Description

Die Erfindung betrifft eine Fahrtreppe oder einen Fahrsteig bestehend aus Balustrade mit Handlauf, Balustradensockel, Stufen bzw. Platten für den Transport von Personen und Gegenständen und aus Tragkörper und Führungsträger mit Führungen für die Stufen bzw. Platten und Handlauf.The invention relates to an escalator or moving walk consisting of balustrade with handrail, balustrade base, Steps or plates for the transport of people and Objects and from supporting body and guide carrier with Guides for the steps or plates and handrail.

Aus der Patentschrift CH 290983 ist eine Fahrtreppe bekannt geworden, bei der die Wände nach dem Grundsatz des Leichtbaus zur Bildung von Trägern verwendet werden, welche die Nutzlast und das Eigengewicht aufnehmen und auf die Auflager übertragen. Der durch Innenwand, Aussenwand, Obergurt, Untergurt gebildete Kastenträger ist in regelmässigen Abständen durch innere Querwände unterteilt, wodurch die Innenwand und Aussenwand gegen Ausknicken gesichert werden, wobei der Hohlkörper bei geringem Gewicht eine hohe Tragfähigkeit aufweist.An escalator is known from the patent specification CH 290983 in which the walls are built according to the principle of Lightweight construction can be used to form beams, which take up the payload and the dead weight and on the Transfer support. The through inner wall, outer wall, Upper flange, lower flange formed box girder is in regular intervals divided by inner transverse walls, whereby the inner wall and outer wall against buckling be secured, the hollow body with low weight has a high load-bearing capacity.

Ein Nachteil der bekannten Einrichtung liegt darin, dass sich diese Trägerkonstruktion lediglich für die Aufnahme von durch Nutzlast und Eigengewicht hervorgerufene vertikale Kräfte eignet.A disadvantage of the known device is that this support structure is only for recording caused by payload and dead weight vertical forces.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Fahrtreppe oder einen Fahrsteig mit einer über einen weiten Spannweitenbereich verdrehsteifen und quersteifen Konstruktion zu schaffen.The invention seeks to remedy this. The invention, as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and an escalator or moving walk with one over one wide range of torsional stiffness and transverse stiffness Creating construction.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass seitliche Kräfte hervorgerufen beispielsweise durch Erdbeben, Wind oder mutwillige Schwingungserregungen von Benutzern ohne Wirkung bleiben. Seitliche Ausweichungen wie auch Verwindungen des Tragkörpers sind auch bei zunehmender Spannweite der Fahrtreppe bzw. Fahrsteiges nicht möglich. Weiter vorteilhaft ist die einfache Tragkörperkonstruktion, die kein aufwendiges Fachwerk aufweist.The advantages achieved by the invention are in essential to see in that lateral forces caused for example by earthquakes, wind or wanton vibrations from users without effect stay. Side deviations as well as twists of the Supporting body are also with an increasing span Escalator or moving walk not possible. Further the simple support structure is advantageous has no elaborate truss.

In den Fig. 1 bis 7 ist mit 1 ein Fahrsteig bezeichnet, der ein erstes Stockwerk 2 mit einem zweiten Stockwerk 3 verbindet. Als Fördermittel für Personen und Gegenstände sind einen Steig bildende Platten 4 vorgesehen. Bei Fahrtreppen dienen anstelle der Platten 4 Stufen als Transportmittel. Seitlich wird der Fahrsteig 1 durch Balustraden 5 beispielsweise aus Glas begrenzt. Jede Balustrade 5 trägt einen sich mit der Geschwindigkeit der Platten 4 fortbewegender Handlauf 6. Als Tragmittel für die Platten 4 bzw. Stufen dient ein Tragkörper 7. In einem unteren Teil 8 des Tragkörpers 7 ist ein hohlkörperartiges Rückgrat 9 angeordnet, welches seitliche Kräfte aufnehmen kann und verdrehsteif ist.1 to 7, 1 is a moving walk that a first floor 2 with a second floor 3 combines. As funding for people and objects plates 4 forming a rise are provided. at Escalators serve as 4 steps instead of the plates Mode of Transport. Moving walk 1 is to the side Balustrades 5, for example made of glass. each Balustrade 5 carries you at the speed of Plates 4 moving handrail 6. As suspension for the A supporting body 7 is used for plates 4 or steps lower part 8 of the support body 7 is a hollow body Backbone 9 arranged, which absorb lateral forces can and is torsionally rigid.

