Abstract
Description
Die vorliegende Erfindung bezieht sich auf Aufzugs-Kabinenböden in Verbundstrukturbauweise, auch Sandwich-Bauweise genannt, die in Kabinen von Personen- oder Lastenaufzügen zur Anwendung kommen. Solche Kabinen sind üblicherweise in sogenannten Kabinenrahmen eingebaut, die ihrerseits an in Liftschächten befestigten Schienen geführt und von Antriebsmaschinen über Drahtseile auf- und ab bewegt werden.The present invention relates to elevator car floors in composite structure, also sandwich construction called in cabins of passenger or Cargo lifts are used. Such cabins are Usually installed in so-called cabin frames, the in turn led to mounted in lift shafts rails and moved by drive machines via wire ropes up and down become.
Ein Aufzugs-Kabinenboden hat normalerweise die Funktion, das Gewicht des Kabinenoberbaus mit Wänden, Kabinendach, Kabinentüren und diversen Einbauten sowie auch die gesamte maximale Nutzlast aufzunehmen und, meistens über geeignete Schwingungsisolationselemente, in den Kabinenrahmen einzuleiten. Dabei ist wichtig, dass der gesamte Boden sich auch unter exzentrischer Last nicht über gewisse Grenzen deformiert, das heisst sich durchbiegt oder verdreht. Ebenso wichtig ist, dass er nicht durch Störschwingungen, wie sie hauptsächlich vom Antrieb über die Tragseile auf die Kabine übertragen werden, zu unzulässig starken Eigen-Biegeschwingungen angeregt werden kann. Dies wird am sichersten durch hohe Biege-Steifigkeit des Bodens in allen Richtungen mit daraus resultierend höchstmöglicher Biege-Eigenfrequenz erreicht. Eine weitere Anforderung an einen solchen Kabinenboden ist, dass seine Oberfläche, die meist durch ein Stahlblech gebildet wird, unter hohen, auf kleine Flächen konzentrierte Lasten (z.B. durch Transporteinrichtungen mit relativ kleinen Rädern) nicht bleibende Verformungen erleidet. Ausserdem soll ein solcher Kabinenboden eine möglichst geringe Masse sowie eine minimale Bauhöhe aufweisen. Vorschriften gewisser europäischer Länder schreiben zudem vor, dass Aufzugskabinen nur minimalste Mengen an Materialien enthalten dürfen, die nicht als "nicht brennbar" klassiert sind.An elevator cabin floor usually has the function that Weight of the cabin superstructure with walls, canopy, Cabin doors and various fittings as well as the entire maximum payload and, most of the time via suitable Vibration isolation elements, in the cabin frame initiate. It is important that the entire floor is even under eccentric load does not exceed certain limits deformed, that means bent or twisted. As well important is that he is not affected by spurious vibrations like them mainly from the drive via the suspension cables to the cab be transferred to impermissibly strong intrinsic bending vibrations can be stimulated. This will be on safest due to high bending stiffness of the soil in all Directions resulting in the highest possible bending natural frequency reached. Another request to one Such cabin floor is that its surface, mostly is formed by a steel sheet, under high, on small Areas of concentrated loads (e.g., by means of transport with relatively small wheels) non-permanent deformations suffers. In addition, should such a cabin floor a lowest possible mass and a minimum height respectively. Rules of certain European countries also stipulate that elevator cabins only minimal May contain quantities of materials that are not "not combustible "are classified.
Bekannt sind zwei grundsätzliche Konstruktionsprinzipien, von
denen das eine als Profilrahmenbauweise und das andere als
Verbundstrukturbauweise zu bezeichnen sind. Es existieren auch
Profilrahmenkonstruktionen mit auf- oder eingelegten Stahl- oder
Faserholzplatten. Die erwähnten Anforderungen werden von den
bekannten Ausführungen jedoch nur teilweise erfüllt.
