Rail mounting device and method for fîxing rails to reinforced concrète railway sleeper

The object of the invention relates to a rail mounting device for fîxing railway rails to •ecially for fîxing without a baseplate, which device has a nonsecond state, and which device contains an anchoring element reinforced concrète sleepers, esp fîxing first state and a rail fîxing fixed to the reinforced concrète sleeper providedwith an open or closed bracket piece, and a railclamping plate partially or entirel

The object of the inven:

concrète sleepers.

The task of the rail mounting device is to provide a firm yet flexible connection between the railway rail and the sleeper supporting it. Numerous rail mounting devices hâve been used in the course of the history of the railways, which may be classed into three big groups according to the method of clamping.

The first group includes y encompassed by the bracket piece of the anchoring element. don also relates to a method for fîxing rails laid on reinforced the earliest solutions using direct rail spikes or rail bolts, which fixed the rail directly to the sleeper. Even today this solution is occasionally used due to its simplicity and cost-effectiveness, however, its significant disadvantage is that it is not suitable for fîxing rails subjected to greater loads and the fîxing of the rails soon becomes loose.

des the baseplate rail fîxing solutions, in the case of which the

The second group inclut baseplate is fixed directly to the sleeper, and the rail is fixed to the baseplate using fixing devices, such as rail bolts.The appropriate magnitude may be e: used on railway lines subject to greater loads. However, the great disadvantage of baseplate fixing is that it provides a connection that is overly rigid, which may lead to increase fatigue of the connections and their breaké.ge. A further disadvantage is that the regular inspection of the fixtures and the tightening of the

The flexible connectic disadvantages of the solutions p resented above, with which it is possible to fix rails without the fixtures becoming loose.Rail fastening realizing flexible fixing is disclosed, for example, by patent application number WO )202873, which is used in the case of a well known type of railway baseplate, the K-plate lype. The patent spécification discloses a railway rail clip that does not hâve to be compresse elongated member that is bent so that the member’s lower part forms a lower limb portion and the member’s upper part forms advantage of the solution is that a clamping force of the stablished with the rail bolts, therefore this technology may be rail bolts are time-consuming and costly.

ns belonging to the third group successfully overcome the d when fitted. The task is solved by that the rail clip has an an upper limb portion. The lower limb portion forms the base

-2portion of the rail clip, which engages the slot in the baseplate, the upper limb portion extends further than the lower limb portion, and its free end forms a toe portion of the rail clip, which rests on the rail foot. Similar rail clip structures are disclosed by patent documents US 3,067,947 and US 4,313,563. The main disadvantage of these solutions is that as a resuit of their spécial shape the manufacture of the rail clip is expensive, and they require a baseplate, which increases costs even further.

It was recognised that the flexible fixing of rails to sleepers can be provided in a simpler way and at a lower cost than the solutions according to the state of the art using a rail mounting device containing a rail-clamping plate established as an unbent flat plate, and an anchoring element encompassing it positioned at an angle to the upper plane of the sleeper, where the angle between the rail-clamping plate and the upper plane of the sleeper is at least 5 degrees, preferably 5 to20 degrees, even more preferably 10 to 15 degrees.

It was also recognised that establishing the rail-clamping plate at the above angle to the s it possible to create sufficient rail-clamping force using less upper plane of the sleeper make material than in the rail fixing solutions according to the state of the art.

It was also recognised 1hat if the angle between the rail-clamping plate and the upper plane of the sleeper is at least 5 degrees, then it is sufficient to use a rail-clamping plate which has a maximum thickness of 6 m im. The récognition also includes that the rail-clamping plate not exceeding 6 mm in thickness miy be produced from sheet steel using a sheet cutting process. Sheet steel is significantly cheaper than cast steel, and sheet cutting losses and costs are lower than those of casting and other c ommonly used processes, due to this the production of the raile invention is faster and simpler compared to the solutions clamping plate according to th according to the state of the art, and its production costs are significantly lower.

The objective of the invention is to provide a rail mounting device and method that is free of the disadvantages of the solutions according to the state of the art.

