Abstract
Description
Die Erfindung betrifft eine Aufzugtür gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an elevator door according to the preamble of patent claim 1.
Eine derartige, beispielsweise aus der DE 44 20 646 A1 bekannte Aufzugtür wird beispielsweise aus gekanteten Stahlblechen gefertigt, wobei die Tür einschalig oder in Kastenbauweise zweischalig hergestellt wird. Zur Erhöhung der Steifigkeit der Stahlbleche werden Blechprofile auf der Rückseite der Aufzugstüren aufgebracht. Die Führungselemente, über die die Aufzugstür entlang Führungen der Aufzugskabine verfahrbar ist, sind üblicherweise im Bereich des Seitenkanten des Türblattes befestigt.Such, for example, from DE 44 20 646 A1 known elevator door is made for example of folded steel sheets, the door is single-shell or box-shaped double-shelled. To increase the rigidity of the steel sheets sheet metal profiles are applied to the back of the elevator doors. The guide elements, via which the elevator door can be moved along guides of the elevator car, are usually fastened in the region of the side edges of the door leaf.
Derartige Lösungen haben den Nachteil, daß zum einen ein erheblicher Aufwand erforderlich ist, um die Aussteifungselemente für die gekanteten Stahlbleche der Aufzugtür und die Aussteifungselemente herzustellen und diese zu montieren. Des weiteren haben insbesondere bei der zweischaligen Bauweise mit einem Kastenprofil aus gekanteten Stahlblechen die Aufzugtüren ein erhebliches Gewicht, so daß der Antrieb zum Schließen und Öffnen der Tür entsprechend ausgelegt werden muß.Such solutions have the disadvantage that on the one hand a considerable effort is required to produce the stiffening elements for the folded steel sheets of the elevator door and the stiffening elements and to assemble them. Furthermore, especially in the two-shell construction with a box section of folded steel sheets, the elevator doors have a considerable weight, so that the drive for closing and opening the door must be designed accordingly.
Außerdem treten bei herkömmlichen Aufzugstüren immer wieder Probleme hinsichtlich der Schallabstrahlung beim Auf- oder Zulaufen sowie Schließen der Türen auf.In addition, occur in conventional elevator doors repeatedly problems with regard to the sound radiation when opening or closing and closing the doors.
Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Aufzugtür zu schaffen, die auf einfache Weise herstellbar ist und sich durch ein geringes Gewicht, gute mechanische Stabilität sowie gute Schall- und Temperaturdämmung und Hitzestabilität auszeichnet.In contrast, the invention has for its object to provide an elevator door that can be produced in a simple manner and by a low weight, good mechanical stability and good sound and temperature insulation and heat stability distinguishes.
Diese Aufgabe wird durch eine Aufzugtür mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by an elevator door with the features of patent claim 1.
Erfindungsgemäß hat die Aufzugtür einen Schichtaufbau, wobei die Sichtfläche der Aufzugtür durch eine tragende Deckplatte gebildet ist, die rückseitig mit einer Dämmstoffplatte versehen ist. Diese Dämmstoffplatte dient einerseits zur Versteifung der Aufzugstür und andererseits zur Verbesserung der Wärme- und Schalldämmung. Besonders bevorzugt wird es, wenn die Dämmplatte als hochtemperaturfeste Schaumstoffplatte, vorzugsweise aus hochtemperaturfestem anorganischem Schaumstoff hergestellt ist, so daß das Brandschutzverhalten gegenüber herkömmlichen Lösungen wesentlich verbessert ist.According to the invention, the elevator door has a layer structure, wherein the visible surface of the elevator door is formed by a load-bearing cover plate, which is provided on the rear side with an insulating material plate. This insulation board serves on the one hand to stiffen the elevator door and on the other hand to improve the heat and sound insulation. It is particularly preferred if the insulating board is made as a high temperature resistant foam board, preferably made of high temperature resistant inorganic foam, so that the fire protection performance compared to conventional solutions is substantially improved.
