Description
Technical field
This utility model relates to a kind of railway bridge field, particularly to a kind of railway ballastless track attachment structure.
Background technology
Along with China Express Railway Line for Passenger Transportation and the fast development of urban track traffic, with few maintenance or do not keep in repair as spy
The non-fragment orbit of point has obtained fast development, and non-fragment orbit is the track replacing ballast bed layer with the material such as concrete, Colophonium
Structure, has few maintenance, a remarkable advantage that track stability is good, decreases track maintenance and repair work simultaneously, improves circuit
Utilization rate, decreases the consumption of this non-renewable resources of railway ballast, more environmental protection；In the long run, its economy is better than there is tiny fragments of stone, coal, etc. rail
Road；Our times various countries greatly develop high-speed railway, and application modern high technology builds high-speed railway, and non-fragment orbit becomes at a high speed
The important selection of railway track structure；Car body acceleration, car body load-carrying all will affect the using effect of non-fragment orbit and use the longevity
Life, existing non-fragment orbit attachment structure less consideration waterproof effect, stability, ride comfort and durability that track connects are relatively
Difference.
Utility model content
The purpose of this utility model is to provide that a kind of good stability, ride comfort be good and good endurance, can effectively improve
The non-fragment orbit attachment structure of Negotiation speed and safety.
To achieve these goals, the technical solution of the utility model is:
A kind of railway ballastless track attachment structure, including bridge, and is arranged on the track at bridge top, at the bottom of described track
Two-layer backing plate is fixed in portion respectively, arranges spring steel plate between two-layer backing plate, and screed-coat is fixed in the bottom of described spring steel plate, elastic
Arranging waterproof layer between steel plate and screed-coat, described screed-coat is positioned at the top of bridge, arranges side block block between bridge and track,
Described side block block one end connects the side of track, other end cross structure back portion, and described track includes base and track plates, described
The both sides, top of base are respectively provided with the most more than one convex gear platform, and convex gear platform is V-shaped, and track plates is positioned at both sides
Between convex gear platform, the two ends of track plates are respectively provided with the buckle matched with convex gear platform, and the both sides of track plates arrange track
Fastener.
Further, described backing plate is billet.
Further, the width of described screed-coat is more than the width of spring steel plate.
This utility model is a kind of railway ballastless track attachment structure, and it has the beneficial effect that
This utility model arranges two-layer backing plate between bridge and track, increases its bonding strength, arranges bullet between backing plate
Property steel plate, can bear and transmit vertical load, relax and suppress the impact caused by uneven road surface, track plates to be positioned at both sides
Between convex gear platform, the two ends of track plates are respectively provided with the buckle matched with convex gear platform, and convex gear platform plays location and reinforces
Effect, simultaneously facilitate the construction of track plates, this utility model can improve the train load vibration to subgrade bed effectively
Effect, good stability, ride comfort be good and good endurance, can effectively improve Negotiation speed and safety.

Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings:
As shown in FIG. 1 to 3, a kind of railway ballastless track attachment structure, including bridge 1, and it is arranged on bridge 1 top
Track, described rail base fixes two-layer backing plate 3 respectively, and described backing plate 3 is billet, arranges elasticity between two-layer backing plate 3
Steel plate 4, the bottom of described spring steel plate 4 fixes screed-coat 6, arranges waterproof layer 5 between spring steel plate 4 and screed-coat 6, described in look for
The width of flat bed 6 is more than the width of spring steel plate 4, and described screed-coat 6 is positioned at the top of bridge 1, arranges between bridge 1 and track
Side block block 7, described side block block 7 one end connects the side of track, other end cross structure back portion, and described track includes base 2 He
Track plates 10, the both sides, top of described base 2 are respectively provided with the most more than one convex gear platform 9, and convex gear platform 9 is V-shaped,
Between the track plates 10 convex gear platform 9 in both sides, the two ends of track plates 10 are respectively provided with the buckle matched with convex gear platform 9
11, the both sides of track plates 10 arrange rail clip 8.
The embodiment of the above, preferred embodiment the most of the present utility model, and unrestricted this utility model are real
Execute scope, therefore all equivalences done according to structure, feature and the principle described in this utility model the scope of the claims change or modify, all should
