REINFORCED CONCRETE COVERING PANEL Russian patent published in 2000 - IPC

FIELD: civil engineering. SUBSTANCE: reinforced concrete covering panel of double-T type includes flange, longitudinal ribs, reinforced concrete brackets, reinforcing fabric, additional longitudinal ribs with reinforced concrete brackets with values of constant load from roof of less than 1.40 kN/sq. m, they are located at a distance of 800 mm from panel longitudinal axis and with values of the loads above 1.40 kN/sq.m, at a distance of 775 mm from panel longitudinal axis. The technical result is reduced specific content of metal in covering panel flange with preserved bearing capacity, higher operating reliability of panel longitudinal joint, extended range of application of low grade concretes in separated manufacture of panel flange and longitudinal ribs, improved operating conditions in service with action of only constant load (in summer) or constant load together with temporary snow load (in winter). EFFECT: higher efficiency. 10 dwg, 3 tbl
