Description

Die Erfindung bezieht sich auf eine Feuerschutztüre mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a fire protection door with the features of the preamble of claim 1 .

Feuerschutztüren werden in der Regel aus Stahlblech mit Isoliereinlagen und aus Stabilitätsgründen vorgesehenem Stahlrahmen gefertigt. Solche Stahltüren sind zwar hoch . hitzebeständig und standfest gegen ein Durchbrennen, doch führt die hohe Wärmeleitfähigkeit von Stahl dazu, daß die der befeuerten Seite abgewandte Türseite sich schnell hoch erhitzt. Dies ist unerwünscht.Fire protection doors are usually made of sheet steel with insulating inserts and a steel frame provided for reasons of stability. Such steel doors are high. heat-resistant and stable against burning, but the high thermal conductivity of steel means that the door side facing away from the fired side quickly heats up. This is undesirable.

Ein Türblatt aus Holz brennt zwar im Laufe der Zeit durch, doch geschieht dies in der Türblattfläche verhältnismäßig langsam, so daß die erforderlichen Standzeiten gegen Durchbrennen erreichbar sind. Holz hat eine geringe Wärmeleitfähigkeit, so daß der vorerwähnte Nachteil einer hohen Erhitzung der der befeuerten Seite abgewandten Türseite nicht auftritt. Ein Türblatt aus Holz brennt allerdings an den Türblattecken und später auch im Bereich der Türberandung wesentlich schneller ab als in der Fläche; aufgrund des verhältnismäßig hohen Feuchtegehaltes zieht sich darüberhinaus ein Türblatt aus Holz bzw. unter Verwendung von holzgefertigtem Werkstoff, insbesondere Spanplattenmaterial,zusammen, so daß die Gefahr einer Spaltbildung zwischen der Türblattberandung und dem umgebenden Zargenbereich auftritt, durch welchen Spalt das Feuer durchgreifen kann.A wooden door leaf burns out over time, but this happens relatively slowly in the door leaf surface, so that the necessary downtime can be achieved against burning. Wood has a low thermal conductivity, so that the aforementioned disadvantage of high heating of the side of the door facing away from the fired side does not occur. However, a wooden door leaf burns much faster at the door leaf corners and later also in the area of the door edge than in the area; Due to the relatively high moisture content, a door leaf made of wood or using wood-made material, in particular chipboard material, contracts, so that there is a risk of a gap forming between the edge of the door leaf and the surrounding frame area, through which gap the fire can penetrate.

Es ist Aufgabe der Erfindung, ein Feuerschutztürblatt aus Holz bzw. holzähnlichem Werkstoff, insbesondere Spanplattenmaterial, zur Verfügung zu stellen, bei welchem die Abbrandgefahren an den gefährdeten Randbereichen vermieden und die Gefahr der Bildung von Spalten zum Zargenbereich hin möglichst ausgeschaltet wird.It is an object of the invention to provide a fire protection door leaf made of wood or a material similar to wood, in particular chipboard material, in which the risk of burns off at the endangered edge areas avoided and the risk of gaps forming towards the frame area is eliminated as far as possible.

Ausgehend von einer Feuerschutztüre mit den Merkmalen des Oberbegriffes des Anspruches 1 wird diese Aufgabe erfindung - gemäß durch dessen Kennzeichen gelöst.Starting from a fire protection door with the features of the preamble of claim 1, this object is achieved - according to its characteristics.

Je nach Anforderung an die Feuerfestigkeit der Tür kann es genügen, die Eckbereiche mit Hilfe der erfindungsgemäßen Isolierschicht bzw. -schichten zu schützen. In bevorzugter Ausführung wird der Randbereich der Tür zumindest teilweise umlaufend, insbesondere aber voll umfänglich mit einer oder mehreren Isolierschichten versehen. Durch diese Isolierschichten erreicht man, daß der Abbrand an den Ecken bzw. Randbereichen zwar stattfinden kann, die Isolierschichten aber den ursprünglichen Torblattumfang aufrechterhalten, so daß für die Standfestigkeit gegen Durchbrennen der Tür die innerhalb der Isolierschicht bzw. -schichten verbleibende Türfläche nach Maßgabe des wesentlich langsamer stattfindenden Flächendurchbrandes erhalten bleibt und eine Spaltbildung zum Zargenrahmen hin nicht platzgreift.Depending on the fire resistance of the door, it may be sufficient to protect the corner areas with the help of the insulating layer or layers according to the invention. In a preferred embodiment, the edge region of the door is provided with one or more insulating layers at least partially all around, but in particular over the entire circumference. These insulating layers ensure that the burn-off can take place at the corners or edge areas, but the insulating layers maintain the original door leaf circumference, so that the door surface remaining within the insulating layer or layers is essentially resistant to burning through the door slower burn-through is retained and gap formation towards the frame frame does not take up space.

