Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laying a connection sleeper tree, which is preferably used for a seam of rails or a branch portion of rails.

[0002]

2. Description of the Related Art Conventionally, sleepers are made of wood or PC.
Those made by (Prestressed Concrete) are generally used. Although wooden sleepers are lightweight and resistant to vibration, they have the drawbacks of short service life, low trackbed resistance, and depletion of wood resources.
On the other hand, the PC sleepers are strong against bending load and have a long service life, but have a heavy weight, and there is a tendency that the laying work becomes large-scale. Moreover, the sleepers made of PC are weak in vibration reducing property and are not suitable for the branch portions of the rails.

Therefore, in recent years, as an alternative to these sleepers, synthetic sleepers made of synthetic wood made of a fiber-reinforced hard resin foam have been used. This synthetic sleeper is not only light and strong, but also durable. Also, because it is strong against vibration, it is preferably used for rail joints and branch points.

Sleepers are laid in a roadbed piled on a roadbed. Depending on the conditions of the route, the ballast is a ballast floor,
Concrete roadbed and slab roadbed are selected. Ballast beds are more widely used than concrete or slab beds because of the cheap construction costs and the relative ease with which track deviations can be corrected. Ballast spreads the load applied from the train to the sleeper through the rail widely and transmits it to the roadbed to prevent lateral movement of the vehicle and movement of the sleeper due to expansion and contraction of the rail, and absorb the vibration energy accompanying the running of the vehicle. Yes, gravel and crushed stone are used.

By the way, the sleepers laid on the joints and branches of the rails have large vibrations as the train passes, and the load on the trains causes the lower surface of the sleepers to be consolidated, causing track subsidence, and sometimes the tracks move up and down. A so-called "flapping phenomenon" such as lateral deviation is likely to occur. As described above, the synthetic sleepers are often used at the joints and branching portions of the rails, but since the synthetic sleepers are light in weight, the “flapping phenomenon” is particularly likely to occur.

Therefore, in order to prevent the occurrence of the "flapping phenomenon", a linked sleeper is used. The connected sleeper has a connecting member bridged between a plurality of sleepers, and has a large overall shape, and has a large contact area with the ballast or a large ground contact area. As a result, the connected sleeper has a high resistance to vertical movement, and it is possible to effectively prevent the occurrence of the “flapping phenomenon”.

[0007]

However, as described above, since the connected sleeper has a large overall shape and is heavy,
Transporting to the laying site and laying work were large-scale. In addition, when replacing unconnected existing sleepers with connected sleepers at rail joints, branching parts, etc., laying work was performed by removing multiple existing sleepers from the rails and attaching the connected sleepers to the rails. . Therefore, the sleepers were not laid under the rails for a long time during the laying work, and the replacement work could not be performed during the daytime when trains frequently pass. For this reason,
The work of laying the connected sleepers has to be done at night, which is inefficient and costly, so improvements have been desired.

The present invention is proposed in view of the above circumstances, and an object of the present invention is to provide a method of laying a connected sleeper that allows a train to pass while efficiently performing a laying work.

[0009]

The present invention according to claim 1, which is proposed to achieve the above object, is a method for laying two or more sleepers connected to each other, wherein the sleepers are pre-connected to each sleeper. The members are fixed to each other, and each sleeper is laid under the rail, and then the sleepers are connected to each other by connecting the respective sleeper connecting members or the connecting member and the sleeper abutting the connecting member. .

According to the present invention, since the ties are not connected in advance, the individual ties are lightweight, easy to transport to the laying site, and easy to lay.
Further, instead of fixing the connecting member to the sleeper at the installation site, the connecting member is firmly fixed to the sleeper in advance. Due to this, even immediately after installation, due to the large resistance force generated between the ballast and the connecting member against vertical movement,
The vertical vibration of the sleeper can be effectively suppressed.

As a structure for connecting the sleepers with the connecting member, for example, a structure for connecting the sleepers by connecting the connecting members fixed to each sleeper can be adopted. It is also possible to adopt a configuration in which the sleepers are connected to each other by connecting the connecting member fixed to each sleeper to the other sleeper.

