SECTIONAL-MONOLITHIC FRAMEWORK OF MULTISTORY BUILDINGS AND METHOD FOR ITS ERECTION Russian patent published in 1997 - IPC

FIELD: construction engineering. SUBSTANCE: this framework has sectional reinforced concrete columns with holes, and ceiling slabs with embedded buts. Ceiling slabs are resting with their two opposite ends on reinforced butts embedded between them to create span-pieces built in columns. End surfaces of slabs which are adjacent to span-pieces are made inclined to slab plane at negative incline angle with mounting depth not less than 1/4 of slab thickness. Span-pieces are located unidirectional along parallel axes of building, and reinforcement of each span-piece is multiple-row with upper rods inserted through holes in slabs, and with lower rods inserted into blind sockets formed in two opposite faces of columns. Holes and sockets of columns are concreted integrally with span-pieces. EFFECT: high efficiency. 7 cl, 9 dwg
