Abstract

The door has a continuous or frame-like filling (1) of less solid material set stabilised by a solid frame (6) whose socket is made of laminated wood veneer. Several individual veneers can be fixedly glued together on interposed layers (8) running at right angles to the plane of the door panel. The adhesive layers can each run parallel to the outer edge (2) set closest to it. The glue on the layers can be based on phenol or "Melamin" (RTM) resins. The veneer layer can be enclosed round its outer sides by one or more cover strips.

Description

Die Erfindung betrifft ein Feuer- und/oder Rauchschutztürblatt auf der Basis von Holzwerkstoffen mit einer durchgehenden oder rahmenartigen Füllung aus weniger festen Werkstoff, die zu ihren Außenrändern oder zumindest zu ihren längsseitigen Außenrändern hin gesehen von einem festen Rahmenwerkstoff stabilisierend eingefaßt ist.The invention relates to a fire and / or smoke protection door leaf on the basis of wood-based materials with a continuous or frame-like filling made of less solid material, which is bordered by a solid frame material as seen towards its outer edges or at least towards its longitudinal outer edges.

Derartige Feuer- und/oder Rauchschutztürblätter bekannter Art sind bspw. wenigstens für den Brandschutzbereich T30 bestimmt, d.h. sie halten nach entsprechender DIN-Bestimmung einer Brandbeaufschlagung von einer Seite entsprechend Stand. Bekannte Feuer- und/oder Rauchschutztürblätter dieser Art werden aus Spanplatten hergestellt, die jedoch hinsichtlich ihrer Stabilität im Brandbereich nicht ausreichen, um Beschläge ― Bänder, Schlösser, etc. ― dauerhaft zu befestigen. Deshalb hat man die das Türblatt bildende Spanplatte mit einem Massivholzrahmen oder einem Rahmen aus mitteldichtem Faserplattenmaterial eingefaßt, wobei die Rahmen entweder stumpf oder verzahnt an die Spanplatte angeleimt bzw. angetaktet sind.Such fire and / or smoke protection door leaves of known type are intended, for example, at least for the fire protection area T30, ie they withstand fire from one side according to the corresponding DIN regulation. Known fire and / or smoke protection door leaves of this type are made from chipboard which However, in terms of their stability in the fire area, they are not sufficient to permanently fix fittings - hinges, locks, etc. For this reason, the particle board forming the door leaf has been edged with a solid wood frame or a frame made of medium-density fiberboard material, the frames being glued or clocked onto the particle board either blunt or toothed.

Bei Verwendung als Feuerschutztüren weisen die bekannten Feuer- und/oder Rauchschutztürblätter weiterhin einen im Brandfall aufschäumenden Materialstreifenbereich oder streifenförmige Umrahmung auf ― bspw. Palusol ―, der bzw. die die Aufgabe hat, den Fugenbereich zwischen Zarge und Türblatt im Brandfall und damit unter entsprechender Wärmezufuhr zu verschließen. Dafür wird dieser aufschaumfähige Materialstreifenbereich von einem der Zarge zugewandten Deckleistenbereich umgriffen, der also die sichtbare Stirnkante der Tür im Falzbereich bildet und unter Wärmeeinwirkung von dem aufschäumenden Materialstreifenbereich dichtend gegen die Zargen hin gedruckt wird.When used as fire protection doors, the known fire and / or smoke protection door leaves also have a material strip area or strip-shaped frame which foams up in the event of a fire - for example Palusol - which has the task of providing the joint area between the frame and the door leaf in the event of a fire and thus with the appropriate supply of heat to close. For this purpose, this foamable material strip area is encompassed by a cover strip area facing the frame, which therefore forms the visible end edge of the door in the rebate area and is printed sealingly against the frames under the influence of heat from the foaming material strip area.