Es können mehrere, hinsichtlich der Türblattdichte hintereinander angeordnete Isolierschichten vorgesehen werden, so beispielsweise beidseits des Türblattes und insbesondere derart, daß die Isolierschichten jeweils mit der zugeordneten Türblattfläche bündig abschließen. In bevorzugter Ausführung werden eine oder mehrere Nuten vom Randbereich der Tür her parallel zur Türblattebene in den Randbereich des Holztürblattes eingebracht, in welche eine bzw. mehrere Isolierschichten eingelagert werden. Insbesondere kann eine etwa in der Mitte des Türblattes eingebrachte Nut dieser Art vorgesehen werden, in welche eine Isolierschicht, insbesondere aus Asbestzement, eingelagert wird.A plurality of insulating layers arranged one behind the other with regard to the door leaf density can be provided, for example on both sides of the door leaf and in particular in such a way that the insulating layers are each flush with the assigned door leaf surface. In a preferred embodiment, one or more grooves are made from the edge region of the door parallel to the door leaf level in the edge region of the wooden door leaf, in which one or more insulating layers are embedded. In particular, a groove of this type can be provided approximately in the middle of the door leaf, into which an insulating layer, ins special made of asbestos cement.

Es ist grundsätzlich möglich, in an sich bekannter Weise die der Türblattberandung zugewandte Seite der Zarge mit sogenannten Brandschutzstreifen zu versehen, die unter Hitzeeinwirkung aufquellen bzw. aufschäumen, beispielsweise aus Natriumsilikat. In bevorzugter Ausführung der Erfindung werden ein oder mehrere solcher Brandschutzstreifen im Randbereich des Türblattes vorgesehen, insbesondere in eine Ausnehmung eingelagert, die den randaußenseitigen Bereich der die Isolierschicht enthaltenden Nut bzw. Nuten abdeckt. Die Nut bzw. Nuten und gegebenenfalls die darüber angeordneten Brandschutzstreifen werden vorzugsweise mit einer Abdeckung, beispielsweise einem dickeren Sperrfurnier, außenrandseitig abgedeckt, so daß die erfindungsgemäßen Brandschutzmaßnahmen nach außen nicht in Erscheinung treten.It is fundamentally possible, in a manner known per se, to provide the side of the frame facing the door leaf edge with so-called fire protection strips which swell or foam under the action of heat, for example made of sodium silicate. In a preferred embodiment of the invention, one or more such fire protection strips are provided in the edge region of the door leaf, in particular embedded in a recess which covers the edge-outside region of the groove or grooves containing the insulating layer. The groove or grooves and possibly the fire protection strips arranged above are preferably covered with a cover, for example a thicker barrier veneer, on the outside edge so that the fire protection measures according to the invention do not appear on the outside.

In weiterer Ausgestaltung der Erfindung kann auch eine Feuerschutztür mit einer Türfüllung, beispielsweise aus einer feuerbeständigen Verglasung, zur Verfügung gestellt werden, bei der also lediglich der Rahmen um die Türfüllung herum aus Holz bzw. holzähnlichem Werkstoff besteht. In diesem Falle sind sowohl der innere als auch der äußere Randbereich dieses Holzrahmens in vorgeschilderter Weise geschützt. Dabei empfiehlt es sich, zumindest den inneren Randbereich des Rahmens mit zwei Isolierschichten zu versehen, die jeweils in Ausnehmungen im Außenrandbereich des Rahmens vorgesehen sind. Diese beiden Isolierschichten werden vorzugsweise durch eine den Holzrahmen durchgreifende Verschraubung miteinander verbunden und in ihrer Lage gehalten, insbesondere durch eine Hülsenschraube. Um den Wärmedurchtritt durch die die Türdicke durchgreifende Schraubverbindung abzufangen, werden vorzugsweise Abdeckungen vorgesehen, die die Schrauben übergreifen und einen ästhetisch einwandfreien Abschluß zu der Türfüllung einerseits und zu dem Holzrahmen andererseits bewirken können. Diese Abdeckungen, beispielsweise aus Aluminiumprofilen, werden über Klipp-Verbindungen aufgebracht, so daß nach außen keine Befestigungseinrichtungen für diese Profile in Erscheinung treten.In a further embodiment of the invention, a fire protection door with a door panel, for example made of fire-resistant glazing, can also be provided, in which case only the frame around the door panel consists of wood or wood-like material. In this case, both the inner and the outer edge area of this wooden frame are protected in the manner described. It is advisable to provide at least the inner edge area of the frame with two insulating layers, which are each provided in recesses in the outer edge area of the frame. These two insulating layers are preferably connected to one another by a screw connection penetrating the wooden frame and held in position, in particular by a sleeve screw. In order to absorb the passage of heat through the screw connection penetrating through the door thickness, covers are preferably provided which overlap the screws and provide an aesthetically perfect finish to the Door panel on the one hand and to the wooden frame on the other hand. These covers, for example made of aluminum profiles, are applied via clip connections, so that no fastening devices for these profiles appear on the outside.

