RAILWAY CROSSING Russian patent published in 2019 - IPC E01C9/04 

FIELD: construction.

SUBSTANCE: invention is intended for the construction of railway crossings at the intersection of roads and railways. Railway crossing contains a reinforced concrete pavement laid on the inter-track interfacial space and on the side of the railway, consisting of inter-track, inter-railing plates and inter-railing baffle plates for all types of sleepers and rails, external elastic elements 6 and internal elastic elements 5. Double-side, inter-rail plates and inter-rail plates-bumpers from the side adjacent to the rail have a single-stage protrusion necessary for free placement of the rail-and-bolt fastener. Each of the inter-track, inter-railing plates on the sides, not adjacent to the rail, is edged with a metal corner, and the side of the plates adjacent to the rail, having a single-stage protrusion, is edged with metal channel 15, which completely covers single-stage protrusion 13. Each of the inter-rail slab plates on the sides of the plates adjacent to the rail is edged with metal channel 15, and the side adjacent to the inter-rail slab is edged with a metal corner. Upper surface of all these plates is made with corrugation and has at least two bushings, which are closed with plugs. Each sleeve with a plug has an internal thread for screwing the eyebolt. Intermediate slabs on the underside have at least two inserts 11 on one slab in the form of a metal angle, which securely connect the plates with the rail by means of clamp 17, consisting of holder 16 of clamp 17 with a hole and an anchor hook placed under the rail, anchored for mortgage part 11, inserted into the hole of holder 16 of clamp 17 and fixed with a nut. Outer side of inter-flight plate-bump 9, facing away from the crossing, is made in the form of a truncated prism, with a bevel at an angle of at least 45°, relative to the top surface of the slab and with a bevel relative to the track at an angle of not less than 60°.

EFFECT: increased reliability of the design, reduced complexity during installation.
