SLAB WITH PROJECTIONS FOR ISOLATING ROADBED SECTION Russian patent published in 2018 - IPC E01C5/06 

FIELD: construction.

SUBSTANCE: slab with projections for isolating a roadbed section is made monolithically with two limiting projections symmetrical with respect to the transverse axis. At the projections, warning stakes are rigidly mounted, on the surface of which light-reflecting thin-layer coatings are applied. Two hoisting openings symmetrical with respect to the transverse axis are made in the slab. At opposite end slab sides, docking units in the form of alternating docking projections on one of them and docking recesses corresponding to them in shape on the other are made. The design features of the slab with projections for isolating a roadbed section are reflected not only in the characteristic of the units and their constructive interconnections included therein, but also through, inter alia, the structural characteristics of the basic units of the object to be patented, using their substantial geometrical parameters.

EFFECT: increased mechanical strength of a slab with projections while reducing its production cost and increasing the effectiveness of isolating a roadbed section.