Weitere Ausgestaltungen der Erfindung ergeben sich aus Unteransprüchen in Verbindung mit den in der Zeichnung wiedergegebenen Ausführungsbeispielen, auf die besonders Bezug genommen wird und deren nachstehende Beschreibung die Erfindung näher erläutert. Es zeigen:

  • Figur 1 eine Teildarstellung einer Feuerschutztür aus einer Spanplatte mit in den Eckbereichen eingebrachten Isolierschichten;
  • Figur 2 einen Teilquerschnitt durch den Rand- und benachbarten Zargenbereich zur Verdeutlichung der Anordnung einer Isolierschicht, die rund um den Randbereich des Türblattes geführt ist;
  • Figur 3 eine Teilquerschnittsdarstellung durch den Randbereich eines Spanplattentürblattrahmens mit einer Türfüllung aus einer Verglasung.
Further refinements of the invention result from subclaims in connection with the exemplary embodiments shown in the drawing, to which particular reference is made and the description below of which explains the invention in more detail. Show it:
  • Figure 1 is a partial view of a fire door made of a chipboard with insulation layers introduced in the corner areas;
  • Figure 2 shows a partial cross section through the edge and adjacent frame area to illustrate the arrangement of an insulating layer which is guided around the edge area of the door leaf;
  • Figure 3 is a partial cross-sectional view through the edge region of a chipboard door leaf frame with a door panel from a glazing.

Die Teildarstellung eines Feuerschutztürblattes gemäß Figur 1 zeigt ein Türblatt 1 aus einem Spanplattenwerkstoff handelsüblicher Art. In den beiden oberen Eckbereichen sind vom Randbereich her parallel zur Türblattebene verlaufend eingebrachten Nuten dreieckförmige Isolierschichten 2 aus Asbestzement eingebracht. Die Schichten können dort verklebt sein. In nicht dargestellter Weise wird durch beispielsweise ein Sperrfurnier die Brandseite der Tür abgedeckt, so daß die Isolierschichten 2 nicht zu sehen sind.The partial representation of a fire protection door leaf according to FIG. 1 shows a door leaf 1 made of a chipboard material of a commercial type. In the two upper corner areas, triangular insulating layers 2 made of asbestos cement are introduced from the edge area parallel to the door leaf plane. The layers can be glued there. In a manner not shown, the fire side of the door is covered by, for example, a blocking veneer, so that the Insulating layers 2 are not visible.

Im Falle der Befeuerung der Tür sind die Eckbereiche des Türblattes in erster Linie gefährdet. Dort brennt das Holz ab, die Isolierschichten verhindern jedoch eine entsprechend Spaltbildung und halten das Feuerab, so daß die Tür dem Feuer standhält, bis die weitaus langsamer erfolgende Durchbrennung durch den flächigen Türbereich erfolgt.If the door is lit, the corner areas of the door leaf are primarily at risk. The wood burns there, but the insulating layers prevent the formation of gaps and keep the fire out, so that the door can withstand the fire until it burns much more slowly through the flat door area.

Die Teilquerschnittdarstellung durch ein Spanplatten-Feuerschutztürblatt 1 gemäß Figur 2 ist mit einer rings um den Randbereich geführten Isolierschicht 3 versehen, die in eine mittig vom Rand her zum Türblattinneren hin geführten Nut 4 eingelagert ist. Selbstverständlich können auch mehrere in Türblattebene parallele Nuten vorgesehen sein, in welcher entsprechend viele parallele Isolierschichten eingebracht i sind. Randseitig ist die Nut 4 durch eine Aussparung 5 erweitert, in welche ein Brandschutzstreifen 6 aus einem bei Hitzeinwirkung aufschäumendem Material eingelagert ist. Die Nut 4 bzw. die Ausnehmung 5 mit den eingelagerten Werkstoffen 3 und 6 wird stirnaußenrandseitig von einem Sperrfurnier 7 abgedeckt, so daß die Isolierschicht 3 bzw. der Brandstreifen 6 in seiner Lage gehalten und abgedeckt wird. Im Erhitzungsfalle schäumt zunächst der Brandstreifen 6 auf und drückt das Sperrfurnier auf die Zarge 8 zu, so daß der Spalt zwischen dem Türblatt und der Zarge verschlossen wird.The partial cross-sectional view through a chipboard fire protection door leaf 1 according to FIG. 2 is provided with an insulating layer 3 which runs around the edge region and is embedded in a groove 4 which is guided centrally from the edge to the interior of the door leaf. Of course, a plurality of parallel grooves in the door leaf plane can also be provided, in which a corresponding number of parallel insulating layers i are introduced. At the edge, the groove 4 is widened by a recess 5, in which a fire protection strip 6 made of a material that foams up when exposed to heat is embedded. The groove 4 or the recess 5 with the embedded materials 3 and 6 is covered on the outside edge side by a blocking veneer 7, so that the insulating layer 3 or the fire strip 6 is held in its position and covered. In the event of heating, the fire strip 6 first foams and presses the blocking veneer onto the frame 8, so that the gap between the door leaf and the frame is closed.

