Fig.

1 to 11, the variable-rail pad 10 for railway rail according to an embodiment of the present invention includes a main body 20 and a check valve 30. As shown in FIG.

In this case, the resin injection port 21 and the air discharge port 23 are formed opposite to each other on both side edges of the main body 20, and the resin R to be injected through the resin injection port 21 is stored therein A portion 22 is formed.

The main body 20 may have various shapes such as a polygonal shape and an elliptical shape in addition to the shapes shown in the drawings. In the present invention, the main body 20 may be formed of two pieces of quadrangular shapes, An example in which the sheet is closely contacted and the outer end is formed through heat fusion will be described.

That is, the main body 20 cuts the two transparent resin sheets into a desired shape, closely adheres to each other, and then fuses the outer ends except the resin injection port 21 and the air outlet 23, And the storage unit 22 is formed in a predetermined space that can be stored.

The outer end of the main body 20 except for the resin injection port 21 and the air outlet 23 is adhered through high-frequency bonding or ultrasonic bonding in addition to the above-described thermal fusion bonding method, It is also possible to form the storage portion 22 of the predetermined space that can be stored.

At this time, the resin injection port 21 of the main body 20 has a predetermined width and diameter, and protrudes outward from one side edge of the main body 20 by a predetermined length, and the resin R flows back inside A check valve 30 is provided.

In the present invention, the resin injection port 21 is formed at one side edge of the main body 20 so as to be disposed outwardly when interposed between the sleepers 1 and the rails 2.

That is, the resin injection port 21 is formed so as to communicate with the storage part 22 while being disposed outwardly from one side edge of the main body 20, so that the resin R can be supplied to the storage part 22 .

At this time, the check valve 30 effectively blocks the resin R injected into the storage part 22 in the main body 20 from being discharged to the outside through the resin injection port 21. [

In other words, since the reverse flow of the resin R is blocked through the check valve 30 in the present invention, the structure is simplified and the variable pad 10 for a railway rail can be easily manufactured. 22 can be stably prevented from flowing backward.

In addition, a resin feeding device (not shown) having a trapezoidal or funnel shape is selectively mounted on the end of the resin injection port 21 to smoothly supply the resin R, and the resin feeding device is provided with a press- So that the resin R can be smoothly injected into the storage portion 22 in the main body 20.

At this time, the resin (R) to be injected into the storage part 22 in the main body 20 is any one or a mixture of two or more materials selected from urethane resin, epoxy resin and urea resin and has a viscosity of 250 to 350 mPa.s.

If the viscosity is less than 250 mPa.s, the time for completely supplying the resin to the storage part 22 in the main body 20 is delayed, When the viscosity exceeds 350 mPa.s, it is preferable that the resin has a viscosity of 250 to 350 mPa.s because it is difficult to inject the resin smoothly.

In order to improve the rigidity and the curing rate of the resin (R), another additive (A) may be mixed.

In addition, the main body 20 may be made of a nonwoven fabric or a fabric such as a nonwoven fabric so as to fix and support the sleepers 1 and the rails 2 with the slip prevention.

That is, the main body 20 is made of a nonwoven fabric or a fabric different from the variable pads made of conventional synthetic resin, and can be slid through the outer surface of the nonwoven fabric or the fiber during the installation work of the variable- The adhesive force between the sleepers 1 and the rails 2 can be improved by the resin flowing through the micro voids or gaps formed in the nonwoven fabric or the fibers themselves.

In addition, since the variable padding 10 for a railway rail is made of a nonwoven fabric or a fabric made of fibers, it is possible to prevent the air layer from being formed in the main body 20, and to accelerate the curing speed of the resin due to the automatic inflow of outside air have.

Meanwhile, the air outlet 23 has a predetermined width and diameter, and is formed to protrude outward from the other side edge of the main body 20 by a predetermined length.

In the present invention, the air outlet 23 is located on the other side of the other side of the main body 20 so as to be disposed outwardly between the cabin 1 and the rail 2 in the same manner as the resin injection port 21 .

