  The present invention relates to a planting installation structure provided on a track.

  In recent years, there are an increasing number of cases where planting for the purpose of greening is installed in railway tracks such as railways and trams.

As an example of greening the track of a tram (track), for example, there are planting installation structures shown in Patent Documents 1, 2, and 3.
In these planting installation structures, a concave pallet is placed in an area between the left and right rails (hereinafter referred to as the “gauge area”), and soil for plant cultivation and planting plants are placed in the pallet. It is what was contained.

  These pallets are fixed to the sleepers that support the left and right rails with screw nails or the like (for example, refer to Patent Documents 1 and 2), or the abdominal portion connecting the rail base and the head in the area between the rails. It is fixed by being fitted into a recess (for example, see Patent Document 3).

  Patent Document 4 also discloses a technique for providing planting in the area between the rails for the purpose of reducing noise caused by trains on a track using a so-called “ladder sleeper” that has been increasingly employed in recent years. Has been.

“Ladder sleepers” are ladder sleepers arranged along the track direction (direction in which the rail R extends) as shown in FIG. 10, and are vertical concrete beams that support the left and right rails R and R, respectively. (Vertical sleepers) 1 and 2 are provided separately for the left and right rails R and R, respectively. The left and right vertical beams 1 and 2 extend in the line direction immediately below the corresponding rail R, and the vertical beams 1 and 2 are connected and integrated by a connecting portion 3 in the line width direction (direction perpendicular to the line). Has been.
The vertical beams 1 and 2 may be placed on a concrete roadbed via an elastic body or the like, or may be placed on a ground roadbed and held by quarry piled up around.

  In addition, the connection part 3 which connects between the longitudinal beams 1 and 2 in "Ladder sleeper" is a product made from a steel pipe, and the connection part 3 is usually provided with the predetermined space | interval in the track direction.

In this patent document 4, for example, as shown in FIG. 11A, a technique is disclosed in which a concave pallet 10 for greening is used.
The pallet 10 is fixed in a state where both end portions 10b in the line width direction are in contact with the abdominal portions of the left and right rails R and R and are placed on the upper surfaces of the vertical beams 1 and 2 via the elastic member 11. The The soil 5 is accommodated in the concave portion 10a of the pallet 10, and the plant 6 is planted in the soil.

Further, as shown in FIG. 11B, auxiliary support plates 13 that are separate from the pallet 10 are provided below the concave pallet 10, and cross sections are provided at both ends of the auxiliary support plate 13 in the line width direction. Some have an L-shaped locking member 14 attached thereto. The pallet 10 is fixed on the auxiliary support plate 13 via the elastic member 12.
The pallet 10 is fixed to the in-gauge area by fitting the locking member 14 to the opposite inner edges 1a and 2a of the vertical beams 1 and 2 and fixing the auxiliary support plate 13 between the vertical beams 1 and 2. Is done.
In addition, the pallet 10 is set to have a width wider than the auxiliary support plate 13 from the viewpoint of increasing the greening area by covering a wider area in the gauge, and the space (ring road) S through which the wheel flange passes is set. As long as it is not obstructed, it reaches the vicinity of the rail R (for example, see Patent Document 4).

Japanese Unexamined Patent Publication No. 2007-1111030 (FIG. 1-6, page 6) Japanese Unexamined Patent Publication No. 2004-137683 (page 13, FIG. 1-7) Japanese Patent Laying-Open No. 2005-41 (FIG. 1-2, page 13) JP-T-2008-503666 (page 13-14, Fig. 9-13)

  As described above, in the case of the track structure in which the vertical beams 1 and 2 made of concrete are respectively provided directly below the left and right rails R and R, and the vertical beams 1 and 2 are connected by the connecting portion 3, Patent Document 1 , 2 planting installation structure cannot be adopted. This type of pallet is based on the premise that the pallet is fixed to the sleeper with screw nails, so it cannot handle the vertical beams 1 and 2 made of concrete, and the pallet cannot be fixed to the in-gauge area as it is. .

  In addition, since the planting installation structure of Patent Document 3 is intended for a special grooved rail for a streetcar or the like, a ring road S is secured for a normal rail R having no groove. It is necessary to take separate measures to do this.