In the structure in which the connecting members are connected to each other and the sleepers are connected, it is desirable to employ a connecting structure that secures the connecting strength (bending and shearing strength) of the connecting members in the longitudinal direction. As a result, it is possible to immediately secure the bending and shearing strength similar to that of the connected sleepers connected in advance at the time of laying. Examples of the connection structure that secures the bending and shearing strength of the connecting member include an integral connecting structure that secures the cross-sectional shape of the connecting member and drives the connecting pin in a direction orthogonal to the longitudinal direction.

According to a second aspect of the present invention, there is provided a method for laying two or more sleepers connected to each other, wherein a connecting member is bridged and connected between the sleepers at a laying site, and then the sleepers are connected. The sleepers are laid under the rails.

According to the present invention, the sleeper and the connecting member are connected and fixed at the laying site. Therefore, it is possible to easily carry out the work of transporting the members to the laying site, as compared with the case of transporting the heavy-weight coupled sleepers that are previously coupled. Further, when connecting the connecting member and the sleeper, the bending and shearing strength at the time of laying can be immediately secured by adopting a connecting pin or the like, as in the case of connecting the connecting members described above. Further, in order to further improve the connection strength against vibration in the vertical direction at the time of laying, for example, a connecting member is arranged so as to be bridged to a plurality of sleepers and sandwiched from above and below, and between the sleepers, an upper and lower connecting member A structure in which a spacer is arranged between the sleepers and the upper and lower connecting members is integrally connected and fixed by connecting pins, and the spacer and the upper and lower connecting members are integrally connected and fixed using bolts and nuts. Can be taken. Thereby, the loosening of the connecting pin immediately after the connection caused by the vertical vibration can be suppressed by fastening the bolt and the nut.

The present invention according to claim 3 is a method of laying a connected sleeper tree, in which two or more existing sleepers adjacent to each other are replaced with two or more new sleepers connected to each other.
Fix the connecting member to each new sleeper in advance, remove one of the existing sleepers from the rail, and then lay the new sleeper under the rail.Repeat the existing sleepers by repeating the process. The new sleepers are connected to each other by connecting the connecting members of the new sleepers or the connecting members and the new sleepers that are in contact with the connecting members.

According to the present invention, the existing sleepers are replaced one by one with the new sleepers, all the existing sleepers are replaced with the new sleepers, and then the connecting members are connected and fixed. Therefore, the time during which the sleeper is not laid under the rail during the laying work can be shortened. As a result, the laying work can be promoted during the passage of the train, and the laying work in the daytime can also be performed. Further, as in the present invention according to claim 1, since the sleepers are not connected in advance,
The individual members are lightweight and easy to transport to the installation site, and the installation work is easy. Also, as mentioned above,
Instead of fixing the connecting member to the sleeper at the laying site,
The connecting member is previously firmly fixed to the sleeper. As a result, even immediately after installation, a large resistance force generated between the ballast and the connecting member against vertical movement can effectively suppress vertical vibration of the sleeper. Further, when adopting a configuration of connecting the sleepers by connecting the connecting members, by performing the connection of the connecting members with the connection pin described above, bending and shearing strength similar to the previously connected connected sleepers. It can be secured immediately after installation.

During the laying, if a new sleeper and an existing sleeper are mixed, or if the train is passed without connecting the connecting members of the new sleeper, a spacer or the like may be temporarily installed at the rail joint or branch. It can be accommodated by inserting it and reinforcing it temporarily.

The present invention according to claim 4 is characterized in that adjacent two
A method of laying connected ties that replaces more than one existing tie with two or more new ties that are connected to each other, by fixing the connecting members to each new tie in advance, and replacing all the existing ties in sequence. After removing from the rail, the new sleepers are laid under the rails in sequence, and after this, the new sleepers are connected by connecting the connecting members of the newly installed sleepers or by connecting the connecting members with the new sleepers abutting the connecting members. To connect.

According to the present invention, after removing all existing sleepers to be replaced from the rails, new sleepers are laid. Finally, the connecting members are connected to each other or the connecting members and the new sleepers that are in contact with the connecting members are connected to connect the new sleepers. As a result, the same work can be continuously laid and the work efficiency is improved. Further, as in the case of the present invention according to claim 1, since the sleepers are not connected to each other in advance, the individual members are light in weight and can be easily transported to the laying site, and the laying work is also easy. . Further, as described above, instead of fixing the connecting member to the sleeper at the laying site, the connecting member is firmly fixed to the sleeper in advance. As a result, even immediately after installation, a large resistance force generated between the ballast and the connecting member against vertical movement can effectively suppress vertical vibration of the sleeper. The connection members can be connected to each other by using the connection pin or the like, and the bending and shearing strength similar to that of the connection sleepers connected in advance can be secured immediately at the time of laying.

