Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail installation method and installation structure that do not need to be fixed with dog nails or bolts, and particularly rail installation suitable when a derailment prevention rail is laid along a traveling rail. It relates to a method and an installation structure.

2. Description of the Related Art Generally, when laying a railroad track, in a section where the track forms a curved line within a predetermined radius,
In order to prevent wear and derailment of the traveling rail along the track centerline side (inner side) of the traveling rail having the smaller radius of curvature (inner rail side) of the two traveling rails, Is required to be laid. Also,
Such derailment prevention rails need to be laid not only on the curved sections but also on bridges, embankments, and railroad crossings that are recognized as being particularly necessary.

FIG. 19 shows a rail installation structure in a section in which a conventional derailment prevention rail of this type is laid, and reference numeral 1 in the drawing denotes one traveling rail. The traveling rail 1 is mounted on the track pad 3 on the sleeper 2 and fixed to the sleeper 2 by the dog nail 4 and the screw spike 7 that press the lower flange 1b. When the derailment prevention rail 5 is laid along the traveling rail 1, the derailment prevention rail 5 is adjacent to the sleeper 2 so that the upper surface 5a is higher than the upper surface 1a of the traveling rail 1 by a predetermined dimension. It is mounted on the height adjusting member 6 arranged in the same manner, and is fixed to the sleeper 2 by the dog nail 4 and the screw spike 7 which are similarly tightened so as to press the lower flange 5b. Further, the traveling rail 1 and the derailment prevention rail 5 are kept at a constant interval by a chock bolt 8 inserted between the webs 1c and 5c at predetermined intervals, a spacer (not shown) and bolts, nuts, etc. As a result, the rail heads are embedded on the paved surface 9 of asphalt concrete or the like so that only the rail heads are exposed.

[0004]

By the way, in the above-mentioned conventional rail installation structure, the rail is sunk downward due to gravity when the vehicle is passing, and a lateral force (lateral pressure) is applied to the rail.
, The rail tilts inward and outward, and receives a destructive effect such as vibration of the entire track. Asphalt concrete has poor adhesiveness and elasticity with the rail, cracks immediately, and there is no rail holding force. Therefore, the traveling rail 1 and the derailment prevention rail 5 are both attached to the lower flange 1.
In a and 5a, it is substantially the same as the state in which it is only fixed to the sleeper 2 by the dog nail 4 and the screw spike 7.

In such a state, in the above conventional rail installation structure, when the vehicle passes, the derailment prevention rail 5 integrated with the traveling rail 1 also receives the centrifugal force from the wheels. As a result, due to long-term use, the chock bolt 8 or the bolt may be stretched or loosened between the bolts and nuts, so that the derailment prevention rail 5 gradually tilts in a direction away from the traveling rail 1. There is a drawback, and therefore, there has been a problem that a lot of labor is required for regular maintenance work such as inspection of the rail and retightening or replacement of the chock bolt 8 and the like. In addition, the traveling rail 1 and the derailment prevention rail 5 are
Since they are fixed at points on the sleepers 2 which are arranged intermittently, relatively large vibration is generated, and particularly when the paving material is concrete, noise reverberates in the concrete and it is further noisy. There was a problem. Further, there is a problem that the rails 1 and 5 are likely to be unevenly worn due to long-term use, and thus the service life of the rails 1 and 5 is shortened.

The present invention has been made to solve the problems of the conventional rail installation structure described above. The derailment prevention rail does not tilt even after long-term use, and maintenance is facilitated. At the same time, the service life of the traveling rail and derailment prevention rail can be extended, the ride comfort and safety are excellent, and the rail installation structure that does not need to be fixed with dog nails or screw spikes is efficiently formed. An object of the present invention is to provide a rail installation method and a rail installation structure.

In the rail installation method according to any one of claims 1 to 3 and the rail installation structure according to claim 15, since the vibration absorbing plate is laid on the bottom surface of the recess, the vibration absorbing plate contracts when passing the train. Then, the traveling rail is properly sunk, which improves the ride comfort of the train and absorbs vibrations well. In particular, when the vibration absorbing plate is laid, an adhesive is applied to the bottom surface of the concave portion to bond and fix the vibration absorbing plate, so that the bottom surface of the concave portion and the vibration absorbing plate are joined, and the concave portion is made of polyurethane. In addition to rail restraint from the side, rail restraint from the bottom of the recess is done, restraining force against rail axial force generated by rail temperature contraction increases, and stress concentration on rail bifurcation etc. due to thermal contraction of rail is sure This prevents the damage and prevents the damage.

Further, an adjusting plate whose height is adjusted so that each level of the traveling rail and the derailment prevention rail becomes a predetermined level is provided at a bottom surface laying position of each of the traveling rail and the derailment prevention rail. Since it is placed on the vibration absorbing plate along with it, even if the height of the bottom surface of the recess is uneven, it is possible to ensure high accuracy of the running surface by the adjusting plate, and the degree of freedom of height adjustment is increased. Increase. Moreover,
Adjust the adjustment plate along the bottom surface laying position of each rail,
Since they are placed at intervals (for example, placed at 1-2 m intervals),
These adjusting plates form a space between the bottom surface of each of the traveling rail and the derailment prevention rail and the vibration absorbing plate, and a polyurethane filling layer is formed in the space by injecting polyurethane into the recess later. The adjusting plate is fixed to the vibration absorbing plate, and the traveling rail itself and the derailment prevention rail itself are firmly fixed.

Therefore, the adjusting plate need only be placed on the vibration absorbing plate, the construction is simple, and the bolt,
Compared to the conventional height adjustment that was performed while adjusting the fastening metal fittings such as nuts, dog nails, tie plates and sleepers, positioning can be performed accurately and easily in 1 mm units. In addition, since polyurethane having self-leveling properties is used when pouring polyurethane into the concave portion, a horizontal surface can be obtained without leveling the upper surface separately, so that the work is generally easy.

In addition, in the obtained rail installation structure, the running rail and the derailment prevention rail, which are spaced from each other by the spacer, are provided in the recess formed in the upper surface of the base of the track, and the entire length of the recess is provided. Since the entire surface of the web and the lower flange are respectively restrained by polyurethane, the distance between the traveling rail and the derailment prevention rail is not affected even after long-term use, and the derailment prevention rail does not tilt. Further, in the conventional rail installation structure using sleepers or dog nails, since the rail is intermittently supported at points, relatively large vibration is generated and uneven wear is likely to occur on the rail. In the present invention, since the rail is continuously supported on the surface by the polyurethane with which the recess is filled, the occurrence of the vibration can be suppressed, and there is no risk of uneven wear of the rail.

