DRAINAGE SUSPENDED TRAY MADE OF POLYMERIC COMPOSITE MATERIALS (VERSIONS) Russian patent published in 2015 - IPC E01D19/08 

FIELD: construction.

SUBSTANCE: according to all options of the proposed solution, the drainage suspended tray made of polymeric composite materials, having a concave bottom, flat walls angled outward, in the top part of which there are folds outward, unlike the prototype is equipped with transverse struts fixed on the wall folds, the end parts of the tray have bottom and wall folds outward, made in the form of flange with holes made therein for mounting, the upper sections of the tray walls in the flange area have thickenings with additional layers of filler, holes are made in the thickenings through which the suspended brackets of suspension made of polymeric composite materials, provided with transverse struts, are mounted on the trays. In order to use the tray as the initial or end, the end plug - shielding plate with holes, corresponding to the mounting holes of the tray flange, can be fixed on one of the edges of tray on the flange. End tray has a hole with drain tube installed in it, and tray-tee has a branch section located at an angle with the straight section.

EFFECT: providing rigidity of trays, ensuring integrity of their joints and prevention of their lock release, unification of elements of drainage systems.