  In this respect, according to the planting installation structure of FIGS. 11 (a) and 11 (b), the notch 10c for securing the ring road S and the pallet 10 having a gap are fitted between the abdominal portions of the left and right rails R. Or the pallet 10 is fixed to the in-gauge area via an auxiliary support plate 13 fitted between the inner edges 1a and 2a of the left and right vertical beams 1 and 2, so that the concrete vertical beam 1 , 2 can be used for track structures such as “Ladder sleeper”.

However, the pallet 10 covers the fastening device 4 (a jig for fixing the rail R so as not to move with respect to the longitudinal beams 1 and 2) provided on the longitudinal beams 1 and 2; There is a problem that the pallet 10 has to be removed from the track each time the apparatus 4 is inspected.
The pallet 10 has a considerable weight when the members constituting the pallet 10 and the soil 5 accommodated in the pallet 10 are combined, and the attachment and detachment thereof requires considerable labor and labor.

  Therefore, the present invention has a planting installation structure in which there are less obstacles to the maintenance and inspection of the track in the track structure in which the vertical beams made of concrete are directly below the left and right rails, and the vertical beams are connected to each other by a connecting portion. The task is to do.

  In order to solve the above-described problems, the present invention has concrete vertical beams directly below the left and right rails, the vertical beams are connected by a connecting portion, and a fastening device is connected to each of the vertical beams. In the planting installation structure in which a pallet having a recess for planting installation is arranged between the left and right rails, a part of the pallet is below the upper surface of each vertical beam. A main body portion to be inserted, and a locking portion protruding from the main body portion on both sides in the line width direction, and the concave portion is provided on an upper surface of the main body portion, and the locking portion is a track of each longitudinal beam. Adopting a planting installation structure characterized in that it is placed on the upper surface of each longitudinal beam between the inner edge in the width direction and the inner edge in the line width direction of the fastening device, and the fastening device is opened upward did.

When arranging the pallet in the gauge area, between the inner edge of each vertical beam and the fastening device (fastening device in the gauge area) for the pair of vertical beams that support the left and right rails, that is, the fastening device Since the engaging portion of the pallet is placed on the upper surface of each vertical beam as long as the upper portion is not covered, the pallet does not hinder maintenance and inspection of the fastening device. For this reason, it can be set as the planting installation structure with few troubles in the maintenance inspection of a track.
That is, in this configuration, the locking portion of the pallet is placed on the upper surface of each vertical beam in a portion inside the line connecting the inner edges in the line width direction of the plurality of fastening devices arranged in parallel in the line direction. Become.

In addition, you may make it mount the latching | locking part of a pallet on the upper surface of each vertical beam in the state which entered between the said fastening apparatuses adjacent to a track direction.
In other words, since the fastening device is provided intermittently along the line direction, if the space between the fastening device and the fastening device is utilized to place the locking portion of the pallet, While securing a large placement area, the pallet can be arranged without covering the upper part of the fastening device.

  That is, the configuration has concrete vertical beams directly under the left and right rails, the vertical beams are connected to each other by a connecting portion, and the rail is fixed to the vertical beams via a fastening device, In the planting installation structure in which a pallet having a recess for planting installation is arranged between the left and right rails, the pallet has a main body part of which enters below the upper surface of each vertical beam, and the main body Engaging portions projecting on both sides in the line width direction from the portion, the recess is provided on the upper surface of the main body portion, and the engaging portions are arranged vertically between the fastening devices adjacent in the line direction. It is the structure which is mounted on the upper surface of a beam and the said fastening device is open | released upwards.

  Thus, a configuration in which the pallet locking portion is placed between the inner edge of each vertical beam and the inner edge of the fastening device, and a configuration in which the pallet locking portion is placed between the fastening devices adjacent in the line direction. May have a configuration in which one of them is employed alone, or a configuration in which both are used together.

  If both are used in combination, for example, a fastening device that is intermittently arranged along the line direction can be avoided, and the portion without the fastening device can be inserted into the portion close to the rail. It is possible to secure the maximum area of the locking portion by keeping the locking portion in a relatively inner range so that a portion of the fastening device does not cover the fastening device. it can. If the area of the locking part is large, the mounting area on the vertical beam increases and the pallet becomes stable.

