EMBODIMENT OF THE INVENTION Hereinafter, with reference to an accompanying drawing, the form for implementing the track|orbit of the rail-based transportation system by this indication is demonstrated. However, the present disclosure is not limited to this embodiment.
(orbital configuration)

(Configuration of rail transportation system)
As shown in FIGS. 1 and 2, the track-based transportation system 1 includes a track 3 on which guide rail-type vehicles 2 run. The track 3 extends in an extension direction Da (direction perpendicular to the paper in FIG. 1) along a predetermined route. The track 3 is configured by arranging a plurality of track units 5 side by side in the stretching direction Da. The track unit 5 is mainly arranged in a straight section of the track 3. The track unit 5 has a predetermined length (for example, about 15 m to 30 m) in the stretching direction Da. The track unit 5 is manufactured in advance into a predetermined shape at a factory. The track unit 5 includes a track body 10, a guide 20, and a position regulating section 30. In the track unit 5, the track body 10 and the guide 20 are fixed so as to be integrated.

(Configuration of orbital body)
The track body 10 is formed to have a predetermined length in the stretching direction Da. A plurality of track bodies 10 are arranged adjacent to each other in the stretching direction Da. The track body 10 is made of precast concrete. The track body 10 integrally includes a roadbed 11 and a wall portion 12. The track body 10 is formed by embedding reinforcing bars in concrete.

The roadbed 11 is formed along a plane intersecting the vertical direction Dv. A running surface 11f on which the vehicle 2 runs is formed on the upper surface of the roadbed 11. The running surface 11f extends in the stretching direction Da. The running surfaces 11f are formed at two locations apart in the width direction Dw so as to correspond to the positions of the running wheels 2f of the vehicle 2. The running surface 11f is formed as a flat surface over the entire surface so that the running wheels 2f can roll thereon. Note that the running surfaces 11f are not limited to being formed apart in the width direction Dw. The running surface 11f may be formed to be continuous in the width direction Dw, and may be integrally formed from left to right.
Further, the surface of the running surface 11f is provided with grooving, roughening, etc. by a formwork to the extent that flatness is not impaired. Thereby, the surface of the running surface 11f is a surface that secures a coefficient of friction with the tire tread surface and prevents slipping during rain or the like.

The roadbed 11 is supported directly on a supporting ground (not shown) formed on the ground or via supports (not shown) on the ground. The roadbed 11 is formed by embedding roadbed reinforcing bars 15 in a roadbed concrete material 14. The roadbed reinforcing bars 15 include a plurality of main reinforcements (not shown) extending in the stretching direction Da, and roadbed shear reinforcing bars 1512 that surround the plurality of main reinforcements and are arranged along a plane orthogonal to the stretching direction Da. . Moreover, the roadbed reinforcing bars 15 further include running road reinforcing bars 1513 arranged below the running surface 11f.

The wall portions 12 are formed at both ends of the width direction Dw which intersects with the stretching direction Da (perpendicularly in this embodiment) with respect to the running surface 11f. The wall portion 12 is formed over the entire length of the roadbed 11 in the extending direction Da. The wall portion 12 is formed to extend from the roadbed 11 toward upper Dvu in the vertical direction Dv. The wall portion 12 is formed by embedding wall reinforcing bars 17 in a wall concrete material 16.

The wall portion 12 has a wall side surface 12s facing the inside Dwi in the width direction Dw, and a wall outer surface 12o facing the outside in the width direction Dw. The wall side surface 12s is the surface of the wall portion 12 facing the running surface 11f in the width direction Dw. The wall outer surface 12o is the surface facing the opposite side to the wall side surface 12s in the width direction Dw.

In this embodiment, the intermediate portion of the wall outer surface 12o in the vertical direction Dv protrudes toward the outer side Dwo in the width direction Dw. As a result, an upper inclined surface 1212 and a lower inclined surface 1213 are formed on the wall outer surface 12o. The upper inclined surface 1212 is inclined from the middle part of the wall outer surface 12o toward the upper side Dvu in the vertical direction Dv and toward the inner side Dwi in the width direction Dw. The lower inclined surface 1213 is inclined inward in the width direction Dw from the middle part of the wall outer surface 12o toward the lower side Dvd in the vertical direction Dv.

