Abstract

A railroad sleeper comprises a sleeper body (1) and railway bearing areas (3). Each railway bearing area (3) is provided with a railway bearing face (5), first reinforcing components (6) and second reinforcing components (7). The sleeper body (1), the first reinforcing components (6) and the second reinforcing components (7) are all made of composite materials, and the surface of the sleeper body (1) is sequentially provided with a flame retardant layer, a wear-resisting layer and a flame retardant layer. The composite materials comprise polyurethane resin formed in a foaming mode and a plurality of glass fibers arranged in the polyurethane resin. The flame retardant layers are formed by polyurethane resin coatings added with inorganic filler materials, and the polyurethane resin coatings are the same as the polyurethane resin of the sleeper body (1) in texture. The railroad sleeper is low in density, long in service life, good in damping effect, capable of bearing high load, stable in performance, high in weather fastness, easy to machine and install.

Description

technical field

[0001] The invention relates to the field of railway tracks, and more particularly relates to a railway sleeper. Background technique

[0002] Railway is currently one of the most important means of transportation in the world. With the development of railways towards high speed, heavy load and environmental protection, the requirements for tracks are getting higher and higher. As an important part of the track, the sleeper is used as a cushion under the rails, and maintains the gauge, level, height and direction between two or more strands of rails through the mutual connection parts, and prevents the rails from being caused by trains. The longitudinal crawling generated by driving and the equal distribution of various loads on the rails on the foundation of the ballast bed, its materials and structures are constantly being developed and updated.

[0003] Currently used sleepers mainly include wooden sleepers, steel sleepers and concrete sleepers. As a sle...

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] A railway sleeper comprising a sleeper body 1 with two blocks 2 each having a track bearing area 3 in which the sleeper body 1 is widened . The rails are secured in each rail bearing region 3 by means of pressure elements 4 engaging the rail base. Each rail bearing area 3 has three rail bearing surfaces 5 arranged side by side in the direction of rail extension, with gaps 8 provided between the rail bearing surfaces 5 . At least one pressing element 4 is arranged on each said rail bearing surface 5 or in the gap 8 in each rail bearing region 3 . At least one first stiffening element 6 arranged in the direction of extension of the track extends respectively within the sleeper body 1 below the track bearing area 3; at least one second stiffening element 7 passes through the sleeper body 1, The second stiffening elements 7 extend in the ...
