Henninger Tower in 2005
The Henninger Tower was a grain silo of the Henninger Bräu AG in Frankfurt am Main. The 1959 to 1961 in the Sachsenhausen district built with a total height of 119.5 m tower was demolished in 2013.
In the lower part of the building 87.45 m high basement rooms, the entrance, a pub called Turmschänke plus kitchen, also a distributor and floor ( from 2nd floor) were the silo. In addition there was the striking, resembling a barrel and offset built tower basket. This upper part round tower contained, in addition to a viewing platform at 110 meters above sea level first one, from 1970, two, last but again only one ( occupied ) revolving restaurant.
The architect was Karl Emil Lieser. The inauguration took place on 18 May 1961. Until 1974, the Henninger Tower remained the tallest building in the city of Frankfurt. Since 2002, the tower was closed to visitors. In 2012 it was decided that the tower should be demolished to make way for a 130 -meter residential tower space. This is, however, strongly guided by the appearance of the Henninger Tower.
In January 2013, the demolition work, which lasted until the end of the year and almost EUR 1.5 million cost began.
Specifications
Shape and construction
The Henninger Tower consisted of two components, the rectangular silo and the cylindrical tower attachment, including towers basket. Formally it was planned so that the impression should arise if it were a dynamically rising from the ground round tower and a rectangular body which surrounds the former almost entirely. On the drawing of the original space sets of the tower restaurants, this suggestion is clearly visible: the glazing of the main staircase was run slightly curved outwards, to make the stuck in the square cylinder for the viewer to read.
There was a continuous closed (except for the staircase and the window front ) tower shaft in solid construction which was necessary to achieve the separation of the silo unit from the public.
The entire structure was based on a 25 × 25 m wide and 1.25 m thick foundation slab made of reinforced concrete, the distributed forces to the underlying bedrock. The building was listed on 36 concrete columns that passed through all the floors and upwardly tapered, wherein each outer 6 columns directly with the outer walls, the remaining 16 Although detached but below the basement ceiling - by reinforced concrete trusses went up to the outer supports - also were interconnected.
The continuous reinforced concrete elevator shaft was enclosed by a semi-circle with 7.3 m diameter and led the way up the tower basket. Contrary to the Frankfurter Aufbau source at least the elevator shaft was made entirely of sliding formwork. The concrete work to the memory cells were carried out in a conventional timber formwork. From there, the tower was built in sliding formwork. The distribution storeys above the silo cells were formed conventionally again, according to the source structure. The outer wall of the cylindrical tower attachment was 24-21 cm thick, this resulted in each twenty cantilevered support brackets a ceiling of the tower basket.
These four elements - full elevator and stair shafts, massive Siloaußen and separation walls and columns on a square grid and the tower cylinder - attended the Association for the necessary stability.
The building had a deadweight of 17,335 tonnes and a maximum total weight of 31,611 tons. The floor plan was square with dimensions 20.68 × 20.68 m. The required silo storage volume was 14,000 tonnes.
Silo
The silo had a roof height of 87.0 m. In the 3.5 m deep basement of the tower there were machines and store rooms. On the first floor 4.1 m in height there was the old unloading, for bulk material. This resulted in a bridge on the opposite side of the path Hainer in the brewery. In addition there were 32 massive memory cells in barley and malt, together amounted to 14,276 t their capacity. The maximum lateral pressure on the 18 cm thick reinforced concrete separating walls was 4.5 t / m². At the level at 72.8 m height ( 17.OG ) a 5 m high floor distribution for the bulk material was housed. This can be read on the facade through the lower of the three rows of windows with elongated, stationary window formats. The two rows of windows above from approximately square formats expose the second ( 19.OG ) and third ( 20.OG ) floor, in which electrical installations and lounges were. The 20.OG was half a mezzanine, which was present only on the side of the tower to the city.
The encircling band of windows above the 21st floor was formed from the restaurant, which was functional already attributed to the tower with its visitor traffic. The restaurant was set up as the last stage in the silo 82.8 m height and had a floor height of 4.2 m. It was oriented towards the Frankfurt skyline. On the opposite side of the silo in the direction of Frankfurt's skyline, the passenger elevators and the main access stairs were. Originally, the restaurant was designed as a kind of open roof garden. In the middle were flower beds, a dance floor and water games and on the edge about the tables were grouped, the. Pass through a 2 m wide accessible roof were protected from the weather. Around 1970 it was rebuilt as a full basement with large skylights and included after various meeting rooms and a café.
