Abstract
The utility model discloses a insulated frame track board which belongs to a structural element technolgy art. The board is a hollow frame type structure mainly comprised of concrete and reinforcing steel bar built-in. A semicircle gap is provided in the middle of longitudinal end face of the track board, of which both sides of the support track portion symmetricly distribute a pre-buried insulated bolt sleeve, inside the track board, the steel bar node is performed insulation treatment. The utility model has excellent insulation property in low cost to be suitable to use in area of warm environment.
Description
Technical field
The utility model relates to a kind of railway construction member, is specifically related to a kind of track plate.
Background technology
At present, China railways generally adopts ballasted track.Ballasted track has reached the limit of supporting capacity under long-term high speed, heavy haul train load act on repeatedly, show ballast bed destruction is constantly aggravated, the smooth-going degree variation of track, the maintenance activity amount strengthens, available maintenance time is fewer and feweri, and this has seriously hindered railway and has developed to the direction of high speed, heavy duty.Therefore, the development to ballastless track has appearred, but because Chinese track circuit transmission standard, promptly the signal of telecommunication is by track transmission, and this track plate that just requires to be layed under the rail has the good insulation performance function.
The utility model content
Based on above-mentioned need of practice, the purpose of this utility model is: a kind of ballastless track and lower-cost insulated type frame rail plate of being applicable to is provided.
The technical solution of the utility model is: a kind of insulated type frame rail plate, it is characterized in that: mainly be the hollow frame type structure that constitutes by concrete and built-in reinforcing bar, the longitudinal terminal surface middle part of track plate is provided with semicircle breach, the support rail position bilateral symmetry of track plate is distributed with pre-buried insulated bolt sleeve pipe, and the reinforcing bar node of track intralamellar part carries out insulation processing.
Above-mentioned semicircle breach matches with convex blocking platform on the base, overcome be subjected to support plate under the wheel load effect because of the caused counter-force of degree of disturbing.Pre-buried insulated bolt sleeve pipe is to be convenient to and the bolt insulation that rail is installed.
Track plate transverse side is provided with the lifting nut.Be convenient to the lifting and the carrying of track plate.
The reinforcing bar of track intralamellar part is by forming to the reinforcing bar racking seizing in length and breadth, and transverse reinforcement adopts plain bars, and longitudinal reinforcement adopts the insulating coating reinforcing bar.Cushioning insulation materials between the node of horizontal and vertical reinforcing bar, the effect of insulation materials are to prevent from that the coating of insulating reinforcing steel bars from breaking to form the loop, are the equal of the reliability of having strengthened the insulation of reinforcing bar node.Reinforcing bar binding adopts the colligation of insulated binding line.Make the reinforcing bar node of track intralamellar part insulate, the track plate does not form the loop to reinforcing bar in length and breadth, does not produce electromagnetic induction, thereby the track plate can not exert an influence thus to the rail signal transmission distance.
The coating of described insulating coating reinforcing bar is generally epoxide resin material.
Described insulated binding line is the insulating coating steel wire.The coating of described insulating coating steel wire is an epoxide resin material.
The beneficial effects of the utility model are: track intralamellar part reinforcing bar does not form the loop, do not produce electromagnetic induction, and the corresponding position of installing with rail is embedded with the insulated bolt sleeve pipe, can effectively guarantee the insulation function of track plate, and the middle part of track plate is the hollow frame structure, cost is lower, and the utility model is suitable for the warm area of environment to be used.
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Description of drawings
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the front view of Fig. 1;
Wherein, Reference numeral is: 1 is the insulated bolt sleeve pipe, and 2 are the lifting nut.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of insulated type frame rail plate, it mainly is the hollow frame type structure that constitutes by concrete and built-in reinforcing bar, the longitudinal terminal surface middle part of track plate is provided with semicircle breach, the support rail position bilateral symmetry of track plate is distributed with pre-buried insulated bolt sleeve pipe 1, the middle part of track plate is the hollow frame structure, the reinforcing bar node of track intralamellar part carries out insulation processing, track plate transverse side is provided with lifting nut 2, the reinforcing bar of track intralamellar part is by forming to the reinforcing bar racking seizing in length and breadth, transverse reinforcement adopts plain bars, longitudinal reinforcement adopts the epoxy resins insulation coated reinforcement, cushioning one deck insulation materials between the node of horizontal and vertical reinforcing bar, reinforcing bar binding adopt the colligation of insulated binding line, and its insulated binding line is an epoxy resins insulation coating steel wire.
