明度が落ちるといつた欠点があつた。<Prior Art> Conventionally, underwater windows of marine structures have been constructed with double-glazed windows made of two transparent plates in consideration of safety, since they may be damaged by external water pressure or driftwood. However, the same material was used for both the outer transparent plate and the inner transparent plate. Therefore, for example, if both the inner and outer transparent plates are made of acrylic synthetic resin,
It has a relatively high impact strength and is excellent in safety, but the underwater outer transparent plate has many opportunities to clean fine particles and attached algae in the water, and at this time it is easily scratched and its transparency is reduced. It had In addition, when both the inner and outer transparent plates are made of tempered glass, the underwater outer transparent plate is less likely to be scratched when cleaning the attached algae, but the impact strength is slightly reduced, which poses a safety problem. Furthermore, when a window has a double structure, moisture in the gap between the inner and outer transparent plates condenses on the opposing surfaces of the two transparent plates due to the temperature difference between the water and the inside of the structure, reducing transparency. I had a lot of flaws.

The inner transparent plate 5 made of acrylic synthetic resin and the outer transparent plate 4 made of tempered glass are fitted with neoprene rubber gaskets 11 and 12 having a U-shaped cross section on their outer peripheries. The part is attached to the flange 8 of the window frame 3 through the packing 11.
The outer peripheral portion of the inner transparent plate 5 is tightly attached to the support frame 10 via a packing 12. Furthermore, both the transparent plates 4 and 5 have the two packings 11,
12 are brought into close contact with each other via the spacing frame 13, thereby forming a sealed gap 6 between both transparent plates 4 and 5. And both transparent plates 4 and 5

れている。 Furthermore, an injection hole 20 for injecting an inert gas 7 such as nitrogen gas and an air vent hole 21 are formed in the spacer frame 13. This gas 7 is sealed so that the pressure in the gap 6 is slightly lower than the water pressure, thereby alleviating the water pressure applied to the outer transparent plate 4 made of glass. Furthermore, on the underwater side of the window frame 3, there is an annular projection 23 that receives the metal blind cover 22 for construction when both transparent plates are replaced.
is formed. And the water drain hole 2 is in the protrusion 23.
4 is formed. In addition, 25 is a watertight gasket arranged on the outer periphery of the blind lid 22, and this gasket 2
5 is brought into close contact with the projection 23 by water pressure.

保持できる。 In the above configuration, the transparent plates 4 and 5 are attached by first fitting the gaskets 11 and 12 to the outer transparent plate 4 and attaching them so that they come into close contact with the inner surface 8a of the flange 8 of the window frame 3 and the support frame 9. Next, the spacer frame 13 and the inner transparent plate 5 with the gasket 12 are successively brought into close contact with the window frame 3. Then, the press frame 14 is brought into contact with the packing 12,
Both transparent plates 4 and 5 are brought into close contact with the window frame 3 by pressing them toward the flange 8 side by the tightening device 15. Next, with the air vent hole 21 in the gap 6 of both transparent plates 4 and 5 open, gas 7 is injected through the injection hole 20, and when the moisture-containing air is exhausted, the air vent hole 21 is opened.
1 is closed, and the gap 6 is filled with an inert gas 7 to make it approximately equal to the water pressure, and the injection hole 20 is closed. In this way, even if a temperature difference occurs between the water and the indoor side of the structure 1, condensation will not form on the transparent plates 4 and 5 since the void 6 does not contain moisture. In addition, the outer transparent plate 4 made of glass has an improved strength because the water pressure is offset by the gas pressure in the void 6. Also, since the outer transparent plate 4 is made of glass, algae and the like that adhere to the outer surface of the outer transparent plate 4 are less likely to be damaged during cleaning, and transparency can be maintained.
また両透明板４，５を水中で取替える場合は、
水中から盲蓋２２を窓枠３の突起２３に当接し、
締付装置１５を緩めて両透明板４，５を取外す。
そうすると、水圧により盲蓋２２は窓枠３の突起

る。 Also, when replacing both transparent plates 4 and 5 underwater,
The blind cover 22 is brought into contact with the protrusion 23 of the window frame 3 from underwater,
Loosen the tightening device 15 and remove both transparent plates 4 and 5.
Then, the blind cover 22 comes into close contact with the protrusion 23 of the window frame 3 due to water pressure, preventing water from entering the room and maintaining a watertight structure. After attaching both transparent plates 4 and 5, the blind cover 22 is removed by opening the drain hole 24 of the protrusion 23, and the replacement work can be completed.

It is hard to get scratched even when cleaning, and by filling the gap between both transparent plates with an inert gas at a pressure intermediate between water pressure and indoor pressure, both transparent plates are prevented from being damaged by the temperature difference between the water and the room. To provide an underwater window structure which can prevent dew condensation, can maintain its transparency, can reinforce the strength of an outer glass transparent plate, and is excellent in safety.
