Definitions
- the present invention relates to an escalator or a moving walkway with at least one supporting structure, which is supported between the supports on a cable, which is arranged laterally as an auxiliary structure or under the supporting structure.
- the cable is also referred to as undervoltage.
- a supporting structure is present on both sides of the escalator or moving walk.
- Such an escalator or a moving walk is from the EP866019 A1 known. Due to the undervoltage, the structure can bridge longer spans, or it can be dimensioned smaller at the same span, so that the escalator or the moving walkway looks slimmer.
- the moving walk connects a first floor with a second floor. He lies on supports (not shown) on the respective floor slabs 10 and 11 respectively.
- the sidewalk is laterally bounded by balustrades 12, 13, for example made of glass, which carry a handrail 14, 15 at the top.
- a lever 2 is mounted at each point 1, namely at the lower flange 6 or in its vicinity.
- This lever 2 is supported by a sliding bearing 17, which may be formed as a damping plate, on the respective floor slab 10 and 11 from.
- a cable 3 attached, which is connected to the supporting points 4 with the structure 16. This cable 3 serves as undervoltage.
- the present invention works as follows: when the moving walk is heavily loaded, the structure 16 begins to deflect. This bending counteracts the cable 3, on which the supporting structure 16 is supported at the support points 4. The cable 3 is thereby additionally burdened, so that it stretches a bit. As a result of the deflection of the structure 16, the lower flange 6 expands and the upper flange 5 shortens. The points 1 lying on the lower flange 6 therefore move slightly apart, that is to say towards the adjacent floor slab 10 or 11 respectively. The lower ends of the levers 2 thereby slide slightly downward in the plain bearings 17, and the two levers 2 rotate so that their upper ends move more towards the respective floor slab 10 and 11, respectively, than the points 1. Thus, the cable 3, which then causes an additional Unterstützugkraft ⁇ Fu in the support points.
- a total of four such levers 2 are present, two on each side of the moving walk at the top and at the bottom.
- the construction can be done by diagonal braces 18 (see Fig. 2 ) are laterally stabilized.

Description
Die vorliegende Erfindung betrifft eine Fahrtreppe oder einen Fahrsteig mit mindestens einem Tragwerk, das sich zwischen den Auflagern an einem Kabel abstützt, welches als Hilftragwerk seitlich bzw. unter dem Tragwerk angeordnet ist. Das Kabel wird auch als Unterspannung bezeichnet. Üblicherweise ist zu beiden Seiten der Fahrtreppe bzw. des Fahrsteiges ein Tragwerk vorhanden.The present invention relates to an escalator or a moving walkway with at least one supporting structure, which is supported between the supports on a cable, which is arranged laterally as an auxiliary structure or under the supporting structure. The cable is also referred to as undervoltage. Usually, a supporting structure is present on both sides of the escalator or moving walk.
Solch eine Fahrtreppe bzw. ein Fahrsteig ist aus der
Nachteilig ist bei dieser bekannten Konstruktion, dass sich das Kabel dehnt, wenn sich das Tragwerk infolge einer Belastung durchbiegt und sich dadurch stärker an dem Kabel abstützt, sodass es dem Durchbiegen nicht ausreichend entgegenwirkt. Solch ein Durchbiegen ist aber nur in geringem Ausmaß zulässig, weil es sonst leicht zu Störungen in der Mechanik der Fahrtreppe bzw. des Fahrsteiges kommt.A disadvantage of this known construction that the cable stretches when the structure bends due to a load and thereby more strongly supported on the cable, so that it does not sufficiently counteract the bending. However, such bending is permissible only to a small extent, because otherwise it easily leads to disruptions in the mechanics of the escalator or the moving walk.
Es ist Aufgabe der vorliegenden Erfindung, eine Fahrtreppe bzw. einen Fahrsteig der eingangs genannten Art so weiterzubilden, dass die Tragwirkung der gesamten Konstruktion erhöht wird, d.h. sich unter Belastung weniger durchbiegt.It is an object of the present invention, an escalator or a moving walkway of the type mentioned in such a way that the supporting effect of the entire construction is increased, i. less flexes under load.
