Abstract

The invention relates to a steel rail beam anti-skidding surface layer which is applied to straddle type single-rail traffic. The steel rail beam anti-skidding surface layer is formed by reinforced concrete (1), and is located at the position of the traveling surface of a steel rail beam, and the reinforced concrete (1) of the anti-skidding surface layer is connected with a steel box beam (2) through shearing resistant connecting pieces (3). According to the steel rail beam anti-skidding surface layer, the traveling surface of the steel rail beam is covered with the reinforced concrete anti-skidding surface layer, the friction force between the traveling surface of the steel rail beam and train rubber tires can be increased, and the problem that the train tires are prone to slipping when it is rainy or the traveling surface is frozen in winter is effectively solved.

Description

Technical field [0001] The invention belongs to the field of straddle-type monorail transportation, and relates to an anti-skid surface layer of a steel track beam. Background technique [0002] At present, the steel track beams used in straddle monorail transportation have steel plates on the running surfaces of the track beams. When a monorail train passes the track beams, the friction coefficient between the rubber tires and the steel plate running surfaces is small. Especially in rainy days or in winter when the running surface is icy, the friction between the track beam surface and the rubber tires of the monorail becomes significantly smaller, and the monorail is prone to slip, often causing the monorail to stop. In order to increase the friction between the running surface of the steel track beam and the rubber tires of the monorail, it is often necessary to carry out special anti-skid treatment on the top surface of the steel track beam. Summary of the invention [0003] ...