That is, the air outlet 23 is disposed at the other side edge of the main body 20 and communicates with the storage portion 22 in the main body 20, so that the resin (R So that the air in the storage part 22 can be easily discharged to the outside.

At this time, as shown in FIG. 6, the air outlet 23 may be formed in such a shape that its width gradually decreases from one side coupled to the main body 20 to the other side opposite thereto.

The air existing in the storage part 22 of the main body 20 can be rapidly discharged and the resin R can be quickly injected into the storage part 22 in the main body 20. [ Therefore, the time for installing the variable-angle pad 10 for a railway rail according to the present invention between the sleeper 1 and the rail 2 can be remarkably shortened.

2 to 5, in the variable padding 10 for a railway rail according to another embodiment of the present invention, the air outlet 23 formed at the other side edge of the main body 20 And an air discharge port closing portion 40 for preventing the resin R from flowing to the outside by sealing the air discharge port 23.

At this time, two or more of the air discharge port closing portions 40 may be thermally fused to the inner surface of the air discharge port 23 with a gap therebetween, and may be formed of a metal material such as wire.

The air discharge port 23 is also twisted together when the air discharge port closing unit 40 formed of a metal material such as wire is twisted so that the air discharge port 23 can be completely closed, 23 or the air discharge port closing portion 40 need not be knotted by a string or a separate device.

Therefore, the operation for closing the air outlet 23 is simple, and the time for installing the variable-padding 10 for a railroad rail, to which the present invention is applied, between the railroad tie 1 and the rail 2 is significantly shortened .

At this time, the air outlet 23 is formed of a non-woven material so that air is allowed to pass therethrough and the resin is prevented from leaking by the air outlet closing part 40.

It is noted that the air outlet port closing part 40 may be coupled to the air outlet port 23 through high frequency bonding or ultrasonic bonding in addition to the heat fusion method.

In addition, the resin injection port 21 and the air discharge port 23 of the main body 20 are positioned at diagonal edges on both sides of the main body 20, and the resin R is injected into the storage part 22 of the main body 20 It is possible to prevent the resin R from being discharged from the air outlet 23 of the main body 20.

1 and 2, the resin inlet 21 of the main body 20 is located on the side of the main body 20 and the resin injection port 21 of the main body 20 is not located on the straight line. The air outlet 23 is formed at a lower left end (i.e., one side edge) of the main body 20, and the air outlet 23 is formed at the upper right end of the main body 20 When the resin R is injected into the storage portion 22 in the main body 20 through the air outlet 21 of the main body 20 and the resin R moves to the outside through the air outlet 23 of the main body 20 It is possible to suppress the discharge as much as possible.

12 and 13 (a), the shape maintaining means 80 is further integrally installed through heat fusion in the vertical direction along the outer peripheral surface of the main body 20 in the present invention, So that the main body 20 itself is retained in a rectangular housing shape by the shape retaining means 80 as another main technical component.

At this time, the shape maintaining means 80 is formed by molding a resin sheet or a synthetic resin having a thickness larger than that of the main body 20 made of a resin sheet such as a relatively thin transparent vinyl or the like, And is integrally fixed to the outside of the main body 20 through heat fusion.

A resin injection hole insertion groove 81 and an air exhaust hole insertion groove 82 are formed at both side edges of the shape maintaining means 80 when the shape maintaining means 80 is formed in a rectangular frame shape having upper and lower surfaces as described above, The resin injection port insertion groove 81 and the air discharge port insertion groove 82 are formed in the main body 20 in such a manner that the main body 20 is positioned inside the shape retaining means 80 in the shape of a rectangular frame and heat- The resin injection port 21 and the air discharge port 23 formed on both side edges of the shape maintaining means 80 are inserted into the resin injection port insertion groove 81 and the air discharge port insertion groove 82, So that it can be smoothly protruded outward.

