Abstract

The design is used in the transport construction to create the paved road and pedestrian traffic on a tram or railroad track. The location of the roadway cover relative to the rail track can be adjusted. The cover consists of end (1, 5) and middle (3) reinforced concrete panels located respectively outside and between the rails (2, 9) and by means of adjusting and fixing the panels (1, 3, 5) to the rails and between them. In a vertical plane, the panels (1, 3, 5) are adjusted by a plurality of thin and thick elastic pads (8) placed under the panels, and in the horizontal plane the panels (1, 3, 5) (1, 3, 5) threaded sleeves (6) or by means of pins (14) and metal connections (13, 15, 16) fastened to the rails (2, 9). The side walls of the panels (1, 3, 5) are sloping in the lower part to provide space for the rails of the rails with the base and for the transverse joints of the rail panels. The construction of the road cover can be applied to all types of rails, , sleepers or foundations.

Description

(54) RAILWAY ROAD CONSTRUCTION

Technical field

The invention relates to the field of transport construction and is used, if necessary, for road pavement on a single level in order to create a road on it for cars and pedestrians. When the coverage on the rail road is only within the boundaries of a crossing street or road, then it forms a crossing or path. If it is the entire length, it acts as a street or playground floor. The invention can be applied to railway, tram and subway tracks.

BACKGROUND OF THE INVENTION

[0004] A pavement construction is known for a rail track of crossing panels. It consists of central and end-to-track reinforced concrete panels, on which the longitudinal walls are formed by concreted rails - inverted if the wall is against the track rails and straight when exterior.

The position of the panels relative to the track can be adjusted in the horizontal and vertical planes and then fixed by tightening the bolts. Additional pads, initially plastic and arranged according to the scheme, predetermine the support of the panels in working condition to be done only on the sleepers. Adjustment and fixing of the location of the panels against the covered track is accomplished by means of additional devices that are mounted on the rails in the intertransverse spaces. The devices consist of a metal L-shaped connecting plate, which is mounted parallel to the sleepers and is fastened to the underside of the rail heel by two bolts, two rail clips and two nuts. The two bolts around the rail are of such length that they can be attached to them. fasten with a second nut and L-shaped metal clamps to secure the panels.

The sequence of the installation of the coating and the adjustment of its location include the installation in the middle position of the connecting strips to the heels of the rails through the clamps, the long bolts and the first nut. Template mounting (different thickness) washers on the plates - one in the track for the central panel and two outside for the edge panels. Laying of additional supporting pads. Installation of panels. Mounting and tightening of L-shaped metal brackets for fixing panels, which are three pieces of connecting plate and have precisely defined dimensions to maintain the overall distances [1].

In the known solution, the adjusting and fixing means are composed of many elements and are included in the rail fasteners.

SUMMARY OF THE INVENTION

The problems to be solved by the invention are to provide a rail track structure in which the means of adjustment and stabilization have a simplified construction and universal application, to provide opportunities for covering existing tracks, regardless of their type. In the case of new construction, any restrictions on the construction of the rail track should be removed, as a result of the fact that they must be covered.

The track structure for a track according to the invention comprises from one or more adjacent tracks of rails on a beam or other base covered with reinforced concrete panels. The shape of the panels in relation to the rails depends on their shape and they are: medium - in the track; extreme - outside the track and towards the road; intermediate - between tracks when they are two or more.

The means for adjusting and stabilizing the panels in the vertical plane are made up of different thicknesses and a number of pads that are laid on the sleepers or the base of the rails.

The means for adjusting and stabilizing the panels in the horizontal plane are made up of threaded bushes embedded in the walls parallel to the rails. In the sleeves are threaded studs with nuts. In transport and installation condition, the bushes are wound in the panels and together with the nuts they serve as hooks, and in the operating position and with the nuts removed, the studs are developed to the extent necessary so that they reach the rails. The studs have a wrench-shaped section that is accessible in all states of the panels.

The means of overall stabilization of the road surface consists of pins connecting the panels in the longitudinal direction by means of shaped sockets therein and cross-links between the rails which have holes for the passage of the pins. The ends of the cross-links in contact with the rails are bent and bolted to them.

The walls of the panels parallel to the rails are slanted so that they do not affect their fastenings, and depressions are formed in the perpendicular walls beneath their upper parts so that transverse connections are placed in the formed spaces. The upper edges of the panels are formed by metal frames.

The advantage of the construction over the known is that the coating is applicable to all rail track structures, including those with inaccessible bottom surface of the rail heels along the entire covered length. The loads from the vehicles to the sleepers and the ground base are transmitted according to the same scheme as the rolling stock on the rails, as a result of which the work of the structural elements and the layers below them does not change. It is possible to repair the cover, adjust its location by axle and level, as well as replace it without affecting the construction of the track, including without stopping its movement.

Examples of implementation

The invention is explained in more detail by way of an exemplary embodiment of the road surface construction shown in Figures 1 to 4.

The track structure for the track according to the invention comprises one or more adjacent tracks of rails 2, 9 on sleepers or other base, covered with reinforced concrete panels 13, 5. They are middle 3 located in the track; extreme 5 outside the track and into the road; intermediate 1 between tracks when they are two or more.

The means for adjusting and stabilizing the panels 1, 3, 5 in the vertical plane consist of different thicknesses and a number of pads 8, which are laid on the sleepers or the base of the rails 2, 9.

The means for adjusting and stabilizing the panels in the horizontal plane, shown in detail in FIGS. 5 and 8, consist of threaded bushings 6 embedded in the walls parallel to the rails. In the sleeves 6, the studs 4 are threaded with nuts 19. In the tran3 sports and mounting condition, the sleeves 6 are wound in the panels and together with the nuts 19 they serve as hooks, and in the operational position and with the nuts 19 removed, the studs 4 are developed to the required degree, 5 to touch the rails 2.9. The studs 4 have a section formed by a hexagonal or square section with a wrench, which section is accessible in all states of the panels. 10

The means for general pavement stabilization shown in detail in FIGS. 6 and 7 consist of pins 14 connecting the panels in the longitudinal direction through shaped sockets therein and cross links 13, 15, 16 15 to the rails having openings for crossing the pins 14. The ends of the cross-links 13, 15, 16 in contact with the rails 2.9 are bent and bolted 18 to them. 20

The walls of the panels parallel to the rails 2,9 are beveled so that they do not affect their fastenings 11, and depressions are formed in the perpendicular walls below their upper parts so that the cross-sections 13 are arranged in the shaped spaces 25, 15, 16. The upper edges of panels 1, 3, 5 are formed by metal frames 20.

Application of the invention

The construction according to the invention can be used for level crossings, as well as for complete street or industrial coverage of existing or newly constructed railways for rail, tram, subway and mining.
