TALL BUILDING Russian patent published in 2009 - IPC E04B1/18 

FIELD: construction industry.

SUBSTANCE: invention refers to construction of tall buildings with increased operating reliability. Tall building consists of foundation construction, central load-carrying stiffness shaft made from cast-in-situ reinforced concrete, composed tubes and concrete, composed steel and concrete, or their combinations, and structural frame system - multi-layered bents with support platforms made in the form of staged box-section structures of cast-in-situ reinforced concrete plates connected by orthogonal separation walls that are supported from load-carrying tube-and-concrete columns. The latter are located at the periphery about central shaft, with attachment points to the flooring disks, and with vertical stiffening diaphragms made of cast-in-situ reinforced concrete. There are enclosing structures that are rested on floorings. At that columns are connected by attachment points to each other and to flooring disks in the form of packages composed at the site of pre-stressed reinforced concrete plates, including with reinforced, storey-by-storey, floorings made of pre-stressed reinforced concrete plates braced with steel ropes the ends of which are provided with anchors fixed storey-by-storey in stiffness shaft walls and opposite steel beams connecting columns; and cast-in-situ reinforced concrete plates of staged box-section structures of support platforms are made with stress on steel rope plate concrete between external outline of support platforms and central stiffness shaft walls.

EFFECT: speeding-up construction process, increasing number of storeys, improving building reliability and safety, and reducing labour cost and construction cost.
