Description
Technical field
The utility model belongs to track engineering field, more particularly, to a kind of lightweight rail traffic pre-fabricated one
Plate.
Background technique
Plate-type ballastless track is with speed of application is fast, appearance is neat and artistic, later period adjustment is convenient, maintenance workload is few
Outstanding advantages of, more and more urban track traffics in recent years start using plate-type ballastless track.Existing plate-type ballastless track
To ensure the uniformity of prefabricated board lower support and density, eliminate infrastructure construction error, the globality of railway roadbed and steady is improved
It is qualitative, it usually needs self-compacting concrete to be perfused under plate as leveling layer, existing main problem is：Lightweight city rail
Traffic usually requires that low cost, and self-compacting concrete cost is higher, should not use in lightweight rail traffic.
Utility model content
In order to solve the problems, such as background technique, the utility model provides a kind of lightweight rail traffic with prefabricated
Frame structure plate, the track engineering suitable for the lightweights rail traffic plate-type ballastless track such as railroad car, light rail.
The technical solution adopted in the utility model is：
The utility model includes two longitudinal support rail beams and two connecting cross beams, and two longitudinal support rail beams are flat along rail direction
Row is arranged, forms one by two connecting cross beams between two longitudinal support rail beams, two connecting cross beams are perpendicular to rail direction；
Arrange that track, track are set along rail direction arranged for interval, the lateral surface of two sides longitudinal direction support rail beam on every longitudinal support rail beam
Have it is horizontal for supporting, the accurate adjustment bolt hole of accurate adjustment and lifting.
Longitudinal support rail soffit below the track is pasted with point type rubber damping pad.
The lateral surface of two longitudinal support rail beams is equipped with along perpendicular to rail direction positive stop lug boss outstanding, and positive stop lug boss is located at
On straight line where connecting cross beam.
The lateral surface of every longitudinal support rail beam is equipped with two groups of spaced apart bolts hole, and every group of bolt hole includes two
Parallel and near to the accurate adjustment bolt hole of arrangement.
The longitudinal direction support rail beam is unidirectional prestressed structure, by longitudinal prestressing reinforcing bar, transverse structure reinforcing bar arranged crosswise
And casting concrete is made.
The connecting cross beam is made of reinforcing bar and concrete.
The utility model has the beneficial effects that：
When implementing at the scene, since board bottom size is smaller, common coagulation is can be used in the utility model pre-fabricated one plate
Soil replaces self-compacting concrete adjustment layer, track structure cost is greatly reduced, and maintenance is simple and convenient, lower to cost
Lightweight rail traffic has good adaptability.
The utility model not only has the advantages that plate-type ballastless track, but also can reduce lightweight rail traffic cost.