Obwohl bei der Verwendung von mitteldichtem Faserplattenmaterial gegenüber Massivholz als Rahmenwerkstoff zur Einfassung von Spanholzplatten Vorteile bzgl. Kosten, Be- und Verarbeitbarkeit, gleichbleibender Standfestigkeit der Tür unter Einfluß von Klima- und Brandbedingungen und Vermeidung des Gebrauchs von Tropenhölzern erzielt werden, sind die bisher bekannten gattungsgemäßen Feuer- und/oder Rauchschutztürblätter in feuer- und rauchschutztechnischer Hinsicht noch verbesserungswürdig. Im Brandfall können sich die bekannten Feuer- und/oder Rauchschutztürblätter verbiegen, wodurch im Extremfall Leckagen zwischen Zarge und Feuer- und/oder Rauchschutztürblatt entstehen und die gewünschte Schutzfunktion nicht mehr gegeben ist. Die Tendenz zum Verbiegen des Feuer- und/oder Rauchschutztürblattes wird in der Ausführung als Feuerschutztür noch durch Kräfte verstärkt, die durch den aufschäumenden Materialstreifenbereich auf das Feuer- und/oder Rauchschutztürblatt ausgeübt werden. Dies ist um so mehr der Fall, wenn das Aufschäumen, wie meist, aufgrung unterschliedlich hoher Temperaturen nicht überall gleichmäßig erfolgt. Außerdem ist die Hitzebeständigkeit der bekannten Rahmenmaterialien sehr gering.Although the use of medium-density fiberboard material compared to solid wood as a frame material for edging chipboard panels offers advantages in terms of costs, workability and workability, constant stability of the door under the influence of climate and fire conditions and avoidance of the use of tropical woods, the previously known generic ones are Fire and / or smoke protection door leaves still need improvement in terms of fire and smoke protection. In the event of a fire, the known fire and / or smoke protection door leaves can bend, which in extreme cases causes leaks between the frame and the fire and / or smoke protection door leaves and the desired protective function is no longer provided. The tendency to bend the fire and / or smoke protection door leaf is reinforced in the version as a fire protection door by forces which are exerted on the fire and / or smoke protection door leaf by the foaming material strip area. This is all the more the case if the foaming, as is usually the case, does not take place uniformly everywhere at different temperatures. In addition, the heat resistance of the known frame materials is very low.

Der Erfindung liegt die Aufgabe zugrunde, ein Feuer- und/oder Rauchschutztürblatt der eingangs erwähnten Art mit bezüglich vorgenannten Gesichtspunkten verbesserten brand- und/oder rauchschutztechnischen Eigenschaften zu schaffen.The invention has for its object to provide a fire and / or smoke protection door leaf of the type mentioned with improved fire and / or smoke protection properties with respect to the aforementioned aspects.

Diese Aufgabe wird dadurch gelöst, daß die Einfassung aus festem Rahmenwerkstoff aus Furnierschichtholz besteht.This object is achieved in that the border consists of a solid frame material made of laminated veneer lumber.

Durch die Verwendung von Furnierschichtholz als Rahmenwerkstoff wird eine wesentlich höhere Biegesteifigkeit des erfindungsgemäßen Feuer- und/oder Rauchschutztürblattes gegenüber einem Feuer- und/oder Rauchschutztürblatt mit einem anderem bisher in diesem Bereich verwendeten Rahmenwerkstoff erreicht. Das erfindungsgemäße Feuer- und/oder Rauchschutztürblatt setzt damit einer Verwindung oder Verbiegung im Brandfall und den damit verbundenen Gefahren einen viel höheren Widerstand entgegen. Übertaschenderweise hat sich auch gezeigt, daß Furnierschichtholz eine größere Widerstandsfähigkeit gegenüber Hitze als die bisher verwendeten Rahmenwerkstoffe aufweist. Diese Widerstandsfähigkeit ist auf die zusätzliche Hitzewiderstandsfähigkeit von Leimschichten zwischen einzelnen Furnieren zurückzuführen. Zusätzlich wird durch Verleimen der Furniere, welches üblicherweise unter hohem Druck geschieht, ein gewisser Vergütungseffekt in den Rahmen mit eingebracht.By using laminated veneer lumber as the frame material, the fire and / or smoke protection door leaf according to the invention has a considerably higher bending stiffness than a fire and / or smoke protection door leaf with another frame material previously used in this area . The fire and / or smoke protection door leaf according to the invention thus provides a much higher resistance to twisting or bending in the event of a fire and the associated dangers. Surprisingly, it has also been shown that laminated veneer lumber is more resistant to heat than the frame materials previously used. This resistance is due to the additional heat resistance of glue layers between individual veneers. In addition, by gluing the veneers, which is usually done under high pressure, a certain tempering effect is brought into the frame.

In bevorzugter Ausführung sind einzelne Furniere des Furnierschichtholzes an dazwischenliegenden, rechtwinkelig zu der Türblattebene (der Ebene der Füllung) verlaufenden Verklebungsschichten fest miteinander verleimt. Dadurch sind die Schichten quer zur Biegerichtung angeordnet und setzen so einer Verbiegung einen höheren Widerstand entgegen. In weiter bevorzugter Ausführung verlaufen die Verklebungsschichten jeweils parallel zu den ihnen am nächsten liegenden Außenrändern und somit sozusagen in Umfangsrichtung des Rahmens, was die Biegesteifigkeit weiter erhöht. In weiter bevorzugter Ausführung sind in den Verklebungsschichten zum Verleimen der Furniere Leime aus Phenol- oder Melaminharzen verwendet, welche sich durch eine besonders hohe Widerstandsfähigkeit gegenüber Hitze auszeichnen. Zum Schaffen eines optischen und/oder dichtenden Abschlußes ist das Furnierschichtholz in weiter bevorzugter Ausführung an seiner umfangsmäßig äußeren Seite von einer oder mehreren Deckleisten umgeben.In a preferred embodiment, individual veneers of the laminated veneer lumber are firmly glued to one another at intermediate adhesive layers that run at right angles to the door leaf level (the level of the filling). As a result, the layers are arranged transversely to the bending direction and thus offer greater resistance to bending. In a further preferred embodiment, the adhesive layers each run parallel to the outer edges closest to them and thus, so to speak, in the circumferential direction of the frame, which further increases the bending rigidity. In a further preferred embodiment, glues made of phenolic or melamine resins are used in the adhesive layers for gluing the veneers are characterized by a particularly high resistance to heat. To create an optical and / or sealing closure, the veneer plywood in a further preferred embodiment is surrounded on its circumferential outer side by one or more cover strips.

