Definitions
- the invention relates generally to an escalator or moving walk with at least one trim component.
- the invention particularly relates to the construction of the trim component of the escalator or moving walk and possible
- Escalators or moving walks have a load-bearing structure, which is called a supporting structure.
- this structure is a truss structure, which is divided by the manufacturer as a whole unit or in structural modules, is made.
- the structure or its structural modules or truss modules are installed in a building, the structure connects, for example, two levels of the building.
- the movable components of the escalator or the moving walk are arranged, for example, a step belt or a pallet belt,
- balustrades with their balustrade base, comb plates, bearings, raceways and guide rails with the structure or truss are firmly connected.
- Both the structure and the balustrade base are clad by means of trim components, possibly also has the balustrade cladding components.
- Escalators with clad balustrades are usually called
- Traffic stairs which are particularly used in high traffic areas such as train stations, subway stations and airports.
- trim components By lining the aforementioned components of a moving walkway or an escalator with trim components, an interior is delimited from the surroundings of the escalator or the moving walk. As a result, the components arranged in this interior are better protected against environmental influences such as, for example, dirt, moisture, snow and ice than if they were exposed.
- trim components also have the important function of preventing accidents, as they cover all movable components of the escalator or moving walk apart from the lead of the step or pallet band and the handrails.
- Base plates or the step band facing covers of the balustrade pedestal and / or the balustrade are exposed to constant mechanical stresses by the users, for example by scuffing shoes or items such as the sympathetic baggage. These covers must also withstand impact loads such as vandal hits and kicks to further ensure safe operation of the escalator or moving walkway.
- corrosion-resistant steel sheet or aluminum sheet is used for the production of these above-described, highly stressed trim components, which usually has a thickness of 1.5mm to 4.0mm.
- Replacing steel sheets is a less than satisfactory solution, because after a short time, the paint layer is scrubbed away and the burned areas not only the
- the object of the present invention is therefore to provide an escalator or a moving walk, whose cladding components are cheaper to produce and at least as well withstand the same loads as those from

- Cladding component of course other parts such as stiffening ribs,
- Reinforcement plates, fasteners and the like may have more.
- the individual layers all have the same areal extent, so the layer structure and the layer thicknesses are the same at every point of the composite steel sheet. At the edge regions and at cut edges of apertures, however, both the layer structure and the layer thicknesses can deviate as a result of machining processes.
- a cladding made of composite sheet steel not only has cost advantages. Due to its high chromium content, the cover layer made of corrosion-resistant steel is extraordinarily tough and abrasion-resistant, so that due to this material property and the layer thickness, which is many times greater than that of coatings, the cover layer is not damaged by abrasive objects such as luggage and shoes, but also by dirt and small stones can be removed.
- the cladding made of composite sheet metal offers even more efficient protection against environmental influences than a cladding component made entirely of corrosion-resistant steel, as it is directed against the interior
- Side surface which is usually the side surface of the supporting layer, can be easily adapted to the arranged in the interior components. In contrast to corrosion-resistant steel, low-alloyed steels can be coated much better and more permanently.
- the covering surface of the side surface of the supporting layer can therefore with a coating, preferably a copper layer, tin layer, zinc layer or Be provided plastic coating.
- a coating preferably a copper layer, tin layer, zinc layer or Be provided plastic coating.
- the coating is then directed against the interior. Since some cladding components are directly adjacent to a supporting structure or to a machine, the surface of which is usually hot-dip galvanized or provided with a zinc coating, the material is directed against the interior
- the surface of the load-bearing layer can be provided with a coating even before being joined to the cover layer to form a composite steel sheet.
- the composite steel sheet may include a polymer layer which is disposed between the supporting layer and the cover layer and firmly bonds them together.
- This polymer layer still has an extremely positive advantage.
- the structure provided with cladding components forms a resonance box whose resonant frequencies are in the range of those occurring during operation of the escalator or moving walk
- Vibrationsfrequencies can lie. Therefore, often damping mats, and damping elements must be installed to reduce the operating noise and noticeable to the user vibrations of the escalator or the moving walk.
- the polymer layer of the composite steel sheet already has vibration damping
- the polymer layer may have a thickness of 0.05mm to 4.0mm, preferably 0.5mm to 2.5mm. exhibit.
- the supporting layer and the covering layer can also be connected to each other by roll-plating.
- several, consisting of different materials layers can be arranged one above the other on the supporting layer.
- the side surfaces of the supporting layer may be hot-dip galvanized and the polymer layer and the cover layer on this be arranged hot-dip galvanized side surfaces.
- the supporting layer can also be provided by means of an adhesion-promoting coating, as it can be produced, for example, by phosphating.
- a cover layer made of corrosion-resistant steel can also be arranged on each side surface of the load-bearing layer.
- the cladding components may be made of composite steel sheets of different thicknesses.
- the supporting layer may for example have a thickness of 0.5 mm to 3.5 mm, preferably 0.8 mm to 1.5 mm and the cover layer may have a thickness of 0.03 mm to 1.5 mm, preferably 0.1 mm to 0.8 mm.
- the escalator or moving walk at least one interior, which is delimited by at least one trim component against the environment of the escalator or the moving walk.
- this does not mean that the interior is delimited from the environment only by one or more cladding components.
- At least the step band of the escalator or the pallet band of the moving walk also delimit the distance from the area, whereby
- System-related columns are present, can penetrate through the humid air, water and dirt in the interior.
- an escalator or a moving walkway also have a plurality of interiors, so that not all parts of the escalator or the moving walk are arranged in the same interior.
- the composite steel sheet may have at least one aperture for receiving fasteners.
- the at least one breakthrough can be made by means of a punch that shears under pressure in the
- the cover layer can also be pulled along here. Therefore, the cutting edge of the opening formed by the punching can be at least partially covered by the cover layer of the composite steel sheet.
- the at least one breach can also be made by means of a punch, which shears under pressure into the composite steel sheet and punched out the breakthrough and by means of an embossing die, the cold break deformed the molding, at least formed on the cutting edge.
- the embossing die can also form further contours in the region of the aperture, for example a countersink for the head of a screw serving as a fastener, a pre-extrusion directed against the interior as a spacer, or a bead encircling the aperture and the like directed towards the interior.
- a countersink for the head of a screw serving as a fastener for example a countersink for the head of a screw serving as a fastener, a pre-extrusion directed against the interior as a spacer, or a bead encircling the aperture and the like directed towards the interior.
- Cutting edge of the fürbmchs covering cover prevents the possibly corroding the bearing layer in the region of the cutting edge.
- a possible method for embossing a modifiches of the aforementioned type in a composite steel sheet of an escalator or a moving walkway may have the steps that first with a punch, the shearing under pressure in the
- the break-through at the cutting edge can then be cold stamped by means of an embossing stamp, wherein after embossing the cut edge of the opening formed by the stamping is covered by a cover layer of the composite steel sheet.