In accordance with the invention, the task was solved with the rail mounting device according to claim 1 and with the method according to claim 12.

Figures la and 1b are schematic top views of a preferred embodiment of the rail mounting device 10 according to the invention. For the purpose of clarity those parts that would otherwise be covered in top views are shown in figures la and lb with dotted fines.

The rail mounting device 10 serves for directly or indirectly fixing railway rails 12 to reinforced concrète sleepers. In the présent spécification indirect fixing is understood to mean that a spacer, such as an electrically insulating plate, is positioned between the rail 12 and the reinforced concrète sleeper 14, in this way the rail 12 and the reinforced concrète sleeper 14 do not corne into direct contact with each other. Direct fixing is understood to mean the case when there is direct contact between the rail 12 and the reinforced concrète sleeper 14. The device 10 has a first state when it is not fixing the rail 12 and a second state when it is fixing the rail 12, which first and second state are f resented in figures 2a and 2b respectively.

In the context of the présent invention reinforced concrète sleeper 14 is understood to mean the sleepers commonly us ed for railway tracks, such as pre-stressed reinforced concrète sleepers, as is known by a persor. skilled in the art.

The device 10 contains an anchoring element 18 fixed to the reinforced concrète sleeper 14 providedwith an open or closed bracket piecelô, and a rail-clamping plate 20 partially or entirely encompassed by the bracket piece 16 of the anchoring element.The anchoring element 18has an upper surface which is formed substantially fiat and which is at an angle to an upper

-4plane 22 of the reinforced concrète sleeper 14 such that the distance between the first edge of the upper surface of the anchoring element 18 doser to the rail 12 and the upper plane 22 of the reinforced concrète sleeper 14 is smaller than the distance between the second edge of the upper surface of the anchoring element 18 more distant from the rail 12 and the upper plane 22 of the reinforced concrète sleeper 14.

The anchoring element 18 is fixed to the reinforced concrète sleeper 14 in a releasable or non-releasable manner. A rele isable connection may be provided, for example, using the boit 15 shown in figures 2a and 2b. T be fixed subsequently to the aire optionally the anchoring element ways, by using clips, threaded releasable fixing may be provided, for example, with casting, or with the use of spécial adhesives, such as concrète adhesive. The embodiments shown in figures 3a, 3b, 4a, and 4b only differ from that presented above concreted into the reinforced com the production of the reinforced concrète sleeper 14, or preferably during the manufacture of the reinforced concrète sleeper 14 simultaneously with the casting of the reinforced concrète sleeper 14. In the case that the anchoring has a shape that curves under the rail 12, as can be seen in figures 4a and 4b. The fixing can be strengthened further with this arrangement Naturally, optionally the use of a differently shaped (e.g. straight, plate-shaped, etc.) skilled in the art.

The bracket piece 16 o|the anchoring element 18 partially or completely encompasses the rail-clamping plate 20, as can be seen in figures la and 1b. In the case of a particularly preferred embodiment the anchoring element 18 is established as a structurally single element, preferably as a métal casting. With respect to its material the anchoring element 18 may be made from iron, steel, or other métal which the anchoring element 18 example, the bracket piece 16 separately. The various parts may be fixed to one another by a releasable (e.g. with bolts) or a non-releasable connection (e.g. by welding).

The shape ofthe rail-cl imping plate 20 may be rectangular, as can be seen in figures la and lb, or other planar piece mounting device 10 is establish ’he advantage of this is that the anchoring element 18 may even :ady laid reinforced concrète sleeper 14. It should be noted that t 18 may be fixed to the reinforced concrète sleeper 14 in other rods, etc., as is known by a person skilled in the art. Nonin that the anchoring element 18 has a lower fixing piece 17 crete sleeper 14. The concreting may optionally take place after element 18 is in fixed state the lower fixing piece 17 preferably lower fixing piece 17 is conceivable, as is obvious for a person alloy. Optionally an embodiment is conceivable in the case of is established from several parts fitted together, in this way, for and the lower fixing piece 17 may even be manufactured that, for example, narrows towards the second end.The rail ed in its first state illustrated in figures 2a and 4a with the rail19138

-5the first end of the rail-clamping plate 20 doser to the rail 12 clamping plate 20 at an angle to ihe upper plane 22 of the reinforced concrète sleeper 14 in such a way that the distance between and the upper plane 22 of the reinforced concrète sleeper 14 is smaller than the distance between the second end of the rail-clamping plate 20 more distant from the rail 12 and the upper plane 22 of the reinforced concrète sleeper

14.