The height of the shape maintaining means 80 is determined by the height of the clearance between the rail 2 and the sleepers 1. The height of the rail 2 generated when the rail 2 is installed on the top of the sleepers 1, It is preferable to have a height of 3 to 7 mm in view of the clearance height between the sleepers 1 and the sleepers 1.

The variable padding 10 for a railway rail in which the shape maintaining means 80 is integrally fixed to the outside of the main body 20 through heat fusion as described above is inserted between the rail 2 and the sleepers 1 And the resin R or the resin R containing the additive A is injected into the reservoir 22 in the main body 20, The outer surface of the main body 20 has a shape in which the resin R or the resin R containing the additive A is integrally adhered to the shape maintaining means 80 by thermal fusion The upper and lower surfaces of the main body 20 are connected to the bottom surface of the rail 2 and the upper surface of the sleeper 1, And has a flat shape in the horizontal direction. Therefore, after the resin is finally cured, Body 20 maintains an almost perfect rectangular enclosure shape as shown in (b) of Fig.

The shape retaining means 80 is formed by molding a resin sheet or a synthetic resin having a rectangular frame shape whose upper and lower surfaces are opened by a thicker resin sheet than the main body 20 made of a resin sheet such as a relatively thin transparent plastic sheet as described above The height is freely adjusted corresponding to the height of the clearance between the rail 2 and the sleepers 1.

On the other hand, the method of integrally connecting the shape maintaining means 80 to the main body 20 is not limited to the above example, and other examples can be presented in a large amount.

For example, the upper and lower ends of the main body 20 made of a transparent resin sheet are placed on the upper and lower surfaces of the shape maintaining means 80, which are made to have a rectangular frame shape as shown in FIG. 14, The upper and lower end contact portions of the main body 20 having a state of being in contact with the upper and lower surfaces of the main body 20 and the main body 20 are integrally fixed by thermal fusion, Shape.

In this case, the resin injection port 21 for injecting resin into the storage portion 22 formed between the shape maintaining means 80 and the main body 20 so as to be able to magnetize the resin, The air discharge port 23 for discharging the air may be installed or formed directly on both side edges of the shape maintaining means 80 so as to communicate with the storage portion 22. [

In addition, in the present invention, a core portion 50 is further provided in the storage portion 22 for securing the structural stability of the main body 20. [

The core portion 50 includes a nonwoven fabric or the like and is accommodated before the outer peripheral end of the main body 20 is integrally thermally fused or the like and the central portion of the storage portion 22 in the main body 20 The edge portion of the core portion 50 may be fixed in the storage portion 22. [

That is, the edge portion of the core 20 is formed integrally with the two resin sheets constituting the main body 20 through the core portion 50 and then the core portion 50 is integrally formed with the main body 20 The storage unit 22 can be stably positioned.

When the core portion 50 is stably positioned in the storage portion 22 of the main body 20 in the course of injecting the resin R into the storage portion 22 in the main body 20, (50) does not move.

The core part 50 fixed in the storage part 22 of the main body 20 functions as a skeleton and a skeleton of the main body 20 and is installed in the storage part 22 of the main body 20 And is integrated with the main body 20 as the injected resin R hardens.

The core member 50 increases the rigidity of the main body 20 so that the variable padding 10 for a railway rail to which the present invention is applied is installed between the railroad tie 1 and the rail 2 In this case, the structural stability can be secured.

In addition, since the core part 50 has a mesh structure, the core part 50 has a plurality of holes spaced from each other.

Since the resin R hardened in the plurality of holes formed in the core portion 50 serves as a bridge between the resin R cured at the upper portion and the lower portion of the core portion 50 with reference to FIG. The bonding force between the inner surface of the main body 20 and the core material portion 50 is increased so that the resin R can be cured in a stable form.

In addition, the main body 20 and the core portion 50 may be partially combined with each other as shown in Figs. 3 and 5.

Particularly, when the main body 20 and the core member 50 are partially coupled to each other, the stability of the connection between the main body 20 and the core member 50 can be secured, The resin R injected into the storage portion 22 in the main body 20 can be injected into the storage portion 22 in a uniformly distributed manner through the heat fusion portion without being concentrated to any one place.

