2. Description of the Related Art Railroad crossings where a road crosses a track in a plane are provided with railroad crossing pavement so as to eliminate the level difference of the rails and to make the rails substantially level with the road surface. Stone, concrete, asphalt, etc. are generally used as the pavement material for railroad crossings. For such railroad crossings, track maintenance is regularly performed in order to ensure the safety of railway and road traffic. Since track maintenance is based on mechanical repair by Multai (MTT) work or manual repair by tampering, the level crossing must be removed and restored every time track maintenance is performed.

However, in the concrete block pavement and asphalt pavement which are widely used at present, since the pavement material is damaged, an extra replacement cost is required every time maintenance work is performed, and the members are heavy. Therefore, a lot of labor is required. Moreover, due to the increase in road traffic in recent years, it is not allowed to block roads for a long time, and the level crossing pavement must be removed and restored within a short time.

In view of the above situation, the level crossing pavement using the level crossing floorboard that can be easily removed and restored in a short period of time is a periodical publication "New Track" (issued by the railway operating company) in 1995. It is published on pages 19 to 21 of the October issue.

The crossing pavement using the crossing floor plate is shown in FIG.
Et al. Are composed of members as shown in FIG . That is,
Two edge cutting members 101 having the same length as the road width are arranged at the positions of both ends of the sleeper 1. A total of three low-position determining members 102 as shown in FIGS. 9 and 10 are fixed to the sleeper 1 inside the track center and the edge cutting member 101 so that the sleeper 1 inside the railroad crossing does not move. Between the position determining member 102 fixed at the center of the track and the rail 2, a side track pavement member 103 having a step shape is installed. Between the outside of the rail 2 and the position determining member 102, an outside-gauge pavement member 104 having a stepped side surface is installed.

On the sleeper 1 on the bottom side of the inside-gauge pavement member 103 and outside-gauge pavement member 104 (hereinafter referred to as "paving member"), a large notch 1 is formed as shown in FIG.
03a and 104a are formed so as not to obstruct the tie plate 105 for fastening the rail 2 to the sleeper 1. Notches are formed on the bottom sides of the pavement members 103 and 104 between the sleepers 1 so as not to interfere with the bottom portions 2a of the rails 2 as shown in FIG . Pavement member 103,
A mixture of sand and resin is sprayed on the surface of 104 to prevent slippage. And three position determining members 1
02, and a pressing member 106 is detachably fixed on the step between the paving members 103 and 104.

Such a level crossing pavement is laid by the steps shown in FIGS. 11 to 13 . That is, first drawing
As shown in FIG. 11 , with the rail 2 fastened to the sleeper tree 1 laid on the roadbed by the tie plate 105, the edging members 101 are arranged at the positions of both ends of the sleeper tree 1. Then, the position determining member 102 is fixed to the center of the track and the inside of the edge cutting member 101. Next, as shown in FIG. 12 , the pavement members 103 and 104 are installed on the sleeper 1. The pavement members 103 and 104 are not fixed, but the rail 2
A steel hook (not shown) is hooked on the bottom portion 2a of the above to take measures to prevent floating. Finally, as shown in FIG. 9 , the pressing member 106 is sewn and fixed on the pressing member 106 and the pavement members 103 and 104 with a fastening member such as a screw nail to complete the level crossing pavement.

When carrying out track maintenance, the screw nail is loosened with an impact wrench or the like, and the pressing member 106 and the pavement members 103 and 104 are removed from the railroad crossing. Since each member is divided, it can be removed by a small number of people in a short time. And Marutai (MT
T) Machine maintenance by work or manual work by tamper. At this time, since the sleeper 1 is fixed by the position determining member 102, the sleeper 1 is not displaced. When track maintenance is completed, paving member 1
When 03 and 104 are returned to the original position and the pressing member 106 is fastened by the fastening member, the restoration of the railroad crossing is completed.

A rail attachment member is a track component similar to a railroad crossing floor plate. The rail attachment member is a long member attached to the side portion of the rail so as to prevent the asphalt from collapsing toward the rail side when paving the inside of the railroad crossing. The conventional rail attachment member 50 is
As shown in FIG. 14, the cross section has an “inverted L” shape, and the bottom portion on the rail 2 side is notched so as not to interfere with the bottom portion 2 a of the rail 2.

[0010]

The above-mentioned level crossing pavement is provided in order to facilitate track maintenance.
Since 3, 104 are only placed on the sleeper 1, the paving member 103 is in a state of slightly sliding on the sleeper 1. Therefore, when the vehicle passes over the railroad crossing, the position adjacent to the portion where the wheels of the vehicle pass is the pavement member 1
03 and 104 are displaced on the sleeper tree 1, and the concentrated load is applied only to the sleeper tree 1 at the portion where the wheels pass.

