SET OF PROFILES Russian patent published in 2023 - IPC E04B9/22 

FIELD: construction.

SUBSTANCE: technical solution relates to fixation devices, fastening plasterboard sheets (PBS) to a permanent structure, for example, to the walls of a room. A set of profiles, including a stationary profile having an open rectangular section, with a bottom and mirror-symmetrical shelves with counter-directed cornices at the ends of the shelves, oriented parallel to the bottom at the ends of the side shelves, and a movable profile having a means of fixing gypsum boards, with attached to the gypsum board fixation means with a bracket for placement inside a stationary open profile, and the bracket is made of two arms, proximal and distal with a bend of 90° between them; on the distal arm of the bracket, there are mirror-symmetrical locking and thrust ribs, the distance between the locking and thrust ribs of the movable profile bracket is less than the distance between the bottom and the mirror-symmetrical cornices of the stationary profile, and the distance between the cornices of the stationary profile is greater than the thickness of the distal part of the cornice. The joining element can be used to join adjacent profile elements to obtain an arbitrary length. The backlight stop is used to simplify the fixation of the LED strip.

EFFECT: improved installation conditions, expanded range of continuous changes in the geometric dimensions of the wall, length or height, which leads to no cracks at the junction of the ceiling and wall, as well as creating a “floating ceiling” (or wall) effect.
