FIELD: construction.
SUBSTANCE: multilayer wall panel with one or two window openings includes outer and inner layers from reinforced concrete, situated between them a layer of thermal insulating material and elements joining the layers made in the shapre of discrete concrete connections uniformly distributed about the panel. The thermal insulating material is foam polystyrene placed between the outer and inner layers with an open exit at least at three side ends of the panel and consists of separate fixed and butt-packed elements. Between the inner layer of the reinforced concrete and the thermal insulating material there is an insulating layer in the form of foil or plastic film or metal-coated plastic film. Multilayer wall panel contains four locking keys situated at its ends. The specified discrete reinforced concrete connections binding the outer and the inner layers of the reinforced concrete function at the same time as fixators for the elements of the thermal insulation material and are placed in the holes performed in the insulating layer and the thermal insulating material. The discrete reinforced concrete connections have rectangular cross section, at that the bigger part of the specified rectangular has at least two discrete reinforced concrete connections, oriented in the direction perpendicular to the bigger side of the rectangular of the rest discrete reinforced concrete connections and in parallel to the smaller side of the multilayer wall panel. The reinforcing part of each of the specified discrete reinforced concrete connections is made in the form of framework from two loops connected in-between by parallel polls. At that planes of the polls are in parallel to the existing side end surfaces of the panel, and the polls themselves are situated along the specified side end surfaces. Rectangular wall panel is described.
EFFECT: increase of durability and performance properties.
