The track slab (10) adopts a prestressed reinforcement concrete structure, the slab body of the track slab adopts a flat plate, the orthographic projection of a slab surface is in the shape of a rectangle, and a connecting element extending out of the bottom surface of the slab body is fixedly arranged in the track slab in an embedding manner.
Description
Technical field
The utility model relates to railway ballastless track, particularly a kind of non-fragment orbit track plate.
Background technology
At present, widely used ripe non-fragment orbit pattern has double-block type and CRTSI, CRTSII template formula non-fragment orbit.Wherein, CRTSI template formula track elasticity is good, easy to maintenance, and its great advantage is that the track plate is prefabrication production, can reduce the site work amount to greatest extent, improves mechanized operation level, accelerating construction progress.The track plate of CRTSI template formula non-fragment orbit has two kinds of patterns, frame plate and flat boards.Dull and stereotyped anti-seismic performance is better than frame plate.Can save material though frame plate is compared flat board, reduce construction investment, the ponding easily at the frame plate middle part will produce a large amount of ponding in the plate during impeded drainage under the plate, influence the durability of mortar bed and track structure.
In existing ballastless track structure, generally adopt cement-asphalt mortar, bituminous mortar (CA mortar) as adjusting layer.But the advantage of CA mortar adjustment layer is a convenient for maintaining to be changed, but because CA mortar adjustment layer can not be connected to integral body with track plate, understructure layer, for retraining the influence of horizontal train load and vertical equity brake force to track, circular convex blocking platform need be set on base at interval, vertical two ends at every block of track plate are provided with corresponding breach, therefore the track plated construction is comparatively complicated, and the deficiencies such as passage has some setbacks of constructing, the speed of application that is unfavorable for reducing construction cost and accelerates track.
The utility model content
Technical problem to be solved in the utility model provides a kind of non-fragment orbit track plate, this track plate can with adjust layer, bearing bed forms the overall composite track structure, and structure further simplifies, prefabrication production and site operation are more convenient.
The technical scheme that its technical problem that solves the utility model adopts is: non-fragment orbit of the present utility model track plate, and the track plate adopts prestressed reinforced concrete structure, it is characterized in that: the plate body of described track plate is for dull and stereotyped, and the orthography of its plate face is rectangular; Described track plate is buried underground and is set with the connecting elements that extends its plate body bottom surface.
The door shaped steel muscle that described connecting elements is buried underground for be partitioned into row along rail plate long degree direction, fixedly connected with arrangement of reinforcement in the track plate in the top of each shaped steel muscle.
The beneficial effects of the utility model are, form the overall composite track structure with adjustment layer, bearing bed, can improve the globality of track, satisfy the requirement of non-fragment orbit, and can solve the track plate effectively and the asphalt mortar, bituminous mortar packed layer is easily peeled off, track plate longitudinal end easily produces problems such as warpage stationarity, comfortableness; The track plated construction is further simplified, neat appearance, and prefabrication is produced more convenient; Owing to can save on the base and at interval circular convex blocking platform is set, so site operation is more convenient, help improving construction speed and reduce construction costs.

Fig. 3 is the vertical view of the utility model non-fragment orbit with the track plate;
Fig. 4 is the utility model non-fragment orbit with track plate and the longitudinal section schematic diagram of adjusting layer, overall composite track structure that bearing bed constituted.
Component shown in the figure, toponym and pairing mark: track plate 10, door shaped steel muscle 11, shoulder block 12, adjustment layer 20, bearing bed 30, position limiting structure 31.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, non-fragment orbit of the present utility model adopts prestressed reinforced concrete structure with the track plate, and the plate body of track plate 10 is dull and stereotyped, and the orthography of its plate face is rectangular, and structure is further simplified, neat appearance, and prefabrication is produced more convenient; Owing to can save on the base and at interval circular convex blocking platform is set, so site operation is more convenient, help improving construction speed and reduce construction costs.Described track plate 10 is buried underground and is set with the connecting elements that extends its plate body bottom surface, with reference to Fig. 4, can make track plate 10 and adjust layer 20, bearing bed 30 formation overall composite track structures by connecting elements, can improve the globality of track, satisfy the requirement of non-fragment orbit, and can solve the track plate effectively and the asphalt mortar, bituminous mortar packed layer is easily peeled off, track plate longitudinal end easily produces problems such as warpage stationarity, comfortableness.
Described connecting elements can adopt multiple structure, as the pre-buried WELDING STUDS in the track plate 10, the reinforcement component of different shape etc. of being fixed on, shown in Fig. 2 is wherein a kind of preferred structure, it is the door shaped steel muscle 11 that described connecting elements is buried underground for be partitioned into row along track plate 10 length directions, fixedly connected with arrangement of reinforcement in the track plate 10 in the top of each shaped steel muscle 11, its plate body bottom surface is extended in the bottom.With reference to Fig. 2, described door shaped steel muscle 21 can be laid two row usually, is laid in the below of location of rail at interval along track plate 20 widths.
With reference to Fig. 2, describedly be used to retrain the traversing shoulder block of rail fastening 12 along being laid with two row on the surface of track plate 10.The curve location adapts to the rail of superelevation variation and sharp radius curve to the adjustment problem by elevation and the plan-position of adjusting rail support groove, therefore it is linear to be fit to little curve, can further reduce fastener rigidity, and possess application property and gauge hold facility preferably.
Shown in Fig. 4 is track plate 10 of the present utility model and the overall composite track structure of adjusting layer 20, bearing bed 30 formation.Adjust layer 20 a self-compacting concrete layer that adopts, protruding the extending into of the following subordinate of door shaped steel muscle 11 is adjusted in the layer 20, and track plate 10, adjustment layer 20 are connected as one.30 of bearing beds have the position limiting structure 31 that acts on adjustment layer 20, to retrain the influence to track structure of horizontal train load and vertical equity brake force, structure are played the effect of further reinforcement.Position limiting structure 31 can adopt positive stop lug boss or the limited impression of laying at interval along bearing bed 30 center lines.
The above the utility model non-fragment orbit some principle that just explain through diagrams with the track plate, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
