Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a pile supporting device for temporarily stopping the lower pile at a predetermined position when connecting the piles.

[0002]

[Prior art]

 Conventionally, when piling up piles, a ring-shaped wire for locking was tied to the lower pile, and the wire was locked to a locking tool placed on the ground to support and stand the lower pile. . Subsequently, the lower pile was removed from the pile driver, the upper pile was grasped by the pile driver, and the lower pile and the upper pile were connected.

Then, after the connection work is completed, the connected pile is once lifted to release the lock between the wire and the locking tool, and then the connected pile is lowered to be buried.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional technique, when the pile connection work is completed and the support of the piles is removed, the piles that have been once connected have to be lifted, and the work becomes complicated.

[0005]

[Means for Solving the Problems]

 However, the present invention solves the above-mentioned problems because the wire locking portion is provided on the outer cylinder that can be raised and lowered.

That is, according to this invention, an inner cylinder is erected and fixed on a base which can be placed around the buried position of the pile and which has an insertion portion of the pile, and the outer cylinder is attached to the inner cylinder so as to be able to move up and down. The outer cylinder is provided with a wire support portion, the inner cylinder and the outer wall are provided with locking portions, and the outer cylinder is provided with a locking tool that can be detachably locked to the locking portion. It is a support device for piles.

Further, in the above-mentioned locking tool, an upper end portion of a vertically-arranged locking rod is rotatably axially fixed to an outer wall of an upper portion of the outer cylinder, and a lower end portion of the locking rod is connected to the outer cylinder. It is also possible to arrange it so as to be located below the lower edge of the inner cylinder and to form a disengageable locking claw at the locking portion of the inner cylinder. Further, a stopper that restricts the rotation of the locking rod in the locked state can be removably installed on the outer wall of the outer cylinder. Further, the base in the above may be configured by arranging two steel materials in parallel with sandwiching a pile hole, and mounting and mounting a substrate on one side of both steel materials.

[0008]

[Action]

 Since the outer cylinder can slide up and down along the inner cylinder, the wire supporting portion provided on the outer cylinder can also move up and down while supporting the wire of the pile. The locking tool can regulate the sliding of the outer cylinder.

[0009]

Embodiment 1 An embodiment of the present invention will be described with reference to the drawings.

The same square steel pipes 2 and 2 are erected on the central portion 1a and one end portion 1b of two square steel pipes 1 and 1 arranged in parallel at a predetermined interval (wider than the pile diameter), and are integrally welded and connected. A substrate 3 made of a steel plate is placed on the upper surfaces of the square steel pipes 2, 2 and the inner upper faces of the square steel pipes 1, 1 and integrally welded to each other to form a substantially U-shaped base 4 (FIG. 5 (a) (b)). In the above description, the space between the other sides 1c and 1c of the square steel pipes 1 and 1 is defined as an opening portion (pile insertion portion) 5.

The inner cylinder 6 is erected and fixed on the substrate 3 of the base 4. A lid 6a is fixed to the top surface of the inner cylinder 6, and bearings 7, 7 are projected on the lid 6a. A shaft 14 of a base end portion 11 of a locking rod (locking tool) 10 is rotatably installed on the bearings 7, 7. A locking claw 12 facing the inner cylinder 6 side is formed at the tip of the locking rod 10.

An outer cylinder 8 is installed on the outer side of the inner cylinder 6 so as to be able to move up and down. A wire support portion 9 composed of a U-shaped projection is fixed to the outer wall of the outer cylinder 8 on the side of the opening 5. Further, a locking projection 15 capable of locking the locking claw 12 of the locking rod 10 is provided on the upper portion of the outer wall of the outer cylinder 8. The locking projection 15 is locked by the locking claw 12 when the outer cylinder 8 is located at the uppermost position, and the outer cylinder 8 is supported at a predetermined position.

Further, a stopper 13 for restricting the rotation of the locking rod 10 in a state of being locked by the locking projection 15 is detachably fitted into the notches in the upper portions of the bearings 7, 7. The supporting device 16 is configured as described above (FIGS. 1 and 2). Reference numeral 22 in the figure denotes a grip rod for lifting the outer cylinder.

Next, the use of this invention based on the above embodiment will be described.

The base 4 of the supporting device 16 is placed on the ground 21. At this time, the base 4 is arranged such that the pile holes (pile burying positions) 17 are located in the openings 5 and the wire support portions 9 are close to the pile holes 17. The outer cylinder 8 is raised above the inner cylinder 6, the locking claws 12 of the locking rods 10 are locked to the locking projections 15 of the outer cylinder 8, and the stoppers 13 are attached (FIG. 3). In this state, the outer cylinder 8 is located above the inner cylinder 6, and the wire locking portion 9 of the outer cylinder 8 faces the pile hole 17 side.

The wire 19 fixed to the first pile 18 is locked to the wire locking portion 9. Then, the first pile 18 and the pile driver (not shown) are disconnected. At this time, since the first pile 18 is supported by the support device 15 via the wire 19, the first pile 18 does not fall by its own weight (FIG. 3).

Next, the second pile (not shown) 20 is connected to the pile driver, and the second pile is connected to the first pile 18. Then, the stopper 13 is removed, the locking rod 10 is rotated, and the locking claw 12 of the locking rod 10 and the locking projection 15 are unlocked (FIG. 3, chain line 10). Falls by its own weight, and the wire 19 of the first pile 18 is disengaged from the wire support portion 9 (Fig. 4). Then, the connected first pile 18 and second pile are sunk. Furthermore, when connecting the third pile, wire is similarly attached to the upper end of the second pile (not shown).

Although the inner cylinder 6 and the outer cylinder 8 are both cylindrical in the above-described embodiment, they may be rectangular cylinders as long as the inner cylinder 6 and the outer cylinder 8 are vertically slidable.

Further, in the above-described embodiment, the wire support portion 9 is a U-shaped projection, but it may be configured by an L-shaped projection or the like as long as it can support the wire 19 of the pile (none of which is shown).

Further, in the above-mentioned embodiment, the steel plate is used as the substrate 3, but the substrate 3 may be in the form of a steel net or a lattice of steel rods (not shown).

Further, although the base 4 in the above-described embodiment is composed of the square steel pipes 1 and 2, it may be composed of a type steel such as an H-shaped steel, and the pile is vertically provided adjacent to the inner cylinder 6. Other structures such as a plane square and a circle having the opening 5 in the center can be used as long as the opening can be formed (not shown).

Further, if the base 4 has a structure having an opening 5, it is possible to stably support the piles. Therefore, it is preferable that the base 4 has an opening if it can be installed around the pile holes 17. It is also possible to use a structure that does not include, for example, a flat rectangular shape or a flat circular shape (not shown).

Further, the locking tool is composed of the locking rod 10 with the locking claw 12 and is structured to be engaged with and disengaged from the locking projection 15 of the outer cylinder 8. However, the inner cylinder 6 and the outer cylinder 8 are Other structures can be used (not shown) as long as they can be engaged and disengaged and the lifting and lowering of the outer cylinder 8 can be restricted.

[0024]

[Effect of device]

 An outer cylinder with a wire support can be attached to the inner cylinder so that it can be moved up and down, and lifting can be restricted by a locking tool, so the wire attached to the pile can be supported by the wire support and the pile can be held in place. At the held position, it has the effect of releasing the holding of the wire. Therefore, there is an effect that the staking work while connecting the piles can be made efficient.