The wall portion 12 has a wall body 121 and a protruding portion 122. The wall body 121 is formed from both ends of the roadbed 11 in the width direction Dw toward the upper Dvu in the vertical direction Dv. The protruding portion 122 is formed in the middle of the wall body 121 in the vertical direction Dv. In other words, the protruding portion 122 is formed at a position away from the roadbed 11 in the upper Dvu in the vertical direction Dv. The protruding portion 122 is formed integrally with the wall body 121 so as to protrude from the wall body 121 to the inside Dwi in the width direction Dw. A space surrounded by the wall body 121 and the protruding portion 122 is formed above the protruding portion 122 in the vertical direction Dvu. A train line (not shown) is arranged in this space.

The wall reinforcing bars 17 include main body reinforcing bars 171 arranged inside the wall main body 121 and protruding part reinforcing bars 172 arranged inside the protruding parts 122. The main body reinforcing bars 171 include a plurality of main reinforcements (not shown) extending in the stretching direction Da, and shear reinforcing bars 1712 surrounding the plurality of main reinforcements and arranged along a plane orthogonal to the stretching direction Da. The protrusion reinforcing bars 172 are connected to the main body reinforcing bars 171. The protruding reinforcing bar 172 extends from the main reinforcing bar 171 so as to protrude toward the inner side Dwi in the width direction Dw.

As shown in FIG. 3, the first end surface 11a of the first side Da1 of the track body 10 in the stretching direction Da and the second end surface 11b of the second side Da2 of the track body 10 in the stretching direction Da are respectively relative to the running surface 11f. It is formed as a plane that is orthogonal to each other. That is, the first end surface 11a and the second end surface 11b are formed as flat surfaces that extend in the vertical direction Dv and the width direction Dw.

(Guide composition)
As shown in FIG. 2, a plurality of guides 20 are arranged on the walls 12 on both sides of the track 3 over the entire length of the track 3. As shown in FIG. 1, the guide 20 is capable of contacting the guide wheel 2r of the vehicle 2 with a contact surface 20f facing the running surface 11f in the width direction Dw. When the guide wheel 2r contacts the guide 20, the vehicle 2 traveling on the running surface 11f is guided to move along the track 3. The guide 20 extends in the stretching direction Da at the same height from the running surface 11f. The guide 20 is made of metal material. The guide 20 is integrally fixed to the wall 12 while being connected to the wall reinforcing bars 17 . The guide 20 of this embodiment is embedded in the protrusion 122 so that only the contact surface 20f is exposed. Thereby, in the guide 20, only the contact surface 20f faces the outside of the track body 10. The guide 20 has a surface facing opposite to the contacted surface 20f in the width direction Dw connected to the tip of the protruding reinforcing bar 172 by welding.

In this embodiment, the cross-sectional shape of the guide 20 when viewed from the extension direction Da is an inverted L-shape. The guide 20 is integrally provided with a first plate portion 201 and a second plate portion 202. The first plate portion 201 is disposed so as to be perpendicular to the width direction Dw. The first plate portion 201 has a predetermined length in the vertical direction Dv. The first plate portion 201 is formed with a contact surface 20f. The first plate portion 201 is joined to the protruding portion reinforcing bar 172. The second plate portion 202 extends from the upper end of the first plate portion 201 toward the outside Dwo in the width direction Dw. The second plate portion 202 is entirely embedded in the protruding portion 122. For example, a steel angle bar can be used for such a guide 20 having an L-shaped cross section.

As shown in FIG. 3, a plurality of guides 20 are arranged in line in the stretching direction Da with respect to one wall 12. The guide 20 has a predetermined length (for example, about 5 to 15 m) in the stretching direction Da. A plurality of guides 20 are arranged side by side with gaps s in the stretching direction Da. The width in the stretching direction Da is, for example, about 3 to 10 mm. The size of this gap s is determined by the length of the guide 20 and the difference in guide surface temperature throughout the year.

Each guide 20 has a first end 21 on the first side Da1 in the stretching direction Da and a second end 22 on the second side Da2 in the stretching direction Da from an upper Dvu to a lower Dvd in the vertical direction Dv. It is formed to be inclined from the second side Da2 to the first side Da1 in the stretching direction Da. Thereby, the guide 20 of this embodiment is formed in a parallelogram shape when viewed from the width direction Dw. That is, the first end 21 and the second end 22 are inclined parallel to each other. Note that the guide 20 may have an end face vertically formed without this inclination. In this case, the guide 20 is formed into a rectangle when viewed from the width direction Dw.

The first end 21 has a first guide upper end 21t and a first guide lower end 21b. The first guide upper end 21t is a corner located Dvu above the first end 21 in the vertical direction Dv. The first guide lower end 21b is a corner located Dvd below the first end 21 in the vertical direction Dv. The first guide lower end 21b is disposed on the first side Da1 in the extension direction Da from the first guide upper end 21t. When viewed from the width direction Dw, the first guide upper end 21t and the first guide lower end 21b are connected in a straight line.

