The invention relates to the multilayer building panels, in particular to the sandwich panels, and can be used in industrial and civil engineering construction for the manufacture of non-bearing heat-insulated fabricated quick-erection buildings and structures.The sandwich panel comprises two surface layers (1, 2), coupled with a central heat-insulating layer (3). The surface layers (1, 2) are made of fibrous concrete and the heat-insulating layer (3) is made of durable non-segregating heat-insulating material based on foamed polystyrene. On both surfaces of the heat-insulating layer (3) over the full length and width are made grooves (4). The surface layers (1, 2) are coupled with the heat-insulating layer (3) by means of stiffening ribs (5), formed when forming the surface layers (1, 2) by pouring with the mixture of fibrous concrete the surface of the heat-insulation material (3) with the filling of grooves (4). |
