REINFORCED CONCRETE PLATE OF PREFABRICATED COVERING Russian patent published in 1995 - IPC

FIELD: airfields construction. SUBSTANCE: concave form lower surface of prefabricated covering reinforced concrete rectangular plate is made cylindrical with guide, that is symmetrical about middle of plate's length, or prismatic, inscribed in the cylindrical surface, that is symmetrical about middle of plate's length. In the case, value of rise is determined according to given dependance. Lower surface of prefabricated covering reinforced concrete rectangular plate is in its length middle part made cylindrical with guide, that is symmetrical about middle of plate's length, or prismatic, inscribed in the cylindrical surface, that is symmetrical about middle of plate's length. Value of rise is determined according to given dependance. Edge parts of plate, values of length of which are determined by given dependance, have lower surface of plate, that is in parallel to its upper surface. EFFECT: prefabricated covering reinforced concrete rectangular plate is used in airfields construction. 8 cl, 4 dwg
