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

FIELD: construction.

SUBSTANCE: invention relates to structures of suspended grated ceilings. Suspended grated ceiling includes multiple longitudinal and transverse interconnected shaped elements forming cells. According to the invention, all cells are made in the form of separate units, and the ceiling includes a plurality of profile interconnected elements forming a grated frame with windows, wherein length of shaped elements forming frame with openings exceeds length of shaped elements forming cells inserted into said openings by at least three times, but not more than ten times. All shaped elements of the frame and cells have the same profile and the same ends with projections, wherein lateral sides of all elements are furnished with closed grooves to interact with projections. Besides, on lateral sides of shaped elements forming the frame, there are open coaxially located stepped grooves, in which cell elements are installed. After assembling the shaped elements into the frame and cells, the ends of the shaped elements are bent inside the shaped element in different directions against the stop, which ensures reliability of fixation, excluding backlash, and thus increases the rigidity of the structure. For attachment of grated suspended ceiling on object at the middle of each longitudinal side of profile element there is a hole for suspension element.

EFFECT: increasing the rigidity of the suspended grated ceiling.
