Definitions

  • the invention relates to a connecting support for a carrier of an escalator or a moving walk, wherein the connecting support comprises a flat steel and at least one connecting hole.
  • Girders of an escalator or a moving walk are manufactured in individual segments, which are connected to one another by means of connecting supports to form a complete girder.
  • the connecting supports are exposed to very high loads, in particular in a central region of the assembled girder. Accordingly, the connecting supports must have a very high level of stability.
  • the connecting supports have been manufactured using a flame cutting process.
  • this method has the disadvantage that the connecting supports then have to be reworked by machine in order to remove an edge layer hardening by the flame cutting and to enable them to be welded into the carrier.
  • a connecting support produced by means of a flame cutting process a simple flat steel can also be used as a connecting support. This has the advantage that a flame cutting process and subsequent machine post-processing are no longer necessary. The manufacturing process of the connecting support is thus significantly simplified.
  • the disadvantage is that when flat steel is used, the material thickness of the connecting support has to be increased significantly so that the connecting support can withstand the loads to which it is exposed after the escalator / moving walk has been completed.
  • the material thickness has to be increased from around 30mm to around 50mm.
  • the costs for drilling connecting holes in the connecting support increase, since high-speed tools cannot be used due to the greater material thickness.
  • the object of the present invention is accordingly to provide a solution for a connecting support, with the material and costs for the manufacturing process being significantly reduced.
  • the proposed solution provides a connecting support for a support of an escalator or a moving walk, the connecting support having a flat steel and at least one connecting hole.
  • the connecting support has at least one removable reinforced area.
  • the connecting support comprises a flat steel with a small material thickness.
  • the material thickness is 30mm.
  • the connecting support is locally reinforced by a removable reinforced area.
  • the connecting support can be individually reinforced by means of the removable reinforced area.
  • the connecting support has at least one press plate.
  • the removable reinforced area of the connecting support has at least one press plate.
  • the connecting support is reinforced by means of the at least one press plate.
  • the connecting support is individually reinforced by a material thickness of the at least one press plate. In particular, the material thickness of the at least one press plate is 20-30mm.
  • At least one press plate is arranged on the flat steel by means of releasable fastening means.
  • the at least one press plate can be exchanged by means of the releasable fastening means.
  • the reinforcement of the connecting support can thus be adapted individually.
  • the reinforcement of the connecting support can thus be readjusted.
  • the at least one press plate is arranged on the flat steel in such a way that a material thickness of the connecting support is locally increased by means of the press plate.
  • the connecting support according to the invention has the advantage that there is no need for a flame cutting process and thus a corresponding reworking of the connecting support, which leads to lower production costs. Nevertheless, the connecting support according to the invention has a material thickness similar to that of a connecting support produced by means of a flame cutting process. In particular, the flat steel of the connecting support according to the invention has a material thickness of 30 mm. The low material thickness means that less steel is required, which leads to a significant reduction in manufacturing costs.
  • the connecting support can be individually reinforced according to the requirements by adjusting the material thickness of the pressing plates.
  • a connecting support without pressure plates withstands a force of 100 kN.
  • a connecting support with press plates with a material thickness of 30mm withstands a force of 180kN.
  • Fig. 1 shows a known connecting support 100 for an escalator or a moving walkway.
  • the connecting support 100 shown is produced by means of a flame cutting process.
  • the connecting support 100 is designed in two layers in the exemplary embodiment shown, the two layers of the connecting support 100 being connected to one another by means of detachable fastening means 102, in particular a screw connection.
  • the connecting support 100 has connecting holes 101 for fastening individual components of the escalator / moving walk.
  • the connecting support 100 has a reinforced area 103 in the form of a projection. In order to ensure the necessary stability of the connecting support 100, additional material is therefore necessary, which leads to additional material costs.
  • Connecting support 100 produced by means of a flame cutting process has the disadvantage that the edge layers of the flame cutting harden during flame cutting. This hardening must be removed by milling off the surface in order to ensure that it is suitable for welding. This post-processing prevents a renewed hardening of the material due to the local heating during welding of the connecting support into the carrier, which can cause the material to become brittle, which can lead to cracks in the material.
  • a connecting support 100 consisting essentially of a flat steel 104 can be used, as in FIG Fig. 2 shown.
  • the flat steel 104 In order to meet the necessary stability requirements, however, it is necessary for the flat steel 104 to have a certain material thickness. In order to provide the necessary stability, it is essential that the material thickness of the connecting support 100 increases overall.
  • the flat steel 104 of the in Fig. 2 shown connecting support 100 have a material thickness of about 50mm. This leads to increased material costs.
  • Fig. 3 shows the connecting support 100 according to the invention.
  • the connecting support 100 according to the invention is a further development of the in Fig. 2 connecting support 100 shown, wherein the material thickness of the flat steel 104 used with respect to the in Fig. 2 connecting support 100 shown is significantly reduced.
  • the connecting support 100 shown has a removable reinforced area 103.
  • the removable reinforced area 103 is formed by at least one press plate 105 which is arranged on the flat steel 104 of the connecting support 100 by means of releasable fastening means 102.
  • the material thickness of the connecting support 100 is increased locally by means of the pressing plate 105, as a result of which the stability and thus the load capacity of the connecting support is increased.
  • connection support 100 has the advantage that the material thickness of the connection support 100 can be locally increased individually by means of the pressure plate 105 by attaching a pressure plate 105 of a corresponding thickness and can thus be individually adapted to the stability requirements.
  • connecting support 100 without reinforcement by arranging the at least one press plate 105 if the stability requirements of individual connecting supports 100 in a girder of an escalator / moving walk are low.
