AUFZUGTUR MIT DAMMSTOFFPLATTEELEVATOR DOOR WITH INSULATION PANEL
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 AI 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 Führungs- elemente, über die die Aufzugstür entlang Führungen der Aufzugskabine verfahrbar ist, sind üblicherweise im Bereich des Seitenkanten des Türblattes befestigt.Such an elevator door, known for example from DE 44 20 646 A1, is manufactured, for example, from folded steel sheets, the door being manufactured with one or two shells. 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 Ausstei- fungselemente für die gekanteten Stahlbleche der Auf- zugtür 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.Solutions of this type have the disadvantage that, on the one hand, considerable effort is required to manufacture and assemble the stiffening elements for the folded steel sheets of the lift door and the stiffening elements. Furthermore, the elevator doors have a considerable weight, particularly in the case of the double-shell construction with a box profile made of folded steel sheets, 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, with conventional elevator doors there are always problems with 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 is easy to manufacture and is lightweight, good mechanical stability as well as good sound and temperature insulation and heat stability.
Diese Aufgabe wird durch eine Aufzugtür mit den Merk- malen 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, the visible surface of the elevator door being formed by a load-bearing cover plate, which is provided on the back 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 insulation board is made as a high-temperature-resistant foam board, preferably from high-temperature-resistant inorganic foam, so that the fire protection behavior is significantly improved compared to conventional solutions.
Durch den Schichtaufbau mit einer Deckplatte und ei- ner darauf aufgebrachten Dämmstoffplatte wird eine Auf- zugtür 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 plate attached to it, an elevator door with a high degree of rigidity is created, so that a high degree of dimensional stability of the door is guaranteed even with high thermal loads. Since the cover plate can be produced in a simple manner by folding and the function of the stiffening is achieved by the insulation board, the manufacturing costs are significantly lower compared to a solution with a box profile.
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, in particular in the event of a fire, can be easily adapted to the requirements by increasing or decreasing the thickness of the insulation panel, without the door having to be redesigned.
Um die Aussteifungsfunktion durch die Dämmstoffplatte zu erreichen, ist diese vorzugsweise durch Kleben oder direkt durch Ausschäumen auf die Deckplatte aufzubringen. 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.In order to achieve the stiffening function through the insulation board, this should preferably be applied to the cover board by gluing or directly by foaming. The fire protection behavior of the elevator door can be further improved if, in addition to gluing or foaming, the insulating material is connected to the cover plate by mechanical connecting means. In this way, a reliable hold of the insulating material is ensured even if the adhesive connection is broken due to overheating.
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 steel sheet, the side edges of the cover plate being bent at least in sections in such a way that a receiving space for the insulation plate is created.
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 bent in an L-shaped manner, so that the peripheral edge of the cover plate extends approximately in parallel to the large rear surface of the insulating plate. The guide elements of the elevator door can be attached to the side edges created by the folds.
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 made of inorganic rigid foam, this material can also be used to glue the insulation board to the cover plate, so that due to the uniformity of material, good adhesion to the cover plate is ensured even at high temperatures.
Sonstige vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der weiteren Unteransprüche.Other advantageous developments of the invention are the subject of the further subclaims.
Im folgenden wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand schematischer Zeichnungen näher erläutert. Es zeigen: Figur 1 eine Draufsicht auf eine erfindungsgemäße Aufzugtür und;A preferred embodiment of the invention is explained in more detail below with the aid of schematic drawings. Show it: Figure 1 is a plan view of an elevator door and;
Figur 2 ein Schnitt entlang der Linie A-A in Figur 1.Figure 2 is a section along the line A-A 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 top view of an elevator door 1 according to the invention from the visible surface, i.e. from the inside of the elevator car. Accordingly, the elevator door 1 has a cover plate 2 which forms the visible surface and is made of sheet steel or aluminum, on the rear side of which is visible in FIG. 2, an insulation plate 4 is fastened. The cover plate 2 is produced by folding or deep drawing, the peripheral edges being folded at least in the region of the narrow sides 6, 8 in such a way that there is a rear receiving space for the insulation plate 4.