Further, as a result of supporting the traveling rail and the derailment prevention rail in the recess formed on the upper surface of the foundation, there is no need to use fasteners such as dog nails and screw spikes as in the conventional case, The maintenance and inspection work of these rails can be significantly reduced, and various shapes of rails can be used.

Furthermore, since the lower flange of the traveling rail and the entire surface of the web are constrained by polyurethane, synergistic vibration absorption is also possible from this point, noise is extremely low, and the traveling rail and derailment prevention rail have a long service life. It is also possible to improve the ride comfort and safety.

Particularly, in the invention described in claim 2,
Since the connecting end of the traveling rail was left to be fixed with the polyurethane and the connecting end and the connecting end of the connecting traveling rail similarly fixed with polyurethane were connected in the recess, the rail position As a result of being fixed, connection is easy, and rail position adjustment after connection is not required.

Further, in the invention described in claim 3,
After the connection ends of the traveling rail and the connection traveling rail are connected to each other in a state where the traveling rail and the derailment prevention rail are placed on the adjustment plate, the traveling including the connected connection end portion. Since the rail is fixed by the polyurethane, the injection of polyurethane does not have to be divided into the connection end portion and the traveling rail main body or the derailment prevention rail main body, and can be performed at once. Therefore, there is no complication in the procedure for the injection of polyurethane.

Next, in the rail installation method according to any one of claims 4 to 6 and the rail installation structure according to claim 17, since the vibration absorbing plate is laid on the bottom surface of the recess, the vibration absorbing plate is passed when the train passes.

Has the effect.

Further, since the adjusting plate whose height is adjusted so that the level of the traveling rail becomes a predetermined level is placed on the vibration absorbing plate along the lower surface laying position of the traveling rail, the recessed portion is formed. Even if the height of the bottom surface is non-uniform, the adjustment plate can ensure high accuracy of the running surface, and the degree of freedom in height adjustment increases. Moreover, since the adjusting plates are placed at intervals (for example, at an interval of 1 to 2 m) along the lower surface laying position of the traveling rail, these adjusting plates allow the space between the bottom lower surface of the traveling rail and the vibration absorbing plate. A space is formed, and a filling layer of polyurethane is formed in the space by injecting polyurethane into the recess later,
The adjusting plate is fixed to the vibration absorbing plate, and the traveling rail itself is also firmly fixed.

Therefore, the adjusting plate need only be placed on the vibration absorbing plate, the construction is simple, and the bolt,
Compared to the conventional height adjustment that was performed while adjusting the fastening metal fittings such as nuts, dog nails, tie plates and sleepers, positioning can be performed accurately and easily in 1 mm units. . Moreover, when pouring polyurethane into the recesses, since polyurethane having a self-leveling property is used, a horizontal surface can be obtained without leveling the upper surface separately, and therefore the work is generally easy.

In addition, in the obtained rail installation structure, the traveling rail is constrained by polyurethane in the recess formed in the upper surface of the base of the track over the entire length of the recess and the entire web and lower flange. Therefore, even if it is used for a long period of time, it does not affect the holding of the traveling rail. Further, in the conventional rail installation structure using sleepers or dog nails, since the rail is intermittently supported at points, relatively large vibration is generated and uneven wear is likely to occur on the rail. In the present invention, since the rail is continuously supported on the surface by the polyurethane with which the recess is filled, the occurrence of the vibration can be suppressed, and there is no risk of uneven wear of the rail.

Further, since the traveling rails are supported in the recesses formed on the upper surface of the foundation, there is no need to use fasteners such as dog nails and screw spikes as in the prior art, so maintenance of these rails is not required. It is possible to significantly reduce the inspection work, and various shapes of rails can be used for these rails. Further, since the vibration absorbing plate is laid on the bottom surface of the recess, the vibration absorbing plate contracts when the train passes and the traveling rail appropriately sinks, so that the riding comfort of the train is improved and the vibration is absorbed.
Furthermore, since the lower flange of the traveling rail and the entire surface of the web are constrained with polyurethane, synergistic vibration absorption is possible from this point as well, noise is extremely low, and the service life of the traveling rail is extended. It has excellent riding comfort and safety.

Further, in the invention according to claim 5, the running rail is fixed with the polyurethane while leaving the connecting end portion of the running rail, and the connecting end portion of the connecting running rail also fixed with the polyurethane. Since the rail and the portion are connected in the recess, the rail position is fixed, so that the connection is easy and the rail position adjustment after the connection is unnecessary.

Further, in the invention described in claim 6,
With the traveling rail placed on the adjustment plate, after connecting the connecting ends of the traveling rail and the connecting traveling rail to each other, the traveling rail including the connected connecting end is made of the polyurethane. Since it is fixed, the injection of polyurethane does not have to be divided into the connection end portion and the traveling rail main body, and can be performed at once. Therefore, there is no complication in the procedure for the injection of polyurethane.

The above steps in the inventions of claims 1 to 6 are different from the case where the steps are sequentially performed on the entire rail and the steps different from the adjacent steps at the respective positions in the length direction of the rail. It may be done. Therefore, the time-series interpretation of each of the above steps may be a step of a specific rail as a whole or a step of installing a part of the rail, and is broadly understood. Although the standard length of the rail is generally 25 m, these may be welded and connected in advance to a required length and installed as the running rail or derailment preventing rail of the present invention. The length of the derailment prevention rail is not limited to the specified dimension and is arbitrary.

Further, in the invention described in claims 1 to 6, 15 and 17, the concave portion for accommodating the traveling rail and the derailment prevention rail or the concave portion for accommodating the traveling rail is, for example, on the ground which is a base portion of the track. It is also possible to form it by embedding a U-shaped member made of steel plate or cast metal, but if you use an integral concrete slab in which two recesses that form the track are formed, both It is possible to easily adjust the distance between the rails and lay it with high accuracy. Such a concrete slab can be constructed by cast-in-place construction using a formwork, but it is also possible to use precast concrete produced in a factory in advance. In this case, the installation structure according to any one of claims 1 to 3 or 15 is formed in one of the recesses on the upper surface of the concrete slab, and the installation structure according to any one of claims 4 to 6 or 17,
It is preferably formed in the other recess. Further, in a bridge or the like made of a steel structure, the recess may be formed, for example, by providing a U-shaped steel groove formed by a steel plate or a casting in the bridge floor plate portion that is the foundation of the track. .

Separately prepared, adjust the height dimension so that each level of the traveling rail and the derailment prevention rail becomes a predetermined level, and install the underside of each of the traveling rail and the derailment prevention rail. May be placed on each of the above vibration absorbing plates at intervals. Further, since the level difference between the traveling rail and the derailment prevention rail is always constant, an adjustment plate integrally formed with the traveling rail adjustment plate and the derailment prevention rail adjustment plate is prepared, Adjust the height of the integrated adjustment plate so that the rails and the derailment prevention rails reach the specified levels, and place them at intervals along the bottom surface of the travel rail and derailment prevention rail. Alternatively, it may be placed on the vibration absorbing plate.

