Definitions

  • the invention relates to a folding staircase with a cantilevered head side and a plurality of treads, wherein between two successive treads a riser is arranged.
  • the invention relates to a profile step for a folding staircase, wherein the profile step comprises a tread and a riser associated therewith.
  • folding staircases form the treads and usually perpendicular thereto risers also a visually uniform structure, which receives a male load, such as one or more users of the folding staircase, and distributed over the entire construction.
  • a male load such as one or more users of the folding staircase
  • the greatest load in the area of a loaded tread and the associated risers is mainly due to bending stresses. These must be withstood by the folding staircase without damaging the steps and thus the entire folding staircase.
  • Faltwerktreppen the above type are generally not completely free, but are on a long side, so a mounting side, anchored to a wall. There are Faltwerktreppen, which are also held on the opposite side of the mounting side of the head, for example on the handrail on a support frame or on a ceiling.
  • folding staircase of the type mentioned are on the cantilevered head side no additional bracing and / or support or Scaffolding elements provided.
  • self-supporting folding staircase used below includes self-supporting folding staircases on both sides as well as folding staircases in which only one side, for example the head side facing away from the wall, is cantilevered.
  • a self-supporting folding staircase looks all the more elegant, the thinner the individual treads and risers are formed. However, since a folding staircase must meet certain load criteria, the possible smallest thickness of the treads or risers depends on the material of the same. If you want to achieve a particularly slim appearance of self-supporting folding staircase, the treads and risers should not exceed a thickness of about 4.0 cm. Apart from steel as a step material cantilever Falttechniktreppen are not feasible with such thin treads or risers in currently used materials, such as stone or wood, as a built-up self-supporting Falttechniktreppe the required capacity is not enough.
  • treads and / or the risers are each formed as a layer composite plate, which comprises at least two cover plates and an intermediate layer arranged therebetween.
  • the layer composite plates and thus the treads and / or the risers can be made thinner overall than was previously possible with a material other than steel.
  • At least one tread and / or at least one riser has a thickness of about 4.0 cm. This achieves the desired slim appearance of the folding staircase.
  • cover plates of at least one tread and / or at least one riser have a thickness of about 2.0 cm. In this way, the load distribution takes place evenly within the respective stage. In composite laminates, this is referred to as 2 + 2 plates.
  • the intermediate layer of at least one tread and / or at least one riser is an adhesive layer connecting the cover panels.
  • the desire for a folding staircase made of a high quality and high quality material is taken into account, if the cover plates of the support levels and / or the risers are made of a granite stone.
  • the intermediate layer is a two-component adhesive based on epoxy resin. In this way, a resilient granite block composite plate is formed.
  • the cover plates of the support structures and / or risers may be formed of marble or limestone.
  • the intermediate layer is a polyester resin-based two-component adhesive, whereby a load-bearing marble or limestone layer composite plate is accordingly formed.
  • a good connection between two successive treads and an intermediate riser is achieved when an adhesive layer is provided between each of them.
  • a two-component adhesive based on epoxy resin or polyester resin in question is advantageous.
  • the stability of the folding staircase and the load distribution within the same it is beneficial if at at least one tensioning device is provided in the folding staircase, which connects in each case two successive steps with the riser arranged therebetween.
  • the stability is further increased and the load distribution is improved when a first bracing device and a second bracing device are provided for each two successive treads and the riser arranged therebetween, wherein the first bracing device on the cantilevered head side and the second bracing device on the opposite side of Faltwerktreppe is provided.
  • the tread and / or the riser is formed as a layer composite plate, which comprises at least two cover plates and an intermediate layer arranged therebetween.
  • a structurally large folding staircase can be delivered in individual modules, each module is formed by a corresponding profile level.