The second end portion 22 has a second guide upper end 22t and a second guide lower end 22b. The second guide upper end 22t is a corner portion located above Dvu in the vertical direction Dv of the second end portion 22. The second guide lower end 22b is a corner portion located below Dvd in the vertical direction Dv of the second end portion 22. The second guide lower end 22b is arranged on the first side Da1 in the stretching direction Da than the second guide upper end 22t. When viewed from the width direction Dw, the second guide upper end 22t and the second guide lower end 22b are connected in a straight line.

When viewed from the width direction Dw, the straight line connecting the first guide upper end 21t and the first guide lower end 21b, and the straight line connecting the second guide upper end 22t and the second guide lower end 22b are inclined at an inclination angle θ with respect to the running surface 11f. In other words, the first end 21 and the second end 22 are inclined at an inclination angle θ with respect to the running surface 11f when viewed from the width direction Dw. The inclination angle θ is preferably about 15° to 60°.

The guides 20 adjacent to each other in the stretching direction Da include the second end 22 of the guide 20 disposed on the first side Da1 in the stretching direction Da, and the second end 22 of the guide 20 disposed on the second side Da2 in the stretching direction Da. The one end portion 21 is arranged so as to overlap when viewed from the vertical direction Dv.

At least one of the first end 21 and second end 22 of the guide 20 with respect to one wall 12 partially protrudes from the track body 10 in the stretching direction Da when viewed from the width direction Dw. It is formed like this. As shown in FIGS. 3 and 4, in this embodiment, among a plurality of guides 20 (for example, three in this embodiment) arranged on one wall 12, the first side Da1 is the closest in the stretching direction Da. The first guide lower end 21b of the guide 20A disposed in the guide 20A projects toward the first side Da1 in the stretching direction Da with respect to the first end surface 11a. On the other hand, the first guide upper end 21t of this guide 20A does not protrude from the track body 10, and is arranged on the second side Da2 in the stretching direction Da with respect to the first end surface 11a. Further, among the plurality of guides 20 disposed on one wall 12, the second guide upper end 22t of the guide 20B disposed closest to the second side Da2 in the stretching direction Da is stretched with respect to the second end surface 11b. It is arranged to protrude on the second side Da2 in the direction Da. On the other hand, the second guide lower end 22b of this guide 20B does not protrude from the track body 10, and is arranged on the first side Da1 in the stretching direction Da with respect to the second end surface 11b.

As a result, as shown in FIG. 4, among the track bodies 10A and 10B that are adjacent to each other in the stretching direction Da, the guide 20A is fixed to the track body 10B that is disposed on the second side Da2 in the stretching direction Da. The one end portion 21 is disposed at a position shifted downward in the vertical direction Dv with respect to the second end portion 22 of the guide 20B fixed to the track body 10A disposed on the first side Da1 in the stretching direction Da. .

(Configuration of position regulation section)
The position regulating portion 30 regulates the positions in the width direction Dw of the track bodies 10 that are adjacent to each other in the stretching direction Da. The position regulating section 30 is fixed to the track body 10. The position regulating portion 30 of this embodiment includes a pin 31A and an insertion recess 32.

In this embodiment, the pin 31A is inserted into the insertion recess 32 in the track main body 10A and the track main body 10B that are adjacent to each other in the stretching direction Da, so that they cannot move in the width direction Dw and the vertical direction Dv. Specifically, the pin 31A supported by the track body 10B is inserted into the insertion recess 32 of the track body 10A. Thereby, the track main body 10A and the track main body 10B are made immovable relative to each other in the width direction Dw and the vertical direction Dv. Further, the tip of the pin 31A may be chamfered to facilitate insertion during alignment.

As shown in FIG. 1, the pins 31A are arranged on the wall portions 12 arranged apart in the width direction Dw so as to sandwich the roadbed 11 from both ends in the width direction Dw. The pins 31A are formed at positions overlapping the wall portions 12 when viewed from the extension direction Da. As shown in FIG. 4, the pins 31A protrude from the track body 10 when viewed from the width direction Dw. In this embodiment, the pins 31A protrude from the first end face 11a toward the first side Da1 in the extension direction Da when viewed from the width direction Dw. The pins 31A integrally have a pin body 311 and a flange 312. The pin body 311 has a columnar shape extending in the extension direction Da. The flange 312 is formed at the middle position of the pin body 311 in the extension direction Da. The flange 312 protrudes from the pin body 311 to the outside in the radial direction of the pin body 311. The base end 3112 of the pin body 311 is inserted into a pin holding hole 33 formed in the raceway body 10. A cylindrical buffer member 35 is disposed in the pin holding hole 33. The base end 3112 is inserted inside the buffer member 35. The buffer member 35 is formed of an elastically deformable material, such as a rubber material. As a result, the pin body 311 is supported by the raceway body 10 in a state in which the tip end 3113 can swing relative to the base end 3112. The flange 312 restricts the insertion of the pin body 311 into the pin holding hole 33 (buffer member 35).