Further, the connecting end portion of the traveling rail placed on the adjustment plate according to the third and sixth aspects and the connecting traveling rail installed in the recess and connected to the traveling rail are provided. In the step of connecting the traveling rails to be connected, it is preferable that the connecting traveling rails are already fixed with polyurethane except for the connecting end portions thereof. When the connected traveling rail is not fixed with polyurethane, the vibration absorbing plate laying process, the adjusting plate installing process, and the rail installing process must be completed and at least positioning for connection must be performed.

Further, in the present invention according to claim 7, the connecting end portions of the traveling rail and the connecting traveling rail are connected to each other.
Since the connection is made by welding in the recess, the conventional rail joints can be eliminated, good riding comfort with less vibration can be obtained, and shocks at the conventional rail joints can be eliminated, and the rail and track structure Is prolonged. Moreover, before injecting the polyurethane into the concave portion having the connecting end portion that is welded and connected, an adhesive is applied to the unlaid portion of the vibration absorbing plate on the bottom surface of the concave portion having the connecting end portion to cause the vibration. Since the absorbing plate is adhesively fixed, it has a similar structure to other polyurethane fixing points, eliminating the structural peculiarities at the rail welding part, and the vibration absorbing plate contracts when passing the train no matter where the running rail is taken. As the rail sinks properly, it makes the train more comfortable to ride and absorbs vibration well, improving the durability of the rail.

Further, in the present invention according to claim 8 and claim 16, first, the polyurethane is injected between the running rail and the side wall of the recess and between the derailment prevention rail and the side wall of the recess. The surface level of the polyurethane between the traveling rail and the side wall of the recess and between the derailment prevention rail and the side wall of the recess is approximately the same as the upper surface level of the base of the track. As a result, the injected polyurethane is prevented from passing through the traveling rail and the derailment prevention through the space formed by the adjusting plate between the bottom surface of each of the traveling rail and the derailment prevention rail and the vibration absorbing plate. Go around a little to the rail. In this case, the surface level of the polyurethane between the traveling rail and the derailment prevention rail is between the traveling rail and the recess side wall and between the derailment prevention rail and the recess side wall due to the viscosity and progress of curing of polyurethane. It does not rise to the same level as the surface level of the polyurethane during the period and stops at a fairly low position. In this state, since polyurethane is added between the traveling rail and the derailment prevention rail, the surface level of each polyurethane can be properly positioned at a predetermined position.

Moreover, the flow of polyurethane of polyurethane passing through the spaces formed between the bottom surfaces of the bottoms of the traveling rail and the derailment prevention rail and the vibration absorbing plate by the adjusting plate is from one direction side. Also, there is no possibility that air will enter the polyurethane. In addition, the obtained rail installation structure is such that the surface level of the polyurethane layer between the traveling rail and the derailment prevention rail can surely secure the depth required as a flange way of a wheel, and the traveling Since the surface level of the polyurethane layer between the rail and the side wall of the recess and between the rail for preventing derailment and the side wall of the recess is set to be substantially the same as the upper surface level of the base portion of the track, for example, concrete slab formation It also protects the side wall of the recessed portion.

Further, in the present invention according to claim 9, first, the polyurethane is injected between the recess side wall located outside the rail track and the traveling rail, so that the recess side wall and the traveling rail are connected to each other. The surface level of the polyurethane between the two is approximately the same as the upper surface level of the base of the track. As a result, the injected polyurethane is
It slightly goes around to the opposite side of the traveling rail through the space formed by the adjusting plate between the bottom surface of the bottom of the traveling rail and the vibration absorbing plate. In this case, the surface level of the polyurethane between the recess side wall inside the rail track located on the opposite side and the traveling rail is the same as the recess side wall located outside the rail track due to the viscosity of polyurethane and the progress of curing. It does not rise to the same level as the surface level of the polyurethane between it and the running rail, but rather comes to a standstill at a very low position. In this state, since polyurethane is added between the side wall of the recess on the inside of the rail track and the running rail, the surface level of each polyurethane can be properly positioned at a predetermined position.

Moreover, since the flow of polyurethane passing through the space formed between the bottom surface of the bottom of the traveling rail and the vibration absorbing plate by the adjusting plate is from one side,
There is no risk of air being mixed in the polyurethane. In addition, in the obtained rail installation structure, the surface level of the polyurethane between the recess side wall inside the rail track and the traveling rail can surely secure the depth required as the flange way of the wheel.

Further, in the present invention according to claim 10 and claim 18, the polyurethane is a urethane elastomer prepared by mixing a polyisocyanate prepolymer and an amine to obtain a final product. Yes, because 1 to 10% by weight of cork grains is included,
This is preferable because it is possible to more effectively suppress vibrations and noise that occur during traveling of the vehicle.

Further, in the present invention as set forth in claim 11, by adopting polyisocyanate dissolved in a solvent as a primer to be sprayed before injecting the polyurethane into the recess, the inner wall surface of the recess of the polyurethane, The adhesive strength to the vibration absorbing plate, the adjusting plate and the rail can be further increased.

Further, in the present invention as set forth in claims 12 and 19, since synthetic rubber or natural rubber is adopted as the vibration absorbing plate, it is well compatible with polyurethane and is generated during running of the vehicle. It is preferable because vibration and noise can be suppressed more effectively. In addition, an epoxy resin adhesive (e
Since it uses poxy resin adhesives), it can be surely adhered to the bottom surface of the recess.

Further, in the present invention as set forth in claim 13, since the adjusting plate is arranged so that a plurality of adjusting plates having the same thickness or different thicknesses are stacked and adjusted to a predetermined height, The adjustment can be performed by a combination of the adjusting plates, and it is not necessary to machine the thickness of the adjusting plate each time, and the positioning of the rail can be adjusted more accurately and easily than in the conventional case.

Further, in the present invention as set forth in claim 14 and claim 20, 1 particle of cork is added to the vibration absorbing plate.
Since the adjusting plate is contained in an amount of up to 20% by weight, and the adjusting plate is a cork plate, it has elastic properties of approximately the same level and is well compatible with polyurethane, and also has good compatibility with polyurethane. It has both sound absorbing property and sound absorbing property, and the workability is easy and the height can be easily adjusted.

