BUILDING BLOCK Russian patent published in 1996 - IPC

FIELD: civil engineering. SUBSTANCE: building block includes monolithic body with at least one open cavity filled with other material. Surfaces that form cavity are made in the form of elliptic paraboloid or two- cavity hyperboloid, or hyperbolic cylinder, or cone of the second power, or parabolic cylinder, or elliptic half- cylinder. With surfaces that form the cavity in the form of two-cavity hyperboloid, or hyperbolic cylinder additional cavities are originated on adjacent planes of the block, in so doing the surfaces that form them are made in the form of two-cavity hyparboloid and hyperbolic cylinder respectively. With surfaces that form the cavity originated in the form of elliptic paraboloid, or parabolic cylinder, or elliptic half-cylinder additional cavities are originated on opposite planes. In so doing the surfaces that form them are made in the form of elliptic paraboloid, or parabolic cylinder, or elliptic half-cylinder. The surfaces that form the cavity are made in the form of elliptic paraboloid, or two-cavity hyperboloid, or hyperbolic cylinder, or cone of the second power, or parabolic cylinder, or elliptic half-cylinder. Additional cavities filled with other material are originated in forming surfaces that form the cavity. In so doing surfaces that form the cavities are made in the form of two-cavity hyperboloid and hyperbolic cylinder. With surfaces that form the cavity being in the form of elliptic paraboloid, or parabolic cylinder, or elliptic paraboloid, or parabolic cylinder, or elliptic half-cylinder. additional cavities filled with other material are originated on opposite planes of the block. In so doing surfaces that form them are made in the form of elliptic paraboloid, or parabolic cylinder, or elliptic half-cylinder respectively. EFFECT: labour consumption. 6 cl, 3 dwg