The insertion recesses 32 are arranged in the wall portion 12 so as to correspond to the pins 31A. The insertion recess 32 is formed at a position that matches the pin 31A when viewed from the stretching direction Da. In this embodiment, the insertion recess 32 is recessed from the second end surface 11b toward the first side Da1 in the stretching direction Da when viewed from the width direction Dw. A cylindrical buffer member 36 is arranged inside the insertion recess 32 . The tip portion 3113 is inserted into the buffer member 36 within the insertion recess 32 . The insertion recess 32 is formed in such a shape that it can be inserted so that the tip 3113 comes into sliding contact with the buffer member 36.

(effect)
According to the track 3 of the track-based transportation system 1 as described above, the guide 20 is fixed by welding to the wall reinforcing bars 17 embedded in the wall concrete material 16 in the wall 12. Therefore, the guide 20 is firmly fixed to the wall portion 12. As a result, the guide 20 becomes difficult to fall off from the track body 10. Furthermore, the guide 20 is disposed so as to be embedded in the wall concrete material 16 and is fixed to the wall 12 so as to be integral with it. Therefore, vibration of the guide 20 is suppressed. As a result, even if the guide 20 receives a load from the guide wheels 2r of the vehicle 2, the guide 20 becomes difficult to bend. Thereby, damage to the guide 20 itself and damage to the wall portion 12 due to vibration of the guide 20 can be suppressed. In addition, the noise generated when the guide wheel 2r collides with the guide 20 due to the vibration of the guide 20 is reduced. As a result, the guide 20 can be prevented from falling off, the effort required for maintenance can be reduced, and the noise to the surrounding environment of the orbit can be kept low.

Furthermore, in this embodiment, the guide 20 is embedded in the protrusion 122 so that only the contact surface 20f is exposed to the outside of the track body 10. Therefore, the guide 20 is very firmly fixed to the wall portion 12. As a result, the guide 20 hardly vibrates against the wall portion 12. Therefore, even if the guide 20 receives a load from the guide wheel 2r, the guide 20 hardly bends. Thereby, falling off of the guide 20 can be significantly suppressed, and the effort required for maintenance can be greatly reduced. Further, since the vibration and deflection of the guide 20 are reduced, vibration noise caused by the guide 20 is also suppressed, and noise to the surrounding environment of the orbit can be suppressed.

Moreover, the track body 10 is made of precast concrete. Thereby, the track body 10 can be manufactured in advance at a factory instead of using cast concrete on site. Therefore, the track body 10 can be formed with high precision. Furthermore, since the guide 20 is integrated with the track body 10 in advance, there is no need for metal fittings or the like to support the guide 20, and there is no need to place concrete on site. Therefore, it is possible to improve work efficiency during assembly, reduce construction costs, and shorten the construction period.

In addition, while the track bodies 10 are adjacent to each other in the extension direction Da with no gaps between them, the guides 20 are arranged with gaps s between them in the extension direction Da. The guides 20 are made of metal material and are exposed on the surface, so they expand and contract more due to changes in surface temperature than the track body 10 made of concrete material. However, by arranging the guides 20 with gaps s between them, interference between the guides 20 is suppressed even if the guides 20 expand and contract. In addition, because the track bodies 10 are adjacent to each other in the extension direction Da, it is possible to suppress the occurrence of misalignment or gaps in the running surface 11f. In addition, because the guides 20 are made of metal material, their surfaces are smooth and do not change over the long term. Therefore, wear of the elastic guide wheels that come into contact with them is also suppressed, making it possible to extend their replacement life. This also makes it possible to keep the maintenance costs associated with replacing the guide wheels low.

