Die vorliegende Erfindung betrifft eine Treppe für den Treppenturm auf Basis eines Modulgerüstes. Die vorliegende Erfindung betrifft ferner die Treppenwangen und die dazugehörigen Treppenstufen.The present invention relates to a staircase for the stair tower based on a Modular scaffolding. The present invention further relates to the stair stringers and the associated stairs.

Gerüste werden heutzutage immer öfter mit einem Treppenturm ausgerüstet, durch den die Arbeiter auf die verschiedenen Ebenen des Gerüstes gelangen und durch den Lasten transportiert werden können. Die Treppen eines solchen Treppenturms müssen massiv ausgeführt werden, damit sie hinreichend belastet werden können. Diese massive Ausführung hat den Nachteil, daß die Treppe selbst oder die Einzelteile aus der sie montiert wird oftmals schwer und damit unhandlich sind.Nowadays, scaffolding is increasingly equipped with a stair tower which the workers get to and through the different levels of the scaffolding which loads can be transported. The stairs of such a stair tower must be carried out massively so that they can be sufficiently loaded. This massive design has the disadvantage that the stairs themselves or the Individual parts from which it is assembled is often heavy and therefore unwieldy.

Es bestand deshalb die Aufgabe Treppenteile mit einem geringen Gewicht zur Verfügung zu stellen, die leicht montierbar sind.There was therefore the task of stair parts with a low weight To provide that are easy to assemble.

Die Aufgabe wird erfindungsgemäß durch eine Treppenwange gemäß Patentanspruch 1 gelöst.

Zwischen dem Obergurt und dem Untergurt sind außerdem Sprossen angebracht, an denen die Treppenstufen befestigt werden.The stair stringer according to the invention has an upper chord and a lower chord, which are preferably connected to each other by two end posts. Between The top and bottom chords are also attached to rungs the stairs are attached.

Diese Sprossen weisen erfindungsgemäß mindestens zwei Schlitze auf, die die Einhängebolzen einer Treppenstufe reversibel aufnehmen.According to the invention, these rungs have at least two slots which form the Reversibly pick up the suspension bolts of a stair step.

Die Schlitze können an den Sprossen in jeder dem Fachmann geläufigen Weise angebracht werden.The slots can be on the rungs in any manner familiar to those skilled in the art be attached.

Vorzugsweise werden jedoch an den Sprossen Schlitzbleche angeschweißt, in die Schlitze eingearbeitet sind. Ebenfalls bevorzugt werden die Schlitze in die Sprossen gestanzt, gefräst oder eingeprägt. Ebenfalls bevorzugt wird in die Sprosse eine Schlitztaschen gedrückt, in die die Schlitze eingearbeitet werden.However, slotted plates are preferably welded to the rungs, into which Slots are incorporated. The slots in the rungs are also preferred punched, milled or embossed. Also preferred is one in the rung Slit pockets pressed into which the slots are worked.

Vorzugsweise weist jeder Schlitz eine Öffnung auf, durch die die Einhängebolzen einer zu der erfindungsgemäßen Treppenwange passenden Treppenstufe in die Schlitze einführbar ist. Durch diese Öffnung kann die Treppenstufe auch wieder von dem Schlitzblech gelöst werden.Each slot preferably has an opening through which the suspension bolts a step matching the stair string according to the invention in the Slots is insertable. Through this opening, the stair step can also from the slotted plate can be solved.

In einer bevorzugten Ausführungsform ist ein Schlitz parallel zu der Längsmittelachse der Sprosse und der andere Schlitz in einem Winkel von 25°-155°, vorzugsweise 45°-135° bezogen auf die Längsmittelachse der Sprosse angeordnet. Besonders bevorzugt beträgt der Winkel 85°-95°, ganz besonders bevorzugt 90°. Diese Anordnung hat den Vorteil, daß die Treppenstufen an den Treppenwangen leicht montiert und nicht losgetreten werden können.In a preferred embodiment, a slot is parallel to the longitudinal central axis the rung and the other slot at an angle of 25 ° -155 °, preferably 45 ° -135 ° based on the longitudinal central axis of the rung.
