Definitions
- the present invention relates to a liner for a sleeper railway track without ballast. Such channels are used especially in tunnels.
- the slipper gives to the track some elasticity in vertical directions and horizontal.
- the soles are made with an elastic material most often made of cellular rubber.
- this type of material can have a geometry that changes over time depending on storage conditions.
- This narrowing releases a peripheral volume which remains unoccupied between the crosspiece and the lateral edges of the sole to inside the envelope.
- the hydrostatic pressure of the concrete still liquid is sufficient to deform the wall of the envelope that comes then fill the existing void inside the envelope between its wall internal and sole.
- the object of the present invention is to solve these problems techniques satisfactorily.
- a shoe for railroad cross without ballast intended for be immobilized in a concrete bed comprising, on the one hand, a elastically deformable envelope receiving said crosspiece, the lower periphery is chamfered and comprising, on its internal wall, its lower part, recesses and, on the other hand, a sole resting under the cross member in the bottom of said envelope, characterized in that said recesses are made over a height corresponding to the thickness of the sole increased by the height of the chamfer of the crosspiece and in that the internal wall comprises, between the recesses, stiffening elements formed of extra thicknesses or bosses ensuring the reinforcement of said wall.
- the recesses are made both on the side wall and on the bottom extending under the edge of said sole.
- said stiffening elements are produced in the lower angle of the said envelope over a height corresponding to that of the sole.
- said recesses are formed of grooves.
- said recesses are formed of cells.
- the liner of the invention ensures operation correct static and dynamic track without ballast even in presence of a modified geometry of the sole.
- the sleeper In case of deformation of the envelope during the pouring of the bed concrete, the sleeper then continues to be resiliently supported without any "hard point" appearing.
- the recesses made on the inner wall of the envelope allow flexibility in all circumstances to be guaranteed compression when the cross member is pushed in.
- Figure 1 shows a cross-sectional view of a traditional slipper in the deformed state, with its cross.
- Figure 2 shows a cross-sectional view of a first embodiment of the boot of the invention in the free state, without crosspiece.
- Figure 3 shows a cross-sectional view of the Figure 2 liner deformed and immobilized in the concrete bed, with its cross.
- Figure 4 shows a cross-sectional view of a variant embodiment of the boot of the invention.
- the boot shown in Figure 1 is a boot traditional C for track T cross without ballast. This C shoe is immobilized in a concrete bed B.
- the bootie C comprises, on the one hand, an envelope 1 elastically deformable receiving the cross T and on the other hand a sole 2 resting under the crosspiece T in the bottom 12 of the envelope 1.
- the lower periphery of the cross-member T is provided with a chamfer t.
- the inner side wall of the casing 1 is provided with grooves peripherals 11 making it possible to provide both elasticity longitudinal and transverse to the cross T and a freedom of vertical travel of the crossmember when rolling loads pass over the way.
- the sole 2 may undergo shrinking due to poor storage conditions and no longer completely fill the housing intended for it at the bottom of the envelope 1.
- the free peripheral volume which then remains around the sole 2 is likely to be filled by the deformation of envelope 1 under the effect of the hydrostatic pressure of liquid concrete at the time of pouring bed B.
- This deformation creates a rigid zone forming a stop for the vertical travel of cross member T.
- the boot C of the invention shown in Figure 2 in the state free, without crosspiece, includes a casing 1, the lower part of which is provided on its internal wall with recesses 10.
- the recesses 10 are intended to guarantee to the envelope 1, a flexibility in compression even after deformation of the wall under the effect of the hydrostatic pressure of concrete.
- the recesses 10 are produced in the form of vertical grooves, the height is at least equal to the thickness of the sole 2 increased by the height of the bevel of the cross member T. In this way, the supports of the crosspiece T on the sole 2 and on the casing 1 are uniformly distributed and thus provide the cross member with an elastic support.
- the recesses are made in the form of cells.
- the grooves 10 possibly extend on the wall internal from the bottom 12 of the envelope 1 to below the peripheral edge of sole 2.
- the ends 10a of the grooves are bevelled to facilitate their release during the production of the C liner.
- Each groove corresponds to a weakening of the wall of envelope 1 and therefore a reduction in its intrinsic rigidity or an increase in its flexibility.
- the boot shown in Figure 4 corresponds to a variant embodiment in which the recesses 10, produced here in the form of splines, are separated by stiffening elements 13 formed of boss or extra thicknesses ensuring the reinforcement of the wall of envelope 1.
- the bosses 13 protrude in the lower corner inward of the envelope 1 and allow the angular zone of connection between the side wall and bottom 12 better resist deformation under external hydrostatic pressure.
- the height of the bosses 13 corresponds substantially to that of the sole 2 in the free state so that the underside of the cross-member T rests both on the sole and, by its peripheral edge, on the upper face of the boss 13.
- the sole 2 will be made initially with significantly shorter dimensions than for other modes of realization so that, in the free state and in the absence of deformation, there remains a slight clearance between the peripheral edge of the sole 2 and the vertical face of the boss 13.