At this time, the main body 20 and the core member 50 can be joined by heat fusion, high frequency bonding, ultrasonic bonding or the like.

The following description will be made with reference to an embodiment of a variable-rail pad for a railway constructed as described above.

First, a core portion 50 is interposed between two transparent resin sheets to be cut out in a rectangular plate shape, then the edge portion is thermally fused to form a storage portion 22 in which the resin R can be stored Thereby forming the main body 20.

A resin injection port 21 is connected to one side of the storage unit 22, that is, at one side edge of the main body 20 in communication with the storage unit 22 and a check valve 30 is installed therein. The variable padding 10 for the railway rail is completed when the air outlet 23 connected to the other side of the storage part 22 is connected to the other side edge of the air conditioner 20 and the air outlet port 23 having the air outlet closing part 40 is installed therein .

Here, the completion order of the variable pads 10 for the railway rail may be different from that described above.

That is, the main body 20 of the variable-rail pad 10 for railway is provided with a resin injection hole insertion groove 81 and an air discharge hole insertion groove 82 formed on both side edges thereof. The outer peripheral surface of the main body 20 is thermally fused to the inner surface of the shape retaining means 80 having a rectangular frame shape as shown in Figs. 12 and 13 (a) and 13 (b) The variable padding 10 for a railway rail can be completed through a method of integrally installing the variable padding 10.

In addition, after the core member 50 is interposed on the inner surface of the shape retaining means 80 of the rectangular frame shape in which the resin injection port 21 and the air outlet 23 are directly formed or formed on both side edges, The upper and lower ends of the main body 20 made of a transparent resin sheet are placed on the upper and lower surfaces of the holding means 80 and the upper and lower ends of the main body 20 having the state of being in contact with the upper and lower surfaces of the shape holding means 80 The upper and lower contact portions are integrally fixed to each other through thermal fusion so that a storage portion 22 having a predetermined volume capable of storing the resin R between the shape maintaining means 80 and the inner surface of the main body 20 The shape holding means 80 and the main body 20 have a hollow box shape.

A check valve 30 is provided in the resin injection port 21 provided at one side edge of the shape maintaining means 80 having a rectangular frame formation and the check valve 30 provided at the other side edge of the shape maintaining means 80 The variable padding 10 for a railway rail can also be completed by a method of installing an air outlet closing portion 40 in the air outlet 23. [

Next, the state of use of the variable pads for a railway rail constructed as described above will be described.

First, a variable padding 10 for a railway rail is mounted on an upper part of a sleeper 1 installed on a railway, and then the height of the rail 2 is set in the main body 20 of the railway rail 10 A resin R mixed with the resin R or the additive A is supplied to the storage portion 22 formed between the main body 20 and the shape retaining means 8.

That is, after the variable-padding 10 for the railway rail is mounted on the upper part of the sleeper 1, the resin (R) is inserted through the resin injection port 21 provided at one side edge of the main body 20 or the shape- ) Or the resin (R) in which the additive (A) is mixed is injected.

The resin R mixed with the resin R or the additive A injected into the reservoir 22 through the resin injection port 21 is supplied to the reservoir 22 while pushing the air remaining in the reservoir 22 The entirety of the variable padding 10 for a railway rail is always formed by a shape holding means 80 formed of a resin sheet or a synthetic resin which has a high elasticity and is thicker than the main body 20, .

Therefore, the height of the main body 20 of the variable padding 10 for railway rail is automatically regulated to correspond to the height between the rail 2 and the sleepers 2, Since the shape of the main body 20 is always maintained in a substantially rectangular shape regardless of the height between the rails 2 and the sleepers, the supporting force of the variable-length pads for rail rails is greatly increased, ), It is possible to completely prevent the variation of the installation position of the variable pads for the railway rail by vibration or sliding.

Next, the air existing in the storage part 22 is quickly discharged to the outside through the air outlet 23, and only the resin R is left in the storage part 22.

