multi-storey system

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.

In the construction of multi-storey buildings for different purposes, for many previous decades mostly typical prefabricated frame with a regular grid of columns and a constant height a floors were used. Such typical prefabricated and custom frames have several disadvantages, complexity of installation and connection of nodes frames, diverse nature technology of prefabricated elements, high complexity and cost of construction. To avoid these drawbacks a new system of frames with irregular grid of columns and variable height floors.
