The Inflatable membrane building entered the Chinese market in 1995, and it has been 26 years . As one of the important types of membrane structure, inflatable membrane structure has been rapidly developed in China in recent years. Compared with the traditional steel mixed structure building, it is becoming more and more popular in China because of its advantages such as low cost, short construction period, detachable and movable. Especially in large and medium-sized cities, the application of air membrane building can effectively solve the environmental problems of tight land for sports facilities and dust from mines.

Are air membrane buildings safe enough?

The answer is safe.

First, the air membrane building is strong enough.

1, The foundation anchorage is solid enough air membrane foundation using reinforced concrete foundation, its size, depth and reinforcement, are based on the actual site requirements have been carefully calculated, so as to ensure that the foundation of the firmness. There are generally two types of anchoring methods to connect the membrane body and the foundation. One is to pre-bury aluminium grooves in the foundation, and use corrosion-resistant wood to clamp the membrane tightly, so as to ensure the air-tightness of the membrane. The other is pre-buried ground screws, through the perforated angle iron to the membrane pressure, this way can make the connection more solid.

2, The air membrane membrane material is strong enough air membrane membrane body is made of high strength fibre cloth and polymer materials, strong toughness and tensile, strong enough. Generally, it is not easy to be damaged without sharp objects zapping, scratching or cutting.

3, The air membrane building is not affected by the harsh environment Air bearing membrane structure relies on the difference between internal and external air pressure to support the whole building, there is no bending, torsion and pressure components inside, which has the incomparable advantages of other structural systems in terms of wind resistance and seismicity resistance, and has a very good safety. and the air membrane building is equipped with an intelligent control system, when encountering bad weather, the control system will adjust the air pressure difference according to the signal feedback from the anemometer or snow load meter, in order to maintain the stability of the building. when the power grid stops supplying electricity, the backup generator can also guarantee the normal operation of the building. It is worth mentioning that the intelligent control system comes with an automatic warning function, which automatically generates alarm messages when special conditions occur in the arena equipment so that the staff on duty can deal with them in time.

Secondly, the fire rating of air membrane building is high enough.

The fireproof performance of membrane material is tested and graded according to the provisions of the current national standard "Grading of Combustion Performance of Building Materials and Products" GB 8624, and normally, it can reach B1 grade.

1, the membrane material is flame-retardant material

The membrane material used in the air membrane arena reaches B1 level fireproof requirement, which is in line with the national fire safety standards. the membrane fire performance is excellent, with the characteristics of flame retardant, no open flame does not burn, the combustion process will not produce impurities dripping, leaving the fire source after the membrane will stop burning; even if encountered a strong fire, the building can ensure that the membrane body landed 3 metres from the ground for more than 34 minutes to ensure that the evacuation of personnel time; in addition, if a fire occurs in the air membrane building, the membrane will be burned by the open fire out of the hole, due to the positive pressure in the air membrane, smoke will be due to the positive pressure inside the air membrane, the smoke will be quickly squeezed to the breach and discharged outside, minimising the fire hazard.

2. The building is equipped with fire emergency doors. The air membrane building will be designed with fire emergency doors for emergency access of personnel, and the number of emergency doors depends on the scale of the venue. The fire emergency door adopts steel door frame and aluminium door plate with sufficient rigidity. the doors are equipped with shutters and emergency lighting to ensure visual observation at any time in case of emergency.
