DEVICE FOR FIXATION OF FACING ELEMENT IN INTERFACE OF TWO SURFACES Russian patent published in 2019 - IPC E04F13/21 E04F19/04 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to fasteners of facing elements (14) in place of transition between two surfaces (3), (12) (for example, floor and wall), and can be used for concealed fastening of skirtboard, decorative profiles, facing planks and other similar elements having fastening slots. Device is made in the form of angular profile from sheet metal material. Profile comprises base (2); wall (1) provided with at least one fastening hole (5); and upper fastening protrusion (8) for placement in upper attachment slot (11) of facing element (4). Ledge is formed by bending of upper end of wall (1) and includes part protruding inward from wall (9), which changes into upper arch-shaped lug (10). Tab runs in direction from base (2). Device also comprises lower fastening protrusion (13) for arrangement of facing element (4) in lower mounting slot (14). Projection includes at least one lower tab (15). Tab is formed by bend of base end along curve of line in direction of wall (1). End part (16) of lower tab is bent in reverse direction. Ratio of height (H1) of lower tab (15) to height (H2) of upper tab (10) is from 1.5 to 3.

EFFECT: increased rigidity of facing of large-width facing element and reliability of its retention, simplified assembly.
