Definitions

  • the present invention relates to elevator car floors in composite structure, also sandwich construction called that in cabins of people or Freight lifts are used.
  • Such cabins are usually installed in so-called cabin frames, the in turn guided on rails fastened in lift shafts and moved up and down by drive machines via wire ropes become.
  • An elevator car floor normally has the function of absorbing the weight of the cabin superstructure with walls, cabin roof, cabin doors and various internals, as well as the entire maximum payload, and introducing it into the cabin frame, usually via suitable vibration isolation elements. It is important that the entire floor is not deformed beyond certain limits even under eccentric load, that is, it bends or twists. It is just as important that it cannot be stimulated to impermissibly strong self-bending vibrations by disturbing vibrations, as they are mainly transmitted from the drive to the cabin via the suspension cables. The safest way to achieve this is through the high bending stiffness of the floor in all directions, resulting in the highest possible natural bending frequency.
  • a cabin floor Another requirement of such a cabin floor is that its surface, which is usually formed by a steel sheet, undergoes permanent deformations under high loads concentrated on small areas (for example by means of transport with relatively small wheels).
  • a cabin floor should have the lowest possible mass and a minimal overall height.
  • the regulations of certain European countries also stipulate that elevator cars may only contain minimal amounts of materials that are not considered non-flammable "are classified.
  • EP 0 566 424 B1 describes an embodiment of an elevator car floor in which the required properties are to be achieved by using a composite structure principle (sandwich principle). Essentially, a core made of wood, cardboard or thermoplastic foam is glued between an upper cover plate designed as a composite layer and a similar lower base plate. In order to achieve sufficient resistance of the cover plate, which forms the cabin floor area, against loads concentrated on small areas, support webs are inserted between strips of the core material.
  • the present invention relates to an elevator car floor construction according to claim 1, based on the composite structure or sandwich construction, which ideally fulfills all of the above requirements for an elevator car floor.
  • the construction essentially consists of a base plate and a cover plate made of tensile and compressive material with the highest possible modulus of elasticity, as well as an intermediate composite structure core, which, in contrast to previously known designs made of wood, foam, etc., consists of one type
  • a grating This is made up of a large number of perpendicularly intersecting, vertical slats, of which a number run parallel to the longitudinal and transverse edges of the floor at equal distances from one another and which are connected to the base and cover plates at their crossing points.
  • this grating core corresponds to the dimensions of the cabin floor.
  • a cabin floor manufactured according to this principle and optimized with the help of FEM calculations, with given material specification and given limits with regard to installation height and weight, has optimal rigidity in all directions, combined with the highest possible natural bending frequency.
  • the all-round support of the cover plate along the square fields of the grating also gives it the important ability to absorb high loads concentrated on small areas without permanent deformation.
  • the base and cover plate as well as the Slats of the grating core made of sheet steel, on the one hand the strength requirement for a material high modulus of elasticity and minimal creep, and on the other hand the construction corresponds to all relevant ones Fire protection requirements.
  • Another major advantage is that in this way the entire floor with conventional Metal processing technology can be produced.
  • the mutual multiple crossing of the right angle mutually extending slats of the grating is thereby allows the slats to cross at all intersections slots punched at right angles to their longitudinal axis are provided, the width of the slat material thickness corresponds, and that in the longitudinal slats of above and in the case of the transverse ones from below to half the height of the slats is sufficient.
  • This allows the transverse slats at all crossing points in such a way insert the longitudinal ones that all the slats on come to the same level and those described above Form grating.
  • the side walls of the cabin floor are made by bending the generated according to pre-cut cover plate, which the Manufacturing process simplified.
  • Another advantage of the construction according to the invention is that the mentioned side walls of the cabin floor with the ends of the slats in the grating core Welding is rigidly connected, causing a high resilient, rigid mounting option for components such as Door threshold, door frame and cabin walls on these side walls results.
  • the floor is made entirely of sheet steel by means of bending and welding. It essentially consists of the cover plate 1 with a bent door sill support 6, the base plate 2 and the grating core 3 between the cover plate and base plate, consisting of intersecting longitudinal and transverse slats 4, 5. Components that perform lift-specific functions, such as the side wall profiles 7, stiffeners 8 for the door sill support and support profiles 13 with fastening threads for the insulation elements serving as a connection between the cabin floor and the cabin frame (not visible) are also visible. In the area of FIG. 1, where the base plate 2 is shown as partially removed, the construction of the grating core 3 can be seen. This is shown in more detail in FIG.
  • the transverse slats 5 into the longitudinal slats 4 can be inserted.
  • the thickness of the lamellas of the grating core and their mutual spacing are variable depending on the floor load, cover plate thickness and overall height and are optimized using FEM calculations.
  • punched, slit-shaped holes 9 can be seen, the position of which corresponds to a point of intersection of the slats of the grating core.
  • Corresponding holes are also available in the cover plate. Through these holes 9, as shown in FIG. 3, the cover plate 1 and the base plate 2 are rigidly connected to the grating core 3 by means of hole welding. In principle, welding processes (e.g.
  • Fig. 1 it can also be seen that the ends of the lamellae 4.5 of the grating core extend to the side walls (for example at 10) and to the stiffeners of the door sill support 6, where they are welded to them and give them enormous rigidity, what is of great importance for their function as supports for walls and thresholds.
  • the lamellae 4, 5 contain openings 11 at half their height at each intersection, which ensures that, when dip-painting, the coating liquid can penetrate into all cavities of the cabin floor suspended at a corner and flow out again.
