Description
VERBUNDPLATTE ZUM BRANDSCHUTZCOMPOSITE PANEL FOR FIRE PROTECTION
Die Erfindung betrifft eine Verbundplatte zum Brandschutz, bestehend aus einer Dämmstoffschicht und einer Brandschutzschicht oder -■ platte sowie einer Nut-Federverbindung in der Dämmstoffschicht zur Verbindung der Verbundplatten in den Stoßfugen und einer zumindest an zwei Stoßfugen und zumindest auf der Seite der Brandschutzschicht ausgebildeten zweiten Nut-Federverbindung.The invention relates to a composite panel for fire protection, consisting of an insulating layer and a fire protection layer or panel as well as a tongue and groove connection in the insulating layer for connecting the composite panels in the butt joints and a second tongue and groove connection formed at least on two butt joints and at least on the side of the fire protection layer.
Eine gattungsgemäße Verbundplatte zum Brandschutz ist bereits aus der DE-OS 43 37 878 Al vom gleichen Anmelder bekannt. Die Verbundplatte nach der DE-OS 43 37 878 Al weist ebenso eine Dämmstoffschicht aus Polyurethan oder Polystyrol und eine mit ihr verbundene Brandschutzschicht aus einem feuerfesten Material auf. Die Verbundplatten werden stirnseitig über eine Nut-Feder-Verbindung in der Dämmstoffschicht sowie über eine Verbundfeder mit einer feuerfesten Brandschutzschicht, welche in entsprechende Aussparungen in der Dämmstoffschicht gesteckt werden kann, miteinander verbunden .A generic composite panel for fire protection is already known from DE-OS 43 37 878 Al by the same applicant. The composite panel according to DE-OS 43 37 878 Al also has an insulating layer made of polyurethane or polystyrene and a fire protection layer made of a fireproof material connected to it. The composite panels are connected to one another at the front via a tongue and groove connection in the insulating layer and via a composite tongue with a fireproof fire protection layer, which can be inserted into corresponding recesses in the insulating layer.

Diese Verbundplatte weist jedoch den Nachteil auf, daß das Einführen der Verbundfeder in die entsprechende Aussparung
in der Dämmstoffschicht bei der Montage einen aufwendigen
Arbeitsschritt bedeutet.
5However, this composite panel has the disadvantage that inserting the composite spring into the corresponding recess in the insulation layer during assembly is a complex work step.

Bei der Montage tritt die weitere Schwierigkeit auf, daß die Verbundfeder aus relativ hartem Material nun beim Zusammenstecken der Verbundplatten in die gegenüberliegende Aussparung in der Dämmstoffschicht der gegenüberliegenden Platte eingeführt werden muß. Die Aussparung in der Dämmstoffschicht ist L-förmig ausgebildet, so daß eine Nutwand und der Nutboden aus der Dämmstoffschicht besteht und die gegenüberliegende Nutwand durch die Brandschutzschicht gebildet wird. Treten nun beim Zusammenstecken der Verbundplatten Maßungenauigkeiten auf, oder ist der Untergrund nicht ganz eben, so trifft die relativ harte Verbundfeder auf die relativ weiche Dämmstoffschicht und es kommt beim Zusammenstecken zu Abrissen an der Ecke Nutwand-Stirnseite der Dämmstoffschicht und die abgerissenen Stücke verhindern ein formschlüssiges Zusammenschieben der Verbundplatten.Another difficulty during assembly is that the composite spring made of relatively hard material must now be inserted into the opposite recess in the insulation layer of the opposite panel when the composite panels are put together. The recess in the insulation layer is L-shaped, so that one groove wall and the groove base consist of the insulation layer and the opposite groove wall is formed by the fire protection layer. If there are dimensional inaccuracies when putting the composite panels together, or if the surface is not completely flat, the relatively hard composite spring hits the relatively soft insulation layer and when putting them together, tears occur at the corner of the groove wall and the front side of the insulation layer and the torn pieces prevent the composite panels from being pushed together in a form-fitting manner.
Derartige Verbundplatten zum Brandschutz müssen unter Feuereinwirkung eine bestimmte Mindeststandzeit aufweisen. Derartige Mindeststandzeiten sind in der DIN 4102 verankert.Such composite panels for fire protection must have a certain minimum service life when exposed to fire. Such minimum service lives are anchored in DIN 4102.
Die Verbundplatte nach der DE-OS 43 37 878 hat des weiteren den Nachteil, daß sie unter Brandeinwirkung eine zu geringe Mindestandzeit aufweist, um die Erfordernisse der in der DIN 4102 verankerten Feuerwiderstandsklasse F30-B zu erfüllen. Der Schwachpunkt'dieser Verbundplatten tritt hier an den Stoßfugen auf. Werden die montierten Verbundplatten mit Hitze beaufschlagt, so beginnt nach längerer Hitzeeinwirkung die Dämmstoffschicht zu verkohlen und das Material ziehtThe composite panel according to DE-OS 43 37 878 also has the disadvantage that it has too short a minimum service life under fire exposure to meet the requirements of the fire resistance class F30-B as laid down in DIN 4102. The weak point of these composite panels is the butt joints. If the assembled composite panels are exposed to heat, the insulation layer begins to char after prolonged exposure to heat and the material shrinks.

