FIELD: construction. ^ SUBSTANCE: floor panel at least on edges of two opposite sides is equipped with connection elements interacting between each other. Connecting elements are equipped with mechanical locking facilities that make a unit, which prevent opening of two connecting floor panels in direction perpendicular to appropriate edges and parallel to the lower surface of the connecting floor panels. ^ EFFECT: elimination of a gap between floor panels, which reduces possibility of dust and moisture ingress. ^ 21 cl, 25 dwg |
