Description

The utility model relates to transport construction and can be used in the construction and repair of tram or railway crossings at the places of their intersection with the highway.

Known design of the flooring for crossing the rail track (see, for example, the description of the patent of the Russian Federation for the invention No. 2332536 in the class E01C9 / 04 with priority from 05.24.2006). The flooring for crossing the rail track contains elements made of elastomeric materials laid in the transverse direction of the rail and on both sides of the rail spaces, with obtaining at the level of the upper edge of the rails a surface for the movement of motor vehicles. The flooring elements are combined with each other in a module, each of which contains external and internal plates with grooves and, accordingly, external and internal liners and gaskets for installation on reinforced concrete sleepers, or the mentioned external gaskets turned upside down for installation on wooden sleepers, while the internal plates between themselves and the outer plates are interconnected by means of a tongue-and-groove connection of the end surfaces or by means of connecting plates.

The tongue-and-groove system can function normally only when the plates are firmly adjacent to each other. Often during the operation of moving on the way, the end fixing of the flooring cannot keep the plates in their places and they start between them, gaps appear. At the same time, the spike-groove system, due to its conical shape, stops working and steps appear between adjacent plates that impair the smooth passage of wheeled vehicles through the level crossing.

The construction of the railway crossing is known (see, for example, the description of the certificate of the Russian Federation for utility model No. 7418 in class Е01С 9/04 with priority dated 10/08/1997). In the construction of this crossing, adjacent sections of the plates are connected to each other by means of end protrusions and depressions and have concentric through holes on the end surfaces for fastening the sections with fasteners. As fasteners, rods are used located in the holes of the plate sections and connected to each other by threaded connections, moreover, threads are made at one end of each rod, a nut for this thread is made at the opposite end of the rod, and a cylinder with a central hole is pressed onto the end of this end Full construction.

The disadvantages of this design include the many-sided system of the end screed plates and the impossibility of the final screed already assembled design.

A known construction of a rail crossing (see, for example, the description of a patent of the Russian Federation for an invention No. 2450098 in class Е01С 9/04 with priority dated July 26, 2010). The railroad crossing contains a base laid on the base of the sleepers with rails fixed on them, rubber panels located on the sleepers on both sides of each rail, connected by longitudinal ties in the form of metal ties, inside of which are placed rods connected at the ends of the crossing with rails and transverse ties made in the form of metal double tee, the shelves of which are included in the grooves formed in the end faces of the panels, connecting the panels together; in addition, through holes were made in the walls of the I-beams, and open channels were formed in the middle part of the rubber panels along the entire length of the rubber panels, while the metal ties pass through the through holes in the walls of the I-beams and in the channels formed in the rubber panels, linking the panels in the longitudinal direction.

Due to the use of an end connection in this design in which metal I-beams are placed in the grooves of the panels, connecting the panels between, and not the tongue-and-groove joints, the floor panels, even with screed, will not work as a single unit and, accordingly, qualitatively redistribute the load.

A known construction of a coating plate for tram and railroad crossings (see, for example, the description of the Russian Federation certificate for utility model No. 11801 according to class E01C 9/04 with priority dated July 1, 1999). At the coating plate for tram and railroad crossings, the surface layer is made of wear-resistant rubber based on polyisoprene and polybutadiene rubbers with profile elements made on its surface to increase the adhesion of the plate to the tires of a moving tool in the form of two groups of cylindrical elements protruding above the plate surface by 3-6 mm , one group of which has a diameter of 35-45 mm and the second group has a diameter of 15-25 mm, and elements of smaller diameter are evenly spaced between the elements Tammy larger diameter, the total surface area of the projecting cylindrical elements is 75,0-90,0% of the surface area of the plate.

As practice has shown, the cylindrical protrusions of the plate do not provide optimal adhesion of the vehicle wheels to its surface.

The utility model is aimed at improving the system of fastening plates between each other and improving the quality of adhesion of the wheels of the vehicle to the surface of the leveling plates.

For this purpose, a deck construction is proposed for moving across a rail track containing internal and external plates of elastomeric materials, laid respectively in the rail and on both sides of the rail spaces, with obtaining at the level of the upper edge of the rails a surface for the movement of vehicles, the plates being connected by longitudinal bonds in the form of couplers, inside of which fastening fittings are placed, connected at the ends of the level crossing with rails. The joining of the inner plates to each other and the outer plates to each other is carried out by means of a tongue-and-groove connection of the end surfaces, and when connecting adjacent plates to the spike, before placing it in the groove, the channel is put on and inserted with it into the groove of the adjacent plate. Channel bars allow to give plates additional rigidity. The channels of the inner plates are made with two holes for placement of the couplers of the system of fastening the plates between them, and the channels of the external plates with one hole. The inner plate is made with one mounting channel, two channels for installing screeds and recesses for placing intermediate rail fasteners in them, and the outer plate is made with one channel for installing screeds and recesses for placing intermediate rail fasteners in them. The mounting channel allows you to bend the inner plate during installation to establish it under the rail head. The lower surface of the interior flooring plates is molded in such a way that it repeats the surface of the sleepers at the place of laying on it. The top surface of the plate is a flat corrugated surface that provides the necessary coefficient of adhesion between the tires of the vehicle and the deck. The outer slabs are based on one part of the sleepers, and the other on the concrete corners, which in turn are based on distribution boards. The plates can be made in such a way that the width of the outer plate will be twice as large as the width of the inner plate. Each pair of inner plates is attracted by two ties, respectively, to already installed inner plates, and each outer plate is attracted by one tie, respectively, to already installed outer plates. After mounting all the couplers, a hole is formed that passes through the bodies of all the connectors, into which the mounting fittings are placed. On both sides of the crossing, the fittings are fastened to rails by means of special fasteners and stretched. This system reliably protects the flooring from movement.

