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.

- the cladding component 23/74 which bears against the receiving plate 101 and serves as a side wall is made from a composite steel sheet 110 which has a supporting layer 119 made of low-alloy steel sheet, for example of a carbon steel or structural steel.
- a coating 112 preferably a zinc layer, for example, by hot-dip galvanizing, powder coating, by galvanic coating method or by spraying a zinc-containing paint applied. Since the receiving plate 101 is protected by means of a zinc layer 104 from corrosion, are two components to each other, whose surfaces with respect to the electrochemical series have no potential difference.
- the coating 112 may also be a tin layer or plastic coating.
- the side surface 113 of the cladding component 23/74 directed against the surroundings of the escalator 1 or the moving walk 50 has a cover layer 114 of corrosion-resistant steel, for example high-alloy chromium-nickel steel, which is connected, for example, by a polymer layer to the supporting layer 119.
- the polymer layer of the aforementioned type must have viscoelastic properties so that the composite steel sheet 110 can also be cold-worked without the individual layers 119, 114 detaching from one another (delaminating).
- a mixture of a rubber-containing first dispersion with an acrylic acid ester copolymer and a colloidal second dispersion of a chloropenpolymer for bonding the supporting layer 119 and the cover layer 114 can be used.
- epoxy resins or moisture-crosslinking polyurethane adhesives or sealants for elastomers are suitable for the intended use.
- the cover layer 114 may also be connected to the supporting layer 119 by roll-plating.
- the cladding component 28/77 serving as a cover of the balustrade pedestal 13/64 is made of a composite steel sheet 120 which has a cover layer 122, 124 of corrosion-resistant steel on both side surfaces 121, 123 of its supporting layer 129 made of low-alloy sheet steel.
- the two cover layers 122, 124 may be glued to the supporting layer 129 or connected by means of roll cladding. Since the two cladding components 28/77 and 23/74 touch with their made of corrosion-resistant steel cover layers 114, 122 in the region of the countersunk screw 103, no potential difference is here also with respect to the electrochemical voltage series available.
- the countersunk screw 103 is made of corrosion-resistant steel.
- both cladding components 28/77, 23/74 are fastened to the receiving plate 101 by means of a countersunk screw 103, both have an opening 115, 125 assigned to this countersunk screw 103.
- the opening 125 of the covering component 28/77 serving as a cover has a conically shaped by embossing formation, which receives the head of the countersunk screw 103 so that it does not protrude.
- the cut edges 116, 126 of both apertures 115, 125 are covered by the respective cover layer 114, 124. Therefore, the opening 115 of serving as a side wall cladding component 23/74 is conical.
- the cut edges 117, 127 at the edge regions of the lining components 28/77, 23/74 are also covered by the covering layer 114, 124 directed towards the surroundings. Two examples of how cut edges covered by the cover layer are described below are described.
- FIGS. 6A to 6C show by means of in the FIG. 5 described covering components 23/74 various stages of a possible production covered cut edges 117 in its edge regions.
- FIGS. 6A to 6C Not only the supporting layer 119, the covering layer 114 and the coating 112 are shown, but also the polymer layer 118, which firmly connects the covering layer 114 with the supporting layer 119. From that in the FIGS. 6A to 6C shown cutting tool only a fixed blade 140 and a movable blade 141 is shown. Basically, this cutting tool hardly differs from conventional sheet metal shears. When shearing performs the movable blade 141 relative to the fixed blade 140, however, an oblique cutting movement Z at a shear angle ⁇ relative to the vertical V or perpendicular V of the side surface 113, or to the thickness of the composite steel sheet 110 of the cladding component 23/74.
- a chamfer 143 is formed on the cutting edge 142 of the movable blade 141.
- the chamfer 143 has a chamfer height P and is arranged at the chamfer angle ⁇ to the thickness of the composite steel sheet 110, or to the vertical V of the side surface 113, at the cutting edge 142 of the movable blade 141.
- a chamfer edge 144 is present, which is aligned with the inclusion of the cutting movement Z exactly to a sharp cutting edge 146 of the fixed cutting edge 140.
- the chamfer height P and its chamfer angle ⁇ must be matched to the material properties of the composite steel sheet 110 to be cut and the shear angle ⁇ , whereby the ideal values can be empirically determined by means of experiments.
- the shear angle ⁇ between 0 ° to 30 °, the chamfer angle ⁇ between -90 ° to 15 ° and the chamfer height P between 0 and 2mm can be selected.
- the shear angle ⁇ between 5 ° to 20 °, the chamfer angle ⁇ between -85 ° to -60 ° and the chamfer height P between 0.5mm and 1.0mm.
- the angle values are given in the clockwise direction with positive, the angle values in the counterclockwise direction with a negative sign.
