  • the invention relates to a modular staircase, in particular a scaffolding staircase, with a compensating element according to the invention and a method for expanding a modular staircase, in particular a scaffolding staircase, using a compensating element according to the invention.
  • Modular stairs can usually be easily dismantled and reassembled in another location.
  • the height conditions at the other location may require height compensation by extending the staircase by one or more steps.
  • the number of steps on a modular staircase should therefore be variable in order to be able to adapt the staircase to the respective local conditions.
  • DE 202011 002694 U1 discloses a modular staircase that includes an initial module, an end module and at least one expansion module that can be screwed together. Each module forms a level. For each additional stage, another expansion module is placed between the initial module and the final module. In this way, stairs with any number of steps can be created so that height compensation is possible. However, in order to install the further expansion module, the start or end module must first be dismantled, which is time-consuming and cost-intensive.
  • the invention is based on the task of expanding a modular staircase to simplify any number of steps. In this way, time and costs are to be saved. At the same time, the number of components, especially special components, that are required for expansion or height compensation should be reduced. The same components for extension or height adjustment should be able to be used both at the entrance and at the exit of a staircase.
  • the proposed compensating element enables an extension of a modular staircase, in particular a scaffolding staircase, both in the area of its entrance and in the area of its exit. This means that the stairs can be expanded in both directions using the compensation element.
  • the compensating element includes: a tube, in particular a rectangular tube, with a longitudinal axis and with a first end section and a second end section, a console for receiving a step element, the console being connected, preferably welded, to the pipe in the area of the second end section and is arranged at an angle, in particular perpendicularly, with respect to the longitudinal axis of the tube,
  • Connecting means for connecting the pipe to a vertical stem and/or a vertical stem element wherein the connecting means in the region of the first end section and in the region of the second end section are each connected to the pipe via console-like holders, preferably welded, and wherein the console-like holders are angled, in particular are arranged vertically with respect to the longitudinal axis of the tube.
  • the proposed compensation element thus forms a cheek and a railing at the same time.
  • the vertical support element is an element of a conventional vertical support, so that no special component is required.
  • the Vertical support element enables the installation of a compensating element where there is no vertical support. This is usually the case with a multi-stage extension to the staircase, so that the vertical support element replaces the missing vertical support. If there is a vertical support, the compensation element can be connected to it using the connecting means provided. This means that only one type of connecting means is required to connect a compensating element to a vertical post and/or a vertical post element.
  • the compensating element is the only special component that is required to expand the staircase. In this way, costs can be saved because fewer special components have to be kept in stock. In this context, it also proves to be advantageous that the compensating element can be mounted both to the left and to the right of the flight of stairs.
