BUILT-UP-MONOLITHIC REINFORCED-CONCRETE FRAME OF MANY-STORIED BUILDING "KAZAN-100" Russian patent published in 2002 - IPC

FIELD: civil engineering, in particular, construction of domestic and public buildings. SUBSTANCE: the built-up-monolithic reinforced-concrete frame of the many-storied building has built-up reinforced-concrete columns with holes, built-up prestressed cross-bars and slabs with a clearance between their end faces, the slabs are made as multi-hollow ones, the slab end face surfaces resting on the cross-bars are inclined to the slab plane at a slope of 25 to 30 deg., and the cross-bars on the end face edges have horizontal triangle-section recesses, the clearances between the slab end faces and the holes in the columns are monolithic- finished integral with the free lengths of reinforcement bars of the built-up members of the frame. EFFECT: provided a new flexible bearing structural frame system at a reduced specific consumption of materials and labor content at erection and enhanced prefabricability of construction and building stiffness. 4 cl, 9 dwg
