BARRIER GUARD FOR HIGHWAYS AND OVERPASSES Russian patent published in 2016 - IPC E01F15/04 

FIELD: roads.

SUBSTANCE: invention relates to road protections of motor roads and may be used for safety during movement of motor transport on complex, radius sections of roads and bridge passes. Proposed barrier guard for dressing and bridge transitions, including vertical posts and attached to them along the road longitudinal beams, posts are made of bent profile or u-section of profile c-shaped section, and lengthwise beams are made of wave-like profile, wherein the longitudinal beams are attached to posts in one or more tiers for single or double-sided enclosure directly through cantilever-shock absorbers with the help of fasteners. Besides, ends of lengthwise beams on radius turns dressing are radial external or internal bearing elements, and the ends of two-sided enclosures are fastened to each other with-shaped bearing elements, the wavy profile radius of external and internal, as well as c-shaped bearing elements is identical to profile of the longitudinal beams and is made double-wave ratio wave height h to its length L as 1:2. Lengthwise beams, radial external and internal bearing elements of both tiers are provided with light-reflecting elements.

EFFECT: technical result is upgraded reliability of structure, reduced damages of motor vehicles.
