ELEMENT OF MULTILAYER LIGHT-WEIGHT CONSTRUCTION PANEL, AND ITS MANUFACTURING METHOD Russian patent published in 2014 - IPC E04C2/38 E04B1/02 

FIELD: construction.

SUBSTANCE: invention relates to ground construction, and namely to enclosing structures of buildings and structures, and namely to wall panels, panels of coatings, floors, and can be used at erection of multi-storey buildings with a load-carrying reinforced-concrete, metal and wooden frame for large-scale and individual development, at reconstruction of buildings and secondary structures. An element of a multilayer light-weight construction panel includes an internal frame made in the form of a detachable steel frame containing perforated horizontal lower and upper guide elements, between which perforated vertical post elements are installed, which are located in a row in a longitudinal direction of guide elements and rigidly attached to them by means of fasteners and nodal connections, as well as an internal heat insulating layer and external and internal linings; with that, horizontal and vertical elements are made in the form of steel profiles, and profiles of vertical elements have a C-shaped section. Elements of the skeleton frame represent finished parts; with that, horizontal parts are made in the form of profiles of C-shaped section and also include horizontal connection straps; vertical and horizontal parts are connected and have additional bends of flanges of a trapezoid shape at connection points; perforation of parts is made in the form of transverse and longitudinal cut-outs for shaped metal, plate or wooden reinforcement elements of the framing, as well as in the form of process through cuts and guide drawn ends of holes for reinforcement of a connection node with additional stiffeners. The internal heat insulating layer is three-layered and made in the form of two layers of cellulose warmth-keeping material, between which an internal temperature and moisture control insert with internal vertical air chambers, drain channels and condensate collecting channels, which are connected to each other into a common system, is located; inner and outer linings are composite and made in the form of parts with internal fish joints and structural attachment nodes; to outer surface of the outer lining there attached are external fish joints and horizontal U-shaped profiles, which are covered with an external heat insulating layer. Besides, a manufacturing method of such an element is described.

EFFECT: reduction of labour intensity and power consumption for manufacture and erection owing to reducing the number of process operations related to humid processes, machines and mechanisms, which provides the possibility of reducing design and construction limits, with increased fire resistance, sound insulation and heat insulation indices; reduction of material consumption and power consumption for construction.
