MULTILAYER CONSTRUCTION PANEL Russian patent published in 2013 - IPC E04C2/38 

FIELD: construction.

SUBSTANCE: multilayer construction panel comprises an inner frame made in the form of a collapsible frame, made from galvanised perforated thermal profiles, made of lower and upper guides of a "П"-shaped profile with edge bends made towards one side, between which there are vertical ribs of a C-shaped profile arranged in a row at the distance from each other in longitudinal direction of the guides and rigidly connected to them by means of fastening elements, and also comprises a sheet lining, and in the inner cavity there is a non-structural insulant arranged, the external casing of the panel surface is made in the form of a fire-resistant air-permeable material arranged along its outer side, adjoining the vertical ribs of the C-shaped profile, and rigidly pressed with grating, made of rigidly connected to each other horizontal and vertical - shaped profiles, at the same time the grating is arranged aflush with the panel contour or as protruding, with a rigidly fixed finishing facade layer along the entire outer surface of the panel. In the panel there are window and/or door openings formed by "П"-shaped and C-shaped profiles. The protruding part of the grating is connected to a joint angle. Along the lower side of the panel there is a sealing gasket arranged. Along upper and/or lateral sides of the panel there is a compensating gasket. The fire-resistant air permeable material is represented by cement-magnesium slabs with perforation, or steel sheets with an anti-corrosion coating with perforation.

EFFECT: improved operational capabilities due to improved environmental capability, increased fire resistance, tightness, thermal properties, increased strength, reliability, durability and universality.