sich zusammen. Durch das Verkohlen und die Kontraktion der Dämmstoffschicht verliert die Nut-Federverbindung in der Dämmstoffschicht sowie die Verbundfeder ihre kraftschlüssige Wirkung. Die Verbundfeder stellt nach der Verkohlung und der Kontraktion der Dämmstoffschicht lediglich eine lose Abdichtung der Stoßfuge dar und kann die Verbundplatten nicht mehr kraftschlüssig zusammenhalten. Die Verbundplatten können sich somit verschieben und die Stoßfugen beginnen aufzuklaffen, wodurch die brandschützende Funktion der Verbundplatten gemindert oder sogar aufgehoben ist.come together. Due to the carbonization and contraction of the insulation layer, the tongue and groove connection in the insulation layer and the composite tongue lose their force-locking effect. After the carbonization and contraction of the insulation layer, the composite tongue only represents a loose seal of the butt joint and can no longer hold the composite panels together in a force-locking manner. The composite panels can therefore shift and the butt joints begin to gape, which reduces or even eliminates the fire-protection function of the composite panels.
Es ist ferner aus der G 73 32 763 eine Bauplatte für feuerhemmende Wanddecken oder Dachausbildungen bekannt, welche aus einem Isolierstoff besteht, der beidseitig mit Deckschichten aus koloriertem Stahlblech umgeben ist. Die Längsseiten der Bauplatten sind entweder als Nut oder als Feder ausgebildet, wobei nutseitig eine Schulterfeder aus thermisch isolierendem Material aufgenommen ist. Die Schulterfeder greift beim Zusammenstecken der Bauplatten in eine U-förmige Aussparung am federseitigen Ende der Bauplatte. Die Schulterfeder wird über Klammern am nutseitigen Ende der Bauplatte befestigt. Der Zwischenraum, welcher beim Zusammenstecken der Bauplatten entsteht, kann mit einer Dichtmasse bzw. mit Füllprofilen ausgefüllt sein.Furthermore, from G 73 32 763 a building board for fire-retardant wall ceilings or roof structures is known, which consists of an insulating material that is surrounded on both sides by cover layers made of colored sheet steel. The long sides of the building boards are designed either as a groove or as a tongue, with a shoulder spring made of thermally insulating material being accommodated on the groove side. When the building boards are put together, the shoulder spring engages in a U-shaped recess on the tongue-side end of the building board. The shoulder spring is attached to the groove-side end of the building board using clips. The gap that is created when the building boards are put together can be filled with a sealing compound or with filling profiles.
Nachteilig an dieser Konstruktion ist die aufwendige Herstellung bei der das Isoliermaterial der Bauplatten mit speziell gebogenem koloriertem Stahlblech umgeben werden muß. Ein weiterer Nachteil ist, daß aufgrund der Verwendung von koloriertem Stahlblech die Nut-Federverbindung nicht exakt abdichtend ausgestaltet werden kann, und daß somit Hilfsvorkehrungen, wie die Verwendung von Dichtmasse und Füllprofi-The disadvantage of this construction is the complex manufacturing process, in which the insulating material of the building panels must be surrounded by specially bent colored sheet steel. Another disadvantage is that due to the use of colored sheet steel, the tongue and groove connection cannot be designed to seal exactly, and that auxiliary measures, such as the use of sealing compound and filling profiles, are therefore not necessary.

