Abstract
A plate type structure of an under-crossing line structural joint of a railway ballastless track comprises an under-line base (1) of an expansion joint (2) and slabs (6) which are positioned on the under-line base (1), wherein the slabs (6) are unit blocking structures along the longitudinal direction. The plate type structure of the under-crossing line structural joint of the railway ballastless track is characterized in that: a connection plate (3) is arranged on the expansion joint (2) of the under-line base (1) and between the adjacent two slabs (6), and crosses the expansion joint, and the lower surface of the connection plate (3) is in plane sliding connection with the upper surface of the under-line base (1), which corresponds to the lower surface of the connection plate (3); and a limit structure which limits the lateral movement of the connection plate is also arranged in the structure. The plate type structure of the under-crossing line structural joint of the railway ballastless track is simple to install, has low cost, can be applicable to more complicated and wide railway under line bases, and is particularly applicable to the influences of under-line base deformation and displacement on the structure.
Description
Technical field
The present invention and non-fragment orbit structural joint relate in particular to structural joint plank frame under a kind of railway ballastless track crossover track.
Background technology
At present, unit sectional type non-fragment orbit adopts cast in situs road bed board or prefabrication track board-like usually, under this non-fragment orbit structure crossover track during structural joint, except that rail under lines such as Bridge Beam seam the structural joint place continuously, road bed board (or track plate), base etc. all disconnect at the structural joint place, and promptly the non-fragment orbit structure fails to realize structural joints such as leap Bridge Beam seam.When deformation took place on the basis under the line, the road bed board was shifted thereupon, causes the rail rapid wear.
At present railroad bridge span increase gradually, reason such as special bridge construction extensive use, cause the Bridge Beam seam to increase gradually, in this case, the non-fragment orbit structure is crossed over the Bridge Beam seam will be inevitable.Yet, also there is not railway unit sectional type non-fragment orbit at present, cross over the structure design of Bridge Beam seam.
The utility model content
Purpose of the present invention is in order to solve the deficiency that exists in the above-mentioned background technology, proposes a kind ofly can make structural joint under the unit sectional type non-fragment orbit crossover track, and adapts to structural joint plank frame under a kind of railway ballastless track crossover track of structural joint deformation under the line
For achieving the above object, the present invention adopts following technical scheme: structural joint structure under a kind of railway ballastless track crossover track, it comprises the following basis 1 of the line that contains shrinkage joint 2 and is positioned at the road bed board 6 on the basis 1 under the line, described road bed board 6 longitudinally is the unit fraction block structure, it is characterized in that, on the shrinkage joint 2 on online down basis 1, junction plate 3 is set between adjacent twice bed board Unit 6, this junction plate 3 is crossed over shrinkage joint, is the planar slide connection between basic 1 upper surface under the described junction plate 3 soffits line corresponding with it; In this structure, also be provided with the position limiting structure of constraint junction plate transverse movement.
In such scheme, described position limiting structure can be tongue and groove structure 7, and this tongue and groove structure is positioned at the corresponding two ends of junction plate 3 and adjacent road bed board 6, and this road bed board 6 is connected by the tongue and groove structure with junction plate 3.
In such scheme, described position limiting structure can also be made up of the limited block 6 that is positioned at junction plate 3 both sides, and the soffit of this limited block 6 is fixedlyed connected on basis 1 down with line.
Preferably, basic 1 upper surface is provided with one deck soft material layer 9 respectively near the place, shrinkage joint under the described line that is positioned at 2 both sides, shrinkage joint.
Furtherly, the length of described soft material layer 9 is less than the length of junction plate 3, and width is not less than the width of junction plate.
Furtherly, the thickness of described soft material layer is preferably 50mm.
The utility model designed a kind of can crossover track under structural joint be applicable to the structure of unit sectional type non-fragment orbit, this structure is provided with structural joint under the junction plate crossover track, junction plate can descend vertically relative motion of basis with line, and limits its transverse movement by the cross spacing transposition.When line when down the basis deformation, particularly longitudinal deformation takes place the shrinkage joint span is changed, junction plate can relative motion and do not produce deformation, has effectively protected non-fragment orbit.
The utility model is installed simple, and is with low cost, can adapt to complicated more and basis under the railway line widely, can adapt to distortion basic line under and the displacement influence to structure especially.
Below in conjunction with the accompanying drawing illustrated embodiment the utility model feature is done to describe in further detail, so that technician of the same trade understands.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, present embodiment comprises basis 1, road bed board 6, junction plate 3, shrinkage joint 2 and limited block 8 under the line.Described junction plate 3 and is located between adjacent two road bed boards 6 at this under adjacent lines on the shrinkage joint 2 of basis between 1, and the length of junction plate 3 is less than the spacing between above-mentioned adjacent two road bed boards 6.Described limited block 8 is positioned at the both lateral sides of junction plate 3, has retrained the transverse movement of junction plate, and the soffit of this limited block 8 is fixedlyed connected on basis 1 down with line.Being planar slide under the described junction plate 3 soffits line corresponding with it between basic 1 upper surface connects.
In the present embodiment, be positioned at that basic 1 upper surface is provided with the soft material layer 9 that a layer thickness is 50mm respectively near the place, shrinkage joint under the line of 2 both sides, shrinkage joint, as materials such as rubber, the length of soft material layer 9 is less than the length of junction plate 3, and width is not less than the width of junction plate 3.This soft material layer 9 can prevent from down vertical direction deformation to take place basis 1 when line, causes being unlikely to the jack-up junction plate when the basis upwarps under the line of shrinkage joint one end, is out of shape thereby influence rail.
Basic 1 upper surface under present embodiment junction plate 3 soffits and the line (part beyond the soft material layer 9) planar slide is connected, has realized junction plate 3 and has been positioned at basic upper surface relative longitudinal motion under the line of 2 both sides, shrinkage joint.