Fig. 2 zeigt einen Querschnitt des Fahrsteiges 1 mit einem Rückgrat 9. Querstege 7.1 verbinden den linken Tragkörper 7 mit dem rechten Tragkörper 7. Am Tragkörper 7 ist eine Aussenverkleidung 10, ein Balustradensockel 11 und ein Führungsträger 12 angeordnet. Der Führungsträger 12 weist erste Führungen 12.1 für die vorlaufenden Platten 4, zweite Führungen 12.2 für die rücklaufenden Platten 4.1 und dritte Führungen 12.3 für den rücklaufenden Handlauf 6.1 auf.Fig. 2 shows a cross section of the moving walk 1 with a Backbone 9. Cross bars 7.1 connect the left support body 7 with the right support body 7. On the support body 7 is one Outer lining 10, a balustrade base 11 and one Guide bracket 12 arranged. The guide bracket 12 has first guides 12.1 for the leading plates 4, second Guides 12.2 for the return plates 4.1 and third Guides 12.3 for the returning handrail 6.1.

Das im unteren Teil 8 beispielsweise zwischen zwei Querstegen 7.1 angeordnete Rückgrat 9 besteht beispielsweise aus mindestens einer dünnwandigen in sich geschlossenen als Vierkantrohr ausgebildeten Blechkonstruktion 9.1, welche beispielsweise aus verschweissten Blechbiegeteilen gefertigt werden kann. Zur Aussteifung können in der Blechkonstruktion 9.1 Zwischenwände 9.2 eingezogen werden. Das Rückgrat 9 kann auch zwischen den vorlaufenden Platten 4 und den rücklaufenden Platten 4.1 angeordnet werden. Der Fahrsteig 1 bzw. die Fahrtreppe kann auch mehrere beispielsweise zwischen den Platten 4, 4.1 und im unteren Teil 8 des Tragkörpers 7 angeordnete Rückgrate 9 aufweisen. Das Rückgrat 9 kann auch aus mehreren nebeneinanderliegenden und/oder untereinanderliegenden Rohren bestehen. Auch vom Vierkantquerschnitt abweichende Rohrquerschnitte sind möglich, wobei das horizontale Flächenträgheitsmoment möglichst gross sein soll. Das zusätzliche Eigengewicht des Rückgrates 9 soll jedoch möglichst klein bleiben. In sich geschlossene Rohre sind extrem verdrehsteif, wodurch nicht nur seitliche Ausweichungen sondern auch Verwindungen des Tragkörpers 7 eliminiert werden. That in the lower part 8, for example, between two Crosspieces 7.1 arranged backbone 9 is made for example from at least one thin-walled in itself closed trained as a square tube Sheet metal construction 9.1, which, for example, from welded sheet metal parts can be manufactured. to Bracing in the sheet metal construction 9.1 Partitions 9.2 are retracted. The backbone 9 can also between the leading plates 4 and return plates 4.1 are arranged. The moving walk 1 or the escalator can also be several, for example between the plates 4, 4.1 and in the lower part 8 of the Carrying body 7 have arranged backbones 9. The Backbone 9 can also consist of several juxtaposed and / or pipes lying one below the other. Also from Square cross-section are different tube cross-sections possible, the horizontal area moment of inertia should be as large as possible. The additional weight of the Backbone 9 should remain as small as possible. In itself closed pipes are extremely torsionally rigid, which means that they do not only lateral deviations but also twists of the Carrier 7 are eliminated.

Fig. 3 zeigt einen Fahrsteig 1 mit einem innerhalb des Tragkörpers 7 angeordneten Rückgrat 9. Bei dieser Variante ist das Rückgrat 9 als Blech- oder Sandwichkonstruktion 9.1 ausgeführt und kann ausgeschäumt oder mit einem Füllmaterial 9.3 gefüllt sein.Fig. 3 shows a moving walk 1 with a within the Support body 7 arranged backbone 9. In this variant is the backbone 9 as a sheet metal or sandwich construction 9.1 executed and can be foamed or with a Filling material 9.3 to be filled.

Fig. 4 bis 7 zeigen einen Fahrsteig 1 mit einem unterhalb des Tragkörpers 7 bzw. ausserhalb des den Tragkörper 7 bildenden Fachwerkes angeordneten Rückgrat 9. Bei diesen Varianten ist das Rückgrat 9 als Blechkonstruktion 9.1 mit Profilrohren 9.4 oder als Sandwichkonstruktion ausgeführt und kann ausgeschäumt oder mit einem Füllmaterial 9.3 gefüllt sein. Bei dieser Anordnung ist eine seitenwindunempfindliche Formgebung möglich, was insbesondere bei im Freien angeordneten Fahrsteigen 1 wegen Windbelastungen von Bedeutung ist.4 to 7 show a moving walk 1 with one below of the support body 7 or outside of the support body 7 forming truss arranged backbone 9. In these Variants is the backbone 9 as a sheet metal construction 9.1 Profile tubes 9.4 or as a sandwich construction and can be foamed or with a filling material 9.3 be filled. In this arrangement there is one cross wind insensitive shaping possible, what especially with moving walkways 1 arranged outdoors Wind loads are important.