EP 0 566 424 B1 beschreibt eine Ausführung eines Aufzugs-Kabinenbodens,
bei der die geforderten Eigenschaften durch
Anwendung eines Verbundstruktur-Prinzips (Sandwich-Prinzip)
erreicht werden sollen. Dabei wird im wesentlichen zwischen
einer als Verbundschicht ausgeführten oberen Deckplatte und
einer gleichartigen unteren Grundplatte ein Kern aus Holz,
Karton oder thermoplastischem Schaum eingeklebt. Um genügende
Widerstandsfestigkeit der Deckplatte, die den Kabinenbodenfläche
bildet, gegen auf kleine Flächen konzentrierte Lasten zu erreichen;
sind zwischen Streifen des Kernmaterials Stützstege
eingelegt. Damit an diesem Boden anschliessende Kabinenteile,
wie z.B. Kabinenwände oder Türschwellen fixiert werden können,
ist die beschriebene Verbundstrukturplatte von einem Stahlrahmen
umschlossen.Two basic design principles are known, one of which is to be referred to as a profile frame construction and the other as a composite structural design. There are also profile frame constructions with mounted or inserted steel or pulpwood panels. However, the mentioned requirements are only partially met by the known embodiments.
EP 0 566 424 B1 describes an embodiment of an elevator cabin floor in which the required properties are to be achieved by using a composite structure principle (sandwich principle). In this case, a core made of wood, cardboard or thermoplastic foam is glued in substantially between an upper cover plate designed as a composite layer and a similar lower base plate. In order to achieve sufficient resistance of the cover plate, which forms the cabin floor surface, against concentrated to small areas loads; are inserted between strips of the core material supporting webs. So that subsequent cabin parts, such as, for example, cabin walls or door sleepers can be fixed to this floor, the described composite structural panel is enclosed by a steel frame.
EP 0 700 860 A1 offenbart einen ebenfalls in Form einer Verbundstruktur aufgebauten Aufzugs-Kabinenboden, bei dem auf einer Basisplatte eine als Drucksensor wirkende Schicht, eine elastische Zwischenschicht und eine Fussbodenschicht aufgebaut sind. Die Basisplatte wie auch die Fussbodenschicht bilden je eine eigenständige Verbundstruktur, bestehend aus jeweils einer Kernschicht und zwei Aussenschichten. Als Kernschichten werden sogenannte Honigwabenstrukturen verwendet. Honigwabenstrukturen bestehen aus einer Vielzahl von parallel zueinander angeordneten, hochkant stehenden, dünnen Metall- oder Kunststoffstreifen, die so verformt und in definierte Abständen seitlich miteinander verklebt sind, dass sie einen Kern mit honigwabenförmigen Hohlräumen bilden. Dieser Kern ist jeweils zwischen zwei Aussenschichten eingeklebt, wobei er den Abstand zwischen diesen bestimmt und durch Übertragung von Schubspannungen zwischen den Aussenschichten die erforderliche Biegesteifigkeit der Verbundstruktur gewährleistet.EP 0 700 860 A1 also discloses one in the form of a composite structure built elevator cabin floor in which on one Base plate acting as a pressure sensor layer, an elastic Intermediate layer and a floor layer are constructed. The base plate as well as the floor layer form one each independent composite structure, consisting of one each Core layer and two outer layers. As core layers are so-called honeycomb structures used. Honeycomb structures consist of a multiplicity of mutually parallel, upright thin metal or plastic strips, the so deformed and at defined intervals laterally with each other are glued that they have a honeycomb-shaped core Form cavities. This core is in each case between two outer layers glued in, taking the distance between them determined and by transmission of shear stresses between the Outer layers the required flexural rigidity of the composite structure guaranteed.
Die Lösung gemäss EP 0 566 424 B1 wie auch diejenige nach
EP 0 700 860 A1 weisen gewisse Nachteile auf.
Wegen der Art der verwendeten Materialien und/oder wegen der
Klebeverbindungen können mit diesen Konstruktionen gewisse
Brandschutzvorschriften nicht erfüllt werden. Ausserdem können
bei Dauerbelastung Kriechvorgänge in Kernmaterial und/oder in
den Klebeverbindungen stattfinden, was zu bleibender Verformung
des Bodens mit gravierenden Folgen für die Funktionsfähigkeit
von in die Kabine integrierten Baugruppen, wie Türen, Klappen
oder Wandverkleidungselementen führen kann. Ein weiterer Nachteil
von solchen geklebten Verbundstrukturen ist, dass der
Hersteller neben den Einrichtungen zur Metallverarbeitung auch
eine Infrastruktur für einwandfreie Klebetechnik inklusive
geeignete Pressen genügender Grösse zur Verfügung haben muss.