BEST MODE FOR CARRYING OUT THE INVENTION First, as a first embodiment, an installation method and installation structure of a rail on the side on which a derailment prevention rail is laid in relation to claims 1 and 15 of the present invention will be described. 1 and 2 show a part of the side on which the derailment prevention rail is laid, in which reference numeral 10 is a concrete slab that serves as a base portion of the track, reference numeral 1
Reference numeral 1 is a traveling rail, and reference numeral 12 is a derailment prevention rail. The concrete slab 10 is wider than the track width of the traveling rail 11 and is formed in a plate shape that is continuous at least in the section where the derailment prevention rail 12 is laid. A recess 13 for accommodating the rail 12 and a recess 33 (see FIG. 9) for accommodating the other traveling rail on the right side are formed.

On the bottom surface of the recess 13, a vibration absorbing plate 14 made of a synthetic rubber plate or a natural rubber plate is provided.
1 and the derailment prevention rail 12 are continuously bonded and fixed via an adhesive layer 22 in the laying direction. The vibration absorbing plate 14 may be only a synthetic rubber plate or a natural rubber plate,
Considering the train load and riding comfort on the track, it is preferable to select a filler having a predetermined elastic coefficient by changing the composition and thickness of the filler such as cork powder. 1-20 cork grains
It is preferably contained in the range of% by weight. Further, height adjusting plates 15 and 16 made of cork plates are placed on the vibration absorbing plate 14 at intervals in the laying direction. Here, the adjustment plate 1 disposed below the derailment prevention rail 12
6 is formed thicker than the adjustment plate 15 so that the upper surface 12a of the derailment prevention rail 12 is higher than the upper surface 11a of the traveling rail 11 by a predetermined dimension. Then, on the plurality of adjusting plates 15 and 16, the traveling rail 1 is provided.
1 and a derailment prevention rail 12 are laid.

Here, the traveling rail 11 and the derailment prevention rail 12 have spacers 17 interposed between the webs 11b and 12b at a predetermined interval.
bolt 18 penetrating b, 12b and spacer 17
And a nut 19 screwed to the bolt 18 are integrated with each other while maintaining a distance therebetween.
Pipes 20 made of vinyl chloride are attached to the outer sides of the traveling rail 11 and the derailment prevention rail 12, respectively.

Then, 1 to 10% by weight of the cork powder is mixed in the concave portion 13, and the polyurethane 21 to which the curing agent is added is injected and cured.
The traveling rail 11 and the derailment prevention rail 12 are fixed. In this case, as the polyurethane (urethane resin), for example, polyisocyanate prepolymer,
A mixture containing 1 to 10% by weight of cork particles in a mixture with an amine can be preferably used. This mixture is injected into a predetermined place and hardens after a certain period of time. More effectively suppress.

Next, a rail installation method according to the first embodiment for obtaining the rail installation structure having the above configuration will be described with reference to FIGS. First, as shown in FIG. 3, after the adhesive 22 is applied to the bottom of the recess 13 of the concrete slab 10, the vibration absorbing plate 14 is adhesively fixed. As the adhesive 22, epoxy resin adhesives to which a curing agent is added can be preferably used. For example, if a polyamine or the like is added to a liquid prepolymer containing two or more epoxy groups as a curing agent to cure at room temperature and exert a strong adhesive force, it hardly shrinks even after curing and the film thickness of the adhesive layer. It is preferable because it has a characteristic that cracks do not occur even if it is large, and the adhesive force does not decrease, and the bottom surface of the recess 13 and the vibration absorbing plate 14 can be reliably bonded.

The width of the vibration absorbing plate 14 is smaller than the width of the bottom of the recess 13. This is the recess 13
This is because the bottom of the recess 13 is exposed on both sides of the vibration absorbing plate 14 with the vibration absorbing plate 14 adhered and fixed to the bottom of the polyurethane 21. Touches a part of the bottom of the recess 13 to wrap and firmly fix the vibration absorbing plate 14, and the polyurethane 21 itself also contacts the bottom of the recess 13 to increase the strength as a whole.

Next, from the upper surface of the vibration absorbing plate 14, the upper surfaces 11a of the traveling rail 11 and the derailment prevention rail 12,
The height dimension up to the level of 12a is rail 1
Measured at appropriate intervals in the laying direction of Nos. 1 and 12, and
As shown in FIG. 3, the adjusting plates 15 and 16 having thicknesses corresponding to the heights of the respective measurement points are placed on the vibration absorbing plate 14. That is, the adjusting plates 15 and 16 whose heights are adjusted so that the levels of the traveling rail 11 and the derailment prevention rail 12 become predetermined levels are provided at the bottom surface laying positions of the traveling rail 11 and the derailment prevention rail 12, respectively. Along the above, they are placed on each of the vibration absorbing plates 14 at intervals.

To adjust the height of the adjusting plates 15 and 16, a plurality of adjusting plates having the same thickness or different thicknesses, for example, adjusting plates having a thickness of 1 mm, 2 mm, 3 mm and 5 mm are prepared in advance. , These adjusting plates are combined and stacked at a predetermined height. As a result, it is not necessary to machine the thickness of the adjusting plate each time, and the positioning of the rail can be adjusted more accurately and easily than in the conventional case. Further, as the adjusting plate, it has both vibration absorption and sound absorbing properties, and has the same elastic characteristics as polyurethane, and is well-fitted,
A cork board which is easy to work is suitable.

In addition, the traveling rail 11 and the derailment prevention rail 1
Since the level difference from 2 is always constant, an adjustment plate in which the adjustment plate 15 for the traveling rail 11 and the adjustment plate 16 for the derailment prevention rail 12 are integrally formed is prepared. An integrated type adjusting plate whose height dimension is adjusted so that each level becomes a predetermined level is provided on the vibration absorbing plate 14 along the lower surface laying positions of the traveling rail 11 and the derailment prevention rail 12 at intervals. You may leave it.

Further, in parallel with this, the traveling rail 11 and the derailment prevention rail 12 are integrated by the spacer 17, the bolt 18 and the nut 19 in such a state that the distance between them is maintained. Rail length is generally 25 standard dimensions
However, it is preferable that these are integrated by welding and connecting them in advance to a desired length and then maintaining a mutual distance. Integrated traveling rail 11 and derailment prevention rail 1
A pipe 20 made of vinyl chloride is attached to the outer side of 2 by a spacer / horizontal position adjusting ring 23 and a wire or plastic band 24 (see FIG. 6) 24 wound at appropriate intervals. Then, as shown in FIG. 5, the traveling rail 11 and the derailment prevention rail 12 in which these pipes 20 are also integrated are placed on the adjusting plates 15 and 16.

Then, as shown in FIG. 6, a wedge member 25 made of cork is driven between the horizontal position adjusting ring 23 mounted on the pipe 20 and the side wall of the recess 13 to move the traveling rail 11 and the derailment prevention rail 12. Adjust the horizontal position of. After the positioning of the traveling rail 11 and the derailment prevention rail 12 is completed in this way, the wire and the plastic band 24 are removed.

