FIELD: construction.
SUBSTANCE: invention relates to construction, namely to multi-layer building elements containing a heat-insulating layer. Multilayer building element includes external elements and a heat-insulating layer placed between them. Herewith the upper and the lower surfaces of the external elements of the multilayer building element are formed with a longitudinal slot along the entire external element. Multilayer building element further comprises longitudinal connecting elements entering the slots of the upper and the lower surfaces of the external elements of the multilayer building element. Multilayered building element is made with the possibility of both horizontal and vertical laying. In the heat-insulating layer, technological slots are made for electrical wiring guides. Technological line for producing the multilayer building element and a method for manufacturing the multilayer building element are also described.
EFFECT: technical result is creating a multilayered building element that is simple and convenient to be combined in a construction that gives a minimal shrinkage with the possibility of using a multilayer building element for erecting walls of bearing, internal partitions, floors and ceilings, as well as manufacturing finished walls with all technological holes by gluing and screeding during production; a high-performance production line for producing the multilayer building element using known equipment, with low energy consumption, as well as providing the possibility of supplying external elements vertically oriented, as well as a continuous and low-cost way of manufacturing the multilayer building element.