According to a fifth aspect of the present invention, there is provided a method for laying a connected sleeper tree, in which two or more existing sleepers adjacent to each other are replaced with two or more new sleepers connected to each other.
At the laying site, the connecting members are fixed by bridging between each new sleeper tree, and then all the existing sleepers to be replaced are sequentially removed from the rail, after which the connected new sleepers are laid under the rails. The present invention applies the present invention described in claim 2 in the case of replacing an existing sleeper, and exhibits the same operation and effect as the present invention described in claim 2.

According to a sixth aspect of the present invention, there are provided a first connecting tie having the first connecting member fixed to the tie in advance and a second connecting tie having the second connecting member fixed to the tie in advance. A method of laying a connected sleeper used, wherein the existing sleeper is removed from a rail and the first connecting sleeper is attached to the rail, and then the existing sleeper adjacent to the first connecting sleeper is removed from the rail. The second connecting sleeper is attached to the rail, and then the first connecting member and the second connecting member of the laid connecting sleeper are connected and fixed.

The present invention provides a method for laying two sleepers in the method for laying a connected sleeper according to claim 3 above. When carrying out the method of laying the linked sleepers of the present invention, the following configurations can be adopted.

For example, the connecting member is formed of a flat plate material, and is attached to the lower part of the sleeper with the surface portion facing upward and downward. When the first and second connecting sleepers are attached to the rail, the second connecting member is formed. May overlap the upper surface of the first coupling member, and the overlapping first and second coupling members may be connected and fixed.

Further, among the overlapping connecting members, the reinforcing member is brought into contact with at least one of the upper surface of the second connecting member and the lower surface of the first connecting member, and the first and second connecting members and the reinforcing member. It is also possible to integrally connect and fix and.

Further, the connecting member is formed of a flat plate material, and is attached to the lower part of the sleeper tree with the surface portion facing up and down. When the first and second connecting sleepers are attached to the rail, the first and second End portions of the connecting member face each other, and the connecting member is brought into contact with at least one of the upper surface and the lower surface of the connecting member so as to cover the facing end portions of the first and second connecting members. Thus, the connecting member and the first and second connecting members may be integrally connected and fixed.

The connecting member is provided with a flat surface portion formed of a flat plate material and a connecting portion projecting from the flat surface portion, and the first connecting sleeper has the connecting portion directed downward at the lower portion of the sleeper tree. The flat portion of the first connecting member is attached, and the second
The connecting sleeper of No. 2 has a configuration in which the flat portion of the second connecting member is attached to the upper part of the sleeper with the connecting portion facing downward, and when the first and second connecting sleepers are attached to the rail, The connecting portions of the first and second connecting members may be in contact with each other, and the contacting connecting portions may be connected and fixed.

When the first and second connecting ties are attached to the rails, the connecting portions of the first and second connecting members face each other from above and below and abut on each other to cover the abutting portions of the connecting portions. It is also possible to adopt a configuration in which the connection member is brought into contact with the connection portion from one side or both sides to integrally connect and fix the connection member and the connection portions of the first and second connection members.

According to a seventh aspect of the present invention, the length of extension of the connecting member from the sleeper is equal to or less than the distance between opposing side surfaces of the sleepers to be laid, and the first and second connecting members are connected. When the sleeper is attached to the rail, the connecting member is configured not to intersect with the existing sleeper or the connecting sleeper.

When the first connecting tie is attached to the rail after removing one of the existing ties from the rail, if the first connecting member extending from the connecting tie is too long, it will contact the adjacent existing tie. For this reason, there arises a problem that the connecting sleepers cannot be fixed to the rails at the prescribed intervals. Similarly, when trying to attach the second connecting sleeper to the rail, a problem occurs in which the second connecting member comes into contact with the first connecting sleeper. However, according to the present invention, when the sleepers are attached to the rails at predetermined intervals, the length of the connecting members extending from the sleepers is regulated so that the connecting members of the connecting sleepers do not intersect with the adjacent sleepers. ing. As a result, the existing sleepers can be easily replaced one by one without the problem that the connecting members can be used on the adjacent sleepers.

