Abstract

The shaft door has at least one door panel (10) with a sheet bowl on the outward-facing side containing a thermal insulation filling. On the shaft side, the door panel has a cover (12) in which there is at least one through aperture (16). The cover is of softer material than the sheet bowl, so that thermal deformation of the door panel depends on the temperature ratio of the outward-facing sheet bowl.

Description

Die vorliegende Erfindung betrifft eine brandsichere Schachttür, insbesondere Schachtschiebetür, für Aufzüge.The present invention relates to a fireproof shaft door, in particular shaft sliding door, for elevators.

Brandschutztüren für Aufzüge und Aufzugsanlagen sind bekannt. Aus der FR 2 131 071 ist bekannt, eine Brandschutztür für einen Aufzug aus einer normalen Schachttür und einer speziellen Brandschutztür aufzubauen. Die beiden einander zugeordneten Türen sind parallel zueinander verschiebbar hintereinander in die Schachtöffnung eingebaut, wobei im normalen Betriebszustand nur die eigentliche Schachttür geöffnet und geschlossen wird. Die zweite, brandsicher ausgestaltete Tür bleibt während des normalen Betriebs stets geöffnet und wird nur im Brandfall geschlossen. Diese bekannte Lösung, die auch aus der EP 0 572 744 A1 bekannt ist, ist jedoch bauraum- und kostenintensiv.Fire doors for elevators and elevator systems are known. From FR 2 131 071 it is known to build a fire door for an elevator from a normal landing door and a special fire door. The two mutually associated doors are mounted parallel to each other displaceable in succession in the shaft opening, wherein in the normal operating state, only the actual shaft door is opened and closed. The second, fireproof door remains open during normal operation and is only closed in case of fire. However, this known solution, which is also known from EP 0 572 744 A1, is space-consuming and cost-intensive.

Aus der EP 0 479 238 B1 ist eine brandsichere Schachttür für einen Aufzug bekannt, die für sich allein genommen die notwendige Brandsicherheit aufweist, so daß keine zweite, im Brandfall zu schließende Tür vorgesehen sein muß. Die bekannte Brandschutztür für einen Aufzug ist jedoch sehr aufwendig aufgebaut, da sie aus einem doppelschaligen Türblatt mit einer weiteren Blechschale als Vorsatzschale ausgestattet ist. Die einzelnen Blechschalen bzw. -platten sind mit aufwendigen und versetzt zueinander angeordneten Stützkonstruktionen miteinander verbunden und befestigt, wobei die dadurch zwischen den einzelnen Blechteilen entstehenden Zwischenräume mit Wärmeisoliermaterial gefüllt sind.From EP 0 479 238 B1 a fireproof shaft door for a lift is known, which in itself has the necessary fire safety, so that no second, to be closed in case of fire door must be provided. However, the known fire door for an elevator is very expensive, since it is equipped with a double-shell door leaf with another sheet metal shell as an attachment shell. The individual sheet metal shells or plates are connected to each other with elaborate and mutually offset support structures and fixed, wherein the resulting between the individual sheet metal parts spaces are filled with heat insulating material.

Demgegenüber wird erfindungsgemäß eine Schachttür für einen Aufzug vorgeschlagen, die mindestens ein Türblatt mit einer stockwerkseitig angeordneten Blechschale aufweist, in der mindestens eine Füllung aus einem Wärmedämmaterial angeordnet ist. Schachtseitig weist das Türblatt zur Halterung des Wärmedämmaterials eine mit mindestens einem Durchbruch versehene Abdeckung auf. Bei dieser Abdeckung handelt es sich vorteilhafterweise um eine zweite Blechschale zur Vervollständigung des Türblatts, in deren Fläche vorzugsweise eine Mehrzahl von Durchbrüchen vorgesehen sind. In anderer Ausgestaltung der Erfindung handelt es sich bei der Abdeckung um eine maschen- oder siebartig ausgestaltete Struktur wie beispielsweise ein Drahtgitter. In noch anderer Ausgestaltung der Erfindung besteht die Abdeckung aus einigen horizontalen Blechstreifen.In contrast, a landing door for a lift is proposed according to the invention, which has at least one door leaf with a storey-mounted sheet metal shell, in which at least one filling is arranged from a thermal insulating material. Shaft side, the door leaf for holding the thermal insulation material provided with at least one opening cover. This cover is advantageously a second sheet metal shell for completing the door leaf, in whose surface preferably a plurality of openings are provided. In another embodiment of the invention, the cover is a mesh or sieve-like configured structure such as a wire mesh. In still another embodiment of the invention, the cover consists of several horizontal metal strips.

