METHOD FOR LAMINATED BUILDING PANEL 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, civil and other building erection.

SUBSTANCE: method for article production mainly of rigid cement mixes and including at least one heat-insulation layer of light-weight concrete and at least two fine concrete layers involves pouring the first fine concrete layer in the first form part; leveling the mix in horizontal plane to provide the first layer surface flushing with form edge; covering the first layer surface with glass tissue layer; adding the second form part in upward form direction; pouring light-weight concrete layer so that light-weight concrete layer is parallel to the first one; covering light-weight concrete layer surface with glass tissue layer; adding the third form part in upward direction; performing simultaneous vibroforming of all layers and leaving the layers as they are for mix setting; stripping the form from ready panel.

EFFECT: improved heat-insulation properties, increased uniformity of article thickness along with increased article strength necessary to erect high buildings or buildings having different number of stories without the use of additional structural members.
