BARRIER FENCE OF MOTOR ROAD Russian patent published in 2003 - IPC

FIELD: various structures for roadside construction. SUBSTANCE: barrier fence for motor road includes posts coming in the form of set of longitudinal unidirectional flexible bars oriented along axis of posts fastened by means of at least one group of inclined unidirectional flexible bars, placed at angle from 30 to 90 degrees with reference to axis of post and embracing all or part of longitudinal flexible bars. All flexible bars are united in at least one longitudinal profile by arrangement in compact polymer medium. Volume relation of longitudinal and inclined bars lies in limits from 50:1 to 1:1 with volume relation of all flexible bars to compact medium from 1:1 to 1: 0.2 and relation of total area of cross-sections of all longitudinal bars to total area of sections of all inclined bars from 15:1 to 1:15. EFFECT: development of structure of post of barrier fence demonstrating increased resistance to outside corrosive actions in wide spectrum of damping characteristics in process of elastic deformation up to destruction. 24 cl, 4 dwg
