BUILDING PANEL (VARIANTS) Russian patent published in 2005 - IPC

FIELD: building units, particularly sandwich panels used to erect low buildings and structures, to produce cooling or freezing chambers (containers) and as heat-insulation.

SUBSTANCE: building panel is adapted to be connected to building structure or to identical building panel by means of fixing members or fastening members or with the use of connection means, which connect the panel to identical one. Panel comprises outer and/or inner coating connected to heat-insulation layer made of polystyrene foam material having 10-50 kg/m³ density. Elastic closed-cell foamed polyethylene-based material with 20-70 kg/m³ density is used as outer and/or inner coating. Heat-insulation layer is connected to the coating by phenol-containing adhesive. The adhesive is applied by aerosol spraying thereof on coating surface to be connected so that adhesive surface plastic foam layer is created as a result of the layers connection, wherein the surface plastic foam layer is used a component of the adhesive. End walls of heat-insulation layer are framed with profile made of aluminum or steel sheets. Coating at panel edges is applied on top of side surfaces of the profile. The second panel embodiment is also disclosed.

EFFECT: improved heat-insulation properties, simplified structure, reduced cost, increased heat-insulation reliability, extended range of panel variants application and reduced panel weight.
