Small damage to the air dome will not affect the safety of the building itself. Timely repair can solve the problem.

If a large hole is punched (the area is more than 1m2), the air pressure inside the building will change, the control system will alarm, the management personnel will evacuate the building in time, and repair the damaged place, generally 30 minutes to an hour can be repaired. Building safety will not be affected.

American standard: when all doors are opened, the average height of the air-dome building falls to 2.5 meters for no less than 30 minutes, giving people enough time to escape.

Our own example: Foxconn plant project, all the inflatable equipment stopped, all the doors do not open, the dome fell to the height of 5 meters is about 4 hours.

The building quotation requires the owner to provide the following information: site area, use of the air dome, permanent or seasonal, grade of membrane materials, internal configuration: heating, air conditioning, lighting, insulation cotton, number of emergency doors, number of revolving doors, etc.

As it is supported by the difference of internal and external air pressure, the air dome cannot be made into any shape. The most common shape is rectangular, oval or circular (air dome is supported by air, and there is no column or beam inside, so its top is not angular, it is in arc shape).

It can also be made into a single layer, such as coal shed and ordinary factory building, the double-layer insulation effect will be better, at the same time, it can be filled with insulation cotton between the two layers of dome. The third floor can completely eliminate the hidden danger of cold bridge, and has an absolute advantage in snow and ice sports.

As a building with high requirements on air tightness, the airdome structure does not have too many entrances and exits, which is not suitable for large flow of people and intensive activities in a long time, but suitable for the training hall.

If you need build large venues, the air dome building needs to be integrated with traditional architecture, such like revolving door emergency door need stand part in traditional architectural design, the air dome can be used as a rooftop, greatly reduced the investment for stadium. We once worked in Hunan Li County stadium project comparison, using air dome roof not only half reduced the construction cost, but also the future of energy consumption is reduced by half.

Suitable for large space requirements, but do not need to be hung on the top of the plant machine type. Such as warehouse or electronic plant, etc.

Air dome has a cost advantage in constant temperature and humidity of clean workshop. Due to air dome characteristics: Indoor positive pressure. That it is difficult for particulate matter from outdoor air to enter the indoor environment. It can easily achieve 100,000-grade or even 10,000-grade ground cleaning by adding primary, medium and high efficiency filter sections in our mechanical units as required. Even, we still have cost benefits that traditonal construction can not compare with. 

Yes. We have a lot of cases.