- the cover layer 114 is not smoothly cut during shearing due to the oblique cutting movement Z and the chamfer 143, but pulled along during the shearing by the movable blade 141. Since the fixed cutting edge 140 has a sharp-edged cutting edge 146, the coating 112 and the supporting layer 119 are cut through there until the edge of the blade 144 passes by the cutting edge 146.
- the covering layer 114 which has become considerably thinner due to the drawing in this region, is also severed, as shown in FIG. 6C is shown.
- the cut edge 117 of the composite steel sheet 110 formed by the shearing is covered or covered by the cover layer 114 of the composite steel sheet 110. 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.

Description
Die Erfindung betrifft allgemein eine Fahrtreppe oder einen Fahrsteig mit mindestens einem Verkleidungsbauteil. Die Erfindung betrifft insbesondere den Aufbau des Verkleidungsbauteils der Fahrtreppe oder Fahrsteiges. Dokument
Sowohl das Tragwerk als auch die Balustradensockel sind mittels Verkleidungsbauteilen verkleidet, gegebenenfalls weist auch die Balustrade Verkleidungsbauteile auf. Fahrtreppen mit verkleideten Balustraden sind üblicherweise sogenannte Verkehrstreppen, die insbesondere in stark frequentierten Bereichen wie beispielsweise in Bahnhöfen, U-Bahn Stationen und Flughäfen Verwendung finden.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.
Durch die Verkleidung der vorgenannten Komponenten eines Fahrsteiges oder einer Fahrtreppe mit Verkleidungsbauteilen wird ein Innenraum gegen die Umgebung der Fahrtreppe oder des Fahrsteiges abgegrenzt. Dadurch sind die in diesem Innenraum angeordneten Komponenten vor Umwelteinflüssen wie beispielsweise Schmutz, Nässe, Schnee und Eis besser geschützt, als wenn sie freiliegend wären. Die Verkleidungsbauteile haben allerdings auch die wichtige Funktion, Unfälle zu verhindern, da sie abgesehen vom Vorlauf des Stufen- oder Palettenbandes und den Handläufen alle bewegbaren Komponenten der Fahrtreppe oder des Fahrsteiges abdecken.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. The However, 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.
Aus diesen Gründen weisen alle Fahrtreppen und Fahrsteige Verkleidungsbauteile auf, die mindestens einen Innenraum der Fahrtreppe oder des Fahrsteiges gegen die Umgebung abgrenzen. Einige dieser Verkleidungsbauteile wie beispielsweise Sockelbleche oder dem Stufenband zugewandte Abdeckungen des Balustradensockels und/oder der Balustrade sind dauernden mechanischen Belastungen durch die Benutzer ausgesetzt, beispielsweise durch scheuernde Schuhe oder Gegenstände wie das mitgeführte Gepäck. Diese Abdeckungen müssen auch stoßartigen Belastungen wie Schlägen und Tritten von Vandalen standhalten, um weiterhin den sicheren Betrieb der Fahrtreppe oder des Fahrsteiges gewährleisten zu können.For these reasons, all escalators and moving walks on trim components that delimit at least one interior of the escalator or the moving walk against the environment. Some of these 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.
Aufgrund dieser Anforderungen wird zur Herstellung dieser vorangehend beschriebenen, stark beanspruchten Verkleidungsbauteile korrosionsbeständiges Stahlblech oder Aluminiumblech verwendet, welches üblicherweise eine Dicke von 1.5mm bis 4.0mm aufweist.Because of these requirements, 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.
Dieses sehr teure Material durch andere Materialien wie beispielsweise lackierte Stahlbleche zu ersetzen, ist eine wenig befriedigende Lösung, da schon nach kurzer Zeit die Lackschicht weggescheuert ist und die blankgescheuerten Stellen nicht nur das Erscheinungsbild der Fahrtreppe oder des Fahrsteiges beeinträchtigen, sondern bei den Benutzern auch ein wenig vertrauenswürdiges Bild hinterlassen. Andere Materialien wie beispielsweise Kunststoffplatten oder Aluminiumbleche werden aufgrund ihrer weichen Oberfläche rasch zerkratzt und abgetragen und müssen auch eine größere Wandstärke aufweisen, um denselben stoßartigen Belastungen standhalten zu können, wie die aus korrosionsbeständigem Stahlblech gefertigten Verkleidungsbauteile.To replace this very expensive material with other materials such as painted steel sheets, is a less than satisfactory solution, since after a short time, the paint layer is scrubbed away and the burned spots affect not only the appearance of the escalator or the moving walk, but among the users also leave little trusted picture. Other materials such as plastic sheets or aluminum sheets are rapidly scratched and worn due to their soft surface and must also have a greater wall thickness to withstand the same impact loads as the cladding members made of corrosion resistant sheet steel.
