FLEXIBLE AND OFF-CENTER COMPRESSED BUILDING UNIT MADE OF EXTRA LIGHT-MASS CONCRETE Russian patent published in 2001 - IPC

Abstract RU 2163285 C1

FIELD: construction engineering. SUBSTANCE: building unit has reinforcing members, anchoring members, and concrete; anchoring members are made in the form of reinforcing members; proportion A_1ex1/A₅ is between 300 and 1000, where A_ex1 is surface area of anchoring members imparting force to extra light-mass concrete; A₅ is cross-sectional area of reinforcing members. Building unit has at least one reinforcing member; each anchoring member is rigidly fixed to at least one reinforcing member; anchoring members are made in the form of rolling sections, anchoring rods, and anchoring strips. Anchoring members have closed cavities filled with light-mass heat- and sound insulating material or air. Anchoring members are made with open cavities filled with light-mass heat- and sound insulating material or air. EFFECT: improved heat- and sound insulating characteristics. 5 cl, 2 dwg
