Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a glove box, and more particularly to a method for constructing a glove box as a radioactive material treatment facility.

[0002]

2. Description of the Related Art In a radioactive material treatment facility, a glove box is arranged to protect the human body from the radiation source and to easily operate the apparatus. That is, as shown in FIG. 4, the radioactive substance treatment device 1 is provided with the shielding walls 2a to 2e,
The radiation source is enclosed by being surrounded by a plurality of acrylic panels 4 having a plurality of globe ports 3 to protect the worker m. Due to the problem of seismic resistance, this glove box has shielding walls 2a-2 as shown in FIGS.
A pedestal 5 for mounting the e and acrylic panels 4 and an internal pedestal 6 for mounting the radioactive substance treatment equipment 1 are provided.

The construction of such a glove box is usually carried out at a predetermined construction site by a pedestal 5 and an internal pedestal 6.
Is built and a predetermined device is attached to a predetermined internal frame 6.

[0004]

The construction method of the glove box as described above requires installation of various equipment, piping work and inspection work at a construction site that is narrow and has a bad working environment. Since such work requires precision because of the problem of safety of the device, the work requires a lot of time and labor, resulting in prolongation of glove box construction and cost increase.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and includes a step of manufacturing a plurality of unit internal mounts in a factory, and a predetermined device for each unit internal mount. It is intended to provide a method for constructing a glove box, which comprises the steps of installing and unitizing the units, transporting the unit internal gantry to the site, joining each unit internal gantry, and joining each device. is there.

According to the present invention, a predetermined device is attached to a unit internal rack inside a factory to manufacture a partial internal assembly, and the internal assembly is installed on the rack installed at a construction site. The internal assembly is equipped with a predetermined device by using a separate stand or the like, and is provided with pipes and wirings related to the device, and a partition wall if necessary. This unit internal mount is a frame, but it is also possible to put a plate on the outside of the mount to make it a box-shaped one if necessary.

[0007]

[Operation] According to the construction method of such a glove box, it is possible to install, pipe, and inspect the prescribed equipment on a single internal rack in a factory with a good working environment, and then transfer it to the construction site as a unit, Since the unit internal pedestals are joined to construct the internal pedestal and necessary equipment pipes are joined, the work becomes extremely simple and quick.

[0008]

EXAMPLE An example of the construction method of the glove box according to the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 shows a gantry built at a construction site. The gantry 10 is a frame body formed by a plurality of pillar members 11 and beam members 12, and the gantry 10 has can bodies 13a to 13e and acrylics. The panel 14 is attached and configured as a hermetically sealed structure, which is constructed by opening the ceiling of the glove box on site and inserting the assembled pedestal into the factory as an integrated body.

On the other hand, in the factory, as shown in FIG. 2, a plurality of so-called unit internal mounts 15a to 15b are manufactured by dividing the internal mount 14 at predetermined positions in advance. The unit internal mounts 15a to 15b are unit pillars 16a to 16c, respectively.
And unit beams 17a to 17e, and a supporting member 20 for mounting the beam 18 and the device 19 is arranged as necessary from the viewpoint of strength.

Predetermined devices 19 and pipes 21 are provided on the unit internal mounts 15a to 15d, respectively. Of course, in the installation of the device 19 and the work of the pipe 21, the inspection is performed thereafter. The unit mounts 15a to 15d are assembled in multiple stages as necessary, but it is necessary to join them vertically. There are various conceivable joining methods, for example, as shown in FIG.
As shown in A of FIG. 3, a plug-in type in which the lower pillar member 16 ′ is fitted to the upper pillar member 16 and B of FIG.
As shown in FIG. 3C, a method in which both of the upper and lower pillars 16 and 16 ′ of the lower pillar are hollowed and the fixing metal fittings 22 are interposed between the ends of both, and the method is shown in FIG. 3C. So pillar material 1
6'is provided with a metal fitting 16m, which enables the unit mount 15a.
The side beam member 17 may be supported. The size of the unit internal pedestal varies depending on the size of the glove box and the equipment to be installed. When the device 19 is installed on the unit internal frame as described above, the pipe 21 is provided as necessary.

In this way, the unit internal mounts 15a-15
When a predetermined device 19 is attached to d and unitized, it is transported to the site. And this unit internal mount 15a-
15b is lifted by a forklift or the like, is inserted into the inside from the front surface of the gantry 11 built on the site in advance, and is installed and joined to build the internal gantry 14. In addition, in the said Example, the individual can bodies 13a-1.
Although the method of constructing the glove box by providing the equipment 3e and inserting the equipments assembled in the factory into the equipment 3e has been described, the can body 13 may be one or several in some cases. It is preferable to determine the size of the can body 13 in consideration of its size and type.

[0012]

The method of constructing a glove box according to the present invention comprises the steps of constructing a gantry composed of a pillar and a beam at a construction site, a step of manufacturing a plurality of unit internal gantry in a factory, and each unit. The process of installing a predetermined device on the internal rack to make it a unit, and transporting each unit internal rack to the site,
The process includes the steps of joining the unit internal frames and joining the devices.

Therefore, according to the construction method of the glove box according to the present invention, the installation, piping, and inspection work of the equipment can be performed in a manufacturing factory with a good working environment, so that the working time can be greatly shortened. As a result, there is an effect that the construction period can be shortened and the cost can be reduced.
