Description

  The present invention relates to a sleeper tree connection structure that connects a plurality of sleeper trees, and a method for manufacturing the sleeper tree connection structure.

The sleepers generally used have a long shape in which the length in the longitudinal direction is longer than that between the gauges, the longitudinal direction is arranged substantially perpendicular to the rail direction, and each sleeper is fastened to two rails.
And when a train passes on a rail, the same sleeper receives the force which receives from the wheel of both sides via each rail.

  At the rail joints and branching parts, the bending rigidity of the rails is lower than at other parts. Therefore, in the case of a ballast roadbed or the like, ballast consolidation tends to proceed due to the train load. As consolidation progresses, vertical movement (so-called tilting phenomenon) tends to occur when the train passes, and when such vertical movement occurs, the ride comfort deteriorates and there is a problem of track management.

  Therefore, according to the method disclosed in Patent Document 1 and the like, the sleepers are connected to each other so that the load of the train passing over the sleepers is distributed to a plurality of sleepers to take measures against the above problem. .

In the method of Patent Document 1, at least a pair of connecting members each having a flat plate portion are used, and a plurality of sleepers arranged side by side are arranged so as to be sandwiched from above and below by the plate portions, and the plate portion and the sleepers are arranged. It is fixed through a bolt inserted through the through-hole and a nut screwed into the bolt.

  The sleeper tree connection structure 1 according to the first embodiment of the present invention is shown in FIGS. 1 to 3, and a sleeper tree 81 arranged on the lower side of the rail 80 is connected using a sleeper tree connection member 10. It is what. The sleeper tree connecting members 10 are arranged at both ends of the sleeper tree 81 in the longitudinal direction, and the sleeper trees 81 are connected at two locations.

  In this embodiment, among the sleepers 81 arranged on the lower side of the rail 80, there are two sleepers 81 to be connected, and these sleepers 81 are arranged so as to sandwich the joint portion 82 of the rail 80. It is what.

  The material of the sleeper tree 81 is not limited, but it is possible to use a material obtained by laminating a foam obtained by reinforcing a hard urethane resin with long glass fibers (product name: Eslon Neo Lumber FFU, manufactured by Sekisui Chemical Co., Ltd.).

  The sleeper connecting member 10 is an L-shaped steel having a long L shape. In the sleeper connecting structure 1, two sleepers 81 are used at each of two ends of the sleeper 81, and a total of four are used. Yes. The two sleeper link members 10 are arranged one above the other, and a sleeper link member 10a located on the upper side and a sleeper link member 10b located on the lower side are provided.

The sleeper linking member 10 a located on the upper side has a horizontal plate 16 and a vertical plate 17, the horizontal plate 16 is located above the upper surface 30 of the sleeper 81, and the vertical plate 17 is located outside the mouth end 31 of the sleeper 81. positioned. Moreover, the sleeper link member 10b located on the lower side has a horizontal plate 18 and a vertical part 19, and the horizontal plate 18 is located below the lower surface 32 of the sleeper 81, and the vertical plate 19 is a front end of the sleeper 81. 31 is located outside. The vertical plate 17 and the vertical plate 19 can cover most of the front end 31 of the sleeper 81 to be connected.
The sleeper 81 is sandwiched between the horizontal plate 16 of the sleeper connecting member 10a located on the upper side and the horizontal plate 18 of the sleeper connecting member 10b located on the lower side.

The horizontal plates 16 and 18 and the vertical plates 17 and 19 are long flat plate shapes. The lengths of the horizontal plates 16 and 18 and the vertical plates 17 and 19 are longer than the interval between the sleepers 81 to be connected, and are the same length therebetween. For this reason, the sleeper connecting member 10 is provided with a protruding region 24 that is an outer portion of the two sleeper trees 81.
The horizontal plates 16 and 18 are formed with through holes 16a and 18a. The positions of the through holes 16a and 18a are adjusted to the positions of the through holes 81a provided in the sleeper 81, the through holes 16a, 18a and 81a can be communicated, and bolts 12 which will be described later can be inserted.

  The horizontal plates 16, 18 and the vertical plates 17, 19 have the same width and are slightly shorter than half the height of the sleeper 81. Therefore, when the sleeper coupling members 10a and 10b are arranged one above the other, the vertical plates 17 and 19 do not interfere with each other.

  In the sleeper tree connection structure 1, two vertical restriction members 11 are used at one location, and the position corresponds to the position of the sleeper tree 81. Further, the width of the vertical regulating member 11 (the length in the direction of the rail 80) is substantially equal to the width of the sleeper 81. Therefore, the front end 31 of the sleeper 81 exposed from the gap between the vertical plate 17 and the vertical plate 19 can be reliably covered, and the front end 31 of the sleeper 81 can be made difficult to contact with the ballast.

