Abstract
The invention discloses a support rail plate, belonging to the construction element technique, which is mainly formed by concert and internal steel bar. Wherein, the middle part of longitudinal two ends of rail plate has a semi-circle cut; the support rail has symmetry supports which have symmetry distributed embedded insulated bolt sheathes; and the internal steel bar nodes of rail plate are insulated nodes. The invention has better insulated property, reduced cost, and easy production.
Description
Technical field
The present invention relates to a kind of railway construction member, be 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.
Summary of the invention
Based on above-mentioned need of practice, the objective of the invention is to: a kind of bearing platform type track slab that is applicable to ballastless track and has the good insulation performance is provided.
Technical scheme of the present invention is: a kind of bearing platform type track slab, mainly be to build by concrete and built-in reinforcing bar to form, 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.Track board concrete strength grade is C50.
Need to prove: the described direction that vertically is meant along track centerline, horizontal then be vertical with it direction.
Described track plate middle part short transverse has the hole, can save material like this, reduces the manufacturing cost of track plate.
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 arrangement of reinforcement is pressed track plate kernel of section line symmetric arrangement, 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.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 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 invention has the beneficial effects as follows: 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 installs more conveniently yet, and simultaneously the middle part of track plate has the hole, has saved raw material again, has reduced cost.
The present invention is further described below in conjunction with the drawings and specific embodiments.