In the context of the présent invention the distance between the first end of the railplane 22 is understood to mean the length of the section from 22 that is perpendicular to the upper plane 22. Similarly, the f the section from the second end to the upper plane 22 that is clamping plate 20 and the upper the first end to the upper plane distance between the second end of the rail-clamping plate 20 and the upper plane 22 is understood to mean the length o perpendicular to the upper plane 22.1n the présent spécification the upper plane 22 of the reinforced concrète sleeper 14 is viewed as being the plane of the surface of the reinforced concrète sleeper 14 under the rail 12 directly supporting the rail 12. For the sake of clarity, the upper plane 22 has been marked

The rail-clamping plate established as an unbent flexible particularlypreferred embodiment the angle between the rail-clamping plate 20 and the upper plane 22 of the reinforced concrète sleeper is at least 5 degrees, preferably 5 to 20 degrees, even more preferably 10 to 15 degrees. In this case it is sufficient to select the thickness of the railclamping plate 20 to be 6 mm exceeding 6 mm in thickness me y be produced from sheet steel using a sheet cutting process, in other words the rail-clamping p! mm. Sheet steel is significantly lower than those of casting and e ther commonly used forming processes.As a conséquence of the above, the production costs of the rail-clamping plate 20 are significantly lower than those ofthe solutions according to the state rail-clamping plates 20 require advantage.

With the rail mounting by a dotted line in figures 2a and 2b.

of the rail mounting device 10 according to the invention is fiat plate, in other words as a planar leaf-spring. In the case of a

The advantage of this is that the rail-clamping plate 20 not ate 20 may be produced from eut sheet steel no thicker than 6 cheaper than cast steel, and sheet cutting losses and costs are of the art, which, taking into considération the large number of :d for railway construction, represents a significant économie device 10 in its second state, in other words when fixing the rail 12 to the reinforced concrète sleeper 14, the rail-clamping plate 20 is fixed to the anchoring element 18, preferably in a releasable way, so that its first end is laid onto the base 12a ofthe rail 12, and the shape ofthe rail-clariping plate 20 is a convex curve viewed from the direction ofthe upper plane 22 ofthe reinforced concrète sleeper 14, as can be seen in figure 2b and 4b.In the case of a preferred embodiment the first end of the rail-clamping plate 20 is provided with an

-6electrically insulating covering 24, which prevents electric contact between the rail 12 and the rail-clamping plate 20. The insul ating covering 24 is fixed to the first end with a rétention lock, for example, but naturally the use of other fixing methods is also conceivable, such as the use of an adhesive, for example.

In the case of the embodiment shown in figures 4a and 4b the reinforced concrète and a second surface 60 protruding out of the plane of the first sleeper 14 has a first surface 50 surface 50, and the anchoring élément 18 rests on the first and second surfaces 50, 60. The first surface 50 is preferably planar in shape and coïncides with the upper plane 22. The second surface 60 is also planar, and in the way illustrated in figures 4a and 4b it is at an angle to the first plane 50. Naturally, an emtodiment is optionally conceivable in the case of which the first and second surfaces 50, 60 are not planar, instead they are curved, arched, undulating, broken, etc. surfaces.In the case of a particularlypreferred embodiment, the vertical thickness of the part of the anchoring element 18 rest ng on the second surface 60, in other words the thickness of the part of the anchoring element 13 between the surface 60 and the rail-clamping plate 20 is less than the vertical thickness of the part resting on the first surface 50, in other words the part of the anchoring element 18 between the surface 50 and the rail-clamping plate 2O.The shape of the top view of the anchoring element 18 may be, for example, rectangular, or, as indicated with a broken line in figures 3a and 3b, a planar piece that narrows towards its end.