According to the present invention of claim 8, there is provided a first connecting sleeper having a first connecting member fixed to the sleeper in advance and a second connecting sleeper having a second connecting member fixed to the sleeper in advance. It is a method of laying connected sleepers used, in which two adjacent existing sleepers are sequentially removed from the rail,
After the first connecting tie is attached to the rail, the second connecting tie is attached to the rail, after which the first connecting member and the second connecting tie of the installed connecting tie and the second
Connect and fix the connecting member. The present invention provides the above-mentioned claim 4.
The method of laying two sleepers in the method of laying the linked sleepers in FIG.

According to a ninth aspect of the present invention, the first connecting member extends across the second connecting tie, and the second connecting member extends on both sides of the second connecting tie. It is configured to be put out, the first connecting sleeper and the second
After attaching the connecting sleeper to the rail, the first and second connecting members are connected and fixed on both sides of the second connecting sleeper. The present invention more concretely shows a configuration for carrying out the laying method of the eighth aspect. According to the present invention, since the first and second connecting members are connected and fixed on both sides of the second connecting sleeper, the connecting members are firmly connected at the time of laying, and the rigidity of the connecting sleeper can be improved. it can.

In the present invention described above, when the connecting member is formed of a flat plate material, the width of the connecting member is preferably in the range of 0.5 to 1 times the width of the sleeper. When the width of the connecting member is less than 0.5 times the width of the sleeper, the contact area between the connecting member and the ballast is small, and the effect of suppressing the vertical movement of the sleeper by the connecting member is reduced. Further, when the width of the connecting member exceeds the width of the sleeper, the contact area between the connecting member and the ballast is large, and the effect of suppressing the vertical movement of the sleeper by the connecting member is increased, but on the other hand, the multi-tie tamper pierces the roadbed. When it is hardened, there is a problem that the tab hits.

In addition, in the configuration exemplified in the present invention as set forth in claims 6 to 9, between the adjacent connecting ties, between the second connecting member and the lower surface of the rail attached to the tie. Alternatively, a spacer is provided on the upper surface of the second connecting member, the reinforcing member or the connecting member to fill the space between the lower surface of the rail and the reinforcing member or the connecting member that abuts on the upper surface of the second connecting member. be able to. According to this structure, the load applied to the rail is distributed not only to the sleeper but also to the connecting member via the spacer.
As a result, the concentration of the load on the sleeper portion is suppressed, the occurrence of consolidation is reduced, the vertical movement is suppressed, and the occurrence of the “flapping phenomenon” can be effectively suppressed.

Further, in the configuration exemplified in the present invention as set forth in claims 6 to 9, a lower surface of the first connecting member or a reinforcing member attached to the lower surface of the first connecting member,
Alternatively, it is possible to adopt a configuration in which a wear resistant member is attached to the lower surface of the connection member attached to the lower surfaces of the first and second connecting members. By attaching a wear resistant member,
Wear and damage of each member due to ballast can be suppressed, and durability is improved.

Further, in the above-mentioned present invention, it is preferable that all members including the sleeper and the connecting member are made of synthetic wood made of glass long fiber reinforced hard synthetic resin foam. Examples of the type of foam resin include urethane resin,
Hard thermosetting resins such as epoxy resin, vinyl ester resin, unsaturated polyester resin, and phenol resin are preferably used. In addition, in order to improve the compression strength and reduce the cost, the foamed resin contains calcium carbonate,
Inorganic fillers such as gypsum, talc, aluminum hydroxide and clay, and lightweight aggregates such as shirasu balloon, perlite and glass balloon may be added.

Fibers for reinforcing the hard resin foam of the plate material include, for example, inorganic fibers such as glass fibers, carbon fibers, metal fibers and ceramic fibers, and synthetic fibers such as aromatic polyamide fibers and organic fibers such as natural fibers. However, glass fiber is suitable in terms of strength and economy. The fiber form is preferably long fiber form such as yarn, cloth, roving, roving cloth, and cross mat. If necessary, short fibers such as chips and middle fibers and hollow filler such as shirasu balloon are used together. You may. Examples of the glass fiber include glass roving, glass roving cloth, glass mat, and continuous strand mat. This fiber may be used alone, two or more layers may be laminated, or long fibers and short fibers may be mixed and used.
The most preferable material is a foam made of hard urethane resin reinforced with long glass fibers aligned in the longitudinal direction (for example, trade name "Eslon Neo-Lumber FFU" manufactured by Sekisui Chemical Co., Ltd.).

