Description

background

The present invention relates to a banister for a scaffolding system. The invention further relates to a scaffolding system. The invention also relates to a method for assembling a banister for a scaffolding system.

Stairways are increasingly replacing access platforms with scaffolding systems. In the case of a scaffolding system provided with one or more stairs, it is necessary to secure a staircase by means of an appropriate stair railing.

Existing stair railings for scaffolding systems have the disadvantage, however, that the stair railings can only be assembled and disassembled safely if a user puts on personal protective equipment against falling. However, the construction of the stair railing for the scaffolding system when using personal protective equipment against falling is more complex and takes more time.

Without the appropriate protective equipment, existing stair rails cannot be installed from a safe position, since a worker would have to climb the unsecured staircase for this.

DE 10 2005 028 885 A1 discloses a scaffolding staircase with two separate side walls and a plurality of separate stair tread elements, which can be detachably coupled both to one another and to the side walls. Furthermore, a stair railing is attached to the corresponding rosettes of the vertical supports. Here, too, the stair railing at the top of the staircase must be hung from an unsecured position at the top of the stair, as this cannot be done otherwise due to the design.