In addition, in the portion where the guides 20 are arranged with a gap s in the extension direction Da, the first end 21 and the second end 22 of the adjacent guides 20 overlap each other when viewed from the vertical direction Dv. As a result, the guide wheel 2r of the vehicle 2 traveling on the running surface 11f is always maintained in contact with at least one of the guides 20 adjacent in the extension direction Da. Therefore, while the vehicle 2 is traveling, the guide 20 can guide the guide wheel 2r continuously without interruption. In addition, since the gap s is formed diagonally with respect to the extension direction Da, which is the traveling direction of the vehicle 2, vibrations and noise generated when the guide wheel 2r passes through the gap s can also be suppressed.

Further, the first end portion 21 and the second end portion 22 of the guide 20 partially protrude from the wall portion 12 in the stretching direction Da when viewed from the width direction Dw. Specifically, the second guide upper end 22t protrudes from the second end surface 11b, and the first guide lower end 21b protrudes from the first end surface 11a. Therefore, during construction, first install the track body 10B with the first guide lower end 21b protruding, and then move the track body 10A with the second guide upper end 22t protruding from the upper Dvu of the vertical direction Dv to the pin 31A. It is separated and lowered toward the first side Da1 in the stretching direction Da in accordance with the protrusion. Thereafter, the insertion recess 32 is aligned with the pin 31A, and the track body 10A is moved to the second side Da2 in the stretching direction Da, and installed while fitting the insertion recess 32 onto the pin 31A. Thereby, the two track bodies 10A and 10B that are adjacent to each other in the stretching direction Da can be installed so that the guides 20 overlap each other when viewed from the vertical direction Dv even between the two track bodies 10A and 10B. It's easy to do.

Moreover, the first end surface 11a and the second end surface 11b of the track body 10 are each formed as a plane extending in the vertical direction Dv and the width direction Dw so as to be orthogonal to the running surface 11f. Thereby, compared to the case where the first end surface 11a and the second end surface 11b of the track body 10 are formed as inclined surfaces, the first end surface 11a and the second end surface 11b can be easily formed. Furthermore, when the track bodies 10 are lifted up by a crane or the like and installed adjacent to the stretching direction Da, the track bodies 10 can be brought into contact with each other by simply lowering them in the vertical direction Dv and then moving them in the stretching direction Da. It can be easily installed.

Further, the position regulating portion 30 having the pin 31A and the insertion recess 32 regulates the positions of the track bodies 10 that are adjacent to each other in the stretching direction Da in the width direction Dw and the vertical direction Dv. This prevents the positions of adjacent track bodies 10 from shifting.

In addition, by inserting the pin 31A of one track body 10B into the insertion recess 32 of the other track body 10A, the relative movement between the one track body 10B and the other track body 10A in a direction intersecting the axis of the pin 31A is suppressed. This allows the position restriction section 30 to be formed with a simple structure. Even if the track body 10 expands or contracts in the extension direction Da due to temperature changes, as long as the pin 31A is inserted in the insertion recess 32, the relative movement in a direction intersecting the axis of the pin 31A is suppressed. This suppresses the effects of expansion and contraction of the track body 10 due to temperature changes and bending of the track body 10 due to the running of the vehicle 2, and prevents the positions of adjacent track bodies 10 from shifting.

Further, the pin 31A is supported so as to be swingable in the vertical direction Dv with respect to the track body 10. Thereby, the pin 31A can absorb a positional shift between the track bodies 10 adjacent to each other in the stretching direction Da. In addition, even if the track bodies 10 are bent in a direction crossing the stretching direction Da due to thermal deformation or the like, the pins 31A swing inside the buffer members 35 and 36 to absorb the deflection of the track bodies 10. be done. These prevent the track bodies 10 adjacent to each other in the stretching direction Da from shifting in the direction intersecting the axis of the pin 31A.

Further, the guide 20 is arranged on the protrusion 122. Thereby, the guide 20 fixed to the wall reinforcing bars 17 is supported by the concrete material forming the protrusion 122. Therefore, in order to support the guide 20, there is no need to increase the thickness of the entire wall portion 12 in the width direction Dw. Therefore, the guide 20 can be installed at low cost while saving space on the wall portion 12.

(First modification of the embodiment)
In the above embodiment, in the position regulating portion 30, the pin 31A is arranged so as to overlap the wall portion 12 at both ends in the width direction Dw with respect to the roadbed 11 when viewed from the stretching direction Da. However, the arrangement of the position regulating section 30 is not limited to such a structure.

