REINFORCED CONCRETE STRUCTURE Russian patent published in 2004 - IPC

FIELD: building units, particularly reinforced concrete panels.

SUBSTANCE: structure has strapping orifices. Inserted in strapping orifices are reinforcement rods performing strapping and having cross-sections calculated by the following expression where A_s is rod cross-section, cm²; P is designed force applied to reinforcement rod, kgf; ς_ul is designed maximum permissible stress in reinforcement rod, kgf/cm² and δ is designed percent elongation of reinforcement rod, %. Strapping orifices are spaced a distance equal to or exceeding anchoring depth from reinforced concrete structure ends extending perpendicular to reinforcement rods.

EFFECT: reduced metal consumption.