Further, in each of these configurations, a configuration is adopted in which both ends of the main body in the line width direction are opposed to the inner end surfaces of the vertical beams in the line width direction so that the pallet is positioned in the line width direction. be able to.
Since the main body part enters below the upper surface of the vertical beam, the pallet can be easily positioned by making the end of the inserted part face the vertical beam. In addition, the line width direction both ends of the main body part and the line width direction inner side end surfaces of the vertical beams may be opposed to each other while being in contact with each other, or are opposed to each other with a predetermined gap therebetween. It may be.

  The material of the pallet which consists of these each structure can be selected freely, for example, can also be made from metal, resin (for example, fiber reinforced resin), concrete, etc.

  Further, if the connecting portion is provided at a position lower than the lower surface of the main body portion, the connecting portion does not hit the pallet when the pallet is placed in the gauge area. For this reason, it is convenient when the pallet is continuously arranged along the track direction.

  In addition, although the connection part in these each structure is a product made from a steel pipe in the case of "ladder sleeper", for example, it can also be made from other raw materials, for example, a deformed steel bar. In addition, an aspect in which the connecting portion is made of concrete is also conceivable. That is, a pair of concrete vertical beams may be connected to each other by a concrete connecting portion, and the pair of vertical beams and the connecting portion may be integrally manufactured with concrete.

Furthermore, the upper surface of the latching | locking part of the said pallet can also be comprised with a flat surface. The main body of the pallet has a concave portion for planting installation, and soil and plants are accommodated in the concave portion, so that the maintenance manager may not be able to walk on that portion.
In this respect, the flat surface can be used as a space for walking by making the upper surface of the engaging portion protruding from the main body portion in the track width direction into a flat surface. That is, the maintenance manager can walk in the track without stepping on the soil or planting part. In addition, since the latching | locking part is supported by the vertical beam just under it, it is convenient on design that a pedestrian's weight is added to the latching | locking part on strength.

  Moreover, the following structure can be employ | adopted as a planting installation structure which consists of another structure.

  That is, there are concrete vertical beams directly under the left and right rails, and the vertical beams are connected to each other by a connecting portion, and the rails are fixed to the vertical beams via fastening devices, respectively. In the planting installation structure in which a pallet having a recess for planting installation is arranged, a holding member that rises upward is provided on the upper surface of each vertical beam inside the left and right rails, and the holding member is fastened Provided inside the apparatus, both ends of the pallet in the line width direction are placed on the upper surface of each vertical beam, and the pallet is positioned in the line width direction by the holding member. It is a planting installation structure.

By adopting a configuration in which the holding member provided on the vertical beam positions the pallet in the line width direction, the pallet only has to be placed on the upper surface of the vertical beam inside the holding member at both ends in the line width direction. Can complete the installation. Moreover, since the holding member is provided inside the fastening device, the pallet does not cover the fastening device.
The holding member may be continuous or intermittent along the line direction. For example, in addition to a shaft-like member or a plate-like member that protrudes upward from the upper surface of the vertical beam, it is possible to use an angle member having an L-shaped cross section in particular.

The planting installation structure in which the pallet is positioned by this holding member can be provided not only in the gauge area as described above but also in the gauge outside area.
That is, the configuration is such that a holding member that rises upward is provided on the upper surface of each vertical beam outside the left and right rails, and the holding member is provided outside the fastening device and mounted between the left and right rails. One end of the pallet different from the placed pallet in the line width direction is placed on the upper surface of each vertical beam, and the other pallet is tracked by a holding member provided outside the left and right rails. It is the structure positioned in the width direction.

  In addition, the structure which positions a pallet with this holding member can be used also in each aspect of the pallet provided with the above-mentioned main-body part and a latching | locking part. In each of the above-described configurations of the pallet in which the main body portion enters below the upper surface of the vertical beam, a configuration using a holding member can be employed.

  In each of the above configurations, when a plurality of pallets are provided along the track direction, a configuration in which the plurality of pallets are connected by connecting means can be employed. As this connection means, the structure which clamp | tightens the volt | bolt inserted in the through-hole provided in the main-body part of each adjacent pallet with a nut can be considered, for example.

  According to the present invention, when the pallet is arranged, the pallet locking portion is placed on the upper surface of each vertical beam as long as the upper portion of the fastening device is not covered. Do not come. For this reason, it can be set as the planting installation structure with few troubles in the maintenance inspection of a track.