For example, as shown in FIG. 5, the pin 31A and the insertion recess 32 may be arranged on the outer protrusion 125 of the track body 10. The outer protrusion 125 is disposed on the outer side of the wall body 121 in the width direction Dw. The outer protrusion 125 is fixed to the lower inclined surface 1213. Thereby, the outer protrusion part 125 is arranged in the track body 10 so as to protrude outward in the width direction Dw with respect to the wall part 12. In other words, the outer protrusion 125 is arranged at a position that does not overlap the wall 12 when viewed from the stretching direction Da, and has a structure that is firmly fixed to the track body 10 by a fastening means such as a removable bolt. There is.

According to such a configuration, the pin 31A is disposed outside the wall portion 12 in the width direction Dw. As a result, when performing maintenance or the like on the pin 31A, the pin 31A can be accessed by removing the outer protrusion 125 from the track body 10 without shifting the track bodies 10 themselves, which are arranged back and forth in the stretching direction Da. Thereby, the maintainability of the position regulating section 30 can be improved.

(Second modification of embodiment)
In the above embodiment, the pin 31A is inserted inside the buffer members 35 and 36 to allow the tip portion 3113 to swing. However, the structure that allows the pin 31A to swing is not limited to a structure that includes such a buffer member.

For example, as shown in FIGS. 6 and 7, in the modified position regulating portion 301, the pin 31B includes a shaft portion 37 and a pin body 38. The shaft portion 37 is fixed to the track body 10B. The shaft portion 37 has a rotating shaft 37s extending in the width direction Dw. The pin body 38 is connected to the rotating shaft 37s. The pin body 38 is configured so that the tip portion 38s can swing only in the vertical direction Dv by rotating together with the rotating shaft 37s. An insertion recess 39 into which a pin 31B can be inserted is formed in the track body 10A.

In this configuration, similar to the above embodiment, the pin 31B can absorb the misalignment between adjacent track bodies 10 in the extension direction Da. Even if the track bodies 10 are warped in a direction intersecting the extension direction Da due to thermal deformation or the like, the pin 31B rotates together with the rotation shaft 37s and the tip 38s swings, absorbing the warping of the track body 10. As a result, the track bodies 10 adjacent to each other in the extension direction Da are prevented from being misaligned in a direction intersecting the axis of the pin 31B.

(Third modification of embodiment)
In the above embodiment, the position regulating section 30 has the pin 31A as a structure for regulating the position in the width direction Dw and the vertical direction Dv, but the position regulating section is not limited to such a structure. . That is, the position regulating portion may have any structure as long as it can regulate the positions of the track bodies 10 adjacent to each other in the stretching direction Da in at least the width direction Dw.

For example, as shown in FIGS. 8 and 9, the position regulating section 302 includes a trajectory guide plate 41. The track guide plate 41 is firmly fixed to one wall portion 12 of the track body 10 adjacent to each other in the extending direction Da by fastening means such as bolts. The track guide plate 41 is formed to protrude from the track body 10 in the extending direction Da. In this embodiment, the track guide plate 41 is arranged only on the first end face 11a with respect to the wall portion 12 so as to protrude from the first end face 11a of the track body 10B. The orbit guide plate 41 is fixed to the lower inclined surface 1213. The orbit guide plate 41 is a flat member. The track guide plate 41 is capable of contacting the wall outer surface 12o of the other wall portion 12 of the track body 10 adjacent to each other in the extending direction Da. In this embodiment, the track guide plate 41 is capable of contacting the lower inclined surface 1213 at the second end surface 11b of the track body 10A.

In such a configuration, by bringing the track guide plate 41 of one track main body 10B into contact with the lower inclined surface 1213 of the other track main body 10A, one track main body 10B and the other track main body 10A are aligned in the width direction. Movement relative to Dw is suppressed. Thereby, the position regulating portion 301 can be formed with a simple structure. Further, the track guide plate 41 is disposed outside the wall portion 12 in the width direction Dw. As a result, when performing maintenance or the like of the track guide plate 41, the track guide plate 41 can be accessed from the outside Dwo in the width direction Dw without shifting the track bodies 10 themselves, which are arranged back and forth in the stretching direction Da. Thereby, the maintainability of the position regulating section 302 can be improved. In addition, when installing the track body 10A, positioning can be achieved by simply lowering the track body 10A from above with respect to the track body 10B, so that it is possible to shorten the process and reduce costs.

Further, in the above embodiment, the track body 10 of the track 3 is provided with only one set of running surfaces 11f in the width direction Dw, but the present invention is not limited to this. The track body 10 may include a plurality of sets of running surfaces 11f in the width direction Dw. For example, as shown in FIG. 10, in the case of a structure having two sets of running surfaces 11f, an intermediate wall 19 is arranged as a wall between the two sets of running surfaces 11f in the width direction Dw. . It is preferable that guides 20 are disposed on both side surfaces of the intermediate wall portion 19 in the width direction Dw, respectively.