The vertical regulating member 11 is a groove steel having a U-shaped cross section. As shown in FIG. 2, the upper horizontal plate (upper portion) 20, the vertical plate (interval maintaining portion) 21, and the lower horizontal plate. (Lower part) 22 is provided. The upper horizontal plate 20 and the lower horizontal plate 22 are rectangular plates, and these shapes are the same. The shape of the vertical plate 21 is a rectangular plate shape.
Even when a force is applied between the upper horizontal plate 20 and the lower horizontal plate 22 of the vertical regulating member 11 in a direction away from each other, the vertical plate 21 causes the upper horizontal plate 20 and the lower horizontal plate 22 to be separated from each other. The distance can be maintained.

As shown in FIG. 3, the vertical regulation member 11 is installed in a state in which the sleeper connection member 10 a, the sleeper 81, and the sleeper connection member 10 b are positioned between the upper horizontal plate 20 and the lower horizontal plate 22. The vertical plate 21 is positioned so as to be positioned outside the sleeper coupling members 10a and 10b. The upper horizontal plate 20 is disposed above the horizontal plate 16 of the sleeper connecting member 10a, the lower horizontal plate 22 is disposed below the horizontal plate 18 of the sleeper connecting member 10b, and the vertical plate 21 is the sleeper connecting member 10a. It is located outside the vertical plates 17 and 19 of 10b. Further, the horizontal plate 16 of the sleeper connecting member 10a is located between the upper horizontal plate 20 and the sleeper 81, and the horizontal plate 18 of the sleeper connecting member 10b is interposed between the lower horizontal plate 22 and the sleeper 81. positioned.
Moreover, in the state in which the vertical regulating member 11 is installed, the plate surfaces of the upper horizontal plate 20 and the lower horizontal plate 22 are horizontal surfaces, and the plate surface of the vertical plate 21 is a vertical surface.

The sleeper tree connection structure 1 is formed by arranging the sleeper tree connection member 10a and the sleeper tree connection member 10b at the end of the sleeper tree 81, and then installing the two upper and lower regulating members 11. Then, the position of the through hole 81a of the sleeper 81, the through holes 16a and 18a of the sleeper coupling members 10a and 10b, and the through holes 20a and 22a of the upper and lower restricting member 11 are aligned, and the bolt 12 is inserted. The bolt 12 is screwed into the nut 15 fixed to the lower side of the through hole 22 a of the side horizontal plate 22. In this way, the sleeper coupling members 10a and 10b and the vertical regulating member 11 are prevented from coming off.
In addition, although the sleeper 81 formed beforehand may be used for the through-hole 81a of the sleeper 81, you may perforate when forming the sleeper connection structure 1.

  The operation of connecting the sleeper trees 81 as in the sleeper connection structure 1 can be performed by removing as many ballasts (not shown) as necessary while being arranged below the rails 80. However, the sleeper trees 81 are removed from the rails 80. The sleeper tree 81 can be connected in the state, and the sleeper tree 81 can be connected to the lower side of the rail 80.

And as shown in FIG. 1, the both ends of the two pillows 81 are connected, and the sleeper connection structure 1 is completed. Since the sleeper tree connection structure 1 is provided at the joint portion 82 of the rail 80, consolidation of the ballast can be reduced by the train load, and the occurrence of the so-called tilt phenomenon can be reduced.
Further, even when a force is applied in the direction in which the sleeper coupling members 10a and 10b are separated in the vertical direction, the vertical movement of the two horizontal plates 16 and 18 is regulated by the vertical regulation member 11 to By maintaining the distance between the connecting members 10a and 10b, it is possible to prevent a large force from being applied to the bolt 12, and to prevent the bolt 12 and the nut 15 from loosening.

  Furthermore, even if the bolt 12 is loosened, the sleeper link members 10a and 10b are not detached, and the use can be continued. That is, even if the bolt 12 is inserted from above and becomes loose, the sleeper coupling members 10a and 10b, the vertical regulating member 11 and the through holes 16a, 18a, 20a, 22a and 81a of the sleeper 81 are provided. Since the inserted state is maintained, the sleeper coupling members 10 a and 10 b and the vertical regulation member 11 do not leave the sleeper 81. And the sleeper coupling members 10a and 10b are pressed from the up and down direction by the up and down regulating member 11 and thus cannot be removed.

In the sleeper connection structure 1, the sleeper tree connection members 10 a and 10 b are prevented from being separated in the vertical direction by the vertical restriction member 11, so that the upper horizontal plate 20 and the lower horizontal plate 22 of the vertical restriction member 11, It is desirable that there is no gap between the sleeper-plate connecting members 10a and 10b and the horizontal plates 16 and 18 so that they are more closely attached.
Therefore, the sleeper link structure 1a according to the second embodiment in which the elastic member 33 is disposed between the horizontal plates 16 and 18 of the sleeper link members 10a and 10b and the sleeper tree 81 can be employed. The sleeper tree connection structure 1a is shown in FIG. 7, and is formed by the method shown in FIGS.

