Definitions

  • the invention generally relates to an escalator or moving walk with a soffit sheet.
  • the invention particularly relates to the attachment of the soffit sheet to a supporting structure of the escalator or moving walk.
  • 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 stepped belt or a pallet band, deflection axes, a drive shaft and the drive motor with gearbox, its control, monitoring systems, security systems and the like.
  • fixed components such as balustrades, comb plates, bearings, raceways and guide rails are firmly connected to the structure.
  • US 4 175 653 describes an escalator, which includes a support structure formed by carriers. On the lower chords of the structure, a soffit plate is welded. The welds of this soffit sheet are formed circumferentially so that an oil-tight well formed by the bottom sheet and the bottom chords is present. The bottom sheet contributes substantially to the rigidity of the structure, in particular, the torsional rigidity is increased.
  • the underside panel must have a wall thickness of 3 mm to 5 mm for the given large areas of the underside of an escalator or a moving walk, so that it does not begin to vibrate due to the operational vibrations and a membrane produces the same, unpleasant noise.
  • the weld should be circumferential, so that the bottom sheet does not sag. Structures with a welded soffit are therefore heavy and their manufacture expensive. Furthermore, due to the high transport weight also high transport costs.
  • Object of the present invention is therefore to an escalator or a moving walk create, whose structure is cheaper to produce with a soffit and whose sound-absorbing properties are equal to or better than those of a conventionally manufactured structure of the same dimension.
  • an escalator or a moving walkway which has a supporting structure and a flat sheet which is limited in its areal extent by side edge areas.
  • a first side edge region of the soffit plate is firmly connected to the structure.
  • the soffit sheet is further biased with a predetermined biasing force value between the first side edge portion and a second side edge portion opposite the first side edge portion. To maintain the bias and the second side edge area is firmly connected to the structure.
  • Preservation of the prestressing force increases the rigidity of the structure and reduces noise during operation of the escalator or moving walkway.
  • the first and the second side edge region of the soffit plate can be firmly connected to the supporting structure in a non-positive, cohesive or form-fitting manner.
  • Welded connections and soldered connections are suitable as cohesive, firm connections.
  • frictional, firm connections are terminal strips and fittings.
  • As a positive, firm connections rivets, clinching, clinching, and fittings are combined with pin connections.
  • a vibration spectrum with low frequencies for example, from 4 hertz to 15 hertz.
  • This vibration spectrum can be in the range of the resonant frequency of an untensioned underside panel and thereby lead to an unpleasant noise during operation.
  • the manufacturing cost is reduced enormously compared to a weld seam surrounding the soffit plate.
  • the first side edge portion and the second side edge portion are fixedly connected to the supporting structure, while the third side edge portion and the fourth side edge portion are not fixedly connected to the supporting structure.
  • a vibration-damping intermediate layer may be arranged at least in sections.
  • the at least sectionally arranged vibration-damping intermediate layer in the side edge regions of the prestressed soffit plate prevents the generation of noise by vibrations in the low and medium frequency range.
  • vibrations with medium frequencies can lead to temporary local lifting off of the remaining, not firmly connected side wall areas from the supporting structure and generate noises during the rebound to a lower flange of the structure.
  • the structure may be subdivided into structural modules, each of these Structural modules has a soffit plate. Its first side edge region and its second side edge region opposite the first side edge region are firmly connected to the supporting structure. The soffit sheet of each structural module is biased between the first side edge region and the second side edge region.
  • a vibration-damping intermediate layer can also be arranged at least in sections between the remaining side edge regions and the supporting structure module in the individual structural modules.
  • the vibration-damping intermediate layer can be arranged on lower straps of the side parts and on the lower straps adjoining transverse struts.
  • the cross struts may be, for example, cross members, transverse bridges, transverse slabs, transverse angle cross-sectional profiles and the like.
  • the vibration-damping intermediate layer can be, for example, a polymer material tape or polymer material adhesive tape.
  • An adhesive, applied at least in sections, can also be used as a vibration-damping intermediate layer.
  • the adhesive is an oil-resistant adhesive sealant applied circumferentially around the entire side edge region, an oil-tight or liquid-tight and dust-tight trough can be formed with the bottom sheet and with parts of the structure or structural module.
