METHOD FOR MANUFACTURE OF THREE-LAYERED WALL PANEL Russian patent published in 2002 - IPC

FIELD: manufacture of sandwich concrete and reinforced concrete. SUBSTANCE: method consists in successive placement of reinforcement rigging and concrete of the outer layer on a preheated bottom plate under the action of vibration. Then, a heat-insulating layer in the form of a core of expandable polystyrene plates framed by mineral wool elements around the outer and inner edges is installed on it, the reinforcement and concrete of the inner layer are placed on the heat- insulating layer under the action of vibration, the concrete of the inner layer is rubbed down manually. Subsequent heat-moisture treatment under the heat- insulating canopy, dismantling of the forms, turning-over to the vertical position and installation of a ready-made window block are accomplished. EFFECT: enhanced indices of power intensity. 3 cl, 3 dwg
