PREFABRICATED MONOLITHIC REINFORCED CONCRETE FRAME OF MULTI-STOREY BUILDING Russian patent published in 2023 - IPC E04B1/20 

FIELD: construction.

SUBSTANCE: prefabricated monolithic reinforced concrete frame buildings. A prefabricated monolithic reinforced concrete frame includes reinforced concrete columns, prefabricated monolithic crossbars and hollow-core floor disc slabs. The columns of the second floor have prestressed reinforcement along their entire length to the height of the column, including the height of the two floors. The prestressed reinforcement bars are fixed on crossbeams resting on the longitudinal reinforcing bars of the columns. The ends of the outlets of the lower working reinforcement of the prefabricated part of the load-bearing crossbars are bent upward, inserted into the body of the overlying column and connected to its working reinforcement. The monolithic part of the crossbars is concreted together with recesses made for installing traverses located on both sides of the prestressed columns of the second floor.

EFFECT: improved resistance of such a frame to progressive collapse.
