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.
  • document US 2013/0163233 discloses an escalator according to the preamble of claim 1.
  • Escalators or moving walks have a load-bearing structure, referred to as 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 stepped belt or a pallet belt, deflection axes, a drive shaft and the drive motor with gearbox, its control, monitoring systems, security systems and the like. Furthermore, fixed components such as balustrades with their balustrade base, comb plates, bearings, raceways and guide rails with the structure or truss are firmly connected.
  • balustrade base 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 so-called traffic stairs, which are used especially in high-traffic areas such as 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.
  • trim components that delimit at least one interior of the escalator or the moving walk against the environment.
  • trim components such as pedestals or the step band facing covers of the balustrade pedestal and / or the balustrade, are subjected to constant mechanical stresses by the users, such as scouring shoes or items such as the carried luggage. 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.
  • 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 the cladding components made of corrosion-resistant sheet steel.
  • the trim component comprises at least one multilayer composite steel sheet, the composite steel sheet including at least one low alloy steel sheet bearing layer and at least one corrosion resistant steel overlay.
  • the at least one cover layer is arranged on one of the two side surfaces of the composite steel sheet, wherein the at least one cover layer of the mounted on the escalator or on the moving walkway trim component is directed against the environment.
  • the main component of the cladding component is the multilayer composite steel sheet, wherein the cladding component can of course have other parts such as stiffening ribs, reinforcing plates, fastening means and the like.
  • 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 component made of composite steel sheet offers even more efficient protection against environmental influences than a cladding component made entirely of corrosion-resistant steel, since the side surface directed towards the interior, which is usually the side surface of the supporting layer, is adapted in the simplest manner to the components arranged in the interior can. 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.
  • the coating is then directed against the interior. Since some cladding components directly adjoin a supporting structure or truss whose surface is usually hot-dip galvanized or provided with a zinc coating, the side surface of the supporting layer directed towards the interior is preferably provided with a zinc layer.
  • corrosion problems due to local formation of condensate can be avoided at the contact points between the supporting structure and the cladding component, since the contacting parts have the same potential in the electrochemical series of voltages.
  • 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.
  • trim components structure forms a resonance box whose resonance frequencies can be in the range of occurring during operation of the escalator or moving walk vibration frequencies. 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 properties, so that the cladding components already have sound-absorbing properties and possibly less or no sound-deadening measures are required. The thicker and more viscous the polymer layer is, the better the damping properties of the cladding component.
  • the polymer layer may have a thickness of 0.05 mm to 4.0 mm, preferably 0.5 mm to 2.5 mm.
  • 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 covering layer made of corrosion-resistant steel can also be arranged on each side surface of the supporting 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 stepped belt of the escalator or the pallet band of the moving walkway also delimit the interior from the environment, with systemic gaps are present through which humid air, water and dirt can penetrate into the interior.
  • At least one interior of the escalator or moving walk for example, the structure, parts of at least one Balustradensockels and / or parts of at least one balustrade can be arranged.
  • 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 opening for receiving fasteners.
  • the at least one breakthrough can be made by means of a punch that penetrates under shear pressure in the composite steel sheet and punched out the breakthrough.
  • 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 breakthrough can also by means of a punch, which penetrates under shear pressure in the composite steel sheet and punched out the breakthrough and by means of an embossing die, cold forming the breakthrough at least on the cutting edge, be made.
  • a punch which penetrates under shear pressure in the composite steel sheet and punched out the breakthrough
  • an embossing die cold forming the breakthrough at least on the cutting edge, be made.
  • 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 projection serving as a spacer, a projection directed towards the interior or a bead encircling the aperture and the like.
  • a cover layer covering the cut edge of the opening prevents the bearing layer from possibly corroding in the region of the cut edge.
  • a possible method for embossing a breakthrough of the aforementioned type in a composite steel sheet of an escalator or a moving walkway may comprise the steps of first piercing the opening with a punch that penetrates under shear pressure into the composite steel sheet.