Next, as shown in FIG. 7, a primer 26 for increasing the adhesive strength with the polyurethane 21 to be injected in a later step is sprinkled throughout the recess 13. As the primer 26, for example, methylene chloride, methylene dichloride or the like having 4,4'-diphenylmethane diisocyanate dissolved in about 20% by weight can be preferably used.

Next, the polyurethane 21 is injected between the traveling rail 11 and the side wall of the recess 13 and between the derailment prevention rail 12 and the side wall of the recess 13. Running rail 11
The polyurethane 21 is injected such that the surface level of the polyurethane 21 between the rail and the side wall of the recess 13 and between the derailment prevention rail 12 and the side wall of the recess 13 is the same as the upper surface level of the concrete slab 10. As a result, the injected polyurethane 21 is attached to the bottom surface of each of the traveling rail 11 and the derailment prevention rail 12 and the vibration absorbing plate 14.
A little between the traveling rail 11 and the derailment prevention rail 12 via a gap formed by the adjusting plates 15 and 16 between the traveling rail 11 and. In this case, the surface level of the polyurethane 21 between the traveling rail 11 and the derailment prevention rail 12 is
Due to the viscosity and the progress of curing of the polyurethane 21, the rail 1 between the traveling rail 11 and the side wall of the recess 13 and the derailment prevention rail 1
It does not rise to the same level as the surface level of the polyurethane 21 between the 2 and the side wall of the recess 13, but comes to a stop at a fairly low position.

In this state, polyurethane 21 is added between the traveling rail 11 and the derailment prevention rail 12, and the surface level of the polyurethane 21 between the traveling rail 11 and the derailment prevention rail 12 is adjusted to the head of the traveling rail 11. So that it is located at the bottom of the section. As a result, each surface level of the polyurethane 21 can be properly positioned at a predetermined position, and the polyurethane 21 can be filled in the recess 13. At the same time, since the polyurethane 21 has self-leveling property, a smooth horizontal surface is naturally formed on the upper surface. To be done.
Then, after a certain period of time, the polyurethane 21 is cured, whereby the installation structure of the traveling rail 11 and the derailment prevention rail 12 shown in FIGS. 1 and 2 is completed.

According to the rail installation structure and installation method having the above-described structure, the traveling rail 11 and the derailment prevention rail 12, which are held at a distance from each other by the spacer 17, serve as a concrete slab that serves as the foundation of the track. 10
Since the webs 11b, 12b and the lower flange are entirely constrained by the polyurethane 21 over the entire length in the recess 13 formed on the upper surface, the derailment prevention rail 12 does not tilt even after long-term use. Further, since the entire surfaces of both rails 11 and 12 are constrained by polyurethane 21, compared to the case where the rails are supported at intermittent points as in the conventional rail installation structure using sleepers or dog nails. Thus, the occurrence of vibration and the uneven wear of the rails 11 and 12 can be significantly reduced.

Furthermore, since the traveling rail 11 and the derailment prevention rail 12 are supported in the recess 13 formed in the upper surface of the concrete slab 10, there is no need to use sleepers or dog nails as in the conventional case. The maintenance and inspection work of these rails 11 and 12 can be greatly reduced, and various shapes of rails 11 and 12 can be used.

Further, as the polyurethane 21, polyurethane mixed with cork powder is used, and the recess 1
Lay the vibration absorbing plate 14 that serves as a vibration absorbing plate at the bottom of 3,
On the vibration absorbing plate 14, a cork adjusting plate 1 is further provided.
The running rail 11 and the derailment prevention rail 12 via 5 and 16
Since the and are mounted, it is possible to effectively suppress vibration and noise generated while the vehicle is traveling.

Further, according to the above-mentioned rail installation method, the bottom surface of the concave portion 13, the traveling rail 11 and the derailment prevention rail 1 are provided.
The height of the upper surface level of 2 is measured, and a plurality of adjusting plates 15 and 16 having a thickness dimension corresponding to the measured values are placed along the lower surface positions of the traveling rail 11 and the derailment prevention rail 12, respectively. Therefore, even if the height of the bottom surface of the recess 13 is not uniform, the adjustment plates 15 and 16 absorb the unevenness to ensure high accuracy of the running surface.

In addition, a plurality of adjusting plates 15 and 16 are arranged at predetermined intervals (for example, 1 to 2 m) in the laying direction of the rails 11 and 12.
As a result of being placed at a space, a space is formed between the rails 11 and 12 positioned between the adjusting plates and the vibration absorbing plate 14,
After that, by injecting the polyurethane 21 into the concave portion 13, a filling layer of the polyurethane 21 is formed in the space, the adjusting plates 15 and 16 are fixed to the vibration absorbing plate 14, and the traveling rail 11 itself and the derailment prevention rail 12 itself. It is firmly fixed. Therefore, the adjusting plates 15 and 16 need only be placed on the vibration absorbing plate 14, and the construction is simple, and the adjustment plates 15 and 16 can be mounted while adjusting the fasteners such as bolts, nuts, dog nails, tie plates and sleepers. Compared with height adjustment, positioning can be performed accurately and easily in units of 1 mm.

Further, the rail 11 located between the adjusting plates,
The space between the vibration absorbing plate 14 and the vibration absorbing plate 14 serves as a polyurethane flow path. By injecting the polyurethane 21, the surface level of the polyurethane 21 between the traveling rail 11 and the side wall of the recess 13 and between the derailment prevention rail 12 and the side wall of the recess 13 becomes the same as the upper surface level of the concrete slab 10. After doing so, polyurethane 21 is added between the traveling rail 11 and the derailment prevention rail 12, and the surface level of the polyurethane 21 between the traveling rail 11 and the derailment prevention rail 12 is the same as that of the head of the traveling rail 11. Since it is located at the lower end, each surface level of the polyurethane 21 is properly positioned at a predetermined position, and the recess 13 is formed.
Polyurethane 21 can be filled therein. In addition, the adjustment plate 1
5 and 16 allow the traveling rail 11 and the derailment prevention rail 12
Since the flow of polyurethane passing through the space formed between the bottom surface of each of the above and the vibration absorbing plate 14 is from one direction side, there is no possibility that air will be mixed into the polyurethane and a large void will be generated.

Further, since the polyurethane 21 has a self-leveling property, a horizontal surface can be obtained without using a trowel or the like to level the upper surface. As a result, the work is generally easy. In addition, the obtained rail installation structure includes a traveling rail 11 and a derailment prevention rail 12.
The surface level of the polyurethane layer 21 between and can secure the required depth as a flangeway of the wheel, and between the traveling rail 11 and the side wall of the recess 13 and between the derailment prevention rail 12 and the side wall of the recess 13. Since the surface level of the polyurethane layer 21 between them is set to be substantially the same as the upper surface level of the concrete slab 10, it also protects the side wall of the recess 13.

