Abstract
The invention discloses a curve type track slab with shoulder, belonging to the track slab technical field. The track slab comprises a track slab body, the end part of the track slab body is provided with a groove, the two rows of track-bearing table boards with shoulders are provided with track bottom slope of 1:38-42; the central line of two rows of embedded sleeves arranged on each track-bearing table with shoulder is in curve distribution along the horizontal direction of the track slab body, the horizontal projections of the curve and the central curve of steel rail are concentric circle curves. The invention can deviate the track-bearing table with shoulder along the width and height directions of the track slab according to design requirement, so as to meet the requirement of physical space line shape of track.
Description
Technical field
The present invention relates to a kind of track plate, especially relate to a kind of track plate of inter-city high-speed rail upper curve section track laying.
Background technology
Rail support groove and bed die on the desk-top railway plate die of existing support rail are integral structures; This structure is feasible for linear pattern track plate, but just no longer suitable for the circular curve type of inter-city high-speed rail upper curve section and easement curve type track plate.The circuit straightway of high-speed railway and the changeover portion between the circular curve segment are called the easement curve section, and the track plate of laying on this easement curve section is called easement curve type track plate; Having crossed the easement curve section is exactly the standard circular segment, and the track plate of laying on this standard circular segment is called circular curve type track plate.Because the curve radian of circuit is different, needed curve type track slab is also different, and especially the easement curve section requires to heighten outside support rail platform and satisfies superelevation and change the outer rail that causes and raise.
Summary of the invention
The objective of the invention is to: providing a kind of can have a shoulder block curve type track slab with what adapt to the linear needs of track real space with there being shoulder block support rail platform by designing requirement skew to take place along track plate width and short transverse.
Technical scheme of the present invention is: a kind of have a shoulder block curve type track slab, comprises track plate plate body, and two rows of said track plate have shoulder block support rail platform table top to be provided with 1: 38～1: 42 rail cant; Said every row has center line curved layout on track plate plate body horizontal direction of two row's service sleeves that shoulder block support rail platform is provided with, and this curve and rail center curve horizontal projection are the concentric circles curve.That is to say that every row has shoulder block support rail platform on track plate plate body, according to the orbital curve line style certain transversal displacement to be arranged.
Said every row has shoulder block support rail platform curved layout on track plate plate body thickness direction, and this curve and rail center curve vertical projection are the concentric circles curve.That is to say that every row has shoulder block support rail platform according to the orbital curve line style certain amount of heightening to be arranged in the short transverse of track plate plate body.
The corresponding bottom surface of said track plate plate body support rail platform longitudinal direction is embedded with at least two row's rectangle reinforcing bars, and rectangle reinforcing bar lower end is exposed to outside the track plate plate body.Make the track plate more reliable with being connected of roadbed.
Said track plate plate body bottom surface longitudinal direction respectively is embedded with row's rectangle reinforcing bar near the plate body marginal position.
The invention has the beneficial effects as follows: can be there being shoulder block support rail platform skew to take place to adapt to the linear needs of track real space by designing requirement along track plate width and short transverse.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further specified.