Observation tower
The tower tower had a height of 31.5 m, which led to a total height of 119.5 m. The outer walls of the shaft were in the amount of the restaurant has a diameter of 7.3 m. The observation deck was opened to the public by any two persons 15 comprehensive high-speed elevators with a travel time of just over two minutes to go from the ground floor. In the glass (except for the first two floors) main staircase you reach the viewing platform above 596 levels. The ground floor was the first elevator stop. For developing the tower stairwell (main steps) was 40.3 m height of the second elevator maintenance. The 3rd and 4th stop opened up the two switching or distribution storeys and the 5th stop the conservatory restaurant.
In the tower there were first basket until ~ 1969 two, later three more all-glass shells with a diameter of about 16 m. The 6th elevator landing opened up in the first level of the control tower ( 26.OG ) to 95.7 m height, the restaurant kitchen and the toilets. The plan was initially here a so-called " Frankfurt office ." In the plane above 100.3 m in height and lift stop number 7 ( 28.OG ) there was a revolving restaurant. A revolution took here first 30 minutes, but was slowed down later on 60 minutes. The 8th and top elevator landing ( 30.OG ) formed the third level of the tower basket to 106.4 m height. This was originally designed as an open observation deck on the roof of the revolving restaurant. Around 1970 this was eventually rebuilt as a full basement with a second revolving restaurant. But this was only a few years in operation, since the management of two revolving restaurants became unprofitable. The wear of the rollers that turned the soil, lead to the conclusion that these were either barely run or oversized, since one could still detect a significant impact on the manufacturing process just before the final disassembly. Only accessible via the stairs ( 31.OG ) was located above the tower cage around the tower shaft in 109.2 m a small open observation platform with coin-operated telescopes.
Revolving Restaurant
The / the revolving restaurant ( s ) never turned himself, but the floor was designed as a ring, which could rotate around the tower shaft. For this purpose, a steel frame was fixed on the ground, the 80 solid rubber wheels in size 465 / 65-305 included. These were distributed in two rings, with 40 divided up in the inner and 40 wheels on the outer ring. The floor was rotated by an electric motor force over a chain-like teeth on a ring centrally mounted. There were several inspection holes in the rotating floor, could get to the bogie by the fitters. For this purpose, fixed mounted lights were installed. These details were considered for the two used as a revolving restaurant floors.
Both revolving restaurants and their floors were connected by means of two dining lifts, with 50 kg payload with the kitchen on the base drum.
There was a passenger elevator for the kitchen staff, who both kitchens and public spaces connected directly and an elevator for the brewery staff.

And in 2014 after the demolition of the Henninger Tower
Since 31 October 2002, the Henninger Tower for the visitor traffic was closed because of the fire was not guaranteed by the absence of a second escape route.
In November 2012 it was announced that the tower will be demolished to make room for a 130 m high residential tower. This should be outwardly similar to the Henninger Tower and house several luxury apartments. Also restaurants and shops are planned on the 4,000 m² terrain.
In 2005, the grain silo of Schapfenmühle has replaced in Ulm- Jungingen the Henninger Tower as the world's highest silo tower still in use.
To advertise with the tower, was from 1962 to 2008 every year round hosted by the Henninger Brewery and the Society for the Promotion of cycling the bicycle race around the Henninger Tower on May 1. The start and finish of the cycling race was always close to the tower, but was partly shifted from year to year. Was the Start-/Ziellinie 1962 nor in the amount of the current Ferrero- new building, this was placed in the 80s and 90s always near the Silobrücke of the tower. After the end of its sponsorship of the Henninger brewery the race under the name Eschborn -Frankfurt City Loop was continued. In December 2009 it was renamed once more in around the financial center of Eschborn- Frankfurt.
In succession to
On the Henninger Tower plot the construction of a 130 meter high residential tower is planned, which will be based on the dimensions and the appearance of the old tower. The massive (in this case, however, rectangular ) shape and the round six-storey tons of paper are modeled so that its familiar silhouette remains.
