To provide a door device.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention takes the following technical means. That is, according to the present invention, a door body that opens and closes an opening of a chamber is suspended by a guide rail provided above the opening via a trolley and a hinge member that is bendable in the front, rear, left, and right directions. The lower part of the door body is guided by a door groove provided in the lower part of the front surface of the opening via guide rollers, and at the front surfaces of both ends of the opening part, a pillar for door pressing is erected standing in front of the door body. In a door device in which a door crimping means is arranged at a proper position on the column, the skin plate of the door body is provided only on the outer side (outer side of the chamber), and a plate-like foamed resin for heat insulation is provided in the door body. Is fitted, and rubber packings are fixed to the opening and the peripheral edge of the facing surface of the door body, respectively. In addition, it is preferable that the inside of the door body (the side opposite to the skin plate) is closed with a decorative plate (wooden plywood or the like).

[0005]

[Action]

 According to the present invention, after the door is moved to the front of the opening of the chamber and the front (outer surface) of the door main body is pressed by the door crimping means, the door main body suspends the hinge. Since the parts bend, they move smoothly toward the opening without resistance, and the rubber packing fixed to the door body is pressed uniformly against the rubber packing fixed to the peripheral edge of the facing surface of the opening. The entire circumference of the opening is sealed by the door body, and the same state is maintained.

[0006] When the opening of the chamber is sealed by the door body in this way, fluid does not flow out even if the chamber becomes a pressure chamber, and even when a high tide or a wave strikes on the coast or the like. The skin plate supports the external water pressure, and the rubber packing prevents seawater from entering the room. In addition, since a plate-like foamed resin for heat insulation is fitted inside the door body, it is possible to secure the heat retention and cold insulation functions.

Therefore, when the door body is opened, by releasing the pressing force by the door crimping means, both rubber packings are separated, the door body is separated from the opening peripheral edge, and the trolley and the hinge member are attached to the upper guide rail. By suspending via the door and moving the door body, it is possible to smoothly and easily open the door body without the rubber packings sliding on each other.
