Description

[0001] The present invention relates to a dual sliding blast proof door with an inner door,

More particularly, the present invention relates to a sliding explosion-proof door installed in a CBC building or a governmental dissemination facility or a biochemical research institute. More particularly, the present invention relates to an explosion-proof explosion preventing biohazard, The present invention relates to a double sliding door having an internal airtight structure for easily loading and unloading heavy equipment having a relatively large volume and area such as an emergency generator or a filter installed in the building.

Generally, the sliding explosion-proof door installed in the CBR building, the government dissipation facility, and the air-fueled antenna tower must have the strength and rigidity to withstand the strong external explosion unlike the general door, and requires very high airtight performance.

Sliding door which is installed on the roof floor or the first floor is equipped with a rubber seal in order to achieve high airtightness. Due to the friction coefficient of the rubber seal, it is difficult to open and close the door. The rubber is damaged and it is difficult to airtight.

To solve these problems, the rubber seal is now specially manufactured to fill air inside the rubber seal to ensure the airtight performance. The manufacturing cost is higher than that of the ordinary rubber seal, and it is difficult to install the rubber seal. It is difficult to install the pneumatic related equipment inside the door.

Such a rubber seal using air is not a problem in a place where external physical shock does not occur. However, since the CBC building and the dissipating facility of the government are constructed for special purpose in preparation for an external attack, If the part of the rubber seal is damaged due to the explosion, there is a problem that the airtightness can not be ensured because the expanded rubber seal air is lost, and in addition, when the pneumatic equipment fails to operate during a power failure, There is a problem.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the related art by providing an internal door capable of exhibiting airtightness performance in a sliding explosion-proof door so that an outer door sufficiently resists against external bombardment, Since the rubber seal does not interfere with the door frame when the sliding door is opened and closed, it is easy to open and close the door of the explosion proof door. Also, when the sliding door is closed, the inner door moves vertically downward so that the outer door can resist the explosion. The double sliding door is provided with an internal airtight structure which can completely seal the opening by pressing the rubber seal provided on the door frame with the inner door while the four door latches are plugged.
