Definitions

  • the invention relates to a staircase, which is suitable, for example, for use in the construction of buildings or for industrial use and thus relatively quickly assembled and disassembled.
  • staircases which include several individual treads, which are laterally interconnected by fittings. Such a staircase can be pulled apart like a concertina for proper use as a staircase and folded to save space for transport and storage. During assembly, the staircase is pulled in the extended state of squared timbers, which then form the two side walls for the staircase and where the treads can be fixed.
  • Such a staircase with squared timbers can be mounted quickly and easily, but due to their heavy weight, it is difficult and in particular not manageable by a single person.
  • the invention has for its object to provide a staircase that is easy to handle and preferably montierund dismantled by a single person, and ensures reliable protection against lifting of the stair elements.
  • a scaffolding staircase with the features of claim 1.
  • a lift-off for the respective step element can be achieved.
  • the step element can be moved into an end position by turning or pivoting, in which the projection engages in the recess or the opening.
  • no further components such as screws and nuts for the formation of the coupling connection between the step elements and side walls are needed solved.
  • An item that naturally has a significantly lower weight than the entire scaffold staircase can be transported or carried individually, and in particular by a single person.
  • the scaffolding stairs according to the invention is particularly easy to handle and can, especially at different locations, quickly and easily up and dismantled by a single person.
  • middle staircase elements ie staircase elements, which are arranged with mounted scaffolding staircase between a lowermost and a top step element, coupled both with the immediately below and the step element arranged directly above, so that a particularly stable and reliable scaffold staircase can be created.
  • At least all middle step elements and in particular also a lowermost step element can each be coupled to the two side cheeks.
  • a top step element can be designed for design considerations such that it is not with the side cheeks, but only with the step element immediately below and optionally other components of the scaffold staircase, such as a horizontal bar or a scaffold decking, coupled.
  • a step element can form exactly one step of the mounted scaffold staircase. In principle, however, it is also possible for a step element to form two or more steps.
  • the staircase elements are each secured against being lifted off by step elements arranged directly above it.
  • a particularly stable and reliable scaffolding staircase can be created.
  • An uppermost step element can be secured against lifting by a scaffold covering adjoining the uppermost step element.
  • the scaffolding staircase can be particularly quickly and easily assembled and disassembled when two step elements by threading, insertion, insertion or intervention of one or more fasteners of a step element in or through one or a plurality of recesses of an adjacent staircase step element can be coupled.
  • a kind of hinge or a rotatable joint can be formed by the connecting element and the recess, so that the two step elements can be converted by turning or pivoting relative to each other from a starting position enabling lifting of the upper of the two step elements into an end position which prevents such lifting.
  • no further components such as screws and nuts for forming the coupling connection are necessary.
  • a step element in particular seen in cross section, has two legs, one leg being designed as a step and the other leg as a riser for connection to an adjacent, in particular underneath, step element.
  • the tread preferably extends at least substantially horizontally, so that a person up or down the scaffolding stairs can find a secure footing.
  • the preferably substantially vertically extending riser can be provided as a kind of protective device, so that a person with one foot or even one leg can not or can not get too far between two adjacent treads.
  • At least one connecting element in particular a straight, obliquely or at right angles to the leg or a portion thereof away extending tab, and in the other leg, in particular in the one leg facing away from the end portion, at least one recess may be provided in the leg with mounted scaffold staircase at least one connecting element of engages a leg of an adjacent, in particular arranged below step element.
  • At least one leg is angled along at least one edge extending in the transverse direction of a step element.
  • the end portion of the tread facing away from the riser can be angled upwards, so that a person can haptically recognize the depth of the tread.
  • a section of the riser may be angled backwards to increase the depth of the tread.
  • a particular smaller portion of the riser may be angled forward to form a lift-off.
  • staircase elements are each made from a single sheet element by punching and bending, i. the staircase elements are each formed in one piece.
  • the staircase elements are therefore particularly easy to produce.
  • step elements particularly easy; wear and handle, can be formed in step elements, in particular risers, each a handle opening.
  • the holding devices are mounted on both side cheeks, preferably welded.
  • holding devices are provided at least for the middle step elements and the lowest step element.
  • a holding device has at least one of the side cheek, in particular upwardly projecting, hook-shaped or mushroom-shaped projection which engages mounted scaffold stairs in a lateral recess of a stair step element or a lateral opening of a stair step element.
  • a holding device has two projections, in particular one behind the other, wherein in particular one projection engages in a lateral recess and the other projection in a lateral opening.
  • the engaging portions of the two projections are preferably facing each other, so that when mounted scaffold staircase the step element, in particular its riser between the two projections is arranged so as to prevent movement of the respective step element in the longitudinal direction of the scaffold staircase.
  • the provided on the side cheeks holding devices may each have a support surface on which at least a portion of a stair tread element, in particular a trained as a tread leg, can be supported. This ensures that the majority the weight, which acts under load on a step element, is supported directly by the side walls and does not have to be borne by the coupling joints with the adjacent step elements.
  • one end of the side cheeks of the scaffold staircase according to the invention can be supported for example on the ground and the other end can be fixed to a wall, for example.

  • a top step element may differ structurally from the other step elements.
  • the tread of the top step element may be designed differently or be completely omitted, especially if a scaffold covering connects to the top step element.
  • the top step element can be designed such that it can not be coupled to the side cheeks.
  • At least a plurality of staircase elements are formed equal to each other.
  • the middle step elements and the lowest step element are the same.