When the sleepers and the connecting members are made of synthetic wood, it is preferable that the fibers contained in the synthetic wood are oriented in the longitudinal direction of each member. In other words, the stress applied to the sleeper is mainly due to the bending moment with the rail as the fulcrum, and high bending rigidity (EI) in the longitudinal direction of the sleeper is required. By aligning the fiber direction of the synthetic wood with the longitudinal direction of the sleeper, or by making a sleeper laminated with synthetic wood with different fiber directions,
High bending rigidity can be obtained. Further, for all members including the connecting member fixed to the sleeper, it is preferable to use those cut out from the original plate so that the fiber direction is the longitudinal direction of each member.

FIG.

Connecting sleepers (first connecting sleeper)
As shown in FIGS. 1 (a) and 1 (b), 10 is a structure in which two flat plate-shaped connecting members (first connecting members) 12 are previously fixed to a prismatic sleeper 11. The sleeper 11 is made of synthetic wood and has a prismatic shape whose height is slightly lower than the width, and a fixing groove 11a is provided on the lower surface near both ends over the entire length of the sleeper 11 in the width direction. . Fixed groove 1
1a has a width that is substantially the same as the width of the connecting member 12 described below, a depth that is substantially the same as the thickness of the connecting member 12, and is provided immediately below the portion where the rail is fixed to the sleeper 11.

The connecting member 12 is made of synthetic wood, has a rectangular thin plate shape, and has a width slightly narrower than the sleeper tree 11 in this embodiment. Further, the connecting member 12 is provided with three connecting holes 12a along both longitudinal edges. The connecting sleeper 10 has an adhesive applied to the fixing groove 11a,
One end of the connecting member 12 is fitted into the fixing groove 11a so as to match the side surface of the sleeper 11 and is connected and fixed (see FIG. 1 (b)).

In this connecting sleeper 10, the sleeper 1
The length of the connecting member 12 extending from 1 is regulated.
That is, when the connecting sleepers 10 are attached to the rails at predetermined intervals similarly to the adjacent sleepers, the length of the end of the connecting member 12 abuts the side surface of the adjacent sleeper.

In this embodiment, the connecting member 12 is connected and fixed to the sleeper 11 by using an adhesive, but another connecting structure using an adhesive may be adopted. For example,
A connection hole may be provided in advance in the connection member 12 and the fixing groove 11a of the sleeper 11, and an adhesive may be poured into the connection hole and a connection pin made of synthetic wood may be driven to fix the connection. According to this structure, since the connecting pin is made of the same material as the sleeper 11 and integrally joined, it is also possible to drive a fixing nail for fixing the tie plate or the rail from above.

Connecting sleepers (second connecting sleepers)
As shown in FIGS. 2 (a) and 2 (b), 13 is a prismatic sleeper 14 to which two flat plate-shaped connecting members (second connecting members) 15 are fixed in advance. The sleeper 14 is made of synthetic wood, has the same outer shape as the sleeper 11 and has a prismatic shape whose height is slightly lower than the width, and a fixing hole penetrating in the width direction of the sleeper 14 in the lower part near both ends. 14a
Is provided. The width of the fixing hole 14a is the connecting member 15
The width is substantially the same as the width, the height is substantially the same as the thickness of the connecting member 15, and the height is provided directly below the portion where the rail is fixed to the sleeper 14.

The connecting member 15 is made of synthetic wood, has a rectangular thin plate shape, and has the same width as the sleeper 14 in this embodiment. Further, the connecting member 15 is provided with three connecting holes 15a along both longitudinal edges. The connection hole 15a is provided at a position corresponding to the connection hole 12a provided in the connecting member 12 of the connecting sleeper 10.

The connecting sleeper 13 is one in which an adhesive is poured into the fixing hole 14a and the connecting member 15 is fitted and connected and fixed (see FIG. 2 (b)). Here, the fixing hole 14
“A” is provided at a position above the lower surface of the sleeper 14 by the thickness of the connecting member 12. This makes the pillow tree 11
When the upper surface of the sleeper 14 and the upper surface of the sleeper 14 are aligned and fixed to the rail, the connecting member 15 overlaps the upper surface of the connecting member 12.

