METHOD FOR FORMING CONTACT LAYERS OF MULTILAYER ENCLOSING STRUCTURES Russian patent published in 2021 - IPC B32B13/00 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to a technology for manufacturing multilayer building products with a heat-insulating layer of lightweight concrete, and relates to a method for forming contact layers of multilayer enclosing structures. The method includes sequential laying of the first structural layer of the product, laying the heat-insulating layer and laying the second structural layer and vibration compaction of the layers, while vibration compaction of the layers is carried out for each layer separately with the formation in the contact layer of mutual penetration of concrete aggregates of the layers into the monolithic cement matrix of the structure.

EFFECT: invention provides the formation over the entire contact surface of a continuous monolithic bond between the outer and inner layers of a multilayer building structure, strengthened by mutual penetration of aggregates into the thickness of adjacent concrete layers with the formation of a single cement matrix.
