The relatively new sport ‘Topgolf’ from America is also finding more and more fans in Europe. A new course was also built in Vienna.
It consists of a building from which golf balls are hit and a symmetrical, almost parabolic playing field in front of it. The playing field is surrounded by a net up to 55 m high, which catches the golf balls and prevents them from leaving the course.
The net is attached to the pylons and spans eleven fields, with different spans depending on the axis. The plastic net is connected to the pylons via horizontal cables and a yarn connection with an integrated predetermined breaking point. The size of the individual net segments is determined by the width between the pylons and the distance between the horizontal cables. The nets are held or “suspended” vertically by an upper supporting cable and additional vertical cables. The net is additionally fixed to the ground by a strip foundation.
The pylons are supported at the rear by a truss structure. Both the pylon and the truss members are designed as circular hollow sections. At the heights of the two truss connections, the pylons are additionally braced with cables, with the two upper cables spanning to the next axis and the two lower cables to an additional support in the middle of the axes. Two additional stay cables for the middle truss point improve the buckling behavior of the truss structure. They also tension in the direction of the middle support.
