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.
In such scheme, the relative motion longitudinally of basic 1 upper surface can realize by the point supporting structure under described junction plate 3 and the line, described point supporting structure lays respectively between the junction plate 3 and the following basis 1 of line of 2 both sides, shrinkage joint, the line that the is positioned at shrinkage joint 2 one sides down point supporting structure on the basis 1 is movable point type supporting base 4, and opposite side is fixing point type supporting base 5.
Preferably, spacing is 10cm between the following basis 1 of described junction plate 3 and line.
In such scheme, the relative motion longitudinally of basic 1 upper surface can also realize by the planar slide braced structures under described junction plate 3 and the line, this planar slide braced structures is made of basic 1 upper surface under the junction plate 3 soffits line corresponding with it, and these two corresponding surfaces are planar slide and connect.
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.
The present invention 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 with line vertically relative motion of basis down, and limit 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 present invention installs simply, and is with low cost, can adapt to more complicated 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 feature of the present invention is done to describe in further detail, so that technician of the same trade understands.
