Definitions

  • the present invention relates to elevator car floors in composite structure, also sandwich construction called in cabins of passenger or Cargo lifts are used.
  • Such cabins are Usually installed in so-called cabin frames, the in turn led to mounted in lift shafts rails and moved by drive machines via wire ropes up and down become.
  • An elevator cabin floor usually has the function that Weight of the cabin superstructure with walls, canopy, Cabin doors and various fittings as well as the entire maximum payload and, most of the time via suitable Vibration isolation elements, in the cabin frame initiate. It is important that the entire floor is even under eccentric load does not exceed certain limits deformed, that means bent or twisted. As well important is that he is not affected by spurious vibrations like them mainly from the drive via the suspension cables to the cab be transferred to impermissibly strong intrinsic bending vibrations can be stimulated. This will be on safest due to high bending stiffness of the soil in all Directions resulting in the highest possible bending natural frequency reached.
  • EP 0 566 424 B1 describes an embodiment of an elevator cabin floor in which the required properties are to be achieved by using a composite structure principle (sandwich principle).
  • a core made of wood, cardboard or thermoplastic foam is glued in substantially between an upper cover plate designed as a composite layer and a similar lower base plate.
  • cover plate which forms the cabin floor surface, against concentrated to small areas loads; are inserted between strips of the core material supporting webs. So that subsequent cabin parts, such as, for example, cabin walls or door sleepers can be fixed to this floor, the described composite structural panel is enclosed by a steel frame.
  • EP 0 700 860 A1 also discloses one in the form of a composite structure built elevator cabin floor in which on one Base plate acting as a pressure sensor layer, an elastic Intermediate layer and a floor layer are constructed.
  • the base plate as well as the floor layer form one each independent composite structure, consisting of one each Core layer and two outer layers.
  • core layers are so-called honeycomb structures used.
  • Honeycomb structures consist of a multiplicity of mutually parallel, upright thin metal or plastic strips, the so deformed and at defined intervals laterally with each other are glued that they have a honeycomb-shaped core Form cavities. This core is in each case between two outer layers glued in, taking the distance between them determined and by transmission of shear stresses between the Outer layers the required flexural rigidity of the composite structure guaranteed.
  • the present invention is an elevator car floor construction according to claim 1, based on the composite structure or sandwich construction, which meets all the requirements listed above for an elevator car floor in an ideal manner.
  • the construction consists essentially of a base and a cover plate of tensile and pressure-resistant material with the highest possible modulus of elasticity, as well as an intermediate composite structure core, which, in contrast to previously known versions of wood, foam, etc., from a kind Grating exists.
  • This is composed of a plurality of perpendicular intersecting upstanding lamellae, each of which run a number parallel to the longitudinal and the transverse edge of the floor with mutually equal distances and which are connected at their intersection points respectively with the base and the cover plate.
  • the length and width of this grate core correspond to the dimensions of the cabin floor.
  • a cabin floor optimized according to this principle exhibits optimum rigidity in all directions, given a given material specification and given limits in terms of installation height and weight, combined with a maximum possible bending natural frequency.
  • the all-round support of the cover plate along the square panels of the grid also gives it the important ability to absorb high loads concentrated on small areas without permanent deformation.
  • the base and the cover plate as well as the Slats of the wire grid core made of sheet steel, on the one hand the strength-technical requirement for a material with high elastic modulus and minimum creep, and on the other hand, the construction is all relevant Fire protection requirements.
  • a significant advantage is also that in this way the entire ground with conventional Metal processing technology can be produced.
  • the required mutual connection of the composite structure components is carried out in a suitable manner so that the grating louvers are welded at their intersection points by means of "hole welding" with the cover and the base plate, which are referred to below as the cover and base plate.
  • This welding takes place from the outside of the two sheets forth by pre-punched holes whose position coincides with the crossing points of the grating louvers.
  • the mutual multiple crossover of the right angles mutually extending slats of the grating is characterized allows the slats at all crossing points with at right angles to their longitudinal axis punched slots are provided whose width of the slat material thickness corresponds, and in the longitudinal slats of above and at the transverse from below each to the reach half slat height.
  • This can be the transverse lamellae at all points of intersection so in insert the longitudinal ones that all the slats open same level and the above described Form grid.
  • the side walls of the cabin floor are made by bending the according to pre-cut cover sheet produced what the Manufacturing process simplified.
  • Another advantage of the inventive construction is that the mentioned side walls of the cabin floor with the ends of the slats of the grate core through Welding are rigidly connected, causing a high strong, rigid mounting option for components such as Threshold, door frame and cabin walls on these side walls results.
  • Fig. 1 shows a preferred embodiment of the inventive elevator cabin floor.
  • the floor is made entirely of sheet steel by means of bending and welding. It consists essentially of the cover plate 1 with gebogenem door sill support 6, the base plate 2 and the lying between the cover and base plate grate core 3 of intersecting longitudinal and transverse lamellae 4.5. Also visible are components that fulfill lift-specific functions, such as the side wall profiles 7, stiffeners 8 for the door sill support and support sections 13 with fastening threads for serving as a connection between the cabin floor and cabin frame insulation elements (not visible). In the area of Fig. 1, where the base plate 2 is shown as partially removed, you can see the construction of the grate core 3. This is shown in more detail in Fig.
  • the cross blades 5 in the longitudinal slats 4 are inserted.
  • the thickness of the lamellae of the lattice core and their mutual distances are variable depending on soil load, cover plate thickness and overall height and are optimized by means of FEM calculations.
  • slot-shaped holes 9 the position of each coincides with a crossing point of the slats of the grate core.
  • Corresponding holes are also present in the cover plate. Through these holes 9, as shown in Figure 3, by means of hole welding, the cover plate 1 and the base plate 2 with the grate core 3 rigidly connected.
