GIRDERLESS FLOOR Russian patent published in 2009 - IPC E04B5/43 

FIELD: construction.

SUBSTANCE: invention relates to construction, particularly to a girderless floor. The girderless floor comprises a column without a head and flat slab. In the body of the slab there is an n-branched cantilever with circular and radial principal reinforcement, the nodes of which coincide with the axis of the column. Branches of the n-branched cantilever are rigidly attached to a pipe cutting. The pipe cutting is put inside the column such that, the axis of the pipe cutting coincides with the axis of the column. The length of the circle of the pipe cutting is greater than the total width of limbs of the branches of the n-branched cantilever. The length of the pipe cutting is determined by the total moment of deflection in the branches of the n-branched cantilever.

EFFECT: simpler process of concreting slab-column structures at their joints.
