SUSPENDED LATTICE CEILING Russian patent published in 2025 - IPC E04B9/34 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to devices of suspended lattice ceilings. Suspended lattice ceiling includes grid frame of shaped elements forming cells, panels installed in cells on front side of ceiling, and panel fixing elements. According to invention panel fixing elements are made integral with panels, wherein all four sides of each panel are bent towards its rear side by the amount required for the orientation of the panel in the frame cell, and with an angle of inclination, as well as a profile, corresponding to the angle of inclination and profile of the side of the profile element of the frame with which they are mated. Profile elements in section have form of isosceles angle, or isosceles trapezium, or rectangle. Besides, profile elements can have shape of 2nd-order curve section, for example, hyperbola, parabola, ellipse or circle section. Panel is made of sheet metal or plastic, wherein panels have rectangular shape. On each bent side of panel at least two fixing elements are located. Each fixing element is made in the form of a rectangular projection on the continuation of the panel side bent inside and is bent to the outer side from that side of the panel, at the same time the distance between the bent ends of the projections exceeds the size of the frame cell, into which the panel is inserted.

EFFECT: simplification of the design of a suspended lattice ceiling, due to the fact that the panel fixing elements are made as a single unit with the panels.