Im Falle von Verbundstrukturen mit Honigwabenstrukturkernen sind
sogar sogar sehr komplexe Spezial-Fertigungsanlagen erforderlich.
Gegenstand der vorliegenden Erfindung ist eine Aufzugs-Kabinenboden-Konstruktion
gemäss Anspruch 1, basierend auf
der Verbundstruktur- oder Sandwich-Bauweise, die alle oben
aufgeführten Anforderungen an einen Aufzugs-Kabinenboden in
idealer Weise erfüllt.
Die Konstruktion besteht im wesentlichen aus je einer Grund-
und einer Deckplatte aus zug- und druckfestem Material mit
möglichst hohem Elastizitätsmodul, sowie einem dazwischenliegenden
Verbundstruktur-Kern, der, im Unterschied zu bisher
bekannten Ausführungen aus Holz, Schaumstoff, etc., aus einer
Art Gitterrost besteht. Dieser ist aufgebaut aus einer
Vielzahl von rechtwinklig sich kreuzenden, hochkant stehenden
Lamellen, von denen je eine Anzahl parallel zur Längs- und
zur Querkante des Bodens mit untereinander gleichen Abständen
verlaufen und die an ihren Kreuzungspunkten jeweils mit der
Grund- und der Deckplatte verbunden sind. Länge und Breite
dieses Gitterrostkerns entsprechen den Abmessungen des
Kabinenbodens. Ein nach diesem Prinzip hergestellter, mit
Hilfe von FEM-Berechnungen optimierter Kabinenboden weist,
bei gegebener Materialspezifikation und gegebenen Limiten in
bezug auf Einbauhöhe und Gewicht, optimale Steifigkeit in
allen Richtungen auf, verbunden mit einer, höchstmöglichen
Biege-Eigenfrequenz. Die entlang der quadratischen Felder des
Gitterrosts erfolgende Rundumabstützung der Deckplatte
verleiht dieser ausserdem die wichtige Fähigkeit, auf kleine
Flächen konzentrierte hohe Belastungen ohne bleibende
Verformung aufzunehmen.The solution according to EP 0 566 424 B1 as well as that according to EP 0 700 860 A1 have certain disadvantages.
Because of the nature of the materials used and / or because of the adhesive bonds, certain fire protection regulations can not be met with these constructions. In addition, under continuous load creep in nuclear material and / or in the adhesive joints can take place, which can lead to permanent deformation of the soil with serious consequences for the functionality of integrated into the cabin assemblies, such as doors, flaps or wall cladding elements. Another disadvantage of such glued composite structures is that the manufacturer must have an infrastructure for proper gluing including appropriate presses of sufficient size available in addition to the facilities for metal processing.
In the case of composite structures with honeycomb cores, even very complex special manufacturing equipment is required. The present invention is an elevator car floor construction according to claim 1, based on the composite structure or sandwich construction, which meets all the requirements listed above for an elevator car floor in an ideal manner.
The construction consists essentially of a base and a cover plate of tensile and pressure-resistant material with the highest possible modulus of elasticity, as well as an intermediate composite structure core, which, in contrast to previously known versions of wood, foam, etc., from a kind Grating exists. This is composed of a plurality of perpendicular intersecting upstanding lamellae, each of which run a number parallel to the longitudinal and the transverse edge of the floor with mutually equal distances and which are connected at their intersection points respectively with the base and the cover plate. The length and width of this grate core correspond to the dimensions of the cabin floor. A cabin floor optimized according to this principle, optimized with the aid of FEM calculations, exhibits optimum rigidity in all directions, given a given material specification and given limits in terms of installation height and weight, combined with a maximum possible bending natural frequency. The all-round support of the cover plate along the square panels of the grid also gives it the important ability to absorb high loads concentrated on small areas without permanent deformation.
