PRESTRESSED REINFORCED CONCRETE FRAMEWORK OF BUILDING Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: reinforced concrete framework is intended basically for low-storied buildings. Framework incorporates columns with passages made at level of ceilings in two mutually perpendicular directions. Also provided are ceiling slabs, and prestressed reinforcement inserted through rows of slabs and through passages in columns. Prestressed reinforcement is anchored in columns and concreted in passages and in joints between slabs. Passages in columns in longitudinal direction are of round cross-section, and in lateral direction passages are made in the form of rectangular slots, and seated in these slots are vertical metal frames. Prestressed reinforcement in longitudinal direction is inserted through passages and frames and is anchored on external faces of extreme columns. Prestressed reinforcement in lateral direction is inserted through slots and is anchored on frames with location of lateral and longitudinal reinforcement in common plane at level of ceiling. Frames in extreme columns are secured on their external faces. Application of aforesaid embodiment of framework allows for reduction of amount of materials needed in production together with less labour cost in erection. EFFECT: higher efficiency. 2 cl, 10 dwg
