Abstract
The utility model discloses a rail joint method with stagger joint. The utility model belongs to the rail joint method with stagger joint. Two end surfaces of each segment of rails are changed into ladders, and the gaps are staggered after the segments of rails are joined, and therefore, larger vibration and the larger noise generated when the train runs are relieved. The rail joint method with stagger joint is favorable for the high-velocity running of the train.
Description
The utility model belongs to rail fissure of displacement connection method.
Two end faces of common each section of rail are concordant, because of iron has the physical property of expanding with heat and contract with cold, heave when preventing heat expansion during connection, stay a slit between section and the section, and this slit has produced very big vibration and noise during really to train vibration influence.
The purpose of this utility model is to provide a kind of rail fissure of displacement connection method, by changing two end surface shape of each lengths of rail, thus the bigger vibration and the noise that produce when having removed train vibration influence.
As shown in drawings, the utility model is to realize like this.All be processed into trapezoidal two end faces of each lengths of rail.Promptly the right side on rail head end 2 end faces of " I-shaped " shape half mill 15 millimeters deep, the first from left on terminal 3 end faces partly mills 15 millimeters deep.All be processed into the R5 millimeter between each face of stairstepping, with dispersive stress, the head end 2 of end 1 and back one lengths of rail of rail connects the last period, and stay the slit of 6 millimeter, the right and left is by clamping plate iron 4, with 6 identical bolts, be separately fixed at rail the last period do not hold 1 and the back one lengths of rail head end 2 on, on every lengths of rail by 3 bolt.
Stagger according to the rail segment of above-mentioned connection and the slit between the section, when train wheel is rolled into half gap at joint of the right side, the first from left half rail is supporting pressure, when train wheel is rolled into the first from left half gap at joint, right half rail is supporting pressure, and train travels on the rail that is not having the slit, operates steadily, reduced running resistance, the high speed that helps train travels.
Description of drawings:

1, the last period rail do not hold 2, back one lengths of rail head end
3, back one lengths of rail do not hold 4, clamping plate iron
5, bolt
Claims (1)
- A kind of rail fissure of displacement syndeton is processed into stairstepping at original rail two ends, it is characterized in that clamping plate iron 4 connects two rails by bolt, and dark 15 millimeters of the stairstepping that mills all is processed into the R5 millimeter between each face of stairstepping.