Durch Ausführung der Grund- und der Deckplatte wie auch der Lamellen des Gitterrostkerns aus Stahlblech, wird einerseits die festigkeitstechnische Forderung nach einem Material mit hohem Elastizitätsmodul und minimaler Kriechneigung erfüllt, und andererseits entspricht die Konstruktion allen relevanten Brandschutzforderungen. Ein wesentlicher Vorteil ist auch, dass auf diese Weise der gesamte Boden mit konventioneller Metallverarbeitungstechnik herstellbar ist.By execution of the base and the cover plate as well as the Slats of the wire grid core made of sheet steel, on the one hand the strength-technical requirement for a material with high elastic modulus and minimum creep, and on the other hand, the construction is all relevant Fire protection requirements. A significant advantage is also that in this way the entire ground with conventional Metal processing technology can be produced.
Die erforderliche gegenseitige Verbindung der Verbundstruktur-Komponenten
erfolgt in geeigneter Weise so, dass die
Gitterrostlamellen an ihren Kreuzungspunkten mittels
"Lochschweissung" mit der Deck- und der Grundplatte, die im
folgenden als Deck- und Grundblech bezeichnet sind,
verschweisst ist. Diese Schweissung erfolgt von der
Aussenseite der beiden Bleche her durch vorgestanzte Löcher,
deren Position mit den Kreuzungspunkten der Gitterrostlamellen
übereinstimmt.
Mit dem bisher beschriebenen Verfahren wird die für eine
biegesteife Sandwichplatte entscheidende Forderung nach
starrer Schubübertragung zwischen den Grund- und Deckblechen
bei minimalem Gewicht in idealer Weise erfüllt. Bleibende
Verbiegungen oder Verdrehungen infolge von Kriechvorgängen im
Kernmaterial oder in Klebefugen unter hohen statischen Lasten
können nicht auftreten.The required mutual connection of the composite structure components is carried out in a suitable manner so that the grating louvers are welded at their intersection points by means of "hole welding" with the cover and the base plate, which are referred to below as the cover and base plate. This welding takes place from the outside of the two sheets forth by pre-punched holes whose position coincides with the crossing points of the grating louvers.
With the method described so far, the decisive requirement for a rigid sandwich panel requirement for rigid shear transfer between the base and cover plates with minimal weight in an ideal manner. Permanent bends or twists due to creep in the core material or in joints under high static loads can not occur.
Die gegenseitige mehrfache Überkreuzung der rechtwinklig zueinander verlaufenden Lamellen des Gitterrosts wird dadurch ermöglicht, dass die Lamellen an allen Kreuzungspunkten mit rechtwinklig zu ihrer Längsachse gestanzten Schlitzen versehen sind, deren Breite der Lamellen-Materialdicke entspricht, und die bei den längsverlaufenden Lamellen von oben und bei den querverlaufenden von unten jeweils bis zur halben Lamellenhöhe reichen. Dadurch lassen sich die querverlaufenden Lamellen an allen Kreuzungspunkten derart in die längsverlaufenden einstecken, dass alle Lamellen auf gleiches Niveau zu liegen kommen und den oben beschriebenen Gitterrost bilden.The mutual multiple crossover of the right angles mutually extending slats of the grating is characterized allows the slats at all crossing points with at right angles to their longitudinal axis punched slots are provided whose width of the slat material thickness corresponds, and in the longitudinal slats of above and at the transverse from below each to the reach half slat height. This can be the transverse lamellae at all points of intersection so in insert the longitudinal ones that all the slats open same level and the above described Form grid.
Die Seitenwände des Kabinenbodens sind durch Biegen des entsprechend vorgeschnittenen Deckblechs erzeugt, was den Herstellprozess vereinfacht.The side walls of the cabin floor are made by bending the according to pre-cut cover sheet produced what the Manufacturing process simplified.
Ein weiterer Vorteil der erfindungsgemässen Konstruktion besteht darin, dass die erwähnten Seitenwände des Kabinenbodens mit den Enden der Lamellen des Gitterrostkerns durch Schweissen starr verbunden sind, wodurch sich eine hoch belastbare, starre Befestigungsmöglichkeit für Bauteile wie Türschwelle, Türrahmen und Kabinenwände an diesen Seitenwänden ergibt. Another advantage of the inventive construction is that the mentioned side walls of the cabin floor with the ends of the slats of the grate core through Welding are rigidly connected, causing a high strong, rigid mounting option for components such as Threshold, door frame and cabin walls on these side walls results.
