A scaffolding arrangement for a building outer wall, comprising a plurality of anchor bolts arranged at a distance from each other at least in the horizontal direction, including tube clamps connected to the anchor bolts, a horizontally extended rail, the rail being fixed to the tube clamps, a scaffolding as well as a connecting device for fixing the scaffolding to the rail. The connecting device provides a first coupling encompassing the rail as well as a second coupling encompassing a tube element of the scaffolding and a coupling connector for connecting the first coupling to the second coupling.

A steel-structure building envelope capable of erecting a scaffold and a method for erecting the scaffold are disclosed. The scaffold is fastened to the steel-structure building envelope through two steps fastening means. A pre-embedded reinforcing steel bar is laid in each of RC slabs and extends out of the corresponding RC slab to be wound around the scaffold, serving as the first fastening means for fastening the scaffold. Locking parts are embedded into the corresponding RC slab at intervals. The transverse aluminum extrusion is disposed on an outside of the corresponding RC slab. The wall connecting rods each have a first end that passes through the transverse aluminum extrusion and is locked to the corresponding locking part and a second end configured to lock the scaffold, serving as a second fastening means for fastening the scaffold after the pre-embedded reinforcing steel bar is removed from the scaffold.