Further, in the above embodiment, the guide 20 has an L-shaped cross section, but the guide 20 is not limited to this. For example, the guide 20 may have a flat plate shape having only the first plate portion 201. A belt-shaped steel plate can be used for such a guide 20. Further, the guide 20 may have a C-shaped cross section, in addition to the first plate part 201 and the second plate part 202, further including a third plate part disposed below the first plate part 201. For such a guide 20, a C-type steel can be used.

<Additional notes>
The track 3 of the track-based transportation system 1 described in each embodiment is understood, for example, as follows.

(1) The track 3 of the rail transportation system 1 according to the first aspect includes a roadbed 11 forming a running surface 11f extending in the extending direction Da of the track 3, and intersecting the running surface 11f in the extending direction Da. The track main body is formed by embedding reinforcing bars in concrete material, and has a wall portion 12 formed to extend in the vertical direction Dv from the roadbed 11 at an outer side Dwo in the width direction Dw, and extends in the extending direction Da. 10, disposed on the wall side surface 12s facing the running surface 11f of the wall portion 12 in the width direction Dw, extending in the stretching direction Da, and integrally connected to the wall portion 12 while being connected to the reinforcing steel. A fixed guide 20 is provided.

Thereby, the guide 20 is firmly fixed to the wall portion 12. As a result, the guide 20 becomes difficult to fall off from the track body 10. Furthermore, since the guide 20 is integrally fixed to the wall portion 12, vibrations of the guide 20 can be suppressed. As a result, even if the guide 20 receives a load from the vehicle 2, the guide 20 becomes difficult to bend. Thereby, damage to the guide 20 itself and damage to the wall portion 12 due to vibration of the guide 20 can be suppressed. These can prevent the guide 20 from falling off and reduce the effort required for maintenance. Further, by suppressing the vibration of the guide 20, the noise accompanying the vibration is also reduced, and the noise to the environment surrounding the orbit can be suppressed.

(2) The track 3 of the rail-based transportation system 1 according to the second aspect is the track 3 of the rail-based transportation system 1 of (1), in which the guide 20 has the running surface 11f in the width direction Dw. Only the facing contact surface 20f may face the outside of the track body 10.

Thereby, the guide 20 is fixed very firmly to the wall portion 12. As a result, the guide 20 hardly vibrates against the wall portion 12. Therefore, the guide 20 hardly bends. Thereby, falling off of the guide 20 can be significantly suppressed, and the effort required for maintenance can be greatly reduced.

(3) The track 3 of the rail-based transportation system 1 according to the third aspect is the track 3 of the rail-based transportation system 1 of (1) or (2), wherein the track main body 10 extends in the extending direction Da. A plurality of guides 20 may be formed with a predetermined length and arranged adjacent to each other in the stretching direction Da, and a plurality of guides 20 may be arranged side by side with gaps s in the stretching direction Da.

As a result, the guides 20 are arranged with a gap s between them, so that interference between the guides 20 is suppressed even when the guides 20 expand and contract. In addition, because the track body 10 is adjacent to each other in the extension direction Da, misalignment or gaps in the running surface 11f are suppressed.

(4) The track 3 of the rail-based transportation system 1 according to the fourth aspect is the track 3 of the rail-based transportation system 1 according to any one of (1) to (3), and the guide in the extending direction Da. The first end 21 of the first side Da1 of the guide 20 and the second end 22 of the second side Da2 of the guide 20 in the stretching direction Da are arranged in the direction from the upper Dvu to the lower Dvd in the vertical direction Dv. The guides 20 that are formed to be inclined toward the first side Da1 in the stretching direction Da and that are adjacent to each other in the stretching direction Da are the same as the guides 20B arranged on the first side Da1 in the stretching direction Da. The second end portion 22 and the first end portion 21 of the guide 20A disposed on the second side Da2 in the stretching direction Da may be arranged to overlap when viewed from the vertical direction Dv.

Thereby, the guide wheel 2r of the vehicle 2 running on the running surface 11f is always maintained in a state in which it is in contact with at least one of the guides 20 adjacent to each other in the stretching direction Da. Therefore, while the vehicle 2 is running, the guide 20 can continuously guide the guide wheel 2r without interruption. Furthermore, since the gap s is formed obliquely with respect to the stretching direction Da, which is the traveling direction of the vehicle 2, vibrations and noise generated when the guide wheel 2r passes through the gap s can also be suppressed.

