FIELD: drainage devices.
SUBSTANCE: tray system (1) contains at least one frame block (10), at least one cover block (20) and at least one first damping element (14). The frame block (10) has at least one receiving area (12) intended for mounting the cover block (20) and formed by at least three side walls (12.1; 12.2; 12.3; 12.4; 12.5). The first damping element (14) is made for its mounting between the frame block (10) and the cover block (20) so as to ensure the placement of the cover block (20) in the frame block (10) with damping of the cover block (20) in at least three spatial directions. The cover block (20) is made in combination with at least one movable fastener (24) capable of entering the receiving area (12) of the frame block (10) for at least temporary engagement therein.
EFFECT: tray system is provided which is easy to manufacture, which provides an optimized support for the grating or cover unit, which allows easy on-site installation and which at the same time allows for easy maintenance.
