CASSETTE MODULAR SUSPENDED CEILING Russian patent published in 2023 - IPC E04B9/04 E04B1/84 

FIELD: construction.

SUBSTANCE: elements of prefabricated suspended ceilings with noise reduction properties. A modular suspended ceiling cassette is proposed, which has front, back and lateral sides and includes a frame, a sound-absorbing panel and at least one fastener. The cassette frame includes two load-bearing and two non-load-bearing sidewalls, which together form the sides of the cassette and are located essentially in the form of a straight quadrangular prism, with the load-bearing sidewalls being parallel to each other and spaced apart at a distance determined by the location of the suspended ceiling guides. Each of these load-bearing sidewalls is equipped with at least one engagement means for detachable fastening into the suspended ceiling guide. On the front side of the cassette, each of the sidewalls is equipped with a protrusion made integral with the sidewalls and perpendicular to the sidewalls in the direction of the prism axis to form a stop for the sound-absorbing panel. The sound-absorbing panel is placed inside the frame with emphasis on the protrusions and is secured on the back side of the cassette with at least one lock. The lock includes a clamp for fixing the position of the sound-absorbing panel and two flanges made perpendicular to the clamp. These two flanges are permanently connected to the corresponding sidewalls of the frame.

EFFECT: improvement of the acoustic characteristics of the premises; ensuring the possibility of repeated dismantling of the cassette while maintaining its strength characteristics; reducing the resource consumption of the product; ensuring the possibility of installing the cassette into existing suspended ceiling systems; ensuring the possibility of using suspended ceiling cassettes in premises of arbitrary shape.