Durch den Schichtaufbau mit einer Deckplatte und einer darauf aufgebrachten Dämmstoffplatte wird eine Aufzugtür mit einer hohen Steifigkeit geschaffen, so daß eine hohe Formstabilität der Tür auch bei hohen thermischen Belastungen gewährleistet ist. Da die Deckplatte auf einfache Weise durch Abkanten hergestellt werden kann und die Funktion der Aussteifung durch die Dämmstoffplatte erreicht wird, sind die Fertigungskosten gegenüber einer Lösung mit Kastenprofil wesentlich geringer.Due to the layer structure with a cover plate and an insulation panel applied thereon, an elevator door with a high rigidity is created, so that a high dimensional stability of the door is ensured even at high thermal loads. Since the cover plate can be easily produced by folding and the function of the stiffening is achieved by the insulation board, the manufacturing cost compared to a solution with box section are much lower.
Das Dämmverhalten insbesondere im Brandfall läßt sich auf einfache Weise durch Vergrößern oder Verringern der Stärke der Dämmplatte an die Anforderungen anpassen, ohne daß es einer Umkonstruktion der Tür bedarf.The insulation behavior especially in case of fire can be easily adapted by increasing or decreasing the thickness of the insulation board to the requirements, without the need for a redesign of the door.
Um die Aussteifungsfunktion durch die Dämmstoffplatte zu erreichen, ist diese vorzugsweise durch Kleben oder direkt durch Ausschäumen auf die Deckplatte aufzubringen.In order to achieve the stiffening function by the insulation board, this is preferably applied by gluing or directly by foaming on the cover plate.
Das Brandschutzverhalten der Aufzugtür läßt sich weiter verbessern, wenn zusätzlich zu einem Aufkleben oder Aufschäumen des Dämmaterials, dieses über mechanische Verbindungsmittel mit der Deckplatte verbunden wird. Auf diese Weise ist ein zuverlässiges Halten des Dämmaterials auch bei einem durch Überhitzung verursachtes Auflösen der Klebeverbindung gewährleistet.The fire protection performance of the elevator door can be further improved if, in addition to gluing or foaming of the insulating material, this is connected via mechanical connection means with the cover plate. In this way, a reliable holding of the insulating material is ensured even when caused by overheating dissolving the adhesive bond.
Erfindungsgemäß wird es bevorzugt, wenn die Deckplatte als gekantetes Stahlblech hergestellt wird, wobei die Seitenkanten der Deckplatte zumindest abschnittsweise derart aufgebogen werden, daß ein Aufnahmeraum für die Dämmplatte geschaffen wird.According to the invention, it is preferred if the cover plate is produced as a folded sheet steel, wherein the side edges of the cover plate are bent at least in sections such that a receiving space for the insulation board is provided.
Bei einer besonders bevorzugten Variante werden die Umfangskanten L-förmig abgekantet, so daß der Umfangsrand der Deckplatte etwa in Parallelrichtung zur rückwärtigen Großfläche der Dämmplatte verläuft. An den durch die Abkantungen geschaffenen Seitenkanten können die Führungselemente der Aufzugtür befestigt werden.In a particularly preferred variant, the peripheral edges are L-shaped folded so that the peripheral edge of the cover plate extends approximately in the direction parallel to the rear large surface of the insulation board. At the side edges created by the folds, the guide elements of the elevator door can be fastened.
Für den Fall, daß die Dämmplatte aus anorganischem Hartschaumstoff ausgebildet ist, kann dieses Material auch zum Verkleben der Dämmplatte mit der Deckplatte verwendet werden, so daß aufgrund der Materialeinheitlichkeit auch bei hohen Temperaturen ein gutes Anhaften an der Deckplatte gewährleistet ist.In the event that the insulation board is formed of inorganic rigid foam, this material can also be used for bonding the insulation board with the cover plate, so that due to the uniformity of materials, even at high temperatures a good adhesion to the cover plate is guaranteed.
Sonstige vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der weiteren Unteransprüche.Other advantageous developments of the invention are the subject of the other dependent claims.
Im folgenden wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand schematischer Zeichnungen näher erläutert. Es zeigen:
- Figur 1 eine Draufsicht auf eine erfindungsgemäße Aufzugtür und;
Figur 2 ein Schnitt entlang der Linie A-A in Figur 1.
- Figure 1 is a plan view of an elevator door according to the invention and;
- 2 shows a section along the line AA in Figure 1.