Bei Versuchen hat sich erwiesen, daß die zwei beabstandet zueinander angeordneten Türaußenbleche eines herkömmlichen doppelschaligen Türblatts sich im Brandfall unterschiedlich aufheizen und aufgrund des sogenannten Bimetall-Effekts eine ungleichmäßige Verbiegung bzw. Krümmung auftritt, so daß die unteren Führungsteile der Schachttür aus den Führungsschlitzen der Schwelle herausgezogen werden und die Tür somit in ihrem unteren Bereich nicht mehr gestützt und geführt ist. Dies erhöht die Unfallgefahr und eröffnet den Flammen den Weg in den Schacht. Durch die erfindungsgemäße Ausgestaltung der schachtseitigen Abdeckung des doppelschaligen Türblatts mit Durchbrüchen wird die dem Schacht zugewandte Türblechfläche "weicher" und kann von der sich unter Flammen- und Hitzeeinfluß ausdehnenden stockwerkseitigen Blechschale etwas auseinander gezogen werden, so daß das Türblatt insgesamt gerade bleibt. Mit anderen Worten: Ein temperaturbedingtes Verformen des Türblattes wird im wesentlichen durch das Temperaturverhalten der stockwerkseitigen Blechschale bestimmt.In experiments, it has been found that the two spaced apart door outer panels of a conventional double-shell door panel heat up differently in case of fire and due to the so-called bimetallic effect uneven bending or curvature occurs, so that the lower guide parts of the shaft door pulled out of the guide slots of the threshold and thus the door is no longer supported and guided in its lower area. This increases the risk of accidents and opens the way for the flames into the shaft. Due to the inventive design of the shaft-side cover of the double-shell door leaf with openings, the shaft facing the door panel surface is "softer" and can from the below Flame and heat influence expanding floor-side sheet metal shell slightly pulled apart, so that the door leaf remains straight overall. In other words: A temperature-induced deformation of the door leaf is essentially determined by the temperature behavior of the storey-side sheet metal shell.

Die Durchbrüche der schachtseitigen Abdeckung können im Falle einer Blechschale beliebig ausgestaltete Schlitze sein, wobei die Anbringung von langen horizontalen Schlitzen bevorzugt wird. Selbstverständlich ist auch eine Ausgestaltung mit vertikalen Schlitzen möglich. Ferner können die Durchbrüche als T-förmige oder H-förmige Schlitze ausgebildet sein. Eine weitere Möglichkeit besteht in der Ausgestaltung des schachtseitigen Türblechs als Lochblende bzw. Lochblech mit einer Vielzahl von Löchern. Wesentlich bei allen in den Bereich der Erfindung fallenden Ausführungen der Durchbrüche ist, daß die schachtseitige Abdeckung das in der stockwerkseitigen Blechschale angeordnete Wärmedämmaterial vor dem Herausfallen aus dem Türblatt sichert.The openings of the shaft-side cover may be in the case of a sheet metal shell arbitrarily configured slots, the attachment of long horizontal slots is preferred. Of course, an embodiment with vertical slots is possible. Furthermore, the openings may be formed as T-shaped or H-shaped slots. Another possibility is the design of the shaft-side door panel as a perforated plate or perforated plate with a plurality of holes. It is essential in all embodiments of the breakthroughs falling within the scope of the invention that the shaft-side cover secures the heat-insulating material arranged in the storey-side sheet metal shell from falling out of the door leaf.

Insbesondere können die Schlitze bzw. Durchbrüche breiter sein als die verbleibenden Restbereiche der Abdeckung.In particular, the slots or openings may be wider than the remaining areas of the cover.

Die schachtseitige Abdeckung ist vorteilhafterweise mit der stockwerkseitigen Blechschale des Türblatts nur im Bereich des Türblattrandes verbunden, beispielsweise durch Verschweißung oder andere bekannte Blechverbindungsarten.The shaft-side cover is advantageously connected to the floor-side sheet metal shell of the door leaf only in the region of the door leaf edge, for example by welding or other known Blechverbindungsarten.

Die Türblattbefestigung bzw. -aufhängung ist vorteilhafterweise nur an der stockwerkseitigen Blechschale des Türblatts angeordnet.The door leaf attachment or suspension is advantageously arranged only on the storey-side sheet metal shell of the door leaf.

In anderer Ausgestaltung der Erfindung ist die Türblattaufhängung und -führung an der Verbindung zwischen der stockwerkseitigen Blechschale und der schachtseitigen Abdeckung angeordnet. Selbstverständlich kann die Türblattaufhängung und -führung auch an der stockwerkseitigen Blechschale sowie der schachtseitigen Abdeckung angeordnet sein.In another embodiment of the invention, the door leaf suspension and guide is arranged at the connection between the storey-side sheet metal shell and the shaft-side cover. Of course, the door leaf suspension and guide can also be arranged on the storey-side sheet metal shell and the shaft-side cover.

Das Wärmedämmaterial besteht vorteilhafterweise aus Platten, insbesondere mit dem Hauptbestandteil Gips. Ebenso können auch andere Arten von Dämmaterial eingesetzt werden.The thermal insulation material is advantageously made of plates, in particular with the main component gypsum. Likewise, other types of insulating material can be used.

Weitere Vorteile und Ausgestaltungen der Erfindung sind in den sich anschließenden Unteransprüchen beschrieben und ergeben sich aus der Beschreibung und der beiliegenden Zeichnung.Further advantages and embodiments of the invention are described in the subsequent subclaims and emerge from the description and the accompanying drawings.
