CONCRETE DRAINAGE AERATION TRAY Russian patent published in 2024 - IPC E03F1/00 E01C11/22 

FIELD: construction.

SUBSTANCE: invention relates to production of concrete products, in particular to arrangement of aeration floor with drainage trays for collection and discharge of settling liquid. Aeration tray is made in the form of a monolithic concrete block (1), the outer surface of which is made in the form of a polyhedral prism, and section of internal through hole (3) is made in the form of a body of revolution. On the end sides of the concrete block there are butt joints for interfacing the blocks to each other. On one end face, butt joint is made in form of support-guide fold (4), and on the opposite side – in the form of a bushing connection unit with integrated sealing gasket (6) in mounting hole (5) of unit (1). On upper face (2) of the prism, through holes (7) are formed, into which nozzles (8) are inserted, rod (11) with through central hole (10) of nozzle (8) is oriented inside monolithic unit (1), and head (9) of nozzle (8) is recessed relative to upper surface of face (2) of prism.

EFFECT: development of aeration tray with high operational characteristics, simplification and acceleration of installation process, increase of durability during operation of aeration floor due to provision of repairability.