After the injection of the resin into the storage part 22 is completed, the air outlet opening part 40 is twisted so that the air outlet 23 is closed, so that the resin R or the additive A) mixed resin R does not flow out to the outside.

Thereafter, the resin (R) mixed with the resin (R) or the additive (A) filled in the storage part (22) is cured and fixed to the sleeper (1) through a separate fixing device Next, the rails 2 are mounted on the upper portion of the variable-rail pad 10 for railway.

Next, it can be seen that the variable-strength pad 10 for the railway rail can be mounted not only between the rail 2 and the sleepers 1 but also between the sleepers 1 and the girders as shown in Fig.

The variable padding 10 for the railway rail to which the present invention is applied is placed on the upper part of the girder and then the resin padding 10 is inserted into the storage part 22 of the variable padding 10 for the railway rail, R) or the additive (A) are mixed.

That is, after the variable padding 10 for the railway rail is mounted on the upper portion of the girder, the resin R mixed with the resin R or the additive A through the resin injection port 21 is stored in the storage portion 22, .

The resin R injected into the reservoir 22 through the resin injection port 21 presses the air remaining in the reservoir 22 and fills the interior of the reservoir 22.

Since the air remaining in the storage part 22 is quickly discharged to the outside through the air outlet 23, the resin R or the resin R mixed with the additive A is stored in the storage part 22, Only.

The air outlet opening 40 is twisted so that the air outlet 23 is closed so that the resin R mixed with the resin R or the additive A injected into the storing portion 22 is prevented from flowing out do.

Thereafter, the resin (R) mixed with the resin (R) or the additive (A) filled in the storage portion (22) is cured and then the variable rail pad (10) (1), and then the rail (2) is mounted on the upper portion of the variable padding (10) for the railway rail.

9 shows that the resin injection port closing part 60 is applied to the inside of the resin injection port 21 instead of the check valve 30.

The resin injection port closing part 60 is formed of metal such as wire or the like in the same manner as the air outlet port closing part 40 of the air outlet port 23 described above and two or more are formed on the inner surface of the resin port 21 And are thermally fused at predetermined intervals.

Therefore, when the resin R injected with the resin (R) or the additive (A) is injected into the storage part 22 and then the resin injection port closing part 60 is twisted, the resin injection port 21 The resin injection port 21 is completely sealed by the tightening action of the resin injection port seal 60 so that the resin R injected into the storage portion 22 is injected into the resin injection port 21 (That is, reverse flow) to the outside can be effectively prevented.

In addition, since it is not necessary to knot the resin injection port 21 or the resin injection port closing part 60 through a string or a separate device, the operation for sealing the resin injection port 21 is simple, The time for installing the variable-length pad 10 'for the railway rail between the sleeper 1 and the rail 2 can be remarkably shortened.

10 and 11 show a fixing hole 20a formed at the edge of the main body 20 to integrally fix the railroad variable pads 10 and 10 'to which the present invention is applied, to the girder and the rail 2 will be.

In this case, a plurality of railroad variable pads 10, 10 'may be seated on the upper surface of the girder at regular intervals, and then the rails 2 may be mounted on the upper surface thereof.

Thereafter, the rail 2 is fixed to the girder through the fixing device 70, and the bolts 71 of the fixing device 70 are installed on the girder in the form of passing through the fixing holes 20a of the main body 20 So that the railroad flexible pads 10 and 10 'to which the present invention is applied can be stably fixed to the rail 2 and the girder.

At this time, the fixing device 70 can be applied to those generally used for fixing the girder and the rail 2.

When the variable pads 10 and 10 'for railway to which the present invention is applied are stably fixed to the girder and the rail 2 as described above, the vibration of the railway variable pads 10 and 10 Can be prevented from being completely displaced and the stable connection of the railway variable pads 10, 10 'and the girder and the rail 2 can be maintained constantly, Stability can be ensured.

Although the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Which will be apparent to those skilled in the art.