(5) The track 3 of the track-based transportation system 1 according to the fifth aspect is the track 3 of the track-based transportation system 1 of (4), and at least one of the first end 21 and the second end 22 of the guide 20 may be formed so as to protrude partially from the track body 10 in the extension direction Da when viewed from the width direction Dw.

Thereby, the two track bodies 10A and 10B that are adjacent to each other in the stretching direction Da can be installed so that the guides 20 overlap each other when viewed from the vertical direction Dv even between the two track bodies 10A and 10B. It's easy to do.

(6) The track 3 of the rail-based transportation system 1 according to the sixth aspect is the track 3 of the rail-based transportation system 1 according to any one of (1) to (5), and the track in the extension direction Da. The first end surface 11a of the first side Da1 of the main body 10 and the second end surface 11b of the second side Da2 of the track main body 10 in the stretching direction Da are formed as surfaces perpendicular to the running surface 11f. Good too.

This makes it easier to form the first end face 11a and the second end face 11b of the track body 10 compared to when the first end face 11a and the second end face 11b of the track body 10 are inclined. Furthermore, when the track body 10 is installed adjacent to each other in the extension direction Da, the track body 10 can be easily installed in a state where they are in contact with each other simply by moving them in the vertical direction Dv.

(7) The track 3 of the rail transport system 1 according to the seventh aspect is the track 3 of the rail transport system 1 according to any one of (1) to (6), and is fixed to the track main body 10. , the track body 10 may further include a position regulating portion 30 that regulates the positions in the width direction Dw of the track bodies 10 that are adjacent to each other in the stretching direction Da.

Thereby, by inserting the pin 31A of one track body 10B into the insertion recess 32 of the other track body 10A, one track body 10B and the other track body 10A are moved in a direction intersecting the axis of the pin 31A. Movement relative to is suppressed. Thereby, the position regulating portion 30 can be formed with a simple structure. Further, even if the track body 10 expands or contracts in the stretching direction Da due to temperature changes, as long as the pin 31A is inserted into the insertion recess 32, relative movement in the direction intersecting the axis of the pin 31A is suppressed. This suppresses the effects of expansion and contraction of the track body 10 due to temperature changes and deflection of the track body 10 due to running of the vehicle 2, and prevents the positions of adjacent track bodies 10 from shifting.

(9) The track 3 of the rail-based transportation system 1 according to the ninth aspect is the track 3 of the rail-based transportation system 1 of (8), and the pin 31A is at least the It may be possible to swing in the vertical direction Dv.

Thereby, the pin 31A can absorb a positional shift between the track bodies 10 adjacent to each other in the stretching direction Da. Furthermore, even if the track bodies 10 are bent in a direction intersecting the stretching direction Da due to thermal deformation or the like, the deflection of the track bodies 10 is absorbed by the swinging of the pins 31A. These prevent the track bodies 10 adjacent to each other in the stretching direction Da from shifting in the direction intersecting the axis of the pin 31A.

(10) The track 3 of the rail-based transportation system 1 according to the tenth aspect is the track 3 of the rail-based transportation system 1 of (8) or (9), wherein the track body 10 is attached to the wall portion 12.

As a result, the pin 31A is disposed on the outside of the wall portion 12 in the width direction Dw. the result. When performing maintenance or the like on the pin 31A, the pin 31A can be accessed by removing the outer protrusion 125 from the outer side Dwo in the width direction Dw without shifting the track bodies 10 themselves, which move back and forth in the stretching direction Da. Thereby, the maintainability of the position regulating section 30 can be improved.

(11) The track 3 of the track-based transportation system 1 according to the eleventh aspect is the track 3 of the track-based transportation system 1 of (7), in which the position regulating unit 302 is fixed to one of the wall portions 12 of the track body 10 adjacent to each other in the extension direction Da and has a track guide plate 41 formed to protrude from the track body 10 in the extension direction Da, and the track guide plate 41 may be fixed to a wall outer surface 12o facing the opposite side to the wall side surface 12s in the width direction Dw on one side of the track body 10, and be capable of contacting the wall outer surface 12o of the other wall portion 12 of the track body 10 adjacent to each other in the extension direction Da.

As a result, the track guide plate 41 of one track body 10B is lowered on the other track body 10A so that it comes into contact with the lower inclined surface 1213, thereby preventing the one track body 10B and the other track body 10A from moving relatively in the width direction Dw. This allows the position regulation portion 301 to be formed with a simple structure, which shortens the installation time and process, as well as reducing costs.
