Problems solved by technology

[0003] In summary, the wooden sleepers and concrete sleepers in the prior art cannot meet the performance requirements of high-speed railways due to their own defects, especially the poor durability of wooden sleepers and the poor vibration and noise reduction of concrete sleepers, which not only make them High post-maintenance costs and high use costs, and poor environmental protection; polyurethane synthetic sleepers are also difficult to meet the technical and economic comprehensive requirements of high-speed railways for sleeper structures due to their structural integrity, stability defects and high use costs

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0023] See attached figure 1 to attach Figure 8 , the FRP frame type sleeper structure in the figure, comprises the sleeper beam member 1 for fixing rail 3; It is characterized in that:

[0024] The sleeper beam member 1 is made of FRP material, and the sleeper beam member 1 further includes an upper wing plate 11 and a lower wing plate 13, and the upper wing plate 11 and the lower wing plate 13 are connected through a middle web plate 12 to become hollow. I-shaped cross-section beam member, the hollow inner cavity of the I-shaped cross-section beam member is filled with polyurethane rigid foam I15, and the two ends of the sleeper beam member 1 support the rails, and two transverse partitions 14 are symmetrically arranged , the two transverse partitions 14 and their intersecting upper and lower wings 11 and 13 enclose a hollow rectangular cross-section mor...

Abstract

The invention relates to the technical field of a railway rail, in particular to an FRP framework type rail sleeper structure, which comprises rail sleeper cross beam components, wherein each rail sleeper cross beam component is made of FRP materials, and is a hollow I-shaped cross section beam type component consisting of an upper wing plate, a lower wing plate and a middle web plate, first polyurethane hard foam bodies are filled in hollow inner cavities of the I-shaped cross section beam type components, tongue-and-groove structures are arranged at the two ends of the rail sleeper cross beam components, the two adjacent rail sleeper cross beam components are connected into a whole through rail sleeper longitudinal beam components, each rail sleeper longitudinal beam component is also made of FRP materials, and is a hollow box-shaped cross section beam type component consisting of a top plate, a bottom plate and two side plates, second polyurethane hard foam bodies are filled in hollow inner cavities of the box-shaped cross section beam type components, and the two ends of the rail sleeper beam components are provided with tenons matched with the tongue-and-groove structures of the rail sleeper cross beam components. The rail sleeper structure is applicable to high-speed railways and has the advantages that the service life is long, and the use cost is low.

Description

technical field [0001] The invention relates to the technical field of railway tracks, in particular to an FRP frame sleeper structure suitable for high-speed railways with long service life and low use cost. Background technique [0002] With the development of high-speed railway construction, higher requirements for high-speed driving safety, comfort and environmental protection have prompted the sleeper structure supporting the rail to have a high initial structural flatness and high geometric invariance during service, as well as overall structural stability, It has good vibration and noise reduction, structural safety and durability, high degree of industrial construction, easy guarantee of project quality, low maintenance and cost-effective service life. Existing wooden sleepers and concrete sleepers are difficult to meet such high-tech requirements in terms of material performance, structural form, structural function and environmental protection effect. Polyuret...
