WIEHAG GmbH from Altheim, Austria, a customer of Dlubal Software, was responsible for the planning, structural analysis and design, fabrication, and assembly of the tower. Structural calculations were performed in RSTAB.
Structure
The shape of the lookout tower resembles a beaker. The structure consists of an outer ring of 12 double-sloped glulam beams, which are positioned at the same distance from each other and are rotationally symmetrical.
The 12 main columns tilt 7.7° away from the center point and are also inclined 9.4° counterclockwise. Thus, the tower looks like a slightly inclined and twisted beaker.
The tower can be accessed at the height of 5 m (16.4 ft) from the treetop trail, which winds through the treetops with a total length of approximately 1,250 m (4,101 ft) at a height of up to 20 m (65.6 ft).
You can climb up to the viewing platform on a helical structure made of wood, which is attached to the timber supports by steel cantilever beams. Between the individual cantilever beams, there are timber stringers covered with a wooden floor.
On the top of the tower, there is a viewing platform made of steel. The platform consists of steel cantilever beams that project outwards and are connected to the timber columns. The cantilever beams, in turn, support longitudinal timber beams with a plank covering.
The structure is stiffened by an encircling mesh of steel diagonals and ring structures.