In weiter bevorzugter Ausführungsform kann zwischen der Deckleiste und dem Rahmenwerkstoff aus Furnierschichtholz ein Werkstoffstreifenbereich angeordnet sein, der unter Wärmeeinwirkung sein Volumen vergrößert und so bei Brandeinwirkung in Schließstellung die Deckleiste in feste Anlage gegen die Zargenstirnseite bringt. Der an sich bekannte Werkstoffstreifenbereich ist gerade bei der Erfindung aufgrund der besonders hohen Biegesteifigkeit des erfindungsgemäßen Feuer- und/oder Rauchschutztürblattes, das somit selbst bei ungleichem Aufschäumen weniger verbogen wird, besonders vorteilhaft.In a further preferred embodiment, a strip of material can be arranged between the cover strip and the frame material made of laminated veneer lumber, which increases its volume under the influence of heat and thus brings the cover strip into firm contact against the frame end face when exposed to fire in the closed position. The material strip area known per se is particularly advantageous in the case of the invention, in particular, because of the particularly high flexural rigidity of the fire and / or smoke protection door leaf according to the invention, which is therefore less bent even when foaming is uneven.

In weiterhin bevorzugter Ausführung sind die Deckleisten, die ein entsprechend geringes Volumen aufweisen, da sie vor allem dem Stirnkantenabschluß und/oder der Fugenabdichtung im Brandfall dienen, die nach Abschluß des Brandes leicht entfernbar sein soll, in Anpassung an die Türblatt- bzw. Zargenkonstruktion glatt oder entsprechend gefalzt ausgebildet. Zur Abdeckung der Großflächen des Türblattes können

Can cover the large areas of the door leaf

Im Rahmen der gezeichneten Ausführungen ist mit 1 ein Kern bestehend aus einer Platte aus Holzwerkstoff, beispielsweise aus einer Holzspanplatte oder wahlweise auch aus mehreren Teilen, wiedergegeben. An den Kern 1 ist an allen vier Außenrändern 2, 3, 4, 5 oder wahlweise auch nur an den längsseitigen Außenrändern 2 und 3 ein Rahmen 6 aus Furnierschichtholz angeleimt, welches aus mehreren Schichten von Furnieren 7 aufgebaut ist, die wiederum an dazwischenliegenden Verklebungsschichten 8 fest miteinander verleimt sind. Das Furnierschichtholz ist so angeleimt, daß die Verklebungsschichten 8 der einzelnen Furniere 7 im rechten Winkel zur Plattenebene liegen. Wie in den einzelnen Figuren dargestellt, verlaufen die Verklebungsschichten 8 dabei parallel zu dem jeweils am nächsten liegenden eingefaßten Außenrand 2, 3, 4, bzw. 5.In the context of the drawings shown, 1 represents a core consisting of a board made of wood-based material, for example a chipboard or optionally also of several parts. A frame 6 made of laminated veneer wood is glued to the core 1 on all four outer edges 2, 3, 4, 5 or optionally only on the longitudinal outer edges 2 and 3, which frame is made up of several layers of veneer 7, which in turn is bonded to the adhesive layers 8 in between are firmly glued together. The laminated veneer lumber is glued in such a way that the adhesive layers 8 of the individual veneers 7 lie at right angles to the plane of the board. As shown in the individual figures, the adhesive layers 8 run parallel to the closest bordered outer edge 2, 3, 4 or 5.

