Abstract
The utility model discloses a cushion cap type frame rail board, which belongs to a building member technology field. The utility model mainly comprises concrete and a plurality of built-in steel bars; a hole is arranged in the middle of the rail slab in height direction; the middle of the two longitudinal end faces of the rail slab is provided with a hemicycle gap; the rail supporting position of the rail slab is symmetrically distributed with a plurality of cushion caps; in the middle of the cushion caps are symmetrically distributed with a plurality of the preembedded insulated bolt thimble; the built-in steel bar nodes of the rail slab are insulated rails; the utility model is good in insulating property, furthermore, low in cost and more convenient to be manufactured and arranged.
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, occurred ballastless track is developed, 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 ballastless track and lower-cost bearing platform type frame rail plate of being applicable to is provided.
The technical solution of the utility model is: a kind of bearing platform type frame rail plate, mainly be to constitute by concrete and built-in reinforcing bar, track plate middle part short transverse has the hole, vertical both ends of the surface middle part of track plate is provided with semicircle breach, the support rail position of track plate is symmetrically distributed with cushion cap, be symmetrically distributed with pre-buried insulated bolt sleeve pipe in cushion cap, the built-in reinforcing bar node of track plate is the insulation node.
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.Above-mentioned cushion cap is to be formed on the support rail position of track plate by concreting, and rail is installed on the cushion cap, has so just increased the distance of rail and track intralamellar part reinforcing bar, helps the insulation between rail and the track plate more.Above-mentioned pre-buried insulated bolt sleeve pipe is to be convenient to and the bolt insulation that rail is installed.
Need to prove: the described direction that vertically is meant along track centerline, horizontal then be vertical with it direction.
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 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, does not produce electromagnetic induction; The corresponding position that rail is installed on the track plate is provided with cushion cap, has increased the distance of rail and track intralamellar part reinforcing bar, helps the insulation between rail and the track plate more; On cushion cap, be embedded with the insulated bolt sleeve pipe, insulating properties that can more effective guarantee track plate; Thereby the track plate can not exert an influence to the rail signal transmission distance, and makes, installs more convenient yet, and the middle part of track plate has the hole simultaneously, has saved raw material again, has reduced cost.
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