If the pavement members 103, 104 and the sleeper 1 are integrally fixed, the pavement members 103, 104
Since the vehicle 104 does not slide on the sleeper 1, when the vehicle passes over the railroad crossing, the pavement member 10 at the portion where the wheels pass through
The distributed load is also applied to the sleeper 1 on 3, 104 and the sleeper 1 in the portion adjacent to the portion where the wheel passes. Therefore, in this case, the pavement members 103 and 104, through which the vehicle has passed, are supported by the plurality of sleepers 1, and therefore do not sink much.

However, if the pavement members 103 and 104 are simply placed on the sleeper tree 1, the pavement member 103, 104 is placed at the portion of the sleeper tree 1 where a concentrated load is applied by the passage of the vehicle. 104 is extremely subsidence. Then, since the pavement members 103 and 104 are fatigued, there is a problem that the conventional level crossing pavement cannot withstand long-term use.

Although the number of parts in the level crossing pavement disclosed in the periodical "Shinkansen" has been reduced, there is a demand to make the track maintenance even easier by further reducing the number of parts. is there.

In addition, there is another demand in the art to improve the durability of the conventional crossing floor plate, particularly the pavement member 103. That is, the paving member 103 of the prior art has a shape in which the rail side of the bottom surface is cut out in order to avoid interference with the bottom portion 2a of the rail 2. Therefore, the portion has a cantilever structure and is weak against a load from above. As a result, the pavement member 103 in the vicinity of the rail 2 may be cracked and fallen off due to the load of an automobile or the like passing through the railroad crossing. In addition, when a vehicle passes over the cutout portion of the pavement member 103, the pavement member 103 often bends or the entire pavement member 103 tilts even if the portion does not break. Therefore, there is a problem that the pavement member 103 is fatigue-damaged or the bottom surface of the pavement member 103 is unevenly worn and rattles due to long-term use.

Also in the above-mentioned rail attachment member 50 ,
There is a similar problem, and since the bottom portion on the rail 2 side is notched so as not to interfere with the bottom portion 2a of the rail 2, the portion near the rail 2 may be chipped. In addition, the portion near the rail 2 may be fatigue-damaged or the bottom surface may be unevenly worn and rattled.

[0016] Therefore, the present invention aims to stabilize the track when a vehicle passes over the crossing, and at the time of track maintenance, the track can be easily removed and restored in a short time and has high durability. The purpose is to provide a floorboard.

[0017]

[Means for Solving the Problems] The first means for solving the above-mentioned problems is to install a main body on a plurality of sleepers in a railroad crossing at approximately the same height as the road surface, and to place the bottom surface of the main body on the sleepers. In a railroad crossing floorboard with a cutout portion for accommodating the rail fastening device, the main body is molded from glass long fibers and hard foam resin, and the direction of the glass long fibers in the middle layer of the main body is set in the width direction (length of sleeper tree). Direction) , the glass filaments in the upper and lower layers are arranged in the length direction (width direction of the road) so that the directions of the three glass filaments are alternately orthogonal to each other, and the main body and the sleeper are arranged. It is a railroad crossing floorboard characterized by being fixed by a fastening member.

According to the above-mentioned first means, the railroad crossing base plate and the sleeper are integrated by fixing the main body and the sleeper by the fastening member. Therefore, when the vehicle passes over the railroad crossing floor plate, the concentrated load is not applied to the portion directly below the wheels of the vehicle but is supported by a plurality of sleepers, so that the railroad crossing floor plate does not extremely sink.
Since the main body is molded from long glass fiber and hard foamed resin, a fastening member such as a screw nail can be screwed into the main body, which facilitates work at a laying site. Moreover, since the main body does not absorb water or decay, the life of the product can be extended. The direction of the long glass fibers in the middle layer of the main body is the width direction (the length direction of the sleeper) , and the direction of the long glass fibers in the upper and lower layers is the length direction (road width).
Membered arranged direction), by the direction of the long glass fibers of 3 layers are perpendicular to each other alternately, can damage such as cracks in the notch by glass fibers of the intermediate layer is so unlikely to occur, the upper and lower The layer of glass fibers can increase the rigidity of the entire roadbed.

A second means for solving the above-mentioned problems is, in the railroad crossing floor plate according to the above-mentioned first means, the bottom of the main body, and the notch between the sleepers is brought into contact with the bottom of the rail. A railroad crossing floor plate having a supporting member fixed thereto.

According to second means, by which is fixed a bearing member in the notch of the body, even if a load is applied between sleepers, because the body is in contact with the bottom of the rail, the body Does not bend. Moreover, since the support member can be formed separately from the main body, the main body can be easily processed, and the support member can be cut at the laying site to facilitate site alignment.

A third means for solving the above-mentioned problems is the railroad crossing floorboard according to the above-mentioned first means or second means, wherein a floorboard is fixed to the surface of the main body. It is a roadbed.

According to third means of said, decking by not only the main body is protected, it is possible to prevent a vehicle slip through the railroad crossing.

