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 high speed, heavy haul train action of long-term load, 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, has seriously hindered railway and has developed to the direction of high speed, heavy duty.Therefore, non-maintaining or few maintenance, track ride comfort advantage good, good rigidity receive an acclaim ballastless track with it, but because Chinese track circuit transmission standard is by the track transmission signal of telecommunication, this track plate that just requires to be layed under the rail has the good insulation performance performance.
The utility model content
Based on above-mentioned need of practice, the purpose of this utility model is: a kind of longitudinal prestress track plate that is applicable to ballastless track, has good insulation performance, easy construction and economical with materials is provided.
The technical solution of the utility model is: a kind of longitudinal prestress track plate, comprise by concrete and built-in reinforcing bar and build the platy structure that forms, vertical both ends of the surface of track plate are symmetrically arranged with at least one breach, indentation, there is arranged with indented bars, one end of indented bars is built in plate, the other end of indented bars contains screw thread and exposes to indentation, there, the support rail position of track plate is symmetrically distributed with pre-buried insulation sleeve, the built-in reinforcing bar node of track plate is arranged with transverse prestressed reinforcing steel bar for the insulation node in the track plate.Described breach and screw thread are to be used for vertically connecting between the track plate.Above-mentioned pre-buried insulation sleeve is to be convenient to and the bolt insulation that rail is installed.Described transverse prestressed reinforcing steel bar is used to strengthen the cracking resistance of track plate.
Thickness direction is provided with spacing hole on the described track plate.When being used for the track plate and being installed on the roadbed, overcome the caused displacement under the wheel load effect of track plate.Described spacing hole is arranged on the longitudinal centre line of track plate.Described spacing hole is symmetricly set near on the longitudinal centre line at track plate two ends, makes the track plate stressed more even.
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 formed by vertical and horizontal reinforcing bar racking seizing, and longitudinal reinforcement adopts the insulating coating reinforcing bar, and for track plate plate body balancing performance, arrangement of reinforcement is pressed track plate kernel of section line symmetric arrangement.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.Certainly, for the insulation processing of the built-in reinforcing bar of track plate, can also adopt other insulation measures.
The coating of described insulating coating reinforcing bar is an 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.
Described transverse prestressed reinforcing steel bar is contained on the anchor plate, and anchor plate is positioned at track plate both lateral sides and builds in the track plate.
The beneficial effects of the utility model are: track intralamellar part reinforcing bar does not form the loop, does not produce electromagnetic induction; Vertical both ends of the surface of track plate are symmetrically arranged with at least one breach, and indentation, there is arranged with indented bars, have not only saved raw material, but also make things convenient for the vertical connection between the track plate; On track plate support rail position, be embedded with insulation sleeve, insulating properties that can more effective guarantee track plate; Be provided with the cracking resistance that transverse prestressed reinforcing steel bar can strengthen the track plate in the track plate; Thereby the track plate can not exert an influence to the rail signal transmission distance, and installs more convenient, quick yet.
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