Even with this connecting sleeper 13, the sleeper 1
The length of the connecting member 15 extending from 4 is regulated. That is, when the connecting sleepers 13 are attached to the rails at predetermined intervals similarly to the adjacent sleepers, the length of the end of the connecting member 15 contacts the side surface of the connecting sleeper 10.

The connecting sleeper 13 is the sleeper 1
A prism-shaped spacer 16 is joined and fixed to the upper surface of the connecting member 15 extending from 4. The height of the spacer 16 is substantially the same as the gap between the lower surface of the rail and the upper surface of the connecting member 15 when the sleeper 14 is fixed to the rail. The length of the spacer 16 is substantially the same as the length of the connecting member 15 extending from the sleeper 14, and is fixed to the central portion in the width direction of the upper surface of the connecting member 15 in the longitudinal direction (FIG. 2).
(See (b)).

In this embodiment, the connecting member 15 is connected and fixed to the sleeper 14 by using an adhesive. However, like the connecting sleeper 10 described above, a connecting structure using connecting pins is also used. Is also good. The connecting sleeper 10 and the connecting sleeper 13 are manufactured in advance in a factory.

Next, with reference to FIGS. 3 to 5, a method of laying connected ties using the first and second connecting ties 10, 13 will be described. As shown in FIG. 3A, the existing sleeper (not shown) is removed from the rail R, and the connecting sleeper 10 is fixed to the rail R via the tie plate T. At this time, the end portions of the connecting members 12 are brought into contact with the side surfaces of the adjacent existing sleeper trees M, so that the connecting sleeper tree 10 and the existing sleeper trees M are connected.
Since the interval between and is fixed, positioning can be performed easily.
In this case, since the tip of the connecting member 12 only contacts the side surface of the existing sleeper tree M, the connecting sleeper tree 10 can be laid while the adjacent existing sleeper tree M is still laid.

After the connecting sleeper 10 is attached to the rail R, the ballast around the connecting sleeper 10 is tamped with a tool such as a tamper (FIG. 5 (a),
(See (b)). As shown in FIGS. 3A and 3B, the adjacent sleeper M is removed from the rail R, and the connecting sleeper 13 is inserted into the lower portion of the rail R so that the lower surface of the connecting member 15 overlaps the upper surface of the connecting member 12. Then, it is fixed to the rail R via the tie plate T. At this time, the end of the connecting member 15 is brought into contact with the side surface of the connecting sleeper 10 so that the interval with respect to the connecting sleeper 10 is determined and positioning is easy.

After the connecting sleeper 13 is attached to the rail R, the ballast around the connecting sleeper 13 is tamped with a tamper (see FIGS. 5 (a) and 5 (b)). As shown in FIG. 3 (c), the connecting members 1 overlapped with each other.
An adhesive (a urethane resin-based adhesive is used in this embodiment) is poured into each of the connection holes 15a and 12a of 5 and 12,
The laying is completed by penetrating the connection holes 15a and 12a and driving the connection pin P into the connection hole.

When the connecting sleepers 10 and 13 are laid and connected, the spacer 16 contacts the lower surface of the connecting portion of the rail R, as shown in FIG. As a result, the load of the rail R is distributed not only to the sleepers 11 and 14 but also to the connecting members 15 and 12 via the spacers 16, and local compaction is suppressed.

Also, as described above, the connecting sleeper 1
The connecting members 12 and 15 are firmly fixed to 0 and 13 in advance. As a result, as shown in FIG. 4, the connecting sleepers 10 and 13 and the connecting members 12 and 15 are integrated to increase the contact area with respect to the ballast, and at the time of laying, a large resistance to vertical movement is exhibited and the “flapping phenomenon” occurs. It is possible to effectively suppress the occurrence of. Further, since the connecting members 12 and 15 are connected to each other by the connecting pin P, load resistance in the bending and shearing direction (lateral direction) of the connecting members 12 and 15 can be exerted immediately at the time of laying, and the rail R can expand and contract. It is possible to effectively prevent the movement of the connecting sleepers 10 and 13 associated with the above.