Bei dem in den Figuren 1 und 2 dargestellten Ausfüh- rungsbeispiel einer Aufzugtür 1 wurde die oben liegende Umfangskante 8 L-förmig abgekantet, so daß der schmalsei- tige 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 exemplary embodiment of an elevator door 1 shown in FIGS. 1 and 2, the upper peripheral edge 8 was bent in an L-shape, so that the narrow-sided peripheral edge is formed by a leg 10 which runs approximately parallel to the visible surface. As indicated in FIG. 1, guide elements 12, for example guide rollers, can be fastened to this leg 10 of the upper peripheral edge 8, via which the elevator door 1 is guided in a corresponding guide of the elevator car or shaft door guide.
An der untenliegenden Umfangskante 6 sind lediglich zwei Teilbereich L-förmig abgekantet, so daß sich zwei laschenförmige Vorsprünge 14 ergeben, an denen ebenfalls Führungselemente befestigbar sind.On the underlying peripheral edge 6, only two partial areas are bent in an L-shape, so that two tab-shaped projections 14 result, to which guide elements can also be fastened.
Je nach Anwendungsfall können auch die längsseitigen Umfangskanten 16, 18 umgekantet sein, so daß die Dämm- platte 4 entlang ihres Außenumfangs von der Deckplatte 2 umgriffen ist. 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.Depending on the application, the longitudinal peripheral edges 16, 18 can also be folded over, so that the insulating plate 4 is encompassed by the cover plate 2 along its outer circumference. According to the invention, it is preferred if the insulation board 4 is produced as a foam board, preferably from inorganic foam, since such materials have excellent temperature resistance. The rigid foam can be open or closed cell, the density 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 attached to the cover plate 2 by gluing. However, it is also conceivable to foam the foam directly onto the cover plate.
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 Spaltpro- dukte freigesetzt werden. Des weiteren ist durch dieThe same material as is used in the production of the foam is preferably used as the adhesive. This uniformity of materials ensures that no toxic fission products are released in the event of a fire. Furthermore, through the
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.Uniformity of materials ensures that the insulating material is recycled so that no hazardous waste is generated. Inorganic insulating foams are further characterized by an optimal sound insulation and insulating effect, so that it is ensured that the desired conditions (climate, noise level, etc.) when opening and closing the door and inside the elevator car can be set.
Für den Fall, daß der Klebstoff bei einer extremenIn the event that the adhesive at an extreme
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 Sollposi- tion gehalten wird, so daß im Brandfall eine hinreichende Wärmedämmung gewährleistet ist und ein Herausfallen der Fämmplatte 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 Aufzug- schacht keine Brandbrücke darstellt, daß sich die Aufzug- kabine nicht mehr öffnen läßt. Die Verbindungsmittel 20 können entlang des Umfangs der Dämmplatte 4 oder sie überspannend angeordnet werden.If the temperature increase is softened or released, the mechanical connecting means 20 indicated in FIGS. 1 and 2 can also be used. Such mechanical connecting means 20 can be clamping brackets, springs or the like, with which the insulation board 4, even when the adhesive is loosened, in its desired position. tion is kept so that in the event of fire adequate thermal insulation is ensured and falling out of the insulation board is avoided. Thermal insulation is particularly important with regard to the dimensional stability of the door, since warping of the door when exposed to high temperatures must be avoided so that the elevator shaft does not constitute a fire bridge and the elevator car can no longer be opened. The connecting means 20 can be arranged along the circumference of the insulation board 4 or spanning it.
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 requirements, the large rear surface of the insulation board 4 can still be covered with decorative material. However, this decorative material then only serves to improve the visual appearance in the case of glazed manholes. The stability is essentially ensured by the composite system of cover plate 2 and insulation plate 4.
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 die durch 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 Fertigungs- spuren 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 very simple, since only the cover plate 2 has to be cut and deep-drawn and / or folded in a first work step and then the insulation plate 4 has to be additionally fixed in place by gluing by mechanical connecting elements 20. Since practically no additional reinforcement elements, such as aluminum profiles, etc., have to be applied to the rear of the cover plate 2, there are no signs of processing or manufacturing marks on the visible surface. This makes it possible to finish painting the cover plate 2 before the insulation plate 4 is stuck on, so that practically no reworking is required.
Offenbart ist ein Aufzugtür, bei der auf eine gekan- tete 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. What is disclosed is an elevator door in which an insulating plate, preferably made of inorganic foam, is not only used as an insulating plate on an edged or deep-drawn cover plate 2 Insulation material, but applied to increase the rigidity, and is preferably firmly glued or foamed.