The rail mounting device 10 according to the invention also preferably contains an electrically insulating spacer element 28 arranged on the rail 12 side of the anchoring element 18 fixed to the reinforced concre:e sleeper 14, the purpose of which is to prevent electrical conductance between the rail 12 and the rail mounting device 10. The spacer element 28 is preferably made from plastic, but, optionally the use of other non-electrically conducting materials is conceivable, such is composites, as is known by a person skilled in the art.An electrically insulating sheet 26 is preferably arranged between the rail 12 and the reinforced concrète sleeper 14.

With the rail mounting device 10 in its second state the rail-clamping plate 20 is fixed to the anchoring element 18. The fixing may take place in a way that provides a releasable or nonreleasable connection. In the cas anchoring element 18 more dist movement of the rail-clamping second state, which flange 29 is

18.The flange 29 supports the rail-clamping plate 20 from the rear thereby preventing it from slipping off the rail 12.

; i of the embodiment shown in figures 2a and 2b the end of the :mt from the rail 12 is provided with a flange 29 preventing the plate 20 in the case that the rail mounting device 10 is in its preferably formed out of the material of the anchoring element

-7In the case of the exemplary embodiment shown in figures 4a and 4b the second end of ie anchoring element 18 are provided with a dépréssion 30a and the rail-clamping plate 20 and th a protrusion 30b fitting into tte dépréssion 30a, which together form a rétention look for preventing the rail mounting device 10 from getting from the second state to the fïrst state. The protrusion 30b is formed in the rail-clamping plate 20. Optionall arrangement is the other way aro

20, and the dépréssion 30a in the anchoring element 18 and the dépréssion 30a is formed in the y, an embodiment is also conceivable in the case of which the >und, the protrusion 30b is to be found in the rail-clamping plate anchoring element 18.

The object of the invention also relates to a method for fixing rails 12 to reinforced ich the rail mounting device 10 in its fïrst state presented above by the bracket piece 16 faces the railway rail 12. In the case of a ice this takes place so that at the site of the construction of a on the track bed of the railway line, then the railway rail 12 is vice 10 in the position shown in figures 4a and 4b.Naturally, if :he reinforced concrète sleeper 14 has been laid (e.g. in the case concrète sleepers 14, during whi in the vicinity of the railway re il 12 is provided in such a way that the fïrst end of the railclamping plate 20 encompassed preferred embodiment, in practi railway line a reinforced concrète sleeper 14 provided with the rail mounting de vice 10 according to the inventionis laid laid next to the rail mounting de the anchoring element 18 is fixed to the reinforced concrète sleeper 14 with a boit 15, then the fixing may also take place after of renovating a railway line).

In the case of a particul irlypreferred embodiment a rail mounting device 10 is provided on each of the two sides of the railway rail 12, essentially opposite one another, with which the rail 12 is fixed to the reinforced concrète sleeper 14 from two sides. With this solution movement ofthe rail 12 in directions perpendicular to the railway line can be prevented.

In the second step of the method according to the invention the rail-clamping plate 20 is pushed towards the rail 12, in other words the rail mounting device 10 is taken from the fïrst state shown in figure 2a to the second state shown in figure 2b. In the case of a preferred embodiment, the rail-clamping p late 20 is pushed towards the rail 12 by hitting the second end of the rail-clamping plate 20 one oi the tool 40 illustrated in figure i a.The tool 40 may be established using a traditional hammer by replacing the wooden handle of the hammer into the shape shown in figure 5a. The great advantage of the rail mounting device 10 according to the invention is that getting it from the fïrst state to the second state does not necessarily require the use of a 5 pecial dedicated tool.

