Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a workbench used for press-fitting / pulling out a pile by a pile press-in / pull-out machine at a coast, a river, a mud marsh or the like.

(Prior Art) When press-fitting a pile on water, it is necessary to provide a temporary scaffold near the pile press-in / pull-out machine. In addition, when there is an obstacle at the upper part of the work place, it is necessary to connect the piles. Scaffolding has become more important because welding or bolt joining work has increased to connect the piles.

In the conventional work table, as shown in FIG. 8, a bracket 16 is attached to an existing pile P standing on the river bed 20, and a scaffold board 9 is laid on it. Alternatively, as shown in FIG. 9, a single pipe Q was erected in water and a scaffolding plate 9 was placed on it to provide a workbench. Further, since these scaffolds are fixed, ships may be used when operating machines.

(Problems to be solved by the invention) When the bracket 16 is attached to the existing pile P and the scaffolding plate 9 is hung, a large amount of manpower and time are required, and the forward extension of the scaffolding plate cannot be taken to a large extent. There was a limit to. Moreover, when constructing a single pipe scaffold, it took more manpower and time because the single pipe was embedded up to the riverbed, the frame was built with the work boat, and the scaffolding board was hung.

Moreover, these scaffolds are not always suitable for the press-fitting work that is progressing, because once they are constructed, changes and movements are troublesome.

(Means for Solving the Problems) In order to solve the above problems, the present invention configures a locking portion on both sides of a pile press-in / pull-out machine, and configures a scaffolding plate having an engaging body such as a bracket at an end thereof. The engaging member is detachably attached to the locking portion. Further, the present invention is characterized in that an engaging body is provided upright on the scaffolding plate, and the engaging body is detachably fixed to the lifting cylinder of the pile press-fitting / pulling machine.

(Operation) A scaffold plate is attached to the pile press-in / pull-out machine by engaging the upper ends of the engaging bodies with the locking portions on both sides of the saddle of the pile press-in / pull-out machine, and work is performed on this scaffold plate. Alternatively, a scaffold plate is attached to the pile press-in / extractor by fixing an annular support to the lifting mechanism of the pile press-in / extractor.

This workbench moves with the pile press-in / pull-out machine during work, and can be easily removed when it is no longer needed after work.

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

FIG. 1 is a plan view of the first embodiment, FIG. 2 is a front view of the same, and FIG.
The figure is an enlarged side view of the bracket.

In the first embodiment of the workbench 1 of the present invention, the hook rods 5 are fixed to both sides of the saddle 3 of the pile press-fitting / pulling machine 2 as shown in FIG. A bracket 6 having a scaffolding plate 9 fixed thereto is hooked on the hook rod 5.

The hook bar 5 is attached to the saddle 3 with a gap in which the bracket 6 can be hooked, as shown in the drawing.

As shown in FIG. 3, the bracket 6 has a hook-shaped engaging portion 7 at its tip, a hole 8 for screwing a bolt B in its middle portion, and a scaffolding plate 9 attached to its lower end. A method such as welding is used to attach the scaffolding plate 9.

The scaffolding plate 9 uses a checker panel, expanded metal, or the like, and is assembled around the pile press-fitting / pulling-out machine 2 so that the planar shape is a substantially U-shape. The tongue pieces 9a and the connecting rod 9b formed on the scaffolding plate 9 are used to connect the scaffolding plates 9 to each other.

Further, in this embodiment, in order to enhance safety, the reinforcing material 10
The scaffolding plate 9 and the bracket 6 are connected with each other, and a handrail 15 is formed on the upper periphery of the scaffolding plate 9.

A method of using this embodiment will be described based on the above configuration.

The pile press-fitting / extracting machine 2 is installed on the upper end of the pile P press-fitted in water. The engaging portion 7 of the bracket 6 is hooked on the hook rod 5 of the pile press-in / pull-out machine 2 to attach the scaffold plate 9 to the pile press-in / pull-out machine 2. After mounting, the bolt B is screwed into the hole 8 of the bracket 6 and securely fixed to the saddle 3. Then, various works are performed on the scaffolding board 10.

As described above, according to the workbench 1 of this embodiment, the workbench can be quickly assembled by a small number of humans. Furthermore, the front projection of the scaffolding plate 9 can be made large. Working table 1
Since it moves with the pile press-fitting / pulling machine 2, it is suitable for press-fitting / pulling-out work of piles.

In this embodiment, the low-floor pile press-fitting / pulling machine is used, but the pile press-fitting / pulling machine to be used is not limited to this, and a normal pile press-fitting / pulling machine is also possible.

The second embodiment is a workbench 11 used when press-fitting a pile into a corner. In this embodiment, as shown in FIG.
Are connected to each other in a substantially U shape, and the columns 1 are attached to the side portions of the scaffolding plates 9 on both sides.
2 is erected, and an annular support 13 that can be fixed to the lifting cylinder 4 of the pile press-fitting / pulling machine 2 is attached to the column 12.
The support 13 has a connecting portion 14 and can be detachably fixed to the lifting cylinder 4 of the pile press-fitting / extracting machine 2 by a bolt B.

The method of use and the effect of this embodiment based on the above-mentioned structure are substantially the same as those of the first embodiment, but this embodiment is capable of press-fitting the corners of the pile P while the workbench 11 is mounted on the pile press-fitting / extracting machine 2. Have an effect.

That is, in the first embodiment, when the pile press-fitting / extracting machine 2 bends a corner, when the base 2a is rotated, the chuck C is moved to the workbench 1.
It was not possible to press-in the corners of the pile P due to the contact with. In this embodiment, the lifting cylinder 4 of the pile press-fitting / extracting machine 2 is fixed by the support 13 to prevent the chuck C from coming into contact with the workbench 11 when the base 2a is rotated.

(Effect of the Invention) As described above, according to the present invention, it is possible to set the optimum work floor area in the press-fitting / pulling-out work of the pile. In particular, even if the pile press-in / pull-out work progresses, the workbench of the present invention moves with the pile press-in / pull-out machine, so that the required work floor area can be always secured. In addition, the scaffolding plate can be easily attached and detached, and labor and time can be saved.