len notwending sind. Ferner ist nachteilig, daß die feuerfeste Schulterfeder mittig in der Bauplatte angeordnet ist und somit bei Brandeinwirkung keinen Hitzeschild im Fugenbereich gegenüber dem umgebenden Isolierstoff darstellt. Auf der schmäleren Seite der Schulterfeder ist weder diese noch die Nut in der sie aufgenommen ist mit koloriertem Stahlblech verkleidet. Bei Hitzeeinwirkung verkohlt auch bei dieser Konstruktion das Isoliermaterial und zieht sich zusammen oder beginnt zu schmelzen. Um ein Heraustreten des Isolierstoffs aus der Fuge zu vermeiden, müssen in der Fuge zusätzlich Füllprofile angeordnet werden, bzw. die gesamte Fuge mit Dichtmasse abgedichtet werden. Die Schulterfeder stellt nach Hitzeeinwirkung und Kontraktion des Isolierstoffes keine kraftschlüssige Verbindung der Bauplatten mehr dar.len are necessary. Another disadvantage is that the fireproof shoulder spring is arranged in the middle of the building board and therefore does not provide a heat shield in the joint area against the surrounding insulating material in the event of a fire. On the narrower side of the shoulder spring, neither this nor the groove in which it is accommodated is covered with colored sheet steel. When exposed to heat, the insulating material in this construction also chars and contracts or begins to melt. In order to prevent the insulating material from escaping from the joint, additional filling profiles must be arranged in the joint or the entire joint must be sealed with sealing compound. After exposure to heat and contraction of the insulating material, the shoulder spring no longer provides a force-fit connection between the building boards.
Auch die äußere Nut-Federverbindung verliert ihre kraftschlüssige Wirkung, da dem Stahlblech durch die Kontraktion des Isolierstoffes die Gegenkraft fehlt. Die Bauplatte nach der G 733 27 63 weist somit einen komplizierten und kostenintensiven Aufbau auf und ihre Fugenausbildung erfüllt höchstwahrscheinlich nicht die Anforderungen der in der DIN 4102 verankerten Feuerwiderstandsklasse F 30/B.The external tongue and groove connection also loses its force-locking effect, as the steel sheet lacks the counterforce due to the contraction of the insulating material. The building board according to G 733 27 63 therefore has a complicated and cost-intensive structure and its joint design most likely does not meet the requirements of the fire resistance class F 30/B anchored in DIN 4102.
Gemäß dem dargelegten Stand der Technik ist es Aufgabe der Erfindung, eine Verbundplatte zum Brandschutz der eingangs genannten Art derart weiterzubilden, daß bei einfachem Aufbau und einfacher Montage die Mindeststandzeit unter Brandeinwirkung derart erhöht wird, so daß die Verbundplatte die Erfordernisse der in der DIN 4102 verankerten Feuerwiderstandsklasse1 F 30/B erfüllt.According to the state of the art presented, it is the object of the invention to further develop a composite panel for fire protection of the type mentioned at the beginning in such a way that, with simple construction and simple assembly, the minimum service life under the influence of fire is increased to such an extent that the composite panel meets the requirements of fire resistance class 1 F 30/B anchored in DIN 4102.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zumindest die der Dämmstoffschicht zugewandten WandabschnitteThis object is achieved according to the invention in that at least the wall sections facing the insulation layer

Die Nut der zweiten Nut-Federverbindung ist günstigerweise aus Brandschutzstreifen aufgebaut, wobei ein Brandschutzstreifen als Nutwand und ein kürzerer zweiter als Nutboden dient. Die zweite Nutwand wird durch die Brandschutzschicht gebildet. Durch diesen Aufbau wird eine stabile Nut aus feuerfestem Material geschaffen, welche zum einen eine leichte Montage der Verbundplatten untereinander erlaubt, und zum anderen auch unter längerer Hitzeeinwirkung eine kraftschlüssige Nut-Federverbindung zwischen den Verbundplatten gewährleistet.The groove of the second tongue and groove connection is advantageously constructed from fire protection strips, with one fire protection strip serving as the groove wall and a shorter second one as the groove base. The second groove wall is formed by the fire protection layer. This construction creates a stable groove made of fireproof material, which on the one hand allows the composite panels to be easily assembled with one another and on the other hand ensures a force-locking tongue and groove connection between the composite panels even under prolonged exposure to heat.
Vorteilhafterweise ist die zweite Nut-Federverbindung in einer L-förmigen Aussparung zwischen der Dämmstoffschicht und der Brandschutzschicht angeordnet.Advantageously, the second tongue and groove connection is arranged in an L-shaped recess between the insulation layer and the fire protection layer.
Die Feder der zweiten Nut-Federverbindung ist hierbei günstigerweise als feuerbeständige Brandschutzfeder ausgebildet. Die Brandschutzfeder bildet den feuerfesten Übergang der Verbundplatten im Stoßbereich.The tongue of the second tongue and groove connection is advantageously designed as a fire-resistant fire protection tongue. The fire protection tongue forms the fireproof transition of the composite panels in the joint area.
Die Brandschutzfeder ist günstigerweise über Schnellbauschrauben, Klammern o.dgl. mit der Dämmstoffschicht und der Brandschutzschicht verbunden.The fire protection spring is preferably connected to the insulation layer and the fire protection layer using drywall screws, clamps or similar.
Ebenso ist es günstig die Brandschutzstreifen, welche die Nut bilden, ebenfalls über Schnellbauschrauben, Klammern o.dgl. mit der Dämmstoffschicht, der Brandschutzschicht und auch untereinander zu verbinden. Dieses Festlegen der Brandschutzfeder sowie der Brandschutzstreifen erfolgt werksei-It is also advisable to connect the fire protection strips that form the groove to the insulation layer, the fire protection layer and to each other using drywall screws, clamps or similar. This fixing of the fire protection tongue and the fire protection strips is carried out at the factory.