Figur 1 zeigt eine Draufsicht auf eine erfindungsgemäße Aufzugtür 1 von der Sichtfläche, d.h. von der Innenseite der Aufzugkabine, her. Demgemäß hat die Aufzugtür 1 eine die Sichtfläche ausbildende Deckplatte 2 aus Stahl- oder Aluminiumblech, auf deren in Figur 2 sichtbare Rückseite eine Dämmplatte 4 befestigt ist. Die Herstellung der Deckplatte 2 erfolgt durch Abkanten oder Tiefziehen, wobei die Umfangskanten zumindest im Bereich der Schmalseiten 6, 8 derart gekantet sind, daß sich ein rückwärtiger Aufnahmeraum für die Dämmplatte 4 ergibt.Figure 1 shows a plan view of an elevator door 1 according to the invention from the viewing surface, i. from the inside of the elevator car, forth. Accordingly, the elevator door 1 has a
Bei dem in den Figuren 1 und 2 dargestellten Ausführungsbeispiel einer Aufzugtür 1 wurde die oben liegende Umfangskante 8 L-förmig abgekantet, so daß der schmalseitige Umfangsrand durch einen Schenkel 10 gebildet ist, der etwa parallel zur Sichtfläche verläuft. Wie in Figur 1 angedeutet, können an diesen Schenkel 10 der oben liegenden Umfangskante 8 Führungselemente 12, beispielsweise Führungsrollen befestigt werden, über die die Aufzugtür 1 in einer entsprechenden Führung der Aufzugkabine oder Schachttürführung geführt ist.In the embodiment of an elevator door 1 shown in Figures 1 and 2, the overhead
An der untenliegenden Umfangskante 6 sind lediglich zwei Teilbereiche L-förmig abgekantet, so daß sich zwei laschenförmige Vorsprünge 14 ergeben, an denen ebenfalls Führungselemente befestigbar sind.At the lower
Je nach Anwendungsfall können auch die längsseitigen Umfangskanten 16, 18 umgekantet sein, so daß die Dämmplatte 4 entlang ihres Außenumfangs von der Deckplatte 2 umgriffen ist.Depending on the application, the longitudinal
Erfindungsgemäß wird es bevorzugt, wenn die Dämmplatte 4 als Schaumstoffplatte, vorzugsweise aus anorganischem Schaumstoff hergestellt ist, da derartige Materialien eine exzellente Temperaturbeständigkeit aufweisen. Der Hartschaumstoff kann offen- oder geschlossenzellig ausgeführt werden, wobei das Raumgewicht vorzugsweise zwischen 100 und 800 kg/m3 liegt. Eine optimale Porengröße dürfte zwischen 0,5 bis 3 mm angeordnet sein.According to the invention it is preferred if the insulating panel 4 is made as a foam plate, preferably made of inorganic foam, since such materials have excellent temperature resistance. The rigid foam can be made open or closed cell, wherein the density is preferably between 100 and 800 kg / m 3 . An optimal pore size should be between 0.5 to 3 mm.
Bei dem dargestellten Ausführungsbeispiel ist die Dämmplatte 4 durch Kleben an der Deckplatte 2 befestigt. Vorstellbar ist jedoch auch, den Schaumstoff direkt auf die Deckplatte aufzuschäumen.In the illustrated embodiment, the insulation board 4 is fixed by gluing to the
Als Klebstoff wird vorzugsweise das gleiche Material verwendet, wie es bei der Herstellung des Schaumstoffs eingesetzt ist. Durch diese Materialeinheitlichkeit ist gewährleistet, daß im Brandfall keine toxischen Spaltprodukte freigesetzt werden. Des weiteren ist durch die Materialeinheitlichkeit ein Recycling des Dämmaterials gewährleistet, so daß kein Sondermüll anfällt. Anorganische Isolierschaumstoffe zeichnen sich des weiteren durch eine optimale Schalldämmung und Isolationswirkung aus, so daß gewährleistet ist, daß die beim Öffnen und Schließen der Türe sowie im Inneren der Aufzugskabine gewünschten Bedingungen (Klima, Lärmpegel etc.) eingestellt werden können.The adhesive used is preferably the same material as used in the production of the foam. This material uniformity ensures that in case of fire no toxic cleavage products are released. Furthermore, a recycling of the insulating material is ensured by the uniformity of materials, so that no special waste is obtained. Inorganic insulating foams are further characterized by an optimal sound insulation and insulation effect, so that it is ensured that the desired opening and closing of the door and in the interior of the elevator car conditions (climate, noise level, etc.) can be adjusted.
