Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a working deck of a tubing device used in an all-casing method.
[0002]
[Prior art]
In the tubing device, in order to perform operations such as insertion and removal of a casing, insertion and connection of a reinforcing steel basket, insertion and removal of a tremy tube, and insertion of ready-mixed concrete, a casing tube insertion hole 2 And a work deck having a certain size that facilitates work is provided on the substantially rectangular scaffold plate 3 having.
[0003]
[Problems to be solved by the invention]
However, in order to secure a sufficient space, the work deck often has a shape in which the scaffold plate 3 is formed to protrude from one side of the tubing device main body 1. In this case, the protruding portion becomes a hindrance. Therefore, as shown in FIG. 7, the scaffold plate 3 having one side notched is created and replaced, or the scaffold plate 3 is divided as shown in FIG. In the case of the type, the work was done by removing the scaffold plate on one side. 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.
[0004]
Therefore, an object of the present invention is to provide a working deck of a tubing device that can easily perform a work of expanding and contracting a scaffold plate when performing construction just beside a wall.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention relates to a working deck of a tubing device in which a substantially rectangular scaffold plate having a casing tube insertion hole in the center is mounted on a tubing device main body upper surface, wherein the tubing device is a tubing device. An elevating frame and a chuck device supporting frame constituting the main body and a base frame supporting the tubing device main body are formed to have substantially the same width of a substantially rectangular shape in plan view , and at least one side of the substantially rectangular scaffold plate is formed by the tubing. Forming a shape that does not protrude from one side of the device main body, and a footrest that protrudes from one side of the tubing device main body when attached to one side of the substantially rectangular scaffold plate, It is characterized by providing a possible desorption on one side. In addition, one side of the scaffold plate and an outer side of the footrest plate can be replaced with a handrail.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described based on the embodiment shown in FIGS. The same elements as those in the conventional example will be described with the same reference numerals. In the tubing device 4, the elevating frame 5 and the chuck device support frame 6, which constitute the tubing device main body 1, and the base frame 7, which supports the tubing device main body 1, are formed to have substantially the same width in a substantially rectangular shape in plan view.
[0007]
The base frame 7 includes four thrust cylinders 8 that support the elevating frame 5 so as to be able to elevate and lower. The elevating frame 5 includes a guide post 9, a ring-shaped rotating frame 10 in which the casing tube insertion hole 2 is formed, and A chuck cylinder (not shown) for raising and lowering the chuck device support frame 6; the chuck device support frame 6 includes a plurality of chuck members 11 suspended by a ring-shaped rotary frame having the casing tube insertion hole 2 formed therein. have.
[0008]
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, grips the casing tube 12, and rotates the rotating frame 10 with the hydraulic motor 13. The elevating frame 5 is moved up and down by the expansion and contraction of the thrust cylinder 8 to push and pull the casing tube 12.
[0009]
The scaffold plate 3 is placed 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. The scaffold plates 31 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 connected to the long side 6b. The side edges 33a and 34a are formed in a shape that does not protrude from the long side 6b.
[0010]
The sides 33a, 34a of the scaffold plates 33, 34 are bent downward by 90 degrees, and the foot plates 15, 15 are attached to the sides 33a, 34a with bolts 16. The footrests 15, 15 are formed so that the side edges 31a, 32a of the scaffolding plates 31, 32 are substantially the same width as the widths of the scaffolding plates 31, 32 projecting from the long side 6a . As shown in FIGS. , the sides 33a of 34, that protrudes from the longer side 6b when mounted on 34a.
[0011]
Handrails 17 are provided on the scaffold plates 31 and 32 on the outer peripheral side, and handrails 17 and ladders 18 are provided on the short sides of the scaffold plates 33 and 34. A handrail 17 is also provided at the end. The handrails 17 of the footrests 15, 15 are removably inserted into a cylinder 19 fixed to the footrests 15, 15.
[0012]
As shown in FIGS. 4 and 5, the footrests 15, 15 can be detached from the scaffolds 33, 34 by removing bolts 16 at the time of wall construction, and in this case, the scaffolds As shown in FIG. 6, a bracket 21 provided with a handrail insertion tube 20 is attached to the footrest plate mounting holes 33, 34 with bolts 16 so that the handrail 17 removed from the footrest plate 15 can be attached to the scaffold plate. Replace with 33,34.
[0013]
Therefore, at the time of the work near the wall, the scaffolding plates 15 and 15 are removed from the scaffolding plates 33 and 34 and the handrails 17 are replaced without replacing the scaffolding plates or removing the scaffolding plates 33 and 34, thereby making the work easier. A sufficient space 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.
[0014]
In the above-described embodiment, the description has been given of the case where the footrests 15 and 15 are attached to and detached from one side of the scaffolding plate 3; however, the present invention is not limited to this. good.
[0015]
【The invention's effect】
As described above, the working deck of the tubing device of the present invention is formed such that at least one side of the scaffold plate placed on the upper surface of the tubing device main body does not protrude from one side of the tubing device main body. Since the footboard is detachably provided on one side, when the wall is under construction, by removing the footboard from the scaffold, there is no protrusion from the tubing device, and the tubing device can be brought to the very edge of the wall, The work of expanding and contracting the scaffold can be easily performed. Also, since handrails can be attached to one side of the scaffolding plate and the outer side of the footrest, safety during construction can be ensured.