Further, when the vibration absorbing plate 14 is laid, the adhesive 22 is applied to the bottom surface of the recess 13 and then the vibration absorbing plate 14 is placed and fixedly adhered to the bottom surface of the recess 13. The bottom surface and the vibration absorbing plate 14 are joined together, and in addition to the rail restraint from the side surface of the recess 13 by the polyurethane 21, the rail restraint from the bottom surface of the recess 13 is performed to restrain the rail axial force generated by the temperature contraction of the traveling rail 11. Since the force is increased, stress concentration on the rail branch portion due to thermal contraction of the rail is surely avoided, and damage to these is also prevented.

Further, the pipe 2 is provided between the traveling rail 11 and the derailment prevention rail 12 and the side wall of the recess 13, respectively.
Since 0 is provided, the capacity of the polyurethane 21 to be injected into the recess 13 can be reduced, which is excellent in economic efficiency, and the inside of the pipe 20 can be provided with electric wires and optical fibers necessary for vehicle operation and the like. It can also be used as a storage tube for the like.

Next, as a second embodiment, in the other concave portion 33 (see FIG. 9) in which only the other traveling rail 11 of the concrete slab 10 relating to claims 4 and 17 of the present invention is accommodated. The installation method and installation structure of the rail will be described. Also on the bottom surface of the recess 33,
The vibration absorbing plate 14 made of a synthetic rubber plate or a natural rubber plate is bonded and fixed continuously through the adhesive layer 22 in the laying direction of the traveling rail 11. The vibration absorbing plate 14 may be only a synthetic rubber plate or a natural rubber plate, but in consideration of the train load on the track and the riding comfort, the composition and thickness of the filler such as cork powder are changed to obtain a predetermined elastic coefficient. The one that becomes is selected. The cork particles are preferably contained in the range of 1 to 20% by weight.

Further, a height adjusting plate 15 made of a cork plate is placed on the vibration absorbing plate 14 at intervals. The traveling rail 11 is laid on the plurality of adjusting plates 15. Here, pipes 20 made of vinyl chloride are attached to the outer sides of the traveling rails 11, respectively. Then, the running rail 11 is fixed by injecting and curing the same polyurethane 21 as in the above-described embodiment into the recess 33.

Next, the rail mounting method according to the second embodiment for obtaining the traveling rail mounting structure having the above-described structure will be described with reference to FIGS. 10 to 15. First, as shown in FIG. 10, the concrete slab 10 is
After applying the adhesive 22 to the bottom of the concave portion 33, the vibration absorbing plate 14 is adhesively fixed. As this adhesive 22,
An epoxy resin adhesive to which a curing agent has been added can be preferably used as in the above-described embodiment, and the bottom surface of the recess 33 and the vibration absorbing plate 14 can be reliably bonded. The width of the vibration absorbing plate 14 is smaller than the width of the bottom of the recess 33. This is to expose the bottom of the recess 33 on both sides of the vibration absorbing plate 14 in a state where the vibration absorbing plate 14 is adhesively fixed to the bottom of the recess 33, as described above.
As a result, when the polyurethane 21 is injected and solidified, the polyurethane 21 comes into contact with a part of the bottom of the recess 33 to wrap the vibration absorbing plate 14 and firmly fix it.
The polyurethane 21 itself also contacts the bottom of the recess 33 to increase the strength as a whole.

Next, the height dimension until the upper surface of the vibration absorbing plate 14 and the upper surface 11a of the traveling rail 11 reach a predetermined level is measured at appropriate intervals in the laying direction of the rail 11, and the height dimension shown in FIG. As shown in FIG. 5, the adjusting plate 15 has a thickness dimension corresponding to the height dimension of each measurement point.
Are placed on the vibration absorbing plate 14. The height of the adjusting plate 15 is adjusted by adjusting a plurality of adjusting plates having the same thickness or different thicknesses, for example, 1 mm, 2 mm, 3 mm and 5 m thick.
A plurality of m adjustment plates are prepared, and these adjustment plates are combined and stacked at a predetermined height. As a result, it is not necessary to machine the thickness of the adjusting plate each time, and the positioning of the rail can be adjusted more accurately and easily than in the conventional case. Further, as the adjusting plate, a cork plate which has both vibration absorbing property and sound absorbing property, has elastic properties similar to those of polyurethane, has good compatibility, and is easily workable is preferable.

In parallel with this, the traveling rail 11 is made to have a required length. That is, although the standard length of the rail is generally 25 m, the pipes 20 made of vinyl chloride are provided on both sides of the traveling rail 11 after welding and connecting them to a required length in advance and adjusting the horizontal position. Ring 2
3 and a wire or plastic band (see FIG. 13) 24 wound at appropriate intervals. Then, as shown in FIG. 12, the traveling rail 11 in which these pipes 20 are integrated is placed on the adjusting plate 15.

Then, as shown in FIG.
A wedge member 25 made of cork is struck between the horizontal position adjusting ring 23 mounted on the above and the side wall of the recess 33 to adjust the horizontal position of the traveling rail 11. Then, after the positioning of the traveling rail 11 is completed in this way,
Remove the wire or plastic band 24. Next, FIG.
As shown in FIG. 4, the same primer 26 as in the first embodiment for increasing the adhesive strength with the polyurethane 21 that is injected in a later step is scattered throughout the recess 33.

Next, as shown in FIG. 15, between the side wall 33a (the side wall on the right side in the figure) located outside the rail track of the recess 33 and the traveling rail 11, the polyurethane 2 is provided.
Inject 1. The polyurethane 21 is injected so that the surface level of the polyurethane 21 between the side wall 33a of the recess 33 and the traveling rail 11 becomes the same as the upper surface level of the concrete slab 10. As a result, the injected polyurethane 21 slightly wraps around to the opposite side of the traveling rail 11 through the gap formed by the adjusting plate 15 between the bottom surface of the traveling rail 11 and the vibration absorbing plate 14. In this case, the recess 33 located on the opposite side of the traveling rail 11
The surface level of the polyurethane 21 between the side wall 33b on the inside of the rail track and the traveling rail 11 is
Due to the viscosity of 1 and the progress of curing, it does not rise to the same level as the surface level of the polyurethane 21 on the side wall 33a side of the concave portion 33 located outside the rail track, but stops at a considerably low position.

In this state, polyurethane 21 is added between the side wall 33b of the recess 33 located inside the rail track and the traveling rail 11, and the surface level of the polyurethane 21 is adjusted to the lower end of the head of the traveling rail 11. Be located at. As a result, each surface level of the polyurethane 21 can be properly positioned at a predetermined position, and the polyurethane 21 can be filled in the recess 33. Further, since the polyurethane 21 has self-leveling property, a smooth horizontal surface is naturally formed on the upper surface. To be done.