  • the breakthrough at the cutting edge can then be stamped by cold stamping by means of an embossing stamp, wherein after embossing the cut edge of the opening formed by the blanking is covered by a cover layer of the composite steel sheet.
  • the embossing stamp thus presses the existing in the region of the cutting edge cover layer through the opening through to the side surface of the composite steel sheet, which is directed in the assembled state against the interior of the escalator or the moving walk.
  • the cut edges may also be sealed by other means, such as a drop of silicone sealant or an adhesive.
  • edges of the composite steel sheet may have cut edges that are also at least partially covered by the top layer of the composite steel sheet. As a result, as explained in connection with the cutting edge, the corroding of the cut edges is at least reduced.
  • One possible method for producing cut edges of the aforementioned type on a composite steel sheet of an escalator or moving walk may include the step of having a cutting tool having a fixed cutting edge and a movable cutting edge.
  • the fixed cutting edge and the movable cutting edge perform under shear an oblique cutting motion which extends at a shear angle to the vertical or vertical direction of the side surface of the composite steel sheet, so that during the shearing the cover layer is entrained by the movable cutting edge and thereby by the shearing formed cut edge of the composite steel sheet is covered by the entrained cover layer of the composite steel sheet.
  • the shear angle ⁇ can be between 0 ° to 30 ° with respect to the vertical.
  • a chamfer can be formed on the cutting edge of the movable cutting edge whose chamfer angle is aligned between -90 ° to 15 ° to the vertical or perpendicular of a side surface of the composite steel sheet.
  • the chamfer height of the chamfer can be between 0 to 3mm. Since corrosion-resistant steel has a high elongation at break, this material is extremely well suited to be pulled over the cutting edge by means of the aforementioned method.

Since corrosion-resistant steel has a high elongation at break, this material is extremely well suited to be pulled over the cutting edge 117 by means of the aforementioned method.
  • the cut edge 117 may be sealed with the same polymer material, for example by dipping or spraying.
  • the contours of existing from composite steel sheet 110 parts of a trim component 23/74 can also be worked out by water jet cutting or laser cutting. If the cut edges 117 machined in this way are likewise to be covered by the covering layer 114, the covering layer 114 can be rolled, for example by means of a rolling tool, over the cutting edge 117 or pressed or drawn over the cutting edge 117 by means of a pressing tool. However, the cut edge 117 can also be covered in a liquid-tight manner with a self-adhesive sealing strip or a liquid-applied, hardening polymer layer. The same naturally also applies to the cut edges 127 of the lining component 28/77.
  • FIGS. 7A and 7B show by means of in the FIG. 5 described covering component 28/77 various steps of producing a covered cut edge 126 of the opening 125th
  • the tool has a punch 150, a punch 151, and a die 152.
  • the composite steel sheet 120 of the trim member 28/77 is placed on the die die 152 and aligned. Subsequently, as in the FIG. 7A symbolized by the arrow in the axial direction F 1 , punched out by means of the punch 150 of the opening 125. Since an opening 125 for a countersunk screw is to be created in the present example, this opening 125 has a circular cross-sectional area, which is why the punch 150 and the punch 151 are rotationally symmetrical.
  • the stamper 151 is tubular, wherein the shaft 154 of the punch 150 is disposed in the bore 155 of the stamper 151. By this arrangement, the punch 151 is guided linearly by the shaft 154.
  • the stamper 151 is delivered against the Gensenk matrix 152 after the use of the punch 150.
  • the stamping die 151 has an embossing surface 156 in order to press the material of the composite steel sheet 120 into a recess 157 of the die matrix 152.
  • the bearing layer 129 is deformed in the region of the opening 125 in such a way that a conical seat for the screw head is formed.
  • the cover layer 124 facing the stamping die 151 is pulled over the cutting edge 126 previously produced by the punch 150 and thus the Cutting edge 126 covered by the cover layer 124.
  • this point can be sealed by means of a silicone sealant.
