COMPLEX STRUCTURE OF COVERING Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: complex structure of covering incorporates lower H-shaped reinforced concrete plate, subdiagonal system, and warmth-conserving component. Lower reinforced concrete plate has protrusions of such height which ensures clearance between aforesaid protrusions and lower units of subdiagonal system. Clearance is equal to 5-10% of full deflection of subdiagonal system. Clearance is obtained in working position of system under action of normal component of loads that are taken by subdiagonal system. Application of aforesaid embodiment of complex covering structure allows for increasing spans of constructions together with retention of heat-insulating properties which are characteristic for three-layer plates with flexible links without cold intervals. Operational reliability of such structures is also enhanced. EFFECT: higher efficiency. 3 dwg
