Abstract (en)
The stair framework for an earth-connected installation in a slope has two stair stringers (1) and at least one riser (2) releasably connected to the stringers. The stair stringers are each formed from several segments (1.1), whereby the riser is provided with connecting plates (3) extending transversely to their front face and to which are fastened two consecutive stringer segments. The connecting plates are constructed in one piece on the stair riser. The connecting plates consist of sections which are splayed in relation to a longitudinal plane of the respective riser.
