floors

Typical prefabricated carcasses with a regular grid of columns and a constant height of floors were used mostly in the construction of multi-storey buildings for different purposes, for many previous decades. Such typical prefabricated and non-typical carcasses have several drawbacks: diversity of the prefabricated elements, complexity of installation, high work content and cost of construction. During almost half a century, the use of prefabricated reinforced concrete structures has been developed and implemented many typical designs and technologies for their manufacture at factories.

Creating innovative design concepts and effective, economic and technological reinforced concrete multi-storey circular ramp and parking garages. The methods of forming the surfaces of open helicoid as floors circular ramp multi-storey car garages.
