HOLDING BARRIER RAILING FOR HIGHWAYS Russian patent published in 2016 - IPC E01F15/04 

FIELD: roads.

SUBSTANCE: invention relates to road guards. Barrier railing comprises vertical posts and horizontal lengthwise beams, arranged along road, which are fixed to vertical posts through console support and cantilever-shock absorbers. Posts are made of double tee. Lengthwise beams are asymmetric C-shaped profile with additional flanges, bent inside section, where reduction (reduction of overall dimensions of cross-section profile) is performed at one end of beams, so that when mounting structures, lengthwise asymmetric C-shaped beams are inserted one into another. Lengthwise beams are attached to posts in one or more tiers directly via cantilever support or cantilever-shock absorbers by metal group, which is a T-shaped pin with an elastic retainer bushing, T-shaped pin is made so that it passes through longitudinal slot of asymmetric section of beam, being in horizontal position, then, expanded by 90° relative to axis of pin and yielding in reverse side, rests against inner flanges of section of beam and due to bends on T-shaped link does not allow not only go outside and but turn about its axis. Thus T-shaped pin can be directly installed in any place of section of beam, and not make it with side, which saves time when assembling structures guard rail, and also enables to install posts with any required spacing. After installation, in the required place of section of beam of T-shaped pins, its position is fixed by means of located thereon an elastic locking sleeve. Longitudinal sections of beam of one tier are connected to each other by seating into each other, by means of through-bolts via spacer inserts, providing required compression between connected surfaces of sections of beams without deformation thereof at moment of tightening bolts.

EFFECT: technical result is increase in guard rail, improved workplace injury prevention of guard railing structures and improved repairability.
