Sliding construction
The sliding construction method (also sliding construction method or sliding formwork production ) is a construction technique in concrete construction in which the formwork moves with it. It represents a possible alternative to the newer climbing construction method. The method has been known in Germany since 1927, because the Weldweit first residential house in sliding construction was only built in 1950 in Stockholm , Sweden.
The sliding construction method is mainly used for high concrete structures (e.g. towers, chimneys, high-rise buildings). The formwork elements are not moved, but the formwork ( sliding formwork ) is continuously pushed on in accordance with the progressing construction on the structure and supported on the already concreted part, the concreting process is not interrupted. The entire formwork construction is pulled up pneumatically or hydraulically on so-called climbing poles. The concrete sets while sliding, so that it has sufficient strength at the lower end of the formwork to be able to support it. The sliding construction, in contrast to the climbing construction, must therefore run continuously in 24-hour shifts. This places high demands on the construction technology, since a continuous supply of building material must be guaranteed for the sliding process. It is also used in the construction of concrete roads or concrete barriers.
Structures that were constructed using the sliding construction method (selection):
- World's first residential buildings in Västertorp , Sweden, construction started in 1950, built by the Swedish company Bygging AB.
- Marina City Chicago, construction started in 1959
- Heinrich-Hertz-Turm Hamburg, construction started in 1966
- City high-rise Leipzig , construction started in 1968
