CONSTRUCTION PANEL WITH COMPRESSED EDGES Russian patent published in 2009 - IPC E04F15/04 

FIELD: construction.

SUBSTANCE: scaffold board with locking system contains wood-fiber based core and surface layer. The surface layer is on the top of the core. The upper flat parts of surface layer constitute the covering surface and horizontal plane. The plane, which is perpendicular to horizontal plane lying next to external edge of the surface layer, is a vertical plane. The scaffold board has an edge section with surface lying under horizontal plane. The edge surface next to vertical plane is at some distance from the horizontal plane. That distance represents edge depth and exceeds the thickness of superficial layer. The scaffold surface and edge surface are implemented as a one-piece element made from the same material. Density of that core part which is under edge surface adjoining vertical plane and distanced vertically from edge surface, is more than that, adherent to core part located under scaffold surface adjoining the edge section at the same vertical distance from floor surface.

EFFECT: effective manufacturing process, improved design and resistant to galling.
