The Jübergturm is a 23.5 m high observation tower in the area of the North Rhine-Westphalian city of Hemer , which was built for the Hemer State Horticultural Show in 2010 . The building, which is part of the Sauerlandpark Hemer today, is the city's new landmark.
Geographical location
The Jübergturm stands about 565 m south-southwest of the summit of the Jüberg ( 305.2 m above sea level ). It is located in the Sauerland Park Hemer, which emerged from the site of the Hemer State Garden Show 2010 , at a height of 293.7 m . It has been made accessible since 2010 by a staircase called the Himmelsleiter and the barrier-free zigzag path , both of which come from the direction of the city center and begin in the former site of the Blücher barracks .
history
Originally, a construction consisting mainly of reinforced concrete with wide stairs was to be built according to a design by the Swiss architects Beat Müller and Katharina Schewe. For reasons of nature conservation this draft was rejected, so that new drafts were prepared. The main material should now be wood. After protests from the population, interested citizens were asked to vote. With a narrow majority they chose the somewhat smaller design by the Swiss architects, but modified as a stair-like wooden construction.
For financial reasons, however, only the second-placed design was implemented from January 2010, which was planned by a joint venture between the Stuttgart architects Birk and Heilmeyer and the engineering office Knippers Helbig . This is based on the work of the Russian engineer Wladimir Grigorjewitsch Schuchow and is similar to the Lörmecke tower in Warstein , which is why the Warsteiner mayor Manfred Gödde complained against the Hemeraner decision: The tower was built as a freely weathered wooden structure made of Siberian larch .
The construction of the tower was supported by the Stadtsparkasse Hemer Foundation with around 450,000 euros. After night work in the last few weeks, the tower was completed on April 16, 2010 and officially approved. One day after the start of the state horticultural show , the tower was officially opened for the event. The official ceremonial handover of the Jübergturm to the citizens of Hemeran was carried out by the representative of the Sparkassenstiftung's board of trustees on September 5, 2010.
construction
The principle of hyperbolic grid shells by the Russian engineer Vladimir Grigoryevich Schuchow was adopted and further developed for the tower . The Schuchow principle was implemented in wood. According to the architects, it is the first real wooden bar hyperboloid in which only the outer frame supports.
The observation tower, which tapers towards the base, has a height of 23.5 m and is located at a height of 293.74 m . The outer construction of the round tower consists of two levels with a total of 240 straight squared timbers , which run upwards at an angle in opposite directions and are connected to one another. The two levels consist of 120 square timbers each with a cross-section of 8 cm by 8 cm.
On the inner and outer levels of the outer construction there are alternating 20 by six pieces of wood of different lengths. Wood one ends just above the first platform, wood two just above the second platform and so on. Timbers five and six end 1.62 m above the fifth platform.
The viewing platforms are at heights of 4.38 m ( 298.12 m above sea level ), 8.75 m ( 302.49 m ), 13.13 m ( 306.87 m ), 17.50 m ( 311 m 24 m ) and 21.88 m ( 315.62 m ).
Inside the tower, five flights of stairs with a total of 125 steps lead to the top platform. As the number of squared timber running upwards decreases from platform to platform, the tower becomes more and more open.
Possibility of viewing
From the observation deck of Jübergturms visitors get the view among others to the west down to Hemer with the former in the Sauerland Blücher barracks and on the eastern plateau with parts of the former site training area as well as on the grounds of the Sauerland parks Hemer .
