Description

[Detailed Description of the Invention] The present invention relates to a pile holding device, and particularly to a holding device suitable for use when stacking sheet piles used in foundation construction and seawall construction after use.

Conventionally, sheet piles have been used for construction work, then pulled out and reused. However, since these sheet piles are generally 7 m or more in length and even reach 20 m in length, they require a large area for storage. Therefore, sheet piles after use are usually stacked and stored.

This lamination work is carried out by hoisting the sheet pile with a rope or the like, lowering it so that one end matches the end of the already laminated sheet pile, and then gradually lowering it and stacking. However, the suspension ropes had to be removed before the sheet piles could be completely laminated. This removal work involves placing a sleeper on top of the already stacked sheet piles, lowering the sheet pile suspended on the sleeper, removing the rope, and then pulling out the sleeper with a hammer or the like. work was being carried out.

Although recent mechanization has made the removal, lifting, and lowering of sheet piles more efficient, the work of removing sleepers after removing ropes during stacking is still done using primitive methods. However, it has not been possible to improve the efficiency or save labor of the entire work.

Therefore, the present invention was devised in view of the conventional problems mentioned above, and its purpose is to improve work efficiency and save labor by providing an easily removable holding device in place of sleepers. be.

In order to achieve the above object, the present invention divides the standing plate interposed between the lower pile and the upper pile stacked on the pile into two at approximately the midpoint in the height direction, and rotates with a hinge. In addition to being able to move freely,
This upright plate is characterized by being provided with a regulating plate for regulating rotation in one direction and a locking portion for locking a tensioning tool for rotation.

Embodiments of the present invention will be described below with reference to illustrated examples.

In the figure, 10 is a sheet pile that has already been laminated, and above this is located a sheet pile 11 that will be laminated next. This sheet pile 11
One side (left side in FIG. 2) is placed on the sheet pile 10 and then suspended by a rope (not shown).

An upright plate 20 is interposed between both sheet piles 10 and 11. This standing plate 20 is divided into a lower standing plate 21 and an upper standing plate 22 approximately at the center, and is rotatably formed on a hinge 23 provided on the back surface.

The lower upright plate 21 is provided with support plates 24 near both sides of the lower back surface to prevent the upright plate 20 from falling toward the back. In addition, at approximately the center of the lower surface of the lower standing plate 21, there is a notch 25 that straddles the bead when used for the sheet pile 10 provided with a bead.
is missing, and furthermore, a punched portion 26 is provided in the center for weight reduction.

A gripping rod 27 is provided to protrude from the upper standing plate 22 in the front direction. Further, the upper part of the upper standing plate 22 is formed to be narrow so that the upper standing plate 22 is located between the supporting plates 24 of the lower standing plate 21 when rotated about the hinge 23. Further, a locking plate 29 having a locking hole 28 is fixed to the lower surface of the upper standing plate 22. The locking hole 28 is for locking a rope 30 as a tensioning tool for rotating the standing plate 20. Although the locking plate 29 is fixed to the upper standing plate 22, it is extended to the surface side of the lower standing plate 22, so that the upper standing plate 22 and the lower standing plate 21 are in a straight line. It is formed so that it sometimes collides with the surface of the lower standing plate 21, and also functions as a regulating plate that restricts the rotation of the standing plate 20 in one direction.

Next, the use of the present invention will be explained based on FIGS. 2 and 3.

First, the sheet pile 11 to be further laminated on top of the already laminated sheet pile 10 is lifted up, one end is aligned with the end of the sheet pile 10, and then it is gradually lowered. During this descent, when the distance between the other end of the sheet pile 11 and the other end of the sheet pile 10 already stacked is slightly longer than the height of the standing board 20, the descent is temporarily stopped, and the standing board Interpose 20. After that, lower it again and sheet pile 1
1 at the upper end of the upper standing plate 22, remove the hanging rope (not shown), and then insert the locking hole 2.
8, pull the rope 30, pull out the device from the upper and lower sheet piles 10, 11,
The sheet piles 10 and 11 are laminated.

In addition, a sheet pile 11 is installed at the upper end of the upper standing plate 22.
In order to prevent an accident in which the upright plate 20 shakes and rotates when lowering, the gripping rod 27 can be pushed downward to prevent rotation about the hinge 23.

Furthermore, when the device is extracted, the gripping rod 27 may collide with the edge of the sheet pile 11, but this collision acts to push the device out from between the sheet piles 10 and 11, which reduces the extraction efficiency. will improve. Therefore, outside the gripping rod 27,
It is also possible to provide an impact rod (not shown) for the purpose of impacting the edge of the sheet pile 11 to improve extraction efficiency.

In addition, in the embodiment, the lower standing plate 21 and the upper standing plate 22 are butted against each other, and a hinge 23 is provided on the back side of the lower standing plate 21 and the upper standing plate 22.
, the load on the sheet pile 11 acts to rotate the upright plate 20 to the front side, but the rotation to the front side is restricted by the locking plate 29. Therefore, when formed as in the example, lateral vibration,
Or, there is no accident such as sudden rotation of the standing plate 20 due to slight shaking in the longitudinal direction.

Furthermore, in the embodiment, the locking plate 29 was formed to have two functions as a restriction plate and a locking part, but it can be used as a restriction plate that restricts rotation in one direction and a locking plate that locks a tensioning tool. It can also be formed separately from a locking portion.

In addition, in the illustrated example, the sheet piles 10, 11
Although an example has been shown in which the sheet piles 10 and 11 are stacked in a substantially mountain shape, it is also possible to stack the same sheet piles 10 and 11 in a substantially groove shape.

In the above description, sheet piles have been used as an example of piles, but in addition to this, for example, laminated tube piles can also be used.

As explained above, the present invention is interposed between piles to be stacked and can significantly improve efficiency and save labor when performing pile stacking work.