  • Particularly suitable are pasty or liquid one-component adhesives / sealants based on silane-modified polymers which crosslink by atmospheric moisture to form an elastic product. These are used, for example, in body and vehicle construction, wagon construction and container construction and in metal and apparatus engineering.
  • the lower chords of the structure are stressed in the operating position of the escalator or moving walk by tensile forces, while the upper chords need to absorb pressure forces.
  • the bias of the soffit plate relieves the lower chords as the biasing force in the lower chords causes compressive forces.
  • the upper straps are relieved, as the tension causes tensile forces in the upper straps.
  • the cross-section of the soffit sheet must be dimensioned accordingly for a given allowable yield strength of the material, so that this both the Preload force as well as a part that can absorb the load-bearing capacity and net mass caused by the structure to tensile force in the lower flange of the structure.
  • the material of the structure preferably differs from the material of the soffit sheet in its material properties, wherein the soffit sheet preferably has a higher yield strength than the material of the structure.
  • the soffit sheet preferably has a higher yield strength than the material of the structure.
  • the bottom panel has a thickness of 0.8 mm to 1.0 mm. Tests have shown that soffits of this thickness can be easily clamped over obtuse corners of the structure or structural module.
  • the butt joint is preferably arranged in the region of a transverse strut.
  • the bottom sheet is biased in the longitudinal extent of the structure or structural module. This has the advantage that the lower chords and upper chords of the structure as described above, can be relieved.
  • the structure or structural module may be provided with reinforcing means for receiving the bias.
  • Such reinforcing means may be reinforcing ribs, reinforcing plates, reinforcing profiles or reinforcing struts which are integral with and remain with the structural or structural module.
  • structural modules can also have temporary reinforcing means, which are connected only during the manufacturing process with the structural module and can be removed after assembly of the structure.
  • the soffits can have any shape in their areal extent.
  • the first margin area and the second margin area must also not be arranged parallel to each other.
  • the bottom sheet is preferably formed square or rectangular.
  • the method for covering a structure or structural module of an escalator or a moving walkway with a bounded by side edge areas of the soffit plate is extremely inexpensive and easy to carry out and involves only a few steps.
  • a vibration-damping intermediate layer may be arranged at least in sections. This can be done before connecting the first side edge area to the structure or
  • the vibration-damping intermediate layer can also be arranged after connecting the first side edge region to the supporting structure or structural module.
  • the supporting structure or structural module is usually brought into a production position, so that the surface to be covered is directed upwards. In the operating position, the surface covered with the soffit sheet is directed downwards.
  • the biasing of the soffit plate can be done with a clamping device having at least one hydraulic unit, a compressed air connection, and at least one hydraulic cylinder or pneumatic cylinder.
  • the preload force can be very by the oil pressure in the hydraulic cylinder or gas pressure in the pneumatic cylinder set well and check.
  • the pretensioning can also take place with a tensioning device which has at least one threaded spindle.
  • a tensioning device which has at least one threaded spindle.
  • a combination of threaded spindle and hydraulic cylinder or pneumatic cylinder is possible, wherein the pneumatic or hydraulic cylinder is used to apply the clamping force and the threaded spindle to secure the tensioned state, until the second side edge region is firmly connected to the structure. Subsequently, the clamping device can be removed.
  • top sheets of the aforementioned thickness of 0.5 mm to 2.5 mm and 1.5 m wide can be prestressed with a clamping force of 10 kN to 140 kN and excellent flatness can be achieved.
  • Corresponding tests were successfully carried out on structures with widths of 0.9 m, 1.1 m, 1.3 m, 1.7 m, 1.9 m, and 2.1 m.
  • Particularly good results have been obtained with stainless steel soffits, for example 1.4301 (X5CrNi18-10), which have been pretensioned at 1.5 m width and 0.8 mm thickness at 35 kN to 55 kN.
  • FIG. 1 shows an escalator 1 with a handrail 2.1 supporting balustrade 2. Furthermore, the escalator 1, a supporting structure 5, which carries the balustrades 2. The balustrades 2 have base plates 3, between which laterally guided steps 4 are arranged circumferentially.

  • the structure 5 is divided into a first structural module 5.1, in a second structural module 5.2 and in a third structural module 5.3.
  • This subdivision is particularly advantageous in structures 5 of very far spanning escalators and moving walks, as they can be easily transported from the factory to the installation. Even cramped installation conditions in existing buildings may require subdivision.
