Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a working deck of a tubing device used in an all-casing method.

[0002]

2. Description of the Related Art In a tubing apparatus, a casing is inserted and detached, a reinforced basket is inserted and connected, a tremy tube is inserted and detached, and a ready-mixed concrete is inserted. An approximately rectangular scaffold plate 3 having a casing tube insertion hole 2 is mounted thereon, and a work deck having a certain size for easy work is provided.

[0003]

However, this work deck requires a scaffold plate 3 in order to secure a sufficient space.
Are often formed in a shape protruding from one side of the tubing apparatus main body 1, and the protruding portion becomes a hindrance when construction is performed near the wall of an adjacent building.
As shown in FIG. 8, a scaffold plate 3 with one side notched is created and replaced. As shown in FIG. 8, when the scaffold plate 3 is of a split type, work is performed by removing one scaffold plate. Was. For this reason, in the former, the cost is increased and the replacement work is troublesome, and in the latter, the work space is restricted because the scaffold plate 3 is only on one side, and the work efficiency is affected.

Accordingly, an object of the present invention is to provide a working deck of a tubing device capable of easily performing a work of expanding and contracting a scaffold plate at the time of construction just beside a wall.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a working deck of a tubing apparatus in which a substantially rectangular scaffold plate having a casing tube insertion hole in the center is mounted on the tubing apparatus main body. , At least one side of the scaffold plate is formed so as not to protrude from one side of the tubing device main body, and a foot plate is detachably provided on one side of the scaffold plate. A handrail can be replaced between one side of the scaffold plate and an outer side of the footrest plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in FIGS. The same elements as those of the conventional example are denoted by the same reference numerals and described. In the tubing device 4, the elevating frame 5 and the chuck device support frame 6 that constitute the tubing device main body 1 and the base frame 7 that supports the tubing device main body 1 are formed to have substantially the same width in a substantially rectangular shape in plan view.

The base frame 7 has four thrust cylinders 8 for supporting the elevating frame 5 so as to be able to move up and down. The elevating frame 5 is a ring-shaped rotating frame having a guide post 9 and a casing tube insertion hole 2 formed therein. 10 and
A chuck cylinder (not shown) for raising and lowering the chuck device support frame 6;
Has a plurality of chuck members 11 suspended on a ring-shaped rotating frame having the casing tube insertion hole 2 formed therein.

The tubing device 4 lowers the chuck member 11 between the casing tube 12 inserted into the casing tube insertion hole 2 and the rotating frame 10,
While holding the casing tube 12 and rotating the rotary frame 10 with the hydraulic motor 13, the thrust cylinder 8
The elevating frame 5 is moved up and down by the expansion and contraction of the casing tube 12 to push and pull the casing tube 12.

The scaffold plate 3 is mounted on the upper surface of the chuck device support frame 6. The scaffold plate 3 is composed of four divided scaffold plates 31, 32, 33 and 34 having a casing tube insertion hole 2 in the center, and is mounted on one long side 6 a side of the chuck device support frame 6. Scaffolding board 3
1 and 32 are formed so that the sides 31a and 32a on the long side 6a side protrude from the long side 6a, and the scaffold plates 33 and 34 placed on the other long side 6b side are formed on the long side 6b side. Side 3
3a and 34a are formed in a shape that does not protrude from the long side 6b.

[0010] Sides 33a, 34 of the scaffold plates 33, 34
a is bent downward by 90 degrees, and the sides 33a, 34a
Are mounted with bolts 16. The footrests 15, 15 are formed to have substantially the same width as the widths of the side edges 31a, 32a of the scaffold plates 31, 32 projecting from the long side 6a.

The handrails 17 are provided on the outer peripheral sides of the scaffolding plates 31 and 32, and the handrails 17 and the ladders 18 are provided on the short sides of the scaffolding plates 33 and 34, respectively. Fifteen
A handrail 17 is also provided at the outer end of. Footboard 1
The handrails 17 of 5 and 15 are detachably inserted into a cylinder 19 fixed to the footrests 15 and 15.

As shown in FIGS. 4 and 5, the footrests 15, 15 can be removed from the scaffolds 33, 34 by removing the bolts 16 at the time of wall construction, in which case, as shown in FIGS. As shown in FIG. 6, a bracket 21 provided with a handrail insertion tube 20 is attached to a footrest plate mounting hole of the scaffold plates 33, 34 with bolts 16 to thereby remove the handrail 17 removed from the footrest plate 15. Are replaced with scaffold plates 33, 34.

Therefore, at the time of the wall work, the scaffolding plates 15 and 15 can be removed from the scaffolding plates 33 and 34 and the handrails 17 can be replaced without replacing the scaffolding plates or removing the scaffolding plates 33 and 34. In addition, a sufficient space for the work can be secured, and the tubing device 4 can be brought close to the edge of the wall, so that the work of expanding and contracting the scaffold plate 3 can be easily performed.

In the above embodiment, the foot rest 1
Although the description has been made on the case where the scaffolds 5 and 15 are attached and detached on one side of the scaffold plate 3, the present invention is not limited to this, and the scaffold plate 3 and the footrest plate 15 may be of an integral structure.

[0015]

As described above, in the working deck of the tubing device of the present invention, at least one side of the scaffold plate to be placed on the upper surface of the tubing device main body is formed so as not to protrude from one side of the tubing device main body. And, since the footboard is detachably provided on one side of the scaffold, at the time of wall construction, by removing the footboard from the scaffold, there will be no protrusion from the tubing device, and the tubing device will be at the very edge of the wall The scaffold plate can be easily moved. In addition, since handrails can be attached to one side of the scaffolding plate and the outer side of the footing plate, safety during construction can be ensured.
