Erecting a wall and creating an installation opening
Erect the shaft wall according to the manufacturer's instructions and create an installation opening with rein-
forcing strips, see Fig. 77
– Option A: Create an opening in the cladding and reinforce it along the perimeter.
– Option B: Provide the installation opening in the metal support structure with support sections. Install four
additional sections at an angle of 45° in order to reinforce the metal support structure.
Fix the cladding and reinforce the installation opening along the perimeter.