Diese Aufgabe wird durch eine Fahrtreppe bzw. einen Fahrsteig der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass im Bereich der Auflager jeweils ein Hebel vorgesehen ist, der am Tragwerk drehbar gelagert ist, der sich mit einem Arm gleitend am Bauwerk abstützt und an dessen anderen Arm das Kabel befestigt ist, so dass das Kabel bei zunehmender Belastung (Nutzlast) zusätzlich gespannt wird, und dadurch die Tragwirkung zunimmt.This object is achieved by an escalator or a moving walkway of the type mentioned in the present invention solved that in each case a lever is provided in the region of the support, which is rotatably mounted on the structure, which is slidably supported with one arm on the building and on the other arm, the cable is attached, so that the cable with increasing load (payload) in addition is tensioned, thereby increasing the bearing effect.
Dadurch, dass das Kabel stärker gespannt wird, wenn das Tragwerk belastet wird, wird die Spannung im Kabel erhöht, so dass das Haupttragwerk in den Unterstützungspunkten relativ angehoben wird.The fact that the cable is stretched more when the structure is loaded, the voltage in the cable is increased, so that the main structure is relatively raised in the support points.
Weitere Merkmale und Vorteile der Erfindung gehen aus der nachstehenden Beschreibung eines Ausführungsbeispiels anhand der beiliegenden Zeichnung hervor. Es zeigen:
-
Fig. 1 einen erfindungsgemäßen Fahrsteig von der Seite, und -
Fig. 2 ein Schnitt entlang der Linie II-II inFig. 1 .
-
Fig. 1 a moving walkway according to the invention from the side, and -
Fig. 2 a section along the line II-II inFig. 1 ,
Der Fahrsteig verbindet ein erstes Stockwerk mit einem zweiten Stockwerk. Er liegt über Auflager (nicht dargestellt) an den jeweiligen Geschoßdecken 10 bzw. 11 auf. Seitlich wird der Fahrsteig durch Balustraden 12, 13, zum Beispiel aus Glas, begrenzt, die oben einen Handlauf 14, 15 tragen. Zu beiden Seiten des Fahrsteigs befindet sich wie üblich ein Tragwerk 16, das als Fachwerk mit Obergurt 5 und Untergurt 6 ausgebildet ist. An den Enden des Tragwerks ist jeweils am Punkt 1 ein Hebel 2 gelagert, und zwar am Untergurt 6 oder in dessen Nähe. Dieser Hebel 2 stützt sich über ein Gleitlager 17, das als Dämpfungsplatte ausgebildet sein kann, an der jeweiligen Geschoßdecke 10 bzw. 11 ab. Am anderen Ende des Hebels 2 ist jeweils ein Ende eines Kabels 3 befestigt, das an den Unterstützungspunkten 4 mit dem Tragwerk 16 verbunden ist. Dieses Kabel 3 dient als Unterspannung.The moving walk connects a first floor with a second floor. He lies on supports (not shown) on the
Die vorliegende Erfindung funktioniert wie folgt: wenn der Fahrsteig stark belastet ist, beginnt sich das Tragwerk 16 durchzubiegen. Diesem Durchbiegen wirkt das Kabel 3 entgegen, auf dem sich das Tragwerk 16 an den Unterstützungspunkten 4 abstützt. Das Kabel 3 wird dadurch zusätzlich belastet, so dass es sich etwas dehnt. Infolge der Durchbiegung des Tragwerks 16 dehnt sich der Untergurt 6, und es verkürzt sich der Obergurt 5. Die Punkte 1, die am Untergurt 6 liegen, wandern daher etwas auseinander, das heißt jeweils in Richtung auf die benachbarte Geschoßdecke 10 bzw. 11 zu. Die unteren Enden der Hebel 2 gleiten dadurch in den Gleitlagern 17 etwas nach unten, und die beiden Hebel 2 drehen sich so, dass deren obere Enden sich stärker in Richtung zur jeweiligen Geschoßdecke 10 bzw. 11 bewegen als die Punkte 1. Dadurch wird das Kabel 3 gespannt, wodurch dann in den Unterstützungspunkten eine zusätzliche Unterstützugskraft ΔFu wirkt.The present invention works as follows: when the moving walk is heavily loaded, the
Insgesamt sind vier derartige Hebel 2 vorhanden, jeweils zwei zu beiden Seiten des Fahrsteiges am oberen und am unteren Ende. Die Konstruktion kann durch Diagonalstreben 18 (siehe