Der Rahmen 6 ist umfangs- oder außenseitig mit einem sogenannten Anleimer 9 als Deckleiste umgeben, der bei den in den Figuren 1 bis 3 gezeigten Ausführungsformen direkt an den Rahmen 6 angeleimt ist. Bei weiteren, in den Figuren 4 bis 6 gezeigten Ausführungsformen ist der Rahmen 6 im Bereich des oberen Außenrandes 4 und/oder der längsseitigen Außenränder 2 und 3 außenseitig von Palusolstreifen 10 umgeben, die unter Wärmeeinfluß aufschäumen und den an den Palusolstreifen 10 befestigten Anleimer 9 gegen die benachbarten Zargenabschnitte drücken, um die geschlossene Tür im Brandfalle insoweit fugendicht abzuschließen. Der aus den Anleimern 9 gebildete Deckleistenrahmen bildet die der Türansicht ausgesetzte Stirnkante des Türblattes. Vor allem im Sinne einer weiteren Fassung und optischen Verbesserung sind die beiden Türblattbreitseiten mit einer sogenannten Absperrung 11 aus Hartfaserplatte oder HDF zuzüglich Oberflächenbeschichtung 12 versehen.The frame 6 is circumferentially or externally surrounded by a so-called band 9 as a cover strip which is glued directly to the frame 6 in the embodiments shown in FIGS. 1 to 3. In further embodiments shown in FIGS. 4 to 6, the frame 6 is in the region of the upper outer edge 4 and / or of the longitudinal outer edges 2 and 3 surrounded on the outside by palusol strips 10, which foam under the influence of heat and press the band 9 attached to the palusol strips 10 against the adjacent frame sections in order to close the closed door in a fire-tight manner in the event of a fire. The cover strip frame formed from the edge bands 9 forms the front edge of the door leaf exposed to the door view. Especially in the sense of a further version and optical improvement, the two broad sides of the door leaf are provided with a so-called barrier 11 made of hardboard or HDF plus surface coating 12.

Bei der Herstellung des Türblattes wird zunächst der Rahmen 6 in der beschriebenen Weise an den Kern 1 angeleimt. An den Rahmen 6 wird dann entweder direkt oder nach Anleimung der Palusolstreifen 10 der Anleimer 9 geleimt. Überstände über die Ebenen der Platte des Kerns 1 werden durch einen sogenannten Kalibrierdurchgang abgeschliffen. Anschließend wird der Kern 1 und der gesamte Aufbau mit der Absperrung 11 aus HDF und der Oberfläche 12 beschichtet, um so das Türblatt für eine Feuer- oder Rauchschutztür oder einer Kombination von beidem zu bilden.When producing the door leaf, the frame 6 is first glued to the core 1 in the manner described. The frame 9 is then glued either directly or after the palusol strips 10 have been glued on. Protrusions over the levels of the plate of the core 1 are ground off by a so-called calibration pass. Subsequently, the core 1 and the entire structure are coated with the barrier 11 made of HDF and the surface 12, so as to form the door leaf for a fire or smoke protection door or a combination of both.

Durch den Rahmenwerkstoff aus Furnierschichtholz wird eine höhere Biegesteifigkeit der Feuer- und/oder Rauchschutztür gegenüber Türblättern mit bisher in diesem Bereich verwendeten Rahmenwerkstoffen erreicht. Maßgeblich für den Einsatz des Türblatts an Feuer- und/oder Rauchschutztüren ist die gegenüber Hitze sehr widerstandsfähige Verleimung der Furniere 7. Hierzu werden Leime auf der Basis von Phenol- oder Melaminharzen verwendet. Zusätzlich wird der Rahmenwerkstoff durch das Verleimen der Furniere 7, das unter hohem Druck geschieht, vergütet. Da der Rahmen 6 aufgrund der Verwendung des Furnierschichtholzes hochfest ist, kann seine umfangsmäßige Abmessung gering, beispielsweise im Bereich um 30 mm, gehalten werden.The frame material made of laminated veneer lumber gives the fire and / or smoke protection door a higher bending stiffness than door leaves with frame materials previously used in this area. Decisive for the use of the door leaf on fire and / or smoke protection doors is the heat-resistant gluing of the veneers 7. Glues based on phenol or melamine resins are used for this. In addition, the frame material is tempered by gluing the veneers 7, which takes place under high pressure. Since the frame 6 is high-strength due to the use of the laminated veneer lumber, its circumferential dimension can be kept small, for example in the range around 30 mm.

Das Türblatt kann für 1-flügelige und 2-flügelige Türen in der Kantengeometrie gefälzt, stumpf und/oder stumpf mit Leibungsfalz, wahlweise auch mit Oberblende gefertigt werden. Das Türblatt kann bei Bedarf auch mit einem Lichtausschnitt versehen werden, der durch ein eingesetztes Brandschutzglas wieder verschlossen wird. Selbstverständlich ist auch eine Ausführung denkbar, bei der der Palusolstreifen 10 zusätzlich oder alleine am Bereich des unteren Außenrandes 5 zwischen Anleimer 9 und Rahmen 6 vorhanden ist.The edge of the door leaf for single-leaf and double-leaf doors can be rebated, blunt and / or blunt with a reveal, optionally with a top panel. If required, the door leaf can also be provided with a light cut-out, which can be closed again by a fire protection glass. Of course, an embodiment is also conceivable in which the palusol strip 10 is additionally or alone present at the area of the lower outer edge 5 between the banding 9 and frame 6.