Die Aufgabe der vorliegenden Erfindung ist daher, eine Fahrtreppe oder einen Fahrsteig zu schaffen, deren Verkleidungsbauteile kostengünstiger herstellbar sind und die zumindest gleich gut dieselben Belastungen aushalten, wie die aus korrosionsbeständigem Stahlblech gefertigten Verkleidungsbauteile.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.
Diese Aufgabe wird gelöst durch eine Fahrtreppe oder einen Fahrsteig mit mindestens einem Innenraum, der durch mindestens ein Verkleidungsbauteil gegen die Umgebung der Fahrtreppe oder des Fahrsteiges abgegrenzt ist. Das Verkleidungsbauteil weist mindestens ein mehrschichtiges Verbundstahlblech auf, wobei das Verbundstahlblech mindestens eine tragende Schicht aus niedriglegiertem Stahlblech und mindestens eine Deckschicht aus korrosionsbeständigem Stahl beinhaltet. Die mindestens eine Deckschicht ist an einer der beiden Seitenflächen des Verbundstahlblechs angeordnet, wobei die mindestens eine Deckschicht des an der Fahrtreppe oder am Fahrsteig montierten Verkleidungsbauteils gegen die Umgebung gerichtet ist. Hauptbestandteil des Verkleidungsbauteils ist das mehrschichtige Verbundstahlblech, wobei das Verkleidungsbauteil selbstverständlich weitere Teile wie Versteifungsrippen, Verstärkungsbleche, Befestigungsmittel und dergleichen mehr aufweisen kann. Die einzelnen Schichten weisen alle dieselbe flächige Erstreckung auf, somit sind der Schichtaufbau und die Schichtdicken an jeder Stelle des Verbundstahlbleches gleich. An den Randbereichen und bei Schnittkanten von Durchbrüchen können aber sowohl der Schichtaufbau als auch die Schichtdicken infolge von Bearbeitungsprozessen abweichen.This object is achieved by an escalator or moving walk with at least one interior, which is delimited by at least one trim component against the environment of the escalator or the moving walk. 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.
Ein aus Verbundstahlblech gefertigtes Verkleidungsbauteil weist nicht nur Kostenvorteile auf. Die aus korrosionsbeständigem Stahl bestehende Deckschicht ist aufgrund ihres hohen Chromanteils außerordentlich zäh und scheuerresistent, so dass durch diese Materialeigenschaft und die im Vergleich zu Beschichtungen um ein Vielfaches stärkere Schichtdicke die Deckschicht durch schleifende Gegenstände wie Gepäckstücke und Schuhe, aber auch durch Schmutz und kleine Steine nicht abgetragen werden kann.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.
Zudem bietet das aus Verbundstahlblech gefertigte Verkleidungsbauteil einen noch effizienteren Schutz gegen Umwelteinflüsse, als ein komplett aus korrosionsbeständigem Stahl gefertigtes Verkleidungsbauteil, da die gegen den Innenraum gerichtete Seitenfläche, welche üblicherweise die Seitenfläche der tragenden Schicht ist, auf einfachste Weise den im Innenraum angeordneten Bauteilen angepasst werden kann. Im Unterschied zu korrosionsbeständigem Stahl lassen sich nämlich niedriglegierte Stähle deutlich besser und dauerhafter mit einer Beschichtung versehen.In addition, 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.
Die der Deckschicht gegenüberliegende Seitenfläche der tragenden Schicht kann daher mit einer Beschichtung, vorzugsweise einer Kupferschicht, Zinnschicht, Zinkschicht oder Kunststoffbeschichtung versehen sein. In montiertem Zustand ist dann die Beschichtung gegen den Innenraum gerichtet. Da einige Verkleidungsbauteile direkt an ein Tragwerk beziehungsweise Fachwerk angrenzen, dessen Oberfläche meistens feuerverzinkt oder mit einem Zinkanstrich versehen ist, wird die gegen den Innenraum gerichtete Seitenfläche der tragenden Schicht vorzugsweise mit einer Zinkschicht versehen. Dadurch können an den Berührungsstellen zwischen dem Tragwerk und dem Verkleidungsbauteil Korrosionsprobleme infolge lokaler Kondensat- Bildung vermieden werden, da die sich berührenden Teile dasselbe Potential in der elektrochemischen Spannungsreihe aufweisen. Die Oberfläche der tragenden Schicht kann selbstverständlich schon vor dem Zusammenfügen mit der Deckschicht zu einem Verbundstahlblech mit einer Beschichtung versehen sein.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. In the assembled state, 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. As a result, 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. Of course, 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.
