MULTIPLE-VOID BUILDING SLAB Russian patent published in 2000 - IPC

FIELD: construction engineering; slabs for ceilings. SUBSTANCE: slab used for ceilings of buildings with spans smaller than 4.5 m has reinforcing cage having longitudinal working and transverse reinforcement, longitudinal vertical members between voids, mounting thimbles, and placed-in-situ concrete. Longitudinal vertical members between voids are, essentially, a number of thimble clips welded to longitudinal working reinforcement at near-support sections of slab; longitudinal working reinforcement is provided with locks made in the form of eyes welded to reinforcement and spaced 0.2-0.5 of slab length apart. Box-shaped nets with single or coupled mounting thimbles are arranged at near-support sections of slab. EFFECT: reduced consumption of reinforcement material; facilitated manufacture of reinforcement cage. 5 cl, 5 dwg
