Description

[Detailed Description of the Invention] This invention relates to an improvement in the construction method of a seal for edematous root storage. In a conventional floating roof storage tank, urethane foam is used to seal the gap between the floating roof and the storage tank side plate. It is known that the delta e-seal that uses the urethane foam has disadvantages such as poor installation workability of the urethane foam and the 7-ohm urethane taking various shapes during installation. One method is to insert a soft breathable 7 ohm material tube into a bag made of a flexible thin sheet, and then remove the air inside the bag and the 7 ohm material. After compressing, one bag is sealed, and the sealing member is inserted through the upper opening of the Suka7 band provided between the outer periphery of the floating roof and the storage tank side plate, and the back cover is opened and expanded to airtight the area between the floating roof and the side plate. For example, a method of applying a seal for a floating roof storage tank, which is characterized by fixing the upper end of the ski 7 pan to the outer periphery of the floating machine, is described, for example, in a special case @j#-49-.
21! This invention is an improvement on the implementation method of such a seal for a floating roof storage tank. The bag to be inserted inside is made by pasting together a breathable, flexible, thick sheet and a thin sheet, and the thicker side is wrapped in 7-ohm urethane so that the outside is 11K. Remove the air inside, seal the bag, make 7 wrinkles in the 7 band between the floating roof and the side plate, and after 9 minutes, the force of pulling out the bag will tear the thin sheet part of the bag and separate the thick sheet part. This invention is an improvement on the patented invention in order to further improve the sealing function by making it possible to completely extract the material.Other objects and advantages of this invention are as follows regarding one embodiment of the method of this invention. It will become clear from the detailed description of FIG. A sealing device attached to the pontoon is provided to seal the gap between the pontoon and the pontoon.

As shown in Figure 1, the sealing device consists of a flexible, breathable sheet material made of a plastic film such as polyethylene, moisture-proof cellophane, or polypropylene, and a thin sheet material/J. A bag 10 consisting of 9 bags is provided.

Moreover, these sheet materials 11. tJf) Mk alignment can be carried out by suitable means such as du-gao-shu**, jointing, other appropriate heating bonding, or bonding with adhesive. This bag io
Separately, a foam material 7μ having the cross-sectional shape shown in the figure is provided, which is made of a soft plastic foam having air permeability, such as soft polyurethane foam or styrene 7 ohm foam.

This foam material! As shown in the figure, the bait is made of 7 ohm material and has an auxiliary plate/S fixed to it, such as a larger set plate, so that the protruding part 16 is slightly protruding from the 7 ohm material. It can be fixed to the outer part of the floating roof together with 6, and the trench support plate/1 is a thin sheet material of bag 10/JIIK (7 ohm material) # is in bag 10e) Can be put in. Further, on the opposite side of the 7 ohm material /II, that is, on the thick sheet material of the bag 10, a bare board like a tare board is provided, and as shown in the figure, a bare board (it-16g) is provided. A %/l for drawing is attached to the.

In this way, in a bag 70 made up of 1 thick sheet material 1/M and a thin sheet material saw, 7 Om material/M1 with an auxiliary plate/J is placed.
If the P plate/1 is charged and the 7 ohm material l is inserted from the outside of the bag IO through the auxiliary plate lj and the plate 1tt.
- Then use a vacuum pump (not shown) etc. to compress the bag No. 0 and the foam material/# inside fD9! After the inside of the bag 10 is evacuated by suctioning the air, the opening of each bag 10 is closed by wrapping it with string 9 or adhesive tape.

If the 7 ohm material/I' is inflated by suction into the inside of the bag 10 and the 7 ohm material/I' is pulled, the bag io is
O Since the thin sheet material 72 part is cut and sealed from the thick sheet material it part, the bag 10 can be pulled and torn and the nine bags 10 can be completely pulled out from the scarf band 6. In this case, if there is no tear ply plate/1, the frictional resistance between the bag 10 and the 7 ohm material/It will be thick and the pull out of the bag/θ will be a solid layer. If a board etc. is provided, the frictional resistance can be considerably reduced, making it easier to pull out each bag 10.
When pulling out this bag io, do you have to use the I board / 11f - the string for pulling it out? You can pull out all the plates at once, or you can pull out only all 9 plates/l at a later time. When the bag IO is completely pulled out in this manner, the skirt 7 and the pan 6 are attached to the outer circumference 11KII of the pontoon jO to form a suitable sealing device between the side plate and the pontoon j of the floating roof V.

In this way, according to the present invention, a soft air permeable foam material is placed in a bag formed by laminating a non-air permeable flexible thick sheet material and a thin sheet material together, with the thick sheet material on the outside. After inserting the tube into the tube, the air inside the bag and the 7 ohm material is removed to compress the entire bag, and then the bag is sealed.
Then, after tearing a part of the bag and expanding the 7 ohm material, pull the bag tube and cut it at the thin sheet material part 611! A method of constructing a seal for an edematous root storage tank, which is characterized in that the bag is pulled out along with the pan I-board to make the space between the floating roof and the side panels airtight, and the upper end of the Suka 7 band is fixed to the upper end of the outer periphery of the floating roof. The duck served
5 In addition, according to the construction method of the seal for Uho horizontal storage of this invention, (1) In order to make the bag by pasting together thick and thin sheet materials, after expanding the 7 ohm material, the bag is stretched to form a thin sheet. The thick sheet material part can be removed by cutting at the material part, and the seal MID can be fully exhibited and enhanced without any inconvenience caused by the remaining bag or bag curling.

(2) By inserting a sliding plate such as a Teflon plate or an acrylic plate between the 7 ohm material and the thick sheet material of the bag, the shape of the 7 ohm material can be maintained when the inside of one bag is vacuum compressed. It is possible to create an ideal flat shape suitable for setting the bag and 7 ohm material into the scuff band.
1. (3) Such a thick and thin sheet does not require a special holding plate and further reduces the frictional resistance between the 7 ohm material and the bag when removing a torn bag, making it easier to remove the bag. By putting 7 ohm material in a bag made of materials pasted together.

Insertion and installation into the Suka 7 van can be done quickly and easily.