Es stehen verschiedene Möglichkeiten offen, um die tragende Schicht und die Deckschicht dauerhaft zusammenzufügen. Beispielsweise kann das Verbundstahlblech eine Polymerschicht beinhalten, welche zwischen der tragenden Schicht und der Deckschicht angeordnet ist und diese miteinander fest verbindet. Diese Polymerschicht hat noch einen außerordentlich positiven Vorteil. Das mit Verkleidungsbauteilen versehene Tragwerk bildet einen Resonanzkasten, dessen Resonanzfrequenzen im Bereich der beim Betrieb der Fahrtreppe oder des Fahrsteiges auftretenden Vibrationsfrequenzen liegen können. Daher müssen oftmals Dämpfungsmatten und Dämpfungselemente eingebaut werden, um die Betriebsgeräusche und die für den Benutzer spürbaren Vibrationen der Fahrtreppe oder des Fahrsteiges zu reduzieren. Die Polymerschicht des Verbundstahlbleches weist bereits schwingungsdämpfende Eigenschaften auf, so dass die Verkleidungsbauteile bereits über schalldämpfende Eigenschaften verfügen und gegebenenfalls weniger oder gar keine Schalldämpfungs-Maßnahmen erforderlich sind. Je dicker und zähelastischer die Polymerschicht ist, desto besser sind die Dämpfungseigenschaften des Verkleidungsbauteils. Die Polymerschicht kann eine Stärke von 0.05mm bis 4.0mm, vorzugsweise 0.5mm bis 2.5mm aufweisen.There are various options available for permanently joining the load-bearing layer and the cover layer. For example, 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. Provided with 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.
Selbstverständlich können die tragende Schicht und die Deckschicht auch durch Walzplattieren miteinander verbunden werden. Zudem können auf der tragenden Schicht auch mehrere, aus unterschiedlichen Materialien bestehende Schichten übereinander angeordnet sein. Beispielsweise können die Seitenflächen der tragenden Schicht feuerverzinkt sein und die Polymerschicht und die Deckschicht auf diesen feuerverzinkten Seitenflächen angeordnet sein. Die tragende Schicht kann aber auch mittels einer haftvermittelnden Beschichtung versehen sein, wie sie beispielsweise durch Phosphatieren erzeugbar ist. Ferner kann auch auf jeder Seitenfläche der tragenden Schicht eine aus korrosionsbeständigem Stahl bestehende Deckschicht angeordnet sein.Of course, the supporting layer and the covering layer can also be connected to each other by roll-plating. In addition, several, consisting of different materials layers can be arranged one above the other on the supporting layer. For example, 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. However, the supporting layer can also be provided by means of an adhesion-promoting coating, as it can be produced, for example, by phosphating. Furthermore, a covering layer made of corrosion-resistant steel can also be arranged on each side surface of the supporting layer.
Je nach den mechanischen Anforderungen können die Verkleidungsbauteile aus Verbundstahlblechen unterschiedlicher Stärke gefertigt sein. Die tragende Schicht kann beispielsweise eine Stärke von 0.5 mm bis 3.5 mm, vorzugsweise 0.8 mm bis 1.5 mm aufweisen und die Deckschicht kann eine Stärke von 0.03 mm bis 1.5 mm, vorzugsweise 0.1 mm bis 0.8 mm aufweisen.Depending on the mechanical requirements, 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.
Wie weiter oben erwähnt, weist die Fahrtreppe oder der Fahrsteig mindestens einen Innenraum auf, der durch mindestens ein Verkleidungsbauteil gegen die Umgebung der Fahrtreppe oder des Fahrsteiges abgegrenzt ist. Dies bedeutet aber nicht, dass der Innenraum nur durch ein, oder mehrere Verkleidungsbauteile gegen die Umgebung abgegrenzt ist. Zumindest das Stufenband der Fahrtreppe oder das Palettenband des Fahrsteiges grenzen den Innenraum ebenfalls von der Umgebung ab, wobei systembedingte Spalten vorhanden sind, durch die feuchte Luft, Wasser und Schmutz in den Innenraum eindringen können.As mentioned above, 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. However, 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.
Im mindestens einen Innenraum der Fahrtreppe oder des Fahrsteiges können beispielsweise das Tragwerk, Teile mindestens eines Balustradensockels und/oder Teile mindestens einer Balustrade angeordnet sein. Selbstverständlich kann eine Fahrtreppe oder ein Fahrsteig auch mehrere Innenräume aufweisen, so dass nicht alle Teile der Fahrtreppe oder des Fahrsteiges in demselben Innenraum angeordnet sind.In 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. Of course, 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.
Selbstverständlich kann das Verbundstahlblech mindestens einen Durchbruch zur Aufnahme von Befestigungsmittel aufweisen. Der mindestens eine Durchbruch kann mittels eines Stanzstempels gefertigt werden, der unter Druck scherend in das Verbundstahlblech eindringt und den Durchbruch ausstanzt. Je nach Ausgestaltung des Stanzstempels kann auch hier die Deckschicht mitgezogen werden. Daher kann die durch das Ausstanzen gebildete Schnittkante des Durchbruchs durch die Deckschicht des Verbundstahlbleches zumindest teilweise abgedeckt sein.Of course, 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. Depending on the configuration of the punch, 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.
