FIELD: construction.SUBSTANCE: invention relates to the production of construction materials and products, in particular for the erection of protecting self-bearing walls in a frame low-height construction and in the construction of civil or industrial facilities using the frame technology, and also for decorative-and-thermal-insulation cladding of facades of buildings. The multilayered structural panel implemented in the form of a monoblock, including: a layer from a heat-insulating material with open porosity selected from the group comprising foam, fibre, granulated compositions and their combinations; one or two protecting layers from concrete; one or two transitional layers on the boundary of the surface of the heat-insulation layer formed during hardening of the concrete mix and providing seamless joining of the layers. For the protecting layer or layers fine-grained fibre concrete, reinforced by nonmetallic fibre, for example polypropylene, glass, with plasticising, water repellents and curing accelerators, is used. For the formation of the transitional layer or layers redispersible powders providing the adhesion of concrete to various materials are added to the concrete mix, on the lateral sides of the plate of the heat-insulation layer along the perimeter groove is cut out. Also industrial equipment and a method for the production of the panel are described.EFFECT: decrease of labour input at production of multilayered structural panels.13 cl, 8 dwg |
