
Sind die Deckbleche des Türblattes nicht unmittelbar miteinander verbunden, läßt sich für die dann allein durch den Rahmen gebildete unvermeidbare Wärmeübertragungsbrücke ein möglichst langer Wärmeübertragungsweg schaffen, in dem die Nut im Rahmenprofil verhältnismäßig tief ausgebildet wird, was den weiteren Vorteil hat, nach einer Ausgestaltung der Erfindung in der Nut einen stabilen Gipsstollen anordnen zu können. Durch den Gipsstollen läßt sich der Rahmen zusätzlich aussteifen und erhält dadurch selbst dann ein großes Biegewiderstandsmoment, wenn das Material des Profils, aus dem der Rahmen gebildet ist, verhältnismäßig dünnwandig ist.If the cover plates of the door leaf are not directly connected to one another, a heat transfer path that is as long as possible can be created for the inevitable heat transfer bridge then formed solely by the frame, in which the groove in the frame profile is formed relatively deep, which has the further advantage, according to one embodiment of the invention to be able to arrange a stable gypsum gallery in the groove. The gypsum tunnel allows the frame to be additionally stiffened and thereby receives a large bending moment even when the material of the profile from which the frame is formed is relatively thin-walled.
Vorzugsweise sind der Querschnitt der Nut des Profils und der Querschnitt des Gipsstollens so aufeinander abgestimmt, daß der Gipsstollen die Nut des Rahmens gänzlich ausfüllt.The cross section of the groove of the profile and the cross section of the gypsum gallery are preferably matched to one another in such a way that the gypsum gallery completely fills the groove of the frame.
