METHOD FOR LAMINATED BUILDING ARTICLE PRODUCTION Russian patent published in 2007 - IPC E04C1/40 B28B1/00 

FIELD: construction, particularly to product reinforced concrete articles, for instance floor slabs or framing structure panels for industrial and civil buildings, preferably for high-story ones.

SUBSTANCE: method for article production by serial layer pouring in retained form involves pouring the first fine concrete layer; leveling the mix in horizontal plane to provide the first layer surface flushing with the first bead of retained form; laying the first layer longitudinal reinforcement bars on the first bead; pouring heat-insulation layer of light-weight concrete in plane parallel to that of the first layer; leveling heat-insulation layer in horizontal plane so that heat-insulation layer surface is flush with the second retained form bead; laying the second layer longitudinal reinforcement bars on the second bead; pouring the second fine concrete layer on heat-insulation layer; leveling the mix in horizontal plane so that it is flush with retained form edge; performing simultaneous vibroforming of all layers and leaving the layers as they are for mix setting. During mix pouring retained form is put in rigid surface casing. To provide total concrete body air-tightness after mix leveling in horizontal plane and to provide mix flushing with upper retained form edge terminal retained form layer is laid in retained form. Form joints are sealed, for instance by welding, adhering, edge turning or any another well-known method.

EFFECT: improved heat-insulation properties, increased article service life and reliability.
