Ein Türblatt des beschriebenen Aufbaus ist aus DE 100 22 120 C1 bekannt. Im Brandfall besteht das Problem, dass das Türblatt sich unter der Hitzeeinwirkung verformt und durch den sich aufweitenden Spalt zwischen Türblatt und Türzarge Feuer durchschlägt. Um die in DIN 4102, Teil 5 festgelegten Anforderungen an eine Brandschutztür oder Brandschutzklappe zu erfüllen, müssen in das Türblatt daher Versteifungselemente eingeschweißt und verhältnismäßig dicke Stahlbleche zur Fertigung des Türblattes verwendet werden.A door leaf of the structure described is from DE 100 22 120 C1 known. In the event of a fire, the problem is that Door leaf deforms under the influence of heat and through the widening gap between the door leaf and door frame Fire breaks through. In order to comply with DIN 4102, part 5 Requirements for a fire door or fire damper to meet, must therefore stiffening elements in the door leaf welded and relatively thick steel sheets be used to manufacture the door leaf.

Der Erfindung liegt die Aufgabe zugrunde, durch eine möglichst einfache konstruktive Maßnahme die Verformung des Türblattes im Brandfall zu reduzieren.The invention is based, if possible simple constructive measure the deformation of the To reduce door leaf in the event of fire.

Die Aufgabe wird bei einem Türblatt des eingangs beschriebenen Aufbaus erfindungsgemäß dadurch gelöst, dass der Türfalz mit einem Blähmaterial ausgefüllt ist, welches bei Erhitzung expandiert und dabei den Türfalz aufbiegt. Unter der expandierenden Wirkung des im Türfalz angeordneten Blähmaterials werden die U-förmig abgewinkelten und zum Türfalz umgebogenen Randabschnitte im Brandfall aufgeweitet und gegen die das Türblatt umgebende Türzarge gepresst. Dabei wird das Türblatt in der Türzarge so fest verspannt, das die im Brandfall auftretenden Verformungskräfte aufgenommen werden können und das Türblatt in der Türzarge gerade stehen bleibt. Ein Teil des stark expandierenden Blähmaterials tritt aus dem sich öffnenden Türfalz in den Spalt zwischen Türblatt und Türzarge ein und bewirkt hier eine zusätzliche Abdichtung und Wärmedämmung.The task is described with a door leaf of the beginning Structure according to the invention solved in that the door rebate is filled with an expanding material, which at Heating expands and bends the door rebate. Under the expanding effect of the arranged in the door rebate Inflatable material are the U-shaped angled and to In the event of a fire, the rebated edge sections are widened and pressed against the door frame surrounding the door leaf. The door leaf is so tightly clamped in the door frame that absorbs the deformation forces that occur in the event of a fire can be and the door leaf in the door frame just stands still. Part of the rapidly expanding Inflatable material emerges from the opening rebate into the Gap between door leaf and door frame and causes here an additional seal and thermal insulation.

Gemäß einer bevorzugten Ausführung der Erfindung enthält das Blähmaterial als expandierenden Wirkstoff Vermiculargraphit, der mit einem thermisch beständigen Bindemittel gebunden und verfestigt ist. Es ist als streifenförmiges Material auf einem textilen Träger erhältlich. Bei Erhitzung vergrößert sich das Volumen um ein Vielfaches, wobei ein für das Aufbiegen des aus Stahlblech gefertigten Türfalzes ausreichender Blähdruck erzeugt wird.According to a preferred embodiment of the invention contains the expanding material as an expanding active ingredient, vermicular graphite, with a thermally stable binder is bound and solidified. It's as a stripe Material available on a textile carrier. When heated the volume increases many times over, one for bending the sheet steel Sufficient expansion pressure is generated for the door rebate.

Gemäß einer bevorzugten Ausführung der Erfindung weist die kastenförmige Halbschale des Türblattes an mindestens drei Umfangsflächen nach außen abgewinkelte Randstreifen auf, an denen der Deckel aufliegt und befestigt ist. Die Befestigung erfolgt zweckmäßig durch Punktschweißen.According to a preferred embodiment of the invention, the box-shaped half-shell of the door leaf on at least three Peripheral surfaces angled to the outside on which the lid rests on and is attached. The attachment expediently carried out by spot welding.

In weiterer Ausgestaltung lehrt die Erfindung, dass an die Umfangsflächen der Halbschale ein Absatz angeformt ist, an dem das Schenkelende der U-förmig zu dem Türfalz umgebogenen Randabschnitte des Deckels aufliegt. Durch die Abstützung an dem Absatz kann der Türfalz auch bei Verwendung dünner Stahlbleche große Anschlagkräfte aufnehmen, wenn das Türblatt im Zuge einer Schließbewegung gegen die Türzarge bewegt wird. Ferner ist der Anschlussbereich zwischen Türfalz und Stahlblechkörper optisch ansprechend, da sich der Absatz und das Schenkelende des U-förmig gebogenen Türfalzes überlappen und ein Spalt nicht mehr wahrnehmbar ist. Die abgewinkelten Randstreifen der kastenförmigen Halbschale liegen im Innenbereich des Türfalzes und sind von außen nicht sichtbar. Schweißpunkte treten daher optisch nicht in Erscheinung.In a further embodiment, the invention teaches that to the A shoulder is formed on the peripheral surfaces of the half-shell which the leg end of the U-shaped bent to the door rebate Edge sections of the lid rests. By the support the door rebate on the heel can also be used thin steel sheets absorb large impact forces if that Door leaf in the course of a closing movement against the door frame is moved. Furthermore, the connection area between the door rebate and sheet steel body visually appealing, since the Heel and the leg end of the U-shaped door fold overlap and a gap is no longer perceptible. The angled edge strips of the box-shaped half-shell are inside the door rebate and are from the outside not visible. Weld spots therefore do not appear optically Appearance.
