[Industrial field of application] A method is adopted in which a track is installed using a space on an existing pile and a material such as a steel pile is transported by a transportation means that runs on the track. The invention is
The present invention relates to a rail support for a rail on a pile used for transporting materials in the above method.

[0002]

2. Description of the Related Art In order to construct a retaining wall or the like with piles, it is necessary to constantly supply piles and materials to the pile construction site. Therefore, conventionally, the material has been transported to the vicinity of the pile press-fitting / pulling machine by a transporting means such as a truck or a crane. However, with this method, the construction site is narrow, in the river, under the bridge,
Alternatively, there is a drawback that the transportation means cannot be used in a place where the scaffolding is poor.

Therefore, a space is installed on the existing piles, a track is installed at the upper end of the pile row, and construction materials and the like are transported by a transporting means that runs on the track. In order to install this track, a pair of flat rail pedestals were opposed to each other upright at the upper end of the existing pile row, and the piles were clamped to fix the rail pedestals on the existing piles (actual Kaihei 3 -12901 publication).

[0004]

However, in the above-mentioned rail pedestal, since the rail pedestal is formed in a flat plate shape and only one fitting groove into which the upper end of the pile is fitted is provided, Even if it is fixed to the upper end of the pile, it is not stable and falls in the rail laying direction (pile row direction), so it is necessary to firmly fix the mounting position of the rail pedestal to the pile with another fixing means. There was a problem. The invention is
By simply mounting the rail support on the upper end of the existing pile row,
It is an object of the present invention to provide a rail support for a rail for pile transportation that can be easily and reliably fixed.

[0005]

The rail support for the pile conveying track according to the present invention has rail support portions arranged facing each other on the upper surface, and
At the bottom of the upper rail receiving part, which has hanging parts on both sides of the surface,
A pair of legs with a fitting groove that fits into an existing pile should be
A special feature is that the lower rail receiving part, which is fixed with a gap, is installed.
In addition, the lower rail receiving portion is replaced with the upper rail receiving portion.
It is characterized by being attached rotatably to.

[0006]

[Operation] The rail support member is fixed on the pile by inserting the fitting groove of the leg portion into the web portion or the flange portion of the existing pile. Then, the rail is placed on the upper surface of the upper rail receiving portion. At this time, if the leg portions are directly fixed to the lower surface of the upper rail receiving portion, the leg portions can be stably fixed to the web portion of the existing pile with a simple structure. Also, when the legs are formed facing each other at a predetermined interval, they are arranged so as to straddle the grips of the adjacent piles of the existing piles, and the flanges of the left and right piles are fitted in the fitting grooves of the respective legs. Since the part can be fitted and fixed on the existing pile, it can be fixed more stably. Further, since the upper rail receiving portion and the lower rail receiving portion can be pivotally adjusted, the rail can be easily installed along the curve even when the rail is laid on the existing pile that is laid in a curved shape.

The lower rail receiving portion 6 has a pair of leg portions 5 on its lower surface.
Are fixed to face each other at a predetermined interval, and two fitting grooves 9 opened downward are formed at each of the leg portions 5 at a predetermined interval. The leg portion 5 is provided with a supporting portion 2 which is a reinforcing member between the fitting grooves 9, and the upper rail receiving portion 8 and the lower rail receiving portion 6 are rotatably attached by screws 7.

Further, as in the second embodiment shown in FIG.
The pair of legs 5 of the first embodiment may be directly fixed to the upper rail receiving portion 8 by welding. At this time, the lower rail receiving portion 6 is not necessary. The rails shown in FIGS. 6 and 7 are rails.
This is an example of one embodiment of the support, and the upper rail receiving portion 8 is formed by a substantially rectangular flat plate made of metal, and the rail supporting portions 1 are provided at both ends of the upper surface in the longitudinal direction. The arm portion 3 is provided orthogonally to the longitudinal direction. Then, the hanging portions 4 are formed on the lower surfaces of both side portions in parallel to the longitudinal direction, and one leg portion 5 provided with a fitting groove 9 opened downward is directly attached to the lower surface of the upper rail receiving portion 8. With this configuration, the rail support 12 can be fixed to the web portion 18 of the existing pile 13. This leg 5
The rail support 12 can be more stably fixed to the web portion 18 by providing two or more and providing them at appropriate intervals.

In the example of one embodiment shown in FIGS. 8 and 9, the leg portion 5 having the fitting groove 9 opened downward is formed on the lower surface of the lower rail receiving portion 6 having the arc-shaped elongated hole 19. Then, the upper rail receiving portion 8 and the lower rail receiving portion 6 are rotatably coupled by inserting the screw 20 into the elongated hole 19.
By this connection, even when the rail is laid at a location where the existing pile row is laid in a curve, it can be easily attached along the curve.

Next, the usage of this embodiment having the above-mentioned structure will be described. In the first embodiment shown in FIG. 2, a grip portion 17, which is a joint portion of the existing pile 13, is arranged so as to straddle between a pair of leg portions 5 that are formed to face each other at a predetermined interval, and The flange portion 10 of the existing pile is fitted into the one fitting groove 9 provided in the leg portion 5, and the rail support 12 is fixed onto the existing pile. At this time, since the lower end of the hanging part 4 contacts the upper end of the existing pile 13, it is stably fixed.

As shown in FIG. 4, the rails are placed on the rail supports 12 and 12 arranged as described above. In this embodiment, the same U-shaped steel sheet pile as that of the existing pile 13 is used as the rail 14, and both flange portions of the U-shaped steel sheet pile are supported by the rail supporting portion 1 of the upper rail receiving portion 8 and the rail 1
Placement of 4 is completed. When the material is conveyed along the rail thus placed, for example, a conveying device 16 having wheels 15 is used as shown by the phantom line in FIG. The second embodiment shown in FIG. 5 is also used in the same manner as above.

In the embodiment of the rail support shown in FIG. 6, the web portion 18 of the existing pile 13 is fitted into the fitting groove 9 formed in the leg portion 5.