The couplers can be made in the form of tubular elements of circular cross section, on one end of which an external thread is made, and on the other end - an internal thread of the same size, and a flange with a base in the form of a hexagon is mounted. This allows you to conveniently connect the couplers to each other by screwing.

The surface of the flooring slabs for moving across the rail track contains protrusions, which in plan form a pattern containing alternating squares and blocks F consisting of four figures, which are a combination of an isosceles right triangle and an isosceles trapezoid, the larger base of which is the hypotenuse of the triangle. Inside block F, the figures are symmetrically arranged around a common nodal point J. The protrusions of the covering of the flooring plates can be made in the form of prisms and / or truncated pyramids. The coating may also contain around the perimeter protrusions in the plan having the shape of rectangles and triangles. Such an arrangement of the protrusions on the surface of the flooring plates, as shown by tests, provides the highest quality traction of vehicle wheels with them.

The flooring for crossing the rail track contains inner 1 and outer 2 plates laid respectively in the inter-rail and on both sides of the rail spaces, with obtaining at the level of the upper edge of the rails a surface for the movement of automobile transport, the plates being connected by longitudinal ties in the form of ties 3, inside of which fastening fittings 4 are placed, connected at the ends of the level crossing with rails. The joining of the inner plates 1 to each other and the outer plates 2 to each other is carried out by means of a tongue-and-groove connection of the end surfaces. On the end surfaces of both internal and external plates, on one side there is a spike 5 and on the other a groove 6. When connecting adjacent plates to a spike, before placing it in the groove, the channel is put on, and with it is inserted into the groove of the neighboring plate. Channel bars allow to give plates additional rigidity. The channels of the inner plates 7 are made with two holes for placement of the couplers of the system of fastening the plates between them, and the channels of the external plates 8 with one hole. The inner plate 1 is made with one mounting channel 9, two channels 10 for installing screeds and recesses 11 for placing intermediate rail fasteners in them, and the outer plate 2 is made with one channel 10 for installing screeds and recesses 11 for placing intermediate rail fasteners in them. The mounting channel 9 allows you to bend the inner plate during installation to establish it under the rail head. The lower surface of the interior flooring plates is molded in such a way that it repeats the surface of the sleepers at the place of laying on it. The top surface of the plate is a flat corrugated surface that provides the necessary coefficient of adhesion between the tires of the vehicle and the deck. The outer slabs 2 are based on one part of the sleeper and the other on the concrete corners 12, which in turn are supported on the distribution plates 13. The slabs can be made so that the width of the outer slab 2 is twice as wide as the width of the inner slab 1. Each a pair of inner plates 1 is attracted by two couplers 3, respectively, to already installed inner plates, and each outer plate 2 is attracted by one coupler 3, respectively, to already installed outer plates. After mounting all the couplers 3, a hole is formed that passes through the bodies of all the connectors, into which the fastening fittings 4 are placed, made, for example, in the form of a metal rod. On both sides of the crossing, the reinforcement by means of special fasteners 14 is attached to the rails and stretched. This system reliably protects the flooring from movement.

Ties 3 can be made in the form of tubular elements of circular cross section, on one end of which an external thread is made, and on the other end - an internal thread of the same size, and a flange with a base in the form of a hexagon is mounted. This allows you to conveniently connect the tie 3 together by screwing.

The surface of the flooring slabs for moving across the rail track contains protrusions which in plan form a pattern containing alternating squares 15 and blocks F consisting of four figures 16 representing a combination of an isosceles right triangle and an isosceles trapezoid, the larger base of which is the hypotenuse of the triangle. Inside the block F, the figures are symmetrically located around a common nodal point J. The protrusions of the surface of the flooring plates can be made in the form of prisms and / or truncated pyramids, the height of which can be 6 ÷ 10 millimeters. The surface of the flooring slabs may also contain around the perimeter protrusions in the plan having the shape of rectangles and triangles. As tests have shown, such an arrangement of the protrusions on the surface of the plates, as well as their shape, allows for increased adhesion of the vehicle wheels to the flooring even in adverse weather conditions.

Thus, the above-described construction of the deck for moving across the rail track can significantly increase its operational characteristics due to the improvement of the system of fastening plates between themselves and improving the quality of adhesion of the wheels of the vehicle to the surface of the leveling plates.