Um die gesamte Bodenkonstruktion im Tauchverfahren lackieren zu können, sind die Gitterrostlamellen an jedem Kreuzungspunkt mit gestanzten Öffnungen versehen, so dass die Lackierflüssigkeit in alle Hohlräume des Gitterrostkerns eindringen und auch wieder abfliessen kann. Dazu ist der Boden beim Tauchlackieren an einer Ecke so aufzuhängen, dass er mit etwa vertikal stehender Diagonale ins Bad eintaucht.To paint the entire floor construction in the dipping process To be able to, are the grate slats at each crossing point provided with punched openings, so that the Coating liquid in all cavities of the grate core penetrate and drain again. This is the Soak up the floor when dipping on a corner so that he dips into the bathroom with an approximately vertical diagonal.

Fig. 1 zeigt eine bevorzugte Ausführungsform des erfindungsgemässen
Aufzugs-Kabinenbodens. Der Boden ist komplett aus
Stahlblech mittels Biegen und Schweissen gefertigt. Er
besteht im wesentlichen aus dem Deckblech 1 mit angebogenem
Türschwellensupport 6, dem Grundblech 2 sowie dem zwischen
Deck- und Grundblech liegenden Gitterrostkern 3 aus sich
kreuzenden Längs- und Querlamellen 4,5. Zusätzlich sichtbar
sind Bauelemente, die aufzugsspezifische Funktionen erfüllen,
wie die Seitenwandprofile 7, Versteifungen 8 für den
Türschwellensupport sowie Tragprofile 13 mit Befestigungsgewinden
für die als Verbindung zwischen Kabinenboden und
Kabinenrahmen dienenden Isolationselemente (nicht sichtbar).
Im Bereich der Fig. 1, wo das Grundblech 2 als teilweise
entfernt dargestellt ist, erkennt man die Bauweise des
Gitterrostkerns 3. Dieser ist in Fig. 2 detaillierter
dargestellt, wo gezeigt ist, wie dank den gestanzten
Schlitzen 12 die Querlamellen 5 in die Längslamellen 4
eingefügt werden. Die Stärke der Lamellen des Gitterrostkerns
sowie deren gegenseitige Abstände sind in Abhängigkeit von
Bodenbelastung, Deckblechdicke und Gesamtbauhöhe variabel und
werden mittels FEM-Berechnungen optimiert.
Im Grundblech 2 erkennt man gestanzte, schlitzförmige Löcher
9, deren Position jeweils mit einem Kreuzungspunkt der
Lamellen des Gitterrostkerns übereinstimmt. Entsprechende
Löcher sind auch im Deckblech vorhanden. Durch diese Löcher 9
werden, wie in Fig.3 gezeigt, mittels Lochschweissung das
Deckblech 1 und das Grundblech 2 mit dem Gitterrostkern 3
starr verbunden. Grundsätzlich sind auch Durchschweissverfahren
(z.B. Laser- oder Elektronenstrahlschweissung) anwendbar,
für die keine Löcher erforderlich sind, bei deren Anwendung
jedoch die Verschweissung weniger gut beobachtet werden kann.
Aus Fig.1 ist weiter ersichtlich, dass die Enden der Lamellen
4,5 des Gitterrostkerns bis zu den Seitenwänden (z.B. bei 10)
sowie bis zu den Versteifungen des Türschwellensupports 6
reichen, wo sie mit diesen verschweisst sind und diesen
enorme Steifigkeit verleihen, was für deren Funktion als
Träger von Wänden und Türschwelle von grosser Wichtigkeit
ist.
Die Lamellen 4,5 enthalten bei jeder Kreuzungsstelle auf
ihrer halben Höhe Öffnungen 11, womit gewährleistet ist,
dass beim Tauchlackieren die Lackierflüssigkeit in alle
Hohlräume des an einer Ecke aufgehängten Kabinenbodens
eindringen und wieder abfliessen kann.Fig. 1 shows a preferred embodiment of the inventive elevator cabin floor. The floor is made entirely of sheet steel by means of bending and welding. It consists essentially of the cover plate 1 with gebogenem door sill support 6, the
