COVER FROM POLYMER MATERIAL FOR DRAINAGE GUTTER Russian patent published in 2015 - IPC E01C11/22 

FIELD: construction.

SUBSTANCE: cover from polymer material for a drainage gutter having flat support sites, a convex middle part and longitudinal ribs-thrusts for fixation relative to the gutter. The cover is made from polymer composite material by the method of pultrusion or vacuum infusion, reinforcing fibres of the polymer composite material are mainly aligned across the longitudinal axis of the cover. The convex middle part is made in the form of a coupling of two planes at the angle, the longitudinal ribs-thrusts are made in the form of edges of flat support sites bent down. The cover is equipped with fixtures for fixation on gutters, which may be made, for instance, in the form of transverse slots arranged in support sites for installation of fixation bolts in them to gutters.

EFFECT: strength and durability of gutter covers, manufacturability of their manufacturing, inconvenience of walking of pedestrians on them.