The rail-clamping plate 20 is at an angle to the upper plane 22 according to that r more times using a traditional hammer, or, for example, using the hammer with a métal handle, and by machining the head of

-8described above. By pushing the rail-clamping plate 20 towards the rail 12, the fîrst end is forced up against the base 12a of the rail 12, and the fîrst end rises vertically, while the bracket piece 16 does not permit the rail-clamping plate 20 to move upwards. As a resuit, the rail-clamping plate 20 bends in such a way that it takes on a convex curved shape viewed from the upper plane 22 of the reinforced concrète sleeper 14. As a resuit of the bending spring force is created in the rail clamping plate 20, which forces the rail 12 onto the reinforced concrète sleeper 14.As the rail clamping plate 20 is establishec at an angle to the upper plane 22 of the reinforced concrète sleeper 14 as described above, by pushing the rail-clamping plate 20 towards the rail 12 the vertical increase in height of the fîrst end is greater than if the rail-clamping plate 20 were parallel or at an inverted angle te the upper plane 22. As a resuit of this as with the same amount of displacement the fîrst end of the rail-camping plate rises more than the ends of parallel clamping plates or clamping plates at an inverted angle, the use of a shorter and thinner railclamping plate 20 is suffîcient to create the same magnitude of clamping force. This results in a saving of material and, ultimately in a réduction of production costs.According to this récognition, the aforementionec advantages corne into effect if the angle between the railclamping plate 20 and the upper plane 22 of the reinforced concrète sleeper 14 is at least 5 degrees, preferably 5 to 20 degrees, even more preferably 10 to 15 degrees.According to expérience, in the case of angles in excess of 20 degrees it is difficult or impossible to get the rail mounting device 10 from fîrst state to second state.

The rail-clamping plate 20 is fixed to the anchoring element 18, as a resuit the rail mounting device 10 is taken from the fîrst state to the second state.In the case of a preferred embodiment the rail-clamping plate 20 is fixed to the anchoring element 18 with the flange 29 presented previously in such a way that the rail-clamping plate 20 is pushed towards the rail 12 up until the second end of the rail-clamping plate 20 gets behind the flange 29 (see figure 2b).Optionally the rail-clamping plate 20 may be fixed with a rétention lock containing a dépréssion 30a and a protrusion 30b, as can be seen in figure 4b, or an embodiment is conceivable in the case of which the rail-clamping plate 20 is fixed to the anchoring element 18 n, etc.

fixing of the rail 12 the device 10 is taken from second state to the way shown in figure 5b, for example, so that the head of the in another way, such as with a p:

In order to release the fîrst state by using the tool 40 in tool 40 is placed on the rail 12 and the fîrst end of the rail-clamping plate 20, then the handle of the tool 40 is tumed in the app Opriate direction. As a conséquence of the force exerted on the fîrst end of the rail-clamping pl second end of the rail-clampin late 20 the protrusion 30b pops out of the dépréssion 30a (or the g plate 20 jumps over the flange 29), and the rétention lock is

-9llI mounting device 10 according to the invention is that there is specially shaped rail-clamping plate, which significantly reduce upper plane 22 of the reinforced concrète sleeper 14, it is released.

The advantage of the ra no need for a base plate nor for a the production costs.A further ac vantage is that by appropriately selecting the angle between the rail-clamping plate 20 and the sufficient to use arail-clamping plate 20 of maximum 6 mm thickness, which may be produced from sheet steel using a sheet cutting processquickly and cost-effectively as compared to the existing solutions.

As the rail-clamping plate 20 does not rest directly upon the reinforced concrète sleeper 14 anywhere, the pitting effect that significantly reduces the fixing effect can be avoided, due to which the lifetime can be significantly extended.

In terms of implémenta ion, the amount of material used, the price of production of the materials used, the speed and simplicity of installation and construction, the rail mounting device 10 according to the invention ’epresents a signifïcant advance as compared to the solutions according to the state of the art.

Other alternative solutions as compared to the embodiments presented here will be apparent to a person skilled in the art without departing from the scope of protection determined by the attached daims.