Der mindestens eine Durchbruch kann aber auch mittels eines Stanzstempels, der unter Druck scherend in das Verbundstahlblech eindringt und den Durchbruch ausstanzt und mittels eines Prägestempels, der den Durchbruch zumindest an der Schnittkante prägend kaltverformt, gefertigt sein. Durch diese Fertigungsmethode kann erreicht werden, dass nach dem Prägen die durch das Ausstanzen gebildete Schnittkante des Durchbruchs nahezu vollständig durch die aus korrosionsbeständigem Stahl bestehende Deckschicht des mehrschichtigen Verbundstahlbleches abgedeckt ist. Der Prägestempel kann im Bereich des Durchbruchs auch weitere Konturen formen, beispielsweise eine Senkung für den Kopf einer als Befestigungsmittel dienenden Schraube, einen als Distanzhalter dienenden, gegen den Innenraum gerichteten Vorsprung oder eine gegen den Innenraum gerichtete den Durchbruch umlaufende Sicke und dergleichen mehr. Eine die Schnittkante des Durchbruchs abdeckende Deckschicht verhindert, dass gegebenenfalls die tragende Schicht im Bereich der Schnittkante korrodiert.But 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. By this manufacturing method can be achieved that after embossing the cut edge of the opening formed by the punching is almost completely covered by the existing of corrosion-resistant steel cover layer of the multilayer composite steel sheet. 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.
Ein mögliches Verfahren zum Prägestanzen eines Durchbruches der vorgenannten Art in einem Verbundstahlblech einer Fahrtreppe oder eines Fahrsteiges kann die Schritte aufweisen, dass zuerst mit einem Stanzstempel, der unter Druck scherend in das Verbundstahlblech eindringt, der Durchbruch ausgestanzt wird. In einem zweiten Schritt kann dann mittels eines Prägestempels der Durchbruch an der Schnittkante prägend kaltverformt werden, wobei nach dem Prägen die durch das Ausstanzen gebildete Schnittkante des Durchbruchs durch eine Deckschicht des Verbundstahlbleches abgedeckt ist. Der Prägestempel drückt somit die im Bereich der Schnittkante vorhandene Deckschicht durch den Durchbruch hindurch bis zur der Seitenfläche des Verbundstahlbleches, die in montiertem Zustand gegen den Innenraum der Fahrtreppe oder des Fahrsteiges gerichtet ist. Selbstverständlich können die Schnittkanten auch mit anderen Mitteln versiegelt werden, beispielsweise mit einem Tropfen Silikondichtmasse oder einem Klebstoff.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. In a second step, 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. Of course, the cut edges may also be sealed by other means, such as a drop of silicone sealant or an adhesive.
Eine besonders präzise und rasche Herstellung der Durchbrüche gelingt dann, wenn der Prägestempel konzentrisch den Stanzstempel umgreift und beide Stempel unabhängig voneinander in Axialrichtung verschoben werden können. Dadurch müssen die Durchbrüche nicht durch zwei voneinander getrennte Werkzeugstationen gefertigt werden.A particularly precise and rapid production of breakthroughs succeeds when the punch concentrically surrounds the punch and both punches can be moved independently in the axial direction. As a result, the openings do not have to be made by two separate tool stations.
Die Ränder des Verbundstahlblechs können Schnittkanten aufweisen, die auch zumindest teilweise durch die Deckschicht des Verbundstahlbleches abgedeckt sind. Dadurch wird wie schon in Zusammenhang mit der Schnittkante erklärt, das Korrodieren der Schnittkanten zumindest reduziert.The 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.
Ein mögliches Verfahren zum Herstellen von Schnittkanten der vorgenannten Art an einem Verbundstahlblech einer Fahrtreppe oder eines Fahrsteiges kann den Schritt aufweisen, dass ein Schneidewerkzeug vorhanden ist, das eine feste Schneide und eine bewegliche Schneide aufweist. Die feste Schneide und die bewegliche Schneide vollführen unter Druck scherend eine schräge Schnittbewegung, die in einem Scherwinkel zur Vertikalen beziehungsweise zur lotrechten Richtung der Seitenfläche des Verbundstahlblechs verläuft, so dass während des Scherens die Deckschicht durch die bewegliche Schneide mitgezogen wird und dadurch die durch das Scheren gebildete Schnittkante des Verbundstahlblechs durch die mitgezogene Deckschicht des Verbundstahlbleches abgedeckt ist.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.