Für den Fall, daß der Klebstoff bei einer extremen Temperaturerhöhung aufgeweicht oder gelöst wird, können zusätzlich die in den Figuren 1 und 2 angedeuteten mechanischen Verbindungsmittel 20 verwendet werden. Derartige mechanische Verbindungsmittel 20 können Klemmbügel, Federn oder ähnliches sein, mit denen die Dämmplatte 4 auch bei einem Lösen des Klebstoffes in ihrer Sollposition gehalten wird, so daß im Brandfall eine hinreichende Wärmedämmung gewährleistet ist und ein Herausfallen der Dämmplatte vermieden wird. Die Wärmedämmung ist insbesondere im Hinblick auf die Formstabilität der Tür wichtig, da ein Verziehen der Tür beim Einwirken von hohen Temperaturen zu vermeiden ist, damit der Aufzugschacht keine Brandbrücke darstellt, daß sich die Aufzugkabine nicht mehr öffnen läßt. Die Verbindungsmittel 20 können entlang des Umfangs der Dämmplatte 4 oder sie überspannend angeordnet werden.In the event that the adhesive is softened or loosened during an extreme temperature increase, the mechanical connection means 20 indicated in FIGS. 1 and 2 can additionally be used. Such mechanical connection means 20 may be clamps, springs or the like, with which the insulation board 4 even with a release of the adhesive in its desired position is kept, so that in case of fire sufficient thermal insulation is ensured and falling out of the insulation board is avoided. The thermal insulation is particularly important in view of the dimensional stability of the door, as warping of the door when exposed to high temperatures is to be avoided, so that the elevator shaft is not a fire bridge, that the elevator car can not be opened. The connecting means 20 can be arranged spanning along the circumference of the insulating panel 4 or.
Um hohen ästhetischen Ansprüchen zu genügen, kann die rückwärtige Großfläche der Dämmplatte 4 noch mit Dekormaterial belegt werden. Dieses Dekormaterial dient dann allerdings lediglich zur Verbesserung der optischen Anmutung bei verglasten Schächten. Die Stabilität wird im wesentlichen durch das Verbundsystem Deckplatte 2 und Dämmplatte 4 gewährleistet.In order to meet high aesthetic standards, the rear large area of the insulation panel 4 can still be covered with decorative material. However, this decorative material then only serves to improve the visual appearance of glazed shafts. The stability is ensured essentially by the composite
Die Produktion der erfindunsgemäßen Aufzugtür 1 ist denkbar einfach, da lediglich die Deckplatte 2 in einem ersten Arbeitsgang zugeschnitten und tiefgezogen und/oder abgekantet werden muß und anschließend die Dämmplatte 4 durch Verkleben, ggfs. zusätzlich durch die mechanischen Verbindungselemente 20 lagefixiert werden muß. Da an der Rückseite der Deckplatte 2 praktisch keinerlei zusätzliche Verstärkungselemente, wie beispielsweise Aluminiumprofile etc. aufgebracht werden müssen, zeichnen sich an der Sichtfläche keinerlei Bearbeitungs- oder Fertigungsspuren ab. Dies ermöglicht es, die Deckplatte 2 bereits vor dem Aufkleben der Dämmplatte 4 fertig zu lackieren, so daß praktisch keine Nachbearbeitung erforderlich ist.The production of the elevator door 1 according to the invention is conceivably simple, since only the
Offenbart ist ein Aufzugtür, bei der auf eine gekantete oder tiefgezogene Deckplatte 2 eine Dämmplatte, vorzugsweise aus anorganischem Schaumstoff nicht nur als Dämmaterial, sondern zur Erhöhung der Steifigkeit aufgebracht, und zwar vorzugsweise fest verklebt oder aufgeschäumt ist.Disclosed is an elevator door, in which a canted or deep-drawn