The present inventors prototyped the first and second connecting sleepers 10 and 13 having the above-mentioned construction and measured the time required for laying. As a result, it took a total of about one hour to remove the existing sleeper M, fix the connecting sleeper 10 (13) to the rail R, and tamper the ballast. Therefore, if the train passes at intervals of 30 minutes or more, the connecting sleepers 10 and the connecting sleepers 13 are sequentially replaced and laid every hour in accordance with the intervals between passing trains, and finally the connecting member 12,
The installation can be completed by connecting 15 together. As a result, it is possible to perform the work in the daytime even though the sleepers are connected, without being forced to perform the work in the operation stoppage period at night unlike the related art.

As shown in FIG. 37A, three connecting sleepers 71 are placed orthogonally on the two connecting members 72 arranged in parallel. In this case, the connecting plate 72a of the connecting member 72 is fitted into the fixing groove 71a provided in the connecting sleeper 71 and placed. Then, each connection hole 72 of the connecting member 72
An epoxy resin-based or urethane resin-based adhesive is poured into the connection hole 71b of the connecting sleeper 71 through d, and the connection pin P is driven. The assembly work may be performed by covering the connecting sleeper 71 with the connecting member 72.

As shown in FIG. 37 (b), the connecting member 7
Two spacers 73 are provided between the two positioning members 72b.
And the positioning member 72c of the connecting member 72
Two spacers 74 are inserted between them. Spacer 7
Reference numerals 3 and 74 each have a prismatic shape, and through holes 73a and 74a are formed in the vertical direction at portions corresponding to the connection holes 72e provided in the connecting plate 73a. In addition, the spacer 73,
An adhesive may be applied between 74 and the connecting plate 73a.

As shown in FIG. 38 (a), another two connecting members 72 are placed on the connecting sleeper 71 so as to face the two connecting members 72 arranged below. In this case, the connecting plate 72a of the connecting member 72 is connected to the connecting sleeper 71.
It is inserted into the fixed groove 71a provided in the and mounted. Then, an epoxy resin-based or urethane resin-based adhesive is poured into the connection hole 71b of the connecting sleeper 71 through the six connection holes 72d of the connecting member 72, and the connection pin P is driven.

Eight connection holes 72 of the lower connecting member 72
A bolt B is inserted into each of e, and a nut N is screwed into and fastened to the bolt B protruding from the connection hole 72e of the upper connecting member 72. In this case, as shown in FIG. 39, if the connecting hole 72e of the upper connecting member 72 is configured such that the diameter of the connecting plate 72a is approximately half of the thickness of the connecting plate 72a in advance and the nut N is depressed, the connecting member 72 of the connecting member 72 is depressed. The nut N does not project upward. It is also possible to adopt a structure in which the nut N is projected from the connecting member 72. In this case, the height of the gap between the upper surface of the connecting member 72 and the lower surface of the rail is substantially the same as that of the nut N.
It is possible to adopt a structure in which a spacer having an opening at the projecting portion is connected and fixed to the upper surface of the connecting member 72.

When the assembly of the linked sleepers 70 is completed in this way, next, three adjacent existing sleepers (not shown) are sequentially removed from the rails. Then, the assembled linked sleeper 70 is inserted under the rail and fixed to the rail to complete the laying work.

As described above, in the present embodiment, since the linked ties 70 are assembled at the laying site, they are extremely lightweight and easy to handle, easy to transport, and easy to assemble as compared with the previously assembled linked ties. Further, as described above, the connecting sleeper 71 and the connecting plate 72a are connected by the connecting pin, and the upper and lower connecting members 72 are fastened by the bolt B and the nut N. Normally, the connection with the connecting pin has a small load bearing force in the direction of driving the connecting pin until the adhesive is completely cured. However, in the present embodiment, the bolt B and the nut N are fastened to each other to compensate for the decrease in the vertical load bearing force immediately after assembly. Thereby, when the assembly is completed, it is possible to secure the same strength as that of the pre-assembled connected sleeper. Further, since the connecting member 72 and the connecting sleeper 71 are fixed by the connecting pin P, it is also possible to drive a fixing nail for fixing the tie plate or the rail from above.
Further, in the present embodiment, it is possible to adopt a field assembly method in which the existing sleeper is first removed, the lower connecting member is arranged, then the sleeper and the spacer are arranged, and then the upper connecting member is attached. In addition, in the said 1st-9th embodiment, although connecting members were connected using the connection pin, the bolt and nut used in this embodiment may be used instead of the connection pin.