Der Scherwinkel α kann zwischen 0° bis 30° bezüglich der Vertikalen sein. Um beim Scheren das Mitziehen der Deckschicht zu unterstützen, kann an der Schneidekante der beweglichen Schneide eine Fase ausgebildet sein, deren Fasenwinkel zwischen -90° bis 15° zur Vertikalen beziehungsweise Lotrechten einer Seitenfläche des Verbundstahlblechs ausgerichtet ist. Die Fasenhöhe der Fase kann zwischen 0 bis 3mm sein. Da korrosionsbeständiger Stahl eine hohe Bruchdehnung aufweist, ist dieses Material außerordentlich gut geeignet, mittels des vorgenannten Verfahrens über die Schnittkante gezogen zu werden.The shear angle α can be between 0 ° to 30 ° with respect to the vertical. In order to support the pulling of the cover layer during shearing, 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.

Der Fahrsteig 50 kann auch auf einen flachen Fußboden ohne Grube 65 montiert werden, wenn dieser zwischen zwei Rampen angeordnet ist. Die beiden Rampen sind empfehlenswert, damit die Benutzer bequem auf die Höhe beziehungsweise auf das Niveau des Palettenbandes 58 des Fahrsteiges 50 gelangen können.The moving
Der Fußboden 51 weist Aufnahmen 52 auf, an denen die Bauteile des Fahrsteiges 50 befestigt werden. Zu diesen Bauteilen gehören ein erster Umlenkbereich 53 und ein zweiter Umlenkbereich 54 sowie zwischen den Umlenkbereichen 53, 54 angeordnete Stützstrukturen 55, Laufschienen 56, Balustraden 57 mit Balustradensockel 64 und das umlaufende Palettenband 58. Da ein Teil des Fahrsteiges 50 in der Grube 65 eingelassen ist, muss nur der das Bodenniveau N1 - N2 des Fußbodens 51 überragende Teil des Fahrsteiges 50 mit Verkleidungsbauteilen 71, 72, 73, 74, 75, 76 verkleidet sein.The

Jedes dieser Verkleidungsbauteile 23, 27, 28, 33, 34, 35 weist mindestens ein mehrschichtiges Verbundstahlblech 40 auf, wobei das Verbundstahlblech 40 mindestens eine tragende Schicht 42 aus niedriglegiertem Stahlblech und eine Deckschicht 41 aus korrosionsbeständigem Stahl beinhaltet. Aus Übersichtsgründen ist nur das als Untersicht dienende Verkleidungsbauteil 27 mit den entsprechenden Bezugszeichen versehen. Die Deckschicht 41 ist an einer der beiden Seitenflächen 43, 44 des Verbundstahlblechs 40 angeordnet. Die tragende Schicht 42 muss nicht zwingend bei allen Verkleidungsbauteilen 23, 27, 28, 33, 34, 35 gleich stark beziehungsweise dick sein. Deren Dicke beziehungsweise Stärke kann den jeweiligen zu erwartenden Belastungen angepasst gewählt werden. So kann beispielsweise die tragende Schicht des gegen das Stufenband 11 gerichteten Verkleidungsbauteils 34 der Balustrade 12 dicker sein, als die tragende Schicht 42 des als Untersicht dienenden Verkleidungsbauteils 27, weil im Bereich der Balustraden 12 wesentlich größere Belastungen wie beispielsweise Stöße und Schläge von Benutzern zu erwarten sind. In montiertem Zustand sind die aus korrosionsbeständigem Stahl bestehenden Deckschichten 41 aller Verkleidungsbauteile 23, 27, 28, 33, 34, 35 gegen die Umgebung der Fahrtreppe 1 gerichtet.Each of these

Auch der Balustradensockel 13 weist aus Stahlprofilen gefertigte Sockelteile 49 auf, an denen die als Sockelbleche dienenden Verkleidungsbauteile 35 und die als Abdeckungen dienenden Verkleidungsbauteile 28 befestigt sind. Um sauber gestaltete Eckabschlüsse zu erhalten, können zwischen den seitlichen Verkleidungsbauteilen und dem als Untersicht dienenden Verkleidungsbauteil 27 Winkelprofile 30 angeordnet sein, die sich in ihrer Längserstreckung vorzugsweise über mehrere nebeneinander angeordnete Verkleidungsbauteile 23 und 27 erstrecken.

