FIELD: construction.SUBSTANCE: for spacing in different cases of use with facing flange facing profile for flooring is made at least with one catch at lower part of the facing flange that divides the facing flange into two lips and at least with one bending groove parallel to profile axis at lower side. At least one, preferably having different width of facing flange lip; at that at lower side of facing flange at least one bending groove is envisaged that passes in parallel to profile axis and divides respective lip of the flange into sections; at that facing flange at its outer side opposite to the catch has a coating forming membranous hinge at bending groove area and both lip sections at two sides of bending groove are supported by each other by hinge stopper.EFFECT: increasing rigidity of the facing flange at bending grove section, possibility of spacing in different cases of use observing the permitted load for unbroken facing profile, increasing diversity of shapes for facing profile and materials for facing flange.17 cl, 14 dwg |