  In the sleeper tree connection structure 1a, the elastic material 33 is attached to the upper surface 30 and the lower surface 32 of the sleeper tree 81 (FIG. 4). The elastic material 33 is specifically a rubber sheet, but other materials can be used as long as the material is deformable by compression. The thickness of the elastic member 33 is desirably 3 mm to 6 mm. The elastic member 33 has a through hole 33a, and the bolt 12 can be inserted into the through hole 33a.

Next, the sleeper coupling members 10a and 10b are arranged outside the elastic member 33 so that the horizontal plates 16 and 18 are located. Further, as shown in FIG. 5, the horizontal plates 16 and 18 are compressed by the compression tool 34 so as to be close to each other. As the compression tool 34, a giant clam vise can be used.
The position compressed by the compression tool 34 is a position that avoids the position where the vertical regulating member 11 is disposed. In this embodiment, the protruding areas 24 on both sides, which are different from the positions corresponding to the sleepers 81, and the sleepers The three intermediate regions 25 are located at positions corresponding to 81.

In this state, the upper / lower regulating member 11 is arranged and fixed by the bolt 12. Since compression is performed by the compression tool 34, the elastic member 33 is compressed and deformed, so that the vertical regulating member 11 can be easily inserted. The removal of the compression tool 34 is performed after the upper / lower regulating member 11 is disposed.
In this way, the sleeper link connection structure 1a is completed.

  In the sleeper connection structure 1a, the elastic member 33 is disposed between the sleeper tree 81 and the horizontal plates 16 and 18 of the sleeper connection members 10a and 10b. Therefore, even when the height of the sleeper tree 81 is slightly changed, It becomes possible to make the vertical regulation member 11 and the sleeper coupling members 10a and 10b closely contact each other.

In the sleeper connection structure 1, 1 a described above, the position where the vertical regulating member 11 is installed is a position corresponding to the position of the sleeper 81, but may be provided at other positions.
For example, as shown in FIG. 8 and FIG. 9, the length of the vertical regulating member 11 (length in the rail 80 direction) is long as in the sleeper tree connection structure 2 in the third embodiment of the present invention. The number of the upper and lower restricting members 11 used for the above can be one. In the sleeper connection structure 2, the length of the vertical restriction member 11 is substantially equal to the outer width of the sleeper 81 to be connected.
In addition, when the elastic member 30 is disposed between the sleeper tree 81 and the sleeper coupling members 10a and 10b, the positions to be compressed by the compression tool 34 are disposed at two locations on the protruding regions 24 on both sides.

Further, as in the sleeper connection structure 3 in the fourth embodiment of the present invention shown in FIGS. 10, 11, and 12, the upper and lower restricting members 11 are used, and the protruding area 24 on both sides and the intermediate area 25 are used. Can be placed in three places. In this case, to prevent the vertical regulating member 11 from coming off, another bolt 37 is used instead of the bolt 12 used for fixing the sleeper 81.
That is, as shown in FIGS. 11 and 12, the sleeper tree coupling members 10 a and 10 b are provided with through holes 38 at positions corresponding to the through holes 20 a and 22 a of the vertical regulating member 11, and the vicinity of the through holes 38. A nut 39 is fixed to the nut. Then, the bolt 37 is inserted into the through holes 20 a and 22 a and the through hole 38 and screwed with the nut 39 to prevent the vertical regulating member 11 from coming off. Moreover, the sleeper connecting members 10 a and 10 b and the sleeper 81 are fixed by bolts 12 and nuts 15.

Therefore, the operation of connecting the sleeper tree connecting members 10a and 10b using the bolts 12 and the operation of preventing the vertical regulating member 11 from being detached using the bolts 37 can be performed separately.
When the elastic member 33 is disposed between the sleeper tree 81 and the sleeper coupling members 10 a and 10 b, the compression tool 34 is compressed at two positions corresponding to the sleeper tree 81.

  Moreover, when installing without using the compression tool 34, the sleeper connecting member 10 as a whole is controlled by the vertical regulating member 11 as in the sleeper connecting structure 5 in the fifth embodiment shown in FIGS. It may be covered.

The vertical regulation member 11 of the sleeper connection structure 1, 1 a, 2, 3 described above is arranged so that the vertical plate 21 is located outside the vertical plates 17, 19 of the sleeper connection members 10 a, 10 b. Can be arranged to be inside the vertical plates 17 and 19 with the opposite side facing the opposite side. In addition, the shape of the upper / lower regulating member 11 of the sleeper tree coupling structures 1, 1 a, 2, and 3 has a U-shaped cross section, but other shapes may be used. It is also good.
Further, the number of sleepers 81 to be connected is not limited to two, and may be three or more.