According to the rail installation structure and installation method having the above-described configuration of the second embodiment, the traveling rail 11 serves as the concrete slab 10 that serves as the base of the track.
Since the entire surface of the web 11b and the lower flange are constrained by the polyurethane 21 in the concave portion 33 formed on the upper surface of the, the holding of the traveling rail 11 is not affected even by long-term use. Further, in the conventional rail mounting structure using sleepers and dog nails, since the rail is supported at intermittent points, relatively large vibration is generated and uneven wear is likely to occur. In the embodiment, since the traveling rail 11 is continuously supported on the surface by the polyurethane 21 filled in the concave portion 33, it is possible to suppress the occurrence of the vibration, and there is no fear that the rail is unevenly worn. .

Further, as a result of supporting the traveling rail 11 in the recess 33 formed on the upper surface of the concrete slab 10, there is no need to use fasteners such as dog nails and screw spikes as in the conventional case. It is possible to greatly reduce the maintenance work of the rails, and various shapes of rails can be used. Further, the vibration absorbing plate 1 is provided on the bottom surface of the recess 33.
Since the vibration absorbing plate 14 is contracted when the train passes and the traveling rail is appropriately sunk, the train ride comfort is improved and vibrations are absorbed. Further, since the lower flange of the traveling rail 11 and the entire surface of the web are constrained by the polyurethane 21, the vibration is synergistically absorbed also from this point, the noise is extremely small, and the service life of the traveling rail is extended. It is possible to ride, and it is comfortable to ride and excellent in safety.

Further, the adjusting plate 15 whose height dimension is adjusted so that the level of the traveling rail 11 becomes a predetermined level,
The vibration absorbing plate 1 is provided along the lower surface laying position of the traveling rail 11.
Since the height of the bottom surface of the concave portion 33 is uneven, the adjustment plate 15 can ensure a high accuracy of the running surface, and the degree of freedom of height adjustment is increased. Moreover,
Since the adjusting plates 15 are placed at predetermined intervals (for example, 1 to 2 m) along the lower surface laying position of the traveling rail, a space is provided between the bottom lower surface of the traveling rail 11 and the vibration absorbing plate 14 by these adjusting plates 15. And the polyurethane 21
To the space by injecting
Is formed, the adjusting plate 15 is fixed to the vibration absorbing plate 14, and the traveling rail 11 itself is also firmly fixed. Therefore, it suffices to simply place the adjusting plate 15 on the vibration absorbing plate 14, the construction is simple, and the bolts, nuts,
Compared to the conventional height adjustment, which was performed while adjusting fasteners such as dog nails and tie plates and sleepers, positioning can be performed accurately and easily in units of 1 mm. . In addition, since polyurethane having self-leveling properties is used when pouring polyurethane into the concave portion, a horizontal surface can be obtained without leveling the upper surface separately, and thus the work is generally easy.

Further, in the second embodiment, first, polyurethane 21 is injected between the side wall 33a of the recess 33 located outside the rail track and the traveling rail 11, and the side wall 33a of the recess 33 and the traveling rail 11 are first injected. Since the surface level of the polyurethane 21 between and is made the same as the upper surface level of the concrete slab 10, the polyurethane 21 is added between the side wall 33b of the recess 33 inside the rail track and the traveling rail 11, so that Polyurethane 21
The surface level of the can be properly positioned in place.

Moreover, the traveling plate 1 is adjusted by the adjusting plate 15.
Since the flow of the polyurethane 21 passing through the space formed between the lower surface of the bottom portion of 1 and the vibration absorbing plate 14 is from one direction side, there is no fear that air will be mixed into the polyurethane 21. In addition, the obtained rail installation structure ensures that the surface level of the polyurethane 21 between the side wall 33b of the recess 33 inside the rail track and the traveling rail 11 ensures the depth required for the flange way of the wheel. it can.

Further, when the vibration absorbing plate 14 is laid, the adhesive 22 is applied to the bottom surface of the recess 33, and then the vibration absorbing plate 14 is placed and fixedly adhered to the bottom surface of the recess 33. The bottom surface and the vibration absorbing plate 14 are joined to each other, and in addition to the rail restraint from the side surface of the recess 33 by the polyurethane 21, the rail restraint from the bottom surface of the recess 33 is performed to restrain the rail axial force generated by the temperature contraction of the traveling rail 11. Since the force is increased, the stress concentration on the rail branch portion due to the thermal contraction of the traveling rail 11 is reliably avoided, and the damage to these is also prevented.

Further, as the polyurethane 21, polyurethane mixed with cork powder is used, and the recess 1
Lay the vibration absorbing plate 14 that serves as a vibration absorbing plate at the bottom of 3,
An adjustment plate 15 made of cork is further provided on the vibration absorbing plate 14.
Since the traveling rail 11 is mounted via the vehicle, it is possible to effectively suppress vibration and noise generated during traveling of the vehicle. Further, since the pipes 20 are respectively arranged between the traveling rail 11 and the side walls of the recess 33, the recess 33
The capacity of the polyurethane 21 to be injected into the pipe 20 can be reduced and the economy is excellent, and the pipe 20
The inside can also be used as a storage tube for electric wires, optical fibers, etc. necessary for vehicle operation and the like.

The fourth to seventh embodiments will be described. Each of the following embodiments relates exclusively to the connection between the traveling rail 11 and the connected traveling rail connected to the traveling rail 11. Regarding the installation method of the traveling rail 11 and the derailment prevention rail 12 itself, Since it is the same as that shown in the second embodiment, the same reference numerals are given below and the description thereof is omitted.

First, the rail installation structure obtained by each of the above-mentioned embodiments will be described. The concrete slab (foundation) 50 is provided with two recesses 13 and 33, and is formed on the inner rail side (see FIG. 17). The traveling rail 11 and the derailment prevention rail 12 are laid in the recess 13 on the side), and the traveling rail 11 is installed in the recess 33 on the outer rail side (the upper side in FIG. 17).

Then, in the recesses 13 and 33, welding recesses 13e and 33e are formed near the connection end 11e of the traveling rail 11, respectively. The welding recesses 13e and 33e are formed wider and deeper to secure a rail welding space. By the way, the welding recesses 13e and 33e may be of any size as long as there is a space where the traveling rails 11 can be welded to each other. For example, the depth is 20 to 30 cm and the width is 35 to 45 cm.
The degree is enough. Then, the welding recesses 13e, 33
In e, the connecting end portions 11e of the traveling rails 11 adjacent to each other in the laying direction are welded to each other, whereby a long rail is achieved. A concrete slab 50 shown in FIG. 18 is provided with a depression at the center thereof, a lower layer of subgrade material such as sand or asphalt is provided in the depression, and a paving stone for paving is provided in the upper layer.

