Description
Technical field
The invention belongs to rail plate technique field, mainly solves the Insulation Problems of track plates and track circuit, is specifically one kind
Fragment-free track slab framework of steel reinforcement insulation system.
Background technology
There is track plates quality easily to ensure, durability is high, crack resistance is good, and speed of application is fast, and track recoverability is preferable etc.
Advantage, but because the reinforcing bar loop in track plates, base, convex blocking platform and rail are acted on by the mutual inductance between electric current, influence
The conveying length of resonant mode non-insulated track circuit；If not doing insulation processing, track circuit transmission distance requires poor with standard
Away from very big.
Therefore, it is necessary to which reducing transmission of the track plates section on track circuit influences, tested and tied according to the research of latest domestic
Fruit, the reinforcing steel bar insulating processing in track plates, which still has, need to handle the problem of number of steel bars is more, intractability is big；In usual engineering
The measure taken is the insulation between reinforcing bar；Insulation mode between reinforcing bar has two kinds, and one kind is that reinforcing bar crosspoint adds insulating sleeve
Or insulating blanked clamper, another kind are to use Epoxy Resin Coated Steel Bars.
But there is the problem of following in these insulation measures：
First, the crosspoint of reinforcing bar adds edge insulator or insulating sleeve；Edge insulator or insulating sleeve are typically moulded using common polythene
Material or nylon make, and polyethylene, nylon material and concrete shrinkage coefficient difference are larger under normal Warm, what its junction was easily formed
Hole, crack hair is easily produced, necessarily the durability of track plates is exerted an adverse impact, its influence degree is still not clear, and needs
To be examined by putting into practice.
Second, use coated reinforcement；The generation in crack source is avoided using coated reinforcement, but epoxy coating causes to mix
Coagulating the bond stress of soil reduces, and the bearing capacity and durability to structure produce large effect.
The Insulation Problems of track plates and track circuit, it is the weight that must be solved in China's non-fragment orbit large-scale promotion use
Want problem.
The content of the invention
The technical problems to be solved by the invention are：A kind of fragment-free track slab framework of steel reinforcement insulation system is provided, to solve
Bearing capacity and durability using the insulation technology such as traditional approach such as edge insulator or insulating sleeve, coated reinforcement to track harden structure
The problem of producing considerable influence.
The technical solution adopted in the present invention is：A kind of fragment-free track slab framework of steel reinforcement insulation system, including plate body are provided,
It is characterized in that：Prestress reinforcement structure and common reinforcement structure are provided with plate body, described prestress reinforcement structure is located at general
In logical reinforcement structure.
Further, described prestress reinforcement structure includes transversely prestressed bars and longitudinal prestressing muscle；Described transverse direction
Presstressed reinforcing steel is arranged in the middle part of plate body, and more of described transversely prestressed bars are arranged into one layer of transversely prestressed bars net, all horizontal strokes
Do not overlapped to presstressed reinforcing steel；Described longitudinal prestressing muscle is arranged on plate body upper and lower part, described longitudinal prestressing muscle
More are arranged into two layers of longitudinal prestressing muscle net, and the longitudinal prestressing muscle net described in two layers is arranged on plate body upper and lower part, institute
There is longitudinal prestressing muscle not overlap；Described transversely prestressed bars net and longitudinal prestressing muscle net is arranged apart, does not overlap mutually.
Further, described common reinforcement structure includes vertical structure reinforcing bar, auxiliary bar, bearing rod, flush type terminal, plating
Zinc band steel and transversary reinforcing bar；Described vertical structure reinforcing bar, auxiliary bar and transversary reinforcing bar composition hollow, rectangular reinforcing bar
Cage, described prestress reinforcement structure setting in hollow, rectangular steel reinforcement cage, described hollow, rectangular steel reinforcement cage upper and lower faces by
Vertical structure reinforcing bar arranges to form bar-mat reinforcement with transversary reinforcing bar, and described auxiliary bar forms around upper and lower two layers of bar-mat reinforcement
The wire side of hollow, rectangular steel reinforcement cage front, rear, left and right four, described bearing rod is arranged in hollow, rectangular steel reinforcement cage, and bearing rod
Do not touched with prestress reinforcement structure；The plate body both ends are stitched provided with malformation, and the bar-mat reinforcement both ends are close to movement joint
First row transversary reinforcing bar electrically welds with all vertical structure reinforcing bars intersected, transversary reinforcing bar in the middle part of the bar-mat reinforcement
With all vertical structure reinforcement weldings intersected；The drainage bar is two and plate body is below rail track, and position
In the vertical structure reinforcing bar with all transversary reinforcement weldings of overall rail roadbed surface layer；Other described longitudinal directions
Structure reinforcing bars, transversary reinforcing bar, bearing rod, auxiliary bar do not overlap mutually；The described bar-mat reinforcement composition main collection of stray electrical current
Monitoring net；Described zinc-coated flat steel sheet is welded on the vertical structure reinforcing bar of malformation seam both sides；The flush type terminal and plating
Zinc band steel welds.
Further, it is hot rolled ribbed bars that the vertical structure reinforcing bar and transversary reinforcing bar are some or all.
Further, plate body surface both ends are distributed with concrete track.
Further, the track plate body side surface is provided with the lifting sleeve pipe for lifting by crane.
Further, plate body surface is provided with service sleeve.
The pre-tensioned prestressed concrete track plates that the thickness that the present invention is exclusively used in plate is 260mm, this pre-tensioned prestressing coagulation
Native track plates are that the domestic intercity general location of track is to solve thin plate（100 ~ 200mm of thickness）Easily stick up in the process of running
A kind of pre-tensioned prestressed concrete track plates that song is deformed and used.
After above structure, following effect can be reached：(1) in the case of not increasing insulation measures, solves track
Influence problem of the vertical, horizontal reinforcing bar to track circuit in plate；(2) avoid to meet insulation measures that track circuit takes to rail
Guidance tape durability has an impact, and vertical, horizontal reinforcing bar crosspoint is more in the types of CRTS I, the type track plates of CRTS II, using sleeve pipe, absolutely
Edge card or coated reinforcement, the durability of bond stress and structure between concrete inherent quality, reinforcing bar and concrete can be produced
Raw adverse effect, and the reinforcement manner of pretensioned prestressing track plates of the present invention can thoroughly solve this problem；(3) economy
Good, the pre-tensioning system production lower-cost reason of pre-stress rail plate of the present invention is that the amount of reinforcement in track plates is less, saves
Using the expense required for coated reinforcement or insulating sleeve.