Wie der Schnitt B-B zeigt, sind die Stützstrukturen 55 bis zum Bodenniveau N1 - N2 und die Balustradensockel 64 mit den Verkleidungsbauteilen 74, 77, 78 verkleidet, so dass durch die Verkleidungsbauteile 74, 77, 78 sowie durch die Grubenwände 51A der festen Struktur 51 und das Palettenband 58 ein Innenraum 79 gegen die Umgebung des Fahrsteiges 50 abgegrenzt ist.Further, 55 other parts of the

Der Ausschnitt D zeigt eine Ecke des Balustradensockels 13/64 der Fahrtreppe 1 beziehungsweise des Fahrsteiges 50. Am Sockelteil 49 beziehungsweise an der Stütze 66 ist eine Aufnahmeplatte 101 angeschweißt, die eine Gewindebohrung 102 zur Aufnahme einer Senkkopfschraube 103 aufweist. Selbstverständlich kann die Aufnahmeplatte 101 auch angeschraubt, geclincht, genietet oder ganz einfach am Sockelteil 49 beziehungsweise an der Stütze 66 angeformt sein.The detail D shows a corner of the
An der Aufnahmeplatte 101 sind ein als Abdeckung dienendes Verkleidungsbauteil 28/77 und ein als Seitenwand dienendes Verkleidungsbauteil 23/74 mittels derselben Senkkopfschraube 103 befestigt. Logischerweise sind in der Längserstreckung des Fahrsteiges 50 oder der Fahrtreppe 1 eine Reihe von Senkkopfschrauben 103 in vorgegebenen Abständen vorgesehen, um die beiden Verkleidungsbauteile 23/74, 28/77 zu befestigen.On the receiving
Das der Aufnahmeplatte 101 anliegende, als Seitenwand dienende Verkleidungsbauteil 23/74 ist aus einem Verbundstahlblech 110 gefertigt, welches eine tragende Schicht 119 aus niedriglegiertem Stahlblech, beispielsweise aus einem Kohlenstoffstahl beziehungsweise Baustahl aufweist. Auf seiner gegen den Innenraum 19/79 gerichteten Seitenfläche 111 ist eine Beschichtung 112, vorzugsweise eine Zinkschicht, beispielsweise durch Feuerverzinken, Pulverbeschichten, durch galvanische Beschichtungsverfahren oder durch Aufspritzen einer zinkhaltigen Farbe aufgebracht. Da auch die Aufnahmeplatte 101 mittels einer Zinkschicht 104 vor Korrosionseinflüssen geschützt ist, liegen zwei Bauteile einander an, deren Oberflächen bezüglich der elektrochemischen Spannungsreihe keinen Potentialunterschied aufweisen. Selbstverständlich kann die Beschichtung 112 auch eine Zinnschicht oder Kunststoffbeschichtung sein.The
Die gegen die Umgebung der Fahrtreppe 1 oder des Fahrsteiges 50 gerichtete Seitenfläche 113 des Verkleidungsbauteils 23/74 weist eine Deckschicht 114 aus korrosionsbeständigem Stahl, beispielsweise hochlegiertem Chrom-Nickelstahl auf, welche beispielsweise durch eine Polymerschicht mit der tragenden Schicht 119 verbunden ist. Die Polymerschicht der vorgenannten Art muss zähelastische Eigenschaften aufweisen, damit das Verbundstahlblech 110 auch kaltverformt werden kann, ohne dass sich die einzelnen Schichten 119, 114 voneinander ablösen (delaminieren). Beispielsweise kann eine Mischung aus einer kautschukhaltigen ersten Dispersion mit einem Acrylsäureestercopolymer und einer kolloidalen zweiten Dispersion eines Chloropenpolymerisates zur Verklebung der tragenden Schicht 119 und der Deckschicht 114 eingesetzt werden. Ferner sind auch Epoxydharze oder zu Elastomeren feuchtvernetzende Polyurethanklebstoffe beziehungsweise -dichtmaßen für den vorgesehen Verwendungszweck geeignet. Selbstverständlich kann die Deckschicht 114 auch mittels Walzplattieren mit der tragenden Schicht 119 verbunden sein.The
Das als Abdeckung des Balustradensockels 13/64 dienende Verkleidungsbauteil 28/77 ist aus einem Verbundstahlblech 120 gefertigt, welches auf beiden Seitenflächen 121, 123 seiner aus niedriglegiertem Stahlblech gefertigten, tragenden Schicht 129 je eine Deckschicht 122, 124 aus korrosionsbeständigem Stahl aufweist. Wie bereits oben beschrieben, können die beiden Deckschichten 122, 124 mit der tragenden Schicht 129 verklebt oder mittels Walzplattieren verbunden sein. Da sich die beiden Verkleidungsbauteile 28/77 und 23/74 mit ihren aus korrosionsbeständigem Stahl gefertigten Deckschichten 114, 122 im Bereich der Senkkopfschraube 103 berühren, ist auch hier bezüglich der elektrochemischen Spannungsreihe kein Potentialunterschied vorhanden. Vorzugsweise ist auch die Senkkopfschraube 103 aus korrosionsbeständigem Stahl gefertigt.The