A fourth means for solving the above-mentioned problems is, in the railroad crossing floor plate according to any one of the first to third means, a portion of the back surface of the main body which is in contact with the sleeper is made of an abrasion resistant material. It is a railroad crossing floorboard that is characterized.

According to fourth means described above, does not occur backside wear of crossing paths floorboards, durability is greatly improved.

A fifth means for solving the above-mentioned problems is the railroad crossing floorboard according to any one of the first to fourth means, wherein the length of the main body is the width of the width of the railroad crossing. It is a railroad crossing floorboard characterized by that.

According to the fifth means mentioned above, by which the length of the body and the width of the width of the railroad crossing, the body is elongated.
Therefore, when a vehicle having a railroad crossing passes over the main railroad crossing floor plate, a distributed load is applied to a large number of sleepers, and the railroad crossing floor plate is further prevented from sinking.

As described above, the railroad crossing plate according to the present invention is
The main body 10 and the floor plate 20 are fastened by the fastening member 30 to the sleeper 1
It can be constructed from only a few parts that are fixed to. Next, a method of laying the railroad crossing floorboard will be described.

Firstly advance, the soleplate 20 is fixed by screws onto the main body 10 which is fixed a bearing member 12 in the notch 11, the small holes 24 of the head portion of the screw cap or by filling a curable resin Close up and form a unit of railroad crossing floorboards. Then, a large number of units of the railroad crossing floorboard are installed on the sleeper 1 to which the rail 2 is attached by the fastening device 3. At this time, it installs so that the communication hole 25 of a railroad crossing floorboard may be located on the sleeper tree 1. Also, the main body 10
The support member 12 fixed to the notch 11 is in contact with the bottom portion 2a of the rail 2 between the sleepers 1. At the laying site, if the support member 12 also comes into contact with the fastening device 3 of the rail 2, a part of the support member 12 is cut. Then, with the unit of the railroad crossing floorboard installed on the sleeper 1 in the desired state, the fastening member 30 is inserted into the communication hole 25 of the railroad crossing floorboard, and the tip end of the fastening member 30 is tightened into the sleeper 1. . Finally, the cap 26 is attached to the head of the fastening member 30.
The railroad crossing pavement is completed by fitting in and closing the recess of the communication hole 25.

In this railroad crossing pavement, the fastening member 30 makes the railroad crossing floorboard and the sleeper 1 integral with each other. The railroad crossing floorboard unit is placed on a few sleepers 1 and integrated with the sleepers 1, so that when a vehicle passes through the crossing pavement, a concentrated load is applied on one sleeper 1. Instead, the distributed load is applied to the plurality of sleepers 1. Moreover, since the supporting member 12 fixed to the notch 11 of the main body 10 abuts on the bottom 2a of the rail 2, the railroad crossing floor plate between the sleepers 1 does not bend even if a distributed load is applied.

Further , as shown in FIG. 6, the shape of the main body 10 may be one or two elongated shapes in the width direction of the road. In this case, the load of the vehicle or the like should be further distributed load. You can That is, when a vehicle passes over the level crossing pavement, the level crossing floorboard and the sleeper 1 slightly sink together. Therefore, when the vehicle passes over the crossing pavement, fatigue of the crossing floor plate is unlikely to occur.

In order to prevent the roadbed sinking of the lower surface of the sleeper 1 due to concentrated loads of the main body 10 when passing through the train and passing the vehicle, whichever the shape of the main body 10 is as shown in FIG. 1 and FIG. 2 or FIG. Most preferably, the entire roadbed is a rigid body. Therefore, the main body 10 is molded in consideration of the direction of the FFU glass long fibers .

The main body 10 is formed by laminating so that the directions of long glass fibers are alternately orthogonal to each other. As shown in FIG. 7, the direction of the glass long fibers of the middle layer of the main body 10 is the width direction (the length direction of the sleeper 1), and the direction of the glass long fibers of the upper and lower layers is the length direction (the width direction of the road). ), So that the directions of the three long glass fibers are alternately orthogonal to each other. The glass fibers of the intermediate layer can prevent breakage such as cracks from occurring in the cutout portion 11, and the glass fibers of the upper and lower layers can increase the rigidity of the entire roadbed.

[0042] by addition Marutai (MTT) work, when the machine repair, remove the cap 26 which closes the recess of the communication hole 25 is withdrawn a fastening member 30. Then, when hook bolts are attached to the main body 10 and lifted, the railroad crossing floor plate can be discharged to the outside of the railroad crossing. After the railroad crossing floorboard is discharged, the roadbed can be compacted by mechanical repair. When the mechanical repair is finished, the railroad crossing floorboard is placed on the sleeper tree 1 again, fixed to the sleeper tree 1 by the fastening member 30, and the cap 26 is put in the recess of the communication hole 25, whereby the original crossing pavement can be restored. .

The present invention is not limited to the above-mentioned embodiment, and the design can be changed within the scope of the present invention. For example, the fastening member may be a screw bolt instead of the screw nail. Further, the sleepers may be synthetic sleepers or tree sleepers.
