Definitions

  • the invention relates to a supporting structure for escalators and moving walks, which essentially consist of two sideways one Step or plate conveyor line arranged, mainly in Longitudinal and vertical direction, with each other Crossmember connected wall beams and constructive Adaptations for use with large spans.
  • Such vibrations can by periodic impulses from the drive or the revolving stage conveyor line, but also by moving Passengers are excited.
  • Annoying or even dangerous large bending or torsional vibrations are the easiest by executing the supporting structure with high Stiffness and low mass, that means with corresponding high natural frequencies can be avoided.
  • Usual supporting structures for escalators and moving walks consist essentially of a step or on both sides Plate conveyor line arranged, with each other via cross beams connected, mainly in the longitudinal and vertical directions oriented so-called wall supports. These are mostly in Half-timbered construction made from rolled profiles or rectangular tubes, but can also by other methods such. B. in Solid wall or sandwich construction. Standardized wall brackets are for reasons of cost optimization designed so that the stability of them manufactured support structures for the majority of all occurring bridging distances is sufficient. For the remaining versions with larger bridging distances usually complex special solutions are to be used, such as supporting structures with wall supports of greater height, supporting structures made of thicker profiles or supporting structures with stiffening Additional structures.
  • a supporting structure according to the preamble of Claim 1 is known from US-A-4,674,615.
  • the present invention is based on the object Increase required for long escalators and moving walks of bending and torsional rigidity of the supporting structure little effort for manufacturing and logistics and under To avoid the disadvantages described above.
  • both basic wall supports of the supporting structure each have at least one additional, usually identical additional wall bracket is flanged.
  • the solution according to the invention has significant advantages over those in which the geometry or the construction materials of the wall supports are each to be adapted to the bridging lengths or special constructions are to be used. All wall brackets can be manufactured using the same normalized method from identical raw materials with the same machine settings and gauges. Raw materials and processing tools are only to be kept in stock for this version. For series production, only stocks of prefabricated wall brackets of one type are required. The aesthetic appearance of the escalators and moving walks is not impaired by increased height or by visible additional structures.
  • An advantage of the reinforcement principle described is that it for a wide variety of wall bracket designs, z. B. for wall brackets in truss, full panel, bending profile or Composite panel construction is applicable.
  • Fig. 1 is a usual rising moving walk 1 in side view shown, with two vertical arrows Mark the position of its support 2 through the building and point out that the intermediate zone of the supporting structure of the moving walk as a free bending beam is.
  • Fig. 2 shows the support structure 3 of a moving walk in Half-timbered construction, which essentially consists of two by means of cross beams connected wall supports. Is shown here already the embodiment according to the invention with double wall supports. Length-related separations in are not visible the tension and compression straps 12, 13 of the wall beams, because of limited raw material lengths as well as from manufacturing or assembly reasons are unavoidable.
  • the angle profile belts 12, 13 are welded at the separation points Provide flanges over which the wall brackets during assembly can be assembled using screw connections.
  • Fig. 3 shows a cross section through a moving walk, wherein the left half of the cross section the standard version of the Supporting structure with basic wall brackets 4 and the right one Half with an additional wall bracket 5 according to the invention represent reinforced execution.
  • Fig. 4 shows an enlarged cross section through a Double wall bracket, which is flanged to one side Additional wall bracket (5) to a base wall bracket (4) is.
  • Wall trusses in half-timbered construction are shown, consisting of upper angle profile tension belts 12, lower Angle profile pressure belts 13 and the ones welded to them Truss struts 14. It is clear from Fig. 4 that like a double wall bracket by flanging them together two identical but mirror-image wall brackets arises, with the base wall bracket on one side the supporting structure is identical to the additional wall bracket on the other hand.
  • the connection between basic and Additional wall supports are made by screwing 15, can but also be carried out by means of rivets or welding.
  • Sectional view V-V (Fig. 5) shows one of these connections as a screw connection 15 in the area of the truss struts 14, with an intermediate piece 16 inserted between the struts is.
  • Similar wall brackets can also be made from rectangular hollow profiles. They are suitable as basic and additional wall brackets and enable their identical, symmetrical structure for left and right versions.
  • Fig. 6 shows an embodiment of wall supports which are constructed from rectangular hollow profiles 17 in a framework arrangement. At their length-related separating points, the wall support sections have intermediate flanges 18 which are braced against one another during assembly by means of screw connections 19.
  • FIG. 7 shows how, in the case of wall supports made of rectangular hollow profiles 17, the additional wall supports with screw connections 20 are flanged to the side of the base wall supports in the area of the connecting flanges 18.
  • FIG. 8 shows a further possible embodiment of double wall supports, in which case the additional wall support 21 consists of solid steel plates. Where necessary, these are provided with through openings 22 and connected to the base wall bracket by screws.
  • FIG. 9 shows how the additional wall bracket 21 is assembled at length-related separating points via welded-on angle flanges 23 by means of screw connections 24.