Die Teilquerschnittdarstellung eines Türblattes mit Holzrahmen 9 und einer als Türfüllung von diesem umgebenen Verglasung 10 zeigt zunächst wieder im Außenrandbereich des Türrahmens 9 eine Isolierschicht 3, wie sie im Zusammenhang mit Figur 2 geschildert wurde.The partial cross-sectional view of a door leaf with a wooden frame 9 and a glazing 10 surrounded as a door panel initially shows an insulating layer 3 in the outer edge region of the door frame 9, as was described in connection with FIG. 2.

Die Verglasung 10 besteht aus zwei Glasscheiben, zwischen denen ein Gel eingelagert ist. Bei Befeuerung wird die dem Feuer zugewandte Glasscheibe zerstört, worauf das Gel abschmilzt bzw. abbrennt. Auf diese Weise erreicht man eine genügende Standfestigkeit gegen Befeuerung.The glazing 10 consists of two glass panes, between which a gel is embedded. When fired, the glass pane facing the fire is destroyed, whereupon the gel melts or burns off. In this way, sufficient stability against firing is achieved.

Im Innenrandbereich des Holzrahmens 9 sind beidseits außen Ausnehmungen 11 vorgesehen, in welche Isolierschichten 12 eingelegt sind. Die Isolierschichten werden mit Hilfe von Schrauben 13 an dem Rahmen gehalten, die die Isolierschichten 12 und den inneren Randbereich des Rahmens im Bereich der Ausnehmungen 11 durchgreifen. Diese Schrauben sind vorzugsweise als Hülsenschrauben ausgebildet und aufgrund ihrer Ausbildung aus Metall wärmeleitend. Aus diesem Grunde werden Abdeckungen 14 vorgesehen, die beidseits des Türblattes die Schraubenenden mit Abstand übergreifen, so daß eine Isolierwirkung gegeben ist. Die Abdeckungen - beispielsweise aus Aluminiumprofilen - sind in nicht dargestellter Weise durch Klammerhalterungen an dem Türblatt bzw. den Isolierschichten 12 gehalten und übergreifen in ihren rahmenseitigen und verglasungs seitigen Endbereichen die Isolierschichten 12 und liegen an dem Rahmen 9 bzw. der Verglasung 10 - im letzteren Falle über eine Kunststoffleiste 15 - an. Damit wird eine ästhetisch einwandfreie Erscheinungsform sichergestellt.In the inner edge region of the wooden frame 9, recesses 11 are provided on both sides on the outside, in which insulating layers 12 are inserted. The insulating layers are held on the frame with the aid of screws 13 which pass through the insulating layers 12 and the inner edge region of the frame in the region of the recesses 11. These screws are preferably designed as sleeve screws and are thermally conductive due to their metal construction. For this reason, covers 14 are provided which overlap the screw ends on both sides of the door leaf at a distance, so that there is an insulating effect. The covers - for example made of aluminum profiles - are held in a manner not shown by clamp holders on the door leaf or the insulating layers 12 and overlap the insulating layers 12 in their frame-side and glazing-side end regions and lie on the frame 9 or the glazing 10 - in the latter case via a plastic strip 15 -. This ensures an aesthetically perfect appearance.

Auch im letzten Ausführungsbeispiel werden jeweils die Rand- bzw. Eckbereiche, die ansonsten der Befeuerung wenig standhalten, durch Isolierschichten 3 bzw. 12 ge- schützt.Also in the last embodiment, each of the edge or corner regions, the little withstand otherwise the firing, ge by insulating layers 3 and 12 - protects.

Durch diese Maßnahmen läßt sich eine Feuerschutztür aus Holz, insbesondere aus Spanplattenmaterial zur Verfügung stellen, die erst dann durchbrennt, wenn sich das Feuer durch die Türfläche bzw. Rahmenfläche selbst hindurchfrißt.These measures make it possible to provide a fire door made of wood, in particular chipboard material, which only burns when the fire is out eats through the door surface or frame surface itself.