Next, a fourth embodiment of the rail installation method relating to claim 2 of the present invention for obtaining the rail installation structure formed in the inner rail side recess 13 will be described.
First, the recess 13 and the welding recess 13e are formed in the concrete slab 50, and the integrated traveling rail 11 and derailment prevention rail 12 are installed in the same manner as in the first embodiment. At this time, the connection ends 11e of the traveling rail 11 are laid in the recess 13 in a state of protruding from the connection ends of the derailment prevention rail 12,
e is located in the recess 13e for welding. Further, the vibration absorbing plate 14 is adhered and fixed to the bottom surface of the portion of the recess 13 where the traveling rail 11 and the derailment prevention rail 12 are juxtaposed, but it may be laid down near the welding recess 13e in the rail welding space. Absent. It should be noted that the vinyl chloride pipe 20 and the spacer / horizontal position adjusting ring 23 are not attached to both sides of the connection end 11e of the traveling rail 11 at this point because they interfere with rail welding connection.

Next, after the running rail 11 and the derailment prevention rail 12 are positioned by driving the wedge member 25 made of cork in the recessed portion 13, the running rail 11 and the derailment prevention rail 12 are aligned in the recessed portion 13 portion,
That is, as in the first and second embodiments, in the recessed portion 13 except for the portion (near the welding recessed portion 13e) corresponding to the connection end 11e along which the derailment prevention rail 12 of the traveling rail 11 does not extend, in the recessed portion 13. Then, the polyurethane 21 having self-leveling property is injected and cured.

At this time, the injection of the polyurethane 21 is
The range of 1 to 2 m from the end of the traveling rail 11 is not injected in order to avoid the influence of welding heat. On the other hand, since the vibration absorbing plate 14 described above does not contact the traveling rail 11 to be welded and the welding heat is not transmitted, if the spark of welding does not hit, the welding recess 13e of the rail welding space is reached. You can lay it. That is, the above-mentioned connection end portion 1
The extension of the portion corresponding to 1e (in the vicinity of the recess 13e for welding) is determined by the range in which the heat of welding is transmitted to each material and the material is adversely affected.

Further, the ends of the vinyl chloride pipes 20, 20 attached to the outer sides of the traveling rail 11 and the derailment prevention rail 12, respectively, should not be embedded in the polyurethane 21 when the connection is extended, so that the pipe 20 is not embedded. , 20
It is preferable that the partition wall penetrating through is provided at the end of the polyurethane injection portion and the polyurethane 21 is injected. This partition wall is removed after the polyurethane 21 is cured. When the connection is not extended, the ends of the pipes 20, 20 are closed with an adhesive tape or the like, and then the polyurethane 21 is injected and embedded.

Next, the connection end 11e of the traveling rail 11 fixed by the polyurethane 21 and the connection traveling rail fixed by the polyurethane 21 except for the connection end connected to the traveling rail 11 are welded and connected. That is, if the connected traveling rail to be connected to the traveling rail 11 is already fixed in the recess 13 by the polyurethane 21 except for the connecting end portion, the connecting end portions 11e are immediately welded to each other. On the other hand, if the connected traveling rail to be connected to the traveling rail 11 is not yet fixed with the polyurethane 21, after the connected traveling rail is fixed with the polyurethane 21 except for the connection end portion by the same procedure as in the second embodiment. , The connection end portions 11e are welded to each other.

After the welding connection between the connection end portions 11e is completed in this manner, first, the vibration absorbing plate 14 is laid by bonding and fixing it to an unlaid portion near the welding recess 13e.

Then, next, a primer is sprayed in the vicinity of the welding recess 13e, and then polyurethane 21 having a self-leveling property is injected and cured. As a result, the traveling rail 11 is welded in the recess 13 provided in the concrete slab 50, and the installation structure of the traveling rail 11 and the derailment prevention rail 12 which have been made longer rails is completed.

In the fourth embodiment as well, the same operational effects as those of the first and second embodiments described above can be obtained, and further, the connection end 11e of the traveling rail 11 is left and fixed by the polyurethane 21, and this connection is made. Since the end portion 11e and the connection end portion of the adjacent connecting traveling rail, which is also fixed by the polyurethane 21, are welded and connected in the recessed portion 13, the rail position is fixed, so that welding is easy. In addition, the effect that the rail position adjustment after welding is unnecessary is also obtained. Moreover, since the running rail 11 is welded and connected in the recess 13, the seam of the conventional rail can be eliminated, a good ride quality with less vibration can be obtained, and the impact of the conventional rail seam can be prevented. The rail and track structure will be extended.

Before injecting the polyurethane 21 into the recess 13 having the connection end 11e welded and connected, an adhesive is applied to a portion of the bottom surface of the recess 13 having the connection end 11e which is not yet laid on the vibration absorbing plate 14. When the vibration absorbing plate 14 is fixed by adhesion, the structure is similar to the other polyurethane 21 fixing points, the structural peculiarity in the rail welding part can be removed, and the vibration absorbing plate 14 can be passed over the entire length of the traveling rail 11 when the train passes.

Therefore, the wedge member 25 made of cork is adjusted between the horizontal position adjusting ring 23 mounted on the pipe 20 and the side wall of the recess 13 to perform positioning again. To do. Next, the vibration absorbing plate 14 is similarly adhered and laid on the non-laid portion of the vibration absorbing plate 14 on the bottom surface in the vicinity of the welding recess 13e having the connection end 11e.

Let If the connected traveling rail welded to the traveling rail 11 is not fixed by the polyurethane 21, polyurethane having self-leveling property is injected not only at the connecting end of the connected traveling rail but also over its entire length. Then, it is recommended to cure.

When the other connection end (not shown) of the traveling rail 11 is unwelded, the primer spraying and the polyurethane injection are performed on the recessed portion 13 excluding the portion corresponding to the unwelded connection end. To do. In this case, the injection of polyurethane 21 is 1-2 from the end of the traveling rail 11.
The range of m should not be injected in order to avoid the influence of welding heat due to rail connection welding in the subsequent process. On the other hand, the vibration absorbing plate 14 described above is used for the traveling rail 1 to be welded.
Since the welding heat is not transmitted because it is not in contact with No. 1, the welding can be installed up to the vicinity of the welding recess 13e in the rail welding space unless the welding spark strikes.

Further, the ends of the vinyl chloride pipes 20 and 20 attached to the outer sides of the traveling rail 11 and the derailment prevention rail 12 near the unwelded connection end are polyurethane 21 when the connection is extended. In order not to be embedded in the
