Bauen mit Leichtigkeit - Ein spannendes Montagekonzept

Construction with lightness - exciting assembly concept.

Cable-net structures are an ideal option for the construction of large stadium roofs. They are lightweight and can span large areas without obstructing columns. One or two circular compression rings above the upper edge of the grand stands act as the abutments for the cable net roof. This structural solution is obviously very efficient and compelling. But how will the cable structure be installed and tensioned? The following article should answer these questions and show the different methods for the cable-net installation with strand jacks. Depending on the type and geometry of the structure different methods for lifting and tensioning can be applied. In 2013 one of the largest membrane roofs, with a surface area of 203462 m², has been installed during the renovation of the famous Estadio Maracanã in Rio de Janeiro.
