The invention belongs to the technical field of gas film buildings, and particularly relates to a gas film-in-film structure of a gas film. The film-in-film structure of the gas film comprises an outer film and an inner film, the outer film and the inner film are installed on an outer ring foundation and an inner ring foundation through a first fixing mechanism and a second fixing mechanism respectively, a water storage weir is arranged on the top face of the outer ring foundation, and the outer ring foundation and the inner ring foundation are arranged on the outer side of a base in a surrounding mode. An outer film cavity and an inner film cavity which are independent are formed between the outer film and the inner film and between the inner film and the base respectively, the outer film cavity and the inner film cavity are connected with an air inlet pipeline through an outer film cavity air inlet pipe and an inner film cavity air inlet pipe respectively and connected with an air return pipe through an outer film cavity air return pipe and an inner film cavity air return pipe respectively, and VAVA variable air volume valves are installed at the bottom ends of the outer film cavity air return pipe and the inner film cavity air return pipe respectively, pressure of the inner film cavity is higher than that of the outer film cavity by adjusting air return amount of the two VAVA variable air volume valves, so that the inner film is flat and open, attractiveness and projection effect in a device are improved, and the position of a leakage point is quickly found out through strip-shaped edges blown on a preset film and bubbles blown in the water storage weir.
本发明属于气膜建筑技术领域，具体涉及一种气膜膜中膜结构，包括外膜和内膜，外膜和内膜分别通过固定机构一和固定机构二安装在外圈基础和内圈基础上，外圈基础顶面设有蓄水堰，外圈基础和内圈基础环绕设置在基座外侧，外膜与内膜、内膜与基座之间形成有独立的外膜腔和内膜腔，外膜腔、内膜腔分别通过外膜腔进风管和内膜腔进风管连接进气管道、通过外膜腔回风管和内膜腔回风管连接回风管，外膜腔回风管、内膜腔回风管的底端安装有VAVA变风量阀门，通过调节两个VAVA变风量阀门的回风量，使内膜腔压力高于外膜腔压力从而保证内膜平整张开，进而提高装置内部的美观度和投影效果，通过预置膜上吹起的条形边和蓄水堰中吹起的气泡，快速找出泄露点位置。