Da beide Verkleidungsbauteile 28/77, 23/74 mittels einer Senkkopfschraube 103 an der Aufnahmeplatte 101 befestigt sind, weisen beide einen dieser Senkkopfschraube 103 zugeordneten Durchbruch 115, 125 auf. Der Durchbruch 125 des als Abdeckung dienenden Verkleidungsbauteils 28/77 weist eine durch Prägen kegelförmig ausgestaltete Ausformung auf, welche den Kopf der Senkkopfschraube 103 aufnimmt, so dass dieser nicht vorsteht. Die Schnittkanten 116, 126 beider Durchbrüche 115, 125 werden durch die jeweilige Deckschicht 114, 124 abgedeckt. Deshalb ist auch der Durchbruch 115 des als Seitenwand dienenden Verkleidungsbauteils 23/74 konisch ausgebildet. Auch die Schnittkanten 117, 127 an den Randbereichen der Verkleidungsbauteile 28/77, 23/74 sind jeweils durch die gegen die Umgebung gerichtete Deckschicht 114, 124 abgedeckt. Nachfolgend werden zwei Beispiele beschrieben, wie durch die Deckschicht abgedeckte Schnittkanten erzeugt werden können.Since both

Um eine optimale Abdeckung der Schnittkante 117 zu erzeugen, muss die Fasenhöhe P und deren Fasenwinkel β auf die Materialeigenschaften des zu schneidenden Verbundstahlbleches 110 und den Scherwinkel α abgestimmt werden, wobei die idealen Werte mittels Versuche empirisch ermittelt werden können. Dabei kann der Scherwinkel α zwischen 0° bis 30°, der Fasenwinkel β zwischen -90° bis 15° und die Fasenhöhe P zwischen 0 und 2mm gewählt werden. Vorzugsweise ist der Scherwinkel α zwischen 5° bis 20°, der Fasenwinkel β zwischen -85° bis -60° und die Fasenhöhe P zwischen 0.5mm und 1.0mm. Ausgehend von der zur Seitenfläche 113 orthogonal stehenden Vertikalen V beziehungsweise Lotrechten V, sind die Winkelwerte im Uhrzeigersinn mit positiven, die Winkelwerte im Gegenuhrzeigersinn mit negativem Vorzeichen angegeben.In order to produce an optimum coverage of the

Wenn sich die Fasenkante 144 und die Schneidekante 146 treffen, wird auch die durch das Ziehen in diesem Bereich wesentlich dünner gewordene Deckschicht 114 durchtrennt, wie dies in der
Selbstverständlich können die Konturen der aus Verbundstahlblech 110 bestehenden Teile eines Verkleidungsbauteils 23/74 auch durch Wasserstrahlschneiden oder durch Laserschneiden herausgearbeitet werden. Wenn die derart bearbeiteten Schnittkanten 117 ebenfalls durch die Deckschicht 114 überdeckt sein sollen, kann die Deckschicht 114 beispielsweise mittels eines Walzwerkzeuges über die Schnittkante 117 gewalzt oder mittels eines Presswerkzeuges über die Schnittkante 117 gepresst oder gezogen werden. Die Schnittkante 117 kann aber auch mit einem selbstklebenden Dichtstreifen oder einer flüssig aufgetragenen, aushärtenden Polymerschicht flüssigkeitsdicht abgedeckt werden. Dasselbe gilt natürlich auch für die Schnittkanten 127 des Verkleidungsbauteils 28/77.Of course, the contours of existing from

Um den Durchbruch 125 zu erzeugen, weist das Werkzeug einen Stanzstempel 150, einen Prägestempel 151 und eine Gesenk- Matrize 152 auf. Das Verbundstahlblech 120 des Verkleidungsbauteils 28/77 wird auf die Gesenk- Matrize 152 gelegt und ausgerichtet. Anschließend wird wie in der

Je nach den Materialeigenschaften der verwendeten Polymerschicht kann diese beim Prägestanzen im Bereich der umgeformten Schnittkante 126 brechen oder einreißen. Um ein Eindringen von Feuchtigkeit zwischen die tragende Schicht 129 und die Deckschicht 124, 122 zu verhindern, kann beispielsweise bei der Montage der Schraube diese Stelle mittels einer Silikondichtmasse versiegelt werden.Depending on the material properties of the polymer layer used, it may break or tear during stamping in the region of the formed
Obwohl die Erfindung detailliert anhand zweier Verkleidungsbauteile des Eckbereichs eines Balustradensockels beschrieben worden ist, ist es offensichtlich, dass alle anderen Verkleidungsbauteile einer Fahrtreppe oder eines Fahrsteiges in gleicher Weise ausgeführt werden können. Selbstverständlich müssen nicht alle Verkleidungsbauteile aus Verbundstahlblech 40, 110, 120 gefertigt sein. So können beispielsweise die in der