Vorteilhaft ist es, die Maße der Brandschutzfeder und der Nut der zweiten Nut-Federverbindung so zu wählen, daß nach der Motage die Brandschutzfeder kraftschiüssig in der aus Brandschutzstreifen und Brandschutzschicht aufgebauten Nut gehalten ist.It is advantageous to select the dimensions of the fire protection tongue and the groove of the second tongue-and-groove connection so that after assembly the fire protection tongue is held firmly in the groove made up of the fire protection strip and fire protection layer.
Des weiteren ist vorteilhaft, daß die Verbundplatten nach der Montage beidseitig eine ebene Oberfläche aufweisen. Es wird dadurch ein streich-, tapezier- und putzfähige Schicht geschaffen.Another advantage is that the composite panels have a flat surface on both sides after installation. This creates a layer that can be painted, wallpapered and plastered.
In einem weiteren Ausführungsbeispiel ist es günstig zwischen der Dämmstoffschicht und der Brandschutzschicht eine Zusatzschicht anzuordnen.In a further embodiment, it is advantageous to arrange an additional layer between the insulation layer and the fire protection layer.

Die Nut dieser ersten Nut-Federverbindung 4 ist eine U-förmige Aussparung in der Dämmstoffschicht 1 und die Feder ist ein entsprechender Vorsprung in der gegenüberliegenden Verbundplatte und besteht ebenfalls aus dem Material der Dämmstoffschicht 1. Nut und Feder dieser ersten Nut-Federverbindung 4 sind so ausgebildet, daß sie nach dem Zusammenstecken eine kraftschlüssige Klemm-Preßverbindung bilden.A first tongue and groove connection 4 is formed in the insulation layer 1, whereby this is arranged approximately in the middle of the composite panel. The groove of this first tongue and groove connection 4 is a U-shaped recess in the insulation layer 1 and the tongue is a corresponding projection in the opposite composite panel and is also made of the material of the insulation layer 1. The tongue and groove of this first tongue and groove connection 4 are designed in such a way that after they are put together they form a force-locking clamp-press connection.
An der Seite der Verbundplatten, an welcher die Brandschutzschicht 2 angebracht ist, ist jeweils in der Dämmstoffschicht nutseitig eine Aussparung 6 und federseitig eine Aussparung 7 zwischen Dämmstoffschicht 1 und Brandschutzschicht 2 vorgesehen. In diesen Aussparungen 6,7 ist eine zweite Nut-Federverbinduhg 5 angeordnet, welche aus einer Brandschutzfeder 8 und Brandschutzstreifen 9 und 10 besteht. Die Nut der zweiten Nut-Federverbindung 5 wird aus der Brandschutzschicht 2 als erster Nutwand, einem Brandschutzstreifen 9 als Nutboden und Abstandhalter für einen weiteren Brandschutzstreifen 10, welcher ebenfalls als Nutwand dient, gebildet. Der Brandschutzstreifen 9 ist zwischen der Brandschutzschicht 2 und dem Brandschutzstreifen 10 angeordnet und etwas kürzer als der Brandschutzstreifen 10 ausgebildet. Die Brandschutzschicht 2, sowie die Brandschutzstreifen 9 und 10 sind in diesem Ausführungsbeispiel über zwei Schnellbauschrauben 11 miteinander verbunden, wobei die beidenOn the side of the composite panels to which the fire protection layer 2 is attached, a recess 6 is provided in the insulation layer on the groove side and a recess 7 is provided on the tongue side between the insulation layer 1 and the fire protection layer 2. A second tongue-and-groove connection 5 is arranged in these recesses 6,7, which consists of a fire protection tongue 8 and fire protection strips 9 and 10.
