The helical chute surface (10) comprises a fixed, concavely drawn material in which are cable sections (12) fixed to separate coil sections. The chute surface is screwed on until the cable sections run vertically. The modular structure has a top (14) and bottom (16) ring. The top ring of one module is fixed to the bottom ring of the module on top of it. Each module has a climbing element (17) suspended from the top ring. A textile covering (18) extends between the rings.
