IMPROVEMENTS RELATING TO COMPOSITE PANELS WITH DUAL COATING Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: composite panel with dual coating has two steel facing plates of 2 to 32 mm thickness which are connected to each other by lateral members. Each lateral member is located in perpendicular with respect to facing plates and is away from adjacent lateral members at distance which is equal to 10-80 thicknesses at centers of facing plates. Spacing between facing plates is from 30 to 800 mm. Spacing between facing plates is filled for example with concrete. Application of aforesaid improvements ensures required strength characteristics of panel without increasing its weight. EFFECT: higher efficiency. 18 cl, 12 dwg
