METHOD OF MANUFACTURE OF THE DOUBLE-LAYER REINFORCED CONCRETE PRODUCTS Russian patent published in 2006 - IPC B32B7/02 B28B11/24 

FIELD: building industry; methods of production of the construction products at the building industry works.

SUBSTANCE: the invention is pertaining to the field of building industry, in particular, to the method of production of the construction products at the building industry works and may be used for manufacture of the reinforced concrete, including the spatial structures with the heat-insulating layer. The technical result of the invention is reduction of the power input, improvement of the quality and expansion of list of products. The method of manufacture of double-layer reinforced concrete products includes the consecutive formation of the constructive and the heat-insulating layers of the reinforced concrete and its thermal treatment. The heat-insulating layer with the average density of 450-500 kg/m³ made out of the vermiculite-concrete mixture with flowability of 3-5 cm is molded by the vibrobeam with the simultaneous its reinforcement by the woven net in top level. After the structure achieves the plastic strength of 0.015-0.025 MPa, then begin the molding the constructive layer and conduct the thermal treatment by the method of the contact heating from the side of the heat-insulating layer.

EFFECT: the invention ensures reduction of the power input, improvement of the quality and expansion of list of products.
