Technical field

The technical solution concerns railroad crossing, especially with concrete level crossing panels, for paving of railway gratings of railway crossings, railway crossings, city rails and the like.

BACKGROUND OF THE INVENTION

Known paving of rails, in particular level railway crossings and crossings, consisting of special paving slabs fastened to wooden sleepers by screw connections, or these paving slabs are fastened by neoprene wedges in the coupling chambers of rails. The disadvantage of these solutions is poor access to rail fasteners and laborious and hence time-consuming dismantling and assembly of rail grating paving. In the structures laying the paving slabs on sleepers, the rail fasteners are subject to considerable stress, which results in the rails being released from the sleepers, which leads to the disintegration of the geometrical position of the rail.

Some other constructions use paving slabs made of technical rubber, placed on specially prepared subsoil or directly on individual sleepers of the rail grate. The different alignment of the track and said subsoil causes later undesirable relative height deviations of the rails and paving slabs and the leveling of the level crossing. Also, the varying extensibility of the technical rubber floorboards, depending on the ambient temperature, causes destruction of the level crossing of the railway crossing elements with all the associated negative consequences.

One of the known solutions, in which said deficiencies have been partially eliminated, is that the paving slabs are laid on the rails of the rails by means of opposing beams fixed to the paving slabs by means of hinges, with each of the paving slabs and the beam, rail foot and beam. elastic pads. The advantage of this placement of the paving slabs is the uniform transmission of dynamic forces to the rail substructure, satisfying the positioning of the paving slabs outside and inside the grating, easy and quick assembly and disassembly of the whole paving. This also ensures good aeration and drainage of the rail substructure and good access to the rail fasteners. Flexible mounting captures and reduces impact from heavy road vehicle wheels. The solution of electrical insulation in the joint joint eliminated the problems of electrical resistance. This solution further enabled the desired continuous operation of the track machinery to be maintained for track subsoil and the like to be interrupted. However, these advantages are associated with the relatively higher cost of the individual floor slabs and the low corrosion resistance of the beams and their joints.

The essence of the technical solution

The aim of the technical solution is to create a railway crossing, especially with concrete crossing panels, equipped with at least one standardized longitudinal recesses at the bottom, which would have easy assembly / disassembly technology with a high degree of dorectification of the position level of concrete crossing panels within their crossing. furthermore, it exhibited longevity, material availability and simplicity associated with the production of the necessary elements, said object being achieved according to the invention by having a system of backrests for the transit panels, each of which consists of two side walls mutually connected by at least one crossbeam connected to a saddle for straddling the rail sleepers near the rail fixtures, the side walls of the backrests in this area are provided with vertical edges for contact with the rail edge and nosepiece with the projections for bearing on the rail heels and in their recessing upper portions, then with supporting projections for interaction with the shape recesses in the passage panels with the transition to the bearing surface on the crossbeam concurrently covering either their corpus and / or in combination with additional supports in a given zone relative to the desired level of the passage panels.

Advantageously, according to the invention, it is advantageous in rail crossing that each of the supports is provided at the points of contact with the concrete passage panel with a flexible coating, in particular a rubber or plastic coating, technologically easy to apply, preventing both penetrating corrosion effects and dielectrics against unwanted penetration. electric currents.

For curved sections of the track, when the mutual spacing of the rails of the atom is slightly increased, it is necessary to adjust the horizontal position of the individual concrete passage panels, according to the technical solution, that the support projections for these concrete passage panels are formed on shims fastened by a clamping joint. on the sides of the backrests at least in their longitudinal direction.

SK 7749 Υ1

Advantageously, according to the invention it appears that the pads with support projections as well as the pads are made of durable plastic.

For the mutual stability of the combination of the backrests with the supports, according to the technical solution it seems advantageous that the supports are provided with transverse grooves to engage with the bottom of the support crossmember.

For this purpose, the shims 17 are provided with a longitudinal open groove 19 (Figure 9). The shims 17 with the support projections 12 as well as the washers 15 are made of, for example, a durable plastic.
