In November 2012, the new Emporio Armani store opened its doors in the city centre of Vienna. A convincing and outstanding architectural highlight is the construction of the self-supporting stairs, which look like a sculpture in the stylish interior finishing of the showrooms. The construction and design of the self-supporting stairs with closed parapet-high stringers perfectly complies with modern style in architecture. This is largely due to the soffit lining, which is shaped by the spiral run of the stairs.
With an inner diameter of 1,200 mm and an outer diameter of approx. 4,280 mm, this four-radius point circular staircase layout has a flight width of approx. 1,300 mm. The parapet-high stringers of the stairs consist of rectangular hollow sections in a closed-box design. The steps feature a folded-stairs design and are welded in between the stringers of the stairs. The spiral staircase is anchored with a steel base plate to the unfinished floor ensuring a force-fit connection.
