In order to achieve this object, one aspect of the present invention provides a damper 40 on the duct 10 in the method of: marking the perforated portion 10a at one point of the duct 10, and the perforated portion ( Installing the booth 20 around 10a); Importing tools and materials into the booth 20 and cutting the marked perforations 10a; And installing a branch 30 and a damper 40 in the perforation part 10a and finishing the blinds 50 on the damper 40.

At this time, the booth 20 is caulking and clamping to prevent leakage and static pressure loss, and has a transparent monitoring window and the entrance 25 on one surface.

In addition, another aspect of the present invention provides a method of replacing or removing the damper 40 on the duct 10: by installing the booth 20 at one point of the duct 10 and inserting the tool into the booth 20. Importing the material; Installing a blind (50) between the duct (10) and the damper (40); And removing the damper 40 and leaving the blind 50 in accordance with the construction details, or installing the new damper 40 'and removing the blind 50.

In addition, another aspect of the present invention, a method for installing a new duct 10 on the duct (10): marking the perforations (10a) of the duct (10) and cut in diagonal lines; Closing the perforated portion 10a with a plurality of blinds 50 along the cut portion while cutting the perforated portion 10a; Installing a branch (30) on the perforation (10a) and simultaneously removing the blind (50); And removing the blind 50 'on the branch 30 and installing the new duct 10 at the same time.

In this case, the perforation part 10a of the duct 10 may be installed with a post 60 in the vicinity to be prevented from falling and connected to the binding port 70.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1A-1C are conceptual diagrams illustrating in sequence how to build a damper 40 on a duct 10 in accordance with one aspect of the present invention.

First, the perforated part 10a is marked at one point of the duct 10, and the booth 20 is installed around the perforated part 10a. The booth 20 is sized in consideration of the workable space and reinforces the slope so that deformation does not occur. The duct 10 having a separate casing on the outer surface removes the tin and insulation of the target site required before installation of the booth 20.

At this time, the booth 20 is caulking and clamping to prevent leakage and static pressure loss, and has a transparent monitoring window and an entrance 25 on one surface. Caulking and clamping is a work method that is easy to assemble and disassemble between the structure consisting of a plate, such as the duct 10 and the booth 20. In places where the temperature of the duct 10 is not high, an adhesive tape may be attached together with the caulking. The doorway 25 is sized to allow an operator, materials, tools, etc. to enter and exit for maintenance work and inspection. The monitoring window can be installed in a material such as transparent acrylic, so that the state of the duct 10 can be inspected without opening the entrance 25.

Of course, the doorway 25 and the monitoring window may be installed on the horizontal plane or the vertical plane of the booth 20 according to the situation of the site. In the situation where the booth 20 is installed on the side or bottom of the duct 10, it is particularly necessary to reinforce the booth 20 so that its own strength and the bond strength with the duct 10 do not decrease.

In the next step, the tool and the material are brought into the booth 20 and the marked punched part 10a is cut. When cutting the perforations 10a, tools such as a hammer, electric scissors, tin scissors, tin knife and the like are used.

Next, the branch 30 and the damper 40 are installed in the perforated part 10a and finished with the blinds 50 on the damper 40. Branch 30 has a flange protruding outward to facilitate coupling to the duct 10 with pieces and impact. Damper 40 is integrally coupled to branch 30 by means of caulking and clamping. The blind 50 is installed at the upper end of the damper 40, and the blind 50 may be removed as necessary. The blind 50 serves as a stopper to block the flow of the blind, so that the blind 50 may be removed. After is installed, the booth 20 is removed and when connecting a new duct to the installed branch 30 and the damper 40, after installing a new duct by the method described below, remove the blind 50 and the damper 40 and Connect a new duct.

2A through 2C are conceptual views illustrating a method of sequentially replacing or removing the damper 40 on the duct 10 according to another aspect of the present invention.

First, a step of installing the booth 20 at one point of the duct 10 and bringing in tools and materials into the booth 20 is performed. The installation method of the booth 20 is the same as that of FIGS. 1A to 1C described above. The booth 20 is installed so as to fully cover the damper 40 to be replaced or removed.

Next, the blind 50 is installed between the duct 10 and the damper 40. The connection between the duct 10 and the damper 40 is disassembled for the installation of the blind 50. When removing the damper 40, the blind 50 is installed near the source of the polluting gas so that the gas does not leak.

Next, according to the construction details, the damper 40 is removed and the blind 50 is left as it is, or a new damper 40 'is installed and the blind 50 is removed. When the damper 40 needs to be removed, the blind 50 is left as it is to prevent the leakage of contaminated gas. When replacing with a new damper (40 ') is inserted into the damper (40') between the duct 10, the binding, and the removal of the blind 50 is carried out at the appropriate time after approval.

3A to 3D are conceptual views sequentially illustrating a method of installing a new duct (not shown) on the duct 10 according to another aspect of the present invention.

First, marking the perforated part 10a of the existing duct 10 and proceeding to cut in a diagonal line, and then the perforated part 10a with a plurality of blinds 50 along the cutout while cutting the perforated part 10a. ). Simultaneously with the incision, the blind 50 must be pushed in to prevent leakage into the incision. Blocking the perforations 10a while overlapping several blinds 50 is to minimize the leakage.

In the next step, the blind 50 is removed while the branch 30 is installed on the perforated portion 10a. When the damper 40 or the new duct is installed, the branch 30 that serves as a branching pipe is first made. While pushing the branch 30 slightly from one side, the blind 50 is removed little by little. When the branch 30 is completely in place, the duct 10 is fixed with a piece or impact and then caulked.

In the next step, the blind 50 'on the branch 30 is removed and a new duct (not shown) is installed. At this time, the blind duct 50 'is removed little by little while pushing the new duct little by little. The same applies to the case where the damper 40 is provided between the newly formed duct and the branch 30.

Unlike the booth 20, unlike the method of FIG. 1 and FIG. 2, such a method shortens working time, but is preferably limited to a specific exhaust because it is easy to be exposed to an environment in which gas leaks.

4 is a conceptual diagram schematically illustrating a modification of FIGS. 3B and 3C.

The perforation part 10a of the above-described duct 10 may be installed with a post 60 in the vicinity so as to prevent a drop, and connected to the binding hole 70. When the size of the perforation part 10a is large or heavy, and sagging is likely to occur, it is preferable to support it using the post 60. The binding port 70 may be a piece or impact, although the adsorber using vacuum pressure is good.

If the beam jigsaw is used to cut the perforated portion 10a, a hole is formed on the cut line so that the jigsaw blade enters the perforated portion 10a. This system is limited to a specific exhaust which does not cause a fire.

According to the present invention, the blinds 50 may be appropriately used as a whole to repair the duct 10 in whole or in part, and the stability of the line against static pressure loss may be secured, thus not affecting the production of products such as semiconductors. This is limited to situations in which production should not be interrupted because of manpower and costs compared to the normal method of repairing ducts, and it is not necessary to use these methods during production facilities.

On the other hand, in the case of removing the duct 10 or the damper 40 and closing the pipe, it is preferable to further install a sealing member such as rubber packing in addition to the blind 50 to enhance the airtightness.

According to the above configuration and operation, the present invention has the effect of minimizing the loss and inconvenience caused by production and sales by performing operations such as duct replacement, removal and repair without interrupting the supply and exhaust in the facility in use. .

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
